Abstract
A tape dispenser system includes a monolithic plastic injection molded frame with an integral anti-reverse rotation pawl. To help prevent the free end of a roll of tape from accidentally retracting, falling back, and frustratingly bonding onto the coiled portion of the tape, the pawl engages the inner diameter of a cardboard spool that holds the roll of tape. Strategically located mold parting lines and certain air gaps allow injection molding of a dispenser frame that has two spool-supporting sidewalls plus the integral pawl.
