Abstract: Metal closure components and methods for making the same are provided. The closures may be formed from a metal sheet having a pre-formed polymer film adhered on at least one face. A circular blank may be cut from the sheet, such that the blank may have a circular “raw” cut edge unprotected by the polymer film. The metal blank may then be formed such that the cut edged may be embedded into the film.

Abstract: The present invention relates to closures for mating with containers having a threaded finish. The closures comprise a flange and a skirt downwardly depending therefrom. The skirt includes a deformable element formed of a different material than that of the flange and skirt and disposed on an interior surface. The deformable element inner diameter is smaller than the outer diameter of the container, and accordingly deforms upon mating the closure with the container. The container threads impress threads into the deformable element to form threads on the closure. The deformable element is formed of a suitable material. The closures of the present invention provide for the use of high-speed press-on capping equipment.

Abstract: A press-on, twist-off container assembly of the type that is used, for example, and baby food containers includes a container that has, as conventional, a finish portion with at least one external thread and a closure that is mounted on the container. The closure is of the press-on, twist-off type and includes a panel portion and a skirt portion that together define a generally cylindrical interior recess. As is conventional, a deformable gasket is mounted within the interior recess that has a thread engaging portion that is deformed so as to at least partially conform to the external threads of said finish portion of said container. The thread engaging portion advantageously has a plurality of inwardly extending raised flutes that are circumferentially spaced irregularly about the thread engaging portion. At least some of the flutes are in contact with at least one of the external threads at respective points of contact, and each external thread has a total distance spanned by such points of contact.
