Description

本発明は、閉止専用スライダ、特に、樹脂フィルム製袋の開口部に設けたジッパーを閉止するために使用される閉止専用スライダに関する。 The present invention is closed only slider, in particular, to closed dedicated slider which is used to close the zipper provided on the opening portion of the resin film bag.

従来、樹脂フィルム製袋として、図９に示す袋１が知られている。この袋１は樹脂フィルムを溶着して側部をカット、あるいは溶断したものであり、開口部２に位置する一対のフラップ部３，３の対向する内面に、互いに嵌合／解除可能な凹部８ａと凸部８ｂとからなるジッパー８を設けたものである。なお、ジッパー８の凹凸部８ａ，８ｂの構造、形状には種々のものがある。   Conventionally, a bag 1 shown in FIG. 9 is known as a resin film bag. This bag 1 is formed by welding or cutting a side part by welding a resin film, and a recess 8a that can be fitted / released on the opposing inner surfaces of a pair of flaps 3 and 3 located in the opening 2. And a projection 8b. There are various structures and shapes of the uneven portions 8a and 8b of the zipper 8.

この種のプラスチック製袋１のジッパー８を開閉するには、（１）フラップ部３，３を指でつまんで開放し、閉止は専用のスライダで行う、（２）一方向にスライドさせることで閉止し、他方向にスライドさせることで開放する開閉用スライダを使用する、（３）開閉共に指で行う、の３通りの方法がある。   To open and close the zipper 8 of this kind of plastic bag 1, (1) pinch the flaps 3 and 3 with your fingers and close with a special slider, (2) slide in one direction There are three methods: using an open / close slider that closes and opens by sliding in the other direction, and (3) opening and closing with a finger.

前記（１）で使用される閉止専用スライダの一例を図１０に示す。この閉止専用スライダ１０は、前記フラップ部３，３の外側に位置する一対の側脚片１１，１１と、フラップ部３，３の内側に位置してジッパー８には届かない長さの中脚片１５とを備えている。このスライダ１０がいずれかの方向にスライドすることにより、側脚片１１，１１の内側に形成した凸部１２，１２がジッパー８の凹凸部８ａ，８ｂを互いに押圧して嵌合させる。中脚片１５はこのスライダ１０が開口部２の端部２ａに到達したときにスライダ１０自体が側方に離脱してしまうのを防止するストッパとして機能する。側脚片１１，１１の内側に形成した突起１３，１３はスライダ１０の上方への抜け止めを図っている。   An example of the closing dedicated slider used in the above (1) is shown in FIG. The closing slider 10 includes a pair of side leg pieces 11 and 11 located outside the flap parts 3 and 3 and a middle leg that is located inside the flap parts 3 and 3 and does not reach the zipper 8. And a piece 15. When the slider 10 slides in either direction, the protrusions 12 and 12 formed inside the side leg pieces 11 and 11 press the protrusions and recesses 8a and 8b of the zipper 8 together. The middle leg piece 15 functions as a stopper that prevents the slider 10 itself from detaching laterally when the slider 10 reaches the end 2a of the opening 2. The protrusions 13 and 13 formed inside the side leg pieces 11 and 11 prevent the slider 10 from coming off upward.

ところで、この種の閉止専用スライダ１０にあっては、袋１の開口部２から矢印Ｙ方向に外れないように構成されてはいるが、ある程度の力が作用すると外れてしまう。この場合、スライダ１０を開口部２に装着し直すことは極めて困難である。即ち、中脚片１５をフラップ部３，３の内側に挿入する必要があるが、フラップ部３，３は側脚片１１，１１で押さえられるため、専用の治具を用いることなく手で挿入することは実質上無理である。   By the way, this kind of closing-only slider 10 is configured so as not to be detached from the opening 2 of the bag 1 in the direction of the arrow Y, but will come off when a certain amount of force is applied. In this case, it is extremely difficult to reattach the slider 10 to the opening 2. That is, it is necessary to insert the middle leg piece 15 inside the flap portions 3 and 3, but the flap portions 3 and 3 are pressed by the side leg pieces 11 and 11, so that they are inserted by hand without using a dedicated jig. It is virtually impossible to do.

