Device for pressurizing sparkling wine

Abstract

A closure device for introducing pressurized gas into a sparkling wine bottle. The device includes a cap having two hinged arms for securing the device onto an annular lip at the top of the bottle. A spring biased shaped piston has a plurality of o-ring ribs at the lower end of the piston which are retained at the top of the piston. A one-way valve insert is screwed into the top of the piston. The shaped piston is secured into the neck of the bottle and the device is held in place by the arms. A spring within the cap holds the arms against the bottle. Gas may then be added through the valve.

1 . A sparkling wine closure device configured to allow gas addition comprising:
 a shaped piston having a through bore and an upper shaft and a lower shaft, the lower shafting having a smaller diameter cross section than an upper shaft diameter cross section, the lower shaft having a plurality of slots configured to hold o-rings in a tapering orientation;   a one-way valve secured onto an upper open end of the through bore on the upper shaft of the shaped piston;   an arm cap having two latch arms mounted on a hinge, each latch arm having a curved retaining lip configured to be retained on the annular lip of a sparkling wine bottle opening;   a plate retained at a lower open end of the arm cap, said plate having a center hole through which the shaped piston may be fitted and secured; and   a spring retained within an interior of the arm cap between the plate and a cap top of the arm cap.   
   
   
       2 . The device of  claim 1 , wherein said one way valve is a Schrader valve. 
   
   
       3 . The device of  claim 1 , wherein said shaped piston has two side facets on opposing sides at an upper portion of said shaped piston. 
   
   
       4 . The device of  claim 1 , wherein said one way valve includes a valve cap. 
   
   
       5 . The device of  claim 1 , wherein the plurality of slots includes three slots. 
   
   
       6 . The device of  claim 1 , wherein said plate is retained against said shaped piston using a locking washer. 
   
   
       7 . The device of  claim 1 , wherein said plurality of slots have equal width dimensions, but unequal depth dimensions, wherein an upper slot is less deep than a lower slot.
