Filed:
Sep 11, 1995
Appl. No.:
8/526685
Inventors:

John W. Thomas - Pittsburgh PA
Steven D. Goldenbogen - Pittsburgh PA
David L. Volk - Clairton PA
International Classification:
B65H 108
US Classification:
221232
Abstract:
A gum dispenser includes a substantially rectangular, box shaped container having a platform therein. The platform is disposed substantially parallel to a first wall and a second wall of the container. When sticks of gum are positioned between the platform and the second wall of the container, a spring urges the platform against the sticks of gum, and a leading stick of gum is urged against the second wall of the container. The second wall of the container includes a track, with an operator slidably engaged therein. When a user slides the operator toward a slot in the lid of the dispenser, a seat of the operator engages a short edge of the leading stick of gum and pushes the gum partially through the slot, thereby dispensing the gum. The container further includes a base with a notch therein for limiting movement of the operator in a direction away from the lid, so that the operator remains engaged within the track. The dispenser is preferably constructed of plastic or other suitable, rigid, non-permeable material.
