Pressurized gas sampling container

Abstract

A gas sampling container capable of obtaining, isolating and transporting samples of gas or other fluid under pressure form. The container further exhibits a plurality of simple, reliable, inexpensive, self sealing, valves which allow the introduction, flow through and exit of the gas sample. The container is suitable for taking discrete or serial samples from a gas or fluid flow source and is especially suited for use in automated sampling apparatus. These containers are acceptable for shipment of compressed flammable gases under the regulatory structures of many countries.

1 . A container for gas or fluid comprising:
 a first end,   a second end,   a plurality of valves fluidly connected to said container whereby a gas or fluid may enter, flow through and exit said container.   
   
   
       2 . The container for gas or fluid of  claim 1  constructed of metal, aluminum, steel, plastic, polymer or carbon fiber capable of containing fluid or gas under pressure. 
   
   
       3 . The container of  claim 2  further comprising:
 a first valve fluidly connected to said first container end,   a second valve fluidly connected to said second container end whereby a gas or fluid may enter through said first valve, flow through said container, and exit through said second valve.   
   
   
       4 . The container of  claim 3  wherein said first valve and said second valve are self sealing whereby said gas or fluid may be retained within said container under pressure. 
   
   
       5 . The container of  claim 4  wherein said first valve and said second valve are plunger activated. 
   
   
       6 . The container of  claim 1  wherein said first end is a closed end and said second end is open end. 
   
   
       7 . The container of  claim 5  wherein said closed end is perforated by a circular aperture. 
   
   
       8 . The container of  claim 7  wherein said first valve is disposed within said circular aperture. 
   
   
       9 . The container of  claim 8  wherein said open end exhibits a rolled lip. 
   
   
       10 . The container of  claim 9  further comprising a cap, said cap disposed through said open end. 
   
   
       11 . The container of  claim 10  wherein said cap exhibits a partially rolled flange whereby when said cap is disposed through said open end, said partially rolled flange communicates with said rolled lip forming a seal. 
   
   
       12 . The container of  claim 11  wherein said rolled flange is formed around and under said rolled lip whereby said cap is retained over said rolled lip. 
   
   
       13 . The container of  claim 11  further comprising a seal, said seal disposed between said partially rolled flange and said rolled lip whereby a fluid tight seal is created 
   
   
       14 . The container of  claim 12  wherein said cap further comprises a cap aperture. 
   
   
       15 . The container of  claim 13  further comprising a second valve disposed through said cap aperture. 
   
   
       16 . The container of  claim 14  wherein said cap exhibits cap walls that extend within said open end and below said rolled lip. 
   
   
       17 . The container of  claim 15  wherein said cap wall further comprises an expanded lip whereby said expanded lip provides pressure on said rolled lip wherein said rolled lip is compressed between said rolled flange and said expanded lip. 
   
   
       18 . The container of  claim 15  further comprising a fluid extraction or injection means wherein said first valve and said second valve may be fluidly connected to said fluid extraction or injection device.
