Abstract
Abstract A plant watering device with a self-contained reservoir is placed around a seedling plant to provide a continual flow of water or nutrients to the plant while at the same time conserving the water supply. The plant watering device contains an adjustable drip valve means in fluid communication with the reservoir that delivers water or nutrients dropwise to the plant.

Claim 1
Independent Claim
215 words
A plant watering device adapted to be placed on the ground about the base of a plant for delivering liquid to said plant comprising: a hollow cylindrical member containing an upper section and a lower section, said upper section containing an inner cylindrical wall and an outer cylindrical wall, said outer cylindrical wall further extending downwardly to form said lower section wherein the bottom distal edge of said outer cylindrical wall is adapted to be disposed in surrounding relationship to the ground at the base of the plant, said upper section further cmoprising a top ring-shaped member and a bottom ring-shaped member, said top ring-shaped member and said bottom ring-shaped member being parallel and disposed in surrounding relationship to the corresponding edges of said inner cylindrical wall and said outer cylindrical wall thereby defining an interior chamber for the storage of said liquid, a valve means attached to and extending inwardly from said inner cylindrical wall such that the liquid within said interior chamber can be delivered to said plant, a liquid supply connection means on said upper section adapted to be connected to a liquid supply conduit, said liquid supply connection means being disposed in fluid communication with said interior chamber such that said liquid flows from said supply conduit to said interior chamber.
Claim 2
Dependent Claim
215 words
A plant watering device adapted to be placed on the ground about the base of a plant for delivering liquid to said plant comprising: a hollow cylindrical member containing an upper section and a lower section, said upper section containing an inner cylindrical wall and an outer cylindrical wall, said outer cylindrical wall further extending downwardly to form said lower section wherein the bottom distal edge of said outer cylindrical wall is adapted to be disposed in surrounding relationship to the ground at the base of the plant, said upper section further cmoprising a top ring-shaped member and a bottom ring-shaped member, said top ring-shaped member and said bottom ring-shaped member being parallel and disposed in surrounding relationship to the corresponding edges of said inner cylindrical wall and said outer cylindrical wall thereby defining an interior chamber for the storage of said liquid, a valve means attached to and extending inwardly from said inner cylindrical wall such that the liquid within said interior chamber can be delivered to said plant, a liquid supply connection means on said upper section adapted to be connected to a liquid supply conduit, said liquid supply connection means being disposed in fluid communication with said interior chamber such that said liquid flows from said supply conduit to said interior chamber.
Claim 3
Dependent Claim
72 words
The plant watering device of claim 1 wherein said valve means is comprised of a male threaded member which extends inwardly from said inner cylindrical wall, a corresponding female threaded member, said female threaded member engagingly connected to a flexible hose member, said flexible hose member being connected to an adjustable drip valve, said flexible hose member allowing for the precise positioning of said adjustable drip valve in relationship to said plant.
Claim 4
Dependent Claim
37 words
The plant watering device of claim 2 wherein said liquid supply connection means further contains a cap means which allows for said interior chamber to be completely sealed when said liquid supply conduit is not disposed thereto.
Claim 5
Dependent Claim
17 words
The plant watering device of claim 3 wherein said liquid is comprised of water or plant food.
Claim 6
Dependent Claim
17 words
The plant water device of claim 3 wherien said liquid supply conduit is a conventional garden hose.
Claim 7
Dependent Claim
69 words
The plant watering device of claim 3 wherien said upper section of said hollow cylindrical member further contains a row of apertures disposed in surrounding relationship to the upper distal edge of said inner cylindrical wall such that when said interior chamber is full, said liquid will flow through said apertures in a sprinkling fashion, allowing for said liquid to contact said ground at the base of the plant.
