     FIELD OF THE INVENTION 
       [0002]    The instant invention relates generally to protective covers, and more particularly to a removable seat cover which contains liquid container storage capability. 
       BACKGROUND OF THE INVENTION 
       [0003]    Whether driving to work, sitting at their office jobs, or lounging at the beach, individuals encounter seats or chairs as part of their normal daily routines. Daily use eventually results in the seating portion of the seats or chairs becoming worn or damaged before the frame of the seat or chair. This can result in expensive recovering or replacement of the seat or chair. As a result, seat covers have been designed to provide protection to the seat from wear and tear, thereby extending the useful life of the seat. In addition, seat covers are also used to provide a more comfortable and enjoyable experience for the user. Accordingly, numerous enhancements to the type of materials used and the way in which the seat covers are designed or attached to the seat have been developed over the years. Numerous seat covers exist in the prior art, including U.S. Pat. Nos. D271,266, D879,939, D396,983, D499,297, D506,345, D610,854, and D610,855.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0042]    While the present invention is susceptible of embodiment in various forms, there is shown in the drawings and will hereinafter be described a presently preferred, albeit not limiting, embodiment with the understanding that the present disclosure is to be considered an exemplification of the present invention and is not intended to limit the invention to the specific embodiments illustrated. 
         [0043]    Referring to  FIGS. 1A-2B , a removable seat cover  10  in accordance with the instant invention, is shown. The seat cover  10  may be made of any material, or combinations of materials, known to one of skill in the art, including but not limited to moisture impermeable materials, absorbent materials, wicking materials, waterproof materials, hydrophobic, non-absorbing materials, or rubberized backing materials. The seat cover  10  may be made of flexible material to allow the user to store the seat cover  10  in a folded or rolled-up state. The removable seat cover  10  contains an elongated material having a first front surface  12  and a second back surface  14 . The seat cover  10  is defined by a top side  16 , a bottom side  18 , and opposing sides  20  and  22 . The distance between the top side  16  and the bottom side  18  defines the length of the seat cover  10 , which can be made in various lengths to accommodate the object it covers or is intended to cover. The distance between opposing sides  20  and  22  defines the width of the seat cover  10  and can be varied depending upon the width of the object it covers or is intended to cover. The shape of the seat cover can vary as well, thereby allowing for the seat cover  10  to be adaptable to a variety of sitting or lying surfaces. 
         [0044]    The seat cover  10  may include a plurality of pockets which effectively divide the seat cover  10  into a plurality of defined areas. For example, a first pocket  24  defines an upper portion  26 , see  FIG. 2A . The upper portion  26  is generally placed upon the upper end of a seat, typically at or near where the head and/or the shoulder of the user rests. The first pocket  24  has an open end and a closed end to define an inner cavity adapted to receive and support objects. The first pocket  24  is preferably sealed by a sealing member, such as a zipper  28 . While each of the figures illustrates the cover using a zipper  28 , other means, or combinations thereof, of closing a pocket, such as but not limited to, use of fabric loop and fasteners, such as VELCRO, buttons, snaps, stitching, or the like, may be used as well. The pocket may be formed as a hidden pocket or may extend outwardly like a pouch. Referring back to  FIG. 1A , a second pocket  30  defines a lower portion  32  of the seat cover  10 . The lower portion is generally placed at the bottom end of the object to be covered, typically where a user&#39;s feet and legs rest. The second pocket area  30  is closed by use of the zipper  28 . The distance between the upper portion  26  and the lower portion  32  is the main body portion  34 . The main body portion  34  may contain curved areas  36  and  38  which are designed to provide coverage of the areas of a seat where the backrest meets the seating area. In order to provide additional storage, the seat cover  10  may optionally include one or more additional pockets  39  enclosed by a zipper  28 . While the additional pocket  39  is illustrated on surface  14 , such pocket may be positioned on either surface  12  or  14  and placed along any part of the surface. Referring to  FIG. 1B , two opposing pockets  39  are positioned along the upper portion  26 . The two opposing pockets  39  are sized and shaped to hold personal belongings such as money, credit cards, identification, a portable media player which is capable of storing and playing digital media (audio, video, and the like), such as an APPLE IPOD, or other electronic devices such as cell phones, cameras, or tablet computers. In a preferred embodiment, the second pocket  30  positioned on the first surface  12  is aligned in a substantially parallel manner and adjacently connected to the pocket  39  positioned on the second surface  14 , thereby forming a dual pocket assembly  41 , see  FIG. 2B . 
         [0045]      FIG. 3  illustrates an alternative embodiment of the seat cover  10  in which the upper portion  26  contains a pocket which is sealed by stitching  40 . In the lower corner of the upper portion  26  is a valve  42 , such as a Boston Valve or an oral inflation valve commonly used in blow-up beach balls, for easy inflation and deflation.  FIG. 4  is a partial view of  4 - 4  of  FIG. 3 , illustrating the valve  42  attached to a portion of surface  12 . The valve  42  contains a main body  44  with sealing cap  46 . The valve  42  is preferably a one-way valve. Inflation of the upper portion, therefore, may be commenced by squeezing main body  44  while simultaneously exhaling air within opening  48 . As the air is blown in, the upper portion  26  expands, forming an air cushioned area for placing a portion of a user&#39;s body, such as the head, thereupon. Once the desired amount of inflation has been reached, cap  46  is secured to opening  48 .  FIG. 5  illustrates the seat cover  10  having a fully inflated upper portion  26 . 
