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.
Claims16
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, 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;
- and
- wherein a dimension of the vertical wall portions in the length direction at a predetermined height position is equal to or smaller than a dimension of the gaps in the length direction at the predetermined height position.
