Description:
"BAKING MOULD FOR FOODSTUFF, PARTICULARLY FOR

CONFECTIONERIES"

D E S C R I P T I O N

The present invention refers to a mould for baking foodstuff, particularly confectioneries. The present invention particularly refers to moulds for baking confectioneries of medium/large size such as panettonis, pies and similar.

Baking moulds for confectioneries, for example panettonis, are known. The known moulds comprise a base, usually of a circular shape, and a lateral wall. The base and the lateral wall are separately manufactured and are successively assembled. The step of assembling the base and the lateral wall of the mould has the object of making them integrally to each other in order to form a cavity suitable for housing the dough to be baked. The step of assembling the lateral wall and the base usually provides a step of pasting a portion of the lateral wall to the base; such pasting step is perimetrally made with respect to the base and at the lower portion of the base. The lateral wall, in order to be pasted to the base of the mould, is usually at least partially folded at the lower perimetral portion of the base. The portion of the lateral wall pasted to the lower portion of the base usually takes the shape of a circular crown perimetrally placed with respect to the base of the mould.

However, the known moulds have some drawbacks, such as the duration and complexity of the process for manufacturing the mould. Further drawbacks can occur when the paste is not correctly spread at the mould surfaces to be pasted which, being placed at the perimetral lower portion of the base of the mould, must be suitably pasted for ensuring a correct operation of the same baking mould. For example, when the base is not correctly pasted to the lateral wall of the mould, the dough, which upon its introduction into the mould is usually at a liquid state, could leak out of the mould itself. A suboptimal pasting of the surfaces of the mould at the lower portion of the base could further create problems during the handling and/or transport of the foodstuff in a step after its baking. Further problems can occur when the paste is not homogeneously spread at the mould surfaces to be pasted. For example, a disuniform distribution of the paste can negatively affect the heat transmission at the lower perimetral portion of the mould base, and could cause problems of inhomogeneous baking the foodstuff inside the mould. A further drawback consists of the fact that the conventional moulds cannot be reused because they are cut and/or torn during the operations preliminary to the consumption of the foodstuff received therein, so that it is prevented a subsequent use thereof.

A main object of the present invention consists of solving one or more of the problems of the prior art.

An object of the present invention consists of simplifying the process for manufacturing a mould for baking foodstuff, particularly confectioneries. A further object of the present invention consists of providing a baking mould for foodstuff being simple and economic to be manufactured. It is an object of the present invention to propose a mould provided with a greater stiffness at the lateral wall.

Further, it is an object of the present invention to provide a mould capable of making more homogeneous the baking of the foodstuff, particularly at the base of the mould .

With reference to the figures, 1 generally indicates a baking mould for foodstuff, particularly for medium- large sized confectioneries such as panettonis, pies and similar. The mould 1 is of the one-piece type and can be made of paper material, particularly by die-cutting a sheet of paper material, which can consists of one or more layers.

The mould 1 comprises a bottom wall 2 and a lateral wall 3, which, being of a one-piece type, are bonded without interruption.

The bottom wall 2 represents the base portion of the mould 1 and can be characterized by a polygonal perimeter 4, as illustrated for example in Figure 3. The polygonal perimeter 4 can comprise one or more sides 5; particularly the polygonal perimeter 4 comprises a number of sides 5 comprised between 6 and 14. Preferably, the number of sides 5 of the polygonal perimeter 4 is comprised between 8 and 12; particularly the number of sides 5 can be equal to 10.

The polygonal perimeter 4 of the bottom wall 2 further defines the region at which the bottom wall 2 is bonded without interruption to the lateral wall 3.

One or more sides 5 forming the perimeter of the bottom wall 2 can develop for a length L; particularly each side 5 develops for the same length L.

Preferably, the geometrical shape characterizing the polygonal perimeter 4 of the bottom wall 2 of the mould 1 can be formed by a regular type polygon. In Figure 3 and in Figure 6 a mould 1 having a bottom wall 2 characterized by a regular polygonal perimeter 4 is shown, wherein the regular polygon is a decagon.

The polygonal perimeter 4 can have a distance A between two non consecutive vertexes, which can be defined by a diagonal joining the two non consecutive vertexes. Preferably, the two vertexes between which the distance A can be calculated, can be opposite, particularly opposite to the centroid of the polygon defining the polygonal perimeter 4 of the bottom wall 2. Particularly, with reference to two opposite vertexes of the polygonal perimeter 4, the mould 1 can comprise a maximum distance A not less than 10 cm or 15 cm or 18 cm.

