Plastic water bottle

Abstract

A molded plastic container for carbonated and non-carbonated beverages. The plastic container includes an upper mouth-forming portion, a cylindrical sidewall portion and a lower base-forming portion. The upper mouth-forming portion includes a non-circular anti-rotation flange adapted to at least partially inhibit full rotation of the container as a cap is inserted on the container. The anti-rotation flange typically has an outer perimeter shape of a heptagon. The lower base-forming portion can include a variety of different configurations.

         10 . The plastic container as defined in  claim 1 , wherein said lower base-forming portion includes a plurality of hollow foot-forming portions extending outwardly from a central portion of the lower base-forming portion to form a plurality of feet.  
     
     
         11 . The plastic container as defined in  claim 10 , wherein each foot-forming portion increases circumferentially in size as it extends radially.  
     
     
         12 . The plastic container as defined in  claim 1 , wherein said lower base-forming portion has a substantially flat base.  
     
     
         13 . The plastic container as defined in  claim 1 , wherein said lower base-forming portion has a champagne-type base.  
     
     
         14 . The plastic container as defined in  claim 1 , wherein said plastic is polyethylene terephthalate.  
     
     
         15 . A container comprising an upper mouth-forming portion, a sidewall portion and a lower base-forming portion, said upper mouth-forming portion including a non-circular anti-rotation flange adapted to at least partially inhibit full rotation of said container as a cap is inserted on said container.  
     
     
         16 . The container as defined in  claim 15 , wherein said container is a molded plastic container.  
     
     
         17 . The container as defined in  claim 16 , wherein said plastic is polyethylene terephthalate.  
     
     
         18 . The container as defined in  claim 15 , wherein said container is for beverages.  
     
     
         19 . The container as defined in  claim 15 , wherein said anti-rotation flange includes at least one substantially straight surface.  
     
     
         20 . The container as defined in  claim 19 , wherein said anti-rotation flange includes a plurality of straight surfaces.  
     
     
         21 . The container as defined in  claim 20 , wherein said anti-rotation flange has an outer perimeter shape of a heptagon.  
     
     
         22 . The container as defined in  claim 15 , wherein said anti-rotation flange includes at least one notch.  
     
     
         23 . The container as defined in  claim 22 , wherein said notch has a V-shape.  
     
     
         24 . The container as defined in  claim 22 , wherein said notch has at least one arcuate surface.  
     
     
         25 . The container as defined in  claim 15 , wherein said lower base-forming portion includes a plurality of hollow foot-forming portions extending outwardly from a central portion of the lower base-forming portion to form a plurality of feet.
