Abstract: Device for filling an aerosol container with a liquid using in particular a filling arrangement equipped with a pusher element (12), includes a cup designed to accommodate the liquid for filling the aerosol container, this cup being provided on its bottom with an injection opening adapted to the valve of the aerosol container, a piston head (7) acting by pushing on the filling liquid contained in the cup for transferring it from the cup to the container. The piston head (7) comes in the form of a scraper in continuous contact with the inside wall of the cup during the transfer operation. The piston head (7) is shaped to work with the cup after transfer to keep the piston head (7) within the cup to form an airtight wall that retains the residual liquid that has not been transferred within the cup.

Abstract: The invention relates to a precision cover (1) with a spout (5) for closing a container of liquid or particulate product of the type in which the top of the cover forms a spout (5) with a sliding seal (2) that is acted upon by a spring (4) and whose motion is controlled by a pivoting opening lever (3). This cover (1) is characterized in that the pivoting opening lever (3) controls at least two different modes of operation of the sliding seal (2), one in which, for a given angular shift of the control lever (3), the seal (2) is moved by a low value relative to the opening of the spout (5), and the other in which, for the same angular shift of the control lever (3), the sliding seal (2) is moved by a higher value relative to the opening of the spout (5) so as to allow the operator to meter the flow rate of the container's contents with very high precision in the first mode and with a high value of opening in the second mode.
