高くなるという欠点があった。<Prior Art and its Problems> It has been known in the past to attach a plastic spout stopper to the spout portion of a paper container or the like containing alcoholic beverages, juice, etc. In response, the applicant has proposed a number of liquid paper containers that use a sheet-like member as a pouring spout so that the contents can be easily discharged when opened. One of them is a paper container for liquids that has a fan-shaped backing film on the back of the spout.By peeling off the front film and pulling the center part toward you, the locking parts provided on both sides of the fan-shaped dust film can be removed from the container. A paper container for liquid that engages with a certain position of a spout to form a spout is proposed. However, such a container requires a fan-shaped back film and a front film to form a container, making the structure complicated, the manufacturing process complicated, and the cost high.

By heating at C, the resin on the back side melts, resealing the cut portion and covering the end surface of the paper material. Further, since the spout-forming portion and its periphery are fixed to the surface with a sheet-like member, the cut portion can be covered more reliably.

It is a liquid container that can be easily used. In addition, since the end surface of the paper is covered with the thermoplastic resin on the back side, there is no possibility that the contents will penetrate from the end surface of the paper.
更に一度開封すると紙層の部分が剥離するので開封され
