[0039] The following describes non-limiting embodiments and features of the present invention with reference to the accompanying drawings. A person skilled in the art will be able to combine the various embodiments and / or features without excessive explanation and will also understand the complementary effects brought about by their combination. In principle, repeated descriptions between the embodiments will be omitted. The accompanying drawings are primarily for the purpose of describing the invention and are simplified for the convenience of drawing. Each feature is not only valid for the zipper disclosed in this specification but should be understood as a general feature that is also applicable to various other zippers not disclosed in this specification.

[0040] In this specification, the front-to-back direction, the left-to-right direction, and the top-to-bottom direction correspond to the length direction, width direction, and thickness direction of the zipper, respectively. In this specification and the claims, terms such as 1, 2, 3, and 4 are used to distinguish elements with the same name. For many elements in this specification, an identifier such as "m" is assigned to "1st", and an identifier such as "n" is assigned to "2nd". However, in order to avoid lengthy descriptions, these terms (especially 1st and 2nd) are intentionally omitted in many places. In addition, the definition of direction can be redefined based on the description of this specification. For example, the front-to-back direction can be defined as a direction that is consistent with the moving direction of the slider.

[0041] Reference Figures 1 to 6 The structure and function of the zipper 1 are described below. The zipper 1 includes zipper tapes 2m and 2n, a slider 8, and a detachable stopper 10. The zipper tapes 2m and 2n are flexible, elongated members. The zipper tapes 2m and 2n include zipper tapes 3m and 3n, waterproof films 4m and 4n attached to the upper surfaces of the zipper tapes 3m and 3n, spiral members 6m and 6n positioned on the lower surfaces of the zipper tapes 3m and 3n, and flexible core cords 7m and 7n at least partially inserted through the interior of the spiral members 6m and 6n. The slider 8 advances to engage the spiral members 6m and 6n, and retracts to release the engagement of the spiral members 6m and 6n.

[0042] The zipper tapes 3m and 3n are thin layers of woven and / or braided fabric. The waterproof films 4m and 4n are typically made of a polymer material such as polyurethane. The waterproof films 4m and 4n are attached to the upper surfaces of the zipper tapes 3m and 3n, respectively (e.g., with an adhesive or by direct welding), thereby imparting waterproof properties to the zipper tape and, consequently, the zipper.

[0043] The waterproof films 4m and 4n preferably have a thickness of 5 μm or more, 10 μm or more, 15 μm or more, 20 μm or more, or 25 μm or more. The waterproof films 4m and 4n preferably have a thickness of 50 μm or less, 40 μm or less, or 30 μm or less. By forming the waterproof films 4m and 4n to the thickness described above, the reduction in the softness of the zipper tape caused by the lamination of the waterproof film can be suppressed, and sufficient cushioning (elasticity) of the waterproof film can be ensured. When an adhesive is used to laminarize the waterproof film, an adhesive layer can be formed between the waterproof film and the zipper tape. The thickness of the adhesive layer (for example, the maximum thickness) is preferably in the range of 125 μm to 135 μm. By sufficiently ensuring the layer thickness of the adhesive, the cushioning (elasticity) can also be increased.

[0044] In some cases, the width of the waterproof film is (typically slightly) greater than the width of the zipper tape. As a result, the waterproof films 4m, 4n can have opposing side edges 41m, 41n located closer to the centerline CL of the zipper 1 than the opposing side edges of the zipper tapes 3m, 3n, in the width direction of the zipper 1. This can facilitate a narrower spacing between the opposing side edges 41m, 41n or promote contact between the opposing side edges 41m, 41n. Additionally or alternatively, the waterproof films 4m, 4n can have opposing side edges 42m, 42n located further from the centerline CL of the zipper 1 than the opposing side edges 32m, 32n of the zipper tapes 3m, 3n, thereby expanding the waterproof range in the width direction of the zipper 1.

[0045] The spiral members 6m and 6n are engaging members for the zipper chain tapes 2m and 2n to engage with each other. They engage with each other by the forward movement of the slider 8 and are released by the backward movement of the slider 8. The spiral members 6m and 6n are arranged on the opposite side edges 35m and 35n (the first side edge and the second side edge) of the zipper tapes 3m and 3n. The spiral members 6m and 6n are spiral bodies formed by spirally winding a monofilament and including a plurality of engaging heads formed at a predetermined interval. One turn (spiral unit) of the spiral body forms one chain tooth (zipper chain tooth). As shown in FIG. Figure 6 As shown, each sprocket has an upper leg 61, a lower leg 62, an engaging head 63, and a reversing portion 64. The engaging head 63 is formed from a monofilament with a wide width in the front-to-back direction. The engaging head 63 of one of the spiral members 6m and 6n enters between adjacent engaging heads 63 of the other, and this situation occurs continuously in the front-to-back direction. As a result, the spiral members 6m and 6n engage with each other, and then the zipper stringers 2m and 2n engage with each other, thereby closing the zipper 1.

