Description

Technical Field

[0001] The utility model relates to the technology in the field of fasteners, in particular to a stopper for a fastener and a fastener applying the stopper for the fastener. Background Art

[0002] A common fastener usually includes a fastener chain composed of a pair of left and right fastener tapes and a plurality of elements mounted on the fastener tapes, and a slider mounted on the fastener chain and opening or closing the elements by sliding. Among them, a stopper for the fastener may be provided at the end in the length direction of the fastener chain as a stop point for the slider to slide on the fastener chain. When the slider slides on the fastener chain towards the end until at least a part of the stopper for the fastener enters the element channel of the slider, the slider cannot slide further.

[0003] However, in the prior art, sometimes a lock pin for interfering with the fastener tape is provided inside the slider. In this case, when the slider slides on the fastener chain until at least a part of the stopper for the fastener enters the element channel, the lock pin provided inside the slider may contact the surface of the stopper for the fastener, and it is easy to cause damage to the stopper for the fastener. Furthermore, the stopper for the fastener is easily cracked due to damage, and further falls off near the cord of the fastener tape. Thus, it is necessary to improve the structure of the stopper for the fastener to avoid damage and cracking of the stopper for the fastener, thereby enhancing the structural strength of the stopper for the fastener and the applied fastener. Summary of the Utility Model

[0004] The utility model provides a stopper for a fastener and a fastener, which can avoid damage and cracking of the stopper for the fastener and enhance the structural strength.

[0005] The present utility model provides a stopper for a zipper, which is adapted to be installed at the end of a zipper chain and includes: a main body portion installed on a pair of zipper tapes of the zipper chain to join the two; a stopper portion located on one side of the main body portion in the width direction and extending from a first end of the main body portion in the length direction toward a first side in the length direction; an inclined portion located at the center of the main body portion in the width direction and recessed and extending from the first end of the main body portion toward the first side in the length direction; and a thick portion located on the other side of the main body portion in the width direction and extending from the first end of the main body portion toward the first side in the length direction, wherein the inclined portion has an inclined surface that gradually increases in thickness from the first side toward a second side opposite to the first side in the length direction and slopes upward, and the thickness of the end portion of the thick portion on the first side in the length direction is greater than the thickness of the end portion of the inclined portion on the first side in the length direction.

[0006] In an embodiment of the present utility model, the thickness of the end portion of the thick portion on the first side in the length direction is less than the thickness of other portions of the thick portion.

[0007] In an embodiment of the present utility model, the length of the stopper portion in the length direction is greater than the length of the thick portion in the length direction, and the end portion of the inclined portion connected to the stopper portion in the width direction is closer to the first side in the length direction than the end portion of the inclined portion connected to the thick portion in the width direction.

[0008] In an embodiment of the present utility model, the inclined surface extends more toward the thick portion than the center line in the width direction.

[0009] In an embodiment of the present utility model, the inclined surface has a side edge located on the first side in the length direction and connecting the stopper portion and the thick portion, and the lowest point of the inclined surface closest to the bottom in the thickness direction passes through the side edge.

[0010] In an embodiment of the present utility model, the distance from the lowest point along the side edge to the thick portion is greater than the distance from the lowest point along the side edge to the stopper portion, and the inclination from the lowest point along the side edge to the thick portion is less than the inclination from the lowest point along the side edge to the stopper portion.

[0011] In an embodiment of the present utility model, the inclined surface is formed on one side of the inclined portion in the thickness direction.

[0012] The present utility model also provides a zipper, comprising: a zipper chain including a pair of zipper tapes extending along a length direction, and a plurality of chain teeth arranged side by side along the length direction on the zipper tapes; a slider mounted on the zipper chain and sliding on the zipper chain to open or close the chain teeth of the pair of zipper tapes; and a zipper stopper mounted at the end of the zipper chain.

[0013] In an embodiment of the present utility model, each of the pair of zipper tapes includes a core wire disposed on the inner edge, and the stopper portion and the thick portion respectively cover the core wires of the pair of zipper tapes.

[0014] In an embodiment of the present utility model, the zipper stopper is mounted on opposite side surfaces of the zipper tape in the thickness direction.

