Abstract

PROBLEM TO BE SOLVED: To reduce capacity after use by holding a hole of one end of a container between a projecting structure and a recessed structure. SOLUTION: The lid 8 of a container 1 is constructed so that a recessed structure 2 and a projecting structure 4 are opened/closed by a hinge 6. In the end of the container 1 a hole 7 is made. After use of its contents, the container 1 is folded, the projecting structure 4 is separated from the recessed structure 2, and the hole 7 of the container 1 is made to coincide with the recess 3 of the recessed structure 2. Then, the projection 5 of the projecting structure 4 is firmly fixed by being passed through the hole 7 of the container 1 and fitted in the recess 3 of the recessed structure 2. This makes it possible to compress the container 1 after the use of the contents. Also, because the hole 7 is held between the projecting structure 4 and recessed structure 2, the container 1 is prevented from returning to its original state by inflow of air.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a novel plastic container. More specifically, it relates to a new plastic container whose volume can be reduced after use.

[0002]

2. Description of the Related Art A conventional plastic container has the same volume as before use because air flows into the container even after use. For this reason, when disposing of used plastic containers, there is a problem in terms of work efficiency or storage location.

[0003]

SUMMARY OF THE INVENTION The present invention has been made to solve these problems, and an object of the invention is to provide a plastic container whose volume can be reduced after use. It is an object of the present invention to provide a plastic container that can reduce the volume by holding a hole at one end of the container by the convex structure and the concave structure.

[0004]

Means for Solving the Problems The present invention relates to a plastic container having a hole, a concave structure and a convex structure for sandwiching the hole.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION It is preferable that the concave structure and the convex structure of the plastic container of the present invention be sandwiched by fitting.

[0006] It is preferable that the concave structure and the convex structure are joined because they are not lost and they can be easily mounted.

As the joint between the concave structure and the convex structure, any structure can be used as long as it can be joined. However, a hinge is particularly preferable in terms of ease of attachment and detachment.

The hole may be any hole that can be sandwiched between the concave structure and the convex structure by reducing the size of the container. However, it is preferable to provide the hole at the end of the container, and at the end remote from the concave structure and the convex structure. It is particularly preferable to provide them.

The number of holes may be one to three, but usually one is particularly preferable from the viewpoint of work and appearance. Further, when the container is wide and can be folded in many directions, the volume can be easily reduced by providing a plurality of holes as compared with the case of a single hole.

The size of the hole may be any size as long as it can be sandwiched between the convex structure and the concave structure, and may be larger than the convex structure and not large enough to be removed from the lid having the convex structure.

The shape of the hole may be a slit as long as it can be sandwiched between the convex structure and the concave structure, but a circular or elliptical shape is particularly preferable from the viewpoint of work.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be specifically described below with reference to the drawings. FIG. 1 is a perspective view of one container of the present invention, and FIG. 2 shows a state before the container is compressed to reduce the size after use and the hole is sandwiched between the convex structure and the concave structure. FIG. 3 is a side view of a container compressed by pinching a hole, FIG. 4 is a partial view of a portion that pinches a hole, and FIG. 5 is a view for forming a portion of a hole. This is a mold seal mold. FIG. 1 shows an example of the container 1 of the present invention, in which a lid is used as a convex structure.
The lid 8 of the container 1 is configured such that the concave structure 2 and the convex structure 4 can be opened and closed by a hinge 6. The end of the container 1 is provided with a hole 7. The container 1 in which the contents have been used is folded as shown in FIG. . Then, the convex structure 4
Is fitted and fixed to the concave portion 3 of the concave structure 2 through the hole 7 of the container. In this way, the container
It can be compressed to a volume of about ４, and is disposed of in a state where the volume is reduced. In this container, since the hole is sandwiched between the convex structure and the concave structure, air does not flow in and does not return to the original state.

FIG. 4 shows a structure in which a convex structure and a concave structure joined by a hinge 6 are provided on a lid to separately hold a hole of a container. After the container has been used up, the container is folded, the hole 7 of the container is aligned with the concave portion 3 of the concave structure 2, the convex portion 5 of the convex structure 4 is inserted into the concave portion 3 of the concave structure 2, and the container is discarded with the volume reduced To process. In this container, the holes are fixed by the convex structure and the concave structure, so that air does not flow in and return to the original state.

[0014]

According to the present invention, the plastic container
Since the volume can be reduced after use, waste can be efficiently treated and the storage space can be reduced. Further, the plastic container of the present invention is
Since only a small hole is required for fixing, the portion where the hole is opened can be reduced, and there is no uncomfortable feeling during use and the design is excellent. Also, the plastic container can be hung up and used during use using the holes. Furthermore, since it is sandwiched and fixed by the lid, the plastic container does not return to its original shape and can be kept in a completely compressed shape.
