ABSTRACT:
A flask for attachment to a life preserver is provided with a coiled straw inside the flask. The flask is covered by a cap through which the end portion of the straw is adapted to extend. The cap has a valve mechanism which is attached to the end portion of the straw and pinches the end portion of the straw shut to prevent the entrance of sea water in the flask. A spring is attached to the valve mechanism in such a way that some force is required to actuate the valve mechanism so it no longer pinches the end portion of the straw shut. When this force is exerted on the spring, the valve mechanism releases the end of the straw so the person in the water can suck the contents of the flask through the straw. If the person in the water faints and no longer exerts this force on the valve mechanism, the spring automatically actuates the valve mechanism to pinch the end portion of the straw shut, to prevent the entrance of sea water into the flask and thus preserve its contents.
