Abstract
In a structure of the surface fastener of this invention, a substrate sheet has on its surface a plurality of dimples each defining a hollow large enough to receive a companion loop, and engaging elements are integrally molded and stand from the bottom surface of the dimple. With the surface fastener of this invention, the height of the hooks in appearance is short and the flexibility of the molded surface fastener is secured, and the hooks are prevented from falling laterally and forwardly excessively so that an adequate degree of durability for repeated use can be achieved and the flexibility of the substrate sheet and reliability of molding can be improved while securing engaging strength and a high rate of engagement with a loop of the companion surface fastener.
Claims12
A molded surface fastener comprising a substrate sheet and a multiplicity of side-by-side rows of engaging elements, for engaging loops, molded on and projecting from one surface of said substrate sheet,
- wherein said substrate sheet has in said one surface a corresponding number of dimples respectively associated with each of said engaging elements, and each of said engaging elements has a stem rising from a bottom surface of the associated dimple, and a loop engaging portion formed at a distal end of said stem such that the height of said engaging elements above said one surface is less than the designed height for said engaging elements.