Further, the mould 1 can be characterized by a height H, calculated as a distance between the bottom wall 2 and an upper end of the lateral wall 3. The height H is for example illustrated in Figures 2, 12 and 14 and can be calculated orthogonally to the bottom wall 2. The height H can be of at least 3 cm or 7 cm or 11 cm.

Particularly, a mould 1 according to the present invention can be characterized by a ratio of the height H to the maximum distance A at least equal to 0.15 or 0.6 or 0.7.

The lateral wall 3 can perimetrally develop with respect to the bottom wall 2; under operative conditions of the mould 1 the lateral wall 3 and the bottom wall 2 can be reciprocally oriented and/or positioned in order to define a cavity 6. Particularly, under operative conditions of the mould 1 the lateral wall 3 can emerge away from the bottom wall 2, defining a cavity 6 delimited below by the bottom wall 2 and laterally by the lateral wall 3. In the context of the present description, the term operative conditions of the mould 1 means the condition wherein the mould 1 takes a shape suitable for receiving a dough to be baked; a mould 1, under operative conditions, is for example illustrated in Figure 1. In other words, the operative conditions of a mould 1 correspond to the normal conditions of operation of a baking mould for foodstuff.

The lateral wall 3 can have an end portion 3a, which can perimetrally develop with respect to the lateral wall 3 and is preferably characterized by a geometrical outline at least partially curvilinear and/or rectilinear. Particularly, the geometrical outline of the end portion 3a of the lateral wall 3 can be of a mixed type; in other words, such geometrical outline can be formed by at least partially rectilinear portions and by at least partially curvilinear portions. Figure 1 illustrates for example a mould 1 wherein the end portion 3a of the lateral wall 3 has a mixed geometrical outline. Particularly, the end portion 3a of the lateral wall 3 can have a regular alternation between one or more rectilinear portions and one or more curvilinear portions. Alternatively, the geometrical outline of the end portion 3a can be defined only by rectilinear portions .

In the scope of the manufacturing process of the mould 1, it can be made by die-cutting a sheet of paper material; the geometrical outline of the end portion 3a of the lateral wall 3 of the mould 1 can be therefore defined by the sharp outline of the hollow punch used for cutting. Following the die-cutting operation, the mould 1 can take a complete opened condition, in which the lateral wall 3 of the mould 1 lies substantially on the same plane of the bottom 2 of the mould 1, as illustrated in Figure 6, wherein the geometrical outline of the end portion 3a made by die-cutting is also visible. In other words, Figure 6 illustrates a flat blank made of paper material.

The mould 1 can have an inner surface 7 and an outer surface 8, which can be defined, particularly with reference to the operative conditions of the mould 1, by one or more layers of paper material which the mould 1 is made by. The inner surface 7 and the outer surface 8 develop at the bottom wall 2 and at the lateral wall 3 and are reciprocally opposed with reference to the body of the mould 1. With reference to the operative conditions of the mould 1, the inner surface 7 is the surface of the mould 1 facing the cavity 6 of the mould 1, while the outer surface 8 is opposite to the inner surface 7 with reference to the body of the mould 1. In other words, with reference to the operative conditions of the mould 1, the inner surface 7 represents the surface of the mould 1 suitable for contacting the dough of the foodstuff to be baked, while the outer surface 8 of the mould 1 represents the surface by which the operators and/or the automatic machines contact the mould 1 upon handling and/or moving the mould 1 and/or of the foodstuff received inside the mould 1.

Particularly, at least one between the inner surface 7 and the outer surface 8, preferably at least the inner surface 7, can be coated by a film of oil-repellent and/or water-repellent material; such coating can be polyethylene-based, for example.

The paper material which is preferably made of the mould 1 can consist in a single layer or in a first and in a second layers 9, 10.

Preferably, the paper material has a grammage at least equal to or greater than 125 g/m 2 , particularly at least equal to, or greater than 175 g/m 2 . The grammage can be less than 200 g/m 2 , preferably about 150 g/m 2 .

The layers forming the paper material can be smooth and/or embossed and/or corrugated. In the context of the present description, the term smooth layer means a layer devoid of surface roughness obtained by specific processings, for example a smooth layer is neither embossed nor corrugated. A smooth layer of paper material can be particularly coated by a film of oil- repellent and/or water-repellent material; such coat can be for example polyethylene-based.

