WO 01/35722 PCT/AU00/01389 -l Improvements in or relating to plant growth containers Field of the invention The present invention is directed to improvements in or relating to plant growth containers, and is more particularly directed to improvements to the formation of a walled plant growth container for air root pruning of the plant.
Background of the invention Air root pruning of the root structure of a growing plant is well-known from, for example, the specifications of Australian Patent Nos 611917, 629067, 674543 and that of Petty Patent No 701466.
These specifications all generally disclose a plant growth container having a side wall formed from a cuspated sheet having holes formed in at least some of the outwardly projecting cusps to facilitate air root pruning of the root structure of a plant grown within the container. The side wall of the container is generally formed from a plurality of similar panels which are fastened together in various ways.
For example, Australian Patent No 611917 describes a method and container for growing transplantable plants, the container comprising a set of identical upwardly extending side panels which are removably joined together at their vertical edges by two sets of mortise and tenon joints positioned in spaced relationship on the panels. One set of mortise and tenon joints when connected is said to prevent lateral movement between the side panels, whilst the second set is said to prevent longitudinal movement therebetween.
Australian Patent No 629067 describes fastening means to hold a cuspated sheet in overlapping, nested engagement. The fastener disclosed comprises a rivet or releasable fastening means in the form of a strap or tie which passes through aligned holes at the overlap, or an adjustable strap or belt which extends around the circumference of the container.
Australian Patent No 674543 describes a resilient fastener in the form of a clip which engages either side of two overlapping edge portions of a panel which form the vertical sides of the plant growth container.
Australian Petty Patent No 701466 describes a cuspated sheet being arranged with a first edge portion overlapping either an opposite second edge portion of the same sheet or a second edge portion of another similar sheet, the protuberances of the outer surface of the second edge portion nesting within the recesses of the inner surface of the first edge portion to align openings in the protuberances at the overlap. At least one screw threaded fastener is located within the aligned openings, the fastener having a helical threaded shank and an enlarged head on one end of the shank, the threads having a sufficiently large depth between a crest of the thread and the shank to enable, in use, secure retention against the inner surface of the overlapping portions of the sheet or sheets thereby securing the overlapping edge portions together.
It has been observed that the fastening arrangements disclosed in the above specifications have a number of shortcomings. In the case of fasteners in the form of screws or rivets, it has been observed that the formation of a container using fastening means in that form can be time consuming, particularly in cases where a drill, rivet gun or screw driver is required to secure the panels together. Fastening of the container in that way can also lead to significant difficulties in readily dismantling the container.
In the case of a fastener in the form of a wire clip, the open-ended nature of the clip can lead to hand or finger damage to a user when attempting to secure the clip to the container. In addition, the strength of the fastening is to a great extent dependent on the degree of resilience of the material from which the clip is formed, which is likely to degrade over time, reducing the efficacy of the clip. Furthermore, the clip arrangement 20 can require significant overlap of the edge portions of a sheet or adjacent sheets, at least partially (and in some cases significantly) reducing the number of cuspations available for

air root pruning.
S0The foregoing does not constitute an admission as to the state of common general knowledge in the art as it existed at the priority date of a claim of this application.

The present invention provides in another separate embodiment a panel for use as a siole.
wall of a plant growth container, the panel comprising a flexible, elongate cuspated sheet having apertures formed in at least some of the outwardly projecting cusps to facilitate air root pruning of the root structure of a plant grown within a container, the sheet including opposed non-cuspated edge sections, the non-cuspated edge sections being cooperable with one another or with a complementary non-cuspated edge section of an adjacent sheet, the cooperable edge sections when brought together forming a guideway for a rod, the guideway extending in a direction substantially parallel to the edge sections, the rod passing along the guideway to progressively or sequentially draw the edge sections together and releasably hold the edge sections whereby in use to form a side wall of the container.
