Description
本案係有關一種拉鏈，尤指一種具防滲功能之拉鏈。This case relates to a zipper, especially a zipper with anti-seepage function.
由於拉鏈被使用於不同的物品，故出現之場合亦有所不同，使用於戶外運動之衣著與器材常須具備防水功能，例如雪衣、風衣、雨衣、帳篷，乃至於滑雪或旅行裝備。Since zippers are used for different items, the occasions where they appear are also different. Clothing and equipment used in outdoor sports often have to be waterproof, such as snowsuits, windbreakers, raincoats, tents, and even skis or travel equipment.
事實上，拉鏈最容易滲水之處係在一對支撐布帶的一中央隙縫位置，也是最難克服之問題。如本案發明人所擁有之本國專利公告第I374714及I395555號專利案(對應於美國專利公告第US 8,397,353 B2、8,484,810 B2及8,689,408 B2專利案)，該等專利案雖已揭示一高分子彈性體充塞於一拉鏈的一對支撐布帶的一中央隙縫，以及一對扣合元件中該對連續式扣合元件之間相鄰的的隙縫，以克服橫向力所造成的滲水問題。In fact, the most susceptible part of the zipper to the water is a central slot of a pair of supporting tapes, which is also the most difficult problem to overcome. For example, national patent publications Nos. I374714 and I395555 (corresponding to U.S. Patent Publications Nos. 8,397,353 B2, 8,484,810 B2 and 8,689,408 B2) owned by the inventors of this case, although these patent cases have revealed a polymer elastomer stuffing A central slit in a pair of supporting cloth tapes of a zipper and an adjacent gap between the pair of continuous fastening elements in a pair of fastening elements to overcome the problem of water seepage caused by lateral forces.
惟前述高分子彈性體只是充塞在該對連續式扣合元件之間相鄰的垂直(縱向)隙縫，並未橫向深入該對連續式扣合元件之內腔，以致對該對連續式扣合元件之包覆並非完整，因此該高分子彈性體與該對連續式扣合元件的上層之間仍存有隙縫，使液體容易從該隙縫滲入，使用時也容易造成該高分子彈性體的鬆動與脫落，因而減弱了防滲水之功能。However, the aforementioned polymer elastomer only fills the adjacent vertical (longitudinal) gap between the pair of continuous fastening elements, and does not penetrate deeply into the inner cavity of the pair of continuous fastening elements, so that the pair of continuous fastening elements The covering of the element is not complete, so there is still a gap between the polymer elastomer and the upper layer of the pair of continuous fastening elements, so that liquid easily penetrates through the gap, and it is easy to cause the polymer elastomer to loosen during use. And fall off, thereby weakening the function of preventing water seepage.
如圖1所示，乃匝圈式連續拉鏈之防滲結構的縱向剖面圖，一防滲彈性膠體5充塞於一支撐布帶1的一中央隙縫內及彼此相鄰連續式扣合元件2的縱向(垂直)間隙22，但該防滲彈性膠體5並沒有貫穿及充塞於該對連續式扣合元件2各自的一內腔21內。因此，該防滲彈性膠體5未能整圈包覆該對連續式扣合元件2的一上層2a，以致液體容易從該對連續式扣合元件2的該上層2a和該內腔21處滲入。再者，由於該防滲彈性膠體5未能整圈包覆該連續式扣合元件2的該上層2a，以致沒有錨碇作用，進而降低該彈性膠體5與各該連續式扣合元件2的結合牢度，因此在使用時，該防滲彈性膠體5與各該連續式扣合元件2的結合容易鬆動，輕者液體容易從該內腔21滲水，無法達到預期的防滲功能外；嚴重者，該防滲彈性膠體5與該對連續式扣合元件2因鬆動而造成脫落，而亟待改善。As shown in FIG. 1, it is a longitudinal sectional view of the anti-seepage structure of the loop-type continuous zipper. An anti-seepage elastic gel 5 is stuffed in a central gap of a supporting tape 1 and adjacent continuous fastener elements 2. The longitudinal (vertical) gap 22, but the impervious elastomeric gel 5 does not penetrate and stuff into an inner cavity 21 of each of the pair of continuous fastening elements 2. Therefore, the impermeable elastic colloid 5 cannot cover an upper layer 2a of the pair of continuous fastening elements 2 in a full circle, so that the liquid easily penetrates from the upper layer 2a and the inner cavity 21 of the pair of continuous fastening elements 2. . Furthermore, because the impermeable elastic colloid 5 cannot cover the upper layer 2a of the continuous fastening element 2 in a full circle, so that there is no anchoring effect, thereby reducing the elastic colloid 5 and each of the continuous fastening elements 2 The binding fastness, therefore, when in use, the combination of the impermeable elastic colloid 5 and each of the continuous fastening elements 2 is easy to loosen, and the lighter liquid easily leaks water from the inner cavity 21, and cannot achieve the desired anti-seepage function; serious In other words, the impermeable elastic colloid 5 and the pair of continuous fastening elements 2 fall off due to looseness, and need to be improved urgently.

