ABSTRACT:
The paperboard carton has a material severing edge which is located on an end edge of the blank from which the carton is formed and is used to sever material from a roll thereof disposed in the carton. The material severing edge is preferably located at the lower front corner of the carton and projects beyond the plane of the front wall of the carton. The material severing edge is preferably a plastic strip secured to the paperboard and having a cutting surface formed concurrently with the formation of the end edge of the blank on which it is mounted. The paperboard backing the cutting surface is preferably substantially removed from beneath the cutting surface so that the latter consists essentially of all plastic.
