Claim:
1. A container comprising: a releasable metal closure including an end wall and a depending skirt, the closure having an annular layer of sealing compound on an inside surface of the end wall adjacent the skirt; and a glass container body comprising a neck with an annular sealing surface, the neck defining a circular opening of the body, the sealing surface defining a localized protrusion or recess, the sealing surface being adapted to form a sealing interface with the annular layer of sealing compound such that when the closure is in a closed position on the container body, the localized protrusion or recess provides a discontinuity in the annular sealing interface; wherein a seal is made by a partial vacuum formed in an interior of the container during processing without mechanical engagement between the closure and the container body; and whereby the container is configured such that relative rotation of the closure and the container body from the closed position creates a venting path proximate the discontinuity from the interior of the container body to an exterior of the container so that the seal is broken.