The pair of continuous fastening elements 2 are stitched or knitted, the former is called Sewing zippers, the latter of which are called braided zippers, for example, the pair of continuous fastening elements 2 are each bonded to the inner sides of the second faces 1b of the pair of supporting tapes 1 by at least one fixing thread 3 or by weaving warp and weft edge. An inner cavity 21 is formed inside each of the continuous fastening elements 2, and an upper layer 2 a and a lower layer 2 b are oppositely provided on the outside. When necessary, a core wire 4 may be provided in the inner cavity 21 of each of the continuous fastening elements 2 to increase the strength and stability of the zipper.
該第一實施例實施時，該拉鏈在扣合狀態下，經由一灌膠工序將由一彈性高分子材料，例如但不限於熱可塑聚氨基甲酸酯彈性體(thermoplastic polyurethane elastomer)、聚氨基甲酸酯彈性體(polyurethane elastomer)或熱可塑聚酯彈性體(thermoplastic polyester elastomer)製成的一防滲彈性膠體5從該中央隙縫11注入，使該防滲彈性膠體5充塞於該中央隙縫11內和該對連續式扣合元件2中彼此相鄰之縱向(垂直)間隙22內，並進一步橫向滲入該對連續式扣合元件2的各該內腔21內，使該對連續式扣合元件2的該上層2a至少一部分被該防滲彈性膠體5整圈包覆，以防止液體經由該對連續式扣合元件2的該上層2a的表面滲入。最後在該中央隙縫11位置縱向分割該防滲彈性膠體5，以形成一切口51，使該拉鏈具有開合功能。When the first embodiment is implemented, the zipper is in a fastened state and is made of an elastic polymer material, such as, but not limited to, a thermoplastic polyurethane elastomer, polyurethane, through a potting process. An impervious elastomeric gel 5 made of a polyurethane elastomer or a thermoplastic polyester elastomer is injected from the central gap 11, so that the impervious elastomeric gel 5 fills the central gap 11. And the longitudinal (vertical) gap 22 adjacent to each other in the pair of continuous fastening elements 2 and further penetrated laterally into each of the inner cavities 21 of the pair of continuous fastening elements 2 so that the pair of continuous fastening elements 2 At least a part of the upper layer 2a of 2 is covered by the full circle of the impervious elastic gel 5 to prevent liquid from penetrating through the surfaces of the upper layer 2a of the pair of continuous fastening elements 2. Finally, the anti-seepage elastic colloid 5 is divided longitudinally at the position of the central slit 11 to form all openings 51, so that the zipper has an opening and closing function.
