DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 illustrates a vertically stackable plant tower 10 constructed in accordance with the present invention. The stackable plant tower, in the preferred embodiment, comprises a plurality of plant container modules 20 which are adapted such that a plurality of plant container modules 20 can be nested together to save space for shipping and storage. Further, the plant container modules 20 are also adapted such that a plurality of plant container modules can be stacked together, thereby forming a stacked plant tower. While plant container modules can have any geometric shape, in the preferred embodiment, the plant container modules 20 are lobate. In addition to the stacked plant container modules 20, the vertically stacked plant tower 10 includes a water management assembly in cooperation with the stacked plant container modules 20 for directing a flow of water to each of the stacked plant container modules 20.

In this regard, each plant container module 20 includes an upwardly projecting wall member 25 having an upper rim 30. The upwardly projecting wall member 25 is configured with an array of alternating lobes 40 and indentations 60. It should be appreciated that the terms “lobe”, “lobate” or “lobed” as used herein encompasses broad, rounded lobes, angular and/or substantially linear lobes, narrow flutes, or other similar shapes defined between indentations that can receive planting medium and plants. Further, while in the preferred embodiment, illustrated in FIGS. 1-11, the lobes are broader than the indentations, the present invention contemplates that the lobes could be narrower than the indentations, for example, as illustrated in FIG. 12, for reasons such as aesthetic appeal. Additionally, bent wire cage members 220 can be provided. Wire cage members 220 can be positioned at the edges of the lobes and can be used to support large plants, such as tomatoes. Additionally, wire cage members 220 can be used to support a plastic cover/tent (not shown), providing an air space between the plastic cover and the plant container modules 20 such that the stacked plant tower 10 becomes a stacked greenhouse. Alternatively, wire cage members 220 can support a mesh covering to protect the plants planted in stacked plant tower 10 from foraging animals.

Plant container module 20 also includes a bottom wall 80 upon which is provided an upwardly extending inverted funnel member 90. Bottom wall 80 is perforated by at least one drainage-hole member 100. Drainage-hole member 100 allows for drainage if the plant medium contained within plant container module 20 becomes saturated. However, as will be described in greater detail below, drainage-hole member is not the only means for managing water flow through the stacked plant tower 10. Disposed at the top of the plant tower 10 when assembled is, preferably, a water bowl 150 defining a reservoir for receiving water. Water bowl 150 has at least one, and preferably a plurality of weep-hole members 155 disposed therein. Additionally, water bowl 150 includes a centrally disposed hole member 105 adapted to receive at least the upper portion of the inverted funnel member 90 allowing the water bowl 150 to be carried by, or supported by, inverted funnel member 90. Further, in the preferred embodiment, a water tray 110, defining a diffuser, having at least one, and preferably a plurality of weep-hole members 120 disposed therein and a centrally disposed hole member 125 adapted to receive at least the upper portion of the inverted funnel member 90 allowing the water tray 110 to be carried by, or supported by, inverted funnel member 90.

Further, a funnel extension member 115 is provided which is in register with centrally disposed hole member 105 and which extends into the interior volume of water bowl 150. Additional funnel extension members 115 are provided which extend into the interior volume of the water trays 110 and which are in register with centrally disposed hole members 125. In this regard, in the preferred embodiment, as illustrated in FIG. 5 and FIG. 8, a funnel extension member 115 is molded into the bottom of the water bowl 150 and into the bottom of the water trays 110. However, it will be recognized that funnel extension member 115 could be integral with the inverted funnel member 90. Further, in the preferred embodiment the upper end of funnel extension member 115 is irregularly shaped to substantially prevent a vapor lock at the top of funnel member 90 thereby facilitating the flow of water into the inverted funnel member 90.

