Venting bottle closure

Abstract

A closure assembly which comprises an orifice which comprises a venting material, and wherein said venting material is substantially permeable to gases and wherein said venting material is substantially impermeable to liquids.

1 . A closure assembly comprising a base, wherein said base comprises at least one orifice which comprises a venting material, and wherein said venting material is substantially gas-permeable and wherein said venting material is substantially liquid-impermeable.  
   
   
       2 . A closure assembly according to  claim 1 , further comprising a lid.  
   
   
       3 . A lid according to  claim 2 , wherein said lid comprises a sealing means which is operable to seal said orifice.  
   
   
       4 . A lid according to  claim 3 , wherein said sealing means extends through said venting material when said lid is in the closed position.  
   
   
       5 . A closure assembly according to  claim 1 , wherein said venting material is selected from the group consisting of a woven or non-woven fabric, polyethylene, polypropylene, mylar, and polytetrafluoroethylene.  
   
   
       6 . A method of venting gases comprising the steps of filling a container with a composition, expelling gases through a venting material, and sealing the closure after headspace is eliminated.  
   
   
       7 . A method of venting gases with the closure assembly of  claim 1  comprising the steps of: 
 a) affixing said closure assembly to a container,    b) increasing internal pressure inside of the container to expel gases through said orifice, and    c) sealing said orifice after gas is expelled.    
   
   
       8 . A method of venting gases with the closure assembly of  claim 1  comprising the steps of: 
 a) affixing the closure assembly to a container,    b) decreasing atmospheric pressure outside of the container to expel gases through said orifice, and    c) sealing said orifice after gas is expelled.
