DETAILED DESCRIPTION OF EMBODIMENTS

[0112] Attention is first directed to FIG. 1 of the drawings, illustrating a pot system according to an example of the present disclosure, generally designated 20, comprising a pot housing generally designated 22 accommodating a pot liner 24 received within the pot housing 22, and a plant 26 planted in the growing media 28 (soil) within the pot liner 24.

[0113] The pot housing 22 (best seen in FIG. 2A and in sectioned view of FIG. 2B) is a tubular, round vessel, being liquid impermeable (made of liquid impermeable material e.g., porcelain, glass, plastic, metal, etc.), and/or coated with a liquid impermeable layer for improving impermeability thereof. Alternatively, the pot housing can be made of wood, composite materials etc., adjusted as needed to prevent liquid permeability. The pot housing 22 has a base with an inside bottom surface 32, and a bottom surface 34 for placing on a surface, and side wall 38 extending from the base 30 and ending at a pot housing top edge 40. Side wall 38 has an inside surface 42 and in the present example the side wall 38 slightly tapers upwardly. The shape and size of the inside section of the pot housing 22 can vary, however having a nominal size, to which the size of pot liner 24 corresponds, at least as far as the top edge size of the pot housing.

[0114] Turning now to FIG. 3, reference is made to the pot liner 24, which as mentioned hereinabove, is designated a nominal size corresponding to the pot housing 22, such that at an assembled position (FIGS. 1 and 2) the pot liner 24 is fully received within the pot housing 22.

[0115] The pot liner 24 is made of a liquid impermeable material, and has no openings, except near a top edge thereof, as will be discussed hereinafter. The pot liner 24 is made of a rigid though pliable material, so that it can be deformed upon applying external force thereto, however, will assume its original shape upon ceasing said external force.

[0116] The pot liner 24 has a general frustoconical shape, with a base 44 and a perimetric side wall 46 however with a longitudinal inward shaped depression 48 extending along the side wall 46. Once placed within the pot housing 22, the depressed/indented portion 48 serves as a filling duct for filling irrigation liquid into an irrigation liquid reservoir and for accommodating a liquid level indicator, to be discussed. A plant/planting space 49 is defined by the perimetric side wall 46 upwardly extending between the base 44 and a top edge/rim 50 of the pot liner 24.

[0117] The top edge 50 of the pot liner, at the vicinity of the indented portion 48, is configured with a retention member 52, said retention member can be integral with the pot liner 24 (as in the example of FIGS. 5A-5C), or it can be applied thereto (as per retention member 52 in FIGS. 11A to 11D). The retention member 52 is made of stiff material whereby applying a force thereto results in deformation of the pot liner 24. In particular, as illustrated in FIGS. 6A and 6B, applying radially inward directed force, in direction of arrow F (by user's finger 60) the pot liner deforms, at least at a top portion thereof. The retention member 52 is a crescent-shaped element, complimentary to the top edge 50 of the pot liner 24, though disposed at an opposite orientation, and configured with two end platelets 55 each having an end edge 57.

[0118] The arrangement being such that flexibility of the pot liner 24 facilitates easy insertion into a pot housing, and once in place the top edge 50 of the pot liner snugly bears against an inside top surface portion of the pot housing (FIG. 7D). This is exemplified in sequential images of FIGS. 7A to 7D. In FIG. 7A the pot liner 24 is freely placed within the pot housing 22 (wherein the top portion of the pot liner rests over the top edge 40 of the pot housing 22). Then, radial inward force F is applied by user's finger 60, in direction of arrow F (FIGS. 7B and 7C) resulting in deformation of the pot liner, namely restricting the circumscribing circle at least at the top portion thereof, such that it is fully positioned within the pot housing (FIG. 7D), namely with a top edge 50 of the pot liner disposed below a top edge 40 of the of housing 22.

[0119] As seen, best in FIGS. 15 and 16, at the assembled position the end edges 57 of end platelets 55 bare against the inside wall surface 42 of the pot housing 22, providing support and sealing the deformed end portions 59 of the top edge 50 against the inside wall surface 42 of the pot housing 22.

