Abstract
Abstract A multi-tray basket that includes a plurality of trays, and a one-piece basket frame comprised of opposed side walls connected together by a floor. The trays each include downwardly depending lips adapted to seat on shelf rails molded integral with the basket's side walls. Each tray's lips cooperate with front and rear stops on each shelf rail to prevent forward/rearward motion of the tray on the rail once the tray is seated thereon. Each tray's lips also cooperate with lateral stops on the upper shelf rails to prevent lateral spreading of the side walls where the basket is loaded. Each side wall includes a stacking rib along the top edge thereof, and includes a stacking rail along the bottom edge thereof. A first basket's stacking ribs are adapted to interfit with a second basket's stacking rails so that successive baskets may be stacked and retained one on top the other by the interfit of the stacking ribs and the stacking rails.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
233 words
A multi-tray basket comprising a molded basket frame having a floor and two opposing side walls, said frame being fabricated of a one-piece configuration, at least one unitary molded tray adapted to be located between said opposing side walls at a vertical position elevated above said floor, said tray including a downwardly depending rib on each of the two opposing side edges thereof, at least one shelf rail formed integral with each of said basket's two side walls, said tray's ribs being adapted to sit on said shelf rails for locating said tray at said elevated vertical position, a front stop on at least one of said shelf rails, and a rear stop on at least one of said shelf rails, to prevent forward/rearward motion of said tray on said rails once said tray is seated thereon, stacking structure molded integral with the top and bottom edges of each side wall for permitting an upper multi-tray basket to be stacked on top a lower multi-tray basket, said stacking structure including a stacking rib on the top edge of each side wall, and a stacking rail along the bottom edge of each side wall, said stacking ribs and rails being adapted to interfit one with the other to prevent forward/rearward motion of said upper basket relative to said lower basket and to prevent lateral motion of said upper basket relative to said lower basket.
Claim 2
Dependent Claim
233 words
A multi-tray basket comprising a molded basket frame having a floor and two opposing side walls, said frame being fabricated of a one-piece configuration, at least one unitary molded tray adapted to be located between said opposing side walls at a vertical position elevated above said floor, said tray including a downwardly depending rib on each of the two opposing side edges thereof, at least one shelf rail formed integral with each of said basket's two side walls, said tray's ribs being adapted to sit on said shelf rails for locating said tray at said elevated vertical position, a front stop on at least one of said shelf rails, and a rear stop on at least one of said shelf rails, to prevent forward/rearward motion of said tray on said rails once said tray is seated thereon, stacking structure molded integral with the top and bottom edges of each side wall for permitting an upper multi-tray basket to be stacked on top a lower multi-tray basket, said stacking structure including a stacking rib on the top edge of each side wall, and a stacking rail along the bottom edge of each side wall, said stacking ribs and rails being adapted to interfit one with the other to prevent forward/rearward motion of said upper basket relative to said lower basket and to prevent lateral motion of said upper basket relative to said lower basket.
Claim 3
Dependent Claim
51 words
A multi-tray basket as set forth in claim 1 including at least two pairs of said shelf rails, each pair of shelf rails including said front and rear stops and each pair of shelf rails including said lateral stops, said tray being located on one of said pairs of shelf rails.
Claim 4
Dependent Claim
59 words
A multi-tray basket as set forth in claim 1, said basket including at least two pairs of said shelf rails, one pair of said shelf rails being disposed adjacent the top edge of said side walls and the other pair of said shelf rails being disposed adjacent said floor, that pair adjacent said floor not having lateral stops thereon.
Claim 5
Dependent Claim
54 words
A multi-tray basket as set forth in claim 1, said basket including air port structure in the side walls and in said floor of said basket frame, and air port structure in the floor of said tray, all of said air port structures cooperating to permit horizontal and vertical ventilation through said multi-tray basket.
Claim 6
Dependent Claim
52 words
A multi-tray basket as set forth in claim 2, said basket including a backstop rail extending from adjacent the top edge to adjacent the bottom edge of each side wall, each backstop rail defining said rear stop for said shelf rails on that side wall to which said backstop rail is mounted.
Claim 7
Dependent Claim
64 words
A multi-tray basket as set forth in claim 2, said basket including transverse strength ribs formed integral with said basket frame at the front edge and at the rear edge thereof, said transverse strength ribs extending upwardly from said floor to adjacent a pair of lowermost shelf rails, said front transverse strength rib defining said front stop for each of said lowermost shelf rails.
Claim 8
Dependent Claim
28 words
A multi-tray basket as set forth in claim 1, said basket including a plurality of horizontal and vertical strength ribs on the exterior face of each side wall.
