Description

Hidden zipper semi-finished product, concealed zipper installation product and method for manufacturing concealed zipper installation product

The invention relates to a semi-finished concealed zipper product, a concealed zipper installation product and a concealed zipper installation product manufacturing method.

In the prior art of a nylon zipper, a coil-shaped element is usually sewn directly on a pair of butt portions where the zipper tape is separated from the middle, and then a zipper chain including the zipper tape and the element is sewn on the fabric . At this time, on the inner surface of the fastener tape (the surface on the side where the coil-shaped element is not arranged), small irregularities formed by the sewing thread when sewing the element appear. In addition, in order to prevent the fastener element of the nylon zipper from being seen from the surface of the fabric, the slider of the slider may be provided on the surface opposite to the belt surface on which the fastener element is arranged and used. This is called internal use of the fastener.

Patent Document 1 of the prior art describes that a nylon zipper tape is not sewn except for using a nylon zipper for internal use, but is adhered and installed on a fabric by an adhesive (see FIGS. 3 and 4 of Patent Document 1). Example). Moreover, recently, for the purpose of lightweighting clothes, there is a tendency to thin fabric blanks. Here, if the zipper used internally is attached to a thin blank fabric by adhesion as described in Patent Document 1, the unevenness of the sewing thread on the inner surface of the zipper chain described at the beginning will not be thinned by the fabric The blank is absorbed, and the surface of the fabric causes irregularities, which affects the appearance of the finished zipper installation (clothing). Furthermore, another problem at this time is that a slider must be prepared for each different thickness of the blank according to the thickness of the blank of the fabric. That is, when the slider for opening or closing the fastener element is installed on the zipper chain, the fastener element and the fastener tape must be inserted into the slider together with the sewn fabric (as described in FIG. 10 of Patent Document 1 ). In this way, when the slider slides relative to the zipper chain, the slider also needs to pass through the fabric. If the size of the slider passing portion of the slider is not appropriate, the slider sliding relative to the zipper chain is not smooth due to the thickness of the fabric, and the fabric is also prone to slide marks or damage.

In addition, Patent Document 1 also describes that a waterproof coating (fabric) is adhered to and attached to a concealed slide fastener (refer to the related description of FIGS. 2, 9 a, and 9 b of Patent Document 1 ). However, as described in the conventional concealed slide fastener in Patent Document 1, Patent Document 1 also has the problems described below. That is, generally, the waterproof coating layer and its adhesive layer are cut into a shape conforming to a pair of left and right zipper tapes, and the cut pieces are respectively attached to the pair of left and right zipper tapes. During the attachment, the slider It can move on a pair of left and right zipper tapes to adjust the width appropriately, so it consumes cost and time in processing.

FIG. 1 is a schematic diagram of a concealed zipper semi-finished product 100 according to the first embodiment of the present invention. The above-mentioned semi-finished product means that although the zipper which is a complete product is not completed, it can be directly circulated on the market as a sales item. Specifically, the hidden zipper semi-finished product 100 is not equipped with a slider. FIG. 2 is a schematic diagram of a concealed zipper installation product 50 obtained by applying the concealed zipper semi-finished product 100 of FIG. 1. In this embodiment, the concealed zipper semi-finished product 100 shown in FIG. 1 can be installed on the fabric 60, the middle partition is cut, and then the slider 130 is installed, thereby forming the concealed zipper installation product 50 shown in FIG. 2, But not limited to this purpose.

In addition, the fabric 60 of the present invention includes, of course, cloths and knitted fabrics, but is not limited to this, and widely includes blanks or other materials used in clothes or bags, blanks or non-woven fabrics or resins used in rain coats The blanks such as sheets or their laminated parts are defined in terms.

