Description
本發明係關於一種拉鍊,尤其是一種可防止液體滲透的阻水拉鍊。 The invention relates to a zipper, in particular to a water blocking zipper capable of preventing liquid penetration.
請參照第1、2圖,其係一種習知的防滲水拉鍊8,該習知的防滲水拉鍊8具有二布帶81,該二布帶81的相鄰邊分別具有一蕊部811,各該蕊部811分別結合有一列扣合元件82,該二列扣合元件82頂、底面的至少一面具有一凹槽821。該習知的防滲水拉鍊8另具有一防滲膠體83係在該二列扣合元件82處於扣合狀態下,被押注覆蓋該二列扣合元件82及該凹槽821內,以形成一覆蓋面層831,且該防滲膠體83同時滲入該二列扣合元件82與該對布帶81間之內部間隙,及滲入該二列扣合元件82另一面的間隙;藉由對該二列扣合元件82中間部位分割該覆蓋面層831,使該防滲水拉鍊8得以互為扣合或分離。類似於該習知的防滲水拉鍊8的一實施例已揭露於中華民國公告第I505788號「具有防滲結構之夾式扣合元件拉鍊」專利案當中。 Please refer to FIG. 1 and FIG. 2, which are a conventional water-proof zipper 8. The conventional water-proof zipper 8 has two cloth tapes 81, and adjacent edges of the two cloth tapes 81 each have a core portion 811. Each of the core portions 811 is respectively combined with a row of fastening elements 82, and at least one of the top and bottom surfaces of the two rows of fastening elements 82 has a groove 821. The conventional water-tight zipper 8 further has a water-proof gel 83 attached to the two rows of fastening elements 82 in a fastened state, and is betted to cover the two rows of fastening elements 82 and the grooves 821 to A covering surface layer 831 is formed, and the impermeable gel 83 penetrates into the internal gap between the two rows of fastening elements 82 and the pair of tapes 81 and the gap penetrated into the other side of the two rows of fastening elements 82; The covering surface layer 831 is divided at the middle portion of the two rows of fastening elements 82 so that the water-proof zipper 8 can be fastened or separated from each other. An embodiment similar to the conventional water-tight zipper 8 has been disclosed in the Republic of China Publication No. I505788 “Clip-type fastener element zipper with a water-tight structure” patent case.
上述習知防滲水拉鍊8藉由該覆蓋面層831覆蓋該二列扣合元件82,可以防止液體由該二列扣合元件82之間隙滲入,以達到防滲水的功效。然而,由於該二列扣合元件82相扣合的部位(第1圖中粗線W處)係形成緊密貼合而無間隙,造成該二列扣合元件82會有難以相互扣合或分離的情況。 The conventional water-proof zipper 8 covers the two rows of fastening elements 82 by the covering surface layer 831, which can prevent liquid from penetrating through the gap between the two rows of fastening elements 82 to achieve the effect of preventing water penetration. However, since the positions where the two rows of fastening elements 82 are engaged (the thick line W in the first figure) are formed tightly without gaps, it is difficult for the two rows of fastening elements 82 to be fastened or separated from each other. Case.
另一方面,該二列扣合元件82相互扣合時,其中一前述布帶81上的扣合元件82的最外端(齒頭)與另一前述布帶81的蕊部811之間留有明顯的間距H,使該防滲膠體83可以在該處形成一延伸部832,且該延伸部832可以與薄薄的該覆蓋面層831相連,以增加該防滲膠體83與扣合元件82的結合牢度。然而,該延伸部832在該二布帶81的另一面的成型性難以控制,常形成不規則形狀而影響美觀性。另,該延伸部832與該覆蓋面層831的厚薄程度相差太大,不只等待冷卻成型的時間有明顯差距,且形成該延伸部832之用料較多而成本較高。又,該習知防滲水拉鍊8的布帶81需要另外貼防水膠帶或是噴塗撥水劑,故整體製程較為冗長、繁瑣。 On the other hand, when the two rows of the fastening elements 82 are fastened to each other, the outermost end (tooth head) of the fastening element 82 on one of the aforementioned cloth strips 81 and the core portion 811 of the other aforementioned cloth strip 81 remain. There is a clear distance H, so that the impermeable gel 83 can form an extension 832 there, and the extension 832 can be connected to the thin cover layer 831 to increase the impermeable gel 83 and the fastening element 82 The binding fastness. However, the formability of the extension portion 832 on the other surface of the two cloth tapes 81 is difficult to control, and often forms an irregular shape, which affects the aesthetics. In addition, the thickness of the extension portion 832 and the covering surface layer 831 are too different, not only the time for waiting for the cooling and forming is significantly different, but also the material for forming the extension portion 832 is high and the cost is high. In addition, the cloth tape 81 of the conventional water-proof zipper 8 needs to be additionally affixed with waterproof tape or sprayed with water-repellent agent, so the overall manufacturing process is relatively tedious and cumbersome.
