CROSS-REFERENCE TO RELATED APPLICATION  
       [0001]    This application claims priority from US Provisional Application for Patent Serial No. 60/402,082, filed on Aug. 9, 2002. 
     
    
     
       FIELD OF THE INVENTION  
         [0002]    The present invention relates to the general field of horticultural accessories and is more particularly concerned with a plant watering device.  
         BACKGROUND OF THE INVENTION  
         [0003]    There exists a plurality of situations wherein it is desirable to dispense a relatively constant volume of liquid, either continuously or at periodic time intervals. For example, typical applications requiring liquid to be dispensed in a controlled fashion include plant feeding or watering, fertilizing, pet watering, pet medicating, lubricating in general, humidifying and fumigating, air freshening, toilet bowl and drain cleaning, just to name a few.  
           [0004]    Expanding on the plant feeding or watering example, it is well known that house plants are a popular way to create a pleasant and healthy environment. With current trends, such as cocooning and the increased awareness about the impacts of living environments on the health of individuals, plants of various sorts are being used increasingly in various situations and environments such as dwellings, work places and entertainment environments to beautify and enrich the appearance of the area.  
           [0005]    It is also well known that moisture is essential to sustain plant life. In soil, moisture and oxygen are present generally in an inversely proportionate ratio. Accordingly, as the moisture content of the soil increases, the oxygen level decreases. An imbalance between oxygen and water reduces or may even stop photosynthesis. Hence, the maintenance of a proper moisture/oxygen balance optimizes the photosynthetic process for a given plant and, therefore, a plant&#39;s growths, assuming that other essential environmental factors are present.  
           [0006]    If, for example, the percentage of soil moisture is reduced, the plant roots must expend additional energy in order to obtain moisture by osmosis. This, in turn, necessarily diminishes the energy that would otherwise be available for growth. A deprivation of oxygen by overwatering similarly reduces the growth process.  
           [0007]    Plant roots develop randomly and omni-directionally, but survive in any direction only to the extent that moisture is immediately encountered and assimilable. When aridity is encountered, the most efficient finer root endings quickly atrophy. Accordingly, to achieve optimal growth, the majority of container plants require evenness of moisture with regard to both spatial distribution of the moisture and the mean moisture level overtime.  
           [0008]    The conventional method of watering a house plant involves saturating the soil mass. Typically, most house plants will stay 100% moist for a few days after being saturated. Over the following days, the moisture level will most often remain intermediate before becoming semi-arid and then arid. Depending on the attentiveness of the plant owner, this arid condition may continue for a number of additional days, often causing residual damage. Thus, during a typical watering cycle, the plant usually experiences an optimal moisture/oxygen balance during only a small portion of the time.  
           [0009]    Furthermore, it is often found that the entire root system is not exposed to an even distribution of moisture. Rather, it usually encounters a concentration of moisture in the lower region of the plant container. This diminishes the size of the root system upon which the remainder of the plant&#39;s growth depends.  
           [0010]    Optimally, watering should be performed on a regular basis using the correct amount of water at appropriate intervals. This is often not the case. Also, if the plant caretaker is absent for any extended period of time, arrangements must be made for watering. The effort and exactness required for conventionally watering plants has been beyond the ability and focus of many who would otherwise enjoy the proximity and decorative value of plants.  
           [0011]    Several methods and devices have been proposed for attempting to provide adequate watering in the absence of a plant caretaker. One of these methods involves moving the plants to a sink or other basin and sitting the latter in a shallow level of water in order to soak the roots continuously for the entire period of absence. This method is however harmful to plants requiring roots to dry out between waterings. Too much water can also lead to molds that can kill the plant. Furthermore, this method is impractical where the plants are either numerous and/or too big.  
           [0012]    Relatively complex automatic systems using electromechanical timers for actuating a valve at preset intervals for a preset period of time are also known. It is also common to use systems having small apertures or restrictors for dripping water continuously onto the plant. Such systems are typically used in a nursery or a garden where plants are grouped closely together and water can be supplied from a pressurized source. Such systems, however, may prove to be impractical or undesirable for a typical home where plants are spread out or moved randomly. Furthermore, these types of systems are both relatively complex and expensive.  
