BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid storage bag.

[0002]

[Prior art]

A container for accommodating liquid cosmetics or the like is formed of a thick synthetic resin or glass having shape-retaining properties, and conventionally, the contents are generally discarded after use. . However, with the recent worsening of garbage disposal, it has been demanded to reduce the amount of waste as much as possible.

[0003] Against such a background, recently, the contents are stored in a simple refill bag, the contents are refilled, and only the refill bag is discarded. Since it is preferable to reduce the weight and bulk of these bags as much as possible at the time of disposal, for example, the liquid is hermetically stored inside the bag made by bonding the inner peripheral surfaces of the plastic film to each other. The storage section is opened by cutting and removing a part of the corner of the bag, and then the storage section is pressed to discharge the contents from the opening.

However, in this type of bag, the opening is too small to cut and remove the corner to open, and it takes time to pour out, or the bag is too large to be removed from the container opening for injecting the liquid. If the cutting angle is poor, the liquid will be poured out in a direction that does not exist, and it will be necessary to inject the liquid from above the mouth and neck of the container to be injected. There is a disadvantage of leprosy.

[0005] Further, once opened, there is a disadvantage that the contents must be kept open unless all the contents are transferred.

The present invention proposes an excellent liquid container which solves the above-mentioned disadvantages of the prior art.

In order to solve the above-mentioned problems, the bag according to the present invention is manufactured by fixing the inner surfaces of the peripheral portion of a synthetic resin sheet having a predetermined shape to each other by an appropriate fixing means such as fusion or the like. A liquid storage bag comprising a bag body 2 provided with a storage section 4 for sealing a liquid therein, and a spout 3 fixed to an upper corner of the main body 2, wherein the spout 3 is a bag body. (2) An outer peripheral edge of the base end is fixed to an inner edge of the opening 5 opened to the upper corner portion to seal the opening 5, and both sides are connected to each other via left and right hinges 9 and 10, respectively, and the center of each is opened. Tube forming portion 6 composed of rectangular plate-shaped front and rear wall portions 6a and 6b provided with front and rear hinge portions 11 and 12 for longitudinally cutting the wall, and a thin-walled bending break at the tip end surface of the discharging tube forming portion 6 Cap top wall forming part integrally connected via part 7
A cap forming portion 8 formed by extending a flat cylindrical cap peripheral wall forming portion 14 from the 13 peripheral edge, and a pouring cylinder 6A formed by breaking the breaking portion 7 and separating the cap forming portion 8 The cap 8A, which is open at the tip and is formed separately, can be tightly fitted to the outer periphery of the upper end of the pouring cylinder 6A.

[0007]

In the state shown in FIG. 1, the break portion 7 is bent and cut to separate the cap forming portion 8, thereby forming a spout cylinder 6A communicating with the inside of the storage portion 4 and a cap 8A as shown in FIG. Dispensing cylinder
6A is opened at the tip by the separation of the cap forming portion 8, and spreads in a rectangular cylindrical shape by bending each of the front, rear, left and right hinge portions 11, 12, 9, 10. Next, if the bag body 2 is squeezed, the liquid can be poured out. On the other hand, the separated cap 8A is tightly fitted to the upper end of the closed discharging tube 6A to close the discharging tube 6A in a liquid-tight manner.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings.

1 to 3 show one embodiment of the present invention, in which 1 indicates a liquid storage bag. The bag 1 includes a bag body 2 and a spout 3.

The bag body 2 is formed by cutting a sheet such as a synthetic resin single sheet or a laminated sheet of synthetic resin sheets, a laminated sheet of synthetic resin sheet and paper into a predetermined shape, and cutting the inner peripheral surfaces thereof. The bag is formed by being fixed by appropriate fixing means such as fusion or bonding, and a storage portion 4 for storing liquid is formed inside. For example, two large sheets having a vertically long rectangular shape and a horizontally long rectangular small sheet having the same width as the sheet are prepared, and a predetermined portion of the inner peripheral surface of each sheet is formed into a band shape so as to form a bottom wall of the small sheet. A known form called a so-called standing pouch in which the bag is formed into a vertically long rectangular shape by fusing or the like, and a structure in which a bottom portion is expanded in an elliptical shape when the liquid is filled therein can be adopted. Further, a bag formed by folding one rectangular sheet in half and fusing the three-sided opening portion or by fusing the four sides by fusing two rectangular sheets and fusing the four sides. Bags can also be used.

In the present invention, an opening 5 is formed by opening the upper corner portion of the bag body 2 at an angle, and the spout 3 is bonded between the front sheet 2a and the rear sheet 2b at the opening 5 portion.
The liquid storage bag 1 is formed by being fixed by appropriate fixing means such as fusion.

The pouring plug 3 is made of synthetic resin integrally formed by injection molding or the like, and is provided at the tip of the pouring tube forming portion 6 which becomes the pouring tube 6A at the time of use, with a thin-walled bent break portion 7 therebetween. A cap forming portion 8 which becomes a cap 8A when used is integrally extended.

The pouring cylinder forming portion 6 connects the pair of front and rear wall portions 6a and 6b, each having a rectangular plate shape, to each other via left and right hinge portions 9 and 10 in a bendable manner. , Front and rear hinges 11, which traverse the center of each wall 6a, 6b,
12 are vertically provided, and the base end outer peripheral edge is fixed to the bag body 2 integrally with the front and rear sheets 2a and 2b inner peripheral edges of the above-mentioned opening 5 portion in a belt shape, and a cap is formed from the break portion 7. When the portion 8 is separated, the hinge portions 9, 10, 11, 12 are bent to open in a square tube shape.

The cap forming section 8 is provided with the above-described pouring cylinder forming section 6.
The lower surface of the cap top wall forming portion 13 which becomes the cap top wall 13A at the time of use is integrally connected via the bent break portion 7 to the tip, and the cap peripheral wall forming portion which becomes the cap peripheral wall 14A at the time of use from the periphery of the forming portion 13 14 is extended, and is configured to be closely fitted to the upper end of the closed pouring tube 6A when separated.

[0015]

[Effects of the Invention] As described above, the bag of the present invention has the above-described configuration. If a cap is attached to the flat dispensing cylinder after opening, the required amount of the stored liquid is poured out and the remaining liquid is discharged. The solution can be preserved in a good condition even if it is left.

Further, the size of the pouring hole is substantially constant by opening the pouring cylinder into a square tube, so that the opening is formed by cutting and removing the corner of the conventional bag body. The part is not too large or too small, and when it is discarded, it has only a small spout, so it can be rolled up and discarded, and the weight can be reduced.

Further, since only a small spout is fixed to the conventional bag of this type, it is easy to manufacture and can be manufactured at low cost.
