Abstract
A package is provided in the form of a container and closure assembly which incorporates a system for providing a positive orientation of the container closure so as to align external features of the closure and container. The container has a neck defining an opening to the container interior, an external screw thread, and a protuberance. The protuberance has generally oppositely facing abutment surfaces and at least one cam surface extending between the abutment surfaces. The closure has a skirt defining an internal screw thread for engaging the container external screw thread. The skirt defines a recess for receiving a protuberance. The recess is defined at opposite ends by spaced-apart engaging surfaces for confronting the protuberance abutment surfaces. The skirt is sufficiently resilient to deform as relative threading engagement is effected between the closure and the container neck to accommodate relative movement of the container neck and closure until the protuberance is received in the recess to prevent relative rotation between the closure and container.
