[Prior art]
Liquid products such as shampoos and detergents were sold in bottles and other containers, but in recent years, simple pouch containers have been filled with liquid products such as shampoos in order to make effective use of bottles and other containers. Liquid products for refilling are sold.
[0003]
Therefore, a consumer first purchases a liquid product filled in a bottle container or the like, but if the consumer uses up the liquid product, he or she may not purchase a new liquid product filled in the bottle container or the like. Instead, a refillable liquid product, which is the same product filled in a simple pouch container, is purchased, and only a liquid product is refilled in an empty bottle container or the like.
[0004]
By the way, the pouch container to be filled with such a liquid product for refilling is simply formed into a bag shape by a flexible sheet such as a synthetic resin sheet in consideration of handling properties and costs when discarding after refilling. When the liquid product for refilling filled in such a pouch container is transferred to a bottle container or the like, for example, as shown in FIG. By cutting off the corners obliquely, a liquid product outlet 91 is formed, and the liquid product is poured into the bottle container 80 or the like from the outlet 91 as shown in FIG.
[0005]
In order to improve the refilling workability, such a refillable pouch container has a form in which a mouth member made of a plastic molded body is provided on the upper part of the container, and a screw cap is externally screwed into a spout of the mouth member. Are provided.