[0120] As mentioned hereinbefore, the entire body of the pot liner 24 is liquid impermeable, and however comprises one or more capillary assembly holders, disposed below the top edge 50, and configured for passing therethrough a tubular capillary assembly (to be discussed hereinafter in detail). A capillary assembly holder according to an example of the disclosure is designated 70 (shown in detail in FIGS. 4A and 4B), and comprises an opening 72 below the top edge 50, the opening extending at a side wall of the pot liner with an axial orientation extending perpendicular to a longitudinal axis of the pot liner 24. The capillary assembly holder 70 further comprises a tubular section segment 74 radially disposed and inwardly extending from the side wall 46. The opening 72 is formed so as to give rise to a path extending such that a capillary assembly generally designated 100 (discussed in greater detail hereinafter) is forced to bend at an acute angle from the outside of the pot liner into the space 49. Thereby, a tubular capillary assembly member can be held by the external channel 78 formed by the tubular section. The arrangement is such, as will be exemplified hereinbelow, that a tubular capillary assembly can extend from an outside of the pot liner 24, through opening 72 and into the plant space 49 of the pot liner 24. It can be seen that the pot liner 24 of the example shown in FIG. 3 comprises a single capillary assembly holder 70, whereas the pot liner 24 of the example shown in FIGS. 5A to 5C comprises three capillary assembly holders 70, by way of example.

[0121] An irrigation liquid reservoir extends between inside wall surfaces of the pot housing (namely inside bottom surface 32 and inside wall surface 42) and outside surfaces of the pot liner 24 (namely base surface 44 and side wall 46). It is appreciated that an assembled position of the pot system, the base surface 44 of the pot liner can reach the inside bottom surface 32 or extend spaced therefrom, however with a sufficient liquid reservoir extending between the depressed portion 48 of the pot liner 24 and the inside wall surface 42 of the pot housing 22, defining a well-like irrigation reservoir 47 (FIGS. 2A, 2B, 9D, 9E, 16). As will be explained hereinafter, said well-like irrigation reservoir can accommodate a liquid level indicator.

[0122] Another example a of capillary assembly holder 80 is illustrated in FIGS. 13A to 13D, said capillary assembly holder 80 comprises an opening extending through the side wall 46 of the pot liner 24, with a path extending such that the capillary assembly generally designated 100 (discussed in greater detail hereinafter) is forced to bend at an acute angle from the outside of the pot liner into the space 49. Further noted, an outside portion of the capillary assembly holder 80 is configured with two wing-like members 84 (best seen in FIG. 13B), configured for arresting an outside portion 102 of the capillary assembly 100.

[0123] Yet an example of a capillary assembly holder is illustrated in Figs in FIGS. 14A to 14C. The capillary assembly holder generally designated 90 simply comprises a cut 92 at the side wall 46 of the pot liner, right below the top edge 50, with an inward indented portion 94.

[0124] A simplified example of a capillary assembly holder (not shown) is a mere indent at the top edge of the pot liner, with or without a capillary assembly fastener disposed at either one or both the outside surface of the inside surface of the pot liner.

[0125] It is further appreciated. as illustrated in FIG. 8, that the pot liner 24 is shaped such that it can be nestable stacked within like pot liners 24.sub.i-24.sub.n.

[0126] Turning now to FIGS. 11A to 11D there is illustrated an example wherein the retention member 52 is detachably attachable over the top edge 50 of a pot liner 24 (not integral with the retention member 52), wherein the retention member 52 is curved in register with the curvature of the top portion of the pot liner, and comprises a slot 61 extending between an inside clamping wall 63.sub.in and an outside clamping wall 63.sub.out, with a top shoulder 65 extending between platelets 55 and end edges 57, as discussed above. The arrangement is such that the retention member 52 can be applied over the top edge 50 of the pot liner, such that prior to assembly (FIG. 11C) it does not interfere with nesting-stacking of like pot liners. However, when assembled, as in FIG. 11D, the retention member 52 serves as discussed hereinabove as in connection with other examples and wherein the retention member 52 is inclined such that the top shoulder 65 extends substantially coplanar with the top edge 50 of the pot liner 24.

