Bottle containment cap

Abstract

This invention relates to the containment of effervescence in carbonated beverages through the use of a containment cap designed to expel only carbonated liquid and contain the gas within the bottle. The present invention uses an aerosol valve assembly similar to those used to dispense whipped cream from cans.

I claim:

 the tubular valve assembly has the threaded tubular body member, the base end, the top end, the tapered head member and the tapered opening  10 ;  
 the tapered head has the top tapered end, the bottom tapered end and the side end.  
 the inner thread fits on the bottle neck;  
 the inner side fits against and fits against the inside wall of the bottle neck,  
 the inner valve assembly has a stop that will engage when the outer valve assembly is unscrewed to a predetermined limit and further force will engage the stop and causing the inner valve assembly to release at the perforation leaving the lock ring behind on the bottle neck and unscrew from the bottle neck to allow removal of the entire containment cap from the bottle neck;  
 the outer valve assembly having the outer wall, a top wall, the round hole in the center and the inner wall fits over the inner valve assembly,  
 the round hole is tapered downward to a larger diameter and forms a seal with the top tapered end in the closed position;  
 the outer wall has an outer wall thread that engages the outer thread of the inner valve assembly in the closed position;  
 the inner wall has an inner wall thread that engages the threaded tubular body member;  
 the inner wall thread, in the closed position, forces the tubular valve assembly to remain in the sealed position to prevent unintentional leakage of gas;  
 the upper end of the inner wall slides along the inner side of the inner wall assembly and has the step comprising the gasket above the inner wall thread at bottom end to engage and seal the threaded tubular body member against bottom tapered end in the open position;  
 the outer wall thread  11   d  disengages the outer thread In the open position supported by the threaded tubular body member leaving enough freeway space between the inner valve assembly and the outer valve assembly to allow lateral movement of the outer valve assembly sufficient to force open the tubular valve assembly to expel the carbonated liquid when lateral pressure is applied to the outer wall;.  
 the inner wall has indentation the at the lower end comprising the ledge at the bottom of the indentation;  
 the ring fits loosely around the indentation and is allowed to move freely as the bottle is turned upside down to pour;  
 the ring is designed to disengage the tubular valve assembly in the pouring position and allow the tubular valve assembly to open by allowing lateral movement of the tubular valve assembly, and in the upright position of the bottle, the ring engages between the ledge and the inner side forming a stop and prevents the tubular valve assembly from opening by preventing lateral movement;  
 the lower end of the outer side is made in the conventional manner allowing the inner valve assembly to lock on the bottle and is removed by apply excessive force in the counter clockwise direction to separate the containment cap along the perforation;  
 the containment cap is reusable;  
 the outer valve assembly and the inner valve assembly is designed to allow the outer valve assembly to fit in position to the inner valve assembly during the manufacturing process regardless of their tapered features.  
 
     
     
         11 . An containment cap according to  claim 1  comprising:

 said spoke holes are arranged in a circular pattern radiating from the center to fit the angled spokes of the inner valve assembly;  
 said outer staggered threads engage said inner staggered threads in the closed position to seal the containment cap;  
 said angled spokes fit into the corresponding shape of said spoke holes in the closed position to seal the containment cap;  
 in the predetermined open position, said outer valve assembly is rotated clockwise forcing it to slide up said distal slope and come to a rest on said flat top in a predetermined position to engage said outer stop in said stop recess and said outer staggered threads;  
 at this point, downward vertical pressure or lateral pressure on said outer valve assembly will force the valve assembly open causing the carbonated liquid to be expelled;  
 in the open position, the inner staggered threads and the outer staggered threads disengage to allow free vertical movement of the outer valve assembly;  
 additional counter clockwise force will cause the inner valve assembly to release at said perforation and unscrew from the bottle neck to allow removal of the entire containment cap from the bottle neck;  
 in order to allow free vertical movement of said outer valve assembly in the open position, said inner valve assembly has said stop recess which will allow enough freeway space between said inner valve assembly and said outer valve assembly to allow lateral movement of said outer valve assembly sufficient to force open said valve assembly to expel the carbonated liquid when downward vertical pressure or lateral pressure is applied to said outer valve assembly;  
 said safety seal  28  connected to the inner valve assembly will break loose on first opening of the containment cap;  
 said containment cap is removed by apply excessive force in the counter clockwise direction to separate along said perforation leaving said lock ring  26  behind on the bottle neck;  
 once removed, said containment cap is reusable
