Abstract: A combination disposable cup insulator/stabilizer and the process and method for making the same comprising the steps of selecting a first disposable cup demonstrating a frustoconical configuration, separating the upper portion of the first cup from its lower portion by slicing the cup about its mid-section, discarding the lower portion, and retaining the upper portion for use as a combination insulator/stabilizer. When used a cup liner/insulator, the upper portion of the first disposable cup is slid from below over the outside of a second disposable cup identical in size and shape to the first disposable cup. When used as a cup stabilizer, the upper portion of the first cup is inverted to receive the base of a second disposable cup identical in size and shape to the first disposable cup. The same combination insulator/stabilizer can be fabricated by modifying existing manufacturing facilities to produce top cup portions only.
