Detailed Description

The utility model is further described below with reference to the accompanying drawings.

The first embodiment is as follows:

as shown in fig. 1 to 6, a novel fastener element comprises a fastener element body 1, the fastener element body has an upper element body 11 and a lower element body 12, the upper element body 11 is provided with at least one protrusion 110, and the protrusions 110 between two mutually engaged fastener element bodies 1 form an engaged protrusion structure. The design of the bulge 110 in the utility model not only enables the surface of a single zipper tooth to be rich in stereoscopic impression and layering sense, but also enables two zipper teeth which are mutually meshed to be more indicative and interesting, and is beneficial to improving the novelty and the attractiveness of the integral shape of the zipper.

As shown in fig. 1 to 6, in a production application, the shape of the protrusion 110 can be designed reasonably according to actual needs, for example, it can be designed as a strip shape, a wave shape or other geometric shapes, etc., but it should be noted that the protrusions 110 on two elements 1 engaged with each other should be engaged with each other to form a complete protrusion structure. Preferably, the protrusion 110 in this embodiment is shaped like a bar, and the included angle α between the protrusion 110 and the center line of the element body 1 is 25-35 °, so that the protrusion structure between two element bodies 1 engaged with each other can form an oblique straight line which is directly connected with each other.

As shown in fig. 1 to 6, the side wall of the middle part of the lower dental body 12 is provided with an engaging groove 121; the width of the middle portion of the upper dental body 11 is larger than the width of the middle portion of the lower dental body 12, and a shielding portion 111 for shielding the engaging groove 121 is formed. After two chain teeth intermeshing about, shielding part 111 can play spacing effect on the one hand, stagger from top to bottom after preventing the chain tooth amalgamation, and on the other hand can effectively shelter from meshing groove 121 to help further promoting the whole pleasing to the eye degree of zip fastener.

As shown in fig. 1 to 6, in order to further enhance the stereoscopic impression of the zipper and save the production cost sufficiently, the upper element 11 is provided with a missing block 112 at the tooth head, so that the tooth head of the lower element 12 forms an exposed cross section 122.

As shown in fig. 1 to 6, in order to achieve the above-mentioned effects, the upper element body 11 of the element body 1 is rectangular, and the protrusion 110 is disposed at a diagonal position of the upper element body 11. Preferably, the number of the protrusions 110 is 1. During production, concave triangular concave parts can be dug at two opposite corners of the upper tooth body 11, so that a linear strip-shaped bulge is formed in the middle of the upper tooth body 11, the material consumption of the zipper teeth can be reduced, and the production cost is saved. In order to ensure the stereoscopic impression and the overall texture of the fastener element, the height of the protrusion 110 should be controlled to be 0.4-0.7 mm.
