Description

Technical Field

[0001] The utility model relates to the technology of the zipper (fastener) field, and in particular to a slider for the zipper. Background Art

[0002] A common zipper generally includes a zipper chain consisting of a pair of left and right fastener tapes and a plurality of chain elements mounted on the zipper tapes, and a zipper slider mounted on the zipper chain to open or close the chain elements by sliding. A tab pull or the like may also be mounted on the zipper slider to drive the slider to slide. The zipper slider includes a slider body and a tab mounting post mounted on the slider body. At least one end of the tab mounting post is engaged with the mounting surface of the slider body and is annular, so that the tab can be mounted via the tab mounting post.

[0003] In the prior art, there are various means of mounting the tab mounting post on the mounting surface of the slider body. Sometimes, it is considered to use ultrasonic waves or other joining means to install the tab mounting post. For example, the end of the tab mounting post is provided with a joining protrusion, and the mounting surface of the slider body is provided with a fitting groove for fitting the tab mounting post to pre-position it, and a joining portion located on the bottom surface of the fitting groove and joined to the joining protrusion. Thus, the joining protrusion provided at the end of the tab mounting post is melted by ultrasonic waves and joined to the joining portion in the fitting groove provided on the mounting surface of the slider body. However, such a practice will cause the joining protrusion provided at the end of the tab mounting post to produce excess material (for example, a melted portion) during the joining process and accumulate between the end of the tab mounting post and the joining portion in the fitting groove of the slider body, thereby easily forming burrs around the end of the tab mounting post. As such, it is necessary to improve the structure of the zipper slider to avoid the formation of burrs at the end of the tab mounting post. Utility Model Content

[0059] Reference will now be made in detail to exemplary embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Figure 1 This is a three-dimensional schematic diagram of a zipper slider according to an embodiment of the present invention. Figure 2 yes Figure 1 The partially exploded schematic diagram of the zipper slider shown is Figure 3 yes Figure 2 The zipper slider shown is a partially enlarged schematic diagram near the slider body.

Figure 6 yes Figure 1 The cross-sectional view of the zipper slider shown is cut along the width direction. Figures 1 to 6 The specific structure and installation method of the zipper slider 100 according to the embodiment of the present invention are described, but the present invention is not limited thereto.

[0060] Please refer to Figure 1 and Figure 2 In this embodiment, the zipper slider 100 includes a slider body 110 and a pull tab mounting post 120. The zipper slider 100 is suitable for mounting the slider body 110 on a zipper chain (not shown) to form a zipper, and is suitable for mounting the pull tab 102 (such as Figure 1 As shown by the dotted line). The slider body 110 has a mounting surface 110s. The pull-tab mounting post 120 is mounted on the mounting surface 110s of the slider body 110. At least one end portion of the pull-tab mounting post 120 in the longitudinal direction L (equivalent to the front-to-back direction) (for example, the front end portion E1 corresponding to the front side S1 and / or the rear end portion E2 corresponding to the rear side S2) is provided with a coupling protrusion 122, and the mounting surface 110s of the slider body 110 is provided with a coupling groove 111 for engaging the pull-tab mounting post 120, and a coupling portion 112 (such as the bottom surface 111s of the coupling groove 111) that is mutually engaged with the coupling protrusion 122. Figure 2 The dotted area in the middle of the engagement groove 111 is formed, and the receiving groove 113 is further recessed from the bottom surface 111s of the engagement groove 111. The receiving groove 113 is formed on the outer periphery of the engagement portion 112. However, the present invention does not limit the specific structure of the zipper slider 100, which can be adjusted according to needs.