請參照第3圖,其係另一種習知的防滲水拉鍊9,該習知的防滲水拉鍊9具有二布帶91,該二布帶91的相鄰邊分別具有一蕊部911,各該蕊部911分別結合有一列扣合元件92。該習知的防滲水拉鍊9另具有一防滲膠體93係在該二列扣合元件92處於扣合狀態下,被押注覆蓋該二列扣合元件92及滲入該二列扣合元件92的間隙。類似於該習知的防滲水拉鍊9的一實施例已揭露於中華民國公開第201402032號「具有防滲結構之夾式扣合元件拉鍊」專利申請案當中。 Please refer to FIG. 3, which is another conventional water-proof zipper 9. The conventional water-proof zipper 9 has two cloth tapes 91, and adjacent edges of the two cloth tapes 91 each have a core portion 911. Each of the core portions 911 is respectively coupled with a row of fastening elements 92. The conventional watertight zipper 9 also has an anti-permeability gel 93 attached to the two rows of fastening elements 92 in a state of being fastened, and is bet to cover the two rows of fastening elements 92 and penetrate the two rows of fastening elements. Clearance of 92. An embodiment similar to the conventional water-tight zipper 9 has been disclosed in the patent application of ROC Publication No. 201402032 “Clip-type fastening element zipper with a water-tight structure”.
上述習知防滲水拉鏈9雖藉由使相扣合的該二列扣合元件92之間具有縫隙G,而可便於順暢操作該二列扣合元件92之扣合或分離;然而,在成型該防滲膠體93時,該防滲膠體93被押注滲入該二列扣合元件92間隙的部位,則有難以被刀具切割分離的問題。 Although the conventional water-proof zipper 9 has a gap G between the two rows of fastening elements 92 that are engaged with each other, it is convenient to smoothly operate the fastening or separation of the two rows of fastening elements 92; however, in When the impervious colloid 93 is molded, the impervious colloid 93 is injected and penetrated into the gap between the two rows of fastening elements 92, which is difficult to be cut and separated by a cutter.
此外,上述習知防滲水拉鏈9的其中一布帶91上的扣合元件92的最外端與另一布帶91的蕊部911之間同樣留有明顯的間距,且該防滲膠體93覆蓋在該二列扣合元件92上方的部位也是只有薄薄一層,故該習知防滲水拉鏈9同具有該防滲膠體93不同部位等待冷卻成型的時間有明顯差 距,以及形成該延伸部832之用料較多而成本較高等問題。又,該習知防滲水拉鍊9的布帶91同樣需要另外貼防水膠帶或是噴塗撥水劑,故整體製程較為冗長、繁瑣。 In addition, the outermost end of the fastening element 92 on one of the cloth strips 91 of the conventional water-proof zipper 9 and the core portion 911 of the other cloth strip 91 also have a clear space, and the water-proof gel The area covered by 93 above the two rows of fastening elements 92 is also only a thin layer, so the conventional water-proof zipper 9 has significantly different waiting time for different parts of the anti-seepage colloid 93 to cool down. Distance, and the cost of forming the extension 832 is high due to the large amount of materials used. In addition, the cloth tape 91 of the conventional water-proof zipper 9 also needs to be additionally affixed with waterproof tape or sprayed with water-repellent agent, so the overall manufacturing process is relatively tedious and cumbersome.
