DESCRIPTION

Stackable container device

The present invention relates to a stackable container device.

More particularly, the invention relates to a stackable container device that includes a platform having a horizontal bottom, two longitudinal walls and two solid transverse walls including the container device, in addition, two transverse curbs that are oriented horizontally on the side interior of the platform determining, with a horizontal upper edge of the walls of the platform at the corners where the longitudinal and transverse walls join, a support for stacking.

An example of this type of device is known from EP0870689 which discloses the use of curbs connected with folds to the transverse walls and fixed to the ends of the longitudinal walls. The curbs are integrated into the platform. The transverse end plates can be slid below the curbs. Each plate has three sheets, of which a central sheet is in correspondence with a central part of the corresponding transverse wall and the lateral sheets are inclined below the curbs, the central sheet towards the longitudinal walls. Above and below the side blades are cut at the bias to fit the upper angles in the form of a chamfer of the platform. The assembly of these side plates of the end is relatively complex since it is necessary to control well the dimensional dispersions of both the platform and the aforementioned plates, although the chamfers of the platform and the bias cuts of the transverse plates can facilitate the centering of the irons On the other hand, in addition to the need to control insertion games well, sliding the plates under the curbs is an operation that can be delicate to be automated. In effect, curbs may represent an obstacle to the insertion of the plates. Other container devices of documents WO 88/02724, GB 09467, FR 1 358 881 and US 2010/247272 are known.

The present invention aims especially to improve existing solutions and / or propose alternatives.

In addition to the drawbacks expressed above in relation to one of the solutions of EP0870689, other drawbacks can be taken into account when it comes to proposing container devices of strong mechanical strength for stacking. It is good to reinforce the platforms for stacking, in particular for products such as fruits and relatively dense legumes that increase the inconveniences during vertical stacking of said platforms, but in addition it is not necessary to complicate their structure or their mode of conformation too much.

Indeed, the object of the invention is a stackable container device according to claim 1.

In various embodiments of the container device according to the invention, one or the other of the following arrangements may also be used:

- the fixing face extends vertically downwards;

- the face of the curbs is attached to the corresponding transverse wall forming part of the continuity of the material of this transverse wall and is folded perpendicularly with respect to this transverse wall;

- the fixing face is fixed to the inner face of the corresponding transverse wall;

- each reinforcement device is added to the platform and has, on the one hand, a main face that extends with respect to the set of the corresponding transverse wall of the platform, from the bottom of the platform and to the upper edge of the platform. platform and, on the other hand, its intermediate face which is attached from above to the main face as well as its fixing face that is fixed to the inner face of the main face;

- each added reinforcement device includes two lateral tabs vertically attached to the free lateral ends of the main face and located against an inner face of the longitudinal walls of the platform;

- the two lateral tabs extend vertically from the bottom of the platform and to the upper edge of the platform;

- Each reinforcement device added is made of cardboard of a different thickness than the thickness of the platform that receives it.

In the embodiment represented as an example in the figures, the container device 10 is sensitive and basically a parallelepiped rectangle having its platform 12 comprising a horizontal rectangular bottom 12D whose length determines the longitudinal direction described in the present description and the width Corresponds to the transverse direction described in this description. The height of the platform is, for example, about one third of the length of the platform. The container device therefore serves as a reference for defining the longitudinal direction and the transverse direction.

Such platform 12 has usual dimensions to typically contain fruits or legumes. For example, a platform like this may contain melons. To transport melons, when container devices are stacked, their resistance to vertical compression must be important as melons are relatively dense and heavy products. In fact, the platforms thus stacked, for example, on a pallet must bear, in particular by those under the stack, a very important mass taking into account the mass of the platforms filled and arranged up to the top of the stack.

The container devices 10 according to the invention are stackable and are intended for this use, with the drawbacks explained above. Each container device 10 has its platform 12 that includes two longitudinal walls 12L and two transverse walls 12T that are solid. These transverse walls 12T are substantially rectangular and are solid being vertically joined to the longitudinal walls 12L and horizontally to the bottom wall 12D. The platform 12 is made of cardboard with parallel grooves that are arranged longitudinally. In the transverse walls 12T, the grooves are aligned vertically for good resistance to vertical compression of the transverse walls. The reinforcing devices 13 are also made of cardboard with parallel grooves that are arranged parallel to the grooves of the platform.

