<p>The actuator button (4) comprises a small collar (5) intended to be fastened to a pressurised container (1), a spraying nozzle (7) and a system (8) of inner ducts capable of connecting the outlet of a valve stem (3) to the nozzle (7). The system (8) of inner ducts comprises closing means (F) capable of closing a passage (15) leading to the nozzle (7) when the angle formed by the axis (A) of the container and the vertical exceeds a predetermined gamma value, which corresponds to a poor position, while these closing means (F) are capable of opening when the said angle becomes less than the predetermined gamma value, which corresponds to a good use position. <IMAGE></p> |
