Sample Cup Inner Member with Integral Venting Cap

Abstract

This invention relates to the design and construction of a novel sample cup inner member including an integral venting cap for use in XRF Spectroscopy.

What is claimed: 
     
         1 . A sample cup inner member for retaining a sample to be analyzed spectrochemically, said inner member comprising:
 a top closed end, a bottom open end, a cap, and including a protrusion situated on an inner surface of said cap to facilitate venting of an assembled sample cup when the top surface of said cap is depressed.   
     
     
         2 . The sample cup inner member according to  claim 1 , wherein said top closed end is disposed from a top wall edge of said inner member. 
     
     
         3 . The sample cup inner member according to  claim 1 , wherein said cap is integrally hinged about the top wall edge of said inner member. 
     
     
         4 . The sample cup inner member according to  claim 2 , wherein said cap is integrally hinged about the top wall edge of said inner member. 
     
     
         5 . The sample cup inner member according to  claim 1 , wherein said cap sits flush with the top wall edge of said inner member when assembled. 
     
     
         6 . The sample cup inner member according to  claim 2 , wherein said cap sits flush with the top wall edge of said inner member when assembled. 
     
     
         7 . The sample cup inner member according to  claim 3 , wherein said cap sits flush with the top wall edge of said inner member when assembled.
