Abstract
Fastener stringer includes a fastener tape provided with a fastener element; and a stop part arranged at an end of the fastener tape. The stop part includes: a magnetic body; an encapsulating member encapsulating the magnetic body; and an injection-molded portion that at least partially covers or surrounds the encapsulating member encapsulating the magnetic body. At least the encapsulating member hinders heat from being transferred to the magnetic body while the injection-molded portion is formed.
Claims17
A fastener stringer comprising:
- a fastener tape provided with a fastener element;
- and
- a stop part arranged at an end of the fastener tape, wherein
- the stop part includes:
- a magnetic body;
- an encapsulating member encapsulating the magnetic body;
- and
- an injection-molded portion that at least partially covers or surrounds the encapsulating member encapsulating the magnetic body, and wherein
- at least the encapsulating member hinders heat from being transferred to the magnetic body while the injection-molded portion is formed.
A slide fastener comprising:
- first and second fastener stringers, the first fastener stringer including a first fastener tape provided with a first fastener element, and a first stop part provided at an end of the first fastener tape, and the second fastener stringer including a second fastener tape provided with a second fastener element and a second stop part provided at an end of the second fastener tape and adapted to configure a stop together with the first stop part;
- and
- a slider adapted for engaging and disengaging the first and second fastener stringers, wherein
- the first stop part includes a first magnetic body, a first encapsulating member encapsulating the first magnetic body, a first injection-molded portion that at least partially covers or surrounds the first encapsulating member encapsulating the first magnetic body, and at least one sloped surface that approaches the first encapsulating member as extending along a circumferential direction about an axis on which N-pole and S-pole of the first magnetic body are aligned, and wherein
- the second stop part includes a second magnetic body a second encapsulating member encapsulating the second magnetic body, a second injection-molded portion that at least partially covers or surrounds the second encapsulating member encapsulating the second magnetic body and at least one sliding portion that slides on the sloped surface in accordance with magnetic attraction effected between the first and second magnetic bodies.
A method of producing a fastener stringer that comprises a fastener tape provided with a fastener element, and a stop part arranged at an end of the fastener tape, the method comprising:
- encapsulating a magnetic body in an encapsulating member;
- and
- performing injection-molding in a condition where the encapsulating member, by which the magnetic body is encapsulated, and a portion of the fastener tape are arranged in a mold-cavity of a mold, wherein
- at least the encapsulating member hinders heat from being transferred to the magnetic body during the injection molding.