[0061] Specifically, in this embodiment, Figure 1 and Figure 2 As shown, the slider body 110 of the zipper slider 100 is, for example, composed of an upper wing plate 114 and a lower wing plate 115 arranged opposite to each other in the vertical direction (equivalent to the height direction T), and a guide column 116 connecting the upper wing plate 114 and the lower wing plate 115 at the front side S1 in the longitudinal direction L (equivalent to the front-back direction), and the ends of the rear sides S2 of the upper wing plate 114 and the lower wing plate 115 are in an open state. Here, the mounting surface 110s of the slider body 110 is, for example, the upper surface of the upper wing plate 114, and the structures (for example, the fitting groove 111, the joint portion 112, the receiving groove 113) formed on the mounting surface 110s of the slider body 110 in the above and subsequent descriptions are all formed on the upper surface of the upper wing plate 114 (such as Figure 2 As shown). The fitting groove 111 is formed by extending along the length direction L on the mounting surface 110s of the slider body 110, and the engaging portion 112 and the receiving groove 113 are formed at at least one end of the fitting groove 111 (the end of the front side S1 and / or the end of the rear side S2) to correspond to the engaging protrusion 122 provided at the end of the pull-tab mounting column 120. Among them, the engaging portion 112 is a portion of the fitting groove 111 for engaging with the engaging protrusion 122 provided at the end of the pull-tab mounting column 120 (as shown). Figure 2The dotted area (e.g., the end of the bottom surface 111s of the engagement groove 111) is provided, for example, at the end of the bottom surface 111s of the engagement groove 111. The receiving groove 113 is a recessed portion of the engagement groove 111, further inwardly than the outer periphery of the engagement portion 112. In other words, the aforementioned engagement portion 112 and receiving groove 113 are provided on the engagement side (front side S1 and / or rear side S2) of the slider body 110. However, the present invention is not limited to the specific structure of the slider body 110; it can be adjusted as needed.

[0062] Furthermore, in this embodiment, if Figure 1 and Figure 2 As shown, at least one end portion (for example, the aforementioned front end portion E1 and / or rear end portion E2) of the pull-tab mounting post 120 of the zipper slider 100 in the longitudinal direction L is mounted on the mounting surface 110s of the slider body 110, so that the front end portion E1 of the pull-tab mounting post 120 corresponds to the front side S1 of the slider body 110 and the rear end portion E2 of the pull-tab mounting post 120 corresponds to the rear side S2 of the slider body 110. Here, the mounting surface 110s of the slider body 110 is, for example, the upper surface of the upper wing plate 114, and the pull-tab mounting post 120 is, for example, mounted on the upper surface of the upper wing plate 114. The middle portion of the pull-tab mounting post 120 bulges upward compared to the two opposite ends, thereby forming an annular structure on the mounting surface 110s of the slider body 110 (i.e., the upper surface of the upper wing plate 114). Thus, as Figure 1 The illustrated pull tab 102 can be mounted on a pull tab mounting post 120 to drive the slider body 110 to slide on a zipper chain (not shown). The engaging protrusion 122 is a raised structure (which can be a strip-shaped rib or a bump (not shown)) on the end (front end E1 and / or rear end E2) of the pull tab mounting post 120. In other words, the engaging protrusion 122 is provided at the engaging end (front end E1 and / or rear end E2) of the pull tab mounting post 120. However, the present invention is not limited to the specific structure of the pull tab mounting post 120, which can be adjusted as needed.

[0063] As an example, in this embodiment, if Figures 2 to 4As shown, the engaging groove 111 extends along the longitudinal direction L. The engaging portion 112 is formed at one end (the front side S1 and / or the rear side S2) of the engaging groove 111 in the longitudinal direction L. The engaging portion 112 corresponds to the shape of the engaging protrusion 122 and engages with the engaging protrusion 122. This description uses the example of mounting the tab mounting post 120 at both opposing ends (the front end E1 and the rear end E2) in the longitudinal direction L on the mounting surface 110s of the slider body 110. Therefore, the engaging protrusions 122 are provided at the opposing ends (the front end E1 and the rear end E2) in the longitudinal direction L of the tab mounting post 120, respectively. Furthermore, the mounting surface 110s of the slider body 110 is provided with two opposing engaging portions 112 located at opposing ends (the front side S1 and the rear side S2) in the longitudinal direction L of the engaging groove 111, and two opposing receiving grooves 113 formed on the outer peripheries of the opposing engaging portions 112. The engaging groove 111 extends in the length direction L and corresponds to two opposite ends of the pull-tab mounting post 120 . The pull-tab mounting post 120 is installed across the front side S1 and the rear side S2 of the slider body 110 .

