ABSTRACT:
A twist-off can end assembly includes a cylindrical can body having an open end with a rolled flange extending around an exterior surface of the can body at the open end and a shoulder portion joining the open end with side walls of the cylindrical can. A collar surrounds the exterior surface of the can adjacent the open end, the collar including a can mating finish of an inner surface thereof and a closure engaging finish on an outer surface thereof. The collar is seated against the exterior surface of the open end between the rolled flange and the shoulder portion of the can body. A cylindrical closure is provided having a dependent peripheral skirt for operatively engaging the closure engaging finish of the collar. A lid member is secured to the open end of the cylindrical can body by a lid engaging portion of the cylindrical closure. Because of the arrangement described, rigidity is provided to the lip of the can body, the engaging collar results in a better drinking surface, and the cylindrical closure protects the drinking surface of the engaging collar prior to use thereof. Finally, due to the combination, the can body and can lid are formed of standard parts in a conventional and known manner.
