Abstract

The dispenser is used for spraying a liquid, for example a perfume. The dispenser (10) is mounted on the neck of a container (11) by means of a screwed ring (12). A trigger (14), connected to a pusher (16) via a flexible articulation (15), actuates a flexible diaphragm rane (17). The diaphragm defines a pump chamber (20). The upper wall (23) of the chamber (20) cooperates with the adjacent part of the diaphragm (17) in order to form an outlet valve (21). An inlet ball valve (26) communicates with a plunger tube (27). When a partial vacuum is created in the container by pumping the liquid, a seal (31), provided for this purpose, is deformed and enables atmospheric air to enter the container (11) via a passage (32c) in order to replace the pumped liquid. <IMAGE>