[0064] Thus, in this embodiment, if Figures 2 to 4 As shown, the shape of the engaging groove 111 roughly corresponds to the shape of the tab mounting post 120, and the dimensions of the engaging groove 111 encompass the installation range of the tab mounting post 120, facilitating pre-positioning of the tab mounting post 120. Furthermore, two opposing engaging portions 112 are provided at opposite ends (the front side S1 and the rear side S2) of the engaging groove 111 in the longitudinal direction L, as well as two opposing receiving grooves 113 formed around the outer peripheries of the opposing engaging portions 112. These facilitate engagement with the engaging protrusions 122 provided at the opposite ends (the front end E1 and the rear end E2) of the tab mounting post 120. The opposing receiving grooves 113 respectively accommodate any excess material generated during the engagement process of the opposing engaging protrusions 122 (as described below). However, in other embodiments not shown, the tab mounting post 120 is not limited to being installed across the front side S1 and the rear side S2 of the slider body 110; it may also be installed on only one end of the slider body 110 or in the middle between the front side S1 and the rear side S2. Furthermore, the tab mounting post 120 may be mounted on the mounting surface 110s of the slider body 110 at only one end, thereby forming a suspended state. In this case, the mounting surface 110s may be provided with only one engaging portion 112 and one receiving groove 113. Furthermore, the shape of the engaging groove 111 is not limited to corresponding to the shape of the tab mounting post 120; it may also correspond to the shapes of opposite ends (i.e., two opposing engaging grooves of shorter length may be provided instead of a single, longer engaging groove 111). The present invention does not limit the relative position of the slider body 110 and the tab mounting post 120; such positions may be adjusted as needed.

[0065] In the prior art, there are various methods for mounting the tab mounting post 120 on the mounting surface 110s of the slider body 110. Sometimes, the tab mounting post 120 may be mounted using a joining method such as ultrasonic waves. For example, the end (front end E1 and / or rear end E2) of the tab mounting post 120 is provided with a joining protrusion 122, and the mounting surface 110s of the slider body 110 is provided with a fitting groove 111 for fitting the tab mounting post 120 for pre-positioning, and a joining portion 112 located on the bottom surface 111s of the fitting groove 111 and engaging with the joining protrusion 122. Thus, the joining protrusion 122 provided on the end (front end E1 and / or rear end E2) of the tab mounting post 120 is melted using ultrasonic waves and joined to the joining portion 112 within the fitting groove 111 provided on the mounting surface 110s of the slider body 110. This practice can cause excess material (e.g., a melted portion) to form during the joining process at the engaging protrusion 122 provided at the end (front end E1 and / or rear end E2) of the pull-tab mounting post 120. At this time, because the mounting surface 110s of the slider body 110 is provided with a receiving groove 113 formed on the periphery of the engaging portion 112, which is recessed further inward from the bottom surface 111s of the fitting groove 111, the excess material can fall into the receiving groove 113 formed on the periphery of the engaging portion 112 and will not accumulate between the end (front end E1 and / or rear end E2) of the pull-tab mounting post 120 and the engaging portion 112 within the fitting groove 111 of the slider body 110, thereby forming burrs protruding outward. However, the present invention does not limit the installation method of the pull-tab mounting post 120, which can be adjusted according to needs.

