Description

この発明は、表フィルムと裏フィルムをヒートシールして形成される包装袋に関するものである。   The present invention relates to a packaging bag formed by heat sealing a front film and a back film.

この種の包装袋は、袋口をヒートシールによって密封することができるため、各種食品や日用生活用品などの包装に広く利用されている。
ところで、両側辺にシール部を有し、上辺に袋口を形成した包装袋は、その形態から三方袋と呼ばれ、内容物を袋口から収容した後、袋口をヒートシールによって封印するようにして使用されている。
This type of packaging bag can be hermetically sealed by heat sealing, and thus is widely used for packaging various foods and daily necessities.
By the way, a packaging bag having a seal portion on both sides and having a bag mouth on the upper side is called a three-sided bag from its form, and after the contents are received from the bag mouth, the bag mouth is sealed by heat sealing. Has been used.

このような包装袋において、表フィルムと裏フィルムのシール部を易剥離性素材によって形成し、シール部の表フィルムと裏フィルムを反対方向に引っ張ってシール部を剥がして開封できるようにしたものがある。   In such a packaging bag, the seal part of the front film and the back film is formed of an easily peelable material, and the front part and the back film of the seal part are pulled in opposite directions so that the seal part can be peeled off and opened. is there.

また、包装袋の側辺に、ノッチと呼ばれる切り込みを入れ、このノッチ部分から表フィルムと裏フィルムの両方を引き裂いて開封するようにしたものもある。   There is also a type in which a notch called a notch is formed on the side of the packaging bag, and both the front film and the back film are torn and opened from the notch portion.

ところが、シール部を易剥離性素材によって形成し、シール部を引き剥がして開封できるようにした包装袋は、シール部が易剥離性といってもやはり力を入れてシール部を引き剥がす必要があり、女性や子供などの場合には、開封し難く、開封の際に、勢い余って内容物が飛び出したり、特に、スポンジケーキやゼリーのような軟らかい内容物の場合、型崩れさせたり、傷つけたりするおそれがある。   However, a packaging bag that is made of an easily peelable material and can be opened by peeling off the seal portion needs to peel off the seal portion with an effort even if the seal portion is said to be easily peelable. Yes, it is difficult for women and children to open, and the contents pop out excessively when opening, especially in the case of soft contents such as sponge cakes and jellies, they are out of shape or damaged. There is a risk of

一方、包装袋の側辺にノッチと呼ばれる切り込みを入れ、このノッチ部分から表フィルムと裏フィルムの両方を引き裂くようにした包装袋は、内容物としてピーナッツのような粒状体が詰め込まれているような場合には、ノッチ部分から上方部分を引き裂いて取り除くと包装袋の収納容積が小さくなるので、テーブルに横向きにおくと、開封した袋口から内容物がこぼれ出るおそれがあり、開封後、内容物が減るまでは、袋口を上にして内容物がこぼれないように持っていなければならない。   On the other hand, a notch called a notch is made on the side of the packaging bag, and both the front film and the back film are torn from this notch portion, and the contents are packed with granular materials such as peanuts. If the upper part is removed by tearing away the upper part from the notch part, the storage capacity of the packaging bag will be reduced.If placed sideways on the table, the contents may spill out from the opened bag mouth. Until the item is depleted, you must hold the bag mouth up so that the contents do not spill.

また、ノッチ部分から表フィルムと裏フィルムの両方を引き裂いてしまうと、例えば、裏フィルムに商品説明などを印刷してあるような場合には、上方の説明部分も切り取られてしまうので、説明部分が見づらくなるという問題もある。
そこで、この発明は、女性や子供でも開封しやすく、また、内容物がピーナッツのような粒状物であっても、開封した状態でテーブルにおいても内容物がこぼれ出ない包装袋を提供しようとするものである。
In addition, if both the front film and the back film are torn from the notch portion, for example, if a product description is printed on the back film, the upper explanation portion is also cut off, so the explanation portion There is also a problem that it becomes difficult to see.
Therefore, the present invention is intended to provide a packaging bag that can be easily opened even by women and children, and that the contents do not spill out even on the table even when the contents are granular, such as peanuts. Is.

