A light weight low depth nestable tray for containers comprising an open lattice floor structure and a wall structure that is contoured to reduce the amount of material used for the tray. The wall structure comprises a plurality of columns interconnecting the floor to a band that is generally spaced above the floor and extends around the periphery. The band is contoured at a number of points along the periphery of the tray to reduce the number of columns as compared to the prior art trays which generally have columns at each of the corners and along the end walls and side walls. The reduction in the number of columns reduces the weight of the tray and therefore is more economical. The contour is V-shaped and the band actually connects directly to the floor at those points. The contoured wall structure provides a lighter tray that can be stacked, nested and handled in the same way as prior trays and while maintaining the structural integrity of the bulkier, heavier trays.
