## Title
Adjustable water retention device for a plant pot

## Abstract

An adjustable water retention device for a plant pot has a plant container nesting in a second outer pot, with a facilitated flow of water communicating between the second outer pot and the plant container, wherein the second outer pot rests on a base.

## Background
This invention relates to a plant pot and more particularly to an adjustable water retention device for a plant pot having a water device to provide an adjustable and controllable water flow to soil in the plant pot.
BACKGROUND OF THE INVENTION
For a building, many times it is very desirable to have plants within the building itself. Such plants may be aesthetically pleasing as well as environmentally friendly. The plants can improve the oxygen content of the air in a building, as well provide something attractive to view.
These plants are usually contained in a plant pot. Within the plant pot, is soil suitable for growing plants, such as flowers or other desired vegetation. Plants, even those kept inside, require water and sunlight. To that end, many ways are known to provide those requirements.
Water must be applied to the plant pot in a proper amount, at a proper time, and at a desired level in the soil of the plant pot. With proper watering, the plant or vegetation in the plant pot can thrive. Such thriving plants can improve the air quality and general overall aesthetic desirability of the building in which they are located.
Proper watering of plants can be time-consuming. A regimented schedule of watering combined with desired amounts of water is required. Such control can be problematic. Within a building, it is desired to keep water contained in a very limited area. The water cannot splash outside the container for the plant, without causing a problem in the building. Such a problem can range from a minor stain to structural damage to the building.
By containing the water for the plant within a desired area, great advantages can be obtained. Not only can water be directed in the desired part of the plant, but the amount of water can be efficiently controlled for maximum benefit to the plant. Such conditions complicate providing a proper amount of water to an indoor plant.
SUMMARY OF THE INVENTION