[0066] Through the above-mentioned arrangement, in the zipper slider 100 of the present embodiment, at least one end portion (the front end portion E1 and / or the rear end portion E2) of the pull-tab mounting column 120 in the longitudinal direction L is provided with a coupling protrusion 122, and the mounting surface 110s of the slider body 110 is provided with a coupling groove 111 for engaging the pull-tab mounting column 120, a coupling portion 112 located on the bottom surface 111s of the coupling groove 111 and engaged with the coupling protrusion 122, and a receiving groove 113 that is further recessed inward from the bottom surface 111s of the coupling groove 111, and the receiving groove 113 is formed on the outer periphery of the coupling portion 112. In this way, when the pull-tab mounting post 120 is engaged with the engaging groove 111 and the engaging protrusion 122 is engaged with the engaging portion 112, even if the engaging protrusion 122 produces excess material during the joining process (for example, by melting the engaging protrusion 122 using ultrasound), the excess material can be accommodated in the receiving groove 113, which is recessed further inward from the bottom surface 111s of the engaging groove 111 and formed on the outer periphery of the engaging portion 112, without protruding from the engaging groove 111 and forming burrs around the pull-tab mounting post 120. Thus, the zipper slider 100 can avoid the formation of burrs and improve its aesthetics. Furthermore, when a joining method other than ultrasound is used, if the engaging protrusion 122 produces excess material during the joining process, the excess material can also be accommodated in the receiving groove 113, without protruding from the engaging groove 111 and forming burrs around the pull-tab mounting post 120, thereby affecting the aesthetics of the zipper slider 100. Furthermore, even if the joining means adopted does not produce excess material, the zipper slider 100 made of the slider body 110 with the receiving groove 113 is not excluded. In this way, the zipper slider 100 is applicable to various different installation means.

[0067] Furthermore, in this embodiment, if Figure 2 and Figure 3 As shown, at least a portion of the receiving groove 113 is formed along the inner edge of the fitting groove 111 to distinguish the joint portion 112 in the fitting groove 111. That is, the receiving groove 113 that is further recessed from the bottom surface 111s of the fitting groove 111 is, for example, a strip-shaped groove formed along the inner edge of the fitting groove 111, thereby distinguishing the joint portion 112 (such as the mounting surface 110s) separated from the mounting surface 110s of the slider body 110 in the fitting groove 111. Figure 2The receiving groove 113 is formed between the inner edge of the fitting groove 111 and the joint portion 112, and is located on the outer periphery of the joint portion 112. In this way, the receiving groove 113 can increase the height difference between the inner edge of the fitting groove 111 and the mounting surface 110s of the slider body 110, and more effectively accommodate the excess material of the engaging protrusion 122 during the engagement process of the engaging protrusion 122 of the pull-tab mounting post 120 (that is, the excess material is unlikely to fall into a position further outward than the inner edge of the fitting groove 111 and the receiving groove 113). However, in other embodiments not shown, the receiving groove 113 can also be formed on the bottom surface 111s within the fitting groove 111, rather than along the inner edge of the fitting groove 111. As long as the receiving groove 113 is formed inward from the bottom surface 111s within the fitting groove 111 and is formed on the outer periphery of the joint portion 112, it will be sufficient. The present invention is not limited to this and can be adjusted according to needs.

[0068] Furthermore, in this embodiment, if Figure 2 and Figure 3 As shown, the mounting surface 110s of the slider body 110 is further provided with a first positioning post 117a and a second positioning post 117b for positioning the ends (front end E1 and / or rear end E2) of the pull-tab mounting post 120. The first positioning post 117a and the second positioning post 117b are arranged along the length direction L on one end side (front side S1 and / or rear side S2) of the interlocking groove 111. The first positioning post 117a is located in the joint 112, and the second positioning post 117b is located on the inner edge of the joint 112. In this way, the first positioning post 117a and the second positioning post 117b can be used to pre-position the pull-tab mounting post 120 in the interlocking groove 111 (as described later). Furthermore, by employing the first and second positioning posts 117a, 117b, arranged along the longitudinal direction L, the ends (front end E1 and / or rear end E2) of the pull-tab mounting post 120 can be pre-positioned in both the longitudinal direction L and the width direction W. However, in other embodiments not shown, only the first or second positioning post 117a, 117b may be provided, or both the first and second positioning posts 117a, 117b may be omitted, with the pull-tab mounting post 120 pre-positioned by the wall formed by the height difference between the inner edge of the engaging groove 111 and the mounting surface 110s of the slider body 110. The present invention does not limit the specific structure, location, or presence of the first and second positioning posts 117a, 117b, and these can be adjusted as needed.

