     BACKGROUND OF THE INVENTION 
       [0007]    1. Field of the Invention 
         [0008]    This invention relates generally to devices for the elimination of human urine while outdoors and specifically outdoor urinal systems that minimize urine scent. 
         [0009]    2. Description of Related Art 
         [0010]    Hunters, photographers and videographers commonly use tree stands or elevated hunting blinds as a vantage point from which to view and hunt game. The nature of these activities requires patience, quiet and concealment by the operator, in order to avoid scaring away the game. Hunters go to extremes to ensure their concealment, including camouflaging themselves and the hunting blind, spraying clothing down with scent retardant, and attempting to be quiet and still. Often they must spend many hours in this low profile state, either on the ground or elevated, in order to view or take aim at their game. 
         [0011]    One of the constant frustrations with the aforementioned activities is the inability to use the bathroom. Leaving the tree stand, hunting blind, elevated platform or even ground level area to urinate on the ground invokes multiple problems. The noise and activity associated with climbing up and down, walking to a desired spot and commencing urination can, of itself, scare nearby animals away. The strong scent associated with human urine is yet another strong animal deterrent. The scent can carry a significant distance and can linger for many days, effectively destroying the concealment of the hunter and often scaring off the prey. 
         [0012]    Frequently, these outdoor pursuits involve long hours and weather that is inclemently cold or hot. Such conditions invite the need for beverages. Many hunters unfortunately, must deign to drink anything at all, in order to avoid the disruption that the need to urinate causes. 
         [0013]    Various methods to solve the problems associated with urination during hunting have been attempted; however none have effectively solved all the problems. The primary problems are the noise and activity associated with having to leave the camouflaged area to urinate on the ground; the odor associated with urinating on the ground or in a device, and the disposal of the urine. 
         [0014]    A few patents and marketed products for this problem exist yet none offer a true scent minimization system. Few hunters wish to urinate in a bottle or packet which they then must carry with them. Nor do hunters wish to transport and install a bulky large urinal container in the stand or blind. Yet another proposed solution is a scent minimizing slurry packet to pour over urine that is excreted onto the ground, yet this solution requires the user to continually repurchase and carry packets on their persons. 
         [0015]    There is a need for a urination system that is small and lightweight, easy to transport, set up and use, and inexpensive. There is a need for such a system to effectively and quietly eliminate the urine as well as effectively minimize the urine scent. 
       NOTATION AND NOMENCLATURE 
       [0016]    Certain terms are used throughout the following description to refer to particular method components. As one skilled in the art will appreciate, design and manufacturing companies may refer to a component by different names. This document does not intend to distinguish between components that differ in name but not function. 
         [0017]    In the following discussion, the terms “including” and “comprising” are used in an open-ended fashion, and thus should be interpreted to mean “including, but not limited to . . . .” Also, the term “couple” or “couples” is intended to mean either an indirect or direct connection. Thus, if a first device couples to a second device, that connection may be through a direct connection or through an indirect connection via other intermediate devices and connections. Moreover, the term “method” means “one or more components” combined together. Thus, a method can comprise an “entire method” or “sub methods” within the method. 
         [0018]    “Filtration medium” may comprise charcoal, coal, zeolyte or any readily obtainable, low cost substance that minimizes odor and assists in filtration, effective for the purposes described herein. 
         [0019]    “Scent minimizing substance” may comprise any odor minimizing substance effective for the purposes described herein. 
       SUMMARY OF THE INVENTION 
       [0020]    The disadvantages shown in the prior art are solved by a method and device for outdoor urination and minimization of human urine scent while in a tree stand, elevated hunting blind, ground blind or other outdoor area where traditional bathroom facilities are unavailable, yet disposal of urine and minimization of urine scent is important. 
         [0021]    The scent minimizing outdoor urinal of the disclosed invention includes a urine collection container having a top end with a closeable lid and a bottom end with a closeable spout. The urinal includes a hose extending from the urinal to a buried disposal bucket, having one end that fits over the bottom end of the urine collection container and an opposite end that lodges inside the buried bucket. The buried bucket has a closed lid and may have a hole with a slightly larger diameter than the hose so the hose can protrude into the bucket, which also has a filtration medium in it. The bucket further has drainage holes such that the urine enters the bucket via the hose, is dispersed through the filtration medium and then exits the bucket into the ground via the drainage holes in the bucket. 
