     Operation and Control Procedure 
     The user first places the drink container on a table or in the left hand, unscrews and removes the moistureproof cover  1 , and then the moistureproof cover closing ring  3  under the moistureproof cover  1  will be torn from the moistureproof cover  1 . Remove the moistureproof cover  1 , hold the handle of the device cover closing ring having a handle  16  and tear out the device cover closing ring having a handle  16 . Hold the device cover screwing sleeve  18  outside the device cover  4 , screw down the device cover  4  to the lower limit, and then remove the device cover screwing sleeve  18 . 
     Accordingly, the device cover opening thimble  7 , which has been screwed to the lower limit, breaks the coniform film sealing layer having the fragile groove  26 . The drink inside the container body  35  flows into the bottom of the device cover chamber  9  via the lateral channel  39  and the device cover opening thimble drink channel  8 , contacts and has continuous effervescent decomposed reaction with the effervescent decomposed plug  20 , so as to decompose the effervescent decomposed plug  20  into CO 2  gas and liquid from bottom to top, wherein after the effervescent decomposed plug  20  is totally decomposed, the drink inside the container body  35  flows into the device cover chamber  9  via the lateral channel  39  and the device cover opening thimble drink channel  8  under pressure, and then spouts out of the container via the device cover central cylinder drink channel  11  communicated with the device cover chamber  9  and the device cover drink nozzle  12  at a high speed. 
     The spouting drink to the air will fall back into the central concave structure of the container cover having a concave central portion  29  after reaching the apogee. And the drink will stop spouting when the pressure is balanced inside and outside the container, and the spouting drink to the air falls back into the central concave structure of the container cover having a concave central portion  29 . 
     Now the user can enjoy the drink falling back in two ways. The first way is picking up the container directly and drinking from an edge of the container cover having a concave central portion  29 , just like ordinary cups, which is adapted for enjoying the drink alone. The second way is pouring the drink falling back into other cups to share, which is adapted for enjoying the drink with others. 
     It is worth mentioning that, either in the first or the second way, the moistureproof cover  1  should be screwed up to the device cover  4  again before pouring the drink into other cups, so as to prevent the drink from flowing out from the device cover drink nozzle  12  when pouring or drinking the drink. After drinking up the drink falling back, the user also has two choices for the rest drink. The first choice is sucking from the device cover drink nozzle  12  directly, and the second choice is holding the handle of the closing ring having a handle of the container cover having the concave central portion  34 , tearing the closing ring having a handle of the container cover having the concave central portion  34 , unscrewing and removing the container cover having a concave central portion  29  and drinking from the edge of the container, like ordinary cups, which is adapted for enjoying the drink alone. If several people share the drink, the drink can be poured out to other cups. 
     When the container cover having a concave central portion  29  and the sealing cover  22  is formed integrally, the above operation and control procedure do not change. 
     When the coniform film sealing layer having the fragile groove  26  and the device cover opening thimble  7  are replaced by the device cover crew-cut piston thimble  40  and the piston  43 , the above operation and control procedure do not change. 
     When the coniform film sealing layer having the fragile groove  26  and the device cover opening thimble  7  are replaced by the device cover crew-cut opening head  45 , the above operation and control procedure do not change. 
     When the screen  10  and the device cover  4  are formed integrally, the above operation and control procedure do not change. 
     When the multi-layers annular ridge sealing sleeve  21  and the device cover  4  are formed integrally, the above operation and control procedure do not change. 
     When the container is a barrel having a valve assembled outside a bottom thereof, the goods of this package are ordinarily liquor of  5  liter, especially beer, champagne, foam liquor, or carbonated drinks containing gas. The user should place the container on the table, unscrew and remove the moistureproof cover  1 , and then the moistureproof cover closing ring  3  under the moistureproof cover  1  will be torn from the moistureproof cover  1 . Remove the moistureproof cover  1 , hold the handle of the device cover closing ring having a handle  16  and tear out the device cover closing ring having a handle  16 . Hold the device cover screwing sleeve  18  outside the device cover  4 , screw down the device cover  4  to the lower limit, and then remove the device cover screwing sleeve  18 . 
     Accordingly, the device cover opening thimble  7 , which has been screwed to the lower limit, evenly breaks the coniform film sealing layer having the fragile groove  26 . The drink inside the container body  35  flows into the bottom of the device cover chamber  9  via the lateral channel  39  and the device cover opening thimble drink channel  8 , contacts and has continuous effervescent decomposed reaction with the effervescent decomposed plug  20 , so as to decompose the effervescent decomposed plug  20  into CO 2  gas and liquid from bottom to top, wherein after the effervescent decomposed plug  20  is totally decomposed, the drink inside the container body  35  flows into the device cover chamber  9  via the lateral channel  39  and the device cover opening thimble drink channel  8  under pressure, and then spouts out of the container via the device cover central cylinder drink channel  11  communicated with the device cover chamber  9  and the device cover drink nozzle  12  at a high speed. 
     The spouting drink to the air will fall back into the central concave structure of the container cover having a concave central portion  29  after reaching the apogee. And the drink will stop spouting when the pressure is balanced inside and outside the container, and the spouting drink to the air falls back into the central concave structure of the container cover having a concave central portion  29 . The moistureproof cover  1  should be screwed up to the device cover  4  before pouring the drink into other cups, so as to prevent the drink from flowing out from the device cover drink nozzle  12  when pouring the drink into other cups. After pouring the drink falling back, the user can open the valve to let out the liquor or drink in the container into other cups to share. 
     When the container is the conventional drink container having an opening of screw thread  49 , it is a special operation manner. In some circumstances, the users do not want to collect the spouting drink out, they only need the spouting manner and joy effect. A preferred drink is carbonated drink. 
     The user unscrews and removes the moistureproof cover  1 , wherein the moistureproof cover closing ring  3  under the moistureproof cover  1  will be torn from the moistureproof cover  1 , and then removes the moistureproof cover  1 . After the user holds the handle of the device cover closing ring having a handle  16  and tear out the device cover closing ring having a handle  16 , for better spouting effect, the user can shake the container acutely, so that CO 2  in the carbonated drink releases within the container as much as possible to increase pressure inside the container. Afterwards, the user can hold the device cover screwing sleeve  18  outside the device cover  4 , screw down the device cover  4  to the lower limit, and then remove the device cover screwing sleeve  18 . 
     Accordingly, the device cover opening thimble  7 , which has been screwed to the lower limit, evenly breaks the coniform film sealing layer having the fragile groove  26 . The drink inside the container body  35  flows into the bottom of the device cover chamber  9  via the device cover opening thimble drink channel  8 , contacts and has continuous effervescent decomposed reaction with the effervescent decomposed plug  20 , so as to decompose the effervescent decomposed plug  20  into CO 2  gas and liquid from bottom to top, wherein after the effervescent decomposed plug  20  is totally decomposed, the drink inside the container body  35  flows into the device cover chamber  9  via the device cover opening thimble drink channel  8  under pressure, and then spouts out of the container via the device cover central cylinder drink channel  11  communicated with the device cover chamber  9  and the device cover drink nozzle  12  at a high speed. The drink stops spouting when the pressure is balanced inside and outside the container. After spouting drink stops, if the user wants to drink the rest drink in the container, the user can drink from the device cover drink nozzle  12  directly, and can also drink from the container opening  36  by unscrewing the sealing cover  22  and removing the entire control device of spouting drink.
