The distribution head (1) is integral with a valve flap (3) of a valve (4) intended to be fixed to a housing containing the product to be distributed. The head is provided with a movable cap (11) presenting a clearance (13) facing the distribution orifice (9). A spring (12) is mounted between the cap and the head. The cap is provided with a flexible blade (17) of which the bent extremity (20) obturates, when at rest, the distribution orifice. When pressing the cap (11), the flexible blade (17) clears the distribution orifice (9) before the opening of the valve. Inversely, when relieving the pressure, the cap goes up again after closure of the valve and the flexible blade (17) closes the distribution orifice. |
