Description

本発明は、袋の内側に折り込まれた底部が押し広がって自立を可能にした包装用袋に関し、その底部の構造を改良して自立安定性を高めた包装用袋に関するものである。   The present invention relates to a packaging bag in which a bottom part folded inside a bag is pushed and spread to enable self-supporting, and relates to a packaging bag having an improved self-supporting stability by improving the structure of the bottom part.

従来、袋の内側に折り込まれた底部が押し広がって自立を可能にした包装用袋として、例えば、特開２００１−７２０８０号公報（特許文献１）、特開２００１−７２０８１号公報（特許文献２）、実開平７−２１５７９号公報（特許文献３）が提供されている。   Conventionally, as packaging bags in which the bottom part folded inside the bag is pushed and spread to enable self-supporting, for example, JP 2001-72080 A (Patent Document 1), JP 2001-72081 A (Patent Document 2). No. 7-21579 (Patent Document 3).

これらは、袋の内側に折り込まれた底部を有していない袋に比べれば、内容物を包入することにより袋の内側に折り込まれた底部が押し広がって自立性を有しているが、内容物を包入することにより底部の中央下方端部が膨らみ、この膨らみにより左右両側の下方端部が内側に引き寄せられ左右両側の下方端部より前記中央下方端部が浮き上がった形態となる。これにより、袋の底部は左右両側の下方端部が接地点となり、これを支点にして袋は前記中央下方端部が浮き上がった隙間分で厚み方向に揺動し、自立性を向上したというものの確実に安定した自立性が得られていない。
特開２００１−７２０８０号公報 特開２００１−７２０８１号公報 実開平７−２１５７９号公報 These are self-supporting because the bottom folded inside the bag is expanded by embedding the contents, compared to a bag that does not have the bottom folded inside the bag, By enclosing the contents, the central lower end portion of the bottom portion swells, and by this bulge, the lower end portions on both the left and right sides are drawn inward, and the central lower end portion is lifted from the lower end portions on both the left and right sides. As a result, the bottom end of the bag is the grounding point at the lower ends on both the left and right sides, and with this as a fulcrum, the bag swings in the thickness direction at the gap where the central lower end is lifted, improving self-sustainability. Certainly stable independence has not been obtained.

The lower part of the center in a state where the bottom part is expanded by the form of the bottom part between the end part and the lower end part on both the left and right sides and the notch part notched above the lower end parts on both the left and right sides. The end portions and the lower end portions on both the left and right sides have an effect of securing a substantially uniform grounding state and improving the self-supporting stability.

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において、１は合成樹脂複層素材乃至合成樹脂を含む各種複層素材よりなる包装用袋を示す。この包装用袋１の底部８は、当該袋１の内側に折り込まれたガゼット２が船底形状シール３とサイドシール４とによって拡開可能に設けられる。従って、底部８の下方端部はその所要部が接着されて剛性が付与されている。 The best mode for carrying out the present invention will be described below with reference to the drawings. In FIG. 1 , 1 shows the packaging bag which consists of various multilayer material containing synthetic resin multilayer material thru | or synthetic resin . Bottom 8 of the packaging bag 1, Gazette 2 folded inwardly of the bag 1 is Ru provided so as to be expanded by a ship bottom shape seal 3 and the side seal 4. Accordingly, the lower end portion of the bottom portion 8 is provided with rigidity by bonding a required portion thereof.

前記底部８は左右両側の下方端部５ｂに比し中央の下方端部５ａを長くして左右両側の下方端部５ｂと中央の下方端部５ａとは段差６を形成している。この段差６は包装用袋１の大小、底部8の拡開サイズ、内容物の重量等を考慮して適正に設定されるが、５ｍｍ前後の段差が適当である。 Before Kisoko portion 8 forms a step 6 by lengthening the central lower end 5a relative to the left and right sides of the lower end portion 5b and the left and right sides of the lower end portion 5b and the center of the lower end 5a. The step 6 is appropriately set in consideration of the size of the packaging bag 1, the size of the bottom 8 expanded, the weight of the contents, etc., but a step of about 5 mm is appropriate.

さらに包装用袋１は、前記中央の下方端部５ａと左右両側の下方端部５ｂとの間に渡って左右両側の下方端部５ｂよりも上方へ彎曲した形状の欠除部７が設けられた形態をしている。 Further packaging bag 1, cut-off parts 7 of the curved shape upwardly is provided than the left and right sides of the lower end portion 5b over between the center of the lower end portion 5a and the left and right sides of the lower end portion 5b It was in the form.

上記包装用袋１の開口部９は、顧客が手にする時点では多くの場合、開封を必要とする状態にあるから、ノッチ、薄肉線、ミシン目、傷痕群等により開封をし易くする配慮が為されることが望ましい。また、図１及び図２で示すように、開口部９を再開閉するためのファスナー１０を設けた袋であってもよい。   Since the opening 9 of the packaging bag 1 is often in a state that requires opening at the time of the customer's hand, it is easy to open it with notches, thin wires, perforations, scars, etc. It is desirable that Moreover, as shown in FIG.1 and FIG.2, the bag which provided the fastener 10 for opening and closing the opening part 9 may be sufficient.

