於拉鏈鏈齒於拉鏈滑件內之鏈齒通路移動時，藉由鏈齒插通路之壁面而導引拉鏈鏈齒，從而確保穩定之滑動動作。若拉鏈鏈齒之大小相對於鏈齒通路之空間過大，則拉鏈鏈齒與鏈齒插通路之壁面之間的摩擦變大，從而滑動性惡化。另一方面，若拉鏈鏈齒相對於鏈齒通路之空間過小，則拉鏈鏈齒於鏈齒通路內之位置穩定性降低而導致拉鏈鏈齒之移動變得不穩定，從而有可能引起拉鏈鏈齒之嚙合不良。 When the zipper element moves in the sprocket path in the zipper slider, the zipper element is guided by the wall surface of the sprocket insertion passage, thereby ensuring a stable sliding motion. If the size of the fastener element is too large with respect to the space of the element path, the friction between the fastener element and the wall surface of the element insertion passage becomes large, and the sliding property is deteriorated. On the other hand, if the space of the fastener element with respect to the element tooth passage is too small, the positional stability of the fastener element in the element tooth passage is lowered, and the movement of the fastener element becomes unstable, which may cause the fastener element to be zippered. Poor meshing.

鏈齒通路之空間寬廣度與拉鏈鏈齒之大小係用以確保順利的滑動動作之研究項目之一，但於樹脂製拉鏈滑件中，藉由由樹脂射出後之冷卻步驟所致之熱收縮的影響，嚙合口之上下寬度相對於連結柱側之左右之導入口的上下寬度而變窄。就拉鏈之操作性之觀點而言，此情況有時會成為問題。 The breadth of the sprocket path and the size of the sprocket are one of the research items to ensure a smooth sliding action, but in the resin zipper slider, the heat shrinkage caused by the cooling step after the resin is ejected The influence of the upper and lower widths of the engaging opening is narrowed with respect to the upper and lower widths of the left and right introduction ports on the side of the connecting post. This situation sometimes becomes a problem in terms of the operability of the zipper.

如圖1所示，拉鏈90包含一對拉鏈鏈帶100，且還包含用以使一對拉鏈鏈帶100開閉之樹脂製之拉鏈滑件500，該等一對拉鏈鏈帶100包含左側拉鏈鏈帶101與右側拉鏈鏈帶102。各拉鏈鏈帶100包含：拉鏈鏈布200；拉鏈鏈布200之對向側緣之芯繩210；及設置於芯繩210上之拉鏈鏈齒400。拉鏈鏈齒400沿各拉鏈鏈帶102之長度方向而設置有複數個，且各個拉鏈鏈齒400各自獨立。 As shown in FIG. 1, the zipper 90 includes a pair of zipper tapes 100, and further includes a resin zipper slider 500 for opening and closing a pair of zipper tapes 100, the pair of zipper tapes 100 including a left zipper chain. Belt 101 and right side zipper tape 102. Each of the zipper chain belts 100 includes: a zipper chain cloth 200; a core rope 210 opposite to the side edges of the zipper chain cloth 200; and a zipper element 400 disposed on the core rope 210. The zipper elements 400 are provided in plural along the length direction of each of the zipper chain belts 102, and each of the zipper elements 400 is independent of each other.

拉鏈鏈布200係梭織物或針織物，且係具有靈活性之片材。拉鏈鏈齒400並非必須限於此，其係藉由聚醯胺、聚縮醛、聚丙烯、聚對苯二甲酸丁二醇酯等合成樹脂之射出成形而與拉鏈鏈布200之對向側緣一體化之樹脂成形部。拉鏈滑件500亦與拉鏈鏈齒400同樣地係藉由合成樹脂之射出成形而成形之成形品。 The zipper chain cloth 200 is a woven fabric or a knitted fabric, and is a sheet having flexibility. The fastener element 400 is not necessarily limited thereto, and is formed by injection molding of a synthetic resin such as polyamine, polyacetal, polypropylene, or polybutylene terephthalate with the opposite side edges of the fastener stringer 200. Integrated resin forming section. Similarly to the fastener element 400, the zipper slider 500 is a molded article formed by injection molding of a synthetic resin.

如圖1中模式性所示，藉由拉鏈滑件500向前方移動而使左右之拉鏈鏈齒400彼此自分離之狀態變為嚙合狀態，藉此，左側拉鏈鏈帶101與右側拉鏈鏈帶102閉鎖。於圖1所示之較拉鏈滑件500靠後方之左側拉鏈鏈帶101與右側拉鏈鏈帶102之閉鎖部位，固定於左側拉鏈鏈布201之芯繩211之左側拉鏈鏈齒401配置於被固定於右側拉鏈鏈布202之芯繩212且隔開一個拉鏈鏈齒400之量之間隔而前後相鄰的右側拉鏈鏈齒402之間。同樣地，固定於右側拉鏈鏈布202之芯繩212之右側拉鏈 鏈齒402配置於被固定於左側拉鏈鏈布201之芯繩211且隔開一個拉鏈鏈齒400之量之間隔而前後相鄰的左側拉鏈鏈齒401之間。 As schematically shown in FIG. 1, the left and right fastener elements 400 are brought into an engaged state by the zipper slider 500 moving forward, whereby the left side fastener chain 101 and the right side fastener string 102 are separated. Blocked. The left side fastener element 101 of the left side fastener chain 201 is fixed to the left side fastener element 401 of the left side fastener chain 201, and is fixed to the left side fastener element 401 of the left side fastener chain 201. The core string 212 of the right side fastener zipper 202 is spaced between the right and left zipper elements 402 adjacent to each other at intervals of one of the fastener elements 400. Similarly, the right side zipper of the core cord 212 fixed to the right side fastener chain 202 The sprocket 402 is disposed between the left and right fastener elements 401 which are fixed to the core stalk 211 of the left zipper chain 201 and spaced apart by one of the fastener elements 400.

於左右之拉鏈鏈帶100嚙合時，左右之拉鏈鏈齒400於前後方向交替配置於同一直線上。若更具體地說明，則拉鏈鏈齒400包含：前端部，其於拉鏈鏈布寬度方向上最遠離拉鏈鏈布200；及基端部，其位於前端部之相反側、且拉鏈鏈齒400中最靠近拉鏈鏈布內方側；以使右側拉鏈鏈齒402之前端部與左側拉鏈鏈齒401之基端部於前後方向配置於同一直線上，且使左拉鏈鏈齒401之前端部與右側拉鏈鏈齒402之基端部於前後方向位於同一直線上的方式交替配置。該點與先前之一般的鋸齒狀配置之拉鏈鏈齒之態樣顯著不同。進而，各個拉鏈鏈齒400隔開一個拉鏈鏈齒400之量之間隔而設置於各拉鏈鏈布200之對向側緣210，藉此可確保各拉鏈鏈帶100之較高之柔軟性。 When the left and right fastener stringers 100 are engaged, the left and right fastener elements 400 are alternately arranged on the same straight line in the front-rear direction. More specifically, the fastener element 400 includes a front end portion that is farthest from the fastener chain cloth 200 in the width direction of the fastener chain fabric, and a base end portion that is located on the opposite side of the front end portion and in the fastener element 400. The inner side of the front side of the fastener element 402 and the left side fastener element 401 are disposed on the same straight line in the front-rear direction, and the front end and the right side of the left fastener element 401 are disposed on the same side. The base end portions of the fastener element 402 are alternately arranged in such a manner that the base end portions are on the same straight line in the front-rear direction. This point is significantly different from the previous general zigzag configuration of the zipper teeth. Further, each of the fastener element 400 is disposed at an opposite side edge 210 of each of the fastener chains 200 at intervals of one fastener element 400, whereby the high flexibility of each fastener chain 100 can be ensured.

