Abstract A portable fluid container comprises a cylindrical housing with a gas induction means at the bottom thereof including a needle and a detachable cartridge holder which is capable of being threadably engaged on a valve socket of the gas induction means to cause the needle to pierce a cartridge carried by the holder and cause introduction into the housing of a pressure fluid contained within the cartridge. A cover is threadably mounted on the housing and carries a nozzle and a valve actuator by which the contents of the container can be dispensed.
