Abstract

Provided is a molding hook and loop fastener, in which a barrier erected near left and right side edges of a substrate includes at least two rows of vertical wall arrays, and the vertical wall array positioned on the outermost side includes a plurality of gaps provided at a predetermined pitch in a length direction. At least two of the gaps are provided on the vertical wall array positioned on the outermost side with respect to a region between the engaging elements adjacent in the length direction of the substrate. Due to this, in the molding hook and loop fastener, an outer side and an inner side of the barrier can be divided by the vertical wall array, and flexibility of the molding hook and loop fastener can be improved.

First claim

1 . A fastener strip for integration into a foam molded object, the fastener strip comprising:
(a) an array of hook fastening elements made from thermoplastic resin material, the hook fastening elements arranged in several rows extending along a length of the fastener strip; and (b) barriers extending along at least two sides of the fastener strip, the hook fastening elements located between the barriers, the barriers made from the thermoplastic resin, the barriers each including at least one row of peaks and troughs extending along the length of the fastener, the peaks being at least as high as tops of the hook fastening elements; wherein the troughs in the barriers are spaced sufficiently close together such that, relative to the outermost rows of the fastening elements next to each of the barriers, a bottom of at least one of the troughs is positioned between each of the fastening elements.

2 . The fastener strip of claim 1 , wherein the at least one row of peaks and troughs comprises at least two rows of peaks and troughs for each of the barriers.

3 . The fastener strip of claim 1 , wherein the troughs narrow as they extend downwardly from the peaks.

4 . A fastener strip for integration into a foam molded object, the fastener strip comprising:
(a) an array of hook fastening elements made from thermoplastic resin material, the hook fastening elements arranged in several rows extending along a length of the fastener strip; and (b) barriers extending along at least two sides of the fastener strip, the hook fastening elements located between the barriers, the barriers made from the thermoplastic resin, the barriers each including at least one row of peaks and troughs extending along the length of the fastener, the peaks being at least as high as tops of the hook fastening elements; wherein the peaks in the barriers are spaced sufficiently close together such that, relative to the outermost rows of the fastening elements next to each of the barriers, a top of at least one of the peaks is positioned between each of the fastening elements.

5 . The fastener strip of claim 4 , wherein the troughs narrow as they extend downwardly from the peaks.

6 . The fastener strip of claim 5 , further comprising gapped lateral wall portions extending between the barriers across a width of the fastener strip.

7 . The fastener strip of claim 6 , wherein the gapped lateral wall portions define gaps that are narrower than the gaps of the barriers.

8 . The fastener strip of claim 6 , wherein groups of the gapped lateral wall portions are positioned along the length of the base.

9 . The fastener strip of claim 4 , wherein the at least one row of peaks and troughs comprises at least two rows of peaks and troughs for each of the barriers.