[0046] In some cases, the spiral members 6m and 6n are sewn to the fastener tapes 3m and 3n using double lockstitching. In this case, tiny recesses are formed on the upper surfaces of the fastener tapes 3m and 3n, caused by the stitching pulling the constituent yarns (e.g., weft yarns) of the fastener tapes 3m and 3n downward. Advantageously, the waterproof films 4m and 4n fill these tiny recesses with the adhesive used to bond the fastener tapes 3m and 3n, thereby improving the solidity of the fastener stringers 2m and 2n.

[0047] As described above, the core cords 7m and 7n are at least partially positioned within the spiral members 6m and 6n, thereby reinforcing the spiral members 6m and 6n. The core cords 7m and 7n extend in the front-to-back direction within the spiral members 6m and 6n, thereby being sandwiched between the rows of upper legs 61 and lower legs 62 arranged in the front-to-back direction. The core cords 7m and 7n are typically braided cords, exhibiting high softness and bulk. Preferably, the core cords 7m and 7n are sewn to the zipper tapes 3m and 3n together with the spiral members 6m and 6n using double-lock stitching.

[0048] The slider 8 is made of metal or resin and comprises an upper wing plate 81, a lower wing plate 82, a connecting post 83 connecting the upper wing plate 81 and the lower wing plate 82 at their front ends, left and right lower flanges 84m and 84n rising upward from the left and right edges of the lower wing plate 82, and left and right upper flanges 85m and 85n rising downward from the left and right edges of the upper wing plate 81 (see FIG. Figure 7A 、 7B The upper wing plate 81 has a pull-tab mounting portion 88 for mounting a pull-tab 89. The pull-tab mounting portion 88 contains a locking member that can engage with the spiral members 6m and 6n via a claw hole described later that passes through the upper wing plate 81. Figure 7A and 7B The automatic slider shown can also be used as a semi-automatic slider, a free slider, etc.

[0049] The spiral members 6m and 6n are arranged on the lower surface side of the fastener tapes 3m and 3n (on the side opposite to their upper surfaces), so that the lower flanges 84m and 84n are higher (in the vertical direction) than the upper flanges 85m and 85n. Furthermore, the lower flange 84m and the upper flange 85m are opposed to each other in the vertical direction, forming a slit for inserting the tape portion of the fastener tape 2m (including the laminated portion of the fastener tape 3m and the waterproof film 4m) therebetween. Similarly, the lower flange 84n and the upper flange 85n are opposed to each other in the vertical direction, forming a slit for inserting the tape portion of the fastener tape 2n (including the laminated portion of the fastener tape 3n and the waterproof film 4n) therebetween.

[0050] A dividing strip 86 protruding downward is provided on the upper wing plate 81. The width of the dividing strip 86 is less than 1 / 2 of the maximum width of the connecting column, preferably less than 1 / 3. In some embodiments, the dividing strip 86 is arranged in the width direction of the zipper 1 at a position close to one of the left and right zipper tapes 2m and 2n in the engaged state (in simple terms, close to the zipper tape 2n), and has a larger contact area with the film side edge 4m1 of the waterproof film 4m than with the film side edge 4n1 of the waterproof film 4n. In other words, by selectively pressurizing the film side edge 4n1 of the waterproof film 4n downward using the dividing strip 86, the sliding of the slider 8 can be made lighter (in other words, the force required for the sliding of the slider 8 can be reduced) compared to the case where both the film side edges 4m1 and 4n1 of the waterproof films 4m and 4n are equally pressurized downward.

