Abstract A self-watering flower pot has a unitary, double-walled construction comprising an outer shell, a potting receptacle therewithin, and a water-receiving chamber in the space between the outer shell and the inner receptacle. An upwardly opening recess is defined in the upper surface of the bottom wall of the outer shell, and the potting receptacle has a depending peripheral wall element which extends about a passageway through a lower portion thereof and is disposed with its lower edge within the recess of the bottom wall. In operation a vacuum is created in the space between the double walls, which is relieved when the soil within the potting receptacle becomes sufficiently dry to permit air to permeate and pass outwardly into the chamber. This effectively meters the water by allowing a small amount to flow as dictated by the dryness of the soil. The elements in the lower portion of the flower pot trap the soil and thereby eliminate the need for a porous plug of the type which is normally used for that purpose at such a water/soil interface.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
46 words
The flower pot of claim 1 wherein said upstanding portion is provided by a rib in said bottom wall portion adjacent the center thereof and wherein said bottom wall portion of said potting receptable is configured to provide a depending rib forming said depending wall element.
Claim 2
Dependent Claim
40 words
The flower pot of claim 1 wherein said bottom wall portion of said inner shell element is configured to provide a plurality of doWnwardly opening channels sloping upwardly and outwardly towards said sidewall thereof from adjacent said depending wall element.
Claim 3
Dependent Claim
41 words
The flower pot of claim 1 wherein said sidewalls of both said shell elements, said cavity in said outer shell element and said depending wall element in said inner shell element all are substantially circular in cross section and are concentric.
Claim 4
Dependent Claim
59 words
The flower pot of claim 1 wherein the bottom wall portion of said outer shell element extending toward said sidewall thereof from said cavity therein is spaced a short distance from the adjacent bottom wall portion of said inner shell element to define therebetween a narrow peripheral flow passage from said cavity to said chamber between said shell elements.
Claim 5
Dependent Claim
59 words
The flower pot of claim 5 wherein said bottom wall portion of said outer shell element is a thin wall having an upstanding rib spaced inwardly from said sidewall thereof providing said upstanding portion defining said cavity, said rib being continuous and of inverted, generally U-shaped cross section and projecting above the lowest plane of said bottom wall portion.
Claim 6
Dependent Claim
67 words
The flower pot of claim 1 wherein there is included interconnecting means securing said bottom wall portion of said outer shell element to said bottom wall portion of said inner shell element, thereby rigidifying said flower pot and tending to maintain the spacing of said flow path between said depending wall element of said inner shell element and said bottom wall portion of said outer shell element.
Claim 7
Dependent Claim
26 words
The flower pot of claim 7 wherein said securing means comprises a plurality of spaced ribs extending between said bottom wall portions of said shell elements.
Claim 8
Dependent Claim
17 words