この発明は、上記の課題を解決するために、表フィルムと裏フィルムをヒートシールして形成される包装袋において、表フィルムと裏フィルムのシール部を易剥離性素材によって形成し、かつ表フィルムと裏フィルムのシール部の少なくとも一箇所に、部分的に側縁から袋内部に向かって袋内部に到達しない未シール部を形成し、この未シール部に側縁から袋内部に向かって2条の切り目を形成し、この2条の切り目の間の表フィルムと裏フィルムを摘み片にしたのである。   In order to solve the above-described problems, the present invention provides a packaging bag formed by heat-sealing a front film and a back film, wherein a seal portion between the front film and the back film is formed of an easily peelable material, and the front film And an unsealed portion that does not reach the inside of the bag partially from the side edge toward the inside of the bag, and at least one portion of the sealing portion of the back film, and two strips from the side edge to the inside of the bag. The front film and the back film between the two cuts were picked into pieces.

このような構造の包装用袋においては、表フィルムと裏フィルムの未シール部に形成される摘み片の一方を摘んで引っ張って、未シール部の袋内部側に残ったシール部のみを引き剥がすことにより、開封が可能であるから、開封に余り力を要しない。   In the packaging bag having such a structure, one of the tabs formed on the unsealed portion of the front film and the back film is picked and pulled, and only the sealed portion remaining on the inside of the unsealed portion of the bag is peeled off. Therefore, since opening is possible, it does not require excessive force for opening.

また、表フィルムと裏フィルムに形成される摘み片の一方を摘んで引っ張ることにより、表フィルムと裏フィルムの一方だけを引き裂くことができるので、例えば、表フィルムだけを引き裂いて開封すれば、裏フィルムの印刷が切り取られることもない。   In addition, by picking and pulling one of the tabs formed on the front film and the back film, only one of the front film and the back film can be torn, so for example, if only the front film is torn and opened, The print on the film is not cut off.

この発明の包装袋としては、底部を表フィルムと裏フィルムの折り返しによって形成し、両側辺にシール部を形成し、上辺に袋口を形成した三方袋の形態がある。
また、底部の折り返しは、ガゼット折りにしてもよい。
As a packaging bag of this invention, there exists a form of the three-sided bag which formed the bottom part by folding | turning a front film and a back film, formed the sealing part on both sides, and formed the bag mouth in the upper side.
Further, the folding of the bottom portion may be a gusset fold.

この発明の包装袋を形成する表フィルムと裏フィルムとして、互いに離れる方向に反る性質が付与されたフィルムを使用すると、摘み片が互いに離れて摘み易くなる。   When a film imparted with a property of warping in a direction away from each other is used as the front film and the back film forming the packaging bag of the present invention, the tabs are separated from each other and are easily picked.

また、表フィルムと裏フィルムとして、開封方向に引き裂き易い方向性フィルムを使用すると、摘み片を持って引き裂く際に、切断片が途中で千切れ難く、開封し易い。ここで、開封方向に引き裂き易い方向性フィルムとは、主に一軸延伸フィルムのことであり、例えば、ユニチカ株式会社製のエンブレットPC(商品名)やエンブレットNC(商品名)、東レ株式会社製のトレファンBOYY22(商品名)、東洋化学株式会社製のカラリヤンY(商品名)などをいう。   In addition, when a directional film that is easily torn in the opening direction is used as the front film and the back film, the cut piece is difficult to tear in the middle and is easy to open when it is torn with the knob. Here, the directional film that is easy to tear in the opening direction is mainly a uniaxially stretched film, for example, Emblet PC (trade name) or Emblet NC (trade name) manufactured by Unitika Ltd., Toray Industries, Inc. It refers to TORAYFAN BOYY22 (trade name) manufactured by Toray Chemical Co., Ltd. and Karariyan Y (trade name) manufactured by Toyo Chemical Co., Ltd.

上記のように、この発明の包装袋は、余り力を入れなくてもシール部を引き剥がして容易に開封することができ、しかも、表フィルムと裏フィルムの一方を引き裂くことなく、一方だけを引き裂いて開封することができる。   As described above, the packaging bag of the present invention can be easily opened by tearing off the seal portion without applying excessive force, and only one of the front film and the back film is not torn. Can be torn and opened.

