ABSTRACT:
This invention pertains to an upstanding container having a corrugated sidewall. Flutes in the medium of the corrugated sidewall follow preferably equal and opposite alternating lateral divergences from generally longitudinal upstanding axes. Preferred alternating divergences are waves having gradually changing angles of divergence from the respective upstanding axes. Thus, preferred medium is characterized by a pattern of wavy flutes. The pattern of wavy flutes provides improved strength and rigidity imparted by the horizontal components of the waves. Wavelength of the flutes is generally no greater than the height of the container. Wave amplitude is preferably between about 1/20th and about 1/80th of the circumference of the container. Spacing between flutes may be uniform from top to bottom of the container. In some embodiments, spacing between flutes is greater at or adjacent the top of the container than at or adjacent the bottom of the container.
