摘要： The present invention relates to a cover (10, 20, 30) with a bi-stable flap mechanism made of a plastic with at least two material components. The cover (10, 20, 30) can be produced in one piece in a multi-component injection moulding technique. At the transition area between the front wall (11, 21, 31) and the edge portion (12, 22, 32), the plastic is sufficiently stiff (preferably on account of greater material thickness) to ensure that an angle p enclosed in the transition area from the side wall (11, 21, 31) to the edge portion (12, 22, 32) remains constant in both bi-stable states. Expansion portions (14, 24, 34) provided in the edge portion (12, 22, 32) ensure that the outer circumference of the edge portion (12, 22, 32) can increase/decrease from one bi-stable state to the other bi-stable state.
