Abstract

Abstract A plastics bottle for carbonated drinks has a side wall (4) and a base (5) formed with a central area (8) surrounded by circumferentially spaced projecting feet (6) separated by substantially parallel-sided straps (7). The central area (8) and the straps (7) define a continuous smooth domed surface with no re-entrant portions. The ratio of the combined width of the straps (7) to the outside circumference of the base (5) is in the range from 1:5.5 to 1:6.5 and preferably 1:6. Preferably the base (5) has only seven projecting feet (6). This configuration is particularly useful with bottles of small size and enables a saving in plastics material of up to 40% by weight.

Claims Analysis

Total Claims: 19
Claim 1
Independent Claim 88 words
In a plastics bottle for carbonated drinks having a side wall, a base, a central area in said base, circumferentially spaced projecting feet in said base surrounding said central area, and substantially parallel-sided straps lying between and separating said spaced projecting feet, the improvement wherein said central area and said straps together define a continuous smooth domed surface with no re-entrant portions, and wherein a ratio of the combined width of said straps to the outside circumference of said base is in a range from 1:5.5 to 1:6.5.
Claim 2
Dependent Claim 88 words
In a plastics bottle for carbonated drinks having a side wall, a base, a central area in said base, circumferentially spaced projecting feet in said base surrounding said central area, and substantially parallel-sided straps lying between and separating said spaced projecting feet, the improvement wherein said central area and said straps together define a continuous smooth domed surface with no re-entrant portions, and wherein a ratio of the combined width of said straps to the outside circumference of said base is in a range from 1:5.5 to 1:6.5.
Claim 3
Dependent Claim 27 words
A plastics bottle according to claim 1, wherein said ratio of said combined width of said straps to said outside circumference of said base is substantially 1:6.
Claim 4
Dependent Claim 15 words
A plastics bottle according to claim 2, wherein said base has only seven projecting feet.
Claim 5
Dependent Claim 16 words
A plastics bottle according to claim 3, which is made by an injection-stretch blow moulding technique.
Claim 6
Dependent Claim 35 words
A plastics bottle according to claim 4, wherein a radius of curvature of said domed surface defined by the straps falls within a range from 75% to 85% of the outside radius of said base.
Claim 7
Dependent Claim 32 words
A plastics bottle according to claim 5, wherein said feet extend below said central area to a depth in a range from 6 to 8% of the outside diameter of said base.
Claim 8
Dependent Claim 87 words
A plastics bottle according to claim 6, wherein each said foot comprises an inwardly tapered side portion, a generally triangular bottom portion, said generally triangular bottom portion tapering towards its radially innermost end, and a curved portion, said curved portion connecting said side and bottom portions and having a radius of curvature which is substantially one third of the radius of curvature of said straps, and wherein said side portion is curved with a radius of curvature which is substantially three times said radius of said straps.
Claim 9
Dependent Claim 62 words
A plastics bottle according claim 7, wherein a stand diameter of said feet falls within a range from 66 to 76% of the outside diameter of said bottle, said stand diameter being defined as the outside diameter of a circle touching outermost regions of contact of said feet with a plane surface when said bottle is standing upright on that plane surface.