           [0013]    Gravity feeding from elevated reservoirs is sometimes used but this method also includes interconnecting various tubings and is therefore impractical for most watering requirements in an office or a home.  
           [0014]    Another method for automatically watering plants involves the use of a wick. A container of water is positioned adjacent to or above the plant and a wetted wick is extended from the container to the plant. Capillary action draws water gradually from the container to the plant. This method, however, suffers from numerous drawbacks. Indeed, while it may provide for a generally continuous flow, the rate of flow varies with the level of water in the container. As the level drops, the flow rate slows accordingly. Furthermore, it is very difficult to customize the flow rate for a given application since the flow rate is directly proportional to the capillary action which, in turn, is directly proportional to the level of water in the feeding container.  
           [0015]    Other drawbacks associated with prior automatic liquid dispensing systems using a capillary action include the poor reliability of such systems which are subject to malfunction due to clogging. Also, most prior art systems using capillary action are not well suited for providing irrigation to the plant using liquids having physical properties other than those of water such as liquid fertilizers, growth enhancers and the like.  
           [0016]    Furthermore, some prior art systems do not allow for dispensing of liquids for extended periods of time using relatively small and aesthetically pleasing dispensing containers. Also, some prior art devices lend themselves to important water losses through evaporation and other types of water losses through poor design choices.  
           [0017]    Still furthermore, some prior art devices suffer from being overly complex and from requiring relatively complex maneuvers on behalf of the intended user. Still furthermore, most prior art devices suffer from being unaesthetic and, hence, defeating the purpose of attempting to improve the overall appearance of an area by providing plants. Accordingly, there exists a need for an improved plant watering device.  
         SUMMARY OF THE INVENTION  
         [0018]    Advantages of the present invention include the fact that the proposed plant watering device is capable of automatically supplying proper amounts of liquids into the soil of a flower pot for growing a plant. The proposed device allows for the dispensing of a relatively constant volume of liquid throughout a preset dispensing period. Also, the proposed device allows for the customization of the amount of liquid to be dispensed over a predetermined period of time.  
           [0019]    Furthermore, the proposed device provides several horticultural advantages including a reduction in the watering frequency. Also, the elimination of overhead watering prevents pesticides and other useful products from being washed off the leaves of the plant increasing their effective half-life. Furthermore, the proposed method improves the retention of nutrients in the soil. Also, due to the inverted leaching, certain compounds such as salt which are harmful to the plant when concentrated near roots will steadily move out of the primary root zone as fresh water is dripped at specific locations in the reservoir. Still furthermore, the proposed type of watering creates a beneficial environment for the plant by increasing the humidity level around the plant&#39;s foliage.  
           [0020]    The proposed watering device allows for water to be delivered at a predetermined rate and at specific predetermined locations in the soil. This allows the device to target specific moisturizing areas.  
           [0021]    Also, the proposed device allows for dispensing of various types of liquids having different physical characteristics including water, fertilizers, growth enhancers and delayers and mixtures of such products with reduced risks of modifying the dispensing rate.  
           [0022]    Furthermore, the proposed device is designed to reduce the risk of blockage or clogging of its dispensing components by having the latter contact the soil. Still furthermore, the proposed device is designed so as to be installable in a conventional flower pot in a stable manner.  
           [0023]    Also, the proposed device is designed so as to allow an intended user to initiate the irrigation process through a set of quick, easy and ergonomical steps without requiring special tooling or manual dexterity.  
           [0024]    Still furthermore, the proposed device is designed so as to reduce the risks of splashing and spillage of water during both installation and removal of the device into and from the flower pot and during other steps required for initiating and/or terminating the watering operation.  
           [0025]    Also, the proposed device is specifically designed so as to provide an aesthetically pleasing visual appearance so as to reduce the risks of deterring the overall aesthetical aspect of the plant and its immediate environment. Still furthermore, the proposed device is designed so as to be manufactured using conventional forms of manufacturing so as to realize a watering system that will be economically feasible, long-lasting and relatively trouble-free in operation.  
