Abstract
A device (10) for packaging and dispensing a product comprises a container (12), a moveable piston (16) mounted inside the container (12) and delimiting one compartment (22) containing the product, and a dispensing member (14) mounted on the container (12) and comprising at least one outlet orifice (24) in communication with the compartment (22). The device (10) further comprises a pump system (18) mounted on the container (12) axially on the side opposite to the dispensing member (14) and comprising a push-button (28). Said pump system (18) is configured so that exerting a pressure on the push-button (28) results in a forward displacement of the piston (16) inside the container (12) towards the dispensing member (14) and subsequent releasing of said push-button (28) results in a backward displacement of said piston (16) away from said dispensing member (14).