圖3所示為圖2所示拉鏈之另一方向(縱向)剖面圖，前已述及，該防滲彈性膠體5除了充塞於該中央隙縫11內和該對連續式扣合元件2中彼此相鄰之縱向間隙22內之外，更進一步貫穿該對連續式扣合元件2的各該內腔21內，因此該防滲彈性膠體5可以整圈包覆該對連續式扣合元件2的該上層2a的至少一部份。此舉所獲益的功效如下列所示：FIG. 3 is a sectional view in another direction (longitudinal direction) of the zipper shown in FIG. 2. As mentioned above, the impervious elastic gel 5 is filled with each other in the central slit 11 and the pair of continuous fastening elements 2. Inside and outside the adjacent longitudinal gaps 22 further penetrate each of the inner cavities 21 of the pair of continuous fastening elements 2, so the impervious elastic gel 5 can cover the pair of continuous fastening elements 2 in a full circle. At least a part of the upper layer 2a. The benefits of this move are as follows:
(1)、提高該拉鏈之防滲功能，使該中央隙縫11因該防滲彈性膠體5的設置可抵抗至少50mm高之水壓；(1) Improving the anti-seepage function of the zipper, so that the central slit 11 can resist the water pressure of at least 50mm due to the setting of the anti-seepage elastic colloid 5;
(2)、該防滲彈性膠體5在該對連續式扣合元件2的各該內腔21內形成連接，以防止該防滲彈性膠體5由該對連續式扣合元件2上脫落；以及(2) the impermeable elastic colloid 5 forms a connection in each of the inner cavities 21 of the pair of continuous fastening elements 2 to prevent the impermeable elastic colloid 5 from falling off from the pair of continuous fastening elements 2; and
(3)、因為該防滲彈性膠體5包覆該對扣合元件2的該上層2a，並產生錨碇作用，從而增加該防滲彈性膠體5與該對連續式扣合元件2的結合力，所以能大幅延長該拉鏈防滲功能的使用時間。(3) Because the impermeable elastic colloid 5 covers the upper layer 2a of the pair of fastening elements 2 and generates an anchoring effect, thereby increasing the binding force of the impermeable elastic colloid 5 and the pair of continuous fastening elements 2 Therefore, the use time of the anti-seepage function of the zipper can be greatly prolonged.
如圖4所示，其揭示本案拉鏈的第二實施例，該第二實施例相較於第一實施例相同的標號(符號)用以表示相同的構件，由於該第二實施例與該第一實施例分享許多共用的構件，因而僅將兩者的差異處詳予說明於後。As shown in FIG. 4, it discloses a second embodiment of the zipper of the present case. The second embodiment is compared with the first embodiment with the same reference numerals (symbols) to indicate the same components. An embodiment shares many common components, so only the differences between the two will be explained in detail later.
該對連續式扣合元件2係採用折疊式連續扣合元件(lapped fastening elements)，該對連續式扣合元件2以車縫方式，例如以至少一固定線3將該對連續式扣合元件2各自結合於該對支撐布帶1的該等第二面1b的內側緣。必要時可設置該芯線4在各該連續式扣合元件2的該內腔21內，以增加該拉鏈之強度與穩定度。The pair of continuous fastening elements 2 is a folded continuous fastening element. The pair of continuous fastening elements 2 is stitched, for example, the pair of continuous fastening elements is at least one fixing wire 3. 2 are each bonded to the inner edges of the second faces 1b of the pair of supporting tapes 1. If necessary, the core wire 4 may be provided in the inner cavity 21 of each of the continuous fastening elements 2 to increase the strength and stability of the zipper.
該第二實施例實施時，該拉鏈在扣合狀態下，經由前述灌膠工序將該防滲彈性膠體5從該中央隙縫11注入，使該防滲彈性膠體5充塞於該中央隙縫11內和該對連續式扣合元件2中彼此相鄰之縱向間隙22內，並進一步橫向滲入該對連續式扣合元件2的各該內腔21內，使該對連續式扣合元件2的該上層2a至少一部分被該防滲彈性膠體5整圈包覆，以防止液體經由該對連續式扣合元件2的該上層2a表面滲入。最後在該中央隙縫11位置縱向分割該防滲彈性膠體5，以形成該切口51，使該拉鏈具有開合功能。When the second embodiment is implemented, the zipper is in the fastened state, and the impermeable elastic gel 5 is injected from the central slit 11 through the aforementioned filling process, so that the impermeable elastic gel 5 is stuffed in the central slit 11 and The longitudinal gaps 22 adjacent to each other in the pair of continuous fastening elements 2 penetrate further into each of the inner cavities 21 of the pair of continuous fastening elements 2 so that the upper layer of the pair of continuous fastening elements 2 At least a part of 2a is covered by the full circle of the impervious elastic gel 5 to prevent liquid from penetrating through the surface of the upper layer 2a of the pair of continuous fastening elements 2. Finally, the impervious elastic gel 5 is divided longitudinally at the position of the central slot 11 to form the cutout 51, so that the zipper has an opening and closing function.
