Container for dispensing a pressurized fluid including a safety device for release of excessive internal pressure

A container for dispensing pressurized fluids, said container comprising:

• a valve plate (9) including a disk-like portion (12) and an inwardly-directed circumferential fold extending around the disk-like portion (12) and means for dispensing a pressurized fluid contained within the container,
• wherein said means for dispensing is a dispensing valve held in said valve plate (9) and including
• a sealing disk (13);
• a closing body (15) and a membrane (14) in one piece with the closing body under the sealing disk (13), said inwardly-directed circumferential fold compressing and holding peripheral edges of the sealing disk and membrane together and said closing body (15) being provided with at least one throughgoing passage for said pressurized fluid;
• and
• a head (16) with an extension (17) engaged in a blind hole provided in the closing body (15) so that, when said head (16) is depressed, the at least one throughgoing passage in the closing body (15) is unsealed so that the pressurized fluid is dispensed from the container;
• and
• safety valve means for releasing an over-pressure in said container, said safety valve means including at least one ring-like indentation (5) provided in said valve plate (9) by reducing a valve plate thickness of the valve plate (9), said at least one ring-like indentation (9) enclosing a surface of the valve plate and being dimensioned so that rupture occurs at said at least one ring-like indentation (5) when a predetermined over-pressure occurs in an interior portion of the container.