また、閉止を開始する際に、開口端部２ａにセットされているスライダ１０をスムーズにスライドさせるには、端部２ａを指でつまんで押さえればよい。しかし、袋１が溶断袋であると端部２ａに指でつまめる余裕がなく、閉止動作の開始がやっかいである。   In order to smoothly slide the slider 10 set on the opening end 2a when starting the closing, the end 2a may be pinched with a finger and pressed. However, if the bag 1 is a fusing bag, there is no room to pinch the end 2a with a finger, which makes it difficult to start the closing operation.

そこで、本発明の目的は、樹脂フィルム製袋の開口部から外れた場合であっても容易に再装着可能な閉止専用スライダを提供することにある。 An object of the present invention is that even when out of the opening of the tree fat film bag to provide easily re wearable closure dedicated slider.

本発明の他の目的は、前記目的を達成すると共に、ジッパーの閉止動作をスムーズに開始することのできる閉止専用スライダを提供することにある。 Another object of the present invention is to achieve the above object, it is to provide a closure dedicated slider which can initiate a closing operation of the zipper smoothly.

以下、本発明に係る閉止専用スライダの実施形態について、添付図面を参照して説明する。 Hereinafter, embodiments of the closure dedicated slider according to the present invention will be described with reference to the accompanying drawings.

（第１実施形態、図１〜図３参照）
図１、図２は本発明の第１実施形態である閉止専用スライダ３０Ａを示す。このスライダ３０Ａは基本的には図１０に示した従来の閉止専用スライダ１０と同様の構成を有し、図９に示した樹脂フィルム製袋１の開口部２に設けたジッパー８を閉止する機能を有し、さらに、開口部２から外れた場合に容易に再装着できる機能を付加したものである。 (Refer 1st Embodiment and FIGS. 1-3)
1 and 2 show a closing dedicated slider 30A according to the first embodiment of the present invention. This slider 30A basically has the same structure as the conventional closing dedicated slider 10 shown in FIG. 10, and has a function of closing the zipper 8 provided in the opening 2 of the resin film bag 1 shown in FIG. In addition, a function that can be easily remounted when it is detached from the opening 2 is added.

詳しくは、このスライダ３０Ａは、樹脂フィルム製袋１のフラップ部３，３の外側に位置する一対の側脚片３１，３１と、フラップ部３，３の内側に位置してジッパー８には届かない長さの中脚片３５とを備えている。スライダ３０Ａはいずれかの方向にスライドすることにより、側脚片１１，１１の内側に形成した凸部３２，３２がジッパー８の凹凸部８ａ，８ｂを互いに押圧して嵌合させる。中脚片３５はスライダ３０Ａが開口部２の一端部２ａに到達したときにスライダ３０Ａ自体が側方に離脱してしまうのを防止するストッパとして機能する。側脚片３１，３１の内側に形成した突起３３，３３はスライダ３０Ａが開口部２から上方へ抜けることを防止するためのものである。また、突起３４，３４はスライダ３０Ａが必要以上に下方へ移動することを防止するためのものである。   Specifically, the slider 30A is positioned on the outside of the flap portions 3 and 3 of the plastic film bag 1 and on the inside of the flap portions 3 and 3 and reaches the zipper 8. The middle leg piece 35 is not long. By sliding the slider 30A in either direction, the convex portions 32, 32 formed inside the side leg pieces 11, 11 press the concave and convex portions 8a, 8b of the zipper 8 together to fit. The middle leg piece 35 functions as a stopper that prevents the slider 30A itself from being detached laterally when the slider 30A reaches the one end 2a of the opening 2. The protrusions 33 and 33 formed on the inner side of the side leg pieces 31 and 31 are for preventing the slider 30 </ b> A from slipping upward from the opening 2. Further, the protrusions 34 and 34 are for preventing the slider 30A from moving downward more than necessary.

このスライダ３０Ａにおいて、側脚片３１，３１の一側部根元部分には三角形状の切欠き３１ａ，３１ａが形成されており、中脚片３５の一側部根元部分がこの切欠き３１ａ，３１ａから露出している。符号３５ａはこの露出部分を示す。   In the slider 30A, triangular cutouts 31a and 31a are formed in one side root portions of the side leg pieces 31 and 31, and one side root portions of the middle leg piece 35 are formed in the cutouts 31a and 31a. Is exposed from. Reference numeral 35a indicates the exposed portion.

