         BACKGROUND OF THE INVENTION  
         [0004]    The invention relates to portable adhesive tape dispensers that function as tape protectors, specifically dispensers/protectors that have the ability to be easily carried and readily dispense and sever lengths of tape as needed and to protect the tape roll&#39;s freshly y exposed tape end.  
           [0005]    Adhesive tape such as electrical friction, masking, scotch type and other tapes such as electrical wire marking and security tape are widely used in numerous facets of todays society.  
           [0006]    Originally these tapes were and many are still used without the aid of a dispensing system. In addition, with the exception of medical tapes most tapes lack protective devices and are subject to abrasions and contaminants that can render an entire roll of tape unfit for use. In some cases such as with electrical tape and electrical wire marking tapes abrasions and contaminants can lead to catastrophic failure of the bonding adhesive which can further lead to unintended electrical short circuits and electrical ground faults, thus causing fire, loss of property and life.  
           [0007]    As an improvement inventors have created numerous portable tape dispensers which aid the user in extracting and severing a length of tape. Furthermore, U.S. Pat. No. 4,880,152 to Trankle and U.S. Pat. No. 5,961,066 to Hambleton detail wrist held portable tape dispensers which allow the user to extract and separate a length of tape with one hand while holding an object in the other, possibly to be taped.  
           [0008]    U.S. Pat. No. D 369,385 to Lapointe, U.S. Pat. No. D 428,922 to Packard et al. and U.S. Pat. NO. D 448,416 to Kimura claim tape dispensers that are mostly enclosed providing a good amount of protection to the tape roll.  
           [0009]    U.S. Pat. No. 4,735,351 to Biswas and U.S. Pat. No. 4,252,258 to Plummer detail inventions capable of holding, dispensing, cutting off and holding a tape roll&#39;s tape end ready for the next use. These inventions are also capable of being carried and both are intended to make available multiple tape rolls for use.  
           [0010]    From the body of prior art it is obvious that the inventions designed as wearable tape dispensers do not completely protect the tape products from foreign contaminants and/or abrasions. And those inventions which do completely protect the tape products are not specifically intended to be wearable.  
         BRIEF SUMMARY OF THE INVENTION  
         [0011]    The present invention comprises a device designed for and having the capability to be loaded with one or more rolls of tape which can be easily carried and that can readily dispense and sever lengths of tape as needed.  
           [0012]    The present invention is new and solves a real world need because the above common features are combined with a closure which completely shields the tape product(s), including the tape end(s) from foreign contaminants. In addition the present invention accomplishes these goals without the complicated components found in many of the prior art devices.  
         OBJECTS AND ADVANTAGES  
         [0013]    Accordingly, the objects and advantages of my above titled patent are;  
           [0014]    (a) to provide a tape housing which prevents foreign objects from contaminating housed material(s),  
           [0015]    (b) to provide a tape housing which prevents foreign objects from cutting or abrading a tape roll,