         [0046]    Referring back to  FIG. 3 , the lower portion  32  contains one or more independent compartments, illustrated herein as cylindrical pockets  50  and  52 . The cylindrical pockets, which may be formed by continuous side walls  49  or  51 , are constructed and arranged to hold various items, particularly liquid drinks or beverages, such as soda or beer cans  53 , water bottles, or the like which can be inserted through opening  55 . The cylindrical pockets, as well as any other pocket constructed and arranged to hold beverages is referred to generally as the beverage container holding pocket. Each of the ends of cylindrical pockets  50  and  52  may optionally contain partial enclosures  56  such as VELCRO strips, see  FIG. 5 , or full enclosures (not illustrated) to provide the capability to partially or completely seal the ends and prevent items stored within from falling out during transportation. To maintain the beverage at a certain temperature, the cylindrical pockets  50  and  52  may be made of or lined with insulating material, such as neoprene, insulating foam liner, insulating foam rubber liner, vinyl, vinyl-plastic, or other insulating materials known to one of skill in the art. Additionally, the cylindrical pockets  50  and  52  may be made of a waterproof material to allow the pockets to be filled with ice. 
         [0047]    Referring to  FIG. 6 , an alternative embodiment of the seat cover  10  is illustrated. The first pocket  24  positioned on upper portion  26  is sized and shaped to receive a pillow  58 . Placed within a beverage container holding pocket  59  is a beverage holding device, or support tray  60 . The beverage container holding pocket  59  is preferably attached to or integrally formed within the lower portion  32  of the front surface  12 , the bottom end of the back surface  14 , or combinations thereof, and has an open end and a closed end to define an inner cavity adapted to receive and support at least one beverage container. The beverage holding device  60  contains a plurality of individual beverage holding cavities  62  which are sized and shaped to accommodate beverages of different sizes and shapes, i.e. cans, bottles, pouches, and is designed to maintain the beverage holders in an upright position through, for example use of loops, a rack, clips, or other securing devices known to one of skill in the art. The beverage holding device may be secured within or to the pocket by any means known to one of skill in the art, such as stitching or use of fastening chemicals. To maintain the beverage at a certain temperature, the beverage container holding pocket may be made of or lined with insulating material, such as neoprene, insulating foam liner, insulating foam rubber liner, vinyl, vinyl-plastic, or other insulating materials known to one of skill in the art. Additionally, the beverage container holding pocket  59  may be made of a waterproof material to allow the pockets to be filled with ice. Once secured therein, the beverage container holding pocket  59  effectively forms a beverage cooler, thereby eliminating the need for a large and bulky traditional style cooler. 
         [0048]    Referring to  FIGS. 7 and 8 , seat cover  10  is illustrated in use. For example,  FIG. 7  illustrates a typical car seat arrangement having two seats  63  and  64  separated by a console  66 . Car seat  63  is illustrated without seat cover  10  and includes a head rest portion  68 , a backrest portion  70 , a seat portion  72 , and a leg rest portion  74 . Seat  64  is illustrated with seat cover  10 . The upper portion  26  is placed over the head rest  68  by placing the head rest  68  within the first pocket  24 . The upper portion  26 , therefore, allows for attachment to the back and/or head rest of the seat, functioning to keep the seat cover  10  in place while making it easy to install and remove. The main body portion  34  of the seat cover  10  is draped along the backrest portion  70  and seat portion  72 . The curved portions  36  and  38  are positioned along the area where the backrest portion  70  and the seat portion  72  meet in order to provide complete coverage. The lower portion  32  is draped over the leg rest portion  74 , thereby ensuring seat  64  is covered by seat cover  10 .  FIG. 8  illustrates seat cover  10  placed on a lounge chair  76 . The seat cover  10  illustrated in  FIG. 8  may be the same seat cover as illustrated in  FIG. 7 . In such a case, the user simply removes the seat cover  10  from the car seat  64  and places it onto lounge chair  76 . As illustrated, the upper portion  26  has an inflated head rest portion, either through the use of air or through the use of an inserted pillow, positioned at the top portion  78  of the lounge chair  76 . The main body portion  34  is draped along the body portion  80  of the lounge chair  76 . The lower portion  32  is placed at the bottom portion  82  of the lounge chair  76 . While not illustrated, the lower portion may contain either the cylindrical portions  50  and  52  or the beverage holding device  60 , thus providing a cooler which stores beverages while the user is lying down on the lounge chair  76 . 
         [0049]    While the seat cover  10  is shown covering a seat or lounge, the seat cover  10  can be applied to other surfaces, such as but not limited to grass, the beach, cement, or pavement. Referring to  FIG. 9 , the seat cover  10  is shown placed over a sand filled environment  84 , such as the beach.
