Easy-opening container packaging.

摘要

A container packaging having a flanged container (1), and a cover member (2) with which the container is tightly closed by heat sealing at the flange (11) after being filled with a content stuff. This packaging can be easily opened to take out the content by separating the cover member with a human hand force in such a manner that as an end of the cover member (8) is pulled upward, ply separation of a cohesion-destructive plastic layer progresses, or a portion of an outer peripheral threadlike protrusion (3-2) reduced in thickness is broken and ply separation of cohesion-destructive plastic layer thereafter progresses to the position of an inner peripheral threadlike protrusion (3-2a), and a portion of this protrusion reduced in thickness is broken.
