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 int...
[ What is claimed is:] [1.] A container comprising:a container body;a valve mounted to the container body at an opening of the container body, said valve including a slit which opens by outward deformation of said valve when an internal pressure of said container body is higher than atmospheric pressure, and closes due to elasticity of said valve when the internal pressure is approximately equal to atmospheric pressure;a lid which covers said valve from the outside; anda pushing structure which is shaped and positioned so as to come into contact with sai...
