Description

本発明は、易開封性包装袋、さらに詳しくは、相対面するシートの周縁部が重ね合わされてシールされ、そのシールされたシール部で包囲されるように、各種の被収容物を、密封状態で収容しうる収容部を形成し、シール部の一側縁の開封起点部を起点として引き裂くことにより、収容部が開封されて、その一部に被収容物を取り出すことのできる取出口が形成されるように構成された易開封性包装袋に関する。   The present invention relates to an easy-open packaging bag, more specifically, various kinds of objects to be sealed in a sealed state so that the peripheral edge portions of the facing sheets are overlapped and sealed, and surrounded by the sealed seal portion. Forming an accommodating portion that can be accommodated in the container, and tearing the opening starting point at one side edge of the seal portion as a starting point, thereby opening the accommodating portion and forming an outlet from which a portion to be accommodated can be taken out The present invention relates to an easy-open packaging bag configured as described above.

一般に、液状食品、粉末状食品、飲料、調味料、洗剤、シャンプー、化粧料等、小分け包装や詰め替え用等として使用される被収容物は、パウチと称される密封用の易開封性の包装袋に包装されている。このような易開封性包装袋は、相対面するシートの周縁部が重ね合わされてシールされ、そのシールされたシール部で包囲されるように、各種の被収容物を、密封状態で収容しうる収容部を形成した構成からなるものであり、３方の周縁部がシールされたものが３方パウチ、４方の周縁部がシールされたものが４方パウチ等と称されている。 Generally, liquid foods, powdered foods, beverages, seasonings, detergents, shampoos, cosmetics, etc., contained items used for subpackaging or refilling, are easy-open packaging for sealing called pouches. Packaged in a bag. Such an easy-open packaging bag can accommodate various items to be sealed in a sealed state so that the peripheral portions of the facing sheets are overlapped and sealed, and surrounded by the sealed seal portion. It is composed of a structure in which a housing portion is formed, and a three-sided pouch having a three-sided peripheral part sealed is called a four-way pouch or the like having a four-sided peripheral part sealed.

そして、このような包装袋においては、周縁部のシール部の一側縁にノッチと称される開封起点部が形成され、その開封起点部を起点として引き裂くことにより、収容部が開封されて該収容部の一部に被収容物を取り出すことのできる取出口が形成されるように構成されている。 In such a packaging bag, an opening start point portion called a notch is formed on one side edge of the seal portion at the peripheral portion, and the container portion is opened by tearing the opening start point portion as a starting point. A take-out port through which the object can be taken out is formed in a part of the containing portion.

このような易開封性包装袋は、上記のように開封起点部の近傍を指で把持し、その開封起点部を起点として引き裂くことによって包装袋を開封するものであるが、開封起点部の近傍を指で把持して引き裂こうとするときに、指が滑って引き裂き作業を行いにくい場合がある。 Such an easy-open packaging bag, as described above, grips the vicinity of the opening start point with a finger and tears the opening start point as a starting point to open the packaging bag, but in the vicinity of the opening start point. There are cases where it is difficult to perform the tearing work because the finger slips when the finger is gripped with a finger and is torn.

そこで、このような点に鑑み、たとえば下記特許文献１や特許文献２のような特許出願がなされている。この特許文献１に記載された発明は、請求項１に記載されているように、「フィルムを重ね周縁を接合して液剤が収容できるように成形されたパウチであって、切断誘導線に沿って切除部を切除したとき切断誘導線の位置を注出口とする液剤の注出路を形成し、その切除部に指掛孔または凹凸模様からなる１以上の滑り止め手段が設けられたことを特徴とする易開口性パウチ」に係るものである。 In view of this, patent applications such as Patent Document 1 and Patent Document 2 below have been filed. As described in claim 1, the invention described in Patent Document 1 is “a pouch that is formed so that a liquid agent can be accommodated by laminating a film and joining the peripheral edges, and along the cutting guide line. When the excision part is excised, a liquid drug extraction path is formed with the position of the cutting guide line as the spout, and the excision part is provided with one or more anti-slip means comprising a finger hole or an uneven pattern. Is related to “easily openable pouch”.

