Description:
"PACKING FOR CLEANING TOOLS"

Field of application

The invention relates to a packing for cleaning tools that is generally usable to contain and transport in a protected manner one or more cleaning tools stacked on pallets of a standardized measure, optimizing the space occupied.

State of the art

It is known that in order to ship a quantity of objects in general, and in the specific case cleaning tools such as broom bases, brushes and the like for industrial use and/or road use, so-called "pallets" are typically used, i.e. wood bases that have standard dimensions predetermined by convention, onto which the packings that contain the cleaning tools inside are disposed in a prearranged manner to form a stack that is then wrapped by a containing strap.

Cleaning tools are typically inserted into a transport packing made of cardboard, usually in the form of a parallelepiped box, also in this case disposed according to a predetermined order so as to contain the greatest possible number thereof.

It shall be specified that hereinafter the definition "cleaning tools" indicates, by way of example, broom bases provided with bristles, but without sticks, brushes of various shapes, such as for instance cup brushes or cylindrical brushes, and all those tools that are provided with flexible bristles designed to clean surfaces.

Typically, as is known, broom bases, particularly those for industrial use and/or road use, comprise a support body having a flat and elongate shape, the function of which is to support the bristles that protrude from a face thereof that is considered lower.

On an opposite face, that is the upper with respect to the one from which the bristles extend and parallel thereto, the support body is provided with a standard connector, which is typically raised, to allow to attach the handling stick to the base.

Similarly, cylindrical brushes comprise a central body, which is also cylindrical, on which the ends of bundles of flexible bristles, extending in an outer-radial direction, are planted according to a predetermined arrangement.

Cup brushes, on the other hand, comprise a circular, flat base having a face on which the ends of the bundles of bristles are planted and an opposite face provided with connection elements to a sweeping machine.

The bristles of the cup brushes are planted in the face in such a manner that they are inclined and divergent outwards.

The shape and the dimensions of the packings of these cleaning tools in general, considering the standardized dimensions of Euro-pallets or of boxes, are, therefore, of great importance to optimize the spaces occupied in forming the stack or the transport package, so that the greatest possible number of packings, and hence of cleaning tools, are loaded onto each pallet, yet causing the overall dimensions of the stack formed to remain within the outer dimensions of the pallet.

Currently, known packings used to contain cleaning tools do not have any effective measure for holding each cleaning tool firm on their inside during transportation, and this represents a drawback of the known state of the art.

In fact, cleaning tools move during the handling of packings that contain them, and this causes the bending of the bristles that lean against the packing walls.

These bendings remain permanent in many cases, and cleaning tools appear damaged even if they are new.

In other words, the self-weight of each cleaning tool weighs on the mass of bristles when the latter lean against the walls of the packings, forcing them in this position for long periods of time and causing deformations of the bristles that may become permanent.

Another problem of the known prior art consists in the fact that some known packings, above all those shaped like a box, are substantially expensive and, since they are made of a material intended to be disposable, the selling prices of each cleaning tool must comprise also an amount that covers the cost of packings, which, at the end of the production and marketing chain, must be paid by the buyer.

Some types of less expensive packings, on the other hand, typically those intended to contain broom bases without sticks, have protective surfaces with only limited dimensions and, above all, their conformation does not allow to contain in some way also the connectors for the sticks that are made in a raised form with respect to the bases and that, hence, remain protruding from the packing.

This prevents an optimum arrangement between adjacent packings, for instance placing the two connectors for the sticks in an upside-down position one with respect to the other, on the pallets or in the boxes.

In fact, this arrangement generates empty, unusable interspaces in a stack, causing the creation of stacks formed with a limited number of packings that can be loaded or inserted into each box.

Presentation of the invention

An object of the invention is to improve the known state of the art.

Another object of the invention is to provide a packing for cleaning tools that allows to keep intact the bristles they are equipped with, holding them fixedly firm during the transportation towards the marketing destinations.

Another object of the invention is to achieve a packing for cleaning tools that allows to optimize spaces in the formation of stacks on a pallet.

A further object of the invention is to achieve a packing for cleaning tools that has a very simple and, hence, very economical structure.

