Description:
A HANDHELD TOOL

The technical field of the present application generally re lates to handheld tools, in particular to the forming of handheld tools or utensils from a sheet-shaped blank.

Handheld tools or utensils made of sheet-shaped materials are used in general as low-cost alternatives to tools made from bulk materials .

US 20140238987 A1 describes a foldable spoon with a spoon cup section and a spoon handle. The spoon handle, including apex folds and valley folds, and the spoon cup section are formed from a single sheet of foldable material.

Singapore Registered Designs 30201703913Y and 30201703914W re late to a spoon.

Singapore Registered Designs 30201703916PY and 30201703915R relate to a fork.

The object of the present application is to provide an im proved user and environment friendly form-stable hand-held tool which can be easily and cost-effectively manufactured.

According to a first aspect, a blank for forming a handheld tool is provided. The blank has a flat, elongated shape. The blank can have an essentially symmetric shape, in particular with respect to a longitudinal symmetrical axis . In the fol lowing, if not specified differently, a symmetry or symmet rical arrangement refers to a symmetry or symmetrical arrange ment with respect to the symmetrical axis of the blank. The blank comprises a top surface, a bottom surface opposite to the top surface, a first longitudinal end, a second longi tudinal end, a first side end, and a second side end. A cir cumferential cutting edge of the blank comprises a rear edge at the first longitudinal end, a front edge at the second lon gitudinal end, a first side edge at the first side end and a second side edge at the second side end.

The blank further comprises at least one essentially continu ous upward bending line extending between the side edges of the blank, with a first upward bending segment, a second up ward bending segment, and a connecting segment. The upward bending segments extend at an oblique angle inwards from re spective endpoints at the side edges of the blank, pointing along a longitudinal direction towards the front edge of the blank and providing a vertex with a blunt and at least par tially rounded shape.

"Essentially continuous" means in this context that the lines may also comprise continuous sections which are separated by breaks or discontinuities .

Due to the arrangement of the upward bending line, three main sections of the blank along the longitudinal direction can be distinguished: A handle section extending from the rear edge to the endpoints of the straight segments of the upward bend ing lines at the side edges, a functional section extending from the tip of the front edge to the vertex, and an interme diate section between the handle section and the functional section .

The shape of the functional section may be customized and may significantly vary depending on the specific purpose of the tool and/or intention of the customer. In particular, the functional section of the blank may have an essentially smooth or rounded contour line for forming spoons or spoon-like tools like scoops, shovels, funnels or similar.

The functional section may also have a tined contour line for forming forks or forklike tools of various geometries.

The functional section may further comprise holes or perfora tions of different number and size for forming strainers or filters out of the blank.

The blank further comprises a first downward bending line ex tending between the rear edge and the first upward bending segment, and a second downward bending line extending between the rear edge and the second upward bending segment, as well as a middle area or middle lane extending between the downward bending lines, the upward bending line, and the rear edge.

The bending lines serve as bending aids which facilitate the bending or folding of the blank in a predetermined manner, fa cilitating the folding of the blank to form a handheld tool with the desired form.

Due to the middle area extending between the downward bending lines, the upward bending line, and the rear edge, an elon gated middle lane between the downward bending lines is formed which is free of bending lines. After the tool is formed, the middle lane contributes to the stability of the tool since, in the folded state, the middle lane forms or builds an elongated plateau between the two downwards bent portions of the blank, which serves as a carrying construction and gives a particular stability to the tool. The blunt and at least partially rounded shape of the vertex serves for distributing the pressure from the frontal part of the tool over the perimeter of the vertex. This means that the risk of damaging the blank by the compression stress can be reduced. The risk of injuring of persons by the sharp edges at the vertex can be reduced as well .

In other embodiments, the first downward bending line extends between the rear edge and the first side edge and the second downward bending line extends between the rear edge and the second side edge in such a way that two wings at the rear edge of the blank are provided.

The corner wings at the rear edge of the blank can be used to form a comfortable handle for the handheld tool.

The downward bending lines may be arranged in such a way that a widening of the middle area at the connecting segment is provided. In particular, each one of the downward bending lines may comprise an essentially straight longitudinal seg ment and a curved segment, the curved segments forming the widening of the middle area or middle lane. The longitudinal arrangement of the straight segments of the downward bending lines in the region between the rear edge of the blank and the vertex provides a particularly good protection for this region which can serve as a carrying construction or spine of the tool .

The straight segments of the downward bending lines may extend to the rear edge of the blank. Extending the straight segments of the downward bending lines to the rear edge of the blank facilitates an accurate folding along the downward folding lines, especially in the region of the rear edge. At the point or points of the rear edge where the straight segments of the downward bending lines end, one or more inden tations in the rear edge can be provided.

The indentations at the end of the downwards bending lines can substantially facilitate the bending of the blank at the rear edge .

At the same time, the widening of the vertex can serve for lo cal stress reduction in the vertex region and thus result in a more stable tool.

The angle between the first upward bending segment and the second upward bending segment may be chosen in a range of 20° to 66°, more specifically of 26° to 35°.

By choosing the angle between the upward bending segments in this range, a broad variety of customized useful tools can be formed .

Each one of the downward bending lines may meet the upward bending line at a respective junction point adjacent to the vertex .

By providing for the junction points between the downward bending lines and the upward bending line in the vicinity of the vertex, the forming of the tool out of the blank can be facilitated by improving the controlled foldability in the vertex area.

At the junction points, the angle between the upward bending line and the respective downward bending line may be essen tially perpendicular or lie in the range of 60° to 90°, more specifically of 80° to 90°. Due to choosing or predefining the angle between the upward bending line and the respective down ward bending line at the junction points, building of folds with sharp angles can be avoided, and the controllable folda- bility of the blank in the vertex region can be improved.

The blunt and at least partially rounded vertex may have an essentially smooth shape. In particular, the vertex may have a circular shape or a flat tip with rounded corners. The smooth shape of the vertex can smoothen the tension distribution in the blank such that local stress maxima in the vertex region can be reduced.

At least one of the bending lines may be provided by an essen tially continuous bending groove formed on at least one sur face of the blank.

Depending on the basic material of the blank different tech niques for creating the groove can be applied.

In particular, the groove may be scored or coined in the re spective surface of the blank. The grooves may also be formed by application of pressure, cutting, by laser ablation, or similar .

By scoring or coining of the grooves in the blank, the bending lines desired pattern can be easily provided.

For the downward bending lines, the groove may be provided on the top surface of the blank.

By providing the groove on the top surface of the blank, the blank can be weakened along the bending lines in such a way that the blank is particularly easily bendable or foldable downwards along the bending line. For the upward bending line, the groove can be provided on the bottom surface of the blank.

By providing the groove on the bottom surface of the blank, the blank can be weakened along the bending lines in such way that the blank is particularly easily bendable or foldable up wards along the bending line.

The groove for the bending lines may have a rounded or essen tially rectangular profile with an aspect ratio, i.e. the ra tio of its depth to the width between 1 and 5, more specifi cally between 2 and 4. The depth of the score may be in the range of 10 to 30 per cent of the thickness of the blank, de pending on the chosen materials.

At least one of the bending lines may be also formed by providing - in particular, by printing - an additional mate rial layer along the predefined paths of the bending lines. By providing the additional material layer, which in general can have mechanical characteristics, which are difference from those of the basic material of the blank, the bendability of the blank can be locally modified in such way that the blank is more easily bendable in one direction than in another di rection thus facilitating the bending or folding of the blank.

The profile and the exact dimensions of the groove depends in general on the chosen material, on the thickness, and on the purpose of the blank.

The blank may comprise compostable and/or recyclable materi als, in particular approved or certified by the Food and Drug Administration (FDA), Sustainable Forestry Initiative (SFI), Forest Stewardship Council (FSC), American Society for Testing and Materials (ASTM) to name but a few.

In the following, a non-exhaustive list of possible materials is provided:

- FSC/SFI certified - ASTM D6868 compliant for Compostabil- ity and Recyclable. Such materials (e.g. Cellulose Nano fibre - NCF / Microfibrillated -MFC paper) are durable, water-repellant, tear-resistant,

- BPA (Bisphenol A) -free, latex-free, TPR (Thermoplastic Rubber) and TPE (Thermoplastic Elastomer) ,

- Premium food grade Silicone (SR/LSR) , an elastomer, char acterized by a wide temperature resistance range of -103° F to 500° F. It is non-stick, non-toxic, highly tensile, flexible, and has a low compression set. Further, it is odorless, tasteless, mould and bacteria-resistant and hy drophobic .

The blank material can also comprise FRP (Fibreglass Rein forced Plastic) , microlattice, Dyneema, Polypropylene (PP) , High-Density Polyethylene (HDPE) , Low-Density Polyethylene (LDPE) , Polycarbonate (PC), nano-tubes to name but a few.

