Abstract
Abstract A carton is provided for dispensing sheet material from a roll thereof disposed in the carton. The carton has a hood panel and a material tearing member which is preferably mounted on the lower edge of the hood panel. A hood panel engaging portion is provided on the front panel of the carton for releasably holding the hood panel in overlying relationship with the front panel to close the carton. If the carton is used to dispense plastic sheet material, the front panel is provided with one or more openings which allow the end portion of the plastic sheet to be pressed against the roll of plastic sheet through the openings whereby the natural tackiness of the plastic material holds the end portion of the sheet against the outer surface of the front panel of the carton.
