DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sealed container containing a water-repellent substance, and more particularly to a sealed container whose main body is made of a moisture-proof laminated material mainly composed of paper.

[0002]

2. Description of the Related Art Conventionally, as containers for packaging, various kinds of substances which dislike moisture, such as bath detergent, powder detergent, instant coffee, powdered juice, powdered milk, etc. Containers made of materials have been used.

As a container for the water-repellent substance, a resin container or a metal container having an excellent sealing property is desirable.
These have problems such as high cost or difficulty in disposal.

On the other hand, a sealed container using paper has been used as a container for a water-repellent substance for storing such contents.

[0005] Among the sealed containers of this type, the container made of a thick paper plate whose side wall of the container body has a certain strength has the following different structural features in relation to the sealing property. Can be classified into two types.

[0006] First, the side wall of the container body has a rectangular shape. This is because the side wall and the bottom wall are formed linearly so that the sealing between the side wall and the bottom wall is sealed. We can secure it.

Secondly, the side wall of the container body is circular or elliptical. The side wall is formed by spirally winding a band mainly made of paper, while the bottom wall made of a thin metal plate is formed. By connecting to the side wall by caulking, it is possible to ensure the sealing of the connection between the side wall and the bottom wall.

[0008]

However, the former rectangular sealed container is inferior in appearance, usability, mechanical strength and the like as compared with a circular or elliptical container. There is a point.

In the case of the latter circular or elliptical sealed container, since the side wall and the bottom wall are made of different materials, it is difficult to separate and discard the material, and it is difficult to reuse the material. There is a point.

The present invention has been made in view of the above-mentioned conventional problems, and has excellent appearance, usability, and mechanical strength, is easy to separate and discard, and is easy to reuse materials.
It is an object to provide a sealed container for a water-repellent substance.

[0011]

In order to achieve the above object, according to the first aspect of the present invention, a tubular body made of a moisture-proof laminated material mainly composed of paper and having a top opening and a bottom opening is formed.

The leg is folded downward to form a leg, and the leg is bonded to the bottom folded portion on both the inner and outer surfaces.

Accordingly, in the sealed container according to the second aspect of the present invention, the side wall, the lower peripheral edge of the side wall along the bottom opening, and the peripheral edge of the bottom wall are configured as described above.
The effect of the invention of the invention can be more effectively achieved.

Further, according to the third aspect of the present invention, in the sealed container according to the first or second aspect, the side wall is
Of the both ends of the innermost layer, the end facing the inside of the container body is folded back to the side wall and adhered to the other end.

Therefore, in the sealed container according to the third aspect of the present invention, the end of the side wall facing the inside of the container main body, out of the both end portions of the innermost layer, is folded back toward the side wall and the other end is formed. (Adhesive protection structure), it is possible to ensure a predetermined moisture permeability and aroma retention of the sealed container.

On the other hand, according to the invention of claim 4, the above-mentioned claim 1
4. The sealed container according to claim 3, wherein a flange portion is provided on an upper peripheral portion of the side wall along the top opening, and the peripheral portion of the lid sheet has a flange portion along the shape of the flange portion. Glued to.
