Title: High-pressure steel bottle sealing structure

Description:
BACKGROUND OF THE INVENTION  
      1. Field of the Invention  
      The present invention relates to an improvement of a high-pressure steel bottle sealing structure, especially one improving a high-pressure steel bottle sealing structure with a fast air-filling completed sealing procedure.  
      2. Description of the Related Art  
      Commonly high-pressure steel bottle sealing structures mainly comprises of a hat covering structure directly welded to the steel bottle and an oil-sealing cover matched with an oil leak-proof or an O-Ring sealing structure stamped and filled into the steel bottle.  
      Therefore, much improvement is needed in the above-mentioned commonly used high-pressure steel bottle sealing structures in order to obtain a disposable high-pressure steel bottle with a low capital cost and high manufacturing quantity for more economical efficiency.  
     SUMMARY OF THE INVENTION  
      The present invention relates to an improvement of a high-pressure steel bottle sealing structure mainly consisting of a cover body, a rubber ring and a bottle head whereby the cover body is designed with a convex point at the horizontal bottom which diameter is smaller than that of the inner diameter of the bottle head, and a rubber ring is found at the vertical side edge of the cover body with a thinner diameter than that of the horizontal bottom.  
      The present invention relates to an improvement of a high-pressure steel bottle sealing structure mainly consisting of a cover body, a rubber ring and a bottle head whereby the rubber ring is found at the vertical side edge of the cover body stopping at the air passage in order to resist inverse pressure and to prevent air leaking.  
      The present invention relates to an improvement of a high-pressure steel bottle sealing structure mainly consisting of a cover body, a rubber ring and a bottle head whereby the bottle head is found at the top of the high-pressure steel bottle and a ring base is designed in the middle of the passage such that the cover body inside stops at the ring base by using the convex point, and an additional length is also left at the bottle head for sealing procedure.

     DETAILED DESCRIPTION OF THE INVENTION  
      The present invention of a high-pressure steel bottle can be used in food processing such as butter processed into a foam for convenient use in butter foam coffee, or butter processed into a paste for use in cake decorations. Hence, apart from requesting pureness of gas in the steel bottle, stable pressure is also important in order to attain a rapid and effective purpose.  
      With reference to  FIG. 1  showing a combination of the high-pressure steel bottle sealing structure, the sealing structure of the high-pressure steel bottle  10  mainly consisting of a cover body  11 , a rubber ring  12  and a bottle head  13  is shown in the two diagrams in different angles. The horizontal bottom  14  of the cover body  11  is designed with a convex point  15  stopping at the ring base  16  found at the middle of the passage of the bottle head  13 .  
      With reference to  FIG. 2  showing a plan of the present invention before sealing procedure, high-pressure gas  17  goes through the cover body  11  of the bottle head  13  containing rubber ring  12  into the air passage in-between to the steel bottle  10  which is than immediately sealed.  
      With reference to  FIG. 3  showing a plan of the present invention after sealing procedure, the top of the bottle head  13  is curved inwardly to the top of the vertical side edge  18  of the cover body  11 . The rubber ring  12  is compressed in-between the horizontal bottom  14  and the top of bottle head  13  and fills the air passage thus avoiding air-leaking and inverse flow of high-pressure gas  17 .  
      With reference to  FIG. 4  showing a plan of the high-pressure steel bottle, the high-pressure steel bottle  10  is a finished product containing high-pressure gas  17  and will not leak through bottle head  13  or cover body  11  before use. Hence, the present invention provides a very rapid sealing procedure of N 2 O, O 2  or other special gas.
