US Patent 8701914 Two-part recyclable cup

A paper cup or shell with a thin removable liner that is not laminated to the cup or shell such that the liner may be easily disengaged, removed, or separated from the cup or shell prior to disposal or the recycling process. The thin removable or detachable liner is preferably made from aluminum, aluminum alloy, or aluminum foil, as opposed to other recyclable materials. Aluminum is the preferred material for the liner due to the fact that aluminum is infinitely recyclable and can be used over and over again to make recycled aluminum products or recycled detachable cup liners.
