A dispenser bottle assembly 12 comprises a dispenser bottle 24 which includes a base (30, Fig 2) and a projection (62, Fig 2) extending outwardly from the base, an externally threaded collar 28 mounted for rotation about the projection, and a drive member 26 mounted about the projection between the collar and the base of the bottle. The threaded collar 28 is received in a threaded recess 18 in a mounting base 14 to secure the bottle to the mounting base. Corresponding formations on the drive member 26, the base 30 and the collar 28 allow the collar to be screwed into and out of the mounting base 14 by rotating the bottle whilst allowing a limited degree of rotational freedom between the bottle and the collar so that the angular orientation of the bottle can be adjusted after fitting. |