如圖5所示，其揭示本案拉鏈的第三實施例，該第三實施例相較於第一實施例相同的標號(符號)用以表示相同的構件，由於該第三實施例與該第一實施例分享許多共用的構件，因而僅將兩者的差異處詳予說明於後。As shown in FIG. 5, it discloses a third embodiment of the zipper of the present case. The third embodiment is compared with the first embodiment by using the same reference numerals (symbols) to indicate the same components. An embodiment shares many common components, so only the differences between the two will be explained in detail later.
該第三實施例為一種隱形拉鏈，因此該對連續式扣合元件2，例如與該第一實施例採用相同的匝圈式連續扣合元件係相對設置在該對支撐布帶1之該等第一面1a呈反折狀的內側緣，該對連續式扣合元件2的該至少一固定線3及其車縫針孔係隱藏在該對支撐布帶1之該等第二面1b的內側緣，因此可防止該對支撐布帶1的車縫針孔滲水問題。其中，該對連續式扣合元件2不以前述匝圈式連續扣合元件為限，其亦得採用該第二實施例所示折疊式連續扣合元件。The third embodiment is an invisible zipper. Therefore, the pair of continuous fastening elements 2 is, for example, the same loop-type continuous fastening elements as the first embodiment, which are oppositely disposed on the pair of supporting tapes 1 and the like. The first surface 1a has a reverse-shaped inner edge. The at least one fixing line 3 of the pair of continuous fastening elements 2 and the stitching pinholes thereof are hidden in the second surfaces 1b of the pair of supporting tapes 1. The inner edge, therefore, prevents the problem of water seepage from the stitched pinholes of the pair of support tapes 1. Wherein, the pair of continuous fastening elements 2 is not limited to the aforementioned turn-type continuous fastening elements, and they may also adopt the folding continuous fastening elements shown in the second embodiment.
該第三實施例實施時，該拉鏈在扣合狀態下，經由前述灌膠工序將由彈性高分子材料製成的該防滲彈性膠體5從該中央隙縫11注入，使該防滲彈性膠體5充塞於該中央隙縫11內和該對連續式扣合元件2中彼此相鄰之縱向間隙22內，並進一步橫向滲入該對連續式扣合元件2的各該內腔21內，使該對連續式扣合元件2的該上層2a至少一部分被該防滲彈性膠體5整圈包覆，以防止液體經由該對連續式扣合元件2的該上層2a表面滲入。最後在該中央隙縫11位置縱向分割該防滲彈性膠體5，以形成該切口51，使該拉鏈具有開合功能。In the implementation of the third embodiment, the zipper is in the fastened state, and the impervious elastic colloid 5 made of an elastic polymer material is injected from the central gap 11 through the aforementioned filling process, so that the impervious elastic colloid 5 is stuffed. In the central slot 11 and in the longitudinal gaps 22 adjacent to each other in the pair of continuous fastening elements 2, and further penetrate laterally into the inner cavities 21 of the pair of continuous fastening elements 2, so that the pair of continuous At least a part of the upper layer 2a of the fastening element 2 is covered with a full circle by the impermeable elastic gel 5 to prevent liquid from penetrating through the surfaces of the upper layer 2a of the pair of continuous fastening elements 2. Finally, the impervious elastic gel 5 is divided longitudinally at the position of the central slot 11 to form the cutout 51, so that the zipper has an opening and closing function.
請再參閱圖2至圖5，前已述及，該防滲彈性膠體5係一體成型於該中央隙縫11內、該對連續式扣合元件2中彼此相鄰之縱向間隙22內和該對連續式扣合元件2的各該內腔21內，使得該防滲彈性膠體5完全包覆該對連續式扣合元件2的該上層2a，並產生錨碇功能，以防止該防滲彈性膠體5在使用時從該拉鏈上脫落。Please refer to FIGS. 2 to 5 again. As mentioned earlier, the impermeable elastic colloid 5 is integrally formed in the central slot 11, the longitudinal gap 22 adjacent to each other in the pair of continuous fastening elements 2, and the pair. Each of the inner cavities 21 of the continuous fastening element 2 allows the impermeable elastic colloid 5 to completely cover the upper layer 2a of the pair of continuous fastening elements 2 and generates an anchor function to prevent the impermeable elastic colloid 5Drop off from the zipper during use.