このように中脚片３５の側部に露出部分３５ａを設けたのは、スライダ３０Ａに強い外力が作用して袋１の開口部２から外れた場合（外れる方向は図９に示す矢印Ｙ参照）、再装着を容易にするためのである。即ち、図３（Ａ）に示すように、まず、スライダ３０Ａを斜めに傾けた状態で、中脚片３５の露出部分３５ａをフラップ部３，３の間に挿入する。そして、図３（Ｂ）に示すように、スライダ３０Ａを水平状態に回転させる。これにて、側脚片３１，３１がフラップ部３，３の外側に位置すると共に、中脚片３５が先端部分までフラップ部３，３の間に挿入される。さらに、図３（Ｃ）に示すように、スライダ３０Ａを直立状態まで回転させる。これにて、いわばワンタッチでスライダ３０Ａが袋１の開口部２に取り付けられたことになる。   The exposed portion 35a is provided on the side of the middle leg piece 35 as described above when a strong external force acts on the slider 30A to disengage from the opening 2 of the bag 1 (see the arrow Y shown in FIG. 9 for the direction of removal). ), To facilitate remounting. That is, as shown in FIG. 3A, first, the exposed portion 35a of the middle leg piece 35 is inserted between the flap portions 3 and 3 with the slider 30A inclined obliquely. Then, as shown in FIG. 3B, the slider 30A is rotated horizontally. Thus, the side leg pieces 31 and 31 are positioned outside the flap portions 3 and 3, and the middle leg piece 35 is inserted between the flap portions 3 and 3 up to the tip portion. Further, as shown in FIG. 3C, the slider 30A is rotated to the upright state. Thus, the slider 30A is attached to the opening 2 of the bag 1 with one touch.

このような再装着をより一層容易にするために、図２（Ｄ）に示すように、突起３３，３４の一端部３３ａ，３４ａは削り取られている。   In order to make such remounting easier, as shown in FIG. 2 (D), the one end portions 33a, 34a of the protrusions 33, 34 are scraped off.

なお、図３で斜線を付した部分は袋１の側部溶着部分である。図８の斜線を付した部分も同様に側部溶着部分である。   Note that the hatched portion in FIG. 3 is the side welded portion of the bag 1. The hatched portion in FIG. 8 is also a side welded portion.

また、この第１実施形態であるスライダ３０Ａにおいて、前記切欠き３１ａは必ずしも三角形状である必要はなく、図１（Ａ）に一点鎖線で示すような形状であってもよい。このような形状の切欠きを設けたスライダは、第１実施形態と以下に示す第２実施形態の中間形態であるともいえる。   In the slider 30A according to the first embodiment, the notch 31a does not necessarily have a triangular shape, and may have a shape as indicated by a one-dot chain line in FIG. It can be said that the slider provided with such a cutout is an intermediate form between the first embodiment and the second embodiment described below.

（第２実施形態、図４参照）
図４は本発明の第２実施形態である閉止専用スライダ３０Ｂを示す。このスライダ３０Ｂは前記第１実施形態として示したスライダ３０Ａと基本的には同じ構成からなり、図１、図２と同じ部分には同じ符号を付し、重複した説明は省略する。 (See the second embodiment, FIG. 4)
Figure 4 shows a second embodiment which is closed only slider 30B of the present invention. The slider 30B basically has the same configuration as the slider 30A shown as the first embodiment, and the same parts as those in FIGS. 1 and 2 are denoted by the same reference numerals, and redundant description is omitted.

スライダ３０Ｂにおいて、前記スライダ３０Ａと異なるのは、スライダ３０Ｂの上部から一側部にわたって中脚片３５と側脚片３１，３１とでフラップ部３，３を挟み込む一対のスリット３６，３６を形成した点にある。   The slider 30B differs from the slider 30A in that a pair of slits 36 and 36 are formed to sandwich the flap portions 3 and 3 between the middle leg piece 35 and the side leg pieces 31 and 31 from one side to the upper side of the slider 30B. In the point.

