The transfer device has a means of securing the grip of the lifting device on the lid (14), in the form of an elastic suction pad (11) with narrowing and widening aperture and a suction line (21). The closer (8) can grip the lid and exert suction on it. There is a monitoring device, possibly with a sensor, to monitor the seating of the lid on the lifting device.