有鑑於此,習知的防滲水拉鏈確實仍有加以改善之必要。 In view of this, the conventional waterproof zippers do still need to be improved.

In this embodiment, the body 21 is a rectangle, and the head 22 is It has a rounded tip.
請參照第5、6圖所示,各該鍊齒2具有相連接的一上齒2a及一下齒2b,該上齒2a連接該布帶1的該上表面1a,該下齒2b連接該布帶1的該下表面1b。該上齒2a具有一緩降面24,使該上齒2a由該頸部23鄰近 該本體21處朝該頭部22的自由端遞減厚度。較佳地,該緩降面24可以成凸弧狀;該緩降面24可以連接該本體21及該頭部22的自由端;該緩降面24的二端高度差可以超過該上齒2a最大厚度的一半;另,該上齒2a的本體21可以短於該下齒2b的本體21。 5 and 6, each of the sprocket 2 has an upper tooth 2a and a lower tooth 2b connected to each other, the upper tooth 2a is connected to the upper surface 1a of the cloth tape 1, and the lower tooth 2b is connected to the cloth This lower surface 1b of the belt 1. The upper tooth 2a has a descent surface 24 such that the upper tooth 2a is adjacent to the neck 23 The body 21 decreases in thickness toward the free end of the head 22. Preferably, the slow-down surface 24 can be convexly curved; the slow-down surface 24 can be connected to the free end of the body 21 and the head 22; the height difference between the two ends of the slow-down surface 24 can exceed the upper tooth 2a. Half of the maximum thickness; in addition, the body 21 of the upper tooth 2a may be shorter than the body 21 of the lower tooth 2b.
此外,該上齒2a的頭部22及頸部23與該下齒2b的頭部22及頸部23可以形成錯位而不完全重合。在本實施例中,可選擇使該上齒2a的頭部22及頸部23偏向一側,並使該下齒2b的頭部22及頸部23偏向另一側,令該上齒2a的頭部22及頸部23與該下齒2b的頭部22及頸部23可以形成錯位而不完全重合對位;換言之,該上齒2a的頭部22及頸部23的其中一側緣E1位於該下齒2b的頭部22及頸部23的二側緣E2之間,該上齒2a的頭部22及頸部23的另一側緣E1並未與該下齒2b的頭部22及頸部23的任一側緣E2重合。又,該上齒2a的本體21在該蕊部11以外的部位可以重合對位於該下齒2b的本體21,使該數個鍊齒2可易於成型。 In addition, the head 22 and the neck 23 of the upper tooth 2a and the head 22 and the neck 23 of the lower tooth 2b may be misaligned and not completely overlap. In this embodiment, the head 22 and the neck 23 of the upper teeth 2a can be selected to be biased to one side, and the head 22 and the neck 23 of the lower teeth 2b are biased to the other side, so that the The head 22 and the neck 23 may be misaligned with the head 22 and the neck 23 of the lower tooth 2b and may not completely coincide with each other; in other words, one of the side edges E1 of the head 22 and the neck 23 of the upper tooth 2a Between the head 22 of the lower tooth 2b and the two side edges E2 of the neck 23, the head 22 of the upper tooth 2a and the other side edge E1 of the neck 23 are not connected to the head 22 of the lower tooth 2b And any side edge E2 of the neck 23 overlaps. In addition, the main body 21 of the upper teeth 2a can be overlapped with the main body 21 located on the lower teeth 2b at a position other than the core portion 11, so that the plurality of sprocket teeth 2 can be easily formed.
