          Appeal No. 1998-2029                                      Page 15           
          Application No. 08/258,643                                                  


          prior art of Morris and Staller clearly would have suggested                
          to a person having ordinary skill in the art that adhesive and              
          interlocking rib and groove closure elements were known                     
          sealing alternatives at the time the invention was made.                    
          Accordingly, the substitution of interlocking rib and groove                
          closure elements for an adhesive seal would have been obvious               
          at the time the invention was made to a person having ordinary              
          skill in the art.                                                           


               For the reasons set forth above, the decision of the                   
          examiner to reject claim 3 under 35 U.S.C. § 103 is affirmed.               


                                     CONCLUSION                                       
               To summarize, the decision of the examiner to reject                   
          claims 1-6, 10 and 11 under 35 U.S.C. § 103 is affirmed and                 
          the decision of the examiner to reject claims 7-9 under 35                  
          U.S.C. § 103 is reversed.