The paper material formed by a single layer can be coated by a film of oil-repellent and/or water-repellent material, for example polyethylene-based. The single layer of paper material is preferably smooth., under operative conditions of a mould 1 of paper material comprising a single layer, the single layer of paper material can define the inner surface 7 and the outer surface 8 of the mould 1. The inner surface 7 and the outer surface 8 of the mould 1 made of paper material comprising a single layer, can be smooth and particularly both are coated by a film of oil-repellent and/or water-repellent material; such layer can be for example polyethylene-based.

With reference to a mould 1 made of paper material consisting of a first and second layers 9, 10, the first layer 9 can define the inner surface 7 of the mould 1, and the second layer 10 can define the outer surface 8 of the mould 1. The first layer 9 can be smooth; preferably, the first layer 9 is coated by a film of oil-repellent and/or water-repellent material, for example polyethylene-based. With reference to the second layer 10, it can be embossed and/or corrugated. Particularly, the second layer 10 can be embossed according to a first series of embossing lines parallel to each other and a second series of embossing lines parallel to each other. Preferably, the first and second series of embossing lines are reciprocally transversal, particularly perpendicular. Specifically, the second layer 10 can be homogeneously embossed at the outer surface 8 of the lateral wall 3 of the mould 1. Alternatively, the second layer 10 can be differently embossed at the outer surface 8 of the lateral wall 3. The homogeneous and/or differential embossing of the second layer 10 at the outer surface 8 of the lateral wall 3 can be made for optimizing the heat transmission at the outer surface 8 of the mould 1. A detail of the outer surface 8 of a mould 1 wherein the second layer 10 is embossed is shown in Figure 5 and in the detailed image of the mould 1 in Figure 16.

The baking mould 1 for foodstuff can be further subjected to one or more creasing steps in order to compress and/or yield the paper material of the mould 1 in order to facilitate its folding. The term folding of the mould 1 means the operations consisting of folding the lateral wall 3 with respect to the bottom wall 2 of the mould 1 and/or reciprocally folding portions of the lateral wall 3.

The creasing step can be made simultaneously with the die-cutting by means of suitable die-cutters or after the die-cutting. The creasing can be performed on the mould 1 at the lateral wall 3 of the mould 1 and/or of the bottom wall 2. The creasing compresses and/or yields the paper material which the mould 1 is made of, by obtaining on it one or more creasing lines 11, usually a plurality of creasing lines 11. Folding the mould 1, particularly at its lateral wall 3, is usually performed at the creasing lines 11.

The creasing lines 11 can be made on the mould 1 in order to define the polygonal perimeter 4 of the bottom wall 2, as for example shown in Figure 6. With reference to the creasing lines 11 developing at the lateral wall 3, they can develop from the vertexes of the polygonal perimeter 4 characterizing the bottom wall 2. The creasing lines 11 developing from the vertexes of the polygonal perimeter 4 of the bottom wall

2 can define at the lateral wall 3 one or more sectors 12, particularly a plurality of sectors 12 and one or more substantially triangular portions 13, particularly a plurality of substantially triangular portions 13. Preferably, at least one creasing line 11 at the lateral wall 3 of the mould 1 develops from one or more vertexes of the polygonal perimeter 4 of the bottom wall 2. Particularly, at least one creasing line 11 at the lateral wall 3 of the mould 1 can develop from each vertex of the polygonal perimeter 4 of the bottom wall 2; preferably two creasing lines 11 at the lateral wall

3 of the mould 1 develop from each vertex of the polygonal perimeter 4 of the bottom wall.

Generally, at least four creasing lines 11 can develop from at least one vertex, particularly from each vertex, of the polygonal perimeter 4 of the bottom wall 2, as illustrated in Figure 6; two creasing lines 11 can develop at the lateral wall 3 and the other two creasing lines 11 can develop at the bottom wall 2. The two creasing lines 11 developing from one same vertex at the bottom wall 2 can define two sides 5 of the polygonal perimeter 4 of the bottom wall 2.

