AI Technical Summary
When traditional bag zippers are sewn onto the bag body, the seams are exposed on the zipper strip, requiring additional processes such as adding plastic strips to cover the seams and binding the edges, which increases production costs and does not yield good results.
Design a composite zipper for bags, featuring a guard strip to cover the seams and a covering strip to replace the edge binding, both integrally formed with the strip, simplifying the manufacturing process and directly covering the seams and edge binding.
Simplify manufacturing processes, reduce production costs, improve production efficiency, maintain the overall aesthetic appeal and simplicity of the bags, and avoid additional costs.

Abstract
Description
Technical Field
[0001] This utility model relates to a zipper, and more specifically, to a composite zipper for bags. Background Technology
[0002] When traditional bag zippers are sewn onto the bag body, the seams are exposed on the zipper strip. To ensure the bag's overall appearance and simplicity, plastic strips are needed to cover the exposed seams, and binding is also required to cover the junction of the zipper strip and the bag body edge; otherwise, it will be uneven. However, this not only increases the manufacturing process but also raises production costs, resulting in an unsatisfactory overall effect. Therefore, this utility model proposes a composite zipper for bags. Utility Model Content
[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a composite zipper for bags.
[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: The composite zipper for bags and luggage involved in this utility model includes two rows of interlocking chain teeth. Each row of chain teeth is provided on a strip. The strip consists of a connecting part near the chain teeth and a sewn part away from the chain teeth. At least one of the sewn parts is provided with a baffle strip above it to cover the seam. The baffle strip extends along the length direction of the strip, and the side of the baffle strip near the chain teeth is connected to the strip. Below the sewn part where the baffle strip is provided, there is a covering strip that replaces the edging. The covering strip extends along the length direction of the strip, and the side of the covering strip near the chain teeth is connected to the strip.
[0005] The present invention is further configured such that a baffle strip is provided above both of the sutured parts to cover the suture thread.
[0006] The present invention is further configured such that: the baffle belt and the strip are integrated; the cover belt and the strip are integrated.
[0007] In summary, this utility model has the following beneficial effects:
[0008] 1. No additional plastic strip is needed to cover the seams, simplifying the manufacturing process and improving production efficiency.
[0009] 2. The overlay with edge covering function is integrally molded onto the zipper body, simplifying the manufacturing process and improving production efficiency.
[0010] 3. The gaps connecting the bag to the case are covered by the guard strips on the straps, making the bag look beautiful and simple overall.
[0011] 4. No additional costs are incurred for adding plastic strips and edge binding, thus reducing manufacturing costs. Attached Figure Description
[0012] Figure 1 This is a schematic diagram of the overall structure of this utility model. Detailed Implementation
[0013] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that these descriptions are only for further illustrating the features and advantages of this utility model, and not for limiting the patent claims of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.
[0014] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.
[0015] Example 1
[0016] See Figure 1 As shown, the composite zipper for bags involved in this embodiment includes two rows of interlocking chain teeth 1. Each row of chain teeth 1 is provided on a strip 2. The strip 2 is composed of a connecting part 21 near the chain teeth and a sewing part 22 away from the chain teeth. At least one of the sewing parts 22 is provided with a guard strip 23 to cover the seam. The guard strip 23 extends along the length direction of the strip 2. The side of the guard strip 23 near the chain teeth is connected to the strip 2. Below the sewing part 22 where the guard strip 23 is provided, there is a covering strip 24 to replace the edging. The covering strip 24 extends along the length direction of the strip 2. The side of the covering strip 24 near the chain teeth is connected to the strip 2.
[0017] Furthermore, both of the aforementioned suture portions 22 are provided with a guard strip 23 above them to cover the suture thread.
[0018] Furthermore, the baffle 23 is integral with the strip 2; the cover strip 24 is integral with the strip 2.
[0019] In this embodiment, the zipper is connected to the bag using the sewing part 22. After the connection is completed, the upper guard strip 23 can be used to cover the sewing thread, and the lower covering strip 24 can replace the outer binding to cover the intersection of the strip 2 and the edge of the bag.
[0020] The composite zipper for bags and luggage disclosed in this utility model eliminates the need for an additional plastic strip to cover the seams, simplifying the manufacturing process and improving production efficiency. The zipper body is integrally molded with a covering strip that provides edge covering, further simplifying the manufacturing process and improving production efficiency. Gaps connecting to the bag / suite are concealed by the covering strip, resulting in a neat and aesthetically pleasing overall appearance. Furthermore, it avoids the additional costs associated with adding plastic strips and edge coverings, reducing manufacturing costs, and offering comprehensive functionality and strong practicality.
[0021] Unless otherwise specified, in this utility model, terms such as "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the actual orientation or positional relationship shown. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe orientation or positional relationships in this utility model are for illustrative purposes only and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood in conjunction with the embodiments and according to the specific circumstances.
