Abstract:
A device for dispensing a fluid substance, comprising:a container (1) in which the substance is contained, said container being provided with an opening,an element (2) movable between a rest position in which it closes the opening of said container and an actuated position,means for connecting the inside of the container to an expulsion channel (10) for expelling the substance,an actuator member (6) for moving said element towards its actuated position in which said element slides in a sealed manner inside said container to expel the substance via said expulsion channel,a passage (3) defined in said element connecting the inside of the container to said expulsion channel,sealing means including a closure member (5) which, in the rest position of the element, co-operates with the element to close said passage in a sealed manner and to establish a high degree of frictional interference between the element and the container to hermetically close the container, anddisplacement means (7) included with the actuator member for displacing said closure member to open said passage and reduce the interference between the element and the container so that the element can slide in the container towards its actuated position with a low degree of friction.