First, the concealed zipper semi-finished product 100 of this embodiment will be described. As shown in FIG. 1, the concealed zipper semi-finished product 100 includes a pair of zipper chains 110 and an adhesive layer 120. The zipper chain 110 has a pair of zipper tapes 112 and fastener elements 114. The fastener element 114 is disposed on the inner surface 112a of the fastener tape 112, and the adhesive layer 120 is disposed on the outer surface 112b of the fastener tape 112.

In detail, in the present embodiment, the zipper tape 112 is a long strip-shaped structure, and the pair of zipper tapes 112 also has a pair of folded-back portions 112c separated from the middle. The zipper tape 112 of this embodiment is further bent at the inside of the inner surface 112a at the folded portion 112c to form an edge portion 112d extending and folded back to the inner surface 112a, that is, the zipper tape 112 has a pair of faces toward the inner surface 112a U-shaped bent edge 112d. The fastener element 114 is disposed on the edge portion 112d, and accordingly is away from the adhesive layer 120 disposed on the outer surface 112b.

On the other hand, the fastener element 114 in this embodiment is a coil-shaped fastener element, that is, the fastener element 114 assumes a coil shape and is disposed on the inner surface 112a of the fastener tape 112 without being exposed from the outer surface 112b of the fastener tape 112 Out. In this way, the coil-shaped element as the element 114 is sewn by the sewing thread 150 and attached to the edge portion 112d bent inward.

Specifically, in the general zipper technology, the fastener element is usually sewn directly on the butt portion on the zipper tape. In the seamless joining technology, for example, the zipper chain is attached to the fabric through the adhesive layer, and the sewing thread sewing the fastener element on the zipper tape will cause the unevenness of the fabric. In contrast, in this embodiment, the fastener element 114 is sewn to the edge 112d bent in a U-shape on the fastener tape 112, so that the fastener element 114 and the sewing thread 150 are located on the inner surface 112a of the fastener tape 112 and away from the outside The adhesive layer 120 of 112b. In this way, the sewing thread 150 does not pass through the outer surface 112b of the zipper tape 112, and the adhesive layer 120 can be more evenly arranged on the outer surface 112b of the zipper tape 112, that is, the sewing thread 150 does not interfere with the setting of the adhesive layer 120. Also, in the case where the concealed zipper semi-finished product 100 is attached to the inner surface 60a of the fabric 60 with the adhesive layer 120 as shown in FIG. 2, the sewing thread 150 is positioned on the inwardly bent edge portion 112d, even if a thin or transparent The light material is used as the fabric 60, and it is difficult to perceive the presence of the sewing thread 150 from the outside of the fabric 60 through vision.

As shown in FIG. 1, the adhesive layer 120 is attached to the outer surface 112 b of the pair of zipper tapes 112 as a sheet member. That is, the adhesive layer 120 is continuously attached to the outer surface 112b of the pair of zipper tapes 112. Thereby, the adhesive layer 120 is attached so as to cover a portion where the folded-back portions 112c of the pair of zipper chains 110 are in contact with each other while the pair of zipper chains 110 are engaged. That is, even if the pair of fastener tapes 112 are separated from the folded portion 112c, the relative position of the pair of fastener tapes 112 is fixed through the adhesive layer 120.

Furthermore, in the case where the concealed zipper semi-finished product 100 has not been used, the adhesive layer 120 as a sheet-like member is protected or does not have adhesiveness. The protection of the adhesive layer 120 means that the adhesive layer 120 includes an adhesive material disposed on the outer surface 112b of the zipper tape 112 and a release paper covering the adhesive material, and is used as the adhesive layer 120 when the hidden zipper semi-finished product 100 has not been used. The material is protected by release paper. On the other hand, the fact that the adhesive layer 120 does not have adhesiveness means that the adhesive layer 120 includes a hot-melt adhesive material disposed on the outer surface 112b of the zipper tape 112, and is used as the adhesive layer 120 when the hidden zipper semi-finished product 100 has not been used. The hot melt adhesive material does not have adhesion at room temperature. With this, when the concealed zipper semi-finished product 100 can be circulated on the market as a sale item, it is possible to avoid unintended adhesion or reduce adhesion. It can be seen that the present invention does not limit the implementation of the adhesive layer 120, which can be adjusted according to requirements.

