<p>The doser has a pushbutton (1), including a dosing chamber (12), enclosed by peripheral (10) and top (11) walls. The doser has a central tube (13) communicating with its expulsion nozzle (14), with a radial hole (15) near its bottom (16). The pushbutton slides axially in a container mounting support (2), in a central opening (21) in the support top wall (20). The support top has an orifice (22), parallel to the central opening, near its periphery. A deformable elastic component (3) is inserted between the pushbutton and support, comprising an extending tube (30), with a closed base (32), shielding the pushbutton and supporting its base. A small collar (33), around the component top, inserted in the support top, seals it and its orifice. The collar top annular groove external rim (35) presses against the pushbutton top internally (17).</p> |
