Description

The invention relates to the field of packaging.

The invention relates more particularly to a box comprising a base and a plurality of side walls each provided with a first horizontal cross and a second horizontal cross each provided with an upper edge and a lower edge defining at least locally the total height of said first, respectively second, horizontal cross, said box having a first connecting piece providing the interface between a pair of adjacent side walls of the plurality of side walls, said first connecting piece being provided for each side wall said pair of adjacent side walls, a receiving housing of a portion of the corresponding first horizontal cross member and a retaining member having an elastically deformable portion and a retaining head. The invention also relates to a connecting piece particularly adapted to the body.

State of the art

A crate usually has a base in the form of a pallet for example wood. Side walls extend from the base so as to form, with said base, a container for receiving any type of object that it is desired to pack / store in said box. When making a box, the side walls can be fixed to each other by nails and / or circled so as to hold each other. Such operations are long and tedious. In addition, the dismantling of a studded body makes it more difficult to recycle or dismantle it.

In this sense, it has been developed a system based on connecting parts that mate with two side walls of the body. The document FR2967976 discloses such a connecting piece which comprises two housings extending in different directions and each intended to accommodate a longitudinal end of a horizontal cross member of a corresponding side wall. The connecting piece further comprises an elastically deformable clip being inserted into a slot made in a horizontal cross member of a side wall of the body. This therefore requires machining the side walls before mounting the box. This machining has a significant cost and weakens the structure of the box. On the other hand, to dismount the box, it is difficult to remove the clip without tools. A system based on connecting parts that mate with two side walls of the body, is not sufficient by itself to ensure maintenance of the body as a whole, including the side walls with the base. To fight against the tearing of the walls out of the base, it is necessary to perform a strapping, expensive tape supply and costly labor.

Document DE102011111010 discloses a comparable connecting piece in which the transverse wall has connecting elements in the form of nails or screws driven parallel to the planes of the side walls. Significant forces applied to the side walls as can be encountered in storage and industrial transport, can then tear the connecting elements and cause a separation of the base against which the strapping is strongly recommended to guard against.

Object of the invention

The object of the present invention is to propose a solution that overcomes the disadvantages listed above.

This object is aimed in particular at the fact that said first connecting piece comprises at least one stop intended to come into contact with at least one lateral face of a base of the box so as to allow the side wall to be held in relation to the base.

Advantageously, said stop is fixed on said at least one lateral face of the base by means of penetrating rods in said at least one lateral face. Particularly in an assembly configuration of said box, for each side wall of said pair of adjacent side walls, the lower and upper edges of the corresponding first horizontal cross member are, at least in part, facing, and preferably in contact with each other. one with the bottom of the corresponding housing of the first connecting piece, and the other with the corresponding retaining head of the first connecting piece.

Preferably, said first connecting piece interfaces with a base of the body, each first horizontal cross member being a lower cross member, and it comprises a second connecting piece comprising, for each side wall of said pair of adjacent side walls, a housing for receiving a portion of the corresponding second horizontal cross member, forming an upper horizontal cross member, and a retaining member comprising an elastically deformable portion and a head in the assembly configuration of said box, for each side wall of said pair of adjacent side walls, the lower and upper edges of the second horizontal crossbar of the side wall concerned are, at least partially, facing each other, and preferably in contact, one with the bottom of the corresponding housing of the second connecting piece and the other with the retaining head of the second connecting piece.

The box may include a plurality of pairs of adjacent side walls, each pair cooperating with a corresponding first connecting piece and a second corresponding connecting piece.

Preferably, the second connecting piece has a shape different from the first connecting piece.

For example, each housing of the second connecting piece has two inner lateral faces disposed facing each other and whose spacing substantially corresponds to the thickness of the second horizontal crosspiece housed in said housing.

For example, each housing of the second connecting piece has an additional internal face whose bracing with one of the two lateral inner faces allows the housing of a portion of the corresponding second horizontal cross member and a part of a vertical upright mounted on said second horizontal cross corresponding.

The invention also relates to a connecting piece which comprises a base provided with an upper face at which are located the two housings intended to cooperate with two side walls of said box, and a lower face, said piece having two stops extending from the lower face and included in different planes, said two stops being intended to come into contact with two adjacent side faces of the base of the body.

Advantageously, the connecting piece comprises two housings extending in different directions, each housing being adapted to receive a corresponding side wall of a box with which said connecting piece is able to be assembled, said piece comprising, at the level of each housing, a retaining member provided with an elastically deformable part and a retaining head, the retaining head having a penetrating shape configured to come into friction along the side wall during the insertion of the lateral wall in the housing to allow the deformation of said elastically deformable portion.