           [0026]    In accordance with an embodiment of the present invention, there is provided a plant watering device for use in a growing medium, the device comprising: a base having an open top liquid receiving section with a discharge inlet aperture located therein; a medium engaging section connected to the base and having a discharge outlet aperture in communication with the discharge inlet aperture; a container having a discharge spout, the container having an amount of a liquid contained therein, the container being fittingly mounted on the base, the discharge spout being positioned into the liquid receiving section; and at least one wick component mounted in the liquid receiver section to receive the liquid from the container and extending between the discharge inlet aperture and the discharge outlet aperture to automatically deliver the liquid to the discharge outlet aperture and into the growth medium at a controlled rate.

The wick retaining member and the liquid blocking member both include a pair of inner wall complexes extending integrally from an inner surface of the peripheral sidewall and the base wall.  
           [0036]    Typically, each inner wall complex further includes a pair of spaced apart and generally rectilinear wick abutment sections extending integrally and generally perpendicularly from the inner surface of the peripheral sidewall. The wick abutment sections extend into a generally U-shaped blocking segment and include a pair of blocking and abutment flanges, the wick abutment sections and the blocking segments substantially encircle the dispensing inlet aperture.  
           [0037]    Conveniently, a centering component extends generally perpendicularly from the base wall. The centering component includes four centering blades arranged in a cross-shaped configuration and tapered into a pointed apex. Typically, the base wall further includes a plurality of recesses extending radially outwardly from the centering component.  
           [0038]    Typically, the aforesaid device includes two wick components. Each wick component includes a generally elongate main segment, a pair of generally elongate auxiliary segments and a spacing segment, the main segment and the auxiliary segments extending in a generally parallel and spaced apart relationship relative to each other, the auxiliary segments being positioned laterally on opposite sides of the main segment and define a pair of segment clearance spacings therebetween, the auxiliary segments each having a distal tip.  
           [0039]    Typically, the main segment extends through the dispensing inlet aperture into the dispensing channel, the auxiliary segments extending into the liquid receiving section, the distal tips being located adjacent the base wall. Typically, the wick components include at least one micro-channel formed therein. Typically, the wick component is made from a hydrophilic material.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0053]    Referring to FIG. 10, there is shown a plant watering device  10 , in accordance with an embodiment of the present invention. The plant watering device  10  is shown about to be used for watering a plant  12  growing in a growing medium  14  contained within a conventional flower pot or container  16 . Although the device  10  is shown as being used with a conventional frustro-conical plant container  16 , and with a specific variety of plant  12 , it should be understood that the device  10  could be used with any suitable plant container for any suitable type of plant without departing from the scope of the present invention.  
         [0054]    Also, the term “growing medium” should be construed as any suitable growing material such as soil, earth, earth mixed with peat moss, fertilizers or other growth enhancing products, or any suitable material without departing from the scope of the present invention. The device  10  is used for providing a suitable liquid to the root system of the plant  12 . Again, the term “liquid” should be construed as including water, liquid fertilizers, liquid nutrients, liquid growth regulators and enhancers, a mixture of the above or any other suitable liquid without departing from the scope of the present invention.  
         [0055]    Furthermore, although the present invention is exemplified as being used specifically in a context of plant watering, it should be understood that some or all of the characteristics of the present invention could be used in other liquid dispensing situations including pet watering, medicating, humidifying and fumigating, toilet bowl and drain cleaning, air freshening, fertilizing and like without departing from the scope of the present invention.  
         [0056]    Referring now more specifically to FIG. 1, there is shown that the device  10  generally includes a container component  18  for containing the liquid to be dispensed. The device  10  also includes a base component  20  for anchoring the device  10  into the growing medium  14  and for delivering the liquid to at least one specific location within the growing medium  14 . The device  10  further includes at least one and preferably two wick components  22  for regulating the dispensing flow.  
         [0057]    More specifically, the base component  20  typically includes a liquid receiving section  24  and a growth medium engaging section  26 . The liquid receiving section  24  typically defines an open-top receptacle having a receptacle base wall  28  and a receptacle peripheral wall or sidewall  30 .  
         [0058]    The receptacle peripheral sidewall  30  is typically provided with a peripheral wall flange  32  extending generally radially and outwardly from an upper peripheral edge thereof. It should be understood that although the liquid-receiving section  24  is illustrated throughout the figures as having a generally cylindrical configuration, it could have other open-top configurations without departing from the scope of the present invention.  
