Description

Technical Field

[0001] This invention relates to products with zippers. Background Technology

[0002] For example, International Publication No. 2011 / 064893 (Patent Document 1) describes a waterproof zipper. To put it simply, the zipper described in Patent Document 1 has a pair of left and right zipper teeth with rows of teeth and a zipper pull that is slidably mounted on the left and right rows of teeth.

[0003] Each zipper belt on the left and right sides has a zipper belt (belt member) and multiple zipper teeth provided on the side edge of the zipper belt. The zipper belt includes a narrow belt body with water resistance and the like, and a core wire portion provided on the side edge of the belt body. In addition, the zipper belt has the property of preventing liquid from seeping into the back side of the zipper belt from the surface side.

[0006] Patent Document 1: International Publication No. 2011 / 064893 Summary of the Invention

[0007] The problem that the invention aims to solve

[0008] When the zipper described in Patent Document 1 is installed on a product such as clothing or a bag, for example, the zipper tape of the zipper teeth overlaps with the component of the product on which the zipper is to be installed (such as the fabric of the clothing), and the zipper tape and the component on which the zipper is to be installed are sewn together using a sewing machine.

[0009] In conventional sewing processes, the zipper tape and the zipper mounting portion of the component to which the zipper is to be installed are typically inserted into the sewing machine between the needle plate and presser foot in an overlapping manner, thereby sewing the zipper tape and the zipper mounting edge together. In this case, considering the positional relationship between the presser foot and needle and the zipper teeth of the zipper tape during sewing, the sewing machine needle needs to reciprocate up and down at a position where the zipper tape is separated from the zipper teeth in the tape width direction to pierce the zipper tape. As a result, the sewn portion of the thread that joins the zipper tape and the component to which the zipper is to be installed is formed at a position where it is separated from the zipper teeth in the tape width direction; therefore, the zipper tape is positioned to be exposed to the outside between the zipper teeth and the component to which the zipper is to be installed.

[0010] Thus, when the zipper tape is exposed between the zipper teeth and the component where the zipper is to be installed, in order for the zippered product to have at least water resistance, not only must the fabric of the product, which serves as the component where the zipper is installed, be water-resistant, but the zipper tape itself also needs to possess the water resistance described in Patent Document 1. However, imparting water resistance to the zipper tape requires specialized equipment or materials, thus leading to problems such as increased manufacturing costs and increased complexity in the manufacturing process.

[0011] In addition, in products with zippers, the zipper is sometimes considered as a design element. Therefore, to improve the design or appearance of products with zippers, it is sometimes required that the zipper tape be invisible or difficult to see.

[0012] The present invention was made in view of the above-mentioned problems, and its object is to provide a zippered product that allows for easy sewing of the zipper tape and the component to which the zipper is to be installed, and improves water resistance by preventing or suppressing the zipper tape from being exposed between the zipper teeth and the component to which the zipper is to be installed, and also improves design or appearance quality.

[0013] [Methods used to solve problems]

[0014] To achieve the above objectives, the zippered product of the present invention comprises: a zipper tooth tape having a plurality of zipper teeth arranged at certain intervals along the length of the tape; and a component for mounting the zipper, having a pair of tooth tape mounting edges at opposite positions for mounting a pair of the zipper tooth tapes, wherein the zipper tooth tapes are mounted to the tooth tape mounting edges by a sewn portion formed by a sewn thread, and the tooth tape mounting edges, when viewed in cross-section orthogonal to the length of the tape, have a double-layered portion bent into a U-shape, the double-layered portion in the cross-section... It has: a first strip portion, which is disposed separately from the zipper strip; a bent portion, which extends from the first strip portion and has a bent shape; and a second strip portion, which extends from the bent portion and is disposed overlapping the first strip portion, a portion of the sewn portion is sandwiched between the first strip portion and the second strip portion in the double layer portion, the sewn portion is disposed separately from the plurality of zipper teeth, and the bent portion is disposed in contact with or close to the plurality of zipper teeth, and a water-resistant area is formed between the sewn portion and the plurality of zipper teeth.

[0015] In the zippered product of the present invention, it is preferable that the bent portion and the sewn portion are disposed off the ground and are disposed in contact with the zipper teeth.

[0016] In this case, it is preferable that at least a portion of the zipper tape and the second tape portion are bonded together in the area between the bend and the sewn portion.

[0017] Alternatively, preferably, the bent portion is formed by heat treatment to maintain the bent shape of the bent portion.

[0018] Furthermore, preferably, the sewn part is arranged separately from the zipper teeth at a separation distance of 0.5 mm or more and 10.0 mm or less in the width direction of the zipper tape.

[0019] Furthermore, it is preferable that the thickness of the zipper tape in the double-layer portion, from the outer surface of the first tape portion to the outer surface of the second tape portion, is 0.25 mm or more and 5.0 mm or less.

[0020] In the zippered product of the present invention, it is preferable that the bent portion is formed in the left-right direction at a position close to the formation position of the sewing portion and is configured close to the plurality of zipper teeth, and the sewing portion is configured to be separated from the zipper teeth by a separation distance of 0.5 mm or more and 3.0 mm or less in the width direction of the zipper tape.

[0021] In the zippered product of the present invention described above, it is preferred that each zipper tooth has: a tooth base having a portion having a fixed dimension in the thickness direction of the zipper tape; and a wing extending from the tooth base toward the inner side of the zipper tape, wherein the dimension in the thickness direction is smaller than the dimension in the thickness direction of the tooth base.

[0022] [Invention Effects]

[0023] The zippered product according to the present invention improves water resistance and enhances design or appearance quality by preventing or suppressing the zipper tape from being exposed between the zipper teeth and the component on which the zipper is to be installed.

[0033] The applicant has filed a PCT application (PCT / JP2022 / 032020) concerning a zippered product manufactured by sewing the zipper tape to the mounting edge of the component on which the zipper is to be mounted, which features a characteristic in the interlacing portion of the sewn part. By using the technology described in the PCT application, it is possible to make the sewn part contact the zipper teeth, thereby preventing or suppressing the zipper tape from being exposed between the zipper teeth and the component (fabric) on which the zipper is to be mounted.

[0034] In contrast, in the zippered products shown in the following embodiments, even without the sewn portion contacting the zipper teeth, it is possible to prevent or suppress the zipper tape from being exposed between the zipper teeth and the component (fabric) on which the zipper is to be installed. Furthermore, while the sewn portion formed in the aforementioned PCT application is formed by a sewing machine thread comprising a top thread and a bottom thread, in this case, the sewing thread forming the sewn portion can also be water-repellent. This further improves the water resistance of the zippered product.

[0035] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0036] [Example 1]

[0037] Figure 1 This is a schematic top view of the zippered product of Embodiment 1. Figure 2 , Figure 3 and Figure 4 These are three-dimensional, bottom, and sectional views that enlarge and schematically represent a portion of a product with a zipper.

[0038] In the following description of zippers and products with zippers, the front-back direction refers to the direction along the length of the zipper tape, which is the same direction as the sliding direction of the zipper pull (see reference). Figure 1 and Figure 2 In particular, the direction in which the zipper pull slides when the zipper is closed is set to forward, and the direction in which the zipper pull slides when the zipper is opened is set to backward.

[0039] The left-right direction refers to the direction along the width of the zipper tape; specifically, it is the direction orthogonal to the front-back direction and parallel to the surface and back of the zipper tape. Alternatively, the left-right direction can also be described as the direction along which the teeth of a pair of zipper teeth engage and disengage. In this case, the direction in which a pair of teeth move closer together is defined as the inner direction of the left-right direction, and the direction in which a pair of teeth move apart is defined as the outer direction of the left-right direction (see reference). Figure 3 ).