Preferably, the two housings each comprise a first end and a second end, the first ends being proximal and the second ends being distal, and in that each retaining member is arranged at a corresponding second end.

Preferably, the piece is made of plastic. The invention also relates to a method of packaging goods, comprising the steps of:

supplying a plurality of lateral walls each provided with a first horizontal cross-member and a second horizontal cross each provided with an upper edge and a lower edge defining at least locally a total height of said first, respectively second, cross-member; horizontal,

supplying a base comprising a plurality of first connecting pieces providing the interface between a pair of adjacent side walls of the plurality of side walls, each first connecting piece being provided, for each side wall of said pair of adjacent side walls, a housing for receiving a portion of the corresponding first horizontal cross-member and a retaining member comprising an elastically deformable part and a retaining head, at least a first connecting piece comprises at least one stop which comes into contact with at least one side face of the base so as to allow lateral wall retention relative to the base,

- driving a pair of adjacent side walls of the plurality of side walls into one of the connecting pieces,

- arrange the goods on the base,

- Drive the other side walls in the other connecting pieces to achieve a packing box of said goods.

Advantageously in the method, said stop is previously fixed on at least one lateral face of the base by means of penetrating rods in at least one lateral face.

In particular, the method comprises a step of driving a second connecting piece onto at least a pair of adjacent sidewalls of the plurality of sidewalls. Brief description of the drawings

The box described below differs from the prior art in particular in that the connecting pieces are shaped such that a horizontal crossbar of a side wall is arranged along its entire height at the connecting piece. between the bottom of a dwelling corresponding and a retaining head of a retaining member having an elastically deformable portion.

The XYZ repository illustrated in the various figures corresponds to the repository of the cash register and makes it possible to visualize the positioning of the various coins constituting the cashier in this repository. Thus, the Z axis corresponds to a vertical axis and the XY axes define a horizontal plane. According to an embodiment illustrated in Figures 1 to 3, the body 1 comprises a plurality of side walls 2a, 2b, 2c, 2d. Each side wall is preferably provided with at least two vertical uprights 3a, 3b, a first horizontal crossmember 4a and a second horizontal crossmember 4b each having an upper edge 5a and a lower edge 5b defining at least locally the total height H of said first 4a, respectively second 4b, horizontal cross. This height H (FIG. 2) is preferably in the direction of the longitudinal axis A1 of the vertical uprights 3a, 3b. By horizontal cross member means a cross member substantially parallel to the X or Y axis or included in a plane parallel to the XY plane. In addition, the body 1 comprises a first connecting piece 6 providing the interface between a pair of adjacent side walls 2c, 2d of the plurality of side walls, said first connecting piece 6 being provided, for each side wall of said pair of adjacent side walls 2c, 2d, of a receiving housing 7 (FIGS. 4a, 4b) of a part of the corresponding first horizontal cross member 4a (that belonging to the corresponding side wall of said pair) and of a retaining member 8 comprising an elastically deformable portion 9 and a retaining head 1 0. In an assembly configuration of said box 1 (FIGS. 1 and 3), for each side wall of said pair of adjacent sidewalls 2c, 2d, the lower and upper edges 5a, 5b of the corresponding first horizontal cross member 4a are, at least in part, facing each other, and preferably in contact, one with the bottom of the corresponding housing of the first connecting piece, and the other with the corresponding retaining head 1 0 of the first connecting piece 6. Preferably, even when there is contact, there can still remain a residual game but negligible.

Preferably, the first connecting piece 6 is an angle connecting piece, that is to say that the two side walls of the pair of adjacent side walls are respectively included in secant planes in the assembly configuration of the body .

The elastically deformable portion 9 of the retaining member 8 allows a simple, manual and effective assembly by interlocking principle with deformation of the retaining member 8 during assembly and return to the natural position of the retainer 8 in assembled configuration of a connecting piece 6 with the relevant side wall.

By "facing" is meant that there may be a functional clearance between the edge (upper or lower) facing the bottom of the housing and / or the edge (upper or lower) opposite the retaining head. Preferably, the contact is such that the lower and upper edges 5a, 5b of the corresponding first horizontal cross member 4a are, at least partly, sandwiched between the bottom of the corresponding housing 7 of the first connecting piece 6 and the retaining head 1 Corresponding 0 of the first connecting piece 6. This assembly does not require forming slots beforehand in the corresponding horizontal crossbar as in the prior art. In addition, the cooperation of the retaining head with an edge (whether higher or lower) of the horizontal crosspiece considered facilitates its grip to disengage from its eyes with said edge via a force exerted so as to deform said elastically deformable portion and thus facilitate disassembly of the body.

