[0042] Referring initially to FIGS. 1 and 2, presented therein are perspective views of one illustrative embodiment of a plurality of collapsible plant containers 100 of different capacities each disposed in a collapsed configuration, and each disposed in an operable expanded configuration, respectively.

[0043] As may be seen from FIGS. 1 and 2, a collapsible plant container 100 in accordance with the present invention may be provided in any of a variety of sizes or capacities. Specifically, a collapsible plant container 100 in accordance with the present invention may be configured with a capacity to contain an amount of soil S as little as 1 pint, or 1 quart, or 1 gallon.

[0044] Conversely, a collapsible plant container 100 in accordance with the present invention may be configured with the capacity to contain an amount of soil S as large as 10 gallons, or 100 gallons, or 1,000 gallons, or more.

[0045] With particular reference to FIG. 1, a collapsible plant container 100 in accordance with the present invention comprises a collapsible plant container (or simply “collapsible container”) unit 110. A collapsible container unit 110 in at least one embodiment includes a sidewall 113 having upper end 114 and an oppositely disposed lower end 115, and a base (or base member) 111.

[0046] In an embodiment, a collapsible container unit 110 has an open top 116. As may be seen best in the illustrative embodiment of FIG. 6, an open top 116 is at least partially defined by an upper end 114 of the sidewall 113. More in particular, and with continued reference to the illustrative embodiment of FIG. 6, an upper end 114 of a sidewall 113 at least partially defines an upper periphery 117 disposed around the open top 116.

[0047] A sidewall 113 of a collapsible container unit 110 is constructed of a non-rigid flexible material of construction, so as to facilitate disposition of the collapsible container unit 110 from a collapsed configuration, such as is convenient for transport and/or storage, into an operable expanded configuration such that the collapsible container unit 110 can be filled with an amount of soil S sufficient to allow at least one plant P to be potted therein, such as is shown by way of example in the illustrative embodiments of FIGS. 3 and 7. Regardless, a sidewall 113 of a collapsible container unit 110 comprises a material of construction having sufficient tensile strength to contain the amount of soil S needed to support at least one plant P potted therein.

[0048] As such, in at least one embodiment, a sidewall 113 of a collapsible container unit 110 in at least one embodiment of the present invention is constructed of a fabric-like material which is non-rigid and flexible. Utilizing a fabric-like material of construction for a sidewall 113 of a collapsible container unit 110 facilitates assembly, as opposite sides of a sidewall 113 may be simply sewn together along a seam 119, so as to fully form the sidewall 113 of the collapsible container unit 110. A seam 119 in accordance with at least one embodiment of the present invention may be sewn with thread, string, twine, etc. As shown throughout the figures, a sidewall 113 of a collapsible container unit 110 comprises a generally cylindrical configuration, however, it is to be appreciated by those of skill in the art that it is within the scope and intent of the present invention for a sidewall 113 of a collapsible container unit 110 in accordance with the present invention to comprise any of a number of geometric configurations, for example, having a cross-sectional shape of a rectangle, ellipse, a polygon, or a regular polygon. In particular embodiments, for easy construction and horizontal packing/stacking, a square cross-section shape of the side-wall profile can be selected.

[0049] In one embodiment, at least a sidewall 113 (and/or the base member 111) of the collapsible container unit 110 is constructed of a biodegradable material such that the collapsible container unit 110 having an amount of soil S and one or more plants P potted therein to be buried in the ground without the need to remove the collapsible container unit 110 prior to doing so. More in particular, as the sidewall 113 is biodegradable, the roots of the plants P can readily expand and grow through and beyond the boundaries of the sidewall 113 once the plant(s) P and the collapsible container 110 are buried in the ground. In some embodiments, the container can be constructed entirely of biodegradable material.

