Abstract

PROBLEM TO BE SOLVED: To provide a container suitable for recycling which can be made less bulky and easy to handle by enabling the nesting of the container which could not be nested even if it was cut or opened. SOLUTION: In a recyclable container 1, having a cap screwed freely detachably, which can be cut with a pair of scissors or a knife, a container main body is formed so as to have a large diameter on the upper-part side and become gradually narrower toward its lower part. A recyclable container made as paper pack which hermetically stores contents is also formed so as to have a large diameter on the upper-part side and become gradually narrower toward its lower part. A recyclable container made as paper pack for hermetically storing contents whose top is freely unsealed is formed so that when the top is unsealed, the thickness of it becomes gradually greater from the lower end of the container toward an opening in a higher position.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement to make these containers easily recyclable, such as plastic containers or paper pack containers, such as plastic bottles, plastic bottles, milk packs and detergent containers, which are frequently used on a daily basis. .

[0002]

2. Description of the Related Art Plastic containers such as PET bottles and shampoo bottles, and paper pack containers such as milk packs can be cut with scissors or knives. Dedicated scissors also exist, and the environment for easy cutting at home has been set up. However, in general, they are not cut so as to overlap with each other. Many paper pack containers allow the upper surface to be opened by hand, but they do not overlap when opened. Therefore, when disposing of these containers, a method of crushing, cutting and unfolding, or as it is is adopted.

[0003]

These containers were bulky and were very inefficient to dispose of. Also, handling was not easy. Therefore, recycling is difficult to proceed,
It has a number of problems, including dioxin and carbon dioxide emissions, difficulties in securing disposal sites, and illegal dumping.

An object of the present invention is to provide a container suitable for recycling.

[0005]

Means for Solving the Problems The first recycling container of the present invention has a shape in which a number of overlapping shapes are formed in a state where the space is small.
It is included in most parts other than the upper part of the container.

[0006] Like the first recycling container, the second recycling container according to the present invention has a shape in which many spaces are overlapped in a small space state except for the upper part of the container.

[0007] The third recycling container of the present invention is formed such that when the upper surface is opened, the entire container is overlapped with many spaces in a state where the space is small.

[0008]

First Embodiment A first embodiment of the present invention will be described in detail with reference to FIG. FIG. 2 is a side view of a plastic bottle 1 in which the present invention is implemented. A diameter portion 4 having a maximum thickness is provided above the height direction, and the diameter is gradually reduced from the diameter portion 4 having a maximum thickness toward the lower end of the container.

The container is not limited to a plastic bottle, but may be a container made of another material that can be easily cut with scissors or a knife.

[0010]

Second Embodiment A second embodiment of the present invention will be described in detail with reference to FIG. This figure is of a paper pack container 5 for sealingly storing contents. Above the height direction, there is a diameter portion 6 having the maximum thickness, and the diameter portion 6 having the maximum thickness is formed so as to gradually become thinner toward the lower end of the container.

[0011]

Third Embodiment A third embodiment of the present invention will be described in detail with reference to FIG. These figures show a paper pack container 9 that can be easily opened like a milk pack.
belongs to. As shown in (b) and (c), when the upper surface is opened, the lower end portion 10 is made gradually thicker toward the opening.

[0012]

Use Example 1 A first use example of the first embodiment of the present invention will be described with reference to FIG. The diameter portion 4 having the largest thickness is cut with scissors or a knife (a dedicated scissor is desirable). The lower side 3 formed by the cutting is overlaid as shown in FIG. The upper side 2 may be placed in the lower side 3 or may be collected separately.

[0013]

[Use Example 2] A use example of the second recycling container according to the second embodiment of the present invention will be described with reference to FIG. The diameter portion 6 having the largest thickness is cut with scissors or a knife (a dedicated scissor is desirable). The lower side 7 formed by the cutting is overlaid as shown in FIG. The upper side 8 may be placed inside the lower side 7 or may be collected separately.

[0014]

[Use Example 3] In order to use the third recycling container according to the third embodiment of the present invention, the upper surface of the container is opened by hand as shown in FIGS. I'll do it again.

[0015]

According to the present invention, the bulk of the container can be reduced.
Since it can be handled easily, recycling becomes easier.

The structure in which the thickness is gradually changed allows the layers to be overlapped with little clearance.

If standardized to some extent, separate collection becomes easy.

The recycling container according to the first aspect can be applied to a container whose upper surface cannot be easily opened, such as a milk pack. Anyway, scissors suitable for cutting three-dimensional containers are already on the market.

In the recycling container according to the first aspect, the cap portion can be further provided, so that the containers can be efficiently stacked.

In the recycling container according to the first aspect, since the cap portion can be made of a material different from the material of the container body, the efficiency of recycling increases.

The recycling container according to the second aspect can be applied to a paper pack whose upper surface cannot be opened by hand. or,
Even if the top surface can be opened, it is good when there is a spout above and it is not convenient to stack.

In the recycling container according to the third aspect of the present invention, many of the existing paper pack containers can be easily opened because the upper surface thereof can be easily opened.
