The apparatus includes a deformable transport container having an opening for receiving the refill liquid and an adaptor including an inlet, an outlet, and a passage extending between the inlet and the outlet. The inlet is removably receivable at the opening of the transport container such that when the inlet is received at the opening, the inlet is operable to receive a flow of the refill liquid through the opening from the transport container and to channel the flow through the passage to the outlet, the outlet being operable to dispense the refill liquid into the destination container, and when the inlet is not received at the opening, the transport container is operable to receive the refill liquid through the opening. Systems and methods for delivering refill liquid to a destination container are also disclosed.
