Abstract
This invention disclosed herein relates to a pump apparatus for use with a liquid container for transferring liquid from a liquid container. It comprises a pump means comprising a manually-operable pump for pumping liquid and formed with a pump chamber through which liquid can be pumped by the pump. It also has an inlet opening for receiving liquid into the pump chamber and an outlet opening for dispensing liquid out of the pump chamber when liquid is pumped through the chamber using the pump. There is a coupling means for mounting the pump means to the opening of a liquid container to permit the gravitational flow of liquid into the pump chamber through the inlet opening when the mounted pump means is placed on ground level and the pump pumped.
