2. Description of the Related Art In recent years, technological advances have been made in synthetic resin films such as polyethylene and the like, and the chemical resistance thereof has been improved, and containers for storing various chemicals, foods, etc. have been manufactured using the films. For example, a small bag-shaped container made of a synthetic resin film (for example, polyethylene) capable of accommodating 5 to 20 liters has been developed. As one of them, there is known one in which one bag-shaped container is accommodated in a cardboard box and the cap is opened and closed so that the contained liquid or the like can be used at any time.

In a closed container made of a synthetic resin film of such a system, the synthetic resin film inside is soft, and since the contained one is a liquid material, it does not have the shape-retaining property. Even if the volume of the container becomes smaller due to the stored liquid, it has the advantage of being extremely convenient and convenient because the outer corrugated cardboard box is used as it is, and it has become particularly popular recently in various fields. ing.

As a closed container made of a synthetic resin film of this type, for example, one having a rectangular bag-like structure shown in FIG. 9 has been used. The hermetically sealed container 10 is configured such that a required portion of the synthetic resin film is heat-sealed 20 so that the stored liquid does not leak, and a corner at one end thereof is
There was an opening 40 with a cap 30. A short pipe 50 is sealed and embedded at a position opposite to the opening 40 so as to facilitate gripping.

That is, the closed container 10 may contain a liquid with high viscosity (food such as fresh cream) in addition to a normal liquid, and the internal pressure decreases as it is used, and the cardboard box is simply tilted. Will not flow easily. At this time, it is necessary to take out the closed container 10 from the cardboard box, hold it with both hands, and handle the flexible container made of film to squeeze out the residual liquid inside. At that time, this closed container 1
It is natural to hold the upper end of 0 with one hand and handle it with the other hand from top to bottom, and the above-mentioned pipe 50 is buried in order to make it easy to hold the upper end of the closed container 10.

[0006]

However, in the closed container 10 having the above-described structure, the pipe 5 is positioned inside the two films and then sealed (heat-sealed),
The manufacturing process becomes complicated and another member called a pipe is required. Further, when the pipe 5 of the closed container 10 is to be gripped, it can only be gripped, a stable gripping state cannot be obtained, and it is difficult to apply force to the squeezing action.

In view of the problems of the prior art, the present invention provides a stable gripping state with a simple structure without using a separate member and without requiring a special manufacturing process. It is an object of the present invention to provide a closed container made of a synthetic resin film which is easy to squeeze out.

[0008]

In order to achieve the above object, a closed container made of a synthetic resin film according to the present invention constitutes a container body by sealing a synthetic resin film. In a closed container made of a synthetic resin film having an opening with a cap in the vicinity of a side edge, a gripping portion that seals the vicinity of the side edge opposite to the opening and separates it from the storage portion of the container body is provided, Moreover, a means of providing an opening for gripping in the gripping portion was taken.

Alternatively, in a hermetically sealed container made of a synthetic resin film, the synthetic resin film is sealed to form a container body, and an opening with a cap is provided near one side edge of the container body. A means for sealing the vicinity of the edge on the side opposite to the opening and providing a gripping part for separating from the accommodating part of the container body, and providing a perforation for forming an opening for gripping the gripping part is taken. It was.

The container body is formed in a substantially rectangular shape in a plan view, the opening is located at one corner of the container body, and the gripper having the opening is diagonal to the opening. Preferably, it is configured to be formed in a corner located at. Further, the container body is formed in a substantially rectangular shape in a plan view, the opening is provided at a substantially middle position of a shorter side of the container body, and a grip portion having the opening faces the opening. It may be configured so as to be formed at both corners of the side to be formed. Further, the container body is formed in a substantially rectangular shape in a plan view, the opening is provided at a substantially intermediate position of the shorter side of the container body, and the grip having the opening faces the opening. It may be formed at a substantially middle position of the side to be formed.

The synthetic resin film referred to in the present invention means, for example, a film of polyolefin such as polyethylene and polypropylene, vinyl chloride and the like, and includes its thickness and sheet thickness. The term "seal" generally refers to heat-sealing having water-tightness, but includes the case where an adhesive is used. The shape of the container is not limited to a rectangular shape, a triangular shape, or the like.

[0012]

According to the present invention, since the storage portion of the container body is isolated by only the seal of the synthetic resin film forming the closed container to form the grip portion, and the grip portion is formed with an opening that can be held by hand. The grip portion can be formed at the same time in the sealing process of the container body without requiring a manufacturing process of preparing a pipe or burying the pipe at a predetermined position between the films.

When the closed container taken out from the cardboard box is squeezed in the final stage of the contained liquid, a hand is put into the opening of the gripping portion to securely and stably grip it.
It is possible to apply a squeezing (handling) action with the other hand, and to pour the remaining contained liquid into a predetermined external container (or device) through the opening with the cap removed.

When the opening of the grip portion is not initially opened and the perforation is formed therein, the hand is pushed prior to the grip and the opening is broken along the perforation. It's good. After that, the same throttling action as described above is performed.
