BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The present invention is broadly concerned with decorative cover assemblies designed to cover a propane tank (e.g., a standard 20 lb. household tank) and to present the three-dimensional appearance or likeness of a sports-related item, such as athletic headgear or athletic balls. More specifically, the invention is directed to such cover assemblies which may be separate from a propane tank or integrated therewith, and which may be formed of any suitable material, such as metal or synthetic resin. Exemplary cover assemblies in accordance with the invention may be solid, hollow, or inflatable. 
         [0003]    2. Description of the Prior Art 
         [0004]    A tailgate party is a social event held on or around the open tailgates of vehicles. Tailgating traditionally involves consuming beverages and grilling food. Tailgate parties often occur in the parking lots of stadiums and arenas before, during, and after sporting events. For example, tailgate parties have become particularly popular in the U.S. as social gatherings that take place in stadium parking lots before football games. As an adjunct to such parties, tailgaters have flags, pennants, outerwear such as shirts, jackets, and caps, and all manner of other items, bearing the logo and/or name of their favorite team. Such team identification is deemed essential by tailgate participants. 
         [0005]    Dedicated tailgaters sometimes have elaborate portable equipment for grilling of foods. Thus, many tailgaters have portable propane grills making use of one or more standard household propane tanks. These tanks are generally white in color and are positioned beneath the grill. As such, the tanks are unsightly and do not contribute to the festive atmosphere of a tailgate party. 
         [0006]    It would therefore be a boon to tailgaters if unattractive and innocuous propane tanks could be decorated in a manner consistent with a tailgate party scheme, and particularly to give the appearance or likeness of a sports-related item consistent with the tailgate party theme. 
       SUMMARY OF THE INVENTION 
       [0007]    The present invention addresses the problem outlined above, and provides sports-related cover assemblies for propane tanks, each comprising a decorative body having an inner and an outer surface. The inner surface of the body is designed to mate with a propane tank (i.e., the inner surface is configured to rest upon or otherwise be supported by a propane tank wall), while the outer surface is configured to present a three-dimensional likeness or appearance of a sports-related item. The cover assembly may be separable from a propane tank, can be integrated with the tank, or the tank may be formed with the decorative surface aspects, such that there is no separate tank. The outer surface of the cover assembly is typically designed to give the three-dimensional likeness or appearance of things such as athletic headgear, athletic footwear, athletic balls, or other athletic equipment. 
         [0008]    As used herein, with reference to the cover assembly bodies of the invention “three-dimensional” means that a given cover assembly body presents a contoured or concavo-convex outer surface, preferably with portions of the outer surface spaced a significant distance (most preferably at least about one-half inch) from the proximal propane tank wall. Such three-dimensional cover assemblies thus are distinctly different from conventional two-dimensional images printed on a simple tank cover or the like. 
         [0009]    Hence, in the case of a cover assembly body having a simulated athletic headgear outer surface, the headgear is broadly selected from the group consisting of athletic helmets, caps, and hats, e.g., helmets for racing, football, lacrosse, baseball batting, rodeo, fencing, skiing and other winter sports, bicycling, hockey, and boxing. In the case of athletic footwear, the cover assembly body may present the three-dimensional appearance of footwear for soccer, football, hockey, basketball, track, skiing, boxing, golf, ballet, and bicycling. A wide variety of athletic cover assembly bodies may give the three-dimensional appearance of a simulated athletic ball, for example balls selected from the group consisting of baseballs, basketballs, cricket balls, tennis balls, footballs, rugby balls, lacrosse balls, baoding balls, billiard balls, table tennis balls, bowling balls, handballs, soccer balls, wiffle balls, polo balls, golf balls, racquet balls, beach balls, and volley balls. Other cover assembly bodies giving the three-dimensional appearance of simulated sports-related items may include covers giving the three-dimensional appearance of athletic apparel selected from the group consisting of jerseys, shirts, jackets, shorts, pants, stockings, pads, and gloves, hockey pucks, curling stones, racquets, mallets, baseball bats, hockey sticks, and basketball nets. In short, the scope of the present invention is limited only by the imagination of the fabricator. 
         [0010]    It will also be appreciated that, in most instances, the outer surface of a given cover assembly would also include the name and/or logo of a specific team or athlete. In this way, the user can both decorate an otherwise bland-looking propane tank, while also proclaiming loyalty to the user&#39;s favorite team or athlete.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0031]    Turning now to  FIGS. 1-5 , a combination  30  is illustrated including a standard household propane tank  32  and a detachable, two-piece cover assembly  34 . The tank  32  (see  FIG. 4 ) includes an upright hollow propane-holding container  36  having a circular base  38  and rounded upper and lower shoulders  40 ,  42 . A standard propane tank valve  44  is secured at the top of the tank, with a carrying and connection cage  46  disposed partially about the valve  44 . It will be appreciated that the tank  32  is itself wholly conventional. 
         [0032]    The cover assembly  34  in this embodiment is made up of a body having front and rear sections  48  and  50  which are hingedly interconnected by means of hinge structure  52 . The edges of the sections  48  and  50  opposite hinge structure  52  is provided with mating latch structures  54  and  56 . As best seen in  FIG. 5 , the inner surface  58  of the cover assembly  34  is made up of front and rear section inner surfaces  60  and  62 . These surfaces are designed to substantially surround the tank  32  and are further provided with a number of inwardly extending engagement blocks  64 . As illustrated in  FIG. 4 , the blocks  64  are designed to firmly engage the wall of container  36  so as to prevent inadvertent axial or rotational movement of the cover assembly  34  relative to tank  32 . It will further be observed that the cover assembly sections  48  and  50  cooperatively present an upper opening  66 , which is disposed about cage  46  and valve  44 , and a lower opening  68 , which extends about the lower portion of tank  32 . 
