A zipper includes a tape body including two zipper tapes each having an inner edge with a row of teeth. A stop includes a first end connected to distal ends of the rows of teeth and receives two first conductive plates. An end of one of the two first conductive plates is electrically connected to an electrode of at least one light-emitting element. A power connecting portion is electrically connected to another of the two first conductive plates and another electrode of the at least one light-emitting element. A slider is slidably disposed on the rows of teeth for engaging or disengaging the rows of teeth. The slider includes a second conductive plate configured to simultaneously contact with the two first conductive plates, causing electrical conduction to activate the at least one light-emitting element to emit light. A container with the zipper is also provided.

These fastener elements have: an element main body portion having a coupling head portion; and first and second projections that project in a tape surface/rear-surface direction from the element main body portion. The first and second projections have a top surface, peripheral side surfaces standing upright from the element main body portion, and at least one sloped surface between the top surface and the peripheral side surfaces that has a different angle of inclination from the top surface and the peripheral side surfaces. As a result, the fastener elements appear long and narrow in the element length direction and have an external appearance close to that of a metal element. Furthermore, a stop claw portion is less likely to catch on the fastener elements when starting the sliding operation of a slider.

A fastener element has a central land portion and first and second bulging portions bulging from the central land portion toward the tape front surface side and the tape rear surface side in the element thickness direction. The first and second bulging portions respectively have a bulging end surface facing to the element thickness direction. The bulging end surface has a quadrilateral base end surface which is long in the element length direction and a tapered protrusion end surface protruding from the base end surface in the element width direction. Thus, it is possible to make the fastener element look like a single-sided metal element and to make a slide fastener which is formed by using the fastener elements lighter than a conventional slide fastener having single-sided metal elements.

Provided is a copper alloy fastener element which improves season cracking resistance by a means different from that of increasing a ratio of a β phase. The copper alloy fastener element includes a copper-zinc alloy as a base material, the base material having: an apparent zinc content of from 34 to 38%; a dendrite structure; and a β phase at a ratio of 10% or less.

A fastener stringer includes a row of elements on which cured coating film is formed at sites where it is difficult to be coated by a roll coating method, preferably over the entire exposed surface, without incorporating any conductive wire in a fastener tape. A fastener stringer includes a row of elements and a fastener tape, at least one side edge of the fastener tape having insulation properties, the row of the elements being attached to the one side edge of the fastener tape, wherein each element includes a pair of leg portions and a head portion, the head portion having an engaging region for engaging with an opposing element when constructing a fastener chain, and wherein cured coating film is formed at least at a center portion in a front and back direction of the fastener tape on an end surface of the head portions.

A first stop member includes a first base and a first insert that is positioned between the first base and a first fastener element and is inserted into the slider via a rear mouth of a slider. A second stop member includes a second base and a second insert that is positioned between the second base and a second fastener element and is inserted into the slider via a second slit of the slider. The second insert moves toward the second slit of the slider in accordance with at least one or respective rotations of the first and second bases. A rotational axis with respect to the at least one or respective rotations of the first and second bases is positioned between the first tape region and the second tape region.

Slide fastener (1) includes a pair of fastener stringers (2), at least one slider (5) for opening and closing the pair of fastener stringers (2), and a stop member (6,7) attached to a side-edge (32) of a fastener tape (3) at a position adjacent to the series of fastener elements. The stop member (6,7) has at least one thinned portion (61,71) having a thickness lesser than a thickness of the fastener element (4) and/or at least one through-hole (68) extending through the stop member (6,7) in an up-down direction. The thinned portion (61,71) and/or the through-hole (68) is configured to allow the stop member (6,7) to be produced by remolding one or more fastener elements (4). Alternative conditions are also disclosed.
