Abstract

Container includes a top portion, a body portion and a bottom portion. The body portion includes a front wall, a rear wall and first and second side walls, the first side wall disposed opposite the second side wall, opposing grip areas formed in the first and second side walls, a first circumferential rib disposed above the opposing grip areas and extending horizontally about an entire outer circumferential perimeter of the body portion, a second circumferential rib disposed below the opposing grip areas and extending horizontally about the entire outer circumferential perimeter of the body portion, at least one horizontal body rib disposed between and spaced circumferentially from the opposing grip areas, a first vertical strut formed in the first side wall and a second vertical strut formed in the second side wall, each strut disposed between the first and second circumferential ribs and spaced a distance from each grip area.

First claim

The invention claimed is:

1. A container comprising:
a top portion comprising a finish portion;
a body portion disposed below the top portion; and
a bottom portion disposed below the body portion opposite the top portion;
the body portion comprising:
a front wall,
a rear wall opposite the front wall,
first and second side walls extending between the front wall and the rear wall to define a generally rectangular shape in plan view, the first side wall disposed opposite the second side wall,
opposing grip areas formed in the first and second side walls, the opposing grip areas including a first grip area formed in the first side wall and a second grip area formed in the second side wall,
a first circumferential rib disposed above the opposing grip areas and extending horizontally about an entire outer circumferential perimeter of the body portion,
a second circumferential rib disposed below the opposing grip areas and extending horizontally about the entire outer circumferential perimeter of the body portion,
at least one horizontal body rib disposed between the first and second circumferential ribs and spaced from the opposing grip areas, and
a first vertical strut formed in the first side wall and spaced from the first grip area and a second vertical strut formed in the second side wall and spaced from the second grip area, each of the first and second vertical struts disposed between and spaced from the first and second circumferential ribs and having a length coextensive with a height of the first and the second grip areas respectively, the first and second vertical struts configured to resist radially-inward distortion of the first and second side walls from gripping the opposing grip areas.

2. The container of claim 1 , wherein the body portion has a substantially square shape in plan view.

3. The container of claim 1 , wherein the body portion comprises rounded corners at opposing ends of the first and second side walls in plan view.

4. The container of claim 1 , wherein each opposing grip area has a textured surface formed therein.

5. The container of claim 1 , wherein each opposing grip area has an elongated recess formed therein.

6. The container of claim 1 , wherein the opposing grip areas are disposed on the first and second side walls closer to the rear wall than the front wall.

7. The container of claim 1 , wherein each opposing grip area projects inwardly a distance between 10% and 20% of a greatest width of the rear wall.

8. The container of claim 1 , further comprising a transition portion along the outer circumferential perimeter to an upper portion of each opposing grip area defining an angle between 45 degrees and 70 degrees from the outer circumferential perimeter to each opposing grip area.

9. The container of claim 1 , wherein the rear wall has a contour defining at least a portion of the opposing grip areas.

10. The container of claim 1 , wherein the first circumferential rib and the second circumferential rib have substantially equal depths.

11. The container of claim 1 , wherein the first and second circumferential ribs each has a depth between 3% and 5% of a width of the first and second side walls.

12. The container of claim 1 , wherein the first circumferential rib and the at least one horizontal body rib have a substantially equal depth.

13. The container of claim 1 , wherein the at least one horizontal body rib has a depth between 3% and 5% of a width of the first and second side walls.

14. The container of claim 1 , wherein the at least one horizontal body rib is formed in the front wall.

15. The container of claim 14 , wherein the at least one horizontal body rib extends from the front wall about rounded corners disposed between the front wall and the first and second side walls, respectively.

16. The container of claim 14 , wherein the at least one horizontal body rib comprises a plurality of horizontal body ribs.

17. The container of claim 16 , wherein the plurality of horizontal body ribs comprises four horizontal body ribs.

18. The container of claim 16 , wherein each of the plurality of horizontal body ribs are spaced vertically an equal distance from each adjacent horizontal body rib.

19. The container of claim 16 , wherein the plurality of horizontal body ribs are spaced vertically an equal distance from the first and second circumferential ribs.

20. The container of claim 14 , further comprising at least one opposing horizontal body rib formed in the rear wall.

21. The container of claim 20 , wherein the at least one horizontal body rib comprises a plurality of horizontal body ribs and the at least one opposing horizontal body rib comprises a plurality of opposing horizontal body ribs.

22. The container of claim 21 , wherein the plurality of horizontal body ribs comprises four horizontal body ribs and the plurality of horizontal opposing horizontal body ribs comprises four opposing horizontal body ribs.

23. The container of claim 1 , wherein only one vertical strut is formed in the front sidewall and only one vertical strut is formed in the second side wall, each vertical strut is disposed between a corresponding one of the first and second grip areas and the at least one horizontal body rib.

24. The container of claim 1 , wherein each vertical strut has a depth between 2% and 5% of a width of the first and second side walls.

25. The container of claim 1 , wherein each vertical strut has a varied width along its length.

26. The container of claim 1 , wherein the container comprises polyethylene terephthalate.

27. The container of claim 1 , wherein the container has a volume of about 59 ounces formed from a preform having a mass of about 58 grams.

28. A container comprising:
a top portion comprising a finish portion;
a body portion disposed below the top portion; and
a bottom portion disposed below the body portion opposite the top portion;
the body portion comprising:
a front wall,
a rear wall opposite the front wall,
first and second side walls extending between the front wall and the rear wall to define a generally rectangular shape in plan view, the first side wall disposed opposite the second side wall,
opposing grip areas formed in the first and second side walls, the opposing grip areas including a first grip area formed in the first side wall and a second grip area formed in the second side wall,
one or more strengthening features selected from the group consisting of:
(i) at least one circumferential rib spaced from the opposing grip areas and extending horizontally about an entire outer circumferential perimeter of the body portion, and
(ii) at least one horizontal body rib spaced about the outer circumferential perimeter from the opposing grip areas, and

at least one vertical strut formed in at least one of the first side wall and the second side wall, the at least one vertical strut spaced from and having a length coextensive with a height of the opposing grip areas and configured to resist radially-inward distortion of the first and second side walls from gripping the opposing grip areas,

wherein the container exhibits approximately a 200% decrease in displacement of volume upon application of a force of 2.27 lbs. to at least one of the opposing grip areas compared to a substantially similar container without the strengthening features.
