发明名称 PAPER CONTAINER
摘要 A paper container has synthetic resin layers (3) and (4) constituting at least the outermost and innermost surfaces of a laminated structure with paper as a base material (1), the base material (1) being provided with a through-hole (2) serving as a liquid take-out port, in which the paper container is of laminated construction in which the through-hole (2) is covered from inside by a layered material of at least two layers made of an integration of the synthetic resin layer (4) or (10) and a thin paper layer (8). The rigidity of the thin paper layer (8) is imparted to the synthetic resin layer (4) or (10) with which the thin paper layer (8) is integrated. This suppresses the elongation of the synthetic resin layer (4) or (10) to facilitate the piercing of the through-hole (2) portion with a straw or the cutting-off of the through-hole (2) portion. <IMAGE>