The two transverse walls 12T of the platform are each provided with at least one upper spike 16 of stacking that protrudes from the horizontal upper edge of the transverse walls. In practice, the dimensions of the pins 16 are standardized, as are the locations of these pins. In this way, the different manufacturers of platforms intended to be stacked use these dimensions and these standard type locations. The platform 12 includes a notch 18 made at the junction of the bottom 12D of the platform with each transverse wall 12T for receiving a spike 16 of the corresponding stack when the platforms are stacked.

The platform 12 has its longitudinal walls 12L that determine a vertical recess 12V on a part of its length and on a part of the height of the platform, centered in the middle of the length of this longitudinal wall. Each vertical recess 12V is open with a widening at the top of the platform, above a central area of the lower part of the longitudinal wall. Such a 12V recess is of the classic type and does not deserve to be detailed. On the other hand, the longitudinal walls 12L are equipped at the top of their recess 12V with an upper flap 12R that does not deserve to be described in more detail.

Platform 12 comes from an initially flat die as shown in Figure 2. Each longitudinal wall 12L includes an external side wall 22 that goes over the entire length of the platform and over the entire height of the platform except in the central part of the upper part of the outer side wall that determines the vertical recess. In addition, each longitudinal wall 12L includes two interior panels 24 that are initially added to each lateral end of each transverse wall 12T. The union of each inner panel 24 with its transverse walls 12T is done by folding along a vertical folding line 26. Figure 2 shows very well each folding line 26 on the initial plate that determines the cardboard flank that serves as the basis for The construction of the platform. Each inner panel 24 is on a part of the length of the corresponding longitudinal wall 12L and on the entire height of this longitudinal wall at its end areas that are arranged longitudinally on each side of the central area at the bottom of the wall longitudinal.

At each end of the platform, there is an upper edge 28 that is horizontal and that is determined by the upper faces of the platform walls at their connecting corners of the longitudinal and transverse walls. These corners have the vertical folding lines 26. Each upper edge 28 defines a support for the stacking in height of the end areas of the longitudinal walls 12L and in height of the transverse walls 12T in the center of which the pins 28 constitute an interruption of this upper edge.

The container device further comprises two transverse curbs 30 that are oriented substantially horizontally, determining, with the upper horizontal edge 28 of the platform walls at their connecting corners of the longitudinal and transverse walls, a stacking support. The transverse curbs 30 are adjacent to the upper ends of the transverse walls 12T, these upper faces constituting portions of the upper edge 28 of the platform. The transverse curbs 30 are oriented inside the platform from the aforementioned upper faces. The transverse curbs 30 may be slightly inclined a few degrees down and into the platform.

The platform 12 is configured from a die by folding the outer side walls 22 along a horizontal folding axis such that each outer side wall 22 is carried perpendicularly to the bottom 12D of the platform. Each inner panel 24 is folded perpendicularly to its transverse wall 12T, by folding

according to the corresponding folding line 26. Finally, each transverse wall 12T equipped with its inner panels 24 folded at right angles is folded along a horizontal folding axis in such a way that it carries each transverse wall 12T perpendicularly to the bottom 12D of the platform while the inner panels 24 slide parallel to the side walls 22, along the inner faces of these walls. The inner panels 24 are glued to the corresponding end areas of the outer side walls 22. Such bonding is classic. The forming process of the platform 12 can be carried out using a classic forming machine.

In general, in correspondence with each solid transverse wall 12T of the platform, each of the reinforcement devices 13 is provided, on the one hand, with a face 30 extending at right angles to the corresponding transverse wall 12T constituting the corresponding curb and, on the other hand, two folded faces connecting the curb face 30 within the container device, thus stabilizing this curb horizontally at the level of the horizontal upper edge 28. These folded faces include an intermediate face 37 which extends below the curb and a fixing face 39 that extends vertically from the intermediate face being stable relative to the corresponding transverse wall.

