以下にこの発明の実施形態を図面に示すところに基づいて説明する。
図１に示す包装袋の実施形態において、包装袋１は、シーラント層を含む二層以上の積層構造を持つ２枚の包装用フィルムを、シーラント層が内面側になるように重ね合わせ、該シーラント層同士の融着接合によって、縁部に側部シール部２ａ、２ｂ、上部シール部３および下部シール部４を有すると共に、該シール部２ａ、２ｂ、３、４に囲まれた液状被包装物の充填スペース５を有する。なお、側部シール部２ａ、２ｂ、上部シール部３および下部シール部４は、ヒートシール、インパルスシール、高周波ウエルダーシール、超音波シール、その他によって形成することができる。前記シーラント層としては、ポリオレフィン、エチレン酢酸ビニル共重合体、エチレンエチルアクリレート共重合体、エチレンアクリル酸共重合体、エチレンメタクリル酸共重合体、エチレンメチルメタクリル酸共重合体、アイオノマーなどを用いることが好ましい。
An embodiment of the present invention will be described below with reference to the drawings.
In the embodiment of the packaging bag shown in FIG. 1, the packaging bag 1 is obtained by stacking two packaging films having a laminated structure of two or more layers including a sealant layer so that the sealant layer is on the inner surface side. A liquid packaged object having side seal portions 2a, 2b, an upper seal portion 3 and a lower seal portion 4 at an edge portion by fusion bonding of the layers and surrounded by the seal portions 2a, 2b, 3, 4. With a filling space 5. The side seal portions 2a, 2b, the upper seal portion 3 and the lower seal portion 4 can be formed by heat sealing, impulse sealing, high frequency welder sealing, ultrasonic sealing or the like. As the sealant layer, it is possible to use polyolefin, ethylene vinyl acetate copolymer, ethylene ethyl acrylate copolymer, ethylene acrylic acid copolymer, ethylene methacrylic acid copolymer, ethylene methyl methacrylic acid copolymer, ionomer and the like. preferable.
また、充填スペース５の図１の左右方向中央位置には、該充填スペース５の図１の上下方向に延在する易剥離部６を有し、該易剥離部６によって充填スペース５が２つの収納室５ａ、５ｂに分割されている。なお、使用開始にあたっては、液状被包装物の充填された収納室５ａおよび／または収納室５ｂを手指で押圧し、これによって加圧された液状被包装物によって易剥離部６を剥離することで２つの収納室５ａ、５ｂを連通させることにより、液状被包装物を混合することができる。 Further, at the center of the filling space 5 in the left-right direction in FIG. 1, there is an easy peeling portion 6 extending in the vertical direction of the filling space 5 in FIG. It is divided into storage rooms 5a and 5b. At the start of use, the storage chamber 5a and / or the storage chamber 5b filled with the liquid to be packaged are pressed with fingers, and the easily peelable portion 6 is peeled off by the liquid to be packaged pressed by the finger. By connecting the two storage chambers 5a and 5b to each other, the liquid packaged objects can be mixed.
易剥離部６は、側部シール部２ａ、２ｂ、上部シール部３および下部シール部４に比して接合強度が相対的に低い部分であり、例えば加熱温度および加圧力の少なくとも一方を相対的に小さくしてヒートシール等することにより形成することができる。なお、易剥離部６のシール強度は、充填スペース５への手指による押圧による液状物の圧力によって剥離可能なものとし、好ましくは２〜２０Ｎ／１５ｍｍ幅、より好ましくは５〜１５Ｎ／１５ｍｍ幅とする。また、易剥離部６のシール幅は、とくに限定されるものではないが、１ｍｍ以上、好ましくは３〜１０ｍｍとすることで、充填スペース５を手指で押圧して剥離させる際の、押圧力の調整が容易となる。 The easily peelable portion 6 is a portion having a relatively low bonding strength as compared with the side seal portions 2a, 2b, the upper seal portion 3 and the lower seal portion 4, and for example, at least one of heating temperature and pressure is relatively applied. It can be formed by making it smaller and heat-sealing. The seal strength of the easy peeling portion 6 is such that it can be peeled by the pressure of the liquid substance by pressing the filling space 5 with fingers, and is preferably 2 to 20 N / 15 mm width, more preferably 5 to 15 N / 15 mm width. To do. Further, the seal width of the easy peeling portion 6 is not particularly limited, but by setting it to 1 mm or more, preferably 3 to 10 mm, the pressing force at the time of peeling the filling space 5 by pressing it with fingers is peeled off. Adjustment becomes easy.
