CROSS-REFERENCE TO RELATED APPLICATIONS 
       [0001]    This application claims benefit of U.S. Provisional Patent Application Ser. No. 60/825,473, filed Oct. 18, 2006, entitled Fuel Tank Apparatus. 
     
     BACKGROUND OF THE INVENTION 
       [0002]    1. Field of the Invention 
         [0003]    The present invention relates in general to an apparatus to prevent a cylindrical storage container from moving while transported inside a vehicle. More particularly, the present invention relates to an apparatus that can be positioned around at least a portion of a cylindrical container to prevent undesired movement of the container or like objects. 
         [0004]    2. Discussion of Related Art 
         [0005]    Tanks and containers are commonly found in today&#39;s market having a variety of uses in both industrial and consumer applications. Often, storage tanks are transported inside a vehicle from one place to another. Most tanks by design are round, cylindrically shaped and often become unstable during transportation. Commercial vehicles are sometimes custom fitted with hardware or fasteners to securely mount tanks from moving while transported. Private vehicles, on the other hand, do not include any mechanisms for mounting tanks or preventing uncontrolled movements within the vehicle. Although most storage containers and tanks are designed with features to prevent the container from leaking, tanks rolling around in a moving vehicle creates a risk of impacting the inside fender, causing damage to the automobile body panel. 
         [0006]    Many tanks, commonly filled with fuel, water, or other liquids, solids or gas materials and are refilled and reused frequently. There are millions of tanks sold and refilled each year in the United States alone. There are large numbers of vehicles unsafely transporting tanks with limited ability to prevent tanks from moving while transported. Storage containers and tanks often become dirty and can contaminate the interior of a vehicle and other areas they may contact during handling or transport. For example, gas-grill type propane tanks are frequently used for cooking food and may become greasy or dirty and contaminate surfaces they are in contact with during transport. 
         [0007]    There are various types of hardware available that may be adapted to secure a tank to the inside of a vehicle. However, such hardware requires altering the vehicle body or drilling then fastening hardware to adapt to a vehicle. Many fasteners commonly found on the market can be customized to barricade a tank to a specific area within a vehicle during transport to prevent tanks from moving. Fasteners, straps and like members found on the market today are not readily available, adaptable or easy to assemble to prevent tanks from moving. Products such as tank stands, configured with hardware and other related components can be found fixed to a gas grill to securely fasten the tank to the frame. Some devices found on the market to are bulky and not easy to store taking up valuable space inside a vehicle in some cases require additional components that may not readily available for use when needed space. Limitations of space within the vehicle and permanent alteration of the vehicle body prove to be a disadvantage of current devices on the market today. They do not offer a method to prevent the tank from tipping, rolling nor an economical compact design to limit movement during transportation.

     DETAILED DESCRIPTION 
       [0027]    The present invention operates to prevent movement of a cylindrical tank or like containers during transport. The apparatus includes a pair of stops which are configured to form a wedge like object on both sides of the tank to prevent tank movement. The stops are of substantial size, shape and positioned to prevent the tank from rolling and or moving. Various shaped stops are disclosed in various embodiments of the invention (i.e. round, triangular, hollow, collapsible). Also, different structures are used to position the stops in various embodiments of the invention. 
         [0028]      FIGS. 1 and 2  disclose a first embodiment of the invention. The structure of the tank apparatus  10  is shown in perspective view in  FIG. 1 . The tank apparatus of this embodiment includes a sheet  11  and at least two anti-roll stops  12 ,  13 . The stops are of triangular shape and extend away from the sheet  11  to form a wedge preventing movement of the tank or like container. Although the stops are shown in triangular geometry, other stop geometric configurations can be utilized to prevent movement.  FIG. 1  illustrates the sheet  11  extending beyond the stops  12 ,  13 . However, the sheet  11  may be sized to end at the outer edges of the stops  12 ,  13 .  FIG. 2  illustrates the tank apparatus with a tank  1  positioned thereon. The stops  12 ,  13  are positioned on either side of the tank  1  in contact with the outer sides. The stops  12 ,  13  are preferably of triangular shape. Of course, other shapes, sizes and configurations could be used. The configuration of the stops may be adapted with various diameter tanks. The stops  12 ,  13  should be of sufficient size so that the tank  1  cannot roll over them during normal transport within the vehicle. For a standard 12″ diameter tank, a stop height of 1½-3″ is sufficient. Preferably, the stops  12 ,  13  are substantially the same length as the length of the tanks outer most diameter, or somewhat equivalent in size to prevent movement. However, they may be of any length sufficient to hold the tank  1 . A larger or longer tank  1  may require larger and/or longer stops  12 ,  13 . While the stops are shown as having planar sides as with a triangle, they may also be arced to mate with the surface of the tank  1 . The stops may be fixedly attached, detachable, welded or fastened by other methods. The stops may be configured of plastic, foam, and board or other like materials. The stops may be hollow or solid for design or cost reasons. 
