Description

[Technical field]

[0001] The present invention relates to a partition plate that is attached to a returnable container or the like. [Background technology]

[0002] Returnable boxes are used as containers for storing and transporting products. These boxes use partitions to prevent products from coming into contact with other products or being mixed up with other products. Partitions are usually made of synthetic resin boards, corrugated cardboard boards, or other boards joined together in a cross shape to form a space for storing products.

[0003] In the case of a partition plate that is simply assembled by fitting together plate materials with slit grooves into each other in a cross shape, it easily comes off when lifted. For this reason, a partition plate has been developed in which a protrusion or claw is provided on the inner edge of the slit groove of one plate material, and holes are provided in the other plate material, and the protrusion or the like is fitted into the hole (see, for example, Patent Documents 1 and 2).

[0004] [Patent Document 1] Japanese Utility Model Application Publication No. 61-103310 [Patent Document 2] Japanese Patent Application Publication No. 6-92343 Summary of the Invention [Problem to be solved by the invention]

[0005] Fig. 9 shows a partition plate 300 based on the partition plate described in Patent Document 2. In the partition plate 300 shown in Fig. 9, stoppers 312 provided on horizontal partition plate 310 fit into locking grooves 325 provided on vertical partition plate 320, and stoppers 322 provided on vertical partition plate 320 fit into locking grooves 315 provided on horizontal partition plate 310, so that partition plate 300 will not come apart even when lifted. However, a partition plate having such a structure is not perfect and there is room for improvement.

[0006] In the partition plate 300 shown in Fig. 9, the vicinity of the insertion groove 317 of the horizontal partition plate 310 into which the vertical partition plate 320 fits (part A in the figure) is free in the front-to-rear direction. Therefore, when this partition plate 300 is attached to a returnable box and used, if the stored products or the like move and a force is applied to part A of the horizontal partition plate 310 in the front-to-rear direction (the direction of the arrow B in Fig. 9), this part will bend, and if an even larger force is applied, it will become deformed.

[0007] Returnable containers may be used to store and transport products of different sizes. To store larger products, it is necessary to remove some of the partitions and expand the compartments to increase the storage space. With the partition 300 shown in Fig. 9, it is possible to secure twice the storage space by attaching vertical partitions 320 to both the left and right sides as shown in Fig. 9 and removing the central vertical partition.

[0008] If partition plate 300 is used in this state, horizontal partition plate 310 has insertion groove 317 in the center, and this portion has very low strength in the front-to-rear direction. Therefore, when force is applied to this portion in the front-to-rear direction (the direction of arrow C in FIG. 9), horizontal partition plate 300 easily deforms or breaks from insertion groove 317.

[0009] An object of the present invention is to provide a partition plate which is excellent in rigidity, is difficult to deform, and does not easily deform even when a compartment is expanded. [Means for solving the problem]

[0018] In the drawings and specification, the X-axis, Y-axis, and Z-axis correspond to the X-axis, Y-axis, and Z-axis of a three-dimensional Cartesian coordinate system, and hereinafter, the description will be given assuming that the longitudinal direction of horizontal partition 10 is parallel to the X-axis, the longitudinal direction of vertical partition 50 is parallel to the Z-axis, and the short side direction of horizontal partition 10 and vertical partition 50 is parallel to the Y-axis. In addition, the direction of the arrow on the X-axis is the right, the direction of the arrow on the Y-axis is the up, and the direction of the arrow on the Z-axis is the rear or back, the longitudinal direction of horizontal partition 10 is the left-right direction, the longitudinal direction of vertical partition 50 is the front-rear direction, and the short side direction of horizontal partition 10 and vertical partition 30 is the height direction.

[0019] The partition plate 1 of the first embodiment 1 of the present invention is composed of a plurality of horizontal partition plates 10 and a plurality of vertical partition plates 50 as shown in Figure 1, and the horizontal partition plates 10 and the vertical partition plates 50 are respectively provided with mating portions 15, 55 which are mated to form compartmented chambers 150 arranged in a lattice pattern.

[0020] The horizontal partitions 10 are formed by providing fitting portions 15 into which the vertical partitions 50 are fitted in a plate material having a horizontally long rectangular shape. In the partition 1 of this embodiment, four horizontal partitions 10 are used, and the four horizontal partitions 10 have the same shape, structure, and material.

