Abstract
Abstract A self-watering plant pot consisting of an outer pot, a liner of translucent or semi-translucent material that fits within the outer pot, a soil platform assembly that divides the liner into a soil compartment and a water reservoir, an optional float positioned in the water reservoir, and a water delivery channel for allowing water and air to be introduced into the water reservoir. The water delivery channel can be a water delivery tube extending upward from the soil platform. The outer pot is typically opaque and includes a side window opening near its base. The water level in the water reservoir and, if a float is employed, the position of the float are visible through the liner and window opening in the outer pot. Water is conveyed from the water reservoir to the soil via capillary action.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
169 words
A self-watering plant pot apparatus having an internal water reservoir and a soil compartment which comprises: a. an outer opaque pot with an opening in the side wall of the outer pot; b. a transparent or semi-transparent liner shaped to be removably received within the outer pot and having a side wall and a bottom wherein the bottom portion is not permeable to water, said liner extending upward from the base of said outer pot; c. a soil platform shaped and sized to be removably received within the liner and which on insertion into the liner is supported therein to form a water reservoir in the bottom portion of the liner below the platform and a soil compartment in the liner above the platform; d. a water delivery channel allowing delivery of water from outside of said pot to said internal water reservoir; whereby said water level within said reservoir can be observed from the outside of said outer pot through said opening in the outer pot side wall.
Claim 2
Dependent Claim
169 words
A self-watering plant pot apparatus having an internal water reservoir and a soil compartment which comprises: a. an outer opaque pot with an opening in the side wall of the outer pot; b. a transparent or semi-transparent liner shaped to be removably received within the outer pot and having a side wall and a bottom wherein the bottom portion is not permeable to water, said liner extending upward from the base of said outer pot; c. a soil platform shaped and sized to be removably received within the liner and which on insertion into the liner is supported therein to form a water reservoir in the bottom portion of the liner below the platform and a soil compartment in the liner above the platform; d. a water delivery channel allowing delivery of water from outside of said pot to said internal water reservoir; whereby said water level within said reservoir can be observed from the outside of said outer pot through said opening in the outer pot side wall.
