ABSTRACT:
Apparatus for dispensing and selectively cutting lengths of plastic film from a roll. A box-shaped container has side, front, rear, and bottom walls, and a cover hinged adjacent the rear wall. The cover affords access to the container, so that a packaged roll of film may be placed inside with its axis extending between and perpendicular to the side walls. The container has side spacers that normally receive a 4-inch width roll package, and a narrower, 2-inch width roll package may be received for which there are provided extensions for the spacers. The spacers slightly compress the package to provide drag on the roll as it becomes lighter. Disposition of the roll package is such that film may be removed from the upper region of the roll, through a slotted opening between the front wall and the adjacent free edge of the closed cover. A pivotal feeder for the film includes a flexible and resilient arm mounted on the bottom wall and biased toward the roll, and a flat top portion engaging the lower side of the film. An opening in the cover is in registry with the flat top portion of the feeder, so that, using the finger to press the film down on the flat top portion, the film and feeder may be moved forward in unison to urge the film through the slot. Release of the film and the feeder permits the latter to spring back to retracted position. The desired length of film may then be pulled out and cut from the roll by a provided cutting blade.
