Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 277 words
A nestable flower pot, comprising: said pot being molded from expanded polystyrene to form a unitary pot comprising sidewalls having a wholly frusto-conical shape and a flat bottom wall, for containing a plant with media; said botton wall having a plurality of circular holes and a pair of parallel slots positioned on opposite sides of said plurality of holes, each of said slots extending through said bottom wall for receiving one end of a capillary cloth passed therethrough such that the cloth extends between said slots and across said plurality of holes, said slots having a length relative to said plurality of holes such that said holes are bound between said slots and extend the entire length across the bottom of said flower pot; a base having a plurality of integral legs projecting downwardly from said bottom wall for supporting said bottom wall above the surface on which said base rests, and a plurality of openings extending radially through said base between each adjacent one of said legs for permitting water and air to circulate beneath said bottom wall to provide ventilation of the plant media through said holes in said bottom wall; a plurality of reinforcing ribs integrally formed with said pot projecting radially outwardly and extending longitudinally along said sidewalls in alignment with said legs such that each said leg is reinforced by at least one of said ribs, said ribs each extending from the top to the bottom of said flower pot; and a plurality of integral stacking ribs projecting radially inwardly from said side walls and terminating in a common plane for supporting the base of a like pot nested within said pot.
