Description

Technical Field

[0001] This utility model relates to the technology of zippers, and more particularly to a zipper opener (fastener openpart) and a zipper (fastener). Background Technology

[0002] A typical zipper usually consists of a zipper chain made up of a pair of zipper tapes and element columns mounted on the tapes, and a slider mounted on the zipper chain that opens or closes the element columns by sliding the slider along the zipper chain. Additionally, a zipper opener may be provided at the end of the zipper chain.

[0003] In the prior art, as an example, a zipper opening mechanism includes a retainer box located at the end of the zipper chain, a retainer pin located on one of a pair of zipper tapes and connected to the retainer box, and a separate pin located on the other of the pair of zipper tapes and capable of being inserted into or removed from the retainer box. The zipper chain is closed by inserting the separate pin into the retainer box, with the separate pin and retainer pin arranged side-by-side, and the zipper chain is opened by removing the separate pin from the retainer box. During the process of closing the zipper chain by inserting the separate pin into the retainer box, the zipper pull is typically slid to the end of the zipper chain, so that the zipper pull abuts against the front end of the retainer box and the retainer pin passes through one of the chain tooth channels inside the zipper pull. In this state, the separate pin passes through the other chain tooth channel inside the zipper pull and is inserted into the retainer box. Then, with the separate pin and retainer pin arranged side-by-side and the zipper chain closed, the zipper pull slides on the zipper chain. In particular, when using a zipper chain with coiled teeth, in order to accommodate the protruding coiled teeth located on one side of the zipper tape, the zipper pull is provided with a flange on the side corresponding to the coiled teeth for limiting the coiled teeth. That is, when the coiled teeth are located on the inside of the zipper tape, the zipper pull is mounted on the zipper chain with the flange facing the inside and slides relative to the zipper chain.

[0004] However, when the zipper pull is slid to the end of the zipper chain and approaches the zipper opener, the flange of the zipper pull may interfere with the protruding bar or the rib (the structure used to sew the zipper opener onto the zipper chain) that is laterally connected to the bar. This makes it difficult for the zipper pull to continue sliding to the front end of the socket. This not only obstructs the bar's passage through one of the zipper pull's internal tooth channels, causing the zipper pull to deflect and tilt, but also makes it difficult for the subsequent insert bar to pass through the other tooth channel inside the zipper pull and insert into the socket. Furthermore, the zipper pull also struggles to slide on the zipper chain after the insert bar has barely entered the socket and leaves the zipper opener. Thus, the zipper opener and the zipper with the zipper opener have poor operability. It is necessary to improve the structure of the zipper opener, especially the structure near the bar, to enhance the smoothness of operation during zipper pull sliding and bar passage. Utility Model Content

[0005] This invention provides a zipper opening component and a zipper, which can improve the smoothness of operation when sliding the zipper head and passing the zipper bar through the zipper head.

[0006] This utility model provides a zipper opener suitable for installation on a zipper chain including a pair of zipper tapes and a pair of coiled teeth disposed on the inner side of the zipper tapes, and comprising: a socket adapted to be disposed on the surface side and the inner side of the zipper tapes, and located at the end of the coiled teeth in the length direction; a base bar disposed on one side of the front end of the socket in the length direction in the width direction, and extending forward from the front end and protruding toward the end of the coiled teeth disposed on one of the pair of zipper tapes; a rib disposed on the outer side of the base bar in the width direction, and connected to the outer side of the socket in the width direction; and a gap portion formed at least between the base bar and the rib portion on the inner side corresponding to the coiled teeth, wherein the inner side corresponding to the coiled teeth is opposite to the surface side corresponding to the pull tab of the zipper pull applied to the zipper chain, and the dimension of the gap portion in the width direction corresponds to the dimension of the flange portion of the zipper pull applied to the zipper chain in the width direction.

[0007] In an embodiment of this utility model, the zipper opening member further includes a reinforcing part disposed in the gap and connected to the base bar.

