Abstract
Abstract A cellular tray for receiving a plurality of rows of flower plants or the like for cultivating or displaying them comprises alternate frustoconical cavities for receiving said plants in pots or the like and frustoconical holes constituting respective ventilating shafts for aerating the undersides of the leaves of the plants received therein, each hole being disposed at the center of a circle, along which the axes of four pot-receiving cavities are disposed with a 90* spacing, each cavity having its minor base opening at the bottom face of the tray and its major base opening at the top face of the tray. The holes have opposite tapers and comprise at their upper end a collar projecting from the top face of the tray. This tray further comprises a projecting marginal portion. Grooves formed in the lateral walls of the cavities facilitate the draining of water through the cavities alone.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
155 words
A tray comprising a generally flat rectangular parallelopipedal solid body defined between a top face, a bottom face and four imperforate lateral faces bounding said body on the four lateral sides therof, said body being formed with a plurality of rows of frustoconical cavities each adapted to receive a potted plant, each of said cavities having a large-diameter base opening substantially at said top face and a small-diameter base opening substantially at said bottom face, said tray being further formed with a multiplicity of throughgoing frustoconical holes tapering in a direction opposite to the direction of taper of said cavities for ventilating the underside of the leafs of plants in pots received in said cavities, said holes each having a smalldiameter base opening substantially at said top surface and a large-diameter base opening substantially at said bottom surface, said top and bottom surfaces being substantially imperforate except for the openings of said holes and cavities.
Claim 2
Dependent Claim
155 words
A tray comprising a generally flat rectangular parallelopipedal solid body defined between a top face, a bottom face and four imperforate lateral faces bounding said body on the four lateral sides therof, said body being formed with a plurality of rows of frustoconical cavities each adapted to receive a potted plant, each of said cavities having a large-diameter base opening substantially at said top face and a small-diameter base opening substantially at said bottom face, said tray being further formed with a multiplicity of throughgoing frustoconical holes tapering in a direction opposite to the direction of taper of said cavities for ventilating the underside of the leafs of plants in pots received in said cavities, said holes each having a smalldiameter base opening substantially at said top surface and a large-diameter base opening substantially at said bottom surface, said top and bottom surfaces being substantially imperforate except for the openings of said holes and cavities.
Claim 3
Dependent Claim
48 words
The tray defined in claim 1 wherein said holes are provided in rows between the rows of said cavities and each of said holes has an axis lying at a center of a circle along which the axes of four of said cavities are disposed with 90* spacing.
Claim 4
Dependent Claim
41 words
The tray defined in claim 2 wherein said body is provided along its periphery with an upstanding ledge and each of said small-diameter bases of said holes is formed with an annular collar projecting above the large-diameter bases of said cavities.
Claim 5
Dependent Claim
44 words
The tray defined in claim 3 wherein said body is formed at each of said cavities with a plurality of angularly spaced axially extending narrow grooves reaching substantially from the large-diameter bases of said cavities downwardLy to a location above the small-diameter bases thereof.
