Abstract: An apparatus adapted to spray into an atmosphere a volatile liquid, the apparatus comprising an aerosol container (12) comprising a liquid-containing vessel with spray-actuating button (11), the aerosol container being fixed to the apparatus by means of a resilient support member (15,16) integral with the container, the container having a rest position, in which the button is in a non-depressed position in relation to a pressure pad (10) fixed within the apparatus, and a spray position, in which the button is in spray-actuating contact with the pressure pad against the resilience of the resilient member seeking to maintain the rest position. The apparatus is simple to construct and operate, and may be constructed such that only appropriate refills can be used.
