An actuator cap (1; 50) for a fluid spray dispenser comprises a second body part (2) and a first body part (3). The first body part (3) is adapted for connection to a container for the fluid to be dispensed and incorporates a spray channel arrangement (4). The second body part (2) incorporates an actuator button (5) and is rotatable with respect to the first body part (3) from a first position in which the actuator button (5) is non-elevated into a second position in which the actuator button (5) is elevated and capable of depression to cause depression of a part (16) of the spray channel arrangement (4). The actuator button (4) defines a first cam profile (20) along which a first cam follower (22) defined by the first body part (3) travels to cause elevation or retraction of the actuator button (5) when the second body part (3) is rotated. The actuator button (5) also defines a second cam profile (23) that bears against said part (21) of the spray channel arrangement (4) such that when the actuator button (5) is in its elevated position and depressed the actuator button (5) depresses the second cam profile (23) and in turn depresses the part (21) of the spray channel arrangement (4) relative to the first body part (3) to dispense fluid from the container when in use. Preferably, the first and second body parts (3, 2) are individual, integrally moulded components that are snap-fitted together to assemble the actuator cap (1; 50).