図２に、包装袋１を構成する包装用フィルムの一例を示す。この包装用フィルムＦには、幅方向中央部に易剥離部６の形成予定位置に合わせて、文字（ＯＰＥＮ）で構成された模様からなる帯状の印刷層７が設けられている。
なお、印刷層７は、例えば、積層構造からなる包装用フィルムＦの、包装袋１の最外層となるベースフィルム層の内側の面に、凸版印刷（フレキソ）、凹版印刷（グラビア）、平版印刷（オフセット）等によって印刷形成する他、ベースフィルム層とシーラント層との間に設けた中間層等に印刷形成してもよい。
FIG. 2 shows an example of a packaging film that constitutes the packaging bag 1. In this packaging film F, a strip-shaped printing layer 7 having a pattern composed of characters (OPEN) is provided at the central portion in the width direction in accordance with the planned formation position of the easy peeling portion 6.
The printing layer 7 may be, for example, letterpress printing (flexo), intaglio printing (gravure), lithographic printing on the inner surface of the base film layer, which is the outermost layer of the packaging bag 1, of the packaging film F having a laminated structure. Other than printing by (offset) or the like, printing may be performed on an intermediate layer or the like provided between the base film layer and the sealant layer.
包装袋１は、この印刷層７を有する２枚の包装用フィルムＦを、例えば、該印刷層７どうしが重なるように二枚重ねにし、側部シール部２ａ、２ｂおよび下部シール部４を形成して袋状にすると共に、印刷層７位置に沿って、充填スペース５を延在するように２枚の包装用フィルムＦの内表面同士を融着接合させることで易剥離部６を形成して、充填スペース５を２つの収納室５ａ、５ｂに分割し、該収納室５ａ、５ｂ内に上部開口部から所要量の液状被包装物をそれぞれ充填した後、該上部開口部に上部シール部３を設けることで形成することができる。 In the packaging bag 1, two packaging films F having the printing layer 7 are stacked, for example, so that the printing layers 7 are overlapped with each other, and the side seal portions 2a and 2b and the lower seal portion 4 are formed. Along with the bag shape, the easy peeling portion 6 is formed by fusion bonding the inner surfaces of the two packaging films F along the position of the printing layer 7 so as to extend the filling space 5. The filling space 5 is divided into two storage chambers 5a and 5b, and the storage chambers 5a and 5b are each filled with a required amount of liquid object to be packaged through the upper opening, and then the upper sealing portion 3 is provided in the upper opening. It can be formed by providing.
易剥離部６の位置に設けられた印刷層７には、同一の文字“ＯＰＥＮ”からなる模様が表示されているものの、図３（ａ）に拡大して示すように、二枚の包装用フィルムＦはシーラント層どうしが対向するように表裏に重ねられているため、一方の文字が反転した状態で重なり合っているので、目視では模様を文字表示として判別することができない。 Although the pattern composed of the same characters "OPEN" is displayed on the print layer 7 provided at the position of the easy peeling portion 6, as shown in an enlarged view in FIG. Since the film F is superposed on the front and back such that the sealant layers face each other, one of the characters is overlapped in an inverted state, and therefore the pattern cannot be visually identified as a character display.
この易剥離部６を、上記したように手指による押圧によって加圧された液状被包装物による圧力により、側縁部から徐々に剥離させると、図３（ｂ）に示すように剥離した部分では、表裏の包装用フィルムＦが相互に離隔し、該剥離部分に液状被包装物が進入することで印刷層７の文字が浮かびあがり、文字表示として認識できるようになる。したがって、易剥離部６に印刷層７が設けられてなる包装袋１によれば、該印刷層７の表示を観察することで、消費者が易剥離部６の開封状態を目視で確認することができるようになり、安心して使用することができる。 When the easy peeling portion 6 is gradually peeled from the side edge portion by the pressure of the liquid packaged object which is pressed by the finger as described above, the peeled portion is not removed as shown in FIG. 3 (b). The front and back wrapping films F are separated from each other, and the liquid to be packaged enters the peeled portion, so that the characters on the printing layer 7 stand out and can be recognized as a character display. Therefore, according to the packaging bag 1 in which the easy peeling section 6 is provided with the printing layer 7, the consumer can visually confirm the opened state of the easy peeling section 6 by observing the display of the printing layer 7. Now you can use it with confidence.
