Abstract
A molded plastic drinking sleeve for push-on assembly to a neck portion of a container according to a typical embodiment includes an annular body formed by an annular sidewall having a uniform taper from a first open end to an opposite second open end, the annular sidewall defining an open interior. The annular sidewall further includes a series of external threads and a roller abutment at the base of the threads for stopping the roller equipment used to help fabricate a metal closing cap that is designed to thread onto the plastic drinking sleeve. The cooperating metal container that receives the drinking sleeve includes a portion that is curled over the upper edge of the drinking sleeve. A free edge of the curled portion is embedded into the plastic of the drinking sleeve.