A further object of the invention is to achieve a packing for cleaning tools that can be re-used at least partly for the accommodation of the cleaning tools after their use.

According to an aspect of the invention a packing for broom bases is provided, in accordance with the features of claim 1.

Further aspects of the invention are indicated in the dependent claims.

The invention allows to achieve the following advantages:

- protecting the integrity of the bristles during transportation and handling of the packings on the pallets, avoiding undesired deformations thereof;

- optimizing spaces in the formation of stacks to be loaded on transport pallets or inside containers, limiting the presence of empty interspaces;

- re-using the packing at least partly both to accommodate the cleaning tools, and to make new packings, reducing the waste of disposable material.

Detailed description of a preferred example of embodiment With reference to Figure 9, 1 indicates a cleaning tool, in this specific case a broom base without stick, which comprises a body 2 having a flat and elongate shape, which has a longitudinal axis "X" and two parallel and opposing faces, namely a lower face 2a that is provided with a group of bristles 3 (not illustrated) and an opposite upper face 2b from which a connector 4 for a handling stick "M" rises, respectively.

The body 2 has a reinforcement portion 5 that connects it to the connector 4 without interruptions and in which transverse through openings 6 are made, the function of which will be explained further below.

With reference to Figures 1, 11 and 12 it is noticed that a packing for broom bases 1 is indicated with 10.

The packing 10 has a cross section that has the shape of an isosceles trapezoid and that forms a solid, which is open at the two ends and has a first face 11 considered the base face, hereinafter simply referred to as the base 11, and an opposite second face 12 considered the upper one, hereinafter briefly referred to as the upper face 12.

The base 11 and the upper face 12 are joined together by two flanks 13 and 14, which form the oblique sides of the solid and of the trapezoid cross section.

In the upper face 12 two symmetrical openings 15 are made between which a central zone 12a is defined that is shaped so as to achieve an openable closure, indicated as a whole with 16.

In detail, the closure 16 comprises a first lip 17 that projects from one of the flanks, in the specific case from the flank 14, which, in the proximity of the conjunction with the latter, has a longitudinal notch 18.

A corresponding flap 19, which extends in a foldable manner from a second lip 20, which, in turn, projects in an overhanging manner from the opposing flank 13, is designed to fit into the notch 18: when the flap 19 fits into the notch 18, the packing 1 is closed, while when it is extracted the packing 1 is opened again.

As can be seen in detail in Figure 11, but also in Figures 4, 5, 6, in the two flanks 13 and 14 two or more notches or holes 13a and 14a, 13b and 14b are made, coaxial two by two, more precisely in the proximity of two opposing sides of the flanks.

Blocking means of the bases 1 are designed to be inserted into these notches or holes 13a and 14a, 13b and 14b when the bases are inserted inside the packing 10 for their transportation.

Blocking means can be made in different shapes, but, to block specifically the broom bases, they have in common the feature of passing transversely through one of the walls of the packing and of being positioned, in one version, below the body 2, getting partly in, or passing entirely through, the group of bristles 3, as visible in Figures 4, 5, 6, or, in another version, of engaging with the same body 2 as visible in Figure 33.

In a first form of embodiment visible in the Figures 6 and 9, the blocking means MB l comprise two plates 21 and 22 that are provided on internal opposite faces 21a and 22a with pins 23 and 24 that protrude from them and that, as previously said, are designed to be inserted immediately under the body 2, inserted among the group of bristles 3, in a slightly distanced position from the lower face 2a.

The two plates 21 and 22 have also respective extensions 25 and 26 that stretch forward one towards the other and that have female and male profiles, respectively, that are shaped in a manner such that they mutually penetrate into each other when the two plates 21 and 22 are applied on the flanks 13 and 14 of the packing 10 and the two pins 23 and 24 are inserted, as a consequence, into the respective holes 13a and 14a, as can be seen schematically in Figure 6.

The two extensions 25 and 26 are designed, in the configuration of interpenetration into one another, to pass through the through openings 6 of the reinforcement portion 5, when the two plates 21 and 22 are applied on the packing 10, as can be seen in detail in the Figures 7 and 9, acting as an attachment support for the body 2 when the packing 10 encloses the broom base 1.