請參照第6、7圖所示,各該防滲膠體3係由熔融狀的高分子材料凝固而成,各該防滲膠體3凝固後具有彈性及阻水效果。該二防滲膠體3的成型方式,係先使該數個鍊齒2相扣合,再選擇例如押出法(extrusion)將熔融狀的高分子材料披覆於該數個鍊齒2的上齒2a與該二布帶1的上表面1a,及滲入該數個鍊齒2之間的縫隙G和其他部位的間隙;於熔融狀的高分子材料凝固後,再利用一刀具S沿該中線L切割,使凝固後的高分子材料可以分為該二防滲膠體3,且該二防滲膠體3的內側分別由一抵接面31相密貼。 Please refer to FIGS. 6 and 7, each of the impermeable colloids 3 is formed by solidifying a molten polymer material, and each of the impermeable colloids 3 has elasticity and water blocking effect after solidification. In the forming method of the two impermeable colloids 3, the plurality of fastener elements 2 are first engaged with each other, and then, for example, an extrusion method is used to coat the molten polymer material on the upper teeth of the plurality of fastener elements 2. 2a and the upper surface 1a of the two cloth belts 1 and the gap G infiltrated into the gaps between the plurality of sprocket teeth 2 and other parts; after the molten polymer material is solidified, a cutter S is used along the center line The L-cut allows the solidified polymer material to be divided into the two impervious colloids 3, and the inner sides of the two impervious colloids 3 are closely adhered by abutment surfaces 31, respectively.
其中,由於該數個鍊齒2僅於該中線L通過處形成密合,故該刀具S只要沿該中線L切割,即可順利將凝固後的高分子材料分為該二防滲膠體3,使該數個鍊齒2相分離時,該二防滲膠體3亦可順利分離(如第8圖所示)。再者,由於該數個鍊齒2由頭部22與頸部23相扣合時,各該鍊齒 2的頭部22自由端可以抵接相對布帶1的蕊部11,故該抵接處的間隙極小,使得成型該防滲膠體3時,該防滲膠體3不易通過該處而延伸到該二布帶1的下表面1b,故該防滲膠體3各部位的厚薄程度差距較小且不會突然變化太大,使該防滲膠體3的成型性較好控制,使用時也較不易損傷。另,由於凝固後的高分子材料覆蓋於該上齒2a之緩降面24,使得該二防滲膠體3可較平順地成型且具有較好的耐用性。 Among them, since the plurality of sprocket teeth 2 only form close contact with the middle line L, as long as the cutter S cuts along the middle line L, the solidified polymer material can be smoothly divided into the two impermeable colloids. 3. When the plurality of chain teeth 2 are separated from each other, the two impervious colloids 3 can also be smoothly separated (as shown in FIG. 8). Furthermore, when the plurality of sprocket elements 2 are fastened by the head 22 and the neck portion 23, each of the sprocket elements 2 The free end of the head 22 of 2 can abut the core portion 11 of the tape 1, so the gap at the abutment is extremely small, so that when the impermeable gel 3 is formed, the impermeable gel 3 cannot easily extend to the The lower surface 1b of the second cloth tape 1, so the thickness difference between the parts of the impervious colloid 3 is small and does not change suddenly, so that the moldability of the impervious colloid 3 is better controlled, and it is less likely to be damaged during use. . In addition, since the solidified polymer material covers the slow-down surface 24 of the upper teeth 2a, the two impermeable colloids 3 can be smoothly formed and have better durability.
