Abstract: A liquid storage and delivery system for use with protective masks having hand-operable bulb siphon pumps in line with conduits extending from a canteen assembly to the drinking mouthpiece of the protective mask. The system includes structure to allow a user to drink directly from a central storage/dispensing reservoir by connecting the conduits directly thereto, and also allows the canteen assembly to be refilled from the reservoir while maintaining the system's protective integrity.

Abstract: A liquid storage and delivery system for protective masks has a hand-operable bulb siphon pump in line with conduits extending from a canteen assembly to the drinking mouthpiece of a protective mask. The canteen assembly includes structure adapted to flex in response to the partial vacuum created within the canteen assembly as liquid is withdrawn. An adapter may be used to enable use of the present system with prior art protective masks. A protective sheath covers at least a portion of the conduit to protect it against freezing, dirt, condensation, or physical damage.
