Abstract
The invention relates to a dispenser for dispensing viscous liquids, which dispenser is designed to be mounted on a container; said dispenser being characterized in that it comprises a bowl ( ) whose bottom is provided with an inlet orifice ( ) equipped with a valve ( ), and whose top is closed off by a piston ( ) that is urged back into its high position by a spring ( ) and that co-operates with the inside wall of the bowl to define a metering chamber ( ), the wall of said chamber including an annular zone, all or part of which is elastically deformable so as to act, under the effect of the pressure generated inside the chamber ( ) to release a passageway (P) via which the liquid can be removed, which passageway opens out peripherally to the outside.
