Vacuum resistant ribs for lightweight base technology containers
View Patent ↗A hot-fillable container that is cylindrical in shape. The container may have two ribs. A top rib is located in the top bumper and a bottom rib is located in the bottom bumper. Both the top and the bottom ribs have depth that is deep enough so that the container may withstand the hot-fill process and increase its top load ability.
1. A container comprising:
a finish connected to a neck;
a top portion located below the neck;
a top bumper portion located below the top portion;
a top rib located within and extending about an entire outer circumferential perimeter of the top bumper portion and having a depth with respect to the circumferential perimeter of the top bumper portion;
a body portion located below the top bumper;
a bottom bumper located below the body portion and above a base portion of the container, wherein the bottom bumper comprises a bottom rib extending about an entire outer circumferential perimeter of the bottom bumper and having a depth with respect to the circumferential perimeter of the bottom bumper; and
wherein the body portion comprises at least one body rib extending about an entire outer circumferential perimeter of the body portion, each body rib having a depth with respect to the circumferential perimeter of the body portion, the top rib and the bottom rib each having a greater depth than each body rib.
2. The container of claim 1 , comprising one body rib.
3. The container of claim 1 , wherein each body rib is less than 65% the depth of the top rib.
4. The container of claim 1 , wherein the top rib and the bottom rib each has a greater depth than each body rib.
5. The container of claim 1 , wherein a cross-section of the body portion is generally circular.
6. The container of claim 1 , wherein the body portion is generally hourglass shaped.
7. The container of claim 1 , wherein the top rib and bottom rib have substantially equal depths.
8. The container of claim 1 , wherein the top rib and the bottom rib are located equidistantly from a longitudinal axis A of the container.
9. The container of claim 1 , wherein an angle formed by the top rib is less than 75°.
10. The container of claim 1 , wherein the container is hot-filled.
11. The container of claim 1 , wherein the container includes two body ribs.
12. A hot-fillable container comprising:
a top portion having a first radius with respect to a longitudinal axis greater than any radius on a body portion;
the body portion located below the top portion, wherein the body portion comprises at least one body rib extending about an entire outer circumferential perimeter of the body portion;
a base portion having a second radius with respect to the longitudinal axis greater than any radius on the body portion; and
wherein the top portion comprises a top rib and the base portion comprises a bottom rib, wherein the top rib and the bottom rib each has a greater depth with respect to an outer circumferential perimeter proximate thereto than each body rib.
13. The container of claim 12 wherein a cross-section of the body portion is generally circular.
14. The container of claim 12 , wherein the body portion is generally hourglass shaped.
15. The container of claim 12 , wherein an angle formed by the top rib is less than 75°.
16. The container of claim 12 , wherein the top rib and bottom rib each has substantially equal depths.
17. The container of claim 12 , wherein the top rib and the bottom rib are located equidistantly from a longitudinal axis A of the container.
18. The container of claim 12 , comprising one body rib.
19. The container of claim 12 , wherein the container includes two body ribs.
20. The container of claim 12 , wherein the base portion comprises a bottom surface extending into a cavity of the container.
21. The container of claim 20 , wherein the bottom surface extends from a bottom rim into the cavity of the container a distance D 1 , and the distance D 1 is equal to a distance D 2 from the bottom rim to the bottom rib.
