  • Patent number: 4398533
    Abstract: A drinking device for underwater divers enables divers to drink while engaged in diving to provide moisture in the mouth and lungs. The device includes a container with a chamber for holding liquid and a passage leading to the chamber. A valve opens and closes the passage. The container has a pressure compensator for equalizing pressure in the chamber with exterior hydrostatic pressure. In the method, liquid is placed in the chamber. The diver provides suction on the end of the tube to draw liquid past the valve, then closes the valve. This displaces air from the container for diving.
