摘要： A water-tight and gas-tight zip fastener with a sealing port and a method for forming the same provides a zip fastener made of plastic in which preferably spirals in a spiral zip fastener are injection molded with a thermoplastic elastomer which forms a continuously contoured coating, bearing directly on the contiguous edges of the zip fastener strips, and when the zip fastener is closed, the coatings are under compression and form a contiguous seal with each other and to the zip fastener slide to prevent undesirable gas and water penetration.

摘要： A zipper guide for use in a slider insertion machine in which the zipper guide can be easily loaded with zipper tape without disassembly of the zipper guide. The slider insertion apparatus comprises: an assembly for inserting sliders onto a zipper tape; first and second shafts that are fixed relative to the assembly; a zipper guide for guiding the zipper tape during longitudinal movement of the zipper tape and supporting the zipper tape during slider insertion; and a retainer coupled to the first shaft and movable between first and second retainer positions. The zipper guide comprises a stationary part that is fixed relative to the assembly and comprises a first groove, and a rotatable part that is rotatable about the second shaft between first and second angular positions and comprises a second groove. The retainer is coupled to the rotatable part in the first retainer position to block rotation of the rotatable part and is uncoupled from the rotating part in the second retainer position to not block rotation of the rotatable part.
