Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid containing bag for containing a liquid material such as soy sauce or mineral water.

[0002]

2. Description of the Related Art Conventionally, as such a liquid containing bag, as shown in FIG. 6, a mounting port member 8 is inserted into an outflow hole 3 of a synthetic resin bag 2 from the inside of the bag 2. , And a hose 4 for guiding fluid is attached to a portion of the attachment port member 8 protruding from the bag body 2.

However, since the liquid containing bag 7 has the mounting port member 8, the contents remain as shown in FIG.

As another liquid storage bag, Japanese Patent Publication No. 6-
There is one described in Japanese Patent Publication No. 98991. As shown in FIGS. 8 and 9, this liquid containing bag has a bag body 2 and an outlet hole 3 formed therein.
Fold back at the center of the bag, and the outflow hole 3 of the folded bag 2
A forked portion of the tip of the hose 4 is adhered to the peripheral portion, and the adhering portion between the hose 4 and the bag body 2 is sealed with a reinforcing sheet 10.

The liquid containing bag 9 is very significant in that the mounting port member 8 is not necessary, but the bag body 2 must be folded back when the hose 4 is bonded, and the liquid bag 9 is manufactured. There are problems that the process is complicated and that the hose 4 can be attached only to the foldable portion of the bag body 2.

Therefore, an object of the present invention is to make it possible to easily manufacture a liquid containing bag in which the hose 4 can be attached at an arbitrary position without using the attachment port member 8.

[0007]

In order to solve the above problems, the present invention comprises a bag body having an outflow hole and a hose protruding outward from the outflow hole portion of the bag body. The inner peripheral surface of the end portion on the side of the bag body was adhered over the entire circumference to the outer peripheral surface of the peripheral portion of the outflow hole of the bag body that was raised outward to form a liquid containing bag. Further, according to the present invention, the liquid containing bag is provided with an outflow hole in the bag body, and an insertion member having a diameter larger than the outflow hole is inserted into the outflow hole from the inside of the bag body to remove the peripheral portion of the outflow hole of the bag body. The outer peripheral surface of the rising side of the bag body is covered with a hose, the inner peripheral surface of the end portion of the hose on the bag body side is bonded to the outer peripheral surface of the rising peripheral edge of the outlet hole, and after bonding, the above It was manufactured by pulling out the above-mentioned insertion member from the outflow hole.

In the liquid containing bag according to the present invention, an outer peripheral portion of the outflow hole of the bag is erected outward by inserting an insertion member having a diameter larger than the outflow hole into the outflow hole formed in the bag. Since the inner peripheral surface of the bag body side end portion of the hose is adhered to the outer peripheral surface of the raised peripheral edge portion of the bag body, the conventional mounting port member becomes unnecessary and the bag body is There is no need to fold back at the center of the outflow hole.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION A liquid containing bag and a method for manufacturing the same according to the present invention will be described with reference to the accompanying drawings.

A liquid containing bag 1 shown in FIG. 1 has a bag body 2 for containing a liquid, and a hose 4 projecting outward from an outflow hole 3 for filling and discharging the liquid, which is formed in the bag body 2. Consists of.

The bag body 2 is made of a flexible synthetic resin so as to have a fixed shape such as a rectangular parallelepiped when containing a liquid.

The peripheral portion of the outflow hole 3 of the bag body 2 is raised outward, and the hose is provided on the outer peripheral surface of the peripheral portion of the outflow hole 3 of the raised bag body 2. The inner peripheral surface of the bag 2 on the side of the bag 2 is adhered over the entire circumference.

The hose 4 is formed of a flexible synthetic resin into a tubular shape like the bag body 2, and guides the liquid when the bag body 2 is filled and discharged.

The hose 4 and the bag body 2 are bonded by the following procedure.

As shown in FIG. 2A, an insertion member having a larger diameter than the outflow hole 3 is inserted into the outflow hole 3 formed at an arbitrary position of the bag body 2 from the inside of the bag body 2. As shown in FIG. 2 (b), the peripheral portion of the outflow hole 3 of the bag body 2 is raised outward.

Next, the hose 4 is put on the peripheral portion of the outflow hole 3 of the bag body 2 which is raised by the insertion member 5.

Then, as shown in FIG. 2 (c), the hose 4 is provided on the outer peripheral surface of the peripheral portion of the outflow hole 3 of the raised bag body 2.
The inner peripheral surface of the end portion of the bag body 2 side is closely adhered over the entire circumference. This adhesion may be performed by an adhesive for synthetic resin, or may be heat fusion or ultrasonic fusion.

After that, the insertion member 5 is inserted from the outflow hole 3 of the bag body 2.
The liquid containing bag 1 is manufactured by taking out.

This liquid containing bag 1 is, as shown in FIG.
Since the inner peripheral surface of the end portion of the hose 4 on the side of the bag body 2 is adhered to the outer peripheral surface of the peripheral edge portion of the outflow hole 3 of the raised bag body 2, the conventional mounting port member 8 is unnecessary. Moreover, since it is not necessary to fold the bag body 2 at the center of the outflow hole 3, the structure is very simple. Therefore, this liquid containing bag 1
It is easy to manufacture, has high production efficiency, and has high reliability against liquid leakage.

Further, in this liquid containing bag 1, as shown in FIG.
As shown in FIG. 2, the reinforcing sheet 6 is laid over the entire circumference of the outer peripheral surface of the end of the hose 4 on the side of the bag 2 and the peripheral portion of the outflow hole 3 of the bag 2 to form the hose 4 and the bag 2. By sealing the leakage of the fluid from the space, the reliability against the leakage of the liquid is further enhanced.

In this liquid containing bag 1, the hose 4 can be attached by forming the outflow hole 3 at an arbitrary position of the bag body 2. Therefore, for example, as shown in FIG. It is also possible to attach. In this way, the fluid discharged from the bag body 2 through the hose 4 has a strong force, and the fluid in the bag body 2 can be discharged to the outside without leaving the liquid containing bag 1 from the other container. Very convenient when transferring all the fluid.

[0022]

[Effect] Since the liquid storage bag and the manufacturing method thereof are as described above, the mounting port member is not necessary, the hose can be mounted at any position, and the manufacturing is simple, so that various needs can be met. It is possible to efficiently produce a liquid containing bag according to the above and provide it to the user.
