BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container whose opening is hermetically sealed with a sealing material. The container of the present invention can be hermetically sealed, and is suitable as, for example, a powder detergent container.

[0002]

2. Description of the Related Art As a conventional technique relating to a container whose opening is sealed with a sealing material, those described in JP-A-56-151672 and JP-A-55-44729 are known. That is, Japanese Patent Laid-Open No. 56-151672 discloses a paper cup having a curl portion on the upper portion of the body wall.
A container in which a lid body coated with an adhesive is covered at a required position on the back surface of the top plate is described.

Further, in Japanese Utility Model Laid-Open No. 55-44729, an adhesive is applied to a cup-shaped container body made of paper or the like having a flange formed at the opening, and a lid made of a single aluminum foil or the like is melt-bonded. The container is listed. Further, as a conventional technique regarding a container having a reinforced opening, a practical example is Shokai Sho 5
The thing etc. which are described in 5-98708 publication are known,
The publication describes a container in which a bent portion connected to a side wall is bent inward and adhered to form an opening.

[0004]

However, the above-mentioned prior art has the following problems. That is,
In the container described in Japanese Unexamined Patent Publication No. 56-151672, the edge curl portion is formed, and the lid curd portion is covered and pressed for adhesion.
The lid is adhered in a strip shape instead of a linear shape because the curl portion of the lip is slightly deformed, and the opening can be reliably sealed with the lid, but the curl portion of the polygonal column is not covered with the lip curl portion. When it is formed, it has a tear at the corner and cannot be sealed.

Further, in the container described in Japanese Utility Model Laid-Open No. 55-44729, a flange is formed in the opening, and the width of the flange is set to a size sufficient for applying an adhesive, thereby forming the opening. The lid can be securely sealed with a lid, but when the lid is pressed against the flange, the flange escapes in the direction opposite to the lid. Therefore, a flange pressing device or the like is required for reliable sealing. Further, when the thickness of the side wall is increased and the flange is omitted, the strength of the cup-shaped container body becomes unnecessarily large, resulting in a large loss of material.

In the containers described in these publications, the edge curl portion or the flange protrudes to the side of the opening. Therefore, when storing a plurality of containers in a corrugated cardboard box or the like, to prevent disturbance. Since it was necessary to provide a partition wall and the like to house each container in each compartment, a container that does not require these protruding portions is desired. Also, the actual exploitation 55
In the container described in JP-A-98708, the opening can be reinforced, but there is no description or suggestion of sealing the opening with a sealing material. Even if an attempt is made to seal the opening with a sealing material, the bent portion is bent inward, and the tip of the peripheral edge of the opening is formed in a semicircular shape with the thickness of the side wall as a radius. Even if they can be adhered linearly, they cannot be adhered in a band, and the opening cannot be reliably sealed. In addition, it is bent inward on the side wall.
Across the bent part (folded piece) and the side wall (cylindrical body part)
There is no mention or suggestion of providing a fixture.
Yes.

Accordingly, it is an object of the present invention is to easily can reliably seal the opening with sealing material, moreover polygonal columns of the and fixture without major projections in the opening side may be mounted stably An object is to provide a container, for example, a container suitable as a container for powder detergent and the like.
