Vented bottle

Abstract

Described is a bottle having a cap with an atmospheric venting means comprising a venting receptacle and a porous thermoplastic plug. The porous plug can be held in place with a retaining ring.

1 . A bottle comprising:
 a container having a threaded neck; and   a dispensing closure having a base member, a cap, and a hinge connecting the base member and the cap, wherein the base member comprises a threaded skirt member and a deck member wherein the deck member comprises a spout,   wherein the cap has an outer wall and a top surface having an cylindrical venting receptacle, the venting receptacle having at least one small orifice fluidly attached to the top surface and a larger orifice at the opposite end wherein the venting receptacle holds a porous thermoplastic plug.   
     
     
         2 . The bottle of  claim 1 , wherein the porous thermoplastic plug is molded, open-celled polyethylene having a nominal pore size of 1 micron to 25 microns. 
     
     
         3 . The bottle of  claim 1 , wherein the porous thermoplastic plug is compressible. 
     
     
         4 . The bottle of  claim 1 , wherein the venting receptacle contains a retaining ring. 
     
     
         5 . The bottle of  claim 4 , wherein the thermoplastic plug is inserted past the retaining ring. 
     
     
         6 . The bottle of  claim 4 , wherein the thermoplastic plug is compressed by the retaining ring. 
     
     
         7 . The bottle of  claim 1 , wherein the thermoplastic plug extends beyond the venting receptacle larger orifice. 
     
     
         8 . The bottle of  claim 7 , wherein the thermoplastic plug has curved ends. 
     
     
         9 . The bottle of  claim 1 , wherein the cap outer wall has an interior surface and the interior surface within the venting receptacle has one or more ribs to abut the thermoplastic plug. 
     
     
         10 . A bottle comprising:
 a container having a threaded neck and a pour spout; and   a dispensing closure having a cap with a cap top surface and a threaded skirt member, wherein the cap top surface has a venting receptacle, the venting receptacle containing a porous thermoplastic plug.   
     
     
         11 . The bottle of  claim 10 , wherein the porous thermoplastic plug is molded, open-celled polyethylene having a nominal pore size of 1 micron to 25 microns. 
     
     
         12 . The bottle of  claim 10 , wherein the porous thermoplastic plug is compressible. 
     
     
         13 . The bottle of  claim 10 , wherein the venting receptacle contains a retaining ring. 
     
     
         14 . The bottle of  claim 10 , wherein the thermoplastic plug extends beyond the venting receptacle larger orifice. 
     
     
         15 . The bottle of  claim 14 , wherein the thermoplastic plug has curved ends. 
     
     
         16 . A bottle comprising:
 a container having a neck; and   a dispensing closure comprising a cap,   wherein the cap has an outer wall and a top surface having an venting receptacle, the venting receptacle having at least one small orifice fluidly attached to the top surface and a larger orifice at the opposite end, wherein the venting receptacle holds a porous thermoplastic plug.   
     
     
         17 . The bottle of  claim 16 , wherein the porous thermoplastic plug is molded, open-celled polyethylene having a nominal pore size of 1 micron to 25 microns. 
     
     
         18 . The bottle of  claim 16 , wherein the venting receptacle contains a retaining ring. 
     
     
         19 . The bottle of  claim 16 , wherein the thermoplastic plug extends beyond the venting receptacle larger orifice. 
     
     
         20 . The bottle of  claim 16 , wherein the thermoplastic plug has curved ends.