[0069] In addition, in this embodiment, Figure 2 and Figure 3As shown, the receiving groove 113 includes a first receiving groove 113a formed on the outer end side of the joint 112 in the longitudinal direction L, and a pair of second receiving grooves 113b formed on the opposite end sides in the width direction W (equivalent to the left and right direction) of the joint 112, and the first receiving groove 113a and the pair of second receiving grooves 113b are connected to each other and at least partially surround the outer periphery of the joint 112. In addition, the receiving groove 113 also includes a third receiving groove 113c formed between the first positioning column 117a and the second positioning column 117b. Among them, the first receiving groove 113a and the third receiving groove 113c are, for example, strip grooves extending along the width direction W, and the pair of second receiving grooves 113b are, for example, strip grooves extending along the longitudinal direction L. The first receiving groove 113a, the pair of second receiving grooves 113b, and the third receiving groove 113c distinguish the joint 112 (such as Figure 3 The receiving groove 113 surrounds the first positioning post 117a and corresponds to one side of the second positioning post 117b in the joint portion 112. In this way, the receiving groove 113 can more effectively receive the excess material of the joint protrusion 122 in the width direction W and the length direction L during the joint process of the pull-tab mounting post 120.

[0070] Furthermore, in this embodiment, if Figure 2 and Figure 3 As shown, the pair of second receiving grooves 113b extend further in the opposite direction to the first receiving groove 113a than the third receiving groove 113c, and are located on opposite sides of the second positioning column 117b in the width direction W, and the pair of second receiving grooves 113b and the third receiving groove 113c partially surround the second positioning column 117b. In this way, the length and coverage of the strip grooves serving as the pair of second receiving grooves 113b can be effectively increased, so that the receiving grooves 113 can more effectively accommodate the excess material of the engaging protrusion 122 in the width direction W and the length direction L during the engagement process of the engaging protrusion 122 of the pull-tab mounting column 120. Similarly, as Figure 2 and Figure 3 As shown, the mounting surface 110s of the slider body 110 further comprises a recess 118 recessed inward from the bottom surface of the first receiving groove 113a. The recess 118 is located at the center of the first receiving groove 113a in the width direction W. Specifically, the deeper (inwardly recessed) recess 118 is provided at the center of the strip-shaped groove serving as the first receiving groove 113a. This effectively increases the volume of the strip-shaped groove serving as the first receiving groove 113a, allowing the receiving groove 113 to more effectively accommodate the excess material of the engaging protrusion 122 of the pull tab mounting post 120 in both the width direction W and the length direction L during the engagement process.

[0071] Here, although Figure 2 and Figure 3The third receiving groove 113c shown in the figure is not connected to the pair of second receiving grooves 113b. However, in other embodiments not shown, the third receiving groove 113c may be connected to the pair of second receiving grooves 113b. Alternatively, the pair of second receiving grooves 113b may not extend in a direction opposite to the first receiving groove 113a compared to the third receiving groove 113c, so that the receiving groove 113 forms a square structure surrounding the first positioning post 117a. Alternatively, the third receiving groove 113c may be provided on the inner side of the second positioning post 117b (on the side opposite to the first positioning post 117a), so that the receiving groove 113 forms a square structure surrounding the first positioning post 117a and the second positioning post 117b. Alternatively, only the first receiving groove 113a and / or the pair of second receiving grooves 113b may be provided, and the third receiving groove 113c may be omitted. Alternatively, the recess 118 may be omitted. Furthermore, when installing the pull-tab mounting post 120 at its two opposite ends (front end E1 and rear end E2), identical first and second positioning posts 117a and 117b, recesses 118, and receiving slots 113 (a first receiving slot 113a, a pair of second receiving slots 113b, and a third receiving slot 113c) are provided at the opposite ends (front side S1 and rear side S2) of the fitting slot 111 in the longitudinal direction L. However, different configurations are also possible. The present invention does not limit the specific shape or location of the receiving slots 113, which can be adjusted as needed.

