A plastic drinking cup which is integrally connected with one or more elastic closures for the open ends of bottles and/or openings in the top walls of metallic or plastic cans. A closure can be provided at the inner side or at the outer side of the bottom wall of the cup, at the inner side or at the outer side of the tubular wall of the cup, or at the inner side of a transverse wall which is inwardly adjacent to the bottom wall. The closure can constitute an integral or a separable part of the cup, and the latter can be provided with a relief valve to allow for a reduction of pressure in the interior of a bottle or can whose open end or opening is sealed by the closure. The cup can carry two closures, one with a concave internal surface to sealingly engage with and to swivel relative to the partly spherical external surface of a bottle and the other for a can. Each closure can be manually applied to or disengaged from the bottle or can.

A multiple-purpose vessel for application to the open end portion of a container whose open end portion has a partially spherical external surface, comprising a drinking cup; and at least one closure for the open end portion of the container, said cup having a bottom, and said closure being provided on said cup in the region of said bottom and including a cap which is arranged to overlie and surround the open end portion of the container and has a concave, partially spherical internal surface substantially complementary to the external surface of the container, said cap consisting at least in part of an elastically deformable material and being designed for application to the open end portion of the container by snap action so that said surfaces are in sealing contact with one another to prevent spillage of the contents of the container, and said cap having a section which is disposed on the side of said internal surface remote from said bottom and diverges outwardly in a direction away from said bottom so as flare away from the container when said cap overlies and surround the open end portion thereof, said section and the complementary partially spherical surfaces of the container and said cap providing freedom for said closure to swivel within limits with reference to the open end portion of the container while sealing contact between said surfaces is maintained.
