The technique of using a solvent type pu followed by a film attached to a cloth. In the United States, the fourth, 724, 5 $ ^ ^ 6, 105, 214 ' and 6, 427, 294 and other patents also reveal how to separate the waterproof pull, the waterproof film between the two cloth strips, and the waterproof film is divided into left and right sides of the waterproof zipper The lack of the necessary conditions, and the difference between the domestic patent No. 1220106 is only the selected hot-melt adhesive or solvent-based adhesive, which is easy for the skilled person to know, and not progressive. Patent requirements. In fact, the aforementioned patents No. 1220106, No. 6,105,214, and No. 6,427,294 of the United States, in order to paste the film, are pressed against the unevenness of the cloth texture, so that the The waterproof film is stretched. Therefore, the water-repellent film in the center-slot seam shrinks to the sides after being divided, so that the edge of the tape is outside the water film, so that the tape leaks due to the capillary phenomenon. The depth of the movement is shown in Figure 1. It is a picture of the US Patent No. 4,580,321]. The continuous loop-type waterproof zipper is used to make the center gap close together, so that the elastomeric sealing member 15 The edge of the fastener element 12 is almost aligned with the inner side of the fastening member 12, and the position of the core wire 13 is at the outermost side of the inner cavity of the fastening member 12. In addition, the tension of the suture 14 is adjusted, and the purpose is to prevent the waterproof zipper from being subjected to lateral external force. The seam of the tape 11 is enlarged, and the waterproof function is lost. Μ 6 201004583 Φ

The raised portion (rajsedp〇|^〇ns) i7, the missing is: (1) the waterproof film 15 directly rubs the gap in the zipper head and (2) when the waterproof zipper is separated left and right, 'pull_ and zipper, , , = a will basically be inclined "the waterproof film 15 is located just below the needle ^ in the zipper head, and is directly scratched. Since the fastening element 12 is engaged at a non-horizontal angle, in addition to increasing the frictional resistance inside the zipper head, it is often caused by excessive shrinkage caused by dyeing, and the central slit is turned into a left-right overlapping shape. The film 15 is worn by the zipper head, and in severe cases, the waterproof zipper is made into a waste product. In addition, due to the tight tension of the sewing seam, the anti-chain is too hard to measure the long button, which is also a problem with the waterproof zipper. The central slot of the square water zipper is tight and not easy to open. As shown in Figure No. (10), No. 294 of the Patent No. 8, No. 294, after the central f is sewed, the low-melting resin is laminated on the surface of the tape 3, followed by the layer 12, 're-bonding one or two refining resin. The layer 13, that is, the water-repellent thinness t, / the remaining water-repellent fine 13 is not enough for the vertical surface of the rib's entire cloth edge, let alone extending to the bottom of the slit. Therefore, the component 8 of the case is a laminate of a synthetic resin film (m) which is integrally formed of the low-melting resin layer 12 and is not a water-repellent film 13. As for the case, Figure 13 and Figure 14 are double-layered fasteners. It is not the object of implementation in this case, so the scope of the discussion is not discussed. Ϊί =!^ When using f, often because the clothes are too tight or the bag is too full, the taste is strong, forcing the left and right cloths to slip on both sides and the gap appears. This 7 (4) 6,427,294 No. # design material, for example As shown in Fig. 10, the excess width of the waterproof film 13 will not be sufficient to cover the 201004583 (four) seam, and still ride the bristles of the belt, and then lose the same as shown in Fig. 4, which is the fourth section of the United States.

The first processing step is (8) The zipper is in the natural fastening state, and the central slit 5 of the left and right cloth belts 1 is not closely connected ^ State, for example, the slit width is at least 〇3 mm. Therefore, the two fabrics, by means of an external force, for example, using a wedge-shaped bar to force the central slit 5 to be in an expanded state, in order to perform any of the aforementioned waterproof film bonding steps, when the external force is removed, the width of the central slit 5 of the zipper will gradually recover. That is, the central slit 5 will be reduced to a width close to the original, and due to factors such as gravity and space, the waterproof film 3 must be recessed horizontally downward to accommodate its excess waterproof film. (=) and the portion of the waterproof film that is recessed downward, after being divided by the conventional cutting step, the excess free end 31 at the surface of the bribe _ 3 f can resist the force of the zipper to the left and right sides of the zipper 1 become smaller.

The second processing step is as follows: (a) The zipper having at least 〇3 mm slit at the time of fastening is applied to the first surface 13 of the separated state 201004583 1 by applying an adhesive 4, such as a solvent glue, and respectively conforming to a predetermined width. The waterproof film 3 is such that the inner edge of the anti-film 3 covers the vertical side μ of the tape j and is directed to the center line corresponding to the center slit 5 after the fastening. = The fastening member of the left and right cloth tapes of the above-mentioned waterproof film 3 has been attached, and the excess free end 31 of the film 3 is at the center of force to achieve a waterproof effect.雠 雠 (10) ❹ 1 4 ^ Figure 7 lion 'County * waterproof pull miscellaneous know the waterproof zipper cloth in the head relative position diagram, the waterproof zipper tape of this case i f, so that the waterproof film 3 due to the concave shape, and avoid The upper ribs 61 and _ 62 in the zipper head 6 can prevent the waterproof film 15 from being worn: d is strictly lacking i1 and the waterproof zipper tape and its waterproof film are attached to the internal components of the zipper head 6, for example The upper rib 61 and the needle lock 62 are worn to form a defective product. "Ding frequency, 8" is a cross-sectional view of the embodiment of the waterproof zipper of the case, and the reference film 3 generates a stress in the central slit 5 which is mutually squeezed by the left and right sides. 俾 Formation: a surface point 32, thereby improving the waterproof effect. 2 shows a cross-sectional view of the waterproof zipper of the present embodiment, the excess free end 31 of the waterproof film 3 is in the central slit 5, and has a curved surface rim of the fastening member 2, so 'By the implementation of this case, the effect of its gain, Yu Hua, has the following number: The central slit of the soil 55 zipper* and the vertical side of the tape will be all covered with waterproof f, jin, and even redundant Free end in the gap, can completely remove the water seepage problem caused by capillary action. All 12 201004583 (^) The stitching of the fastening component and the tape does not need to be particularly dense, which is easy to produce, and the zipper is relatively soft; It is difficult to lead to the inside of the zipper head, which affects the sorting of the fastening components, thus reducing the failure and increasing the yield. (3) The waterproof film will touch each other at the bottom of the center slot, and the remaining free ends Serving The zipper is used in the gap that is opened by the external force to turn the function in the position. ❿ (4) The waterproof film covers the residual glue of the solvent-based adhesive in the gap, in addition to increasing the appearance. (4) Providing adhesion and water repellency. (5) Since the waterproof film of the tape is recessed and extends to the center of the center slit, it can avoid the upper ribs and the needle locks inside the zipper head, and the waterproof film is The lack of wear. 九四· ΛΛ (6 Ϊ zipper has a central slit design, do not worry about the dyeing caused by the over-contraction, the image, and thus the left and right overlap of the tape. The plastic is thin, and the vulcan is attached to the curved surface profile of the 7L piece to increase the tightness. (8) The width of the tape has a central slit, which is wide enough to avoid cutting the tape when cutting the waterproof film. No, it is one of the preferred embodiments. The technical thinking of the partial change of the secret case is easy for the person who is familiar with Wei Yi to be inferred, and the patent right of the case is not removed.
