AI Technical Summary

Problems solved by technology

[0006] However, in the production process of the above-mentioned zipper teeth, it is necessary to apply the film first and then perform physical grinding, which leads to an increase in the process and increases the difficulty of production. The physical grinding is also prone to deviation, and the edge of the film after grinding is also easily damaged.

Embodiment 1

[0064] Such as image 3 As shown, the upper surface of the fastener element upper half 11 includes a first portion 111 and a second portion 112 in the width direction of the fastener tape 2 . The first part 111 is close to the head side of the zipper element 10 , and the second part 112 is close to the end side of the zipper element 10 . In the thickness direction of the fastener tape 2 , the second part 112 sinks relative to the first part 111 to form a stepped structure. Specifically, the sinking of the second part 112 relative to the first part 111 means that, in the thickness direction of the slide fastener 1 , the surface of the second part 112 is located between the connecting part of the first part 111 and the second part 112 and the second part 112. Below the connection line L formed by connecting the ends in the direction of the zipper element ends.

[0065] Such as Figure 10 As shown, although the first inclined portion 111b of the upper half of the zipper elemen...

Embodiment 2

[0071] Embodiment 2 of the present invention is different from Embodiment 1 in terms of the specific form of the second part 112 , and other structures are the same as Embodiment 1, and the description of the same structure is omitted here.

[0072] In Embodiment 1 of the present invention, the second portion 112 includes a first slope 112a that slopes upward with respect to the fastener tape 2 in the width direction of the fastener tape 2 as it moves away from the end of the fastener element, and a slope that is larger than the first slope 112a. The second slope 112b is inclined upward with a large slope. In contrast, in Embodiment 2 of the present invention, as Figure 4 As shown, the second portion 112 is a plane portion parallel to the fastener tape 2 (referred to as a second plane portion in the present invention).

[0073] Similar to Embodiment 1, according to the form of the second part 112 of this Embodiment 2, in the thickness direction of the slide fastener 1, the s...

Embodiment 3

[0076] Embodiment 3 of the present invention is different from Embodiment 1 in terms of the specific form of the first part 111 , and other structures are the same as Embodiment 1, and descriptions of the same structures are omitted here.

[0077] In Embodiment 1 of the present invention, the first portion 111 includes a first planar portion 111a parallel to the fastener tape 2 and a first slope portion 111b inclined downward relative to the fastener tape in the width direction of the fastener tape 2 . The first planar portion 111 a is adjacent to the second portion 112 . In contrast, in Embodiment 3 of the present invention, as Figure 5 As shown, the first portion 111 is parallel to the plane of the fastener tape 2 .

[0078] Since the form of the second part 112 in the third embodiment is the same as that in the first embodiment, the same effects as those in the first embodiment can be obtained also in this third embodiment.

Abstract

The present invention provides a slide fastener having a fastener tape and a plurality of scoops provided on one edge of the fastener tape in the width direction, the edge of the fastener tape being provided with a core, the scoops having scoop upper half parts disposed on a first surface side of the fastener tape and scoop lower half parts disposed on a second surface side of the fastener tape, a storage part matched with the core part is formed between the scoop upper half parts and the scoop lower half parts, the slide fastener is characterized in that the upper surfaces of the scoop upper half parts comprise first parts and second parts in the width direction of the zipper tape, the first parts are located on the side close to the head parts of the scoops, the second parts are located on one side close to the tail ends of the scoops, the second parts sink relative to the first parts to form step parts in the thickness direction of the zipper tape, and pasting films are arranged on the first parts while no pasting films are arranged on the second parts.

Description

technical field [0001] The present invention relates to a zipper in which a plurality of zipper elements made of resin are arranged by injection molding on the opposite tape side edges of a pair of left and right zipper tapes. Zipper with variable metallic luster. Background technique [0002] Conventionally, as fastener elements used in slide fasteners, there are known resin fastener elements formed individually by injection molding resin on a fastener tape, and resin fastener elements formed by forming a monofilament into a coil shape or a zigzag shape. Continuous fastener elements (called nylon zipper in the industry), metal fastener elements formed by fastening substantially Y-shaped metal fastener element blanks to fastener tapes, and the like. Among them, resin zipper teeth have relatively simple manufacturing process, and only need to make relevant molds to produce various resin zippers with different shapes. Therefore, the shape of resin zippers is the most variable...
