Abstract
Abstract An ornamental plant pot made to resemble an object found in nature and including a construction which allows for drainage of excess liquid from the soil in the pot and enables dissipation of such liquid while precluding return of the liquid to the soil in the pot. The construction includes a concealed trough spaced below drain holes leading from the soil and means permitting the passage of ambient air to the trough and dissipation of the excess liquid.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
304 words
A plant pot comprising a first inner container and a second outer container formed as a unitary assembly, said first container including a side wall, the upper end of which defines an opening into which soil and a plant can be inserted, and a bottom wall which is convex and curves upwardly toward said opening, said bottom wall having drain holes at its periphery whereby excess water readily drains out of said first container, said second container including a side wall having an upper open end which is secured to the upper open end of said first container and is spaced from the wall of said first container to thereby provide a closed annular insulating space between the outer wall of said inner container and the inner wall of said outer container, said second container also including a bottom wall which is spaced below the bottom wall of said first container, the bottom wall of said second container having a central opening which provides communication between the interior of said second container and the outside air, the bottom wall of said second container which defines said central opening extending upwardly from the bottom wall to form an annular waterreceiving trough surrounding said central opening therein, whereby any water, which runs from said first container through said drain holes in its bottom wall and into said annular trough, evaporates therefrom due to air circulation through said central aperture into the space between said first and second containers, the outer surface of the bottom wall of said second container being provided with support legs which raise said plant pot above the surface on which it is supported whereby air can circulate from outside the plant pot into the inside of said plant pot through said central opening in said bottom wall to thereby promote water evaporation.
Claim 2
Dependent Claim
304 words
A plant pot comprising a first inner container and a second outer container formed as a unitary assembly, said first container including a side wall, the upper end of which defines an opening into which soil and a plant can be inserted, and a bottom wall which is convex and curves upwardly toward said opening, said bottom wall having drain holes at its periphery whereby excess water readily drains out of said first container, said second container including a side wall having an upper open end which is secured to the upper open end of said first container and is spaced from the wall of said first container to thereby provide a closed annular insulating space between the outer wall of said inner container and the inner wall of said outer container, said second container also including a bottom wall which is spaced below the bottom wall of said first container, the bottom wall of said second container having a central opening which provides communication between the interior of said second container and the outside air, the bottom wall of said second container which defines said central opening extending upwardly from the bottom wall to form an annular waterreceiving trough surrounding said central opening therein, whereby any water, which runs from said first container through said drain holes in its bottom wall and into said annular trough, evaporates therefrom due to air circulation through said central aperture into the space between said first and second containers, the outer surface of the bottom wall of said second container being provided with support legs which raise said plant pot above the surface on which it is supported whereby air can circulate from outside the plant pot into the inside of said plant pot through said central opening in said bottom wall to thereby promote water evaporation.
Claim 3
Dependent Claim
32 words
The plant pot of claim 1 wherein said second container is irregularly shaped so that the plant pot has the shape and appearance of a rock or other object found in nature.
