Abstract

A valve for dispensing metered doses from an inverted aerosol container has a valve body 2 with an internal metering chamber 4 which is fixed with respect to the valve body and a valve member 8 on a stem 5 which has an outlet passage 18 and a transfer port 19 through which the charge can pass from the metering chamber 4 when the stem 5 is in an operative position. The valve body 2 has a first valve seal 6 with which the valve stem 5 is a sliding and sealing fit. The transfer port 19 is so disposed that when the stem 5 is in the inoperative position the charge to be dispensed cannot pass through it from the metering chamber 4. The valve body 2 has a second valve seal 7 with an opening 10 whose area is sufficient not significantly to impede the flow of material so that the material can freely enter or leave the metering chamber 4 under the effect of gravity. The valve member 8 makes a sealing fit with the seal 7 during movement of the stem from its inoperative to its operative position. <IMAGE>
