  • 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: 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: 11786016
    Abstract: A coil-shaped fastener element is sewn to a fastener tape without using a core string. An upper leg portion of the fastener element has a first upper surface continued from a connecting portion and contacting a sewing thread, and a second upper surface extending and sloping upward from the first upper surface via a bent portion. A height dimension between a top end surface and the bent portion of the upper leg portion is 20% or larger of a height dimension of the fastener element. The upper leg portion has a first lower surface which is sloped to be apart from the fastener tape toward a coupling head portion, and the upper leg portion has an element contacting portion in an area of the first lower surface. Thereby, cost reduction of the slide fastener can be attained, and the fastener element can be prevented from passing through the sewing thread and exiting.
