Zippers, including a device for replacing a malfunctioning zipper. In some examples, the zipper includes a plurality of attaching means that fit over the teeth of a malfunctioning zipper. In some further examples, the zipper may function to repair a tear in the material of an item.

An over the head gown is provided having a one-way lock for receiving a neck tie strap which facilitates closure of the head opening around the wearer's neck and closure of the rear gap in the back panels of the gown. Initially, the necktie strap is partially inserted through the lock, and then the gown is placed over the wearer's head. The loose end of the strap can then be pulled, without reaching behind the wearer's head or neck, to tighten the head opening and close the gap in the back of the gown. The gown can be removed by detaching the necktie strap or the lock from the gown then pulling the gown from the wearer's body.

A double open end zipper for both end positioning-based luggage includes first and second housing members respectively equipped with an N-shaped plastic strip at the rim thereof, and a double open end zipper including first and second zipper tapes respectively stitched to the N-shaped plastic strips at the first and second housing members in reversed directions with the box and pin of the first zipper tape respectively disposed adjacent to the pin and box of the second zipper tape subject to the guidance of a mark line at each N-shaped plastic strip, a seam allowance constraint block located at an outer rear side of the box of each of the first and second zipper tapes, two zipper sliders respectively coupled to first and second zipper tapes, allowing adjustment of the combined storage capacity defined in between the first and second housing members.

Fastener stringer includes a fastener tape provided with a fastener element; and a stop part arranged at an end of the fastener tape. The stop part includes: a magnetic body; an encapsulating member encapsulating the magnetic body; and an injection-molded portion that at least partially covers or surrounds the encapsulating member encapsulating the magnetic body. At least the encapsulating member hinders heat from being transferred to the magnetic body while the injection-molded portion is formed.
