Description

200306163 ⑴ 玖、發明說明【發明所屬之技術領域】本發明是關於：在由合成樹脂薄膜等所構成之袋本體的開口附近，具備可對袋進行開閉、密封之咬合式夾鏈（接合器）的具有夾鏈的密封袋。特別是指：在夾鏈的帶（tape)端緣部設有朝袋本體的內側面及外側面突出之一體成型的突起部，並藉由於不會由袋本體開口露出的內側處，將該突起部配設成不會融著於袋側的構造來避免夾鏈及袋整體的大型化，避免製作袋子過程中產生熔解、扁平化等問題，能提升袋子的開封性且適用於收納樂品、食品及雑貨等小型密封袋之具有夾鏈的密封袋。【先前技術】一般具有夾鏈的密封袋，是在由合成樹脂等製成之袋本體的開口部處，黏著凹凸咬合式的樹脂製夾鏈。由於這種具有夾鏈的密封袋能以低廉的成本大量生產袋本體，除了質量輕且具有良好的可撓性及耐水性之外，更能自由開閉其咬合式的夾鏈，並且可藉由封閉夾鏈來輕易地使袋內形成密封，因此，普遍被作爲收納藥品、食品及雜貨等的容器、袋子使用。而該種樹脂製密封袋所具備的夾鏈，由於是在樹脂製的帶（tape)表面形成一對可自由咬合鬆脫的凹凸咬合具，故帶（tape)被熱融著於袋本體的開口附近，利用使咬合具之凹凸部形成咬合及脫離，可開閉袋子的開 -6 - (2) (2)200306163 口，當咬合具形成咬合狀態時袋子的內部便形成密封。上述密封袋所具備之夾鏈的開啓與閉合，當於袋子封閉時，令形成相對且分離狀之凹部與凸部的局部相互相嵌合並以手指挾持，再由手指按壓該挾持部分形成咬合後，200306163 玖发明, description of the invention [Technical field to which the invention belongs] The present invention relates to a bite-type chain (joint) provided in the vicinity of an opening of a bag body made of a synthetic resin film or the like that can open and close the bag Sealed bag with zipper. In particular, the tape edge of the chain is provided with a protrusion formed on the inner side and the outer side of the bag body, and the inner side is not exposed through the opening of the bag body. The protrusions are arranged so as not to melt on the side of the bag to avoid the large size of the chain and the entire bag, to avoid problems such as melting and flattening during the process of making the bag. It can improve the openability of the bag and is suitable for storing music. , Sealed bags with chain, small food sealed bags, etc. [Prior art] Generally, a sealed bag with a zipper is a resin zipper of a concave-convex bite type that is adhered to an opening portion of a bag body made of synthetic resin or the like. Since this sealed bag with a chain can mass-produce the bag body at a low cost, in addition to being lightweight and having good flexibility and water resistance, it can freely open and close its snap-on chain, and can be used by The clip chain is closed to easily seal the inside of the bag. Therefore, it is widely used as a container or bag for storing medicines, foods, and groceries. However, since the clip chain included in the resin-sealed bag is formed on the surface of the resin tape, a pair of concave-convex occlusal devices capable of freely engaging and releasing, the tape is fused to the bag body. In the vicinity of the opening, the opening and closing of the bag can be opened and closed by engaging and disengaging the concave-convex portion of the bite. When the bite is in the bite state, the inside of the bag is sealed. The opening and closing of the clip chain provided in the above-mentioned sealed bag, when the bag is closed, the concave and convex portions forming opposite and separated shapes are fitted to each other and held by fingers, and then the fingers are pressed to form a bite ,

藉由手指沿著開口部滑動，可令凹凸部依次咬合進而關閉整個夾鏈。當欲開啓凹凸部成咬合狀的夾鏈時，是以手指將袋本體的開口緣部朝兩側拉取，以便解除凹部與凸部的局部咬合，再由分離的咬合部起依次分離後解除夾鏈整體的咬合，這樣一來便能開啓袋子。 H 然而，由於如上所述之具有夾鏈的密封袋，其袋本體是由聚丙烯等薄膜所構成，當開啓夾鏈時供使手指挾持的帶（tape)子開口邊緣容易打滑，特別是指尖潮濕或力量較小的人開啓時，由於手指的滑動而不易打開夾鏈。通常，這類密封袋爲了能確實地使袋子內部形成密封，其構成夾鏈的一對凹凸咬合部會形成一定強度的咬合，因而無法輕易地打開。因此，導致袋子把持部容易打滑之傳統密封袋的開啓困難，特別是作爲老人或小孩之醫藥袋 φ 、或作爲家庭中主婦用來收納食品或雜貨的收納袋時，將突顯其不易開啓及使用便利性上的問題。因此，到目前爲止，爲了防止開啓上述樹脂製密封袋時手指打滑並減輕夾鏈開啓的困難度，乃提出一種於袋子開口部附近設置突條供手指拉取之具有手指防滑構造的密封袋。第Η、1 2圖中，便顯示至今具有手指防滑構造之習知 -7- (3) (3)200306163 密封袋的剖面圖，第1 1圖是密封袋整體的側面剖面圖，第 1 2圖是袋子開口部附近重要部位的側面剖面圖。第1 1圖所顯示的密封袋，是由日本實開平3 - 1 93 1 3號公報所揭示，其中是使構成一對凹凸咬合具1 1 2 ( 1 1 2 a、 1 1 2b )的夾鏈1 1 1 (該公報中稱爲軌道狀咬合器）在樹脂製袋本體1 〇 1開口緣部外側形成連續性貼合，並使做爲該夾鏈11 1外側緣部的拉取部1 1 3 a、1 1 3 b朝外側突出形成彎折後，於該拉取部1 1 3 a、1 1 3 b的端緣形成剖面呈三角形的膨大部1 14a、1 14b作爲手指防滑手段。根據該密封袋得結構，藉由手指拉取位於夾鏈1 1 1外側末端部的膨大部 1 14a、1 14b，可避免手指於開啓袋子時的滑動，進而開啓夾鏈1 1 1。第12圖所顯示的密封袋，是由日本實開平5 - 7 63 09號公報所揭示，其作法與第1 1圖所示的密封袋相同，是使構成一對凹凸咬合具212 (212a、212b)的夾鏈211 (該公報中稱爲軌道狀咬合器）在樹脂製袋本體2 0 1開口緣部外側形成連續性貼合，形成做爲該夾鏈2 1 1外側緣部的拉取部 2 1 3 a、2 1 3 b，並於該拉取部2 1 3 a、2 1 3 b的表面上形成複數條突條2 1 4、2 1 4 作爲手指防滑手段。根據該密封袋的結構，由於位於夾鏈2 1 1表面的突條2 1 4、2 1 4 間形成一定的間距，可供指腹嵌入該複數突條2 1 4、2 1 4 之間’藉此可避免手指於開啓袋子時產生的滑動。但是，在至今所提出之具備手指防滑結構的密封袋中，無論是任何一種都如第1 1、1 2圖所示地，夾鏈的結構都 -8- (4) (4)200306163 是由袋本體開口部起連續融著於外側，且由於形成iu取部的夾鏈外緣朝更外側的方向突出，因而導致含有夾鏈的帶 (tape)整體過於大型化。雖然這類因夾鏈導致密封袋的大型化，不會對用來收納寢具、衣物等大型物品的大型密封袋造成影響，但對於用來收納藥品、食品等輕薄型密封袋而言’其所造成影響則不容小窺。此外，上述夾鏈連續形成於袋子開口外側的結構中，由於夾鏈本身形成開口部，且夾鏈的周圍並未覆蓋有其他的東西，因此打開夾鏈時容易導致內容物溢出、或異物的侵入，特別是作爲收納細小物品、液體等家庭或醫療用小型密封袋使用時，此一現象更爲明顯。再者，在袋子開口側末端形成上述夾鏈的密封袋中，會產生袋子開口部份無法密封（頂端密封）的問題。舉例來說，當這類密封袋作爲物流（運輸）用的袋子使用時，袋內有完全密封的必要，故必須將包含夾鏈袋側開口部的袋子4邊徹底密封。但在袋子開口部外側配設夾鏈且形成止滑用拉取部的密封袋，由於其袋子開口並無法密封，因此並不適合作爲物流所使用的密封袋。而，如第1 1圖所示的密封袋，在夾鏈最末端具備突條 (膨大部）的止滑結構中，由於膨大部到外側之間並不存在連續的部分，以致手指的力量僅能集中於膨大部，由於膨大部強烈地壓迫指尖，將如日本實開平5 - 7 6 3 0 9號公報所描述地，使指尖感到痛楚及麻痺的問題。另外，如第i 2圖所示的密封袋，在拉取部兩面分別形 -9- (5) (5)200306163 成有複數條突條的結構中’由於形成於不同位置之複數突條將導致手指的力量分散，反而產生手指難以出力的問題〇至此，於是發展出一種使夾鏈整體小型化’且配設融著於袋本體的內面並使突條等止滑手段突出於該袋子內面的結構，作爲避免發生上述將夾鏈連續融著於袋本體外側之傳統密封袋問題的手段。但是，僅是單存地將夾鏈配設於袋本體的內面，難以限制突條等只朝袋子的內面側突出，故無法充分地作爲手指防滑手段。此外，當將夾鏈融著於袋本體之際，配設於袋子內面的突條等也將隨著夾鏈熔解而導致扁平化，這樣一來恐有降低手指防滑手段功能之虞。於是，爲了防止上述突條因熔解而形成扁平化的情形產生，則又發展出即使 I谷解也保持一疋長度地’預先延長突條等長度的做法，但是在這種單存地延長突條的結構中，由於製作袋子的過程中突條容易傾倒故有其製作上的困難，更因爲突條朝袋子內側突出的長度過長，使得手指不易伸入袋子的開口內，反而降低袋子的開閉性。本案便是因應上述傳統技術上問題所硏發出的發明，本案的目的是提供一種：在夾鏈的帶（tape)端緣部一體成型地設有朝袋本體內、外側面突出的突起部，並藉由採用不會融著於袋側的配設方式，將該突起部配設於不會從袋本體開口露出的內側’以防止夾鏈及袋子整體的大型化，並避免製作過程中因熔解所導致的扁平化，可確實地提升 -10- (6) 200306163 袋子開封性，特別適合用於收納藥品、食品及雜貨等密封袋之具有夾鏈的密封袋。【發明內容】爲了達成上述的目的，本發明之具有夾鏈的密封爲具備：其中一形成開口的袋本體；和具有貼著於該體開口附近且沿著該袋本體開口形成對向狀的一 (t a p e)、及形成於前述一對帶（t a p e)的對向面上，可沿述袋本體開口自由緊閉/分離地形成咬合，進而可自閉地密封該袋本體之一對凹凸咬合具的夾鏈之具有夾密封袋，其特徵爲：前述一對帶（tape)並不會在前述體開口側端緣部形成突條，而是具備一體成型地朝袋內、外側突出的突起部，該突起部可藉由使前述一 (tape)貼合於前述袋本體內面的前述開口內側，形成較該袋本體開口緣部更內側的結構。具有上述結構之本案具有夾鏈的密封袋，沿著用閉密封袋本體的夾鏈端緣部，具備開閉袋子時作爲手滑手段的突起部，該突起部與夾鏈同樣被配設在較該體開口部更內側的位置。藉由將夾鏈與突起部配設在體的內側，可防止夾鏈與防滑構造如傳統密封袋一般側大量突出，進而達成夾鏈與袋子整體的小型化。而由於含有上述突起部的夾鏈形成收納於袋本體構造，可以使袋本體的開口緣部較夾鏈更朝外側突出可由袋本體來覆蓋住具有夾鏈的全體開口部，因此於小型袋是袋本對帶著前由開鏈的袋本本體對帶位於來開指防袋本袋本朝外內的，故開閉 -11 - (7) (7)200306163 密封袋之際可避免內容物溢出或異物入侵的情形產生。而形成密封袋之手指防滑手段的本案突起部，由於夾鏈形成貼合於袋本體內面的狀態，故能於一體成型且平均地朝袋本體的內側面及外側面突出後，形成剖面呈圓形等狀的突條，而該突條是位在不會由袋本體露出的袋子內側。藉由形成上述的結構，由於突起部一體成型地突出於袋子的內、外側面，當開閉袋子時，可由袋子的內外側面以 2隻手指確實地挾持單一位置。此外，由於突起部位於袋本體的內側，使得袋子開口緣部朝由手指所挾持之突起部的外側（手指的與手掌連接的部位）延伸，而該延伸的緣部也能與突起部同時被手指所挾持。根據以上的說明，由於本發明的密封袋可挾持突出於袋子內外側之突出部的同一部位，因此可以不分散力量地確實固定突起部，更由於能連帶地挾持由突起部延伸出的袋緣部’可以固定袋子的整個開口緣部，而不是僅將力量集中於突起部。藉此，能以簡易且平順的方式確實地開啓密封袋，故不會令手指打滑，也不會產生如習知密封袋導致指尖痛楚或麻痺的問題。再者，相較於傳統密封袋中分別由袋子的內側面及外側面突出的突條，由於本案可由袋子內外同時挾持單一位置，故可縮小朝袋子內、外側面突出的寬度，因此並不會產生因製作袋子的過程中突條容易傾倒導致製作不易、及突條朝袋子內側突出的長度過長導致手指不易伸入袋子開口內的問題。而當利用熱融著使前述一對帶（tape)貼合於前述袋本 -12- (8) (8)200306163 體的內面時’本案的密封袋中具備該一對帶（tape)的前述突起部則不會熱融著於前述袋本體內面。由於這樣的結構，當緣部備有突起部的夾鏈熱融著於袋本體時，只有突起部以外的部分會融著於袋側’突起部則不會融著於袋側。雖然，一般合成樹脂製密封袋的夾鏈是利用熱融著的方式一體成型地貼合於袋本體，但倘若直接熱融著具有突起部的夾鏈整體，將會因熱量使突起部熔解產生扁平化，恐有導致降低手指防滑效果之虞。而本發明中，藉由使突起部以外的部分融著於袋側，形成突起部不會融著於袋側的構成方式’可以避免突起部被熔解所產生的扁平化，使突起部充分發揮本案中手指防滑手段的功效。此外，在本發明的密封袋中，前述突起部是形成面對前述袋本體的深度方向，並配設在相同位置的結構，但也能形成配置於不同位置的結構。藉由這種將位於袋本體內面呈對向狀的突起部，在袋本體的深度方向上配設於不同位置的構成方式，當夾鏈形成咬合狀態，也就是指封閉密封袋的狀態下，形成對向狀的突起部之間並不會產生干涉。在突起部不會產生上述干涉的本發明中，可在夾鏈咬合時帶（tape)的對向面之間距離的範圍內，將各突起部的外形設成適當的大小，由於突起部可形成手指容易施力且容易插入的尺寸與外形，故能更進一步提升密封袋的易開閉性。而本發明之突起部的尺寸，當突起部被配設在袋本體深度方向的相同位置時，前述袋本體的內面側與外面側於 -13- 200306163 Ο) 突出方向上的最大寬度爲0 3 mm以上〜帶（tape)之對向面間以下的距離。藉由形成上述的結構，可在不形成干涉的範圍內’將位於帶（tape)之相對面間呈咬合狀的突起部設成最大。最好是將袋本體的內面側與外面側於突出方向上的最大寬度爲0 5腿以上〜帶（tape)之對向面間的1/2距離以下 ’這樣將更容易抓取，並在凹、凸突起之間設置間隙使手指更容易插入。在藥品及食物所採用的小型密封袋中，雖然當帶 (tape)的厚度約爲0 15〜0 16mm時，呈咬合狀之帶（tape)的對向面間的距離通常約爲1 5mm，但因爲突出於該帶（tape) 之對向面並形成對向狀的突起部之間，產生帶（tape)對向面之間的干涉，使得開啓袋子時手指不易插入，將有損於袋子的開啓便利性。另外，當爲了提升手指插入性而縮小該突起部時，一旦突起部的突出寬度低於0 3 mm以下，因爲突起部太小將降低手指的牽引性，導致手指防滑手段的效能不彰。因此在本發明中，譬如帶（tape )的厚度約爲 0 15〜0 16匪左右，突起部朝袋本體內外面突出最大寬度則形成0 3讓以上〜帶（tape )之對向面間距離以下的尺寸，其中又以最大寬度形成〇 5 mm以上〜帶（tape)之對向面間距離的1/2 (約〇 7mm )以下最合適，即使是突起部在袋本體內面之相同位置形成對向配置的狀態下，只要確保手指的牽引性的同時，將突出於帶（tape)對向面間之突出部的突出總寬度設成低於帶（tape)的對向面間距（約1 5腿），便是無損於手指插入性的結構。藉此，本發明能提供一種兼 -14- (10) (10)200306163 顧良好手指牽引性及易插入性，且具有良好開啓性的密封袋。另外，當突起部被配置在袋本體深度方向上的不同位置時突起部的尺寸，形成朝前述袋本體內外側面突出的最大寬度爲〇 3匪〜2 〇 mm，其中最大寬度又以〇 5腦以上最合適。在前述的狀態下’突出於袋本體內、外面側的最大寬度爲〇 3mm以上〜帶（tape)對向面間距以下，其中最大寬度又以〇 5 mm以上最佳。藉由形成以上的結構，當夾鏈咬合之際突起部在不同的位置被配置成對向狀時’能在帶 (tape)對向面間距的最大範圍內，形成更大的突起部。如上所述地，當小型密封袋的帶（tape)厚度約爲0.15 imn〜0 16醒時，夾鏈咬合之際帶（tape)對向面間距約爲1 5 U1II1左右。另外，突起部的突出寬度一旦不滿0 3腿時，將降低手指的牽引性導致手指防滑的效果不彰。因此在本發明中，當突起部在袋本體內面的不同位置爲配設成對向狀時，譬如帶（tape)的厚度約爲〇 15〜〇 16mm左右之際，突起部朝袋本體內外面突出最大寬度則形成〇 3隱〜2 〇腿的尺寸’其中又以最大寬度形成〇 5醒以上〜帶（tape)之對向面間距離（約1 5腿）以下最合適。藉此，帶（tape)的各突起部’可在相互不產生干涉的狀態下，於帶（tape)之對向面間距的範圍內形成最大値，可更進一步提升手指防滑性，並提高密封袋的開啓便利性。而’突起部可形成剖面呈圓形的凸肋，或者剖面呈角形的凸肋。這樣一來’本案的突起部，僅限於可一體成型 -15- (11) (11)200306163 地朝袋本體內面側及外面側突出的凸肋，對其剖面形狀則無特別的限制，舉例來說，可爲剖面成圓形的凸肋，或者剖面呈四角形或菱形等角形的凸肋。換言之，本案的突起部’可因應密封袋及夾鏈的大小、和夾鏈的咬合力，選擇性地設成最適合本案密封袋的剖面形狀，藉由具備這樣的突起部’可構成具有絕佳泛用性及擴張性之具有夾鏈的密封袋。【實施方式】接下來，參考圖面對本案具有夾鏈的密封袋之最佳實施形成進行說明。〔第一實施形態〕首先’參考第1圖〜第9圖來說明本案具夾鏈的密封袋之第一實施形態。第1圖，是簡化顯示本發明中第1實施形態的具有夾鏈之密封袋的袋整體側面剖面圖。第2圖，是簡化顯示本發明中第1實施形態之具有夾鏈的密封袋之夾鏈部分的側面剖面圖，其中（a

