  • one layer forms a support for the closure element in the open position.
  • the size of the closure element is such that it is completely accommodated in the outer contour of the holding plate both in the closed and in the open position. This is achieved, for example, in that the closure element has a closure surface which is adapted to the opening of the holding plate and has a handle arranged thereon, which closure surface is displaced into the region of the opening of the holding plate in order to produce the closure position.
  • the minimum displacement corresponds to the diameter of the opening of the holding plate.