[0021] A plate material having flexibility and shape recovery is used for the horizontal partition 10. The horizontal partition 10 needs to have flexibility and shape recovery due to the structure of the fitting portion 15. Specifically, a synthetic resin plate such as a foamed resin plate is preferable. Conventional partitions are made of paper materials such as thick paper, cardboard, and corrugated cardboard, but these are not preferable for the horizontal partition 10 and vertical partition 50 of the partition 1 of this embodiment.

[0022] There are no particular limitations on the size of the horizontal partition 10, nor on the ratio of the left-right length (X direction) to the height (Y direction) of the horizontal partition 10. There is no particular limitation on the thickness of the horizontal partition 10, but making it unnecessarily thick is undesirable as it makes it difficult to bend.

[0023] The fitting portion 15 includes the slit groove 17, the hook portion 30, the locking holes 40, 41, and the recess 45, into which the vertical partition plate 50 is fitted to connect the vertical partition plates 50. For this reason, the fitting portions 15 are provided in the same number as the vertical partition plates 50 in the longitudinal direction. The fitting portions 15 are arranged from top to bottom in the order of the hook portion 30, the slit groove 17, the locking holes 40, 41, and the recess 45, and are arranged such that a part of the hook portion 30, the slit groove 17, the locking holes 40, 41, and the recess 45 are aligned in a straight line.

[0024] The slit groove 17 is a slit-shaped groove into which the vertical partition plate 50 is fitted. The width (X direction) of the slit groove 17 is approximately the same as the thickness of the vertical partition plate 50. The upper end 18 of the slit groove 17 is provided at a position slightly lower than the upper side 11 of the horizontal partition plate 10, and the lower end 19 is provided at a position half the height of the horizontal partition plate 10.

[0025] Two locking claws are provided in the height direction (Y direction) on the inner edges 21, 22 of the slit groove 17. The locking claws located at the top consist of two locking claws 25, 26, and the locking claw 25 has a downward triangular shape whose upper surface is parallel to the upper side 11 of the horizontal partition plate 10, and the locking claw 26 has an upward triangular shape whose lower surface is parallel to the upper side 11 of the horizontal partition plate 10. The two locking claws 25, 26 are arranged so that their inclined surfaces come into contact with each other and so as to block the slit groove 17.

[0026] The configuration of the locking claws 27 and 28 located at the lower part is the same as that of the locking claws 25 and 26 located at the upper part, and the locking claw 27 corresponds to the locking claw 25, and the locking claw 28 corresponds to the locking claw 26.

[0027] The hook portion 30 is located between the upper side 11 of the horizontal partition plate 10 and the upper end 18 of the slit groove 17, and opens or closes the entrance portion 20 of the slit groove 17. The hook portion 30 is a short piece formed by making an L-shaped cut from the upper side 11 of the horizontal partition plate 10, with the upper side being the upper side and the lower side 31 being connected to the upper end 18 of the slit groove 17. The tip 32 of the hook portion 30 is located on the left side of the slit groove 17.

[0028] A notch is provided in the lower side 31 of the hook portion 30 so that a downward triangular projection 35 is formed in the middle portion. The opposing portions of the projections 35 become receiving portions 36 for the projections 35, and the projections 35 and receiving portions 36 form a dovetail structure.

[0029] The locking holes 40 and 41 are holes penetrating the horizontal partition plate 10, and the locking claws 67, 68 and the locking claws 65, 66 provided on the fitting portion 55 of the vertical partition plate 50 fit into them, respectively. The locking holes 40 and 41 are sized, shaped, and positioned so that the locking claws 67, 68 and the locking claws 65, 66 fit into them with almost no gaps.

[0030] The recess 45 is a rectangular groove provided facing the lower side 12 of the horizontal partition 10, and a hook portion 70 provided in the fitting portion 55 of the vertical partition 50 fits into the recess 45. The depth (Y direction) of the recess 45 is approximately the same as the height of the hook portion 70.

[0031] The structure of the vertical partition 50 is basically the same as that of the horizontal partition 10. The material, size, dimensions, etc. of the vertical partition 50 can also be considered to be similar to those of the horizontal partition 10, so a description thereof will be omitted. Below, the structure of the vertical partition 50 will be described, focusing on the differences from the horizontal partition 10.

[0032] The fitting portion 55 of the vertical partition 50 has the same structure as the fitting portion 15 of the horizontal partition 10, and includes a slit groove 57, a hook portion 70, locking holes 80, 81, and a recess 85, into which the horizontal partition 10 is fitted to connect the horizontal partition 10. The slit groove 57, the hook portion 70, the locking holes 80, 81, and the recess 85 constituting the fitting portion 55 correspond to the slit groove 17, the hook portion 30, the locking holes 40, 41, and the recess 45 constituting the fitting portion 15 of the horizontal partition 10, and the structure, shape, dimensions, etc. of each portion are the same as those of each portion constituting the fitting portion 15 of the horizontal partition 10.