[0008] In an embodiment of this utility model, the reinforcing part penetrates the zipper strip on the corresponding side in the thickness direction and extends to the inner side and the surface side.

[0009] In an embodiment of this utility model, the gap extends from the front end of the socket along the length direction between the seat bar and the rib, and the reinforcing part is disposed at the middle position in the length direction of the gap.

[0010] In an embodiment of this utility model, the dimension of the gap in the width direction is equal to the dimension of the flange of the slider in the width direction.

[0011] In an embodiment of this utility model, the dimension of the gap in the width direction is greater than the dimension of the flange of the pull head in the width direction and smaller than the dimension of the seat bar in the width direction.

[0012] In an embodiment of this utility model, the zipper opening member further includes: a plug, which is disposed toward the end of the coiled chain teeth of the other of the pair of zipper straps and can be inserted into the plug channel on the other side of the width direction of the front end portion in the length direction of the socket.

[0013] This utility model also provides a zipper, comprising: a zipper chain, including a pair of zipper tapes and a pair of coiled chain teeth disposed on the inner side of the zipper tapes; a zipper pull, mounted on the zipper chain, and having a flange portion disposed on a side edge in the width direction and a chain tooth channel planned by the flange portion; and a zipper opening member, mounted on the zipper chain.

[0014] In an embodiment of this utility model, when the zipper head slides relative to the zipper chain to near the zipper opening member, the zipper head moves toward the socket while the flange portion on the corresponding side passes through the gap and guides the seat bar into the zipper tooth channel on the corresponding side.

[0015] Based on the above, in the zipper opening member and zipper of this invention, the base bar is disposed on one side of the front end of the socket and extends forward and protrudes, the rib is disposed on the outer side of the base bar and connected to the outer side of the socket, and a gap is formed at least on the inner side between the base bar and the rib, and the size of the gap corresponds to the size of the flange provided on the zipper head. Thus, the thickness of the area between the base bar and the rib is reduced through the gap, and the zipper head will not be difficult to slide due to interference from the base bar or the rib laterally connected to the base bar on the flange. Therefore, the base bar can smoothly pass through the zipper tooth channel of the zipper head, and the zipper head can smoothly slide to abut the front end of the socket. Accordingly, the zipper opening member and zipper of this invention improve the smoothness of operation when sliding the zipper head and passing the base bar through the zipper head.

[0050] The exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. In particular, Figure 1 This is a planar schematic diagram of a zipper opening component according to an embodiment of the present invention, applied to the inner side of a zipper corresponding to a loop-type chain tooth row. Figure 2 yes Figure 1 The diagram shows a plan view of the zipper opening mechanism applied to the surface opposite to the inside of the zipper. Figure 3 yes Figure 1 The diagram shows a plan view of the zipper opener when the zipper pull has slid relative to the zipper chain and is close to the zipper opener. The following will use... Figures 1 to 3 This invention describes the specific structure of a zipper opening member 100 and a zipper 50 provided with the zipper opening member 100 according to an embodiment of the present invention, wherein... Figure 1 and Figure 2 The diagram shows the zipper chain 60 used with zipper 50 and the zipper opener 100, omitting the zipper pull 70, to illustrate the relative relationship between the zipper opener 100 and the zipper chain 60. Figure 3 The diagram shows the internal structure of the zipper pull 70 and the main parts of the zipper opening member 100, while omitting secondary parts such as the zipper chain 60 and the insert bar of the zipper opening member 100. However, the content shown above is only one example, and this utility model is not limited thereto and can be adjusted according to needs.

