The present invention describes a corrugated cardboard container having improved load bearing features. Typically corrugated cardboard containers are made of a rectangular base and upstanding side walls projecting from the base to define a box, which may be flap closable. Such containers are well known and used for shipping and/or storing goods, at which time they are stacked one on top of each other. In some cases, the stack may be overloaded and one or more containers may buckle, which may result in reduced load-bearing capability of the stack and may damage the goods within. In order to improve the load-bearing capability of the container, at least one sidewall includes a feature extending across the 'would be' line of creasing of the sidewall to isolate the vertical sidewall edge adjacent said feature from failure.
