First Claim
1. A vented colostomy pouch comprising in combination:
- an envelope-like container of thin, flexible waterproof material having a pair of opposite sides and upper and lower portions;
a waste aperture adapted to receive waste matter from a wearer;
a vent aperture extending through one of said sides at a location in the upper portion of said container;
an open-centered generally annular member secured to an exterior surface of said one of said sides in a position generally encircling said vent aperture to form a vent opening; and
a plug-type closure member releasably and removably retained within said annular member to seal said vent opening, such that removal of said closure member vents the interior of said container through said opening and replacement of said closure member closes and reseals said opening.

Abstract
A vented colostomy pouch includes a water proof bag having a waste aperture and a vent aperture, with an annular member being secured to the vent aperture and a plug type closure being removably connectable to the annular member to seal the vent opening. The plug and annular member are integrally formed as a unitary member from a plastic material with a flexible attachment interconnecting the annular member and plug. The attachment is deflectable to permit the plug to be inserted and removed from the annular member. The plug has cylindrical side walls that resiliently fit into mating sidewalls in the annular member, with sidewall friction being sufficient to prevent dislodgment without manually moving the plug. The plug is at least slightly longer than the annular member so that the plug clears the opening in the annular member when fully inserted.

7. A vented colostomy pouch comprising in combination:
-
an envelope-like container of thin, flexible waterproof material having a pair of opposite sides and upper and lower portions; a waste aperture adapted to receive waste matter from a wearer; a vent aperture extending through one of said sides at a location in the upper portion of said container; an open centered generally annular member secured to said one of said sides in a position generally encircling said vent aperture to form an enlargement thereof constituting a vent opening, said annular member including a central generally tubular portion for receiving a closure member and a thin skirt portion extending radially from said tubular portion, the skirt portion being attached to said one of said sides so as to secure the annular member to said one of said sides of said container; a plug-type closure member releasably and removably retained within said annular member to seal said vent opening such that removal of said closure member vents the interior of said container through said opening, and replacement of said closure member closes and reseals said opening; and an attachment between said closure member and said generally annular member, whereby each of said members is part of a unitary element, said attachment being flexible in at least selected areas to permit movement of said closure member outward and away from said generally tubular portion by flexing of said at least selected areas. - View Dependent Claims (8)

9. A vented colostomy pouch comprising in combination:
-
an envelope-like container of thin, flexible waterproof material having a pair of opposite sides and upper and lower portions; a waste aperture adapted to receive waste matter from a wearer; a vent aperture extending through one of said sides at a location in the upper portion of said container; an open centered generally annular member secured to one of said sides in a position generally encircling said vent aperture to form an enlargement thereof constituting a vent opening; said annular member including a central generally tubular portion for receiving a closure member and a thin skirt portion extending radially from said tubular portion, the skirt portion being attached to said one of said sides so as to secure the annular member to said one of said sides of said container; and a plug-type closure member releasably and removably retained within said annular member to seal said vent opening such that removal of said closure member vents the interior of said container through said opening and replacement of said closure member closes and reseals said opening said closure member having an effective length which is at least slightly greater than the axial length of said tubular member, whereby said closure member extends at least slightly through and beyond said tubular member when fully inserted therein. - View Dependent Claims (10)

11. A colostomy pouch comprising:
-
an enclosed bag formed of a waterproof flexible sheet material, the bag having an inlet opening that is adapted to be mounted over an opening in a user'"'"'s body for receipt of bodily waste into the bag, the bag also having a vent aperture through the sheet material; a manually operable vent mechanism for the pouch comprising; an annular member sealingly mounted on the bag over the vent aperture, the annular member including a vent opening therethrough in communication with the vent aperture, with a resilient peripheral surface of the annular member surrounding the vent opening; a plug that sealingly engages the vent opening from an exterior side thereof, the plug resiliently engaging the peripheral surface of the annular member with a frictional fit that resists axial dislodgment of the plug, the frictional fit between the plug and annular member being sufficiently secure that the plug remains in sealing engagement with the annular member until it is manually removed, the plug having a gripping portion thereof that can be manually manipulated to remove the plug from the opening in the annular member for venting the bag. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