如圖2至圖4所示，於各拉鏈鏈齒400之前端部設置有鏈布***凹部450。因此，在固定於右側拉鏈鏈布202之於前後橫向排列之右側拉鏈鏈齒402之間配置左側拉鏈鏈齒401時，右側拉鏈鏈布202之芯繩212***至左側拉鏈鏈齒401之鏈布***凹部450。藉此，如圖1中模式性所示，成為左側拉鏈鏈齒401與右側拉鏈鏈齒402於前後方向彼此交錯地配置於同一直線上之狀態。若參照本說明則可明確瞭解，於固定於左側拉鏈鏈布201之於前後橫向排列之左側拉鏈鏈齒401之間配置右側拉鏈鏈齒402時，左側拉鏈鏈布201之芯繩211***至右側拉鏈鏈齒402之鏈布***凹部450中。 As shown in FIGS. 2 to 4, a link insertion recess 450 is provided at an end portion of each of the fastener elements 400. Therefore, when the left side fastener element 401 is disposed between the right side fastener element 402 and the right side fastener element 402 which are fixed to the right side fastener chain 202, the core string 212 of the right side fastener chain 202 is inserted into the chain of the left side fastener element 401. The recess 450 is inserted. As a result, as shown in FIG. 1 , the left side fastener element 401 and the right side fastener element 402 are arranged in a state in which they are alternately arranged on the same straight line in the front-rear direction. As can be clearly understood from the description, when the right side fastener element 402 is disposed between the left side fastener element 401 which is fixed to the left side fastener chain 201 and is arranged laterally in the front and rear direction, the core string 211 of the left side fastener chain 201 is inserted to the right side. The chain of fastener elements 402 is inserted into the recess 450.

如圖1至圖4所示，於各拉鏈鏈齒400之前後側面設置有卡合部460。於圖1所示之上述嚙合狀態下，左側拉鏈鏈齒401之後側之卡合部460卡合於鄰接之右側拉鏈鏈齒402之前側之卡合部460，且右側拉鏈鏈齒402之後側之卡合部460卡合於鄰接之左側拉鏈鏈齒401之前側之卡合部460。於此種態樣下，左側拉鏈鏈齒401與右側拉鏈鏈齒402 之卡合係於前後直線狀地連續，藉此可對拉鏈90賦予對抗左右方向之拉伸之耐性。 As shown in FIGS. 1 to 4, an engaging portion 460 is provided on the front side surface of each of the fastener elements 400. In the above-mentioned meshing state shown in FIG. 1, the engaging portion 460 on the rear side of the left side fastener element 401 is engaged with the engaging portion 460 on the front side of the adjacent right side fastener element 402, and the rear side of the right side fastener element 402 is The engaging portion 460 is engaged with the engaging portion 460 on the front side of the adjacent left side fastener element 401. In this aspect, the left side zipper element 401 and the right side zipper element 402 The engagement is continuous linearly in the front and rear directions, whereby the fastener 90 can be imparted with resistance against stretching in the left-right direction.

如圖2至圖4所示，本例之拉鏈鏈齒400包含：基部410，其固定於芯繩210；及頭部420，其與基部410相比較而位於前端側，且設置有鏈布***凹部450。拉鏈鏈齒400還包含設計部430，該設計部430設置於遍及基部410與頭部420之範圍。設計部430藉由弧狀之曲面而包圍全周。拉鏈鏈齒400具有沿固定有該拉鏈鏈齒400之芯繩210之前後寬度、及自固定有該拉鏈鏈齒400之芯繩210朝向對象側之芯繩210之左右寬度，且左右寬度構成得稍大於前後寬度。換言之，設計部430呈現將於鏈布寬度方向及鏈布長度方向分別彎曲為凸狀之球體狀之珠粒分割為兩部分而得之一半珠粒形狀。 As shown in FIG. 2 to FIG. 4, the fastener element 400 of this embodiment includes a base 410 fixed to the core string 210, and a head 420 which is located on the front end side of the base portion 410 and is provided with a chain cloth insertion. The recess 450. The zipper element 400 also includes a design portion 430 that is disposed throughout the range of the base 410 and the head 420. The design portion 430 surrounds the entire circumference by a curved curved surface. The zipper element 400 has a width along the front and rear widths of the core cord 210 to which the fastener element 400 is fixed, and a left and right width of the core cord 210 facing the object side from the core cord 210 to which the fastener element 400 is fixed, and the left and right widths are formed. Slightly larger than the front and rear width. In other words, the design portion 430 has a spherical shape in which the spherical beads which are curved in a convex shape in the chain width direction and the longitudinal direction of the chain are divided into two parts to obtain a one-half-bead shape.

如圖1所示，左右之拉鏈鏈齒400於前後方向直線狀地連續之嚙合狀態下，球體、直接而言珠粒狀之拉鏈鏈齒400於前後直線狀地連續，作為整體看起來如一連串之念珠。其與此前一般的拉鏈鏈齒之嚙合狀態之形態根本性不同，不僅賦予設計上之嶄新性，而且對拉鏈鏈帶100賦予較高之靈活性。再者，本領域技術人員或許可立即理解，但設計部430之形狀並不限於圖中例示之左右較長之珠粒之一半形狀，例如，亦可為如三棱錐或四棱錐般具有朝前端點傾斜之3個以上之平面的部分。 As shown in Fig. 1, in the state in which the left and right fastener elements 400 are continuously meshed in a straight line in the front-rear direction, the spherical body and the bead-shaped fastener element 400 are linearly continuous in the front and rear, and appear as a series as a whole. Rosary. The shape of the meshing state of the conventional zipper sprocket is fundamentally different, which not only imparts a new design, but also gives the zipper chain 100 a higher flexibility. Further, those skilled in the art may understand immediately, but the shape of the design portion 430 is not limited to one half shape of the left and right beads exemplified in the drawing, and may be, for example, a front end such as a triangular pyramid or a quadrangular pyramid. The portion of the plane that is inclined by more than three points.

