Abstract: An inserted lid (1) for a box (2) is formed so that a contact region (5) can be pressed against the inside of the side wall of the box. In the non-inserted state, said side wall is slightly larger than the box opening (4). On insertion of the lid (1) into the box (2), the largest circumferential line of the contact region (5) must fit the inside of the side wall of the box as a result of an elastic deformation of the closure surface (3). To prevent the forces emanating on insertion from the side wall of the box from leading to irreversible deformations, the closure surface (3) has spring properties which are radial with respect to the contact region (5) and permit an elastic deformation of the contact region (5) in the radial direction. To ensure these spring properties, the closure surface (3) has a shape differing from a flat surface, in particular two concentric waves (7) formed constant distances away from the contact region (5) and/or a central vault (8).

Abstract: A device for controllably retaining a liquid to prevent spillage when the bottle is tilted or inverted for positioning the bottle to discharge the container's liquid contents into the intended orifice. The hydraulically operated plug forms an air tight seal with the smooth inner surface of the neck of the container, permitting the container to be inverted and positioned over the intended receptacle without releasing any fluid. Upon squeezing the flexible container, the lid is forced from the container by the hydraulic pressure exerted on the inner surface of the lid, permitting the liquid to pour freely from the container into the intended receptacle. A tether attaching the plug to an exterior location on the container allows the plug to fall clear of the stream of flow while preventing the plug from becoming lost.
