Abstract:
A manual dispenser action comprising a reservoir body (11) communicating with a duct (15) opening outside the reservoir, a piston member (18) being mounted for sliding in a leaktight manner inside the reservoir body, actuator means adapted to make the piston member advance for a forward travel of predetermined maximum extent and to leave the piston member fixed at its position during return travel of the same actuator means to the starting position, said actuator means comprising an operative member rotatable about an axis parallel to the direction of advance of the piston member (18) and adapted to set the quantity of product to be dispensed by means of said rotation, wherein said duct (15) is formed inside a tubular body, is solidly fixed to said operative member and is fitted in a mouth (12) of the reservoir body (11), said duct opening outside a covering element (14) disposed adjacent said mouth (12) and wherein the operative member further comprises one or more flexible teeth (13) fixed to it and extending towards the reservoir body (11), which is provided with a stop member that co-operates with said flexible teeth (13) in order to define, together with the covering element (14), said forward travel of said piston member (18).