設置於拉鏈鏈齒400上之前後之各卡合部460包含卡合面465，該卡合面465面向設置有該等各卡合部460之拉鏈鏈齒400所固定之鏈布側緣的芯繩210。如自圖4觀察而可理解般，卡合面465位於較鏈布***凹部450之底面455靠芯繩210側，藉此，卡合面465並未藉由鏈布***凹部450而分割，從而可於上下確保充分範圍之卡合區域。左右之拉鏈鏈齒400之各卡合部460彼此之卡合係為了拉鏈90於左右方向之之耐性而設置，故而並非必須限於此，但如圖示般各卡合面465較理想 為相對於左右方向而正交之平面。 Each of the engaging portions 460 disposed on the front and rear of the fastener element 400 includes an engaging surface 465 facing the core of the side edge of the chain to which the fastener elements 400 of the engaging portions 460 are disposed. Rope 210. As can be understood from FIG. 4 , the engaging surface 465 is located on the side of the core cord 210 than the bottom surface 455 of the chain insertion recess 450 , whereby the engaging surface 465 is not divided by the chain insertion recess 450 , thereby A sufficient range of engagement areas can be secured up and down. The engagement of the engaging portions 460 of the left and right fastener elements 400 is provided for the resistance of the zipper 90 in the left-right direction. Therefore, it is not necessarily limited thereto, but each of the engaging surfaces 465 is ideal as illustrated. It is a plane orthogonal to the left and right direction.

如圖5所示，於左右之拉鏈鏈齒400處於嚙合狀態時，左側拉鏈鏈齒401之後側之卡合部460的卡合面465與右側拉鏈鏈齒402之前側之卡合部460的卡合面465面接觸，且右側拉鏈鏈齒402之後側之卡合部460的卡合面465與未圖示之左側拉鏈鏈齒401之前側之卡合部460的卡合面465面接觸。於該態樣下，左側拉鏈鏈齒401與右側拉鏈鏈齒402之各卡合面465之面接觸係於前後直線狀地排列，藉此可對拉鏈90賦予對抗左右方向之拉伸之耐性。 As shown in FIG. 5, when the left and right fastener elements 400 are in the engaged state, the engagement surface 465 of the engaging portion 460 on the rear side of the left side fastener element 401 and the engagement portion 460 of the front side of the right side fastener element 402 are engaged. The engaging surface 465 is in surface contact, and the engaging surface 465 of the engaging portion 460 on the rear side of the right side fastener element 402 is in surface contact with the engaging surface 465 of the engaging portion 460 on the front side of the left side fastener element 401 (not shown). In this aspect, the surface contact between the left side fastener element 401 and the engagement surface 465 of the right side fastener element 402 is linearly arranged in the front-rear direction, whereby the fastener 90 can be imparted with resistance against stretching in the left-right direction.

再者，於圖2至圖5所示之情形時，拉鏈鏈齒400固定於單一芯繩，但拉鏈鏈齒400亦可如圖6所示固定於上下鄰接地設置有更小徑之2個芯部之芯繩。揭示有關於圖6之技術之專利文獻2的全部內容於本說明書中藉由參照而併入於此。 Furthermore, in the case shown in FIGS. 2 to 5, the fastener element 400 is fixed to a single core rope, but the fastener element 400 may be fixed to the upper and lower adjacent ones with two smaller diameters as shown in FIG. Core rope of the core. The entire contents of Patent Document 2, which discloses the technology of FIG. 6, are incorporated herein by reference.

上翼板510具有與下翼板520對向之對向主面515。下翼板520具有與上翼板510對向之對向主面525。藉由該一對對向主面515、525而將設置於滑件主體540之鏈齒通路70自上下封閉。一對對向主面515、525基本上係疊合構成，但於在拉鏈鏈齒400之設計部430滑動之上翼板510形成有***部600之方面不同。 The upper wing plate 510 has a main surface 515 opposite to the lower wing plate 520. The lower wing panel 520 has a facing main surface 525 opposite the upper wing panel 510. The sprocket passage 70 provided in the slider body 540 is closed from the upper and lower sides by the pair of opposing main faces 515, 525. The pair of opposing main faces 515, 525 are substantially superposed, but differ in that the design portion 430 of the fastener element 400 slides over the upper flange 510 in which the ridges 600 are formed.

如圖8(P1)部分所示，左側上部凸緣部511及右側上部凸緣部521包含相互對向之內側面52。左側上部凸緣部511包含與右側上部凸緣部521對向之內側面513。右側上部凸緣部521包含與左側上部凸緣部511對向之內側面523。左側下部凸緣部512及右側下部凸緣部522包含相互對向之內側面51。左側下部凸緣部512包含與右側下部凸緣部522對向之內側面514。右側下部凸緣部522包含與左側下部凸緣部512對向之內側面524。藉由左右凸緣部550之對向之內側面51、52而將設置於滑件主體540之鏈齒通路70自左右封閉。 As shown in part (P1) of Fig. 8, the left upper flange portion 511 and the right upper flange portion 521 include inner side faces 52 that face each other. The left upper flange portion 511 includes an inner side surface 513 that faces the right upper flange portion 521. The right upper flange portion 521 includes an inner side surface 523 that faces the left upper flange portion 511. The left lower flange portion 512 and the right lower flange portion 522 include inner side faces 51 that face each other. The left lower flange portion 512 includes an inner side surface 514 that faces the right lower flange portion 522. The right lower flange portion 522 includes an inner side surface 524 that faces the left lower flange portion 512. The sprocket passages 70 provided in the slider body 540 are closed from the left and right by the inner side faces 51, 52 of the right and left flange portions 550.

如圖8(P2)及(P3)部分所示，於滑件主體540之前端側，於連結柱530之左右設置有***部600。***部600配置於連結柱530與左或右之凸緣部550之間。根據該構成，即便於考慮樹脂之熱收縮之影響而較 寬地設定上翼板510與下翼板520之間隔之情形時，亦可充分地限制拉鏈鏈齒400於滑件主體540之前端部之滑件主體540內之移位，可使拉鏈鏈齒400於滑件主體540內之移動順利化。可於受到充分限制之鏈齒通路70內抑制拉鏈鏈齒400之滾動，從而可確保拉鏈滑件500順利滑動。 As shown in parts (P2) and (P3) of FIG. 8, on the front end side of the slider main body 540, a swelled portion 600 is provided on the right and left sides of the connecting post 530. The raised portion 600 is disposed between the connecting post 530 and the left or right flange portion 550. According to this configuration, even when considering the influence of heat shrinkage of the resin When the spacing between the upper wing 510 and the lower wing 520 is widely set, the displacement of the fastener element 400 in the slider body 540 at the front end of the slider body 540 can be sufficiently restricted, and the fastener element can be made. The movement of 400 within the slider body 540 is smooth. The rolling of the fastener element 400 can be suppressed in the sufficiently restricted sprocket passage 70, thereby ensuring smooth sliding of the zipper slider 500.