詳言之,請參照第6、8圖所示,該防滲膠體3具有一第一覆齒部32至少覆蓋該鍊齒2的頸部23及本體21上端(本實施例的第一覆齒部32還有延伸覆蓋到該頭部22的一部分),前述的抵接面31形成在該第一覆齒部32的內側,即該第一覆齒部32較遠離該本體21的一端。其中,由於該第一覆齒部32覆蓋該上齒2a之緩降面24,故該第一覆齒部32可以朝該頭部22的自由端遞增厚度,除了具有提升該防滲膠體3的成型性及耐用性的功效外,更可增加該二抵接面31相抵接的面積,以提升整體阻水拉鍊的阻水效果。又,該緩降面24可以成凸弧狀,以兼具使該鍊齒2的頭部22、頸部23及該第一覆齒部32均可較易於成型的效果;特別是,當該緩降面24的二端高度差超過該上齒2a厚度的一半時,該第一覆齒部32成型時的厚薄變化較為平順,較容易控制該第一覆齒部32之成型性,使該第一覆齒部32不會厚度落差較大,此外,增加該二抵接面31相抵接面積的效果也會更為明顯。 In detail, please refer to FIG. 6 and FIG. 8. The impermeable gel 3 has a first tooth covering portion 32 covering at least the neck 23 of the sprocket 2 and the upper end of the body 21 (the first tooth covering in this embodiment). The portion 32 also extends to cover a portion of the head portion 22. The abutting surface 31 is formed on the inner side of the first tooth covering portion 32, that is, an end of the first tooth covering portion 32 farther from the body 21. Wherein, since the first tooth covering portion 32 covers the slow-down surface 24 of the upper tooth 2a, the first tooth covering portion 32 can increase in thickness toward the free end of the head portion 22, except that In addition to the effects of formability and durability, the abutting area of the two abutting surfaces 31 can be increased to improve the water blocking effect of the overall water blocking zipper. In addition, the slow-down surface 24 can be convexly curved, so that both the head 22, the neck 23, and the first tooth-covering portion 32 of the sprocket 2 can be easily formed. In particular, when the When the height difference between the two ends of the slow-down surface 24 exceeds half of the thickness of the upper tooth 2a, the thickness change of the first tooth-covering portion 32 is smoother, and it is easier to control the moldability of the first tooth-covering portion 32, so that The first tooth-covering portion 32 will not have a large thickness difference. In addition, the effect of increasing the contact area of the two contact surfaces 31 will be more obvious.
該防滲膠體3具有一第二覆齒部33連接該第一覆齒部32並覆蓋該鍊齒2的本體21外側。在本實施例中,該本體21的長度可以由下而上遞減,另搭配該上齒2a的本體21短於該下齒2b的本體21,使得該第二覆齒部33不會太薄,且該第二覆齒部33的體積可以由下而上遞增,從而賦予該第二覆齒部33較佳的強度,故該第二覆齒部33不易在使用一段時間後產生裂損或剝落,以提升整體阻水拉鍊之耐用度。 The impervious gel 3 has a second tooth covering portion 33 connected to the first tooth covering portion 32 and covering the outside of the body 21 of the sprocket 2. In this embodiment, the length of the body 21 can be reduced from bottom to top, and the body 21 with the upper teeth 2a is shorter than the body 21 of the lower teeth 2b, so that the second tooth covering portion 33 is not too thin. And the volume of the second tooth covering portion 33 can be increased from bottom to top, so as to give the second tooth covering portion 33 a better strength, so the second tooth covering portion 33 is not easy to be cracked or peeled off after a period of use. To improve the durability of the overall water blocking zipper.
該防滲膠體3可以具有一覆帶部34覆蓋該布帶1的上表面1a,該覆帶部34的一端連接該第二覆齒部33,另一端較佳連接至該布帶1的下表面1b,使該布帶1的外側可以被該覆帶部34所包覆。如此,不僅可使該布帶1的外側具有阻水效果,更可使該防滲膠體3不易從布帶1的外側翻起,以提升該阻水拉鍊之耐用度。再且,該布帶1可以在成型該防滲膠體3時即具有防水效果,而不需要另外再安排製程來賦予該布帶1防水效果,故可簡化整體的製程。 The impermeable gel 3 may have a tape covering portion 34 covering the upper surface 1 a of the tape 1. One end of the tape covering portion 34 is connected to the second tooth covering portion 33, and the other end is preferably connected to the lower portion of the tape 1. The surface 1b allows the outer side of the tape 1 to be covered by the tape covering portion 34. In this way, not only the outer side of the cloth tape 1 can have a water blocking effect, but also the impermeable gel 3 can not be easily lifted from the outer side of the cloth tape 1 to improve the durability of the water blocking zipper. Furthermore, the cloth tape 1 can have a waterproof effect when the impermeable gel 3 is formed, and it is not necessary to arrange another manufacturing process to give the cloth tape 1 a waterproof effect, so the overall manufacturing process can be simplified.
