[Industrial applications]

 The present invention relates to a liquid storage bag.

[0002]

[Prior art] [Problems to be solved by the device]

 Containers for storing liquid cosmetics and the like are formed of thick synthetic resin having shape-retaining properties or glass, and conventionally, the contents are generally discarded after use. However, along with the deterioration of the waste disposal situation in recent years, it is desired to reduce the amount of waste as much as possible.

From such a background, recently, the contents are stored in a simple refill bag to refill the contents, 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, when the liquid is hermetically stored in the bag made by adhering the inner surfaces of the plastic film to each other, For example, a part of the corner of the bag is cut and removed to open the storage portion, and then the storage portion is pressed to pour out the contents from the opening portion.

However, since a bag of this kind is opened by cutting and removing the corner portion, the opening portion is too small and it takes time to pour out, or it is too large and comes out of the container mouth for injecting the liquid, or However, if the cutting angle is bad, the liquid will be poured in an unpredictable direction, and since it must be poured from above the mouth and neck of the container to be filled, it is difficult to fill the container accurately, etc. It has the drawback of being difficult.

The present invention proposes an excellent liquid container that overcomes the above-mentioned drawbacks of the prior art.

[0006]

[Means for Solving the Problems]

 In order to solve the above problems, the bag of the present invention is made by fixing the inner peripheral surfaces of a synthetic resin sheet having a predetermined shape to each other by an appropriate fixing means such as fusion, and at the same time, a storage section 4 for sealing liquid inside is formed. A liquid storage bag comprising a bag body (2) provided and a pouring plug (3) fixed to an upper edge portion of the body (2), wherein the pouring plug (3) is an opening portion opened at an upper edge portion of the bag body (2). 5. An elliptic cylinder-shaped pouring tube forming portion 6 in which a base end outer peripheral edge portion is fixed to an inner edge portion, and a pouring tube forming portion 6 front end surface are integrally connected to each other via a thin-walled bending break portion 7. And the fixing ring forming portion 8 having an elliptic cylindrical shape, and the fixing ring 8A separated and formed on the outer surface of the spout 6A having the tip opening formed by breaking the breaking portion 7 to separate the fixing ring 8A. Cylindrical spout barrel 6A can be formed by fitting the two in a state where the longitudinal directions are perpendicular to each other. Configuration was.

[0007]

[Action]

 From the state of FIG. 1 or FIG. 4, the breaking portion 7 is bent and cut to separate the fixing ring forming portion 8, and the breaking portion 9 is bent and cut to separate the closing plate 10 or the cap forming portion 11 from the storage portion 4 A pouring tube portion 6A communicating with the inside and a fixing ring 8A are formed. The dispensing tube 6A is opened at the tip due to the separation of the fixing ring forming portion 8 and expands into a cylindrical shape by fitting the fixing rings 8A on the outer periphery thereof in a state where their longitudinal directions are orthogonal to each other. Then, the bag body 2 is squeezed, so that the liquid can be poured out.

[0008]

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

1 to 3 show an embodiment of the present invention, in which 1 denotes a liquid storage bag. The bag 1 is composed of a bag body 2 and a pouring plug 3.

The bag body 2 is obtained by cutting a sheet such as a synthetic resin single sheet or a laminated sheet of synthetic resin sheets, a laminated sheet of a synthetic resin sheet and paper, etc. into a predetermined shape, The bag is made by fixing it by an appropriate fixing means such as fusion or adhesion, and has a storage part 4 for storing the liquid therein. In the present invention, two large sheets having a vertically elongated rectangular shape and a small sheet having a horizontally elongated rectangular shape having the same width as the sheets are prepared. It is a known form called a so-called standing pouch in which a bag is made by fusing in a belt shape so as to have a vertically long rectangular shape. Can be adopted. In addition, a bag formed by folding one rectangular sheet in half and fusion-bonding the three-sided opening portions, or a form formed by stacking two rectangular sheets and fusion-bonding the four sides, etc. A bag can also be used.

In this embodiment, an opening 5 is formed by obliquely opening the upper corner portion of the bag body 2, and the pouring plug 3 is bonded between the front sheet and the rear sheet of the opening 5 portion. The liquid storage bag 1 is formed by being fixed by an appropriate fixing means such as fusion bonding.

The spout plug 3 is made of an elastic synthetic resin integrally formed by injection molding or the like, and has a thin-walled thin-walled end at the tip of the elliptic cylindrical spout tube forming portion 6 which becomes the spout tube 6A when in use. The elliptic cylindrical fixing ring forming portion 8 which becomes the fixing ring 8A at the time of use is integrally extended through the bending breaking portion 7, and the thin portion bending breaking portion 9 is further provided at the tip of the forming portion 8 through the bending breaking portion 9. A blocking plate 10 that closes the opening of the tip of the ring forming portion 8 is extended.

Then, the base end outer peripheral edge portion of the spout tube forming portion 6 is fixed to the inner peripheral edge portions of the front and rear sheets of the opening portion 5 in a belt shape and integrally fixed to the bag body 2, whereby the storage portion is formed. The inside of 4 and the inside of the spouting cylinder forming portion 6 are communicated with each other, and the opening 5 can be liquid-tightly sealed by the spouting plug 3. Further, when the fixed ring forming portion 8 is separated at the breaking portion 7, the tip of the formed pouring cylinder 6A is opened, and the separated fixing ring forming portion 8 breaks the tip closing plate 10. When cut and removed at the portion 9, it becomes an elliptic cylindrical fixed ring 8A. By fitting the ring 8A to the outer periphery of the pouring tube 6A while elastically deforming the longitudinal directions thereof in directions orthogonal to each other, the pouring tube 6A It is configured to expand into a cylindrical shape.

FIGS. 4 to 6 show another embodiment of the present invention. In this embodiment, a cap forming portion 11 is extended from the tip of the fixed ring forming portion 8 instead of the closing plate 10. is doing.

The cap forming portion 11 closes the opening at the tip of the fixing ring forming portion 8 and bends the lower surface of the cap top wall forming portion 12 which becomes the cap top wall 12A at the time of use to the tip of the fixing ring forming portion 8. A cap peripheral wall forming portion 13 which is integrally connected via the breakage portion 9 and extends from the peripheral portion of the forming portion 12A to become the cap peripheral wall 13A when used is formed. Then, when separated, it is configured to be closely fitted to the outer periphery of the upper end of the elliptic cylindrical discharge cylinder 6A.

[0016]

[Effect of device]

 As described above, since the bag of the present invention has the above-described structure, the entire spouting plug is relatively flat and unobtrusive before opening, and after opening, the elliptic cylinder-shaped spouting tube is cylindrical by the fixing ring. Since it can be opened in a shape and the size of the opening can be made almost constant, the opening is too large, like the conventional one that cuts and removes the corner of this kind of bag body, It is not too small, and when it is thrown away, it only has a pouring tap, so it can be rolled up into a small size and discarded, and the weight is also small.

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