ABSTRACT:
An articulated hinged closure includes a lid adapted to be attached to a wide-mouthed container. The lid has a pouring aperture and a peripheral rim surrounding the aperture, which is initially plugged by a sealing member having upper and lower leaves interconnected by an integral articulated connector. The connector is a link having opposed upper and lower ends, and a flexible hinge at either end, the upper of said hinges connecting the link to the upper leaf, and the lower of said hinges connecting the link to the lower leaf. Each of said hinges is designed so that a respective end of the link binds against adjacent structure in such a-way that, as the lid is opened, the upper hinge eventually binds against the upper leaf, causing the lower hinge to pivot and bind againstr the lid and until it pries the plug out of the aperture.
