Abstract
An ostomy appliance (10) includes an outer wall (12) having first and second opposed sidewalls (14, 16) joined at an outer periphery (18), an inlet opening (22) and a filter (24). The outer wall (12) defines an interior volume (20) having a collection area. The ostomy appliance (10) further includes a fastener (32) on an external surface (30) of the outer wall (12). The fastener (32) is movable between a released state in which the ostomy appliance (10) is in an unfolded state, and a fastened state in which the ostomy appliance (10) is a folded state. The ostomy appliance (10), in the folded state, further includes a crease (40) positioned between the inlet opening (22) and the filter (24).