         [0033]    In this embodiment, the outer surface  70  of the assembly  34 , made up of front and rear section surfaces  72  and  74 , give the three-dimensional likeness and appearance of an automobile racing helmet. Thus, the front surface  72  has a simulated visor  76  presenting concavo-convex surfaces, as well as a downwardly and outwardly extending chin section  78 . In use, the cover assembly  34  is opened as depicted in  FIG. 5 , and closed about the tank  32  so that the latch structures  54  and  56  mate and engage. Removal of the cover assembly is accomplished by opening the latch structures and swinging the cover sections  48  and  50  apart. 
         [0034]      FIGS. 6-9  illustrate another embodiment in the form of a combination  80  made up of an integrated propane tank  82  and cover assembly  84 . In this case, the assembly  84  has a body presenting an outer surface  86 , giving the three-dimensional appearance or likeness of a football helmet. The latter has a rounded surface characteristic of football helmets, along with simulated ear holes  88  and an outwardly projecting mask  90 . The combination  80  further includes an upper valve  44  and cage  46 , as previously described. Internally, the combination  80  may have a standard household propane tank, as described above, with the cover assembly  84  welded or otherwise permanently secured to the tank. 
         [0035]      FIGS. 10-13  illustrate another form of the invention made of a combination  92  having a standard propane tank  32 , described previously, and a molded, one-piece synthetic resin cover assembly  94 . As best seen in  FIGS. 12 and 13 , the cover assembly  94  has a body presenting an upper opening  96  designed to surround cage  46  and valve  44 , and a lower opening  98 . The inner surface  100  of the assembly  94  is configured to closely mate with the outer wall of container  36  and shoulder  40 . The assembly  94  may thus be installed on tank  32  simply by positioning the lower opening  98  above the tank and sliding the cover assembly  94  onto the tank to assume the position shown in  FIG. 12 . The cover can of course also be readily removed from the tank  32  by reversing this procedure. The cover assembly  94  can be fabricated from any suitable synthetic resin material, such as compressible polyurethane  102 . The outer skin or surface  104  thereof is configured to give the three-dimensional likeness or appearance of an automotive racing helmet, as in the case of the first embodiment. 
         [0036]      FIGS. 14-16  depict another embodiment, in the form of combination  106  again comprising a standard propane tank  32  and a cover assembly  108 . The latter is in the form of a body having an inner surface  110 , an outer surface  112 , an upper opening  114 , and a lower opening  116 . Thus, the cover assembly  108  is a unitary structure, similar to the cover assembly  94 . The inner surface  110  is designed to closely mate with the outer surfaces of tank  32 , whereas the outer surface  112  gives the three-dimensional likeness or appearance of a football helmet, including simulated ear holes  118  and an outwardly projecting face mask  120 . In this instance, however, the cover assembly  108  is a substantially rigid, hollow body presenting air space  122  between the inner and outer surfaces  110  and  112 , and can be conveniently produced by standard rotary molding or other conventional techniques. The use of assembly  108  is the same as that described with respect to unitary cover assembly  94 , i.e., the cover  108  can be positioned above a tank  32  and slid into place, as shown in  FIG. 16 . 
         [0037]      FIGS. 18 and 19  depict a combination  124  again comprising a standard propane tank  32  with an inflatable unitary cover assembly  126 . The assembly  126  is in the form of a body having an inner wall  128 , which closely conforms with the wall surfaces of tank  32 , and an outer surface  130 , upper opening  132 , and lower opening  134 . The outer surface  130  is equipped with an inflation/deflation nipple  136 , and gives the three-dimensional likeness or appearance of a football helmet, including ear holes  138  and face mask  140 . In use, the mask assembly  126  is inflated through nipple  136 , and the inflated assembly may be installed in the same manner as the previously described unitary cover assemblies. Alternately, the cover assembly  126  may be installed on the tank  32  in a deflated condition, and inflated in place. If necessary, the assembly  126  can be deflated before removal from tank  32 . 
         [0038]      FIG. 20  illustrates a combination  142  comprising a standard propane tank  32  and a cover assembly  144 . The assembly  144  has a body of unitary, one-piece construction as in earlier embodiments. Thus, the cover assembly  144  includes an inner surface (not shown) configured to mate with the outer surface of tank  32  and has upper and lower openings  146 ,  148  allowing the assembly to be positioned over the tank  32 . In this instance, the outer surface  150  of the assembly  144  presents the three-dimensional appearance of a basketball having simulations of typical sections and intervening seams. The cover assembly  144  may be hollow, filled, or inflatable. 
         [0039]    It will thus be appreciated that the present invention provides a wide array of sports-related propane tank covers and combinations, which may be sectionalized, as illustrated in  FIGS. 1-5 , or unitary, as depicted in  FIGS. 6-20 . Alternately, combined assemblies can be made wherein the tank and cover assembly are unitized, as illustrated in  FIGS. 6-9 . 
         [0040]    Furthermore, while the invention has been illustrated in the context of standard household propane tanks, the principles of the invention can be equally applied to larger or differently-configured propane tanks. Thus, the term “propane tank” as used herein should be understood to embrace all shapes and sizes of propane tanks. Additionally, the cover assemblies may be separate from or used with any size or shape of propane tank, or a propane tank may be fabricated from two or more sections by welding the sections together, wherein at least some of the sections have preformed surface design features in accordance with the invention, so that the completed tank has the likeness or appearance of a sports-related item. It will be appreciated that this form of the invention does not make use of a pre-existing or pre-formed propane tank.
