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 will have to be poured from above the mouth and neck of the container to be filled, it is difficult to fill the container accurately. It has the drawback of being difficult.

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 manufactured by fixing the inner surface of the peripheral portion of a synthetic resin sheet or film of a predetermined shape by an appropriate means such as fusion bonding. A bag body 2 provided with a storage portion 4 for hermetically sealing the liquid, and a tubular portion 8 which is enclosed in the storage portion 4 and has one end tapered in diameter, and a flange 9 outwardly directed from the other end edge. And a nozzle fitting portion 6 having a front rectangular shape, one end of which communicates with the inside of the storage portion 4, is formed on the fixed portion 5 at the corner position of the bag main body 2. Then, the base portion of the tubular portion 8 of the pouring nozzle 3 is closely fitted to the nozzle fitting portion 6 which is opened by cutting and removing the corner portion of the bag body 2.

[0007]

[Action]

 From the state of FIG. 1, the corner of the bag body 2 is cut and removed with scissors or the like to open the nozzle fitting portion 6, and then the pouring nozzle 3 in the storage portion 4 is moved with a finger or the like to form the tubular portion 8 thereof. The base end is inserted into and fitted into the nozzle fitting portion 6, and the tip end of the tubular portion 8 is projected and mounted as shown in FIG. Next, the storage unit 4 is pressed and the contents are poured out from the nozzle 3 into the target container. The pouring nozzle 3 should be moved to the vicinity of the fitting part 6 in advance before cutting the corner part, or if the tip end thereof is fitted to the fitting part 6, the nozzle 3 is fitted. easy.

【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 composed of a bag body 2 and a pouring nozzle 3.

The bag body 2 is formed 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. A bag is made by fixing the inner surfaces of the peripheral portions thereof to each other by an appropriate means such as fusion or adhesion, and forms a bag, and a storage section 4 for storing a liquid is formed inside. In this embodiment, two large films having a vertically long rectangular shape and a small film having a horizontally long rectangular shape having the same width as the film are prepared, and each small film is used as a bottom wall. It has a well-known form called a so-called standing pouch in which predetermined parts of the inner surface of the peripheral part such as the inner surface are fusion-bonded in a band shape so as to form a vertically long rectangular shape in the front. It was constructed 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 formed by folding a single rectangular film or the like in half and fusing the three-way opening portions, 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.

In addition, a nozzle fitting portion 6 having a rectangular shape in the front is formed to project from the fixed portion 5 of the corner portion, one end of which communicates with the inside of the storage portion 4. Further, a cut line 7 that serves as a mark when the nozzle fitting portion 6 is opened is formed on the outer surface of the corner portion by an appropriate means such as printing.

The pouring nozzle 3 is made of a synthetic resin, and is formed by protruding an outward flange 9 from the other end of the cylindrical portion 8 having a tapered tip end. The outer peripheral length of the tubular portion 8 is approximately equal to or slightly larger than the lateral width of the nozzle fitting portion 6 of the bag body 2 so that the tubular portion of the nozzle 3 is attached to the nozzle fitting portion 6. It is configured so that the outer periphery of the eight base ends is closely fitted.

The pouring nozzle 3 is enclosed together with the contents in the storage portion 4 of the bag body 2, and the tubular portion 8 is fitted to the nozzle fitting portion 6 that is cut and opened when the bag is used. It is configured to be used.

If the bag body 2 is made of a transparent material, it is convenient for confirming the existence of the pouring nozzle 3 or mounting the nozzle.

[0016]

[Effect of the device]

 As described above, since the bag of the present invention has the above-described configuration, the liquid can be poured out by the cylindrical nozzle protruding from the nozzle fitting portion, so that the tip of the nozzle is injected into the mouth and neck of the container. It is possible to inject the liquid by inserting it into the container and refill the liquid well without inconvenience such as leakage of the liquid to the outside.

In addition, since the tip of the tubular portion of the nozzle is tapered and reduced in diameter, the nozzle can be easily inserted and fitted into the nozzle fitting portion, and the nozzle fitting portion has a tubular tubular shape. The nozzle is fitted tightly to the outer circumference of the part, and the outward flange is locked to the base end of the nozzle fitting part to limit the projection of the tubular part. There is no risk of it coming off during pouring, and good liquid pouring can be performed.

Further, the nozzle fitted to the nozzle fitting portion is guided to the side surface of the fitting portion in a predetermined direction as long as the nozzle can be inserted and fitted even if the nozzle is cut in a curved direction at the opening of the fitting portion. There is no risk of pouring the liquid in an inconvenient direction.

Further, even when discarded, the number of small nozzles is increased as compared with the conventional bag alone, so the intended purpose of this kind of bag to reduce the weight and bulk of the waste can be sufficiently fulfilled. It is a thing.
