Deformable lid for closing opening in main body has base part next to peripheral part and front rim

摘要

The lid (3) has a peripheral part (4) fitting into the opening (2) in a main body (1). A base part (5) adjoins the peripheral part which faces a holder -rim (6) placed against the front rim (7) of the opening. The lid is deformable between a first shape in which it is inserted into the opening from the front side, and a second shape in which part of the peripheral part and or part of the base part at least partly grips round the opening being closed.