[0051] The separator strip 86 has a pressure surface 86j that applies pressure to at least the film side edge 4n1 of the waterproof film 4n. While it is not ruled out that the film side edge 4m1 and the film side edge 4n1 may be pressed downward by the separator strip 86's pressure surface 86j, the degree of pressure is less. The film side edges 4m1 and 4n1 of the waterproof films 4m and 4n protrude toward the centerline CL of the zipper 1 beyond the zipper tapes 3m and 3n, and a gap exists directly below them between the zipper tapes 3m and 3n. Furthermore, the film side edges 4m1 and 4n1 of the waterproof films 4m and 4n are adjacent in the width direction of the zipper 1 (or, in other terms, are located on both sides of the centerline CL of the zipper 1), and in some cases, a continuous or intermittent gap exists between them. This gap can increase or decrease depending on the relative orientation of the zipper tapes 3m and 3n.

[0052] The partition bar 86 has a first wall surface 86m and a second wall surface 86n on both sides of the pressure surface 86j, which define the width of the partition bar 86 itself. The first wall surface 86m and the second wall surface 86n are preferably perpendicular to the width direction of the slider 8, but are not necessarily limited to this. The first wall surface 86m is arranged closer to the center plane PS of the slider 8 than the second wall surface 86n. In a certain case, such as Figure 7B As shown, the first wall surface 86m is located at a position on the outside of the zipper tape 3n than the film side edge 4n1 of the waterproof film 4n. In another case, the first wall surface 86m is located at a position on the inside of the zipper tape 3n than the film side edge 4n1 of the waterproof film 4n. In yet another case, the first wall surface 86m is located directly above the film side edge 4n1 of the waterproof film 4n, and both are arranged in the same plane. In addition, the outside of the tape refers to the direction from the position inside the tape surface of the zipper tape (for example, inside the upper surface) toward the position outside the tape surface, and the inside of the tape refers to the direction toward the opposite side. In addition, the center plane PS of the slider 8 can be replaced by the center line of the slider 8. The center line of the slider 8 is typically included in the center line of the zipper 1.

[0053] The distance between the first wall surface 86m of the partition bar 86 and the film side edge 4n1 of the waterproof film 4n in the width direction of the slide fastener 1 can be within the thickness range of the waterproof film 4n (eg, 20 μm to 100 μm).

[0054] The partition bar 86 extends rearward from the rear end of the connecting column 83 (see Figure 7A ), optionally including a portion extending along one side of the connecting column 83 (the left side in the illustration, or the rod member 11 side when compared to the seat member 12). The dividing bar 86 can be divided into a rear portion 86a sandwiched between the left and right upper flanges 85m and 85n, and a front portion 86b located forward of the rear portion 86a. The rear end of the rear portion 86a of the dividing bar 86 is located forward of the rear end of the upper wing plate 81.

[0055] Preferably, the width of the gap between the zipper tapes 3m, 3n is within the range of 0.05mm to 0.6mm. Preferably, the width of the separator strip 86 is within the range of 0.2mm to 0.6mm. Optionally, the height of the upper flanges 85m, 85n is within the range of 0.2mm to 0.6mm.

[0056] The film side edges 4m1 and 4n1 of the waterproof films 4m and 4n can be supported by support portions 9, which are portions of the adhesive used to bond the waterproof films 4m and 4n to the fastener tapes 3m and 3n. In this case, when the film side edges 4m1 and 4n1 deform, the support portions 9 also deform, and the flexibility of the film side edge 4n1 is reduced by the support portions 9. In such cases, as described above, it is particularly advantageous for the separator strip 86 to selectively pressurize one of the film side edges 4m1 and 4n1.

[0057] In some cases, the adhesive used to adhere the waterproof films 4m and 4n to the fastener tapes 3m and 3n may penetrate from the upper surface of the fastener tapes 3m and 3n into the structure thereof. Figure 7B The dotted line L9 schematically represents the boundary between the upper portion of the fastener tapes 3m and 3n that is impregnated with adhesive and the lower portion of the fastener tapes 3m and 3n that is not impregnated with adhesive. Of course, it should be noted that the boundary is not formed on a common plane, but may be formed unevenly.

[0058] A claw hole 87 is formed on the upper wing plate 81 adjacent to the partition bar 86. The claw hole 87 is formed to pass through the upper wing plate 81 and at least partially accommodates the claw end of the locking member (not shown). The locking member has a pull-tab mounting portion 88 for mounting the pull-tab of the upper wing plate 81. The pull-tab mounting portion 88 has a pivotable locking member (not shown) that is biased into a locked state by a biasing member. The locking member is typically an elastic leaf spring. When a person lifts the pull-tab, the mounting shaft of the pull-tab presses the locking member and lifts the locking claw of the locking member, releasing the engagement with the spiral members 6m and 6n.

