Abstract: Liquid transfer apparatus transfers liquid between containers, and includes a liquid storage chamber having an inlet and an outlet; a pump chamber having an inlet and an outlet; a passage connecting the storage chamber outlet to the pump chamber inlet; a suction pump mechanism for sucking air from the storage chamber via the pump chamber inlet; and a valve for selectively opening and closing the inlet of the liquid storage chamber, allowing liquid to flow into the storage chamber by a pump and opening of the inlet. A carry case stores the liquid transfer apparatus and three different adaptors, which can be connected to an aperture of a container for use with a liquid transfer apparatus. One adaptor has a radially adjustable thread engaging components to enable the adaptor to be connected to different sized apertures.
