Sampling port system

Abstract

A sampling port system for providing a self-sealing access port for the extraction of liquid or gas samples from a container. The sampling port system includes a housing having a threaded lumen, at least one sealing structure threadably positionable within the threaded lumen, and a plug threadably positionable within the threaded lumen above the sealing structure. The housing is preferably positioned within an existing threaded port within the container.

I claim:  
     
         1 . A sampling port system, comprising: 
 a housing having an upper opening, a threaded lumen, a floor, and a lower aperture within said floor; and    at least one sealing structure threadably positioned within said threaded lumen, wherein said at least one sealing structure is able to self-seal after the withdrawal of a narrow object.    
     
     
         2 . The sampling port system of  claim 1 , including a plug threadably positioned within said threaded lumen above said at least one sealing structure.  
     
     
         3 . The sampling port system of  claim 2 , wherein said plug includes an engaging cavity.  
     
     
         4 . The sampling port system of  claim 1 , including at least one septum within positioned beneath said at least one sealing structure.  
     
     
         5 . The sampling port system of  claim 4 , wherein said at least one septum is comprised of a resilient and sealing material.  
     
     
         6 . The sampling port system of  claim 5 , wherein said septum is comprised of a rubber material.  
     
     
         7 . The sampling port system of  claim 6 , wherein said at least one sealing structure includes at least one groove for allowing manipulation of said at least one sealing structure.  
     
     
         8 . The sampling port system of  claim 6 , wherein said at least one sealing structure includes at least one engaging cavity for allowing manipulation of said at least one sealing structure.  
     
     
         9 . The sampling port system of  claim 8 , wherein said at least one sealing structure includes a concentric aperture.  
     
     
         10 . The sampling port system of  claim 1 , wherein said at least one sealing structure includes a concentric aperture.  
     
     
         11 . The sampling port system of  claim 1 , including a means for securing said housing within said container.  
     
     
         12 . The sampling port system of  claim 1 , including a plug threadably positioned within said threaded lumen above said at least one sealing structure.  
     
     
         13 . The sampling port system of  claim 12 , wherein said plug includes an engaging cavity.  
     
     
         14 . The sampling port system of  claim 11 , wherein said at least one sealing structure is comprised of an outer rigid structure threadably engaged within said threaded lumen and a septum positioned beneath said at least one sealing structure.  
     
     
         15 . The sampling port system of  claim 14 , wherein said septum is comprised of a resilient and sealing material.  
     
     
         16 . The sampling port system of  claim 15 , wherein said septum is comprised of a rubber material.  
     
     
         17 . The sampling port system of  claim 16 , wherein said outer rigid structure includes at least one groove for allowing manipulation of said at least one sealing structure.  
     
     
         18 . The sampling port system of  claim 16 , wherein said at least one sealing structure includes at least one engaging cavity for allowing manipulation of said at least one sealing structure.  
     
     
         19 . The sampling port system of  claim 18 , wherein said at least one sealing structure includes a concentric aperture.  
     
     
         20 . The sampling port system of  claim 11 , wherein said at least one sealing structure includes a concentric aperture.
