发明名称 Snap fastener with tape, manufacturing method and mold
摘要 <p>A female member (11) of a snap fastener with tape comprising a female button (14) made of synthetic resin which is integrally molded on front and back faces of the tape (T) so as to hold a peripheral edge of an attachment hole (13) of the tape (T) having at least one attachment hole (13) and which has an engaging opening (14a) to be engaged with a male button (15) at a substantially center portion of the female button (14). The female button (14) has at least one mold hole (14b) extending in a front and back direction of the tape (T), and at least one portion of the tape (T) extends to an inside of the female button (14) across the mold hole (14b). At least one cut-out (14c) recessed in a diameter direction of the female button (14) is defined in a portion of an inner peripheral engaging face (14a') of the engaging opening (14a), and a gate burr (18) is formed at a bottom face (14c') of the cut-out (14c). Gate burrs (18) are not exposed on a surface, and the snap button can be easily manufactured without a special step for removing the gates (6), and the button can be firmly secured to the tape (T). <IMAGE></p>
