revised form of a zip lock

locking tab includes a zipper teeth and an attractive cloth tape. Fabric tape includes a portion sewing joined the teeth of participation on the lateral side of the engaging teeth, and stretch fabrics of yarn located away from the seam that allows fabric tape that stretches to form a curve.

The zipper is a locking device commonly used in daily so it can be easily seen ready-made garments, hand bags, sleeping bags, tents. . . And so on. The zipper provides advantages such as being properly operated and be durable, and these are the reason why it is so commonly used and replaces many traditional locking device.

Above all, there are three types closures available based on the same material and are, respectively, metal zippers, nylon and fiber reinforced plastics. Usually, a zipper is composed a lock and a Slier tab and locking tab provides two opposing lines of teeth to engage with others and a band of material extends laterally from coupling teeth attached to an article by sewing. The teeth of the participation in a metal zipper and a zipper reinforced plastic fiber are removed independently and neighboring teeth are equally spaced so that two lines in front of the teeth can relate to others. As for nylon zipper, the teeth of the heat are nylon or polyester filament and is curved to form continuous spirals or coils to be able to relate with others the opposite. Therefore, the manufacture of the locking tab on the zipper is nylon after the spirals or coils are formed before the tape fabric can be sewn into an article.

Although the conventional closure can interlock two parts of an article, a small imperfection the rack is limited to being a form of straight line. Ie, it is difficult to form a curve shape of the zipper, while the sewing work is performed, especially for the metal rack and the rack of fiber reinforced plastic. The engaging teeth on the metal rack and the rack of fiber reinforced plastic were chosen in such a way that is very limited for the permanent teeth to be doubled. As participation in the teeth of the zipper nylon, although the form of continuous rolls and flexion of the material that can bend coupling teeth properly, a fixed length of fabric tape makes the sewing work can not be done easily.

The previous bottleneck in relation to the rack in use or restricted work is product design to prevent the union of the curve and the line work Straight only. However, the shape of the curve is inevitable for product design or manufacture of clothes made for how to get a card that is intertwined formed in the shape of the curve is a value subject to develop in order to solve the problem of the conventional zipper.

An object of this invention is to provide a revised form of a zip lock, with which it can be a form of the curve of the zipper is working out in addition to the straight-line due to a band of material of the elastic property providing teeth and its involvement may be lengthened.

Therefore, it is appreciated that the present invention causes the locking tab can be worked with a curved shape and get into shape, and extends the scope of the zipper and zipper deign provide a form of the curve as desired. Moreover, the present invention can improve product quality and accuracy of the profiles.