[0059] The claw hole 87 is located near the junction of the rear portion 86a and the front portion 86b of the dividing strip 86. Typically, it is located closer to the rear portion 86a than the junction. The claw hole 87 is located directly above the spiral member 6m, allowing the locking member to enter. The waterproof film 4m protrudes from the zipper tape 3m toward the center plane PS of the slider 8, so it is possible for the waterproof film 4m to be located directly below the claw hole 87. The locking member is made of metal and has a tapered claw at the bottom, which can reduce the impact of interference with the waterproof film 4m.

[0060] The zipper stringers 2m and 2n further include reinforcement members 5m and 5n, which are bonded to the lower surface of the portion of the zipper string 3m and 3n located rearward of the spiral member 6m and 6n (e.g., by partial melting) in a manner that covers the core cord 7m and 7n with a width less than the entire width of the zipper string 3m and 3n. The reinforcement members 5m and 5n are harder than the waterproof film 4m and 4n, and this can be verified, for example, by a Vickers hardness test.

[0061] In some cases, the reinforcement members 5m and 5n are thicker than the waterproof films 4m and 4n. Even with this feature, when the half parts (rod member 11 and seat member 12) of the stopper 10 are pressed and fixed to the laminated parts 71 and 72 described later, the hardness of the reinforcement members can be compensated by the softness of the waterproof film, and cracks are unlikely to occur in the reinforcement members.

[0062] The reinforcements 5m and 5n are selectively attached to the lower surface of the zipper tapes 3m and 3n and (unlike the usual method) are not placed on their upper surface. Therefore, the reinforcements 5m and 5n are formed thicker than usual and, in typical cases, can include a portion with a thickness of more than 160 μm. As a result, cracks and the like are easily generated in the reinforcements 5m and 5n. However, as described above, the hardness of the reinforcements is compensated by the softness of the waterproof film, resulting in the suppression of cracks and the like in the reinforcements. In addition, no reinforcements are attached to the upper surface of the zipper tapes 3m and 3n, but waterproof films 4m and 4n are attached, thereby ensuring sufficient thickness to press and secure the half-accessories of the stopper 10.

[0063] In some cases, the reinforcements 5m and 5n are knurled, with downwardly protruding ribs formed on their lower surfaces in a predetermined pattern corresponding to the material's shape. This creates a non-smooth, non-slip surface on the lower surfaces of the reinforcements 5m and 5n, improving the operability of the stopper 10 when opening and closing. When the reinforcements 5m and 5n are knurled, the reinforcements 5m and 5n have the greatest thickness at the ribs and the smallest thickness at the base layer, where the ribs are not provided.

[0064] In some cases, the reinforcements 5m and 5n include at least a film layer and an adhesive layer (e.g., a laminated structure), optionally with at least one intermediate layer interposed therebetween. If the reinforcements 5m and 5n are multi-layered, their thickness increases, making them more susceptible to hardening (and, consequently, cracking). Regarding this point, in the present disclosure, as described above, the hardness of the reinforcements is compensated by the softness of the waterproof film, thereby suppressing cracking in the reinforcements.

[0065] The film layer of the reinforcement members 5m and 5n can be a film of nylon 6, or an elastomeric film of a polyamide, polyester, polyolefin or polyurethane system. The adhesive layer of the reinforcement members 5m and 5n can be a thermoplastic adhesive, preferably a polyester thermoplastic adhesive. The middle layer is an anchor coating agent such as a two-liquid curing type adhesive composed of a copolymer of a polyol as a main agent and a diisocyanate as a curing agent, which has good adhesion to the film layer and the adhesive layer. When the reinforcement members 5m and 5n are attached to the zipper tapes 3m and 3n, the adhesive layer can penetrate into the tissue of the zipper tapes 3m and 3n. As a result, the free movement of the constituent yarns of the zipper tapes 3m and 3n is hindered (this is an effect consistent with the purpose of use of the reinforcement members 5m and 5n).

[0066] When the reinforcement members 5m and 5n have the three-layer structure described above, the thickness of the reinforcement members 5m and 5n can be measured with the bottom surface of the fastener tapes 3m and 3n as the reference plane. In other words, the thickness of the adhesive layer that has penetrated the structure of the fastener tapes 3m and 3n is excluded from the thickness of the reinforcement members 5m and 5n. The thickness of the film layer (e.g., maximum thickness) can be within the range of 200 μm to 300 μm.

