Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
199 words
A tray for use in stacked relationship and adapted for the growth of mushrooms comprising: four upright tubular aluminum legs defining the corners of a rectangle, two opposed aluminum side panels and two opposed aluminum end panels connected to corresponding areas of said legs to define a rectangular enclosure having the legs extending beyond said panels, each of said end panels having a bottom flange which extends inwardly of said container at a right angle to said panel a sufficient distance to provide connection means for bottom members adjacent the ends of said bottom members, a plurality of spaced angular aluminum bottom members, each of which is connected adjacent each end thereof to the bottom flange of said opposed end panels, to provide a rigid discontinuous support for the contents of said tray, the spacing between said angular bottom members providing a multiplicity of slots adapted to expose the base of the contents of the tray to ambient conditions, and nesting means seated in the top and bottom openings of said tubular legs and adapted to nest in slip-resistant relation with corresponding nesting means on the legs of other corresponding trays when said trays are used in stacked relationship.
Claim 2
Dependent Claim
199 words
A tray for use in stacked relationship and adapted for the growth of mushrooms comprising: four upright tubular aluminum legs defining the corners of a rectangle, two opposed aluminum side panels and two opposed aluminum end panels connected to corresponding areas of said legs to define a rectangular enclosure having the legs extending beyond said panels, each of said end panels having a bottom flange which extends inwardly of said container at a right angle to said panel a sufficient distance to provide connection means for bottom members adjacent the ends of said bottom members, a plurality of spaced angular aluminum bottom members, each of which is connected adjacent each end thereof to the bottom flange of said opposed end panels, to provide a rigid discontinuous support for the contents of said tray, the spacing between said angular bottom members providing a multiplicity of slots adapted to expose the base of the contents of the tray to ambient conditions, and nesting means seated in the top and bottom openings of said tubular legs and adapted to nest in slip-resistant relation with corresponding nesting means on the legs of other corresponding trays when said trays are used in stacked relationship.
Claim 3
Dependent Claim

Claim 4
Dependent Claim
35 words
A tray according to claim 1 in which said side panels and said end panels are connected to said legs adjacent the tops thereof, whereby said legs extend below the bottom members of the tray.
Claim 5
Dependent Claim
15 words
A tray according to claim 1 in which said nesting means comprise mating multi-pyramidal surfaces.
Claim 6
Dependent Claim
