Abstract
Description
Technical Field
[0001] This utility model relates to the field of zipper technology, specifically to a bag zipper. Background Technology
[0002] Luggage and suitcases typically use zippers to connect the two shells. However, in current technology, the edges of the two shells have cut surfaces that are directly exposed, which is both sharp and prone to scratches, and aesthetically unpleasing. Therefore, adhesive strips are usually sewn along the edges of the shells. Consequently, in actual luggage and suitcase production, both the zipper and adhesive strip need to be sewn along the edges of the shells, requiring a two-step process, which is inefficient. Utility Model Content
[0003] In order to overcome the shortcomings of the prior art, this utility model proposes a bag zipper.
[0004] To achieve the above-mentioned technical effects, the present invention adopts the following solution:
[0005] A zipper for bags includes a zipper fabric, on which a first strip opening is provided along its length. A first zipper tooth and a second zipper tooth are respectively sewn onto the zipper fabric on both sides of the first strip opening. The first zipper tooth and the second zipper tooth are engaged and connected. A first zipper head is provided on the first zipper tooth and the second zipper tooth.
[0006] Two adhesive strips are fixedly connected to the zipper fabric, and the two adhesive strips are located on both sides of the first strip opening;
[0007] The surface of the zipper fabric is provided with a first waterproof membrane layer.
[0008] In a preferred embodiment, the first waterproof membrane layer comprises one of a PE membrane, a PET membrane, or a PVC membrane.
[0009] In a preferred embodiment, the first waterproof membrane layer is bonded to the surface of the zipper fabric with waterproof adhesive.
[0010] In a preferred embodiment, a stretchable lining is integrally connected to one side of the zipper fabric. A second strip-shaped opening is provided through the stretchable lining along its length. The second strip-shaped opening is parallel to the first strip-shaped opening. A third zipper tooth and a fourth zipper tooth, sewn onto the stretchable lining, are respectively provided on the two sides of the second strip-shaped opening. The third zipper tooth and the fourth zipper tooth are engaged and connected. A second zipper head is provided on the third zipper tooth and the fourth zipper tooth. One of the two adhesive strips is located on the side of the first strip-shaped opening away from the second strip-shaped opening, and the other adhesive strip is located on the side of the second strip-shaped opening away from the first strip-shaped opening.
[0011] In a preferred embodiment, the surface of the telescopic tarpaulin is provided with a second waterproof membrane layer, which is integrally formed with the first waterproof membrane layer.
[0012] Compared with existing technologies, the beneficial effects are:
[0013] This utility model has a simple structure and is easy to use. Two adhesive strips are fixedly installed on the zipper of the bag, and the two adhesive strips correspond to the edges of the two bag shells. Therefore, after the zipper is sewn to the edge of the bag shell, the adhesive strips can directly abut against the edge of the bag shell. Only one sewing step is required in the production of the bag, which improves the efficiency of the bag production process. In addition, the waterproof membrane layer improves the waterproof performance of the bag zipper. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0018] A bag zipper includes a zipper fabric 1, on which a first strip opening is provided along its length. On the two sides of the first strip opening, a first zipper tooth 3 and a second zipper tooth 4 are respectively sewn onto the zipper fabric 1. The first zipper tooth 3 and the second zipper tooth 4 are engaged and connected, and a first zipper head is provided on the first zipper tooth 3 and the second zipper tooth 4.
[0019] Two adhesive strips 5 are fixedly connected to the zipper fabric 1. The adhesive strips 5 are fixed with glue. The two adhesive strips 5 correspond to the edges of the two boxes of the bag respectively. The two adhesive strips 5 are located on both sides of the first strip opening.
[0020] The surface of the zipper fabric 1 is provided with a first waterproof membrane layer.
[0021] Two adhesive strips 5 are fixedly installed on the zipper of the bag, and the two adhesive strips 5 correspond to the edges of the two bag shells. Therefore, after the zipper is sewn to the edge of the bag shell, the adhesive strips 5 can directly abut against the edge of the bag shell. Only one sewing step is required in the production of the bag, which improves the efficiency of the bag production process. In addition, the waterproof membrane layer improves the waterproof performance of the bag zipper.
[0022] In a preferred embodiment, the first waterproof membrane layer comprises one of a PE membrane, a PET membrane, or a PVC membrane.
[0023] In a preferred embodiment, the first waterproof membrane layer is bonded to the surface of the zipper fabric 1 with waterproof adhesive. The waterproof adhesive can not only bond the first waterproof membrane but also further improve the waterproof performance of the zipper fabric 1.
[0024] In a preferred embodiment, a stretchable lining 6 is integrally connected to one side of the zipper fabric 1. A second strip-shaped opening runs through the stretchable lining 6 along its length, parallel to the first strip-shaped opening. Third zipper teeth 8 and fourth zipper teeth 9, sewn onto the stretchable lining 6, are respectively provided along the two sides of the second strip-shaped opening. The third zipper teeth 8 and fourth zipper teeth 9 engage with each other, and each has a second zipper head. One of the two adhesive strips 5 is located on the side of the first strip-shaped opening away from the second strip-shaped opening, and the other adhesive strip 5 is located on the side of the second strip-shaped opening away from the first strip-shaped opening. By combining the main zipper and the stretchable lining 6 zipper into one piece, the main zipper and the stretchable lining 6 zipper can be sewn onto the bag with only one stitch.
[0025] In a preferred embodiment, the surface of the telescopic tarpaulin 6 is provided with a second waterproof membrane layer, which is integrally formed with the first waterproof membrane layer. The second waterproof membrane layer and the first waterproof membrane layer are the same and are both bonded and fixed by waterproof adhesive.