本實施形態中，以使樹脂熱收縮後之嚙合口之上下寬度適合於拉鏈鏈齒之上下高度的方式設計拉鏈滑件。若不設置***部600，則拉鏈滑件之導入口之上下寬度大於拉鏈鏈齒之上下高度而產生間隙。亦即，導入口側之上下寬度之尺寸大於嚙合口側之上下寬度。該結果為，拉鏈鏈齒於滑件之導入口側之移位量變大，從而無法良好地限制拉鏈鏈齒於滑件內之移動，視情形而有於拉鏈鏈齒內產生拉鏈鏈齒滾動之虞。 In the present embodiment, the zipper slider is designed such that the upper and lower widths of the engaging opening after heat shrinking of the resin are suitable for the upper and lower heights of the fastener elements. If the swelled portion 600 is not provided, the upper and lower widths of the introduction opening of the zipper slider are larger than the upper and lower heights of the fastener elements, and a gap is generated. That is, the size of the upper and lower widths of the inlet side is larger than the upper and lower widths of the inlet side. As a result, the amount of displacement of the fastener element on the side of the inlet of the slider becomes large, so that the movement of the fastener element in the slider cannot be well restricted, and the fastener element is rolled in the fastener element as the case may be. Hey.

於如本實施形態般拉鏈鏈齒400包含半珠粒狀之設計部430之情形時，有藉由設計部430之外周曲面而拉鏈鏈齒400易於在滑件主體540內滾動之虞。本實施形態中，鑒於該點，於拉鏈鏈齒400之設計部430滑動之上翼板510之對向主面515設置有***部600。藉此限制上述拉鏈鏈齒400之滾動。當然，於本實施形態中作為追加或替代，亦可於下翼板520設置***部600。 In the case where the fastener element 400 includes the semi-bead-shaped design portion 430 as in the present embodiment, the fastener element 400 is easily rolled in the slider main body 540 by the outer peripheral curved surface of the design portion 430. In the present embodiment, in view of this point, the design portion 430 of the fastener element 400 slides on the opposing main surface 515 of the upper blade 510 with the raised portion 600. Thereby, the rolling of the above-mentioned fastener element 400 is restricted. Of course, in the present embodiment, the ridge portion 600 may be provided in the lower blade 520 as an addition or replacement.

再者，於如專利文獻1或專利文獻2般之形狀之拉鏈鏈齒之情形時，拉鏈鏈齒易於以前後方向為軸旋轉，故而可能產生如下情況，即於導入口側卡住，從而滑動動作變得不順利。 Further, in the case of the fastener element of the shape of the patent document 1 or the patent document 2, the fastener element is easy to rotate in the front-back direction, and it may become the case that it is stuck in the inlet side, and it slides. The action didn't go well.

根據圖8之(P2)及(P3)部分而可明確瞭解，***部600於連結柱530之左側包含左側***部601，且於連結柱530之右側包含右側***部602。以對向主面515為基準時之左側***部601之高度與右側***部602之高度相同，但並非必須限於該態樣。例如，若左右拉鏈鏈齒400之設計部430之形狀或高度不同，則亦可與此對應而個別地調整左 右***部600之高度。 As is clear from parts (P2) and (P3) of FIG. 8 , the raised portion 600 includes a left side ridge 601 on the left side of the connecting post 530 and a right side ridge 602 on the right side of the connecting post 530 . The height of the left side ridge 601 when the opposing main surface 515 is used as the reference is the same as the height of the right side ridge 602, but it is not necessarily limited to this aspect. For example, if the shape or height of the design portion 430 of the left and right fastener elements 400 is different, the left side may be individually adjusted accordingly. The height of the right ridge 600.

***部600較佳為以使滑件主體540之導入口之開口尺寸變窄之方式設置。如圖9直接顯示般，於左側凸緣部551之前端551f與連結柱530之左側面531之間亦存在左側***部601，且於右側凸緣部552之前端552f與連結柱530之右側面532之間亦存在右側***部602。換言之，***部600係配置於較各左右凸緣部550之前端靠前方。 The raised portion 600 is preferably provided to narrow the opening of the inlet of the slider body 540. As shown directly in FIG. 9, there is also a left side ridge 601 between the front end 551f of the left flange portion 551 and the left side surface 531 of the coupling post 530, and the front end 552f of the right flange portion 552 and the right side of the coupling post 530. There is also a right side ridge 602 between 532. In other words, the raised portion 600 is disposed forward of the front end of each of the right and left flange portions 550.

根據圖8之(P2)及(P3)部分而可明確瞭解，***部600較佳為包含面向連結柱530之態樣之傾斜面610。又，***部600於傾斜面610與和***部600相鄰之凸緣部550之間包含平坦面620。傾斜面610連接對向主面515與平坦面620之間，又以面向連結柱530之方式緩而淺地傾斜。平坦面620處於對向主面515稍向下方移位之態樣，且相對於對向主面515而平行。 It is clear from the parts (P2) and (P3) of FIG. 8 that the raised portion 600 preferably includes an inclined surface 610 that faces the connecting post 530. Further, the raised portion 600 includes a flat surface 620 between the inclined surface 610 and the flange portion 550 adjacent to the raised portion 600. The inclined surface 610 is connected between the opposing main surface 515 and the flat surface 620, and is gently tilted so as to face the connecting post 530. The flat surface 620 is displaced slightly downward from the opposing major surface 515 and is parallel with respect to the opposing major surface 515.

如圖8及圖9所示，於連結柱530與各***部601間存在上翼板510之對向主面515。上翼板510之對向主面515遍及滑件主體540之導入口與嚙合口之間而存在。圖8(P3)所示之處於連結柱530與***部600間之未設置***部600之部位之上下翼板間的上下尺寸，寬於圖8(P1)所示之滑件主體540之嚙合口之上下翼板間的上下尺寸。上翼板510之對向主面515係自滑件主體540之導入口側向嚙合口側緩慢地下降之傾斜面。圖8(P1)所示之嚙合口之上下尺寸係與圖8(P3)所示之***部600之導入口之上下尺寸大體一致，但較理想為大於此。 As shown in FIGS. 8 and 9, the opposing main surface 515 of the upper blade 510 is present between the connecting post 530 and each of the raised portions 601. The opposing major faces 515 of the upper wing 510 are present between the inlet and the engagement opening of the slider body 540. 8(P3) shows the upper and lower dimensions between the lower wing of the portion between the connecting post 530 and the raised portion 600 where the raised portion 600 is not provided, and is wider than the meshing of the slider main body 540 shown in FIG. 8 (P1). The upper and lower dimensions between the lower and upper wings of the mouth. The opposing main surface 515 of the upper blade 510 is an inclined surface that gradually descends from the introduction port side of the slider main body 540 toward the engagement port side. The upper and lower dimensions of the engaging opening shown in Fig. 8 (P1) substantially coincide with the upper and lower dimensions of the introduction opening of the ridge portion 600 shown in Fig. 8 (P3), but it is preferable to be larger than this.

