  • Patent number: 11944165
    Abstract: The molded surface fastener includes: a fastener member that has a plurality of engagement elements disposed upright on the first surface of a base portion, and a back member that is secured to the second surface of the fastener member and that is provided with a structure enabling passage of a synthetic resin. The base portion has a first base region of a predetermined thickness and a second base region formed to be thicker than the first base region, and the back member is secured to at least the second base region of the base portion. The adhesion strength of the back member to the fastener member is thus increased, enabling the back member to be held more firmly by the base portion.

  • Patent number: 11528966
    Abstract: This molded surface fastener includes: a base portion; right and left outer wall portions arranged on the upper surfaces of the base portion; a plurality of engaging elements arranged between the right and left outer wall portions; and right and left magnetic wall portions arranged between the outer wall portions and the engaging elements. This molded surface fastener is molded by melting and integrating first synthetic resin and second synthetic resin that contains magnetic particles. At least each upper end part of the outer wall portions is formed only of the first synthetic resin, while at least each upper end part of the magnetic wall portions is formed only of the second synthetic resin. Consequently, the right and left magnetic wall portions can be formed into predetermined shapes in a stable manner.

  • Patent number: 11445786
    Abstract: 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.

  • Publication number: 20220290706
    Abstract: The surface fastener includes a base portion, a fastener member that includes a plurality of engagement elements, and a masking member that is detachably held by the fastener member. The masking member covers an engaging area of the fastener member, at least a part of the engaging element is embedded in the masking member. A space portion is provided between the base portion and the masking member in the engaging area. Thus, a foam resin can be prevented from intruding the engaging area of the fastener member in foam-molding of the cushion body. The masking member is also easily peeled off from the fastener member after foam-molding.
