A container has a valve (2) and a lid (3) which covers the valve (2) from the outside. The valve (3) includes a slit (23) which opens due to outward deformation of the valve (3) when the internal pressure of the body (1) is higher than atmospheric pressure, and which closes due to elasticity of the valve (3) when the internal pressure is approximately equal to atmospheric pressure. The container of the present invention further comprises a pushing structure (4) formed on the inside of the lid (3), this pushing structure (4) being shaped so as to come into contact with the valve (2) when the lid (3) is shut, thereby pushing the valve (2) slightly inwards to open the slit (23).
