Abstract

PROBLEM TO BE SOLVED: To prevent a partition from being detached from an upper bottom board when work of setting a partitioning material to a box is performed. SOLUTION: A partitioning material S has a structure that partitioning walls 4 of a partition 2 are inserted into elongated holes 3 in an upper bottom board 1 from the underside thereof and that the partitioning walls 4 are projected upward from the elongated holes 3. In this partitioning material S, each partitioning wall 4 is formed into a tapered shape that the width of an upper end part of the partitioning wall becomes smaller than the width of the elongated hole and that the width of a lower end part thereof becomes larger than the width of the elongated hole, and a notch 5 which is engaged with each edge of the elongated holes 3 is provided at a base portion of each of both side edges of the partitioning wall.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cardboard partition member used for storing a tube of paint in a box.

[0002]

2. Description of the Related Art For example, when packing paint tubes in a box, as shown in FIG. 13, a cardboard partitioning material S is provided inside a box A including a body b and a lid c. This partition material S is
An upper bottom plate 1 laid on the bottom wall of the body b and a partition plate 2 attached to the upper bottom plate 1.
And the partition plate 2 is folded into a fold to form a double partition wall 4.
The width of the partition wall 4 is set to be slightly smaller than the length of the long hole 3 in the vertical direction, the partition plate 2 is overlapped on the lower surface of the upper bottom plate 1, and the partition wall 4 is moved upward from the long hole 3. It has a protruding configuration.

[0003]

However, with the above-described partitioning material, the partitioning plate may fall off from the upper bottom plate when it is set in a box, and the work efficiency may be reduced.

[0004] Therefore, an object of the present invention is to prevent a partition plate from falling off from an upper bottom plate at the time of setting work on a box.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, according to the present invention, a partition wall is engaged with a peripheral edge of a long hole of an upper bottom plate to prevent the partition plate from falling off from the upper bottom plate. is there.

[0006]

Embodiments of the present invention will be described below with reference to the accompanying drawings. Parts corresponding to the respective parts of the conventional example shown in FIG.

FIGS. 1 to 4 show a first embodiment of the present invention. The partition wall 4 of the partition material S has an elongated hole 3 at the upper end.
Is formed in a tapered shape having a width of a lower end portion larger than the length of the long hole 3, and a notch 5 for engaging with an end edge of the long hole 3 is provided at a base of both side edges thereof.

When assembling the partition material S, the width of the upper end of the partition wall 4 is smaller than the length of the slot 3, so that the partition wall 4 can be easily inserted into the slot 3. Thereafter, as the partition wall 4 is pushed into the slot 3, both side edges of the partition wall 4 come into contact with the edges of the slot 3, and these are elastically compressed with each other.
When the is inserted up to the base, this compression is released and the cut 5 engages the edge of the slot 3. This engagement prevents the partition plate 2 from falling off the upper bottom plate 1.

FIGS. 5 to 8 show a second embodiment of the present invention. In the partition material S, a tongue piece 6 is formed by cutting the partition wall 4 upward from its lower end, and the tip of the tongue piece 6 protrudes due to the rebound of the top fold of the partition wall 4 to form the elongated hole 3. Of the partition plate 2 from the upper bottom plate 1 is prevented.

FIGS. 9 to 12 show a third embodiment of the present invention. In the partition material S, an insertion hole 7 is formed along the base end of the partition wall 4, and a protruding piece 8 is formed on a side edge of the elongated hole 3, and the protruding piece 8 repels a top fold of the partition wall 4. This prevents the partition plate 2 from being inserted into the insertion hole 7 and falling off from the upper bottom plate 1.

[0011]

As described above, according to the present invention, the partition wall of the partition plate is inserted into the long hole of the upper bottom plate from below,
In a partition material with a partition wall protruding upward from the long hole, the partition wall is engaged with the periphery of the long hole to prevent the partition plate from falling off from the upper bottom plate. Can do well.
