<p>A container sidewall (13), 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 (11) at one end, an open top (12) at the opposite end, and the present sidewall (13) extending between the bottom wall and the open top to define a height. The sidewall has a top portion (14) adjacent the open top of the container, a first set of annular ribs (15) disposed adjacent the top portion, a second set of annular ribs (16), a middle portion (17) disposed between the first set and second set of annular ribs, and a bottom portion (18) 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.</p> |
