ABSTRACT:
A roll paper cover and process for making the same. The roll paper cover includes a flexible plastic cover for the roll of paper towel and a longitudinal dispensing opening therein for dispensing sheets of paper. The paper roll cover may comprise a thin, partially clear plastic sheet, heat sealed around a paper roll and having a longitudinal series of perforations therein to be torn open to define a dispensing opening. Circumferential perforation segments may be provided to enlarge the dispensing opening and provide a flap. An alternative embodiment may include elastic means for radially collapsing the cover upon dispensing of the roll. Furthermore, a closure, such as Velcro, may be provided for a flap covering the dispensing opening. Various processes for making the claimed device may be employed, including heat sealing plastic around the top and bottom ends of the roll of paper, and scoring a longitudinal series of perforations therein.