As shown in FIG. 2, the concealed zipper installation product 50 includes a fabric 60, a concealed zipper semi-finished product 100, a slider 130 and an upper plate member 140. The fabric 60 has a cut-out middle partition 62, and the concealed zipper semi-finished product 100 is attached to the inner surface 60a of the fabric 60 by an adhesive layer 120. In addition, the slider 130 of the switch-operated fastener chain 110 is attached to the fastener element 114 and is located on the inner surface 112 a of the fastener tape 112, and the upper plate member 140 connected to the slider 130 is located on the outer surface 112 b of the fastener tape 112. In this way, when the concealed zipper semi-finished product 100 is attached to the inner surface 60a of the fabric 60 by the adhesive layer 120, the zipper chain 110, the adhesive layer 120, and the slider 130 are located on the inner surface 60a of the fabric 60, and the upper plate member 140 is worn It is located on the outer surface 60b of the fabric 60 through the middle partition 62 on the fabric 60, so that the fabric 60 is located between the slider 130 and the upper plate member 140.

In detail, in this embodiment, since the fastener element 114 is sewn to the edge portion 112d bent in a U-shape on the fastener tape 112, the slider 130 attached to the fastener element 114 is also attached to the edge portion 112d. Therefore, the slider 130 penetrates the edge portion 112d and the fastener element 114 of the fastener tape 112 from one end of the fastener chain 110, and further surrounds the edge portion 112d and the fastener element 114 of the fastener tape 112. In this way, by driving the upper plate member 140 positioned on the outer surface 60b of the fabric 60, the slider 130 can slide on the fastener element 114, thereby opening or closing the fastener element 114. At this time, the slider 130 passes through the element 112 and the edge 112d of the fastener tape 112, but does not pass through the fabric 60.

Furthermore, in this embodiment, the slider 130 and the upper plate member 140 are connected to each other, and may be attached to the zipper chain 110 together or may be removed from the zipper chain 110 together. During the installation of the slider 130 on the fastener element 114, the slider 130 penetrates the edge 112 d and the fastener element 114 from one end of the zipper chain 110 and is located on the inner surface 112 a of the zipper tape 112. In contrast, the upper plate member 140 is located on the outer surface 112b of the zipper tape 112.

Furthermore, the fabric 60 has a cut-out middle partition 62. The middle partition 62 is a cut open structure, and its length is preferably not more than the length of the zipper chain 110 (including the zipper tape 112 and the fastener element 114), so as to reduce the exposed end of the zipper chain 110 through the middle partition 62 possibility. When the zipper chain 110 is attached to the inner surface 60a of the fabric 60 by the adhesive layer 120, the zipper chain 110, the adhesive layer 120 and the slider 130 are located on the inner surface 60a of the fabric 60, and the upper plate member 140 passes through the fabric 60 The middle partition 62 is located on the outer surface 60b of the fabric 60. In this way, in the hidden zipper installation finished product 50, the hidden zipper semi-finished product 100 (including the zipper chain 110 and the adhesive layer 120) and the slider 130 are hidden on the inner surface 60a of the fabric 60, and only the upper plate member 140 is located on the outer surface 60b of the fabric 60 , So that the slider 130 slides on the zipper chain 110 by pulling or pushing the upper plate member 140.

It can be seen that the concealed zipper semi-finished product 100 of this embodiment can be used as an independent product, and is further applied to the fabric 60 to constitute the concealed zipper installation product 50. The fabric 60 may be, for example, a fabric of a jacket. After cutting and sewing, the concealed zipper semi-finished product 100 is combined to form the concealed zipper installation product 50 (for example, a jacket), but the present invention is not limited thereto. The process of installing the concealed zipper semi-finished product 100 on the inner surface 60a of the fabric 60 to form the concealed zipper installation product 50, that is, the steps of the method for manufacturing the concealed zipper installation product 50 can be referred to FIGS. 3A to 3D and the following description.

