A dispenser (1) for delivering aliquots of a liquid product (25) from a reservoir (23), comprising a conduit (33) which comprises one end (34) for receiving liquid from the reservoir, a second end provided with a valve (36) through which the liquid is expelled, and a flexible portion between the first and second ends for being compressed by a compressing mechanism (13) of a dispensing device, thereby to close the conduit at a pinch position (49) in the region of said one end and for then being compressed by the mechanism, between the pinch position and the valve, to create excess pressure of liquid which is thus expelled through said valve, whereby there is provided a narrow opening (45) into which a correspondingly shaped portion (35) of the valve (36) can be securely fitted. <IMAGE> |
