The invention relates to the field of packaging. The invention more particularly relates to a box having a plurality of side walls each provided with a first horizontal cross and a second horizontal cross each having an upper edge and a lower edge defining at least locally the height. total 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 of 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. Another object of the invention relates to a connecting piece particularly adapted to the body. State of the art A box generally comprises 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 is desired to be packaged / stored 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. 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, 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, viewed, 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 of the first connecting piece. Preferably, said first connecting piece interfaces with a base of the box, 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 receiving a portion of the corresponding second horizontal cross member, forming an upper horizontal cross member, and a retaining member having an elastically deformable portion and a retaining head, and in the assembly configuration of said box, for each side wall of said pair of adjacent sidewalls, the lower and upper edges of the second horizontal crossmember of the respective sidewall are at least partly facing, 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 sidewalls, each pair cooperating with a corresponding first connecting piece and a corresponding second 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 lateral internal faces disposed facing each other and whose bracing 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 comprising 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 each housing, a retaining member provided with an elastically deformable portion and a retaining head, the retaining head having a penetrating shape configured to rub along the side wall when inserting the sidewall into the housing to allow deformation of said resiliently 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 part comprises a base provided with a lower face (24a) at which are located the two housings intended to cooperate with two side walls of said body and an upper face. For example, the upper face comprises adhesion elements to a lower face of a base of an additional box stacked on said body.

BRIEF DESCRIPTION OF THE DRAWINGS Other advantages and features will become more clearly apparent from the following description of particular embodiments of the invention given by way of nonlimiting example and represented in the accompanying drawings, in which: FIG. 1 is a perspective view of a box according to an embodiment of the invention in a box assembly configuration, - Figure 2 is an exploded view of Figure 1, - Figure 3 is a side view. of the body of Figure 1 in the XZ plane, - Figure 4 illustrates a connecting part preferably intended to be arranged in a lower part of the body, - Figure 5 illustrates a connecting piece preferably intended to be arranged in a upper part of the body, - Figure 6 illustrates a variant of the part of Figure 5, - Figure 7 illustrates another view of a part according to Figure 5 or 6.

DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION 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 according to the totality of its shape. height at the connecting piece between the bottom of a corresponding housing 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 Al 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 sidewalls 2c, 2d, of a receiving housing 7 (FIG. 4) of a part of the corresponding first horizontal crosspiece 4a (that belonging to the corresponding side wall of said pair) and of a retaining member 8 comprising a elastically deformable portion 9 and a retaining head 10. In an assembly configuration of said box 1 (Figures 1 and 3), for each side wall of said pair of adjacent side walls 2c, 2d, the lower and upper edges 5a, 5b of the corresponding first horizontal crossbar 4a are, at least in part, facing, and preferably in contact, one with the bottom of the corresponding housing of the first piece of liaiso n, and the other with the corresponding retaining head 10 of the first connecting piece 6. Preferably, even when there is contact, it 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 partially sandwiched between the bottom of the corresponding housing 7 of the first connecting piece 6 and the retaining head 10 corresponding to the first connecting piece 6. This assembly does not require to form 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. 4, the retaining head 10 has a first face 11 intended to come opposite a corresponding upper or lower edge, and a second face 12 oblique with respect to the bottom 13 of the housing 7 and having an interface with said first 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 that disposed at the outside of the box 1 in the assembly configuration, this allowing better accessibility to verify the assembly or disassembly of the body 1. In addition, in contrast to the common interface between the first and second faces 11, 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 body of 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 piece 6 is capable of being assembled, said piece 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 that to come in 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. Moreover, 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 retaining head cooperate to maintain Z along 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 body 1 comprises a second connecting piece 16 (FIGS. 1, 2, 5, 6) comprising, for each side wall of said pair of adjacent side walls (2c, 2d), a receiving housing 17 of a portion of the corresponding second horizontal cross member, forming an upper horizontal cross member, and a retaining member 18 having an elastically deformable portion 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 cross member 4b of the side wall in question are at least partially facing, and preferably in contact, one with the bottom 21 of the corresponding housing 17 of the second connecting piece 16 and the other with the retaining head 20 of the second connecting piece 16. In fact, for the same pair of side walls adja 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 a second connecting piece 16 placed in the upper part of the body 1 and in the plumb (according to Z) of the first connecting piece 6. Therefore, the first connecting piece 6 contributes to the maintenance of a lower cross member of one of the side walls of said pair and the maintenance of a lower cross member of the other side walls of said pair. By analogy, the second connecting piece 16 participates in 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 16. 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 box may comprise a plurality of pairs of adjacent side walls 2a, 2b, 2c, 2d, each pair cooperating with a corresponding first connecting piece 6 and a corresponding second connecting piece 16 (hence each side wall of the box). the box cooperates with two first connecting pieces and two second connecting pieces 16). According to one embodiment, the second connecting piece 16 has a different shape from the first connecting piece 6. This in particular makes it easier to assemble the box by allowing faster visual identification. According to a particular embodiment of the second connecting piece 16 (FIG. 5), each housing 17 of the second connecting piece 16 has two internal lateral faces 22a, 22b arranged facing each other, the bridging El of which corresponds substantially to the thickness of the the second horizontal crosspiece housed in said housing 17 of the second connecting piece 16. By "substantially thickness", it is meant that the bracing is such that it allows either to clamp the second crosspiece between the two inner faces or that it authorizes a functional game. In particular, each housing of the second piece 16 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 portion of a vertical upright mounted on said corresponding second horizontal cross member. The teachings of the particular embodiment of the second connecting piece 16 described in the preceding paragraph can also be applied to the first connecting piece 6 as illustrated in FIG. 4. Preferably, the two housings 7 of the first piece 6 present each one end separated from the other housing of the first piece by a partition wall 23 (Figure 4). This makes it possible to guarantee a better maintenance of the elements and to guarantee the parallelism of the walls of the box. In the context of the second piece 16, 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 part 16 (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 16 may comprise (FIG. 7) a base 24 provided with a first face 24a carrying the housings 17, this first face 24a comprising zones forming the bottom 21 of the housings 17, and a second face 24b. (Opposite the first face) and comprising adhesion elements 25. The 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 26 (Figure 4) 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 include a base provided with an upper face at which are located the two housings intended to cooperate two side walls of said box, and a lower face, said piece having two stops 26 s extending from 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 end longitudinal axis of each lower horizontal crossbar is housed in a corresponding housing of a corresponding connecting piece of the guide element type as described above, this further allows mutual maintenance of the side walls relative to the base 15 of 1. In a general manner, as can be seen in FIGS. 4, 5 and 6, the two housings of a connecting piece 7, 17 (whether this is the first or the uxième) 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 FIG. 4 or communicating with each other as in the example of FIG. Figure 5) and the second ends being distal. In this case, each retaining member 8, 18 is arranged at a corresponding second end. All that has been said in combination with the connecting piece 6, 16 can be applied to the box 1 when it includes such a part 6, 16. Similarly, all that has been said on the connecting piece 6, 16 in the context of the box 1 can also be applied in the context of the part 6, 16 of connection taken separately. Preferably, the connecting pieces are made of plastic (for example polypropylene). Other materials are also conceivable such as metal, wood, etc.

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