An improved spray through cap assembly (10) comprises separable base (11) and cover parts (13). The base part includes a hollow actuator (17) which is adapted to cooperate with an outlet of an aerosol or the like. The actuator is linked to a fluid flow channel (19) formed by correspond recesses in the base and cover parts respectively and a nozzle outlet (20). Depressing the cover part causes the actuator to actuate the outlet and causes the contents of the aerosol to be discharged through the nozzle outlet via the fluid flow channel. In order prevent accidental discharge, in one embodiment, the base part includes a projecting lip (22) and the cover part includes a nose (21), the lip and nose cooperating in an inoperative position to prevent the actuator actuating the outlet. In a further embodiment, the cover part is formed from two separable parts and the fluid flow channel and nozzle outlet are formed by corresponding recesses in the parts of the cover parts. In this embodiment, the cover part and base part can be separated prior to separating the respective parts of the cover part for cleaning thereby also preventing accidental discharge on cleaning.
