Abstract
A coolant container cap assembly for use with a coolant container having first and second sealing ridges. The cap assembly comprises an exterior cover for removeably securing the cap assembly to the container. A valve housing member is rotatably secured to the cover and has a lower housing portion and an upper housing portion. A first sealing gasket is mounted to the lower housing portion for selectively engaging and sealing the cap assembly with the first sealing ridge of the container. A second sealing gasket is mounted to the upper housing portion for selectively engaging and sealing the cap assembly with the second sealing ridge of the container. The assembly is characterized by an adjustment device mounted to the upper housing. The adjustment device allows relative movement of the first sealing gasket with respect to the second sealing gasket. Specifically, the adjustment device permits the first sealing gasket to detach from the first sealing ridge of the container while maintaining the sealing engagement of the second sealing gasket with the second sealing ridge of the container.
