A container for dispensing a refrigerant as a liquid under pressure includes a vessel for holding the refrigerant. The bladder in the vessel has a relatively small amount of a liquid having a higher vapor pressure greater than the vapor pressure of the refrigerant. The bladded has flexible walls so that the vaporized pressurizing fluid expands the bladder walls to pressurize the refrigerant in the first container. The pressure maintains the refrigerant as a liquid under pressure as refrigerant is dispensed from the vessel. A channel member may also be provided within the vessel for channeling liquid refrigerant between regions of the vessel if the bladder or the collapsing vessel blocks a portion of the inside of the vessel. Alternatively, the bladder surrounds the vessel. The bladder and vessel are within an outer container. As the bladder expands, it collapses the walls of the vessel when refrigerant is dispensed from the first container.