[0015] Based on the above, in the zipper stopper and the zipper of the present utility model, the zipper stopper includes a main body portion, a stopper portion, an inclined portion, and a thick portion, wherein the inclined portion has an inclined surface that slopes upward from a first side toward a second side in the length direction, and the thickness of the thick portion at the end on the first side is greater than the thickness of the inclined portion at the end on the first side. Thus, when the slider slides on the zipper chain until at least a part of the zipper stopper enters the chain tooth channel, the locking claws provided on the inner side of the slider enter the recessed area formed by the inclined surface of the inclined portion or move upward along the inclined surface, without causing damage to the zipper stopper. Moreover, a thick portion with a relatively large thickness is provided on the side of the end of the inclined portion where the recessed area is formed, thereby further enhancing the structural strength of the zipper stopper. Accordingly, the zipper stopper and the zipper of the present utility model can avoid damage and cracking of the zipper stopper and enhance the structural strength.

[0016] To make the above features and advantages of the present utility model more obvious and understandable, specific embodiments are hereinafter given and described in detail in conjunction with the accompanying drawings as follows. BRIEF DESCRIPTION OF THE DRAWINGS

[0059] Reference will now be made in detail to the exemplary embodiments of the present invention, and examples of the exemplary embodiments are illustrated in the accompanying drawings. Among them, Figure 1 is a three-dimensional schematic diagram of a zipper according to an embodiment of the present invention, Figure 2 is Figure 1 a schematic cross-sectional view in the length direction of the zipper shown when the slider slides to the zipper stopper, Figure 3 is Figure 1 a partial schematic diagram of the area of the zipper where the zipper stopper is installed, Figure 4 is Figure 3 a top schematic diagram of the zipper stopper shown, Figure 5 is Figure 3 a side schematic diagram of the zipper stopper shown, Figure 6 is Figure 3 a schematic cross-sectional view of the zipper stopper shown cut along the center line. The following will use Figures 1 to 6 to illustrate the specific structures of the zipper stopper 100 according to the embodiment of the present invention and the zipper 50 installed with the zipper stopper 100, but the present invention is not limited thereto and can be adjusted according to requirements.

[0060] Please refer to Figure 1 and Figure 2, in this embodiment, the zipper 50 includes a zipper chain 52, a slider 54, and a zipper stopper 100. The zipper chain 52 includes a pair of zipper tapes 52a extending along the length direction L, and a plurality of teeth 52b arranged side by side along the length direction L on the zipper tapes 52a. The slider 54 is mounted on the zipper chain 52 and slides on the zipper chain 52 to open or close the teeth 52b of the pair of zipper tapes 52a. The zipper stopper 100 is mounted at the end of the zipper chain 52. Thus, when the slider 54 slides on the zipper chain 52 in a direction away from the zipper stopper 100 (e.g., Figure 1 the upper side), the plurality of teeth 52b on the pair of zipper tapes 52a engage with each other to close the zipper chain 52 (e.g., Figure 1 the lower side portion), and when the slider 54 slides on the zipper chain 52 in a direction close to the zipper stopper 100 (e.g., Figure 1 the lower side), the plurality of teeth 52b on the pair of zipper tapes 52a are separated from each other to open the zipper chain 52 (e.g., Figure 1 the upper side portion). Further, when at least a part of the zipper stopper 100 enters the tooth channel 54a of the slider 54 (i.e., Figure 2 the state shown), the slider 54 stops sliding further in that direction with the zipper stopper 100 as a stopping point. Here, taking the example where the zipper stopper 100 is mounted at one end (e.g., Figure 1 the lower side) of the length direction L of the zipper chain 52 for illustration. However, the specific structure of the zipper 50 of the present utility model is not limited and can be adjusted according to requirements.

[0061] Specifically, in this embodiment, as Figures 3 to 5 shown, the zipper stopper 100 is adapted to be mounted at the end of the zipper chain 52 and includes a main body portion 110, a stopper portion 120, an inclined portion 130, and a thick portion 140. The main body portion 110 is mounted on a pair of zipper tapes 52a of the zipper chain 52 (e.g., to join the two at one end on one side in the length direction L). The stopper portion 120 is located on one side (e.g., Figure 4 the left-right direction in Figure 4 the left side) of the main body portion 110 in the width direction W (e.g., Figure 4 the front end in Figure 4 the front side) and extends from the first end E1 of the main body portion 110 in the length direction L (e.g., Figure 4 the middle in Figure 4 the front end) of the main body portion 110 towards the first side S1 in the length direction L (Figure 4 extends in a recess on the front side (e.g., the right side in Figure 4 ), and is located on the other side in the width direction W of the main body portion 110 (e.g., Figure 4 the front end in Figure 4 ), and extends from the first end E1 of the main body portion 110 (e.g.,