         [0029]    The sheet  11  and stops  12 ,  13  may be of various materials and constructed using various techniques. They may be of the same material or of different materials. In one embodiment, the sheet  11  and stops  12 ,  13  are formed as a single unit of plastic material. According to another embodiment, the sheet  11  is formed separately from the stops. The sheet  11  may be of fabric, plastic, metal, polyester, non-woven polypropylene, PVC, rubber or other like materials. The sheet can also be formed of multiple materials joined together. Preferably, the back side of the sheet  11  is of a material which does not easily slide when placed on a substantially flat surface inside a vehicle. A high coefficient of friction material may be used for this purpose to prevent movement (i.e. rubber, elastomer, PVC, or like materials). Additionally, since many vehicles have carpeting (i.e. loop material) within the trunk or other areas inside the interior of the vehicle, a hook like material or hook fastener, can be attached to or part of the sheet  11 . The hook like material or hook fastener can attach to the carpet of the transport vehicle to prevent movement of the sheet  11  within the vehicle. Magnetic materials or components may also be used in a similar method or construction within the sheet, having the ability to attach to various body panels of the vehicle. 
         [0030]    The stops  12 ,  13  may be formed of paper, plastic, polyethylene foam, wood, metal, cardboard, etc. They may be formed as a single solid part, a hollow part or configured to form a shape to prevent movement (i.e. triangle, circle, wedge, or other anti-roll shape). They may be a single material or created from multiple materials, and may be weather resistant or biodegradable, recyclable, or environmentally friendly materials. All of the sides of the triangle need not be part of the stops  12 ,  13 . In one embodiment, the stops  12 ,  13  may include one side facing the tank and triangular or other shaped supports to properly position the side configured to be in a close proximity of the tanks outer diameter. A cylinder of material may be formed with the sheet  11  to hold the stops  12 ,  13  in position. Alternatively, the stops  12 ,  13  may be attached to the sheet  11  with adhesives, welded, fasteners, permanent or temporary fastening methods. Additionally, the stops  12 ,  13  may be removably attached to the sheet  11 . For example, hook and loop fasteners may be used on the stops  12 ,  13  and sheet  11 . This would allow the distance between the stops  12 ,  13  to be adjusted to accommodate different sized tanks. 
         [0031]    Another embodiment of a tank apparatus  100  of the present invention is illustrated in  FIGS. 3 and 4 . This embodiment also includes a thin sheet of flexible material  111  and two stops  112 ,  113 . In the first embodiment discussed above, the sheet  111  is planar, configured as a mat to be placed in the trunk or floor of a vehicle for transport. In the second embodiment, the sheet  111  is sized to adapt to the diameter of tank  1 . The outer surface of the apparatus device  10  of  FIG. 1  is placed towards the tank  1  in one configuration. On the other hand, the upper surface of the apparatus device  100  of  FIG. 4  is place away from the tank  1  in yet another configuration where the stops are positioned to prevent the tank from moving and the apparatus is attached to the tank. The apparatus is configured with at least one fastening device. For illustration, a pair of fasteners  114 ,  115  extends from one end of the sheet  111 . A second mating pair of fasteners  116 ,  117  is positioned on the other end of the sheet  111 . The first pair of fasteners  114 ,  115  and the second pair of fasteners  116 ,  117  are configured to hold the sheet  111  in place around the tank  1 . They may include hook and loop fasteners, elastic, snaps, magnetic closures, ties, or other fastening devices. The fastener may further be configured to adjust and adapt to various diameter tanks. While the embodiment illustrated in  FIGS. 3 and 4  show the fasteners  114 ,  115  extending from the sheet  111 , they may be formed as part of the edge of the sheet. Alternatively, the entire edge of the sheet  111  may be used as a fastener or further configured to be made of a loop material, and have at least one hook fastener securely fastened to one end to secure the tank or like container within the apparatus. The hook material can be configured to a portion of the apparatus, or selectively attached to prevent movement of the tank or container. 