In particular, for a paper-based blank, the material can have a material area density in the range from 230 g/m2 to 350 g/m2 or from 250 g/m2 to 400 g/m2.

For paper-based blank materials, the orientation of the paper grains can be chosen essentially parallel to the longitudinal direction of the blank.

Due to the longitudinal orientation of the paper grains, the robustness of the tool formed out of the blank can be in creased . At different positions, and in particular in the handle sec tion, i.e. between the rear edge and the endpoints at the side edges of the blank, elevated portions or bumps of essentially round and/or elongated shapes can be provided.

Due to the bumps or elevated portions, the robustness of the tool can be improved. Furthermore, by providing the bumps or elevated portions in the handle section of the blank, the grip of the handle of the tool can be improved, such that the tool can be securely grasped.

The blank may have an essentially tapered shape, such that the width of the blank at the rear edge is smaller than the width of the functional section. In particular, the side edges can comprise essentially straight segments being arranged under an oblique angle with respect to the symmetrical axis in such way that the width of the blank at the rear edge is smaller than the maximum width of the functional section, in particular be tween the tip of the front edge and the vertex.

Such a tapered form of the blank results in general in a tool with a narrower handle and a wider functional section. At the same time, the tapered form may be used to save material dur ing the manufacturing of the blank. In particular, in the bulk production of the blanks out of the same worksheet, cutting the blanks with alternating orientation can lead to substan tial material savings in the case of tapered shape of the blank .

In some embodiments, additional bending lines are provided, essentially parallel to the bending lines. In particular, ad ditional downward bending lines can extend in parallel to the symmetrical axis in the region of the middle lane. By providing the additional bending lines, the bending may be shared over the plurality of the downward bending lines in such way that the bending angle at each of the bending line, and thus the stress of the blank, is reduced.

Further, a blank with an essentially flat, elongated shape for folding to form a handheld tool is provided. The blank com prises two bendable side wings, in particular in a handle sec tion of the blank, a middle lane or middle lane region ar ranged along a longitudinal symmetrical axis of the blank, and a bow which partially circumvents one end of the middle lane. The bow can in particular at least partially comprise a func tion section or functional part of the tool which is to be formed .

The side wings and the middle lane are at least partially de marcated by downward bending lines, and the bow is demarcated from the middle lane and from the side wings by an upward bending line is such way that between the middle lane and the bow, a vertex of the upward bending lines is formed. A bending of the side wings from the plane of the blank, in particular with respect to the middle lane, then results in a tensile stress along the circumference of the bow and in a compression stress in the vertex region of the bow.

In some embodiments, a middle channel or spine is formed from the middle lane or middle lane region in the course of bending of the side wings of the blank.

Due to the tensile stress and the compression stress caused by the bending of the side wings, the plane geometry of the bow is energetically not favourable, such that a mechanical fluc tuation, such as a manual tilting of the tip of the bow in one or another direction from the initial plane can lead to at least partial release of the stress, thus leading to a stable three-dimensional shape of the tool.

In particular, the blank may comprise a rear edge and a tip, and the middle lane can extend in the region between the rear edge and the vertex, reaching the rear edge and/or the vertex.

The upward bending line may comprise two upward bending seg ments connecting endpoints at the side edges of the blank with the vertex. In particular, the upward bending segments can be formed as essentially symmetrically arranged and essentially continuous straight segments.

Due to the straight sections of the upward bending line be tween the endpoints and the vertex, the stress of the material introduced by bending of the blank for forming the tool can be reduced .

By simultaneously moving the side wings away from the plane of the blank, the endpoints at the side edges are moved or dragged with the side wings . This means that the endpoints leave the plane of the blank, in particular that of the middle lane, and move essentially in a plane perpendicular to the symmetrical axis of the blank, causing a deformation of the bow .

The endpoints can be useful to see whether the side wings are bent correctly by checking whether, in the state of the formed tool, the endpoints meet.

The vertex can have a smooth, at least partially rounded or piecewise rounded shape. Due to such a shape of the vertex, local tensions in the blank material as well as the risk of injuring of the user can be reduced.

The middle lane can have a widening at an end proximal to the vertex .

By widening the middle lane at the vertex, the middle lane provides a wide support for the vertex to withstand the com pression stress from the side of the bow.

In particular, due to the widening of the middle lane at the vertex and due to the blunt or rounded shape of the vertex, the pressure from the frontal part of the bow is distributed over the perimeter of the vertex in such way that the risk of damaging the blank by the compression stress in the vicinity of the vertex is reduced.

The blank, especially the side wings of the blank, may be equipped with magnets. In particular, stripes of magnetic ma terial can be laminated on or embedded in the side wings of blank .

The magnets in the side wings can keep the side wings together or in a folded state even if the tool is not actually in use and hence no bending force is applied by the user.

According to another aspect, a process for manufacturing a blank for forming a handheld tool is provided. This process comprises providing a flat sheet of workpiece of worksheet.

For the worksheet, any material can be used which is suitable for the manufacturing process according to the aspect, and which is in particular suitable for usage according to any purpose of the tool which is to be formed out of the blank. The worksheet can in particular be paper-based, silicone- based, metal-based, or similar.

In particular, the worksheet can comprise compostable and/or recyclable FDA-approved food-safe materials, including but not limited to paper, especially with an area density in the range from 230 g/m2 to 350 g/m2.

The process further comprises providing bending aids in the form of downward bending lines and in the form of at least one upward bending line at predefined positions of the workpiece of the workpiece, as well as cutting the workpiece according to a predefined pattern in such way that a blank of essen tially symmetric elongated shape is cut out. By folding of the blank which along the upward bending line and along the down ward bending lines a handheld tool of predetermined shape is formed .

For cutting out of the blank out of the workpiece, a die-cut- ting processes may be used. The die-cutting process is espe cially suitable for cutting many pieces of the same shape by using die-cutting tools.

The bending lines may be formed by providing surface grooves by scoring or coining of the worksheet. For cutting out the blank and/or for providing of the grooves, laser cutting may be used. By using the laser cutting, the cutting pattern can be easily adjusted or modified.

Coining the grooves is especially suitable for mass production of blanks with fixed design. By cutting out blanks with alternating orientation from the same worksheet a substantial amount of the worksheet material can be saved in the case of blanks with tapered shape.

The workpiece may comprise paper with a grain-orientation which is essentially parallel to the longitudinal axis of the blanks .

Due to the longitudinal orientation of the paper grains, ro bustness of the tool formed out of the blank can be improved.

The process may further comprise formation of elevated por tions in the blank. The elevated portions or bumps can serve for additional robustness of the handheld tool and can also improve the grip for grasping and holding by the user. The bumps can be coined or blind embossed in the blank. Thus, the bumps can be easily formed.

The process may further comprise providing a reinforcement in the form of one or more reinforcement layers of the blank. In particular, the reinforcement layer can comprise silicon, metal or plastic provided at critical areas of the blank which are exposed to the stress during forming or usage of the tool.

The reinforcement may comprise an embedded layer, i.e. a mate rial layer which is embedded in the worksheet material. The reinforcement layer may comprise a moulded, in particular an extrusion-moulded, silicone layer.

The reinforcement may comprise one or more embossed struc tures, similar to those of the bumps formed in the blank.

The process may further comprise providing colour marking of the blank. In particular, the colour marking can be used for marking the folding lines as well as the functional sections for ease of usage.

The process may be carried out as a batch process in which two or more blanks are produced out of one workpiece.

By using a batch or bulk process, the time and material needed for manufacturing the blank can be reduced.

In particular, in a batch process the blanks may be produced from the workpiece in such an arrangement that the blanks are parallel to each other while adjacent blanks are oriented in opposite directions .

Due to such arrangement, in the case of blanks with tapered shape, more blanks can be accommodated side by side on the same area of the workpiece.

According to another aspect, a handheld tool is provided which is formed by folding the blank according to the first aspect.

The particular shape and dimensions may vary depending on the specific design and purpose of the tool, as well as on the chosen materials.

In particular, dependent on the specific design of the blank, different kinds of spoons may be formed, like teaspoons, cof fee spoons, dessert spoons, salad spoons, tasting spoons, soup spoons, big spoons to name but a few. Similarly, a vast vari ety of kitchen utensils or fork-like tools can be formed by designing the blank accordingly.

By changing the bending direction of the functional part, "re versed spoons" may be formed which can be used as a funnel or utensil for soft-foods such as yogurt, sorbet, soya bean curd to name but a few. Such reversed tools are also characterized by robustness and form-stability, since an energetically fa vourable stable configuration can also be achieved when the front portion of the functional section is bent in the same direction with respect to the plane of the middle lane as the side wings.

In the following description, details are provided to describe embodiments of the application. It shall be apparent to one skilled in the art, however, that the embodiments may be prac ticed without such details.

The description of one part applies by reference to another similar part, where appropri ate, thereby reducing repetition of text without limiting the disclosure .

Figs. 1 and 2 show a blank 1, which is intended for folding to form a handheld tool according to an embodiment.

