Abstract
Abstract A vessel for automatically sustaining vegetation includes a lower container for storing a reservoir of liquid, an upper container for supporting the vegetation and receiving liquid from the lower container, and a flow regulator for controlling the flow of liquid to the vegetation. The upper container is engageable with the lower container and includes a stem, defining at least one passageway, for extending into the liquid. The flow regulator includes a member which defines a flow port and which is rotatably attached to the stem of the upper container. In one embodiment the flow regulator may be controlled from outside the vessel by means of a control arm extending from the member. The upper container preferably includes drain holes permitting the drainage of excess liquid from the vegetation and permitting aeration of the vegetation, while the lower container preferably is transparent for viewing the liquid level and includes a fill/drain opening for adding liquid without disassembling the vessel and for permitting the drainage of excess liquid from the lower container. The upper and lower containers are preferably tapered in their cross-sectional dimensions from top to bottom to permit the nesting of a plurality of such vessels and thereby facilitate handling, storage, and shipment. The cross-sectional dimensions of the upper and lower containers are additionally preferably arranged so that the assembled vessel presents a unitary appearance with a constant taper from top to bottom.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
196 words
A vessel for supporting and automatically providing liquid to vegetation, comprising: (a) a lower container for storing a reservoir of liquid; (b) a vegetation supporting upper container having upper and lower portions of relatively larger and smaller cross-sectional areas respectively, said upper portion engageable with said lower container, said lower portion extending from said upper portion and having a shaped end, said lower portion also defining near said end at least one passageway extending into said lower container for conveying a flow of liquid to the vegetation; and (c) a flow regulator movably secured to said lower portion and defining at least one flow port of dimensions having a selected relationship to the cross-sectional dimensions of said passageway, said flow regulator configured substantially in the shape of said end to selectively enable at least partial alignment of said passageway and said flow port upon relative motion between said lower portion and said flow regulator, said flow regulator further including means actuable from a position external of said vessel for moving the flow regulator relative to said portion, thereby permitting the regulation of the flow of said liquid without separating the upper container from the lower container.
Claim 2
Dependent Claim
196 words
A vessel for supporting and automatically providing liquid to vegetation, comprising: (a) a lower container for storing a reservoir of liquid; (b) a vegetation supporting upper container having upper and lower portions of relatively larger and smaller cross-sectional areas respectively, said upper portion engageable with said lower container, said lower portion extending from said upper portion and having a shaped end, said lower portion also defining near said end at least one passageway extending into said lower container for conveying a flow of liquid to the vegetation; and (c) a flow regulator movably secured to said lower portion and defining at least one flow port of dimensions having a selected relationship to the cross-sectional dimensions of said passageway, said flow regulator configured substantially in the shape of said end to selectively enable at least partial alignment of said passageway and said flow port upon relative motion between said lower portion and said flow regulator, said flow regulator further including means actuable from a position external of said vessel for moving the flow regulator relative to said portion, thereby permitting the regulation of the flow of said liquid without separating the upper container from the lower container.
Claim 3
Dependent Claim
52 words
The vessel of claim 1, wherein said lower container includes an aperture and the moving means of said flow regulator comprises a control lever attached at an inner end to that portion of the flow regulator which defines the flow port, and having an outer end extending at least to said aperture.
Claim 4
Dependent Claim
35 words
The vessel of claim 1, wherein said lower portion is a protruding stem and said flow regulator comprises a cap rotatably attachable to said stem, said cap having an aperture for defining said flow port.
Claim 5
Dependent Claim
61 words
The vessel of claim 3, wherein said stem defines an annular ridge disposed upon its outer surface and wherein the cap defines an annular groove disposed upon its inner surface, said groove cooperating with said ridge when the cap is attached to the stem to effect a fluid-tight seal between said cap and said upper container while permitting relative rotation therebetween.
Claim 6
Dependent Claim
108 words
The vessel of claim 1, wherein said upper container comprises a main body for supporting the vegetation and said lower portion extends from a bottom surface of the main body, said main body defining at least one drainage hole in the bottom surface, and wherein said lower container includes at least one fill/drain opening located below the level of said drainage hole and above the level of said passageway, thereby permitting excess liquid to drain from said upper container, permitting the replenishment of liquid in said lower container, and permitting aeration of said vegetation even when said vessel contains a full reservoir of liquid in the lower container.
Claim 7
Dependent Claim
27 words
The vessel of claim 5, wherein said lower container further comprises a splash shield disposed subjacent said fill/drain opening to reduce the inadvertent spillage of liquid therethrough.
Claim 8
Dependent Claim
36 words
The vessel of claim 1, wherein said lower container is externally dimensioned to fit at least partially within said upper container, thereby permitting the nesting of a plurality of said vessels for facilitating storage and shipment.
Claim 9
Dependent Claim
69 words
The vessel of claim 1, wherein the diameter of said upper container diminishes from a larger diameter at the uppermost level of said upper container to a medium diameter where said upper container engages said lower container and the diameter of said lower container diminishes from said medium diameter where said lower container engages said upper container to a smaller diameter at the lowermost level of said lower container.
Claim 10
Dependent Claim
44 words
The vessel of claim 8, wherrein said upper container further comprises: an annular shoulder extending radially inward, the lower surface of said annular shoulder being engageable with the upper surface of said lower container for firmly supporting said upper container on said lower container.
Claim 11
Dependent Claim
22 words
The vessel of claim 1, wherein said lower container is transparent, thereby permitting the viewing of said liquid from outside the vessel.
