Container with pressure accommodation panel

1. A container comprising:

a first vacuum panel,

a second vacuum panel,

a third vacuum panel,

a first diagonal column between the first vacuum panel and the second vacuum panel, and

a second diagonal column between the second vacuum panel and the third vacuum panel,

wherein a height of the first vacuum panel is greater than a height of the second vacuum panel and a height of the third vacuum panel,

wherein the second vacuum panel and the third vacuum panel are oriented in opposite directions,

wherein, in response to a change in an internal container pressure, the container flexes at the first vacuum panel such that a surface of the first vacuum panel increases in concavity in response to an increasing pressure change,

wherein the first vacuum panel is disposed horizontally next to the second vacuum panel, and

wherein the second vacuum panel is disposed horizontally next to the third vacuum panel.

2. The container of claim 1 , wherein the increase in concavity comprises a first portion of the surface moving towards an interior of the container and a second portion of the surface moving towards the interior of the container by a different distance than the first portion.

3. The container of claim 2 , wherein the surface is a middle surface.

4. The container of claim 3 , wherein the first vacuum panel comprises an upper surface and a lower surface, and concavities of the upper surface and the lower surface increase in response to the increasing pressure change.

5. The container of claim 4 , wherein the increase in the concavity of the upper surface is different than the increase in the concavity of the lower surface.

6. The container of claim 1 , wherein a height of the first vacuum panel is at least one-third a total height of the container.

7. The container of claim 1 , wherein the second vacuum panel and the third vacuum panel each comprises a base, and wherein a distance measured from the base of the second vacuum panel to the base of the third vacuum panel is at least one-third a total height of the container.

8. The container of claim 1 , wherein a height of the second vacuum panel is at least one-fourth a total height of the container.

9. The container of claim 1 , wherein the first vacuum panel has two sides that are angled with respect to a longitudinal axis of the container.

10. The container of claim 1 , wherein the second vacuum panel and the third vacuum panel each comprise a base and two sides, wherein the two sides of each vacuum panel form an acute angle.

11. The container of claim 10 , wherein the second vacuum panel and the third vacuum panel are triangular.

12. The container of claim 10 , wherein, in response to the change in the internal container pressure, the container flexes at the second vacuum panel and the third vacuum panel such that the base of each panel increases in concavity in response to the increasing pressure change.

13. The container of claim 12 , wherein the flexing of the container decreases the initial volume by 5%.

14. The container of claim 1 , wherein the container has an initial volume, and wherein the flexing of the container decreases the initial volume by 3%.

15. The container of claim 1 , wherein the container has an oval horizontal cross section at a position intersecting the first vacuum panel, the second vacuum panel, and the third vacuum panel.

16. The container of claim 1 , wherein the first diagonal column and second diagonal column intersect.

17. The container of claim 1 , further comprising:

a shoulder portion;

a base portion; and

a body portion between the shoulder portion and the based portion,

wherein the flexing of the container causes the container to deform, and wherein at least 90% of the deformation of the container occurs in the body portion.

18. A container for storing a liquid filled in a hot state and then sealed, the container comprising:

a diagonal pressure accommodation panel;

a first triangular pressure accommodation panel; and

a second triangular pressure accommodation panel,

wherein the first triangular pressure accommodation panel and the second triangular pressure accommodation panel are oriented in opposite directions,

wherein the diagonal pressure accommodation panel is disposed between the first triangular pressure accommodation panel and the second triangular pressure accommodation panel such that sides of the diagonal pressure accommodation panel align with sides of the first triangular pressure accommodation panel and the second triangular pressure accommodation panel,

wherein, in response to a reduction in volume when the container is sealed, the diagonal pressure accommodation panel is configured to twist from an original shape to accommodate the reduction in volume, and

wherein, when the seal is released, the diagonal pressure accommodation panel is configured to return to its original shape.

19. The container of claim 18 , wherein the twist is initiated by cooling of the liquid.
