Claim:
Dispensing apparatus comprising a housing ( 10 ) for receiving a pressurised container ( 15 ) containing product for dispensation, a series of markings ( 172 ) indicative of quantities of product in the container and indicator means ( 160 ; 200 ) for indicating one of the markings of the series, characterised in that a cylindrical member ( 140 ) is located in the housing ( 10 ), one of the housing and the cylindrical member being provided with a longitudinal slot ( 170 ) and the other of the housing and the cylindrical member having a helical channel ( 141 ) along its longitudinal axis, the indicator means ( 160 ; 200 ) being operatively connected to both the longitudinal slot and helical channel such that rotation of the cylindrical member relative to the housing on actuation of the pressurised container moves the indicator means along the longitudinal axis of the cylindrical member so as to designate a subsequent marking of the series.