このスライダ３０Ｂにあっては、樹脂フィルム製袋１の開口部２から外れた場合であっても、図３に示したのと基本的には同じ手順で再装着することができる。即ち、開口部２の斜め上方からスリット３６，３６にフラップ部３，３を挿入させると、中脚片３５がフラップ部３，３の間に挿入された状態でフラップ部３，３を中脚片３５と側脚片３１，３１とでいわば挟み込んだ状態となる。その後、スライダ３０Ｂをほぼ９０°強回転させることで、容易に再装着することができる。   In the slider 30B, even when the slider 30B is detached from the opening 2 of the resin film bag 1, the slider 30B can be remounted by the same procedure as shown in FIG. That is, when the flaps 3 and 3 are inserted into the slits 36 and 36 from obliquely above the opening 2, the flaps 3 and 3 are placed in the state where the middle leg piece 35 is inserted between the flaps 3 and 3. In other words, the piece 35 and the side leg pieces 31, 31 are sandwiched. After that, the slider 30B can be easily remounted by rotating the slider 30B slightly over 90 °.

（第３実施形態、図５参照）
図５は本発明の第３実施形態である閉止専用スライダ３０Ｃを示す。このスライダ３０Ｃは前記第１実施形態として示したスライダ３０Ａと基本的には同じ構成からなり、図１、図２と同じ部分には同じ符号を付し、重複した説明は省略する。 (Refer to the third embodiment, FIG. 5)
Figure 5 shows a third embodiment which is closed only slider 30C of the present invention. The slider 30C basically has the same configuration as the slider 30A shown as the first embodiment, and the same parts as those in FIGS. 1 and 2 are denoted by the same reference numerals, and redundant description is omitted.

スライダ３０Ｃにおいて前記スライダ３０Ａと異なるのは、中脚片３５に突出片部３５ｂを形成して側脚片３１，３１より側方に露出させた点にある。この突出片部３５ｂが前記スライダ３０Ａの露出部分３５ａと同様の機能を発揮し、スライダ３０Ｂを袋１の開口部２へ再装着するのを容易にしている。   The slider 30C is different from the slider 30A in that a protruding piece portion 35b is formed on the middle leg piece 35 and is exposed laterally from the side leg pieces 31 and 31. The protruding piece 35b exhibits the same function as the exposed portion 35a of the slider 30A, and makes it easy to reattach the slider 30B to the opening 2 of the bag 1.

（第４実施形態、図６参照）
図６は本発明の第４実施形態である閉止専用スライダ３０Ｄを示す。このスライダ３０Ｄは前記第１実施形態として示したスライダ３０Ａと基本的には同じ構成からなり、図１、図２と同じ部分には同じ符号を付し、重複した説明は省略する。 (See the fourth embodiment, FIG. 6)
FIG. 6 shows a closing dedicated slider 30D according to the fourth embodiment of the present invention. The slider 30D basically has the same configuration as the slider 30A shown as the first embodiment, and the same parts as those in FIGS. 1 and 2 are denoted by the same reference numerals and redundant description is omitted.

スライダ３０Ｄにおいて前記スライダ３０Ａと異なるのは、側脚片３１，３１の両側部分に比較的大きな切欠き３１ｃ，３１ｃを形成し、中脚片３５の両側部を露出させた点にある。符号３５ｃはこの露出部分を示す。このスライダ３０Ｄにあっては、露出部分３５ｃをフラップ部３，３の間にほぼ直交した状態で上方から挿入して袋１の開口部２へ再装着する。   The slider 30D is different from the slider 30A in that relatively large notches 31c and 31c are formed on both side portions of the side leg pieces 31 and 31, and both side portions of the middle leg piece 35 are exposed. Reference numeral 35c indicates the exposed portion. In the slider 30D, the exposed portion 35c is inserted between the flap portions 3 and 3 from the upper side in a substantially orthogonal state, and is reattached to the opening portion 2 of the bag 1.

