US Patent 7086555 Container

A wall structure for a container includes at least one band member which extends at least partially across the length of the wall structure proximate an upper surface of the wall structure and oriented substantially parallel thereto. The band member has a wave-like cross-section with a plurality of first peaks, adjacent and opposing second peaks, and inclined members extending between the plurality of first and second peaks. The plurality of first peaks of the wave defines a first surface of the wall structure, and the opposing second peaks of the wave defines a second surface of the wall structure.
