Abstract
A multilayer cover has a sandwich design for placement on a drawer of a vacuum drawer device, and the cover allows an evacuation of the drawer interior after sealing against the drawer. The cover has an outer air-tight cover layer and a core layer, recesses molded into the core layer and partly into one of the at least one outer cover layer, and an evacuation channel, a pump, and at least one sensor are arranged therein. The cover is to have a more compact design with a very low height, resulting in a minimal susceptibility to malfunction. This is achieved in that a printed circuit board is arranged on one of the at least one outer air-tight cover layers so as to face the core layer or the at least one outer air-tight cover layer is designed as a printed circuit board on which the core layer lies and on which the electric components integrated into the cover are mechanically held and are electrically connected.
