  Among conventional refill containers, pouches are widely used as refill containers because they can reduce the volume of the containers, reduce manufacturing costs, and reduce the materials used. If it is opened, it is usually impossible to seal it. If the capacity of the container for filling the contents is smaller than the capacity of the pouch, the contents must be stored in the refill container. The current situation is that it is difficult to do so.

  On the other hand, thin-walled blow bottles have a cap at the mouth, and even if the contents are left over, it is possible to store the contents by plugging with the cap, and there is no particular problem like a pouch. However, bottle-type containers are not satisfactory in appealing to consumers for sales promotion compared to containers such as pouches in order to give them a sense of cost while reducing the materials used by reducing the thickness. It was.

  Although an attempt has been made to attach a hard pouring pipe to the pouring part of the pouch and attach a cap to the pouring pipe, such a pouch has an increase in the number of components and the addition of manufacturing processes. Since it becomes indispensable, there is a disadvantage that causes an increase in manufacturing cost, and the advantage inherent in the pouch may be impaired.