         [0032]    In use, the apparatus  100  of this embodiment is wrapped around a tank  1  and secured using the fasteners  114 ,  115 ,  116 ,  117 . Preferably, the sheet  111  has a length which corresponds with the circumference of the tank  1  or at least a portion of the tanks circumference that may come in contact with the vehicles interior. The stops  112 ,  113  are attached to the outer surface of the sheet  111 . They are positioned such that they contact a point on the vehicles interior&#39;s surface one side of the tank  1  to prevent rolling. In addition, the stops are located opposite of one a point of the tanks&#39; diameter point of contact on the vehicle&#39;s interior surface. The stops  112 , 113  in one embodiment can be constructed of a hook material on at least one side to further prevent two or three dimensional movement of the apparatus and tank within the vehicles. 
         [0033]    As with the first embodiment, the sheet  111  and stops  112 ,  113  may be formed of various materials and construction methods. The stops  112 ,  113  may be fixed in position or adjustable to accommodate different diameter tanks. The outer surface of the sheet  111  and/or stops  112  may include a material or structure, such as fabric, rubber, or plastic magnetic or hook fasteners, which operates to prevent movement of the tank apparatus  100  within the vehicle. When not in use, the anti-roll apparatus  100  can be easily rolled or folded to minimize the space required for storage. 
         [0034]      FIG. 5  illustrates another embodiment of the tank apparatus  210  of the present invention. As in the prior embodiments, this embodiment includes a resilient body  211  and stops  212 ,  213 . In the prior embodiment, the sheet  111  was flexible and wrapped around the tank. In this embodiment, the resilient body  211  includes a spring-like material  218 ,  219  at least along the edges. The spring-like material forms a “C” shape of a size similar to the periphery of a tank. The edges of the resilient body  211  are moved apart to insert the tank within the tank apparatus  210 . When released, the spring-like material forces the resilient body  211  around the tank to hold it in place. As in the prior embodiments, the stops  212 ,  213  are attached to the resilient body  211  at positions to prevent rolling of the tank. The stops  212 ,  213  may be permanent, adjustable or removably attached. As with the second embodiment, a fastener (not shown) may be used at the edges of the resilient body  211  to securely fasten the tank apparatus to the tank. The edges may be configured with a high coefficient of frictional material to prevent movement from the tank to the apparatus and from the apparatus to the vehicle interior. Handles  220 ,  221  may also be formed in the resilient body  211  to make carrying the tank easier, although handles are shown, one handle may be configured to the apparatus. Depending upon the materials used for the resilient body  211 , the handles  220 ,  221  may be merely holes formed in the resilient body. Alternatively, as illustrated in  FIG. 6 , a separate handle  222  may be formed along the edge of the resilient body  211 . The handle  222  has a separate handhold  223  to allow for easy gripping. The handles on each side of the resilient body  211  may be positioned to allow them to be held with one hand or two hands for carrying the tank. Further illustrated in  FIG. 13 , handles may be formed in the material to provide consumers a place to grasp the apparatus. 
         [0035]    Tanks can become extremely dirty. Propane tanks used with barbeque grills often are greasy. The tank apparatus of the present invention provides a cover for the tank of like containers to prevent the dirt or grease from soiling the interior of the vehicle. Preferably, the tank apparatus is of a material which is easily cleaned. Additionally, as illustrated in  FIG. 7 , inserts  125  may be used on an interior surface of the sheet  111  of any embodiment of the invention.