FIGS. 3A to 3D are schematic diagrams illustrating states in each flow in the manufacturing method of the concealed slide fastener mounting product 50 obtained by applying the concealed slide fastener semi-finished product 100 of FIG. 1. First, as shown in FIG. 3A, the procedure for preparing the concealed slide fastener semi-finished product 100 will be described. The concealed zipper semi-finished product 100 is an article with an adhesive layer 120 installed on the zipper chain 110 in the engaged state, but the slider 130 is not installed.

Next, as shown in FIG. 3B, the step of attaching the zipper chain 110 of the concealed zipper semi-finished product 100 to the inner surface 60a of the fabric 60 through the adhesive layer 120 will be described. In detail, when the hidden zipper semi-finished product 100 has not been used, that is, it has not been installed in front of the fabric, as described above, the adhesive layer 120 is protected or does not have adhesiveness. In the step of attaching the zipper chain 110 of the concealed zipper semi-finished product 100 to the inner surface 60a of the fabric 60 by the adhesive layer 120, the protection of the adhesive layer 120 is released, or the adhesive layer 120 is made to be adhesive, and then adhered The layer 120 adheres the zipper chain 110 to the inner surface 60a of the fabric 60 in such a manner as to face the inner surface 60a of the fabric 60. For example, by removing the release paper to release the protection of the adhesive layer 120, the zipper chain 110 can be adhered to the inner surface 60a of the fabric 60 by the adhesive material as the adhesive layer 120. Alternatively, after the zipper chain 110 is disposed on the inner surface 60a of the fabric 60 with the adhesive layer 120 facing the fabric 60, the adhesive layer 120 is heated (for example, the fabric 60 or the zipper tape 112 is heated by a heating device such as an iron, indirectly When the adhesive layer 120 is heated, the hot-melt adhesive material can be made to adhere, and the zipper chain 110 can be adhered to the inner surface 60a of the fabric 60 by the hot-melt adhesive material as the adhesive layer 120. Through this step, the zipper chain 110 can be installed on the inner surface 60a of the fabric 60 without sewing. Furthermore, the zipper chain 110 is adhered to the inner surface 60a of the fabric 60.

Moreover, in the step of attaching the zipper chain 110 to the inner surface 60a of the fabric 60 by the adhesive layer 120, most of the zipper tape 112 of the zipper chain 110 is adhered to the inner surface 60a by the adhesive layer 120, but the zipper chain 110 At least one end (not shown) has not been pasted to the inner surface 60a. In this way, the slider 130 can be attached to the fastener element 114 from the end portion of the zipper tape 112 that has not been adhered in a subsequent step.

Next, please refer to FIG. 3C to explain the step of cutting the middle partition 62 of the fabric 60 corresponding to the portion where the folded portions of the zipper chain 110 are in contact with each other. The middle partition 62 is cut by a laser, but it is not limited to this, and it may be cut by a blade, for example. If the zipper chain 110 is adhered to the inner surface 60a of the fabric 60 by the adhesive layer 120 and then the middle partition 62 of the zipper chain 110 is cut from the outside on the fabric 60, the cut middle partition 62 can be made by the adhesive layer 120 is tightly engaged with the zipper tape 112. That is, when the zipper tape 112 has been adhered to the inner surface 60a of the fabric 60 by the adhesive layer 120, when the middle partition 62 of the fabric 60 is cut from the outside, the adhesive layer 120 is also cut so that the edge of the middle partition 62 Still through the adhesive layer 120 and the butt portion of the zipper tape 112 are tightly joined together, it is possible to reduce the possibility that the middle partition 62 is separated from the zipper tape 112 and the zipper tape 112 is exposed from the outside of the fabric 60.

