Description

本発明は、袋の開口部に設けられている雌雄咬合型チャックの咬合を容易且つ確実にした合成樹脂製チャック付の袋体に関するものである。   The present invention relates to a bag body with a synthetic resin chuck that can easily and reliably bite a male and female bite type chuck provided in an opening of a bag.

図５で例示するように表裏の胴部フィルム２ａ、２ｂよりなる合成樹脂製包装袋において、その開口部３の内側に雌雄咬合型のチャック５が設けられた合成樹脂製チャック付の袋体１（以下袋体という）は周知である。この袋体において、チャック５を咬合して開口部３を閉じるには、チャック５の背面を指腹部で挟圧しチャック５の長手方向にスライドする操作が一般的である。 As illustrated in FIG. 5 , in a synthetic resin packaging bag made of front and back body film 2 a, 2 b, a bag 1 with a synthetic resin chuck in which a male and female bite type chuck 5 is provided inside the opening 3. (Hereinafter referred to as a bag) is well known. In this bag body, in order to occlude the chuck 5 and close the opening 3, an operation of pressing the back surface of the chuck 5 with the finger pad and sliding it in the longitudinal direction of the chuck 5 is generally performed.

しかし、チャック５の全幅に渡って指腹部でチャック５の背面を挟圧して指腹部を背面ラインに沿ってスライドする際に、例えば、手が水で濡れて滑り易い場合、指腹部がチャック５の背面ラインから逸脱してチャック５の咬合が不完全となる。この場合は指腹部がチャック５の背面ラインから逸脱した近辺のチャック５の背面位置を指腹部で再度挟圧してスライド操作をしている。   However, when the finger pad is squeezed with the finger pad over the entire width of the chuck 5 and the finger pad is slid along the back line, for example, when the hand is wet and easily slips, the finger pad is the chuck 5. Deviating from the back line of the chuck 5, the occlusion of the chuck 5 becomes incomplete. In this case, the sliding operation is performed by pinching the back position of the chuck 5 in the vicinity where the finger pad part deviates from the back line of the chuck 5 with the finger pad part again.

また、指腹部がチャック５の背面ラインから逸脱しないが、逸脱しそうになった場合は指腹部の位置をチャック５の背面に補正しながら、いわゆる蛇行を繰り返してチャック５を咬合している。   In addition, the finger pad does not deviate from the back line of the chuck 5, but when it is about to deviate, the chuck 5 is engaged by repeating so-called meandering while correcting the position of the finger pad to the back of the chuck 5.

このように従来の合成樹脂製チャック付の袋体においては、いわゆるチャック掛けに問題があり、この問題はチャック５の全幅が長く、腰が弱い薄手の表裏の胴部フィルム２ａ、２ｂによる袋体において顕著であり、チャック掛けが容易且つ確実に行うようにすることが課題となっていた。
特開平４−１５４５５８公報 特開平６−１２２４６０公報 As described above, the conventional bag body with a synthetic resin chuck has a problem of so-called chucking, and this problem is caused by the thin body films 2a and 2b on the front and back of the thin chuck 5 having a long overall width and weak waist. In this case, it has been a problem to make the chucking easily and reliably.

When the back surface of the chuck is clamped by the finger pad, the depression for entering the finger pad generated in the space between the chuck and the weir band is directed from the weir band side to the chuck side. A bag body with a synthetic resin chuck characterized by having a downward slope.

本発明によると、チャックの背面を指先で挟圧した指腹部はチャックと平行に設けた堰状帯によってチャックの背面ラインから逸脱することを阻止しチャックの背面ラインに沿って案内規制されてスライドするため、いわゆるチャック掛けを容易且つ確実にした効果を有している。   According to the present invention, the finger pad portion that presses the back surface of the chuck with the fingertip is prevented from deviating from the back surface line of the chuck by the weir-like band provided in parallel with the chuck, and is guided and regulated along the back surface line of the chuck. Therefore, there is an effect that the so-called chucking is easily and reliably performed.

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。袋体を横向きにした状態の要部断面図である図１において、１は合成樹脂製チャック付の袋体（以下袋体という）である。この袋体１は合成樹脂製の雌雄咬合型チャック５が表裏の胴部フィルム２ａ、２ｂよりなる合成樹脂製包装袋の開口部３の内側に対面して設けられている。尚、符号の４は袋内側を示す。   The best mode for carrying out the present invention will be described below with reference to the drawings. In FIG. 1, which is a cross-sectional view of the main part in a state where the bag body is turned sideways, 1 is a bag body (hereinafter referred to as a bag body) with a synthetic resin chuck. In this bag body 1, a male / female occlusal chuck 5 made of synthetic resin is provided so as to face the inside of an opening 3 of a synthetic resin packaging bag made of front and back body films 2 a and 2 b. Reference numeral 4 indicates the inside of the bag.

