Description

この発明は、例えば、紙おむつ、トイレットペーパー等の包装に用いられる提げ手付熱可塑性合成樹脂薄材製包装用袋に関する。   The present invention relates to a packaging bag made of a thermoplastic synthetic resin thin material with a handle used for packaging, for example, a paper diaper or toilet paper.

従来のこの種の提げ手付熱可塑性合成樹脂薄材製包装用袋は、以下のように大別できる。
１．特開平２０００−１０９０９４号に示されるように、包装用袋の前後壁の各々の重合部分（いわゆるリップ部）の内面に提げ手の下端部が熱融着され、提げ手が袋本体上方に突出している。
２．図10に示されるように、袋本体（11）のまち部内に、提げ手（13）が袋本体上面長さ方向に沿って重合され、両端が袋本体（11）に熱融着されている（特開平７−３２９９８８号参照）。
３．図11に示されるように袋本体（21）前後壁の上方延長面に手指差し入れ可能な横長孔（22）が設けられ、上方延長面全体が提げ手（23）となされている。
特開平２０００−１０９０９４号公報（図１） 特開平７−３２９９８８号公報（代表図） Conventional types of bags made of thermoplastic synthetic resin thin materials with a handle like this can be broadly classified as follows.
1. As shown in Japanese Patent Application Laid-Open No. 2000-109094, the lower end portion of the handle is heat-sealed to the inner surface of each overlapping portion (so-called lip portion) of the front and rear walls of the packaging bag, and the handle protrudes upward from the bag body. ing.
2. As shown in FIG. 10, the litter (13) is polymerized along the length of the upper surface of the bag body, and both ends are heat-sealed to the bag body (11) in the town part of the bag body (11). (See JP-A-7-329988).
3. As shown in FIG. 11, a laterally long hole (22) into which a finger can be inserted is provided on the upper extension surface of the front and rear walls of the bag body (21), and the entire upper extension surface serves as a hand (23).

しかしながら、いずれのタイプにせよ、提げ手（13）（23）を掴んで提持する場合は何ら支障はないが、提げ手（13）（23）の長さが相対的に短いので、提げ手（13）（23）に腕を通して包装用袋を腕で吊下げることができない。
もとより、上記１のタイプにおいては、提げ手を長くすることにより腕を通せるようにすることが可能であるが、長くなった提げ手が袋本体前面に垂れ下がると、袋本体前面の印刷表示内容が見づらくなり、店頭において複数段に積み重ねて陳列した際のディスプレイ効果が妨げられる。
また、上記２のタイプにおいても、腕を通せるように提げ手（13）を長くすることが可能であるが、袋本体上面にたるんだような状態の提げ手（13）を取り付けることは、大量生産するための一連の製作工程の中ではいささか難しい。
さらに、上記１〜２のタイプは、袋本体前後壁上端部が内側に折り返されたいわゆるリップ部を有し、上記３のタイプは、袋本体前後壁が上方に延長されており、袋本体構成薄材が実質的に被包装物を包装する部分以外に使用されている。
この発明は、上記課題を解決することをなされたもので、提げ手に腕を通すことができることはもとより、提げ手不使用時には提げ手の存在が邪魔にならず、かつ材料コスト的にも安価に製作できる提げ手付熱可塑性合成樹脂薄材製包装用袋を提供することを目的とする。 However, in any type, there is no problem when holding and holding the hand (13) (23), but the length of the hand (13) (23) is relatively short. (13) The packaging bag cannot be suspended by the arm through the arm in (23).
Of course, in the above type 1, it is possible to allow the arm to pass through by making the extender longer, but when the extended extender hangs down on the front side of the bag body, the printed display contents on the front side of the bag body It becomes difficult to see, and the display effect when stacked and displayed in a plurality of stages at the store is hindered.
Also, in the above two types, it is possible to lengthen the hand (13) so that the arm can pass through, but attaching the hand (13) in a slack state on the upper surface of the bag body It is somewhat difficult in a series of production processes for mass production.
Further, the above types 1 and 2 have a so-called lip portion in which upper ends of the front and rear walls of the bag body are folded inward, and the above 3 types have a bag body configuration in which the front and rear walls of the bag body are extended upward. Thin materials are used in areas other than the portion where the material to be packaged is substantially packaged.
The present invention has been made to solve the above-mentioned problems. In addition to being able to pass the arm through the hand, the presence of the hand does not get in the way when the hand is not used, and the material cost is low. It is an object of the present invention to provide a packaging bag made of a thin thermoplastic synthetic resin material with a handle that can be manufactured.

上記目的を達成するために、この発明は、熱可塑性合成樹脂製薄材からなる袋本体に、提げ手が設けられてなる提げ手付熱可塑性合成樹脂薄材製包装用袋において、袋本体は、被包装物が充填された状態のもとで、上端左右両端部に被包装物未充填の三角形状余剰部が形成されてなる形態のものであって、提げ手が、その両端部が前記三角形状余剰部に接合されてなる構成を採用する。   In order to achieve the above object, the present invention provides a bag-made thermoplastic synthetic resin thin material packaging bag in which a hand is provided on a bag body made of a thin thermoplastic synthetic resin material. Under the condition that the package is filled, a triangle-shaped surplus portion that is not filled with the package is formed on the left and right ends of the upper end. The structure joined to the shape surplus part is employ | adopted.