Thus, preferably, the retaining head 10 has a prehensile shape and / or an opening for the passage of a tool such as a hook. In FIG. 4a, the retaining head 10 has a first face 11 intended to come opposite a corresponding upper or lower edge, and a second face 12 in an oblique plane with respect to the bottom 13 of the housing 7 and having a interface with said first face 1 1.

In general, the elastically deformable portion 9 is preferably formed in the extension of a lateral partition 14 of the housing 7. Preferably, the lateral partition 14 is the one disposed at the outside of the body 1 in the configuration of FIG. assembly, this allowing a better accessibility to verify the assembly or proceed to the disassembly of the body 1.

In addition, in contrast to the common interface between the first and second faces January 1, 12, each of them has an interface with the elastically deformable portion 9. This specific form allows on the one hand a good grip, and on the other hand to facilitate the deformation of the retaining member 8. In other words, it results more generally that the connecting piece 6 comprises two housings 7 extending in different directions, each housing 7 being adapted to receive a corresponding side wall of a box with which said connecting piece 6 is capable of being assembled, said part comprising, at each housing 7, a retaining member 8 comprising an elastically deformable portion 9 and a retaining head 10. Said retaining head 10 comprises a penetrating shape configured so as to come into friction along the side wall during the insertion of said side wall into the housing 7 to allow the deformation of said elastically deformable portion 9. Furthermore, the penetrating shape 12 is also such that when the side wall is engaged with the bottom 13 of the housing 7, the elastically deformable portion 9 returns to its natural position and the bottom of the housing 7 and the head of retaining cooperate to maintain, according to Z of said side wall. Said penetrating form 12 is then, in the context of the particular example described above, delimited at least in part by the second oblique face 12. It is understood from what has been said above that the retaining member 8 is arranged in such a way as to maintain a horizontal cross member of a wall of the box between the bottom of the corresponding housing and the corresponding retaining head.

According to a particular embodiment of the body 1, said first connecting piece 6 interfaces with a base 15 (Figures 1 to 3) of the body 1 and each first horizontal cross member 4a is a bottom rail. In addition, in this particular embodiment, the box 1 comprises a second connecting piece 1 6 (FIGS. 1, 2, 5, 6) comprising, for each side wall of said pair of adjacent sidewalls (2c, 2d), a housing of receiving 17 a portion of the corresponding second horizontal cross member, forming an upper horizontal cross member, and a retaining member 18 having a portion elastically deformable 19 and a retaining head 20. In the assembly configuration of said box 1, for each side wall of said pair of adjacent side walls 2c, 2d, the lower and upper edges of the second horizontal crossbar 4b of the side wall concerned are at least in part, and preferably in contact, one with the bottom 21 of the corresponding housing 17 of the second connecting piece 1 6 and the other with the retaining head 20 of the second In fact, for the same pair of adjacent side walls 2c, 2d, the two side walls 2c, 2d of said pair are connected by a first connecting piece 6 placed in the lower part of the body 1 and by a second connecting piece 1 6 placed in the upper part of the box 1 and plumb (according to Z) of the first connecting piece 6. Therefore, the first connecting piece 6 participates in the maintenance of a lower cross member of the u side walls of said pair and maintaining a lower cross member of the other side walls of said pair. By analogy, the second connecting piece 166 contributes to the maintenance of an upper cross member of one of the side walls of said pair and the maintenance of an upper cross member of the other side walls of said pair.

According to a particular embodiment, the body 1 is intended to form a parallelepiped container. For this, it comprises four side walls, four first connecting pieces 6 and four second connecting pieces 1 6. Of course, this is not limiting, and the arrangement of the side walls can also be such that the section of the body at the side walls in a plane perpendicular to the axis of the uprights can take the form of any type of polygon. In other words, the fund can have a plurality of pairs of adjacent sidewalls 2a, 2b, 2c, 2d, each pair cooperating with a corresponding first connecting piece 6 and a corresponding second connecting piece 1 6 (therefore, each side wall of the box cooperates with two first connecting pieces and two second connecting pieces 16).

According to one embodiment, the second connecting piece 1 6 has a different shape of the first connecting piece 6. This allows in particular to facilitate the assembly of the box by allowing a faster visual identification.