（第５実施形態、図７、図８参照）
図７は本発明の第５実施形態である閉止専用スライダ３０Ｅを示す。このスライダ３０Ｅは前記第１実施形態として示したスライダ３０Ａと基本的には同じ構成からなり、図１、図２と同じ部分には同じ符号を付し、重複した説明は省略する。 (Refer to the fifth embodiment, FIG. 7 and FIG. 8)
FIG. 7 shows a closing dedicated slider 30E according to the fifth embodiment of the present invention. The slider 30E basically has the same configuration as the slider 30A shown as the first embodiment, and the same parts as those in FIGS. 1 and 2 are denoted by the same reference numerals, and redundant description is omitted.

スライダ３０Ｅにおいて前記スライダ３０Ａと異なるのは、側脚片３１，３１の両側部分に切欠き３１ｄ，３１ｄを形成すると共に、中脚片３５に突出片部３５ｄ，３５ｄを形成した点にある。この突出片部３５ｄ，３５ｄの露出面積は前記スライダ３０Ａ，３０Ｃ，３０Ｄよりも比較的大きい。   The slider 30E differs from the slider 30A in that notches 31d and 31d are formed on both side portions of the side leg pieces 31 and 31, and projecting pieces 35d and 35d are formed on the middle leg piece 35. The exposed areas of the protruding pieces 35d and 35d are relatively larger than those of the sliders 30A, 30C and 30D.

突出片部３５ｄは前記スライダ３０Ａの露出部分３５ａと同様の機能を発揮し、スライダ３０Ｅを袋１の開口部２へ再装着するのを容易にしている。さらに、突出片部３５ｄは、図８に示すように、スライダ３０Ｅを開口部２の端部２ａに位置させてジッパー８を閉止する動作を開始する際、一方の手の指で突出片部３５ｄをフラップ部３，３の外側からつまみ、他方の手の指でスライダ３０Ｅをつまんで矢印ａ方向にスライドさせることにより、閉止動作をスムーズに開始させることができる。   The protruding piece 35d exhibits the same function as the exposed portion 35a of the slider 30A, and makes it easy to reattach the slider 30E to the opening 2 of the bag 1. Further, as shown in FIG. 8, the protruding piece 35 d is located at the end 2 a of the opening 2 and starts the operation of closing the zipper 8. Is gripped from the outside of the flap portions 3 and 3, and the slider 30E is pinched with the finger of the other hand and slid in the direction of the arrow a, so that the closing operation can be started smoothly.

溶断袋１にあっては、端部２ａに指でつまむ余裕がないのであるが、このスライダ３０Ｅでは比較的面積の大きな突出片部３５ｄを設けることで、つまみ代を設けることができた。   In the fusing bag 1, the end portion 2a cannot be pinched with a finger, but the slider 30E can be provided with a knob allowance by providing a protruding piece portion 35d having a relatively large area.

なお、本発明に係る閉止専用スライダは、前記実施形態に限定するものではなく、その要旨の範囲内で種々に変更できることは勿論である。 Incidentally, closed dedicated slider according to the present invention is not the limited to the embodiment, it is of course possible change in various ways within the scope of the invention.

また、ジッパー付き樹脂フィルム製袋としては、原反の樹脂フィルムにジッパーを溶着して製袋したものの他、ジッパーが一体化されている樹脂フィルムを使用して製袋したものであってもよい。さらに、ジッパーは対向する凹凸部を２列に設けた、いわゆるダブルジッパー構造であってもよい。   Moreover, as a resin film bag with a zipper, a bag made using a resin film in which a zipper is integrated may be used in addition to a bag made by welding a zipper to an original resin film. . Further, the zipper may have a so-called double zipper structure in which the opposing concave and convex portions are provided in two rows.

以上のように、本発明は、ジッパー付き樹脂フィルム製袋の開口部から外れても容易に再装着することができ、ジッパー付き樹脂フィルム製袋の閉止専用スライダとして有用である。また、本発明は、ジッパーの閉止動作をスムーズに開始させることができ、ジッパー付き樹脂フィルム製袋の閉止専用スライダとして有用である。 As described above, the present invention can be disengaged from the opening of the di-wrapper with a resin film bag can be easily reattached, it is useful as a closing-only slider zipper resin film bag. In addition, the present invention can smoothly start the closing operation of the zipper, and is useful as a dedicated slider for closing the zippered resin film bag.