In other embodiments not shown, the above steps can also be reversed, that is, the middle partition 62 is cut on the fabric 60, and then the zipper chain 110 is installed on the fabric by the adhesive layer 120 corresponding to the position of the middle partition 62 60的内面60a. However, compared to the step of first installing the zipper chain 110 on the fabric 60 after cutting the middle partition 62 on the fabric 60, the step of cutting the middle partition 62 on the fabric 60 after installing the zipper chain 110 on the fabric 60 The positioning operation of the zipper chain 110 corresponding to the cut middle partition 62 may be omitted, that is, it has a relatively simple installation method, but the invention is not limited thereto.

Finally, please refer to FIG. 3D to describe the steps of installing the slider 130 and the upper plate member 140 connected to each other on the zipper chain 110. Furthermore, although this embodiment takes the upper plate member 140 as an operation member of the slider 130 for example, the upper plate member 140 is not an essential component for the operation member of the slider 130, and can also be obtained by A component called a normal pull tab or rope (not shown) operates the slider 130.

In detail, the slider 130 and the upper plate member 140 are connected to each other, and can be removed from the zipper chain 110 together or attached to the zipper chain 110 together. When the slider 130 is attached to the zipper chain 110 together with the upper plate member 140, the slider 130 can be installed from the end of the zipper tape 112 that has not been adhered to the end of the fastener element 114 on the inner surface 60a of the fabric 60 The plate member 140 passes through the folded-back portion 112c of the fastener tape 112, the cut portion of the adhesive layer 120, and the cut-out middle partition 62 of the fabric 60, and is located on the outer surface 60b of the fabric 60. Moreover, after the step of attaching the slider 130 and the upper plate member 140 connected to each other to the zipper chain 110 through the unadhered end, the end of the zipper chain 110 can be adhered to the inner surface 60a of the fabric 60 through the adhesive layer 120 . At this time, the entire zipper chain 110 is adhered to the inner surface 60a of the fabric 60.

Through the above steps in the manufacturing method of the concealed zipper installation product 50 proposed in this embodiment, a concealed zipper installation product 50 can be obtained, which includes the aforementioned concealed zipper semi-finished product 100, slider 130, upper plate member 140 and Fabric 60. In the concealed zipper installation finished product 50, the concealed zipper semi-finished product 100 (including the zipper chain 110 and the adhesive layer 120) and the slider 130 are located on the inner surface 60a of the fabric 60, and only the upper plate member 140 is located on the outer surface 60b of the fabric 60, that is, The hidden zipper semi-finished product 100 and the slider 130 are hidden on the inner surface 60a of the fabric 60, and only the upper plate member 140 is exposed to the outer surface 60b of the fabric 60. In addition, in the case where the slider 130 or the rope (not shown) is used to operate the slider 130 instead of the upper plate member 140, the exposed portion on the outer surface 60 b of the fabric 60 can be reduced. In this way, the concealed slide fastener installation product 50 obtained by applying the concealed slide fastener semi-finished product 100 to the fabric 60 has a beautiful appearance.

In addition, since the upper plate member 140 is located on the outer surface 60b of the fabric 60, by pulling or pushing the upper plate member 140, the slider 130 can slide on the zipper chain 110 to open or close the fastener element 114. The pulling means that an unillustrated pull tab or rope is provided on the upper plate member 140 to pull the upper plate member 140 from the outside of the fabric 60 by the pull tab or the tie rope. The pushing means that an unillustrated finger recess is provided on the upper plate member 140 to push the upper plate member 140 through the finger recess from the outside of the fabric 60. In this way, the upper plate member 140 is pulled or pushed, so that the slider 130 slides on the element 114 of the zipper chain 110.

