          Appeal No. 96-0681                                                          
          Application 08/041,715                                                      

               them from plastic, and would increase the efficiency of                
               the desiccant by allowing more gas to pass through the                 
               container per unit time.                                               
          Also, on page 7 of the answer:                                              
               Clearly the Russell et al reference is being utilized                  
               to teach the well[-]known advantages of constructing                   
               the inventive apparatus from molded plastic                            
               (advantage : economics), constructing the inventive                    
               apparatus with apertures in both ends (advantage :                     
               greatly gas passage through the container per unit                     
               time), and constructing the inventive apparatus with                   
               the apertures terminating in a substantially planar                    
               inner surface of the end caps (advantage : lessened                    
               abrading of the desiccant).                                            
               After fully considering the record in light of the arguments           
          made in the appellants’ brief and the examiner’s answer, we                 
          conclude that the rejection was not well taken.                             
               We agree with the examiner that it would have been obvious,            
          in view of Russell, to make the body 11 and cap 12 of the                   
          Kleinhans container 10 out of molded plastic, this being simply             
          the obvious use of a well-known material.  As for the cap 12 of             
          Kleinhans, it appears to be made of metal, with the apertures               
          (“ports”) 22 being punched through it.  If cap 12 of Kleinhans              
          were made of molded plastic rather than metal, the apertures 22             
          would be included as part of the molding process and, not being             
          punched like the Kleinhans apertures, would not have inner ends             
          protruding beyond the inner surface of the cap, but rather would