請參照第6、9、10圖,據由前述結構,藉由拉動該拉頭4可以使該數個鍊齒2相扣合或相分離。當該數個鍊齒2相扣合時,該二防滲膠體3的該抵接面31可以緊密貼合,且該數個鍊齒2間的間隙G亦由該二防滲膠體3所填補,使得液體無法由該阻水拉鍊之一表面通過該數個鍊齒2間而滲透至另一表面。特別是,由於該數個鍊齒2僅於該中線L通過處形成密合,其餘部位具有間隙G,故只要沿該中線L切割即可順利將凝固後的高分子材料分為該二防滲膠體3,並可使該數個鍊齒2順暢地相扣合或分離。再且,由於本實施例選擇使各該鍊齒2的頭部22自由端抵接相對布帶1的蕊部11,使得該防滲膠體3只有少部分會延伸到二布帶1的另一面,且該防滲膠體3各部位的厚薄程度不會相差太大,使該防滲膠體3的成型性較好控制,使用時也較不易損傷。又,由於本實施例選擇使該上齒2a的頭部22及頸部23與該下齒2b的頭部22及頸部23形成錯位而不完全重合,故該數個鍊齒2相扣合時,該數個鍊齒2可以由相錯位的部位相互擋止;如此,該阻水拉鍊在受到外力而彎折時,該數個鍊齒2仍可穩固地維持相扣合,不易因彎折而使該數個鍊齒2相錯位滑開而成開放狀。 Please refer to FIGS. 6, 9, and 10. According to the foregoing structure, the plurality of sprocket teeth 2 can be engaged with each other or separated from each other by pulling the slider 4. When the plurality of sprocket teeth 2 are engaged with each other, the abutment surface 31 of the two impervious colloids 3 can be closely attached, and the gap G between the plurality of sprocket teeth 2 is also filled by the two impervious colloids 3. , So that liquid cannot penetrate from one surface of the water-blocking zipper to the other surface through the plurality of chain teeth 2. In particular, since the plurality of sprocket teeth 2 only form close contact with the middle line L and the rest has a gap G, the solidified polymer material can be smoothly divided into the two as long as it is cut along the center line L. The impervious colloid 3 can smoothly engage or separate the plurality of sprocket teeth 2. Furthermore, since the free end of the head 22 of each sprocket 2 is selected to abut the core portion 11 of the opposite tape 1 in this embodiment, only a small part of the impermeable gel 3 will extend to the other side of the second tape 1 In addition, the thickness of each part of the impermeable colloid 3 will not be too different, so that the moldability of the impermeable colloid 3 is better controlled, and it is less likely to be damaged during use. In addition, in this embodiment, the head 22 and the neck 23 of the upper tooth 2a are selected to be misaligned with the head 22 and the neck 23 of the lower tooth 2b, so that the plurality of sprocket 2 are interlocked. At this time, the plurality of sprocket teeth 2 can be stopped from each other by dislocated parts; in this way, when the water blocking zipper is bent by an external force, the plurality of sprocket teeth 2 can still maintain the interlocking engagement firmly, and it is not easy to bend. When folded, the two sprocket teeth are slipped and shifted apart to form an open shape.
值得一提的是,請參照第11圖所示,各該防滲膠體3可以另具有數個變形空間35,該數個變形空間35大致上分別對位於同一布帶1上 的任二相鄰鍊齒2之間。在本實施例中,該數個變形空間35主要位於該第一覆齒部32,各該變形空間35的一端未延伸至該抵接面31,另一端則較佳延伸至該第二覆齒部33;如此,可更進一步地提升各該防滲膠體3的彈性變形能力,使整體阻水拉鍊可更為柔軟,不易因設有該二防滲膠體3而過於僵硬,且兼可提升拉動該拉頭4(標示於第10圖中)以控制該數個鍊齒2相扣合或相分離時的順暢度。 It is worth mentioning that, referring to FIG. 11, each of the impermeable gels 3 may have a plurality of deformation spaces 35, and the plurality of deformation spaces 35 are generally located on the same tape 1 respectively. Between any two adjacent sprocket 2. In this embodiment, the plurality of deformation spaces 35 are mainly located in the first tooth covering portion 32, one end of each of the deformation spaces 35 does not extend to the abutment surface 31, and the other end preferably extends to the second tooth covering.部 33; In this way, the elastic deformation ability of each of the impervious gels 3 can be further improved, so that the overall water-blocking zipper can be softer, it is not easy to be too stiff because of the two impervious gels 3, and it can also improve pulling The slider 4 (labeled in FIG. 10) is used to control the smoothness of the plurality of sprocket teeth when the two phases are engaged or separated.
