ABSTRACT:
A one-piece carton blank is erected into a carton containing a sheet of material rolled on a spool, the carton having a liftable top panel which is connected to a hood panel. The hood panel has a cutting edge, for example, a metal serrated strip protruding from its free edge, to tear the selected length of the sheet material. When the carton is closed the hood panel lies against the front panel of the carton. The carton is opened by the user inserting a finger through one, or preferably two, orifices in the hood panel and pushing against the front panel to break adhered areas and thereby free the hood from the front panel. The hood may have one or more liftable strips formed by parallel breakable score lines, the strips terminating at the orifice.
