Abstract
A drinking cup has sandwiched between an inner paper liner and an outer paper shell a ridge structure which has its ridges running peripherally, i.e. perpendicular to the axis, e.g. in the form of corrugations, a mesh or a cell network and can be partially filled with a phase-transition material to maintain a maximum temperature at the exterior of the shell for a given hot temperature of the liquid within the cup.