[0033] On the other hand, the positions of the parts constituting the fitting portion 55 of the vertical partition plate 50 are reversed compared to the fitting portion 15 of the horizontal partition plate 10. Therefore, the fitting portion 55 has the recessed portion 85, the locking hole 81, the locking hole 80, the slit groove 57, and the hook portion 70 arranged in this order from top to bottom, with the recessed portion 85 facing the upper side 51 of the vertical partition plate 50, and the hook portion 70 being formed by providing an L-shaped cut from the lower side 52 of the vertical partition plate 50. The recessed portion 85, the locking hole 81, the locking hole 80, the slit groove 57, and a part of the hook portion 70 are arranged in a straight line, just like the horizontal partition plate 10.

[0034] The horizontal partition plate 10 and the vertical partition plate 50 constructed as above are combined in the following manner.

[0035] In the horizontal partition plate 10 in the state shown in Fig. 2, the entrance portion 20 of the slit groove 17 is closed by the hook portion 30, and further, the middle of the slit groove 17 is closed by the locking claws 25 and 26 and the locking claws 27 and 28. Similarly, in the vertical partition plate 50 in the state shown in Fig. 4, the entrance portion 60 of the slit groove 57 is closed by the hook portion 70, and further, the middle of the slit groove 57 is closed by the locking claws 65 and 66 and the locking claws 67 and 68.

[0036] 2 and 4, the fitting portion 15 of the horizontal partition 10 and the fitting portion 55 of the vertical partition 50 cannot be fitted into each other. When fitting the fitting portion 15 of the horizontal partition 10 and the fitting portion 55 of the vertical partition 50 into each other, the slit groove 17 of the horizontal partition 10 and the slit groove 57 of the vertical partition 50 need to be opened to an extent that they can be inserted into each other.

[0037] Since the horizontal partition 10 is made of a plate material that is flexible and has shape recovery properties, the hook portion 30 can be disengaged by pushing the upper left and right portions of the fitting portion 15 of the horizontal partition 10 in the front-rear direction (the direction of the arrow D in FIG. 2) apart as shown in FIG. 3, and the entrance portion 20 of the slit groove 17 can be opened. By pushing the fitting portion 15 apart further, the locking claws 25 and 26, and the locking claws 27 and 28 will be disengaged, and the entire slit groove 17 can be opened. In addition, with the hook portion 30 of the horizontal partition 10 disengaged, the upper left and right portions of the slit groove 17 can be pushed apart in the left-right direction (the direction of the arrow E in FIG. 2), and the disengaged hook portion 30 can be further pushed apart in the up-down direction (the direction of the arrow F in FIG. 2).

[0038] Since the vertical partition plate 50 is also made of a plate material having flexibility and shape recovery, the hook portion 70 can be disengaged by pushing apart the left and right lower portions of the fitting portion 55 of the vertical partition plate 50 in the left-right direction (X-axis direction), and the entrance portion 60 of the slit groove 57 can be opened. By pushing it apart further, the locking claws 65 and 66, and the locking claws 67 and 68 will be disengaged, and the entire slit groove 57 can be opened. In addition, with the vertical partition plate 50 having the hook portion 70 disengaged, the left and right lower portions of the slit groove 57 can be pushed apart in the front-back direction (Z direction), and the disengaged hook portion 70 can be further pushed apart in the up-down direction (Y direction).

[0039] When vertical partition 50 with slit groove 57 open is inserted from above into horizontal partition 10 with slit groove 17 open, and mating portion 15 of horizontal partition 10 and mating portion 55 of vertical partition 50 are mated with each other, locking claws 65, 66 and locking claws 67, 68 of vertical partition 50 fit into locking holes 41, 40 of horizontal partition 10, and locking claws 25, 26 and locking claws 27, 28 of horizontal partition 10 fit into locking holes 81, 80 of vertical partition 50.

[0040] Furthermore, the hook portion 70 of the vertical partition 50 fits into the recess 45 of the horizontal partition 10, and the protrusion 75 of the hook portion 70 fits into the receiving portion 76, thereby closing the hook portion 70. Similarly, the hook portion 30 of the horizontal partition 10 fits into the recess 85 of the vertical partition 50, and the protrusion 35 of the hook portion 30 fits into the receiving portion 36, thereby closing the hook portion 30.

