Abstract
A snap-on/twist off closure (22), a package comprising the closure, e.g., a bottle in combination with the closure is disclosed. The closure includes an upper wall defining an opening and a cylindrical snap on pipe (30) depending from the upper wall. The pipe includes threads designed to mate with external threads on a neck of the bottle. The threads on the pipe and threads on the neck of the bottle pass over each other when the closure is snapped onto the bottle during manufacture. The pipe includes a resistance recess (42) and a guidance recess (70). A bottom rim of the pipe, the resistance recess and the guidance recess are in contact with a forcing element (50) on a shoulder of the bottle and guide the closure into positions permitting unscrewing of the closure.
