   BACKGROUND OF THE INVENTION 
   1) Field of the Invention 
   The present invention relates to a device that provides for advertising, display of information, personalized messages, and the like. In addition, the device contains flexible walls that contain such information and can be inflated and deflated. More particularly, the device may be attached to any shaft-like object. In preferred embodiments, the device will be attached to a writing instrument that is capable of use for writing. 
   2). Description of the Related Art Including Information Disclosed Under 37 CFR 1.97 and 1.98 
   For being attractive or displaying a message, a writing instrument is usually decorated with patterns or messages on the barrel or writing instrument cap. The barrel of a writing instrument usually has a rigid surface for the convenience of being held and for containing the writing instrument&#39;s internal mechanical parts. Therefore, the surface of a writing instrument can be decorated with only planar or nearly planar patterns. 
   The planar pattern on a writing instrument is not particularly eye-catching. Therefore, it is preferable to have a 3-dimensional pattern on a writing instrument. One solution is to attach an inflatable unit at the tail end of the barrel, i.e. the non-writing end. The inflatable unit would contain the information, personalized messages, and the like and display the same when inflated. The inflatable unit may also be attached to the end of any shaft-like instrument. 
   It is therefore an object of the present invention to provide an improved inflatable display device that may be attached to a writing instrument, cake topper or any other shaft-like object. 
   BRIEF SUMMARY OF THE INVENTION 
   The present invention is an improved inflatable display device that provides for advertising, displaying information or personalized messages, and the like. In addition, the device contains flexible walls that contain such information and can be inflated and deflated. 
   The device includes a hollow sleeve having an open top, a sidewall with at least one air hole therein, and an open bottom. The hollow sleeve is placed within a balloon having an open top and an open bottom, wherein seals are formed between the top of the sleeve and the top of the balloon and between the bottom of the sleeve and the bottom of the balloon. Located at the bottom of the sleeve is a junction configured to form a seal at the bottom of the sleeve. Located at the top of the sleeve is a valve assembly configured so that when closed it forms a seal at the top of the sleeve and when opened air can either be forced through the valve assembly and into the sleeve forcing the balloon to expand or it can be forced out of the sleeve and through the valve assembly allowing the balloon to contract. 
   In preferred embodiments, either a writing instrument or any shaft-like object can be attached to the junction at the bottom of the sleeve. In another preferred embodiment, the balloon can be configured to form three dimensional images of various shapes and sizes.

   DETAILED DESCRIPTION OF THE INVENTION 
   The present invention relates to a device that provides for advertising, display of information, personalized messages, and the like. In all embodiments of the invention, the device contains flexible walls that contain such information and can be inflated and deflated. The device may be attached to any shaft-like object, including a writing instrument that is capable of use for writing. 
     FIG. 1  is an orthogonal schematic side view of the inflatable display device  15  while  FIG. 2  is an exploded orthogonal schematic cross-sectional side view of the inflatable display device  15  showing the relational arrangement of the components. Referring to  FIGS. 1 and 2 , the inflatable display device  15  consists of a junction  1  molded from plastic with threads at its tail end to allow attachment to any shaft-like instrument, which is not shown. Alternatively, any other form of attaching means may be utilized, such as the materials being force fitted, snapped together, glued, etc. 
   The balloon  2  is made from any elastic, synthetic material such as rubber or latex. The sleeve  4  is formed of metal, molded plastic or any other suitable material and is inserted and centered within the balloon  2 . The lower end of the balloon  2  is pinched tightly between junction  1  and the sleeve  4  to form a seal, while the upper end of the balloon  2  is pinched tightly between the tail  6  and the sleeve  4  to form a seal. The tail  6  is also formed of metal, molded plastic or any other suitable material. The spring  3  fits within the sleeve  4  with its lower end engaging junction  1  and its upper end engaging valve  5  and forcing it against the tail  6  creating an air tight seal. The air inlet  7  is slidably coupled to the tail  6 . When the air inlet  7  is depressed, it causes the spring  3  to depress and the air tight seal between valve  5  and tail  6  to be broken, allowing the balloon  2  to be inflated or deflated. 
     FIG. 3A  is an orthogonal side view of the inflatable display device  15  in an uninflated condition while  FIG. 3B  is an orthogonal schematic cross-sectional side view of the inflatable display device  15  in an uninflated condition. The air inlet  7  contains an air inlet hole  7   a  and sleeve  4  contains air holes  4   a  and  4   b . The air holes may be of any number, shape or size. Also, the balloon  2  is placed around the sleeve  4  and is sealed at the lower and upper ends, as previously described. These figures show the upper end of spring  3  engaged with and forcing valve  5  against the tail  6  creating an air tight seal. 
     FIG. 4A  is an orthogonal side view of the inflatable display device  15  in a semi-inflated condition while  FIG. 4B  is an orthogonal schematic cross-sectional side view of the inflatable display device  15  in a semi-inflated condition. These figures show the air inlet  7  in a depressed state, which allows air to be either blown by mouth or mechanically pumped through the air inlet hole  7   a . Depressing air inlet  7  also opens valve  5  and allows air to travel between valve  5  and tail  6  and into the central portion of sleeve  4 . The air then travels through air holes  4   a  and  4   b  forcing the balloon  2  to expand. 
     FIG. 5A  is an orthogonal side view of the inflatable display device  15  in an inflated condition while  FIG. 5B  is an orthogonal schematic cross-sectional side view of the inflatable display device  15  in an inflated condition. These figures depict the balloon  2  in a fully inflated condition and the upper end of spring  3  engaged with and forcing valve  5  against the tail  6  creating an air tight seal. 
   One embodiment of the present invention is depicted in  FIG. 6 . This is an orthogonal schematic side view of the inflatable display device  15  on a writing instrument according to the present invention. The junction  1  is attached to the barrel  8  of a pen or any other writing instrument. The writing instrument portion is found in the prior art and would typically comprise a tip cone  10  fastened to the barrel  8 , which in turn houses a pen spring  11 , a refill  12  and a turning mechanism  13 . 
   Another embodiment of the present invention is shown in  FIG. 7 . This is an orthogonal schematic side view of the inflatable display device on a shaft-like object. In this embodiment, the junction  1  is attached to a shaft-like attachment  9 . 
   While the invention has been described in combination with embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art in light of the foregoing teachings. Accordingly, the invention is intended to embrace all such alternatives, modifications and variations as fall within the spirit and scope of the appended claims.
