Abstract
Abstract A stackable, nestable shipping tray for fruit. The tray is formed from a single plastic sheet and has a plurality of pockets interspersed by posts which engage the underside of the pockets to support the trays when they are in stacked relation. Grooves and channels in the posts, holes in the pockets and recesses in a border flange around the sheets promote airflow around the fruit as well as drainage of moisture. The configuration of the trays and their relation to the container in which they are disposed for shipping provides maximum protection to the fruit.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
188 words
A stackable, nestable shipping tray for fruit comprising, a single molded sheet having a generally planar peripheral border, a plurality of fruit-receiving pockets formed in said sheets, the upper edges of said pockets lying in a plane, a plurality of posts formed in said sheet and located adjacent said pockets, said posts projecting a uniform height above said plane a distance substantially greater than the depth of said pockets, said pockets having a depth which is less than one-third the overall height of a tray, said posts presenting generally vertical surfaces, said vertical surfaces having vertical grooves extending into said pockets, said pockets having holes in the bottom thereof, at least a portion of said pockets having an undersurface which is adapted to rest upon a respective post when a plurality of like trays, oppositely oriented, are in stacked relation, said posts having upper surfaces which receive the undersurfaces of said pockets, said surfaces having grooves therein to facilitate air and liquid flow, said posts, grooves and holes permitting air and liquid flow around the fruit between the top and bottom of a stacked group of filled trays.
Claim 2
Dependent Claim
188 words
A stackable, nestable shipping tray for fruit comprising, a single molded sheet having a generally planar peripheral border, a plurality of fruit-receiving pockets formed in said sheets, the upper edges of said pockets lying in a plane, a plurality of posts formed in said sheet and located adjacent said pockets, said posts projecting a uniform height above said plane a distance substantially greater than the depth of said pockets, said pockets having a depth which is less than one-third the overall height of a tray, said posts presenting generally vertical surfaces, said vertical surfaces having vertical grooves extending into said pockets, said pockets having holes in the bottom thereof, at least a portion of said pockets having an undersurface which is adapted to rest upon a respective post when a plurality of like trays, oppositely oriented, are in stacked relation, said posts having upper surfaces which receive the undersurfaces of said pockets, said surfaces having grooves therein to facilitate air and liquid flow, said posts, grooves and holes permitting air and liquid flow around the fruit between the top and bottom of a stacked group of filled trays.
Claim 3
Dependent Claim
60 words
A shipping tray as in claim 1 in which the upper surfaces of at least most of said posts are concave to receive the convex undersurface of each pocket thereby limiting side-to-side shifting of one tray with respect to the other when said trays are in stacked relation, and to reduce the overall height of a stacked group of trays.
Claim 4
Dependent Claim
39 words
A shipping tray as in claim 1 in which a portion of said pockets is located adjacent the periphery of said tray with an edge portion of each said peripheral pocket being immediately adjacent the edge of said tray.
Claim 5
Dependent Claim
161 words
A stackable, nestable shipping tray comprising, a single sheet of plastic, a plurality of shallow pockets formed in said sheet, the upper edges of said pockets lying in a plane, a plurality of posts formed in said sheet and projecting a uniform height above said plane, said pockets having a depth which is less than one-third the overall height of said tray, said posts having upper surfaces engageable with undersurfaces of said pockets to support said pockets when a plurality of like trays are oppositely oriented and are in stacked relation, said sheet having a thin generally planar border flange surrounding said pockets and posts, the corners of said flange being beveled and said flange adjacent said posts being recessed to provide improved air circulation throughout a group of stacked trays in a container, said posts having vertical channels to improve airflow and to provide strength to said posts, at least some of said channels being aligned with said flange recesses.
Claim 6
Dependent Claim
161 words
