Description of the invention (1) ^ ~ ---- ^ [Technical Field] * The present invention relates to a bag with a zipper and its switch accessories, especially to a device with a zipper. A zipper bag and its switch fittings which are formed by the concave and convex portions which can be fitted to each other in the opening portion. [Know-how] In the past, bags made of plastic films have various bags with chains as shown in Fig. 18a. The bag i shown in Fig. 18a is provided with a zipper 4 composed of a concave portion 4a and a convex portion 4b which can be fitted to each other on the upper part of the mask 2 and the back film 3. This bag is called a top zipper bag. This top zippered bag is opened and closed by a switch slide 900 shown in Fig. 19a. In the bag 1 shown in Fig. 18b, the zipper 4 is composed of a concave portion 4a and a convex portion 4b which are integrally formed on the inside of the upper portions of the adhesive films 2, 3, respectively. The bag 1 shown in Fig. 18c is composed of a concave portion 4a and a convex portion 4b which are fixedly attached to the inner sides of the upper portions of the films 2 and 3, respectively, to constitute the slide fastener 4. As shown in Figs. The bags 1 shown in Figs. 18b, 18c, and 18d include sealing portions 2a, 3a extending upward from the zipper 4 at the upper ends of the adhesive films 2, 3. The sealing portions 2a, 3a can be opened by grasping with fingers. . Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. However, the bag 1 shown in Figs. 18b, 18c, and 18d is a closed zipper 4, which must be aligned with the concave and convex portions 4a and 4b and pressed with fingers from both sides (control arrow a). Slide your finger along the uneven portions 4a, 4b. In addition, in order to open the zipper. 4, it is necessary to grasp the openings 2a, 3a with fingers to forcibly release the fitting of the uneven portions 4a, 4b. However, the opening and closing operations of such a bag 1 are very troublesome, so there is currently a need for a switch accessory that can be opened and closed by a simple operation. On the other hand, recently, as shown in Figs. 18b, 18c, and 18d, a bag 1 in which the opening portions 2a, 3a are cut with a one-point chain line has appeared. This kind of bag 1 series 3 This paper size is applicable to Chinese National Standard (CNS) A4 specification (210 X 297 mm) 516946 Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 B7 V. Description of the invention (>) The opening parts 2a, 3a can be cut and opened using a switching accessory 900 as shown in FIG. 19a to open and close the bag, that is, a bag similar to the top zipper type. Using a switch accessory 900 similar to the top zipper bag, as shown in FIG. 19b, when the zipper 4 is opened and slid to one end of the bag 1, about half of the part will protrude beyond one end, that is, There is a lack of stability. In order to solve such a problem, a stopper was fixedly installed at the end of the bag, or the end was temporarily fused by high-frequency welding to form a protruding portion, which functions as a positioning portion of the switch fitting 900. However, the installation of the stopper or part of the melting work must be performed manually, and the operation steps increase, resulting in increased costs. In addition, the protruding portion formed as the positioning portion has the risk of hurting hands, and cannot be used in bags such as children's or women's clothing. In addition, the switch fitting 900 is easy to slide in a direction shown by an arrow a as shown in Fig. 19a, and lacks stability. Furthermore, the aforementioned similar top zipper bag is shown in Figs. 18b and 18d. Even if the opening portions 2a and 3a are cut with a little chain line, there will still be some opening portions 2a 'and 3a', and this residual portion 2a ', 3a' will rub against the top of the switch fitting and have the disadvantage of so-called "kelp-like" deformation.