         [0059]    The ground engaging section  26  includes at least one, and preferably two anchoring pegs  34  extending from the liquid-receiving section  24  in a direction leading generally away from the receptacle base wall  28 . Preferably, the anchoring pegs  34  extend generally integrally from generally diametrically opposed sections of the receptacle peripheral wall  30  so as to define a peg spacing  36  therebetween.  
         [0060]    The peg spacing  36  is intended to improve stability of the anchorage provided by the anchoring pegs  34 . Furthermore, the anchoring pegs  34  may optionally diverge away from each other in a direction leading away from the liquid-receiving section  24 .  
         [0061]    Each anchoring peg  34  is provided with a dispensing or discharge channel  38  extending at least partially therealong between a corresponding dispensing inlet aperture  40  formed in the receptacle base wall  28  and a corresponding dispensing or discharge outlet  42  formed in the anchoring peg  34  typically intermediate its longitudinal ends.  
         [0062]    In one embodiment of the invention shown in FIGS. 1 through 3,  5  and  7  through  10 , the dispensing outlet  42  includes a dispensing slot  44  extending at least partially along an inner surface of each anchoring peg  34 . In an alternative embodiment of the invention shown in FIGS. 4 and 6, the dispensing outlet  42  includes a generally disc-shaped dispensing aperture  44 ′ formed on an outer surface of each anchoring peg  34 .  
         [0063]    It should be understood that the dispensing outlet  42  could take any suitable configuration and could be positioned anywhere along either one or both of the anchoring pegs  34  without departing from the scope of the present invention.  
         [0064]    Each anchoring peg  34  preferably has a generally tapering configuration in a direction leading away from the liquid-receiving section  24 . Each anchoring peg  34  hence typically defines a generally pointed distal tip  46 . The tapering configuration defining a generally pointed tip is adapted to facilitate insertion of the anchoring pegs  34  into the growing medium  14 .  
         [0065]    In the embodiment of the invention shown in FIGS. 4 and 6, each anchoring peg  34  is preferably provided with a contamination-prevention means for preventing contamination of the dispensing aperture  44 ′ by the growing medium once the corresponding anchoring peg  34  is inserted therein. Typically, the contamination-preventing means includes a channel-forming section  48  protruding inwardly from the inner surface of the corresponding anchoring legs  34  in a direction generally perpendicular to the longitudinal axis of the corresponding anchoring pegs  34 .  
         [0066]    The channel-forming section  48  is intended to compact the growing medium  14  located immediately adjacent to the dispensing aperture  44 ′ when the anchoring pegs  34  are being inserted into the growing medium  14 . By compacting the growing medium  14 , the channel-forming section  48  create a clearance  50  between the dispensing aperture  44 ′ and the peripheral wall of the adjacent channel so as to reduce the risks of having the growing medium  14  clog or otherwise block the dispensing aperture  44 ′. The clearance  50  also prevents growing medium positioned adjacent the dispensing aperture  44 ′ from generating a counter-effective capillary action in the channel  38 .  
         [0067]    The clearance or spacing  50  is further increased by forming the dispensing aperture  44 ′ on an inwardly tapered cut-out surface  52  of the anchoring pegs  34 . Furthermore, a raking ledge  54  is formed on each anchoring peg  34  adjacent the dispensing aperture  44 ′ so as to further reduce the risks of having growing medium penetrate into or be in the immediate vicinity of the dispensing aperture  44 ′.  
         [0068]    The liquid receiving section  24  is further provided with a wick-retaining member for retaining the wick component  22  in a predetermined spatial relationship relative to the dispensing inlet aperture  40  and corresponding dispensing or discharge channel  38 . The liquid-receiving section  24  is still further typically provided with a liquid-blocking member formed therein for preventing liquid contained within the liquid-receiving section  24  from flowing directly into the dispensing inlet aperture  40 . The wick component  22  extends between the liquid receiving section  24  and the discharge channel  38 .  
         [0069]    Typically, both the wick-retaining member and the liquid-blocking member include a pair or generally similar inner wall complexes  56 , both extending integrally from the inner surfaces of the receptacle peripheral and base walls  30 ,  28 . Each inner wall complex  56  typically includes a pair or spaced-apart and generally rectilinear wick abutment sections  58  extending integrally in substantially perpendicularly from the inner surface of the receptacle peripheral wall  30 .  