The blank 1 is intended for folding to form a handheld tool and it has a flat, elongated, and essentially symmetric shape, its symmetrical axis A being indicated as a dash-dotted line in the figure.

The blank 1 comprises a top surface 2, a bottom surface 3 op posite to the top surface 2, a first side edge 4, a second side edge 4' opposite to the first side edge 4, a front edge 5 , and a rear edge 6.

The blank 1 essentially comprises three sections - a handle section 7, a functional section 8, as well as an intermediate section 9 which connects the handle section 7 with the func tional section 8.

The blank 1 also comprises a bending aid in the form of down ward bending lines 10, 10' and an upward bending line 11 for facilitating bending or folding of the blank 1 in a predefined manner for forming the handheld tool with the desired form.

The upward bending line 11 which is shown as a dashed line has a shape of a smooth continuous line extending between two op posite edges 4, 4' of the blank and comprising two essentially straight upward bending segments 12, 12' . Each one of the straight upward bending segments extends from a respective side edge 4, 4' at the handle section 7 of the blank 1 over the intermediate section 9 towards the functional section 8 under an oblique angle with respect to the symmetrical axis A of the blank 1 such that the both upward bending segments 12, 12' are connected over a middle or connecting segment 13 form ing a blunt vertex at the functional segment 8 of the blank 1.

Depending on the specific embodiment, the shape of the vertex 13 may be different. In the embodiment of Fig. 1, the vertex has an essentially circular shape with a curvature radius of approximately 5 mm.

The downward bending lines 10 comprise two symmetrically ar ranged smooth continuous lines which are shown as solid lines, each comprising a straight segment 14, 14', extending from the rear edge 6 of the blank 1 towards the vertex 13, and a curved portion 15, each one of the curved portion 15 of the downward bending lines 10 ending at a respective junction point 16 at the upward bending line 11 in the vicinity of the vertex 13.

The straight segments 14, 14' of the downward bending line 10 are extending longitudinally on both sides and close to the symmetrical axis A, such that a stripe extending from the rear edge 6 to the vertex 13 is formed.

In this embodiment, the straight portions 15 are parallel to each other and to the symmetrical axis A of the blank 1. Thus, the central stripe or middle channel has an essentially con stant width over its whole length, except in the vertex re gion, in which the middle channel widens due to the curved portions 15 of the downward bending lines 10.

At the junction points 16, the upward bending line 11 lie es sentially perpendicular to the downward bending line 10. In some embodiments, the angle between the upward bending line 11 and the downward bending line 10 at the junction point 16 is between 60° and 90°, more specifically between 80° and 90°.

The upward bending segments 12, 12' of the upward bending line 11 form or build an angle of approximately 26°.

The length of the tool is approximately 130 mm while its width is about 40 mm. The handle section 7, the intermediate section 9, and the functional section have lengths of approximately 40 mm, 63 mm, and 27 mm, respectively.

Depending on the purpose and on the design of the tool, the angle between the upward bending segments 12, 12' of the up ward bending line 11 may vary, in particular, from approxi mately 20° up to approximately 66°.

The vertex 13 of the upward bending line 11 and the curved portions 15 of the downward bending line 10 show a circular curvature with approximately the same curvature radius as the vertex 13. The curvature radius in this embodiment is approxi mately 5 mm.

In the handle section 7 of the blank 1, elevated portions or bumps 17 of essentially round shape are provided.

At the ends of the straight segments 14, 14' of the downward bending line 10, indentations 18 are provided in the rear edge 6 of the blank 1. The rear edge 6 is essentially straight and has rounded corners 19. The radius of curvature of the rounded corners is approximately 2 mm.

The side edges 4 of the blank 1 are straight and slightly in clined with respect to the symmetrical axis A of the blank in such a way that the width of the blank 1 at the rear edge 6 is smaller than the width of the functional section 8 of the blank 1.

In this embodiment, the front edge 5 has a circular shape with a curve diameter equal to the width of the functional section

The depth of the indentations 18 in the rear edge are approxi mately 2 mm.

The length of the blank 1 is approximately 130 mm and the max imum width is 40 mm.

In the handle section 7 adjacent to the intermediate section 9 elongated transversal structures 20 are provided.

In this embodiment, the transversal structures 20 are provided in a shape of elongated bumps lying perpendicular to the sym metrical axis A of the blank 1.

The bending lines 10, 10' , 11 are formed as bending grooves scored in a surface of the blank.

In the case of the downward bending line 10, 10' , the bending groove is provided on the top surface 2 of the blank 1.

In the case of the upward bending line 11, the bending groove is provided on the bottom surface 3 of the blank 1.

Depending on the specific embodiment, the bumps and/or the bending aids may be provided with colour marks in order to fa cilitate the recognition of the handle section and/or the bending aids . In the present embodiment, the blank 1 is a blank for a dis posable spoon made from paper which is approved by the Food and Drug Administration (FDA) . The area density of the paper is approximately 300 to approximately 400 g/m 2 .

As a basic material of the blank various materials may be used, such as paper, cardboard, metal, silicone, or any other suitable material .

In particular, the blank may comprise compostable and/or recy clable FDA-approved food-safe materials, including but not limited to paper, especially with an area density in the range from about 200 g/m 2 to about 350 g/m 2 and to paper an area den sity in the range from about 350 g/m 2 to about 500 g/m 2

The depth and the width of the bending scores depends in gen eral on the material, thickness, and the purpose of the blank.

The blank 1 can be easily shaped into a handheld tool by manu ally bending it along the bending lines 10 and 11.

In particular, due to the bending scores provided on different surfaces of the blank 1 along the bending lines 10, 10' and 11, it is particularly easy to bend the blank 1 downwards along the downward bending lines 10 and upwards along the up ward bending line 11.

The bending lines 10, 10' and 11 demarcate four separate areas of the blank 1, including two side wings 30 arranged symmetri cally with respect to the symmetrical axis A of the blank 1, a middle lane 31 corresponding to the central channel along the symmetrical axis A, and a bow 32 which includes the functional section 8 and extends over the intermediate section 9 and par tially circumvents the vertex 13. The side wings 30 extend from the rear edge 6 of the blank 1 over the handle section 7 and the intermediate section 9 to the vertex 13. At the side edges 4 of the blank, the side wings 30 and the bow meet at respective endpoints 21, 21' which are endpoints of the upward bending line 11.

The downward bending lines 10 demarcate the border between the side wings 30 and the middle lane 31.

In order to shape the blank 1 into a handheld tool, the side wings 30 of the blank 1 are bent downwards (away from the viewer) with respect to the middle lane 31. The downward move ment of the side wings 30 is indicated by downward movement arrow symbols 33.

At the same time, by bending or folding the side wings 30 downwards with respect to the middle lane 31, an elevated plateau along the middle lane 31 is formed, which lies between two brinks resulting from the folding of the blank 1 along the downward folding lines 10.

Due to the form-stability of the middle lane 31, in the begin ning of the bending process, the longitudinal dimensions of the blank remain essentially the same and the endpoints 21,

21' move essentially perpendicular to the symmetrical axis A of the blank 1 or to the middle lane 31. This means that along the circumference of the bow 32 a tensile stress or tension is building up, which extends along the front edge 5 and the side edge to the respective endpoint 21, 21' . The tensile stress along the circumference of the bow 32 is shown as bended ar rows 40. Simultaneously, with the bending of the side wings 30 down wards, the endpoints 21, 21' at the side edges 4 are also moved or dragged down. This means that the endpoints 21, 21' leave the plane of the drawing or the plane of the middle lane 31 and move down, travelling essentially in a plane perpendic ular to the symmetrical axis A of the blank, resulting in a deformation of the bow 32.

In fact, due to the dragging down of the endpoints 21, 21' by the wings 30, the bow 32 ceases to be a plane or essentially two-dimensional object and it becomes a three-dimensional ob ject instead.

With the formation of side brinks along the upward bending line 11, the middle lane 31 provides a form-stable carrier construction of the tool. If the tool is provided as a spoon, in use, the middle lane 31 together with the side brinks acts to prevent cutting of mouth or lips of the user.

By continuing the downward bending of the wings 30, the ten sile stress along the circumference of the bow 32 grows, pull ing the tip 22 of the blank 1 towards the vertex 13 against the middle lane 31, resulting in an essentially axial compres sion force (indicated by a wide arrow 41) in the region of the vertex 13.

With the widening of the middle lane 31 at the vertex 13 and due to the tapered shape of the vertex 13, the compression force from the frontal part of the bow 32 is distributed over the width of the vertex 13 in such way that the compression stress at the perimeter of the vertex 13 is reduced. With the reduction of the compression stress at the vertex 13 damage to the vertex 13 or vertex region can be avoided.

With the tensile stress and the central compression stress caused by the bending of the side wings 30, the planar geome try of the frontal part, in which the frontal part or the tip 22 remains in the plane of the middle lane 31, becomes ener getically unstable.

