Estimating the term…
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.
A bottom structure of a thermoplastic bottle, said bottom structure comprising an outer bottom portion having a radially inner lower edge, an inner generally radially and axially concaved bottom portion disposed within said outer bottom portion in recessed relation and having a radially outer lower edge, and a continuous annular generally arcuate cross-sectional intermediate bottom portion joining the lower edges of said outer bottom portion and said inner bottom portion;
A bottom structure of a thermoplastic bottle, said bottom structure comprising an outer bottom portion having a radially inner lower edge, an inner generally radially an axially concaved bottom portion disposed within said outer bottom portion in recessed relation and having a radially outer lower edge, and a continuous annular generally arcuate cross-sectional intermediate bottom portion joining the lower edges of said outer bottom portion and said inner bottom portion;