左側***部601設置於連結柱530之左側面531與左側上部凸緣部511之內側面513之間。於連結柱530與左側上部凸緣部511之間，自連結柱530側依序配置有對向主面515、傾斜面611、及平坦面621。右側***部602設置於連結柱530之右側面532與右側上部凸緣部521之內側面523之間。於連結柱530與右側上部凸緣部521之間，自連結柱530側依序配置有對向主面515、傾斜面612、及平坦面622。 The left raised portion 601 is disposed between the left side surface 531 of the connecting post 530 and the inner side surface 513 of the left upper flange portion 511. Between the connecting post 530 and the left upper flange portion 511, a facing main surface 515, an inclined surface 611, and a flat surface 621 are sequentially disposed from the connecting post 530 side. The right side ridge portion 602 is provided between the right side surface 532 of the coupling post 530 and the inner side surface 523 of the right upper flange portion 521 . Between the connecting post 530 and the right upper flange portion 521, a facing main surface 515, an inclined surface 612, and a flat surface 622 are sequentially disposed from the connecting post 530 side.

左側上部凸緣511之內側面513及右側上部凸緣521之內側面523分別包含：一對後內側面13，其等自嚙合口側端部向導入口側延伸；及前內側面15，其自導入口側端部向嚙合口側延伸。後內側面13與前內側面15構成連續之內側面。左右之後內側面13係沿前後方向實質上平行地延伸之內側面。另一方面，左右之前內側面15係以兩者之間隔隨著自平行之後內側面13之端部延伸而擴大之態樣設置，換言之，左右之前內側面15至少包含設置為錐狀之第2前內側面12。進而，左右之前內側面15包含自第2前內側面12沿前後方向實質上平行地延伸之第1前內側面11。亦即，第2前內側面12設置於後內側面13與第1前內側面11之間。左右之第2前內側面12以相互之間隔逐漸變寬之方式設置為錐狀。 The inner side surface 513 of the left upper flange 511 and the inner side surface 523 of the right upper flange 521 respectively include a pair of rear inner side surfaces 13 extending from the side of the engagement opening side toward the inlet side, and a front inner side surface 15 The end portion from the inlet side extends toward the engagement opening side. The rear inner side surface 13 and the front inner side surface 15 constitute a continuous inner side surface. The left side inner side 13 is an inner side surface extending substantially in parallel in the front-rear direction. On the other hand, the left and right front inner side faces 15 are provided in such a manner that the interval between the two extends from the end portion of the inner side surface 13 after the parallel rotation, in other words, the left and right front inner side surfaces 15 include at least the second portion which is formed in a tapered shape. Front inner side 12. Further, the left and right front inner side surfaces 15 include a first front inner side surface 11 that extends substantially in parallel from the second front inner side surface 12 in the front-rear direction. That is, the second front inner side surface 12 is provided between the rear inner side surface 13 and the first front inner side surface 11. The left and right front inner side faces 12 are tapered in such a manner as to gradually widen each other.

於圖9所示之態樣下，較理想為於上翼板510之對向主面515設置有***部600。左側***部601之連結柱530側之邊界係藉由左側上部凸緣部511之後內側面13之延長而規定，且於其延長線或延長面上設置有該邊界。同樣地，右側***部602之連結柱530側之邊界係藉由右側上部凸緣部521之後內側面13之延長而規定，且於其延長線或延長面上設置有該邊界。藉此，可使拉鏈鏈齒於滑件主體540之鏈齒通路70內穩定地移動，從而滑件之操作性提高。又，容易避免於下述之模具之合模面上成形***部。藉此，可使拉鏈鏈齒於滑件主體540之鏈齒通路70內穩定地移動，從而滑件之操作性提高。又，容易避免於下述之模具之合模面上成形***部。 In the aspect shown in FIG. 9, it is preferable to provide the ridge portion 600 on the opposing main surface 515 of the upper blade 510. The boundary between the side of the connecting post 530 of the left raised portion 601 is defined by the extension of the inner side surface 13 after the left upper flange portion 511, and the boundary is provided on the extension or extension surface thereof. Similarly, the boundary of the right side ridge portion 602 on the side of the connecting post 530 is defined by the extension of the inner side surface 13 after the right upper flange portion 521, and the boundary is provided on the extension or extension surface thereof. Thereby, the fastener element can be stably moved in the element tooth passage 70 of the slider main body 540, and the operability of the slider can be improved. Further, it is easy to avoid forming the ridge portion on the mold clamping surface of the mold described below. Thereby, the fastener element can be stably moved in the element tooth passage 70 of the slider main body 540, and the operability of the slider can be improved. Further, it is easy to avoid forming the ridge portion on the mold clamping surface of the mold described below.

如根據圖9而可理解般，左側***部601至少部分地設置於與連結柱530之位置相比較位於相同側之後內側面13之朝連結柱530側之延長面PL13與前內側面15之間，更佳為設置於其整個區域。換言之，左側***部601係配置於左側上部凸緣部511之前內側面15所處之平面PL15、與和後內側面13所處之平面一致之延長面PL13之間。 As can be understood from FIG. 9, the left side ridge 601 is at least partially disposed between the extended surface PL13 and the front inner side 15 of the inner side surface 13 on the side of the connecting post 530 after being located on the same side as the position of the connecting post 530. It is better to set it in its entire area. In other words, the left side swelled portion 601 is disposed between the plane PL15 where the inner side surface 15 is located before the left upper flange portion 511 and the extension surface PL13 where the plane of the rear inner side surface 13 coincides.

並非必須限於此，於本例中，前內側面15包含：第1前內側面11，其與後內側面13平行地配向；及第2前內側面12，其傾斜地連接第1內側面11與後內側面13之間。因此，並非必須限於此，但較佳為，左側***部601配置於左側上部凸緣部511之第1前內側面11所處之平面PL11、與後內側面13之延長面PL13之間。平面PL11與延長面PL13相互平行，但並非必須限於此。雖並非必須限於此，但較佳為，左側***部601配置於左側上部凸緣部511之第2前內側面12所處之平面PL12、與後內側面13之延長面PL13之間。平面PL12係與平面PL11及延長面PL13傾斜地交叉之平面，且以面向連結柱530之方式設定。 In the present example, the front inner side surface 15 includes a first front inner side surface 11 that is aligned parallel to the rear inner side surface 13 and a second front inner side surface 12 that obliquely connects the first inner side surface 11 with Between the rear inner sides 13 . Therefore, the left side ridge portion 601 is preferably disposed between the plane PL11 where the first front inner side surface 11 of the left upper flange portion 511 is located and the extension surface PL13 of the rear inner side surface 13. The plane PL11 and the extension surface PL13 are parallel to each other, but are not necessarily limited thereto. Although it is not necessarily limited to this, it is preferable that the left side swelled portion 601 is disposed between the plane PL12 where the second front inner side surface 12 of the left upper flange portion 511 is located and the extension surface PL13 of the rear inner side surface 13. The plane PL12 is a plane that obliquely intersects the plane PL11 and the extension plane PL13, and is set so as to face the connection post 530.

關於右側***部602亦相同，右側***部602至少部分地設置於與連結柱530之位置相比較位於相同側之後內側面13之朝連結柱530側之延長面PL13'與前內側面15之間，更佳為設置於其整個區域。右側***部602係配置於右側上部凸緣部521之前內側面15所處之平面PL15'、與和後內側面13所處之平面一致之延長面PL13'之間。 The same applies to the right side ridge portion 602, and the right side ridge portion 602 is at least partially disposed between the extension surface PL13 ' on the side of the connection post 530 and the front inner side surface 15 of the inner side surface 13 on the same side as the position of the connection post 530. It is better to set it in its entire area. The right side raised portion 602 is disposed between the plane PL15 ' where the inner side surface 15 is located before the right upper flange portion 521 and the extended surface PL13 ' which coincides with the plane where the rear inner side surface 13 is located.

