Abstract
A dispenser (1) includes a container (3) for the storage of a liquid, a gas cartridge receiving portion (5) for holding a gas cartridge (4) so that the contents of the container may be pressurized by gas in a gas cartridge, a dispensing arrangement for dispensing the liquid as a spray. The dispenser includes an activator (13) for moving a gas cartridge so that the gas cartridge is in position to pressurize the container, and an inhibitor (17) which inhibits movement of the dispensing arrangement. The activator is associated with the inhibitor so that movement of the inhibitor from the first to second inhibitor positions causes the activator to move the gas cartridge so that the gas cartridge is in position to pressurize the container.
