ABSTRACT:
An open top container having at least one side wall constructed of vertically disposed panels having horizontally extending corrugations or ribs lending beam and column strength to the side wall panels. The panels of that side wall can have an interconnecting slip joint permitting limited horizontal movement between the panels. The top rail of at least that side wall can have inner and outer sleeved sections permitting limited longitudinal movement of the top rail to relieve the unit compressive forces on the top rail imposed by a load in the container. Preferably the slip joint is generally midway of the side wall and closely adjacent the top rail sleeved sections. Also, both side walls of a rectangular container for maximum advantage should include the horizontal corrugations, and slip joint and the top rail sleeved sections.