)爲傳統的密封袋。如上述各圖所示，本實施形態之具有夾鏈的密封袋是由：於其中一側具有開口部1 a之袋狀的袋本體丨；及具備貼合於該袋本體1開口部1 a附近之凹凸咬合式夾鏈1 0的密封袋所構成。而5在作爲貼合於袋本體1內面的夾鍵10之母材的一* 對帶1 1的緣部，具備突出於袋子內外面，作爲開啓袋子時之手指防滑手段的一對突起部20 ( 20a、20b )。袋本體1，爲其中一側形成開口的袋狀樹脂製的袋體。通常該袋本體1，是由2張平面呈矩形的樹脂製薄膜（雌側薄膜2及雄側薄膜3 )重疊、或彎折1張樹脂製薄膜後重疊後，如第3圖所示地，藉由利用熱融著等手段使形成開口部1 a側之外的其他3側（或2側）貼合（請參考第3圖中的貼著部5 )，製作成袋狀。在此，構成袋本體1的樹脂製薄膜，通常是採用由二軸延伸的聚丙烯薄膜與模鑄聚丙烯薄膜所疊層而成的薄膜，並根據作爲收納對象之內容物的各種尺寸加以裁剪後製作成袋子。夾鏈1 〇用來自由開閉地密封袋本體1其中一側之開口部1 a的開閉手段，如第1圖所示，其具備配設於袋本體1 開口側1 a附近的一對帶1 1 ( 1 1 a、1 1 b )、及形成於該帶 11表面的一對凹凸咬合具12(12a、12b)。一對的帶1 1，係指沿著開口部1 a形成對向配置地貼著於袋本體1內面的帶狀構件（請參考第3圖），如第1圖所示地，是由作爲一對咬合具1 2a、1 2b之母材的雌側帶 -17- (13) (13)200306163 1 1 a與雄側帶1 1 b所構成。通常該一對帶1 1 a、1 1 b是由聚丙烯等合成樹脂所形成，並藉由熱融著貼著於袋本體1的內面。而在本實施形態中，該對帶1 1 a、1 1 b則如第3圖所示地，貼著於由袋本體1內面開口部1 a進入袋內側的位置，如稍後所述地，使沿著帶1 1端員所形成的突起部20不會從袋本體1的開口部la處露出。一對的咬合具1 2，是在呈對向狀之一對帶1 1 a、1 1 b 的各表面上形成一條之雌雄一對的咬合手段，如第1圖所示地，是由形成雌側帶1 1 a的雌側咬合部1 2 a與形成雄側帶1 1 b的雄側咬合部1 2b所構成，兩個咬合部1 2a、1 2b，是在袋本體1內側面對應的相同位置上形成對向狀的配置〇如第2圖所示地，藉由使雌側咬合部1 2 a與雄側咬合部1 2 b自由嚙合鬆脫地形成咬合，可以自由開閉地密封袋本體1的開口部1 a。通常’上述的一對咬合具i 2是利用押出成型等方法與作爲母材的帶1 1 一體成型。在此，一對咬合具〗2僅限於具有可自由開閉地密封袋本體1的咬合結構（夾鏈構造），至於構成方式並無特別的限制，譬如在本實施形態中，如第2圖所示地，是由：於其中一側具有細縫且剖面略呈C 字型的雌側咬合部1 2 a ;及可自由嚙合鬆脫地透過該細縫咬合於雌側咬合部1 2 a內部，且剖面呈箭尖狀的雄側咬合部1 2 b所構成。 •18- (14) (14)200306163 在本實施形態中，一對咬合具l 2是形成在帶1 1的表面上具備一組（一條）的結構，雖然至少具備一組咬合具1 2 ，但亦可採用譬如具備雙重咬合具1 2的雙重夾鏈構造等’ 而具有複數的咬合具12。具有複數咬合具12的夾鏈結構，因爲能更確實地保持袋本體1的氣密性，故適合作爲收納液體之類的密封袋、或必須保持高氣密性之密封袋的夾鏈結構使用。在由上述結構所構成之夾鏈1 〇的一對袋1 1的各端緣部，分別形成有突起部20(20a、20b)作爲手指防滑手段。接下來參考第1圖〜第4圖，對本實施形態中的突起部2〇作詳細的說明。如上述圖面所示地，本實施形態的突起部20，是分別形成於一對帶1 1之袋本體1開口部1 a側端緣部的一對凸肋構件。具體來說，突起部20是由形成於雌側帶1 1 a的雌側突起部2〇a、及形成於雄側帶1

(第4圖中的W )低於〇 3 mm以下，將因爲突起部太小將降低手指的牽引性，導致手指防滑手段的效能不彰。因此’在本實施形態中，面對厚度約爲0 15〜0 16腿左右的帶1 1 ’突起部2 0 a、2 0 b的尺寸，是將分別朝袋本體1內、外面側突出的最大寬度W設定爲0 3 mm以上〜帶1 1 對向面間距以下。藉由這樣的設定，使W丨与W2与0 6 7臟，一旦帶11的厚度爲0

)所示的狀態），由於開口部1 a形成開啓’故可將藥品、食品或雜貨等任意內容物收納於袋本體 1的內部。當內容物被收納入袋本體1後，可於關閉夾鏈1 0 後密封袋本體i。在封閉夾鏈i 〇的狀態下，令形成相對且 -23- (19) (19)200306163 分離狀之夾鏈10的雌側咬合部12a及雄側咬合部12b的局部相互相嵌合並以手指挾持，再由手指按壓該挾持部分使兩個咬合部12a、Kb形成咬合（請參考第2圖（a))。接著，藉由手指沿著開口部滑動，使兩個咬合部1 2 a、1 2 b 依次形成咬合，進而使整個咬合部1 2閉合。接下來，當欲開啓咬合部1 2形成咬合狀的夾鏈1 0時（如第2圖（b )所示的狀態），首先，以手指拉取袋本體1 的開口緣部，再分別以挾持位於袋緣部的一對突起部20 ( 請參考第6圖）。此時，由於突起部20是一體成型突出於袋本體1的內、外面側，故如第7圖所示地，兩個突起部 2 0 a、2 0 b，可分別由袋子的內、外側面以2隻手指確實地挾持單一位置，而突起部20將對形成挾持的指腹產生牽引。此外，由於袋本體1的開口緣部朝突起部20的外側（手指的與手掌連接的部位）延伸，故如第7圖所示地，該延伸的袋緣部也能與突起部20同時被手指所挾持。在這種狀態下，將袋本體1朝兩側拉開，將如第6圖所示地，便解除雌側咬合部1 2 a與雄側咬合部1 2b的局部咬合，直接由分離的咬合部起依次分離後解除夾鏈1 0整體的咬合後，進而解除咬合具1 2整體的咬合。藉此，可解除由夾鏈1 〇所形成的密封，並於開啓袋本體1後放入或取出內容物，當收納好內容物後，執行與上述相同的步驟關閉夾鏈1 〇，便能使袋本體1形成密封。如以上所說明地，本實施形態之具有夾鏈的密封袋，沿著用來開閉、密封袋本體1之夾鏈1 0的端緣部，具備作 -24- (20) (20)200306163 爲開啓袋子時之手指防滑手段的突起部2 0，由於這些突起部2 0與夾鏈1 〇同時被配設在較袋本體1開口部1 a更內側的位置，因此不會如傳統密封袋一般，產生夾鏈與手指防滑構造大量突出於袋子外側的情形，故能達成夾鏈及袋子整體的小型化。而且，在將含有上述突起部2〇的夾鏈10整體收納入袋本體1的本實施形態中，袋本體1的開口部更朝夾鏈1 0的外側延伸突出，備有夾鏈1 〇之開口部1 a的全體，由於被袋本體1的側面薄膜2、3所包覆，因此於開閉密封袋之際不會產生內容物外洩或異物入侵的情形，可以使開口部形成頂端密封。接著，在本實施形態中，作爲密封袋之手指防滑手段的突起部2 0，是在夾鏈1 〇貼著於袋本體1內面的狀態下，由一體成型且平均地朝袋本體1的內側面及外側面突出且剖面呈圓形的凸肋所構成，由於該凸肋是位在不會由袋本體1之開口部1 a露出的袋子內側，當開閉袋子時，可由袋子的內、外側面以2隻手指在同一位置’確實地挾持一體成型地朝袋本體1內、外面側突出的突起部2 〇。此外，由於突起部2 0位於袋本體的內側，使得袋子開口緣部朝由手指所挾持之突起部2〇的外側（手指的與手掌連接的部位）延伸，而該延伸的緣部也能與突起部2 0同時被手指所挾持。據此，本實施形態的密封袋，由於可挾持突出於袋子內、外側之突出部2 〇的同一部位，因此可以不分散力量地確實固定突起部2 〇，更由於能連帶地挾持由突起部2 〇延伸 -25- (21) (21)200306163 出的袋緣部，故能固定袋子的整個開口緣部，而不是僅將力量集中於突起部2〇。藉此，不會令手指打滑，也不會產生如習知密封袋導致指尖痛楚或麻痺的問題，能以簡易且平順的方式確實地開啓密封袋。再者，相較於傳統密封袋中分別由袋子的內側面及外側面突出的突條，由於上述可由袋子內外同時挾持同一位置的突起部2〇，可縮小朝袋本體1內、外側面突出的寬度，因此並不會產生因製作袋子的過程中突條容易傾倒導致製作不易、及突條朝袋子內側突出的長度過長導致手指不易伸入袋子開口內的問題。而，當於帶11之各緣部備有突起部20的夾鏈10熱融著於袋本體1之際，由於在本實施形態中，形成使突起部20 以外之帶1 1的其他部分融著於袋側，且突起部2 〇不會融著於袋側的構造，故能防止突起部2 0因熔解產生扁平化，使突起部2 0有效地發揮本實施形態中密封袋之手指防滑手段的功效。By sliding your finger along the opening, you can engage the concave-convex portions in order to close the entire chain. When you want to open the clip-on chain of the concave and convex part, pull the opening edge part of the bag body to both sides with your fingers, so as to release the partial engagement of the concave part and the convex part, and then separate and release from the separated engaging part in order. The whole chain of the clip is engaged so that the bag can be opened. H However, since the sealed bag with a chain as described above is made of a film such as polypropylene, the opening edge of the tape held by a finger when the chain is opened is easy to slip, especially When a person with a wet tip or low strength opens it, it is not easy to open the clamp chain due to the sliding of the fingers. Generally, in order to reliably seal the inside of such a bag, a pair of concave-convex engaging portions constituting the zipper chain will form a certain strength bite, and therefore cannot be easily opened. Therefore, it is difficult to open the traditional sealed bag that is easy to slip when the bag is gripped, especially when it is used as a medical bag for the elderly or children φ or a storage bag used by housewives to store food or groceries, it will highlight that it is not easy to open and use. Convenience issues. Therefore, in order to prevent the fingers from slipping when opening the resin-sealed bag, and to reduce the difficulty of opening the chain, a sealed bag with a non-slip structure of a finger is provided near the opening of the bag for finger pull. Figures Η and 12 show the conventional knowledge of finger slip prevention structures. 7- (3) (3) 200306163 Cross-sectional view of the sealed bag. Figure 11 is a side sectional view of the entire sealed bag. The figure is a side sectional view of an important part near the opening of the bag. The sealed bag shown in FIG. 11 is disclosed in Japanese Utility Model Publication No. 3-1 93 1 3, in which the clips constituting a pair of concave-convex bites 1 1 2 (1 1 2 a, 1 1 2 b) are disclosed. A chain 1 1 1 (referred to as a track-shaped articulator in this publication) forms a continuous fit on the outside of the opening edge portion of the resin bag body 10, and serves as a pull-out portion 1 on the outside edge portion of the clip 11 1 1 3 a, 1 1 3 b protrudes outward to form a bend, and an end portion of the pull portion 1 1 3 a, 1 1 3 b forms an enlarged portion 1 14a, 1 14b with a triangular cross-section as a finger slip prevention means. According to the structure of the sealed bag, the swelling portions 1 14a and 1 14b located on the outer end portion of the clip chain 1 1 1 can be pulled by fingers to prevent the fingers from sliding when the bag is opened, and the clip chain 1 1 1 is opened. The sealed bag shown in FIG. 12 is disclosed in Japanese Utility Model Publication No. 5-7 63 09. The method is the same as the sealed bag shown in FIG. 11, and a pair of concave and convex bites 212 (212a, The chain 211 (referred to as the orbital articulator in this publication) forms a continuous fit on the outside of the opening edge portion of the resin bag body 2 0 1 and is formed as a pull of the outside edge portion of the chain 2 1 1 2 1 3 a, 2 1 3 b, and a plurality of protrusions 2 1 4, 2 1 4 are formed on the surface of the pulling portion 2 1 3 a, 2 1 3 b as a finger anti-slip means. According to the structure of the sealed bag, since the ridges 2 1 4 and 2 1 4 on the surface of the clip chain 2 1 1 form a certain distance, the fingertips can be embedded between the plurality of ridges 2 1 4 and 2 1 4 ' This prevents the fingers from sliding when opening the bag. However, in the sealed bags with