[0067] The reinforcements 5m and 5n can be narrower than the zipper tapes 3m and 3n. As a result, the lower surfaces of the zipper tapes 3m and 3n are not covered by the reinforcements 5m and 5n but are exposed at their side edges 36m and 36n (the 3rd and 4th side edges) that are further away from the center line CL of the zipper 1. As a result, the reinforcements 5m and 5n are more difficult to peel off from the zipper tapes 3m and 3n. Depending on the circumstances, the leakage of the adhesive used to attach the reinforcements 5m and 5n can be suppressed. That is, even if the adhesive of the lower layer of the film layer leaks out laterally than the film layer, it only penetrates into the tissue of the zipper tapes 3m and 3n. In addition, the side edge 36m has a width defined between the imaginary lines L1 and L3. Similarly, the side edge 36n has a width defined between the imaginary lines L2 and L4.

[0068] The detachable stopper 10 includes a rod member 11 and a seat member 12, both of which are made of metal. The rod member 11 and the seat member 12 are respectively mounted on the zipper tapes 3m and 3n. By engaging the rod member 11 and the seat member 12, the engaging start state of the left and right zipper tapes 2m and 2n can be constructed. The rod member 11 is arranged adjacent to the spiral member 6m at the rear end of the spiral member 6m, and the seat member 12 is arranged adjacent to the spiral member 6n at the rear end of the spiral member 6n. Typically, the rod member 11 has a rear end portion that decreases in width toward the rear, thereby facilitating smooth insertion into the interior of the slider 8 and the slot of the seat member 12. A notch 11j that accommodates the engaging head of the rearmost end of the spiral member 6n can be formed at the front end of the rod member 11.

[0069] In this embodiment, the rod member 11 is pressed and fixed to the first laminated portion 71, which includes the first waterproof film 4m, the first zipper tape 3m, the first core cord 7m, and the first reinforcement 5m (typically, consisting of these components), in a manner that applies pressure to the first waterproof film 4m. Additionally or alternatively, the seat member 12 is pressed and fixed to the second laminated portion 72, which includes the second waterproof film 4n, the second zipper tape 3n, the second core cord 7n, and the second reinforcement 5n (typically, consisting of these components), in a manner that applies pressure to the second waterproof film 4n. The first and second laminated portions include the hard portions of the reinforcements 5m and 5n, respectively, while the other portion includes the softer portions of the waterproof films 4m and 4n. Therefore, by pressing and fixing the half parts of the stopper 10 to the laminated parts 71 and 72 in a manner that pressurizes the waterproof films 4m and 4n, cracks in the reinforcements 5m and 5n can be suppressed, and the stopper 10 can continue to have good operability during long-term use of the zipper 1.

[0070] In some cases, the flexural modulus of the waterproof membranes 4m and 4n is less than 1 / 2 of the flexural modulus of the reinforcements 5m and 5n. The flexural modulus of the waterproof membranes 4m and 4n may be 100 to 1000 (or further 100 to 400) kg / cm2 On the other hand, the bending elastic modulus of the reinforcement members 5m and 5n can be 3000 kg / cm 2 ~9000kg / cm 2 This can further promote the above-mentioned effects. In addition, the bending modulus is based on the bending test of Japanese Industrial Standard JIS K7171.

[0071] The reinforcements 5m and 5n are harder than the waterproof films 4m and 4n, thereby improving the operability of opening and closing the zipper 1 when it is installed on clothing. For example, when the closed zipper 1 or its zipper stringers 2m and 2n are lifted while the zipper 1 is sewn to clothing, the lower end portions of the engaged left and right zipper stringers 2m and 2n (having the reinforcements 5m and 5n) can be transformed from a flat posture to a tapered shape with a width that expands downward (as a result, the lower side of the zipper 1 is recessed). At this time, it is easy for the wearer of the clothing to pinch the reinforcements 5m and 5n with their fingers. For this reason, when the rod member 11 is released from the seat member 12, its operability can be improved. When the above-mentioned knurling process is implemented, the concave and convex parts of the reinforcements 5m and 5n become handles, which can further improve the ease of gripping the lower end portions of the zipper stringers 2m and 2n. For this purpose, the knurled convex portion preferably extends continuously within a certain width range of the reinforcement members 5m, 5n, for example, extending parallel to the left-right direction in the slide fastener 1, or as shown in FIG. Figure 2 As shown in the figure, it extends obliquely (preferably, formed into a mesh shape).