Each pair of creasing lines 11 developing at the lateral wall 3 from a same vertex of the polygonal perimeter 4 can extend until they join the geometrical outline of the end portion 3a of the lateral wall 3, defining a substantially triangular portion 13. The development of two creasing lines 11 at the lateral wall 3 from the same vertex of the polygonal perimeter 4 can therefore define a substantially triangular portion, which develops along the lateral wall 3 between the two creasing lines 11. Preferably, the two creasing lines 11 reciprocally develop away from a same vertex. The substantially triangular portion 13 can develop at the inner surface 7 and the outer surface 8 of the lateral wall 3. The substantially triangular portion 13 is defined laterally by two creasing lines 11 developing at the lateral wall 3 from a same vertex and above by the geometrical outline of the end portion 3a of the lateral wall 3. Particularly, the shortest side of the substantially triangular portion 13 can be defined at the geometrical outline of the end portion 3a of the lateral wall and can define above the substantially triangular portion 13. The shortest side of the triangle characterizing the substantially triangular portion 13 can be at least partially rectilinear in case, at the substantially triangular portion 13, the geometrical outline of the end portion 3a of the lateral wall 3 is of a rectilinear and/or polygonal type or can be at least partially curvilinear in case, at the substantially triangular portion 13, the geometrical outline of the end portion 3a of the lateral wall 3 is of a curvilinear type. Preferably, the shortest side of the triangle characterizing the substantially triangular portion 13 is substantially rectilinear.

Further, the lateral wall 3 can be geometrically subdivided into more sectors 12 by the creasing lines 11 developing from two adjacent vertexes. The term adjacent vertex means particularly the vertexes lying on a same side 5, which are spaced by a length L from the side 5.

Each sector 12 of the lateral wall 3 can have a shape defined by four sides, which can be rectilinear and/or curvilinear. Particularly, each sector 12 of the lateral wall 3 can be perimetrally determined by a creasing line 11 defining a side 5 of the polygonal perimeter 4 of the bottom wall 2, by two creasing lines 11 which extend at the lateral wall 3, respectively developing from said two adjacent vertexes of a side 5 of the polygonal perimeter 4 of the bottom wall 2, and by a portion of the geometrical outline of the end portion 3a of the lateral wall 3 defined by the two creasing lines 11.

Preferably, the lateral wall 3 can be characterized by a regular alternation of a sector 12 and a substantially triangular portion 13; in other words, each substantially triangular portion 13 can be interposed between two sectors 12 and viceversa, as shown in Figure 6.

The creasing lines 11 developing at the lateral wall 3 of the mould 1 from two adjacent vertexes, can be spaced by a distance D. The distance D defines the width of each sector 12 and can vary along the lateral wall 3, particularly along a direction substantially parallel to the development direction of one or more creasing lines 11 defining the sectors 12 at the lateral wall 3, as shown in Figure 6. In other words, the distance D can vary, preferably increasing along the development of each sector 12 of the lateral wall 3, from the polygonal perimeter 4 of the bottom wall 2 and continuing towards the end portion 3a of the lateral wall 3. The distance D between the creasing lines 11 defining each sector 12 can be calculated for each sector 12 parallelly to the development direction of the side 5 of the polygonal perimeter 4 defining the sector 12 at the bottom wall 2. At the polygonal perimeter 4 of the bottom wall 2, the distance D can be for example calculated as the distance between two creasing lines 11 respectively developing from two adjacent vertexes of a same side 5 of the polygonal perimeter 4 of the bottom wall 2. In other terms, at the polygonal perimeter 4 of the bottom wall 2, the distance D can substantially coincide with the length L of the sides 5 of the polygonal perimeter 4 of the bottom wall 2. Particularly, the minimum distance D between two adjacent creasing lines 11 can be defined at the polygonal perimeter 4 and can be equal to the length L of the sides 5.

With reference to the folding of the lateral wall 3 of the mould 1, the sectors 12 and the substantially triangular portions 13 of the lateral wall 3 can be reciprocally oriented and/or positioned. Folding the mould 1 is preferably executed during the steps of drawing a flat blank of paper material or in a successive step with respect to it. With reference to the drawing, it has substantially the function of orienting the lateral wall 3 with respect to the bottom wall 2 by folding the mould 1 at the polygonal perimeter 4 of the bottom wall 2.

Following the die-cutting and the creasing steps, the mould 1 can substantially take a completely opened condition, in which the mould 1 is substantially flat, as shown in Figure 6. In order to correctly orienting the lateral wall 3 with respect to the bottom wall 2, a mould 1 drawing and/or folding step is provided, by which the lateral wall 3 is caused to emerge from the bottom wall 2. In other words, the drawing and/or folding steps orient the lateral wall 3 with respect to the bottom wall 2 by suitably folding the paper material which the mould 1 is made of at the creasing lines 11. The drawing and/or folding steps can be executed from a flat blank of paper material, as the one shown in Figure 6. Particularly, the mould 1 can be folded along the creasing lines 11 defining the polygonal perimeter 4 of the bottom wall 2 in order to cause the lateral wall 3 of the mould 1 to emerge away from the bottom wall 2. By folding the lateral wall 3 with respect to the bottom wall 2, the lateral wall 3 is suitably oriented with respect to the bottom wall 2 and the mould 1 cavity 6 is formed .