なお、印刷層７の模様は、文字の他、記号や絵柄、図柄またはこれらの二種以上の組合せによって構成することもでき、例えば、商品名や広告を表示したり、開封手順や使用方法などの注意事項を表示することもできるため、商品の識別性が向上すると共に、使い勝手が良くなるという効果が期待できる。
また、印刷層７の模様の色は、被包装物の色の反対色にする等、該模様が目立つように被包装物に合わせて適宜、選択することが好ましい。
The pattern of the printing layer 7 can be formed by symbols, pictures, patterns, or a combination of two or more of these in addition to characters. For example, a product name or advertisement is displayed, an opening procedure, a method of use, etc. Since it is also possible to display the cautions, it is expected that the product distinguishability is improved and the usability is improved.
The color of the pattern of the printed layer 7 is preferably selected in accordance with the object to be packaged such that the pattern is conspicuous, for example, the color is opposite to the color of the object to be packaged.
なお、印刷層７は、表裏の包装用フィルムＦに形成された模様が重なり合うことで判別できない（隠蔽される）ものであればどのようなものであってもよく、図３（ａ）に示すように同一の文字を表裏の包装用フィルムＦに同一方向で表示させる他、例えば、図４（ａ）に示すように表裏の包装用フィルムＦにそれぞれ異なる文字を表示したり、図４（ｂ）に示すように表裏の包装用フィルムＦで文字の表示方向を変える等、とすることができる。 The printing layer 7 may be of any type as long as the patterns formed on the front and back packaging films F cannot be distinguished (concealed) by overlapping, as shown in FIG. 3 (a). In addition to displaying the same characters on the front and back packaging films F in the same direction, for example, different characters may be displayed on the front and back packaging films F as shown in FIG. ), The display direction of the characters can be changed by the front and back packaging films F.
また、上記したように印刷層７の模様は、易剥離部６が剥離されるまで認識できないため、該模様の表示を観察することで、易剥離部６のシール不良を目視によって確認することができるという効果も期待でき、消費者だけでなく生産者にも優利な効果が得られる。 Further, as described above, the pattern of the printed layer 7 cannot be recognized until the easy peeling portion 6 is peeled off. Therefore, by observing the display of the pattern, it is possible to visually confirm the seal defect of the easy peeling portion 6. The effect of being able to do so can be expected, and it will have a beneficial effect not only on consumers but also on producers.
また、上記実施形態の包装袋１では、易剥離部６を充填スペース５の左右方向中央部に設けているが、充填スペース５を囲繞する側部シール部２ａ、２ｂ、上部シール部３および下部シール部４のうちの１つまたは複数を易剥離部６とし、充填スペース５への手指による押圧によって加圧された液状被包装物によって該易剥離部６を剥離させると共に、易剥離部６位置に設けた印刷層７を表示させるようにしてもよい。 Further, in the packaging bag 1 of the above-described embodiment, the easy peeling portion 6 is provided in the central portion in the left-right direction of the filling space 5, but the side sealing portions 2a and 2b, the upper sealing portion 3 and the lower portion that surround the filling space 5 are provided. One or more of the seal parts 4 are made to be the easy peeling parts 6, and the easy peeling parts 6 are peeled off by the liquid packaged object which is pressed by the finger pressing the filling space 5, and the easy peeling part 6 position You may make it display the printing layer 7 provided in.
次に、包装袋１の他の実施形態を図５に示す。
この実施形態の包装袋１は、図５（ａ）に示すように、シーラント層を含む二層以上の積層構造を持つ１枚の包装用フィルムを、シーラント層が内面側になるように幅方向に折り返して二つ折りにした後、その重なり合う包装用フィルムの上端部、下端部および左側端部をヒートシール等して上部シール部３、下部シール部４および側部シール部２ａを形成した三方シール形の包装袋である。
Next, another embodiment of the packaging bag 1 is shown in FIG.
As shown in FIG. 5 (a), the packaging bag 1 of this embodiment includes a single packaging film having a laminated structure of two or more layers including a sealant layer in the width direction so that the sealant layer is on the inner surface side. After being folded in two and folded in two, the three-sided seal in which the upper sealing portion 3, the lower sealing portion 4 and the side sealing portion 2a are formed by heat-sealing the upper end portion, the lower end portion and the left end portion of the overlapping packaging films. It is a shaped packaging bag.
