Abstract: 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.

Guide rails are disposed along exterior sides of the complementary interlocking closure elements. A slider is disposed in straddling relation over the guide rails and an end-stomp is defined by a fused-together portion of the interlocking closure elements proximate an end of the closure mechanism. The end-stomp may include a flattened region, a first raised ridge that is generally parallel to the interlocking closure elements, and a second raised ridge that is generally perpendicular to the first raised ridge. The second raised ridge extends away from a pouch interior and beyond opening side lateral edges of the complementary interlocking closure elements a distance that is sufficient to engage a top wall of the slider.

Abstract: Embodiments provide a weather resistant slide fastener with a modified slider body including a top control rib and tightly controlled inner dimensions. In embodiments, a water-resistant coating and/or an adhesive may be applied to the zipper tape, resulting in a highly water-resistant zipper and finished garment. Embodiments further provide a slider body that may accommodate longitudinal edge portions of the outer layer of fabric, allowing the edges of the fabric to be brought into close proximity/contact, substantially covering the zipper teeth and minimizing ingress of water and/or wind through the zipper tape. Additional embodiments provide methods of manufacturing and installing weather resistant slide fasteners.

Abstract: The disclosure relates to a reclosable zipper for a package or bag wherein apertures are formed at periodic package-width intervals passing through the interlocking elements of the zipper profiles in order to minimize the mass of zipper material in areas where side seals of packages or bags will be subsequently formed. The otherwise interlocking elements upstream of, or at the trailing edge of, the apertures are deformed so as to prevent interlocking of the elements through a limited area. This allows a separator pin to pass through the area of the apertures and pass between the zipper profiles, eliminating or reducing the collision of the separator with the zipper profiles and subsequent potential damage to the zipper profiles.

In at least one embodiment, a lifting rib and closure bar on the slider cooperate with a lifting wing and closure bar groove on the upper and lower seal members, respectively. By moving the slider in one direction, the lifting rib lifts the upper seal member from the lower seal member. Moving the slider in the opposite direction causes the upper and lower seal members to interlock. In another embodiment, a slider has an intermediate lateral member connected on one side the slider top, and connected on the other side to the slider bottom.

Abstract: The present disclosure relates to a zipper for a reclosable package or bag and a method of forming thereof, wherein aligned apertures are cut into the zipper flanges proximate to the slider position when the package or bag is open. Portions of the front and rear walls of the package or bag extend through these apertures during the original manufacture of the bag, and are sealed to each other during the same sealing operation which seals the front and rear walls of the package or bag to the flanges of the zipper. The resulting seal between the front and rear walls, extending through the apertures in the zipper flanges, prevents the zipper profiles from opening in the portion where the slider is positioned when the reclosable package or bag is open.

Abstract: The use of coextruded or integral sealing ribs on zipper flanges enhances the quality of the sealing between the flanges and the walls of a reclosable package. The coextruded sealing ribs may be made from sealing resins or similar materials. Additionally, grip strips are placed on the opposite side of the flanges from the ribs in order to improve the quality of the sealing even further and to inhibit inner flange sealing.

The first and second handles (43, 45) can be released by moving right or left. A range of products can be provided which operate according to the same principles, but in which the first movement, for example left or right, varies between different products of the range.

Abstract: The end stop is formed on ends of a zipper for a reclosable package or bag by ultrasonically welding the ends of the zipper profiles together so as to form a raised portion. This prevents the slider from being pulled off of the ends of the zipper. Additionally, in the ultrasonic welding step, an indentation is formed into which glue is added thereby forming a lateral protrusion on the side of a zipper profile. This increases the strength of the end stop and increases the slider pull-off force which can be resisted.
