Abstract (en)
It comprises a lower part (1) and an upper part (2). The lower part (1) comprises a body (4) housing the metering and expulsion device for the product. A package (3) containing the product is arranged in a housing (5) which communicates with a lower chamber (7). The chamber (7) is in communication with a first chamber (8). One end of a piston (11) is displaced in a leaktight manner inside the chamber (8). The hollow piston (18) is closed at its second end by a screwed plug (16) emerging into a bore (17). The bore (17) ends in a tubular projection (22) capped by a sleeve (23) whose lower end is equipped with a slot (24). A lever (25) articulated about a pin (26) is connected to the hollow piston (11). The tubular projection (22) is equipped with a countersunk part (27) and in the same horizontal plane the dispenser is equipped with a horizontal extension (28). At the end of the expulsion phase, the projection (28) crushes the sleeve (23) which reassumes its initial shape during the return phase, creating a reduced pressure in the sleeve (23) permitting suction of the drop of product remaining outside. <IMAGE>