[0127] Further attention is now directed to FIGS. 9A to 9C of the drawings, directed to a subassembly of a retention member associated with an irrigation liquid level indicator, generally designated 125. The subassembly 125 comprises a retention member 126 configured as a detachable-attachable element, configured for mounting over a top edge of pot liner, as discussed hereinbefore in connection with FIGS. 11A to 11C, though it is appreciated that the subassembly 125 can just as well be integral with the pot liner. Whilst the retention member 126 is substantially similar with that disclosed in connection with FIGS. 11A and 11B, however it is further configured with an automatic liquid level indicator. The liquid level indicator generally designated 128 comprises a lid pivotally articulated at hinges 134 to the retention member 126, said lid having a shape complimentary of the indented portion of the liner. The lid 130 is pivotal between an open position (FIG. 9c) and a normally closed position (FIG. 9B), where at the closed position the lid extends substantially coplanar with the retention member 126 and as such, at this position, it covers the opening of the irrigation liquid filling duct (closed in FIG. 15; open in FIG. 16).

[0128] The liquid level indicator 128 further comprises a buoy 134 suspended by cord 136 from a rear portion of the lid 130, i.e., behind the lid hinges 134. The cord 136 passes through a guiding port 138 (FIG. 9C) for confirming that the buoy 134 is freely displaceable within the well-like irrigation reservoir 47, and is sufficiently remote from the wall of the indented portion of the line, for avoiding friction therewith. The length of cord 136 is defined such that the lid 130 remains at the closed position as long as the buoy 134 does not drop below a minimal predetermined level within the irrigation liquid reservoir. Once liquid level within the reservoir drops below said minimal predetermined level, the buoy 134 displaces under gravity in direction of arrow 138 (FIG. 9C) and causing the lid 130 to displace into its open position (FIGS. 9A and 9C), said open lid serving as a visible indicator the refiling irrigation liquid is required, and also opens the irrigation liquid reservoir 47 for filling. It is appreciated that the bottom surface of the lid can be colored with an eye-attracting color. Accordingly, it is apparent that the lid 130 remains closed and will open only for filling the liquid reservoir 47 (as shown in FIG. 9E), thus minimizing liquid evaporation from the reservoir.

[0129] As an alternative to the liquid level indicator 128 configured with lid 130, the irrigation liquid reservoir 47 can be closed by a manually removable lid 150 (FIGS. 10A and 10B), said lid 150 comprising a closure portion 152 having a shape complimentary of the indented portion of the liner and configured for bearing over a shoulder of the retention member 52, and supporting stem portion 154 configured for bearing against the wall surface of the indented portion 94 of pot liner 24. When in position the top surface 156 of lid 150 is substantially flush with the top edge 50 of the pot liner 24 (and said surface can serve as an advertising surface).

[0130] Turning now to FIGS. 12A to 12C reference is made to the capillary assembly generally designated 100, also seen in FIGS. 13 and 14. The capillary assembly 100 comprises a capillary media, which in the illustrated example is a multiple strand woven wick 106 and it is appreciated that the capillary media can be made of any sort of material, either organic or inorganic, uniform or not, comprising one or more strands, interwoven or not, and combinations thereof. The wick 106 is received within a liquid impermeable sheath 108 configured with a first (outside) portion 102 and a second (inside) portion 104, with an intermediate foldable portion 106, which in the illustrated example is a bellows-type foldable section. The purpose of the foldable portion is to ensure that at the event of folding the capillary assembly 100, even at an acute angle and even at 180?, a lumen of the sheath 108 remains open, so as to ensure free capillary liquid flow along the wick 106.

[0131] In use (FIGS. 2B and 9D), the capillary assembly 100 is positioned such that a first end 112 of the capillary wick 106 projects from the first (outside) portion 102 of the sheath 108, and a second end 114 of the capillary wick 106 projects from the second (inside) portion 102 of the sheath 108, wherein first end 112 of the capillary wick 106 is immersed at a bottom portion of the liquid reservoir 47, and second end 114 of the capillary wick 106 is disposed within the growing media 28 (soil) at the vicinity of a root base of a plant within the pot liner 24.