[0062] As can be seen from this, in the present embodiment, as Figures 3 to 5 shown, the main body portion 110, the stopper portion 120, the inclined portion 130, and the thick portion 140 refer to different parts of the zipper stopper 100. That is, the main body portion 110, the stopper portion 120, the inclined portion 130, and the thick portion 140 are provided integrally, and the zipper stopper 100 including the main body portion 110, the stopper portion 120, the inclined portion 130, and the thick portion 140 is integrally formed through processes such as injection molding. And, the zipper stopper 100 is installed on the zipper chain 52 in such a way that a pair of zipper tapes 52a are joined by the main body portion 110 (as Figure 3 shown), so that, as Figure 1 shown, the pair of zipper tapes 52a of the zipper chain 52 do not separate from the position corresponding to the zipper stopper 100 during the sliding of the slider 54. Among them, the stopper portion 120, the inclined portion 130, and the thick portion 140 are arranged side by side in the width direction W from one side (e.g., Figure 4 the left side in Figure 4 ), to the other side (e.g., Figure 4 the right side in Figure 4 ), and each extends from the first end E1 of the main body portion 110 (e.g.,

[0063] Furthermore, in the present embodiment, as Figures 3 to 5 shown, the inclined portion 130 has an inclined surface 132 that is inclined upward with the thickness gradually increasing from the first side S1 (e.g., Figure 4 the front side in Figure 5 ), the right side in Figure 4 ), toward the second side S2 opposite to the first side S1 (e.g., Figure 5 the rear side in Figure 4 the front side in Figure 5The thickness T1 of the end portion 142 on the right side (in []) is greater than the thickness T2 of the end portion 134 on the first side S1 of the inclined portion 130 in the longitudinal direction L. That is, compared with the stopper portion 120 and the thick portion 140, the inclined portion 130 has an inclined surface 132 that slopes upward from the first side S1 ( Figure 4 the front side in [], Figure 5 the right side in []) toward the second side S2 (for example Figure 4 the rear side in [], Figure 5 the left side in []), so that a recessed area R is formed on the first side S1 ( Figure 4 the front side in [], Figure 5 the right side in []) of the end portion 134 of the inclined portion 130 (as Figure 2 shown in [] and Figure 5 ). And the end portion 142 of the thick portion 140 is thicker than the end portion 134 of the recessed area R formed by the inclined portion 130 (as described later), and a reinforcing structure is formed on the side of the recessed space S (as Figure 3 shown in []).

[0064] With the above arrangement, in this embodiment, the zipper stopper 100 includes a main body portion 110, a stopper portion 120, an inclined portion 130, and a thick portion 140, wherein the inclined portion 130 has an inclined surface 132 that slopes upward from the first side S1 ( Figure 4 the front side in [], Figure 5 the right side in []) toward the second side S2 (for example Figure 4 the rear side in [], Figure 5 the left side in []), and the thickness T1 of the end portion 142 of the thick portion 140 on the first side S1 ( Figure 4 the front side in [], Figure 5 the right side in []) is greater than the thickness T2 of the end portion 134 of the inclined portion 130 on the first side S1 ( Figure 4 the front side in [], Figure 5 the right side in []). Thus, when the slider 54 slides on the zipper chain 52 until at least a part of the zipper stopper 100 enters the tooth channel 54a (as Figure 2 shown in []), the locking claw 54b provided inside the slider 54 enters the recessed area R formed by the inclined surface 132 of the inclined portion 130 or moves upward along the inclined surface 132, so that the locking claw 54b does not damage the zipper stopper 100. And a thick thick portion 140 is also provided on the side of the end portion 134 of the inclined portion 130 where the recessed area R is formed, thereby further enhancing the structural strength of the zipper stopper 100. Accordingly, the zipper stopper 100 and the zipper 50 can avoid damage and cracking of the zipper stopper 100 and enhance the structural strength.