[0072] In some cases, the rod member 11 is secured by compression, accompanied by at least local plastic deformation of the rod member 11. Similarly, the seat member 12 is preferably secured by compression, accompanied by at least local plastic deformation of the seat member 12. This local plastic deformation is the result of mechanical processing such as cutting, pressing, and / or bending performed on a portion of the half of the stopper 10 (typically, the flat plate). Therefore, the specific shape of the resulting pressurized portion is not particularly limited.

[0073] Typically, the rod member 11 has one or more protrusions or one or more curved pieces that serve as pressurizing elements in response to the aforementioned localized plastic deformation. Similarly, the seat member 12 has one or more protrusions or one or more curved pieces that serve as pressurizing elements in response to the aforementioned localized plastic deformation. These pressurizing elements, such as protrusions or curved pieces, apply pressure to the laminated portion (preferably, selectively applying pressure to the waterproof film) or are embedded in the laminated portion (preferably, selectively embedding the waterproof film). This facilitates the secure fixation of the half-part of the stopper 10 relative to the laminated portion. The number of pressurizing elements formed on the rod member 11 is preferably one, but may be two or more. The same applies to the seat member 12. If the waterproof film 4m is pressurized by multiple pressurizing elements on the rod member 11, there is a risk of the waterproof film 4m being stretched between the different pressurized areas, causing it to break. Having a single pressurizing element on the rod member 11 avoids or mitigates this problem. The same applies to the seat member 12. Typically, the number of pressing portions of the rod member 11 is equal to the number of pressing portions of the seat member 12 .

[0074] Reference Figure 4 To explain, the rod member 11 includes an upper plate 21 and a lower plate 22 that sandwich the first laminated portion 71 from above and below, a side plate 23 that connects the upper plate 21 and the lower plate 22, and a flange 24 that protrudes upward from the lower plate 22 and faces the side plate 23 (in the width direction). In some cases, after the first laminated portion 71 is inserted between the upper plate 21 and the lower plate 22, the rod member 11 is plastically deformed by applying pressure so as to wrap around the first laminated portion 71 as the vertical spacing between the upper plate 21 and the lower plate 22 decreases (see Figure 4 The rod member 11 may be mounted solely by the aforementioned local plastic deformation.

[0075] Reference Figure 3 The seat member 12 includes a seat portion 12a and a seat rod 12b. Typically, the seat member 12 is a single component formed by integrally molding the seat rod 12b and seat portion 12a (e.g., by die-casting). However, two components may be used, with the seat rod 12b joined to the seat portion 12a by interlocking or other means. The rod 11 engages and disengages with the seat member 12 in response to insertion and removal of the rod 11 into the slot of the seat portion 12a.

[0076] Similar to rod member 11, seat bar 12b includes an upper plate 31 and a lower plate 32 that sandwich second stacked portion 72 from above and below; a side plate 33 connecting the upper and lower plates 31 and 32; and a flange 34 that protrudes upward from lower plate 32 and faces side plate 33 (in the width direction). Seat portion 12a is capable of plastic deformation similar to rod member 11, but this is not a limitation. Seat member 12 can be attached solely through localized plastic deformation. Since seat bar 12b is connected to seat portion 12a, plastic deformation is not readily achieved.

[0077] The seat portion 12a includes an upper plate 41 and a lower plate 42, which define a slot for inserting and removing the rod member 11 and a belt groove that is spatially connected to the slot. The seat portion 12a includes a side surface 43 that connects the lower surface of the upper plate 41 to the upper surface of the lower plate 42. The upper plate 41 and the lower plate 42 have opposing flanges 44 and 45 that define the belt groove. The width of the slot is defined between the flanges 44 and 45 and the side surface 43. In addition, the portion of the zipper stringer 2m adjacent to the rod member 11 (the laminated portion of the zipper tape 3m, the waterproof film 4m, and the reinforcement 5m) can be inserted and removed from the belt groove.