另為避免該防滲彈性膠體5與一拉鏈頭產生磨擦，所以該防滲彈性膠體5必須被該對支撐布帶1約束在該中央隙縫11內，且該防滲彈性膠體5的高度低於該對支撐布帶1的該等第一面1a。In addition, in order to avoid friction between the impervious elastic colloid 5 and a zipper head, the impervious elastic colloid 5 must be restrained by the pair of supporting tapes 1 in the central gap 11, and the height of the impervious elastic colloid 5 is lower than The first surfaces 1 a of the pair of supporting tapes 1.
此外，在該第一至該第三實施例中，該對支撐布帶1最內側邊緣的至少一條經紗比其他的經紗粗，以產生類似河堤之功能，以防止該防滲彈性膠體5溢出該中央隙縫11，並沾黏到該對支撐布帶1的該等第一面1a，因而影響該拉鏈外觀。所以在實施上，該對支撐布帶1最內側邊緣的該至少一條經紗必須較粗，若習知支撐布帶係由150de(丹尼)或300de的紗線織造而成，則本案的該對支撐布帶1最內側邊緣的該至少一條經紗粗細以450de或以上為佳。再者，可將該對支撐布帶1之鎖鏈(chain-stitch)組織邊作為內側邊緣，或將該對支撐布帶內側改為相對較厚的組織，都有助於增加該防滲彈性膠體5在該中央隙縫11內之厚度，並使在該中央隙縫11內的該防滲彈性膠體5邊緣更為筆直，既可增加防滲功能又可增加美觀。In addition, in the first to the third embodiments, at least one warp yarn of the innermost edge of the pair of supporting tapes 1 is thicker than other warp yarns, so as to produce a function similar to a river bank to prevent the impermeable elastic colloid 5 from overflowing. The central slit 11 is adhered to the first surfaces 1 a of the pair of supporting tapes 1, thereby affecting the appearance of the zipper. Therefore, in practice, the at least one warp yarn of the innermost edge of the pair of supporting tapes 1 must be relatively thick. If it is known that the supporting tapes are woven from 150de (denier) or 300de yarns, the pair in this case The thickness of the at least one warp yarn of the innermost edge of the supporting tape 1 is preferably 450 de or more. Furthermore, the chain-stitch tissue edge of the pair of support tapes 1 can be used as the inner edge, or the inside of the pair of support tapes can be changed to a relatively thick tissue, both of which can help increase the impermeable elastic colloid. The thickness of 5 in the central slit 11 and the edges of the anti-seepage elastic colloid 5 in the central slit 11 are more straight, which can increase the anti-seepage function and increase the appearance.
再者，該對連續式扣合元件2各自係以雙道固定線3各自結合於該對支撐布帶1的內側緣，並在該對連續式扣合元件的該等下層2b形成鎖鏈狀之雙道鎖鏈。若各該連續式扣合元件2的該下層2b設有一凹槽(未予以圖示)，即能容納該固定線3，以減少該固定線3與該拉鏈頭之間的磨擦，進而增加該拉鏈之耐用度。Furthermore, the pair of continuous fastening elements 2 are each connected to the inner edge of the pair of supporting tapes 1 with two fixing wires 3, and form a chain-like shape on the lower layers 2b of the pair of continuous fastening elements. Double chain. If the lower layer 2b of each of the continuous fastening elements 2 is provided with a groove (not shown), the fixing wire 3 can be accommodated to reduce friction between the fixing wire 3 and the zipper head, thereby increasing the Durability of the zipper.
另者，該芯線4可為含有具極性的尼龍纖維之紗線，以增加該防滲彈性膠體5與該芯線4之黏著力。同樣地，該對支撐布帶1的適當位置，例如該對支撐布帶1的最內側邊緣或該對支撐布帶1的反折狀表面配置具極性的尼龍纖維，可提升該防滲彈性膠體5與該對支撐布帶1之結合牢度，進而提升防滲功能及耐用度。In addition, the core wire 4 may be a yarn containing polar nylon fibers to increase the adhesion between the impermeable elastic gel 5 and the core wire 4. Similarly, the appropriate position of the pair of support tapes 1, such as the innermost edge of the pair of support tapes 1 or the reverse-folded surfaces of the pair of support tapes 1, is configured with polar nylon fibers, which can enhance the impermeable elastic gel. The fastness of the combination of 5 and the pair of supporting cloth tapes 1 further improves the anti-seepage function and durability.