finger anti-slip structure proposed so far, as shown in Figures 11 and 12, the structure of the chain is -8- (4) (4) 200306163. The opening of the bag body is continuously fused to the outside, and the outer edge of the zipper chain forming the iu take-out portion protrudes further outward, resulting in an overall increase in the tape containing the zipper tape. Although the size of such sealed bags due to clip chains will not affect the large sealed bags used to store large items such as bedding and clothing, but for thin and light sealed bags used to store medicines, foods, etc. The impact should not be underestimated. In addition, in the structure in which the above-mentioned zipper chain is continuously formed outside the opening of the bag, since the zipper chain itself forms an opening portion, and the periphery of the zipper chain is not covered with other things, it is easy to cause the contents to overflow or foreign matter when the zipper chain is opened. Invasion, especially when used as a small sealed bag for home or medical use, containing small items, liquids, etc. Furthermore, in the sealed bag in which the above-mentioned zipper chain is formed at the end on the opening side of the bag, there is a problem that the opening portion of the bag cannot be sealed (the top end is sealed). For example, when this type of sealed bag is used as a logistics (transportation) bag, it is necessary to completely seal the inside of the bag. Therefore, the four sides of the bag including the opening on the side of the chain bag must be completely sealed. However, a sealed bag in which a chain is arranged outside the opening portion of the bag and forms a pull-out prevention portion is not suitable as a sealed bag for logistics because the bag opening cannot be sealed. However, in the sealed bag shown in FIG. 11, in the anti-slip structure provided with a protrusion (inflated portion) at the extreme end of the chain, there is no continuous part between the inflated portion and the outside, so that the force of the finger is only Being able to focus on the enlarged part, because the enlarged part strongly compresses the fingertips, it will cause pain and numbness to the fingertips as described in Japanese Patent Publication No. 5-7763. In addition, as shown in Figure i 2 of the sealed bag, -9- (5) (5) 200306163 is formed on the two sides of the pull-out part into a structure with a plurality of protrusions. 'Because the plurality of protrusions formed at different positions will be As a result, the force of the fingers is dispersed, but it is difficult for the fingers to produce the force. At this point, a type of miniaturization of the clip chain has been developed, and the device is fused to the inner surface of the bag body, and the anti-slip means such as protrusions are protruded from the bag. The internal structure is used as a means to avoid the above-mentioned problem of the conventional sealed bag in which the clip chain is continuously fused to the outside of the bag body. However, it is difficult to restrict the protrusions and the like from protruding toward the inner surface side of the bag because the clip chain is disposed alone on the inner surface of the bag body, so it cannot be sufficiently used as a finger slip prevention means. In addition, when the clip chain is fused to the bag body, the ridges and the like arranged on the inner surface of the bag will also be flattened as the clip chain melts. This may reduce the function of the finger anti-slip means. Therefore, in order to prevent the above-mentioned protrusions from being flattened due to melting, a method has been developed in which the length of the protrusions and the like is extended in advance, even if the valley solution is maintained, but the protrusions are extended in such a single place. In the structure, because the ridges are easy to fall during the process of making the bag, there are difficulties in making them, and because the length of the ridges protruding toward the inside of the bag is too long, it is difficult for the fingers to reach into the opening of the bag, but the opening and closing of the bag is reduced. Sex. This case is an invention that was developed in response to the above-mentioned conventional technical problems. The purpose of this case is to provide a protruding end portion protruding toward the body and the outer side of the bag body integrally formed at the tape edge of the tape. And by adopting an arrangement method that does not melt on the bag side, the protrusion is arranged on the inner side that will not be exposed from the opening of the bag body to prevent the chain and the entire bag from increasing in size, and to avoid problems during the manufacturing process. The flattening caused by melting can definitely improve the openability of the bag. (6) 200306163 The bag is especially suitable for sealing bags with a chain, which is used to store sealed bags such as pharmaceuticals, food, and grocery. [Summary of the Invention] In order to achieve the above-mentioned object, the seal having a zipper chain of the present invention includes: one of a bag body forming an opening; and a bag body adjacent to the body opening and forming an opposite shape along the opening of the bag body. A tape and formed on the opposite sides of the aforementioned pair of tapes can be freely tightly closed / separated to form a bite along the opening of the bag body, and one pair of concave-convex bites of the bag body can be sealed by self-closing The clip chain of the tool has a clip sealing bag, characterized in that the aforementioned pair of tapes does not form a protrusion at the end edge of the opening side of the body, but has protrusions that protrude toward the inside and the outside of the bag as a single piece. The protruding portion can be formed inside the opening of the bag body by fitting the tape to the inside of the opening inside the bag body. The sealed bag having a zipper chain having the above-mentioned structure is provided with a protruding portion as a hand sliding means when opening and closing the bag along the zipper end of the zipper body of the sealing bag body. The protruding portion is arranged in the same manner as the zipper chain. The body opening is located further inside. By arranging the chain and the protrusion on the inner side of the body, it is possible to prevent the chain and the non-slip structure from protruding a lot like the side of a conventional sealed bag, thereby achieving miniaturization of the chain and the bag as a whole. Since the clip chain including the protruding portion is formed and stored in the bag body structure, the opening edge portion of the bag body can protrude more outward than the clip chain, and the entire opening portion with the clip chain can be covered by the bag body. The bag pair with the front body with the open chain is located to prevent the bag from facing outwards, so it can be opened and closed -11-(7) (7) 200306163 to prevent the contents from overflowing when the bag is sealed Or the situation of foreign body invasion. The protruding part of the case forming the finger anti-slip means of the sealed bag is formed in a state of being attached to the inner surface of the bag body, so it can be integrally formed and protruded evenly toward the inner and outer sides of the bag body. A round, uniform ridge, which is located inside the bag that will not be exposed by the bag body. By forming the above-mentioned structure, since the protruding portions are integrally protruded from the inner and outer sides of the bag, when the bag is opened and closed, the single position can be reliably held by the inner and outer sides of the bag with two fingers. In addition, since the protruding portion is located on the inner side of the bag body, the opening edge portion of the bag is extended to the outside of the