Molding hook and loop fastener

摘要

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 includes a plurality of vertical walls disposed alternately. Between the two adjacent, rows of the vertical walls disposed alternately, each of the vertical walls disposed on one row is connected to two vertical walls disposed on the other row via a connecting part, and the connecting part connects one end portion of one vertical wall disposed on the adjacent row and the other end portion of the other vertical wall. 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 the connecting part, and flexibility of the molding hook and loop fastener can be improved.

主权项

1. A molding hook and loop fastener including:
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 rows of vertical wall arrays, the vertical wall array of each row includes a plurality of vertical walls that are disposed intermittently in the length direction and are alternately disposed between an adjacent vertical wall array, and the molding hook and loop fastener is molded integrally with a foam body at the same time as molding of the foam body, wherein: between two adjacent rows of vertical walls disposed alternately, each of the vertical walls disposed on one row is connected to two vertical walls disposed on the other row via connecting parts, and the connecting parts connect one end portion in the length direction of the vertical wall disposed on one of the adjacent rows and the other end portion in the length direction of the vertical wall disposed on the other row only, and the respective connecting parts are disposed separately and independently in the length direction of the substrate.
