Abstract
A roll film dispenser is disclosed which utilizes a switch-retractable serrated blade to cut film being dispensed. In one embodiment of the invention, the roll film dispenser contains a roll of film which is arranged so that the end of the roll exits the dispenser through a slot at the top. Severance of the film is accomplished by tearing the sheet over the serrated blade. When not in use, the serrated blade may be manually retracted. Optionally, an acrylic sheet may be interposed between the slot and the blade to aid in stabilizing PVC-type films prior to cutting. A conforming weight is provided at the lower rear of the dispenser to resist rollover.
