Abstract

A package includes a container having a neck finish with at least one external thread segment and at least one pair of angularly spaced external lugs disposed beneath the thread segment. A closure has a cylindrical wall with at least one internal thread segment for mating engagement with the external thread segment on the container neck finish and at least one tab extending from the wall for receipt between the lugs to resist removal of the closure from the container neck finish and aligns the closure with the container body. The clockwise-disposed lug prevents over-tightening of the closure on the container neck finish, while the counterclockwise-disposed lug resists unthreading of closure from the container neck finish when the tab on the closure skirt has been received between the lugs. The clockwise-disposed lug that prevents over-tightening of the closure on the container neck finish has a greater radial dimension than the counterclockwise-disposed lug, preferably by being radially thicker than the counterclockwise-disposed lug.