この包装袋１は、包装用フィルムの折返し辺８近傍位置に、包装袋１の長さ方向に延在するように第１の易剥離部６を有し、該第１の易剥離部６によって上部シール部３、下部シール部４および側部シール部２ａによって囲まれた液状被包装物の充填スペース５と上部シール部３、下部シール部４および折返し辺８によって囲まれた滞留部１２とに区画されている。また、滞留部１２を区画する上部シール部３は、少なくとも一部（図では中央部）が剥離可能（第２易剥離部９）に形成されている。使用開始にあたって、液状被包装物の充填された充填スペース５を手指で押圧すると、これによって加圧された液状被包装物によって第１の易剥離部６が剥離すると共に、充填スペース５内の液状被包装物が滞留部１２へと進入し、さらに充填スペース５を押圧して上部シール部３に設けた第２易剥離部９を剥離させることで液状被包装物を注出することができる。 This packaging bag 1 has a first easy peeling portion 6 at a position in the vicinity of the folding side 8 of the packaging film so as to extend in the length direction of the packaging bag 1, and by the first easy peeling portion 6. In the filling space 5 of the liquid packaged object surrounded by the upper seal part 3, the lower seal part 4 and the side seal part 2a, and the retention part 12 surrounded by the upper seal part 3, the lower seal part 4 and the folded side 8. It is partitioned. Further, at least a part (the central portion in the drawing) of the upper seal portion 3 that divides the retention portion 12 is formed to be peelable (second easy peeling portion 9). At the start of use, when the filling space 5 filled with the liquid packaged object is pressed with fingers, the first easily peelable portion 6 is separated by the liquid packaged object pressed by this, and the liquid in the filling space 5 is also separated. The liquid packaged object can be poured out by allowing the packaged article to enter the retention section 12 and further pressing the filling space 5 to separate the second easy peeling section 9 provided in the upper seal section 3.
この包装袋１では、図５（ａ）に示すように、重なり合う包装用フィルムＦのそれぞれに対し、滞留部１２の形成位置に文字（ＯＰＥＮ）で構成された印刷層７が設けられている。 In this packaging bag 1, as shown in FIG. 5 (a), a printing layer 7 composed of characters (OPEN) is provided at the position where the retention portion 12 is formed for each of the overlapping packaging films F.
この印刷層７は、易剥離部６の剥離前（滞留部１２内への液状被包装物の進入前）には、表裏の模様が重なり、文字を認識することができないのに対し、図５（ｂ）に示すように、易剥離部６を剥離させて液状被包装物が滞留部１２に進入すると、表裏の包装用フィルムＦが相互に離隔し、該滞留部１２に設けた印刷層７の文字が浮かびあがり、文字表示として認識できるようになる。 In the printed layer 7, before the peeling of the easy peeling section 6 (before the liquid packaged object enters the retaining section 12), the patterns on the front and back sides are overlapped and the characters cannot be recognized. As shown in (b), when the easily peelable portion 6 is peeled off and the liquid packaged object enters the retention portion 12, the front and back packaging films F are separated from each other, and the printing layer 7 provided in the retention portion 12 is separated. The character “” appears, and it can be recognized as a character display.
これによれば、消費者が充填スペース５への押圧によって易剥離部６が剥離し、液状被包装物が滞留部１２に進入する様子が目視によって確認することができ、安心して充填スペース５への押圧操作を行うことができる。また、印刷層７は、滞留部１２の他、上部シール部３の第２易剥離部９の形成位置に設けることが好ましく、これによれば、該第２易剥離部９が剥離して液状被包装物が注出する様子を目視によって確認することができる。 According to this, it is possible for the consumer to visually confirm that the easily peelable portion 6 is peeled off by pressing the filling space 5 and the liquid object to be packaged enters the retention portion 12, and to the filling space 5 with confidence. The pressing operation can be performed. In addition, the printing layer 7 is preferably provided at the position where the second easy peeling portion 9 of the upper seal portion 3 is formed in addition to the retention portion 12. According to this, the second easy peeling portion 9 peels off and is in a liquid state. It is possible to visually confirm how the packaged object is poured out.
次に、包装袋１の他の実施形態を図６に示す。
この実施形態の包装袋１は、図６（ａ）に示すように、シーラント層を含む二層以上の積層構造を持つ包装用フィルムを、シーラント層が内面側になるように折り返した後、その両側部どうしを合掌状に重ね合わせて形成した背貼り部１０を有すると共に、該背貼り部１０と、ヒートシール等によって図に斜線を施して示すように形成された上部シール部３および下部シール部４とによって囲まれた液状被包装物の充填スペース５を有する。
Next, another embodiment of the packaging bag 1 is shown in FIG.
