Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
133 words
An insert tray for use with a plant container, the tray including a liquid-filling tube and a plate-shaped surface for partitioning said plant container into a lower liquid space and an upper plant cultivating space, said tray including a plurality of hollow ribs for receiving absorbent material, said ribs extending downwardly from said plate-shaped surface and having openings at the lower ends thereof, the improvement including fitting means extending downwardly from said surface of said tray, said fitting means having at least one passage opening and being adapted to removably receive said liquid-filling tube, said ribs formed with longitudinal walls and lower end walls tapering from a larger size at said plate-shaped surface end towards a smaller size at said lower end walls for the easy stacking of a plurality of insert trays.