[0041] As described above, in the partition plate 1 of the first embodiment, when the horizontal partition plate 10 and the vertical partition plate 50 are fitted together, the entrance portion 20 of the slit groove 17 of the horizontal partition plate 10 and the entrance portion 60 of the slit groove 60 of the vertical partition plate 50 are closed by the hook portions 30, 70, respectively. Therefore, the vicinity of the entrance portion 20 of the slit groove 17 of the horizontal partition plate 10 will not be deformed by application of a load in the front-rear direction (the direction of the arrow G in FIG. 5). Similarly, the vicinity of the entrance portion 60 of the slit groove 57 of the vertical partition plate 50 will not be deformed by application of a load in the left-right direction (the direction of the arrow H in FIG. 5).

[0042] Fig. 6 shows an example of the partition plate 2 of the second embodiment of the present invention, where (A) is a perspective view of the partition plate 2 seen diagonally from above, and (B) is a perspective view of the partition plate 2 attached to a returnable box 200 seen diagonally from above. Fig. 7 is a perspective view of a compartment expansion partition plate 100 and a deformation prevention plate 110 used in the partition plate 2 of the second embodiment of the present invention. Here, the partition plate 2 of the second embodiment will be described based on an example, but the partition plate 2 of the second embodiment of the present invention is not limited to this example.

[0043] The basic configuration of the partition plate 2 of the second embodiment of the present invention is the same as that of the partition plate 1 of the first embodiment of the present invention, but the partition plate 2 of the second embodiment is a partition plate that extends a portion of a compartment, and includes a compartment extension partition plate 100 and a deformation prevention plate 110 in addition to a horizontal partition plate 10 and a vertical partition plate 50. The same components as those of the partition plate 1 of the first embodiment are given the same reference numerals and their explanations are omitted, and the following description will focus on the differences from the partition plate 1 of the first embodiment.

[0044] The partition plate 2 of the second embodiment includes three horizontal partition plates 10, two vertical partition plates 50 forming an outer frame, three compartment expansion partition plates 100, and three deformation prevention plates 110.

[0045] The horizontal partition 10 is made of foamed polypropylene with a length (X direction) of 476 mm, a height (Y direction) of 232 mm, and a thickness of 3 mm, and is flexible and has shape-restoring properties. The horizontal partition 10 is provided with the fitting portion 15 described in the first embodiment. The vertical partition 50 is made of foamed polypropylene with a length (Z direction) of 330 mm, a height of 232 mm, and a thickness of 3 mm, and is flexible and has shape-restoring properties. The vertical partition 50 is provided with the fitting portion 55 described in the first embodiment.

[0046] The compartment expansion partition plate 100 is a partition plate used when expanding the compartment 150, and in this embodiment, is used in place of the vertical partition plate 50. The compartment expansion partition plate 100 can also be used in place of the horizontal partition plate 10 to expand the compartment 150. This will be described later.

[0047] The compartment expansion partition plate 100 has the same structure as the vertical partition plate 50, and can be considered to be a shorter version of the vertical partition plate 50 in length (Z direction). The material of the compartment expansion partition plate 100 and the method of providing the fitting portion 55 are the same as those of the vertical partition plate 50. The compartment expansion partition plate 100 of this embodiment has a length (Z direction) of 182 mm, and is provided with two fitting portions 55 in the length direction (Z direction). The length L (Z direction) of the protruding portion 104 protruding from the fitting portion 55 toward the end portion 102 is 17 mm.

[0048] In the partition plate 2 of this embodiment, a compartment 160 with double the storage volume is obtained by using the compartment expansion partition plate 100. As can be seen from Fig. 6, for the compartment 160, it is preferable that the length L of the protruding portion 104 is short. On the other hand, the protruding portion 104 should not be extremely short in order to increase the rigidity of the partition plate 2 after it is fitted with the horizontal partition plate 10 and contribute to preventing deformation.

[0049] The deformation prevention plate 110 is fitted into the fitting portion 15 of the horizontal partition plate 10 into which the vertical partition plate 50 removed to expand the partition chamber 150 was fitted and into which the partition chamber expansion partition plate 100 does not fit and which becomes free, thereby reinforcing this portion and preventing deformation.