The present invention provides in another separate embodiment a plant growth container having at least one panel for forming a side wall of the container, the panel comprising a flexible elongate cuspated sheet having apertures formed in at least some of the outwardly projecting cusps to facilitate air root pruning of the root structure of a plant S 25 grown within a container, the sheet including a non-cuspated edge section, the noncuspated edge section being cooperable with a complementary edge section of the same "'°sheet or of an adjacent sheet, the cooperable edge sections forming a guideway for a rod, "°"the guideway extending in a direction substantially parallel to the edge sections, the rod oo. passing along the guideway to progressively or sequentially draw the edge sections o 30 together and releasably hold the edge sections whereby to form a side wall of the container.
The present invention provides in another separate embodiment a plant growth container having at least one panel for forming a side wall of the container, the panel comprising a flexible elongate cuspated sheet having apertures formed in at least some of the outwardly projecting cusps to facilitate air root pruning of the root structure of a plant grown within a container, the sheet including opposed non-cuspated edge sections, the arsmMOI 11544302vl 305018370 9.07.2004 non-cuspated edge sections being cooperable with one another or with a complementary non-cuspated edge section of an adjacent sheet, the cooperable edge sections when brought together forming a guideway for a rod, the guideway extending in a direction substantially parallel to the edge sections, the rod passing along the guideway to progressively or sequentially draw the edge sections together and releasably hold the edge sections whereby to form a side wall of the container.
The arrangement is preferably such that the rod is capable of being inserted in the guideway and passed along the guideway. It will be readily apparent to the skilled addressee that the rod may be of any convenient cross-sectional shape. The rod may be tapered. The rod may be substantially circular or substantially non-circular in crosssection. The rod may be cross shaped in cross-section. The arrangement may be such that the external cross-sectional dimension of the holding means is greater in one direction than the internal cross-sectional dimension of the guideway. In this arrangement the action of the holding means passing along the guideway may have the effect of providing a tauter connection between the edge sections of the same sheet or of adjacent sheets. This can be of benefit in cases where the tolerances of the sheet manufacturing process are variable, which can require as a consequence corresponding adjustment of the relative distance between edge sections of a sheet or of an adjacent sheet when brought together for assembly.
•o• 20 The rod may be provided with a grip. The grip may be in the form of an element extending transversely to the longitudinal axis of the rod.
The rod may be rotatable in the guideway. Rotation of the rodin the guideway has the effect of urging the edge sections toward or away from one another in an embodiment where the external cross-sectional dimension of the rod is greater in one direction than i 25 the internal cross-sectional dimension of the guideway. Rotation of the rod in the ••o guideway can be to any suitable degree, and is typically through up to about 1800, and more typically through about 90 0 A rod may include a recess engageable with a rim of the base. Engagement of the recess io with the rim may be effected by rotation of the rod in the guideway to locate the rim in 30 the recess. This arrangement assists in facilitating a secure connection between edge sections.
In one particularly preferred embodiment the holding means comprises an elongated rod having a substantially oval cross-section, the long dimension of the oval being greater than a width dimension of the guideway in any direction, the rod being rotatable in the guideway to adjust the distance between edge sections of the same sheet or of adjacent arsmM0111544302vl 305018370 9.07.2004 sheets whereby to adjust a width dimension of a container having a side wall formed in that manner.
Other holding means arrangements are envisaged within the scope of the invention.
A plant growth container according to the invention may include one or more handles.
The handle may be attachable to a panel as described. In an alternative embodiment the handle may be attachable to holding means according to the invention.
The handle may be pivotable relative to the component to which it is attached. The handle may comprise a loop. The loop may be of sufficient dimension or diameter to fit over at least one cuspation of the sheet to provide an additional means of maintaining the structural integrity of the container when assembled.
A guideway according to the invention may take any suitable form. It may comprise a Srecess. It may comprise a channel. The channel may comprise an open or a closed channel. The boundaries defining the channel may be deformable.
The arrangement may be such that the cooperable or engageable edge sections form a guideway for the holding means which comprises a pair of opposed channels or recesses.