本発明は上記の通りの構造であるから、包装用袋１内に内容物を包入することで底部８のガゼット２が押し拡がり中央の下方端部５ａが膨らみ厚みができて自立状態となる。この中央の下方端部５ａが膨らむことにより左右両側の下方端部５ｂを内側に引き寄せようとする力が生じるが、この左右両側の下方端部５ｂを内側に引き寄せようとする力を、中央の下方端部５ａと左右両側の下方端部５ｂとの間に渡って左右両側の下方端部５ｂよりも上方へ彎曲した形状の欠除部７で遮断し、これによって左右両側の下方端部５ｂは内側に引き寄せられることなく、その独立性が確保されて自立を安定させる。 Since the present invention has the structure as described above, by enclosing the contents in the packaging bag 1, the gusset 2 of the bottom portion 8 is expanded and the lower end portion 5a at the center swells and becomes self-supporting. . The center lower end portion 5a swells to generate a force that pulls the left and right lower end portions 5b inward. The force to pull the left and right lower end portions 5b inward blocked with lacking part 7 having a shape than the left and right sides of the lower end portion 5b and curved upwards over between the lower end portion 5a and the left and right sides of the lower end portion 5b, whereby the left and right sides of the lower end portion 5b Without being attracted to the inside, its independence is secured and its independence is stabilized.

さらには、左右両側の下方端部５ｂに比し中央の下方端部５ａを長くして左右両側の下方端部５ｂと中央の下方端部５ａとに段差６を設けたことによって、中央の下方端部５ａの浮き上がりが防止される。すなわち、左右両側の下方端部５ｂの接地点を支点にして中央の下方端部５ａが浮き上がった隙間分で厚み方向に揺動するガタつきが押えられ、幅広で剛性を有する中央の下方端部５ａと、同じく剛性を有し前述のように独立性が確保された左右両側の下方端部５ｂとの荷重分散により、極めて安定性の高い自立機能を果たせしめるものである。   Further, the lower end 5a at the center is made longer than the lower ends 5b on the left and right sides, and a step 6 is provided on the lower end 5b on the left and right sides and the lower end 5a at the center, thereby lowering the center. The lifting of the end 5a is prevented. In other words, the center lower end portion having a wide and rigid center is held by the gap where the center lower end portion 5a is lifted with the contact point of the lower end portion 5b on both the left and right sides as a fulcrum. A highly stable self-supporting function can be achieved by load distribution between 5a and the lower end portions 5b on both the left and right sides, which are also rigid and assured independence as described above.

このように、段差６を適当ならしめることによって、幅広で剛性を有する中央の下方端部５ａと、同じく剛性を有し前述のように独立性が確保された左右両側の下方端部５ｂとの荷重分散を図ることができるようにすることが望ましいが、横幅のある袋や折り込みの深い袋にあっては、左右両側の下方端部５ｂが内側に引き寄せられないようにするだけで、必要十分な自立安定性が得られるような場合もあるから、左右両側の下方端部５ｂの接地は必須要件ではないものである。   In this way, by appropriately leveling the step 6, the wide and rigid central lower end portion 5a and the left and right lower end portions 5b having the same rigidity and ensuring independence as described above are provided. It is desirable to be able to distribute the load. However, in the case of a bag with a wide width or a deeply folded bag, it is necessary and sufficient only to prevent the lower ends 5b on both the left and right sides from being pulled toward the inside. Therefore, it is not essential to ground the lower ends 5b on the left and right sides.

上記の実施形態では、中央の下方端部５ａと左右両側の下方端部５ｂとの間に渡って左右両側の下方端部５ｂよりも上方へ欠除された欠除部７について、これを弯曲形状で説明したが、この欠除部７を図３（Ａ）〜図３（Ｄ）で示すような形状としても本発明の作用効果は得られる。 In the above-described embodiment, the cutout portion 7 that is cut upward from the lower end portions 5b on both the left and right sides across the lower end portion 5a on the left and right sides of the center is bent. Although described with respect to the shape, the effect of the present invention can be obtained even if the cutout portion 7 is shaped as shown in FIGS. 3 (A) to 3 (D) .

ちなみに図３についていうと、図３（Ａ）の場合は円形の欠除部７、図３（Ｂ）の場合は角形の欠除部７、図３（Ｃ）の場合はヘの字形の欠除部７、図３（Ｄ）の場合は台形の欠除部７がそれぞれ示されている。この他本発明の趣旨に則った見栄えをよくするデザインの採用、足場を固める設計変更がなされてよい。 Incidentally, referring to FIG. 3 , in the case of FIG. 3 (A), a circular notched portion 7, in the case of FIG. 3 (B) a rectangular notched portion 7, and in the case of FIG. In the case of the removal part 7 and FIG. 3 (D), a trapezoidal removal part 7 is shown. In addition, a design that improves the appearance in accordance with the gist of the present invention and a design change that solidifies the scaffold may be made.

図４の実施例は、図４（イ）に示すような通常の自立性包装用袋１の表裏底部のそれぞれに、図４（ロ）に示すような剛性の帯状フィルム１１を図４（ハ）に示すように接着一体化し、当該帯状フィルム１１に本発明の趣旨に則った段差６と欠除部７との関係を適用したものである。これによって、この種包装袋の生産効率を上げ、よりしっかりした剛性を底部に付与するという工夫ができる。 In the embodiment shown in FIG. 4, a belt-like film 11 having a rigidity as shown in FIG. 4 (b) is applied to each of the front and back bottom portions of a normal self-supporting packaging bag 1 as shown in FIG. 4 (a). bonding integrated as shown in), is obtained by applying the relationship between the step 6 and the lacking part 7 in line with the spirit of the present invention to the film web 11.
