Abstract

A packaging system suitable for distributing and dispensing disposable cups and lids includes a protective sleeve as well as a polymer envelope. The protective sleeve is configured to receive a nested stack of lids at its upper portion as well as a nested stack of cups at its lower portion. In one preferred embodiment a separator disk separates the two nested stacks and the cups are paperboard cups adapted for hot beverages by having foamed insulation on their outer surface. In another preferred embodiment, a pressure-sensitive adhesive mount is provided which can be removed from a mounting surface without leaving substantial pressure-sensitive adhesive residue on the surface.
