(54) Fluid dispenser


(57) A fluid dispensing device for dispensing controlled doses of fluid from an inverted bottle (5) into a cistern, each time the cistern is flushed. The device comprises a plug member (17) which is adapted in use to be secured in the mouth of a bottle and in which is formed a product feed tube. One end of the product feed tube (55) opens into the interior of the bottle (5) and the other end defines an air trap (57). A cap member (1) is secured to the bottle (5) over the plug member (17) and between them they define a chamber which is open to the air trap (57) end of the product feed tube (55), a siphon (15) connecting the chamber to an outlet port (13) in the exterior of the fluid dispensing device and an air vent connecting the chamber to the exterior of the fluid dispensing device at a point above the outlet port (13).
