Abstract

Provided is a packaging container that simplifies the opening operation. The packaging container includes a front cover member and a back cover member, which are attached to each other to form a housing space for accommodating an article therein. The back cover member is integrally molded from a sheet-shaped plastic. The back cover member includes an opening portion, which is surrounded by an opening assisting line portion formed in a linear form and opened by tearing the opening assisting line portion when the packaging container is opened. The back cover member is formed so that its surface is recessed at the opening assisting line portion.

Description

technical field

[0001] The present invention relates to a packaging container for storing articles, and particularly relates to a technique for simplifying the unsealing operation thereof. Background technique

[0002] Conventionally, a packaging container having a cover member molded from sheet plastic has been used. For example, in the packaging container of Patent Document 1, both of a pair of cover members (clamshell pullers in Patent Document 1) constituting a storage chamber for storing articles are molded from sheet plastic. The outer peripheral portion of the cover member is welded to seal the packaging container. [Patent Document 1] Japanese Unexamined Patent Publication No. 2001-97444

[0003] However, the above-mentioned conventional packaging containers require complicated work when they are unsealed. For example, operations such as cutting the welded portion of the cover member from the packaging container with scissors or the like, and separating the two cov...