protruding portion held by the finger (the portion of the finger connected to the palm), and the extended edge portion can be simultaneously with the protruding portion. Finger held. According to the above description, since the sealed bag of the present invention can hold the same portion of the protruding portion protruding from the inside and outside of the bag, the protruding portion can be reliably fixed without dispersing the force, and the bag edge extending from the protruding portion can be held together. The portion 'can fix the entire opening edge of the bag, instead of focusing only on the protrusion. In this way, the sealed bag can be reliably opened in a simple and smooth manner, so that the fingers will not slip, and the problem of pain or paralysis of the fingertips caused by the conventional sealed bag will not occur. In addition, compared with the protrusions protruding from the inner side and the outer side of the bag in the traditional sealed bag, since the case can hold a single position at the same time from the inside and the outside of the bag, the width protruding to the inside and outside of the bag can be reduced, so it is not Problems may arise because the ridges easily fall over during the process of making the bag, making it difficult to produce, and the length of the ridges protruding toward the inside of the bag is too long, which makes it difficult for fingers to reach into the opening of the bag. And when the aforementioned pair of tapes are adhered to the inner surface of the aforementioned pocket book by heat fusion-12- (8) (8) 200306163, the 'sealed bag of this case is provided with the pair of tapes' The protrusions are not thermally fused to the inside of the bag body. Due to such a structure, when a clip chain having a protruding portion at the edge portion is thermally fused to the bag body, only a portion other than the protruding portion is fused to the bag side ', and the protruding portion is not fused to the bag side. Although the clip chain of a general synthetic resin sealed bag is integrally adhered to the bag body by thermal fusion, if the entire clip chain with a protruding portion is directly thermally fused, the protruding portion will be melted due to heat. Flattening may reduce the slip resistance of your fingers. In the present invention, by arranging a portion other than the protruding portion on the bag side, a configuration in which the protruding portion does not melt on the bag side can be formed. The efficacy of the finger anti-slip means in this case. Further, in the sealed bag of the present invention, the protrusions are formed in a direction facing the depth of the bag body and are disposed at the same position, but they may be formed at different positions. With such a configuration that the protrusions located on the inside of the bag body are opposed to each other and arranged in different positions in the depth direction of the bag body, when the chain is in an engaged state, that is, in a state of closing the sealed bag There is no interference between the opposing protrusions. In the present invention in which the protrusions do not cause the interference described above, the outer shape of each protrusion can be set to an appropriate size within the distance between the facing surfaces of the tape during the chain engagement. The size and shape of the finger can be easily applied and inserted easily, so the easy opening and closing of the sealed bag can be further improved. The size of the protruding portion of the present invention, when the protruding portion is arranged at the same position in the depth direction of the bag body, the inner side and the outer side of the bag body are -13-200306163 0) The maximum width in the protruding direction is 0 More than 3 mm ~ the distance between the opposite sides of the tape. By forming the above-mentioned structure, it is possible to maximize the engagement of the protruding portions located between the opposing faces of the tape within a range where no interference occurs. It is best to set the maximum width of the inner side and outer side of the bag body in the protruding direction to be more than 5 5 legs to less than 1/2 the distance between the opposite sides of the tape. This will make it easier to grasp, and Setting a gap between the concave and convex protrusions makes it easier for fingers to insert. In small sealed bags used for medicines and foods, although the thickness of the tape is about 0 15 to 0 16 mm, the distance between the facing surfaces of the bite-like tape is usually about 15 mm. However, because the protrusions protrude from the opposite sides of the tape and form opposing protrusions, interference between the opposite sides of the tape is generated, making it difficult for fingers to insert when opening the bag, which will damage the bag. Convenience of opening. In addition, when the protrusion is reduced in order to improve the insertability of the finger, if the protrusion width of the protrusion is less than 0.3 mm, the protrusion of the protrusion is too small, which reduces the traction of the finger, resulting in poor effectiveness of the anti-slip means of the finger. Therefore, in the present invention, for example, the thickness of the tape is about 0 15 to 0 16 bands, and the maximum width of the protruding part protruding toward the outside of the bag body is formed to be more than 0.3 to the distance between the opposite sides of the tape. The following dimensions are most suitable to be formed with a maximum width of 0.5 mm or more and 1/2 or less (approximately 0.7 mm) of the distance between the opposing faces of the tape, even if the protrusion is at the same position inside the bag body. In the state of facing the arrangement, as long as the traction of the fingers is ensured, the total protruding width of the protrusions protruding from the facing surfaces of the tape is set to be lower than the spacing of the facing surfaces of the tape (about 15 legs) is a structure that does not impair finger insertion. With this, the present invention can provide a sealed bag having a good finger pullability and easy insertion, and a good opening property. In addition, when the protrusions are arranged at different positions in the depth direction of the bag body, the size of the protrusions is such that the maximum width that protrudes toward the outer side of the body of the bag is 0.33 mm to 20 mm, in which the maximum width is 0. Above brain is most suitable. In the aforementioned state, the maximum width of the projecting portion of the bag body and the outer side is 0.3 mm or more and the distance between the tape facing surfaces, and the maximum width is more preferably 0.5 mm or more. By forming the above structure, when the protrusions are arranged in opposite positions at different positions when the chain is engaged, it is possible to form larger protrusions within the maximum range of the tape facing surfaces. As described above, when the thickness of the small sealed bag (tape) is about 0. 