Drawing the flat blank of paper material forms pleats 14 at the lateral wall 3 of the mould 1. The pleats 14 can be substantially uniform along all the development of the lateral wall 3; the function of the pleats 14 consists of compensating the surplus of material at the lateral wall 3 caused by the flat blank drawing.

Each pleat 14 can comprise a lap region 15; the number of the lap regions 15 can be particularly equal to the number of sides 5 of the polygonal perimeter 4 of the bottom wall 2. Particularly, the number of lap regions

15 can be comprised between 6 and 14 and/or between 8 and 12; preferably, the number of lap regions 15 is equal to 10.

Each lap region 15 can comprise a first and second overlapping regions 16, 17. The first overlapping region

16 comprises at least a first and a second portions 18, 19 of the inner surface 7 of the lateral wall 3, which can substantially face each other. Preferably, the first portion 18 of the inner surface 7 of the lateral wall 3 of the mould 1 is defined at a substantially triangular portion 13 and the second portion 19 of the inner surface 7 of the lateral wall 3 of the mould 1 is defined at a sector 12 adjacent to the substantially triangular portion 13, as illustrated in Figure 4.

The second overlapping region 17 comprises at least a first and a second portions 20, 21 of the outer surface 8 of the lateral wall 3, which can substantially face each other. Preferably, the first portion 20 of the outer surface 8 of the lateral wall 3 of the mould 1 is defined at a sector 12 adjacent the substantially triangular portion 13 and the second portion 21 of the outer surface 8 of the lateral wall 3 of the mould 1 is defined at a substantially triangular portion 13, as shown in Figure 4.

At each lap region 15, particularly at the first and the second overlapping regions 16, 17, two sectors 12 can be al least partially overlapped; such overlapping can refer also to the substantially triangular portion 13 interposed between the two sectors 12. Such overlapping can be executed so that the first and/or the second series of embossing lines of one of the at least partially overlapped sectors 12 can be parallel and/or transversal, particularly normal, to the first and/or to the second series of embossing lines of the other sector 12.

In order to explain how the steps of folding the lateral wall 3 of the mould 1 are executed, it will be made reference to a single pleat 14 and to the relative lap region 15.

The operation of folding the lateral wall 3 at a lap region 15 occurs substantially by a rotation of the substantially triangular portion 13 with respect to two sectors 12 adjacent thereto; at the end of the rotation, the substantially triangular portion 13 faces and/or abuts against the two adjacent sectors 12 at the first and the second overlapping regions 16, 17. The substantially triangular portion 13 rotation can be executed by moving at least one of the two sectors 12 adjacent thereto, particularly both. The movement of at least one of the two sectors 12 and/or of the substantially triangular portion 13 can be for example automatically executed by the drawing operation.

At the first overlapping region 16, following said rotation and/or movement, the first portion 18 of the inner surface 7 of the lateral wall 3 can be frontally positioned with respect to and/or can abut against the second portion 19 of the inner surface 7 of the lateral wall 3, and the first portion 20 of the outer surface 8 of the lateral wall 3 can be frontally positioned with respect to and/or can abut against the second portion 21 of the outer surface 8 of the lateral wall 3.

A detail of the lateral wall 3 of a mould 1 in a step following the folding one is for example illustrated in Figure 4, wherein at the first overlapping region 16 the first portion 18 of the inner surface 7 of the lateral wall 3 is frontally positioned with respect to and faces the second portion 19 of the inner surface 7 of the lateral wall 3, and at the second overlapping region 17 the first portion 20 of the outer surface 8 of the lateral wall 3 is frontally positioned with respect to and faces the second portion 21 of the outer surface 8 of the lateral wall 3.

Upon the movement of one or more substantially triangular portions 13 and/or of one or more sectors 12, the axis which the one or more substantially triangular portions 13 and/or one or more sectors 12 rotate around, can be for example defined by a creasing line 11 laterally delimiting a substantially triangular portion 13. The previously described reciprocal positioning of a substantially triangular portion 13 with respect to the two adjacent sectors 12 at each lap region 15 can also consist of translational movements; in other words such positioning cannot be executed by a simple rotation of the substantially triangular portion 13 with respect to at least one adjacent sector 12 or viceversa, but can also comprise one or more translations. Particularly, the reciprocal positioning and/or movement of a substantially triangular portion 13 with respect to the two adjacent sectors 12 at one lap region 15 can be executed by one or more rotations and/or translational and/or rototranslational movements, which can involve also at least one of the two sectors 12 adjacent to the substantially triangular portion 13.

