a. attaches at a flap peripheral edge to a panel peripheral edge of a front panel of the pouch,

b. has a covering pouch portion covering a covered portion of the front panel of the pouch that has more than about 50% of its perimeter of the flap peripheral edge detached from the front panel of the pouch, and

c. is configured to tuck or fold into the ostomy pouch to maintain a stoma viewing position without continuously contacted by an opening force or mechanism.

7. The ostomy pouch of claim 6, wherein the flap attached at the flap peripheral edge to the panel peripheral edge of the front panel of the pouch has more than about 65% of its perimeter detached from the front panel of the pouch.

8. The ostomy pouch of claim 6, wherein the flap attached at the flap peripheral edge to the panel peripheral edge of the front panel of the pouch has more than about 80% of its perimeter detached from the front panel of the pouch.

9. The ostomy pouch of claim 6, wherein the flap reveals more than 60% of the covered portion of the front panel of the pouch when manually manipulated to the stoma viewing position by 2 or fewer digits of a hand.

10. The ostomy pouch of claim 6, wherein the flap reveals more than 70% of the covered portion of the front panel of the pouch when manually manipulated to the stoma viewing position by 2 or fewer digits of a hand.

11. The ostomy pouch of claim 6, wherein the flap reveals more than 75% of the covered portion of the front panel of the pouch when manually manipulated to the stoma viewing position by 2 or fewer digits of a hand.

12. The ostomy pouch of claim 6, wherein the stoma viewing mechanism can conceal and or hide the stoma and the pouch contents as needed.

13. The ostomy pouch of claim 6, wherein the flap is held closed by adhering to the front panel of the pouch via a pressure sensitive adhesive, hook and loop, or a sleeve mechanism.

14.