尤有進者，該第一至該第三實施例所示拉鏈可經由防潑水加工，使該對支撐布帶1具防潑水功能；或該對支撐布帶1係以具撥水功能的纖維紗織造而成，以省去防潑水加工所產生的廢水；或者該對支撐布帶1係採用以低於1丹尼纖維搭配熱縮收纖維織造成之超密織帶，並經防潑水加工，以提升拉鏈整體之防滲功能。In particular, the zippers shown in the first to the third embodiments can be subjected to water-repellent processing, so that the pair of supporting cloth tapes 1 has a water-repellent function; or the pair of supporting cloth tapes 1 are made of fibers with a water-repellent function. Yarn is woven to eliminate waste water from water repellent processing; or the pair of support tapes 1 are made of ultra-dense webbing made of less than 1 denier fiber with heat-shrinkable fiber, and subjected to water repellent processing. To improve the overall impermeability of the zipper.
如圖6所示，其揭示本案拉鏈的第四實施例，該第四實施例相較於第一實施例相同的標號(符號)用以表示相同的構件，由於該第四實施例與該第一實施例分享許多共用的構件，因而僅將兩者的差異處詳予說明於後。As shown in FIG. 6, it discloses a fourth embodiment of the zipper of the present case. The fourth embodiment is compared with the first embodiment with the same reference numerals (symbols) to indicate the same components. Since the fourth embodiment and the first embodiment An embodiment shares many common components, so only the differences between the two will be explained in detail later.
該對連續式扣合元件2係採用夾式連續式扣合元件，接著將該對連續式扣合元件2各自夾設於該對連續式扣合元件2的內側緣，且該對連續式扣合元件2各自具有一內腔21；接著，對各該連續式扣合元件2的一上層2a及一下層2b各自覆蓋一第一織帶6a及一第二織帶6b，然後將該對連續式扣合元件2以車縫方式，例如以至少一固定線3將該對連續式扣合元件2的該等上層2a及該等下層2b各自結合於該對支撐布帶1與該對第一織帶6a之間的內側緣及該對支撐布帶1與該對第二織帶6b之間的內側緣，使該對支撐布帶1、該對第一織帶6a及該對第二織帶6b之間共同形成一中央隙縫11。The pair of continuous fastening elements 2 are clip-type continuous fastening elements, and then the pair of continuous fastening elements 2 are each clamped on the inner edge of the pair of continuous fastening elements 2 and the pair of continuous fastening elements Each of the fastening elements 2 has an inner cavity 21; then, an upper layer 2a and a lower layer 2b of each of the continuous fastening elements 2 respectively cover a first webbing 6a and a second webbing 6b, and then the pair of continuous fastening The upper element 2a and the lower layer 2b of the pair of continuous fastening elements 2 are each stitched to the pair of supporting tapes 1 and the first webbing 6a in a sewing manner, for example, with at least one fixing line 3. The inner edge between the pair and the inner edge between the pair of support tapes 1 and the second webbing 6b, so that the pair of support tapes 1, the first webbing 6a and the second webbing 6b are formed together一 centric gap 11.
