<p>A dispenser (10) is used for dispensing plastic film from a roll (78). The dispenser has a housing (12) that may be mounted under a shelf or cupboard or on a wall. The housing consists of a cover unit (16) that is installed in the place of use and a releasable base unit (14) that fits into the bottom of the cover unit and is held in place with resiliently biased locking tabs (56). The base unit carries the roll of film (78), so that the roll is readily installed on the base unit when separated from the cover. The loaded base unit is easily lifted into place. The film (80) is dispensed through a dispensing slot (46) at the back of the base unit. Lengths of film are severed using a cutter (30) at the front of the base unit. A replacement cutter (90) can be clipped onto the original cutter (30). The length of film between the dispensing opening and the cutter is prevented from clinging to the underside of the base unit by using a discontinuous, rough surface (48) on the under side of the base plate (44). The non-planar aspect of the surface is preferably provided by a series of ribs (50) and a sandblasted surface texture to provide the desired non-planar, roughened surface.</p> |
