 The use of smokeless tobacco products is widespread. Chewing tobacco is one particular form of smokeless tobacco. Smokeless tobacco is created through curing tobacco. Curing is a controlled process in which the leaves are gradually dried. Chewing tobacco uses long strands of whole leaves and is consumed by placing a portion of the tobacco between the cheek and gum or teeth and chewing. By chewing the tobacco, the flavor and nicotine is released. Snuff is smokeless tobacco that is grounded into a fine powder and is inhaled through the nose. Moist snuff or dip is placed onto the gums instead of sniffed.
 Smokeless tobacco is usually sold in circular cardboard or metals cans. In order to open the can, the consumer will break the paper seal and remove the lid. However, this method of packaging can lead to problems. The lid can become easily deform and once the paper seal of the can is broken, it fails to provide a tight seal. This results in a loss of moisture, freshness, and flavor. Therefore, a new way to store the tobacco can is needed.
 The present invention overcomes the foregoing and other problems with a smokeless tobacco can holder. The present embodiment of the invention is a way to store a tobacco can after the can has been opened. Since the original lid of the can is inadequate, the present invention proposes a way to seal the product with a new lid. The present invention is a can whose dimensions allow for the typical tobacco can to fit inside. The original lid is discarded and replaced with the invention's lid.
 In the preferred embodiment, the bottom and lid have a diameter of 23/4 inches. The can and lid have a thickness of 1/16 of an inch and are made with stainless steel. In the preferred embodiment, the bottom stands at 5/8 of an inch in height. The top quarter inch of the bottom can is threaded. It has ridges on the internal diameter of the can that allow the top to screw in. The bottom quarter of the lid has the same type of ridges, so it can securely engaged into the bottom.
 The lid of the invention has a gasket at the top of the threading. A gasket is a mechanical seal that fills the space between two mating surfaces that prevents leakage from or into the joined objects. In the preferred embodiment, the type of gasket used is a Teflon or rubber O-ring. Inside the lid, a cork medallion or a round piece of cork which is 1/8 of an inch in thickness is attached to the bottom of the lid. It is surrounded by another O-ring gasket. The gaskets and the cork are necessary for keeping the appropriate moisture level, the freshness and flavor. The original tobacco can is placed inside the invention and the consumer would screw the present invention's lid over the can. This will protect the tobacco and the tobacco can.
 The foregoing outlines some of the more pertinent aspects of the present invention these aspects should be constructed to be merely illustrative of some of the more prominent features and applications of the invention. Many other beneficial results can be obtained by applying the disclosed invention in a different manner of modify the invention as will be described. Accordingly, other aspects and a fuller understanding of the invention may be had by referring to the following detailed description of the preferred embodiment.

 Referring now to the drawings, particularly FIG. 1 and FIG. 2, there is illustrated a perspective view of the smokeless tobacco can holder (11) of the present invention. The can holder (11) comprises a lid (21) and a bottom (31). the container 11 formed is cylindrical with lid (21) interlocking with bottom 31. The can holder 11 can be formed from several materials such as steel, aluminum, wood, cardboard, and plastic.
 Bottom (31) further comprises a base portion (10) and sidewall (20). In the illustrated embodiment, the base (10) consists of a circular, planar surface on which the bottom side of a can of smokeless tobacco will rest. The sidewall (20) extends circumferentially upward from the peripheral edges of the base (10). The sidewall (20) extends to height in which the present invention can contain the can of smokeless tobacco. In the disclosed embodiment, disposed along the interior of the sidewall (20) approximately at the top quarter inch are a set of ridges (30) which allow the lid (21) of the present invention to interlock securely to the bottom (31). Can holder (11) conforms to the shape of smokeless tobacco can. In the illustrated embodiment, the smokeless tobacco can would be circular in shape.
 In normal use, a can of smokeless tobacco is inserted into the can holder (11) with the underside of the can of smokeless tobacco disposed atop the base (10) of the bottom (31). The user discards the original lid of the smokeless tobacco can and engages the lid (21) of the present invention with the bottom (31).
 Referring to FIG. 3, there is illustrated a perspective view of the lid (21) of the invention. The lid (21) also comprises of a base (61) which is circular and planar in fashion. It also has a sidewall (60) that circumferentially surrounds the base (61) of the lid (21) and extends downward from the outer peripheral edge of base (61). Along the upper diameter at approximately the bottom quarter inch of the lid (21) are a set of ridges (40) which allow the lid (21) to twist securely into the bottom (31). The ridges (40) of the lid (21) lock into the ridges (30) of the bottom (31) of can holder (11) which keeps the lid (21) connected.
 In the disclosed embodiment, the lid (21) also contains the first sealing mechanism, a gasket (55) which is a tubular ring made of rubbery material. The gasket (55) is circular in nature and has an opening through the center. It is placed along the outer peripheral edge of the lid (21) surrounding the top of the ridges (40). The gasket (55) provides the means for the present invention to protect and seal in the flavor and moisture of the smokeless tobacco.
 Referring to FIG. 4, the inside of the lid (21) is shown. In the interior of the lid (21), is a medallion (71) made of cork or cork like material. The medallion (71) is also circular and planar in nature and is attached to the base. On the outer rim of the medallion (71), there is another sealing mechanism, a second gasket (62) which is also constructed of rubbery material. The medallion (61) is fixably attached and the gasket (62) is removably attached to the interior of the lid (21). The medallion (71) can also be removably attached to the interior of the lid.
 FIG. 4, shows a cut away view of the medallion (71) surrounded by gasket 62. FIG. 5 shows a cut away view of lid portion (21) illustrating medallion (71) surrounded by gasket 62. Ridges 40 surrounds the exterior surface of the opened top end of lid portion 21. FIG. 6 is a cut away view of bottom portion (31). As illustrated base 10 has a flat surface with internal ridges 30 surrounding the upper opened end of bottom portion (31). A raised portion 35 surrounds the outer peripheral edge of base 10 for supporting the can of smokeless tobacco inserted into can holder (11). FIG. 7 is an exploded view of lid portion (21) illustrating the sealing mechanisms of the can holder (211). medallion 71 overlies the interior surface of base (61) of lid portion (21), first sealing mechanism 62 surround medallion (71) and second sealing mechanism 55 surrounds the peripheral edge of 62.