[0078] The rod member 11 has at least one first pressing portion 13 (see FIG. 1 ) that is plastically deformed so as to pressurize at least the upper surface of the first waterproof film 4m. Figure 1 、 Figure 6 Similarly, the seat member 12 (typically, the seat rod 12b) includes at least one second pressing portion 14 that is plastically deformed so as to pressurize at least the upper surface of the second waterproof film 4n. Figure 6 The illustrated pressurizing portion 13 is a curved piece that is pushed downward from the flat portion and bent by mechanical processing (e.g., using a punch). The pressurizing portion 13 preferably extends in a manner that gradually descends as it extends from its base end connected to the flat portion toward its free end. Furthermore, through the aforementioned mechanical processing, a wall surface 13a is formed on the flat portion corresponding to the free end of the curved piece. The pressurizing portion 14 can be formed using the same method as the pressurizing portion 13 and is omitted from illustration.

[0079] The upper surface of the waterproof film 4m includes a first pressurized area pressurized by the upper plate 21 and a second pressurized area pressurized by the pressurizing portion 13. The upper surface of the waterproof film 4n includes a third pressurized area pressurized by the upper plate 31 and a fourth pressurized area pressurized by the pressurizing portion 14. Preferably, the second pressurized area is surrounded by the first pressurized area, and similarly, the fourth pressurized area is surrounded by the third pressurized area. Thus, even if the waterproof films 4m and 4n are partially broken by the pressurizing portions 13 and 14, the surrounding film material can be used to seal the broken area. The first and third pressurized areas can be located in a plane perpendicular to the vertical direction. The second and fourth pressurized areas can be formed to extend obliquely from the first and third pressurized areas. Typically, the second pressurized region and the fourth pressurized region have smaller areas than the first pressurized region and the third pressurized region, for example, less than 1 / 2 or less than 1 / 3 of the first pressurized region and the third pressurized region.

[0080] When the rod member 11 is inserted into the slot of the seat member 12, the pressurizing portions 13 and 14 are visually distinguishable. When the rod member 11 is inserted into the slot of the seat member 12, the pressurizing portions 13 and 14 are arranged side by side (in the width direction). This allows the stopper 10 to have a symmetrical pattern about the centerline CL of the zipper 1, minimizing the appearance of the stopper 10 from causing discomfort to the user. More preferably, the pressurizing portions 13 and 14 extend elongated in the front-to-back direction, coinciding with the direction in which the rod member 11 and the seat bar 12b extend.

[0081] In some cases, the pressurizing parts 13 and 14 are formed so as not to penetrate the waterproof films 4m and 4n. Thus, it is possible to avoid or suppress the deterioration of the waterproof performance of the zipper 1 due to the pressurizing parts 13 and 14. In another case, the pressurizing parts 13 and 14 are formed so as to penetrate the waterproof films 4m and 4n. Figure 6 In the case shown, the pressurizing portion 13 is embedded in the waterproof film 4m at its free end and penetrates the waterproof film 4m. In this case, it is also expected that the waterproof performance can be fully ensured by the waterproof films 4m and 4n being softer than the reinforcements 5m and 5n.

[0082] In addition, if Figure 6 As can be seen, the waterproof film 4m and the fastener tape 3m are released from the pressure between the upper plate 21 and the lower plate 22 near the tip of the rod member 11, or are slightly displaced upward for other reasons (for example, from a lower plane perpendicular to the vertical direction to an upper plane). This improves the flatness of the surface of the fastener stringer 2m. Similarly, near the tip of the seat bar 12b, the waterproof film 4n and the fastener tape 3n are also slightly displaced upward.

[0083] Reference Figure 7AThe steps for inserting the rod member 11 into the slot SL relative to the seat member 12 are described. First, the user pulls the slider 8 to its rearmost position in advance. At this time, the slider 8 collides with the front surface of the seat portion 12a, and the seat rod 12b is inserted into the slider 8. The user then pinches the rear end of the zipper chain 2n with the thumb and index finger of one hand. The user then pinches the rear end of the zipper chain 2m with the thumb and index finger of the other hand and inserts the rod member 11 into the slot SL through the internal passage of the slider 8. After the rod member 11 is completely inserted into the slot SL, the slider 8 is moved forward, and accordingly, the sprockets (or engaging heads 63) of the left and right spiral members 6m and 6n are alternately engaged. In the present disclosure, the half-accessories of the stopper 10 are all made of metal, and therefore have high mechanical strength, and in particular, they are installed by being pressed and fixed, thereby also having high installation strength. During compression and fastening, the laminated portion, which serves as the attachment point for the half-part, includes not only the reinforcement but also the waterproof film. Therefore, the hardness of the reinforcement is offset by the softness of the waterproof film, resulting in a reduction in cracks in the reinforcement. This ensures that the stopper 10 maintains good operability over the long term use of the zipper 1.

