Abstract:
A paper container comprising synthetic resin layers (3, 4) constituting at least the outermost and innermost surfaces of a laminated structure using paper as a base material (1), the base material (1) being formed with a through-hole (2) serving as a liquid take-out port, wherein the paper container is of laminated construction in which the through-hole (2) is covered from inside by a laminated body of at least two layers in which the synthetic resin layer (4) or (10) and a thin paper layer (8) are integrated. The rigidity of the thin paper layer (8) is imparted to the synthetic resin layer (4) or (10) in which the thin paper layer (8) is integrated, whereby the elongation of the synthetic resin layer (4) or (10) is suppressed to facilitate the piercing of the through-hole (2) with a straw or the cutting-off of the through-hole (2).
