<p><P>PROBLEM TO BE SOLVED: To provide a packaging container which softens the stress or load even when a large load is produced on the peripheral wall resulting from application of the stress to the peripheral wall of the container main body through the tension of a film, when the container constituted of a resin sheet having a foamed layer is packaged with a film such as a wrapping film, and can suitably demonstrate a strong supporting force to the peripheral wall section, and wherein the strength of the container main body does not fall. <P>SOLUTION: This packaging container is equipped with the container main body which is formed by thermally molding the resin sheet having the foamed layer. The container main body is equipped with a bottom surface and the peripheral wall which stands up from the outer periphery of the bottom surface. On the bottom surface, a long groove is extended in a direction around the outer peripheral section for the packaging container. At part of the long groove, a bridge having a cross sectional shape which draws a track continuously rising toward the peripheral wall from the bottom surface of the container main body is formed. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