[0051] Please refer to Figures 1 to 3In this embodiment, the zipper 50 includes a zipper chain 60, a zipper pull 70, and a zipper opening member 100. The zipper chain 60 includes a pair of zipper tapes 62a and 62b, and a pair of coiled chain teeth 64a and 64b disposed on the inner side S1 of the zipper tapes 62a and 62b (e.g., ...). Figure 1 (As shown). The zipper pull 70 is mounted on the zipper chain 60 and has flanges 72a and 72b provided on the side edge in the width direction W (equivalent to the left-right direction here), and tooth channels 74a and 74b planned by the flanges 72a and 72b (as shown). Figure 3 (As shown). A zipper opener 100 is mounted on a zipper chain 60. The zipper opener 100 is adapted to be mounted on a zipper chain 60 including a pair of zipper tapes 62a, 62b and a pair of coiled chain teeth 64a, 64b disposed on the inner side S1 of the zipper tapes 62a, 62b, and includes a socket 110, a base bar 120, a rib 130A, and a gap 140A.

[0052] Specifically, in this embodiment, as Figure 1 and Figure 2 As shown, the zipper chain 60 has a pair of zipper strips 62a and 62b arranged in a sheet-like structure side by side. A pair of coiled chain teeth 64a and 64b are located on the inner side S1 of the zipper strips 62a and 62b, while the surface side S2 of the zipper strips 62a and 62b does not have chain teeth. When the zipper pull 70 is installed on the zipper chain 60, the side of the zipper pull 70 with the pull tab (operating surface / top surface) corresponding to the surface side S2. Therefore, the side of the zipper pull 70 without the pull tab (bottom surface) corresponds to the inner side S1 and accommodates the coiled chain teeth 64a and 64b. In this case, the zipper pull 70, for example, has flanges 72a and 72b on the side corresponding to the coiled chain teeth 64a and 64b (inner side S1) for limiting the movement of the coiled chain teeth 64a and 64b. In other words, when the coiled chain teeth 64a and 64b are arranged on the inner side S1 of the zipper tapes 62a and 62b, the zipper pull 70 is mounted on the zipper chain 60 with the flanges 72a and 72b corresponding to the inner side S1 and sliding relative to the zipper chain 60. A pair of zipper tapes 62a and 62b includes a surface side S2 (equivalent to the front) that serves as the operating surface (with a pull tab) of the zipper pull 70 after the zipper pull 70 is installed, and an inner side S1 (equivalent to the back) with the coiled chain teeth 64a and 64b. The inner side S1 corresponding to the coiled chain teeth 64a and 64b (e.g., ...) Figure 1 The surface side S2 corresponding to the pull tab (omitted here) provided on the zipper pull 70 applied to the zipper chain 60 (as shown) and the zipper pull 70 is provided with the zipper pull tab (omitted here). Figure 2(As shown) is the opposite side. Thus, the zipper 50, equipped with the zipper chain 60 as described above (including the coiled chain teeth 64a, 64b disposed on the inner side S1) and the zipper pull 70, is a concealed (inner-use) zipper. That is, the coiled chain teeth 64a, 64b are hidden on the inner side S1 (corresponding to the reverse side) of the pair of zipper tapes 62a, 62b and are not visible from the surface side S2 (corresponding to the front) of the zipper 50 and the product. However, this invention does not limit the specific structure and type of the zipper 50, that is, it does not limit the specific structure of the zipper chain 60, zipper pull 70, etc., which can be adjusted according to requirements.

