Abstract

A disposable biodegradable insulated container includes a smooth walled frustoconical inner cup received within a frustoconical wrap. A series of angularly spaced apart fluted indentations formed in the outer surface of the wrap extend longitudinally of the wrap and terminate in spaced relation to the upper and lower edges of the wrap. The indentations define corresponding angularly spaced apart and inwardly directed ribs on the inner surface of the wrap which engage the sidewall and maintain portions of the wrap intermediate the ribs in spaced relation to the sidewall. The upper and lower marginal portions of the wrap are adhered to the sidewall. The thickness of the wrap is greater than the distance between the inner surface of the wrap and the outer surface of the sidewall measured from the central axis of the container in a radial direction and between the ribs. A method for making the container is also disclosed.