By manually tilting the tip 22 of the functional section 8 up wards, the frontal part of the bow 32 can flip upwards and can take a stable position, in which the circumferential tension along the tension lines 40 is minimized. The upward movement of the front part of the bow 32 is shown by an upward movement arrow symbol 34.

After flipping upwards, the frontal part of the bow 32, and accordingly the functional section 8, takes a stable position.

In particular, by flipping upwards, the frontal part of the bow 32, the functional section 8 obtains a cup shape, the ver tex 13 being the deepest point of the cup, and the blank 1 be comes a form-stable tool which in this embodiment is a small spoon .

As long as the side wings are kept bent down, especially by holding the tool in the hand, any deviation from this final shape would be energetically unfavourable, since it would in crease the tensile stress along the circumvention of the bow 32.

Thus, by folding the side wings 30 downwards with respect to the middle lane 31, a form-stable handheld tool is formed. The bumps 17 and the transversal structures 20 can serve as grip structures or grippers for easier handling of the tool by the user.

The blank of Fig. 1 can be easily manufactured. Firstly, a flat worksheet or workpiece comprising paper, cardboard, plas tic, metal or any suitable material is provided.

The bending lines may be scored or coined in the blank sheet of the blank material at predefined positions in correspond ence with the specific embodiment of the blank.

The bumps 17 and the transversal structures 20 may be embossed or coined, by pressing the worksheet between two complementary tools of appropriate shape. In some embodiments, the bumps and/or the transversal structures are blind-embossed in the worksheet .

The blank 1 is cut out of the worksheet, in particular by means of die-cutting.

The formation of the bending lines 10, 11, bumps 17, transver sal structures 20, and/or die cutting can be performed on a bigger area of a worksheet in such way that more than one blank out of a single panel is produced. Such a batch or bulk production can save time and costs in the manufacturing pro cess .

A rolling machine, in particular a die-cutting roller, may be used for carrying out at least one of the previously mentioned operations .

In some embodiments, one or more reinforcement layers are pro vided, in particular of the middle lane 31. The reinforcement may be formed as an additional material layer provided along the middle lane. The additional material layer may comprise metal, thermoplastic or thermoset material. It may be laminated, especially glued, onto the on the top surface 2 or on the bottom surface 3 of the blank 1. In some embodiments, reinforcement is embedded in the blank 1.

The reinforcement may comprise fibres embedded in the blank material or applied on one of the surfaces of the blank mate rial .

In a special embodiment, the blank 1 of Fig. 1 include a bend ing line or a die cut line such that the unfolded or flat blank 1 can act as a bookmark. Advertisement or useful infor mation can also be printed on the blank 1, thereby allowing a user of the blank 1 to have quick and easy access to such data .

Fig. 3 shows a schematic top view of a blank la for folding to form a handheld tool according to another embodiment.

The blank la of Fig. 3, in its structural and functional parts, essentially corresponds to the embodiment of Fig. 1.

One difference to the embodiment of Fig. 1 lies in the spe cific shape of the blank la, in particular in the shape of the vertex 13 and of the tip 22. Further, different to Fig. 1, the straight segments 14 of the downward bending lines 10 are not parallel but meet at a single indentation 18 at the rear edge 6 of the blank la. Due to the arrangement of the downward bending lines 10, the middle lane 31 narrows towards the rear edge 6 turning essen tially into a single line at the rear edge 6.

The vertex 13 has a flat tip and rounded corners. The junction points 16 between the downward bending lines 10 and the upward bending line 11 lie slightly apart from the rounded corners of the vertex on the straight segments 12 of the upward bending line 11. The angle between the straight segments 12 of the up ward bending line 11 is approximately 22 degrees.

The blank la also comprises the transversal structure 20 and the bumps 17. The bumps 17 in this embodiment are elongated and transversally oriented.

The bumps 17 and the transversal structures 20 are coloured in order to designate the handle section for ease of use.

The particular shape of the blank la is attributable to the particular shape of the handheld tool which is to be formed out of the blank la. The tool formed out of the blank la of Fig. 3 is supposed to have a broad flat tip making it suitable for such tasks as scooping or shovelling.

The broad flat shape of the vertex allows for forming a cup that is shallow and broad. The broad flat shape may also be helpful to reduce the compression stress at the vertex and also to obtain the desired three-dimensional shape of the functional section of the tool.

The narrowing of the middle lane 31 towards the rear edge 6 may be useful for saving material during mass production of the tool. In particular, due to the tapered shape of the blank la, more blanks la can be accommodated side by side on the same area by placing them in alternating orientation, and hence more blanks can be produced out of a single workpiece.

The weakening of the plateau or central carrying construction by the narrowing of the main lane 31 at the rear edge does not significantly deteriorate the overall stability of the tool, since the main tensions are distributed over the intermediate section 9 and the functional section 8, with a maximum of com pression stress in the region of the vertex 13.

Figs. 4 and 5 show a blank lb. The blank lb is intended for folding to form a handheld tool according to a further embodi ment .

In contrast to the previous embodiments, the blank lb of Fig.

3 has two additional downward folding lines 10a and 10a' in the form of straight lines parallel to the symmetrical axis A of the blank lb. Each of the additional folding lines 10a and 10a' extend from a respective junction point 16 at the vertex 13 to a respective indentation 18 at the rear edge 6 of the blank lb.

The additional folding lines 10a and 10a' act to provide a stronger middle lane 31.

The vertex 13 is slightly narrower as compared to the embodi ment of Fig. 1. The angle between the straight segments 12 of the upward bending line 11 is approximately 31.50 degrees.

In the handle section 7 of the blank lb, similar to the embod iment of Fig. 3, a plurality of elongated transversal bumps 17 are provided with colour marking. Different from the previous embodiments, the functional sec tion 8 has a rounded, slightly elongated or elliptical shape, essentially defined for a specific purpose or intended use of the tool. In the present case, the tool to be formed is a spoon which, due to the sharper shape of the tip 22 and the additional downward folding lines 10 and 10' is suitable for handling harder materials, for example hard ice cream or simi lar .

Figs. 6 and 7 show a blank lc. In use, the blank lc folds to form a handheld tool according to another embodiment.

The blank lc of Fig. 6, in its structural and functional parts, essentially corresponds to the embodiment of Fig. 1.

Different to Fig. 1, the blank lc has a specifically shaped functional section 8 which has an elongated slightly elliptic shape. The reason for this specific shape is that the tool which is to be formed out of this blank lc is a specific type of spoon, similar to a traditional Chinese spoon.

The handle section 7 is narrow as compared to the widest part of the blank lc. The widest part of the blank lc is in the in termediate section 9, closer to the functional section 8.

The angle between the straight segments 12 of the upward bend ing line 11 is approximately 30.5 degrees.

The length of the tool is approximately 130 mm, the width at the widest part and at the rear edge 6 are approximately 40 mm and 35 mm respectively. The handle section 7, the intermediate section 9, and the functional section have lengths of approxi mately 40 mm, 60 mm, and 30 mm respectively. The middle lane 31 has an additional reinforcement 50 shown as a black stripe in the area of the middle lane 31.

The reinforcement 50 is formed by embossing. In a general sense, the reinforcement 50 can also be formed by debossing.

A characteristic feature of the traditional Chinese spoon, be sides its typical shape and proportions, is the shallowness of the spoon, or more precisely of the cup of the spoon. The shallowness of the cup has inter alia an advantage of allowing for rapid cooling of the content of the spoon whilst the spoon is in use.

Different from traditional Chinese spoons, the cup of the spoon made out the blank lc of Fig. 6 does not have a flat bottom. Instead the deepest portion of the cup is defined by the vertex 13.

The narrowness of the handle section results in a smaller ten sile stress along the circumference of the bow 8 and accord ingly in a smaller deformation of the bow from the initial plane geometry. Thus, a shallow form of the cup can be easily achieved .

Figs. 8 and 9 show a blank Id. The blank Id is used for fold ing to form a handheld tool according to further embodiment . This embodiment corresponds essentially to the embodiment of Fig. 6 and represents a blank Id for forming a bigger Chinese spoon. In particular, the functional section 8 and the inter mediate section 9 are wider than in the embodiment of Fig. 6.

The angle between the straight segments 12 and 12' of the up ward bending line 11 is approximately 34.50 degrees. The length of the tool is approximately 130 m, the width at the widest part and at the rear edge 6 is approximately 50 mm and 35 mm, respectively. The handle section 7, the intermedi ate section 9, and the functional section have lengths of ap proximately 40 mm, 60 mm, and 30 mm, respectively.

The middle lane 31 has an additional reinforcement 50 in the form of a reinforcement layer provided along the symmetrical axis A of the blank Id.

For a blank Id that comprises paper, the reinforcement 50 can be provided using blind embossing, which can provide a strong middle lane 31.

