A zipper lock contains: a first zipper slider, a second zipper slider, a locking device, a first locking element, and at least one lock mechanism. The locking device includes a first lock body and a second lock body detachable from the first lock body. The first lock body is connected with the first zipper slider, and the second lock body is connected with the second zipper slider. The locking element is arranged on the first lock body and is configured to lock with the second lock body. At least one lock mechanism is arranged on the first lock body or the second lock body to lock with the locking element.

A closure mechanism includes a first elongate closure member having a series of spaced features disposed along an entire length of the first elongate closure member. A second elongate closure member includes a series of spaced features disposed along an entire length of the second elongate closure member. The second elongate closure member sealingly engages the first elongate closure member. A slider interacts with (i) the series of spaced features on the first elongate closure member to produce a first feedback at a first frequency, and (ii) the series of spaced features on the second elongate closure member to produce a second feedback at a second frequency. The first feedback at the first frequency differs from the second feedback at the second frequency.

An ultra-thin plastic steel zipper includes: a pair of zipper fabric belts; two sets of teeth, respectively distributed along a direction of the pair of zipper fabric belts and engaged onto an inner side of each zipper fabric belt; a zipper head; a pair of top stops; and a bottom stop; the upper surface and the lower surface of the tooth are composed of three surfaces comprising a flat surface, a tapered surface, and a vertical surface, both an upper surface and a lower surface of the tooth has a tapered structure from the tooth head to the tooth tail, the overall volume of the teeth is significantly reduced, and the thickness and volume of the central line of the fabric belt are reduced, the established appearance of the plastic steel zipper is improved.

A zipper strap structure according to an embodiment includes a first strap, a second strap disposed side by side with the first strap, an internal coupling unit, and an external coupling unit. According to the invention, the internal and external coupling of the zipper strap structure is performed with very high accuracy and precision. In addition, when the zipper strap structure is operated, a user can intuitively recognize whether the zipper strap structure is opened or closed by senses of touch and hearing. Since a user can effectively seal contents by the internal and external coupling of the zipper strap structure and can clearly recognize an operation state of the zipper by senses of touch and hearing, the user does not have to perform repeated checking of whether or not a zipper is completely closed, unlike the related art.

Provided is a copper alloy fastener element which improves season cracking resistance by a means different from that of increasing a ratio of a 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 phase at a ratio of 10% or less.

The invention relates to a monitor device for monitoring the closed or open state of an article, the monitor device being in the form of an electronic circuit comprising a zip closure system comprising two strips, each having fastened thereto a row of elements, referred to as teeth (11, . . . , 14, 20, . . . , 25), which elements are made of electrically conductive material. A slider (3) is mounted to slide along the strips and is configured, in one direction, to cause the teeth of one row to mesh with the teeth of the other row, and in the other direction, to separate the teeth. A detector-and-signaling device (4) is connected firstly to at least one of the teeth, referred to as a first terminal (21), and secondly to at least one of the other teeth, referred to as a second terminal (24). The detector-and-signaling device is configured to detect the state of electrical continuity between the first and second terminals (21, 24), and to issue a signal as a function of said detected continuity state. The first terminal (21) and the second terminal (24) are spaced apart from each other by at least one tooth (22, 23), said at least one tooth having no electrical connection with said terminals when the teeth of the two rows are in the separated state.