[0040] The up-down direction refers to the direction perpendicular to the surface and back of the zipper tape (the direction between the front and back of the tape), and is perpendicular to the front-back and left-right directions (see reference). Figure 4 The up-down direction is sometimes also called the thickness direction. In this case, the direction exposed to the outside when using the zipper (e.g., the direction of the pull tab of the zipper head relative to the zipper tape) is set as up, and the opposite direction is set as down.

[0041] The zippered product 1 in this embodiment 1 is, for example, clothing, in which zippers 20 are installed at the front opening of the front body and at the opening and closing parts (opening perimeters) of the pockets provided on the chest and abdomen of the front body. The zippered clothing 1 includes: a zipper 20 having a pair of left and right zipper teeth 21; and a component 10 for installing the zipper, which has left and right tooth zipper mounting edges 11 for mounting the left and right zipper teeth 21.

[0042] In this embodiment 1, the component 10 on which the zipper 20 is to be installed is the fabric 10 of the garment (also called clothing fabric). Furthermore, the left and right sides of the fabric 10 forming the front of the garment each have opposing side edges 11 arranged opposite to the fabric 10 on the target side. These opposing side edges 11 of the left and right fabrics 10 serve as zipper belt mounting edges 11 for mounting the zipper belt 21 of the zipper 20.

[0043] In this embodiment 1, the fabric 10 having the left and right sides of the toothed chain mounting edge 11 is at least water-resistant. Here, water resistance refers to the property of inhibiting water from passing through or penetrating the fabric 10. Furthermore, in this embodiment 1, the method and means of imparting water resistance to the fabric 10 are not particularly limited. Alternatively, the fabric 10 may also be formed without water resistance.

[0044] Each of the left and right fabrics 10 has a main fabric portion (not shown) and a zipper toothed belt mounting edge portion 11 provided at the end edge of the main fabric portion. A zipper toothed belt 21 is mounted on the zipper toothed belt mounting edge portion 11 of each fabric 10 using a sewing portion 12 formed by sewing thread (sewing machine thread).

[0045] like Figure 4 As shown, the zipper belt mounting edge 11 of each fabric 10 has a double-layered portion 14 formed by overlapping the fabric 10 of the garment in the vertical direction. By folding the fabric 10 of the garment back at the bend 16 along the front-back direction, the double-layered portion 14 of the zipper belt mounting edge 11 is formed into a U-shaped form when viewed orthogonally to the front-back direction. In this case, the double-layered portion 14 is formed in contact with the wing 23b (second wing 25b) of the zipper teeth 23, which will be described later.

[0046] The double-layered portion 14, when viewed in a cross-section orthogonal to the front and back directions, has: a first strip portion 15 that extends from the main body of the fabric portion (not shown) toward the inside in the width direction; a bent portion 16 that extends from the first strip portion 15 while being bent; and a second strip portion 17 that extends from the bent portion 16 and overlaps with the first strip portion 15 in the vertical direction.

[0047] In this double-layered portion 14, the first strip 15 is disposed above the second strip 17, separated from the zipper strip 22 (described later) of the zipper tooth strip 21. The second strip 17 is disposed in contact with the zipper strip 22. The second strip 17 is disposed vertically between the zipper strip 22 and the first strip 15. The bent portion 16 is disposed horizontally at a position that separates from the formation position of the sewn portion 12 towards the inside of the zipper 20 and is closer to the zipper tooth 23 (described later) than the formation position of the sewn portion 12.

[0048] The double-layer portion 14 has inner surfaces of the fabric 10 facing each other and an outer surface disposed on the opposite side of the inner surfaces. In this case, the inner surface of the double-layer portion 14 has a lower surface of the first strip portion 15, an inner peripheral surface of the bent portion 16, and an upper surface of the second strip portion 17. The outer surface of the double-layer portion 14 has an upper surface of the first strip portion 15, an outer peripheral surface of the bent portion 16, and a lower surface of the second strip portion 17. The lower surface of the second strip portion 17 can also be described as the strip-facing surface opposite to the zipper tape 22.

[0049] The sewn part 12, which sews the zipper toothed edge 11 of fabric 10 to the zipper toothed strap 21, is arranged in a straight line along the front and back direction of the zipper strap 22 by using a sewing machine (not shown) to perform a flat sewing process (see reference). Figure 3 The sewn section 12 is formed by a sewing thread that includes the top thread (needle thread) and the bottom thread (boob thread) of a sewing machine. In addition, the sewing thread forming the sewn section 12 may also be water-repellent.

[0050] A straight stitch 12 sews the second strip 17 of the double-layered portion 14 to the zipper strip 22, thereby fixing the zipper tooth strip 21 to the tooth strip mounting edge 11 of the fabric 10. Furthermore, in this invention, the stitching portion that sews the tooth strip mounting edge to the zipper tooth strip can also be formed with a portion that is slightly bent or curved inward or outward in the left-right direction.

[0051] In this embodiment 1, the sewn portion 12 is positioned in the left-right direction at a position separated from the zipper teeth 23 on the outer side (inner side of the zipper tape 22) in the left-right direction, and is also positioned in the left-right direction separated from the outer side of the bent portion 16 of the zipper tape mounting edge 11. At this time, the bent portion 16 of the zipper tape mounting edge 11 is positioned in contact with the zipper teeth 23, and in the left-right direction, the portion of the double-layer portion 14 between the position of the sewn portion 12 and the position of the bent portion 16 is formed as a wing on the zipper tape 22. Thus, a water-resistant area is formed between the sewn portion 12 and the zipper teeth 23.

[0052] In this case, the lateral separation distance between the sewn part 12 and the zipper tooth 23 (described later) is preferably 1 mm or more and 10.0 mm or less. By making the separation distance 1 mm or more, the first adhesive layer 31 (described later) can be stably disposed between the zipper tape 22 and the toothed tape mounting edge 11. By making the separation distance 10.0 mm or less, the width dimension (lateral dimension) of the zipper tape 22 and the width dimension of the second tape part 17 can be prevented from becoming too large. As a result, the manufacturing cost of the zippered garment 1 can be reduced. When the separation distance is greater than 10.0 mm, it is sometimes difficult to position and bend the zipper with the bending part 16 in contact with the zipper tooth 23.

[0053] In this embodiment 1, a portion of the sewn part 12 is configured to be sandwiched between the first strip portion 15 and the second strip portion 17. In other words, a portion of the sewn part 12 is held inside the double-layer portion 14. In this case, the portion of the sewn part 12 sandwiched between the first strip portion 15 and the second strip portion 17 is the portion of the sewn part 12 disposed above the upper surface of the second strip portion 17.

[0054] In the zippered product 1 of this embodiment 1, a first adhesive layer 31 is provided between the upper surface of the zipper tape 22 and the lower surface of the second tape portion 17 to bond the zipper tape 22 and the double-layer portion 14. This first adhesive layer 31 is preferably provided at least in the left-right direction near the zipper teeth 23 between the zipper tape 22 and the second tape portion 17. For example, in the case of this embodiment 1, the first adhesive layer 31 is continuously provided in the left-right direction from the position (or near it) of the boundary between the bend portion 16 in the double-layer portion 14 and the second tape portion 17 to the position of the sewn portion 12.

