  • Patent number: 11877628
    Abstract: A watertight fastener includes a pair of fastener tapes; fastener elements provided on a side of one end edge part along a longitudinal direction of the fastener tapes; and a slider engaging and disengaging the fastener elements. On a surface of the fastener tapes opposite to the fastener elements, a waterproof seal layer is provided along the longitudinal direction at a position at which the fastener elements are provided. A width of the waterproof seal layer in a direction orthogonal to the longitudinal direction is narrower than a width of the slider. With the pair of fastener tapes being closed by engagement of the fastener elements, end parts of the waterproof seal layer close to the end edge parts of the fastener tapes come into contact with each other without overlapping in a thickness direction and without a gap to be in close contact in a liquid-tight manner.

  • Patent number: 11261306
    Abstract: The disclosure discloses a method for forming a rubber layer on a surface of a resin material. In the method, painting is first performed on the surface of the resin material to form a painting layer, using a paint to which a pigment has been added; then, rubber coating is performed to form a rubber layer on the painting layer. The method of the disclosure may be used in surface treatment of a fastener product. The disclosure further discloses a slide fastener, a buckle and a snap button using the method of the disclosure. The method of the disclosure may solve a conventional problem that a rubber coating is likely to fall off a resin surface, and the rubber on the surface of the resultant fastener product is less likely to fall off.

  • Patent number: 9480311
    Abstract: In a slide fastener, at least one stopping element including a resistance portion that increases sliding resistance by being brought into contact with an inner surface of a slider when the slider is sliding is locally disposed locally on an element row of a fastener stringer. Accordingly, the slider can be stopped at any position where the stopping element is disposed arbitrarily on the element row and an immobilized state of the slider can be maintained. By operating the slider with a force greater than the sliding resistance to the stopping element, the slider can be made to ride over the resistance portion of the stopping element and to slide along the element row.
