ABSTRACT:
The container for dispensing pressurized fluids includes a container-closing valve plate and a dispensing valve mounted in the valve plate. The dispensing valve includes a sealing disk (13); a closing body (15) and a membrane (14) in one piece with the closing body under the sealing disk (13), an inwardly-directed circumferential fold of the valve plate compressing and holding peripheral edges of the sealing disk and membrane together and the closing body (15) having at least one throughgoing passage; and a foam head (16) with an extension (17) engaged in a blind hole provided in the closing body (15) so that, when the foam head (16) is depressed, the at least one throughgoing passage in the closing body (15) is unsealed so that the pressurized fluid can flow through it. A safety valve device is provided for releasing a container over-pressure including at least one ring-like indentation provided in the valve plate by reducing a valve plate thickness and dimensioned so that rupture occurs when a predetermined over-pressure occurs in an interior portion of the container.
