Abstract

(57) [Summary] [Purpose] To propose a refillable liquid storage bag that allows easy refilling of liquids. [Structure] A bag main body 2 which is made of a synthetic resin and has a storage portion 4 for hermetically sealing a liquid therein, and a synthetic resin cylinder 3 fitted to the outer periphery of the main body 2. did.

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. 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 bags are made by adhering the inner surfaces of the plastic film to each other, the liquid is hermetically stored in the bags before use. For example, the corner of the bag is cut and removed to open the storage portion, and then the content liquid is poured out from the opening portion.

However, since the bag of this kind described above is formed of a thin film and is not stiff, it deforms into various shapes due to the weight of the liquid when it is held in the hand, and the direction of the spout is undesired. However, there is a drawback that it is difficult to inject the liquid into the container because the liquid changes extremely or the existence of the liquid is extremely biased at the holding part.

The present invention has been made in consideration of the above-mentioned conventional points, and an object thereof is to propose a refillable liquid storage bag that can be easily poured into a container.

[0006]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the bag of the present invention is made by fixing the inner surfaces of the synthetic resin film or sheet having a predetermined shape to each other by appropriate fixing means such as fusion bonding, and sealing the liquid inside. The bag body 2 has a front rectangular shape and is provided with a storage portion 4 and a cylindrical body 3 made of synthetic resin fitted to the central portion of the outer periphery of the body 2 in the vertical direction.

[0007]

[Action]

 From the state shown in FIG. 1, the corner of the bag body 2 is cut with scissors or the like to open the storage portion 4, and then the liquid is poured into the container while holding the tubular body 3 as shown in FIG. At this time, since the deformation of the bag body 2 is prevented as much as possible due to the presence of the cylindrical body 3, it is possible to easily pour out the liquid.

[0008]

【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 cylindrical body 3.

The main body 2 is obtained 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 surface of the peripheral portion is fixed to each other by an appropriate means such as fusion or adhesion, and is formed into a bag in a rectangular shape on the front surface. A storage portion 4 for storing a liquid is formed inside.

The tubular body 3 has an elliptic tubular shape formed of a synthetic resin, and has a vertical width such that the upper and lower sides thereof project when the bag body 2 is attached to the tubular body 3, and the tubular body 3 is slightly elastic. As shown in FIG. 1, the shape of the bag is fitted to the outer surface of the bag body 2 at the center in the up-down direction.

[0012]

[Effect of the device]

 As described above, the bag of the present invention has the above-described configuration, so that it is possible to prevent the bag body from being deformed into various shapes due to the weight of the content liquid due to the presence of the tubular body. Can be easily poured out.

Further, since the conventional container of this type is simply fitted with the tubular body, there is an advantage that the manufacturing is extremely easy and the cost can be obtained.
