Description

[Detailed description of the invention] The present invention relates to a container that can be automatically folded without pasting a part of the corners and can form a strong box.
In particular, in a picture frame type box consisting of a bottom plate, inner and outer plates, upper edge plate, inner and outer end plates, adhesive plates, connecting pieces, etc., projecting pieces are provided in the shape of a key on the outer sides of the left and right ends of the upper edge of the side wall side, and the end plate is Folded pieces are connected to the upper and lower ends of the upper edge of the wall via a folded line, and this folded piece is integrally connected to a folded piece having a diagonal folded line via the folded line. In folding and assembling the box, the folded piece is folded back to the upper edge on the end wall side and overlapped, and the upper edge and the folded piece are respectively folded onto the protruding piece to form a part of the corner. This relates to picture frame boxes.

Regarding conventional boxes of this kind, for example, Japanese Utility Model Publication No. 52-41003 and Utility Model Publication No. 53-1, both of which were invented by the present inventor.
The techniques shown in Japanese Patent No. 5611 and Japanese Utility Model Publication No. 55-20577 are known, but the former two methods are manual assembly methods, which have poor workability, and have extremely complex structures that require skill to assemble. Although the latter can be manufactured automatically by a machine, it is necessary to apply glue to one of the connecting pieces that pass through the diagonal folding line of a part of the corner of the box. Since it has to be applied to the triangular pieces, it is difficult to apply the glue at the right time and to prevent the glue from adhering to other parts, resulting in extremely poor workability and the risk of polymerization of the side walls. is a 4-piece polymerization of the bottom plate, adhesive piece, and inner and outer plates, whereas this part is a 2-layer polymerization of a bent piece and an outer gable plate, so sufficient press pressure after pasting is applied to this part. There were drawbacks such as easy peeling.

The box according to the present invention relates to a completely new technology developed in view of the drawbacks of the prior art.

To specifically explain one embodiment of the box according to the present invention with reference to the drawings, in FIG. An outer plate 2, a territorial edge plate 3, an inner plate 4 whose vertical width is narrower than the outer plate 2 by the thickness of the paper, and an adhesive piece 5 are provided in series through the outer plate 2, respectively, and an outer plate 5 is provided on the left and right sides of the bottom plate 1 via a vertically folded curve. An inner gable board 8 and an overlapping piece 9 each having a vertical width narrower than the paper thickness than the gable board 6, the upper gable board 7, and the outer gable board 6 are provided in series, and the outer gable board 2 and the outer gable board 6 are connected at both ends through folding lines. In addition, the left and right widths of the inner side plates 4 are narrower than the left and right widths of the territorial edge plates 3, and the left and right ends of the upper side edge plates 3 are A protruding piece 11 is provided in the shape of a key to protrude toward the plate 4, and the upper edge plate 7
The upper and lower outer edges of the upper and lower edges are gradually cut off obliquely, and at the tips thereof, folded pieces 12 having a width that is approximately equal to or smaller than the left and right ends of the upper edge plate 7 are protruded through the folded edges, Further, the folded piece 12 is connected to the folded piece 10 via a folding line C, and a notch d is bored inside the upper and lower ends of the inner gable plate 8 and communicates with the cutout part of the upper edge plate 7. Notches e are formed on the outer sides of the upper and lower ends of the overlapping piece 9, and intermediate protrusions f surrounded by these notches d and e are provided so as to be able to fit into the left and right ends of the inner plate 4, so that the entire structure is is configured.

In assembling the box according to the present invention, as shown in FIG. are folded over the inner surfaces of the outer plate 2 and the bottom plate 1, respectively, and the adhesive strip 5 is pasted at a predetermined position on the bottom plate 1. Next, as shown in FIG. While gradually standing up, the inner plate 4 is laid down onto the adhesive piece 5, and the cut upper edge plate 3 and the outer plate 2 are superimposed on the inner plate 4, and the protrusion provided on the cut upper edge plate 3 is A piece 11 is provided to protrude inward from a part of the corner of the bottom plate 1, and at the same time, the folded piece 10 and the folded piece 12 connected thereto are folded over the inner surfaces of the outer gable plate 6 and the sojo edge plate 7, respectively, so that the whole is formed into a sojo edge. Fold it over the inner surface of the board 7, and then superimpose the top board 7, the inner board 8, and the overlapping piece 9 on the top board 6 and the bottom board 1 via the folding line between the top board 6 and the top board 7, and flatten it. In this state, it can be stored, transported, and delivered to a customer.

In order to finally assemble the box of the present invention, as shown in FIGS. 4 to 7, first the inner and outer panels 2 and 4 are erected to form the side walls, and then the outer end panels 6 and the top edge panels are assembled. 7 is raised around the bottom plate 1, the folded piece 12 is folded over the inner surface of the upper edge plate 7, and the connecting piece 1 is folded by the action of this folded piece 12.
0 is folded in half along the diagonal folding line a and is automatically folded onto the inner surface of the outer plate 6. Then, when the upper edge plate 7 is folded horizontally, the folded piece 12 overlapped with the inner surface is placed on the protruding piece 11. When the inner gable plate 8 is folded vertically inward and the overlapped piece 9 is superimposed on the inner surface of the bottom plate 1, the intermediate protrusions f protruding from both ends of these pieces are fitted into the ends of the inner plate 4, This allows a part of the corner of the box to be engaged.

As mentioned above, in the box according to the present invention, the inner plate 4 is made narrower than the outer plate 2 by the paper thickness, so the adhesive strip 5 is automatically moved inward when forming the side wall surface of the box. It can be completely attached to the bottom plate 1 and can prevent the side wall surface from tilting outward when assembled and stood up.In addition, in the present box, narrow folding pieces 12 are provided at both ends of the top edge plate 7. Since the folding piece 12 is connected to the folding piece 10 via the folding line C, the folding piece 12 is connected to the folding edge when assembling a part of the corner of the box. It is folded back onto the inner surface of the plate 7 and serves as a guide to attract the folding piece 10 and automatically bending the diagonal folding line a inward, so that the folding piece 1 is folded like a conventional box.
There is no need to attach a part of the outer gable plate 6 to the inner surface of the outer gable plate 6, and the bent piece 10 can be formed by standing the outer gable plate 6 and the upper edge plate 7.
can be automatically folded inward, and in order to adhere a part of the folded piece 10 to the inner surface of the outer gable board 6 as in the past, special gluing timing is required during mechanical pasting, or There is no risk of glue adhering to the surrounding areas, and there is no risk of peeling or scraping of the glued parts, allowing the box manufacturing work to be carried out quickly, easily and reliably. Since the projecting pieces 11 are overlapped with some of the protruding pieces 11 that protrude inward, it is possible to increase the strength of a part of the corner of the box.
Since one side of the box 0 is held down, there is no fear that part of the corner of the box will open due to external pressure and the bent piece 10 will be exposed. Since the protruding part f is provided by e, this protruding part f is fitted into the end of the inner plate 4, thereby locking a part of the corner of the box, preventing the side wall surface from falling inward, and keeping it upright. It has the characteristic that it can be constructed into a neat box with a simple design.