[0055] By providing such a first adhesive layer 31, the double-layer portion 14 (particularly the second strip portion 17) of the zipper tape mounting edge 11 can be stably fixed to the zipper tape 22, thus preventing the double-layer portion 14 from separating from the zipper tape 22 and rolling up. As a result, the zipper tape 22, which is hidden under the double-layer portion 14, can be prevented from being exposed to the outer surface of the zippered product 1 (clothing) due to the rolling up of the double-layer portion 14. Furthermore, in this invention, the first adhesive layer only needs to be provided in the left-right direction in at least a portion of the area sandwiched between the zipper tape and the second strip portion.

[0056] In this embodiment 1, a second adhesive layer 32 is provided between the lower surface of the first strip portion 15 and the upper surface of the second strip portion 17 of the double-layer portion 14 to bond the first strip portion 15 and the second strip portion 17 together. By providing this second adhesive layer 32, the U-shaped shape of the double-layer portion 14 can be stably maintained.

[0057] Furthermore, in this invention, the material and thickness of the first adhesive layer 31 and the second adhesive layer 32 are not particularly limited. Additionally, in this invention, a product with a zipper can be formed without providing a second adhesive layer between the first strip portion and the second strip portion.

[0058] The zipper 20 of this embodiment 1 includes: a pair of left and right zipper tooth straps 21, each pair having a tooth row 26 formed on the side edge of the zipper strap 22; and a zipper pull 40, which is slidably mounted to the left and right tooth rows 26. In this embodiment 1, the left and right zipper tooth straps 21 are mounted to the tooth strap mounting edges 11 of the left and right fabrics 10 using the aforementioned sewing portion 12 (see reference). Figure 1 and Figure 2 ).

[0059] In this embodiment 1, the zipper pull 40 is formed substantially the same as the zipper pull described in International Publication No. 2011 / 064893 (Patent Document 1) or International Publication No. 2017 / 094145. Here, the zipper pull 40 of this embodiment 1 will be briefly described. The zipper pull 40 has a zipper pull body 41 and a pull tab 45 mounted on the zipper pull body 41. The zipper pull body 41 has an upper wing plate 42, a lower wing plate (not shown) arranged parallel to the upper wing plate 42, a connecting post (not shown) connecting the front end of the upper wing plate 42 and the front end of the lower wing plate, left and right upper flange portions (not shown) extending from the left and right side edges of the upper wing plate 42 toward the lower wing plate, left and right lower flange portions (not shown) extending from the left and right side edges of the lower wing plate toward the upper wing plate 42, and a pull tab mounting portion 43 integrally formed on the upper surface of the upper wing plate 42 for mounting the pull tab 45.

[0060] At the front end of the zipper pull body 41, left and right shoulder openings are provided, separated by a connecting post. At the rear end of the zipper pull body 41, a rear opening is provided. A roughly Y-shaped zipper tooth guide path, communicating with the left and right shoulder openings and the rear opening, is provided between the upper wing plate 42 and the lower wing plate of the zipper pull body 41. A through-gap is provided between the upper and lower flange portions of the zipper pull body 41, through which the first wing portion 24b and the second wing portion 25b of the zipper tooth 23 (described later) pass. This through-gap communicates with the zipper tooth guide path.

[0061] Each of the left and right zipper belts 21 has a long and narrow zipper belt 22 and a plurality of synthetic resin zipper teeth 23 provided on the side edge of the zipper belt 22. In this case, the zipper teeth 23 are provided on the side edge of the zipper belt 22 opposite to the zipper belt 21 that is the object of engagement.

[0062] Each zipper tape 22 includes: a tape body portion 22a, which has a tape surface and a tape back surface; and a core wire portion 22b, which is disposed on the inner side edge of the tape body portion 22a. The core wire portion 22b is integrally disposed on the side edge of the tape body portion 22a along the tape length direction. The core wire portion 22b is formed to bulge in the vertical direction relative to the tape body portion 22a.

[0063] In this embodiment 1, the zipper tape 22 does not have a waterproof layer to prevent or inhibit water intrusion, and is therefore not water-resistant. Furthermore, in this invention, the structure and properties of the zipper tape, as well as the method of forming the zipper tape 22, are not particularly limited, and the zipper tape 22 may also be water-resistant in at least a portion.

[0064] On the side edge of the zipper tape 22, a plurality of synthetic resin zipper teeth 23 are arranged at certain intervals along the front-to-back direction, thereby forming a tooth row 26. Each zipper tooth 23 is formed by injection molding synthetic resin onto the zipper tape 22. Each zipper tooth 23 is not connected to other zipper teeth 23 adjacent to it in the front-to-back direction, and has a shape that is separate from and independent of other zipper teeth 23.

[0065] Each zipper tooth 23 includes at least: a tooth base 23a having a portion of a certain thickness; and a wing 23b extending from the tooth base 23a outward in a left-right direction (in other words, the inner side of the zipper tape 22). The wing 23b is formed with a thickness smaller than that of the tooth base 23a. Here, thickness refers to the dimension in the vertical direction, and the thickness of the tooth base 23a is the dimension in the vertical direction from the upper surface to the lower surface of the tooth base 23a. The wing 23b has a first wing 24b (described later) on the lower surface side and a second wing 25b (described later) on the upper surface side.

[0066] By providing wings 23b to each zipper tooth 23, when the zipper pull 40 slides along the tooth row 26, the upper and lower flanges of the zipper pull 40 can be accommodated and pass through a gap formed on the outer side in the left-right direction of the step portion between the tooth base 23a and the wing 23b. Therefore, when the zipper pull 40 slides, it is less likely to snag on the toothed edge 11 of the fabric 10, thus allowing for smooth sliding of the zipper pull 40.

[0067] To describe the shape of the zipper teeth 23 in more detail, each zipper tooth 23 has a first tooth portion 24 disposed on the back side of the zipper tape 22 and a second tooth portion 25 disposed on the surface side of the zipper tape 22 and having a different shape from the first tooth portion 24. In this case, the first tooth portion 24 of the zipper tooth 23 is the portion hidden on the back side of the zippered garment 1. The second tooth portion 25 is the portion exposed to the outside of the garment.

[0068] Although specific illustrations are omitted, the first zipper tooth 24 has: a first main body that is directly fixed to the zipper tape 22; a first wing 24b that extends outward from the first main body in the left-right direction; a neck that extends inward from the first main body in the left-right direction; and an engaging head 24a that extends further inward from the neck in the left-right direction, and is generally oblong in shape when viewed from below the zipper tooth 23.

[0069] When the first main body is viewed from below the zipper teeth 23 ( Figure 3It has a roughly isosceles trapezoidal shape. The neck has a constricted shape that engages with the engagement heads 24a of the two zipper teeth 23 that are engaged. The first wing 24b extends outward from the first main body in the left-right direction and is formed such that its thickness is smaller than that of the first main body by means of the first step 24c. Here, the thickness of the first main body refers to the vertical dimension from the back of the zipper tape 22 to the lower surface of the first main body, and the thickness of the first wing 24b refers to the vertical dimension from the back of the zipper tape 22 to the lower surface of the first wing 24b.

[0070] like Figure 2 As shown, the second zipper tooth portion 25 has a second main body portion 25a directly fixed to the zipper tape 22, a second wing portion 25b extending outward from the second main body portion 25a in the left-right direction, and a zipper tooth head 25c extending inward from the second main body portion 25a in the left-right direction. The zipper tooth head 25c has a shape in which the dimensions in the length direction decrease in two stages towards the top of the zipper tooth head 25c.

