I claim the ornamental design for an ostomy appliance seal, as shown and described.
FIG. 1 is a front perspective view of an ostomy appliance seal;
FIG. 2 is a top view thereof;
FIG. 3 is a bottom view thereof;
FIG. 4 is a cross sectional view thereof, taken along the indicia 4 shown in FIG. 2; and,
FIG. 5 is a front perspective view thereof showing the interior fingers of the ostomy appliance seal in a flexed position.
The evenly-spaced broken lines shown in FIGS. 1-5 illustrate portions of the ostomy appliance seal that form no part of the claimed design. The unevenly-spaced broken lines shown in FIGS. 1-5 illustrate boundary lines which form no part of the claimed design. In FIG. 2 indicia 4 shows where the cross section of FIG. 4 originates and forms no part of the claimed design.
