A cover attachment structure includes a sheet-shaped cover member, a base, and a fastener member. The fastener member includes a first element row and a second element row. The base has a recessed groove extending along a surface thereof. Fastener elements of the first element row and the second element row are received in the recessed groove and locked in the recessed groove in a state in which engaging head portions of the fastener elements engage with each other. The recessed groove is configured such that a minimum groove width thereof in a width direction orthogonal to a length direction of the recessed groove is less than 2 times a length, in the width direction, of either one of the fastener elements received in the recessed groove.

Various implementations include a slide fastener that has a blocking element on one stringer that prevents engagement compatibility with standard elements on the other stringer. For example, at least one blocking element is coupled to a first stringer, and first and second blocking coupling elements are coupled to a second stringer. The contour of the blocking element and the contour of the blocking coupling elements are different from the contour of the standard elements on the stringers such that the standard elements do not engage with the blocking element or the blocking coupling elements in an alternating arrangement. However, the contour of the blocking element and contour of the blocking coupling elements allow for the engagement of the blocking element with the blocking coupling elements in an alternating arrangement.

A method of installing a slide fastener assembly in a thin shell garment includes: providing a slide fastener chain comprised of two interlocked rows of teeth, each row of teeth being attached to a cord bundle of a respective slide fastener tape; removing the interlocked rows of teeth from a portion of the slide fastener chain, thereby defining a length of the slide fastener chain without teeth; introducing a reinforcing film to the cord bundles, at a location along the length of the slide fastener chain without teeth, to shape the cord bundles for accommodation of a pin and box assembly; cutting the slide fastener chain at a film-reinforced location along the length of the slide fastener chain without teeth, thereby defining a semi-finished slide fastener assembly terminating in a film-reinforced end; and attaching the semi-finished slide fastener assembly to one or more panels of a thin shell garment. After attachment of the semi-finished slide fastener assembly to the one or more panels of the thin shell garment, the pin and box assembly is installed at the film-reinforced end of the semi-finished slide fastener assembly.

Provided is a slide fastener-attached product in which an element member, is fixed to an element attaching edge portion of a fastener attached member with a sewn portion for fixing. The sewn portion for fixing pierces the element attaching edge portion, and a thread forming the sewn portion for fixing holds a connecting member. A position that the sewn portion for fixing pierces the element attaching edge portion is apart from an element to be inside of the element attaching edge portion. Thereby, weight reduction and improvement in flexibility of the slide fastener-attached product can be achieved.

A magnetic zipper includes a pair of mating strands each having a plurality of spaced teeth formed on an inner edge thereof with mating notches formed therebetween. Positioned within each of the notches on both strands is a magnet having a given polarity. Attached to each tooth on both strands is a magnet having a polarity opposite that of the given polarity. The size or geometric configuration of the teeth and notches successively vary so that the two strands cannot be inadvertently joined when misaligned. Accordingly, when the teeth on one strand are positioned near or in their designated notches on the other, the zipper strands firmly adhere to close a garment opening. To open the zipper, a garment wearer simply pulls the tenuously-held zipper strands apart.

A multi airtight type rail zipper may be attached to or installed on a flexible material, such as an envelope, for storing an object. The multi airtight type rail zipper includes a first zipper rail, a second zipper rail formed in a shape corresponding to that of the first zipper rail, and a slider provided to surround the first zipper rail and the second zipper rail such that, according to the direction of sliding movement, the first zipper rail and the second zipper rail engage with and are fastened to each other, or disengage and are unfastened from each other. The multi airtight type rail zipper can improve the sealing force by the more stable fastening structure.
