Abstract
An apparatus for bursting perforations on an article has a retractable burst member and an opposed second retractable burst member that imposes an impact force on the perforations on the perforated lid. Retractable burst members are arranged for vertical movement towards and away from one another in a common plane. The article is positioned in a plane substantially perpendicular to the movement of the burst members so that the burst members can engageably contact the article at the perforations. A separator is used to capture the perforated lid at the burst perforations and then retract for separating the perforated lid from the main portion of the article.