しかしながら、上記特許文献１に記載された易開封性の包装袋のように、凹凸模様等の滑り止め手段を設けた構造のものにおいては、必ずしも安定した滑り止め効果が得られるわけではなく、また、引っ張り方向によっては十分な効果が得られないという問題点があった。 However, in the case of a structure provided with anti-slip means such as a concavo-convex pattern such as the easy-open packaging bag described in Patent Document 1, a stable anti-slip effect is not always obtained, and However, there is a problem that a sufficient effect cannot be obtained depending on the pulling direction.

In addition, a so-called aluminum laminate sheet or the like in which aluminum is laminated can be used.

表側シート２と裏側シート３との周縁部は熱シール、超音波シール等によってシールされ、その周縁部のシール部分で包囲された部分はシールされることなく、図２乃至図５に示すように、上側シート２と下側シート３間に被収容物を収容することができる空間を有する収容部４が形成されている。本実施形態においては、包装袋１の上部、底部、及び両側部に、それぞれ上部シール部５ａ、側部シール部５ｂ、５ｃ、底部シール部５ｄが形成されて、収容部４を包囲する４方がシールされた、いわゆる４方パウチと称される形態の包装袋１が形成されている。 As shown in FIGS. 2 to 5, the peripheral portions of the front side sheet 2 and the back side sheet 3 are sealed by heat sealing, ultrasonic sealing or the like, and the portion surrounded by the sealing portion of the peripheral portion is not sealed. An accommodating portion 4 having a space in which an object can be accommodated is formed between the upper sheet 2 and the lower sheet 3. In the present embodiment, the upper seal portion 5a, the side seal portions 5b, 5c, and the bottom seal portion 5d are formed on the top, bottom, and both sides of the packaging bag 1, respectively, so as to surround the accommodating portion 4. A packaging bag 1 in a form called a so-called four-way pouch is formed.

４方のシール部５ａ、５ｂ、５ｃ、５ｄで包囲された収容部４は、全体が正面略平行四辺形状に形成されており、その上部右側と下部左側には略半円状の円弧状部４ａ、４ｂが形成されている。また収容部４の上部左側と下部右側には、斜辺部４ｃ、４ｄが形成されている。そして、その上部左側の斜辺部４ｃから上部右側の円弧状部４ａの部分にかけて、被収容物を取り出すための取出口１３を形成する取出口形成部６として形成されている。この取出口形成部６の側方であって、包装袋１の上部の一側縁部には、開封起点部であるノッチ７が形成されている。このノッチ７は、スリット状の切り込みによって形成されたものである。   The housing part 4 surrounded by the four seal parts 5a, 5b, 5c, and 5d is formed in a substantially parallelogram shape on the front, and a semicircular arc-shaped part on the upper right side and the lower left side thereof. 4a and 4b are formed. Further, oblique side portions 4c and 4d are formed on the upper left side and the lower right side of the accommodating portion 4, respectively. And it forms as the outlet formation part 6 which forms the outlet 13 for taking out a to-be-contained object from the oblique side part 4c of the upper left side to the arc-shaped part 4a of the upper right side. A notch 7 that is an opening start point is formed on one side edge of the upper portion of the packaging bag 1 on the side of the outlet forming portion 6. This notch 7 is formed by a slit-like cut.

この開封起点部であるノッチ７の直近上部であって、引き裂く際の指の把持部分には、正面視において、引き裂き方向と反対側に突出する略半円状の突起リブ８が形成されている。この突起リブ８は、略半円状の円弧を形成する一端部８ａと他端部８ｂとを結ぶ線が垂直方向から少し斜めに傾斜するように形成されている。   A substantially semicircular protruding rib 8 that protrudes in the opposite direction to the tearing direction when viewed from the front is formed in the gripping part of the finger when tearing, immediately above the notch 7 that is the opening start point. . The protruding rib 8 is formed such that a line connecting the one end 8a and the other end 8b forming a substantially semicircular arc is slightly inclined from the vertical direction.

その状態で、図９に示すように、易開封性包装袋１の上部シール部５ａを、前記ノッチ７が形成されている易開封性包装袋１の一側縁側から他側縁側に向かって引き裂く。このように上部シール部５ａを一側縁側から他側縁側に向かって引き裂くことで、同図に示すように、上部シール部５ａが引き裂かれて、取出口１３が形成されることとなる。 In this state, as shown in FIG. 9, the upper seal portion 5a of the easy-open packaging bag 1 is torn from one side edge side to the other side edge side of the easy-open packaging bag 1 in which the notch 7 is formed. . Thus, by tearing the upper seal portion 5a from the one side edge side toward the other side edge side, the upper seal portion 5a is torn as shown in FIG.