As stated above, plant container modules 20 are adapted to be stacked one upon another. Accordingly, plant tower 10 includes connectors for securing the stacked plant container modules 20 to one another. In this regard, in the preferred embodiment, as seen more clearly in FIG. 3 and FIG. 10, the plant container modules 20 are provided with a plurality of foot members 130 disposed on the exterior surface of bottom wall member 80, preferably such that a foot member 130 is disposed proximate a lobe 40. Each foot member 130 has a groove member 135 disposed therein. Each foot member 130 is positioned such that when two plant container modules 20 are stacked one upon the other, the groove members 135 disposed in each foot member 130 will receive a portion of the rim 30 proximate an indentation 60. Further, groove members 135 are dimensioned and adapted to receive rim 30 in a tight frictional fit thereby releasably securing the stacked plant container modules 20 to one another. In the preferred embodiment, water bowl 150 is also provided with similar groove members 140 for securing water bowl 150 to the upper most plant container module 20.

In an alternate embodiment, illustrated in FIG. 12, stackable plant tower 10′ is illustrated in which plant container modules 20′ have flute shaped lobes 40′ and broad indentations 60′. FIG. 12 also illustrates an alternate configuration for adjoining stacked plant container modules 20′. In this regard, plant container modules 20′ also include a locking tab 170 carried by at least one indentation 60′. Bottom wall member 80′ includes a slot member 190 disposed proximate the bottom of at least one lobe 40′. In this manner locking tab 170 is received by a slot member 190 on an adjoining container module 20′ in order to secure the two container modules 20′ to each other. Those skilled in the art will appreciate that, preferably, each indentation 60′ carries a locking tab 170 and each lobe 40′ has an associated slot member 190 in close proximity thereto.

When a plurality of plant container modules 20 are stacked in a vertical array, see for instance FIG. 11, and the water bowl 150 is attached to the upper most plant container module 20, the water bowl 150 is in fluid communication with each water tray 110 carried by the inverted funnel member 90 of each plant container module 20. And, further, the water tray 110 and funnel member 90 of a given plant container module 20 are in fluid communication with the water tray 110 and funnel member 90 of the adjoining plant container module 20, as most clearly illustrated in FIG. 11. In this manner, as water bowl 150 receives water, either rain water or water being poured therein, water bowl 150 begins to fill and a portion of water drips through the weep-hole members 155 disposed in the bottom of the water bowl 150 into soil medium 200A contained in plant container module 20A. As the level of water in the water bowl 150 rises above the top of funnel extension member 115A, water begins flowing into the inverted funnel member 90A. Inverted funnel member 90A directs the flow of water into water tray 110B.

As water tray 110B begins to fill, a portion of water drips through the weep-hole members 120 disposed in the bottom of the water tray 110B into soil medium 200B contained in plant container module 20B. As the level of water in the water tray 110B rises above the top of funnel extension member 115B, water begins flowing into the inverted funnel member 90B. Inverted funnel member 90B directs the flow of water into water tray 110C. As water tray 110C begins to fill, a portion of water drips through the weep-hole members 120 disposed in the bottom of the water tray 110C into soil medium 200C contained in plant container module 20C. As the level of water in the water tray 110C rises above the top of funnel extension member 115C, water begins flowing into the inverted funnel member 90C. Inverted funnel member 90C directs the flow of water into water tray 110D. Similarly, as water tray 110D begins to fill, a portion of water drips through the weep-hole members 120 disposed in the bottom of the water tray 110D into soil medium 200D contained in plant container module 20D. As the level of water in the water tray 110D rises above the top of funnel extension member 115D, water begins flowing into the inverted funnel member 90D. Inverted funnel member 90D directs the flow of water into water tray 110E. And finally, in the illustrated example of a stacked plant tower 10 incorporating five separate plant container modules 20, as water tray 110E begins to fill, a portion of water drips through the weep-hole members 120 disposed in the bottom of the water tray 110E into soil medium 200E contained in plant container module 20E. If the level of water in the water tray 110E rises above the top of funnel extension member 115E, water begins flowing into the inverted funnel member 90E.
