A sprayhead (1) for use with an aerosol container (2), comprising a chassis (3) capable of firm attachment to said container (2); a rotatable circular collar (4) located largely around and in close proximity to the chassis (3); and a spray channel (8) and associated actuator button (39), said spray channel (8) being designed to pass through a central aperture (13) in the chassis and being connectable to the central valve stem of an aerosol container (2) with which the sprayhead (1) is designed to be used; the circular collar (4) being rotatable between a first position in which a holding feature (33D) of the collar (4) interacts with a holding feature (15D) of the chassis (3) and a second position; the sprayhead (1) being inoperable when the circular collar (4) is in its first position and operable when the circular collar (4) is in its second position; the holding features (33D) providing rotational resistance to movement between the first and second positions; the circular collar (4) further comprising a projection (33D) which interacts with a non- rotating feature (15D) to produce an audible signal when the circular collar (4) is rotated to and from its first position and to and from its second position. |
