[Structure] A bag made of a synthetic resin film or the like by a suitable fixing means such as fusion bonding to have a rectangular shape on the front side, which has an elongated front strip shape, and one end of which is a hollow portion 4 which communicates with the inside of the storage section 2. Is defined along one side by a band-shaped fixing portion 3d, and the hollow portion 4 is cut off leaving the base end to form the nozzle 7.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a refillable liquid storage bag.

[0002]

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

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

From such a background, recently, the contents are stored in a simple refill bag, the contents are refilled, and only the refill bag is discarded. When discarding these bags, it is preferable to reduce the weight and bulk as much as possible. 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 type is cut and removed at the corner to open, the opening 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. 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 of the container to be filled, it is difficult to fill the container accurately, etc. It has the drawback of being difficult to do.

An object of the present invention is to propose an excellent refillable liquid storage bag that solves 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 surfaces of the peripheral portions of a synthetic resin film or sheet having a predetermined shape by appropriate fixing means such as fusion bonding. At the same time, a hollow rectangular portion 4 having a front rectangular shape having a storage portion 2 for sealing the liquid therein and having one end communicating with the inside of the storage portion 2 is formed by a strip-shaped fixing portion 3d. It is configured such that it is defined along one side and that a tearable cutting portion 5 is formed in the fixed portion 3d and that the cutting portion 5 is broken to form an elongated strip nozzle 7.

[0007]

[Action]

 From the state of FIG. 1, for example, after tearing the cut portion 5, the tip is cut and opened with scissors or the like to form a nozzle hole 7, and then the nozzle 7 is inserted into the mouth portion 8 of the container for injecting the liquid, The liquid can be poured out by pressing the storage portion 2.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings.

1 and 2 show an embodiment of the present invention, in which 1 denotes a refill liquid storage bag. The bag 1 is made by cutting a film or sheet (hereinafter referred to as a film) such as a synthetic resin film or a laminated sheet of synthetic resin films, a laminated sheet of a synthetic resin film and paper (hereinafter referred to as a film) into a predetermined shape. The inner surfaces of the peripheral portions are fused and adhered to each other by an appropriate means such as adhesion to form a bag in a rectangular shape in the front, and a storage portion 2 for storing a liquid is formed inside. In the present embodiment, two large-sized films having a vertically long rectangular shape and a horizontally long rectangular small film having the same width as the film are prepared, and each small film is used as a bottom wall. The bag has a well-known form called a so-called standing pouch in which predetermined parts of the inner surface of the peripheral edge of a film or the like are fused in a band shape to form a vertically elongated rectangular shape. Is configured so as to spread in an elliptical shape.

It should be noted that the present invention is not limited to such a bag, but is, for example, a bag in which a rectangular film or the like is folded in half and three-way opening portions are fusion-bonded or the like. It can also be applied to a bag formed by stacking a sheet of rectangular film or the like and fusing the four sides together.

Further, at its upper end, it starts at a predetermined position above the strip-shaped fixed portion 3a on the left side, runs parallel to the strip-shaped fixed portion 3b on the upper side, and is spaced a predetermined distance from the strip-shaped fixed portion 3c on the right side. A band-shaped fixed portion 3d reaching the position is formed, and a front end elongated band-shaped hollow portion 4 communicating with the inside of the storage portion 2 at the right end is defined above the fixed portion 3d.

Further, the fixed portion 3d that defines the hollow portion 4 is formed with a tearable cutting portion 5 that is formed by a perforation that crosses the center of the fixed portion 3d, a thin wire, or the like. Further, a circular fixed portion 3e is formed at the right end of the fixed portion 3d that defines the hollow portion 4 described above, and a circular through hole 6 is formed in the center thereof, and the cut portion 5 is broken. Then, when the nozzle 7 is formed, its base end portion is configured to easily rotate at that portion.

FIG. 3 shows another embodiment of the present invention. In this embodiment, the hollow portion 4 is provided along the left side. Further, the bag of this embodiment shows a state before being filled with the liquid, and therefore the upper end side is open. After filling the liquid from such a state, the upper end opening is fixed by fusion or the like and sealed.

[0014]

[Effect of the device]

 As described above, since the bag of the present invention has the above-described structure, the liquid can be discharged by the nozzle that integrally projects with the base end portion connected to the storage portion. The liquid can be injected by inserting it into the mouth, and good liquid refilling can be performed without any inconvenience such as leakage of the liquid to the outside.

Further, since the nozzle can be formed simply by tearing the cut portion and opening the tip, it is convenient to handle.

Further, since the structure is extremely simple, there is an advantage that manufacturing can be easily performed.

Further, even at the time of disposal, the intended purpose of this kind of bag, which is to reduce the weight and bulk thereof, can be fulfilled similarly to the conventional product.
