Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
216 words
A closure assembly for releasably joining first and second sheet members comprising a first angle strip member and a second angle strip member, each strip member having flexible leg members and a groove defined at the intersection of the two leg members, the first angle strip member being secured to the first sheet member along one of its leg members and the second angle strip member being secured to the second sheet member along one of its leg members; a first tape member having a surface defined by a plurality of upstanding flexible hooking elements secured to the second leg of the first angle strip member; a second tape member having a surface defined by a plurality of upstanding flexible complimentary hooking elements secured to the second leg of the second angle strip member; a slidable closure member including guide means extending from the closure member into the grooves in the angle strip members for sliding therein, the guide means forcing the tape members into face-to-face engagement causing a large number of hooking elements on the first tape member to engage a large number of complimentary hooking elements on the second tape member when the slidable closure member is traversed in a closing direction; and means for disengaging the hooking eLements from the complimentary hooking elements.
