Abstract: A dispensing device for dispensing a viscous or liquid product from a fluid reservoir, and having an actuator 1, a controlling member 2, a dispensing member 3, a collar 4 configured to be linked to the reservoir, and an extender 5. The dispensing device configured so that an actuation of the controlling member 2 causes a relative movement of the actuator 1 and the collar 4 thanks to which the dispensing device reversibly switches from a first configuration, in which the dispensing member 3 is unable to be activated, to a second configuration in which the actuator 1 is coupled in translation with the extender 5, so that when the actuator is pushed down 1 it activates the dispensing member 3.

Abstract: A push button for a system for dispensing a product under pressure, the push button comprising an inner nozzle assembly which presents an upstream spout a lower end thereof intends to be mounted on a under pressure feed tube of the product. The inner nozzle assembly comprises a downstream spout which is in communication with the upstream spout and which ends in an outlet for dispensing under pressure the product. The push button comprises an outer body having a skirt which surrounds the inner nozzle assembly and an upper plate which comprises an upper zone for actuating the system for dispensing, the inner nozzle assembly being mounted within the outer body through a sliding guide until reaching a coupling position wherein the upstream spout is centered on first locking means provided below the upper plate and wherein the downstream spout is snapped on second locking means provided on the skirt.
