Claims

[Scope of utility model registration request]

A container is formed from a container material made by laminating polyethylene layers on both sides of a three-layer paper material with a paper layer with a low degree of bonding in the center, and an arbitrary shape is cut from the inside of the container to half the thickness of the paper. A half-slit line for forming an opening is provided, and a half-slit line for forming a bell-shaped peeling funnel-shaped part reaching more than half of the paper thickness is added from the outer surface of the container, surrounding the half-scoring line for forming an opening, and on the lower side thereof. A paper container with an opening mechanism, characterized in that the funnel-shaped portion extends to both ends of the folded line.