         [0070]    The wick-abutment sections  58  extend integrally into a generally U-shaped blocking segment  60 . A pair of blocking and abutment flanges  62  extend outwardly and generally perpendicularly at the intersection of the wick-abutment and blocking segments  58 ,  60 . The wick-abutment and blocking segments  58 ,  60  are adapted to substantially encircle the dispensing inlet aperture  40  so as to prevent liquid contained within the liquid-receiving section  24  from flowing directly thereinto.  
         [0071]    As illustrated more specifically in FIG. 5, each wick component  22  typically has a generally T-shaped configuration defining a generally elongated main segment  64 , a pair of generally elongated auxiliary segments  66  and a wick spacing segment  68  extending therebetween. The main and auxiliary segments  64 ,  66  typically extend in a generally parallel and spaced-apart relationship relative to each other with the auxiliary segments  66  positioned laterally on opposite sides of the main segment  64  so as to define a pair of segment clearance spacings  70  therebetween.  
         [0072]    The main, auxiliary and spacing segments  64 ,  66 , and  68  are configured and sized so that when the wick component  22  is in its operational configuration shown in FIG. 5, the main segment  64  extends through the dispensing inlet aperture  40  into the dispensing channel  38  with the auxiliary segments  66  extending into the liquid-receiving section  24  with their distal tip generally adjacent the receptacle base wall  30 .  
         [0073]    The wick component  22  is secured into its operational configuration by having the wick clearance spacings  70  overriding the wick abutment sections  58  and the auxiliary segments  66  sandwiched between the inner surface of the receptacle peripheral wall  30  and an opposed surface of the blocking and abutment flanges  62 .  
         [0074]    Typically, both the blocking segments  60  and the blocking and abutment flanges  62  extend from the receptacle base wall  28  to a position substantially in register with the upper peripheral edge of the spacing segments  68  when the wick component  22  is in its operational configuration. Hence, each combination of a wick component  22 , a corresponding blocking segment  60  and a corresponding blocking and abutment flanges  62  form a blocking structure for preventing water from flowing directly into the dispensing inlet aperture  40 . The height of the blocking structure prevents water from being drawn into the dispensing inlet aperture  40  even when the liquid-receiving section  24  is substantially tilted.  
         [0075]    The wick component  22  is typically manufactured so as to form micro-channels therein, typically at least one microchannel. Typically, each wick component  22  is formed using a hydrophilic material such as a suitable thermoplastic polymeric resin in powderous form blown into a mold. The mold is heated to a suitable temperature so as to allow for the powderous polymeric resin to agglomerate and to form channels. As opposed to expanded or spongious polymeric components, the wick components  22  preferably form a limited number and ideally no closed cells. The micro-channels are adapted to facilitate both capillary and gravitational flow of liquid therein. In at least one embodiment of the invention, the wick components  22  are made out of cotton coated with an hydrophilic polymeric material such as nylon.  
         [0076]    As illustrated more specifically in FIG. 5, once the auxiliary segments  66  are dipped into a liquid  72  contained within the receptacle  24 , the micro-channels of the wick component  22  are able to draw the liquid  72  upwardly by capillarity from the tip of the auxiliary segments  66  towards the spacing segments  68 . As is well known, the capillary action is a phenomenon caused by the adhesion of the liquid molecules to a given surface due to surface tension. Hence, the micro-channels are typically calibrated so as to optimize the capillary action.  
         [0077]    Once the liquid  72  has reached the spacing segment  68 , the liquid  72  drops into the main segment  64  through the action of gravity. Each wick component  22  is configured and sized so as to provide a customized flow rate flowing thereacross between the auxiliary and main segments  66 ,  64 . In at least one embodiment of the invention, in order to prevent adhesion forces and other phenomenon from restricting the flow of liquid  72  in the main segment  64 , the intermediate segment  68  has an intermediate segment width  74  greater than the main segment width  76  and the auxiliary segment width  78 . This allows for accumulation of fluid into the spacing segments  68 , increasing the hydrostatic pressure of the liquid in the wick main segment  64 , and, hence, the gravitational pressure favoring the downward flow in the main channel  64 .  
