Beschreibung
Zusammenfassung:	A pressure pad suitable for use in the heat sealing of a substantial universe of bottom-panel folding designs for closing the bottom of a carton or container. This new pressure pad includes a pattern of sculpting of that surface thereof which is presented to the infolded panels of the bottom of a laminated paperboard carton thereby providing a pressure pad that is substantially universal with respect to its ability to repeatedly effect the desired heat sealing of a plurality of geometrically differing combinations of bottom panels defining the bottom of a paperboard carton.
