Abstract
The present invention concerns a unidirectional control valve of the internal overpressure of both rigid and flexible containers. It permits immediate discharge of gases that develop within the container after hermetic closure. The valve in question consists essentially of a membrane 2 with a peripheral edge sealed in a groove 5 of the valve body 1. Discharge occurs through a central hole 3 of the membrane, whereas sealing is optimized by a layer of silicone oil 7 or the presence of two joined rings 10 and 11 that penetrate the elastic body of the membrane. <IMAGE>
