The lid (2) contains a reinforcing structure (24) between the two hinge pins, and this structure has a support surface (25) designed to rest against a support surface (35) in the frame (3) when the lid is fully open, so that the lid adopts an angle just above 90 deg. Flexible lid sections (27) are provided to allow hinge pins to be fitted into holes in the frame and form a rigid fastening. |
