A device for dispensing fluid from an aerosol container of the kind which meters discrete doses, operable to dispense the dose when suction is applied. The preferred form of the device has a recess to hold the aerosol with the outlet of the aerosol sealingly secured in a cavity, and a resilient element to seal the outlet from the cavity, which opens into an air duct. The resilient element is held against the cavity outlet by a spring-loaded pivoted arm, and a vane on the arm is located in the air duct, so that suction applied at the outlet of the duct will cause the vane to pivot the arm and release the element. In use, the aerosol is operated to meter a dose, which is held partly in the aerosol outlet and partly in the cavity until suction applied at the outlet of the duct causes the cavity to be opened and the dose dispensed into the duct. |
