A device for dispensing doses of viscous products comprises a sleeve (2) containing the product (3) to be dispensed; a duct (4) for discharging the product (3); and a mechanism for the dispensing of the doses comprising: a piston (9) sliding in the sleeve (2) and a stem (7) carrying a rack (8) extending in the sleeve (2) and passing through the piston (9). The stem (7) passes, as a result of the actuation of a push button, from the rest position towards a position wherein it is displaced in relation to the sleeve (2), the push button being pushed back in the return direction by a spring (11). The piston (9) carries a catch engagement element (61) causing it to engage with the rack (8) solely for causing the rack to advance towards the duct (4). In order to facilitate the actuating motion, the sleeve (2) is disposed in a cover barrel (5) to which the stem (7) is fixed, the bearing surface of the sleeve (2) projecting from the barrel (5) constituting the actuating push button. <IMAGE> |