Fig. 10 shows a schematic top view of a blank le for folding to form a handheld tool according to another embodiment.

The blank le of Fig. 10 corresponds essentially to the embodi ment of Fig. 1, differing mainly in the front portion of the functional section 8. In particular, the contour line of the front edge 5 shows two recesses 51 arranged axially symmetri cally with respect to the symmetrical axis A of the blank le in such a way that three teeth in the functional section 8 are formed. The tip 22 of the bow 32 is at the same time the tip of the middle tooth of tine.

After forming the tool from the blank le, these teeth can serve as fork tines and the tool itself can be used as a fork.

Fig. 11 shows a schematic top view of a blank If for folding to form a handheld tool according to another embodiment.

The blank If of Fig. 11 corresponds essentially to the embodi ment of Fig. 3, differing mainly in the shape of the front portion of the functional section 8 of the blank If. In par ticular, the contour line of the front edge 5 shows two re cesses 51 arranged symmetrically with respect to the symmet rical axis A of the blank If in such a way that three teeth in the functional section 8 are formed. The tip 22 of the bow 32 is at the same time the tip of the middle tooth of tine. Simi lar to the embodiment of Fig. 3, the tip 22 is flat and ac cordingly the middle tooth of the functional section 8 is flat as well .

Forming a handheld tool out of the blank If shown in Fig. 11 results in a tool with broad teeth, which can be used as both as a fork and as a spoon, and could be used for instance for eating cake, ice cream, spaghetti, or similar.

Fig. 12 shows a schematic top view of a blank lg for folding to form a handheld tool according to a further embodiment.

The blank lg of Fig. 12 corresponds essentially to the embodi ment of Fig. 4, differing mainly in the shape of the front portion of the functional section 8 of the blank lg. In par ticular, similar to previous two embodiments, the contour line of the front edge 5 shows two recesses 51 arranged symmetri cally with respect to the symmetrical axis A of the blank lg in such a way that three teeth in the functional section 8 are formed. The tip 22 of the bow 32 is at the same time the tip of the middle tooth of tine. In contrast to the previous two embodiments, the three teeth are not blunted. Consequently, forming a handheld tool out of the blank lg shown in Fig. 12 results in a fork with sharp teeth. In particular, due to the sharp teeth and due to the reinforcement structure in the mid dle lane, the fork can be used for handling relatively hard matter, like flower soil, or harder meal, like hard ice cream, or similar. Fig. 13 shows a schematic top view of a blank lh for folding to form a handheld tool according to another embodiment.

In the functional section 8 of the blank lh, three teeth simi lar to the teeth of the embodiment of Fig. 10 are formed.

Characteristic for the embodiment of Fig. 13 is a broader mid dle lane 31 and a flat vertex 13, especially as compared with the embodiment of Fig. 10. Further, the angle between the straight segments 12 of the upward bending line 11 is approxi mately 35.25 degrees. This is relatively wide angle, resulting in a shorter intermediate section 9 and a longer handle sec tion 7. Besides, the middle lane 31 is provided with a rein forcement 50 which is indicated by the solid black colour of the middle lane 31.

Forming a tool out of the blank lh of Fig. 13 results in a fork of specific geometry which can be used for handling par ticularly hard matter. Indeed, the reinforcement 50 of the middle lane 31 and the longer handle section 7 allows for the application of particularly large force on the tool without causing damage to the tool.

Fig. 14 shows a schematic top view of a blank li for folding to form a handheld tool according to a further embodiment.

This embodiment corresponds essentially to the embodiment of Fig. 6 showing a blank li for forming a spoon similar to a Chinese spoon. In the front part of the functional section 8, however, the blank li of Fig. 14 has two recesses 51 forming three teeth. Thus, by folding the blank li, a tool can be formed which essentially resembles a Chinese spoon, but which can be used as a fork. Figs. 15 and 16 show a blank lj, which is intended for folding to form a handheld tool according to another embodiment.

Different to the previous embodiments, in addition to the side wings 30 extending over the handle section 7 and over the in termediate section 9 on both sides of the symmetrical axis A, the blank lj shown in Fig. 15 comprises two corner wings 60 or corner wings at two handle section corners adjacent to the rear edge 6 of the blank lj . The handle wings 60 are demar cated from respective side wings 30 by two handle bending lines 61. The handle bending lines 61 extend from the rear edge 6 of the blank lj to the respective endpoint 21, 21' at the respective side edge 4, 4' of the blank 1j . The handle bending lines 61 facilitate bending of the handle wings 60, in particular, bending down from the figure plane away from the viewer, as indicated by the downward movement symbols 33.

The basic material of the blank lj of Fig. 15 is silicone.

With silicone as its basic material, the blank lj can be formed into a durable silicone-based tool, such as a reliable silicone-based kitchen utensil.

As seen in Fig. 16, the blank lj also comprises a middle lane 31 with a reinforcement in the form of an embedded metal sheet 31a which is shown as a dark portion of blank lj along the symmetrical axis A. This extends along the symmetrical axis A from the vertex 13 towards the rear edge 6 and terminates in the handle section 7 before reaching the rear edge 6. In use, the metal sheet 31a enables the middle lane 31 to be stiff and stable. In other words, the middle lane 31 can bear more weight or stress. Due to this configuration of the middle lane 31 and the handle wings 60, a portion of the handle section between the handle wings 60 at the rear edge 6 can remain unfolded after the tool is formed. Thus, a comfortable handle with a kind of "volume- effect" can be shaped.

Further, the embodiment of Fig. 15 comprises a reinforcement in the handle section 7, in particular in the handle wings 60. This is shown as dark triangles in the handle wings 60. In this embodiment, the reinforcement of the handle wings com prises extrusion moulded silicone. In some embodiments, the reinforcement may comprise one or more metal layers embedded in the blank lj in the region of the middle lane 31 and in the handle wings 60.

In other embodiments, the reinforcement may comprise surface layers laminated on the blank 1j , particularly at locations which are exposed to increased strain, like the middle lane 31, especially in the vicinity of the vertex 13 or the handle section, which is grasped by the user while using the tool.

The front edge 5 is straight such that the tip 22 of the front portion is essentially flat.

The length of the tool is approximately 160 mm, and the width approximately 40 mm. The handle section 7, the intermediate section 9, and the functional section have lengths of approxi mately 50 mm, 80 mm, and 40, respectively.

The angle between the straight segments 12 of the upward bend ing line 11 is approximately 25.90 degrees. The dimensions, especially the length of the intermediate sec tion 9 and the functional section 8, as well as the angle be tween the straight segments 12 of the upward bending lines 11 may vary significantly depending on the purpose of the tool.

The length of the tool is approximately 160 mm, and the width approximately 40 mm. The handle section 7, the intermediate section 9, and the functional section have respective lengths of approximately 50 mm, 80 mm, and 30 mm. The width of the middle lane 31 is approximately 4 mm.

The blank lj also comprises grip structures or grippers. The grippers in this embodiment are provided in the form of elon gated structures or stripes of protruded silicone.

In some embodiments, the grippers with coloured patterns are provided in the handle section 7. The colour pattern and the geometry of the grippers may vary, depending on the specific design of tool.

Fig. 17 shows a cross-sectional view of a variant of the blank of Fig. 15. Fig. 17 show a blank lja that comprises silicone material. The blank lja includes a middle lane 31, which com prises an enlarged body for reinforcing the middle lane 31.

Fig. 18 shows a cross-sectional view of another variant of the blank of Fig. 15. Fig. 18 shows a blank ljb. The blank ljb in cludes a middle lane 31, which comprises a metal sheet 31b that is attached to an outer surface of a body of the middle lane 31 for reinforcing the middle lane 31.

Fig. 19 shows a schematic top view of a blank lk for folding to form a handheld tool according to a further embodiment. The blank lk shown in Fig. 19 corresponds in its essential features to the embodiment of Fig. 15, and shows some differ ences as well, especially in the design of the handle section 7 and of the functional section. The bumps 17 in the handle section 7 are round or dot-shaped.

The front edge 5 has a circular shape such the tip 22 of the front portion or the function section 8 is essentially round.

The length of the tool is approximately 110 mm, and the width approximately 40 mm. The handle section 7, the intermediate section 9, and the functional section have lengths of approxi mately 50 mm, 30 mm, and 30 mm, respectively. The width of the middle lane 31 is approximately 2 mm.

The angle between the straight segments 12 of the upward bend ing line 11 is approximately 66.00 degrees.

Due to its dimensions and shape, the blank lk in the folded state results in a tool which is specifically suitable for us ing as a small scoop for ice-cream or rice, or as a ladle by bending the segment 8 in the other direction.

In some embodiments, the blank lk comprises magnetized metal plates for ease of use.

Fig. 20 shows a schematic top view of a blank 11 for folding to form a handheld tool according to another embodiment.

