[0034] Reference Figures 1 to 9 A simplified top-stop zipper includes a zipper body 100 and a zipper head 200. The zipper body 100 includes two zipper straps 110, each strap including a base strap 111 and zipper teeth 112 disposed on the base strap 111. The zipper head 200 includes an upper plate 210, a lower plate 220, and a mechanism 230. The upper plate 210 and the lower plate 220 are connected via the mechanism 230. The zipper head 200 is connected to the zipper body 100, and the upper plate 210 and the lower plate 220 are located on opposite sides of the zipper body 100. The zipper body 100 has an upper stop end 120, and a clearance punch 130 is formed on the upper stop end 120 corresponding to the position of the zipper tooth 112. The two zipper straps 110 are fixed together on the upper side of the clearance punch 130 by a fixing structure 300. When the zipper head 200 is pulled to the upper stop end 120 of the zipper body 100, the movement 230 is housed in the clearance punch 130. It should be understood that the upper side of the clearance punch 130 is the side away from the beginning (i.e., the lower end) of the zipper.

[0035] When the zipper head 200 is closed to the upper stop end 120 of the zipper body 100, the clearance punch 130 can accommodate the zipper head 200's mechanism 230, thus preventing the mechanism 230 from directly inserting between the chain teeth 112 and affecting the zipper's flatness. The two zipper straps 110 on the upper side of the clearance punch 130 are fixed together by the fixing structure 300, thereby limiting the zipper head 200 and completing the upper stop function. The zipper described above, by opening the clearance punch 130 at the chain teeth 112 and fixing the two zipper straps 110 on the upper side of the clearance punch 130 by the fixing structure 300, forms a simple upper stop structure. This structure makes full use of the structure of the zipper body 100 itself, without the need for an additional complex upper stop seat structure, making it easy to manufacture and cost-effective.

[0036] In one embodiment, the two zipper straps 110 have teeth 112 on the upper side of the clearance punch 130 and engage with each other. The fixing structure 300 is used to fix the two zipper straps 110 after engagement. Using the above structure, the engagement of the zipper itself can be used to strengthen the mutual fixation of the two zipper straps 110 on the upper side of the clearance punch 130. It is conceivable that in some embodiments, the zipper straps 110 on the upper side of the clearance punch 130 may not have teeth 112, and the fixing structure 300 can directly fix the base strap 111.

[0037] In this embodiment, the fixing structure 300 is a fastener that passes through the zipper tape 110 for fixation. The fixing structure 300 is securely fixed by the fastener passing through the zipper tape 110. The fastener can be, for example, a rivet, a rivet, a sewing thread, etc.

[0038] In some embodiments, the fixing structure 300 is an adhesive structure that bonds the two zipper tapes 110 together. The fixing structure 300 is an adhesive structure, which is convenient to manufacture. The adhesive structure can be formed using, for example, glue, filler colloid, or injection molding colloid.

[0039] In some embodiments, the fixing structure 300 is a structure in which two zipper tapes 110 are heat-fused together. The fixing structure 300 adopts a heat-fused structure, which provides a firm fixation and good integrity.

[0040] It is understood that the fixing structure 300 is not limited to the embodiments exemplified above; any structure capable of fixing the two zipper straps 110 on the upper side of the clearance punch 130 together is acceptable. It is conceivable that the embodiments of the fixing structure 300 exemplified above can also be used in combination to strengthen the fixing, and those skilled in the art can configure it according to the actual situation.

[0041] In this embodiment, the relief punch 130 is adapted to the shape of the movement 230, thereby improving the fit between the zipper head 200 and the zipper body 100 and enhancing the flatness of the zipper. Of course, in some embodiments, the shape and structure of the relief punch 130 and the movement 230 can be configured appropriately according to actual conditions, and are not limited to the implementation shown in the accompanying drawings.

[0042] In this embodiment, the zipper is a sealed zipper, and the base band 111 includes a bottom band 1111 and a main sealing layer 1112 covering the front side of the bottom band 1111. When the zipper is closed, one end of the main sealing layer 1112 of the two zipper bands 110 abuts against each other and seals the two meshed chain teeth 112.

[0043] In this embodiment, a secondary sealing layer is provided at the relief punch 130. The secondary sealing layer cooperates with the zipper head 200 to seal the relief punch 130. By providing a secondary sealing layer at the relief punch 130, the sealing performance can be further improved, preventing the relief punch 130 from becoming a weak point in the seal.

[0044] In this embodiment, the secondary sealant layer is connected to the primary sealant layer 1112, thereby achieving better sealing.

[0045] In this embodiment, the secondary sealant layer can be placed on the hole wall, opening, etc. of the relief punch 130. The specific configuration can be made according to the actual situation, as long as it can seal and cooperate with the zipper head 200.

[0046] In this embodiment, the upper zipper plate 210 has an upper central protrusion 240 on its surface opposite to the lower zipper plate 220. The upper central protrusion 240 extends along the central axis of the zipper and is used to abut against the point where the main sealing adhesive layers 1112 of the two zipper straps 110 abut against each other. With the above structure, the upper central protrusion 240 can press against the point where the main sealing adhesive layers 1112 abut against each other, allowing them to fit more tightly and thus improving the sealing performance.

[0047] In this embodiment, the lower zipper plate 220 has a lower central protrusion 250 on its surface opposite to the upper zipper plate 210. The lower central protrusion 250 extends along the central axis of the zipper and is used to abut against the chain teeth 112 after the two zipper straps 110 are engaged. With the above structure, the lower central protrusion 250 can press against the chain teeth 112 after the zipper is closed, thereby limiting the chain teeth 112 and ensuring stability after zipping.

[0048] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