[0071] The second wing 25b extends outward from the second main body 25a in the left-right direction and is formed such that its height dimension measured from the zipper tape 22 is smaller than the height dimension of the second main body 25a measured from the zipper tape 22, via the second step 25d.

[0072] The outer side face of the second wing 25b in the width direction contacts the toothed zipper belt mounting edge 11 of the fabric 10. Furthermore, the contact between the second wing 25b of the zipper tooth 23 and the toothed zipper belt mounting edge 11 of the fabric 10 is maintained by the first adhesive layer 31 formed between the zipper belt 22 and the second strip portion 17.

[0073] By maintaining the zipper belt mounting edge 11 (double-layer portion 14) of the fabric 10 in contact with the second wing 25b of the zipper teeth 23 through the first adhesive layer 31, the zipper belt mounting edge 11 of the fabric 10 can stably cover the portion of the zipper belt 22 except for a portion (specifically, the portion of the zipper belt 22 disposed between adjacent zipper teeth 23). Therefore, it is possible to prevent the zipper belt 22 from being exposed within the range between the zipper teeth 23 and the component 10 on which the zipper is to be mounted in the left-right direction.

[0074] In the zipper tooth 23 of this embodiment 1, the first wing 24b and the second wing 25b have shapes that are symmetrical about each other in the vertical direction with respect to the zipper tape 22. Furthermore, the wing 23b having the first wing 24b and the second wing 25b is formed with a thickness sufficient to be inserted into the tape through-gap of the zipper pull 40. The first step portion 24c and the second step portion 25d of the zipper tooth 23 are formed to allow sliding contact with the upper flange portion and the lower flange portion of the zipper pull 40, respectively.

[0075] By providing the first wing 24b and the second wing 25b to the zipper teeth 23, even if the mounting edge 11 of the fabric 10 is kept in contact with the second wing 25b of the zipper teeth 23 as described above, it is possible to prevent or suppress the upper and lower flanges of the zipper head 40 from contacting the left and right fabrics 10 when the zipper head 40 slides along the left and right rows of teeth 26. Therefore, the zipper head 40 can be smoothly slid regardless of the thickness of the fabric 10.

[0076] Alternatively, in this invention, zipper teeth can be formed without the first and second fins. In this case, it is preferable to provide a concave through-groove in the zipper teeth for the upper and / or lower flanges of the zipper pull to pass through. By providing such a through-groove in the zipper teeth, the zipper pull can also be slid smoothly.

[0077] Furthermore, by providing each zipper tooth 23 with the first tooth portion 24 and the second tooth portion 25 as described above, water is less likely to seep from the upper surface of the left and right tooth rows 26 into the lower surface when the left and right tooth rows 26 are engaged. Additionally, by making each zipper tooth 23 water-repellent, water ingress is even less likely. Moreover, in this invention, the shape of the zipper teeth is not particularly limited; the zipper teeth only need to have a shape that allows the left and right tooth rows to engage.

[0078] Next, a method for manufacturing a zippered garment 1 by attaching the zipper teeth 21 of the zipper 20 to the tooth attachment edge 11 of the fabric 10 will be described.

[0079] Furthermore, in the following description of the sewing machine and sewing method, the front-to-back direction is the transport direction of the sewing machine, which is the direction along which the zipper teeth 21 and the fabric 10, which are the objects to be sewn, are transported. In this case, the direction in which the objects to be sewn are transported is defined as forward, and the opposite direction is defined as rearward. The up-down direction is the direction along which the sewing machine needle reciprocates. In this case, the direction in which the sewing machine needle pierces the objects to be sewn is defined as downward, and the direction in which the sewing machine needle is pulled out of the objects to be sewn is defined as upward. The left-right direction is the direction orthogonal to the transport direction of the objects to be sewn and the direction orthogonal to the reciprocating motion direction of the sewing machine needle.

[0080] First, use a sewing machine, such as Figure 5 The sewing process (sewing process) involves stitching the zipper strap 22 of the zipper chain strap 21 and the mounting edge 11 of the fabric 10 together as shown. Furthermore, in Figure 5 and Figure 6 In the middle, the zipper tooth belt 21 and the tooth belt mounting edge 11 are shown in such a way that their upper and lower orientations are opposite.

[0081] The sewing machine used in the sewing process of this embodiment 1 is a sewing machine that sews the zipper chain strap 21 and the chain strap mounting edge 11 together by a flat stitch. Furthermore, in this invention, the sewing machine used in the sewing process is not particularly limited.

[0082] In this sewing process, firstly, the zipper chain strap 21 and the chain strap mounting edge 11 of the fabric 10 are placed on the needle plate of the sewing machine (not shown) in a predetermined positional relationship. Then, the presser foot of the sewing machine (not shown) is lowered, thereby clamping and holding the zipper chain strap 21 and the chain strap mounting edge 11 between the presser foot and the needle plate. At this time, the chain strap mounting edge 11 of the fabric 10 remains flat, and the U-shaped double-layered portion 14 has not yet formed on the chain strap mounting edge 11. Furthermore, the vertical positional relationship between the zipper chain strap 21 and the chain strap mounting edge 11 is not particularly limited during the sewing process.

[0083] After holding the zipper chain strap 21 and the chain strap mounting edge 11 in a predetermined position, the sewing machine's feed mechanism intermittently feeds the zipper chain strap 21 and the chain strap mounting edge 11 of the fabric 10, and the sewing machine needle reciprocates in the up-down direction in accordance with the timing of this feed. As a result, the sewing machine needle pierces the zipper chain strap 22 and the chain strap mounting edge 11 to perform a flat stitch. Through this flat stitch, a straight seam 12 is formed along the front-back direction by the sewing machine threads (top thread and bottom thread), and the zipper chain strap 22 and the chain strap mounting edge 11 are sewn together using this seam 12.

[0084] At this time, a straight sewing section 12, made of sewing machine thread, is formed at a location where it separates from the zipper teeth 23 in the left-right direction. Therefore, compared to, for example, forming the sewing section at the position where it contacts the zipper teeth, a dedicated conveying mechanism for transporting the zipper teeth is not required, thus making sewing machine processing easier. In addition, the cost required for the sewing process can be reduced. Moreover, the sewing section 12 formed by this sewing process is positioned at a position where it separates from the bent portion 16 of the double-layer portion 14 in the left-right direction when the toothed belt mounting edge 11 is bent to form the double-layer portion 14 in a subsequent process.

[0085] After the above sewing process, a bending process is performed to bend the toothed chain strap mounting edge 11 of the fabric 10 to form a double-layered part 14.

[0086] In this bending process, the zipper belt mounting edge 11 of the fabric 10 is bent so that the first belt portion 15 and the second belt portion 17 of the zipper belt mounting edge 11 overlap vertically. At this time, the zipper belt mounting edge 11 is bent such that the bent portion 16 formed in the double layer portion 14 contacts the zipper teeth 23 (especially the wing portion 23b). Thus, a zipper belt with sewn-on teeth 21 and forming a zipper belt mounting edge 11 is produced. Figure 6 The fabric 10 of the toothed chain belt mounting edge 11 of the double-layered part 14 as shown.

[0087] Furthermore, through this bending process, a portion of the sewn part 12 is sandwiched between the first strip 15 and the second strip 17 of the double-layer part 14, and is thus kept in a state of being wrapped by the double-layer part 14. Additionally, the second strip 17 of the double-layer part 14 is arranged above the sewn part 12 to cover it. Therefore, the sewn part 12 is obscured by the second strip 17 and is not visible from the upper surface (outer surface) side of the toothed chain mounting edge 11.

