Abstract
A thin-walled cup including wall portions having internal and external surfaces so shaped that, when the cup is nested with an identical cup in an upright attitude, the said external surfaces of the upper cup cooperate with the said internal surfaces of the lower cup, so as to resist separation of the cups, provide a seal between the cups, and provide for cushioned relative movement of the cups towards each other, with a limit to such movement.