In the first embodiment, as shown in Figure 1 to Figure 6, the two reinforcing devices 13 are pieces of cardboard that are added to the platform. Each reinforcing device 13 intended to be added to the platform 12 has, on the one hand, a main face 33 and, on the other hand, attached at the top to the main face, the curb 30 which is constituted by a face folded at right angles With respect to the main face.

Each added reinforcement device 13 includes a recess 35 for receiving, when the container devices 10 are stacked, of the corresponding stacking pin 16 belonging to the adjacent container device 10 below the reinforcement device 13 considered. This pin 16, by collaborating by means of its hook in the recess 35 and in the corresponding notch 18 of the platform, allows the stacking of the stackable container devices.

Each reinforcement device 13 has its connecting members which, in addition to the union with the main face 33, allow the curb to be fixed within the container device by fixing the curb horizontally. The connecting members allow the curb faces 30 to be locked horizontally in relation to the rest of the container device, in order to avoid the sinking of the curbs when the devices are stacked.

These additional joining organs have the same general principle for different embodiments.

In the first illustrated embodiment of Figure 1 to Figure 6, each added reinforcement device 13 includes, in its connecting members, the two folded connecting faces of the curb part. On these two faces, on the one hand, the intermediate face 37 is intended to extend below the curb 30 and, on the other hand, the fixing face 39 is intended to extend downwardly from the intermediate face 37 being fixed to the internal face of the main face 33. When the reinforcing device 13 is on the platform 12, the intermediate face 37 extends inclined below the curb face 30, being oriented, from a free end of the curb face on the inner side of the platform, on the one hand, towards the corresponding main face 33 and, on the other hand, towards the bottom 12D of the platform.

The operation of the container device 10 according to the first embodiment is already deduced in part from the description above and will now be detailed.

In the first phase of the assembly example, as shown in Figure 3, the reinforcement devices 13 are positioned close to their assembly on the platform 12. The reinforcement devices 13 are presented vertically, above and substantially in parallel planes to the 12T transverse walls. The reinforcing devices 13 are then prepared to be lowered vertically in the direction of the bottom wall 12D of the platform.

In the second phase of the assembly example, as shown in Figure 4, at the beginning of its assembly on the platform, the reinforcement devices 13 are positioned at the insertion with the platform 12. They are lowered substantially parallel to the wall corresponding 12T transverse and are then approximated by combined horizontal translation, where appropriate, with a pivot around a horizontal axis, for sticking to the internal face of its transverse wall. In this way, each reinforcement device 13 is added to the platform 12, its main face 33 having extended with respect to the corresponding transverse wall assembly 12T of the platform, from the bottom 12D of the platform and to the upper edge 28 of the platform. Advantageously, the insertion movements are relatively simple and allow a mechanization by means of a machine that can then be of robust design and yet not very complex in its architecture and economical manufacturing.

In the third phase of the assembly example, the height of the reinforcement devices is transformed. The reinforcement devices are folded for shaping in the direction inside the platform.

Figure 5 shows the beginning of the folding that allows the formation of the curbs 30. This folding is made according to pivots of the transverse and horizontal axes. The curb 30 pivots with respect to the upper end of the main face 33, to achieve a horizontal orientation. The intermediate face 37 pivots with respect to the free end of the curb face 30, unlike the main face, so that it is oriented inclined under the curb. The fixing face 39 is pivoted with respect to the free end of the intermediate face 37, unlike the curb 30, to be oriented vertically below said curb being directed downwards and positioned against the main face 33 by sticking.

Thus, as shown in Figure 6, the assembly of the platform 12 and the reinforcement devices 13 is finished. To recap, the face of the curb 30 is folded at a right angle, being horizontal and directed towards the inside of the platform. The face of the curb 30 is cantilevered at a distance from the bottom 12D, level horizontally with the upper edge 28 of the corresponding corners of the platform.

Continuing with the recapitulation, the intermediate face 37 extends below the curb 30 and the fixing face 39 extends downwardly from the intermediate face 37 being fixed to the inner face of the main face. The intermediate face 37 is inclined below the curb face being oriented, from a free end of the curb face, inside the platform, on the one hand, towards the corresponding main face and, on the other hand, towards the bottom of the platform. It serves, in this way, as a wild boar so that the curb is stiffened throughout its length and retains its horizontal orientation. The fixing face 39 stabilizes together in its position. To save material, the fixing face is of reduced height as shown in the figures, the glue allows a good solidity of the assembly even though the lower part of the fixing face 39 does not rest on the bottom of the platform.

