Claim:
1. A drainable ostomy pouch comprising a proximal and a distal side wall each including a liquid and gas impermeable film, said films being sealed to each other for defining: i) a cavity formed of said films for receiving human stomal discharge through an aperture in said proximal side wall and ii) an elongate drainage portion formed of said films in communication with said cavity and extending downwardly from said cavity in a longitudinal direction thereof, said elongate drainage portion ending in a drainage opening defined by lower ends of said films extending transversely to said longitudinal direction, a proximal and a distal flexible stiffening strip of relatively stiff material on said elongate drainage portion and being attached externally on said films to the outer surface of said proximal and distal side walls, respectively, of said drainage portion, the pouch further comprising a flap of flexible material having an edge portion attached to one of said side walls in spaced relation to said proximal and distal stiffening strips, said flap of flexible material having a first securing strip of an interlocking means attached on an unsecured portion of said flap that can be rotated relative to said one of said side walls about an angle formed between said edge portion and the remainder of said flap, and a second securing strip of a corresponding interlocking means attached to the other of said side walls intermediate said proximal and distal stiffening strips and said flap of flexible material for securing a coil comprised of: i) each of said proximal and distal stiffening strips rotated upwards at least two times and ii) said coil fitting snuggly and tightly in said angle formed between said edge portion and the remainder of said flap with said interlocking means of said first and second securing strips in engagement, wherein the second securing strip is longitudinally spaced away from the proximal stiffening strip with a distance of at least a longitudinal width of the distal stiffening strip, such that the distal stiffening strip abuts an area of the distal side wall between distal stiffening strip and the second securing strip after the proximal and distal stiffening strips are rotated upwards once, wherein the first and second securing strips are the only means for securing the coil.
