  • Patent number: 11109649
    Abstract: There is provided a fastening tape. A plurality of fastening cells on a surface of an elongated substrate. Each of at least some of the fastening cells includes: a fastening element array; one or more barriers at least partially surrounding the fastening element array; at least one slit provided in an upper portion of at least one of the one or more barriers; and a fastening element at least partially filling the slit. At least some of the fastening cells which are adjacent to each other in a longitudinal direction are separated from each other by an open space extending across the substrate in a lateral direction. The fastening element extends inward of the respective fastening cells in a direction away from a respective one of the open spaces.

  • Patent number: 11051590
    Abstract: 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.

  • Patent number: 10327518
    Abstract: A molded surface fastener, in which many magnetic particles can be contained in a closer part with respect to a magnet of a molding die, and further a front surface and a rear surface can be easily identified, is provided. In the molded surface fastener of the invention, a magnetic region containing magnetic particles is formed on at least a part between right and left resin intrusion barrier portions, and a magnetic raised portion which is lower than engaging elements and contains the magnetic particles therein is disposed between the engaging elements adjacent in a length direction within the magnetic region.

  • Patent number: 10278876
    Abstract: A male surface fastener has a sheet having a main surface, and a group of engagement elements in which the engagement elements are regularly arranged, the engagement element having a pillar that stands on the main surface of the sheet and an engagement head that is expanded along the main surface from the top end of the pillar, wherein 0.05?S2/S1?0.15 is satisfied where S1 represents an area of the main surface which corresponds to a region in which the group of engagement elements is arranged, and S2 represents a sum of areas of the top surfaces of the engagement heads of the engagement elements of the group of engagement elements.
