Description

{Closed-end zipper with finished bottom stopper}

The present invention relates to a zipper. More particularly, it relates to a locked zipper having a bottom stopper.

The zipper is a pair of zipper tapes (tape) with a set of teeth formed along the edges on both sides of the slider, so that the teeth of the pair of zipper tapes can be combined or separated according to the reciprocating motion of the slider. It is a fastener. Such a zipper may be referred to as a zip, a chirk, a fastener or a slide fastener, and is used for various purposes in various clothing and fashion accessories.

Specifically, the zipper may be divided into a closed-end zipper, an open-end zipper, and a two-way separator zipper according to its function. Among them, the locked zipper is a zipper in which one or both ends of the two zipper tapes are joined while the pair of zipper tapes are completely opened by the slider. An open zipper is a zipper in which a pair of tapes are separated from each other while a pair of zipper tapes are completely opened by a slider. The two-way zipper is a zipper with two sliders that can open and close a pair of zipper tapes in both directions. Such a two-way zipper may be further classified into a two-way zipper in which two sliders are arranged in head to head, and a two-way zipper in which two sliders are arranged in bottom to bottom.

1 is a front view of a conventional locked zipper.

As shown in FIG. 1, the conventional conventional locked zipper is provided with the teeth of the zippers 20 facing each other at the inner ends of the two zipper tapes 10 facing each other. At the bottom of the locked zipper, two zipper tapes (10) are joined, and a bottom stopper (30) is installed to prevent the slider 50 from proceeding further, and a slider (50) is provided at the top of each zipper tape (10). An upper stopper 40 is provided so as not to deviate from each zipper tape 10. Then, between the two zipper tapes 10 of the locked zipper, a slider 50 for coupling or separating the respective teeth is installed.

On the other hand, the conventional method of manufacturing a locked zipper can be divided into a method of manufacturing using an automated machine and a method of manually manufacturing by a person. However, when the locked zipper is manufactured using an automated machine, there is a problem in that defective products such as the dentition 20 of the zipper are opened, or the lower limb 30 or the upper limb 40 is not installed in the correct position. Therefore, when a high-quality locked zipper is required, it is still manufactured by human hand to maintain a uniform quality.

Figure 2 is an exemplary view showing a method of installing the lower leg of the conventional locked zipper. And, Figure 3 is an enlarged view of the lower extremity and teeth installed in a conventional locked zipper.

As shown in FIG. 2, the metal base 30 not yet installed between the two zipper tapes 10 has a shape similar to the letter X. That is, the lower limb 30, which has not yet been installed, has vertical wings in the left and right directions.

The metal base 20 of the conventional locked zipper inserts the zipper tape 10 between the upper and lower wings in the left and right directions of the base 30, and then presses (P) the metal base 30 in the up and down direction (P) to make the base 30 ) The upper and lower wings of the) are bent in the direction of the zipper tape 10, and the zipper tape 10 is fixed between the upper and lower wings to be installed.

However, when the metal base 30 is installed in such a way that it is pressurized (P) in the vertical direction, the surface of the installed base 30 is not flat, and the trace M of the upper and lower wings of the base 30 is bent. do. In addition, when the surface of the base 30 is plated or painted, the plated or painted surface of the base 30 is peeled off during the pressure installation process.

On the other hand, the teeth dentition 20 installed on each of the two zipper tapes 10 are arranged to be crossed with each other so as to be engaged with each other or to be opened separately. Therefore, only the distal tooth 20-1 installed on one of the two zipper tapes 10 is contacted with the lower leg 30, and the other end of the zipper tape 10-2 is distal. A constant empty space B is formed between the teeth 20-2 and the lower limb 30.

As described above, since the empty space B formed between the distal tooth 20-2 and the lower limb 30 has a size corresponding to half the width of the tooth, it is applicable when a relatively large (lake) tooth is used. The size of the empty space B also becomes relatively large. And, the empty space (B) formed between the distal tooth (20-2) and the lower leg 30 exposes the object inside the zipper to the outside.

In summary, conventional conventional locked zippers leave a bent trace (M) on the surface of the base 30 installed under pressure, or the plating or paint is peeled off during the pressure installation process, and the distal teeth 20-2 and the base 30 ) Through the empty space (B) formed therebetween has a problem that the object inside is exposed to the outside.

Therefore, when a conventional locked zipper is installed in an expensive luxury bag or the like, there is a fear that the product value or brand value is lowered.
