Definitions

  • the correct amount of fluid varies not only among different types of plants but with the particular environment in which the plant is growing, it is a time consuming and laboured process to manually supply the necessary fluids.
  • An automatic device providing the necessary moisture to the plant is therefore highly desirable, especially if the fluid is dispensed on demand.
  • Fluid dispensing plant containers fall into different categories. Some use fluid administered by pipes, some have porous inner containers where the fluid seeps through the container wall. Others have a reservoir located in the base of the container which relies on capillary action or fabric wicks to deliver the fluid to the growing media from the reservoir. None of these designs use hydrostatic pressure and buoyancy aiding fluid delivery or a delivery valve.
  • Some self-regulating automatic dispensing planters incorporate vacuum sealed reservoirs located within the container wall, using a sensor located within the growing media to activate the flow of fluid through apertures in the bottom of the planter. It is essential that the flexible stopper used to fill the reservoir is tightly sealed thus maintaining the vacuum within.
  • a buoyancy operated automatic self-watering planter comprising a valve located between an inner receptacle and an outer receptacle. With the valve open, fluid from a reservoir located between said receptacles is dispensed aided by hydrostatic pressure through an aperture located in the base of the inner receptacle.
  • the proposed design is fully automatic and self-regulating, preferably dispensing fluid from a reservoir via a valve only when the receptacle containing the growing media and plants drops in weight due to evaporation and plant fluid demand.
  • the valve closes when the receptacle containing the plant and media increases to a certain weight due to the intake of fluid.
  • the valve operates regularly when air temperatures are high, rarely in cool and/or wet conditions.
  • receptacles preferably polymers such as polymethyl methacrylate, polycarbonate, acrylic, polyester or styrene acrylonitrile copolymer, which are all solid and translucent.
  • various materials offer excellent sealing properties for the valve, such as Nitrile NBR, Chloroprene, Fluoroelastomers FPM/FKM.
  • the planter of the present invention allows easy assessment of fluid content due to the translucent nature of the outer receptacle. Indeed, the fluid content of the entire planter can be assessed as the moisture content of the growing media is always consistent as long as there is fluid within said reservoir, the minor variable being the weight of the plants.
  • the planter lends itself to a variety of environments, be it a planter that hangs by means of chains as with a hanging basket, affixed to walls, or free standing planters located on the floor or upon furniture.
  • the planter will also locate itself into a variety of stands utilising the protrusion on the outside of the outer receptacle for alignment.
  • a variety of shapes may be used, be it cylindrical, conical, hexagonal, square, etc, all using the floating inner receptacle and valve design.
  • Fluid addition to planters is usually from above, the present invention reverts this insofar that fluids are introduced from below resulting in the planter being saturated in the lower part and drier in the top section of the planter.
  • This embodiment allows considerably reduced evaporation to atmosphere from the media surface. This could be deemed as a water saving feature.
  • the planter of the present invention being of the type described could negate the requirement of a translucent outer receptacle allowing, possibly more aesthetic materials of a non-translucent nature.
  • a transparent tube could be attached to the side of the planter entering beneath; this would provide indication of fluid level within the reservoir and by default the moisture content of the inner receptacle.
  • a floating dipstick could indicate when the reservoir level is low or empty.
  • the addition of plant food could be measured as said food could be introduced directly into the reservoir avoiding the possibility of spillage if introduced to the planter conventionally from above.
  • the invention allows the option of multiple planters being watered from one source should connection be made by lengths of tubing; fluid would cascade from planter to planter until all reservoirs are replenished. This system could easily be automated by fitting a simple ballcock valve to the final planter.
  • the present invention would save fluid spills due to zero leakage, unlike some hanging containers where excessive spills are unavoidable.
  • Figure 1 shows an embodiment of the planter seen from above in accordance with the present ' invention.
  • FIG. 2 shows an embodiment of the planter in section in accordance with the present invention with the valve closed.
  • FIG. 3 shows an embodiment of the planter in section in accordance with the present invention with the valve open.

  • Figure 5 shows the planter from Figure 4 in section.

  • a planter comprising:
  • An Inner Receptacle (1) manufactured from injection moulded plastic having an Aperture (a) in its base.
  • An Outer Receptacle (2) manufactured from injection moulded plastic having a Depression or a Raised Ring (b) located centrally inside for positioning of the Valve (3) made from a suitably flexible material.
  • the shape of the Depression/Raised Ring (b) and the Valve (3) may be varied.
  • Three Cut Outs (h) are equally spaced around the periphery of the Flange (d) for the option of suspending the invention in a similar manner to a hanging basket.
  • a Raised Ring (f) is located centrally inside the Inner Receptacle (1 ) for the accommodation of a loose fitting Disc (5) which covers the Aperture (a) preventing blockages from aggressive root systems.
  • a loose fitting Disc (5) which covers the Aperture (a) preventing blockages from aggressive root systems.
  • One or a plurality of contoured cut-outs in the flange of the Inner Receptacle (i) represents the Fluid Inlets (e). Note that the Disc (5) has been omitted on some diagrams for clarity.
  • the Inner Receptacle (1 ) containing plants and plant Growing Media (g) is placed inside the Outer Receptacle (2), allowing the underneath of the Inner Receptacle (1 ) to make contact with the Valve (3). Fluid is then introduced into the Fluid Inlet (e) thus filling the Reservoir (c).
  • the level of the Reservoir (c) may be determined by either a floating Dipstick (6) as shown in Figure 5 or a Tube (6) exiting from the base or near the base of the Outer Receptacle (2) as shown in Figure 7

Abstract

L'invention concerne une jardinière à arrosage automatique, fonctionnant par flottabilité, qui comporte un logement intérieur placé à l'intérieur d'un logement plus grand 2 séparés par une vanne 3. L'espace entre les deux logements constitue un réservoir c dans laquelle le fluide est introduit. Si le poids du logement intérieur 1 et du contenu est inférieur à une certaine valeur, le logement intérieur 1 flottera, ce qui ouvrira la vanne 3 afin de permettre au fluide de pénétrer depuis le réservoir par une ouverture a dans le récipient intérieur 1, à l'aide de la pression hydrostatique. Si le poids du logement intérieur 1 et son contenu est supérieur à une certaine valeur, le logement intérieur 1 va compenser l'effet de flottabilité activé par le réservoir c en abaissant progressivement le récipient intérieur 1 sur la vanne 3 et va créer une étanchéité, empêchant ainsi l'écoulement du fluide. Une vis de vidange 4 est reliée à la cuve extérieure afin de permettre à la cuve intérieure de se vider librement dans des conditions excessivement humides si la jardinière est utilisée à l'extérieur.