As shown in FIGS. 2 and 3D, after the slider 130 and the upper plate member 140 are attached to the zipper chain 110, the slider 130 is located on the inner surface 60a of the fabric 60, and the upper plate member 140 is located on the outer surface 60b of the fabric 60, so that the fabric 60 is located between the slider 130 and the upper plate member 140. In detail, in this embodiment, only the edge portion 112d of the fastener element 114 and the fastener tape 112 is inserted into the slider 130, and the fabric 60 is located in the space S1 between the slider 130 and the upper plate member 140 without being inserted into the slider 130. In this way, the sliding of the slider 130 on the fastener element 114 is not affected by the thickness of the fabric 60. In other words, there is an advantage that the thickness of the upper plate member 140 is adjusted according to the thickness of the fabric, and the gap between the upper plate member 140 and the slider 130 can be adjusted.

Furthermore, in the prior art in which both the fastener element and the fabric are inserted into the slider, the thickness of the fabric is limited by the internal height of the slider. That is, if the existing slider is applied to a thick fabric, the slider cannot easily slide on the fastener element and the fabric. In contrast, in the case of using this embodiment, the fabric 60 is located between the slider 130 and the upper plate member 140 without penetrating the slider 130, that is, the slider 130 does not pass through the fabric 60 during the sliding process. Therefore, when the slider 130 is driven to slide on the zipper chain 110 by the upper plate member 140 to open or close the fastener element 114, the slider 130 slides on the fastener element 114 without being affected by the thickness of the fabric 60. Moreover, since the slider 130 does not pass through the fabric 60 during the sliding process, the fabric 60 is not likely to cause sliding marks or damage due to the slider 130 sliding relative to the fastener element 114.

4A to 4C are a perspective view, a side view and a bottom view of the slider and upper plate member of FIG. 2. 4A to 4C, in this embodiment, the slider 130 and the upper plate member 140 are connected to each other, preferably as different components, and the upper plate member 140 is installed by the fixed portion 131 of the slider 130 . The fixing portion 131 of the slider 130 fixes the upper plate member 140 by caulking or engagement. In addition, the upper plate member 140 and the slider 130 may be integrally formed from the beginning. The upper plate member 140 includes a plate portion 142 connected to the slider 130 and a rib 144 protruding from the edge of the plate portion 142 toward the slider 130. As shown in FIG. 4B, the width w1 of the plate portion 142 is equal to the width w2 of the slider 130, and the rib 144 is located on the upper side of the slider 130 to face the slider 130. That is, the outer shape of the plate portion 142 and the outer shape of the slider 130 have substantially similar shapes and sizes, and the fabric 60 is located in the space S1 between the plate portion 142 of the upper plate member 140 and the slider 130, which is not easy because of the slider 130 slides relative to the fastener element 114 to cause sliding marks or damage.

In addition, as shown in FIG. 4C, the rib 144 surrounds the entire edge of the plate portion 142, but it may be only part of the edge disposed on the plate portion 142, and the present invention is not limited thereto. The rib 144 protrudes from the edge of the plate portion 142 toward the slider 130, that is, the vertical distance d2 of the rib 144 relative to the slider 130 is smaller than the vertical distance d1 of the plate portion 142 relative to the slider 130. When the concealed zipper semi-finished product 100 is attached to the fabric 60 shown in FIG. 2, the rib 144 protrudes from the edge of the plate portion 142 toward the fabric 60. As such, in the case where the fabric 60 is located in the space S1 between the plate portion 142 of the upper plate member 140 and the slider 130, the embodiment in which the rib 144 is provided can reduce the upper plate member 140 and the slider 130 viewed from the outside The gap between. However, in other embodiments not shown, the ribs 144 may also be omitted, so that the sliding of the upper plate member 140 and the slider 130 is smoother.

