## Abstract

A vehicle battery pack container is provided. The container includes a base portion having an aperture extending therethrough, a peripheral wall coupled to the base portion, and a cover coupled to the peripheral wall. The container further includes a venting device having a housing and a ball disposed within an interior region of the housing. The housing is coupled to the base portion such that the venting device is in fluid communication with the aperture in the base portion. The ball seals against a sealing tab of the housing at a first operational position to prevent fluids from passing through the venting device into the container. The ball allows gases from the container to flow through the venting device when the ball is at a second operational position.

## Claims

### Claim 1

A vehicle battery pack container, comprising:
a base portion having an aperture extending therethrough;
a peripheral wall coupled to the base portion,
a cover coupled to the peripheral wall;
a venting device having a housing and a ball disposed within an interior region of the housing, the housing configured to be coupled to the base portion such that the venting device is in fluid communication with the aperture in the base portion; and
the ball being configured to move within the interior region of the housing between a first operational position and a second operational position, the ball configured to seal against a sealing tab of the housing at the first operational position to prevent fluids from passing through the venting device into an interior region of the vehicle battery pack container, the ball further configured to allow gases from the interior region of the vehicle battery pack container to flow through the venting device when the ball is at the second operational position.

### Claim 2 (depends on 1)

The vehicle battery pack container of claim 1, wherein the housing has a tubular portion, an end portion, a ring-shaped tab portion, the sealing tab, and at least first and second retaining tabs, the tubular portion being centered about a longitudinal axis.

### Claim 3 (depends on 2)

The vehicle battery pack container of claim 2, wherein the end portion is disposed at a first end of the tubular portion and encloses the first end of the tubular portion, the end portion having a plurality of apertures extending therethrough.

### Claim 4 (depends on 3)

The vehicle battery pack container of claim 3, wherein the ring-shaped tab portion extends around an outer surface of the tubular portion at a second end of the tubular portion and further extends radially outwardly from the outer surface.

### Claim 5 (depends on 4)

The vehicle battery pack container of claim 4, wherein the sealing tab extends around an inner surface of the tubular portion at the second end of the tubular portion and further extends radially inwardly from the inner surface.

### Claim 6 (depends on 2)

The vehicle battery pack container of claim 2, wherein the first and second retaining tabs extend generally longitudinally from the second end of the tubular portion.

### Claim 7 (depends on 2)

The vehicle battery pack container of claim 2, wherein the first and second retaining tabs are configured to be received through the aperture of the base portion such that the first and second retaining tabs are held against a first surface of the vehicle battery pack container and the ring-shaped tab portion is held against a second surface of the vehicle battery pack container.

### Claim 8 (depends on 2)

The vehicle battery pack container of claim 2, wherein the ball is configured to move within the interior region of the tubular portion between the first operational position and the second operational position.

### Claim 9 (depends on 1)

The vehicle battery pack container of claim 1, wherein the housing is constructed of at least one of plastic and rubber.

### Claim 10 (depends on 1)

The vehicle battery pack container of claim 1, wherein the ball is constructed of at least one of plastic and rubber.

### Claim 11 (depends on 1)

The vehicle battery pack container of claim 1, wherein the ball has a diameter less than an inner diameter of the housing.

### Claim 12 (depends on 1)

The vehicle battery pack container of claim 1, wherein the venting device is disposed within a region at least partially enclosed by a vehicle frame member.