[0072] Furthermore, in this embodiment, if Figure 2 and Figure 4 As shown, corresponding to the above-described arrangement on the mounting surface 110s of the slider body 110, the ends (front end E1 and / or rear end E2) of the tab mounting post 120 are further provided with positioning holes 124 corresponding to the first positioning posts 117a and positioning grooves 126 corresponding to the second positioning posts 117b. The positioning holes 124 are located in the end of the tab mounting post 120, and the positioning grooves 126 are located at the inner edge of the end of the tab mounting post 120. In this way, the positioning holes 124 and positioning grooves 126 can be used to engage the first positioning posts 117a and the second positioning posts 117b, pre-positioning the tab mounting post 120 in the engagement groove 111. However, if the slider body 110 omits the first positioning posts 117a and / or the second positioning posts 117b, the positioning holes 124 and / or positioning grooves 126 can also be omitted from the tab mounting post 120. The present invention does not limit the specific structure, location, or whether the positioning hole 124 and the positioning slot 126 are provided, and they can be adjusted according to needs.

[0073] In addition, in this embodiment, Figure 2 and Figure 4As shown, the engaging protrusion 122 includes a first engaging protrusion 122a formed on the outer end side of the positioning hole 124 in the longitudinal direction L, a pair of second engaging protrusions 122b formed on opposite ends of the positioning hole 124 in the width direction W, and a third engaging protrusion 122c formed between the positioning hole 124 and the positioning groove 126. The first engaging protrusion 122a, the pair of second engaging protrusions 122b, and the third engaging protrusion 122c are connected to each other and surround the positioning hole 124. The first engaging protrusion 122a and the third engaging protrusion 122c are, for example, strip-shaped ribs extending along the width direction W, and the pair of second engaging protrusions 122b are, for example, strip-shaped ribs extending along the longitudinal direction L. The first engaging protrusion 122a, the pair of second engaging protrusions 122b, and the third engaging protrusion 122c are, for example, formed on the end surfaces of the side walls constituting the positioning hole 124 and the positioning groove 126. Thus, when the ends (front end E1 and / or rear end E2) of the pull-tab mounting post 120 are provided with positioning holes 124 and other structures, configuring the engaging protrusions 122 as connected strip-shaped ribs that surround the positioning holes 124 can increase the engagement area of the engaging protrusions 122 on the end of the pull-tab mounting post 120. Furthermore, the pair of second engaging protrusions 122b extend in a direction opposite to the first engaging protrusion 122a compared to the third engaging protrusion 122c, corresponding to opposite sides of the positioning groove 126 in the width direction W. The pair of second engaging protrusions 122b and the third engaging protrusion 122c partially surround the positioning groove 126. This effectively increases the length and coverage of the strip-shaped ribs serving as the pair of second engaging protrusions 122b, thereby further effectively increasing the engagement area of the engaging protrusion 122 on the end of the pull-tab mounting post 120.

[0074] Here, although Figure 2 and Figure 4The third engaging protrusion 122c shown in the figure is connected to the pair of second engaging protrusions 122b, but in other embodiments not shown, the third engaging protrusion 122c may not be connected to the pair of second engaging protrusions 122b. Alternatively, the pair of second engaging protrusions 122b may not extend in a direction opposite to the first engaging protrusion 122a compared to the third engaging protrusion 122c, so that the engaging protrusion 122 forms a square-shaped structure of the positioning hole 124. Alternatively, the third engaging protrusion 122c may be provided on the inner side of the positioning groove 126 (opposite to the side of the first positioning column 117a), so that the engaging protrusion 122 forms a square-shaped structure surrounding the positioning hole 124 and the positioning groove 126 (in this case, it can be a positioning hole). Alternatively, only the first engaging protrusion 122a and / or the pair of second engaging protrusions 122b may be provided, and the third engaging protrusion 122c may be omitted. Alternatively, if the tab mounting post 120 omits the positioning holes 124 and / or positioning grooves 126, the engaging protrusion 122 is not limited to being strip-shaped or ring-shaped; it can also be configured as a block located in the center of the end surface of the tab mounting post 120. Furthermore, when mounting the tab mounting post 120 at its two opposite ends (the front end E1 and the rear end E2), the same positioning holes 124, positioning grooves 126, and engaging protrusions 122 can be provided at both ends, or they can have different configurations. The present invention does not limit the specific shape or location of the engaging protrusion 122; it can be adjusted as needed.

