Description

[Detailed description of the invention] [Field of industrial application] This invention relates to a connecting box that stores, transports and stores items in a connected state and can be divided as needed.

[Conventional technology]

As shown in FIGS. 5 to 7, a conventional connection box of this type is described in Japanese Utility Model Publication No. 57-49704. This connecting box has bottom walls 33 extending in opposite directions on each lower edge of a double intermediate wall 32 having a connecting part 31 on the upper edge, and a side edge of each bottom wall 33 with an intermediate wall. The opposing side walls 34 also have an outer edge 35 connected to both ends, an inner end wall 36 connected to the upper edge of each outer end wall 35, and each intermediate wall 32 has a folded piece symmetrically formed at one end. A horizontally long folding piece 38 is provided at the other end of each side wall 3, and the part that is folded back in the opposite direction from the middle is located at the connecting part of the box body.
A folding piece 39 that is folded in between a double outer end wall 35 and an inner end wall 36 is provided on both ends of the folding member 4, respectively.

Note that 40 is a partition frame which is a separate member.

When assembling this connection box, as shown in FIG. 6, the horizontally elongated folding piece 38, which is once folded inward and engaged with the opposing folding piece 39 through a notch, is folded back halfway in the opposite direction to form the box. By being held by the outer end wall 35 and the inner end wall 36 together with the folding pieces 37 and 39 which are located at the connecting part of the body and engage with each other through cuts, the legs of both boxes are prevented from opening.

[Problem that the invention attempts to solve]

However, in this known connecting box, no locking means is provided at the tip of the folded part of the folding piece 38 that spans both box bodies, so the free end tends to shift and move, making it difficult to put items into each box body. When a heavy weight is applied to the product, it tends to wobble during handling or become twisted from the connecting part.

[Means for solving problems]

In order to solve the above-mentioned problems, this invention provides first notches that open downward in the folding pieces that protrude from both ends of each side wall, that is, the first folding pieces, and also provides protrusions at both ends of the intermediate wall. A second notch that opens upward and fits into the first notch is provided near the folding point and near the tip of one of the provided folding pieces, that is, the second folding piece.

[Effect]

According to this invention, the folded second folding piece is firmly connected to the first folding piece protruding from the side walls of both boxes, so that it does not wobble during handling even when the weight of the item is increased. This prevents the connector from twisting or twisting from the connecting portion.

〔Example〕

1 to 4 show examples of this invention. This connection box has a connection part 1 on the upper edge.
A rectangular bottom wall 3 extending in mutually opposite directions is connected to each lower edge of the double intermediate wall 2 having a side edge. Outer end walls 5 are connected to each other, an inner end wall 7 is connected to the upper edge of each outer end wall via two fold lines 6, and first folding pieces 8 are protruded from both ends of each side wall. A second folding piece 9 is provided at the end of the intermediate wall 2 and engages with one of the first folding pieces 8, and also folds back halfway in the opposite direction and engages with the other first folding piece 8 facing the other side. and a third folding piece having approximately the same shape as this second folding piece.
The folding pieces 10 and the folding pieces 10 are arranged to protrude alternately.

The first folding piece 8 is provided with a first notch 11 that opens downward at its tip. The second folding piece 9 is provided with upwardly opened second notches 12 and 13 which fit into the first notch 11 at the folded portion and at the tip thereof with a required spacing l.

The length of each of the notches 11, 12, 13 is 1/2 of the height of each folding piece 8, 9, and a second notch that opens upward is fitted into a first notch that opens downward. When aligned, the folded pieces will be at the same height and will intersect perfectly.

The second folding piece 9 is provided with a fold line 14 at a position along the second notch 12 of the folded part, and also at a position corresponding to the connecting part when the part beyond this fold line 14 is folded back. Perforated break line 15
is engraved.

When the second folding piece 9 is assembled with the box and facing the first folding piece 8, the second notch 12 coincides with the first notch 11 at the fold line 14, and the second notch 12 coincides with the first notch 11. When folded back, the second notch 13 at the tip is formed to match the first notch 11 of the opposing first folding piece 8.

When assembling the connecting box, as shown in Figure 2, use the unfolded punched blank A (see Figure 3), bend it from each fold line, and attach the intermediate wall, side wall, and outer wall around the bottom wall. While erecting the end wall, the first
folding piece 8, second folding piece 9 and third folding piece 1
0 respectively, fit the second notch 12 of the second folding piece 9 into the first notch 11 of the first folding piece 8, and fold it back in the opposite direction from the crease line 14, and then The second notch 13 is fitted into the first notch 11 of the folding piece 8 to connect both of the first folding pieces 8, 8, and finally, each of these folding pieces are collectively connected to the outer end wall. It is held by the inner end wall.

Note that this connecting box can be easily separated into two parts by tearing the connecting part 1 with the cut in the center and dividing the folded part of the second folding piece that spans the connecting part from the breaking line 15.
Can be divided into individual boxes.

〔effect〕

As listed above, the connection box according to this invention is
The second folding piece that has engaged with one of the first folding pieces is folded back halfway in the opposite direction and is cross-engaged with the other first folding piece facing each other to firmly connect both of the first folding pieces. It is stable, does not wobble during handling, does not twist from the connection part, and is easy to separate even if the weight is increased by putting items in both boxes. effective.
