ABSTRACT:
An extruded plastic reclosable fastener strip has a base from which extends a stem and a resiliently flexible, foldable hook flange projecting in normal position obliquely from the distal end of the stem toward, but spaced from, a stiff backup shoulder rib extending from the base in the same direction as, and substantially spaced from, the stem. The rib is about the same length as the stem, and the spacing between the rib and the stem provides a groove socket of ample dimensions relative to the foldable hook flange and the stem so that in a fastener closing maneuver a hook flange and a stem of a complementary profile of a companion fastener strip can be received in assembly slidably between the rib and the foldable hook flange by folding of the foldable hook flange substantially completely toward the stem until the hook flanges pass one another and the foldable hook flange then snaps back to the oblique position for interlocking with the profile hook flange of the companion fastener strip in a manner to resist separation of the interlocked strips due to twisting distortions.
