Abstract
A disposable combination (10) of an expanded foam cup (12) and an expanded base (14) is disclosed for preventing tipping of the cup and spilling of its contents. The disposable cup (12) has a frusoconical side wall (16) with an upper portion (18) having an open upper end (20) and with a lower end (24) closed by a round bottom (28). The base (14) has a frustoconical shape that coverages in an upward direction in its use position and has the same size and shape as the upper portion (18) of the cup side wall (16) so as to be stackable prior to use. Frustoconical base (14) has a lower end (30) on which the base rests in its use position and has an upper open end (34) that receives the cup during use. Between the upper and lower ends, the frustoconical base (14) has a height according to a prescribed equation that positions the cup bottom (28) and the lower base end (30 ) in a coplanar relationship to provide the support that prevents the cup from tipping during use.