In the Figures 4 and 5 further possible forms of embodiment of the blocking means of the broom base 1 in the packing 10 are illustrated.

In detail, with reference to Figure 4, it is noticed that the blocking means MB2 are executed in the form of two pins 27 that are inserted transversely between the two flanks 13 and 14, for instance in the couples of holes 13a and 14a, 13b and 14b passing through the mass of bristles 3.

Each pin 27 is immediately below the lower face 2a of the body 2, in a manner such that the two pins 27 keep the body in contact with the first lip 17 and with the second 20, which form the closure 16.

Similarly, with reference to Figure 5, in the blocking means the pins 27 were replaced by a further couple of buttons that can be applied on the flanks 13 and 14 and that have respective segments of pins 28 and 29 that are inserted into the holes 13a and 14a, 13b and 14b, oriented the ones towards the others, acting also in this case as a support for the body 2, keeping it substantially in contact with the closure 16.

With reference to Figure 8, a possible form of re-use of one of the plates 21 or 22, in this specific case the plate 21, can be observed, which, after the packing 10 has been removed from the broom base 1, can be fixed to a wall 30, so that it can be used as a support, both to hang the stick "M" of a complete broom on the pin 23, and as a possible clothes-hanger with the extension 25.

With reference to Figures 1 and 2, the system of stacking two broom bases 1 provided with their respective packings 10 is noticed.

In detail, the two broom bases 1 and the respective packings 10 that contain them are placed upside-down one with respect to the other and each reinforcement portion 5 of a broom base 1 that protrudes from the upper face 2b of the latter is received inside the opening 15 of the opposite packing, so that between two adjacent packings 10 there are no interfering elements that can distance them from one another.

With reference to Figure 3, it can be noticed how a layer of packings 10 which contain broom bases 1 is achieved, to form a stack that is visible in Figure 10, already loaded on a pallet 30 and with each layer wrapped by containing straps 31.

With reference to Figure 13, it can be noticed that the packing 10 has a series of holes or notches 13a, 13b, 14a, 14b that are made repetitively in a row in the flanks 13 and 14, in a manner such that the plates 21 and 22 can be positioned in a suitable manner with respect both to the dimensions of the broom bases, and to the arrangement of the through openings 6.

With reference to Figure 14 it is noticed that the packing 10 has the upper face

12 that is completely closed since it is designed to receive inside of it a broom base 2 that is provided with a connector 4 for the stick that does not protrude in an evident manner from the upper face 2a of the body 2.

In this case, the attachment of the body 2 of the broom base is achieved again by means of the two plates 21 and 22 inserted into the couples of holes 13a and 14a or 13b and 14b, or into other additional couples, and with the respective extensions 25 and 26 that engage into a through opening 30 made in the thickness of the body 2, and fit in together mutually, as indicated in Figure 7.

With reference to Figure 15, a further form of attachment of the body 2 to the packing 10 is noticed again, according to which the two plates 21 and 22 have the respective extensions 25 and 26 having a limited length and engaged in corresponding seats 31 that are formed bilaterally in the thickness of the body 2. With reference to Figures from 16 to 30, both a different shape of the packing, indicated by 100, in detail a parallel epipedal shape, and further possible forms of embodiment of the blocking means of the cleaning tools inside the containing space indicated by 101 are observed.

This specific shape of the packing 100 is designed to contain cleaning tools in the form of cylindrical brushes 130 or cup brushes 150.

The packing 100 for containing one or more cylindrical brushes 130, as in the version for containing broom bases 2, has a longitudinal axis "X", four peripheral walls and, in addition thereto, two end walls 131a and 131b, at least one of which is openable.

To block a cylindrical brush 130 inside the box 131 in a position substantially coaxial to the axis "X", the blocking means MB3 provide that on both end walls 131a and 131b a respective base 132 is able to be positioned that is shaped in the form of a rectilinear ledge, hereinafter shortly the ledge 132, that after the use can be re-used in other packings and that can have both a fixed length, such as to allow for a precision insertion thereof, and possibly slightly forced, between two opposing corners 131c and 13 Id of the box 131, as shown in Figure 17, and can be extensible, as shown schematically in Figure 25 and able to be blocked according to predetermined positions obtained, for instance, with through holes 132a designed to receive suitable lock pins, which are not illustrated since they are known.