         [0078]    Optionally, each wick component  22  could be configured and sized for providing a given flow rate customized for given watering parameters such as the type of plant, the relative humidity of the growing environment and so forth. Also, optionally, each wick component  22  could be embedded with a releasable physical agents such as fertilizers or the like adapted to be released at a predetermined rate by the wick component  22  mixed with the liquid as the latter flows therethrough.  
         [0079]    Each liquid receiving section  24  is preferably further provided with a centering component  80  extending generally perpendicularly relative to the receptacle base wall  28  in a substantially central relationship relative thereto. The centering component  80  typically includes at least one and preferably four centering blades  82  having a generally cross-shaped configuration and tapering into a generally pointed apex  84 .  
         [0080]    The centering component  80  is intended to facilitate centering of the container component  18  when the latter is mounted to the liquid-receiving section  24 . Also, the centering component  80 , with its tapering configuration, is intended to gradually break the surface tension at the air-liquid interface of the water contained in the container component  18  when the latter is tilted thereover. This, in turn, is intended to prevent or reduce the risks of spillage of the content of the container component  18  when the latter is attached to the base component  20 .  
         [0081]    The receptacle base wall  28  is preferably provided with recesses  86  formed therein for providing an interrupted surface so as to reduce the risks of creating a surface tension vacuum when the container and base components  18 ,  20  are assembled. The recesses  86  are also adapted to facilitate the flow of the liquid within the receptacle liquid-receiving section  24  towards the auxiliary segments  66 . The recesses  86  typically form a generally radial pattern which extends from the centering component  80 , as illustrated more specifically in FIG. 3.  
         [0082]    Referring now more specifically to FIGS. 1, 2 and  8  through  10 , there is shown in greater details some of the features of the container component  18 . The container component  18  defines a liquid containing section or enclosure  88  for containing a suitable amount of liquid. The liquid-containing section  88  extends into a stabilizing flange  89  leading to a discharge or dispensing spout  90 . The stabilizing flange  89  typically has a disc-shaped configuration and is configured in size so as to be generally fittingly insertable into the open top of the liquid-receiving section  24 .  
         [0083]    The liquid-receiving section  88  typically defines a generally flat abutment segment  92  for being abuttingly rested or seated against the upper surface of the receptacle flange  32 . The spout  90  typically has a generally cylindrical configuration and is typically configured in size so as to be substantially fittingly insertable over the centering component  80 .  
         [0084]    The liquid containing section  88  may take any suitable configuration. In the embodiments shown throughout the figures, the liquid-containing section  88  is formed out of a generally transparent or translucent and colored material and has the general configuration of a stylized frog. It should be understood that the liquid-receiving section  88  could have any suitable configurations without departing from the scope of the present invention. Typically, the liquid-receiving section  88  has an aesthetically pleasing appearance and is designed so as to be handled ergonomically.  
         [0085]    In use, as illustrated in FIG. 7, each wick component  22  is initially installed ergonomically into its operational configuration by grasping the spacing segments  68  and sliding the wick component  22  towards the inner wall complex  56 . The auxiliary segments  66  are inserted between the blade and abutment flanges  62  and the inner surface of the receptacle peripheral wall  30 . The main segment  64  is inserted into the dispensing channel  38 .  
         [0086]    As illustrated in FIGS. 8 and 9, the container component  18  is then filled with a liquid such as water. Again, the configuration of the liquid-containing section  88  facilitates ergonomical handling of the container component  18  such as for centering the spout  90  under a conventional faucet  94 . The base component  20  is then mounted over the inverted container component  18  with the centering component  80  penetrating the channel formed by the spout  90 , to attain a discharge configuration.  
         [0087]    As illustrated in FIG. 10, once the base and container components  20 ,  18  are assembled together, the device  10  is anchored into the growing medium  14  by having the anchoring pegs  34  penetrate the growing medium  14  at a predetermined suitable location. Typically, the liquid being enclosed within the device  10 , evaporation of the liquid is reduced and the container component  18 , together with the wick component  22  are calibrated so that the device  10  will dispense approximately 500 ml over a period of a week. It should be understood that the device  10  could dispense any other suitable amount of liquid at any suitable rate without departing from the scope of the present invention.
