Initially the hinge element extends inwardly from the position along the first wall at a distance from the opening, connects to the lid and forms the first link and the second link extending towards the opening. Third link located between them extends from the opening. First link is connected to the third link by a first curved portion having a first inner radius and the third link is connected to the second link by a second curved portion having a second inner radius that is smaller than the first inner radius.