An adjustable water retention device for a plant pot of this invention has a base unit, a bowl or plant container, and a body unit or second outer pot. The base unit supports the body unit while the bowl is nestable in the body unit. The cooperating or interrelated structures of the body unit and the bowl permit water to be applied to a plant contained in the bowl as desired.
Watering of the plant contained in the adjustable water retention device for a plant pot is facilitated by a drain mechanism in the second outer pot, preferably on the inner surface thereof. The plant container includes an opening, such as a screen, to communicate with the drain mechanism. Any user of the adjustable water retention device for a plant pot may water the plant from the top in a standard fashion, such as by pouring water into the plant pot when it contains a plant and the soil therefor, and is assembled as a part of the adjustable water retention device for a plant pot. Such a structure permits a controlled graduated manner for watering a plant.
More specifically, the body unit has a vertical slot in the side. The vertical slot communicates with angled screen in the bowl and permits water to be applied at various levels of the soil in the plant. The base unit can collect excess water and permitted to be used in the plant.
Referring now to the drawings, the following references to specific drawing figures are intended to illustrate without unduly limiting the invention disclosed herein.
Considering now FIG. 1 and FIG. 2, round plant pot 100 is one form of an adjustable water retention device for a plant pot and has a round base unit 110 supporting a round body unit 130. Nesting within the round body unit 130 is round plant bowl 160. Structures of the round base unit 110, round body unit 130, and round plant bowl 160 permit cooperation therebetween in the watering of the plant contained within round plant bowl 160.
Round base unit 110 includes a centrally located trunk 112 to receive round body unit 130. Base spill canal 114 surrounds the centrally located trunk 112 is separated therefrom by base fingers 116. Base fingers 116 protrude upwardly as does centrally located trunk 112. Base side 118 surrounds base fingers 116 putting base fingers 116 between base side 118 and centrally located trunk 112. Circular base bottom 120 supports centrally located trunk 112 and base fingers 116.
Base spill canal 114 provides a gap between base fingers 116 and permits water to flow between base fingers 116 to base side 118 of base bottom 120. Base dam 122, between base fingers 116 provide the base reservoir 124 between base fingers 116 and base trunk 112.
Adding FIG. 3 to the consideration, round bowl 160 has a position notch 162 oppositely disposed from a filter screen 164. Position notch 162 is in lip plane 166 at the top edge of round bowl 160. Filter screen 164 is positioned in bowl side 168. Travel notch 170 is also in lip plane 166 and is oppositely disposed from position notch 162.
Travel notch 170 terminates at left stop 172 or right stop 174 and points in between to limit the movement of round bowl 160 and adjust water flow to the plant. Left stop 172 is oppositely disposed from right stop 174. Position notch 162 may be centrally located relative to travel notch 170 and other points in between left stop 172 and right stop 174. Bowl bottom 176 closes round bowl 160, in order to permit supporting of a plant therein.
With a further consideration of FIG. 4 and FIG. 5, the structure of round body unit 130 becomes clearer. Body unit 130 includes a travel stop 132 in a top edge thereof with water groove 134 therebelow. Opposite travel stop 132 are index numbers 136 to indicate position of round bowl 160.
In the bottom of round body unit 130 are body spill canals 138. Between each pair of body spill canals 138 is a body finger 140 for structure support. Oppositely disposed from the bottom of round body unit 130, is round lip 142. Within round lip 142 at top edge of round body unit 130 are the travel stop 132 with the index numbers 136 oppositely disposed therefrom.
Body bottom 144 includes cradle 146 to receive trunk 112 from round base 110. Body side 148 extends to connect body bottom 144 to round lip 142. Body bottom 144 includes a drain aperture 150 to permit water to flow from round base 110. Index numbers 136 determine first position 152 and last position 154 of round bowl 160 and points therebetween relative to round body unit 130.
Body dam 156 is formed by body spill canals 138 with the use of body fingers 140. Body reservoir 158 is formed between body side 148 and body bottom 144. Such structure permits the desired amount of water storage.
FIG. 6 clarifies the structure of round base unit 110. Round base unit includes trunk 112 centrally located therein with base spill canals 114 separated by base fingers 116. Base side 118 extends upwardly from base bottom 120. Base dam 122 cooperates with base side 118 and base bottom 120 to form base reservoir 124.
In FIG. 7 and FIG. 8, the relationship of body unit 130 and round bowl 160, round plant pot 100 is depicted. Travel stop 132 of body unit 130 is shown in contact with left stop 172 of round bowl 164 for FIG. 7. Notch 152 thereby shows one of index numbers 136. FIG. 8, the other end of index number 136 is shown with travel stop 132 in contact with right stop 174. Furthermore, the relationship of water groove 134 and filter screen 164 are also shown.
With the addition of FIG. 9 and FIG. 10, permanent filter screen 164 is surrounded by a perimeter seal 180 on female snap rim 182. Male snap rim 184 surrounds screen insert 186 and permits screen insert 186 to fit into insert aperture 188.
Turning now to FIG. 11, screen insert 186 is replaced with insert apertures 188 on flipable insert 190 on bowl 160. Flipable insert 190 can serve the same purpose as screen insert 186, changing parts becomes easier.
With FIG. 12 and FIG. 13 an adjustable water retention device for a plant pot is shown as hexagonal pot 200. Hexagonal pot 200 shows a possibility of having a suitable hexagonal shape with hexagonal container 202 receiving hexagonal plant holder 204 in a nestable fashion. On hexagonal container 202, is hexagonal position notch 206 to show hexagonal index numeral 208, depending on the side of the hexagon being used. Hexagonal first position 210 is positioned in hexagonal lip 212 with an index numeral 208 at each side. In hexagonal plant holder 204 is hexagonal position notch 206. Hexagonal water groove 218 contacts first screen aperture 230, second screen aperture 232, third screen aperture 234, fourth screen aperture 236, fifth screen aperture 238 or sixth screen aperture 240 depending on the position desired and considered with hexagonal position notch 242. So hexagonal first position 210 to hexagonal last position 244, and positions therebetween provide a variety of positions relative to the screen apertures.
Turning now to FIG. 14 and FIG. 15, an adjustable water retention device for a plant pot is shown as a square pot 290. Square pot 290 has outer square holder 292 with inner square holder 294 nesting therein. Square pot water groove 302 is positioned in outer square holder 292. The square pot position notch 306 displays square pot first position 308 with square pot lip 310 on outer square holder 292. The square pot position notch 306 is in the square pot lip plane 312. Within inner square holder 294 there is a screen aperture on each side thereof in the form of first screen aperture 320, second screen aperture 322, third screen aperture 324 and fourth screen aperture 326 at different heights to adjust the water. This accounts for the square pot first position 308 to square pot last position 328.
With FIG. 16, the feasibility of adding a snap lock assembly 400 to pot assembly 408 (FIG. 17) is seen. Pot assembly 408 can be circular plant pot 100 (FIG. 1), hexagonal plant pot 200 (FIG. 12), square plant pot 300 (FIG. 14) or any other desired shape for pot assembly 408. Snap lock 400 includes a top snap connection 402 added to centrally located trunk 112. Bottom snap connection 404 involves a modification of cradle 146. In this fashion, top snap connection 402 forms a male female connection with bottom snap connection 404.
With FIG. 17, other variations of an adjustable water retention device for a plant pot beyond circular plant pot 100, hexagonal pot 200, or square pot 290 may be seen. Pot assembly 408 has an assembly base unit 410 communicating with a body unit 430. The body unit 430 is communicates with bowl 460. The base unit 410 feeds to assembly base dam 422. Assembly base dam 422 feeds to assembly base spill canal 414. Assembly base spill canal 414 feeds to assembly base reservoir 424. Assembly base reservoir 424 is connected to assembly bowl 460 through assembly body reservoir 458.
An assembly drain aperture 450 connects assembly base unit 410 to assembly body 430. Assembly bowl 460 is connected to assembly filter screen 464. Assembly filter screen 464 is connected to body unit 430 through water groove 434. Assembly body spill canal 438 is connected to assembly drain aperture 450, assembly body dam 456 and assembly body reservoir 458. Thus, pot assembly 408 may have any desired shape.