本発明は上記の袋体１において、前記チャック５の背面を指腹部で挟圧しチャック５の長手方向にスライドしてチャック５を咬合する際に、前記指腹部をチャック５の背面ラインから逸脱することを阻止しチャック５の背面ラインに沿って案内規制する堰状帯をチャック５の近傍にチャック５と平行に設けたことを特徴とするものである。   According to the present invention, when the back surface of the chuck 5 is clamped by the finger pad portion and slid in the longitudinal direction of the chuck 5 to engage the chuck 5, the finger pad portion deviates from the back line of the chuck 5. This is characterized in that a weir-like band that prevents this and guides and regulates along the back line of the chuck 5 is provided in the vicinity of the chuck 5 in parallel with the chuck 5.

上記チャック５の背面を指腹部で挟圧しチャック５の長手方向にスライドしてチャック５を咬合する際に、前記指腹部をチャック５の背面ラインから逸脱することを阻止しチャック５の背面ラインに沿って案内規制する堰状帯をチャック５と平行に設けた具体的な実施例を説明する。図１で示すように、表裏の胴部フィルム２ａ、２ｂの内側面にチャック５を中央にして開口部３側と袋内側４に堰状帯６ａ、６ｂ、７ａ、７ｂを対面して設けた構造である。   When the back surface of the chuck 5 is clamped by the finger pad portion and slid in the longitudinal direction of the chuck 5 to engage the chuck 5, the finger pad portion is prevented from deviating from the back line of the chuck 5, and the back surface line of the chuck 5 is prevented. A specific embodiment in which a dam-like band for guiding and regulating along the chuck 5 is provided in parallel with the chuck 5 will be described. As shown in FIG. 1, weirs 6a, 6b, 7a and 7b are provided facing the opening 3 side and the bag inner side 4 on the inner surfaces of the front and back body films 2a and 2b with the chuck 5 in the center. Structure.

上記堰状帯６ａ、６ｂ、７ａ、７ｂはチャック５の中心から６〜８ｍ／ｍ前後離間した位置に設けることが望ましい。また、堰状帯６ａ、６ｂ、７ａ、７ｂの断面形状は、チャック５の背面を挟圧した指腹部がチャック５の背面ラインからの逸脱を堰状帯６ａ、６ｂ、７ａ、７ｂで制止することが目的であるため、正方形、長方形、台形等が適当である。そして、この断面の面積は１〜２ｍｍ２前後が望ましい。さらに、対接した堰状帯６ａ、６ｂ、７ａ、７ｂの厚味は咬合したチャック５の厚味相当が適当である。 The weir-like bands 6a, 6b, 7a, 7b are preferably provided at positions separated from the center of the chuck 5 by about 6-8 m / m. Further, the cross-sectional shapes of the dam-like bands 6a, 6b, 7a, 7b are such that the finger pad portion sandwiching the back surface of the chuck 5 prevents the deviation from the back line of the chuck 5 by the dam-like bands 6a, 6b, 7a, 7b. since it is an object, square, rectangular, trapezoidal shape or the like are suitable. The area of this cross section is preferably about 1 to 2 mm2. Further, the thickness of the weir strips 6a, 6b, 7a, 7b that are in contact with each other is suitably equivalent to the thickness of the chuck 5 that is engaged.

上記の構造よりなる本発明の作用効果について、図５に示された従来例と対比しつつ、図２〜図４によって説明する。図５に示すように、従来、開口部３のチャック５を閉じる（咬合）ために、例えば、人差し指と親指の指腹部でチャック５の背面を挟圧しながらチャック５の雌雄爪を咬合させチャック５の長手方向に指腹部をチャック５と平行移動しながら連続的にスライドする必要がある。しかしながら、従来タイプの袋では、チャック５の背面に沿って指腹部をスライドさせても、咬合したチャック５の凸状構造と表裏の胴部フィルム２ａ、２ｂ表面のスリップ性のため、指腹部がチャック５の背面を上下方向に蛇行したり脱線したりして、チャック掛けをスムーズに行うことが難しかった。 The operational effects of the present invention having the above structure will be described with reference to FIGS . 2 to 4 in comparison with the conventional example shown in FIG. As shown in FIG. 5 , conventionally, in order to close (engage) the chuck 5 of the opening 3, for example, the male and female claws of the chuck 5 are engaged with each other while the back surface of the chuck 5 is pressed between the index finger and the finger pad of the thumb. It is necessary to slide the finger pad part continuously in parallel with the chuck 5 in the longitudinal direction. However, in the conventional type bag, even if the finger pad portion is slid along the back surface of the chuck 5, the finger pad portion does not move due to the convex structure of the chuck 5 and the slip properties of the front and back body films 2a and 2b. It was difficult to smoothly chuck the chuck 5 by meandering or derailing the back surface of the chuck 5 in the vertical direction.