[0053] Furthermore, in this embodiment, as Figures 1 to 3 As shown, the socket 110 is adapted to be disposed on the surface side S2 and the inner side S1 of the zipper straps 62a, 62b, and at the end of the coiled chain teeth 64a, 64b in the longitudinal direction L. As an example, the socket 110 is, for instance, a generally rectangular box structure located on the surface side S2 and the inner side S1, and spans a pair of zipper straps 62a, 62b across the zipper chain 60 in the width direction W. Correspondingly, a base bar 120 is disposed on one side of the width direction W of the front end portion 112 in the longitudinal direction L of the socket 110, and extends forward from the front end portion 112, protruding toward the end of the coiled chain teeth 64a of one of the pair of zipper straps 62a, 62b (e.g., zipper strap 62a). As an example, the base bar 120 is a generally rod-shaped structure located between the front end 112 of the socket 110 and the end of the corresponding coil-type chain tooth 64a, provided on the surface side S2 and the inner side S1 of the zipper tape 62a, and offset in the width direction W on the zipper tape 62a side of the socket 110. Furthermore, the rib 130A is provided on the outer side of the base bar 120 in the width direction W, and connected to the outer side 114A of the socket 110 in the width direction W. As an example, the rib 130A is a generally sheet-like structure extending laterally outward from the outer side 114A of the socket 110, and provided on the surface side S2 and the inner side S1 of the zipper tape 62a. Thus, the socket 110 and the base bar 120 of the zipper opener 100 can be fixed to the zipper tape 62a by the rib 130A and located at the end of the corresponding coil-type chain tooth 64a.

[0054] As an example, in this embodiment, such as Figures 1 to 3As shown, the zipper opening member 100 also includes a pusher 150. The pusher 150 is positioned toward the end of the coiled chain teeth (e.g., coiled chain teeth 64b) of the other of the pair of zipper tapes 62a and 62b (e.g., zipper tape 62b), and can be inserted into the pusher channel 116 on the other side of the front end portion 112 in the length direction L of the socket 110 (the side without the seat bar 120). As an example, the pusher 150 is, for example, a generally rod-shaped structure located at the end of the corresponding coiled chain teeth 64b and corresponding to the front end portion 112 of the socket 110, provided on the surface side S2 and the inner side S1 of the zipper tape 62b, and can be offset in the width direction W to the side of the zipper tape 62b into the socket 110. That is, a base bar 120 and a insertion bar channel 116 (shown as dashed lines) are respectively provided on opposite sides of the front end 112 of the socket 110 in the width direction W. Therefore, the zipper opening member 100 can close the zipper chain 60 (e.g., by inserting the insertion bar 150 into the socket 110 (in the insertion bar channel 116) and having the insertion bar 150 and the base bar 120 arranged side by side). Figure 1 and Figure 2 (as shown), and the zipper chain 60 is opened by removing the plug 150 from the socket 110.

[0055] In this embodiment, as Figure 3 As shown, during the process of inserting the plug 150 into the socket 110 to close the zipper chain 60, the zipper head 70 is typically slid to the end of the zipper chain 60, so that the zipper head 70 abuts against the front end 112 of the socket 110 and the seat bar 120 passes through one of the chain tooth channels 74a inside the zipper head 70. In this state, the plug 150 is then passed through as shown in the diagram. Figure 3 The path P, indicated by the dashed arrow, passes through another chain tooth channel 74b inside the zipper pull 70 and inserts into the socket (the insert bar channel 116). Then, with the insert bar 150 and the base bar 120 arranged side-by-side and the zipper chain 60 closed, the zipper pull 70 slides on the zipper chain 60 (e.g., ...). Figure 1 and Figure 2 The state is that the zipper pull 70 has moved forward and away from the zipper opener 100. Therefore, in the above operation, the smoothness of sliding the zipper pull 70 to the end of the zipper chain 60, so that the zipper pull 70 abuts against the front end 112 of the socket 110 and the seat bar 120 passes through one of the chain tooth channels 74a inside the zipper pull 70 is crucial. To this end, the zipper opener 100 and the zipper 50 are provided with a gap 140A to achieve smooth operation.

