Abstract
A membrane for a cover for closing a container having the general form of a cylinder and being compressible in the direction of the axis of the cylinder. The membrane comprises two mutually parallel, generally flat parts arranged to move axially in relation to each other guided in the movement by guiding elements; resilient element arranged to generate a counterforce between the flat parts during compression of the membrane in the direction of the axis; at least a first and a second electrical contact device operated by the axial movement between the circular parts, the combined electrical settings of which contact devices will carry information about the compressions and decompressions of the membrane and elements for presenting the settings to the outside of the membrane. A cover comprising such a membrane and use thereof are also described.
