The pressure valve comprises a sealing plug (6) formed of an elastic body or a rigid body and a pressing member (7) formed of an elastic body for pressing the plug (6) against the opening to close the opening. A movable plug (11) supplies the content of the cylindrical body to the dropping portion (9). Preferably the pressing member (7) is selected from a coil spring, a flat spring or an elastic body of natural or synthetic rubber. Preferably the sealing plug (6) of the pressure valve (9) is formed of an elastic body made from natural or synthetic rubber or a rigid body made from fluororesin, stainless steel, polyolefin resin or metal oxide.</p> |