[0084] Figure 8 The schematic diagram shows a state where waterproof films 4m and 4n are bonded to the upper surface of the fastener tape 3m via an adhesive 4g. The adhesive 4g can be a thermosetting adhesive. Figure 9 The schematic diagram shows a zipper tape 3m sandwiched between a waterproof film 4m and a reinforcement member 5m. The reinforcement member 5m comprises a film layer 96, an intermediate layer 97, and an adhesive layer 98 (intermediate layer 97 can be omitted). Adhesive layer 98, unlike adhesive 4g, can be a thermoplastic adhesive. This allows adhesives of different properties, thermoplastic and thermosetting, to penetrate the zipper tape 3m. Since both adhesives are not thermoplastic, the half-assembly of the stopper 10 can maintain sufficient mounting strength even under high temperatures.

[0085] Figure 10 This is a non-limiting example in which the pressurizing portion 13 is formed as a convex portion instead of a curved piece. Additionally or alternatively, the pressurizing portion 14 may also be formed as a convex portion instead of a curved piece.

[0086] The above description will make the manufacturing method of the zipper 1 obvious to those skilled in the art. As a summary, first, a polyurethane film is bonded to the upper surface of a zipper chain consisting of zipper tapes 2m and 2n, which are engaged with spiral members 6m and 6n, using an adhesive. A thermosetting adhesive can be used as the adhesive, but a thermoplastic adhesive can also be used depending on the situation. For this bonding purpose, a method can be employed in which the laminated body of the zipper chain and the polyurethane film is passed through the gap between the lower roller and the upper roller, thereby pressing them together.

[0087] Next, a cutter is used to form a cutting line on the polyurethane film along the center line of the zipper chain, thereby dividing the polyurethane film for each zipper chain tape 2m, 2n. Next, a space portion is formed at a specified interval along the length direction of the zipper chain. Specifically, the continuous spiral members 6m, 6n are removed at specified intervals to ensure the installation area of ​​the stop code. Next, a reinforcement is attached to the lower surface of the zipper tape at the space portion of the zipper chain with the polyurethane film. At the same time or continuously therewith, the reinforcement is knurled. Thereafter, the zipper chain with the polyurethane film is cut at the space portion to cut out a zipper chain of a specified length. The rod member 11 is pressed and fixed to the zipper chain tape 2m on one side of the zipper chain cut out in this way, and the seat member 12 is pressed and fixed to the zipper chain tape 2n on the other side. In this way, a zipper 1 with a detachable stop code 10 can be manufactured.

[0088] The rod member 11 and the seat member 12 are pressed and fixed to the laminated parts 71 and 72, which include both a soft waterproof film and a hard reinforcement. In this regard, the rod member 11 and the seat member 12 (for example, the seat rod 12b thereof) can be locally plastically deformed. Even so, since the laminated parts 71 and 72 include both a soft waterproof film and a hard reinforcement, the generation of cracks in the reinforcement can be suppressed. In addition to or instead of this feature, the reinforcements 5m and 5n can be thicker than the waterproof films 4m and 4n. Even if the rod member 11 and the seat member 12 are pressed and fixed to the laminated parts 71 and 72, since the laminated parts 71 and 72 include both a soft waterproof film and a hard reinforcement, the generation of cracks in the reinforcement can be suppressed.

[0089] It is obvious to those skilled in the art that the above-mentioned manufacturing process includes the following steps: the manufacturing method of the slide fastener disclosed herein includes: a step of laminating the first waterproof film 4m, the first zipper tape 3m, the first core cord 7m, and the first reinforcement 5m to form the first laminated portion 71; a step of laminating the second waterproof film 4n, the second zipper tape 3n, the second core cord 7n, and the second reinforcement 5n to form the second laminated portion 72; a step of partially plastically deforming the rod member 11 to press and secure it to the first laminated portion 71; and a step of partially plastically deforming the seat rod 12b of the seat member 12 to press and secure it to the second laminated portion 72.

[0090] In some cases, a universal slider is provided with a separator strip 86. However, in this case, there is a concern that the separator strip 86 may contact the waterproof films 4m and 4n, thereby increasing the sliding resistance of the slider 8. This specification also discloses an invention that helps reduce the sliding resistance of the slider 8 to address this issue. Furthermore, customizing a slider without a separator strip 86 may increase the cost of the zipper 1.
