ABSTRACT:
A stacking and nesting container, particularly a bakery tray, is provided with bails on two opposed sidewall top edges that are pivotable between a nesting position when the trays may be nested within each other and a stacking position wherein a like tray may have its bottom supported by the bails of a lower tray, and the entire structure is molded of synthetic resin material, without metal parts or separate hinge components. The hinge for the bails is formed by pins molded into the bails and fit within self locking bearing aperature of the sidewalls.