[0050] In yet one further embodiment of a collapsible plant container 100 in accordance with the present invention, a sidewall 113 of a collapsible container unit 110 is constructed of a material which is permeable to air flow therethrough. As will be appreciated by those of skill in the art, providing aeration to the soil S contained in a collapsible container unit 110 through an air permeable sidewall 113 thereof in accordance with the present invention facilitates plant growth, by as much as 30% to 50%, as a result of air pockets created in the soil which enhance the transfer of water and nutrients to the root system, and thus, to the plant itself, as well as inhibiting damage from disease and/or overwatering thereof. In at least one embodiment, a sidewall 113 of a collapsible container unit 110 is constructed of a woven or knitted material such as, by way of example only, a woven polyethylene material, as is shown best in the illustrative embodiment of FIG. 6. In at least one embodiment, the spacing between the interwoven strands of polyethylene in a woven polyethylene material is approximately the size of a pinhead. In one embodiment, the spacing between the strands of a knitted polyethylene fabric is approximately the size of a pinhead.

[0051] A collapsible container unit 110 in accordance with the present invention further comprises a base member 111 disposed opposite an open top 116 thereof. Looking once again to FIG. 1, in at least one embodiment, a base member 111 comprises a circular configuration. However, and similar to a sidewall 113, it is to be appreciated that it is within the scope and intent of the present invention for a base member 111 to comprise any of a variety of geometric configurations, for example, an elliptical shape, a rectangular shape, a square shape, a polygonal shape (such as hexagon, octagon, etc.). Preferably, the shape of the base member should coincide with the cross-sectional shape of the side-wall.

[0052] A collapsible container unit 110 may also include a base attachment 112 structured to attach a base number 111 to a lower end 115 of a sidewall 113, such as is shown best in the illustrative embodiment of FIG. 6. In at least one embodiment, a base attachment 112 comprises sewing a base member 111 around and along a lower end 115 of a sidewall 113 of a collapsible container unit 110, similar to a seam 119 used the join opposite sides of a sidewall 113 to one another as described hereinabove. Also similar to a seam 119, a base attachment 112 may comprise sewing a base member III around and along a lower end 115 of the sidewall 113 with thread, string, twine, etc.

[0053] Similar to a sidewall 113 of a collapsible container unit 110, a base member 111 is constructed of a non-rigid flexible material of construction, so as to facilitate disposition of the collapsible container unit 110 from a collapsed configuration, such as is convenient for transport and/or storage, into an operable expanded configuration such that the collapsible container unit 110 can be filled with an amount of soil S sufficient to allow at least one plant P to be potted therein. As such, a base member 111 of a collapsible container unit 110 comprises a material of construction having sufficient tensile strength to contain the amount of soil S needed to support at least one plant P potted therein. Also similar to a sidewall 113 of a collapsible container unit 110 in accordance with the present invention, a base member 111 of the collapsible container unit 110 can be constructed of a biodegradable material such that the collapsible container unit 110 having an amount of soil S and one or more plants P potted therein to be buried in the ground without the need to remove the collapsible container unit 110 prior to doing so.

[0054] In some embodiments, the collapsible plant container 100 can include at least one reinforcement member 120 operably interconnected to a portion of a collapsible container unit 110. In at least one embodiment, a reinforcement member 120 is disposed around at least a portion of a sidewall 113 of a collapsible container unit 110 proximate an open top 116 of the collapsible container unit 110 such as is shown best in FIGS. 1, 3, 6 and 7. More in particular, at least one reinforcement member 120 is disposed around a sidewall 113 of a collapsible container unit 110 proximate an open top 116, so as to facilitate maintaining the collapsible container unit 110 in an operable expanded configuration, once again, such as is shown best in FIGS. 1, 3, 6 and 7.

[0055] In at least one embodiment of a collapsible plant container 100 in accordance with the present invention, a reinforcement member 120 comprises an outer reinforcement panel 122 which is disposed around and along an outer sidewall surface 123 of a sidewall 113 of a collapsible container unit 110, as may be seen throughout the figures. As further shown in FIG. 2, in at least one further embodiment a reinforcement member 120 further comprises an inner reinforcement panel 124 disposed around and along an inner side wall surface 125 of the sidewall 113 of the reinforcement attachment 120. In at least one further embodiment, a reinforcement member 120 further comprises an upper reinforcement portion 126 which is disposed along and around an upper end 114 of the sidewall 113 of a collapsible container unit 110, such as is shown throughout. In at least one embodiment, an outer reinforcement panel 122, an inner reinforcement panel 124 and an upper reinforcement portion 126 comprise a unitary construction.

