There is provided a slider for a slide fastener. A slider body includes an upper blade disposed at a front side of the slider body, which is a pull-tab attachment side, a lower blade disposed at a back side of the slider body, which is opposite to the front side, and a connecting post connecting the upper blade and the lower blade to each other. A fibrous fabric sheet is integrally fixed to a back surface of the lower blade at the back side, with an adhesive layer being interposed between the fibrous fabric sheet and the back surface of the lower blade.

In a slide fastener, a fastener tape is woven with a single-woven structure, and in the fastener tape, a double-woven region woven with a double-woven structure is formed along a tape longitudinal direction. An inner single-woven region and an outer single-woven region of the single-woven structure are formed at a tape inner edge side and a tape outer edge side of the double-woven region. Thus, even if the fastener tape makes contact with ridge line portions on a lower blade side of the slider when the slider is slid, weft yarns arranged in the double-woven region are less likely to be cut.

A conventional zipper is the preferred means for closure of many jackets and other outerwear. Conventional zippers are prone to jamming and snagging due to the introduction of the liner into the slider body as the zipper is opened and closed. Embodiments herein provide modified slider bodies with one or more features such as an elongated spring cap, a protrusion on the bottom plate and/or plate coupler of the slider body, and/or vertically offset side rails. These features may minimize introduction of loose fabric, such as the lining of a lined garment, into the tape slot of the slider body, thereby help reduce jamming of the slider body during operation of the slide fastener.

A slider includes a lower blade, an upper blade, a guide pillar, and a pair of flanges. The flanges are respectively disposed on lateral edges of one of the lower blade and the upper blade, and the inner surface of another one of the lower blade and the upper blade and the end surface of the flanges are opposite to each other and separated by a gap. A first groove is provided on a side surface of the guide pillar and corresponds to the gap. A fastener includes a pair of fastener stringers and the slider. The fastener stringers include a fastener tape and an element column coil. A boundary between the first groove and the side surface of the guide pillar forms a step portion, and the step portion is located between the fastener tape and the element column coil.

A slider for a slide fastener includes: a metal slider body which includes an upper blade, a lower blade, and a connecting column connecting the upper blade and the lower blade at front sides thereof, a stringer passage which allows facing side edge portions of a pair of fastener stringers to pass therethrough being formed on an inner side of the slider body; and a component which is accommodated in the slider body. The slider body includes a recess which is recessed on a surface of the slider body and in which the component is accommodated, and a dedicated vent hole which allows ventilation between an outside of the slider body including the stringer passage, which is outside the slider body, and an inside of the recess.

An anti-jamming zipper apparatus, and systems and methods for using the same, are provided. The apparatus can include a first portion having a first front and back wall and is adjacent to a second portion having a second front and back wall. The front and back walls can be concave and angled away from a central axis of the first and second portion and can facilitate a more effective means of restoring the zipper when debris and clothing material obstructs its range of motion. The apparatus can include a tape separator connected to the first and second portions, a track, and two track branches. A front point can extend from the front walls and a back point can extend from the back walls. The apparatus can include a divider connected to the first portion and a ramp connected between the divider and front point. The apparatus can also include at least one protrusion on at least one wall.

Pants housing a catheter that drains to a collection bag, said pants having a left and a right panel, wherein each panel is a covering element has a continuous zipper tape that is coextensive with the fabric forming a pant, wherein the panels provide a selectable portlets to the collection bag mounted on a wearer's anterior thigh to activate drainage or to service a connection of the catheter to the collection bag, and a selectable port to inspect, tighten straps and/or replace the collection bag. It is anticipated that the wearer may be in a wheelchair when these actions are performed.

Fastener stringer includes: a fastener tape; a fastener element arranged on a side edge portion of the fastener tape; and a covering member made of soft material and covering the fastener tape, the covering member comprising a sealing portion positioned on an opposite side of the fastener element with respect to the fastener tape in a thickness direction of the fastener tape. The covering member includes a flexible core sheet extending in a longitudinal direction of the fastener stringer. The core sheet is embedded in the soft material such that one surface of the core sheet is at least partially exposed or both surfaces of the core sheet are not exposed.

A method can include obtaining a zipper assembly having front and rear flanges with interlocking elements that mate with and disengage from each other to provide a resealable opening into a bag assembly. The front flange can include a tear strip configured to be pulled away from the front flange to tear through at least one panel of the bag assembly and provide access to the interlocking elements and the resealable opening. The method also can include punching a hole through the front flange around the tear strip with a hole punch. The hole removing a first portion of the front flange and leaving a second portion of the front flange. The second portion of the front flange forming a pull tab connected to the tear strip and configured to be pulled to separate the tear strip from the front flange.
