Ex parte LANDA et al. - Page 11

          Appeal No. 1997-2118                                                        
          Application No. 08/119,163                                                  

               I note that Landa teaches in column 2, lines 43 through                
          44, that the preferred embodiment of the invention is to                    
          include a replaceable enclosure which is the container 66                   
          shown in Figure 2.  Landa further teaches that container 66 is              
          replaced by a fully charged container in column 6, lines 67                 
          and 68.  Thus, the Landa container 66 is a disposable item.                 
          Uhlig teaches in column 1, lines 36 through 40 that one of the              
          problems of prior art throw away dispensers is that it creates              
          an additional economic problem of garbage or trash disposal.                
          Uhlig further teaches that the cost of the dispenser structure              
          is high when the dispenser includes sophisticated type                      
          designs.  I note that Landa's dispenser structure is a                      
          sophisticated design wherein the throw away dispenser is a                  
          metal container including the mechanical pressure means.                    
          Uhlig teaches in column 1, lines 58 through 63, that their                  
          invention provides an inexpensive flexible bag to hold the                  
          dispensing product.  After the product is dispensed, the inner              
          bag may be easily disposed of and replaced.  Uhlig teaches                  
          that their invention provides ecological advantages since only              
          the inner bag has to be thrown away.  From these teachings, I               
          would have found that one of ordinary skill in the art would
