Definitions

  • the present disclosure is directed to plastic bottles, and particularly to a supporting champagne style base that is unitary with the remainder of the bottle, which improves the perpendicularity of the bottle.
  • Plastic bottles that include a base having a continuous uninterrupted standing ring for supporting the bottle on any underlying surface are sometimes referred to having a champagne style base.
  • the perpendicularity or vertical alignment of such bottles can depend on the evenness of material distribution in the area of the standing ring, particularly when the bottles are subjected to even small internal pressures of 15 psi or less. While small variations from a true vertical alignment can be tolerated, any significant variation may cause problems in subsequent labeling and boxing of such bottles. While a large diameter standing ring is generally thought to provide enhanced stability as a result of the larger foot print, the large diameter standing ring is more flexible as a result of less material being present in the standing ring.
  • a plastic bottle has a base centered on a vertical axis.
  • the base has a continuous standing ring to support the bottle on any underlying support surface.
  • a side wall is formed unitarily with the base and extends from the base upward to an upper end of the side wall.
  • a neck is unitarily connected to the upper end of the side wall that includes a finish adapted to receive a cap to close an opening into the bottle interior.
  • the bottle has a height defined by the distance between the opening and the standing ring, and a maximum width across the bottle.
  • the base standing ring can be defined in vertical cross-section by a continuous curve.
  • the base standing ring can have a diameter less than 80% of the maximum side wall width.
  • the continuous curve of the base standing ring can be bounded on a radial inside by an interior region that includes a plurality of concave domed wedge-shaped sections interspaced with buttress sections having substantially planar inclined outer portions.
  • the continuous curve of the base standing ring can be bounded on a radial outside by a conic section portion centered on the vertical axis.
  • the vertical alignment or perpendicularity of the bottle can be enhanced by limiting the apex angle of the conic section portion to less than 160°.
  • the vertical alignment or perpendicularity of the bottle can be further enhanced by maintaining the width of the conic section portion to at least 0.035 inches (0.889 cm).
  • the vertical alignment or perpendicularity of the bottle can also be enhanced by limiting the standing ring diameter to be more than 70% of the maximum bottle side wall width.
  • the vertical alignment or perpendicularity of the bottle can be further enhanced by limiting the average standing ring thickness to between 1.0 and 1.3 times the thickness of the side wall.
  • the vertical alignment or perpendicularity of the bottle can be further enhanced by limiting variation in the standing ring thickness to less than ⁇ 20%.
  • Another feature of the base that can improve the vertical alignment or perpendicularity of the bottle is confining the vertical cross-sectional radius defining the standing ring to between 0.100 inches (0.254 cm) and 0.300 inches (0.762 cm).
  • Another feature of the base that can improve the vertical alignment or perpendicularity of the bottle is limiting the curvature of the concave dome portion to a radius of at least 1.0 times the standing ring diameter.
  • the vertical alignment or perpendicularity of the bottle can be further enhanced by buttress sections that have inclined outer portions that can be inclined at an angle of between 8° and 16° with respect to a plane defined by the base standing ring.
  • the vertical alignment or perpendicularity of the bottle can be further enhanced by providing the angle of tangency at the point of intersection of the concave dome portion and the standing ring vertical cross-section to be at least 45°.
  • FIG. 1 is a sectional outline of an exterior surface of a bottle.
  • FIG. 2 is a bottom plan view of the base of the bottle in FIG. 1 .
  • FIG. 3 is a sectional outline view of the base taken along line 3 - 3 of FIG. 2 .
  • FIG. 4 is an enlarged view of a portion of the left side of FIG. 3 .
  • FIG. 5 is an enlarged view of a portion of the right side of FIG. 3 .
  • a bottle 10 is shown in FIG. 1 and the other Figs that has a generally cylindrical body 12 surrounding a longitudinal axis Y and a closed base 14 that is unitary with the remainder of the bottle.
  • the 14 base has a continuous standing ring 16 to support the bottle 10 on any underlying support surface.
  • the standing ring 16 has a standing ring diameter D.
  • a side wall 18 is formed unitarily with the base 14 and extends from the base upward to an upper end 20 of the side wall 18 .
  • a neck 22 is unitarily connected to the upper end 20 of the side wall 18 by a shoulder portion 21 .
  • the neck 22 includes a finish 24 adapted to receive a cap (not shown) to close an opening 26 into the bottle interior 28 .
  • the bottle 10 has a height H defined by the distance between the opening 26 and the standing ring 16 , and a maximum width W across the bottle 10 .
  • the base standing ring 16 can be defined in vertical cross-section by a continuous curve of radius R S , shown in FIGS. 4 and 5 , which can be between 0.100 inches (0.254 cm) and 0.300 inches (0.762 cm).
  • the radius R S is independent of the standing ring diameter D, where the standing ring diameter D is measured at the lowest point on the standing ring 16 .
  • the curve defining the standing ring 16 is continuous, does not include any flattened portion in the plane X defined by the standing ring, shown in FIG. 3 .
  • the base standing ring 16 can have a diameter D less than 80% of the maximum side wall width W.
  • the base standing ring 16 can have a diameter D greater than 70% of the maximum side wall width W.
  • the continuous curve of the base standing ring 16 defined by R S can be bounded on a radial inside, starting about at point or ring 30 , by an interior region 32 .
  • the interior region 32 can include a plurality of concave domed wedge-shaped sections 34 as seen in FIG. 2 .
  • the concave domed wedge-shaped sections 34 can be formed by a constant inside radius R C of at least 1.0 times the standing ring diameter D as shown in FIGS. 3 and 5 .
  • the angle of tangency ⁇ at the point of intersection 30 of the concave dome portions 34 and the curve defining the standing ring 16 measured from the plane X as shown in FIG. 5 can be between 45°and 55°.
  • the wedge-shaped sections 34 can be interspaced with buttress sections 36 , which can also be wedge-shaped.
  • the buttress sections 36 can have substantially planar inclined outer portions 38 .
  • the planar outer portions 38 can be inclined at an angle ⁇ of between 8° and 16° with respect to a plane X defined by the base standing ring 16 as seen in FIG. 4 .
  • the buttress sections 36 can include inner portions 40 defined by a concave surface 42 that becomes circumferentially continuous as it approaches a central downwardly protruding portion 44 surrounding the axis Y of the bottle.
  • the lowest surface of the downwardly protruding portion 44 can be spaced above the plane X by a distance H C of 14% to 20% of the standing ring diameter D.
  • the continuous curve of the base standing ring 16 defined by radius R S can be bounded on a radial outside by a conic section portion 46 starting at point or ring 48 and extending linearly upwardly and outwardly to point or ring 50 as shown in FIGS. 4 and 5 .
  • the distance between point or ring 48 and point or ring 50 defines the width of the conic section portion 46 , which is preferably at least 0.035 inches (0.089 cm).
  • the conic section portion 46 is seen to be generated by the rotation around the vertical axis Y of a line generating a conic section having an included apex angle ⁇ of less than 160° as shown in FIG. 3 .
  • a base outer portion 52 extending outward from point 50 to the side wall 18 can be formed as a torus segment defined by a constant radius R T of between about 12% and 20% of the standing ring diameter D.
  • the material forming the standing ring 16 preferably has an average thickness of between 1.0 and 1.3 times the thickness of the material forming the side wall 18 .
  • the thickness of the material forming the standing ring 16 desirably has a variation that is as small as possible and less than ⁇ 20%.
