Abstract:
A valve (10) for dispensing metered doses from a pressurized dispensing container (17) has a valve cup (13) attached tothe container. A valve housing (11) fixed to the valve cup has within it nested components (30, 31) the inner one of which defines a metering chamber (16). A valve stem (12) slides through seals (14, 15) one of which is trapped between the valve cup (13) and the inner nested component (30). The other seal (15) is trapped between the nested components. The valve stem is urged into an inoperative position by a spring (60) located within the valve housing but outside the metering chamber. The inner and outer nested components have unequal numbers of castellations (41, 42) formed in their edges around the valve stem to permit flexing of the seal (15) during filling of the container.