[0075] Through the above settings, in this embodiment, if Figure 5 and Figure 6 As shown, when the pull-tab mounting post 120 is mounted on the mounting surface 110s of the slider body 110, the positioning hole 124 corresponds to the first positioning post 117a and the positioning groove 126 corresponds to the second positioning post 117b, so that the pull-tab mounting post 120 is pre-positioned in the fitting groove 111 of the mounting surface 110s of the slider body 110. In addition, the first engaging protrusion 122a engages with the portion of the engaging portion 112 located between the first positioning post 117a and the first receiving groove 113a (as shown in FIG. Figure 5 As shown) and adjacent to the first receiving groove 113a, a pair of second engaging protrusions 122b engages with the portion of the engaging portion 112 between the outer periphery of the first positioning column 117a in the width direction W and the pair of second receiving grooves 113b (as shown) Figure 6 As shown) and adjacent to a pair of second receiving grooves 113b, and the third engaging protrusion 122c is engaged with the portion of the engaging portion 112 between the first positioning post 117a and the second positioning post 117b (as shown) Figure 5As shown) and adjacent to the third receiving groove 113c. In this way, the receiving groove 113 can more effectively receive the excess material of the engaging protrusion 122 in the width direction W and the length direction L during the engaging process of the engaging protrusion 122 of the pull-tab mounting column 120.

[0076] Specifically, in this embodiment, Figure 5 and Figure 6 As shown, when the engaging protrusion 122 of the tab mounting post 120 is engaged with the engaging portion 112 of the slider body 110, the receiving groove 113 is located at the periphery of the contact point P of the engaging protrusion 122 with the engaging portion 112. Furthermore, the outer peripheral end 122e of the engaging protrusion 122 partially overlaps with the inner peripheral edge 113s of the receiving groove 113 in the height direction T. Here, the inner peripheral edge 113s of the receiving groove 113 refers to the portion of the inner sidewall of the receiving groove 113 that is recessed downward in the height direction T from the bottom surface of the engaging portion 112 (corresponding to a portion of the bottom surface 111s of the fitting groove 111). The outer peripheral end 122e of the engaging protrusion 122 refers to the portion of the engaging protrusion 122 that is inclined downward from the end surface (e.g., the inner sidewall surrounding the positioning hole 124) of the end portion (front end E1 or rear end E2) of the tab mounting post 120. Thus, when the engaging protrusion 122 of the pull-tab mounting post 120 and the engaging portion 112 of the slider body 110 are engaged with each other, the contact end point P of the engaging protrusion 122 contacts the engaging portion 112, and the receiving groove 113 is located outside the contact end point P of the engaging protrusion 122 that engages with the engaging portion 112. As a result, the contact end point P of the engaging protrusion 122 is closer to the inside of the engaging portion 112 than the inner end side (inner peripheral edge) of the receiving groove 113. Furthermore, at least a portion (e.g., the outer peripheral end) of the engaging protrusion 122 is located above at least a portion (e.g., the inner peripheral edge) of the receiving groove 113, partially overlapping them in the height direction T.

