A plastic product disposed on a strap is provided. The strap is a soft string type textile. The plastic product includes a first injection molding portion and a second injection molding portion. The second injection molding portion is combined with the first injection molding portion to form the plastic product. An end portion of the strap protrudes out of the first injection molding portion and is completely covered by the second injection molding portion. A length of the first injection molding portion along a longitudinal direction of the strap is less than a length of the plastic product along the longitudinal direction of the strap. A protruding length of the end portion of the strap protruding out of the first injection molding portion along the longitudinal direction of the strap is less than half of a thickness of the second injection molding portion along a radial direction of the strap.

A slider for a closure assembly of a bag. The slider has a pair of finger pads extending from a top wall. Each pad has a surface with a curved portion running from a front end to a back end of the slider, a defined, first curved area extending from the curved portion to an end of the first curved area, and a defined, second curved area extending from the end of the first curved area to a midpoint of the curved portion. The first curved area and the second curved area are defined by different angles at which the respective curved area extends into the respective finger pad. Each finger pad includes a major axis dimension greater than a minor axis dimension to provide an area that fits an average finger size, and a lip region to guide a finger of a user into a finger pad.

A zipper includes zipper teeth, a zipper head base for engaging or disengaging zipper teeth, and a puller with an end hole. The zipper head base includes a body with a pivotal mounting portion, a hook-shaped locking plate with a locking pin, and a biasing member, the hook-shaped locking plate is pivotally connected to the pivotal mounting portion, and the locking pin of the hook-shaped locking plate is configured to pass through the end hole of the puller. The zipper head base has a locked state, in which the biasing member provides a biasing force to the locking plate, so that the locking pin is allowed to be inserted into the engaged zipper teeth to restrict bidirectional movement of the zipper head base. A garment including the zipper is further provided according to the application.

The adjustable zipper pull assembly includes a cord having a plurality of protrusions extending from the cord. A slidable member is disposed on the cord and is slidable relative to the cord. The slidable member includes a first aperture that receives a first region of the cord, and a second aperture that receives a second region of the cord such that the cord defines a closed loop. The slidable member and the protrusions are flexible relative to one another in order to enable the slidable member to slide over the protrusions while sliding relative to the cord, which adjusts a size of the closed loop about a top portion of a zipper slider. The adjustable zipper slider assembly may be used to avoid replacing a damaged zipper slider.

The present disclosure discloses a zipper comprising two zipper tapes and a zipper puller. The two zipper tapes are fastened or separated at the same time via the zipper puller; each zipper tape includes a fixing seat, a side barrier strip and a barbed strip, wherein the side barrier strip and the barbed strip are integrally formed on one side of the fixing seat, a slot is formed between the side barrier strip and the barbed strip, the barbed strip on one set of zipper tape fits into the slot on the other set of zipper tape, the end of the barbed strip away from the fixing seat is provided with barbs, the slot is provided with barb grooves, and the barbs on one set of zipper tape fit into the barb grooves on the other set of zipper tape. The present disclosure further reduces the production cost of zippers.

A fastening system for a zipper is disclosed which includes locking or interlocking first and second zipper pull tabs. A first zipper pull tab comprises a first base, a hook extending from the first base, and a movable gate coupled to the first base. A second zipper pull tab comprises a second base, a cover coupled to the second base, and a post extending between the second base and the cover. For interlocking, the movable gate and hook are further coupled around the post to provide the interlocking configuration of the first and second zipper pull tabs. The first zipper pull tab may be utilized separately from the second zipper pull tab, such as to lock to a coupling ring or another component of a carrying bag.

A slider for slide fasteners may include a slider body and a closure part. The closure part may include a closure portion for closing the gap between a free end portion of a pull tab attachment post and an upper blade; an upper engaging portion provided above the closure portion and engageable with the free end portion of the pull tab attachment post and a leg portion provided below the closure portion. The leg portion may include a rod portion extending from the closure portion along the coupling post and a lower engaging portion coupled to the rod portion and engageable with a lower blade.

There is provided a slider assembly for a slide fastener, including: a slider body; a pull-tab; and a resilient locking member. The pull-tab is provided with a window aligned with an aperture in an upper wing of the slider body when the pull-tab is in a first angular end position. A distal end of the locking member extends towards a guide channel through the window and the aperture. The locking member is configured to be resiliently biased towards a locking position where a distal end thereof protrudes in the guide channel. A proximal end of the pull-tab has a cam cooperating with the locking member such that the locking member takes the locking position when the pull-tab is in the first angular end position, and the locking member is moved towards an unlocking position when the pull-tab is pivoted away from the first angular end position.

There is provided a slide cover for a slide fastener. A pair of second guide element passages are formed in a space among an upper plate, a lower plate, a pair of outer wall portions and a pair of inner wall portions to guide a pair of separated element rows into a first element guide passage of a slider. The upper plate, the lower plate and a connection post have a concave surface, which is recessed in a disengaging direction of the slider, in a surface facing toward an engaging direction of the slider. The pair of second guide element passages are configured so that tip ends of the pair of inner wall portions in the engaging direction are located at the same positions as or at a side of the engaging direction relative to tip ends of the pair of outer wall portions in the engaging direction.
