Abstract

Abstract A device for the continuous watering of plants, including a reservoir provided at its lower part with a base having at least one opening, the reservoir being connected by its base to a stabilization leg which contains an absorbing or filtering material and ends into a tapered soil penetration guide. The stabilization leg has at least one blade connected to a central hollow tube containing the absorbing or filtering material and having at least one opening provided for creating a communication between the absorbing or filtering material and the soil. The absorbing or filtering material is positioned in such a way that at least one wick connected to the reservoir and suspended above the absorbing or filtering material acts as a drip.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 157 words
A device for the continuous watering of plants, comprising a reservoir provided with a base having at least one opening defined therein, an elongate stabilization leg joined to said reservoir by said base, said stabilization leg, longitudinally remote from said base, terminating in a tapered soil penetration guide, said stabilization leg comprising a central hollow tube aligned with said at least one opening and containing an absorbing material, at least one blade fixed to said tube and extending laterally therefrom, said central hollow tube having a longitudinal aperture defined therein and offset from said at least one blade, at least one wick extending through said opening in said base and extending below said opening to a point in spaced relation above said absorbing material for a drip transfer of watering liquid from said reservoir to said absorbing material in said central hollow tube for subsequent distribution to the plant through said longitudinal aperture in a controlled manner.
Claim 2
Independent Claim 157 words
A device for the continuous watering of plants, comprising a reservoir provided with a base having at least one opening defined therein, an elongate stabilization leg joined to said reservoir by said base, said stabilization leg, longitudinally remote from said base, terminating in a tapered soil penetration guide, said stabilization leg comprising a central hollow tube aligned with said at least one opening and containing an absorbing material, at least one blade fixed to said tube and extending laterally therefrom, said central hollow tube having a longitudinal aperture defined therein and offset from said at least one blade, at least one wick extending through said opening in said base and extending below said opening to a point in spaced relation above said absorbing material for a drip transfer of watering liquid from said reservoir to said absorbing material in said central hollow tube for subsequent distribution to the plant through said longitudinal aperture in a controlled manner.
Claim 3
Dependent Claim 31 words
The device as claimed in claim 1 including two opposed half-shells clamped about said wick and fixed within said opening in said base for a fixed positioning of said wick therein.
Claim 4
Dependent Claim 31 words
The device as claimed in claim 1 wherein said at least one blade comprises multiple blades connected to and extending axially along said central hollow tube at peripherally spaced points thereabout.
Claim 5
Dependent Claim 18 words
The device as claimed in claim 3 wherein said blades are substantially longitudinally coextensive with said stabilization leg.
Claim 6
Dependent Claim 27 words
The device as claimed in claim 4 wherein additional longitudinal apertures are provided, said apertures being positioned with at least one between each pair of adjacent blades.
Claim 7
Dependent Claim 18 words
The device as claimed in claim 5 wherein said apertures are substantially longitudinally coextensive with said stabilization leg.
Claim 8
Dependent Claim 28 words
The device as claimed in claim 5 wherein said base has a concave upper face above which said wick projects for extension of said wick into said reservoir.
Claim 9
Dependent Claim 28 words
The device as claimed in claim 1 wherein said base has a concave upper face above which said wick projects for extension of said wick into said reservoir.
Claim 10
Dependent Claim 15 words
The device as claimed in claim 1 wherein said wick is of a synthetic material.
Claim 11
Dependent Claim 16 words
The device as claimed in claim 1 wherein said absorbing material is of a sponge-like material.
