Container pressure base

1. A polymeric container formed from a preform and configured for storing a commodity under pressure, the polymeric container comprising:

a base including a standing ring configured to support the container upright when the standing ring is seated on a planar standing surface;

a curved diaphragm of the base extending from the standing ring to a center of the base; and

a plurality of dimples defined by the base and evenly spaced apart along the standing ring:

wherein:

the plurality of dimples includes first dimples and second dimples;

the first dimples have a smaller surface area than the second dimples;

the first dimples are shorter than the second dimples;

each one of the first dimples is between two of the second dimples and each one of the second dimples is between two of the first dimples;

the first dimples extend from the standing surface to along the curved diaphragm of the container, the first dimples intersect the heel along a first longitudinal axis at an angle of less than 90°, the first longitudinal axis extends along a center of a length of each of the first dimples, the first dimples extend linearly and are flat in cross-section along the first longitudinal axis, and the first dimples are symmetrical on opposite sides of the first longitudinal axis;

the second dimples extend from the standing surface to along the heel of the base, the second dimples intersect the curved diaphragm along a second longitudinal axis at an angle of less than 90°, the second longitudinal axis extends along a center of a length of each of the second dimples, the second dimples extend linearly and are flat in cross-section along the second longitudinal axis, and the second dimples are symmetrical on opposite sides of second longitudinal axis;

the first dimples extend further along the curved diaphragm than the second dimples, and the second dimples extend further along the heel than the first dimples;

each one of the first dimples is opposite to another one of the first dimples on opposite sides of the center of the base; and

each one of the second dimples is opposite to another one of the second dimples on opposite sides of the center of the base.

2. The container of claim 1 , wherein the base is a champagne-style base.

3. The container of claim 1 , wherein the standing ring extends along a line of symmetry of each one of the plurality of dimples.

4. The container of claim 1 , wherein the base has a surface area ratio of dimples to non-dimples of 3:1.

5. The container of claim 1 , wherein the base has a surface area ratio of dimples to non-dimples of 6:1.

6. The container of claim 1 , wherein the plurality of dimples are round, oval, obround, or elliptical in shape.

7. The container of claim 1 , wherein the container is configured to store the commodity having a CO 2 level of at least 3.2 gv.

8. The container of claim 1 , wherein the container is configured to store the commodity having a CO 2 level of at least 4.2 gv.

9. The container of claim 1 , wherein the container includes a body between the base and a finish of the container, the body includes a sidewall having a sidewall thickness that is thinner than a base thickness of the base at the standing ring.

10. The container of claim 1 , wherein the container includes 8-14 of the plurality of dimples.

11. The container of claim 1 , wherein the plurality of dimples form an “X” pattern in relation to the curved diaphragm.

12. The container of claim 1 , further comprising a body defining an internal volume of the container, the body includes an upper body portion, a lower body portion, and a waist between the upper body portion and the lower body portion;

wherein the body is narrower at the waist as compared to the upper body portion and the lower body portion.

13. The container of claim 1

wherein the first longitudinal axes and the second longitudinal axes intersect in cross-section at a centerline of the standing ring.

14. The container of claim 1 , wherein the curved diaphragm includes a center portion at an axial center of the curved diaphragm, the center portion protrudes outwardly from the curved diaphragm away from an interior volume of the container.