As shown in Fig. 6 (a), the packaging bag 1 of this embodiment is obtained by folding a packaging film having a laminated structure of two or more layers including a sealant layer so that the sealant layer is on the inner surface side, and The back sticking portion 10 is formed by overlapping both sides in a palm shape, and the back sticking portion 10 and the upper seal portion 3 and the lower seal portion formed by heat sealing or the like as shown by hatching in the drawing. It has a filling space 5 for the liquid packaged object which is surrounded by the part 4.
背貼り部１０は、包装袋１の両側部間の中間に位置し、その周縁が内縁シール部１０ａ、外縁シール部１０ｂ、上縁シール部１０ｃ、下縁シール部１０ｄによりシールされており、それらのシール部１０ａ〜１０ｄの内側の部分は、表裏の包装用フィルムをヒートシール等することにより形成したシール部からなる隔壁１１によって滞留部１２と注出通路部１３とに区画されている。 The back sticking portion 10 is located in the middle between both side portions of the packaging bag 1, and the peripheral edge thereof is sealed by the inner edge sealing portion 10a, the outer edge sealing portion 10b, the upper edge sealing portion 10c, and the lower edge sealing portion 10d. The inner portions of the sealing portions 10a to 10d are partitioned into a retention portion 12 and a pouring passage portion 13 by a partition wall 11 made of a sealing portion formed by heat-sealing the front and back packaging films.
充填スペース５と背貼り部１０の境界位置となる内縁シール部１０ａは、易剥離部６からなり、背貼り部１０の他の周縁シール部１０ｂ〜１０ｄに比して接合強度が相対的に低い部分であり、例えば加熱温度および加圧力の少なくとも一方を相対的に小さくしてヒートシール等することにより形成することができる。また、内縁シール部１０ａは、充填スペース５に液状被包装物を充填包装した状態で、平坦な姿勢で保管や運搬等した際には、該充填スペース５を押圧しても剥離も破袋もしないが、例えば、背貼り部１０を境として包装袋１を二つに山折りとし、該充填スペース５を厚み方向に押圧した際には剥離することができるような接合強度とすることが好ましい。 The inner edge seal portion 10a, which is the boundary position between the filling space 5 and the spine sticking portion 10, is composed of the easy peeling portion 6, and has a relatively low bonding strength as compared with the other peripheral edge seal portions 10b to 10d of the spine sticking portion 10. It is a portion, and can be formed by, for example, heat sealing or the like while making at least one of the heating temperature and the pressing force relatively small. In addition, the inner edge seal portion 10a can be peeled or broken even when the filling space 5 is pressed when the filling space 5 is filled and packed with a liquid object to be packaged and stored or transported in a flat posture. However, it is preferable that, for example, the packaging bag 1 is folded in two with the back-adhered portion 10 as a boundary, and the bonding strength is such that it can be peeled off when the filling space 5 is pressed in the thickness direction. .
このような包装袋１に対して、図６（ｂ）に示すように背貼り部１０を境にして二つに折り畳み、充填スペース５を押圧（第１押圧）し、液状被包装物による圧力を内縁シール部１０ａに作用させると、内縁シール部１０ａの上部および下部は包装袋１の上部シール部３および下部シール部４によって拘束されているため、開く（剥離する）方向への自由度が低いのに対し、中央部は上記のような拘束力が働かないために自由度が高く、内縁シール部１０ａが該中央部から剥離し始めることになり、充填スペース５からその剥離部分を通って液状被包装物がまず、滞留部１２へと吐出される。
そして、さらに充填スペース５を押圧（第２押圧）すると、内縁シール部１０ａが徐々に剥離された後、滞留部１２および充填スペース５内の液状被包装物が、ゆっくりと注出通路部１３へと誘導され、これにより液状被包装物が穏やかに注出通路部１３から注出されることになる。
As shown in FIG. 6 (b), the packaging bag 1 is folded in two with the spine sticking portion 10 as a boundary, and the filling space 5 is pressed (first pressing), and the pressure applied by the liquid packaged object. Is applied to the inner edge seal portion 10a, the upper and lower portions of the inner edge seal portion 10a are constrained by the upper seal portion 3 and the lower seal portion 4 of the packaging bag 1, so that the degree of freedom in the opening (peeling) direction is reduced. On the other hand, the central portion has a high degree of freedom because the restraining force as described above does not work, and the inner edge seal portion 10a starts to peel off from the central portion, so that the filling space 5 passes through the peeled portion. The liquid packaged object is first discharged to the retention section 12.