         [0022]    An objective of the disclosed invention is to provide urinal facilities to a hunter in close proximity of where he is waiting for the game. 
         [0023]    A further objective of the disclosed invention is to minimize urine odor after voiding. 
         [0024]    A further objective of the disclosed invention is to cleanly and permanently dispose of the urine without the need for transporting the urine to a designated location. 
         [0025]    A further objective of the disclosed invention is to minimize sound when the user needs to void.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0032]    Although tree stands or elevated hunting blinds are the most obvious embodiment, even ground level blinds, camping spots, construction sites or any outdoor areas where bathroom facilities are unavailable may prove useful sites for the disclosed invention. The disclosed invention presents a low cost, easy to assemble and easy to transport system for outdoor urination with scent minimization. 
         [0033]    A preferred embodiment of the urine collection container of the system includes a generally funnel shaped container with a wide top end and a narrow bottom end. The top end may be closed with a plastic snap on lid or other type of lid and the bottom end may be closed with a twisting on/off valve or spout to seal out urine scent after elimination. A flexible tubing or hose of small diameter clamps onto the bottom end of the urinal container and is of sufficient length to allow the opposite end to be buried into the center of an underground urine disposal device. The underground urine disposal device contains a perforated bottom end and layers of carbon medium in specific size and placement to encourage the efficient disbursement of urine into the ground and the elimination of associated urine scent. In an additional embodiment, the urine scent can be effectively flushed from the apparatus by a flushing scent minimizing rinse. In one embodiment, fine charcoal mixed with water may be used as the scent minimizing rinse by pouring the mixture into the urinal container after urination. 
         [0034]    In an alternative embodiment, the urine collection container may be a bag, a bottle or any other liquid impermeable hollow container effective for voiding into. 
         [0035]    Carbon and zeolyte are effective means of scent removal and are relatively inexpensive and easy to obtain. 
         [0036]      FIG. 1  illustrates the disclosed preferred embodiment for the eradication of human urine and human urine scent when on an elevated hunting blind  10  or tree stand. The urine collection container  12 , is depicted as generally funnel shaped and is attached to a corner or side of the interior of the blind  10 . 
         [0037]    In the preferred embodiment, a hose  14  is connected to the base end of the urine collection container  12 , with the opposite end of the hose  14  terminating midway into an underground urine disposal device (UUDD)  16 . The hose  14  is of a length sufficient to reach from the end of the urine collection container  12  to the midway point of the UUDD  16 . The hose  14  used in the preferred embodiment is a black UV resistant flexible vinyl tubing of approximately 17 feet in length and 1/2 inch in diameter, however, one skilled in the art will appreciate that any tubing, conduit or a hose of any reasonable diameter, sufficient to allow the passage of fluid, may be used, and the length used will vary with the height of the tree stand, elevated platform, or ground structure. The hose  14  may be attached to the leg  18  of the elevated hunting blind  10  or, in the case of a tree stand, the tree trunk itself, by any reasonable attachment means  20  such as zip ties, rope, plastic straps, wire or other means. The attachment prevents unwanted movement of the hose  14  by wind or other disturbances. 
         [0038]    In a preferred embodiment, the UUDD  16 , is buried a few inches underground near the leg  18  of the elevated platform  10  or near the tree trunk and can be easily removed when blind location is changed. 
         [0039]    In  FIG. 2  a preferred embodiment of the urine collection container  12  is depicted. The urine collection container  12  may be generally a funnel shape although other shapes may be used and the drawings and descriptions herein are not intended to limit the shape. In the preferred embodiment, the urine collection container  12  has a twist on/off valve  22  at the base of the container  12  to further seal out scent after elimination has occurred. The urine collection container  12  may have a snap on or screw on lid  24  which may or may not be used as desired. In the preferred embodiment, the urine collection container  12  has a handle  26  for ease of use, although this is not a necessary element. The urine collection container  12  depicted in  FIG. 2  is preferable due to the handle  26  and twist valve  22  which make the container easier to use and more effectively eliminates any possible residual urine scent. 
