Launcher closure with bearing retainer and pressure pulse operation

Abstract

The launcher closure with outer cover is adapted to fit on a canister that contains a missile or the like thereby sealing the inside of the canister from the external environment and allowing the missile to be tested. The closure is designed to move only in the event of a fast rise in pressure caused by launch, but to remain in place in the occurrence of a slow pressure leak. The closure is in a predetermined shape such as a cylinder or the like with one end of the tube containing an O-ring to seal the canister and closure, and the other end of the closure with a surface. The closure, when attached to the canister, seals the inside of the canister from the external environment.

What is claimed is:  
     
         1 . An apparatus for connecting a cap to a container comprising: 
 a cap wherein at least one protrusion is disposed in a radial direction to said cap;    wherein said cap has a pressure sensitive system; and    wherein said pressure sensitive system is operatively coupled to said at least one protrusion.    
     
     
         2 . The apparatus, as claimed in  claim 1 , wherein the cap forms a seal within a canister.  
     
     
         3 . The apparatus, as claimed in  claim 1 , wherein at least one protrusion is operatively coupled to an outside surface of a canister.  
     
     
         4 . The apparatus, as claimed in  claim 1 , wherein at least one protrusion is operatively coupled to an inside surface of a canister.  
     
     
         5 . An apparatus which covers an opening of an elongated canister wherein the canister has at least one open end comprising: 
 an inner cover having two ends wherein said first end is enclosed;    an outer cover having two ends wherein said first end is enclosed and in between said first end and said second end is a surface having at least one hole;    wherein at least one protrusions protrude out from the at least one hole; and    wherein said inner cover and said outer cover are operatively coupled to each other.    
     
     
         6 . The apparatus, as claimed in  claim 5 , wherein said outer cover has a recessed groove.  
     
     
         7 . The apparatus, as claimed in  claim 6 , wherein contained in said recessed groove is an O-ring.  
     
     
         8 . The apparatus, as claimed in  claim 5 , wherein at least one protrusion is operatively coupled to an outside surface of a canister.  
     
     
         9 . The apparatus, as claimed in  claim 5 , wherein at least one protrusion is operatively coupled to an inside surface of a canister.  
     
     
         10 . The apparatus, as claimed in  claim 5 , wherein a spring operatively couples said outer cover to said inner cover.  
     
     
         11 . The apparatus, as claimed in  claim 5 , wherein the plurality of protrusions is operatively coupled to an inside surface of the first end of the canister.  
     
     
         12 . The apparatus, as claimed in  claim 5 , wherein at least one protrusion is at least one ball bearing.  
     
     
         13 . The apparatus, as claimed in  claim 12 , wherein an edge of said inner cover substantially presses against said at least one ball bearing.
