## Abstract

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.

## Claims

### Claim 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 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; and
wherein the body portion comprises two or less body ribs.

### Claim 2 (depends on 1)

The container of claim 1, wherein the body portion further comprises a body rib.

### Claim 3 (depends on 2)

The container of claim 2, wherein the body rib is less than 65% the depth of the top rib.

### Claim 4 (depends on 2)

The container of claim 2, wherein the top rib has a greater depth with respect to a surface of the container than the body rib.

### Claim 5 (depends on 2)

The container of claim 2, wherein the top rib and the bottom rib have a greater depth than the body rib.

### Claim 6 (depends on 1)

The container of claim 1, wherein a cross-section of the body portion is substantially circular.

### Claim 7 (depends on 1)

The container of claim 1, wherein the body portion is substantially hourglass shaped.

### Claim 8 (depends on 1)

The container of claim 1, wherein an angle formed by the top rib is less than 75°.

### Claim 11 (depends on 1)

The container of claim 1, wherein the container is hot-filled.

### Claim 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 a body rib;
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 have a greater depth than the body rib.

### Claim 13 (depends on 12)

The container of claim 12 wherein a cross-section of the body portion is substantially circular.

### Claim 14 (depends on 12)
