Abstract
A tray having prestressed sections including a domed shaped bottom and a merchandising window. The window includes a surface parallel to the dome shaped bottom. When the tray is subjected to a load, the dome and the surface of the merchandising window become substantially planar. The front of the tray also includes vertically extending corners that are angled inwardly toward one another from an outer top end to an inner lower end when the tray is empty. When the tray is loaded, the corners deflect toward a vertically extending parallel relationship with respect to one another. The corners adjacent the rear of the tray are fixed relative to one another. A stackable dolly supports stackable trays for allowing movement of stacked trays from one location to another on casters or wheels connected to the stackable dolly. The dollys are stackable with respect to one another when not in use. Each dolly can have recessed notches to receive the casters or wheels of an adjacent upper stacked dolly. The recessed notches can include a ramp extending in a direction aligned with one another and/or can be positioned to extend in a direction at offset angular orientations with respect to one another for improved stacking stability of the dollys.
