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.

A nestable and stackable container, comprising a unitary, one piece, container body of molded synthetic resin material having a bottom wall and two pairs of opposed side walls integrally joined together and integrally extending upwardly from the periphery of said bottom wall; said side walls being shaped and extending upwardly and outwardly from said bottom wall to permit said container body to be nested within a like container body and the latter to be nested therein when disposed in vertical aligned relationship therewith; a pair of bails, each being a unitary, one piece, construction of molded synthetic resin; hinge means unitary in one piece only with each of said bails and one pair of said opposed sidewalls for pivotally connecting said bails to said one pair of sidewalls, respectively, for movement about respective parallel horizontal axes that are parallel to said bottom and the longitudinal extent of said one pair of sidewalls to provide for pivotal movement of said bails relative to said container body between a stacking position wherein each bail extends generally horizontally inwardly from its associated pivot axis into the adjacent interior of the container body toward the opposed sidewall of said one pair of sidewalls to provide respective upwardly facing support stack surfaces, and a nesting position wherein each bail is disposed outwardly of the adjacent interior of the associated sidewall to permit said nesting of two like container bodies; bail support surfaces on said one pair of opposed sidewalls spaced from the adjacent corresponding pivot axes and engaging the respective bails in their stacking position at contact points spaced radially from said respective pivot axis to resist inward turning movements on said bails; said bail structures, when in said stacking position, having their support stack surfaces simultaneously engaging a like container stacked thereon in vertical aligned relationship above said container body; said hinge means comprising a plurality of longitudinally spaced, upwardly extending, first pivot portions of molded synthetic resin integral, in one piece, with the upper edge of each of said one pair of sidewalls, a plurality of longitudinally spaced second pivot portions of molded synthetic resin integral, in one piece, with and along a longitudinal edge of each of said bails that are of a spacing and of a longitudinal length so as to inter-engage longitudinally with said first pivot portions of the associated sidewall of said one pair of sidewalls, a plurality of pivot pins coaxial with a respective pivot axis extending from at least one of said first pivot portions and said second pivot portions, and said pivot pins being constructed of molded synthetic resin integral, in one piece, with said one pivot portions, and the other of said first and second pivot portions having longitudinally extending bearing apertures coaxial with said respective pivot axes and of a diameter substantially equal to the diameter of respective pivot pins; said second pivot portions integrally and in one piece including means providing assembly of said pivot pins within respective apertures; said assembly means including slots opening radially from said bearing apertures to permit only radial assembly of said pins through said slots into said bearing apertures only when said bails are in an assembly position that is pivotally spaced from said pivotal movement of said bails relative to said container body between the stacking position and the nesting position; and said bails and said sidewalls having interengaging stop surfaces positively preventing rotation of said bails through said nesting position to said assembly position.