Advantageously, the opposite ends of the ledge 132 can also be cut directly at a right dihedral angle or can be provided with couples of oriented fins 133 that are arranged at a right angle between them, and that are able to lean inside the surfaces of the couples of walls of the box 131 that converge in the corners 131c and 13 Id.

A perpendicular upright 134, which is likewise re-usable after use, is able to be fitted on the ledge 132, for instance by means of a socket-type coupling, indicated altogether by 135, that extends substantially for the entire length of the axis "X" of the box 131.

As can be seen in the Figures, the upright 134 is provided at both ends with the socket-type coupling 135, so that it can receive in engagement at both ends two respective ledges 132 that are equal to each other and inserted between both corners 131c and 131d.

The upright 134 has dimensions that are such as to allow to fit on it, with precision, the axial cavity 130a of a hollow cylindrical support of a cylindrical brush

130, as indicated in Figure 17, or a plurality of concentrical axial cavities 130a of modular elements that form approached cylindrical supports of a cylindrical brush 130 formed by several modular brush elements.

Additionally, the upright 134 is provided on the side surfaces with a series of aligned holes 136 into which one or more pins 137 can be removably fitted, which, when fitted, hold the ends of the support 130a between them, in such a manner that this cannot slide freely on the upright 134, but rather is blocked between them.

By inserting the pins 137 in a preset manner depending on the axial dimensions of the brush 130, it is possible to keep the bristles 3 of the brush 130, in particular the end bristles, slightly distanced from the inner and end walls 131a and 131b of the box

131, as visible in detail in the Figures 18 and 19.

With reference to Figure 23, a version of the box 131 can be noticed that is able to contain a plurality of brushes 130, in the specific case four cylindrical brushes 130.

In this case, the base is formed by two ledges 132 coupled to one another in a cross shape, in this specific case with arms 132a and 132b coupled perpendicular to one another with couplings 135 and each of which is engaged between the inner alternate corners of the box 131.

On each arm 132a, 132b, two uprights 134 are then mounted which altogether add up to four uprights 134 parallel to one another and substantially equal to those described previously.

Two further ledges 132, which are arranged in a cross shape, like those that form the base, are then coupled at the upper ends of these in a manner such as to form a substantially fixed frame that is provided with four parallel uprights 134 onto which the respective inner cylindrical supports 130a can be fitted.

Also in this version, all the uprights 134 have the holes 136 on the respective surfaces that are designed to receive the removably fitted pins 137.

The frame thus obtained is able to be disassembled and re-assembled in other packings as required, and is able to be inserted into the space 101 to contain in a fixed manner four cylindrical brushes 130, without the bristles 3 being in contact with the end walls 131a and 131b and not even with the four peripheral walls.

With reference to Figures from 24 to 28 a further possible version of execution of blocking means MB4 of one or more cylindrical brushes inside a box 131 is illustrated.

In detail, the base that is designed to be inserted into the space 101 comprises a plate 200, which is also reusable for other packings after use, from which four guides 201 rise that are arranged in the shape of a cross and that are designed to receive, in their inside and slidably, correspondent ledges 132 (see in particular Figure 26) and able to blocked in predetermined positions with the engagement of pins in a series of transverse holes 132a achieved correspondingly both in the guides 201 and in the ledges 132.

At the center of the plate 200 there are also provided, in a raised form, couples of ribs 203 that are slightly distanced from one another and that form a cross-shaped concavity into which an upright 204 is designed to be inserted with precision onto which, like in the previous versions of the packing according to the invention, an inner cylindrical support 130a of a cylindrical brush 130 is designed to be fitted with precision.

Also the upright 204 has, on the walls, series of holes 205 (see in detail Fig. 28) that are designed to receive respective fitted pins 137.

Like in the previously described version, also in this case it is possible to provide the packing of several cylindrical brushes 130 in only one box 131.

This version is represented in Figure 24, in which both the brushes 130 and the uprights 204 were omitted for a better clarity.

