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.

Abstract: A container (3) closing lid (1) whose top part forms a spout (2) provided with a sliding shutter (4) driven by a spring (5) and controlled in the displacement thereof by a pivotable opening lever, wherein additional elements are provided between the spout (2) and the lever for increasing the spring (5) pressure force and the lid is handled via a grip handle (9). The inventive lid is characterized in that at least one part of the grip handle (9), elements for fixing the lid to the container (3) and elements for permanently pressing the spring (5) are formed in an integral manner with the lid (1) in such a way that an accurate lid (1) having a simplified structural design is obtainable.

Abstract: An installation for filling aerosol receptacles includes a filling station constituted by a housing, at least one cylinder mounted within the housing at a position located above the position for receiving the receptacle, and a controlled jack driving a piston with reciprocating movement in the cylinder to cause liquid contained in the cylinder to pass through the valve of the aerosol receptacle in engagement with the cylinder. The control element of the jack according to the closing and/or locking of the housing door and the shape of the aerosol receptacle, is a same member, this member being, during deformation of the aerosol receptacle driven to move from a position in which it coacts with a supplemental member to control the operation of the jack upon the closing and/or locking of the door of the housing, toward a position in which it inactivates the operation of the jack.