図1に示すこの発明の包装袋は、三方袋と呼ばれる形態の包装袋であり、表フィルム1aと裏フィルム1bの両側辺にヒートシールによって形成されるシール部2を有し、上辺が開口する袋口3に形成されている。   The packaging bag of this invention shown in FIG. 1 is a packaging bag of a form called a three-sided bag, and has seal portions 2 formed by heat sealing on both sides of the front film 1a and the back film 1b, and the upper side opens. It is formed in the bag mouth 3.

この包装袋の底部4は、表フィルム1aと裏フィルム1bの折り返しによって形成している。
上記シール部2は、易剥離性を有する素材によって形成されている。
ここで、易剥離性とは、ヒートシールによって密封することができ、開封時は接合された面々同士を容易に剥がすことができる性質のことであり、例えば、易剥離性のフィルムには、ジェイフィルム株式会社製のVMXフィルム(商品名)やIMXフィルム(商品名)がある。
この易剥離性を付与する手段としては、接合された面々同士が、界面剥離、層間剥離あるいは凝集剥離を起こす方法のいずれの方法を採用してもよい。
例えば、表フィルム1aと裏フィルム1bとして、基材フィルムの最内層にシーラント層を設けた積層フィルムで、最内層のシーラント層が、低密度ポリエチレン(LDPE)、直鎖状低密度ポリエチレン(L・LDPE)などの易剥離性フィルムで構成されたものを使用することができる。シーラント層の積層は、上記の樹脂をフィルム状に製膜し、ドライラミネーション法または押し出しラミネーション法で積層してもよく、また、上記の樹脂を押し出しコートして積層することもできる。
The bottom 4 of the packaging bag is formed by folding the front film 1a and the back film 1b.
The seal part 2 is formed of a material having easy peelability.
Here, the easy peelability is a property that can be sealed by heat sealing and can easily peel off the joined surfaces when opened. There are VMX film (trade name) and IMX film (trade name) manufactured by Film Corporation.
As a means for imparting such easy peelability, any method of causing interfacial peeling, delamination or cohesive peeling between the joined surfaces may be employed.
For example, as the front film 1a and the back film 1b, a laminated film in which a sealant layer is provided on the innermost layer of the base film, and the innermost sealant layer is made of low density polyethylene (LDPE), linear low density polyethylene (L What comprised the easily peelable film, such as LDPE, can be used. For the lamination of the sealant layer, the above resin may be formed into a film and laminated by a dry lamination method or an extrusion lamination method, or the above resin may be laminated by extrusion coating.

この発明の包装袋は、表フィルム1aと裏フィルム1bのシール部2の少なくとも一箇所に、部分的に側縁から袋内部に向かって袋内部に到達しない未シール部を形成し、この未シール部に側縁から袋内部に向かって2条の切り目5a、5bを形成し、この2条の切り目5a、5bの間の表フィルム1aと裏フィルム1bを摘み片6にしている。   The packaging bag according to the present invention forms an unsealed portion that does not reach the inside of the bag partially from the side edge toward the inside of the bag in at least one portion of the sealing portion 2 of the front film 1a and the back film 1b. Two cuts 5 a and 5 b are formed in the part from the side edge toward the inside of the bag, and the front film 1 a and the back film 1 b between the two cuts 5 a and 5 b are formed as a tab 6.

図1の包装袋では、上記摘み片6を、両側辺のシール部2の両方に形成しているが、片方のシール部2だけに形成してもよい。また、図1の包装袋では、摘み片6を包装袋の高さのほぼ中間に設けているが、袋口3、あるいは底部4に寄った位置に設けてもよい。   In the packaging bag of FIG. 1, the knob 6 is formed on both the seal portions 2 on both sides, but may be formed only on one seal portion 2. Further, in the packaging bag of FIG. 1, the knob 6 is provided at substantially the middle of the height of the packaging bag, but may be provided at a position close to the bag mouth 3 or the bottom 4.

この発明の包装袋は、表フィルム1aと裏フィルム1bの未シール部に形成される摘み片6の一方を摘んで引っ張って、未シール部の袋内部側に残ったシール部2のみを引き剥がすことにより、開封が可能であるから、開封に余り力を要しない。   The packaging bag of the present invention picks and pulls one of the tabs 6 formed on the unsealed portion of the front film 1a and the back film 1b, and peels only the seal portion 2 remaining on the bag inner side of the unsealed portion. Therefore, since opening is possible, it does not require excessive force for opening.

