Abstract: A container for transferring a liquid from one container or reservoir to another and comprising a bellows-type body having a closed bottom plate and a pair of outlet ports in the proximity of the upper end thereof, a tube extending through one of the outlet ports and having one open end disposed in the interior of the container and the opposite open end adapted for insertion with a liquid reservoir, a double seated valve provided in the other of said outlet ports to control the passage of air into and out of the interior of the container, the bellows-type construction of the container providing an automatic siphoning action for withdrawing liquid from the reservoir into the container, or permitting a manual pumping action for transferring the liquid from the reservoir into the container and ultimately emptying the liquid from the container, the transfer processing being accomplished in a manner substantially precluding contact between the liquid and the atmosphere surrounding the liquid transfer container.
