【発明の詳細な説明】 DETAILED DESCRIPTION OF THE INVENTION

【0001】 [0001]

【産業上の利用分野】本発明は、袋体の開口部等に設けられる再開閉可能な合成樹脂製チャックに関するものである。 The present invention relates to relates to a re-closable plastic chuck is provided in the opening portion or the like of the bag.

【0002】 [0002]

【従来の技術】袋体の開口部に互いに咬合する雌雄爪よりなる再開閉機能を持った合成樹脂製チャックは図3で示すように、一方のベース片1aに鈎部を先端に形成した雄爪要素2と、他方のベース片1bに前記雄要素2の鈎部に咬合する鈎部を形成した雌要素3とから構成されたシングル爪チャックと、このシングル爪チャックよりも咬合強度を増大して重袋に対応するよう、図4で示すように、2本の雄爪要素2a、2bを並列したダブル爪チャックとが公知である。 BACKGROUND ART Synthetic resin chuck having a re-closing functionality consisting sex pawl bite each other in the opening of the bag as shown in Figure 3, the male formed at the tip of the hook portion on one of the base piece 1a a pawl element 2, increases and a single jaw chuck constructed from female element 3 which is formed a hook portion which bite into the hook portion of the to the other base piece 1b male element 2, the occlusal strength than the single jaw chuck to accommodate Te heavy bag, as shown in Figure 4, the two male claw element 2a, and a double-jaw chuck in parallel and 2b are known.

【0003】 [0003]

【発明が解決しようとする課題】しかし、どのような爪型のチヤック付袋体であっても、袋体に包入されている物品が嵩さばっていたり或いは重量物や流動物であった場合には、袋体の膨らみにより図4で示すように引張力Fがチャックに作用し、雌爪要素3の袋体内側方の一方の鈎部は開き方向に伸び、これと咬合する一方の雄爪要素2aは咬合から外れる方向に傾倒し、また、袋体外側方の他方の雌爪要素3の鈎部と雄爪要素2bの鈎部とは咬合が外れた遊離状態となり自然開脱する。 [SUMMARY OF THE INVENTION] However, whatever be the chucking with bag of nails type, the article being encased in a bag body was bulky and aeration have or alternatively heavy and fluids in this case, the bulge of the bag acts on the tensile force F is chuck as shown in Figure 4, one of the hook portion of the bag body internal side of Mesutsume element 3 extends in the opening direction, one of the occlusal and this male claw element 2a is tilted in a direction deviating from the occlusal, also, the hook portion of the hook portion and the male claw elements 2b of the other Mesutsume element 3 of the bag outward naturally Hirakida' becomes free state occlusion is out .

【0004】このような自然開脱は、袋体を重ね積みした場合の重圧或いは輸送時おける揺動圧等によって包入物品が揺動し、その動圧により咬合状態のチャックが内側から開脱してしまうことがある。 [0004] Such natural Hirakida' is wrapped incoming article is swung by pressure or definitive during transportation oscillating pressure and the like in the case of stacked superposed bag, emerged open chuck occlusion from the inside by the dynamic pressure it may become. 従って、従来のチャック付袋体においては、重包装を避けることが常識とされていた。 Therefore, in the conventional chuck with bag, to avoid heavy packaging has been common knowledge.

【0005】例えば、米をチャック付袋体に包入した場合は、チャックを閉じると共に、チャック上部の摘み開口部をヒートシールした後、袋体を積み上げたり輸送したりすると、積み上げ時には重圧により、また、輸送時は揺動圧によって米が動くので、それらの動圧がチャックに影響して開脱してしまう。 [0005] For example, if you encased rice bag body with zipper, closes the chuck, after heat-sealing the knob opening of the chuck top and or or transporting piled up bag by pressure at the time of stacking, also, during transportation because rice is moved by the swinging pressure, their dynamic pressure will be out opening affecting the chuck.

【0006】チャックが開脱しても、チャック上部の摘み片部はシールされているので、直ちに米が洩れ出すことはないが、鋏等でシールを切り取った時にはチャックが開脱しているため、米が飛散するようなことがある。 [0006] also be out chuck is open, because the knob piece of chuck top is sealed, but it is not immediately leaking the US, because it has emerged chuck is open when you cut the seal with scissors, US there may as scatter.

【0007】また、開封後のチャックを閉じた場合も、 [0007] In addition, even if you close the chuck after opening,
袋体が横倒しになった時には米の流動によってチャックが内部方向から開脱し、米が袋外に飛散したりすることがあり、米の包装袋としては不向きであった。 Emerged open chuck from the inside direction by the flow of rice when the bag is turned sideways, rice may or scattered outside the bag, was not suitable as a rice packaging bag.

【0008】上記のような問題を解決するために、チャック自体の肉厚を大にしたチャックとの袋体も考えてはいる。 [0008] In order to solve the problems as described above, is is also thought the bag body of the chuck, which was large the thickness of the chuck itself. しかし、構成樹脂による咬合型のチャックは肉厚が大になるほど樹脂の性質上で爪が硬くなり咬合強度も強くなるので、指先押圧による咬合の場合は指先が痛くなったり、指先の引張りによる開脱の場合は指先が滑ったりする等の不具合がある。 However, since the wall thickness of the occlusal type of chuck by the configuration resin nails also become stronger harder will bite strength on the nature of the resin enough to become large, or fingertip becomes painful in the case of occlusion by the fingertip pressing, open by pulling the fingertip in the case of prolapse there is a problem such as the slipping fingertips.

【0009】また、肉厚大のチャックを製造する場合には樹脂量も多くなるので、ダイスからの押しだし速度の低下を招くと共に、冷却に時間を要する等の生産効率が悪くコスト高となる。 Further, since many amount of resin in the production of chuck meat Atsudai, with deteriorated push out speed from the die, production efficiency, such as time-consuming for cooling becomes deteriorated cost.

【0010】一般的に、チャック付の袋体は、そのサイズを小さくするほどチャックの摘み片の幅を小さくさせざるを得ないので、このような小サイズの袋体に肉厚大で剛性のあるチャックを設けた場合は指先による開脱が一層困難となってしまう。 [0010] Generally, the bag body equipped with the chuck, because inevitably to reduce the width of chucking the tab of the smaller its size, wall thickness sized rigid bag of such small size some case in which the chuck is open leaving by fingertip becomes more difficult.

【0011】そこで、上述の図4で示すダブル爪チャックを採用しても上記のような不具合があり、これらの問題を解決することが課題となっている。 [0011] Therefore, there is the above-described problem also adopted the double-jaw chuck shown in Figure 4 above, it is to solve these problems is a challenge.

【0012】本発明の目的は、上記の課題を解決した合成樹脂製チャックを提供することである。 An object of the present invention is to provide a synthetic resin chuck wherein the foregoing problems are eliminated.

【0013】 [0013]
