Description

  The present invention relates to a refill bag container, and more particularly, to a refill bag container that includes a pair of front and rear front film portions, and is formed by sealing and joining at least some peripheral portions of these front film portions.

  In recent years, with regard to synthetic resin containers that contain various liquids and other contents, it has become possible to reduce the environmental burden, and various thin-walled containers have been developed that reduce the amount of resin used. Yes. Further, as containers for storing various detergents, foods, and the like, bag containers for refilling using a pouch, a gusset bag, a pillow bag, etc., including a pair of front and rear film portions made of synthetic resin are frequently used. Refillable bag containers are expensive refills equipped with a discharge mechanism by a pump device, etc., and a dispensing spout by a dispensing spout, etc. The container can be used for a long time without being discarded each time.

  On the other hand, the bag container for refilling by a pouch, gusset bag, pillow bag, etc. is made of a thin film material made of synthetic resin and is rich in flexibility and flexibility. It is difficult to refill the contents in a stable state while preventing spillage through the mouth portion of the refill container. For this reason, the technique which makes it possible to refill the contents in a more stable state from a pouch for refilling to a refilling container is also disclosed (for example, refer to patent documents 1 and 2).

  In the refilling pouches of Patent Literature 1 and Patent Literature 2, a notch for engagement or a curved concave portion that curves in a concave shape is provided at the edge of the peripheral seal portion of the dispensing nozzle portion, and these notches and curved shapes are provided.