In this embodiment the holding means comprises a bifurcated rod, the branches of the rod passing along respective ones of the opposed channels or recesses.
oo A guideway according to the invention may be tapered so that the internal dimension of :the tapered section of the guideway is less than the external dimension of the holding means passing along that part of the guideway. In this arrangement the action of the holding means passing along the guideway may have the effect of providing a tauter connection between the edge sections of the same sheet or of adjacent sheets. Other guideway arrangements are envisaged within the scope of the invention.
SIn one particularly preferred embodiment the movement of the rod along the guideway o. 25 facilitates a sequential wedge action, that is, the arrangement of the guideway and the rod

Description of the drawings S* arsm M011154 4 302vl 305018370 9.07.2004 WO 0135722 PCT/AU00/01389 The invention will now be further explained and illustrated by reference to the accompanying drawings. In the drawings, in which like integers are given like numerals: Figure 1 is a perspective view of a panel according to an embodiment of the present invention; Figure 2 is a side elevation of a panel according to an embodiment of the present invention; Figure 3 is a perspective view of the panel of Figure 2; Figure 4 is a perspective view in close-up of panel edge sections according to an embodiment of the present invention; Figure 5 is a perspective view in close-up of the edge sections of Figure 4 and further showing a plant growth container base; Figure 6 is a perspective view of part of the wall of a plant growth container when assembled according to an embodiment of the present invention; Figure 7 is a perspective view of a partly disassembled plant growth container showing a holding means in the form of a rod partly withdrawn from the guideway; Figure 8 is a cut-away end cross-section of a guideway and holding means in the form of a rod according to an embodiment of the present invention, and Figure 9 is a perspective view of an assembled plant growth container formed from two panels according to an embodiment of the present invention.
Turning to the drawings, Figure 1 shows generally a panel 10 for use as a side wall of a plant growth container. Panel 10 in the embodiment shown comprises an elongate cuspated sheet 11 having opposed edge sections 12, 13, and a band 14 extending along an upper marginal edge of sheet 11. It can be seen from Figure 2 that sheet 11 has first and second cuspated surfaces 11 a, 11 b which are asymmetrical, although it will be appreciated that the surfaces can in other embodiments be symmetrical.
Band 14 in the embodiments has no cuspations. That has been found to assist in retention of water when the assembled container is initially flooded to promote root growth and in subsequent watering of the plant.
WO 01/35722 PCT/AU00/01389
-II-
Opposed edge sections 12, 13 are non-cuspated. Edge sections 12, 13 in the embodiment shown extend substantially vertically when the panel 10 is in its intended orientation as an upright side wall of a plant growth container.
Edge section 12 comprises a spine having a pair of opposed elongate bands 15, 16 connected by a plurality of spaced apart ribs 17. Recesses 18 are defined by the spaces between spaced apart ribs 17. In similar fashion edge section 13 comprises a spine having a pair of opposed elongate bands 21, 24 connected by a plurality of spaced apart ribs 19.
Recesses 20 are defined by the spaces between spaced apart ribs 19. During assembly edge sections 12, 13, whether carried by the same sheet 11 or by adjacent sheets 11, 31, interleave, interengage or otherwise cooperate when brought together to define a guideway in the form of a channel comprising in the embodiments shown half-circles 22, 23.
The embodiment of Figure 3 shows an alternative edge section arrangement to the spine arrangement of Figure 2, wherein edge sections 12, 13 have complementary engagement portions comprising a ridge and a recess capable of interengaging to define a guideway when half-circles 22, 23 are brought together.
A perforated base 30 for the plant growth container may be provided as shown in Figure 5. Although not clearly shown in that Figure, base 30 is adapted to be received in a recess formed between adjacent substantially horizontal rows of cuspations of sheet 11 or of sheets 11, 31, and held in the recess following assembly of the container. Also, although not shown, base 30 includes a plurality of feet to raise the base 30 above the ground to maintain a distance between the base 30 and the ground.
