CROSS-REFERENCE TO RELATED APPLICATIONS  
       [0001]     The present application is a Continuation-In-Part of U.S. patent application Ser. No. 09/992,958 filed Nov. 26, 2001 which claims priority based on Provisional Application Ser. No. 60/252,602 filed Nov. 24, 2000 which is incorporated herein by reference. 
     
    
     TECHNICAL FIELD  
       [0002]     The present invention relates to the field of refrigerant storage tank labeling systems and more particularly to a system for labeling refrigerant storage tanks.  
       BACKGROUND INFORMATION  
       [0003]     Refrigerant storage tanks can be filled with any number of gasses or liquids. Many of these substances are harmful to animals and the environment. There is currently no standard color or shape of refrigerant storage tanks that impart the substance contained inside.  
         [0004]     Thus, it is imperative to label the storage tank and identify its contents. However, any given storage tank can contain a number of different substances throughout its lifetime. Therefore, a labeling system capable of easy removal is imperative to avoid confusion and potentially deadly hazards.  
         [0005]     Accordingly, there is a need for a removable refrigerant tank labeling system capable of modifications and that imparts to the user the exact contents of the refrigerant storage tank.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0017]     Referring to  FIG. 1 , a front view of the refrigerant labeling system  10  is shown. The system  10  includes a refrigerant tank  12  and a sleeve  14 . The refrigerant tank  12  can be any size or shape and the sleeve  14  has a shape that is complementary to the tank  12 . The refrigerant storage tank  12  is any refrigerant storage tank known in the art.  
         [0018]     In the preferred embodiment, the sleeve  14  is tubular and is made from Linear Low Density Polyethylene (“LLDPE”). The sleeve  14  fits tightly around at least part of the refrigerant tank  12 . The sleeve  14  maintains its position on the tank  14  because it fits tightly about the tank  12 . The sleeve  14  is not glued onto the tank  12  or otherwise permanently attached.  
         [0019]     Although in the preferred embodiment, the sleeve  14  covers only the center of the tank  12 , in other embodiments, the sleeve  14  covers more of the tank  12 . The invention contemplates where the sleeve  12  covers any portion of the tank  12  as long as it covers some portion of the tank.  
         [0020]     The sleeve  14  is placed onto the tank  12  by opening the sleeve  14  such that the tubular structure is apparent, then either slipping the sleeve  14  over the top of the tank  12  or up from the bottom of the tank  12 . In the preferred embodiment, the sleeve  14  is dimensioned such that it will fit very tightly over the tank  12 . Once the sleeve  14  is placed onto the tank  12 , it will remain in position until a user removes the sleeve  14 .  
         [0021]     Referring next to  FIG. 2 , the sleeve  14  is tubular. In the preferred embodiment, the sleeve  14  is one continuous tube, i.e., there is no seem. This design makes the sleeve  14  very strong and allows the sleeve  14  to be placed onto the tank in the manner described above. Referring next to  FIG. 3 , an alternate embodiment of the sleeve  26  is shown. In this embodiment, the sleeve  26  is not one continuous tube, but rather, a sheet that is wrapped around a tank, wrapped over itself at least partially, and then fastened together. Thus, two ends of the sleeve  26  attach to form the tubular structure. The sleeve does not attach to the tank. The two sides of the sleeve are attached either by an adhesive being located on the sleeve itself and pressure sensitive, or an adhesive having an adhesive protective sheet, and the protective sheet being removed, allows for adhesion of the two sides. In other embodiments, any method known in the art of adhering or attaching to sides of LLDPE can be used. This creates the same effect as the tubular sleeve shown in  FIG. 2 , however, the sleeve  26  requires the additional step of adhering or fastening the sheet together. In the preferred embodiment, shown in  FIG. 2 , fastening, adhering nor attaching of any kind is required. In the preferred embodiment shown in  FIG. 2 , the sleeve  14  is pulled onto the tank and remains there without any additional user intervention.  
         [0022]     Still referring to  FIGS. 2 and 3 , the sleeve  14 ,  26  is placed onto the tank and maintains its position on the tank. Thus, the sleeve  14 ,  26  does not require any additional attachment to the tank. Rather, the dimensions and the material of the sleeve  14 ,  26  inherently allow the sleeve  14 ,  26  to maintain its position on the tank.  
         [0023]     Still referring to  FIGS. 2 and 3 , the sleeve  14  can be placed onto a refrigerant tank at any time. However, for safety reasons, it is most desirous to place the sleeve  14  onto the refrigerant tank while the tank is empty and before the refrigerant is added. Thus, to label the refrigerant tank with the intended contents prior to the contents being added.  
         [0024]     Still referring to both  FIGS. 2 and 3 , the sleeve  14 ,  26  has at least one writeable portion of a predetermined size. In the preferred embodiment, the sleeve  14 ,  26  has at least two writable portions  16 ,  18 . These areas allow the easy adhesion of typical inks used in the art. The writeable portions  16 ,  18  can be used to place any indicia. In the preferred embodiment, the writeable portions  16 ,  18  specifically queries the user to include information regarding the downstream user or “customer”. Additionally, typical or commonly used refrigerants are pre-printed on the writable portion having a check box directly next to the refrigerant. This allows for the user to simply check the appropriate box to indicate the contents of the tank.  
         [0025]     The preferred embodiment additionally includes writeable portion  22 , pre-printed with a “#” sign. This area is intended to include a number, which will be written by a user.  
         [0026]     In the preferred embodiment, the sleeve  14 ,  26  includes a bar code area  24 . This is for electronic identification of the tank system. The bar code used can be any of those known and used in the art. Also included in the preferred embodiment is a standard chemical hazard indication  20 . Using the standard signage known and used in the art, this will indicate to the handler whether the contents of the tank are, for example, flammable, non-flammable, hazardous, non-hazardous, or any other indication known and used in the art.  
         [0027]     In practice, the present system is used for labeling the refrigerant storage tank with information necessary for the safe handling and identification of the tank. Once the tank is emptied, the sleeve is easily removed and a new sleeve is introduced to the system. This allows for an easy change of the refrigerant contents inside the tank and ensures proper labeling of this change. Additionally, since the sleeve does not permanently attach to the tank, the sleeve is able to be completely removed, thus leaving no chance of incorrect or obsolete refrigerant contents information on the tank.  
         [0028]     Although certain indicia has been described as being included on the sleeve, the invention is not limited to this indicia. Any indicia useful and deemed necessary or useful by any user can be included on the sleeve of the invention.  
         [0029]     While the principles of the invention have been described herein, it is to be understood by those skilled in the art that this description is made only by way of example and not as a limitation as to the scope of the invention. Other embodiments are contemplated within the scope of the present invention in addition to the exemplary embodiments shown and described herein. Modifications and substitutions by one of ordinary skill in the art are considered to be within the scope of the present invention, which is not to be limited except by the following claims.
