SURFACE FASTENER AND BAG BODY

摘要

A set of engagement members (101, 102) which each comprise a base sheet (10) and an assembly (50k) of J-shaped hooks (50), each of the J-shaped hooks (50) having an upstanding section (50a) which rises from the main surface (10a) of the base sheet (10) and also having an arch section (50b) which extends in an arc shape from the upstanding section (50a). The assembly (50k) includes rows (FL) of J-shaped hooks, each of the rows (FL) comprising J-shaped hooks (50) arranged at predetermined intervals in the Y-axis direction. The rows (FL) of J-shaped hooks are arranged at predetermined intervals in the X-axis direction perpendicular to the Y-axis direction. J-shaped hooks (50) of one of the engagement members (101, 102) can be inserted between adjacent rows (FL) of J-shaped hooks of the other engagement member (102, 101). When engaging the engagement members (101, 102) of the set with each other, each of the J-shaped hooks (50) of the set of engagement members (101, 102) can fall elastically in the opposite directions in the X-axis direction and engage with each other.