請參照第12圖所示,其係本發明阻水拉鍊的第二實施例,各該鍊齒2的該上齒2a及該下齒2b可以分別成左右對稱,該上齒2a與該下齒2b可以形成偏移而不完全重合,使得該數個鍊齒2可以易於成型,且該數個鍊齒2相扣合時,該數個鍊齒2可以由相錯位的部位相互擋止;如此,該阻水拉鍊在受到外力而彎折時,該數個鍊齒2仍可穩固地維持相扣合,不易因彎折而使該數個鍊齒2相錯位滑開而成開放狀。較佳地,該頭部22的下表面可以具有一凹槽25,該鍊齒2的二側可以分別具有一肩部26,該肩部26連接該本體21並凸伸至該二蕊部11之間;如此,當該數個鍊齒2相扣合時,各該鍊齒2的肩部26可以穿入相交錯扣合的另一鍊齒2的凹槽25,以更進一步地提升該數個鍊齒2的結合穩固性,使該阻水拉鍊可穩固維持閉合狀。 Please refer to FIG. 12, which is a second embodiment of the water blocking zipper according to the present invention. The upper teeth 2 a and the lower teeth 2 b of each sprocket 2 may be left and right symmetrical respectively, and the upper teeth 2 a and the lower teeth are symmetrical. 2b may form an offset and not completely overlap, so that the plurality of sprocket teeth 2 can be easily formed, and when the plurality of sprocket teeth 2 are engaged with each other, the plurality of sprocket teeth 2 can be stopped by each other by dislocated parts; When the water-blocking zipper is bent under external force, the plurality of sprocket teeth 2 can still maintain the phase engagement firmly, and it is not easy for the plurality of sprocket teeth 2 to slip apart due to bending and become open. Preferably, the lower surface of the head 22 may have a groove 25, and two sides of the sprocket 2 may each have a shoulder portion 26, which is connected to the body 21 and protrudes to the second core portion 11 In this way, when the plurality of sprocket teeth 2 are engaged with each other, the shoulders 26 of each sprocket teeth 2 can penetrate into the grooves 25 of the other sprocket teeth 2 that are interlacedly engaged to further enhance the The combination and stability of several sprocket teeth 2 enables the water blocking zipper to maintain a closed shape firmly.
綜上所述,本發明的阻水拉鍊,該防滲膠體可易於被該刀具切割分離,且該數個鍊齒可順暢地相扣合或分離;另外,由於該防滲膠體只有少部分會延伸到該二布帶的另一面,且該防滲膠體各部位的厚薄程度不會相差太大,故該防滲膠體的成型性較好控制,使用時也較不易損傷;再且,在受到外力而彎折時,該阻水拉鍊仍可穩固地成閉合狀,不會因彎折而使鍊齒相錯位滑開而成開放狀。再且,該阻水拉鍊可以一併成型布帶及鍊齒的防水結構以簡化製程。 In summary, in the water blocking zipper of the present invention, the impervious gel can be easily cut and separated by the cutter, and the plurality of sprocket teeth can be smoothly engaged or separated; in addition, only a small part of the impervious gel can Extending to the other side of the two cloth tapes, and the thickness of each part of the impervious colloid will not be much different, so the moldability of the impervious colloid is better controlled, and it is less likely to be damaged during use. When bent by external force, the water-blocking zipper can still be firmly closed, and the chain teeth will not slip out of position due to bending and become open. Furthermore, the water-blocking zipper can form a waterproof structure of the tape and the chain teeth together to simplify the manufacturing process.
