ABSTRACT:
The invention relates to a rotary canister base comprising a loudspeaker, a drinking pipe and an air-intake pipe, wherein the loudspeaker serves as a communicating tool and the drinking pipe, which may be connected to a canteen, are all arranged within the confined space of the canister base. In addition, the drinking pipe, when unused, may be fixed onto the canister base. Most importantly, the air-intake pipe connected to the canister can be rotated and positioned at different angles so that the wearer may adjust the direction of the canister to avoid interference with the ambient space when fleeing for life.