[0088] Next, the following bonding process is performed: adhesive 31a and 32a are applied to the fabric 10 with the double-layered portion 14 and the zipper toothed strap 21 formed by the bending process to form a first adhesive layer 31 and a second adhesive layer 32.

[0089] In this bonding process, such as Figure 6 As shown, the first adhesive layer 31 is formed by applying adhesive 31a to the upper surface of the zipper tape 22 and / or the lower surface of the second tape portion 17. This first adhesive layer 31 is used to fix the zipper tape 22 and the second tape portion 17. Furthermore, hot-melt adhesives, reaction-curing adhesives, etc., are used as adhesives 31a and 32a.

[0090] Furthermore, the second adhesive layer 32 is formed by applying adhesive 32a to the upper surface of the second strip portion 17 and / or the lower surface of the first strip portion 15 in the double-layer portion 14. This second adhesive layer 32 is used to fix the second strip portion 17 and the first strip portion 15. In this case, the order in which the first adhesive layer 31 and the second adhesive layer 32 are formed is not particularly limited. Additionally, in this invention, the formation of the second adhesive layer 32 may be omitted.

[0091] By performing the above-mentioned sewing, bending, and gluing processes, a product is thus manufactured. Figures 2-4The fabric 10 shown has a zipper toothed chain strap 21 sewn onto the toothed chain strap mounting edge 11. At this time, the sewn part 12 that sews the zipper toothed chain strap 21 and the toothed chain strap mounting edge 11 is covered by the first strip part 15 of the toothed chain strap mounting edge 11, so that the sewn part 12 can be not seen from the outer surface of the fabric 10.

[0092] Furthermore, in this embodiment 1, the sewing process, bending process, and bonding process are performed sequentially as described above. However, in this invention, the order in which the sewing process, bending process, and bonding process are performed is not particularly limited; for example, the bending process and bonding process may be performed before the sewing process.

[0093] Next, the fabric 10 with the zipper teeth 21 sewn on is assembled in pairs, and a zipper pull 40 is installed on the zipper teeth row 26 of the set of zipper teeth 21, thereby making a zippered fabric 10. By using the zippered fabric 10 to form a garment, a zippered garment 1 is manufactured.

[0094] Furthermore, in this embodiment 1, for example, after forming a garment using two pieces of fabric 10 with sewn-on zipper teeth 21, a zipper pull 40 can be installed on the two rows of zipper teeth 26 provided on the garment, thereby manufacturing a zippered garment.

[0095] In the zippered garment of this embodiment 1 manufactured as described above, the sewing part 12, which sews together the zipper tooth tape 21 and the tooth tape mounting edge 11, is provided separately from the zipper tooth 23 in the left-right direction, and the zipper tape 22 and the double layer 14 (especially the second tape 17) are bonded to each other by the first adhesive layer 31.

[0096] Therefore, according to the zippered garment 1 of this embodiment 1, the first adhesive layer 31 can prevent the double-layer portion 14 from rolling up relative to the zipper teeth 21, and can stably maintain the double-layer portion 14 in contact (or close to) with the zipper teeth 23. As a result, the zipper tape 22 can be prevented from being exposed to the outside from between the zipper teeth 23 and the component 10 on which the zipper is to be installed.

[0097] As described above, in the zippered garment 1 of this embodiment 1, the zipper tape 22 is substantially entirely covered and hidden from the outer surface (upper side) by the toothed zipper tape mounting edge 11 of the fabric 10, thus reducing the exposed portion of the zipper tape 22. Therefore, it is possible to prevent or suppress damage to the design and appearance quality of the garment due to the exposure of the zipper tape 22, and thus it is easy to manufacture garments with excellent design or high appearance quality.

[0098] Furthermore, in this embodiment 1, as described above, the exposed portion of the zipper tape 22 can be reduced. Additionally, a water-resistant area formed by a portion of the double-layer portion 14 (flaps) is provided between the zipper teeth 23 and the sewing portion 12. Therefore, even if the zipper tape 22 itself is not water-resistant, as long as the fabric 10 of the garment is at least water-resistant, it is not easy for liquids such as water to seep into the garment from the surface side to the back side via, for example, the portion of the zipper 20 provided on the garment. Furthermore, in this case, since the zipper tape 22 is not given water resistance, advantages such as reduced manufacturing costs and simplified manufacturing processes can also be obtained.

[0099] [Example 2]

[0100] Figure 7 This is a cross-sectional view schematically showing a portion of the zippered product of this embodiment 2, orthogonal to the front-back direction.

[0101] The zippered product 2 of this embodiment 2 is, like the aforementioned embodiment 1, clothing. The zippered clothing 2 of this embodiment 2 includes: a zipper 20 having a pair of left and right zipper teeth 21; and a component (fabric) 50 for mounting the zipper, having left and right tooth mounting edges 51 for mounting the left and right zipper teeth 21.

[0102] The zippered garment 2 of this embodiment 2 differs from the zippered garment 1 described in embodiment 1 in the following two aspects. Firstly, the zippered garment 2 of this embodiment 2 does not have the first adhesive layer 31 and the second adhesive layer 32 described in embodiment 1. Secondly, in the zippered garment 2 of this embodiment 2, the double-layered portion 54 of the fabric 50 (particularly the bent portion 56) has the property of maintaining its bent shape through heat treatment (e.g., heat setting treatment).

[0103] Furthermore, apart from the two differences mentioned above, the zippered garment 2 of this embodiment 2 is formed in essentially the same way as the zippered garment 1 described in embodiment 1. For example, the zipper teeth 21 used in this embodiment 2 is formed in essentially the same way as the zipper teeth 21 described in embodiment 1.

[0104] Therefore, in the descriptions related to Embodiment 2 and Embodiments 3 and 4 below, the same reference numerals as in Embodiment 1 are used to represent parts and components that are substantially the same as those in Embodiment 1, thereby omitting detailed descriptions thereof.

[0105] The left and right fabrics 50 used in the garment 2 of this embodiment 2 are at least water-resistant. Each left and right fabric 50 has a main fabric portion (not shown) and a toothed chain strap mounting edge portion 51 provided at the end edge of the main fabric portion. The toothed chain strap mounting edge portion 51 of each fabric 50 has a double-layer portion 54 in which the fabric 50 of the garment overlaps in the vertical direction to form a letter U-shape.

[0106] In this embodiment 2, the double-layer portion 54, when viewed in cross-section orthogonal to the front-back direction, comprises: a first strip portion 55 extending inward from the main fabric portion (not shown) in the width direction; a bending portion 56 extending from the first strip portion 55 while bending; and a second strip portion 57 extending from the bending portion 56 and overlapping the first strip portion 55. A zipper tooth strip 21 is sewn onto the second strip portion 57 of the double-layer portion 54 using a sewing portion 12. The double-layer portion 54 is formed in contact with the wing portion 23b (second wing portion 25b) of the zipper tooth 23.

[0107] The double-layer portion 54 of this embodiment 2 possesses the property that, when heat treatment, such as heat setting, is performed on a state having, for example, a U-shaped or similar shape, the bent portion 56 can maintain its bent shape. In other words, the double-layer portion 54 of this embodiment 2 possesses the property that, after the U-shaped double-layer portion 54 is deformed by applying an external force to, for example, the external force, in a manner that opens in the direction of pulling apart the first strip portion 55 and the second strip portion 57, the double-layer portion 54 can return to its shape before deformation when the external force is removed. Furthermore, in this embodiment 2, the restored "shape before deformation" includes both the same shape as before deformation and shapes close to the same shape (approximately the same shape). Additionally, heat treatment refers to a process that includes heating the object being processed.