上記摘み片6を摘んで、表フィルム1aと裏フィルム1bを引き裂く際に、引き裂き片が途中で千切れないようにするために、表フィルム1aと裏フィルム1bを形成する基材フィルムは、開封方向に引き裂き性の良い方向性フィルムを使用することが好ましい。   The base film for forming the front film 1a and the back film 1b is opened in order to prevent the tear pieces from being broken in the middle when the pick piece 6 is picked to tear the front film 1a and the back film 1b. It is preferable to use a directional film having good tearability in the direction.

上記摘み片6を形成した表フィルム1aと裏フィルム1bが互いに密着していると、摘み片6が摘み難い。このため、上記表フィルム1aと裏フィルム1bとして、互いに離れる方向に反る性質が付与されたフィルムを使用することにより、図2に示すように、摘み片6が離れるので、摘み片6が摘み易くなる。
上記表フィルム1aと裏フィルム1bに互いに離れる方向に反る性質を付与する方法としては、例えば、表フィルム1aと裏フィルム1bを製造する際に、内面側を外面側よりも強く冷却することにより、互いに離れる方向に反る性質を付与することができる。
If the front film 1a and the back film 1b on which the knob 6 is formed are in close contact with each other, the knob 6 is difficult to pick. Therefore, as the front film 1a and the back film 1b, by using a film imparted with a property of warping in a direction away from each other, the knob 6 is separated as shown in FIG. It becomes easy.
As a method for imparting the properties of warping in the direction away from each other to the front film 1a and the back film 1b, for example, when manufacturing the front film 1a and the back film 1b, the inner surface side is cooled more strongly than the outer surface side. , The property of warping in the direction away from each other can be imparted.

この発明の包装袋は、袋口3から商品である内容物Aを収納し、図3(a)に示すように、袋口3をヒートシールにより封印することができる。符号7は、袋口3のシール部を示している。
そして、袋口3を閉じた包装袋は、図3(b)に示すように、表フィルム1aまたは裏フィルム1bに形成された摘み片6を摘んで引っ張り、摘み片6を構成する未シール部の袋内部側に残ったシール部2を引き剥がし、そのまま、図3(c)に示すように、摘み片6と共に、表フィルム1aまたは裏フィルム1bの一方を引き裂くことにより、容易に開封することができる。
The packaging bag of this invention accommodates the content A which is a product from the bag mouth 3, and can seal the bag mouth 3 by heat sealing as shown to Fig.3 (a). Reference numeral 7 denotes a seal portion of the bag mouth 3.
And the packaging bag which closed the bag mouth 3 picks and pulls the knob | pipe piece 6 formed in the surface film 1a or the back film 1b, and is shown in FIG.3 (b), The unsealed part which comprises the knob piece 6 As shown in FIG. 3 (c), the seal portion 2 remaining on the inner side of the bag is peeled off, and it is easily opened by tearing one of the front film 1a or the back film 1b together with the knob 6 Can do.

このように、この発明の包装袋は、表フィルム1aまたは裏フィルム1bの一方のみを引き裂いて開封できるので、ピーナッツのようなこぼれ出し易い内容物であっても、図3(c)に示すように、引き裂き面を上にしてそのままテーブルに置くことができ、下面の表フィルム1aまたは裏フィルム1bがお皿のような役割を果すので、衛生的で使用勝手が良い。   Thus, since the packaging bag of this invention can tear and open only one of the front film 1a or the back film 1b, even if it is the content which is easy to spill out like a peanut, as shown in FIG.3 (c). In addition, the tear film can be placed on the table as it is, and the front film 1a or the back film 1b on the lower surface plays a role like a plate, so it is hygienic and easy to use.

また、摘み片6による引き裂きを好みの所で止めることにより、内容物がこぼれないようにすることもできる。   Moreover, the content can also be prevented from spilling by stopping the tearing by the knob 6 at a desired position.

摘み片6による引き裂きを反対側のシール部2で止めることにより、摘み片6が内容物に混じらないので、異物混入の確認管理が容易である。   By stopping the tearing by the tab 6 at the seal portion 2 on the opposite side, the tab 6 is not mixed with the contents, so that it is easy to confirm and manage the contamination.