[0132] This arrangement, on the one hand, ensures that the plant receives ideal amount of irrigation as it may require and not more than necessary, and, on the other hand, substantially no evaporation takes place from the wick and from the reservoir.

[0133] Turning now to FIGS. 17A and 17B there are illustrated an embodiment of pot liners according to an example of the present disclosure, generally designated 120, nesting received within one another.

[0134] The pot liner differs from the pot liner of the previous example in several aspects. For example, the indented portion 222 is configured with an array of reinforcing ribs 228 for reinforcing the indented portion 222 on the one hand, and on the other hand, reinforcing articulation of the retention member 230.

[0135] Also noticed, the pot liner 220 is configured with one or more nesting stoppers/stacking ribs 234 radially projecting inwardly from an inside surface 236 of the pot liner 220, at a bottom portion thereof. At a bottom, outside portion of the pot liner 220 there are configured corresponding one or more nesting stopper indentions 238, wherein at a nested stacked/nested position the nesting stopper indentions 238 bear over a top edge 240 of the stacking ribs 234 (FIG. 17B). Accordingly, at the nested stacked/nested position the retention member 230 do not engage with one another, thereby preventing their deformation.

[0136] Further seen, in FIGS. 17A and 17C, the capillary assembly holder 244 is configured in the form of an indention 246 at the top edge of the pot liner 220 with two flaps facing each other, extending over said indention 246, whereby there is no need to thread a capillary assembly 250, but rather it can be simply snapingly engaged within the capillary assembly holder 244.

[0137] At an assembled position, when the pot liner is functionally received within the pot housing, there may reside forces on the pot liner, which may act in direction so as to pop-up the pot liner from the pot housing. Such forces can be a result of resiliency of the pot liner and the deformation applied to the pot liner when within the pot housing, as well as buoyancy forces of irrigation liquid within the pot housing. Accordingly, there are several solutions configured to prevent spontaneous pop-up of the pot liner.

[0138] In FIGS. 18A and 18B there is illustrated a pot housing 260 according to an example of the disclosure, wherein at a top portion 262 there is an annular lip 264, facing inwardly, and having a diameter D.sub.H smaller than the maximum (top) diameter D.sub.L of the pot liner 270 (which in the example substantially corresponds with an inside diameter of the pot housing 260. The arrangement is such that at the assembled position the top edge 272 of the pot liner 270 bears under the annular lip 264 and against the inside wall surface 265 of the pot housing 260, wherein the pot liner 286 is barred from spontaneous pop-out from the pot housing.

[0139] In FIG. 18C there is illustrated a different example, wherein the pot housing 180 has a dome-shape section, with a top opening 182 having diameter D.sub.O smaller than a diameter D.sub.I and a top portion of the pot housing 180 below said opening 182, and wherein said diameter D.sub.O is smaller than the diameter maximum (top) diameter D.sub.L of the pot liner 186. The arrangement is such that at the assembled position the top edge 188 of the pot liner 186 bears against the inside wall surface 185 of the pot housing 180, below the opening 182, wherein the pot liner 186 is barred from spontaneous pop-out from the pot housing.

[0140] Any one of the following solutions, can be configured between the pot liner and the pot housing, for preventing spontaneous pop-up of the pot liner from the pot hosing: [0141] a top rim of the pot liner is configured for biased bearing against an inward wall surface of the pot housing, below a top edge of the said pot housing; [0142] the top pot liner rim can have a diameter greater than a diameter of top edge of the pot housing; [0143] the pot housing can be configured at a top portion thereof with an inward projecting pot liner arresting arrangement, for prevent spontaneous pop-up of the pot liner; [0144] the pot liner arresting arrangement can be an inward projection having a diameter suited for arresting a top rim of the pot liner; [0145] the inward projection can be an annular rim or a series of projections; [0146] the pot housing can have a dome-shape, with a top opening thereof having a narrower diameter with respect a lower body portion thereof; [0147] the pot liner can be adhered within the pot housing.
