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.
Claims26
A fastener strip for integration into a foam molded object, the fastener strip comprising:
- (a) a base made from a thermoplastic resin material and including two side edges extending along a length of the base and two ends extending across a width of the base;
- (b) hook fastening elements located between the side edges, the hook fastening elements made from the thermoplastic resin material;
- and
- (c) barriers extending along the length of the base, each barrier located between one of the side edges and the fastening elements, the barriers made from the thermoplastic resin, the barriers each including an outer portion including gaps arranged in a line along the side edge and an inner continuous portion;
- wherein the number of fastening elements extending in a row along the length of the base is less than the number of outer portion gaps of one of the barriers.
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.
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.
A fastener strip, comprising:
- a planar substrate made from a thermoplastic resin and including a first surface and a second surface opposite to the first surface;
- barriers erected on the first surface near left and right side edges along a length direction of the substrate;
- and a plurality of engaging elements disposed between the left and right barriers, in which
- each of the left and right barriers includes at least two vertical walls,
- the vertical wall positioned on the outermost side in a width direction includes a plurality of gaps provided at a predetermined pitch in the length direction, and
- wherein:
- at least two of the gaps are provided on the vertical wall which is positioned on the outermost side with respect to a region between the engaging elements adjacent in the length direction of the substrate.
