To prevent inclination, twisting, or distortion with a pressure member or a bellows pump by achieving smooth pressure-pushing operation and returning motion without specially increasing pressure on a thin lid or the pressure member.

The structure includes a container 1, the lid 2 to close the container 1, the bellows pump 4 included in the lid 2 to normally take in air as a spring 3 is restored, and a pressure-pushing member 6 for pressure-pushing operation from above the lid 2. A slide guide 12 is provided to prevent an upper plate 11 of the bellows pump 4 from inclining when the upper plate 11 moves vertically to slide.