並非必須限於此，但較佳為，右側***部602配置於右側上部凸緣部521之第1前內側面11所處之平面PL11'與後內側面13之延長面PL13'之間。平面PL11'與延長面PL13'相互平行，但並非必須限於此。雖並非必須限於此，但較佳為，右側***部602配置於右側上部凸緣部521之第2前內側面12所處之平面PL12'與後內側面13之延長面PL13'之間。平面PL12'係與平面11'及延長面PL13'傾斜地交叉之平面，且以面向連結柱530之方式設定。再者，平面PL12與平面PL12'設定為間隔向前側變寬之錐狀。 It is not necessary to be limited thereto, but it is preferable that the right side raised portion 602 is disposed between the plane PL11 ' where the first front inner side surface 11 of the right upper flange portion 521 is located and the extended surface PL13 ' of the rear inner side surface 13. The plane PL11 ' and the extension surface PL13 ' are parallel to each other, but are not necessarily limited thereto. Although not limited thereto, it is preferable that the right side raised portion 602 is disposed between the plane PL12 ' where the second front inner side surface 12 of the right upper flange portion 521 is located and the extended surface PL13 ' of the rear inner side surface 13. The plane PL12 ' is arranged on the plane obliquely intersecting the plane 11 ' and the extension surface PL13 ' , and is set to face the coupling post 530. Further, the plane PL12 and the plane PL12' are set to have a tapered shape which is widened toward the front side.

於滿足上述一個以上或雖不會限定但較佳為滿足全部條件之情形時，可於更充分之範圍或程度限制拉鏈鏈齒400之移動空間，並且可避免於***部600延伸至嚙合口附近之情形時之不利。進而，亦有 如下述之模具裝置80之構成般可避免於合模面上成形***部600之情況。 When the above one or more of the above conditions are satisfied, but it is preferable to satisfy all the conditions, the moving space of the fastener element 400 can be restricted to a more sufficient extent or extent, and the ridge portion 600 can be prevented from extending to the vicinity of the meshing opening. The situation is unfavorable. Furthermore, there are The formation of the embossed portion 600 on the mold clamping surface can be avoided as in the configuration of the mold device 80 described below.

於如上所述考慮由樹脂冷卻所致之熱收縮之影響而較寬地設定上翼板510與下翼板520之間隔之情形時，成形後之滑件主體540之後端部之上翼板510與下翼板520之間隔係對應於拉鏈鏈齒400之上下高度而適當地設定。因此，若將上述***部600自滑件主體540之前端部側延伸至後端部側而設置，則無需因***部600而限制滑件主體540之嚙合口側之上下寬度，拉鏈鏈齒400相對於滑件主體540之位於後端部之***部600之接觸阻力增加，從而存在拉鏈90之操作性劣化之虞。 When the interval between the upper flap 510 and the lower flap 520 is broadly set in consideration of the influence of the heat shrinkage caused by the cooling of the resin as described above, the rear end portion of the slider main body 540 after the forming of the slider main body 540 is 510. The interval from the lower blade 520 is appropriately set corresponding to the upper and lower heights of the fastener element 400. Therefore, if the above-described raised portion 600 is provided from the front end side of the slider main body 540 to the rear end side, it is not necessary to restrict the upper and lower widths of the engaging opening side of the slider main body 540 by the raised portion 600, and the fastener element 400 The contact resistance with respect to the ridge portion 600 at the rear end portion of the slider main body 540 is increased, so that the operability of the zipper 90 is deteriorated.

本實施形態中，如上所述，左側***部601係以左側上部凸緣部511之後內側面13之延長面PL13為邊界設置於遠離連結柱530之區域而非設置於靠近連結柱530之區域。關於右側***部602與右側上部凸緣部521之關係亦為相同。因此，可使拉鏈鏈齒於鏈齒通路70內穩定地移動，從而滑件之操作性提高。 In the present embodiment, as described above, the left side swelled portion 601 is provided in a region away from the connection post 530 with the extension surface PL13 of the inner side surface 13 behind the left upper flange portion 511, and is not provided in a region close to the connection post 530. The relationship between the right side ridge portion 602 and the right side upper flange portion 521 is also the same. Therefore, the fastener element can be stably moved in the element tooth passage 70, so that the operability of the slider is improved.

如圖10所示，於拉鏈鏈齒400進入至滑件主體540內時，拉鏈鏈齒400進入至藉由***部600而使上下寬度變窄之導入口，從而確保拉鏈鏈齒400向滑件主體540內之順利的導入。如圖11所示，於拉鏈鏈齒400自滑件主體540內向外露出時，可將拉鏈鏈齒400自根據拉鏈鏈齒400之上下高度而設定之上下寬度之嚙合口順利地送出至外部。 As shown in FIG. 10, when the fastener element 400 enters into the slider body 540, the fastener element 400 enters the introduction port which narrows the upper and lower width by the ridge 600, thereby ensuring the slider element 400 to the slider. Smooth introduction within the main body 540. As shown in FIG. 11, when the fastener element 400 is exposed to the outside from the slider main body 540, the fastener element 400 can be smoothly sent out to the outside from the upper and lower widths of the fastener element 400.

參照圖12及圖13對由樹脂之冷卻所致之熱收縮之影響進行說明。圖12(a)係拉鏈滑件之設計模型，圖12(b)係使用樹脂材料成形後之拉鏈滑件之模型。如根據圖12而可明確瞭解般，於拉鏈滑件成形後，經由連結柱而連結之滑件主體之前端側之上翼板與下翼板之間隔並未較大地變動，但於易受樹脂材料之熱收縮之影響的無連結柱之滑件主體之後端部側，上翼板與下翼板之間隔不可忽視地減少。例如，圖13之實線表示設計模型，圖13之虛線表示成形後之樹脂製之拉鏈滑 件。 The influence of heat shrinkage by cooling of the resin will be described with reference to Figs. 12 and 13 . Fig. 12(a) shows a design model of the zipper slider, and Fig. 12(b) shows a model of the zipper slider formed by using a resin material. As can be clearly understood from FIG. 12, after the zipper slider is formed, the distance between the upper and lower flaps of the slider body connected to the front end side of the slider body is not greatly changed, but is susceptible to resin. The rear end side of the slider body of the unjoined column, which is affected by the heat shrinkage of the material, the interval between the upper and lower flaps is not negligibly reduced. For example, the solid line in Fig. 13 indicates the design model, and the broken line in Fig. 13 indicates the zipper slide made of resin after molding. Pieces.

