초록

A base cup for a container includes reinforcing ribs which provide both the requisite strength and rigidity and a reduction in weight. The ribs are preferably disposed on the inner surface of the base cup for cosmetic reasons and may be arranged in various generally symmetrical radial and circumferential patterns. Ribbed base cups fabricated according to the instant invention exhibit significant weight and material reductions over prior art designs while still providing necessary stability and support to the associated container.
