Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 This invention relates to a folding box that can be stacked in multiple stages.

[0002]

[Prior art]

 The conventional folding box for multi-stage stacking was a square or rectangular folding box with an upper edge of the same level, so that when stacked in multiple stages, there was a drawback that horizontal misalignment was caused and the stuffing spilled out.

There is also known a structure in which a crosspiece is fixed to the bottom of a folding box, and the crosspiece is fitted to a lower folding box to prevent lateral displacement of the folding box. Had the drawback of being complex and expensive to manufacture.

[0004] Furthermore, in the conventional folding box, a V-shaped cut is formed in a plate material forming a bottom, a side wall, and the like, and the sheet is bent so that the cut is on the inside. There was a drawback that the fillings, for example, rice grains and confectionery waste, entered and were not hygienic.

[0005]

[Problems to be solved by the invention]

 This invention has been devised in order to eliminate the drawbacks described in the prior art, and has as its object to provide a folding box which can surely prevent lateral displacement and is hygienic and can be stacked in multiple layers.

[0006]

[Means for Solving the Problems]

 The folding box of the present invention, which can be stacked in multiple stages, has a U-shaped transverse groove formed in a plate material forming the front and rear walls, spaced apart from a lower end of the plate material by a predetermined length upward, and a predetermined interval is formed at both ends of the plate material. Then, a U-shaped vertical groove is bored, and a bottom having the same width as a predetermined interval between the vertical grooves of the plate forming the front and rear walls and the front and rear walls are formed in the plate forming the bottom and side walls. A cut is made between the bottom and the side wall so as to form a side wall having the same height as the height of the plate. Another folded box to be overlapped is a folded U-shaped plate formed with U-shaped horizontal grooves and vertical grooves of the plate forming the front and rear walls, and cutouts of the plate forming the bottom and the side walls on the outside. The folding box which is configured by fitting the front and rear ends and which is stacked on the uppermost stage is the folding box of the other folding box. The upper edge of the side wall portion of the plate material forming the bottom and side walls fitted to the plate material forming the rear wall and the upper edge of the plate material forming the front and rear walls are at the same level. It is a thing.

[0007]

[Embodiment of the invention]

 One example of an embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. A U-shaped lateral groove 2 is formed at a predetermined distance L upward from the lower end of the plate 1, and U-shaped vertical grooves 3, 3 are provided at both ends of the plate members 1, 1 at a predetermined distance D. Has been drilled.

As shown in FIGS. 4 and 5, a predetermined distance D between the vertical grooves 3 of the plate materials 1 and 1 forming the front and rear walls is formed on a plate material 4 made of wood, cardboard or the like forming the bottom and side walls. And a cut 7 separating the bottom portion 5 and the side wall portion 6 so that the bottom portion 5 has the same width W and the side wall portion 6 has the same height H as the height h of the plate materials 1, 1 forming the front and rear walls. , 7 are drilled.

The width t of the lateral grooves 2 and the vertical grooves 3 is designed to be slightly smaller than the thickness T of the plate 4, and the cuts 7 of the plate 4 are 70 to 90 of the thickness T. It is drilled to a depth of about%.

[0010] Except for the folding box A superimposed on the uppermost row, other folding boxes B, B,... Laminated below the uppermost folding box A form the front and rear walls as shown in FIGS. The plate material 4 ′ formed in a U-shape by folding the U-shaped horizontal groove 2 and the vertical groove 3, 3 of the U-shaped plate material 1, 1 with the cuts 7, 7 of the plate material 4 forming the bottom and side walls outside. The front and rear ends a and b are fitted.

Therefore, as shown in FIG. 7, in the folding box B, the upper edge d of the side wall portion 6 is approximately the predetermined length L longer than the upper edge c of the plate material 1, 1 forming the front and rear walls. Protrude by the length obtained by adding the width t. The projecting portion has the following operation and effect.

The protruding portion of the lower folding box B is formed by the vertical groove 3 of the upper folding box B as shown in FIG. 9 and the folded portion of the bottom portion 5 and the side wall portion 6 as shown in FIG. To prevent the lateral displacement between the upper and lower folding boxes B, B, and substantially seal the lower folding box B, thereby preventing intrusion of dust and the like from the outside.

As shown in FIG. 8, the folding box A stacked on the uppermost stage is a plate member forming bottom and side walls fitted to the plate members 1, 1 forming the front and rear walls of the other folding boxes B, B,. The upper edge c of the side wall 6 of the plate 4 and the upper edge d of the plate material 1 forming the front and rear walls are at the same level. Therefore, as shown in FIG. 9, the folding box A can be covered with the lid 9 without any gap.

[0014]

[Effect of the invention]

 Since the present invention is configured as described above, it has the following effects. Lateral displacement of stacked folded boxes can be reliably prevented. Since the stacked folding boxes are substantially sealed, dust and the like do not enter from outside. Since the cut is turned back to the outside, rice grain and confectionery do not enter into the cut, which is sanitary. Since there is no cut inside, it does not leak even if you put juice. Since the structure is simple, mass production can be performed at low cost.