[0056] In detail, in this embodiment, such as Figures 1 to 3As shown, the gap 140A is formed at least on the inner side S1 corresponding to the coiled chain teeth 64a, 64b between the base bar 120 and the rib 130A, and the dimension of the gap 140A in the width direction W corresponds to the dimension of the flanges 72a, 72b provided on the zipper pull 70 applied to the zipper chain 60 in the width direction W. That is, when the socket 110, base bar 120, and rib 130A are provided on both the inner side S1 and the surface side S2 of the zipper chain 60, at least the portions of the base bar 120 and the rib 130A on the inner side S1 (the side with the coiled chain teeth 64a, 64b) are separated from each other by the gap 140A and are not connected to each other. Therefore, when the zipper opening member 100 is installed on the zipper chain 60, as Figure 1 As shown, the inner surface S1 of the zipper tape 62a on the side corresponding to the seat bar 120 is exposed through the gap 140A on the inner surface S1. Correspondingly, the portions of the seat bar 120 and the rib 130A on the surface side S2 can also be separated by the gap 140A and are not connected to each other. That is, when the zipper opening member 100 is installed on the zipper chain 60, as... Figure 2 As shown, the surface of the zipper tape 62a on the side corresponding to the seat bar 120 is exposed through the gap 140A on the surface side S2. This allows the zipper opening member 100 to have a reduced thickness at the surface side S2 location of the seat bar 120 and the rib 130A. However, in other embodiments not shown, the gap 140A may not be provided for the portion of the seat bar 120 and the rib 130A on the surface side S2. It is sufficient that the gap 140A is formed on the inner side S1 of the seat bar 120 and the rib 130A (the side corresponding to the location of the coiled chain teeth 64a, 64b and the flanges 72a, 72b of the zipper pull 70). This invention is not limited to this and can be adjusted according to requirements.

[0057] With the above settings, in the zipper opening member 100 and the zipper 50 of this embodiment, as follows: Figure 3As shown, the base bar 120 is disposed on one side of the front end portion 112 of the socket 110 and extends forward and protrudes. The rib portion 130A is disposed on the outer side of the base bar 120 and connected to the outer side portion 114A of the socket 110. The gap portion 140A is formed at least on the inner side S1 between the base bar 120 and the rib portion 130A, and the size of the gap portion 140A corresponds to the size of the flange portion 72a provided on the slider 70. In this way, the thickness of the portion between the base bar 130 and the rib portion 130A is reduced by the gap portion 140A, and the slider 70 will not be difficult to slide due to the interference of the flange portion 72a provided by the base bar 120 or the rib portion 130A that is laterally connected to the base bar 120. Therefore, the base bar 120 can smoothly pass through the chain tooth channel 74a of the slider 70, and the slider 70 can smoothly slide to abut the front end portion 112 of the socket 110. Accordingly, the zipper opening member 100 and the zipper 50 of this embodiment can improve the smoothness of operation when sliding the zipper head 70 and passing the seat bar 120 through the zipper head 70.

[0058] Similarly, in this embodiment, as Figures 1 to 3 As shown, when the zipper opener 100 is provided with a push bar 150, a rib 130B may also be provided on the outer side of the push bar 150 in the width direction W. The rib 130B is connected to the outer side 114B of the socket 110 in the width direction W. As an example, the rib 130B is a generally sheet-like structure that extends laterally outward from the outer side 114B of the socket 110, and is provided on the surface side S2 and the inner side S1 of the zipper tape 62b. In this way, the push bar 150 of the zipper opener 100 can be fixed to the zipper tape 62b by the rib 130B and located at the end of the corresponding coiled chain teeth 64b. In addition, a connecting portion 160 (e.g., connecting the push bar 150 and the rib 130B) can be formed on the inner side S1 corresponding to the coiled chain teeth 64a, 64b between the push bar 150 and the rib 130B. Figure 1 As shown), a gap 140B can be formed on the surface side S2 between the insert 150 and the rib 130B to separate the insert 150 and the rib 130B. That is, when both the inner side S1 and the surface side S2 of the zipper chain 60 are provided with structures such as the insert 150 and the rib 130B, the portions of the insert 150 and the rib 130B on the inner side S1 are connected by the connecting portion 160, and the portions of the insert 150 and the rib 130B on the surface side S2 are separated by the gap 140B and are not connected to each other. The connecting portion 160 is, for example, a thin, fleshy rib that is thinner than the insert 150 and the rib 130B, and its lower end 162 is approximately aligned with the rib 130B. Therefore, the lower end 162 of the connecting portion 160 provided on the inner side S1 protrudes from the lower end of the surface side S2 of the zipper tape 62b (e.g., Figure 2 (as shown), but not limited to this.

