Abstract: An aerosol dispenser has a canister to contain a liquid product to be dispensed together with a propellant present at least partly as a gas and valve (10) to control the release of the liquid product from the canister. The dispenser also has a vapour phase tap for introducing a portion of the gaseous propellant into the liquid product as it is dispensed. The invention is characterised in that the dispenser has a flow control means for varying the rate at which the propellant gas is introduced into the liquid product through the vapour phase tape in dependence on the pressure of the contents of the canister The flow control means can be used to reduce the amount of propellant gas bled into the liquid product, particularly when the dispenser is full and the pressure in the canister is high, as a means of conserving the propellant gas.