Various advantages can arise from the platform reinforcement solution using the reinforcement device 13 with its curb 30 resistant to vertical sinking. The curbs 30 are stabilized allowing good resistance during stacking of the container devices.

In addition, with the reinforcement devices 13 added, the main faces 33 provide an improvement in the vertical compressive strength of the container device, by folding the transverse walls of the platform.

Advantageously, the dimensional dispersions of both the platform and the reinforcement device are easy to manage to have a stackable container device that is solid and comfortable to assemble. In addition, the geometry of the reinforcement device favors the absence of loss of material so that falls are minimized.

Advantageously, the geometry of the reinforcement device, by integrating a curb, allows this curb to occupy little space inside the platform. Indeed, this curb is solid without being too bulky and without being complex to keep solidly on the platform.

Advantageously, each added reinforcement device 13 can have a thickness different from the thickness of the platform 12 that receives it. In this way, to have a container device that has good vertical compression resistance characteristics, it is possible to use a base platform that has a cardboard, for example, relatively thin and simple grooves and choose to use an added reinforcement device 13 which is thicker and, for example, provided with double channels.

Advantageously, the reinforcement devices 13 do not disturb the good use of the draft pins 16 for stacking.

The container device can be shaped using, on the one hand, a standard forming machine for the platform and, on the other hand, a specific forming machine for the added reinforcement device. The same machine can be added to form the added reinforcement and assemble it on the platform.

As a variant of the assembly, the added reinforcement device may have its curb preformed to the assembly on the platform. The added reinforcement device can be assembled on the corresponding transverse wall of the platform before the platform is formed, this platform being formed when the reinforcement devices are already added on the die to be formed.

The assembly of the reinforcement devices on the platform can be carried out quite flexibly, knowing that the platform can be of the standard type. For example, the main face of each reinforcement device can be lowered substantially vertically, more or less parallel to the corresponding transverse wall of the platform, and then when the bottom of the main face is close to the bottom or touch it, the reinforcing device can be applied laterally against the transverse wall by sticking.

The mechanization of the assembly can be modular, preserving, for example, an existing platform forming machine for a standard platform. This mechanization can be little complex due to the simple assembly movements of the reinforcement device on the platform.

In the variant of the first embodiment as shown in FIG. 7 to FIG. 11, each added reinforcement device 13 comprises, in addition to the configuration described above, two lateral tabs 43 that vertically join the free lateral ends of the main face 33. Each tongue 43 is against an inner face of the longitudinal walls of the platform. A vertical fold 46 is present at the intersection of the main face 33 and each side tongue. The two lateral tabs 43 extend vertically from the bottom 12D of the platform 12 and to the upper edge 28 of the platform.

In the first phase of the assembly example, as shown in FIG. 8, the reinforcement devices 13 are positioned close for assembly to the platform 12, after folding the side tabs 43 perpendicularly to their adjacent main face. The reinforcing devices 13 are presented vertically, above and substantially in the planes parallel to the transverse walls 12T having the tabs 43 on the inner side of the platform. The reinforcement devices 13 are then prepared to be lowered vertically in the direction of the bottom wall 12D of the platform, the tabs 43 then sliding against the inner faces of the inner panels 24 belonging to the longitudinal walls 12L of the platform.

The rest of the assembly operations are carried out with the same principle as described above.

In the second phase of the assembly, at the beginning of its assembly on the platform, the reinforcement devices 13 are positioned in the insert with the platform 12. They are lowered substantially parallel to the corresponding transverse wall 12T and then when the lower part of the main faces is near the bottom 12D, the reinforcement devices approach with a combined horizontal translation, if necessary, with a pivoted around a horizontal axis for bonding to the internal face of its transverse wall. With the same principle as explained above, each reinforcement device 13 joins the platform 12 with its main face 33 extending with respect to the corresponding transverse wall assembly 12T of the platform.

