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: There is described a modular cabinet for storing and driving stirrer cans containing liquids, the modular cabinet comprising a bottom stand on which at least one cabinet module is mounted, and a motion transmission system constituted by driver transmission elements and by driven transmission elements, each cabinet module being made up of two upright elements and a mechanical shelf for supporting and driving stirrer cans. The driver transmission elements of the motion transmission system are disposed outside said mechanical shelf and are independent thereof, and the mechanical shelf contains only the driven transmission elements.

Abstract: A driving head for a stirrer can is provided. The stirrer can includes a cover with a rotatable plate having upwardly projecting fingers and further includes a stirrer inside the stirrer can. The driving head is mounted beneath a hollow shelf, includes a driven shaft and a blade fixedly connected to the driven shaft. The blade engages the fingers for driving the stirrer inside the stirrer can. A swan-neck shaped body having an upper portion, connected to the shelf, and a lower portion is provided. The lower portion of the body comprises a grip for engaging the rotatable plate of the stirrer can. The driven shaft projects through the upper portion of the body. A device for preventing rotation of the stirrer can is provided.

Abstract: Driving member of the mixing centers are driven permanently by a transmission element for driving a coupling member with which a complementary coupling member of a stirring pot is brought in engagement. Each driving member comprises a pulley connected to the driving shaft of a coupling member by a resilient means associated with protrusions interposed between the shaft and the pulley, said protrusions disconnecting the shaft from the pulley when there is a unacceptable excess of a retaining torque applied to the coupling member.