[0056] In at least one embodiment, a reinforcement member 120 comprises a reinforcement attachment 128, such as may be seen in FIG. 2. Similar to a base attachment 112 and a seam 119 in accordance with the present invention, a reinforcement attachment 128 may comprise sewing a portion of an outer reinforcement panel 122 and/or an inner reinforcement panel 124 to a portion of the sidewall 113 of a collapsible container unit 110. Also similar to a base attachment 112 and a seam 119, a reinforcement attachment 128 may comprise sewing a portion of an outer reinforcement panel 122 and/or an inner replacement panel 124 to a portion of a sidewall 113 of a collapsible container unit utilizing thread, string, twine, etc.

[0057] A reinforcement member 120, and more in particular, an outer reinforcement panel 122, an inner reinforcement panel 124 and/or an upper reinforcement portion 126, are constructed of a material exhibiting greater rigidity and less flexibility than a material of construction of a sidewall 113 to which it is attached. As such, the greater rigidity of the reinforcement member 120, and once again, more in particular, an outer reinforcement panel 122, an inner reinforcement panel 124 and/or an upper reinforcement portion 126, will tend to retain an open top 116 of a collapsible container unit 110 in an operable expanded configuration when the collapsible container unit 110 is filled with an amount of soil S into which one or more plants P are potted.

[0058] At least one further embodiment of a collapsible plant container 100 in accordance with the present invention comprises a plurality of reinforcement members 120 disposed around a sidewall 113 of a collapsible container unit 110 at various spaced apart positions between an upper end 114 and a lower end 115 of the sidewall 113. As will be appreciated, providing a plurality of reinforcement members 120 around a sidewall 113 of a collapsible container unit 110 will further facilitate maintaining the collapsible container in an operable expanded configuration when the collapsible container unit 110 is filled with an amount of soil S into which one or more plants P are potted therein.

[0059] A collapsible plant container 100 in accordance with the present invention may further comprise a tensioning mechanism 130 which is operable with an open top 116 of the sidewall 113 of the collapsible container unit 110 to further facilitate maintaining the collapsible container unit 110 in operable expanded configuration once it is filled with an amount soil S. A tensioning mechanism 130 is typically employed on a collapsible container unit 110 having a larger volume capacity such as, by way of example only, 10 gallons, 20 gallons, 30 gallons and more. With reference to FIG. 5, a tensioning mechanism 130 in accordance with at least one embodiment of the present invention comprises a tensioning member 132 which is disposed around and along a sidewall 113 proximate an upper periphery 117 thereof. In at least one embodiment, a tensioning mechanism 130 comprises a tensioning member channel 134 wherein at least a portion of a tensioning member 132 is disposed within a tensioning member channel 134. With reference once again to the illustrative embodiment of FIG. 5 a tensioning member channel 134 is formed between a portion of an outer reinforcement panel 122 of a reinforcement member 120 and a portion of a sidewall 113 of a collapsible container unit 110 proximate an upper periphery 117 thereof.

[0060] In at least one embodiment, a tensioning mechanism 130 comprises a channel aperture 136 through which at least a portion of a tensioning member 132 is disposed into and out of a tensioning member channel 134. In still one further embodiment, a tensioning mechanism 130 comprises a channel aperture reinforcement 138 disposed around and about a channel aperture 136 so as to provide structural integrity thereto. As one example, a channel aperture reinforcement 138 may comprise a grommet affixed around a channel aperture 136. As another example, a channel aperture reinforcement 138 comprise stitching along and around an open periphery of a channel aperture 136 so as to prevent stretching or tearing thereof, by movement of a tensioning member 132 therethrough.

