We claim the ornamental design for a refrigerator internal liquid dispenser, as shown and described.
FIG. 1 is a perspective view of a refrigerator internal liquid dispenser showing our new design in its environment and not to the same scale as that shown in FIGS. 2 to 7;
FIG. 2 is a second perspective view of the refrigerator internal liquid dispenser showing our new design;
FIG. 3 is a front view of the refrigerator internal liquid dispenser of FIG. 2;
FIG. 4 is a left side view of the refrigerator internal liquid dispenser of FIG. 2;
FIG. 5 is a right side view of the refrigerator internal liquid dispenser of FIG. 2;
FIG. 6 is a top view of the refrigerator internal liquid dispenser of FIG. 2; and,
FIG. 7 is a bottom view of the refrigerator internal liquid dispenser of FIG. 2.
The broken lines in FIG. 1 are included for the purpose of illustrating the environment of use of the refrigerator internal liquid dispenser. The broken lines in FIG. 1 represent the environment. None of the broken lines form a part of the claimed design. The back view of the refrigerator internal liquid dispenser does not include any elements that form the ornamental design for the refrigerator internal liquid dispenser, and is therefore not included.