[0059] With the above settings, in this embodiment, as follows: Figures 1 to 3 As shown, with the zipper opener 100 installed on the zipper chain 60, as Figure 2 As shown, the surface of the zipper tape 62b on the side corresponding to the insertion bar 150 is exposed from the gap 140B of the surface side S2. Therefore, the thickness of the zipper opener 100 can be reduced at the location of the insertion bar 150 and the surface side S2 of the rib 130B. In contrast, when the zipper opener 100 is mounted on the zipper chain 60, as... Figure 1 As shown, the inner surface S1 of the zipper tape 62b on the side corresponding to the insert bar 150 is covered by the connecting portion 160 and is not exposed. Therefore, the zipper opening member 100 can improve structural strength on the inner surface S1 (the side with the coiled chain teeth 64a, 64b) of the insert bar 150 and rib 130B. However, in other embodiments not shown, the gap 140B may not be provided on the surface side S2 of the insert bar 150 and rib 130B. It is sufficient that the gap 140A is formed on the inner surface S1 (the side corresponding to the coiled chain teeth 64a, 64b and the flange portions 72a, 72b of the zipper pull 70). This invention is not limited to this and can be adjusted according to requirements.

[0060] Additionally, in this embodiment, as Figure 1 and Figure 2As shown, the zipper opening member 100 also includes a reinforcing portion 170A, which is disposed in the gap portion 140A and connected to the base bar 120. When the base bar 120 and the rib portion 130A both have gap portions 140A on their surface side S2 and inner side S1, the gap portions 140A on both sides are provided with reinforcing portions 170A. The reinforcing portion 170A is at least connected to the base bar 120, but may be connected to or separated from the rib portion 130A as needed. Here, the zipper opening member 100 is formed on the zipper chain 60 through processes such as injection molding. Mounting holes 180 (several are shown in the accompanying drawings as examples) are provided in the seat bar 120, ribs 130A and 130B, insert bar 150, and connecting portion 160. These holes are left after the injection molding process, where pressing pins press the zipper strips 62a and 64b, exposing the zipper strips 62a and 64b. However, this is not a limitation. Therefore, the reinforcing portion 170A formed in the gap portion 140A is preferably also formed on the zipper strip 62a through an injection molding process. For example, a through hole is provided in the zipper strip 62a, and injection material is injected into the through hole through the injection molding process to form the reinforcing portion 170A. Thus, the reinforcing portion 170A penetrates the corresponding side of the zipper strip 62a in the thickness direction and extends to the inner side S1 and the surface side S2. The reinforcing part 170A is roughly circular in the plan view (corresponding to the through hole on the zipper tape 62a), but its shape can be adjusted according to requirements (for example, the shape of the through hole formed by the aforementioned pressing pin), and this utility model is not limited thereto.

