Abstract
A fluid container is disclosed with a cap body made of rigid or semi rigid material and a valve body disposed within the cap body and movable between and open and closed position. The valve body is made of a semi flexible semi rigid material that has a coefficient of thermal linear expansion that is smaller than that of the cap body. The cap body and nozzle valve are configured with three different hermetic seals to counteract the effects of exposure to heat and cold over time and thereby extend the useful life of the cap and valve.
