  • Patent number: 4762042
    Abstract: A refillable dispenser for web materials has a housing 1 and a snap-fitted cover 2. A slidable cutter 3 rides in a slit 25 of cover 2. A vertical cutting support surface 11 is formed as an integral extension of a horizontal roll support plate 9. Baseplates 9 may also be integrally formed with back wall 8 of housing 1. The junction of plate 9 and cutting surface 11 define with the adjacent edge of cover 2 a dispensing slot 14, so replacement of rolls 17 is facilitated and threading of web material is simplified. A cooperating lip 18 and recess 19 on surface 11 facilitate grasping the end of the web, and a labyrinthine web path 20 defined by ribs 15, 16 prevents retraction of web material, particularly clingly plastic wrap, back onto the roll after cutting. A leaf spring 29 inside cover 2 urges a disk-shaped blade 23 into a slot 24 of surface 11 while a housing surrounding the blade protects the user.
