Abstract
A gas sterilization package component having (a) a gas diversion wall stock for at least a portion of a container, the wall stock having an opening therethrough; (b) a gas diversion layer; (c) a filter sheet disposed between (a) and (b), the filter sheet having a first surface and an opposing second surface circumscribed by a perimeter edge; and wherein the first surface of the filter sheet is attached to a surface of said gas diversion layer and the second surface of the filter sheet is sealed to a surface of the wall stock whereby an opening in the wall stock is covered by the filter sheet and a gas passageway is defined from the opening through a portion of the second surface of the filter sheet and extending through said filter perimeter edge.
Claims26
A gas sterilization package component comprising:
- (a) a gas diversion wall stock for at least a portion of a container, said wall stock having an opening therethrough;
- (b) a gas diversion layer;
- (c) a filter sheet disposed between (a) and (b), said filter sheet having a first surface and an opposing second surface circumscribed by a perimeter edge;
- wherein said first surface of said filter sheet is attached to a surface of said gas diversion layer and said second surface of the filter sheet is sealed to a surface of the wall stock whereby an opening in said wall stock is covered by said filter sheet and a gas passageway is defined from said opening through a portion of said second surface of said filter sheet and extending through said filter perimeter edge or a distal portal area of said filter sheet.
A radial filter vent comprising:
- (a) a first gas diversion layer having an opening therethrough;
- (b) a second gas diversion layer,
- (c) a filter sheet disposed between (a) and (b), said filter sheet having a first surface and an opposing second surface circumscribed by a perimeter edge;
- wherein said first surface of said filter sheet is sealed to a first surface of said second gas diversion layer and said second surface of the filter sheet is sealed to a first surface of said first gas diversion layer whereby an opening in said first gas diversion layer is covered by said filter sheet and a gas passageway is defined from said opening through a portion of said second surface of said filter sheet and extending through said filter perimeter edge or a distal portal area of said filter sheet.
A radial filter vent comprising:
- (a) a gas diversion layer;
- (b) a filter sheet sealed on its first side to said gas diversion layer, said filter sheet having a first surface and an opposing second surface circumscribed by a perimeter edge;
- (c) a pattern applied pressure sensitive adhesive coating on said second side of said filter sheet, said adhesive coating having an opening area which is adhesive free circumscribed by adhesive;
- and
- (d) a release liner attached to said pressure sensitive adhesive coating on a side opposite from said filter sheet;
- wherein said second surface of the filter sheet is adapted for sealable attachment to a first surface of a second gas diversion layer whereby an opening in said gas diversion layer is covered by said nonadhesive opening area of said filter sheet and a gas passageway is defined from said opening area through a portion of said second surface of said filter sheet and extending through said filter perimeter edge or a distal portal area of said filter sheet.