5A and 5B are a perspective view and a side view of a slider and an upper plate member of a second embodiment of the invention. In the second embodiment, the upper plate member 240 is made larger than the aforementioned upper plate member 140. In detail, the upper plate member 240 includes a plate portion 242 connected to the slider 130 and a rib 244 protruding from the edge of the plate portion 242 toward the slider 130. The width w3 of the plate portion 242 is greater than the width w2 of the slider 130. And the rib 244 is located outside the slider 230 and does not face each other with the slider 230. As such, the fabric 60 is located in the space S1 between the plate portion 242 of the upper plate member 240 and the slider 130, and it is not easy to cause sliding marks or damage due to the slider 130 sliding relative to the fastener element 114. Also, since the width w3 of the plate portion 242 of the upper plate member 240 is larger than the width w2 of the slider 130, the fabric 60 located in the space S1 between the upper plate member 240 and the slider 130 further faces the upper plate member 240 relative to the pull The space S2 below the head 130 on both sides. In this way, in the process of driving the slider 130 relative to the zipper chain 110 by the upper plate member 240, the resistance of the fabric 60 to the upper plate member 240 and the slider 130 is small, so that the upper plate member 240 and the slider 130 slide The movement is smoother.

However, in other embodiments, an upper plate member having no plate portion may be used. 6A and 6B are a perspective view and a side view of a slider and an upper plate member of a third embodiment of the invention. In the third embodiment, the upper plate member 340 is a connecting block connected to the slider 130 without the aforementioned plate portion and rib. In this way, when the upper plate member 340 with a smaller size is used, although the advantages brought by the plate portion and the ribs described above are not provided, by using the embodiment of the upper plate member 340 with a smaller size, the outer surface of the fabric can be reduced The exposed part can achieve the purpose of hiding the hidden zipper on the inner surface of the fabric. As described above, when the slider 130 is used instead of the upper plate member to operate the slider 130, the exposed portion on the outer surface of the fabric can be reduced, and the purpose of hiding the concealed zipper on the inner surface of the fabric can be more achieved.

The present invention is not limited to the above-mentioned embodiment, and can be appropriately modified without departing from the scope of the present invention. For example, the upper plate member may have a plate portion, but no ribs. Alternatively, the width of the plate portion may be smaller than the width of the slider. The connection method, relative distance, and respective size and shape of the upper plate component and the slider can be adjusted according to requirements. For example, the upper plate component may be made not limited to other shapes in the above drawings, or a specific pattern (such as a manufacturer's trademark) is provided on the surface of the upper plate component. In addition, the upper plate member may be in the aforementioned pull-tab form (with pull-tabs or ties) or without pull-tab form (with finger recesses), and the material and color of the upper-plate member may also be adjusted according to requirements. Furthermore, the upper plate component and the slider can also be detached from each other, and it is not limited to the need to be attached to or removed from the zipper chain together. In addition, although this embodiment is described by providing a set of sliders and upper plate members on the zipper chain, the concealed zipper including the concealed zipper semi-finished product 100 (including the concealed zipper semi-finished product 100 and the slider 130 is included) ) It can also be a double open end zipper, that is, two sets of sliders are provided on the zipper chain to open or close the fastener element from the opposite ends of the zipper chain. Alternatively, the above technical features can also be applied to other types of zipper chains, and the present invention is not limited thereto.

In summary, the semi-finished hidden zipper of the present invention has an adhesive layer provided on the zipper chain, and the semi-finished hidden zipper can be installed on the fabric through the adhesive layer without sewing. Furthermore, the edge of the zipper tape is bent inward in a U-shape, so that the sewing thread does not interfere with the arrangement of the adhesive layer and is difficult to be visually felt from the outside of the fabric. In addition, in the concealed zipper installation product including the concealed zipper semi-finished product, the slider passes through the edge of the fastener element and the zipper tape, but does not penetrate into the fabric, that is, the fabric does not pass through the slider. Therefore, the sliding of the slider on the fastener element is not affected by the thickness of the fabric, and the fabric is not susceptible to sliding marks or damage due to the slider sliding relative to the fastener element. In addition, in the finished installation of concealed zippers, the zip chain, adhesive layer and slider are hidden on the inner surface of the fabric. In this way, the concealed zipper semi-finished product of the concealed zipper applied to the fabric has a beautiful appearance.
