DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an amorphous container with a plug for filling a liquid beverage such as juice inside.

[0002]

2. Description of the Related Art An irregular shaped container with a spout is used by filling a liquid beverage such as a juice therein, and is disclosed in, for example, Japanese Utility Model Publication No. 2-21399 and Japanese Patent Application Laid-Open No. 8-3815.
No. 1 discloses this.

The liquid-filled container disclosed in Japanese Utility Model Publication No. 22399/1990 forms a bag-shaped container body having an upper opening made of a flexible film, and a take-out device having a mouth portion and a conduit portion. The removal device is fixed to the opening of the bag-shaped container body so that the portion extends into the internal space of the bag-shaped container body.

In the package for home brewing disclosed in Japanese Patent Application Laid-Open No. H8-38151, two webs form side walls facing each other, and one web forms a bottom wall. An opening nozzle is provided, and a stopper is fitted to the opening nozzle.

[0005]

[Problems to be solved by the invention]
In the conventional liquid-filled container disclosed in Japanese Patent No. 21399, a bag-shaped container main body is formed by attaching four flexible films to form a bag, and the outer peripheral portion is cut into a predetermined shape. Therefore, the four corners of the outer periphery of the liquid-filled container are cut surfaces of the flexible film, and there is a possibility that the hand or finger may be damaged during handling. In addition, in order to form a bag by laminating four flexible films,
The length of the seal portion becomes longer and the cost of the heat welding operation increases, and the yield of the material is low because the outer peripheral portion of the bag-shaped film is cut. Furthermore, since the liquid-filled container made of a bag-shaped film is not self-supporting, when it is filled with drinking water and sold at a store, it must be sold sideways, which requires a large space. Will be.

Further, in the package for home brewing disclosed in Japanese Patent Application Laid-Open No. 8-38151, a bottom wall is formed by a single web below a side wall formed by two webs. Although the package can stand on its own, both sides are cut surfaces of the web, which may damage hands and fingers during handling, and the length of the seal portion becomes longer because three webs are formed in a bag shape. As a result, the cost of the heat welding operation is increased, and the yield of the material is low. Further, since the side wall is formed by the two webs, the package cannot have a thickness, and there is a problem that the content of the liquid beverage to be filled therein is reduced.

An object of the present invention is to solve such a problem, and it is an object of the present invention to provide an unsealed container with a plug which is easy to handle and sell while reducing manufacturing costs.