袋本体は、１枚の熱可塑性合成樹脂製薄材が二つ折りされ、その両端が熱融着されて作製されてなるものであることが好ましい。提げ手の取付が行い易いからである。
提げ手は、熱可塑性合成樹脂薄材からなり、その両端部が前記三角形状余剰部に熱融着されてなることが好ましい。袋本体成形時に提げ手を同時に取り付けることができるからである。
また、提げ手は、前記二つ折り頂部に跨って設けられてなることが好ましい。比較的広幅の提げ手を合理的に袋本体に取り付けることができるからである。 The bag body is preferably formed by folding a single sheet of thermoplastic synthetic resin into two, and heat-sealing both ends thereof. This is because it is easy to attach the litter.
The litter is preferably made of a thin thermoplastic synthetic resin, and both ends thereof are preferably heat-sealed to the triangular surplus portion. This is because the hand can be attached at the same time when the bag body is molded.
Moreover, it is preferable that a litter is provided ranging over the said bifold top part. This is because a relatively wide hand can be reasonably attached to the bag body.

この発明によれば、提げ手を上方に引き上げると、提げ手両端部に従って三角形状余剰部が上方に引き上げられ、該三角形状余剰部が実質的に提げ手の下端部を構成することとなることによって、提げ手の実質的長さが伸張し、袋本体上面との間に大きな空間が得られ、腕を通すことが可能となり、使い勝手の良い提げ手付熱可塑性合成樹脂薄材製包装用袋を提供できる。
また、提げ手は、その不使用時に袋本体前面に垂れ下がることがないので、店頭における展示陳列時に、ディスプレー効果を妨げることがない。
これらに加えて、袋本体を構成する熱可塑性合成樹脂薄材の余剰部分を合理的に利用できるので、材料コスト的にコストアップを招来することがない。 According to the present invention, when the extender is lifted upward, the triangular surplus portion is lifted upward in accordance with both ends of the extender, and the triangular surplus portion substantially constitutes the lower end of the extender. By extending the effective length of the hand, a large space can be obtained between the top of the bag body, and the arm can be passed through. Can be provided.
Further, since the litter does not hang down on the front surface of the bag body when not in use, the display effect is not hindered when the display is displayed at the store.
In addition to these, since the surplus portion of the thermoplastic synthetic resin thin material constituting the bag body can be reasonably used, there is no cost increase in terms of material cost.

提げ手が、熱可塑性合成樹脂薄材からなり、その両端部が前記三角形状余剰部に熱融着されてなる場合には、袋本体成形時に提げ手を同時に取り付けることができ、提げ手付熱可塑性合成樹脂薄材製包装用袋を合理的に作製できる。
また提げ手が、前記二つ折り頂部に跨って設けられてなる場合には、比較的広幅の提げ手を有し、提持の行いやすい提げ手付熱可塑性合成樹脂薄材製包装用袋を合理的に作製できる。 When the litter is made of a thin thermoplastic synthetic resin and its both ends are heat-sealed to the triangular surplus, the litter can be attached at the same time as the bag body is molded, A synthetic resin thin packaging bag can be reasonably produced.
In addition, if the litter is provided across the bi-fold crest, it has a relatively wide limp, and it is reasonable to use a thermoplastic synthetic resin thin packaging bag with a lipper that is easy to carry. Can be made.

以下、この発明に係る提げ手付熱可塑性合成樹脂薄材製包装用袋の実施形態を図面に基づいて説明する。

袋本体（１）は、ポリエチレン等からなる１枚の熱可塑性合成樹脂薄材が二つ折りにされ、その両端が熱融着されて作製されてなるもので、その製造方法は、この種の熱可塑性合成樹脂製薄材製包装用袋の製造方法と同様である。（７）は、両端熱融着部である。
すなわち、袋本体（１）は、図３に示すように、長尺の１枚の袋本体構成用ポリエチレンシート（Ｓ１）又はポリエチレンフィルムを二つ折りにして、袋本体（１）の前壁（１ａ）及び後壁（１ｂ）となる領域どうしを上下方向に少しずらした状態で重ね合わせた後、所定幅ごとに熱溶着と同時に切断することにより作製されたものである。図中、（７ａ）は袋本体左右両端の熱融着部予定位置である。 DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a packaging bag made of thermoplastic synthetic resin thin material according to the present invention will be described with reference to the drawings.
1 to 6 of the first embodiment of the thin packaging thermoplastic synthetic resin packaging bag (A), the bag body (1) is filled with an article to be packaged at the upper left and right ends. The handle (3) is attached to the bag body with both ends thereof heat-sealed to a pair of triangular-shaped surplus portions (2) (2) that are not filled with the package to be formed.
The bag body (1) is produced by folding a single thermoplastic synthetic resin thin material made of polyethylene or the like into two folds and thermally fusing both ends thereof. This is the same as the manufacturing method of the plastic synthetic resin thin packaging bag. (7) is a both-end heat fusion part.
That is, as shown in FIG. 3, the bag main body (1) is formed by folding a long single bag main body constituting polyethylene sheet (S1) or polyethylene film and folding the front wall (1a) of the bag main body (1). ) And the region to be the rear wall (1b) are overlapped with each other being slightly shifted in the vertical direction, and then cut at the same time as thermal welding for each predetermined width. In the figure, (7a) is the heat fusion part planned positions at the left and right ends of the bag body.

