Patent number: 11445786Abstract: A fastening tape having flexibility in a longitudinal direction of the fastening tape. The fastening tape includes a plurality of fasteners, a support, and magnetic material positioned on the support. The support defines a plurality of plateaus and a plurality of valleys. The magnetic material is positioned on at least a portion of one of the plurality of plateaus or the plurality of valleys of the support such that a height of the magnetic material varies in the longitudinal direction. Because the height of the magnetic material varies, the fastening tape is more flexible in the longitudinal direction. In some cases, the fastening tape is also flexible in the lateral direction.Type: GrantFiled: December 18, 2019Date of Patent: September 20, 2022Assignee: YKK CorporationInventors: Zhiyu Ren, Tsuyoshi Minato, Atsushi Nakaya, Kenta Okada

Patent number: 11051590Abstract: The molded surface fastener has a base portion, right and left resin-intrusion-preventing wall portions standing on the base portion, and a plurality of engaging elements disposed between the right and left resin-intrusion-preventing wall portions. The resin-intrusion-preventing wall portions contain magnetic particles, and at least a part of a region formed of the resin-intrusion-preventing wall portions and the base portion has a concentration gradient portion in which a concentration of the contained magnetic particles is decreased toward at least one direction. This makes it possible to enhance the adhesion property between the part containing the magnetic particles and the part substantially containing no magnetic particles, and to suppress occurrence of cracks or the like between the containing part and the non-containing part of the magnetic particles at the time of manufacturing the molded surface fastener and at other times.Type: GrantFiled: February 19, 2016Date of Patent: July 6, 2021Assignee: YKK CorporationInventors: Hiromasa Abe, Ayumi Fujisaki, Kenta Okada
