Abstract
Abstract A self-watering flowerpot has two chambers: an upper one for accommodating soil and a plant and a lower one for accommodating water. The upper chamber has a downwardly protruding tubular neck and threading around a lower outside periphery thereof. The lower chamber has an upwardly protruding tubular drain and threading around an upper inside periphery thereof. A tubular conduit element made of porous material is positioned between an outside periphery of the drain and inside periphery of the neck when the upper and lower chambers are threaded together. The two chambers are rotatable relative to each other so as to control the flow of water from the lower chamber to the upper chamber via the conduit element. An inlet pipe allows water to be filled into the lower chamber.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
131 words
A device for supporting flora comprising a terra chamber for accommodating soil and flora, an aqua chamber for accommodating a supply of water, engaging means for engaging said terra chamber to said aqua chamber, and conducting means for conducting water from said aqua chamber to said terra chamber; said conducting means comprising an inner pipe protruding downward from a bottom of said terra chamber, an outer pipe protruding upward from a bottom surface of said aqua chamber, and absorbing means for absorbing water; said inner pipe being receivable within said outer pipe; said absorbing means being positionable between said outer pipe and said inner pipe and extending from said aqua chamber into said terra chamber; said engaging means being adjustable, so that said terra chamber is positionable on said aqua chamber.
Claim 2
Independent Claim
131 words
A device for supporting flora comprising a terra chamber for accommodating soil and flora, an aqua chamber for accommodating a supply of water, engaging means for engaging said terra chamber to said aqua chamber, and conducting means for conducting water from said aqua chamber to said terra chamber; said conducting means comprising an inner pipe protruding downward from a bottom of said terra chamber, an outer pipe protruding upward from a bottom surface of said aqua chamber, and absorbing means for absorbing water; said inner pipe being receivable within said outer pipe; said absorbing means being positionable between said outer pipe and said inner pipe and extending from said aqua chamber into said terra chamber; said engaging means being adjustable, so that said terra chamber is positionable on said aqua chamber.
Claim 3
Dependent Claim
125 words
A device for supporting flora as claimed in claim 1, wherein said absorbing means is tubular and comprises an annular flange integrally formed around a bottom periphery thereof, said flange being positioned between a bottom of said outer pipe and said bottom of said aqua chamber; and wherein said engaging means allows said terra chamber to be positionable with respect to said aqua chamber between an "ON" position, where said terra chamber is extended from said aqua chamber, allowing said absorbing means to absorb water; and an "OFF" position, where said terra chamber is tightened on said aqua chamber, thereby pinching said absorbing means between said bottom of said outer pipe and said bottom of said aqua chamber, preventing said absorbing means from absorbing water.
Claim 4
Dependent Claim
44 words
A device for supporting flora as claimed in claim 2, wherein said engaging means allows said terra chamber to be positionable with respect to said aqua chamber gradiently between said "ON" position and said "OFF" position, thereby retarding said absorbing means in absorbing water.
Claim 5
Dependent Claim
38 words
A device for supporting flora as claimed in claim 3, wherein said engaging means comprises threading formed in a lower outside periphery of said terra chamber and threading formed in an upper inside periphery of said aqua chamber.
Claim 6
Dependent Claim
85 words
A device for supporting flora as claimed in claim 1, wherein said absorbing means is tubular and said outer pipe has an inner diameter greater than an outer diameter of said inner pipe; said absorbing means has an outer diameter less than said inner diameter of said outer pipe and an inner diameter greater than said outer diameter of said inner pipe; said absorbing means is sandwiched between said outer pipe and said inner pipe and extends from said aqua chamber into said terra chamber.
Claim 7
Dependent Claim
61 words
A device for supporting flora as claimed in claim 1, wherein said inner pipe is closed at a top thereof and open to an outside of said aqua chamber at a bottom thereof, said inner pipe comprising a plurality of apertures formed in a top portion thereof, such that said terra chamber is communicatable to said outside of said aqua chamber.