如上所述於本實施形態中，於滑件主體540之前端側，於連結柱530之左右設置有***部600。即便於考慮樹脂之熱收縮之影響而較寬地設定上翼板510與下翼板520之間隔之情形時，亦可充分地限制拉鏈鏈齒400於滑件主體540之前端部之滑件主體540內之移位。再者，亦考慮減少上翼板或下翼板之板厚來應對，或於設計模型中預先將嚙合口側之上下翼板間之上下尺寸設定得寬於導入口側之上下翼板間之上下尺寸，但自抽拉模具芯之觀點而言存在難以抽拉之虞。 As described above, in the present embodiment, the swelled portion 600 is provided on the front end side of the slider main body 540 on the right and left sides of the connecting post 530. That is, in the case where the interval between the upper blade 510 and the lower blade 520 is set wider in consideration of the influence of the heat shrinkage of the resin, the slider body of the front end portion of the slider element 400 at the front end of the slider body 540 can be sufficiently restricted. Shift within 540. Furthermore, it is also considered to reduce the thickness of the upper or lower wing to deal with, or to pre-set the upper and lower dimensions between the upper and lower wings of the meshing opening side in the design model to be wider than the upper wing of the inlet side. The upper and lower dimensions, but from the point of view of drawing the mold core, it is difficult to pull.

Fig. 15 is a cross-sectional view showing the mold apparatus of the plane Q1 to Q3 of Fig. 14. As shown in FIG. 15, the mold apparatus 80 includes a first mold 810 that forms a coupling post 530 from the inlet side of the slider main body 540, and a second die 820 that forms a coupling post 530 from the engagement opening side of the slider main body 540. a third mold 830 that forms an upper surface of the slider body 540, and a fourth mold 840 that shapes the upper surface of the slider body 540. The mold dividing line PL10 shown in FIG. 14 is a mold dividing line between the first die 810 and the second die 820.

如圖15所示，第1模具810包含用以成形上翼板510之對向主面515之模具上表面811、及用以成形下翼板520之對向主面525之模具下表面812。第2模具820亦同樣地包含用以成形上翼板510之對向主面515之模具上表面821、及用以成形下翼板520之對向主面525之模具下表面822。 As shown in FIG. 15, the first mold 810 includes a mold upper surface 811 for forming the opposing main surface 515 of the upper blade 510, and a mold lower surface 812 for forming the opposing main surface 525 of the lower blade 520. The second mold 820 similarly includes a mold upper surface 821 for forming the opposing main surface 515 of the upper blade 510, and a mold lower surface 822 for forming the opposing main surface 525 of the lower blade 520.

模具上表面811相當於申請時由請求項特定出之用語之第1成形面(811)。模具上表面821相當於申請時由請求項特定出之用語之第4成形面(821)。 The upper mold surface 811 corresponds to the first molding surface (811) of the term specified by the request item at the time of application. The upper mold surface 821 corresponds to the fourth molding surface (821) of the term specified by the request item at the time of application.

於第1模具810設置有用以成形上述左右***部600之左右一對凹部30，凹部30包含用以成形上述***部600之傾斜面610之模具傾斜面31、及用以成形上述***部600之平坦面620之模具平坦面32。凹部30 並未設置於第1模具810與第2模具820之模具分割線PL10上，而是遠離模具分割線PL10而設置，因此，於模具分割線PL10與凹部30之間設置有與第2模具820之模具上表面821成為同一平面之第1模具810之模具上表面811。藉此，與凹部30鄰接於模具分割線PL10之情形相比較，可減少毛邊之產生，又可準備銳角部分減少之耐久性較高之模具。藉由模具之耐久性之提高而可謀求拉鏈滑件之製造成本之降低。 The first mold 810 is provided with a pair of left and right recesses 30 for forming the right and left raised portions 600. The recess 30 includes a mold inclined surface 31 for forming the inclined surface 610 of the raised portion 600, and a shape for forming the raised portion 600. The mold flat surface 32 of the flat surface 620. Concave 30 Since it is not provided on the mold dividing line PL10 of the first die 810 and the second die 820, but is provided away from the die dividing line PL10, the second die 820 is provided between the die dividing line PL10 and the recess 30. The upper mold surface 821 is a mold upper surface 811 of the first mold 810 having the same plane. Thereby, compared with the case where the recessed part 30 is adjacent to the mold division line PL10, the generation of a burr can be reduced, and the mold with a high durability with the acute-angle part reduced can be prepared. By reducing the durability of the mold, it is possible to reduce the manufacturing cost of the zipper slider.

As can be understood from Fig. 15, the recess 32 on the left side is disposed on the plane PL813 where the molding surface 813 of the first die 810 of the first front inner side surface 11 of the left upper flange portion 511 is formed, and the left side is formed. The upper flange portion 511 is between the plane PL823 where the molding surface 823 of the second mold 820 of the inner side surface 13 is located. The recessed portion 30 on the right side is also the same, and is disposed on a plane PL814 where the molding surface 814 of the first die 810 of the first front inner side surface 11 of the right upper flange portion 521 is formed, and the right upper flange portion 521 is formed.

如圖15所示，相對於合模後之模具裝置80，將熔融樹脂經由未圖示之流槽而供給至模具裝置80內之成形模穴，藉由模具裝置80之冷卻而降溫並固化後自模具裝置80取出，藉此成形拉鏈滑件500。於對模具裝置80供給熔融樹脂之後的熔融樹脂降溫之初始階段，滑件之形狀成為與圖12(a)所示之設計模型相同之狀態。於該狀態下，設定藉由滑件主體之導入口側之***部而變窄之上下翼板間之尺寸、亦即上翼板之對向主面之***部與下翼板之對向主面之間的間隔小於滑件主體之嚙合口側之上下翼板間之尺寸、亦即上翼板之對向主面與下翼板之對向主面之間的間隔的尺寸差△h。又，該狀態下，滑件主體之導入口側之不存在***部600之對向主面的上下尺寸，為與滑件主體之嚙合口側之上下翼板間的上下尺寸相同之程度。 As shown in FIG. 15, the molten resin is supplied to the molding cavity in the mold device 80 via the launder (not shown) after the mold clamping device 80 is closed, and is cooled and solidified by the cooling of the mold device 80. The zipper slider 500 is formed by taking out from the mold device 80. In the initial stage of cooling the molten resin after the molten resin is supplied to the mold device 80, the shape of the slider is in the same state as the design model shown in Fig. 12(a). In this state, the size of the upper and lower flaps, that is, the ridge between the opposing main faces of the upper flap and the lower flap, is narrowed by the bulging portion on the inlet side of the slider main body. The interval between the faces is smaller than the dimension between the lower flaps on the engaging opening side of the slider main body, that is, the difference in the interval between the opposing main faces of the upper flap and the opposing main faces of the lower flap. Further, in this state, the vertical dimension of the opposing main surface of the swelled portion 600 on the inlet side of the slider main body is the same as the upper and lower dimensions between the upper and lower flaps on the engagement opening side of the slider main body.