そこで、この従来の問題を解決するため、本発明は、チャック５を中央にして上下に堰状帯６ａ、６ｂ、７ａ、７ｂを設けた。図３に示されるように、指先が小さく細いタイプの手では、チャック５の背面を人差し指と親指の指腹部で挟圧すると、指腹部はチャック５と堰状帯６ａ、６ｂ、７ａ、７ｂの全体を押圧することが困難である。この状態において指腹部をチャック５と平行移動する過程で指が上方に逃げた場合はチャック５と堰状帯６ａ、６ｂとの間の窪み８に入り込み、窪み８に入り込んだ指腹部はチャック５と堰状帯６ａ、６ｂに挟まれたままチャック５と平行移動してスライドすることになる。また、これとは逆に指が下方に逃げた場合も同様で指腹部が下方の窪み９に入り込みチャック５と堰状帯７ａ、７ｂに挟まれたままチャック５と平行移動してスライドする。すなわち、指腹部はチャック５の背面ラインから上方または下方に逸脱しようとしても堰状帯６ａ、６ｂ、７ａ、７ｂで阻止され、その結果、指腹部は窪み８または９によって案内規制され、チャック５の背面ラインに沿ってスライドしてチャック掛け（咬合）を容易かつ確実に行うことができる。   Therefore, in order to solve this conventional problem, in the present invention, weir-like bands 6a, 6b, 7a, and 7b are provided above and below the chuck 5 as the center. As shown in FIG. 3, in a hand with a small and thin fingertip, when the back surface of the chuck 5 is clamped between the index finger and the finger pad portion of the thumb, the finger pad portion of the chuck 5 and the dam-like bands 6a, 6b, 7a, 7b It is difficult to press the whole. In this state, when the finger escapes upward in the process of moving the finger pad part in parallel with the chuck 5, the finger pad part enters the recess 8 between the chuck 5 and the dam-like bands 6a, 6b. And slide in parallel with the chuck 5 while being sandwiched between the weir-like bands 6a and 6b. Conversely, when the finger escapes downward, the finger pad portion enters the lower recess 9 and slides while moving parallel to the chuck 5 while being sandwiched between the chuck 5 and the weir-like bands 7a and 7b. That is, the finger pad portion is blocked by the dam-like bands 6a, 6b, 7a, 7b even if it deviates upward or downward from the back line of the chuck 5. As a result, the finger pad portion is guided and restricted by the recess 8 or 9, and the chuck 5 It is possible to easily and reliably perform chucking (occlusion) by sliding along the back surface line.

指先が大きな太いタイプの手では図４で示すように、チャック５の背面を指腹部で挟圧することによりチャック５を中央にしてチャック５と堰状帯６ａ、６ｂ、７ａ、７ｂとの間に窪み８、９ができてチャック５の背面を挟圧した指腹部の一部が窪み８、９に入り込むと共に、指腹部の他の一部が堰状帯６ａ、６ｂ、７ａ、７ｂを押さえる形となり、窪み８、９に入り込んだ指腹部の一部はチャック５と堰状帯６ａ、６ｂ、７ａ、７ｂとで挟まれて案内規制され、より一層に安定した状態で堰状帯６ａ、６ｂ、７ａ、７ｂによりチャック５の背面ラインからの逸脱を阻止し、チャック５の背面ラインに沿ってスライドしてチャック掛け（咬合）する。   As shown in FIG. 4, in a thick type hand with a large fingertip, the back surface of the chuck 5 is clamped by the finger pad portion so that the chuck 5 is in the center and between the chuck 5 and the weir-like bands 6a, 6b, 7a, 7b. A part of the finger pad part where the recesses 8 and 9 are formed and the back surface of the chuck 5 is clamped enters the recesses 8 and 9, and the other part of the finger pad part presses the dam-like bands 6a, 6b, 7a and 7b. Then, a part of the finger pad portion that has entered the recesses 8 and 9 is sandwiched between the chuck 5 and the dam-like bands 6a, 6b, 7a, and 7b and is guided and regulated, and the dam-like bands 6a and 6b are further stabilized. , 7a and 7b prevent deviation from the back line of the chuck 5, and slide along the back line of the chuck 5 to engage (chuck) the chuck.

上記の実施例は、表裏の胴部フィルム２ａ、２ｂの内側面にチャック５を中央にして開口部３側と袋内側４に堰状帯６ａ、６ｂ、７ａ、７ｂを対面して設けた構造である。   In the above embodiment, the inner surface of the front and back body film 2a, 2b is provided with the chuck 5 in the center and the weir-shaped bands 6a, 6b, 7a, 7b facing the opening 3 side and the bag inner side 4 It is.

また、堰状帯６ａ、６ｂ、７ａ、７ｂは単独で表裏の胴部フィルム２ａ、２ｂに熱溶着してもよいし、あるいはチャックテープ上あるいは別途テープ上に設けてもよい。   Further, the dam-like bands 6a, 6b, 7a, 7b may be thermally welded to the front and back body films 2a, 2b alone, or may be provided on the chuck tape or on a separate tape.

このように本発明は、チャック５の背面を指先で挟圧した指腹部はチャック５と平行に設けた堰状帯によってチャック５の背面ラインから逸脱することを阻止しチャック５の背面ラインに沿って案内規制されてスライドするため、チャック掛け（咬合）を容易且つ確実に行うことができ、従来の問題を解消した利点を有している。   As described above, according to the present invention, the finger pad portion sandwiching the back surface of the chuck 5 with the fingertips is prevented from deviating from the back surface line of the chuck 5 by the weir-like band provided in parallel with the chuck 5, and along the back surface line of the chuck 5. Therefore, it is possible to easily and surely perform chucking (occlusion), and has an advantage of solving the conventional problems.
