Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
302 words
A one piece molded tray adapted to be stacked with like trays comprising, a generally rectangular body having sides, ends and a bottom defining an enclosure, said sides and ends having planar top surfaces to the bottom surface, said top and bottom lying in parallel planes, longitudinally and laterally spaced feet having flat bottom surfaces integrally attached to said bottom at the ends thereof and extending downwardly from said bottom providing a space below said tray bottom and between said feet at the sides and ends to receive hands, said feet having flat planar bottom surfaces, spaced downwardly extending ribs on said bottom surfaces of said feet and spaced upwardly extending ribs on said top surface of said ends adapted to receive said spaced ribs on the bottom of the feet of a like tray thereby restraining said trays from lateral shifting, said ribs being spaced from one another sufficiently to allow intermeshing ribs of another like tray, said sides, ends, and bottom of said tray being formed as said smooth planar surfaces, except for said upwardly extending ribs thereby preventing the retaining of foreign matter, said ribs on said bottom surface of said feet and said ribs on said top surface of said sides being inclined toward longitudinal center of said tray and outwardly to prevent lateral, longitudinal and angular misalignment without compromising stacking ability, wherein the side edges of said ribs are disposed at an acute angle to the side edges of said tray, said angle being of a magnitude that a line parallel to a side edge of said tray, passing through a side edge of one said rib adjacent an end thereof will pass through a side edge of the rib adjacent said first mentioned rib at the end of said second mentioned rib adjacent an end thereof.
Claim 2
Dependent Claim
302 words
A one piece molded tray adapted to be stacked with like trays comprising, a generally rectangular body having sides, ends and a bottom defining an enclosure, said sides and ends having planar top surfaces to the bottom surface, said top and bottom lying in parallel planes, longitudinally and laterally spaced feet having flat bottom surfaces integrally attached to said bottom at the ends thereof and extending downwardly from said bottom providing a space below said tray bottom and between said feet at the sides and ends to receive hands, said feet having flat planar bottom surfaces, spaced downwardly extending ribs on said bottom surfaces of said feet and spaced upwardly extending ribs on said top surface of said ends adapted to receive said spaced ribs on the bottom of the feet of a like tray thereby restraining said trays from lateral shifting, said ribs being spaced from one another sufficiently to allow intermeshing ribs of another like tray, said sides, ends, and bottom of said tray being formed as said smooth planar surfaces, except for said upwardly extending ribs thereby preventing the retaining of foreign matter, said ribs on said bottom surface of said feet and said ribs on said top surface of said sides being inclined toward longitudinal center of said tray and outwardly to prevent lateral, longitudinal and angular misalignment without compromising stacking ability, wherein the side edges of said ribs are disposed at an acute angle to the side edges of said tray, said angle being of a magnitude that a line parallel to a side edge of said tray, passing through a side edge of one said rib adjacent an end thereof will pass through a side edge of the rib adjacent said first mentioned rib at the end of said second mentioned rib adjacent an end thereof.
Claim 3
Dependent Claim
55 words
The tray recited in claim 1 wherein laterally spaced downwardly extending lugs attached to said bottom adjacent each end of said tray between said spaced feet, said lugs being disposed on either side of the center of each end of said tray providing a space for receiving the hand of a mechanical tray handling device.
Claim 4
Dependent Claim
38 words
The tray recited in claim 2 wherein said top flat surfaces of said tray engage a second part of said device, when said bottom part of said tray is engaged by said first mentioned part of said hand.
Claim 5
Dependent Claim
47 words
The tray recited in claim 1 wherein the spacing between said ribs is less than 2L SIN H + L (COS H - SIN H COS H) when L is the rib length and H is the angle of the rib to a side of the tray.
