Abstract
A container can have a body with an integrally formed base attached to the body. The base includes a concave annular wall extending from the container sidewall to a standing surface, and an inner wall extending from the standing surface to a substantially flat inner annular wall. The inner annular wall is recessed in the base and is substantially perpendicular to the container sidewall. The inner annular wall includes a centrally located dimple. The dimple includes a plurality of spaced apart and radially extending indented ribs. One or more of the ribs extend radially into a brace that tapers to meet the inner annular wall.
Claims17
A plastic container comprising:
- an upper portion including a finish defining an opening into the container;
- a lower portion including a base defining a standing surface;
- a sidewall extending between the upper portion and the lower portion, the sidewall defining a longitudinal axis;
- at least one substantially transversely-oriented pressure panel located in the lower portion, the pressure panel being movable between an outwardly-inclined position and an inwardly-inclined position to compensate for a change of pressure inside the container;
- a dimple (248) centrally located within the pressure panel;
- and
- a plurality of radially spaced tapered ribs (250), each of said plurality of tapered ribs tapering between a narrowest part and a widest part of each said rib, the narrowest part being radially outward of said widest part, the widest part being arranged adjacent the dimple,
- wherein the standing surface defines a standing plane, and the entire pressure panel is located between the standing plane and the upper portion of the container when the pressure panel is in the outwardly-inclined position, and
- wherein each of the tapered ribs is generally trapezoidal in plan view with the widest and narrowest parts defining bases of the trapezoid in the plan view.

- a plurality of radially spaced tapered ribs, each of said plurality of tapered ribs tapering between a narrowest part and a widest part of each said rib, the narrowest part being radially outward of said widest part,
- wherein the standing surface defines a standing plane, and the entire pressure panel is located between the standing plane and the upper portion of the container when the pressure panel is in the outwardly-inclined position, and

A plastic container comprising:
- an upper portion including a finish defining an opening into the container;
- a lower portion including a base with a standing surface defining a standing plane, the lower portion having a diameter D;
- a sidewall extending between the upper portion and the lower portion, the sidewall defining a longitudinal axis and having a diameter less than diameter D, the sidewall adapted to neatly support a wrap-around label without unwanted voids beneath the label;
- at least one substantially transversely-oriented pressure panel located in the lower portion, the pressure panel being movable between an outward position and an inward position above said outward position to compensate for a change of pressure inside the container;
- an anti-inverting dome located centrally of the pressure panel, the anti-inverting dome adapted to travel with the pressure panel and to maintain substantially a constant shape regardless of the internal pressures experienced within the container, preventing complete inversion and failure of the pressure panel, the anti-inverting dome being configured to help prevent the pressure panel from moving outside a desired range of movement between two positions B and C;
- and
- a plurality of radially spaced tapered ribs, each of said plurality of tapered ribs tapering between a narrowest part and a widest part of each said rib, the narrowest part being radially outward of said widest part,
- wherein each of the to tapered ribs is generally trapezoidal in plan view with the widest and narrowest parts defining bases of the trapezoid in the plan view.
