Dual orifice venting bottle closure

Abstract

A closure assembly, wherein said closure assembly comprises at least a first and a second orifice, wherein said second orifice 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 a first and a second orifice, wherein said second orifice 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, wherein said lid comprises a first and second closure portion.  
   
   
       3 . A closure assembly according to  claim 2 , wherein said first and second closure portions are physically connected by a bending means.  
   
   
       4 . A lid according to  claim 2 , wherein said first closure portion further comprises a sealing means which is operable to seal said first orifice.  
   
   
       5 . A lid according to  claim 2 , wherein said second closure portion further comprising a sealing means which is operable to seal said second orifice.  
   
   
       6 . 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.  
   
   
       7 . A method of venting gases comprising the steps of filling a container with a composition, expelling gases through a venting material, and sealing the orifice after headspace is eliminated.  
   
   
       8 . A method of venting gases with the closure assembly of  claim 1  comprising the steps of: 
 a) filling a container with a composition,    b) affixing the closure assembly to the container,    c) sealing the first orifice,    d) increasing internal pressure inside of the container to expel gases through the second orifice, and    e) sealing the second orifice after gas is expelled.    
   
   
       9 . A method of venting gases with the closure assembly of  claim 1  comprising the steps of: 
 a) filling a container with a composition,    b) affixing the closure assembly to the container,    c) sealing the first orifice,    d) decreasing atmospheric pressure outside of the container to expel gases through the second orifice, and    e) sealing the second orifice after gas is expelled.