The reciprocal positioning of a substantially triangular portion 13 and of the two adjacent sectors 12 can define the outline of the pleat 14; the pleats 14 can have a substantially "Z" outline, which can be visible according to an axonometric view, as illustrated in Figure 1, or also according to a cross-section, as illustrated in Figure 3.

After the folding, the first portion 18 of the inner surface 7 of the lateral wall 3 and/or the second portion 19 of the inner surface 7 of the lateral wall 3 and/or the first portion 20 of the outer surface 8 of the lateral wall 3 and/or the second portion 21 of the outer surface 8 of the lateral wall 3 can be reciprocally constrained and/or fixed.

Particularly, with reference to the first overlapping region 16, the first portion 18 of the inner surface 7 of the lateral wall 3 can be pasted and/or heat-sealed to the second portion 19 of the inner surface 7 of the lateral wall 3, or viceversa. Preferably, a paste layer can be applied at the first portion 18 of the inner surface 7 of the lateral wall 3 and/or at the second portion 19 of the inner surface 7 of the lateral wall 3.

Particularly, with reference to the second overlapping region 17, the first portion 20 of the outer surface 8 of the lateral wall 3 can be pasted and/or heat-sealed to the second portion 21 of the outer surface 8 of the lateral wall 3. Preferably, a paste layer can be applied at the first portion 20 of the outer surface 8 of the lateral wall 3 and/or at the second portion 21 of the outer surface 8 of the lateral wall 3. With reference to the arrangement of the lap regions 15, they can be arranged according to an uniform trend along the lateral wall 3; particularly, the lap regions 15 can be equally spaced from each other.

According to an embodiment of the present invention, the end portion 3a of the lateral wall 3 can be folded outwards from the cavity 6 in order to form a lapped edge 22. A mould 1 comprising a lapped edge 22 obtained by folding the end portion 3a of the lateral wall 3 is for example illustrated in Figure 11 and in Figure 12. The lapped edge 22 can perimetrally develop with respect to the cavity 6, as shown in Figure 11. Preferably, in order to form the lapped edge 22, the end portion 3a of the lateral wall 3 is folded outwards from the cavity 6 and away from it, in order to form with the outer surface 8 of the mould 1 at the end portion 3a of the lateral wall 3, a substantially acute angle, as illustrated in Figure 12. The substantially acute angle preferably takes a value less than 25°; particularly the lapped edge 22 can contact the outer surface 8 of the mould 1. The edge 22 can be fixed, particularly by pasting and/or heat-sealing, to the outer surface 8 of the mould 1 at the end portion 3a of the lateral wall 3. Particularly, a paste layer can be applied at the outer surface 8 of the end portion 3a of the lateral wall 3. Alternatively, in order to form the edge 22, the end portion 3a of the lateral wall 3 can be simply folded outwards from the cavity 6 and away from it without applying a paste layer.

According to another embodiment of the present invention, the end portion 3a of the lateral wall 3 can be at least partially rolled up outwards from the cavity 6 in order to form a curly edge 22; such embodiment is shown in Figure 13 and in Figure 14. At the end portion 3a of the lateral wall 3 designed to be rolled up, a paste layer can be applied, in order to fix and stiffen the edge 22. Alternatively, the curly edge 22 can be simply made by rolling up the end portion 3a of the lateral wall 3 outwards from the cavity 6, without providing any paste application.

The present invention enables to obtain one or more of the following advantages and to solve one or more of the problems found in the prior art. First of all, the baking mould according to the present invention enables to homogeneously bake the foodstuff, particularly at the bottom wall .

Further, a baking mould according to the present invention has a lateral wall provided with a greater stiffness .

A baking mould according to the present invention can be opened in a step after baking the foodstuff contained therein, in order to take a completely or partially opened condition facilitating the cutting operations of the foodstuff contained therein, and further can be reused in subsequent consuming operations of the same foodstuff. The shape of the lateral wall of the mould can further aid in defining the width of the slices which the confectionery product can be subdivided into.

Further, the invention is an user-friendly, easily and economically manufacturable implementation.