[0065] Furthermore, in this embodiment, asFigure 3 As shown in the figure, each of a pair of zipper tapes 52a includes a core wire 52c provided on the inner edge, and the stopper portion 120 and the thick portion 140 respectively cover the core wires 52c of the pair of zipper tapes 52a. That is to say, when the zipper stopper 100 is integrally formed on the pair of zipper tapes 52a through processes such as injection molding, etc., the pair of zipper tapes 52a are pre-positioned with the core wires 52c on the inner edges separated from each other by a gap, and the zipper stopper 100 is installed on the pair of zipper tapes 52a through processes such as injection molding, etc. In this case, the main body portion 110 engages the two across the pair of zipper tapes 52A in the width direction W, the stopper portion 120 and the thick portion 140 located on the opposite sides in the width direction W are substantially located on the core wires 52c, and the inclined portion 130 located in the middle in the width direction W is substantially located in the gap between the core wires 52c. Thus, the zipper stopper 100 has the thick stopper portion 120 and the thick portion 140 provided on the core wires 52c protruding outward from the surface of the zipper tape 52a, which can improve the engagement strength of the zipper stopper 100 on the zipper tape 52a.

[0066] Furthermore, in this embodiment, as Figure 3 and Figure 5 shown, the zipper stopper 100 is installed on the opposite side surfaces of the zipper tape 52a in the thickness direction T. That is to say, when the zipper stopper 100 is integrally formed on the pair of zipper tapes 52a through processes such as injection molding, etc., the zipper stopper 100 is provided on the zipper tape 52a in such a way that the zipper tape 52a passes through the middle in the thickness direction T of the zipper stopper 100 (as shown in the cross-section of Figure 6 ), so that the side where the inclined surface 132 is formed of the zipper stopper 100 (for example, the upper side in Figure 3 ) is located on one side surface of the zipper tape 52a in the thickness direction T (for example, the upper side surface in Figure 5 ), and the other side of the zipper stopper 100 where the inclined surface 132 is not formed (for example, the lower side in Figure 3 ) is located on the other side surface of the zipper tape 52a in the thickness direction T (for example, the lower side surface in Figure 5 ). Thus, the zipper stopper 100 can be stably installed on the zipper tape 52a. However, the present utility model does not limit the setting manner of the zipper stopper 100 on the zipper tape 52a, and it can be adjusted according to requirements.

[0067] Furthermore, in this embodiment, as Figure 3 and Figure 5 shown, the inclined surface 132 is formed on one side of the inclined portion 130 in the thickness direction T (for example Figure 3 and Figure 5above side in). Specifically, the zipper stopper 100 has a flush lower surface 102. The thickness T2 of the end portion 134 on the first side S1 in the length direction L ( Figure 5 right side in) of the inclined portion 130 refers to the dimension in the thickness direction T from the lower surface 102 of the zipper stopper 100 to the upper surface of the inclined portion 130. The thickness T1 of the end portion 142 on the first side S1 in the length direction L ( Figure 5 right side in) of the thick portion 140 refers to the dimension in the thickness direction T from the lower surface 102 of the zipper stopper 100 to the upper surface of the thick portion 140. Thus, the end portion 142 of the thick portion 140 with a large thickness T1 is located more above in the thickness direction T than the end portion 134 of the inclined portion 130 with a small thickness T2, so that the structural strength of the zipper stopper 100 between the inclined portion 130 and the thick portion 140 can be improved. However, the present utility model does not limit whether the lower surface 102 of the zipper stopper 100 is flush, and it can be adjusted according to requirements.

[0068] Furthermore, in this embodiment, as Figure 3 shown in Figure 5 the thick portion 140 on the first side S1 in the length direction L ( Figure 5 right side in), the thickness T1 of the end portion 142 is smaller than the thickness of other portions of the thick portion 140. That is to say, the portion E1 near the first end of the main body portion 110 of the thick portion 140 has a thickness T3, and the thickness of the thick portion 140 gradually decreases from the portion (thickness T3) near the first end E1 of the main body portion 110 to the end portion 142 (thickness T1). Thus, the end portion 142 of the thick portion 140, for example, is chamfered on the side corresponding to the inclined surface 132 ( Figure 5 above side in) and has a thickness T1 smaller than the thickness of other portions (for example, thickness T3). Preferably, the thickness T4 of the stopper portion 120 and the thickness T5 of the main body portion 110 are equivalent to the thickness T3 of other portions of the thick portion 140. That is to say, the zipper stopper 100 has a substantially flush upper surface 104, and only the thickness of the inclined surface 132 of the inclined portion 130 and the end portion 142 of the thick portion 140 becomes smaller, and a recessed area R and the aforementioned chamfer are formed on the upper surface 104 of the zipper stopper 100.

