Abstract:
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 plastic housing and a ball disposed within an interior region of the housing, the plastic 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; the plastic housing having a tubular portion, an end portion, a ring-shaped tab portion, a sealing tab, and at least first and second retaining tabs, the tubular portion being centered about a longitudinal axis and having a first end and a second end; the end portion being disposed at the first end of the tubular portion and enclosing the first end, the end portion having a plurality of apertures extending therethrough that extend substantially parallel to the longitudinal axis; the first and second retaining tabs extending generally parallel to the longitudinal axis from the second end of the tubular portion, the first and second retaining tabs being 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, an outer diameter of the ring-shaped tab portion being greater than a distance from an outer surface of the first retaining tab to an outer surface of the second retaining tab; and the ball being configured to move within the interior region of the plastic housing between a first operational position and a second operational position, the ball configured to seal against the sealing tab of the plastic 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.
