A zipper head assembly structure includes a sliding member and a pull member. The sliding member includes a sliding element, an elastic member, and a locking hook, the sliding element has a base portion, a first lateral wall portion, a second lateral wall portion, and a seat portion, and an inner surface of the seat portion is configured with at least one retaining block. The first lateral wall portion and the second lateral wall portion respectively extend upward from opposite side ends of the base portion, mutually corresponding to each other, and are connected to a front end of the base portion. The seat portion is disposed on the base portion and connected to a rear end of the base portion.

A slider is provided with a tab insertion gap between an upper blade of a slider body and a free end portion of a cover body and an open and close member for opening and closing the tab insertion gap. The open and close member is disposed alongside a stop pawl body in the slider width direction, and is also disposed such that a rear end part of the open and close member can swing vertically between a passing position where a attaching shaft portion of a tab passes through and a blocking position where the passing of the attaching shaft portion of the tab is blocked. The open and close member is urged toward the blocking position. The slider can attach the tab afterward, has a stop mechanism, and can significantly reduce manufacturing costs.

A method of manufacturing a cap structure includes providing an initial cap body; placing an elastic piece on an inner surface of the initial cap body; and then punching the initial cap body to form a cap body. The cap structure includes a cap body and an elastic piece. The cap body has at least two first inner concave grooves, at least two first retaining blocks and at least two first through holes. The at least two first inner concave grooves are disposed on the inner surface of the cap body, and the at least two first through holes pass through the cap body. The elastic piece is disposed on the inner surface of the cap body, and the at least two first retaining blocks contact the elastic piece for retaining or abutting the elastic piece.

A zipper head assembly structure including a zipper head element and a puller is provided. The zipper head includes a zipper head body, a cap body disposed on the zipper head body, and a hook disposed inside the cap body. The cap body includes two curved surfaces opposite to each other. The hook includes a holding part, a hooking part, and a connecting element connecting the holding part and the hooking part. The connecting element includes a protruding block near the holding part. The puller includes a through opening hooked by the locking hook member. The width of the through opening is smaller than the distance between the protruding block and the adjacent curved surface.

A slider with a reboundable pull-tab includes a slider base, a pull-tab, a connecting shaft and spring; the slider base has a connecting shaft through-hole for mounting the connecting shaft, which fixes the pull-tab and spring onto the slider base; one end of the spring inserts into the slider, and the other end inserts into the spring base; when the pull-tab is pulled, the spring will subject to torsional deformation; when the pull-tab is let go, the pull-tab will revert to the normal state under the impetus of the spring, then the slider is automatically locked, thus preventing unexpectedly sliding; there is also a locking part in the pull-tab, so that it is free from not being able to rebound due to over-rotation.

A slider for a slide fastener includes a body, a pull-tab, a control claw, and a cover. The control claw is placed on a shaft portion between a front attachment column and a rear attachment column. A protrusion length of a claw portion that enters an element path from a claw hole changes depending on an up-down position of the shaft portion so as to control movement of the body. The cover is attached to the front attachment column and the rear attachment column so as to be swingable in an up-down direction. The upper plate portion pushes the control claw downward due to a restoring force of a plate spring portion extending from a front end of the upper plate portion along a front surface of the front attachment column. The body, the pull-tab, the control claw, and the cover are separate components.

A zipper slider assembly structure and a connecting ring are provided. The zipper slider assembly structure includes a sliding assembly, a connecting ring, and a pull element. The sliding assembly includes a sliding element having a through hole, an elastic element disposed on the sliding element, and a movable fixing element movably disposed on the sliding element. The elastic element is elastically abutted against the movable fixing element. An end of the movable fixing element has a limiting part passing through the through hole. The connecting ring movably cooperates with the movable fixing element. The pull element movably cooperates with the connecting ring. The connecting ring has an outer arc surface contacting the sliding assembly and the pull element by point-contact to decrease a contact area between the connecting ring and the sliding assembly and between the connecting ring and the pull element.

A zipper head assembly structure including a zipper head element and a puller is provided. The zipper head includes a zipper head body, a cap body disposed on the zipper head body, and a hook disposed inside the cap body. The cap body includes two curved surfaces opposite to each other. The hook includes a holding part, a hooking part, and a connecting element connecting the holding part and the hooking part. The connecting element includes a protruding block near the holding part. The puller includes a through opening hooked by the locking hook member. The width of the through opening is smaller than the distance between the protruding block and the adjacent curved surface.

A slider is provided with a tab insertion gap between an upper blade of a slider body and a free end portion of a cover body and an open and close member for opening and closing the tab insertion gap. The open and close member is disposed alongside a stop pawl body in the slider width direction, and is also disposed such that a rear end part of the open and close member can swing vertically between a passing position where a attaching shaft portion of a tab passes through and a blocking position where the passing of the attaching shaft portion of the tab is blocked. The open and close member is urged toward the blocking position. The slider can attach the tab afterward, has a stop mechanism, and can significantly reduce manufacturing costs.
