Abstract: A container houses an absorbent for absorbing a gas such as oxygen, and can house an absorbent which reacts with a gas to expand as well as can house an absorbent which has a small diameter or whose diameter decreases without leakage, while securing air permeation between the inside and outside of the container. An absorbent-containing container has a lid body and a bottomed-cylindrical container main body having an opening in an upper surface which is covered by the lid body and which has a paper layer as an inner layer. The lid body is fitted in the opening with an outer peripheral portion being bent upward and held in contact with an inner layer of the container main body. An upper end portion of the container main body is bent from above the lid body toward the lid body to grip the outer peripheral portion of the lid body.

Abstract: The oxygen detecting composition of the present invention includes a layered silicate, a cationic surfactant, an organic colorant, a reducing agent, and optionally a basic substance. The oxygen detecting composition is suitable for indicating the presence or absence of oxygen or the degree of oxygen concentration by its reversible color change because of its high light resistance, high heat resistance, transparency and translucency.