The embodiment of Fig. 20 differs from the embodiment of Fig. 19 by the lengthwise orientation of the bumps in the handle section 7 as well as in the dimensions . The length of the tool is approximately 140 m, and the width approximately 40 mm. The handle section 7, the intermediate section 9, and the functional section have lengths of approxi mately 50 mm, 60 mm, and 30 mm, respectively. The width of the middle lane 31 is approximately 4 mm.

The angle between the straight segments 12 of the upward bend ing line 11 is approximately 34.10 degrees.

Such dimensions and shape of the blank 11 make the blank 11 suitable for forming a tool which can be used as a ladle, scoop, spatula, funnel, spade or shovel.

Fig. 21 shows a schematic top view of a blank lm for folding to form a handheld tool according to another embodiment.

This embodiment corresponds to the embodiment of Fig. 20 and differs mainly in the shape of the functional section 8. In particular, the tip 22 of the functional section 8 is flat such that the blank lm has essentially the shape of a rectan gle with rounded corners .

A tool formed out of such a blank lm is particularly suitable for usage as a spatula, scraper, funnel, spade or shovel.

Fig. 22 shows a schematic top view of a blank In for folding to form a handheld tool according to a further embodiment.

The blank In of Fig. 22 corresponds essentially to the embodi ment of Fig. 19 and differs mainly in the shape of the func tional section 8 and in the proportions. In particular, the functional section 8 is longer and the tip 22 of the func- tional section 8 has a rounded elliptic shape. In the func tional section 8, a plurality of holes 70 are provided. One of the holes is provided at the tip of the vertex 13.

The middle lane 31 with a reinforcement extends along the sym metrical axis A of the blank In over the intermediate section 9 and the handle section 7 without reaching the vertex 13 and the rear edge 6.

The length of the tool is approximately 140 mm, and the width approximately 40 mm. The handle section 7, the intermediate section 9, and the functional section have lengths of approxi mately 50 mm, 50 mm, and 40 mm, respectively. The width of the middle lane 31 is approximately 2 mm.

The angle between the straight segments 12 of the upward bend ing line 11 is approximately 41 degrees.

The hole 70 at the vertex can serve for stress release and can facilitate the forming of the tool.

The particular shape and the holes 70 make the blank In par ticularly suitable for forming tools which can be used as a strainer, scoop or similar.

The plurality of holes 70 can be die-cut in the blank In. The holes are essentially round and have a diameter of approxi mately 1.5 mm.

The diameter of the holes can be varied, in particular in the range from 1 mm up to 3 mm, depending on the purpose of the tool . In an embodiment, no holes in the functional section 8 and at the vertex 13 are provided. In the embodiment without holes, the middle lane and the reinforcement of the middle lane 31 can be extended to the vertex 13. Tools shaped out of such em bodiments can be used for example as a spatula, scoop or la dle .

Fig. 23 shows schematically a possible panel arrangement for producing a blank according an embodiment .

In the upper part of Fig. 23, a row of blanks according to the embodiment of Fig. 3 is shown. The blanks in the upper row are arranged in alternating orientation. In particular, every sec ond blank is oriented with its functional part up and with its handle part down.

In the lower part of Fig. 23 a row of rectangular blanks with the same lateral dimensions as the upper blanks is shown.

As can be seen from Fig. 23, due to the tapered shape of the blanks in the upper row, more blanks can be placed on the same area .

Thus, the tapered shape of blanks, along with the design's technical importance discussed above, has an advantage from the manufacturing point of view. In particular, in the bulk production of the blanks worksheet material and production costs can be saved by alternating the orientation of adjacent blanks in the worksheet. Thus, due to the tapered shape of the blank, a saving of more than 10 % in worksheet material in the bulk production can easily be achieved.

In this example, a material saving of 11.25 % has been achieved . Even in bulk production with smaller panels, i.e. in the case of smaller workpieces, the alternating orientation of the blanks can still lead to considerable savings .

In some embodiments of the manufacturing process, two blanks are produced and die-cut out of a single workpiece or work sheet. Due to the tapered shape of the blank, up to approxi mately 6 % of material savings can be achieved, depending on the specific design of the blank.

Figs. 24 to 37 show different embodiments of the blank in its initial and in its folded state from different views .

In the central upper part of Figs. 24 to 33 a top view of a blank according to a respective embodiment in an unfolded or initial state is shown.

On the left-hand side of the upper row a top view of the re spective tool is shown. On the right-hand side of the upper row a bottom view of the tool is shown.

In the lower part of the Figs. 24 to 37, perspective views of the formed tools under different view angles are shown.

The embodiments shown in Figs. 24 to 33 correspond to the em bodiments shown in Figs. 1 to 14 above.

The embodiments shown in Figs. 34 to 37 correspond essentially to the embodiments shown in Figs. 15 to 22 but also include some important modifications.

In particular, different to the embodiment of Figs. 11 to 15, the embodiments of Figs, 27 to 30 comprise a reinforcement. In a case wherein the embodiment is produced using paper, the re inforcement can be provided using blind emboss. In a case wherein the embodiment is produced using silicon material, the reinforcement can be provided using extrusion-moulded sili cone. This area with the reinforcement is shown in the figures as a dark in particular triangular area extending from the vertex to the handle section.

In some embodiments, an extrusion-moulded rubber is used, as a reinforcement .

Further, in the embodiments of Figs. 34 to 37 a middle lane in the form of a stripe extending along the symmetrical axis A is missing. Instead, a middle lane or middle channel is created together with the folding of the side wings. Similar to the middle lane, the middle channel or tube has the same support ing effect and contributes to the robustness of the tool.

It is also worth mentioning that the tools formed out of the blanks according the embodiments can be in general easily mod ified or transformed by changing the bending direction of the functional part of the blank. In particular, an energetically favourable stable configuration can also be achieved when the front portion of the functional section is bent in the same direction with respect to the plane of the middle lane as the side wings.

As better seen in Figs. 89 to 92, the sheet includes a major top surface 2 and a major bottom surface 3 being provided op posite the major top surface 2, a first side edge 4 and a sec ond side edge 4' being provided opposite the first side edge 4, as well as a front edge 5 and a rear edge 6 being provided opposite the front edge 5. A first end part of the first side edge 4 is placed next to a first end part of the rear edge 6. A second end part of the rear edge 6 is placed next to a first end part of the second side edge 4' . A second end part of the second side edge 4' is placed next to a first end part of the front edge 5. A second end part of the front edge 5 is placed next to a second end part of the second side edge 4.

Referring to Fig. 89, the sheet includes a first sheet portion 9-lp together with a second sheet portion 9-2p, and a bending cum connection strip lip. The first sheet portion 9-lp is in tegrally connected to the bending cum connection strip lip, which is integrally connected to the second sheet portion 9- 2p. As seen in Figs. 90 and 91, a plane of the first sheet portion 9-lp is also separated from a plane of the second sheet portion 9-2p by a predetermined distance d. In other words, the second sheet portion 9-2p is elevated or raised with respect to the first sheet portion 9-lp.

The sheet portion 9-lp and 9-2p refer to a large thin portion, which can be flat or bended.

Referring to Fig. 89, the bending cum connection strip lip in cludes two essentially straight strip segments 12p and 12p' and an essentially circular strip segment 13p. The straight strip segments 12p and 12p' are connected to the circular strip segment 13p such that the bending cum connection strip lip is symmetrical around the axis A. The circular strip seg ment 13p is also called a vertex.

In detail, a first end of the straight strip segment 12p is placed next to the first side edge 4. The straight strip seg ment 12p extends from the side edge 4 towards the symmetrical axis A. The straight strip segment 12p is placed at an acute angle with respect to the side edge 4. A second end of the straight strip segment 12p is placed next to a first end of the circular strip segment 13p. The second end of the straight strip segment 12p and the first end of the circular strip seg ment 13p are placed at a junction point 16.

Similarly, a first end of the straight strip segment 12p' is placed next to the second side edge 4' . The straight strip segment 12p' extends from the side edge 4' towards the symmet rical axis A. The straight strip segment 12p' is placed at an acute angle with respect to the side edge 4' . A second end of the straight strip segment 12p' is placed next to a second end of the circular strip segment 13p. A second end of the straight strip segment 12p' and the second end of the circular strip segment 13 are placed at a junction point 16' .

Referring to the second sheet portion 9-2p, it includes bend ing lines lOp and IOr' . The bending lines lOp and 10p' extend between the rear edge 6 of the moulded blank lp and the circu lar strip segment 13p. The bending lines lOp and 10p' are placed on the top surface 2.