Figure 9 corresponds to Figure 4 and shows the said reinforcements 13 at the beginning of the assembly to the platform. Advantageously, the insertion movements are still relatively simple. The side tabs 43 triple the thickness of the end zones at the corners of the container device.

The side tabs 43 may be glued to the longitudinal walls. If the gluing of the tabs is prior to the insertion of the reinforcement device 13 in the platform 12, the lowering of said reinforcement is carried out with the tabs 43 pressed against its main face. If the gluing of the tongues is subsequent to the insertion of the reinforcement device 13 into the platform 12, during gluing, the tongues 43 are pressed towards their main face pivoting on the platform according to the fold 46. The bonding of the tongues 43 is It carries out the curbs 30 towards its horizontal working position.

In the third phase of the assembly example, the reinforcement devices 13 have their high part folded with the conformation towards the inside of the platform. Figure 10 corresponds to Figure 5 and shows the beginning of the folding that allows the formation of the curbs 30. The folding is done according to the same pivots of the transverse and horizontal axes as those described above. The curb 30 pivots to be in a horizontal orientation. The intermediate face 37 is pivoted with respect to the free end of the curb face 30, to end up being inclined under the curb, passing between the side tabs 43. The fixing face 39 is pivoted with respect to the free end of the intermediate face 37, passing between the lateral tabs 43 to end up being oriented vertically below said curb being directed downwards and positioned against the main face 33 by sticking.

Thus, as shown in Figure 11, the assembly of the platform 12 and the reinforcement devices 13 is finished. To recap, the face of the curb 30 is folded at a right angle, being horizontal and directed towards the inside of the platform. The side of the curb 30 is cantilevered at a distance from the bottom 12D, horizontally leveled with, on the one hand, the upper face of the side tabs 43 and, on the other hand, with the upper edge 28 of the corresponding corners of the platform.

A second embodiment of the container device 10 is shown from Figure 12 to Figure 15, this container device being different from the first embodiment in some features. The reinforcement devices 13 are different since they have the curb faces integrated with the rest of the platform, without being added.

Thus, according to this second embodiment, the face of the curb 30 is directly attached to the corresponding transverse wall 12T as if it were a continuity of material of this transverse wall and being folded perpendicularly with respect to this transverse wall. The fixing face 39 is fixed to the inner face of the corresponding transverse wall 12T.

For the second embodiment of the container device, the assembly operations for the assembly of the reinforcement devices 13 on the platform 12 differ little from the operations described in relation to the first embodiment. The differences are described below.

In any beginning of assembly, as shown in Figure 13, it is a question of forming the longitudinal walls and the transverse walls, the latter bearing their curb faces 30, their intermediate faces 37 and their fixing faces 39.

Figure 14 corresponds to Figure 5 and Figure 10 for folding the curb face 30 for pivoting along the upper edge of the corresponding transverse wall 12T. The intermediate face 37 and the fixing face 39 are also folded by pivoting according to the horizontal folding axes.

As shown in Figure 15, the faces of the curb 30 are folded down to be horizontal on the inside of the platform. The intermediate face 37 is inclined below the curb face 30, as in the cases explained above. The fixing face 39 is glued on the inner face of the corresponding transverse wall 12T, extending downwards, in the direction of the bottom 12D of the platform.

In another variant shown in Fig. 16, with respect to the first embodiment, the fixing face 39 is still glued on the inner face of the main face 33, but extends upward, below the root of the curb face .

In this variant, the curb face 30, the intermediate face 37 and the fixing face 39 are folded before the transverse walls and the longitudinal walls are folded for shaping.

In a variant not shown on the basis of the second embodiment, the curb face 30, the intermediate face 37 and the fixing face 39 are directly connected to the corresponding transverse wall 12T but the fixing face is folded with a fixation towards Up rather than down.

In a more general way, the outer side walls can have a horizontal top, located below the high level of the inner panels participating in the determination of the upper edge of the platform.

The advantages of solidity and ease of use of the container device are substantially the same for the different embodiments.

In a variant not shown, the upper stacking pins for stacking are placed differently, for example, being two in number at the top of the transverse walls. The same happens with the locations of the notches and recesses.