該第四實施例實施時，該拉鏈在扣合狀態下，經由前述灌膠工序將由彈性高分子材料製成的一防滲彈性膠體5從該中央隙縫11頂部或底部注入，使該防滲彈性膠體5充塞於該中央隙縫11內和該對連續式扣合元件2中彼此相鄰之縱向間隙22內，並進一步橫向滲入該對連續式扣合元件2的各該內腔21內，使該對連續式扣合元件2的該等上層2a及該等下層2b被該防滲彈性膠體5所包覆，以防止液體經由該對連續式扣合元件2的該等上層2a及該等下層2b表面滲入，並可防止該防滲彈性膠體5從拉鏈上脫落。最後在該中央隙縫11位置縱向分別分割該防滲彈性膠體5，以形成該切口51，使該拉鏈具有開合功能。In the implementation of the fourth embodiment, in the buckled state, an anti-permeability elastic colloid 5 made of an elastic polymer material is injected from the top or bottom of the central slit 11 through the aforementioned filling process to make the impermeability elastic The colloid 5 fills the central gap 11 and the longitudinal gaps 22 adjacent to each other in the pair of continuous fastening elements 2 and further penetrates laterally into the inner cavities 21 of the pair of continuous fastening elements 2 so that the The upper layers 2a and the lower layers 2b of the continuous fastening element 2 are covered by the impermeable elastic colloid 5 to prevent liquid from passing through the upper layers 2a and the lower layers 2b of the continuous fastening element 2 The surface penetrates and prevents the impermeable elastic gel 5 from falling off the zipper. Finally, the anti-seepage elastic colloid 5 is divided longitudinally at the position of the central slit 11 to form the cutout 51, so that the zipper has an opening and closing function.
該第四實施例係採用該對夾式連續式扣合元件2，其分別設置於各該支撐布帶1的該第一面1a的內側緣及該第二面1b的內側緣，並利用各該連續式扣合元件2的方型結構與車縫固定方式，其可阻擋各該連續式扣合元件2的該至少一固定線3往外側滑動的問題。因此，該第四實施例可改善該中央隙縫11被橫向外力所引起的擴之問題，進而提升該拉鏈之防滲功能。The fourth embodiment adopts the pair of clip-type continuous fastening elements 2, which are respectively disposed on the inner edge of the first surface 1a and the inner edge of the second surface 1b of each of the supporting tapes 1, and use each The square structure and the seam fixing method of the continuous fastening element 2 can block the problem that the at least one fixing line 3 of each continuous fastening element 2 slides to the outside. Therefore, the fourth embodiment can improve the problem that the central slit 11 is expanded by a lateral external force, thereby improving the anti-seepage function of the zipper.
此外，該第一織帶6a及該第二織帶6b最內側邊緣的該至少一條經紗比其他的經紗粗，或最內側邊緣的編織組織相對較厚，可以防止該防滲彈性膠體5溢到該第一織帶6a和該第二織帶6b之表面。In addition, the at least one warp yarn at the innermost edge of the first webbing 6a and the second webbing 6b is thicker than other warp yarns, or the weaving structure of the innermost edge is relatively thick, which can prevent the impermeable elastic colloid 5 from overflowing to the first The surface of a webbing 6a and the second webbing 6b.
再者，該對支撐布帶1、該對第一織帶6a及該對第二織帶6b的內側緣，例如至少一條經紗為尼龍材質，利用尼龍材質的極性，可以提高該防滲高彈性膠體5與該對支撐布帶1、該對第一織帶6a及該對第二織帶6b的黏著力。In addition, the inner edges of the pair of supporting fabric tapes 1, the first webbing 6a, and the second webbing 6b, for example, at least one warp yarn is made of nylon. By using the polarity of the nylon material, the impermeable and highly elastic gel 5 Adhesion to the pair of supporting fabric tapes 1, the first webbing 6a and the second webbing 6b.
於實務上，該對支撐布帶1、該對連續式扣合元件2與該防滲彈性膠體5的黏著力影響該拉鏈的防滲功能最為巨大，因此該防滲彈性膠體5的材質若為聚氨酯彈性膠體時，則與該防滲彈性膠體5接觸的該對支撐布帶1、該芯線4及該對連續式扣合元件2等可選擇具極性的尼龍(polyamide)材質，該極性的尼龍與該防滲彈性膠體5間之黏著力比聚酯為佳，因此可以提升該防滲彈性膠體5與該拉鏈的黏著力，以避免該防滲彈性膠體5與該拉鏈間因黏著力不良而產生脫落，甚至喪失防滲功能的問題。若該連續式扣合元件2同為尼龍材質時，可先用離型劑處理後，再注入該防滲彈性膠體5以利於分割。In practice, the adhesion of the pair of support tapes 1, the pair of continuous fastening elements 2 and the impervious elastic colloid 5 has the greatest effect on the impermeability of the zipper. Therefore, if the material of the impervious elastic colloid 5 is In the case of polyurethane elastic colloid, the pair of supporting tapes 1, the core wire 4 and the pair of continuous fastening elements 2 which are in contact with the impervious elastic colloid 5 can be selected from polar nylon materials. The polar nylon The adhesion between the impervious elastic colloid 5 and polyester is better than that of polyester, so the adhesion between the impervious elastic colloid 5 and the zipper can be improved to avoid poor adhesion between the impervious elastic colloid 5 and the zipper. Problems such as shedding and even loss of anti-seepage function occur. If the continuous fastening element 2 is also made of nylon, it can be treated with a release agent before being injected with the impermeable elastic colloid 5 to facilitate division.