Figures 6 and 7 illustrate holding means in the form of an elongated rod 32. Rod 32 is insertable in the guideway formed by the registry of edge sections 12, 13. Rod 32 on insertion can be passed along the guideway so formed to releasably hold the edge sections 12, 13 whereby to form a side wall of the container. In a particularly preferred embodiment, movement of the rod 32 along the guideway facilitates a sequential wedge action, that is, the arrangement of the guideway and the rod 32 is such that as the rod 32 passes along the guideway the edge sections 12, 13 are progressively or sequentially drawn together. In this manner, a tauter connection between the edge sections of the same sheet or of adjacent sheets may be effected.
As shown in Figures, rod 32 includes a taper 33, and Figure 9 shows rods 32 having a grip 34 in the form of an element extending transversely to the longitudinal axis of the WO 01/35722 PCT/AU00/01389 -12rod 32. Although not shown in the Figures, rod 32 may include a recess engageable with a rim of the base 30. Engagement of the recess with the rim may be effected by rotation of the rod in the guideway to locate the rim in the recess. This arrangement assists in facilitating a secure connection between edge sections.
Figure 8 illustrates rod 32, which in the embodiment shown is substantially oval in cross-section, in position in the guideway formed by the registry of ribs 18, 19. As can be seen from that Figure, the external cross-sectional dimension of the rod 32 is greater in one direction than the internal cross-sectional dimension of the guideway. Rotation of the rod 32 in the guideway may accordingly have the effect of urging the edge sections 12, 13 toward or away from one another. In this way the distance between edge sections can be adjusted.
The embodiment of Figure 9 illustrates an assembled substantially cylindrical opentopped plant growth container 35 comprising a pair of panels 11, 31 for forming a side wall of the container 35. Each panel 11, 31 comprises an elongate cuspated sheet having apertures (not clearly shown) formed in at least some of the outwardly projecting cusps to facilitate air root pruning of the root structure of a plant (not shown) grown within the container 35. The sheets of panels 11, 31 each include opposed non-cuspated edge sections disposed substantially vertically when the container is in its intended orientation as shown. Each edge section has a spine having a pair of elongate bands connected by a plurality of spaced apart ribs. The spaced apart ribs of the edge sections are capable of interleaving, interengaging or otherwise cooperating with an edge section of similar configuration of an adjacent sheet to form a guideway. When interleaved the edge sections form a guideway for holding means in the form of rod 32. Rod 32 is capable of being inserted in and of passing along the guideway. Rod 32 releasably holds the edge sections whereby to form a side wall of the container 35. Rod 32 is capable of rotation in the guideway to adjust the distance between the interleaved edge sections.
Although not shown in Figure 9, container 35 may include one or more handles.
The handle may be attachable to a panel 11, 31 as described. In an alternative embodiment the handle may be attachable to rod 32. The handle may be pivotable relative to the component to which it is attached. The handle may comprise a loop. The loop may be of sufficient dimension or diameter to fit over at least one cuspation of the sheet of a panel 11, WO 01/35722 PCT/AU00/01389 -13- 31 to provide an additional means of maintaining the structural integrity of the container when assembled.
In use, to assemble a plant growth container 35 as described having a pair of panels for forming a side wall of the container and a base, a pair of panels 11, 31 as described are provided, and a rim of the base 30 positioned in a recess formed between adjacent substantially horizontal rows of cuspations of the panels, the base 30 being held in the recess following assembly of the container 35. The edge sections of the panels are brought together to form a guideway for holding means in the form of rod 32, and rod 32 is passed along the guideway to releasably hold the edge sections together forming a side wall of the container, whereby to form an assembled container 35 as shown. Rod 32 may be rotated in the guideway to adjust the distance between the edge sections.
The container may be easily disassembled by withdrawing rod 32 from the guideway, thereby gaining access to the interior of the container 35. In this manner a tree or other flora may be removed from the container and transplanted.
Following assembly the container may be filled with a growth medium and a seedling or other flora planted in the growth medium.
The word 'comprising' and forms of the word 'comprising' as used in this specification does not limit the invention claimed to exclude any variants or additions.
Modifications and improvements to the invention will be readily apparent to those skilled in the art. Such modifications and improvements are intended to be within the scope of this invention.
