ABSTRACT:
This disclosure relates to a plastic bottle having a bottom structure of the champagne bottle type. The bottom is reinforced by radiating ribs which are circumferentially spaced and the ribs, utilizing a minimum of material, stiffen the bottom so as to prevent the domed inner section of the bottom from reverting and also greatly resist creep of the bottom under the influence of time and internal pressure. The ribs may be only across the juncture section between inner and outer sections of the bottom, or may extend entirely from the outer section across the juncture section and substantially to the domed center of the domed section. The ribs may also be upstanding and serve to function as guides for a liquid product being placed into the bottle so as to reduce turbulences and aid in expediting the filling operation.