According to a particular embodiment of the second connecting piece 1 6 (Figure 5), each housing 17 of the second connecting piece 1 6 comprises two inner faces 22a, 22b disposed opposite opposite whose bracing E1 substantially corresponds to the thickness of the second horizontal crosspiece housed in said housing 17 of the second connecting piece 1 6. By "substantially thickness" is meant that the bracing is such that it allows to clamp the second crossbar between the two faces internally, that it allows a functional game. In particular, each housing of the second part 1 6 has an additional internal face 22c whose bracing with one of the two lateral internal faces 22a allows the housing of a portion of the corresponding second horizontal cross member and a part of a vertical upright mounted on said corresponding second horizontal cross member.

The teachings of the particular embodiment of the second connecting piece 1 6 described in the preceding paragraph can also be applied to the first connecting piece 6 as shown in Figure 4a. Preferably, the two housings 7 of the first piece 6 each have an end separated from the other housing of the first piece by a partition wall 23 (Figure 4a). This partition wall can be formed by surfaces of a rectangular or square section tube arranged in the corner of the connecting piece 6, at the boundary between the two housings 7. This ensures a better maintenance of the elements and to guarantee the parallelism of the walls of the box.

In the context of the second piece 1 6, the two housings 17 (Figures 5 and 6) each have two opposite ends open along the longitudinal axis of the horizontal cross member to be housed (X or Y axis in the particular example of the figures) . In other words, in the assembly configuration, the horizontal cross member housed in said housing 17 protrudes on either side of said housing 17 along the longitudinal axis of said horizontal beam accommodated. This allows to use less material and thus reduce manufacturing costs. According to a particular embodiment of the second piece 1 6 (Figure 6), each associated housing 17 does not have a footprint for receiving a vertical upright. In this embodiment, each housing 17 has only two opposite internal faces 22a, 22b connected by a bottom 21 forming the bracing of said inner faces 22a, 22b.

According to an improvement of the second connecting piece 16 (FIG. 7), it comprises means promoting its positioning and / or its hooking on the base 15 of another box 1 which is superimposed on a first box comprising said second piece of link 16. In other words, the second piece 1 6 may comprise (Figure 7) a base

24 provided with a first face 24a carrying the housing 17, this first face 24a comprising areas forming the bottom 21 of the housing 17, and a second face 24b (opposite the first face) and comprising adhesion elements 25 Adhesion elements

25 may be formed by points intended to penetrate into a base. According to another formulation, the second part comprises a base 24 provided with a lower face 24a at which are located the two housings 17 intended to cooperate with two side walls of said box 1 and an upper face 24b. Preferably, the upper face 24b has adhesion elements 25 at a lower face of a base 15 of an additional box stacked on said body. In addition, the first connecting piece 6 may comprise guide elements or stops 26 (Figures 4a and 4b) intended to fit a portion of an edge of the base 15 for positioning. According to an improvement, the first connecting piece 6 comprises two stops 26 extending from the lower face of the piece 6 and included in different planes, said two stops 26 being intended to come into contact with two adjacent lateral faces of the base 15 of the body. In other words, the first part 6 may comprise a base provided with an upper face at which are located the two housings intended to cooperate with two side walls of said box, and a lower face, said piece having two stops 26 extending from the lower face or beyond the lower face and included in different planes, said two stops 26 being intended to come into contact with two adjacent side faces of the base 15 of the body 1. When, for each side wall of the body, each longitudinal end of each lower horizontal cross member is housed in a corresponding housing of a corresponding connecting piece of the guide element type as described above, this also allows a maintenance mutual side walls relative to the base 15 of the body 1.

In FIG. 4b, it is noted that at least one of the abutments 26 may have a sufficiently enlarged portion 36 to reinforce the mutual maintenance of the lateral walls relative to the base 15 of the body 1. Thus, a stop may comprise an enlarged portion 36, for example at the angle of the connecting piece, then a portion of lower height extending to the end of the bottom 13 of the piece. Advantageously for the packaging envisaged below, the enlarged part comprises a height (in the z direction) of at least 2 cm, or even 3 cm, under the bottom surface of the bottom 13 of the part, and / or a length of at least minus 5 cm (in a direction x and / or y). The stops 26 may be identical in the two directions (x and y) of the connecting piece, or different.

