<p>The fluid dispenser for edible or household fluids and pastes comprises a chamber (7) in a housing (1) which can be connected to a supply container wherein a suction pressure member (15) in the form of a resilient bellows is mounted in the chamber for actuation by a hollow actuating rod (10), this rod being compressed in the rest position together with the bellows by means of a spring (26) located inside said bellows. The bellows (15) are located inside a coaxial sleeve (20, 20) one end of which adjoins the end (16) of the bellows sealingly enclosing the inlet opening (8) of the chamber whilst the other end is firmly connected to the end of the chamber housing the actuating rod (10). During compression and extension and the bellows are safely guided in the sleeve to ensure long service life.</p> |
