Abstract: A process for the continuous recovery of caprolactam from either solid polycaprolactam waste by depolymerization or from liquid polycaprolactam extraction water from an extraction zone where, in either instance, a caprolactam water vapor mixture is produced and subsequently upgraded in a distillation zone to provide a dilute mixture of caprolactam and water vapor. A minor portion of this dilute caprolactam water vapor is condensed and recycled to the distillation zone. The remaining, major portion of this mixture is compressed and admixed with fresh steam, superheated and passed to either the extraction zone or depolymerization reaction.

Abstract: A can carton having interconnected top, bottom and side walls and end closure panels is provided with a transverse flap formed in the top wall and including spaced parallel side edges and arcuate end slits interconnecting adjacent side edges of the flap, one of the side edges of the flap being defined by a perforated severance line and the other side edge of the flap being defined by a fold line together with stress relieving slits formed in the top and side walls which extend from each arcuate slit into the adjacent side wall. The point of intersection of the stress relieving slit in each side wall with the junction between each side and top wall is offset longitudinally from the severance line defining a side edge of the handle flap. According to a feature of the invention in one form each side edge of the handle flap may be defined by a perforated line which may function as a severance line or as a fold line.
