BACKGROUND OF THE PRESENT INVENTION-  1. Field of Invention 
-  The present invention relates to a grip, and more particularly to a disposable handle bar gripping arrangement which is adapted for detachably wrapping a handle bar for preventing unwanted substances, such as dirt and germs, from contacting with a user who needs to grip on the handle bar. 
-  2. Description of Related Arts 
-  A conventional gripping bar, such as a handle bar for a shopping cart, usually comprises an elongated main body which forms part of a lager structure for a user to grip thereon. For example, for a typical user of a shopping cart, a user is able to grip on the shopping cart and push the cart to whatever destination the user desires. 
-  Alternatively, a handle bar installed on public transport, such as a handrail installed in a bus, is designed for passengers to hold on it so that when the bus moves, the passengers are able to balance themselves while standing or sitting in the bus. This kind of handle bar has widely been utilized in many occasions. 
-  A major problem for these conventional handle bars is that since they are designed for public use, it is extremely easy for them to come into contact with such unwanted substances as dirt or contaminated residuals. As a result, when subsequent users come to grip on the handle bar, their hands will come into contact with such unwanted substances. As a result, handle bars may become the medium for causing poor public hygiene or even transmitting infectious diseases. 
-  These consequences may become more adverse when one takes into account the fact that in many stores where shopping carts are extensively utilized, there exist a large number of infants or children who are intentionally placed on the shopping carts by their parents. Their reason is obvious, but given the poor hygiene condition of the handle bars, those infants or children are at high risk of contacting those contaminated or infectious substances. 
-  In particular, in those areas where highly infectious diseases are prevalent, handle bars can become a significant source of medium for communicating diseases. For example, SARS and bird flu can be communicated easily by handle bars. 
SUMMARY OF THE PRESENT INVENTION-  A main object of the present invention is to provide a disposable handle bar gripping arrangement which is adapted for enclosing a handle bar for preventing unwanted substances, such as dirt, from contacting with a user who needs to grip on the handle bar. 
-  Another object of the present invention is to provide a disposable handle bar gripping arrangement which is made of durable and germ-resistant materials for effectively isolating unwanted substances on the handle bar from user's hands.