[0061] As an example, in this embodiment, such as Figure 1 and Figure 2 As shown, the gap 140A extends from the front end 112 of the socket 110 along the length direction L between the base 120 and the rib 130A. That is, the gap 140A is configured as an elongated groove-shaped region with a length greater than its width, and completely separates the base 120 and the rib 130A from the front end 112 (the root of the base 120) of the socket 110 to the top 122 of the base 120, thus opening towards the front. Correspondingly, the reinforcement 170A is positioned at the middle position in the length direction L of the gap 140A. That is, in the plan view, the distance of the reinforcement 170A relative to the front end 112 (the root of the base 120) of the socket 110 is approximately equal to the distance relative to the top 122 of the base 120. The middle position is not limited to the exact center of the gap 140A in the length direction L; the reinforcement 170A can also be positioned as follows: Figure 1As shown, the reinforcement 170A is closer to the top 122 of the base rod 120 than the front end 112 (the root of the base rod 120) of the socket 110 (and vice versa). However, the reinforcement 170A is not limited to being located in the middle of the gap 140A; it can provide reinforcement as long as it is located within the gap 140A. Thus, the zipper opening member 100 can improve its structural strength by using the reinforcement 170A in a small size without affecting the flange 72a, while still having the gap 140A. However, this invention does not limit the specific structure, arrangement, or presence of the reinforcement 170A of the gap 140A; these can be adjusted as needed.

[0062] Similarly, in this embodiment, as Figure 2 As shown, when the zipper opener 100 is provided with an insert 150 and a gap 140B is formed on the surface side S2 between the insert 150 and the rib 130B, a reinforcing portion 170B connected to the insert 150 can also be provided in the gap 140B. The reinforcing portion 170B is at least connected to the insert 150, but can be connected to or separated from the rib 130B as needed. The reinforcing portion 170B can be formed on the zipper tape 62b by an injection molding process, as described above for the reinforcing portion 170A. Thus, the reinforcing portion 170B penetrates the corresponding side of the zipper tape 62b in the thickness direction and extends to the inner side S1 and the surface side S2, and is further connected to the connecting portion 160 provided on the inner side S1. In this way, the zipper opener 100 can improve its structural strength by reinforcing it with the reinforcing portion 170B, even with the gap 140B provided. However, this utility model does not limit the specific structure, arrangement method, or whether the gap portion 140B and the reinforcing portion 170B are set, and they can be adjusted according to requirements.

[0063] Additionally, in this embodiment, as Figure 1 and Figure 2As shown, the dimension of the gap 140A in the width direction W (here, for example, the width) corresponds to the dimension of the flange portions 72a and 72b provided on the zipper pull 70 applied to the zipper chain 60 in the width direction W (here, for example, the width). For example, the dimension (width) of the gap 140A in the width direction W is approximately equal to or slightly larger than the dimension (width) of the flange portions 72a and 72b provided on the zipper pull 70 in the width direction W. As an example, the dimension (width) of the gap 140A in the width direction W is equal to the dimension (width) of the flange portions 72a and 72b of the zipper pull 70 in the width direction W, that is, the width of the gap 140A just allows the flange portion 72a to pass through. Alternatively, the width of the gap 140A in the width direction W is greater than the width of the flanges 72a and 72b of the slider 70 in the width direction W, but smaller than the width of the base bar 120 in the width direction W. That is, the width of the gap 140A is slightly larger than the width of the flange 72a to allow the flange 72a to pass through, but not wider than the base bar 120. Preferably, the width of the gap 140A in the width direction W is smaller than the width of the connecting portion 160 in the width direction W. The widths of the flanges 72a and 72b of the slider 70 in the width direction W are generally equal. If the widths of the flanges 72a and 72b of the slider 70 are different in the width direction W, the above description is based on the size of the flange 72a on the side corresponding to the gap 140A.

