Abstract
A carton closure system including a cam having a rear face and a camming surface opposite the rear face, the cam being mounted for linear reciprocation between a position wherein there is applied pressure against partially infolded portions of the end side walls of a carton blank to effect a sealing pressure against such infolded portions and a position wherein no material pressure is applied to the partially infolded end side walls of the carton blank, the movement between such pressure and non-pressure applied positions being facilitated by means of a multi-faceted geometry of the camming face of the cam.
