Abstract

Apparatus and methods relate to containers having a sidewall portion with at least one generally vertical corrugation therein. The containers can be of a variety of shapes, sizes, cross-sections, and materials. The corrugation improves the container sidewall strength and resistance to buckling under compressive loads such as stacking of multiple containers.

Claims

Claims:
1. A method of fabricating a container, including the steps of:
a) Providing a plastic injection mold having at least one corrugation pattern in a sidewall portion thereof; and b) Injecting plastic into said mold to form a container.