The bending line lOp comprises two straight bending line seg ments 14pl and 14p2 together with a curved bending line seg ment 15p. A first end part of the straight bending line seg ment 14pl is placed next to the rear edge 6. A second end part of the straight bending line segment 14pl is placed next to a first end part of the curved bending line segment 15p. A sec ond end part of the curved bending line segment 15p is placed next to the junction point 16. The second end part of the curved bending line segment 15p is also placed next to a first end part of the straight bending line segment 14p2. A second end part of the straight bending line segment 14p2 is placed next to the rear edge 6. Similarly, the bending line 10p' comprises two straight bend ing line segment 14pl' and 14p2' and a curved bending line segment 15p' . A first end part of the straight bending line segment 14pl' is placed next to the rear edge 6. A second end part of the straight bending line segment 14pl' is placed next to a first end part of the curved bending line segment 15p' . A second end part of the curved bending line segment 15p' is placed next to the junction point 16' . The second end part of the curved bending line segment 15p' is also placed next to a first end part of the straight bending line segment 14p2' . A second end part of the straight bending line segment 14p2' is placed next to the rear edge 6.

The straight bending line segments 14pl and 14p2 and the straight bending line segments 14pl' and 14p2' extend longitu dinally with respect to the blank lp.

The straight bending line segments 14pl and 14p2 are placed on a first side of the symmetrical axis A while the straight bending line segments 14pl' and 14p2' are placed on a second side of the symmetrical axis A, which is opposite the first side. The straight bending line segments 14pl and 14p2 and the straight bending line segments 14pl' and 14p2' are placed closed to and parallel to the symmetrical axis A such that the straight bending line segments 14p2 and 14p2' and the curved bending line segments 15p and 15p' and the circular strip seg ment 13p enclose a stripe or channel that extends from the rear edge 6 to the circular strip segment 13p.

The channel has an essentially constant width over its whole length, except in the vertex region, in which the curved bend ing line segments 15p and 15p' separates further away from the symmetrical axis A. In use, the shape of the moulded blank lp can change under pressure. In other words, the moulded blank lp is flexible. Without external pressure or force, specifically external com pressive forces, the blank lp has a shape as shown in Figs. 89 to 92. This shape can change when a predetermined compressive force is applied to the moulded blank lp.

The bending line 10p' includes a groove or channel, wherein the groove is connected to two opposing parts . One part can bend or rotate around the groove, with respect to the other part .

A connection or joint between the first sheet portion 9-lp and the bending cum connection strip lip acts as a bending line. The first sheet portion 9-lp can bend or rotate around the bending line, with respect to the bending cum connection strip lip .

Similarly, a connection or joint between the second sheet por tion 9-2p and the bending cum connection strip lip also acts as a bending line. The second portion 9-2p can bend or rotate around the bending line, with respect to the bending cum con nection strip lip.

A method producing the blank lp using pulp moulding is de scribed below. The pulp moulding is also called heat pressing or thermoforming of fibre.

A fine wire mesh is initially provided. The wire mesh, which acts as a mould, is connected a chamber with a vacuum pump, wherein the wire mesh is suspended above a liquid return pool. The wire mesh has a shape of an upper or exposed surface of the blank lp, wherein the surface includes bending lines. After this, a food-safe wet fibrous slurry is sprayed from be low onto the wire mesh. The fibrous slurry is produced using food-safe fibers.

The vacuum pump then draws the slurry tightly against the wire mesh, wherein fibers of the slurry fills all or most gaps and spaces of the wire mesh while also drawing water of the slurry through the wire mesh into the vacuum chamber. When airflow through the wire mesh has been sufficiently blocked by the fi bers, excess slurry falls into the return pool for recycling.

The wire mesh together with the fibers, which are shaped by the wire mesh, later moves to an area for drying the fibers, wherein the dried fibers form the blank lp.

Following this, the wire mesh is separated from the dried blank lp.

In one implementation, a blank produced by pulp moulding has a thickness of at least 1 millimeter (mm) .

The pulp moulding can elevate a bowl section and a handle sec tion of the blank whilst elevating or lowering bending lines of the blank according to design-engineered customized moulds used to produce the blank. These elevated parts and the low ered parts enable ease of use. In other words, these parts al low the blank to be folded easily. A user can simply pinch the blank to fold the blank to form a desired tool, such as a fork or spoon.

The blank produced by pulp moulding can also be branded or in corporated with a description through various methods, such as precision emboss and deboss . This blank can remain essentially flat when packed due to flexibility and thinness of material used to produce the blank .

The pulp moulding allows production of thin walled products or blanks, which are often be well defined and have smooth sur faces .

In a further implementation, the blank is produced using ther moforming. While a mould forms a blank or product, the mould also produces heat to press and densities the moulded product. The product is later ejected from the heated mould in its fin ished state as opposed to being dried in a heated oven. Such product often has the appearance of plastic material while the production process allows accurate formation of the product.

The blank is often designed, wherein the bending lines are placed on the same side of the blank. This allows the bending lines (and any crease and preforation) to be produced using the same mould. Furthuremore, the placement of the bending lines is precise, since one, and not two moulds, is used to produce these bending lines .

In a generic sense, the blank can be made using various meth odologies including moulding and/or injection moulding of dif ferent materials. Examples of this include FDA approved food grade (recyclable) silicone/rubber.

The blank can also be produced from different other materials, such as silicone, and it can have various thickness depending on material original strength and purpose of tool being pro duced by the blank. In another embodiment, a sheet of paper is provided. After this, a mould is used to press the sheet to form the first sheet portion 9-lp together with the elevated second sheet portion 9-2p of the blank lp. Following this, the bending line lOp and 10p' are provided on the paper using scoring to form the finished blank lp. Heat can also be applied to form the elevated second sheet portion 9-2p.

The blank lp provides a benefit in that the separation of plane of the first sheet portion 9-lp from the plane of the second sheet portion 9-2p allows for easier folding of the blank lp to form the spoon.

A user can just bend the bank lp to form a spoon in one move ment. The user presses the side edges 4 and 4' toward each other. The bending cum connection strip lip then allows and eases the first sheet portion 9-lp to bend or rotate around the bending line or joint, which is provided between the first sheet portion 9-lp and the bending cum connection strip lip. Similarly, the bending cum connection strip lip also allows and facilitates the second sheet portion 9-2p to bend or ro tate around the bending line or joint, which is provided be tween the second portion 9-2p and the bending cum connection strip lip.

In summary, the blank includes a first flat part, a second flat part, and a connection part. The first flat part is con nected to the connection part, which is connected to the sec ond flat part such that the first flat part is elevated with respect to the second flat part. The elevation or separation between the two flat parts can be formed using different methods. Each method can include dif ferent process steps, such as application of pressure, appli cation of vacuum or suction, and/or application of heat.

Referring to the blank, height of the elevation can be se lected according to material of the blank. In general, the height should be more than a thickness of the blank.

The blank can be produced from paper material or metal mate rial or other food-safe material.

In use, the elevated part is often selected to serve as a han dle/bridge section.

The first straight bending line segment 724 of the diagonal- scored lines forms an angle of about 30 degrees with the first side edge 683S1.

Similarly, the second straight bending line segment 726 is placed on the bottom surface of the sheet 683 and it extends from another end of the short-bending line segment 710S to an other end of the second-long edge 704C of the first handle portion 704, which is placed near to the second side edge 683S2. The second straight bending line segment 726 of the diagonal- scored lines forms an angle of about 30 degrees with the sec ond side edge 683S2.

Referring to the outer longitudinal-scored lines, they include a first longitudinal straight bending line 730L1 and a second longitudinal straight bending line 730L2. The first longitudi nal straight bending line 730L1 is placed parallel to the sec ond longitudinal straight bending line 730L2.

The first longitudinal straight bending line 730L1 extends from one end of the first straight bending line segment 724 to the edge 706C of the second handle portion 706. The one end of the first straight bending line segment 724 is placed near to the spoon rest groove 735G1.

Similarly, the second longitudinal straight bending line 730L2 extends from one end of the second straight bending line seg ment 726 to the edge 706C of the second handle portion 706.

The one end of the second straight bending line segment 726 is placed near to the spoon rest groove 735G2.

In a special embodiment, the scored lines 685, such as the straight bending line segments 724 and 726, as well as the long-bending line segments 710L1 and 710L2 include sectional perforated lines to aid bending of the blank 681, especially when the blank 681 is thick or stiff. The sectional perforated line includes either through small slits, holes, or blind holes .

In one implementation, the think blank 681 has a paper mate rial of more than 400 GSM. Functionally, the blank 681 is intended for folding manually to form a spoon.

The bowl portion 702 is intended for folding to form a con tainer of the spoon.

The first handle portion 704 and the second handle portion 706 are intended for folding to form a handle of the spoon.

The scored lines 685 allow parts of the blank 681 to bend to ward different predetermined directions for forming the spoon.

In detail, the first straight bending line segment 724, the short bending line segment 710S, the second straight bending line segment 726 allow the respective parts of the blank 681 to bend to form the container of the spoon.

The first longitudinal straight bending line 730L1, the second longitudinal straight bending line 730L2, the first long-bend ing line segment 710L1, and the second long-bending line seg ment 710L2 allow the respective parts of the blank 681 to bend to form the handle of the spoon.

