A liquid dispenser for a container which may have a flexible liner for holding liquid, for expelling the liquid therefrom. The dispenser is easily attachable to containers having a common inlet and outlet, and upon depression of a button will permit the liquid in the container to be dispensed from the normally closed dispenser outlet passage. A regulated source of pressurized gas is provided in the dispenser for assisting the flow of liquid if needed, as well as a safety pressure relief valve. The liner can be used when contact of the liquid with the pressurized gas is not preferred or permitted. In that case, the pressurized gas exerts pressure on the liner which forces the liquid out. Another feature is to provide an assembly for facilitating transfer of liquid into the container. This liquid transfer assembly easily connects with the container upon removal of the dispenser, for the smooth transfer of liquid into the container through a funnel-like member and includes an air passage for expelling air within the container prior to filling.