[0108] By giving the double-layer portion 54 of this embodiment the aforementioned properties, if no external force is applied to the double-layer portion 54, the double-layer portion 54 can easily maintain its U-shaped form, thus preventing the zipper tape 22 from being exposed to the outside between the zipper teeth 23 and the component 10 on which the zipper is to be installed. Furthermore, even if a portion of the second strip portion 57 is temporarily separated from the zipper tape 22 due to the application of external force to the double-layer portion 54, or if the double-layer portion 54 is separated from the zipper tape 22 and rolled up, since the shape of the double-layer portion 54 can return to its original U-shaped form after the external force is removed, the double-layer portion 54 can cover the zipper tape 22 again, preventing the zipper tape 22 from being exposed to the outside.

[0109] Furthermore, in this embodiment 2, creases can be formed by applying heat and pressure to the bent portion 56 of the double-layer portion 54, such as through ironing. By forming such creases in the bent portion 56, the bent shape of the double-layer portion 54 (in other words, the U-shaped shape of the double-layer portion 54) can be made more stable. Moreover, in this embodiment 2, a membrane or other component for easily maintaining the shape of the double-layer portion 54 can be installed on the inner side of the double-layer portion 54. This also makes the bent shape of the double-layer portion 54 more stable.

[0110] In this embodiment 2, the sewn part 12, which sews the zipper toothed belt mounting edge 51 to the zipper toothed belt 21, is arranged in a straight line along the front-back direction of the zipper belt 22 by using a flat sewing process of a sewing machine. Using this sewn part 12, the zipper toothed belt 21 is fixed to the zipper toothed belt mounting edge 51 of the fabric 50. Furthermore, a portion of the sewn part 12 is configured to be sandwiched between the first strip portion 55 and the second strip portion 57 of the double-layer portion 54.

[0111] In this embodiment 2, the sewn portion 12 is positioned in the left-right direction at a position separated from the outer side (inner side) of the zipper tooth 23 in the left-right direction, and is also positioned in the left-right direction separated from the outer side of the bent portion 56 of the zipper belt mounting edge 51. In this case, the left-right separation distance D1 between the sewn portion 12 and the wing portion 23b of the zipper tooth 23 is preferably 1.0 mm or more and 10.0 mm or less. At this time, the bent portion 56 of the zipper belt mounting edge 51 is disposed in contact with the zipper tooth 23, and in the left-right direction, the portion of the double-layer portion 54 between the position of the sewn portion 12 and the position of the bent portion 56 is formed as a wing on the zipper belt 22. As a result, a water-resistant area is formed between the sewn portion 12 and the zipper tooth 23.

[0112] Next, the method for manufacturing the zippered product 2 of this embodiment 2 will be briefly described.

[0113] First, a sewing process is performed using a sewing machine to sew together the zipper strap 22 of the zipper chain strap 21 and the mounting edge 51 of the zipper chain strap on the fabric 50. After this sewing process, a bending process is performed to bend the mounting edge 51 of the zipper chain strap on the fabric 50 to form a double-layered portion 54. Furthermore, the sewing and bending processes in this embodiment 2 are performed in essentially the same way as the sewing and bending processes described in the aforementioned embodiment 1.

[0114] Next, a heat treatment process is performed, in which the toothed chain mounting edge 51 and the zipper toothed chain 21, which have formed a double-layered portion 54 by the bending process, are subjected to heat treatment to stabilize the shape of the toothed chain mounting edge 51.

[0115] In the heat treatment process of this embodiment 2, a heat treatment (heat setting treatment) is performed on the double-layer portion 54 of the toothed chain mounting edge 51 while it is bent into a U-shape. As a result, the shape of the double-layer portion 54 after bending can be stabilized, so that, for example, if the double-layer portion 54 is deformed by an external force and that external force is removed, the double-layer portion 54 can be restored to its original shape before deformation.

[0116] Furthermore, in the heat treatment process of this embodiment 2, as heat treatment, for example, an iron can be used to perform an ironing process where the double-layer portion 54, which is bent into a U-shape by pressing the mounting edge 51 of the chain strap, is heated while the double-layer portion 54 is heated. By performing such an ironing process, the aforementioned creases can be easily formed at the bent portion 56 of the double-layer portion 54.

[0117] That is, in this embodiment 2, by performing heat treatment processes including the heat setting treatment or ironing process described above, a double-layered portion 54 with the property of maintaining the bent shape of the bent portion 56 can be stably formed on the toothed belt mounting edge 51 of the fabric 50. Furthermore, in this invention, the heat treatment process for maintaining the bent shape is not limited to the heat setting treatment and ironing process described above; other treatments and processes involving heating may also be included in the heat treatment process.

[0118] By performing the above-mentioned sewing, bending, and heat treatment processes, a product is produced. Figure 7 The fabric 50 has the zipper toothed chain 21 sewn onto the toothed chain mounting edge 51 as shown. At this time, the sewn part 12 that sews the zipper toothed chain 21 to the toothed chain mounting edge 51 is covered by the toothed chain mounting edge 51 (especially the first strip part 55).

[0119] Furthermore, in this embodiment 2, the sewing process, bending process, and heat treatment process are performed sequentially as described above. However, in this invention, the order in which the sewing process, bending process, and heat treatment process are performed is not particularly limited; for example, the bending process and heat treatment process may be performed before the sewing process.

[0120] Then, by using the fabric 50 with the zipper teeth 21 sewn on it in this embodiment 2, the zippered garment 2 can be manufactured in the same way as in the case of the aforementioned embodiment 1.

[0121] In the zippered garment 2 of this embodiment 2 manufactured in this way, although the sewing part 12 is provided separately from the zipper teeth 23 in the left and right direction, the double-layer part 54 of the tooth belt mounting edge part 51 is stabilized in shape by performing heat treatment (heat treatment process), thereby forming a shape that can maintain the bent shape of the bending part 56.

[0122] Therefore, according to the zippered garment of this embodiment 2, the double-layer portion 54 of the zipper tooth mounting edge 51 is less likely to roll up relative to the zipper tooth 21, and the double-layer portion 54 can be easily kept in contact (or close to) the zipper tooth 23.

[0123] Therefore, in this embodiment 2, it is possible to prevent or suppress the zipper tape 22 from being exposed to the outside between the zipper teeth 23 and the component 50 on which the zipper is to be installed, and it is easy to cover the zipper tape 22 almost entirely using the toothed tape mounting edge 51. Thus, it is possible to prevent or suppress damage to the design and appearance quality of the garment due to the exposure of the zipper tape 22.

[0124] Furthermore, in the zippered garment of this embodiment 2, similar to the case of the aforementioned embodiment 1, even if the zipper tape 22 itself is not water-resistant, as long as the fabric 50 of the garment is at least water-resistant, liquid can be prevented from easily seeping in through the zipper 20.

[0125] [Example 3]

[0126] Figure 8 This is a cross-sectional view schematically showing a portion of the zippered product of this embodiment 3, orthogonal to the front-back direction.

[0127] The zippered product 3 of this embodiment 3 is, like the aforementioned embodiment 1, clothing. The zippered clothing 3 of this embodiment 3 includes: a zipper 20 having a pair of left and right zipper teeth 21; and a component (fabric) 70 for mounting the zipper, having left and right tooth mounting edges 71 for mounting the left and right zipper teeth 21.