The beveled shape of the penetrating portion 12, which descends from the outside towards the inside of the box, makes it possible to spread it outward by simply pressing the finger without having to use a tool. In general, as can be seen in FIGS. 4, 5 and 6, the two housings 7, 17 of a connecting piece (whether this is the first or the second) each comprise a first end and a second end, the first ends being proximal (and separated by a partition 23 as illustrated in the example in Figure 4a or communicating with each other as in the example of Figure 5) and the second ends being distal. In this case, each retaining member 8, 18 is arranged at a corresponding second end. In FIG. 4c, it can be seen that the abutment 26 of the connecting piece 6 comes into contact with each of the lateral faces of a corner of the base 15 over a sufficiently wide surface to allow the connection piece 6 to be held and therefore side walls with respect to the base 15 of the body 1.

This arrangement is particularly suitable for the goods packaging method which comprises the steps explained now. A first step is to supply a plurality of side walls 2a, 2b, 2c, 2d each provided with a first horizontal cross member 4a and a second horizontal cross member 4b each provided with an upper edge 5a and a lower edge 5b defining at least locally a total height H of said first, respectively second, horizontal cross.

A second step is to supply a base 15, typically a pallet, having a plurality of first connecting pieces 6 to provide the interface between a pair of adjacent side walls 2c, 2d of the plurality of side walls, each first connecting piece. 6 being provided, for each side wall of the pair of adjacent sidewalls 2c, 2d, of a housing 7 for receiving a portion of the corresponding first horizontal cross member and a retaining member 8 comprising an elastically deformable portion 9 and a retaining head 10. At least a first connecting piece 6 comprises the stop 26 which comes into contact with at least one lateral face, and preferably with two adjacent lateral faces, of the base 15.

Advantageously, the abutment 26 is fixed beforehand on at least one lateral face, and preferably with two adjacent lateral faces, of the base 15, by means of penetrating rods in the lateral face or faces. As an illustration, the penetrating rods may be screws, nails or rivets. They can in particular be made by staples of the type commonly used in the field of packaging, preferred for their ease of implementation.

The first two steps can be performed simultaneously in the same step during which a kit is supplied comprising the pre-equipped base of the lower connecting pieces, the side walls and upper link pieces.

A third step is to drive a pair of adjacent side walls 2c, 2d of the plurality of side walls in one of the connecting pieces 6 previously fixed on the base 15. The retaining member 8 on the one hand and the stop 26 on the other hand, then allow a maintenance of the side walls relative to the base 15.

Note that the stop 26 contributes to the maintenance of the side walls without necessarily being crossed by rods of nails, screws or staples. For example, in an alternative embodiment in which it is the bottom 13 which is fixed in one way or another to the base 15, the support of the stop 26 against the lateral face of the base, prevents tearing of the connecting piece 6 when a force is exerted against the corresponding side wall, from the inside to the outside. The penetrating rods in the abutment 26 along an axis perpendicular to the plane of the wall, generates an additional effect which is to oppose tearing caused by a force along an axis perpendicular to the plane of the base 15. A fourth step is to arrange the goods on the base 15 This procedure is particularly well suited to the packaging of heavy goods such as engines and / or subassemblies of vehicle body. The pair of side walls pressed in the previous step in the connecting piece 6, gives a reference to the human operator to dispose laterally the goods on the base 15. The joining of the connecting piece 6 with the base 15 , especially studied as seen above, ensures the maintenance of the side walls, even in case of friction of a commodity when it is put in place.

A fifth step is to drive the other side walls 2a, 2b in the other connecting pieces 6 to achieve the box 1 for packaging goods. A sixth step is to depress a second connecting piece 16 on at least a pair of adjacent sidewalls 2c, 2d of the plurality of sidewalls. It is possible to perform the sixth step in two stages. Firstly, it is possible to put the second connecting piece 16 on top of the adjacent side walls 2c, 2d, before disposing the goods on the base 15, so as to reinforce the cohesion of the side walls during the installation. goods. In a second step, it is possible to put other second connecting pieces 166 on top of the set of adjacent side walls 2a, 2b, 2c, 2d, after placing the goods on the base 15, so as to complete the realization of the caisse 1 in reinforcing the cohesion of the side walls. We can also put a lid on the top of the side walls at the beginning of this second time. Everything that has been said in combination with the connecting piece 6, 1 6 can be applied to the box 1 when it includes such a part 6, 1 6. Similarly, everything that has been said about the piece link 6, 1 6 in the context of the box 1 can also be applied in the context of the piece 6, 1 6 link taken separately.

Preferably, the connecting pieces are made of plastic (for example polypropylene). The use of plastic avoids cutting his finger when pressing on the penetrating portion 12 to disassemble the box. Other materials are also conceivable such as metal, wood, etc.

The side walls, and if necessary the base, are preferably made of wood.
