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.

Abstract: A spray dispenser assembly (1) for the dispensing of liquids suitable for use in clean-room environments comprising (a) a collapsible liquid impermeable vessel (4) having an open end comprising a neck portion (5) provided with a collar (8) that is more rigid than the vessel (4); the collar (8) being adapted to sealingly engage with seal means (12) provided between the extraction means of the spray dispenser assembly (1) and the vessel (4); (b) extraction means for extracting liquid from the vessel (4) and dispensing the liquid as a spray; and (c) seal means (12) arranged in sealing position to substantially seal the vessel to the extraction means and substantially inhibit the ingress of air into the vessel (4); the seal means (12) and extraction means being arranged such that the extraction means is operable to dispense liquid from the vessel (4) whilst the seal means (12) is in a sealing position.
