Packaging container

Abstract

A fitted body comprises a cap 20 made of a rubber elastic material and a body 10 made of a rubber elastic material, and at least the body 20 or the body 10 expands or contracts in accordance with volumetric expansion or volumetric contraction of an article received in a container 1. The container 1 is arranged so as to enable the takeout of the article without any leakage of the article to the outside in a state where the container is restored to an original shape. In the body 10, a thin-film skin 12 is disposed in its bottom to expand and contract. A flange 18 having a notch 19 is disposed near an open end of the body 10. Cord-like projections 17 are disposed in a circumferential direction of a sidewall 11 near the skin 12.
