               Appeal No. 2003-0503                                                                                5                 
               Application No. 09/687,894                                                                                            


               calling for the ballast member to be sized to create an interference fit (claims 1 and 10), or                        
               direct attachment (claim 15), with some part of the material of the body portion that                                 
               defines the cavity therein.  In our view, the examiner’s position to the contrary is simply not                       
               reasonable.                                                                                                           
                       In light of the above, we will not sustain the examiner’s rejection of claims 1 and 3-                        
               15 under 35 U.S.C. § 112, second paragraph.                                                                           
               Rejection (2)                                                                                                         
                       Claim 1 calls for a ballast member that is separate and distinct from the body                                
               portion, receivable within the cavity of body portion, and sized to create an interference fit                        
               with the cavity of the body portion.  The examiner contends that the closure member 52 in                             
               the Figures 14-16 embodiment of Metz meets these requirements.  Appellant does not                                    
               appear to dispute the examiner’s position that closure member 52 of Metz is separate and                              
               distinct from the balloon holder 50, and receivable within the cavity formed in the                                   
               underside of the balloon holder 50.  Appellant also does not appear to dispute the                                    
               examiner’s position that closure member 52 is sized to create an interference fit with a wall                         
               portion of the cavity of the balloon holder by virtue of the cooperation of pins 57 of the                            
               closure member with bosses 56 of the balloon holder.  Instead, appellant argues that the                              
               examiner erred in the first instance in considering closure member 52 of Metz to be a                                 
               ballast member.  More particularly, appellant argues that the examiner has                                            
               mischaracterized what is taught by Metz, that the examiner’s analysis of Metz is hindsight