該尺寸差△h係例如於自模具內或模具上卸下之後，伴隨熔融樹脂之進一步降溫，藉由樹脂材料之熱收縮而使滑件主體之嚙合口側之上下翼板間的上下尺寸變得窄於導入口側之上下翼板間的上下尺寸，因此其結果為，上述尺寸差△h之值變小。 The dimensional difference Δh is, for example, after being removed from the mold or the mold, and with the further cooling of the molten resin, the upper and lower dimensions between the upper and lower wings of the slider body are changed by thermal contraction of the resin material. It is narrower than the upper and lower dimensions between the lower and upper wings on the inlet side, and as a result, the value of the above-described dimensional difference Δh becomes small.

又，本實施形態中，以使上下凸緣間之間隙不會因受熱收縮影響而變得過窄之方式，如表示設計模型之狀態(或對模具裝置80供給熔融樹脂之後的熔融樹脂降溫之初始階段之狀態)之圖12(a)所示，將嚙合口側形成得寬於導入口側。嚙合口側之上下凸緣間之間隔係藉由自各凸緣之中間位置向嚙合口側端部暫時緩慢地減少之傾斜面而構成。該傾斜面設置於上下凸緣部之至少一凸緣部。藉此，即便如圖12(b)般藉由樹脂材料之熱收縮而使滑件主體之嚙合口側之上下翼板間的上下尺寸變得窄於導入口側之上下翼板間的上下尺寸，亦可確保上下凸緣間之拉鏈鏈布插通路。 Further, in the present embodiment, the gap between the upper and lower flanges is not excessively narrowed by the heat shrinkage, and the state of the design model is displayed (or the molten resin after the molten resin is supplied to the mold device 80 is cooled). In the state of the initial stage, as shown in Fig. 12 (a), the engagement opening side is formed wider than the introduction port side. The interval between the upper and lower flanges on the meshing port side is constituted by an inclined surface which is temporarily and gradually reduced from the intermediate position of each of the flanges toward the meshing port side end portion. The inclined surface is provided on at least one flange portion of the upper and lower flange portions. Thereby, even if the resin material is thermally contracted as shown in FIG. 12(b), the upper and lower dimensions between the upper and lower flaps on the meshing opening side of the slider main body are narrower than the upper and lower dimensions between the lower flaps on the inlet side. It can also ensure the zipper chain insertion path between the upper and lower flanges.

亦即，本說明書中揭示之拉鏈滑件係基於假定有樹脂材料之熱收縮之設計模型而製作，其製造方法包含：(i)準備複數個模具之步驟，該等模具係用以成形拉鏈滑件(500)，該拉鏈滑件(500)包含滑件主體(540)，該滑件主體(540)係將上翼板(510)與下翼板(520)經由連結柱(530)而連結，且於上述上翼板(510)與上述下翼板(520)之間形成有插通拉鏈鏈齒(400)之鏈齒通路(70)，自上述滑件主體(540)之嚙合口側向導入口側延伸之一對凸緣部(550)設置於上述上翼板(510)及上述下翼板(520)之至少一者；(ii)步驟，係使上述複數個模具合模之步驟，藉由合模之上述複數個模具而形成之空間形狀為於上述上翼板(510)與上述下翼板(520)之各對向主面之至少一者形成有***部(600)，且該***部(600)以配置於上述滑件主體(540)之導入口側之方式劃定；(iii)步驟，於上述複數個模具合模之狀態下，將熔融樹脂供給至藉由上述複數個模具而形成之空間；(iv)步驟，使上述所供給之熔融樹脂降溫而將熔融樹脂固化；及(v)步驟，自上述複數個模具取出上述已固化之熔融樹脂；且於上述降溫之初始階段，藉由上述***部(600)及與上述***部(600)對向之上述對向主面而設定上述滑件主體(540)之導入口之第1上下尺寸，藉由不存在上述***部(600)而設定較上述第1上下尺寸大之上述滑件主體(540)之嚙合口之第2上下尺寸，且設定上述第1上下尺寸與上述第2上下尺寸之差分之尺寸差△h，於進一步降溫後，上述滑件主體(540)之上述嚙合口之上述第2上下尺寸減少，藉此，進一步降溫後之上述尺寸差△h變得小於降溫初始階段之上述尺寸差△h。 That is, the zipper slider disclosed in the present specification is manufactured based on a design model assuming thermal contraction of a resin material, and the manufacturing method thereof includes: (i) a step of preparing a plurality of dies for forming a zipper slide A piece (500), the zipper slider (500) includes a slider body (540) that connects the upper blade (510) and the lower blade (520) via a connecting post (530) And a sprocket passage (70) through which the fastener element (400) is inserted is formed between the upper wing plate (510) and the lower wing plate (520), from the engagement side of the slider body (540) One pair of flange portions (550) extending from the inlet side of the guide are disposed on at least one of the upper wing plate (510) and the lower wing plate (520); (ii) the step of clamping the plurality of molds a step of forming a ridge formed by at least one of the opposing main faces of the upper blade (510) and the lower blade (520) by a plurality of molds that are clamped by the mold. And the ridge portion (600) is defined so as to be disposed on the introduction port side of the slider body (540); (iii) the step is to melt the mold in the state in which the plurality of molds are clamped The resin is supplied to a space formed by the plurality of molds; (iv) a step of cooling the molten resin supplied to cure the molten resin; and (v) a step of removing the solidified melt from the plurality of molds a resin; and in the initial stage of the temperature lowering, the first upper and lower sides of the inlet of the slider body (540) are set by the raised portion (600) and the opposing main surface facing the raised portion (600) The second upper and lower dimensions of the engagement opening of the slider body (540) larger than the first upper and lower dimensions are set by the absence of the raised portion (600), and the first vertical dimension and the second upper and lower dimensions are set. The difference in size between the dimensions is Δh. After further cooling, the second upper and lower dimensions of the meshing opening of the slider body (540) are reduced, whereby the dimension difference Δh after further cooling becomes smaller than the initial temperature drop. The above dimensional difference Δh of the stage.

於上述製造方法特定出之降溫前後之尺寸差△h之減少可根據本案說明書整體之揭示，尤其藉由參照圖12及圖13而可明確瞭解，故而 省略多餘之說明。藉由使用利用此種模具裝置或製法製造之拉鏈用滑件，即便為由易受熱收縮之影響之樹脂材料而製造之滑件、尤其尺寸較大之滑件、或拉鏈鏈齒易旋轉之如專利文獻1或專利文獻2中記載之拉鏈鏈齒，亦可於鏈齒通路內穩定地導引拉鏈鏈齒，因此可使拉鏈滑件之操作性提高。 The reduction of the dimensional difference Δh before and after the temperature reduction specified by the above manufacturing method can be clearly disclosed according to the entire description of the present specification, and can be clearly understood by referring to FIG. 12 and FIG. Omit redundant descriptions. By using a slider for a slide fastener manufactured by such a mold device or a method, even a slider manufactured by a resin material which is susceptible to heat shrinkage, particularly a slider having a large size, or a fastener element is easily rotated. The fastener element described in Patent Document 1 or Patent Document 2 can stably guide the fastener element in the element tooth passage, so that the operability of the slide fastener can be improved.