With reference to Figures 29 and 30 a further possible form of embodiment of the packing according to the invention is noticed, which is particularly suitable for containing cup brushes 150 or brushes having a support 300 in the shape of a circular crown that defines a central hole 302 and from which bristles 3 extend that are divergent outwards.

As is seen in the Figures, the box 131 has again a parallelepipedal shape and in its internal space 303 a cup brush 150 is arranged that has the support 300 which rests directly on one of the end walls, in the specific case on the wall 131b considered the bottom wall.

The opposite end wall 131a, considered the upper wall, is formed by two closable flaps. Inside the space 303 defined in the box 131 a ledge 132 is arranged, like in the previous versions, possibly with an adjustable length, but which does not form the base of the blocking means, but rather the upper part.

In other words, after arranging a cup brush 150 inside the space 303, the ledge 132 is mounted by placing it between two internal concave corners 131c and 13 Id.

This ledge 132 is provided with a support body 304 that is facing the inside of the cup brush 150, in such a manner that it fits between the bristles 3 thereof until it engages with a shaped portion 306 in the central hole 302.

The engagement between this support body 304, the central hole 302 and the ledge 132 holds the cup brush 150 fixed in the space 303 of the box 131.

By closing the flaps of the end wall 131a the cup brush 150 remains completely blocked inside the space 303.

With reference to Figures 31 and 32 a possible form of embodiment of blocking means MB5 of a cylindrical brush 130 inside a packing according to the invention is noticed again.

This version is substantially similar to the one visible in the Figures from 17 to 19, with the difference that the upright 134 is replaced by a simpler support element 138 that is shaped in such a manner that it can be fitted on by an internal support 130a of a cylindrical brush.

The person of skill in the art understands that the same configuration is made symmetrically at the opposite end of the cylindrical brush 130 to contain the latter in a stable manner and without the possibility of movement during the handling of the packing.

With reference to Figures 33, 34 and 35, a further possible form of embodiment of blocking means MB6 of a base of a cleaning tool is noticed, in the specific case again a broom base 2 from a face 2a of which - as previously indicated - the bristles 3 extend.

As is noticed in the Figures, in the broom base 2 a hollowed-out and shaped seat 400 is formed which, however, does not pass through the whole thickness of the broom base 2.

In this hollowed-out seat, a support 401 is designed to be fitted that has a couple of prongs 402 that extend in a fork-like shape from a bent base 403 and that are elastically approachable when a slight compression is applied in the direction of the arrows "Z".

The side walls of the hollow seat 400 are provided with protruding teeth 404 that are designed to engage in corresponding cavities 408 that are made bilaterally in the prongs 402, when these are slidably fitted in the hollow seat 400.

From a part that is considered the upper part of the bent base 403 also an elastic arm 405 extends, oriented substantially parallel to the two prongs 402, which ends in a hook-shaped end 406.

This hook-shaped end 406 is designed to engage into a corresponding opening 407 that is specifically provided in one of the peripheral walls that form the box 131 when the support 401 is completely fitted into the hollow seat 400.

The engagement between the end 406 and the opening 407, together with the coupling between the protruding teeth 404 and the corresponding cavities 408, keep the base 2 firmly fixed inside the box 131.

It must be noticed that, like for a former version described, this support 401 can be reused after the broom base 2 is extracted from the packing, as shown in Figure 35.

In practice, the support 401 can be fixed to a wall "P" in an upside-down position, forming a practical hook to hang an end of a broom stick or rags for cleaning.

Both the packing 10 and the packing 100 can be made in only one piece and of disposable or recoverable material, such as for instance a cardboard or a plastic material sheet, in which the respective faces and/or walls are obtained by punching.

Also the blocking means MB1-MB6 can be made both of disposable and recoverable materials, so that new packings can be achieved without having to use each time new and expensive materials for their manufacturing.

In practice, it has been ascertained that the invention achieves the objectives that it set itself.

The invention as it was conceived is susceptible to modifications and variants, all of them falling within the inventive idea.

Further to that, all the details can be replaced by other elements that are technically equivalent.

In the practical execution, the materials used as well as the forms and dimensions can be any, according to the requirements, without for this departing from the scope of protection of the following claims.