15 imn ~ 0 16 When awake, the distance between the opposite sides of the tape when the chain is engaged is about 15 U1II1. In addition, if the protruding width of the protruding portion is less than 0.3 leg, the traction of the finger will be reduced, and the effect of anti-slipping of the finger will be insufficient. Therefore, in the present invention, when the protrusions are arranged in opposite directions at different positions on the inside of the bag body, for example, when the thickness of the tape is about 0.15 to 016 mm, the protrusions face the bag body. The maximum width of the outer protrusion is 〇3 hidden ~ 2 〇 leg size 'of which the maximum width is formed 005 above ~ the distance between the opposite sides of the tape (about 15 legs) is most suitable. Thereby, the protrusions of the tape can form a maximum ridge in the range of the distance between the opposing surfaces of the tape without causing interference with each other, which can further improve the slip resistance of the finger and improve the seal. Convenient opening of the bag. The 'protrusions' may form raised ribs with a circular cross section or angular ribs with a cross section. In this way, the protrusions in this case are limited to the ribs that can be integrally formed. -15- (11) (11) 200306163 The ribs protruding toward the inner side and outer side of the bag body are not particularly limited in cross-sectional shape. For example, it can be a convex rib with a circular cross section, or a rectangular rib with a rectangular or rhombic cross section. In other words, according to the size of the sealed bag and the chain and the bite force of the chain, the protrusions of the present case can be selectively set to the cross-sectional shape most suitable for the sealed bag of the present case. Best-in-class and expandable sealed bag with a chain. [Embodiment] Next, the best implementation of the sealed bag with a chain in this case will be described with reference to the drawings. [First Embodiment] First, a first embodiment of a sealed bag with a chain in this case will be described with reference to Figs. 1 to 9. Fig. 1 is a simplified side cross-sectional view showing the entire bag of the sealed bag with a chain according to the first embodiment of the present invention. FIG. 2 is a side cross-sectional view showing in a simplified manner the zippered portion of the sealed bag with zippered chain according to the first embodiment of the present invention, where (a) is a state where the zippered chain is separated, and (b) is a state where the zippered chain is engaged. . Fig. 3 shows a sealed bag with a chain according to the first embodiment of the present invention, where (a) is a front view of the entire bag, and (b) is an enlarged view of a portion indicated by a dotted line in (a). Fig. 4 is a side cross-sectional view of the chain portion used to compare the size of the protruding portion of the i-th embodiment of the present invention with that of a conventional sealed bag. (A -16- (12) (12) 200306163) is the first of the present invention. In the embodiment, (b) is a conventional sealed bag. As shown in the above figures, the sealed bag with a chain according to this embodiment is composed of a bag-shaped bag body having an opening portion 1 a on one side thereof, and an opening portion 1 a attached to the bag body 1. It is composed of a sealed bag with a concave-convex snap-in clip 10 nearby. On the other hand, 5 is a pair of * 1 which is the base material of the clip key 10 attached to the inner surface of the bag body 1. The edge portion of the band 1 1 is provided with a pair of protrusions that protrude from the inside and outside of the bag and serve as a non-slip means for fingers when opening the bag 20 (20a, 20b). The bag body 1 is a bag-shaped resin bag body having an opening formed on one side thereof. Usually, the bag body 1 is formed by overlapping two resin films (female film 2 and male film 3) having a rectangular shape in a plane, or folding one resin film and then overlapping them, as shown in FIG. 3, The other 3 sides (or 2 sides) other than the 1 a side of the opening portion to be formed are bonded by means of heat fusion or the like (refer to the bonding portion 5 in FIG. 3) to form a bag shape. Here, the resin film constituting the bag body 1 is generally a film laminated with a biaxially-stretched polypropylene film and a molded polypropylene film, and is cut according to various sizes of contents to be stored. After making into bags. The opening and closing means for sealing the opening portion 1 a on one side of the bag body 1 freely opening and closing, as shown in FIG. 1, includes a pair of straps 1 arranged near the opening side 1 a of the bag body 1. 1 (1 1 a, 1 1 b), and a pair of uneven projections 12 (12a, 12b) formed on the surface of the belt 11. A pair of belts 11 is a belt-shaped member (refer to FIG. 3) attached to the inner surface of the bag body 1 in an opposite arrangement along the opening 1a. As shown in FIG. 1, The female side band -17- (13) (13) 200306163 1 1 a and the male side band 1 1 b, which are the base materials of a pair of bites 1 2a and 1 2b. Usually, the pair of bands 1 1 a and 1 1 b are formed of a synthetic resin such as polypropylene, and are adhered to the inner surface of the bag body 1 by heat fusion. In this embodiment, as shown in FIG. 3, the pair of straps 1 1 a and 1 1 b are attached to the position where the opening 1 a of the inner surface of the bag body 1 enters the inside of the bag, as described later. On the ground, the protruding portion 20 formed along the end of the belt 11 is prevented from being exposed from the opening la of the bag body 1. A pair of occlusal tools 12 are occlusal means for forming a pair of male and female pairs on each surface of a pair of belts 1 1 a, 1 1 b, which are opposite to each other, as shown in FIG. 1. The female occlusal portion 1 2 a of the female side band 1 1 a and the male occlusal portion 1 2 b forming the male side band 1 1 b are formed. The two occlusal portions 12a and 12b correspond to the inner side of the bag body 1. Opposite arrangement is formed at the same position of the body. As shown in FIG. 2, the female-side occlusal portion 1 2 a and the male-side occlusal portion 1 2 b are freely meshed to form an occlusion, so that the seal can be opened and closed freely. The opening 1 a of the bag body 1. Usually, the aforementioned pair of bites i 2 is integrally formed with the belt 1 1 as a base material by a method such as extrusion molding. Here, the pair of bites 2 is limited to a bite structure (clip chain structure) having a bag body 1 that can be opened and closed freely, and there is no particular limitation on the configuration. For example, in this embodiment, as shown in FIG. 2 The ground is shown by: a female side occlusal portion 1 2 a having a slit on one side and a slightly C-shaped cross-section; and the female side occlusion portion 1 2 a which can be freely meshed and loosely penetrated through the slit. , And the male side occlusal portion 1 2 b with an arrow-shaped cross section is formed. • 18- (14) (14) 200306163 In this embodiment, a pair of bites 12 is formed on the surface of the band 1 1 and has a structure (one), although it has at least one group of bites 1 2. However, it is also possible to employ a double bite structure having a double bite 12 and a plurality of bites 12. The zipper structure having a plurality of bites 12 can maintain the airtightness of the bag body 1 more reliably, so it is suitable for use as a zipper structure for a sealed bag containing a liquid or a sealed bag that must maintain high airtightness . Protrusions 20 (20a, 20b) are formed on each end edge portion of the pair of bags 11 of the zipper chain 10 constituted by the above-mentioned structure as a finger slip prevention means. Next, referring to Fig. 1 to Fig. 4, the protruding portion 20 in this embodiment will be described in detail. As shown in the above drawings, the protruding portions 20 of this embodiment are a pair of rib members formed at the edge portions on the side of the opening portion 1a of the pair of bag main bodies 1 of the belt 11 respectively. Specifically, the protruding portion 20 is composed of a female-side protruding portion 20a formed on the female-side belt 1 1 a and a male-side protruding portion 20b formed on the male-side belt 1 lb, and two protruding portions 20a And 20b are arranged along the openings 1a, respectively, and are arranged in opposite directions at the same position in the depth direction of the bag body 1. The projections 20a and 20b are integrally formed to protrude from the inner and outer sides of the films 2 and 3 constituting the bag body 