PURPOSE: A pack for refilling grease useable in a grease pump is provided to have a specified structure to promptly and easily charge the grease into the pump and to minimize amount of the grease discarded without complex operations. CONSTITUTION: The pack is a soft vinyl formed device containing grease within an inner hollow portion and has at least one of grease discharging ports projected at desired position on upper side of the pack to be cut. The pack can be received into a main body of the pump. A cavity(52) for discharging the grease is passed through the refill pack(50) at its upper side and is attached by a tape(53). Alternatively, the pack can be formed as a circular plate having inflow cavity passing through the pack and a perforated plate for discharging the grease instead of the grease discharging port or cavity.
