Abstract

A container may have a base, a sidewall connected to the base, a bell connected to the sidewall, and a finish connected to the bell. The base may have strap ribs to resist deformation of the base. The sidewall may have recessed columns to resist bending, leaning, crumbling, and/or stretching. The strap ribs and recessed columns may vertically line up along a central axis of the container to communicate forces on the container vertically along the container to continuously resist deformation in the base and the sidewall.

First claim

What is claimed is:

1. A container configured to resist deformation in the base and the sidewall comprising:
a flat foot base comprising a gate, a wall, and flat feet, the gate centered on a central axis of the container, the wall extending from the gate toward a resting surface of the container, the flat feet extending from the wall to the resting surface;
a sidewall connected to the base, the sidewall extending substantially along the central axis to define at least part of an interior of the container;
a bell connected to the sidewall and leading upward and radially inward to a finish connected to the bell;
a plurality of pressure resistance bands vertically lined up along the central axis configured to communicate forces on the container vertically along the container between the base and the sidewall to continuously resist deformation in the base and the sidewall;
further comprising a plurality of recessed columns positioned in the sidewall, the recessed columns comprising sidewall ribs extending along a periphery of the sidewall and centered about the central axis, wherein portions of the sidewall between the sidewall ribs are substantially continuous along the periphery of the sidewall, the recessed columns configured to resist at least one of bending, leaning, crumbling, or stretching along the sidewall;
and wherein the sidewall ribs comprise a plurality of varying depth ribs positioned along the periphery of the sidewall, wherein each varying depth rib comprises shallow sections and deep sections, the shallow sections having a rib depth less than a rib depth of the deep sections, wherein the shallow sections of the plurality of varying depth ribs vertically line up along the central axis to form the recessed columns.

2. The container of claim 1 , wherein the container further comprises a plurality of strap ribs positioned in the base between the flat feet, the strap ribs extending radially outward from the wall of the base toward the sidewall, the strap ribs sloping upward relative to the resting surface toward the sidewall from the at least one of the gate or the wall to further resist deformation of the base.

3. The container of claim 2 , wherein the strap ribs extend radially outward from the gate of the base.

4. The container of claim 2 , wherein the base further comprises a plurality of load ribs positioned between the strap ribs, the load ribs having a depth toward the interior of the container shallower than a depth of the strap ribs, the load ribs configured to resist deformation of the base when external forces are applied to the container.

5. The container of claim 1 , wherein the shallow sections have a rib depth of substantially zero from the periphery of the sidewall.

6. The container of claim 1 , wherein the sidewall is substantially round about the periphery of the sidewall, and wherein the plurality of recessed columns comprises three recessed columns positioned in the sidewall equidistantly around the periphery of the round sidewall.

7. The container of claim 6 , wherein the sidewall comprises a grip portion and a label portion, and wherein the three recessed columns are positioned in the grip portion, and the plurality of recessed columns further comprises six recessed columns positioned in the label portion equidistantly around the periphery of the round sidewall, the six recess columns in the label portion configured to inhibit triangulation of the container, wherein three of the six recess columns in the label portion and the three recessed columns in the grip portion vertically line along the central axis.

8. The container of claim 6 , wherein the plurality of strap ribs comprises three strap ribs positioned in the base equidistantly from each other, and wherein the three strap ribs and the three recessed columns vertically line up along the central axis.

9. The container of claim 6 , wherein the plurality of strap ribs comprises six strap ribs positioned in the base equidistantly from each other, three of the six strap ribs and the three recessed columns vertically lined up along the central axis, and wherein the six strap ribs are configured to inhibit triangulation of the container.

10. The container of claim 1 , wherein the sidewall is substantially square about the periphery of the sidewall, and wherein the plurality of recessed columns comprises four recessed columns positioned in the sidewall equidistantly around the periphery of the square sidewall such that each pressure resistance band further comprises another strap rib radially extending 180 degrees opposite the strap rib, the other strap rib vertically lined up along the central axis with another recessed column.

11. The container of claim 10 , wherein the square sidewall comprises corners and flat portions between the corners, and wherein the strap ribs extend toward the flat portions of the square sidewall, the strap ribs configured to resist rounding of the square sidewall at the flat portions.

12. The container of claim 11 , wherein the sidewall ribs comprise a plurality of varying depth ribs positioned along the periphery of the sidewall, wherein each varying depth rib comprises shallow sections and deep sections, the shallow sections having a rib depth less than a rib depth of the deep sections, wherein the shallow sections of the plurality of varying depth ribs vertically line up along the central axis to form the recessed columns, and wherein the deep sections are positioned at the four corners of the square sidewall, the deep sections configured to resist rounding of the square sidewall at the flat portions.

13. A container configured to resist deformation in the base and the sidewall comprising:
a flat foot base comprising a gate, a dome, and flat feet, the gate centered on a central axis of the container, the dome extending from the gate toward a resting surface of the container without contacting the resting surface, the dome surrounding the gate about the central axis, the flat feet extending from the dome to the resting surface;
a sidewall connected to the base, the sidewall extending substantially along the central axis to define at least part of an interior of the container;
a bell connected to the sidewall and leading upward and radially inward to a finish connected to the bell;
a plurality of pressure resistance bands lined up along the central axis with a recessed column, the pressure resistance bands configured to communicate forces on the container vertically along the container between the base and the sidewall to continuously resist deformation in the base and the sidewall; and
the container further comprising a plurality of recessed columns positioned in the sidewall, the recessed columns comprising sidewall ribs, the plurality of sidewall ribs comprising a plurality of varying depth ribs positioned along the periphery of the sidewall.

14. The container of claim 13 , wherein the container further comprises a plurality of strap ribs positioned in the base between the flat feet, the strap ribs extending radially outward from the gate of the base toward the sidewall, the strap ribs sloping upward relative to the resting surface toward the sidewall from the gate to further resist deformation of the base.

15. The container of claim 14 , wherein the strap ribs extend radially outward from the dome of the base.

16. The container of claim 14 , wherein the base further comprises a plurality of load ribs positioned between the strap ribs, the load ribs having a depth toward the interior of the container shallower than a depth of the strap ribs, the load ribs configured to resist deformation of th