[0077] As an example, in this embodiment, when the engaging protrusion 122 of the pull tab mounting column 120 and the engaging portion 112 of the slider body 110 are engaged with each other, as shown in FIG. Figure 5 As shown, the contact endpoint P of the first engaging protrusion 122a in the engaging protrusion 122 contacts the engaging portion 112, and the contact endpoint P of the first engaging protrusion 122a is closer to the inner side of the engaging portion 112 in the length direction L than the inner end side (inner peripheral edge portion) of the first receiving groove 113a located on the periphery of the contact endpoint P of the first engaging protrusion 122a. In addition, at least a portion (e.g., the outer peripheral end portion) of the first engaging protrusion 122a is located above at least a portion (e.g., the inner peripheral edge portion) of the first receiving groove 113a and partially overlaps in the height direction T. Similarly, as Figure 6As shown, the contact endpoints P of a pair of second engaging protrusions 122b in the engaging protrusion 122 contact the engaging portion 112, and the contact endpoints P of the second engaging protrusions 122b are closer to the inner side in the width direction W of the engaging portion 112 than the inner end sides (inner peripheral edges) of a pair of second receiving grooves 113b located on the periphery of the contact endpoints P of the second engaging protrusions 122b. Furthermore, at least a portion (e.g., the outer peripheral ends) of the pair of second engaging protrusions 122b are located above at least a portion (e.g., the inner peripheral edges) of the pair of second receiving grooves 113b and partially overlap in the height direction T. In addition, although the third engaging protrusion 122c in the engaging protrusion 122 and the third receiving groove 113c in the receiving groove 113 are slightly different from the aforementioned configuration, as shown in FIG. Figure 5 As shown, the contact endpoint of the third engaging protrusion 122c contacts the engaging portion 112, and the contact endpoint of the third engaging protrusion 122c is closer to the engaging portion 112 than the third receiving groove 113c. In addition, at least a portion of the third engaging protrusion 122c is located above at least a portion of the third receiving groove 113c, partially overlapping in the height direction T.

[0078] Through the above configuration, in this embodiment, when the engaging protrusion 122 of the tab mounting post 120 and the engaging portion 112 of the slider body 110 are engaged with each other, using ultrasonic bonding, the contact point P of the engaging protrusion 122 contacts the engaging portion 112 before ultrasonic bonding, resulting in the above-described configuration. After ultrasonic bonding, the contact point P of the engaging protrusion 122 melts away, and the melted portion of the engaging protrusion 122 forms a residual material that falls (flows) into the receiving groove 113 located further outward of the engaging portion 112 and further downward in the height direction T than the contact point P of the engaging protrusion 122. In this manner, even if residual material (e.g., a melted portion) is generated during the bonding process, it can smoothly fall (flow) into the receiving groove 113 formed on the outer periphery of the engaging portion 112, preventing the formation of burrs. However, the present invention is not limited to the above-described configuration, as long as any excess material (e.g., melted portion) generated during the joining process of the engaging protrusion 122 can be accommodated in the receiving groove 113, which is recessed further inward from the bottom surface 111s of the fitting groove 111 and formed on the outer periphery of the engaging portion 112. Furthermore, even if the joining method employed does not generate excess material, the zipper slider 100 constructed using the slider body 110 provided with the receiving groove 113 is not precluded. The present invention does not limit the mounting method of the pull tab mounting post 120, which can be adjusted as needed.

[0079] In summary, in the zipper slider of the present invention, at least one end portion of the pull-tab mounting post in the longitudinal direction is provided with a coupling protrusion, and the mounting surface of the slider body is provided with a coupling groove for engaging the pull-tab mounting post, a coupling portion located at the bottom surface of the coupling groove and engaging with the coupling protrusion, and a receiving groove recessed further inward from the bottom surface of the coupling groove, wherein the receiving groove is formed on the periphery of the coupling portion. In this way, when the pull-tab mounting post is engaged in the coupling groove and the coupling protrusion and the coupling portion are engaged with each other, even if the coupling protrusion generates residual material during the engagement process (for example, by melting the coupling protrusion using ultrasound), the residual material can be accommodated in the receiving groove recessed further inward from the bottom surface of the coupling groove and formed on the periphery of the coupling portion, without protruding from the coupling groove and forming burrs around the pull-tab mounting post. Preferably, at least a portion of the receiving groove is formed along the inner edge of the fitting groove to demarcate the joining portion within the fitting groove. This allows excess material to easily fall into the receiving groove during the joining process, thereby preventing burrs from forming around the pull-tab mounting post. Thus, the zipper slider of the present invention can avoid burrs and improve its aesthetics.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
