Description

[Detailed Description of the Invention] The present invention relates to a cardboard box suitable for transporting and selling mainly fruits such as strawberries and grapes, relatively high-quality fruits and vegetables, and marine products.

Because these relatively high-grade fruits, vegetables, and marine products have high selling prices, it is desirable to sell them in small units, but on the other hand, when transporting them, it is desirable to transport them in as large a unit as possible from the viewpoint of transportation costs.

Therefore, the present invention has two features that meet these requirements.
The side panels of each box are connected to form a single connected box, which can be handled as a single box when handling cargo, and is also stable when stacked in large quantities for transportation and storage. This is to obtain a stacked state.

Conventionally, as a means of stabilizing the stacked state, as shown in FIG. 11, a fitting piece a is projected from the end face of the boxes, and the bottom of the upper box is fitted inside the fitting piece a of the lower box. It has been done.

However, this method has the disadvantage that it cannot prevent the box from moving in the direction of the arrow in FIG. 11.

In order to solve this problem, an L-shaped fitting piece is provided at each corner of the box, but this method complicates the assembly work of the box and reduces the strength of the box.
It has many drawbacks.

The present invention solves the above-mentioned drawbacks of the conventional example, and has two
Insert one partition plate into a connecting box made up of several boxes,
In order to strengthen the connection between the two boxes, a fitting protrusion is provided on the upper part of the partition plate, and when the connecting boxes are stacked, the fitting protrusion is provided on the bottom plate of the upper connecting box. It fits into the matching hole to obtain a stable stacked state when stacking a large number of boxes.

Hereinafter, the present invention will be specifically explained with reference to illustrated embodiments.

Figure 1 is a developed view of the connecting box according to the present invention, and the upper and lower views are symmetrical with respect to the center fold line 1, and each has elements forming an independent box. The solid line indicates a tangent line, and the dotted line indicates a broken line.

That is, side plates 3, 3' and 4, 4 are placed around the bottom plates 2, 2',
End plates 5, 5' and 6, 6' are connected, and side plates 3 and 3' are connected via a fold line 1 at the center.

Next, edge plates 7, 8 and 7', 8' and inner end plates 9, 10 and 9'IO' are connected to the end plates 5, 6 and 5', 6', respectively.

In addition, the code|symbol 11 is a protrusion for a lock, and 12 is a hole for a lock.

Further, reference numeral 13 indicates a flap.

Furthermore, fitting holes 14 and 14' are bored in the bottom plates 2 and 2' of the connecting box constructed as described above, and partition plate insertion holes 15 are bored in the side plates 3 and 3'.

Next, when assembling this, first the side plate 3 as shown in Figure 2.
, 3' and 4, 4' and each flap 13
are bent inward, and then the end plates 5, 6 and 5',
6' and inner gable plates 9, 10 and 9'IO
' is bent inward to lock the locking protrusion 11 in the locking hole 12.

In this way, a connecting box as shown in FIG. 3 is completed.

A partition plate as shown in FIG. 4 is inserted into this connection box, and as shown in FIG. The partition pieces 18 are connected, and a fitting recess 19 is bored in the center of the fitting projection 17.

Furthermore, a notch 21 from which a fitting portion 20 protrudes is formed at the outer edge of the partition piece 18.

The partition plate constructed as described above is folded in half along the center fold line 16 and used as shown in FIG.

It goes without saying that this partition plate can be used as a single partition piece 18 by omitting either the upper or lower part of FIG. 5.

In the connecting box according to the present invention, a partition plate as shown in FIG. 4 is inserted into the connecting box shown in FIG.
0 is fitted into the side plates 3, 3' to form the state shown in FIG.

In this state, the two boxes, which were connected only at the upper edges of the side plates 3 and 3', are connected at the bottom of the side plates 3 and 3' by the fitting part 20, and a stable connected state is obtained. It is.

In addition, when these are stacked, as shown in FIG. 7, the fitting protrusion 17 of the lower connection box is connected to the fitting hole 14 of the upper connection box, as shown in FIG.
14' and inserted into the notch 21, and the fitting recess 19 fits into the side plates 3, 3', resulting in extremely stable stacking in which the upper and lower connecting boxes do not move in either direction. It is possible to obtain the state.

8 and 9 show another embodiment of the present invention, in which the fitting holes 14, 14' are extended onto the side plates 3, 3', and the fitting protrusion 17 is fitted in the partition plate. The common recess 19 is omitted.

The stacked state in this embodiment is shown in FIG. 10, where the fitting protrusion 17 of the lower connecting box is connected to the side plate 3 of the upper connecting box.
3' into the fitting holes 14, 14',
The same effects as in the previously described embodiment can be obtained.
