Abstract: The lid with cams for closing a pot or paint etc. has an underside provided with a seal to be clamped against an edge of a rim of the pot by pivoting the cams on the underside of the lid with levers placed on the top side of the lid. At least the rim is coated inside with a friction-sensitive, corrosion-protective material. Each of the cams is connected to the respective lever with a spindle. A spring biases this spindle, and thus the cam, in an upward direction. Each cam is maintained at a distance from the bearing surface of the rim in every positions of the cam except a position in which the cam extends outwardly from the lid (closing position) so as to protect the friction-sensitive corrosion-protective coating of the rim from abrasion.

Abstract: The stirrer lid device is provided with a stirring device carried by a driving shaft extending through the lid via a sleeve. The lid has an underneath portion which defines a groove for a flat and annular sealing gasket having a width selected for compensating manufacturing tolerances between pots various origins. The lid cooperates with means imparting a uniform pressure on the sealing gasket.

Abstract: Each of the modules comprises a base or case with cells been mounted thereon. Each of the cells comprises two vertical panels connected by a plate containing a mechanism for driving coupling members which are complementary to coupling members comprised by the can stirrers. One of the cells at least is provided with a motor reducing unit simultaneously connected to horizontal and vertical movement transmitting units provided for connecting together the motor reducing unit and the various coupling members.
