BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a closed container with a protective handle made of a synthetic resin film, for example, a liquid material,
Fine powder or semi-liquid chemicals, foods, seasonings,
The present invention relates to a closed container with a protective handle, which is made of a synthetic resin film capable of containing alcoholic beverages and the like.

[0002]

2. Description of the Related Art Recently, technological improvements in synthetic resin films such as polyethylene have been advanced and chemical resistance has been improved, and containers for storing various chemicals, foods, etc. have been manufactured using the films. . As a small-sized synthetic resin film (for example, polyethylene) bag-shaped container, 5 to 20
A liter capacity has been developed. As one of them, there has been proposed one in which a bag-shaped container is housed in a cardboard box and a cap is opened / closed in this state so that the contained liquid or the like can be used at any time.

This type of closed container is made of a synthetic resin film and is soft, and since it contains a liquid material, it does not retain its shape. Therefore, the use of the liquid material reduces the volume of the container. Even so, the advantage is that the outer corrugated cardboard box can be used as it is and is very convenient, and it has begun to spread in the technical field using various liquid materials. However, this type of closed container is difficult to hold by hand when taking out the contents from the cardboard box, and for this reason, there is a method of equipping one side edge of the container body with a gripping pipe or other members. Although it has been adopted, there are problems that it is difficult to manufacture and the gripped state is difficult to stabilize.

Therefore, the present inventor has proposed, as a closed container of this type, Japanese Patent Application No.
-240590 proposed a new closed container.
As shown in FIG. 8, this closed container constitutes a container body 1 by sealing a synthetic resin film 1a,
An opening 3 with a cap 3 near one side edge of this container body
In a closed container made of a synthetic resin film provided with, there is provided a gripping part 5 for separating the storage part 1b of the container body 1 by sealing 4 near the edge opposite to the opening part 3, and
The grip portion 5 is provided with an opening 5a for gripping.

As a result, as shown in FIG. 8, it is possible to obtain a hermetically sealed container which is easy to hold and can be easily squeezed by a simple structure using the material of the container. .

[0006]

The closed container made of the synthetic resin film described above was epoch-making in that it had a handle structure using the material of the container. However, as shown in Figure 9,
In the usage state as shown in Fig. 5, when a large amount of the contained items still remains when the fingers are inserted into the opening 5a of the grasping portion 5 and grasped, the film is bent into a thin string state due to the weight of the contained items, and There was a problem that it hurts. In particular,
In the case of a semi-fluid containment, it takes time to squeeze out and receives the reaction force of the squeezing operation of the other hand,
There is a problem in that the fingers of the hand placed in the opening 5a become even more painful. In addition, such a situation occurs not only when the container is squeezed out but also when the container is carried, and there is also a problem that the container cannot be easily transported.

The present invention solves the above-mentioned problems in the closed container made of the synthetic resin film proposed by the present inventor, and obtains a comfortable gripping state that does not cause pain in fingers during a long suspending operation. An object of the present invention is to provide a closed container with a protective handle made of a synthetic resin film.

[0008]

In order to achieve the above object, the present invention constitutes a container body 1 by sealing a synthetic resin film 1a, and a cap 3 is provided near one side edge of the container body 1. Of the container body 1b of the container main body 1

An upper edge 6 of at least one side surface of the handle opening 6
It was prepared for a.

In the present invention, it is preferable that the finger protection member 7 is formed of a plate-like member and is bonded to at least one side surface of the handle opening 6. Further, it is more preferable that the finger protecting member 7 is formed of a synthetic resin plate-like member in an annular shape and is bonded to the entire inner circumference of at least one side surface of the handle opening 6 by heat welding. Alternatively, the finger protection member 7 may be formed of a pipe having a slit 7a extending in the longitudinal direction thereof, and may be provided on at least the upper edge 6a of the handle opening 6. Further, the finger protection member 7 is composed of a pipe having a slit 7a extending in the longitudinal direction thereof, and a plate-shaped body or an annular plate-shaped body adhered to at least one side surface of the handle opening 6. The pipe may be fitted in an annular plate-shaped body.

Incidentally, the plate-like body of the finger protection member 7 referred to in the present invention includes a sheet-like body which is relatively thin if it has hardness,
Any of various known materials may be used as the material, and when the handle opening 6 is adhered by heat welding (one side or both sides).
In addition, a material that is compatible with the synthetic resin film of the container body 1 should be selected. Further, the pipe as the finger protection member 7 may be made of synthetic resin or cardboard as long as it is a material having shape retention capable of providing a soft gripping surface against the fingers, and Regarding the shape, the cross section such as a pipe may be circular, or may be elliptical or oval.

When using this pipe, the upper edge 6 of the grip opening 6, which has the greatest influence on the grip of the finger, is larger than that of the grip opening 6.
Not only a linear shape that is fitted into only a, but also an arc shape (upper chord shape) that fits into the inner peripheral portion of the grip opening 6 may be formed. Further, the gripping portions 5 near the edge opposite to the opening 2 do not have to be arranged on diagonal lines facing each other as shown in the embodiment, and if gripping and pouring can be performed easily, it is appropriate. Good in place. Further, when the pipe is adhered to the gripping opening 6, an appropriate means can be used, depending on the materials of the two, such as adhesive or heat welding.

[0012]

According to the present invention, similar to the previously proposed closed container, the container has a simple structure constituted by sealing the synthetic resin film 1a, and the liquid contents can be stored in the cardboard box as it is. It can be taken out and taken out from the cardboard box when the remaining amount is small, and can be poured out, and a squeezing (handling) action can be added if necessary.

In particular, according to the previously proposed sealing, since the grip portion of the container is made of a synthetic resin film,
In the suspended state with the grasping opening of the grasping portion, the synthetic resin film bends and becomes wrinkled, and the phenomenon that it becomes a thin string and bites into a finger occurs, but according to the present invention, there is shape retention. By mounting the finger protection member 7, a soft gripping surface that hits the fingers is provided, and even if the remaining amount is relatively large and heavy, a comfortable hanging grip state is obtained, and it takes a relatively long time. The squeezing and pouring out of the product can be easily performed. This is true not only in the squeezing work but also in the case of simply carrying the container.

When an annular plate-shaped member is used as the finger protection member 7, the shape of the grip opening 6 can be maintained, and the fingers can always be inserted reliably and easily, which facilitates gripping. Become. When a pipe is used as the finger protection member 7, when the pipe has a gentle curved surface, the contact with the finger becomes softer, and a long time grip or a large amount of contents remain. When gripping, the fingers can be gripped in a state in which no unnatural local force is applied to the fingers and the fingers are not painful.

Further, since the slit 7a is formed on the pipe so that it can be fitted into the grip opening 6,
The mounting is extremely easy and easy to handle, and the above-mentioned remarkable gripping action can be obtained with a simple structure.

Further, when the pipe is fixed to the grip opening 6, a stable mounting state of the pipe can be obtained, and the grip opening 6 is used in the squeezing work and the carrying work in the suspended state.
It does not come off easily. Further, the finger protection member 7 is composed of a pipe having a slit 7a extending in the longitudinal direction thereof, and a plate-shaped body or an annular plate-shaped body adhered to at least one side surface of the handle opening 6. When the pipe is fitted into the annular plate-like body, the gripped state is more easily stabilized, and the pain on the fingers is reduced.
