Abstract
A dispenser device which has a pumping device, an ejection nozzle incorporating a dispensing orifice, an actuator for activating the dispenser such as a pusher, and a closure system which enables the dispenser device to be closed, thereby avoiding problems such as contamination or drying out of the dispensing substance. The closure system contains a closure element that is resiliently deformable to go between a closed position in which it hermetically closes the dispensing orifice, and an open position in which it opens the dispensing orifice. When the dispensing device is actuated, the closure element is deformed into its open position by a member solid with the ejection nozzle or the ejection nozzle, and the closure element returns resiliently into its closed position after the dispensing device has been actuated.