[0069] As an example, as Figure 3 shown in Figure 5When the thickness T4 of the stopper portion 120 and the thickness T5 of the main body portion 110 shown are 2.6 mm, the thickness T1' of the end portion 142 of the thick portion 140 on the first side S1 on the core wire 52c is 0.51 mm, and the thickness T4' of the end portion 122 of the stopper portion 120 on the first side S1 on the core wire 52c (equivalent to the thickness of other portions of the thick portion 140 on the core wire 52c) is 0.9 mm. Thus, the end portion 142 of the thick portion 140 is thicker than the end portion 134 of the recessed area R formed by the inclined portion 130, but is smaller than the thickness of the end portion 122 of the stopper portion 120 (equivalent to the thickness of other portions of the thick portion 140) to form a chamfer. Thus, the zipper stopper 100 forms an inclined surface 132 only at the portion corresponding to the locking claw 54b (the first side S1 in the length direction L of the inclined portion 130 and the upper side in the thickness direction T), and forms a chamfer at the portion adjacent to the inclined surface 132 (the end portion 142 of the thick portion 140 on the first side S1), while other portions are maintained substantially flush, so that the zipper stopper 100 can take into account practicality, aesthetics, and structural strength. However, the present utility model does not limit the relative thicknesses of the above-mentioned portions, and they can be adjusted according to requirements.

[0070] In addition, in the present embodiment, as Figure 4 shown in Figure 5 the length L1 of the stopper portion 120 in the length direction L (i.e., the dimension from the first end E1 of the main body portion 110 to the end portion 122 of the stopper portion 120 on the first side S1) is greater than the length L2 of the thick portion 140 in the length direction L (i.e., the dimension from the first end E1 of the main body portion 110 to the end portion 142 of the thick portion 140 on the first side S1), and the length L3 of the inclined portion 130 in the length direction L (i.e., the dimension from the first end E1 of the main body portion 110 to the end portion 134 of the inclined portion 130 on the first side S1) is between the length L1 of the stopper portion 120 and the length L2 of the thick portion 140 and has an inclined surface 132 to form a recessed area R. And, the end portion 136a of the inclined portion 130 connecting the stopper portion 120 is closer to the first side S1 in the length direction L than the end portion 136b of the inclined portion 130 connecting the thick portion 140 ( Figure 4 the front side in Figure 5 ), the right side in Figure 4 ). That is, when based on the first end E1 of the main body portion 110 (for example, Figures 3 to 5 the front end in Figure 4extends forward (front side in []) so that the end portion 134 of the inclined portion 130 has a side edge 132a inclined in the width direction W.

[0071] With the above arrangement, in this embodiment, as Figures 3 to 5 shown, the front end portion 106 of the zipper stopper 100 corresponding to the first side S1 is not flush due to the different lengths of the end portion 122 of the stopper portion 120, the end portion 134 of the inclined portion 130, and the end portion 142 of the thick portion 140. The stopper portion 120 is a portion that enters the tooth channel 54a of the slider 54 of the zipper stopper 100 and stops the sliding of the slider 54 (as Figure 2 shown), the thick portion 140 is a portion for reinforcing the recessed area R of the inclined portion 130, and the inclined portion 130 can connect the stopper portion 120 and the thick portion 140 with different lengths in a manner inclined in the width direction W and has good structural strength. In contrast, the rear end portion 108 of the zipper stopper 100 corresponding to the second side S2 (i.e., the second end E2 of the main body portion 110 opposite to the first end E1) is flush. In this way, the zipper stopper 100 forms the stopper portion 120, the inclined portion 130, and the thick portion 140 with different lengths only at the portion corresponding to the slider 54 (front end portion 106), while other portions are maintained substantially flush, so that the zipper stopper 100 can take into account practicality, aesthetics, and structural strength. However, the present utility model does not limit the relative lengths of the above-mentioned portions, nor does it limit whether the rear end portion 108 of the zipper stopper 100 is flush, which can be adjusted according to requirements.