如圖7所示，其顯示該第一實施例的另一變形實施例，事實上，經防潑水加工的該對支撐布帶1基本上並無抗水壓功能，若該對支撐布帶1也要達到抗水壓功能，則該對支撐布帶1的該等第一面1a或該等第二面1b中的至少一面必須覆蓋，例如塗佈或貼合一防水層9。該防水層9覆蓋於該對支撐布帶1的該等第一面1a及/或該等第二面1b和位於該中央隙縫11位置的該防滲彈性膠體5，並在該中央隙縫11位置縱向分割該防滲彈性膠體5及該防水層9，以形成該切口51，使該拉鏈具有開合功能，透過前述的實施，使該拉鏈包括該對支撐布帶1都可達水柱高度50mm以上的防滲功能。As shown in FIG. 7, it shows another modified embodiment of the first embodiment. In fact, the pair of supporting tapes 1 subjected to water repellent processing basically does not have a function of resisting water pressure. To achieve the function of resisting water pressure, at least one of the first surface 1a or the second surface 1b of the pair of supporting tapes 1 must be covered, for example, a waterproof layer 9 is coated or adhered. The waterproof layer 9 covers the first faces 1a and / or the second faces 1b of the pair of supporting tapes 1 and the impermeable elastic gel 5 at the position of the central slit 11, and is located at the position of the central slit 11. The impermeable elastic colloid 5 and the waterproof layer 9 are longitudinally divided to form the cutout 51, so that the zipper has an opening and closing function.

基本上，該防水層9可以是一熔點150°C以上之高溫熱熔膠塗佈層，例如尼龍或經電漿處裡的聚酯等材質的該對支撐布帶1的該等第一面1a塗佈聚氨基甲酸酯(PU)彈性體，因兩者皆為極性物質，所以能穩固地黏著；或者該防水層9包括一防水膜91及一接著層92，其總厚度一般在0.2mm以下，該接著層92貼合後會有一部分滲入該對支撐布帶1的組織內，以產生錨碇作用，另一部分則作為與該防水膜91之結合層。其中，該防水膜91必須是不滲水材質，例如選自聚醚型聚氨酯薄膜(ether base PU film)、聚酯型聚氨酯薄膜(ester base PU film)、尼龍薄膜(nylon film)或聚酯薄膜(PET film)等，該防水膜91的厚度約在0.1mm以下為佳。而該接著層92則選自濕氣固化聚氨酯熱熔膠、水性聚氨酯熱熔膠、封閉型聚氨酯熱熔膠或聚氨酯膠等。Basically, the waterproof layer 9 can be a high-temperature hot-melt adhesive coating layer with a melting point of 150 ° C or higher, such as the first pair of the supporting tapes 1 made of nylon or polyester in the plasma. Polyurethane (PU) elastomer is coated on the surface 1a, because both are polar materials, so they can be firmly adhered; or the waterproof layer 9 includes a waterproof film 91 and an adhesive layer 92, and the total thickness is generally between Below 0.2 mm, a part of the adhesive layer 92 will penetrate into the tissues of the pair of supporting tapes 1 after bonding to produce an anchor effect, and the other part will serve as a bonding layer with the waterproof film 91. The waterproof film 91 must be a water-impermeable material, for example, selected from a polyether-based polyurethane film (ether base PU film), a polyester-based polyurethane film (ester base PU film), a nylon film or a polyester film ( PET film) and the like, and the thickness of the waterproof film 91 is preferably about 0.1 mm or less. The adhesive layer 92 is selected from moisture-curable polyurethane hot-melt adhesive, water-based polyurethane hot-melt adhesive, closed-type polyurethane hot-melt adhesive, or polyurethane adhesive.
