  • Patent number: 8875933
    Abstract: A drainable container system for a vehicle includes a container having an exterior surface and defining an interior cavity configured for storing a fluid, and a drain hole configured for draining the fluid from the cavity. The hole has a central longitudinal axis that is substantially perpendicular to the surface. The system includes a drain plug, wherein the plug is insertable into the hole along the axis into a locked position so that the fluid does not drain, and removable from the hole along the axis when disposed in an unlocked position so that the fluid drains. The system includes a locking element configured for preventing rotation of the plug within the hole about the axis when the plug is disposed in the locked position, wherein the element is formed from a metal that is substantially elastic at a temperature of from about ?40° C. to about 10° C.