The first straight bending line segment 724, the short bending line segment 710S, and the second straight bending line seg ment 726 have curved parts, which are adapted such that these segments 724, 710S, and 726 form a smooth line which does not cut a user of the spoon. In other words, the smooth line does not have sharp corners, which can cut the user.

The first long-bending line segment 710L1 is placed at a small angle to the second long-bending line segment 710L2 for strengthening the handle. Put differently, this arrangement of the first long-bending line segment 710L1 and the second long- bending line segment 710L2 prevents the handle from bending.

The handle locking slits 740S1 and 740S2 are used for inter locking with each other such that the handle is formed in a firm or secured manner. In other words, the handle locking slits 740S1 and 740S2 act as a locking mechanism.

The spoon rest grooves 735G1 and 735G2 are intended for plac ing on a rim of a cup or bowl such that the spoon hangs on the cup or bowl. The spoon rest grooves 735G1 and 735G2 allow the rim to support the spoon.

In short, the blank includes a container portion, a handle portion, and two cut-off parts being positioned between the container portion and the handle portion.

The cut-off parts act as spoon rest grooves. The two cut-off parts also allow the blank to fold easily along a longitudinal axis of the blank. In other words, the cut-off parts enable the respective parts of the blank to bend easily about the first longitudinal straight bending line 730L1 and the second longitudinal straight bending line 730L2.

The handle portion includes a locking mechanism. The locking mechanism comprises the handle locking slits . The handle por tion is intended for folding to form a handle of the handheld tool while the locking mechanism serves to lock folded parts of the handle portion such that the folded parts are fixed to one another.

The perforated bending line 724 allows easy bending of parts of the blank 981-1 which are attached to or are placed on the bending line 724. These parts are bent when the blank 981-1 is folded to form a spoon. Similarly, the perforated bending line 726, and the perforated bending lines 730L1 and 730L2 allow easy bending of the respective parts of the blank 981-1 to form the spoon.

The ease of bending is useful, especially when the blank 981-1 is thick, wherein the thickness makes the blank 981-1 stiff and difficult to bend.

Furthermore, the perforation allows for further cost saving.

As an example, bottom-scoring, the perforation, and die-cut can be achieved in one process with one tool. Any top-scoring can be replaced by the perforated lines and by the bottom scoring. This then enable saving of production cost as the only step is needed to provide the bending lines on the blank for forming spine and apex segment of the blank, which is re sistant to tearing.

In short, the perforation of the blank 981-1, the scoring of the blank 981-1, and the die-cut to form the spoon blank with bending lines can be done using the same mould and at the same process step. This means the perforation can be done with min imal or no additional cost. This is useful for allowing the blank 981-1 to be produced a low cost.

In summary, the blank has formation, strength and durability because it includes a few important lines, angles, curvatures and especially craniovertebral-vertebrae like structure. These features provide functions that are triggered in required pro portions and are corelated with one another to produce the re quired dynamics in unity.

The blank has a bowl section, a neck section and a handle sec tion, which are similar to the supportive structure of human beings, namely the vertebral column or the spine of which the significant parts include the atlas and axis combination, and together, they form a 'craniovertebral vertebrae' part of the blank .

When the blank is adapted for forming a spoon, the meeting of a blunted vertex at a base of the spoon with an 'anterior arch of atlas' part creates a semi-convex edge on a 'cranioverte bral vertebra' part of a neck section of the spoon. In use, this acts to direct and distribute forces and pressure as well as to increase stability for forming a 'spinous process'

(spine) part and an 'articular pillars' part of a handle sec tion of the spoon through to a neck section of spoon.

A mere pinch on sides of a shoulder of the handle section ef fects or forms a bowl section of the spoon to rise in opposite direction on one surface, interchangeably to form a scoop sec tion on the other surface.

The significant feature in the blank is the pair of curved portions ( 'arch' on the bowl section) at the end of the pair of bending lines of the handle section. The vertex of the up ward bending line and the curved portions of downward bending line form a pair of circular curvatures ( 'arch' ) on the sides and a semi-convex edge on the neck section of the spoon.

In short, the atlas and axis combination of the blank acts as the 'craniovertebral vertebrae' that produces a powerful 'semi-convex edge' with an 'anterior arch of atlas' part at the vertex of the upward bending line at the central of base of the spoon.

The pair of circular curvatures and the 'semi-convex edge' on the neck section elevate to form a sturdy structure for the base of bowl section.

The 'semi-convex edge' of the pair of circular curvatures en sures balanced distribution of forces, strength and pressure on the base of bowl section as well as the neck section of the spoon. This 'semi-convex edge' of the atlas and axis is a critical attribute to the strong base of spoon and for the neck section and the handle section (akin to our skull and neck, the atlas and axis being pivotal in holding the skull as well as enabling flexibility of movement) .

Equally significant, the end points ( 'transverse process' ) of these pair of curved portions ('arch') divert the immense pressure impact away from a head-on meeting point on vertex as compared to straight line endpoints. The diversion endpoints ( 'transverse process' ) of the curved portions (arch' ) prevent tearing at meeting points on vertex that straight-line end points cannot withstand.

The curved portions (arch' ) at the end of the pair of bending lines are in a pair. Without them, the 'semi-convex edge' can not form, thus results to a weak spoon.

The blank' s continuous directional bending lines with circular curvatures and 'semi-convex edge' are especially significant in preventing paper spoon from being easily 'disfigured' and/or deformed by users. Without precise directional lines, it is difficult to control formation of the paper spoon be cause apart from difficulty in bending thick stock, paper grains are never truly straight angle (180°) nor right angle (90° ) .

The 'craniovertebral vertebrae' part in the blank embodies a 'spinous process' part of handle section created with a pair of straight bending lines in the middle of the 'articular pil lars' , formed by two straight bending lines beside and paral lel to the 'spinous process' straight lines.

Similar to human vertebral column, the blank' s strength and durability are provided with one 'spine' , reinforced by two 'pillars/columns' with four straight bending lines from the 'semi-convex edge' at the neck section of spoon to the edge of handle section of spoon to enable a strong and sturdy user- friendly handheld tool.

The other significant feature in the blank is the wide vertex where forces meet upon formation. Regarding the circular or round-cornered trapezoid vertex, the meeting of opposing force at this blunted 'anterior arch of atlas' wide vertex distrib utes energy/strength/pressure for and from the 'semi-convex edge' of the neck section and base of the bowl section.

The meticulously structured 'anterior arch of atlas' vertex transforms the central base of the bowl section together with the 'semi-convex edge' at the neck section of spoon into the strongest form to sturdily contain, carry and/or support vol ume/weighted content multiple times beyond its own weight (akin to human's ability to carry tremendous weight and/or va riety of content on our head) . The blank serves as tools that are multiform and multifunc tion .

Referring to the bowl section of the blank, the bowl section is formed by a kind of anterior arch of atlas with wide blunted vertex, which can be circular or round-cornered trape zoid. The bowl section has enough depth, thereby allowing it to provide multi-functions to act as spoon, scoop, funnel or spreader. The depth also enables the bowl section to hold var ious contents, as what a spoon can do, including liquid or semi-liquid foods, and very small or powdery solid items.

Referring to the neck section of the blank, it has no hinge.

It can serve as child proof eating utensils enabling spoonful of content to be consumed with ease. It is structurally sturdy and well supported from the handle section to the neck section and to the bowl section. It is user-friendly.

The neck section structurally prevents backflowing on its spoon side. The blank has circular curvature on its anterior arch of atlas vertex providing more than 2 distinct uses on each side of the tool. On one side, it can be a spoon or ladle holding liquids without possibility of leak/backward flow. On the other side, it can be a scoop or a funnel allowing liquids to flow through.

The neck section provides stability and ease of carrying mul titude of content and volume multiple times its own weight. Upon elevation of parts of the blank, the 'craniovertebral vertebrae' part that is created by the pair of curved portions ( 'arch' ) equally distribute forces, equalizes burden and pres sure thus form a stable neck section and base of spoon. This is a crucial point in its ability to carry with ease, content variations with volume multiple times heavier than itself. Referring to the handle section of the blank, it is strong as the forces on the handle section are connected and directed from its 'craniovertebral vertebrae' part. A pair of downward bending lines forming the 'spinous process' part in the middle is further strengthened by 'articular pillars' formed by an other pair of downward bending lines. In turn, they create a semi 3-tier slopes on the handle section upon formation.

The 3-tier slopes on top surface of the handle section create a formidable strong tri-spine to the handle section. This strong 'tri-spine' close-top handle section produces a practi cal, sturdy spoon that is comfortable to hold. The 3-tier slopes on spoon handle section provide users the ease of con trol. The sturdy handle section is further available in a va riety of friction studs or grooves for greater grip to suit usage .

It should be noted that the term "scoring" can be replaced with the term "creasing" when producing the blank using paper.

The paper can have a weight of about 250 grams per square me ter (gsm) to about 500 gsm.