[0128] The zippered garment 3 of this embodiment differs from the zippered garment 1 described in Embodiment 1 in the following three aspects. Firstly, the zippered garment 3 of this embodiment 3 does not have the first adhesive layer 31 and the second adhesive layer 32 described in Embodiment 1. Secondly, in the zippered garment 3 of this embodiment 3, the setting range of the lateral separation distance between the sewn portion 12 and the wing portion 23b of the zipper tooth 23 differs from that of Embodiment 1. Thirdly, in the zippered garment 3 of this embodiment 3, the thickness T of the double-layer portion 74 is set to a size within a specified range. Furthermore, apart from the above three points, the zippered garment 3 of this embodiment 3 is formed substantially the same as the zippered garment 1 described in Embodiment 1.

[0129] In this embodiment 3, the left and right fabrics 70 of the garment are at least water-resistant. Each left and right fabric 70 has a main fabric portion (not shown) and a toothed chain strap mounting edge portion 71 provided at the end edge of the main fabric portion. The toothed chain strap mounting edge portion 71 of each fabric 70 has a double-layer portion 74 in which the fabrics 70 of the garment overlap in the vertical direction to form a letter U-shape.

[0130] In this embodiment 3, the double-layer portion 74, when viewed in cross-section orthogonal to the front-back direction, comprises: a first strip portion 75 extending inward from the main fabric portion (not shown) in the width direction; a bending portion 76 extending from the first strip portion 75 while bending; and a second strip portion 77 extending from the bending portion 76 and overlapping the first strip portion 75. A zipper tooth strip 21 is mounted on the second strip portion 77 of the double-layer portion 74 using a sewing portion 12. Furthermore, the double-layer portion 74 is formed in contact with the wing portion 23b (second wing portion 25b) of the zipper tooth 23.

[0131] In this embodiment 3, the thickness T of the double-layer portion 74 of the toothed chain belt mounting edge 71 is set to be 0.25 mm or more and 5.0 mm or less. In this case, the thickness T of the double-layer portion 74 is the vertical dimension from the position of the upper surface (outer surface) of the first belt portion 75 to the position of the lower surface (outer surface) of the second belt portion 77.

[0132] By making the thickness T of the double-layer portion 74 0.25 mm or more, preferably 0.55 mm or more, the double-layer portion 74 can be easily formed closer to the zipper teeth 23, thus easily maintaining the contact state between the double-layer portion 74 and the zipper teeth 23 (especially the wing portion 23b). This prevents or suppresses the zipper tape 22 from being exposed between the double-layer portion 74 and the zipper teeth 23. Furthermore, even if the double-layer portion 74 slightly separates from the zipper teeth 23 due to external forces, by making the double-layer portion 74 thicker in the vertical direction as described above, the portion between the zipper teeth 23 and the double-layer portion 74 is easily hidden in the shadow of the double-layer portion 74, thus making it difficult to see the zipper tape 22 through the gap between the zipper teeth 23 and the double-layer portion 74.

[0133] In addition, by making the thickness T of the double-layer portion 74 5.0 mm or less, preferably 3.0 mm or less, the step between the toothed belt mounting edge portion 71 and the zipper tooth 23 can be reduced, preventing the reduction of waterproof performance caused by water droplets remaining on the step when they adhere.

[0134] Additionally, it is also considered to set the thickness T of the double-layer portion 74 to be the same thickness as the wing portion 23b of the zipper tooth 23. Figure 8In the middle, the wing portion 23b is formed into a wedge shape in which the thickness decreases from the outer side (inner side) of the zipper tooth 23 in the left and right direction. However, in order to avoid forming a step or reduce the step between the wing portion 23b and the double layer portion 74, the wedge shape of the wing portion 23b may be removed, or the wedge-shaped area of ​​the wing portion 23b may be formed to be smaller.

[0135] In this embodiment 3, the sewn part 12, which sews the zipper toothed belt mounting edge 71 to the zipper toothed belt 21, is arranged in a straight line along the front-back direction of the zipper belt 22 by using a flat sewing process of a sewing machine. Using this sewn part 12, the zipper toothed belt 21 is fixed to the zipper toothed belt mounting edge 71 (second belt portion 77) of the fabric 70. Furthermore, a portion of the sewn part 12 is configured to be sandwiched between the first belt portion 75 and the second belt portion 77 of the double-layer portion 74.

[0136] In this embodiment 3, the sewn portion 12 is positioned in the left-right direction at a position separated from the outer side (inner side) of the zipper tooth 23 in the left-right direction, and is also positioned in the left-right direction separated from the outer side of the bent portion 76 of the zipper tooth mounting edge 71. In this case, the separation distance D2 in the left-right direction between the sewn portion 12 and the wing portion 23b of the zipper tooth 23 is preferably 0.5 mm or more and 10.0 mm or less. At this time, the bent portion 76 of the zipper tooth mounting edge 71 is disposed in contact with the zipper tooth 23, and in the left-right direction, the portion of the double layer 74 between the position of the sewn portion 12 and the position of the bent portion 76 is formed as a wing on the zipper tape 22. As a result, a water-resistant area is formed between the sewn portion 12 and the zipper tooth 23.

[0137] By making the separation distance D2 0.5 mm or more, preferably 0.8 mm or more, when forming the sewing part 12 using a sewing machine, it is not easy for the sewing machine needle to come into contact with the zipper teeth 23, and the sewing process of sewing the zipper tape 22 to the toothed zipper tape mounting edge 71 of the fabric 70 can be carried out smoothly and stably.

[0138] Furthermore, by making the aforementioned separation distance D2 10.0 mm or less, preferably 5.0 mm or less, it is possible to prevent the double-layer portion 74 from curling up. Therefore, the zipper tape 22 is less likely to be visible between the zipper teeth 23 and the double-layer portion 74. Moreover, by making the aforementioned separation distance D2 10.0 mm or less, it is possible to prevent the width dimensions of the zipper tape 22 and the second tape portion 77 from becoming excessively large, making it easier to reduce manufacturing costs. When the separation distance is greater than 10.0 mm, it is sometimes difficult to position and bend the tape so that the bent portion 76 contacts the zipper teeth 23.

[0139] In the zippered garment 3 of this embodiment 3 described above, although the sewn part 12 is separated from the zipper teeth 23 in the left-right direction, by making the thickness T of the double-layer part 74 0.25 mm or more, and narrowing the separation distance D2 between the sewn part 12 and the zipper teeth 23 to 10.0 mm or less, the double-layer part 74 of the toothed zipper tape mounting edge 71 is less likely to roll up relative to the zipper toothed zipper tape 21, and the zipper tape 22 is less likely to be seen between the zipper teeth 23 and the double-layer part 74. Therefore, it is possible to prevent or suppress damage to the design and appearance quality of the garment due to the exposure of the zipper tape 22.

[0140] Furthermore, in the zippered garment 3 of this embodiment 3, similar to the case of the aforementioned embodiment 1, even if the zipper tape 22 itself is not water-resistant, as long as the fabric 70 of the garment is at least water-resistant, liquid can be prevented from easily seeping in through the zipper 20.

[0141] Furthermore, in the zippered garment of this embodiment 3, it is also possible to satisfy either the condition that the thickness T of the double-layer portion 74 is 0.25 mm or more, or the condition that the lateral separation distance D2 between the sewn portion 12 and the wing portion 23b of the zipper tooth 23 is 10.0 mm or less. In this way, even if only one condition is met, the zipper strap will not be easily visible from the outside of the zippered garment.