この場合において、易開封性包装袋１を開封する前に、使用者は一方の指１４で上記のような引き裂き方向と反対側に突出する略半円状の突起リブ８を把持しており、突起リブ８が略半円状に突出する部分と反対側に上部シール部５ａを引き裂いていくので、その略半円状の突起リブ８の内側に沿って滑り防止作用が効果的に発揮されることとなり、その結果、ノッチ７を開封起点として引き裂く際に、引き裂き力が加わる方向が多少変動しても、滑り防止作用が低減することがない。   In this case, before opening the easy-open packaging bag 1, the user grasps the substantially semicircular projecting rib 8 protruding on the opposite side to the tearing direction with one finger 14, Since the upper seal portion 5a is torn away from the portion where the protruding rib 8 protrudes in a substantially semicircular shape, an anti-slip action is effectively exhibited along the inner side of the approximately semicircular protruding rib 8. As a result, when tearing with the notch 7 as the opening start point, even if the direction in which the tearing force is applied fluctuates somewhat, the anti-slip effect is not reduced.

特に、突起リブ８は、略半円状の円弧を形成する一端部８ａと他端部８ｂとを結ぶ線が垂直方向から少し斜めに傾斜するように形成されているため、引き裂き力が加わる方向が変動することによっても滑り防止作用を維持できる効果が一層良好となる。 In particular, the protruding rib 8 is formed such that a line connecting the one end 8a and the other end 8b forming a substantially semicircular arc is slightly inclined from the vertical direction, so that a tearing force is applied. The effect of maintaining the anti-slip action can be further improved even when the angle fluctuates.

さらに、突起リブ８の略半円状の円弧の中心点となる部分には、補助突起９が形成されているため、使用者が一方の指１４で突起リブ８を把持したとき、その突起リブ８の略半円状の円弧の中心点となる部分に位置する補助突起９も同時に把持することとなり、記突起リブ８による指の滑り防止効果を補完して、その滑り防止効果が一層良好となる。   Further, since the auxiliary protrusion 9 is formed at the center point of the substantially semicircular arc of the protruding rib 8, when the user grips the protruding rib 8 with one finger 14, the protruding rib 9 The auxiliary projection 9 positioned at the center point of the substantially semicircular arc of 8 is also gripped at the same time, complementing the anti-slip effect of the finger by the projection rib 8 and further improving the anti-slip effect. Become.

さらに、収容部４の上部側には、上記のように、斜め縦方向に取出口変形防止用リブ１１が形成されているため、ノッチ７を開封起点として易開封用包装袋１を開封した後に、取出口６がいびつに変形したり潰れたりすることで開口面積が小さくなることが防止され、その取出口６の形状が維持されることとなる。 Furthermore, since the outlet deformation preventing rib 11 is formed obliquely in the vertical direction on the upper side of the accommodating portion 4, after opening the easy-open packaging bag 1 with the notch 7 as an opening start point, The opening 6 is prevented from becoming small by deforming or crushing the outlet 6 and the shape of the outlet 6 is maintained.

そして、上記のように易開封性包装袋１の上部シール部５ａを一側縁側から他側縁側に向かって引き裂き、その引き裂かれた上部シール部５ａを切り取って除去することにより、取出口６が完全に開口した状態で、図１０に示すように、易開封性包装袋１の上部と下部とを反転させると、同図に示すように、被収容物である粉体１６が取出口６から排出されることとなる。 Then, as described above, the upper seal portion 5a of the easy-open packaging bag 1 is torn from the one side edge side toward the other side edge side, and the torn outlet seal 6a is cut off and removed, whereby the take-out port 6 is removed. When the upper portion and the lower portion of the easy-open packaging bag 1 are reversed as shown in FIG. 10 in the fully opened state, the powder 16 that is an object to be contained is removed from the outlet 6 as shown in FIG. Will be discharged.

