Abstract
A dispenser for viscous products, including: a container for a product, a sealing cap designed to be screwed onto the container, a pipette, and a piston capable of causing a suction of the product into the pipette, the dispenser being arranged such that, when the cap is screwed onto the container, the unscrewing of the cap in the direction of opening of the dispenser causes, by itself, a movement of the piston producing the suction.