         [0040]    In the preferred embodiment the urine collection container  12  may be simply hung on a nail driven into the tree or the wall of the elevated platform  10 . In an alternative embodiment it may also be hung by a strap, though one skilled in the art will appreciate that any reasonable fastening means may be used to hang the urine collection container in the elevated platform or blind, including straps, wire, hooks, clips, Velcro™, ties, zip tie or other available means. 
         [0041]    In the preferred embodiment, and as depicted in  FIG. 3 , the UUDD  16  comprises a two gallon bucket  26  that has a lid  28  and a sufficiently perforated bottom  30 , to allow drainage of the urine into the surrounding underground. The bucket  26  may be three gallons or any other size desired although two gallons provides sufficient space for the filtration medium and is small enough for easy storage and transportation. In the preferred embodiment, the bucket  26  has a hole  32  in the middle of the lid  28  that is just slightly larger diameter than the hose  14 . 
         [0042]    In the preferred embodiment, the UUDD  12  is buried underground with, in a preferred embodiment, at least a couple of inches of dirt over the lid  28 . The bucket  26  contains a filtration medium  34  which will typically be activated carbon and zeolyte. The carbon medium allows for disbursement and drainage of the urine while eliminating the urine scent. 
         [0043]    As a preferred embodiment of final disposal of the human urine and elimination of the human urine scent, a final step may be taken as illustrated in  FIG. 4 . The user performs the following steps: First step  40 : void into urine collection container; Second step  42 : mix a packet of carbon medium with water; Third step  44 : rinse urine collection container by pouring packet mixture in urine collection container; Fourth step  46 : twist valve or spout at base of urine collection container to off, or if no valve, place lid on container; Fifth step  48 : urine and urine scent is eradicated. These steps minimize if not eliminate the presence of odor in the stand or blind. The user can pour the packet of scent minimizing filtration medium into a bottle of water and shake up the mixture for ease of use. The packet may contain fine pieces and particles of activated carbon and zeolyte or activated carbon only. The packet may also contain charcoal plus an activating acid if desired. A premixed solution of carbon and water or carbon and acid are alternative embodiments of the rinsing and flushing process. 
         [0044]    The method and device disclosed herein effectively disposes of human urine, while minimizing noise, odor and movement for a user who does not have traditional urinal facilities available. The disclosed method and device eliminates the need to climb up and down the elevated platform or tree or leave the ground level site, which can scare away the wildlife. 
         [0045]    The system is uniquely designed such that all of the elements of the system (hose, attachment straps or ties, urine collection container, carbon filtration packet and carbon filtration medium) all fit in the bucket for ease in packaging, marketing and transportation. The bottled water may be purchased separately by the end user or may be sold with the system. 
         [0046]    Packets of the carbon medium used for rinsing the urine collection container and tubing may also be packaged and sold separately for replacement purchase by the end user. 
         [0047]    The method and device disclosed herein achieve significant advantages over the prior art in that it is easy to set up, small and portable enough to carry out to the tree stand or elevated blind, blends in well with the environment, is quiet to use, is quick and easy to use, and eliminates the need to carry one&#39;s urine or to climb up and down the stand, or leave a ground blind. The method and device disclosed herein depict a far superior attainment of urine disposal with urine scent minimization, while also minimizing noise and movement, than the prior art methods. 
         [0048]    While the disclosed method and apparatus has been described in conjunction with the preferred embodiments thereof, many changes, modifications, alterations and variations will be apparent to those skilled in the art. The invention should therefore not be limited to the particular preferred embodiment disclosed but should include all embodiments that could fall within the scope of the claims. 
         [0049]    Accordingly, the preferred embodiments of the invention shown in the drawings and described in detail above are intended to be illustrative, not limiting, and various changes may be made without departing from the spirit and scope of the invention as defined by the claims set forth below.