[0142] [Example 4]

[0143] Figure 9 This is a cross-sectional view schematically showing a portion of the zippered product of this embodiment 4, orthogonal to the front-back direction.

[0144] The zippered product 4 of this embodiment 4 is, like the aforementioned embodiment 1, clothing. The zippered clothing 4 of this embodiment 4 includes: a zipper 20 having a pair of left and right zipper teeth 21; and a component (fabric) 90 for mounting the zipper, having left and right tooth zipper mounting edges 91 for mounting the left and right zipper teeth 21.

[0145] The zippered garment 4 of this embodiment 4 differs from the zippered garment 1 described in Embodiment 1 in the following three aspects. Firstly, the first adhesive layer 31 and the second adhesive layer 32 described in Embodiment 1 are not provided on the zippered garment 4 of this embodiment 4. Secondly, the bending portion 96 is positioned in the left-right direction close to the formation position of the sewing portion 12 and close to the zipper tooth 23. Thirdly, in the zippered garment 4 of this embodiment 4, the range of the separation distance in the left-right direction between the sewing portion 12 and the wing portion 23b of the zipper tooth 23 is different from that in Embodiment 1. Furthermore, apart from the above three points, the zippered garment 4 of this embodiment 4 is formed substantially the same as the zippered garment 1 described in Embodiment 1.

[0146] In this embodiment 4, the left and right fabrics 90 of the garment are at least water-resistant. Each left and right fabric 90 has a main fabric portion (not shown) and a toothed chain strap mounting edge portion 91 provided at the end edge of the main fabric portion. The toothed chain strap mounting edge portion 91 of each fabric 90 has a double-layer portion 94 in which the fabrics 90 of the garment overlap in the vertical direction to form a letter U-shape.

[0147] In this embodiment 4, the double-layer portion 94, when viewed in cross-section orthogonal to the front-back direction, comprises: a first strip portion 95 extending inward from the main fabric portion (not shown) in the width direction; a bending portion 96 extending from the first strip portion 95 while bending; and a second strip portion 97 extending from the bending portion 96 and overlapping the first strip portion 95. A zipper tooth strip 21 is mounted on the second strip portion 97 of the double-layer portion 94 using a sewing portion 12. Furthermore, the double-layer portion 94 is formed in a state close to the wing portion 23b (second wing portion 25b) of the zipper tooth 23.

[0148] In this embodiment 4, the sewn part 12, which sews the zipper toothed belt mounting edge 91 to the zipper toothed belt 21, is arranged in a straight line along the front-back direction of the zipper belt 22 by using a flat sewing process of a sewing machine. Using this sewn part 12, the zipper toothed belt 21 is fixed to the zipper toothed belt mounting edge 91 (second belt portion 97) of the fabric 90. Furthermore, a portion of the sewn part 12 is configured to be sandwiched between the first belt portion 95 and the second belt portion 97 of the double-layer portion 94.

[0149] In this embodiment 4, the sewn portion 12 is positioned in the left-right direction at a position separated from the outer side (inner side) of the zipper teeth 23 in the left-right direction. In addition, by bending the toothed zipper tape mounting edge 91 with the sewn portion 12 as the starting point and overlapping the first tape portion 95 and the second tape portion 97 vertically to form a double-layer portion 94, the bent portion 96 is formed at a position close to the sewn portion 12.

[0150] In this case, the lateral separation distance D3 between the sewn portion 12 and the wing portion 23b of the zipper tooth 23 is preferably 3.0 mm or less. More preferably, the separation distance D3 is 2.0 mm or less or 1.0 mm or less. Furthermore, the separation distance D3 is preferably 0.5 mm or more. In other words, the separation distance D3 is preferably 60% or less of the lateral width of the zipper tooth 23 (here referring to the width of the portion excluding the width of the first wing and the width of the second wing). More preferably, the separation distance D3 is 40% or less or 20% or less of the lateral width of the portion of the zipper tooth 23 excluding the wing. Furthermore, the separation distance D3 is preferably 10% or more of the lateral width of the portion of the zipper tooth 23 excluding the wing. In Example 4, unlike Examples 1-3, although no flap is formed between the position of the sewn part 12 and the position of the bent part 96, a water-resistant area is formed between the sewn part 12 and the zipper tooth 23 by setting the separation distance D3 to a narrow width (making it smaller).

[0151] By making the aforementioned separation distance D3 0.5 mm or more, or 10% or more of the width of the zipper tooth 23 in the left and right directions excluding the wing portion, when forming the sewing part 12 using a sewing machine, it is not easy for the sewing machine needle to come into contact with the zipper tooth 23, and the sewing process of sewing the zipper tape 22 to the toothed edge 71 of the fabric 70 can be carried out smoothly and stably.

[0152] In addition, by making the aforementioned separation distance D3 less than 3.0 mm, or less than 60% of the width of the zipper tooth 23 in the left and right directions excluding the wing portion, it is not easy to see the zipper tape 22 between the zipper tooth 23 and the double layer portion 94.

[0153] In the zippered garment 4 of this embodiment 4 described above, although the sewing portion 12 is separated from the zipper teeth 23 in the left-right direction, by setting the separation distance D3 between the sewing portion 12 and the zipper teeth 23 to a narrow width of 3.0 mm or less, the zipper tape 22 is not easily visible between the zipper teeth 23 and the double-layer portion 94. Therefore, it is possible to prevent or suppress damage to the design and appearance quality of the garment due to the exposure of the zipper tape 22.

[0154] Furthermore, in the zippered garment 4 of this embodiment 4, similar to the case of the aforementioned embodiment 1, even if the zipper tape 22 itself is not water-resistant, as long as the fabric 90 of the garment is at least water-resistant, the aforementioned water-resistant area can be used to prevent liquid from easily seeping in through the zipper 20.

[0155] Furthermore, regarding each of Examples 1 to 4, a water-resistant area was confirmed to be formed between the sewn part 12 and the zipper tooth 23 through a rain test described below. The rain test was conducted under rain conditions (24 in, 2 min) applicable to AATCC 35. In addition, to eliminate the influence of water leakage from the gap of the zipper tooth 23, a water-proof tape was attached to the front surface of the zipper tooth 23 for testing. The results of the rain test confirmed that the water permeability in each water-resistant area of ​​Examples 1 to 4 was less than 0.1 g.

[0156] Furthermore, the present invention is not limited to the embodiments 1 to 4 described above. Various modifications can be made as long as the structure is substantially the same as that of the present invention and the same effect is achieved.

[0157] For example, in Embodiments 1 to 4, as described above, the zipper teeth 23 are individually formed in shape on the zipper tape 22 by injection molding of synthetic resin, thereby forming the zipper 20 and the zipper tooth tape 21. However, in this invention, instead of the synthetic resin zipper teeth 23, multiple metal zipper teeth formed in their own shapes can be provided on the zipper tape, thereby forming the zipper and the zipper tooth tape.

[0158] Furthermore, in Examples 1 to 4, the zippered garments were described as having at least water resistance; however, in this invention, zippered garments may not be water-resistant. Also, while this embodiment described garments as representative examples of products with zippers, in this invention, zippered products are not limited to garments. Zippered products of this invention include various products other than garments, such as clothing, footwear, bags, and other daily necessities; industrial materials; and various sheet materials used in automobiles, trains, aircraft, etc.
