US Classification:

221213

Abstract:

A dispensing device is disclosed for dispensing nested dished papers. The device has a base for holding a stack of nested dished papers. The dishing of the papers is such that each paper has a bottom wall and a substantially conical side wall. The device includes a paper sticking member mounted on the base adjacent to the stack of nested dished papers. The stack of nested dished papers and the paper sticking member are moved relative to each other so that the conical side wall of the adjacent paper of the stack of nested dished papers is stuck with the paper sticking member. The conical side wall and continued relative movement of the paper sticking member are used for pulling the paper from the stack of nested dished papers and dispensing the same.