[0072] In addition, in this embodiment, as Figures 3 to 5 shown, the inclined surface 132 has a side edge located on the first side S1 in the length direction L ( Figure 4 front side in [], Figure 5 right side in []) and connecting the stopper portion 120 and the thick portion 140 (i.e., the side edge 132a inclined in the width direction W mentioned above), and the lowest point 132b of the inclined surface 132 closest to the bottom in the thickness direction T passes through the side edge 132a (as Figure 3 shown). That is to say, the inclined surface 132 is open toward the first side S1 in the length direction L ( Figure 4 front side in []). In this way, when the slider 54 slides on the zipper chain 52 until at least a part of the zipper stopper 100 enters the tooth channel 54a (as Figure 2 shown), even if the size of the locking claw 54b provided inside the slider 54 is larger than the size of the recessed area R and contacts the inclined surface 132, the locking claw 54b can move upward along the inclined surface 132 from the side edge 132a having the lowest point 132b of the inclined surface 132 open toward the first side S1, so that the locking claw 54b will not cause damage to the zipper stopper 100.

[0073] Furthermore, in this embodiment, as Figures 3 to 5 shown, the inclined surface 132 of the inclined portion 130 extends more towards the thick portion 140 than the center line C in the width direction W. Among them, as Figure 3 shown, the distance d1 from the lowest point 132b along the side edge 132a to the thick portion 140 is greater than the distance d2 from the lowest point 132b along the side edge 132a to the stopper portion 120, and the inclination from the lowest point 132b along the side edge 132a to the thick portion 140 (such as Figure 3 the angle θ1 shown) is smaller than the inclination from the lowest point 132b along the side edge 132a to the stopper portion 120 (such as Figure 3 the angle θ2 shown). That is to say, based on the center line C, the proportion of the inclined surface 132 of the inclined portion 130 on the side closer to the thick portion 140 ( Figure 3 the left side) is greater than the proportion of the inclined surface 132 on the side closer to the stopper portion 120 ( Figure 3 the right side). In this way, when the locking claw 54b of the slider 54 is disposed in a biased manner, the locking claw 54b can also move upward along the inclined surface 132 disposed in a biased manner, so that the locking claw 54b will not damage the zipper stopper 100. And, the inclination of the portion between the inclined portion 130 and the thick portion 140 is low (the slope is gentle), so that the structural strength of the portion between the inclined portion 130 and the thick portion 140 can be improved.

[0074] As an example, as Figure 6 shown, in the cross-section of the zipper stopper 100 cut along the center line C, the height H1 of the inclined surface 132 of the inclined portion 130 in the thickness direction T is approximately 1.1 millimeters (millimeter, mm) and the length L4 in the length direction L is approximately 1.025 millimeters. That is to say, at the portion of the approximate center line C, the height H1 of the inclined surface 132 of the inclined portion 130 in the thickness direction T is approximately equal to the length L4 in the length direction L. Based on this, at the portion closer to the thick portion 140, the thickness of the inclined surface 132 gradually increases, so that the height H1 of the inclined surface 132 in the thickness direction T gradually becomes smaller (the height H1 of the inclined surface 132 in the thickness direction T is less than the length L4 in the length direction L) and the inclination gradually decreases and becomes flat. In this way, the structural strength of the portion between the inclined portion 130 and the thick portion 140 can be improved. However, the present utility model does not limit the arrangement manner of the inclined surface 132 of the inclined portion 130, which can be adjusted according to requirements.

[0075] In summary, in the stopper for a zipper and the zipper of the present utility model, the stopper for a zipper includes a main body portion, a stopper portion, an inclined portion, and a thick portion. The inclined portion has an inclined surface that slopes upward from the first side toward the second side in the length direction, and the thickness of the thick portion at the end on the first side is greater than the thickness of the inclined portion at the end on the first side. Thus, when the slider slides on the zipper chain until at least a part of the stopper for a zipper enters the tooth channel, the locking claw provided inside the slider enters the recessed area formed by the inclined surface of the inclined portion or moves upward along the inclined surface, without causing damage to the stopper for a zipper. Also, a thick portion with a relatively large thickness is provided on the side of the end of the inclined portion where the recessed area is formed, further enhancing the structural strength of the stopper for a zipper. Preferably, the thickness of the end of the thick portion on the first side in the length direction is less than the thickness of other parts of the thick portion, so that the thick portion does not interfere with the tooth channel. Accordingly, the stopper for a zipper and the zipper of the present utility model can avoid damage and cracking of the stopper for a zipper and enhance the structural strength.

[0076] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them. Although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features. However, such 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 utility model.
