Abstract: This invention relates generally to fasteners, and more particularly to slide fasteners, commonly known as zippers, and a method of forming the same, which may be used to fasten three or more sets of links together, as well as, to provide a collapsible, rigid support for loads which may be applied axially and laterally to the fastened together links. The invention is easily stored and uses a single slider for interlocking the separate sets of elements in a simple and effective manner. The tapes have multiple links secured thereto and extend orthogonally therefrom. The slider has guideways through which the links may pass. The tapes and the links are passed downward through the slider element to thereby intersperse and interlock the links and thus the tape. The opposite movement through the slider causes the links to be separated and disjoined.

The other ends of the second and third tapes are kept free. The first and second tapes are fastened together by moving the first slider toward the second slider, whereas the first and third tapes are fastened together by moving the second slider toward the first slider.A bag-shaped article with the three-tape type zipper secured thereto is also disclosed which comprises a body with an opening formed thereon through which things are inserted.

Abstract: A slide fastener chain comprises a pair of inter-engaged stringers including a pair of stringer tapes one longer than the other which have longitudinally staggered ends spaced from each other by a distance greater than the length of a slider which is to be mounted on the slide fastener chain. The coupling heads of a predetermined number of coupling elements on the longer stringer tape adjacent to the end of the shorter stringer tape and remote from the end of the longer stringer tape are cut off so that the coupling elements thus severed are kept uncoupled from opposite companion coupling elements on the shorter stringer tape. The slide fastener chain thus constructed can smoothly be threaded through the slider.
