Title:
SURFACE FASTENER WITH EXCELLENT TEMPORARY FIXING FUNCTION
Document Type and Number:
WIPO Patent Application WO/2012/014667
Kind Code:
A1
Abstract:
Disclosed is a surface fastener with a plurality of male engaging elements installed on the surface of a plastic substrate. Specifically disclosed is a molded surface fastener wherein the male engaging elements have a stem that rises from the plastic substrate and protrusions for engaging that protrude from the stem to the side. The ratio (D/H) between the height (H) of the engaging elements from the substrate and the length (D) from the peak of the engaging elements to the lower end section of the protrusions is 0.35-0.75 and the rate of substrate coverage by the engaging elements is 25%-45%. The disclosed male molded surface fastener is an improvement on surface fasteners, particularly male molded surface fasteners, that engage when simply overlapped which makes positioning extremely difficult. The disclosed male molded surface fastener almost never engages when positioning and has a high engaging force after final fastening.
