Quick-sealing design for radiological containment

A sealing assembly suitable for joining two elongated edges of flexible sheet material to form a hermetic barrier in the plane of said flexible sheet material, comprising:

• an elongated slide zipper type mechanical fastener having elongated edges and opposing engaging members affixed at a predetermined distance from each of said elongated edges, the respective elongated edges overlapping upon engagement of said mechanical fastener to form first and second flaps;
• a first adhesive layer formed along the elongated edge of said first flap;
• a second adhesive layer formed along the elongated edge of said second flap;
• a slide zipper having an inverted block "S" cross-sectional configuration including an upper plate, a center plate running along a portion of the slide terminating in a back edge which is configured to permit peel-off strips to slide smoothly over said back edge, and a lower plate, and a longitudinal configuration having a head portion and a tail portion, the head portion being sufficiently wide to accommodate said adhesive layers and the upper and lower plates extending past the center plate and necking down to form the tail portion of the slide;
• and
• peel-off strip means formed over each of said first and second adhesive layers prior to the formation of said barrier such that the slide zipper does not contact the adhesive layers;
• whereby said mechanical fastener and said first and second flaps combine along the adhesive layers thereof with opposite sides of said center plate to form said hermetic seal.
