A ZIP FASTENER AND AN APPLICATION OF A ZIP FASTENER

摘要

A zip fastener which comprises two support tapes (1,2), two rows of coupling elements (3,4), each row (3,4) being attached to its own support tape (1,2), a slider element (5) comprising a puller attachment point (6) and a tunnel (7) for each row of coupling elements (3,4), as well as a core part (8), which divides one end of the tunnel (7) into two tunnel branches (7a, 7b), in which the rows of coupling elements (3, 4) separated by the core part (8) slide when opening or closing the zip fastener. The slider element (5) includes slots (9, 10) connected to the tunnel (7), in which the support tapes (1, 2) can slide when the slider element (5) is moved to open or close the zip fastener. One (10) of the slots (9, 10) in the slider element (5) is on the same or on the opposite side as the puller attachment point (6). The freely extending lip (11, 15) of the sliding support tape (2) extends from the slot (10) over the slider element (5) in such a way that when the zip fastener is closed, the lip (11) extends to cover the seam point (14) between the coupling element rows (3, 4). In this way, the seam point can be protectively covered without forming lips or projections jamming between the coupling elements.