1, respectively. In this embodiment, a circular cross section as shown in Figs. 1 and 2 is formed. Raised ribs. Here, as shown in FIG. 4, the protrusion 20 having the circular cross section has a width (Wi and W2 in FIG. 4 (a)) that protrudes toward the inside and outside of the bag body 1. The sum of the maximum widths (W in Figure 4 (a)) formed in the protruding direction of the inside and outside of the bag is about 0 3 inm or more ~ Band -19- (15) (15) 200306163 1 1 Opposite Below the interplanar distance, among them, it is more than 0.05 min. ~ I / 2 below the 11-opposite interplanar distance is most suitable. Generally, in small sealed bags used as medicine or food, when the thickness of the tape (1 1 a, 1 1 b) is about 5 sides, the opposite side of the tape that is in the form of a bite when the chain is engaged The distance between faces is usually about 15 legs. In this embodiment, 'the protrusions 20a, 20b are facing each other at the same position on the inner surface of the bag.' Once the protrusions interfere with each other between the opposing surfaces of the tape, it will be turned on. It is difficult to insert the fingers between the protrusions when the bag is in use, which is detrimental to the convenience of opening the bag. In addition, if the total width (W in FIG. 4) of the protruding portion 20 protruding toward the outer side of the bag (W i in FIG. 4) and the inner side (W 2 in FIG. 4) is less than 0.3 mm, Because the protrusion is too small, the traction of the finger will be reduced, and the effectiveness of the anti-skid means of the finger will be poor. Therefore, in this embodiment, the sizes of the protrusions 2 0 a and 20 b facing the belt 1 1 having a thickness of about 0 15 to 0 16 legs are projected toward the inside and the outside of the bag body 1, respectively. The maximum width W is set to be greater than or equal to 0 3 mm and less than or equal to the pitch of the facing surfaces. With this setting, W 丨 and W2 and 0 6 7 are dirty. Once the thickness of the belt 11 is 0 15〇1111, \ ^ and 067 (\ ¥ 1) +067 (\ ^ 2) + 〇15 (band 11 thickness) and 15 legs (\ ¥), so even the largest total protruding width (W) is lower than the distance between the opposite sides of the band 11. In addition, the maximum width W is preferably set to be not less than 0 5 mm and not more than 1/2 of the distance between the facing surfaces of the band 11 (about 0 7 legs). When the above state is formed, for example, when W 1 and W 2 and 〇 2 8 _, plus the thickness of the belt 1 〇 1 5 mm, W and 0 28 (Wi) + 〇28 (W2) + 0 15 (band 11 Thickness) and 0 7mm (W), even the largest total protruding width (W), is lower than 1/2 of the band 11 pair -20- (16) 200306163 face to face distance. In this way, even if the protrusions 20 a and 20 b are arranged in the same position on the inside of the bag body, the protrusions of the protrusions between the facing surfaces of the belt 11 can be ensured while ensuring the traction of the fingers. The width is set to the distance between the opposite sides of the band 11 (about 15 legs) to form a structure that does not damage the finger insertion. With this, in this embodiment, the pair of protrusions 20a and 20b used as the anti-slip means for the fingers can be made larger without causing interference with each other, thereby ensuring the finger pullability and easy insertion. In good condition, the protrusions 20 integrally formed and evenly facing the inside and outside of the bag body 1 are formed so that two fingers can be held in a single position by the inside and outside of the bag, as shown in FIG. 4. In the traditional bag (please refer to Figure 12), the protruding width of the protrusions on the inner side of the bag and the outer protrusions (^ and W2 in Figure 4 (b)) can be used on the inner side and outer side of the bag. In this way, the total width of the protrusions can be made smaller than that of the conventional 値 (please refer to (a) and (b) in Figure 4). Therefore, a sealed bag with a protruding portion 20 of this embodiment is provided, and In the process of not making the bag body 1, it is difficult to produce because the protrusions are dumped. The length of the protrusions protruding to the inside of the bag is too long, which makes it difficult for fingers to reach into the openings, and it is possible to efficiently produce small and excellent seals with excellent openability. 〇 Further, in this embodiment, although the The front pair of tapes 11 is adhered to the inner surface of the bag body 1, but is formed on the tape portion 1 1 without being fused to the bag body 1. In other words, in this embodiment, when the tape 1 1 The clip chain with the protrusion 20 at the edge 1 0 The range of knots at the same time below which it is thermally fused becomes the narrowest protrusion of the sealing surface on the sealing surface W) It will be described in or due to the sealing bag inside When carrying out the pouch-21-(17) 200306163 on the body 1 side, only the protrusions 20 other than the band 1 1 will be affixed to the pouch side (please refer to the synthetic resin made in this embodiment) The clip chain 10 is the same, and is integrally formed by thermal fusion. If the entire clip chain 20 having the protruding portion 20 is directly thermally fused, the flattened portion may be flattened, which may cause a reduction. Therefore, in this embodiment, In this case, by making the zipper tape 11 melt on the bag side, forming the protruding portion 20 can prevent the flattened effect of the protruding portion 20 from being melted and exert the effect of the slip prevention means of the finger. The clip chain 10 is inside the bag body 1, and the opening edge portion of the bag body 1 faces toward the clip, so it can be When the opening edge portion is fused to form a top-end bag for use as a logistics (transportation) bag, the inside of the bag including the zipper bag-side opening must be included in the sealed bag of this embodiment because the bag body 1 I 1 〇 The outer side protrudes, so that the top end seal is formed after thermal fusion as shown in Fig. 5 (see Fig. 5). With the provision of the protruding portion 20, there is no need for a sealed bag for logistics that requires high sealing properties. There are no particular restrictions on the shape and number of the protruding portions 20 in this embodiment, although the ribs having a cross-section are formed one at a time on the belt 1 1 and project toward the inner and outer sides of the bag body. Examples The part will melt on the bag side (Figure 2). It is the same as the general sealed bag F in the bag body 1, but if the protruding portion 20 of the finger 10 is slipped due to heat, the protruding portion 20 will be melted, so that the protruding portion 20 can be formed and stored as a whole. A protruding seal is extended on the outside of the chain 10. When this type of seal is used to completely seal the bag, the four sides are completely sealed. The edge of the opening is facing the chain, and the edge of the opening can be damaged; Figures (a) and (b) impair the tightness of the top end, as described above, it has a circle and is limited to integral ribs, but its cross section : As shown in Figure 8, -22- (18) (18) 200306163, the protrusion 20 can be a square section with a square shape (Figure 8 (a)) or a diamond (Figure 8 (b)). Raised ribs. The number of the protrusions 20 may be, for example, a plurality of pieces formed on the end edge portion of each band 11 as shown in FIG. 9. As described above, in the present embodiment, when the thickness of the belt 11 is about 0 1 5 to 0 1 6 legs, each protrusion 20 corresponds to the distance between the facing surfaces of the belt 11 (about 15 legs). The maximum width W is equal to or less than the distance between the facing surfaces of the belt 11 (about 15 mm). Of course, this thickness can be