[0061] Looking next with reference to the illustrative embodiment of FIG. 7, a collapsible plant container 100 comprising a collapsible container unit 110 having a considerable volume so as to contain an amount of soil S sufficient to support a large plant P, in this case, a palm tree, potted therein. As may be seen from FIG. 7, the collapsible plant container 100 includes a reinforcement member 120 disposed around and along an open top 116 of the large capacity collapsible container unit 110. As before, a reinforcement member 120 is provided proximate an open top 116 of the collapsible container unit 110 to facilitate maintaining the collapsible container unit in an operable expanded configuration. As further seen in FIG. 7, the collapsible plant container 100 further comprises a tensioning mechanism 130 which is also disposed around and along an open top 116 of the large capacity container unit 110. As may be further seen from FIG. 7, opposite ends of a tensioning member 132 are interconnected, more specifically, tied to one another, so as to maintain at least an outer reinforcement panel 122 of the reinforcement member 120 in operative configuration disposed around and along the sidewall 113 of the collapsible container unit 110 proximate the open top 116 thereof, once again, so as to maintain the collapsible plant container 110 in an operable expanded configuration.

[0062] As illustrated in FIGS. 8A-8B, which are vertical cross-sectional views of an embodiment of a plant container system of the present invention, comprising a collapsible container unit 110 configured and dimensioned to contain an amount of soil needed to support a plant potted therein. The collapsible container unit 110 includes a sidewall having an upper end and a lower end; an open top at least partially defined by said upper end of said sidewall; and a base disposed opposite the open top thereof and attached to said lower end of said sidewall. The collapsible container unit 110 is disposable between an operable expanded configuration and a collapsed configuration. The open top comprises a periphery having a free edge 105 that can be rolled down and up, where rolling down the free edge decreases the capacity of the container unit for containing soil (FIG. 8A), and rolling up the free edge increase the capacity of the container unit for containing soil (FIG. 8B). FIG. 9A is a photo of such an embodiment of collapsible container unit in an open operable expanded configuration, and FIG. 9B is a photo of the collapsible plant container unit shown in FIG. 9A by rolling up the free edge at the top of the container unit. The lower-capacity configuration of the collapsible container unit can be used for a plant at a younger age, whereas the greater-capacity configuration can be used for the plant at later growth stages. By simply rolling up the free edge of the periphery at the top, a planter can add additional soil to the plant container unit as the plant grows, obviating the need to switching to a larger planting pot during the plant growth. Additionally or alternatively, the collapsible container unit can also be constructed with an expandable material or construction, where adding more soil into the container unit can expand the container unit (i.e., in the horizontal direction, in addition or alternative to the vertical direction) to accommodate a plant at a later growth stage.

[0063] As shown in FIG. 8C, the collapsible container unit can further include an engagement element 150 (e.g., an attached loop on the outer sidewall) for improving the stability of the collapsible container unit in the deployed configuration in exposed weather, e.g., during a storm. The plant container system can further include a securing stake 161 or 162 (FIG. 8D), which includes an enlarged top portion (161a) or a bent top portion (162a) to engage the engagement element 150, and a pointed end (161b and 162b) which can be used to be driven to the ground. More than one engagement element 150 can be provided on the collapsible plant container unit, e.g., at a similar height around the sidewall of the container unit, and a plurality securing stakes can be used, each to engage one of the engagement elements. The securing stake can be biodegradable polymeric material, or alternatively, be constructed with common synthetic plastic, metal, metal alloy, wood, or other materials as desired or needed. Alternatively, the engagement element on the collapsible container unit can be a hole 150a (e.g., a grommeted hole) at the base 111 of the collapsible container unit, as shown in FIG. 8E. Alternatively, the collapsible plant container unit does not need to include particular engagement element, and the securing stakes can be directly used to driven through the base of the collapsible plant container unit and into the ground, thereby securing the collapsible plant container unit onto the ground.
