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 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.

A zipper assembly for a reclosable enclosure includes a first profile having a first elongated supporting element and first protruding intermeshing elements. The zipper assembly also may include a second profile having a second elongated supporting element and one or more second intermeshing elements protruding from the second elongated supporting element. The one or more first intermeshing elements may releasably interlock with the one or more second intermeshing elements to close the enclosure. Each of the first elongated supporting element and the second elongated supporting element may include a thicker portion and a thinner portion. The thicker portions of the first elongated supporting element and the second elongated supporting element may be coupled with one or more panels of the enclosure. The thicker portions of the first elongated supporting element and the second elongated supporting element may be disposed on a consumer side of the enclosure.

A buckle may include male and female parts. In a case (A) where only the female part is attached to a slider of a slide fastener, the male part includes: a pair of arms respectively provided with locking protrusions; and a connecting rod connecting respective base ends of the pair of arms. The connecting rod is configured to curve away from a space between the locking protrusions of the arms when the arms are bent such that the locking protrusions approach one another. In a case (B) where the male part is attached to a slider of a slide fastener, the male part includes: a slider-holding frame configured to hold the slider; and a pair of arms that extend in the same direction from the slider-holding frame and are respectively provided with locking protrusions. The slider-holding frame includes a frame portion protruded into a space between the pair of arms toward a space between the locking protrusions.

A slider for a zipper closure includes a separator plow that is positionable between interlocking tracks of the zipper closure to open the zipper closure by pivoting an opening end of the slider in a direction toward a notch to position the plow between the interlocking closures. The slider can be disengaged by pivoting the slider so that the plow is outside of the interlocking tracks.

A slider for a waterproof slide fastener includes an upper blade and a lower blade opposing each other in an up-down direction, and a connecting post connecting the upper blade with the lower blade. Each of opposing surfaces includes a close-contact surface for sandwiching and close-contacting with a first stop in the up-down direction. At least one of the opposing surfaces includes right and left inclined surfaces provided respectively on right and left sides at a front sides of the close-contact surface and inclined in a direction widening a gap between the upper blade and the lower blade as the right and left inclined surfaces go forward. The at least one of the opposing surfaces includes an extended close-contact surface provided between the right and left inclined surfaces and extending forward from the close-contact surface.
