Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid filling container for filling liquid products for refilling such as shampoos and liquid detergents, and more particularly to a liquid filling container having excellent contents filling efficiency and transportation efficiency.

[0002]

2. Description of the Related Art For example, liquid products such as shampoos and rinses are sold in a state of being filled in a bottle container having a pump mechanism and having a certain shape retaining property. After the contents were used up, the bottle container was discarded, and a new liquid product filled in a similar bottle container was purchased.

However, the bottle container itself is still usable after the contents have been used up, and discarding such a bottle container wastes resources. In recent years, a pump mechanism and the like have been provided. Refillable liquid products, which are filled with liquid products such as shampoos and rinses in simple liquid-filled containers that have no flexibility (no shape retention), are being sold. By transferring products, bottle containers having a pump mechanism have been continuously used.

[0004] As a liquid filling container for filling such a liquid product for refilling, for example, there is a standing pouch 50 as shown in FIGS. 8 (a) and 8 (b). As shown in the figure, the standing pouch 50 has a pair of front and back exterior sheets 51 formed of a flexible sheet made of a synthetic resin film having heat bonding property, A gusset sheet 52 forming a gusset portion, wherein the peripheral edge of the gusset sheet 52 is heat-sealed to the exterior sheet 51 and the upper edge and both side edges of both exterior sheets 51 are heat-sealed to each other. And is formed in a bag shape.

In such a standing pouch 50, as shown in FIG. 9, the gusset sheet 52 is heat-sealed on both side edges of both heat-sealed outer sheets 51, and a shampoo or a shampoo or the like is opened from the upper end opening. After filling with a liquid product such as a rinse, the upper edges of both exterior sheets 51 are heat-sealed with each other to close the upper end opening.

Further, as another liquid filling container for filling a liquid product for refilling, for example, there is a bottle container 60 as shown in FIGS. 10 (a) and 10 (b). This bottle container 60
As shown in the drawing, a container body in which a lower end opening of a cylindrical body 62 is closed by a bottom 63 and a mouth 64 is formed in the upper end opening of the body 62 by a blow molding method. The container body 61 includes a screw cap 65 that opens and closes an opening 64 of the container body 61. The container body 61 is formed by a blow molding method.

The blow-molded container body 61 has a small thickness and is considerably more flexible than a regular bottle container having a pump mechanism. After the liquid product filled in 60 is transferred to a regular bottle container, it can be discarded in a folded and compact state.

[0008]

As described above, the standing pouch 50, which is a refillable liquid filling container, has a liquid product as a content sealed in a bag-like container formed of a flexible sheet. Since it is in a state of being deformed, the overall shape can be deformed with a certain degree of freedom, and it is possible to stack and pack it, which has the advantage of excellent transport efficiency, but conversely, the shape retention Since there is no port for filling or pouring the contents, it is difficult to fill the contents which are liquid products.

Further, as described above, since the upper edge of the exterior sheet 51 must be heat-sealed after filling the contents which are liquid products, the filled contents overflow during the heat sealing. There is a problem that a certain margin must be secured in the height direction so that the entire container must be large.

On the other hand, the bottle container 60, which is a refillable liquid filling container, has a certain degree of shape-retaining property that can be opened and closed by the screw cap 65, even though the container body 61 has flexibility as a whole. Although the mouth 64 is provided, there is an advantage that it is easy to fill the contents, which is a liquid product. However, when the contents are filled in the bottle-shaped container body 61, a certain degree of shape retention is secured. And
Since the mouth 64 is closed by the screw cap 65, it cannot be stacked and packed in a box, and there is a problem that transportation efficiency is poor.

It is an object of the present invention to provide a liquid filling container which can be easily filled with liquid contents and can be transported efficiently.
