Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a structured box suitable as a take-out box and a shipping box for fresh food and other foods.

(Problems to be Solved by Conventional Techniques and Inventions) Conventionally, a plurality of plates made of synthetic resin foam are elastically fitted with notches and protrusions provided at both end portions thereof to form one frame. There is one in which four peripheral walls are formed by connecting them in a circular shape, and a separate bottom plate is fitted and fixed to the inner surfaces of these four peripheral walls to form an integral box (for example, Japanese Utility Model Laid-Open No. 62-118023). This is a box body that has heat retention and water resistance peculiar to synthetic resin foam, and is also excellent in strength.Before assembly, each part is a flat plate body, so it has the advantage of space saving. However, there was the inconvenience that a special device was required for the assembly process.

(Means for Solving the Problem) On the other hand, according to the present invention, an assembly box made of the synthetic resin foam is formed by a base plate in which four peripheral walls are previously arranged around a bottom plate like a normal paper box base paper. As it forms
After assembling, it is tightly fitted into the inside of a paper box having an upper surface opened by assembling one sheet of base paper separately to form an integral box body, which has the advantages of the synthetic resin foam box. ,
(EN) A box body which is easy to assemble and which has an excellent appearance by printing the paper box which is an outer box in advance.

(Embodiment of the Invention) An embodiment of the invention will be described with reference to the drawings. As shown in FIG. 1, the invention comprises an inner box A formed by bending one synthetic resin foam plate into one sheet. It is formed by tightly fitting in a paper box B assembled from the assembled base paper.

FIG. 2 shows an inner box original plate 1 for assembling the inner box A.
Shows a single rectangular synthetic resin foam plate, along with the perforations 2 are cut along the periphery, four corners are cut off, and four peripheral wall plates 4.4.4.4 are continuously provided around the bottom plate 3. The notches 5 and the protrusions 6 are alternately provided at the joint ends of these wall plates.

FIG. 3 shows an inner box A produced by using the inner box original plate 1. That is, the inner box original plate 1 is formed by bending the four circumferential wall plates 4.4.4.4 upward with the stamped ridges 2 ... As the lower surface, and combining the protrusions 6 ... With the notches 5 ... It is a thing.

Next, FIG. 4 shows an assembly base paper 7 for the paper box B. This product is made by cutting out a piece of thick paper, providing folding lines to form side plates 9 and folded back inner plates 10 around the bottom plate 8, respectively, and providing folding plates 11 in the portions surrounded by the respective side plates. A pair of side plates are folded back.
It is formed by attaching 2 ...

FIG. 5 shows a state in which the paper box B is assembled with the assembly base paper 7. That is, the four side plates 9 ... Are erected around the bottom plate 8 with the folding plates 11.11 sandwiched therebetween, and the corresponding one set of the folded back inner plates 10 is folded inward, and the reinforcing pieces 12.12 thereof are replaced with the other ones. After being attached to the pair of side plates 9, the folded back inner plates 10.10 of the other pair of side plates are respectively folded inward to form an integral paper box B as shown in FIG. Then, the inner box A is pushed into the paper box B to form the box shown in FIG.

(Effect of the Invention) As described above, this invention is formed by closely fitting the inner box A assembled with the base plate 1 made of the synthetic resin foam plate into the paper box B assembled with 7 with one base paper. Therefore, in the inner box A, it is sufficient that the joint portions of the four peripheral wall plates 4 ... Are simply assembled by hand, and the inner box A and the paper box B are fitted together without using an adhesive. In any case, the inner box A of the paper box B serves as a core and is not easily deformed. Before assembling, both the inner box A and the paper box B are made of the original plate 1 and the original paper 7, so that they do not take up a lot of space for storage. Furthermore, the paper box B must be pre-printed to form a beautiful appearance. You can