中腳片兩側在上部與中腳片連結之一對側腳片，及中腳片 和位於各側腳片間與打開部之插通溝部構成之開關配件。 此開關配件，係由中腳片插入前述拉鏈之凹部及凸部之間 ，側腳片透過前述打開部以壓接於凹部及凸部之狀態安裝 於前述本體開口部，沿著拉鏈滑動即可開關拉鏈。 上述構成中，將開關配件滑向一端中腳片即進入拉鏈 之凹部及凸部將兩者強制性的分離，以打開袋本體之開口 部。又，將開關配件滑向另一端，一對側腳片即由外側壓 向凹部及凸部令其嵌合，以閉合本體之開口部。 經濟部智慧財產局員工消費合作社印製 更進一步，亦可在本發明中開關配件之中腳片之開放 側部位裝設一切割部。如預先將袋之打開部熔接或貼上封 口用貼紙，初次滑動開關配件時，切割部即將熔接部份或 封口用貼紙切開。因此，如將此袋作爲限本人開封用之封 套，可立刻判斷是否未開封或已遭他人開封。 再者，本發明具拉鏈之袋，如將前述開關配件安裝於 拉鏈基材上，再將袋本體之面膜及背膜延伸至開關配件上 _ 5 本紙張尺度適用中國國家標準（CNS ) A4規格（210X 297公釐） 516946 A7 五、發明説明（斗） 的話，將此延伸部份熔接即可成爲完全密閉式。此時，祇 要將拉鏈基材之下半部熔接於面膜及背膜即可。 再者，本發明中，最好在開關配件之中腳片下部形成 一突出部。將此突出部抵接在類似頂拉鏈式袋之拉鏈部2 凹部及凸部的下面安裝於拉鏈上，以此狀態確保開關配件 之安定性，防止滑動。又，拉開拉鏈將開關配件滑至袋端 部時，此突出部抵接於袋端部阻止其進一步的移動，即使 不裝設定位部也可防止開關配件自袋端部突出之缺點。因 此，如以往般安裝擋塊、以熔接器熔融形成定位部之時間 即可省略。 再者，最好在本開關配件之中腳片上形成一膨出部， 藉此膨出部或前述定位部抵接於拉鏈下面，可防止自拉鏈 滑脫。而且以中腳片插入拉鏈之凹部及凸部，可將之安裝 於成品袋之拉鏈上，最適合用於量產性佳之熔斷袋上。 經濟部智慧財產局員工消費合作社印製 再者，開關配件中，最好於前述中腳片及側腳片之連 結部上，形成一對向於拉鏈上面之突起較佳。如於開關配 件之頂部形成一突起，此突起能發揮隔離空間之作用，消 除打開部殘留部份摩擦頂部所造成之變形。又，因摩擦面 縮小，開關配件之滑動效果更佳。 【發明之實施形態】 以下，針對本發明相關之具拉鏈之袋之實施形態，對 照附圖作一說明。 圖1係本發明之一實施形態，顯示安裝有開關配件 10A之具有拉鏈之袋。此袋係將塑膠膜以熔斷或熔接切斷 -_- —_ 6 本紙張尺度適用^"^家標準（〇泌）八4規格（210、乂 297公釐）~~"" -- 516946 A7 B7 五、發明説明（< ) 方式製成之眾所周知之袋。 開關配件10A係由樹脂材料以射出方式一體成型之物 ，其第1實施形態如圖2所示，由中腳片11及位於其兩側 之一對側腳片21構成。中腳片11與側腳片21在上部連結 ，形成有可插通打開部2a、3a之溝部29。 中腳片11在其中段部兩面形成有溝部12 ’在此溝部 I2上可嵌入拉鏈4之凹部牝及凸部4b。又，溝部12的上 下緣部形成有膨出部13、14，且拉鏈4之打開方向（參照 圖2e)爲一切口 15。 一對側腳片21，以自兩側夾住中腳片11的形態組合 ，在面對前述切口 15之部位形成有膨出部22。 經濟部智慧財產局員工消費合作社印製 由上述構造組成之開關配件10A，利用其可撓性，對 拉鏈4已打開之袋1，將中腳片I1插入打開部2a、3a間 ，使膨出部14強制性的越過凹部4a及凸部4b(參照圖3a 、b)，而作安裝。此時，如圖3a所示，嵌入切口 15之凹 部4a及凸部4b，被膨出部22擠壓在切口 15內互相嵌合 。又，如圖3b所示，嵌入溝部12之凹部4a及凸部4b， 藉中腳片11分離，且位於與側腳片21所形成之空間內。 打開部2a、3a位於溝部29。 如此，安裝於袋1之開關配件l〇A，因凹部4a及凸部 4b嵌入溝部12及切口 15，且被側腳片21由兩側夾住，因 此不致向上方脫離。當然，如以手指將側腳片21向外側壓 開使之彈性變形，自可將開關配件10A自袋上取下。但， 只要不使其形成如般，即使將開關配件10A向上拉亦不至 度適用f關家標準（CNS ) A4規格（21GX 297公| ) ~ ' 516946 A7 B7 五、發明説明（卜） 取下開關配件10A。 以開關配件10A所作之開關動作如下。 將開關配件10A滑向溝部I2形成之方向（參照圖2e) ，凹部4a及凸部4b被膨出部22擠壓進入切口 15相互嵌 合。如此拉鏈4即被閉合。另一方面，將開關配件i〇A滑 向與此相反的方向，凹部4a及凸部4b被中腳片u、即被 溝部12的底部分離部12a(參照圖2e)強制分離，亦即拉鏈 4被打開。 再者，爲更進一步發揮前述開關配件10A之機能，能 採用以下結構。 側腳片21外面形成一小小凹入之三角形記號23(參照 圖2a)。此記號23代表將開關配件10A滑向其頂角方向即 可閉合拉鏈4。當然，亦可以印刷等方式賦予此類記號。 中腳片11及側腳片21之下端爲細尖形狀，所有的角 部均爲圓角。此係爲方便安裝開關配件10A及使其滑動更 爲順暢。與此同理，膨出部14係形成向下方漸漸細狹。 經濟部智慧財產局員工消費合作社印製 又，在溝部12的上下緣部形成之膨出部13、14中至 少有一不是形成於中腳片11，而是形成於側腳片21之內 面亦可。圖4係顯示取代膨出部13，而於側腳片21內面 形成膨出部13’之第2實施形態之開關配件1〇Β°

In addition, when the zipper is opened to slide the switch accessory to the end of the bag, the protrusion abuts on the end of the bag to prevent further movement. Even if the setting part is not installed, the disadvantage of the switch accessory protruding from the end of the bag can be prevented. Therefore, it is possible to omit the time required to attach the stopper as usual and to form the positioning portion by fusing. Furthermore, it is preferable to form a bulging portion on the leg piece of the switch accessory, whereby the bulging portion or the aforementioned positioning portion abuts under the zipper to prevent the zipper from slipping off. In addition, the concave part and the convex part of the zipper are inserted with the middle leg piece, and the zipper can be installed on the zipper of the finished bag, which is most suitable for the fuse bag with good mass production. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. Furthermore, it is better to form a pair of protrusions facing the zipper on the connecting part of the aforementioned middle leg piece and side leg piece. If a protrusion is formed on the top of the switch accessory, this protrusion can play a role of isolating space and eliminate the deformation caused by the remaining part of the opening part rubbing the top. In addition, due to the reduced friction surface, the sliding effect of the switch accessories is better. [Embodiments of the invention] Hereinafter, embodiments of the bag with a zipper according to the present invention will be described with reference to the drawings.

The description of the invention () The sliding phenomenon shown by arrow a in 19a. The opening / closing operation of the zipper 4 by the aforementioned opening / closing accessory 310 is as follows. Slide the switch fitting 310 in the direction of "close" shown by the arrows in Figs. 13d and 15, and the concave portion 4a and the convex portion are pressed inward by the pressurizing portions 323 and 323, and then fit into the cutout portions 313. With this operation, the zipper 4 is closed (see FIG. 17b). On the other hand, when the switch fitting 310 is slid in the opposite direction (in the direction of "open" indicated by the arrow), the concave portion 4a and the convex portion 4b are forcibly separated by the separation wall portion 312. That is, the slide fastener 4 is in an opened state (see FIG. 17a). In this open state, although the switch accessory 310 is located at one end of the bag 1, but because the top of the protruding portion 315 of the middle leg piece 311 abuts the end of the bag, the switch accessory 310 does not occur as shown in FIG. 19b. One of the problems stands out. Furthermore, protrusions 316 and 317 are formed on the top of the switch fitting 310 at the top where the middle leg piece 311 and the side leg piece 321 are connected. The protrusions 316 and 317 are opposed to the upper surface of the zipper 4 (see Fig. 17), and can prevent the top of the switch fitting 310 from contacting the cutting residues 2a ', 3a' of the adhesive films 2, 3, and function as spacers. Therefore, the cutting residues 2a ', 3a' are not deformed into a "kelp shape". In addition, since the switch fitting 310 is inserted into the concave portion 4a and the convex portion 4b of the zipper 4, the foot piece 3U can be easily installed on the existing bag 1 afterwards. This means that the switch fitting 310 can also be installed on the fuse bag with good mass production, greatly expanding the use of the switch fitting 310. Therefore, once the switch fitting 310 is mounted, the bulged portion 314 and the protruding portion 315 abut against the lower surface of the zipper 4, so that the detachment from the zipper 4 is prevented. ^--ϋ ____ This paper size applies to China National Standard (CNS) A4 specification (2 丨 〇 > < 297mm) (Please read the precautions on the back first to complete this page) Printed by the Consumer Cooperative of the Property Bureau A7 ________B7 V.
