Fast snapping zipper and its elements

Abstract

The invention discloses zipper teeth of a novel firmly-meshed zipper. Each zipper tooth comprises a tooth head, a tooth neck and a tooth tail, wherein the tooth head, the tooth neck and the tooth tail are sequentially connected. For each tooth, the tooth head is provided with an outer tooth head and an inner tooth head, the tooth neck is provided with an outer tooth neck and an inner tooth neck, the tooth tail is provided with an outer tooth tail and an inner tooth tail, the outer tooth head, the outer tooth neck and the outer tooth tail form an outer tooth, the inner tooth head, the inner tooth neck and the inner tooth tail form an inner tooth, and the outer tooth head is diminished from inside to outside. The invention further discloses the zipper with the zipper teeth. According to the zipper teeth and the zipper with the zipper teeth, due to the fact that each outer tooth neck is diminished from inside to outside, a recession space can be formed when the zipper is closed and bends outwards, the outer teeth will not be abutted, disturbing force making the meshed zipper teeth disengage can be prevented, and therefore meshing stability of the zipper in an outward-bending state can be improved. Due to the fact that each outer tooth neck is diminished from inside to outside, the closed zipper can bend outwards more easily, the radius of the bending portion is small, and the closed zipper can be smoother, more fitted and suitable for high-grade products like high-grade clothes.

Description

technical field [0001] The invention relates to a zipper with stable bite and its chain teeth. Background technique [0002] Existing slide fasteners mainly include a cloth tape and chain teeth arranged on the cloth tape. For the convenience of description, when the zipper is sewn on objects such as bags and clothes, the outside of the zipper is pointed to the outside of the bag and clothes after the zipper is closed, and the inside is pointed to the inside of the bags and clothes. [0003] Wherein, chain teeth include tooth heads, tooth necks and tooth tails connected together in sequence, and if viewed from inside and outside directions, chain teeth include outer teeth and inner teeth that are relatively joined together. [0004] When the zipper is closed, the two rows of chain teeth are relatively staggered and bit together. When the zipper is pulled and bent outwards, the staggered outer teeth will push against each other, which will cause disengagement interference to...

AI Technical Summary

Problems solved by technology

When the zipper is pulled and bent outwards, the staggered outer teeth will push against each other, which will cause disengagement interference to the occluded outer teeth, and it is easy to make the chain teeth disengage. poor

Similarly, when the zipper is bent and closed inward, the internal teeth are against each other, which will cause disengagement interference to the internal teeth that are engaged together, and it is also easy to cause the teeth to be separated from the bite, and the bite stability is relatively high.
