ABSTRACT:
A closure device or "zipper" particularly suitable for use with heavy water-tight containers to provide the secure joinder of an opening formed in the container and which can be readily separated to provide access to the interior of the enclosure and/or to permit removal thereof from the object the container is covering. The closure is formed from first and second pieces which are fabricated from a resilient material such as a suitable plastic, each of these pieces having an attachment flap at one end thereof which is secured to an edge portion of the enclosure which is to be joined to an adjacent such edge portion. One of these pieces has an upstanding elongated fastener strip with alternate rib and groove portions which run laterally from the main body of the strip. The second of these pieces has an upstanding riser portion which extends substantially normal from the flap portion, a head portion which runs from the top end of the riser portion substantially normal to the riser portion and a fastener strip which runs from the end of the head portion substantially normal thereto and opposite the riser portion, the riser and head portions and the fastener strip forming a cover for the closure device. The fastener strip of the second piece has elongated alternate ridges and grooves running normal to the main body of the strip similar to that of the first piece, the ridges of the strips of the first and second pieces interlocking together and fitted within the grooves to form a tight joint between the two pieces. A tool is provided to facilitate such joinder.