[0050] The deformation prevention plate 110 has the same structure as the vertical partition plate 50, but is shorter in the length direction (Z direction) of the vertical partition plate 50 and is provided with one fitting portion 55. The material of the deformation prevention plate 110 and the method of providing the fitting portion 55 are the same as those of the vertical partition plate 50. The deformation prevention plate 110 of this embodiment has a length (Z direction) of 35 mm.

[0051] The partition plate 2 of the second embodiment described above includes the compartment expansion partition plate 100, so that the compartment can be easily expanded. The compartment expansion partition plate 100 closes the entrance portion 60 of the slit groove 57 in the same manner as the vertical partition plate 50. hook part 70, a load is applied in the left and right direction (X direction) to the vicinity of the inlet portion 60 of the slit groove 57. tooIn addition, since the compartment expansion partition plate 100 has a protruding portion 104 adjacent to the fitting portion 55, the rigidity of the partition plate 2 is increased, and the partition plate 2 and the compartment 160 are prevented from being deformed.

[0052] Furthermore, since the partition plate 2 of the second embodiment is equipped with a deformation prevention plate 110, the fitting portion 15 of the horizontal partition plate 10 which becomes free when the compartment expansion partition plate 100 is used instead of the vertical partition plate 50 is also reinforced, thereby preventing deformation.

[0053] Fig. 8 is a plan view showing another embodiment of the partition plate of the present invention. The same components as those of the partition plates 1 and 2 shown in the first and second embodiments shown in Figs. 1 to 7 are given the same reference numerals and their explanations are omitted. Fig. 8(A) corresponds to the partition plate 1 of the first embodiment, and Fig. 8(B) corresponds to the partition plate 2 of the second embodiment.

[0054] Fig. 8(C) shows partition plate 3 in which compartment expansion partition plates 100 are used instead of the two horizontal partition plates 10 in partition plate 1 in Fig. 8(A) to expand the compartment in the front-to-rear direction. As can be seen from Fig. 8(C), compartment expansion partition plates 100 of different lengths can be used for partition plate 3. Fig. 8(D) shows partition plate 4 in which two left-right compartment expansion partition plates 100 and one front-to-rear compartment expansion partition plate 100 are used in partition plate 1 in Fig. 8(A) to expand the compartment in the left-right and front-to-rear directions.

[0055] Fig. 8(E) shows a partition plate 5 in which the second and third horizontal partition plates 10 from the front of the four horizontal partition plates 10 have been removed, and further the second and fourth vertical partition plates 50 from the left of the five vertical partition plates 50 have been removed from the partition plate 1 in Fig. 8(A). The size of the compartment of such a partition plate 5 is six times the size of the compartment of the partition plate 1 in Fig. 8(A).

[0056] The partition plates 2, 3, 4, and 5 shown in Figures 8(B) to (E) are the same as the partition plate 2 of the second embodiment in that a deformation prevention plate 110 is attached to the fitting portion 55 and / or fitting portion 15 that is opened by removing the horizontal partition plate 10 and / or the vertical partition plate 50.

[0057] As explained above using the first and second embodiments, and also the embodiment shown in Figure 8, the partition plate of the present invention has a hook portion 30 that blocks the entrance portion 20 of the slit groove 17 of the horizontal partition plate 10, and a hook portion 70 that blocks the entrance portion 60 of the slit groove 57 of the vertical partition plate 50, and therefore has superior rigidity and is less likely to deform than conventional partition plates.

[0058] Furthermore, in the partition plate according to the present invention, the horizontal partition plate 10 and the vertical partition plate 50 are detachable, and further, the compartment expansion partition plate 100 can be used in place of the removed horizontal partition plate 10 and / or vertical partition plate 50, so that the size of the compartment can be changed in various ways. By attaching a deformation prevention plate 110 to the fitting portion 15 and / or fitting portion 55 that becomes free by using the compartment expansion partition plate 100 in place of the horizontal partition plate 10 and / or vertical partition plate 50, it is possible to provide a partition plate that does not easily deform even when the compartment is expanded.

[0059] The above describes the partition plate of the present invention using several embodiments, but the partition plate of the present invention is not limited to the above embodiments and can be modified and used within the scope that does not change the gist of the present invention.

[0060] The partition plate in the above embodiment has locking claws on the inner edges of both sides of the slit groove, but the locking claws may be provided on the inner edge of either one of the slit grooves. The shape of the locking claws may also be a semicircular shape or other shape other than a triangle. The partition plate in the above embodiment has locking claws in two locations above and below the slit groove, but the locking claws may be in one location, or in three or more locations. The shape, number, and position of the locking holes may be determined to correspond to the locking claws.
