Abstract
A container sidewall, such as for a cup or the like, made of a thermoplastic material is disclosed. The container utilizing the present invention is preferably designed having a closed bottom wall at one end, an open top at the opposite end, and the present sidewall extending between the bottom wall and the open top to define a height. The sidewall has a top portion adjacent the open top of the container, a first set of annular ribs disposed adjacent the top portion, a second set of annular ribs, a middle portion disposed between the first set and second set of annular ribs, and a bottom portion disposed adjacent the closed bottom wall of the container. The double band of ribs provide an increase in the strength-to-weight ratio of the container over single band prior art designs.
