In the liquid storage bag 10 'having a developed bottom structure, if the liquid spout 20' is arranged on the side opposite to the bottom structure, the liquid storage bag 10 'will be stored when the bottom is kept in a standing state and used. As the amount of the liquid that is present decreases, a void is created in the upper part near the liquid pouring outlet 20 ', and when the liquid is poured out, the bottle must be squeezed to remove the air before the liquid can be poured out. In particular, when the liquid volume is very small, liquid pouring becomes more complicated. Further, with such a structure for arranging the liquid pouring port 20 ', it is not economical because it is complicated or difficult to take out the liquid remaining on the bottom side, and sometimes the liquid may be discarded while remaining.

If the liquid squeezed into the liquid remains in the upper portion as it is, the liquid storage bag 10 ′ cannot be stood up after use, so that the liquid storage bag 10 ′ must be returned to the bottom again. That is, when the liquid becomes low, the liquid must be moved in the liquid storage bag 10 'each time it is used.

媒体としても利用できる。According to the present invention, it is possible to provide a liquid storage bag having a deployable bottom structure in which liquid can be easily poured out without leaving any liquid, and the above-mentioned problems can be solved. It That is, according to the present invention, since the liquid pouring outlet is arranged at the bottom portion, the liquid storage bag can be made to stand up even when the liquid content is low during use. Further, since the liquid is always stored so as to be collected in the liquid pouring outlet, which is the liquid outlet, it is not necessary to move the liquid, which is the content, in the liquid storage bag during use or when not in use. In addition, since the liquid spout is arranged at the bottom and the bag has a developed bottom structure, it is possible to easily use all the liquid as the content. Furthermore, it is easier to stand up even a thin film (for example, polyethylene, polypropylene, etc.) than a liquid storage bag made by blow molding, and in the case of high viscosity liquid food such as mayonnaise and ketchup, synthetic resin The material can be reduced to about 1/20, and it can be adapted to the social environment. Further, unlike a liquid storage bag formed by blow molding, since it can be formed of a film body, various types of printing can be directly performed on the liquid storage bag body, and it can be used as an advertisement medium at the time of display.
