Abstract

A bakery basket is molded of synthetic resin, plastic, and is provided with three levels: a fully nested level, and two different upper stacked levels, one being formed by rigid stacking surfaces engaging when the trays are rotated 180 degrees from their nesting position and the other stacking level being provided by flipping bails for either rotated position of the trays. A particular bail hinge construction is disclosed and bail position retainers in the middle of the bail to hold one of its positions, for example, the nesting position.
