A reinforced plastic foam cup including a body which defines an open top end and a closed bottom end, wherein the top end has a greater diameter than the bottom end. The body includes a reinforced tapered side wall that extends from the bottom end to the top end. A substantial portion of the reinforced tapered side wall includes a plastic foam layer, a pressure sensitive adhesive layer and a rigid material layer. Such reinforced plastic foam cup provides an improved tactile feel and enhanced insulation and rigidity properties.
The invention claimed is: 1. A reinforced plastic foam cup comprising: a plastic foam conical body which has: an open top end including an outwardly rolled lip, a closed bottom end having a diameter less than the top end, and a tapered wall extending from the bottom end to the top end, said tapered wall having an outer surface and an inner surface; and a flat reinforcing member affixed around the outer surface of the tapered wall in an overlapping manner, said reinforcing member including a body having (i) a rigid material layer having an inner surface...
