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.