[0064] With the above settings, in this embodiment, as follows: Figure 3As shown, since the size (width) of the gap portion 140A in the width direction W is approximately equal to or slightly larger than the size (width) of the flange portions 72a and 72b provided on the zipper pull 70 in the width direction W, and is configured as a roughly elongated groove-shaped area, when the zipper pull 70 slides relative to the zipper chain 60 to approach the zipper opening member 100, the zipper pull 70 moves toward the socket 110 while the flange portion 72a on the corresponding side penetrates into the gap portion 140A and guides the seat bar 120 to penetrate into the zipper tooth channel 74a on the corresponding side. Thus, the gap 140A not only prevents the flange 72a of the slider 70 from being difficult to slide due to interference from the base bar 120 or the rib 130A laterally connected to the base bar 120, but also forms a narrow guide groove to further guide the flange 72a into the gap 140A. This provides a guiding effect that stabilizes the slider 70's posture when it moves downward, allowing the base bar 120 to smoothly pass through the chain tooth channel 74a of the slider 70, and enabling the slider 70 to smoothly slide to the front end 112 of the socket 110. However, it is sufficient that the gap 140A can guide the sliding of the flange 72a on the corresponding side of the slider 70 (i.e., the size of the gap 140A is approximately equal to or slightly larger than the size of the flange 72a). Similarly, when the zipper opening member 100 is provided with a push bar 150 and a gap 140B is also formed on the surface side S2 of the push bar 150 and the rib 130B, the gap 140B can also be configured as described above. However, as long as the dimension (width) of the gap 140B in the width direction W is greater than the flange 72b of the zipper pull 70, allowing the flange 72a to pass through, it is acceptable. This utility model is not limited to this and can be adjusted according to requirements.

[0065] Additionally, in this embodiment, as Figures 1 to 3 As shown, the zipper opener 100 has a recessed portion 124 at its top 122 that is recessed inward (opposite to the side of the rib 130A and the gap 140A). When the zipper chain 60 has a structure such as a zipper bar 120 on both the inner side S1 and the surface side S2, the zipper bar 120 and the rib 130A can both have recessed portions 124 on their inner side S1 and surface side S2 portions. Thus, as... Figure 1 and Figure 2 As shown, when the insert bar 150 is inserted into the socket 110 and is parallel to the base bar 120, and the zipper pull 70 slides relative to the zipper chain 60 to close the zipper chain 60, the chain tooth portion 152 provided at the top of the insert bar 150 engages with the last chain tooth of the coiled chain tooth row 64a on the opposite side (e.g., Figure 1 As shown), and the rear side abuts against the recessed portion 124 (both the inner side S1 and the surface side S2 are like this, as shown). Figure 1 and Figure 2 (As shown). Furthermore, as... Figure 3As shown, when the zipper pull 70 slides relative to the zipper chain 60 to near the zipper opener 100, while the zipper pull 70 moves smoothly toward the socket 110 guided by the gap 140A to the flange 72a, the dividing portion 76 provided inside the zipper pull 70 (located between the flanges 72a and 72b and dividing the chain tooth channels 74a and 72b) avoids the base bar 120 through the recess 124. Thus, the base bar 120, through the recess 124, has the effect of avoiding interference with the dividing portion 76, that is, the zipper pull 70 will not be difficult to slide due to the interference of the top 122 of the base bar 120 with the dividing portion 76. Therefore, the base bar 120 can smoothly pass through the chain tooth channel 74a of the zipper pull 70, and the zipper pull 70 can smoothly slide to the front end 112 that abuts against the socket 110. However, this utility model does not limit the specific structure of the recess 124 or whether it is provided or not; it can be adjusted according to requirements.

[0066] In summary, in the zipper opener and zipper of this invention, the base bar is located on one side of the front end of the socket and extends forward, the rib is located on the outside of the base bar and connected to the outside of the socket, and the gap is formed at least on the inner side between the base bar and the rib, with the size of the gap corresponding to the size of the flange of the zipper pull. Thus, the thickness of the area between the base bar and the rib is reduced through the gap, preventing the zipper pull from sliding due to interference from the base bar or the rib laterally connected to the base bar. Therefore, the base bar can smoothly pass through the zipper pull's tooth channel, and the zipper pull can smoothly slide to abut the front end of the socket. Preferably, the zipper opener also includes a reinforcing portion located in the gap and connected to the base bar, thereby increasing structural strength by reinforcing the flange through the gap with a small volume without affecting its position. Accordingly, the zipper opener and zipper of this invention improve the smoothness of operation when sliding the zipper pull and passing the base bar through the zipper pull.
