Abstract

See full text

Pressure relief blow out plugs for a container are disclosed as well as methods of using the same. One disclosed method involves providing a glass container that comprises a base and a body extending away from the base. The base includes a wall that defines a pressure relief passage. The method also involves inserting a pressure relief blow out into the pressure relief passage to seal the passage. The plug comprises a first inboard flange extending radially outwardly from the plug body, a stem, and a second inboard flange extending radially outwardly from the plug body and being spaced apart from the first inboard flange by a stem. The first inboard flange includes a first outboard sealing surface that provides an axial seal against the wall of the base of the glass container, and the second inboard flange including a circumferentially interrupted outboard facing retention portion the defines vent gaps.