appropriately changed according to the thickness of the belt 11 and the spacing between the facing surfaces of the belt 11. For example, when the distance between the facing surfaces of the belt 11 is larger than 15 legs, the maximum width of each protruding portion 20 may be larger than 15 surfaces. In this way, the shape, number, and size of the protrusions 20 can be variously changed. Depending on the conditions such as the bite force of the fastener chain, the size of the bag body 1 and the fastener chain 10, the protrusions 20 can be selectively set to suit the cost. The sectional shape and number of the sealed bags of the embodiment. Next, the opening and closing operation of the sealed bag with a chain in the present embodiment configured as described above will be described with reference to FIGS. 2, 6 and 7. Fig. 6 is a perspective view showing the unsealing operation of a sealed bag with a chain in the first embodiment of the present invention, which is a perspective view seen from above the bag. Fig. 7 is a diagram showing the unsealing operation of the same sealed bag with a chain. Explanatory diagram of the cross section. First, when the zipper chain 10 provided in the bag body 1 is in the disengaged state (such as the state shown in FIG. 2 (a)), since the opening portion 1a is formed to be opened, medicines, foods, and grocery products can be opened. Arbitrary contents are stored inside the bag body 1. After the contents are received in the bag body 1, the bag body i can be sealed after the clip chain 10 is closed. In a state where the clamp chain i 〇 is closed, parts of the female-side occlusal portion 12 a and the male-side occlusal portion 12 b forming the oppositely-shaped -23- (19) (19) 200306163 are separated from each other and are fitted with fingers. Hold, and then press the holding part with your fingers to make the two occlusal portions 12a, Kb occlude (refer to Figure 2 (a)). Next, by sliding a finger along the opening portion, the two occlusal portions 1 2 a and 1 2 b are sequentially formed into occlusions, thereby closing the entire occlusal portion 12. Next, when the occlusal portion 12 is to be opened to form an occluded clip chain 10 (as shown in FIG. 2 (b)), first, pull the opening edge portion of the bag body 1 with your fingers, and then Hold a pair of protrusions 20 at the edge of the bag (refer to Figure 6). At this time, since the protruding portion 20 is integrally formed to protrude from the inner and outer sides of the bag body 1, as shown in FIG. 7, the two protruding portions 20a and 2b can be respectively formed from the inside and the outside of the bag. The side is surely held in a single position with two fingers, and the protrusion 20 will cause traction to the fingertips forming the hold. In addition, since the opening edge portion of the bag body 1 extends to the outside of the protruding portion 20 (the portion of the finger that is connected to the palm), as shown in FIG. 7, the extended bag edge portion can be simultaneously held by the protruding portion 20. Finger held. In this state, the bag body 1 is pulled apart on both sides, and as shown in FIG. 6, the partial engagement between the female occlusal portion 12 a and the male occlusal portion 12 b is released, and the occlusal portion is directly engaged by separation. After the parts are sequentially separated, the entire occlusion of the clamp chain 10 is released, and then the entire occlusion of the occluder 12 is released. Thereby, the seal formed by the clip chain 10 can be released, and the contents can be put in or taken out after opening the bag body 1. After the contents are stored, the same steps as described above are performed to close the clip chain 10. The bag body 1 is sealed. As described above, the sealed bag with a zipper chain of this embodiment is provided along the end edge portion of the zipper chain 10 for opening and closing and sealing the bag body 1, and is provided with -24- (20) (20) 200306163 as The protrusions 20 of the anti-slip means of the fingers when the bag is opened, because these protrusions 20 and the chain 10 are arranged at a position more inward than the opening 1 a of the bag body 1, they will not be as common as conventional sealed bags. As a result, a large number of clip chains and finger anti-slip structures protrude outside the bag, so the miniaturization of the clip chain and the bag can be achieved. In addition, in the present embodiment in which the clip chain 10 including the protruding portion 20 is entirely incorporated into the bag body 1, the opening portion of the bag body 1 is further extended to protrude outside the clip chain 10, and the clip chain 10 is provided. Since the entire opening portion 1 a is covered by the side films 2 and 3 of the bag body 1, when the sealed bag is opened and closed, no leakage of contents or invasion of foreign materials occurs, and the opening portion can be sealed at the top end. Next, in this embodiment, the protruding portion 20 serving as a finger anti-slip means for the sealed bag is integrally formed and evenly faces the bag body 1 in a state where the chain 10 is attached to the inner surface of the bag body 1. The inner side and the outer side are formed by convex ribs with a circular cross-section. The ribs are located inside the bag which will not be exposed by the opening 1 a of the bag body 1. When the bag is opened and closed, the inner and outer sides of the bag can be opened and closed. The outer surface is firmly held integrally with two fingers at the same position, and the protruding portion 2 protruding toward the inside and the outside of the bag body 1 is integrally formed. In addition, since the protruding portion 20 is located on the inner side of the bag body, the opening edge portion of the bag extends toward the outside of the protruding portion 20 held by the finger (the portion of the finger connected to the palm), and the extended edge portion can also be connected with The protrusions 20 are simultaneously held by fingers. According to this, the sealed bag of this embodiment can hold the same portion of the protruding portion 20 protruding from the inside and outside of the bag, so that the protruding portion 20 can be reliably fixed without dispersing the force, and the protruding portion can be held by the protruding portion. 〇Extending the edge of the bag from -25- (21) (21) 200306163, so that the entire opening edge of the bag can be fixed, instead of focusing only on the protrusion 20. This prevents the fingers from slipping, and does not cause problems such as pain or numbness in the fingertips caused by the conventional sealed bag. The sealed bag can be reliably opened in a simple and smooth manner. Furthermore, compared with the protrusions protruding from the inner side and the outer side of the bag in the conventional sealed bag, the protrusions 20 at the same position can be simultaneously held by the inside and the outside of the bag, which can reduce the protrusion toward the inner and outer sides of the bag body 1. Therefore, the problem that the protrusions are easy to fall during the process of making the bag and the production is not easy, and the length of the protrusions protruding to the inner side of the bag is too long, which makes it difficult for the fingers to protrude into the opening of the bag. On the other hand, when the clip chain 10 provided with the protrusions 20 on each edge portion of the band 11 is thermally fused to the bag body 1, in this embodiment, the other parts of the band 11 other than the protrusions 20 are formed to be fused. Structure that sticks to the bag side and the protruding part 20 does not melt on the bag side, so it can prevent the protruding part 20 from flattening due to melting, so that the protruding part 20 effectively exerts the non-slip of the sealed bag in this embodiment. Means of efficacy.