この場合において、易開封性包装袋１の上部には、斜辺部４ｃが形成されているため、易開封性包装袋１の上部が下向きとなるように易開封性包装袋１を反転させた状態において、取出口６が横方向に広がるように開口させると、その取出口６の近辺の形状は、上記斜辺部４ｃに沿って略漏斗状の形状となり、その結果、その略漏斗状の形状に沿って粉体１６は取出口６の近傍に収束されやすい状態となり、取出口６から排出されやすい状態になるとともに、粉体の飛び散りも好適に防止されることとなる。 In this case, since the oblique side portion 4c is formed in the upper portion of the easy-open packaging bag 1, the easy-open packaging bag 1 is inverted so that the upper portion of the easy-open packaging bag 1 faces downward. When the outlet 6 is opened so as to spread in the lateral direction, the shape of the vicinity of the outlet 6 becomes a substantially funnel shape along the oblique side portion 4c, and as a result, the shape becomes a substantially funnel shape. Accordingly, the powder 16 is likely to be converged in the vicinity of the outlet 6, and is easily discharged from the outlet 6, and powder scattering is also suitably prevented.

一方、易開封性包装袋１の上部と下部とが反転した状態において、上側に位置している収容部４の下部においては、略半円状の円弧状部４ｂと斜辺部４ｄとによって、粉溜まりが防止される。すなわち、収容部４の下部の両側に角部が存在するような形状であれば、その角部の近傍に収容物である粉体１６が不用意に貯留されるおそれがあるが、本実施形態では、収容部４の下部が、円弧の径が比較的大きい略半円状の円弧状部４ｂと、斜辺部４ｄとを具備して構成されているので、収容部４の下部に粉体１６が不用意に貯留されるのが好適に防止されることとなるのである。 On the other hand, in the state where the upper part and the lower part of the easy-open packaging bag 1 are inverted, the lower part of the housing part 4 located on the upper side is formed by the substantially semicircular arc-shaped part 4b and the oblique part 4d. Accumulation is prevented. That is, if the shape has corners on both sides of the lower part of the container 4, the powder 16 as the container may be inadvertently stored near the corners. Then, since the lower part of the accommodating part 4 is comprised including the substantially semicircular arc-shaped part 4b with a comparatively large circular arc diameter, and the hypotenuse part 4d, the powder 16 is formed in the lower part of the accommodating part 4. Is prevented from being stored carelessly.

尚、上記実施形態では、易開封性包装袋１を構成する表側シート２と裏側シート３とが、ポリエチレン、ポリプロピレン、ポリエチレンテレフタレート、ポリアミド、或いはこれらの合成樹脂層を複数層に積層したようなもの、さらには上記のような合成樹脂層に、アルミニウムをラミネートしたようないわゆるアルミラミネートシート等を使用する場合について説明したが、表側シート２及び裏側シート３の材質はこれに限定されるものではなく、これら以外の合成樹脂を用いることも可能である。   In the above embodiment, the front side sheet 2 and the back side sheet 3 constituting the easy-open packaging bag 1 are such that polyethylene, polypropylene, polyethylene terephthalate, polyamide, or a synthetic resin layer thereof is laminated in a plurality of layers. Further, the case where a so-called aluminum laminate sheet or the like in which aluminum is laminated on the synthetic resin layer as described above is used, but the material of the front side sheet 2 and the back side sheet 3 is not limited to this. It is also possible to use synthetic resins other than these.

さらに、上記実施形態では、易開封性包装袋１の上部、両側部、底部の４方がシールされた、いわゆる４方パウチと称される形態の構成としたが、これに限らず、たとえば上部と両側部の３方、或いは上部と一方の側部及び底部の３方がシールされた、いわゆる３方パウチと称される形態の構成とすることも可能である。要は、被収容物を収容する収容部４を包囲するようにシール部が形成されていればよいのである。ここで、本発明において「易開封性包装袋１の周縁部のシール部によって収容部４を包囲されている」とは、４方の周縁部で包囲されているのみならず、３方の周縁部で包囲されているような場合も含むものである。 Furthermore, in the said embodiment, although it was set as the structure of what was called a so-called 4-way pouch with which the upper part of the easy-open packaging bag 1 and both sides and the bottom part were sealed, it is not restricted to this, For example, upper part It is also possible to adopt a configuration called a so-called three-way pouch in which the three sides on both sides, or the upper side, one side, and the bottom side are sealed. In short, it is only necessary that the seal portion is formed so as to surround the accommodating portion 4 that accommodates the object to be accommodated. Here, in the present invention, “the housing portion 4 is surrounded by the seal portion at the peripheral portion of the easy-open packaging bag 1” is not only surrounded by the four peripheral portions but also the three peripheral portions. This includes the case of being surrounded by a part.

その他、本発明の意図する範囲で任意に設計変更可能である。   In addition, the design can be arbitrarily changed within the range intended by the present invention.
