Abstract
In the container, when the cap is capped on the container opening portion, an inner wall surface of a cylindrical sub-fitting wall portion of the cap and an outer wall surface of a large diameter opening portion of the container opening portion closely contact each other, and an outer wall surface of a cylindrical main fitting wall portion of the cap and an inner wall surface of a small diameter opening portion of the container opening portion closely contact each other. In this way, pressing force that is applied to the outer wall surface of the cylindrical main fitting wall portion of the cap from the inner wall surface of the small diameter opening portion of the container opening portion is increased.