Fig. 10 'is a simplified side cross-sectional view showing a bag with a zippered sealed bag according to a second embodiment of the present invention. The sealed bag with a clip chain of this embodiment in the figure is a derivative example of the above-mentioned -26- (22) (22) 200306163, and the first embodiment is arranged at the same position inside the bag body 1 The opposing protrusions 20 are provided at different positions in the depth direction of the bag body 1. The other structural parts are the same as those of the first embodiment. Therefore, the same parts are marked with the same drawing numbers as those of the first embodiment, and detailed descriptions of the parts are omitted. Specifically, as shown in FIG. 10, the protruding portion 20 in the present embodiment has the male-side protruding portion 20 b protruding from the female side in the depth direction (up and down direction in the drawing) of the bag body 1. The position of the portion 20 a on the inner side is such that the two protruding portions 20 a and 20 b are offset by about 1 in the depth direction of the bag body 1. However, this embodiment is the same as the first embodiment. The width of the protruding portion 20 having a circular cross-section toward the inside and outside of the bag body 1 (one in FIG. 4 (a)! And W2) is approximately equal. The sum of the maximum widths in the protruding direction of the inside and outside sides of the bag (W in Fig. 4 (a)) is about 0.3 mm to 20 legs, and more than 0.5 legs is the most suitable. As described above, in the small-sized sealed bag, when the thickness of the belt 11 is about 0 1 5 mm to 0 16 min, the distance between the facing surfaces of the belt 11 when the chain is engaged is about 15 minutes. In addition, if the protruding width (W) of the protruding portion 20 protruding toward the bag outer side (W i) and the bag inner side (W2) is less than 0.3 mm, the traction of the fingers will be reduced, and the anti-slip effect of the fingers will be ineffective. Therefore, in this embodiment, the protrusions 20 are arranged at different positions on the inner surface of the bag body so that the maximum width W protruding from the inside and outside of the bag body 1 is 0 3 nun. Above ~ 2 〇_, the maximum width of which is more than 0 5 bands ~ 15 legs (the distance between the 11 facing surfaces is the best). -27- (23) (23) 200306163 At the position where no interference is formed between the protrusions 20 that form opposite shapes, the maximum can be W 丨 and W 2 and 15 mm. Once the thickness of the belt 11 is 0 丨 5 When _, w and 1 5 + 15 and 30 mm, so W can be set to a maximum of 2 times the distance between opposite sides of the band. Therefore, if W exceeds 20 inm, it will be difficult for fingers or hands to enter, which may damage the opening performance. Therefore, in this embodiment, by arranging the protrusions 20 at different positions in the bag body 1, interference between the protrusions can be avoided, and the distance between the facing surfaces of the belt 11 without impairing the sealability can be prevented. The protrusion 20 is set to the largest within the range. However, in this embodiment, the maximum width w of each protruding portion 20 corresponds to a maximum of 20 legs, corresponding to the distance between the facing surfaces of the belt 11 (about 15 legs), of which 15 irnn is the most suitable, but this 値Same as the first embodiment, of course, it is possible to appropriately change the distance between the facing surfaces of the belt 11. For example, when the distance between the facing surfaces of the belt 11 is greater than 15 mm, the maximum width of each protrusion 20 can be set. It is more than 〇3 IM to less than the facing distance. In the position where different protrusions 20a and 20b are formed in the depth direction of the bag body 1, although a deviation of 1 band is formed in this embodiment, the protrusions 20, 20, and the bag body 1 may also be used according to the bite 12. Make appropriate changes to the size and style. As described above, since the sealed bag with a chain in this embodiment is formed with the protrusions 20 formed on the inner surface of the bag body 1 facing each other, it is arranged at different positions in the depth direction of the bag. 12 The occluded state, that is, the state in which the sealed bag is closed, does not cause interference between the opposed protrusions. With this, the shape of the protrusion portion 20 in this embodiment can be set to an appropriate size within the range D of the facing surface of the tape when the chain is engaged, since the protrusion portion can form a finger and is easy to apply force and Easy to insert -28- (24) (24) 200306163, which can further improve the easy opening and closing of the sealed bag. [Example] Next, the present invention will be described in detail by comparing the examples with some examples. Zippered sealed bag. Compared with the sealed bag described in the above embodiment, the following implementation force is a sealed bag made according to specific conditions described later. [Example 1] The chain (belt and articulator) was made of polypropylene. The protrusion at the end of the belt has a circular cross section, and the diameter of the circular cross section is 0 3 mm. The positions of the protrusions correspond to the sealed bag of the first embodiment, and the male side and the female side are located at the same position. The bag body is a film laminated with a biaxially stretched polypropylene film and a molded polypropylene film.

Whether the protrusion is deformed after making: ◎ No deformation; △ Slightly deformed (fall over) (29) (29) 200306163 As shown in Table 1, first, as shown in Example 1, when the protrusion is located on the male side At the same position on the female side band and the diameter of the protrusion was 0 3 min, although the pulling feeling was slightly inferior, the finger insertability was judged to be good. On the other hand, as shown in Examples 2 and 3, the diameter of the protruding portion was in the range of 5 to 0.7 nm, and the result of the determination was that the finger was easy to pull and the finger insertability was good. As shown in Examples 4 and 5, the diameter of the protruding portion is in the range of 10 to 15 legs', although the finger insertability is slightly inferior, the pulling feeling is good. Within the above range, it is not as common as Comparative Example 1, because the diameter of the protruding portion is reduced, which results in poor pull-out feeling. It is also not the same as Comparative Example 2, and the finger insertion is not caused by increasing the diameter of the protruding portion. good. As shown in Examples 6 to 9, by setting the positions of the male and female protrusions to be offset by 1 to 2 mm, the diameter of the protrusions can be set to a maximum of 20 mm. As a result, it was determined that the convenience of pulling and finger insertion can be further improved. On the other hand, as shown in Comparative Example 3, the diameter of the protruding portion is too large, resulting in poor pulling and finger insertion, but it does not cause problems such as tipping and deformation due to melting of the protruding portion during the manufacturing process. In addition, the sealed bag with a chain of the present invention is not limited to the above-mentioned embodiment, and can be variously changed within the scope disclosed by the present invention. For example, although in the above-mentioned embodiment, a small sealed bag for storing medicines, food, or groceries is taken as an example, it is not limited to the above-mentioned uses and objects, as long as it is made of a synthetic resin that can be sealed. The zippered sealed bag with a zipper inside the bag body is applicable to the present invention regardless of its use and function. Therefore, it is not only a small sealed bag, whether it is a larger sealed bag; a sealed bag provided with a nozzle for discharging and suppressing the air in the bag -34- (30) (30) 200306163; or a sliding bag Various sealed bags with a chain, such as a sealed bag of a zipper opened by a chain, are applicable to the present invention. [Effects of the Invention] As described above, the sealed bag with a chain of the present invention is A tape edge is provided integrally with a protruding portion protruding toward the inside and outside of the bag body, and the protruding portion is arranged so that it does not melt on the bag side. The inner side exposed from the opening of the bag body can prevent the size of the chain and the entire bag from being enlarged, and can avoid flattening due to melting during the production process, and can reliably improve the openability of the bag. Therefore, it is particularly suitable for a sealed bag with a chain to store small sealed bags such as medicines, foods, and groceries.