Then, when the filling space 5 is further pressed (second pressing), the inner edge seal portion 10a is gradually peeled off, and then the liquid to be packaged in the retention portion 12 and the filling space 5 slowly enters the pouring passage portion 13. The liquid to be packaged is gently poured out from the pouring passage portion 13 as a result.
この実施形態では、図７（ａ）の写真および図８（ａ）の背貼り部１０の拡大図に示すように、背貼り部１０の内縁シール部１０ａ（易剥離部６）位置および滞留部１２位置の包装用フィルムＦに、模様からなる印刷層７が設けられている。印刷層７の模様は、白色の格子状の図柄と文字との組み合わせからなり、充填スペース５内には醤油等の褐色の液状被包装物が充填されている。 In this embodiment, as shown in the photograph of FIG. 7A and the enlarged view of the back sticking portion 10 of FIG. 8A, the position of the inner edge seal portion 10a (easy peeling portion 6) of the back sticking portion 10 and the retention portion. A printing layer 7 having a pattern is provided on the packaging film F at 12 positions. The pattern of the printing layer 7 is made up of a combination of a white grid pattern and letters, and the filling space 5 is filled with a brown liquid packaged object such as soy sauce.
図７（ａ）および図８（ａ）から分かるように、内縁シール部１０ａの剥離前（滞留部部１２内への液状被包装物の進入前）には、表裏の模様が重なり、とくに文字を認識することができないのに対し、図７（ｂ）および図８（ｂ）に示すように、液状被包装物によって内縁シール部１０ａを剥離させて、滞留部１２内に液状被包装物を進入させると、褐色の液状被包装物によって白色の図柄と文字が浮かびあがり、表示として認識することができるようになる。 As can be seen from FIGS. 7 (a) and 8 (a), before the peeling of the inner edge seal portion 10a (before the liquid packaged object enters the retaining portion 12), the patterns on the front and back sides overlap, and particularly 7 (b) and 8 (b), the inner edge seal portion 10a is peeled off by the liquid packaged object, and the liquid packaged object is retained in the retention part 12 as shown in FIGS. 7 (b) and 8 (b). When it is entered, the white liquid and the packaged object are highlighted with white patterns and characters, which can be recognized as a display.
これによれば、消費者が充填スペース５を押圧しながら内縁シール部１０ａが剥離したことを目視によって確認することができ、安心して充填スペース５への押圧操作を行うことができる。しかも、図６に示す実施形態では、内縁シール部１０ａ位置のみならず、滞留部１２位置にも模様からなる印刷層７を設けたことで、液状被包装物が滞留部１２および注出通路部１３を通過する様子を目視で把握することができるため、液状被包装物が注出通路部１３から不測に飛び散る等の不安を抱くことがなくなる。さらに、例えば滞留部１２位置の印刷層７に、開封手順や注意喚起を表示させることもできるため、使い勝手がよくなる等の効果も期待できる。 According to this, the consumer can visually confirm that the inner edge seal portion 10a has peeled while pressing the filling space 5, and can perform the pressing operation on the filling space 5 with confidence. In addition, in the embodiment shown in FIG. 6, the printed layer 7 having a pattern is provided not only at the position of the inner edge seal portion 10a but also at the position of the retaining portion 12, so that the liquid packaged object retains the retaining portion 12 and the pouring passage portion. Since it is possible to visually grasp the state of passing through the liquid 13, it is possible to avoid anxiety that the liquid material to be packaged accidentally scatters from the pouring passage portion 13. Furthermore, for example, since the opening procedure and the reminder can be displayed on the printing layer 7 at the position of the retaining portion 12, it is possible to expect an effect that the usability is improved.
本発明の易剥離部の開封表示付包装袋および易剥離部の開封確認方法は、上記実施形態の四方シール形、三方シール形および背貼りシール形の包装袋のみならず、パウチやスタンディングパウチ、ガゼット袋、ピロー袋などの各種の包装袋に利用することができる。 The easy-peeling portion of the present invention is a packaging bag with an opening display and the method for confirming the opening of the easy-peeling portion is not only the four-sided sealing type, the three-sided sealing type and the back-sealed sealing type packaging bag, but also a pouch and a standing pouch, It can be used for various packaging bags such as gusset bags and pillow bags.
