  • Patent number: 5344022
    Abstract: A stackable, nestable, multi-level tray or basket useful for storing and transporting baked goods is provided which includes a floor and a pair of upstanding side walls configured for stacking identical trays as well as allowing the stacking of a tray with smaller, overall dimensions. The structure enables identical trays to slide on to each other in stacked or nested configurations. A multi-level tray includes sidewalls with a plurality of upright stacking posts extending from the floor to a vertical strip of material. Each stacking post flares out at its top end to a cantilevered, extending flat portion. Trays of smaller overall dimensions than the disclosed tray can be advantageously stacked on these extending flat portions.

  • Patent number: 5287966
    Abstract: A slide-on multi-level basket useful for storing and transporting baked goods is provided which includes a floor and a pair of upstanding side walls configured for stacking identical baskets at three different levels and presenting structure enabling other, identical baskets to slide thereon into stacked or nested orientations. A multi-level basket hereof includes a slideway or rail extending along each of the side walls, the side walls being divided into inner and outer panels. Each basket includes a thin web and a wide web spaced apart and respectively proximate a front end wall and a rear end wall. The thick and thin webs are complimentarily configured with a relieved portion and a slot in each of the side walls whereby the webs can slide along the rail of a next lower, identical basket enabling the upper basket to drop into either a nested or stacked relationship according to the relative orientation of the two baskets, when superposed over the next lower, identical basket.
