Description

本発明は、袋体の開口部に設けられている再開閉可能な雌雄咬合型のチャックを開閉操作するスライダー付き合成樹脂製袋体に関するものである。   The present invention relates to a synthetic resin bag body with a slider that opens and closes a re-openable / closable male and female occlusion type chuck provided at an opening of the bag body.

表裏２枚の胴部フィルムよりなり左右にサイドシールが施され、開口部にスライダーによって開閉操作する雌雄咬合型のチャックを備えた合成樹脂製袋体は周知である。   A synthetic resin bag body comprising two body film on the front and back, side seals on the left and right sides, and a male and female bite type chuck that is opened and closed by a slider at an opening is well known.

従来のスライダーはチャックを開閉するための内側ガイドがスライダー本体の端面に位置している。そのためチャックの閉じ端においては前記内側ガイドがチャックの雌雄爪間に位置し、チャックを完全に咬合することができず隙間ができ、この隙間により気水密性を損なっている。   In the conventional slider, an inner guide for opening and closing the chuck is located on the end face of the slider body. Therefore, at the closed end of the chuck, the inner guide is positioned between the male and female claws of the chuck, so that the chuck cannot be completely engaged and a gap is formed, and this gap impairs air-water tightness.

また、スライダーの脱落防止のためにスライダー本体の下部にチャックと係合する脱落防止爪を設けたものがあるが、これでは、袋体開閉操作の際の力で脱落防止爪がチャックより係合が外れてスライダーが脱落してしまう場合があった。

本発明によると、スライダーをチャックの閉じ端に移動した時に内側ガイドがチャックの閉じ側のサイドシールに設けた切欠部に没入し、チャツクを押さえて咬合させるための突起部はチャックの閉じ端まで移動するため、チャックは全幅に渡って完全に雌雄咬合するためスライダーのチャック閉じ端において隙間が生ずることがなくなり気水密性を確保する。また、スライダーをチャックの咬合を解除方向に移動することにより内側ガイドのテーパ部及びストレート部によりチャック上方の突条を押し広げてチャックの咬合を解除し、内側ガイドに形成した係合部が突条に常に係合してスライダーの脱落を確実に防止する効果を有している。   According to the present invention, when the slider is moved to the closed end of the chuck, the inner guide is immersed in the notch provided in the side seal on the closing side of the chuck, and the protrusion for holding the chuck and engaging the chuck reaches the closed end of the chuck. Since the chuck moves completely, the chuck is completely engaged with the male and female, so that no gap is formed at the chuck closed end of the slider, thereby ensuring airtightness. In addition, by moving the slider in the release direction of the chuck, the taper and straight part of the inner guide pushes the ridge above the chuck to release the chuck, and the engagement part formed on the inner guide protrudes. It has the effect of reliably engaging the strip and preventing the slider from falling off.

以下本発明を実施するための最良の形態を図面に基づいて説明する。図１はスライダー６がチャツク４の閉じ端に移動した状態を示すものであり、１は裏２枚の胴部フィルムよりなり左右にサイドシールが施された合成樹脂製袋体である。図示のサイドシール２はチャック閉じ端側を示す。袋体の開口部３には図３でも示すように、スライダー６によって開閉操作する雌雄咬合型のチャック４を備えており、このチャック４の上方に対向する一対の突条５をチャック４と平行に設けられている。   The best mode for carrying out the present invention will be described below with reference to the drawings. FIG. 1 shows a state in which the slider 6 has moved to the closed end of the chuck 4. Reference numeral 1 denotes a synthetic resin bag body made of two back body films and side-sealed. The illustrated side seal 2 shows the chuck closed end side. As shown in FIG. 3, the opening 3 of the bag body is provided with a male and female occlusion type chuck 4 that is opened and closed by a slider 6. Is provided.

前記スライダー６には図４にも示されているように、チャック４の咬合を解除するためのテーパ部７ａ及びストレート部７ｂと、前記突条５に係合してスライダー６の脱落を防止する係合部７ｃとを有する内側ガイド７と、前記チャツク４を押さえて咬合させるための突起部８とを備えている。   As shown in FIG. 4, the slider 6 engages with the taper portion 7 a and the straight portion 7 b for releasing the engagement of the chuck 4 and the protrusion 5 to prevent the slider 6 from falling off. An inner guide 7 having an engaging portion 7c and a protruding portion 8 for pressing and engaging the chuck 4 are provided.

さらに、チャック閉じ端側のサイドシール２にはスライダー６をチャック４の閉じ端に移動した時に内側ガイド７が没入する切欠部９が設けられている。図４において符号１０はスライダー本体の下部に形成した脱落防止補助用の爪を示す。   Further, the side seal 2 on the chuck closing end side is provided with a notch 9 into which the inner guide 7 is inserted when the slider 6 is moved to the closing end of the chuck 4. In FIG. 4, reference numeral 10 denotes a drop-out preventing auxiliary claw formed in the lower portion of the slider body.

上記の構造よりなる本発明の作用について説明する。図１は前述の通り、スライダー６がチャック４の閉じ端に移動位置した状態を示し、この状態で内側ガイド７がチャック４の閉じ側のサイドシール２に設けた切欠部９に没入し、チャツク４を押さえて咬合させるための突起部８はチャック４の閉じ端まで移動する。従って、チャック４は全幅に渡って完全に雌雄咬合するためスライダー６のチャック閉じ端において隙間が生ずることがなくなり気水密性を確保する。   The operation of the present invention having the above structure will be described. FIG. 1 shows a state in which the slider 6 is moved to the closed end of the chuck 4 as described above. In this state, the inner guide 7 is inserted into the notch 9 provided in the side seal 2 on the closing side of the chuck 4 to check. The protrusion 8 for pressing and holding the 4 moves to the closed end of the chuck 4. Accordingly, since the chuck 4 is completely engaged with the male and female over the entire width, no gap is formed at the chuck closed end of the slider 6 and air-tightness is ensured.

図１は突起部８がサイドシール２の幅内まで移動した状態となるよう内側ガイド７が切欠部９に没入する切欠部の長さとした実施例であるが、図２で示すように、突起部８がチャック４の閉じ端に位置するよう内側ガイド７が切欠部９に没入する切欠部の長さとしてもスライダー６のチャック閉じ端において隙間が生ずることがなくなり気水密性を確保する。   FIG. 1 shows an embodiment in which the inner guide 7 has a length of a notch that is inserted into the notch 9 so that the protrusion 8 is moved to the width of the side seal 2. As shown in FIG.
