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: 11
Claim 1
Independent Claim
90 words
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) lying on a domed surface (S), characterised in that the central area (8) and the straps (7) define a continuous smooth domed surface with no re-entrant portions, and in that 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.
Claim 2
Dependent Claim
90 words
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) lying on a domed surface (S), characterised in that the central area (8) and the straps (7) define a continuous smooth domed surface with no re-entrant portions, and in that 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.
Claim 3
Dependent Claim
30 words
A plastics bottle according to claim 1, in which the ratio of the combined width of the straps (7) to the outside circumference of the base (5) is substantially 1:6.
Claim 4
Dependent Claim
18 words
A plastics bottle according to claim 1 or 2, in which the base has only seven projecting feet.
Claim 5
Dependent Claim
18 words
A plastics bottle according to any one of the preceding claims, made by an injection-stretch blow moulding technique.
Claim 6
Dependent Claim
46 words
A plastics bottle according to any one of the preceding claims, in which the radius of curvature (r s ) of the domed surface (S) defined by the straps (7) falls within the range from 75% to 85% of the outside radius of the base (5).
Claim 7
Dependent Claim
40 words
A plastics bottle according to any one of the preceding claims, in which the feet (6) extend below the central area (8) to a depth in a range from 6 to 8% of the outside diameter of the base (5).
Claim 8
Dependent Claim
93 words
A plastics bottle according to any one of the preceding claims, in which each foot (6) comprises an inwardly tapered side portion and a generally triangular bottom portion which tapers towards its radially innermost end, the side and bottom portions being connected by a curved portion having a radius of curvature (r f ) which is substantially one third of the strap radius (r s ), and in which the side portion is curved with a radius of curvature (r p ) which is substantially three times the strap radius (r s ).
Claim 9
Dependent Claim
68 words
A plastics bottle according to any one of the preceding claims, in which the stand diameter of the feet (6) which is defined as the outside diameter of a circle touching the outermost regions of contact of the feet (6) with a plane surface when the bottle is standing upright on that surface, falls within a range from 66 to 76% of the outside diameter of the bottle.
Claim 10
Dependent Claim
31 words
A plastics bottle according to any one of the preceding claims, in which the wall thickness of the side wall (4), feet (6) and straps (7) is not greater than 0.3mm.
Claim 11
Dependent Claim
26 words
A plastics bottle according to any one of the preceding claims, in which the bottle has a nominal capacity of between 185 ml and 500 ml.