提げ手（３）は、同じく長尺の提げ手構成用ポリエチレンシート（Ｓ２）又はポリエチレンフィルムを二つ折りにしたものを、前記袋本体（１）を作製する際に、袋本体（１）の二つ折り頂部（１ｃ）に被せて沿わせるように跨らせた後、その両端部を袋本体（１）の前記三角形状余剰部（２）（２）に熱溶着することにより、袋本体（１）に取り付けられたものである。前記提げ手構成用ポリエチレンシート（Ｓ２）の二つ折り頂部（３ｃ）には、袋本体端部に相当する位置に所定間隔をおいて図２に示すような切目（４）が設けられている。
図４は、提げ手（３）と袋本体（１）との熱溶着部を示すもので、提げ手を引っ張り上げて使用する際に、一対の三角形状余剰部（２）（２）に対応するように設定された斜状熱溶着部（５ａ）とその先端に連なる一文字状部（５ｂ）とからなる主熱溶着部（５）と、該主熱溶着部（５）の下方位置における補強熱溶着部（６）を介して、提げ手（３）が袋本体（１）に熱溶着されている。前記補強熱溶着部（６）は、図示するように袋本体幅方向中央部に向かう一端が上方に向かってカールしたような鉤型に形成されている。この補強熱溶着部（６）は、単なる一文字状でも構わないが、鉤型に形成されていることが好ましい。単なる一文字状よりも前記一端が鉤型に形成されている方が、強度が高まるからである。 The hand (3) is formed by folding the long hand structure polyethylene sheet (S2) or the polyethylene film into two when the bag body (1) is produced. After straddling over the folded top (1c), both ends thereof are thermally welded to the triangular surplus portions (2) and (2) of the bag main body (1), whereby the bag main body (1 ). A cut (4) as shown in FIG. 2 is provided at a position corresponding to the end portion of the bag body at a predetermined interval in the folded top part (3c) of the polyethylene sheet for constructing the hand (S2).
FIG. 4 shows the heat-welded part between the hand (3) and the bag body (1). When the hand is pulled up and used, it corresponds to a pair of triangular surplus parts (2) and (2). A main heat welded portion (5) composed of an oblique heat welded portion (5a) set so as to have a character-like portion (5b) connected to the tip thereof, and reinforcement at a position below the main heat welded portion (5) The litter (3) is thermally welded to the bag body (1) through the heat welded part (6). As shown in the drawing, the reinforcing heat welding portion (6) is formed in a bowl shape in which one end toward the center portion in the width direction of the bag body is curled upward. The reinforcing heat welding portion (6) may be a simple single character, but is preferably formed in a bowl shape. This is because the strength is enhanced when the one end is formed in a bowl shape rather than a simple one-letter shape.

上記構成を有する提げ手付熱可塑性合成樹脂製薄材製包装用袋（Ａ）は、袋本体（１）に所定の被包装物が充填され、下部開口部を封緘すると、図２に示すような包装状態が得られる。この時、提げ手（３）は、製作途上の二つ折り状態から平らになって、袋本体（１）の上面に、沿うように位置して、製作途上に二つ折り状態における提げ手（３）の二つ折り頂部（３ｃ）と袋本体（１）の二つ折り頂部（１ｃ）とが重なり合うこととなる。
通常は、店頭においてこのような状態で多数個が積み重ねられて展示陳列されるものであるから、提げ手（３）が袋本体（１）前面に垂れ下がることがないので、ディスプレー効果が妨げられることがない。
購買者が持ち帰りる際には、提げ手（３）を掴んで上方に引っ張り上げると、図１に示すように提げ手（３）と袋本体（１）との間に、腕を通せるだけの十分な空間が得られることになる。 As shown in FIG. 2, the thermoplastic synthetic resin thin packaging bag (A) having the above structure is filled with a predetermined packaged article in the bag body (1) and seals the lower opening. A packaging state is obtained. At this time, the hand (3) is flattened from the half-folded state in the course of production and is positioned along the upper surface of the bag body (1), and the hand (3) in the half-folded state during the production. The two-fold crest (3c) and the two-fold crest (1c) of the bag body (1) overlap.
Usually, a large number of items are stacked and displayed in such a state at the storefront, so the litter (3) does not hang down from the front of the bag body (1), and the display effect is hindered. There is no.
When the purchaser takes home, if he holds the hand (3) and pulls it upwards, he can pass his arm between the hand (3) and the bag body (1) as shown in FIG. A sufficient space will be obtained.
