Abstract

PURPOSE:To provide a liquid receiving bag made of synthetic resin sheet and capable of emptying its contents completely by inserting a hose into the bag in its entirety without using separately a member such as the synthetic resin plate having a connection short pipe end. CONSTITUTION:A liquid outlet opening 12 of a bag 10 is folded double and this folded opening is inserted into a semielliptic, forked end parts of a hose 20. The forked end parts are attached to the bag 10 sealingly all around the periphery of the liquid outlet opening 12, the hose 20 is then passed through a slit 31 of a reinforcing sheet 30, this sheet is folded double on the bag side before the hose reaches the bag 10 to enclose a sealed part 21 of the hose 20 and the reinforcing sheet 30 is sealed in such a manner as to embrace the sealed part 21. In this way the connection end of the hose 20 is so freely deformable that the hose 20 can be connected even to the lowermost part of a side face 11 of the bag 10.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid storage bag for storing liquid substances such as soy sauce.

0002

[Prior Art and Problems of the Invention] As shown in FIGS. 6 and 7, this type of liquid storage bag has a bag body 50 made of a synthetic resin sheet, and an outlet 71 for the contents and a hose from the inside thereof. A synthetic resin plate 70 having 60 short connecting tubes 72 is welded so that the short connecting tubes 72 protrude outside, and the hose 60 is inserted into the short connecting tubes 72 and welded. The reinforcing sheet 80 passed through the synthetic resin plate 70
There is something welded to the plate surface.

However, in such a liquid storage bag, since the synthetic resin plate 70 protrudes around the periphery of the short connection pipe 72, the outlet 71 for the contents is formed at the lowest end of the side surface of the bag body 50. Therefore, the contents remain at the height of the outlet 71. In particular, when the bottom area of the bag body 50 is large, the amount of remaining contents is large, making it extremely difficult to use. Further, the peripheral edge of the synthetic resin plate 70 is connected to the bag body 50.
Leakage may occur due to damage to the bag body 50 caused by contact and sliding.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a liquid storage bag that can drain all of its contents by connecting a hose to the bag body without using the synthetic resin plate described above.

[0005]

[Means for Solving the Problems] In order to solve the above problems, the liquid storage bag of the present invention includes a bag main body having an outflow hole, and a hose having a diameter larger than the outflow hole and having a bifurcated tip. and a reinforcing sheet having a hole through which the hose passes, the bag body being folded in half around the outflow hole and sandwiched between the fork of the hose, This forked part is sealed to the bag body along the entire circumference of the outflow hole, and the reinforcing sheet passed through the hose is folded in half at the outflow hole to cover the sealed part and reinforced to surround the sealed part. A structure in which the sheets were welded was adopted.

[0006]

[Function] The liquid storage bag configured as above has all hose connections made of synthetic resin sheets, so
It can be freely deformed and there are no restrictions on its connection position. Furthermore, the sealed portion between the hose and the bag body is surrounded by the sealed portion of the reinforcing sheet, so that the contents do not leak from the connection portion of the hose.

[0007]

[Embodiments] Hereinafter, embodiments will be explained with reference to the drawings. The liquid storage bag 1 shown in FIGS. 1 to 4 includes a bag body 10 formed to have a certain shape such as a rectangular parallelepiped when filled with a liquid such as soy sauce, and a hose for transferring the liquid inside. 20 and a reinforcing sheet 30, each member of which is made of a synthetic resin sheet.

The bag body 10 is provided with an oval outflow hole 12 at the lowest end of the side surface 11.
The larger diameter hose 20 is folded in half and its tip is cut off into a semi-elliptical shape to form a fork. The reinforcing sheet 30 has an elliptical shape that is one size larger than the tip of the hose 20, and a center portion of the reinforcing sheet 30 has the hose 20 folded in half.
A slit 31 is formed through which the material is passed.

When connecting the hose 20 to the bag body 10, first fold the outflow hole 12 portion of the bag body 10 in half as shown in FIG. , and insert it into the forked part of the hose 20 which is folded in half. Then, after sealing the forked part to the bag body 10 along the entire circumference of the outflow hole 12, the reinforcing sheet 30 is passed through the hose 20, and the reinforcing sheet 30 is folded in half toward the bag body 10 side in front of the bag body 10, and the hose is The seal portion 21 of 20 is covered. Finally, when the reinforcing sheet 30 is sealed so as to surround the sealed portion 21, the connection of the hose 20 is completed.

Liquid storage bag 1 thus formed
Since the connecting portion of the hose 10 is formed only from a synthetic resin sheet, it can be freely deformed and can be attached to the lowermost end of the side surface 11 of the bag body 10, as shown in FIG. Furthermore, since the inner seal portion 21 is surrounded by the outer seal portion 32, it can be said that the structure is extremely leak-resistant.

FIG. 5 shows a hose connection section of another embodiment. This liquid storage bag 2 has substantially the same structure as the previous embodiment, but differs in that a reinforcing sheet 40 having an outflow hole 41 is welded to the inner surface of the bag body 10. By doing so, the strength of the connecting portion of the hose 20 is increased, and the sealing performance of the liquid storage bag is improved.

[0012] In both of the above two embodiments, the connecting portion of the hose 20 is folded in half, but when a liquid is contained, it is pushed open by the pressure, so
There is no particular problem. However, if it is desired to improve the outflow performance, it is advisable to insert a short pipe into the connection part of the hose 20 to secure a flow path.

Further, in the above embodiment, the distal end of the hose 20 is formed into an elliptical shape, but the shape is not particularly limited as long as it is bifurcated. Furthermore, the outflow hole 1 of the bag body 10
2 and the slits 31 of the reinforcing sheet 30 are not limited to those illustrated, and their shapes may be determined as appropriate. Further, the seal may be formed by thermal welding, welding, or by using an adhesive as long as sealing performance can be ensured.

[0014]

[Effects] As described above, in the liquid storage bag of the present invention, since the connecting portion between the bag body and the hose is formed only of a synthetic resin sheet, the hose can be connected to any position on the bag body. Therefore, if the hose is connected to the lowest end of the side of the bag body, the contents can be drained without leaving any residue behind. No more leakage due to damage.
