Patent number: 12102193Abstract: A mesh hook surface fastener does not lose engagement ability even when subjected to mold-in forming and gives only a slight feeling of something foreign. The mesh hook surface fastener contains first shape holding ribs (a21) with a relatively small protrusion height and second shape holding ribs (a22) with a relatively large protrusion height which protrude to the opposite side of hook-shaped engagement elements (B1, B2) across a base layer (A1) and are alternately arranged. The heights of the adjacent shape holding ribs (a21, a22) are different, which prevents the direct entrance of a foamable resin liquid and weakens its force. As the force weakens, foaming and curing progress more readily and, as a result, the amount of the foamable resin liquid that passes through meshes of the base layer to reach the hook-shaped engagement elements can be reduced.Type: GrantFiled: October 22, 2020Date of Patent: October 1, 2024Assignees: KURARAY FASTENING CO., LTD., DELTA KOGYO CO., LTD.Inventors: Toru Tanokura, Yoshikatsu Fujisawa, Satoru Ono, Etsunori Fujita
