Abstract
Perfections in aerosol valves, characterized in that they comprise a closing gasket with an opening, and a tubular valve stem extending through it, and because the tubular valve stem extends into a thrust cup by means of means elastics to form a closure fit with the underside of the lining around the opening, and the stem has a slot through its wall, which extends above the sealing cup which is normally closed by the closure lining, the arrangement being such that the depression of the valve stem displaces the sealing cup of the gasket and exposes the above-mentioned groove above the sealing cup to allow the material under pressure to circulate through the valve assembly.
