Title: Plastic closure and related container finish

Abstract: This relates to an improvement in the neck finish of a container and skirt of a cooperating closure to eliminate or substantially reduce squaring which exists in present closure-neck finish arrangements. The neck finish is constructed so as to control the torque required to apply the closure after it has been seated, thereby holding to a maximum the pressures which normally effect squaring. At the same time, the neck finish is provided with a supporting surface engageable by the closure skirt so as to permit supporting of the closure skirt against the undesired squaring.
