又、上記バッグインボックス用内袋に食品を充填し、容易に取り出す方法に関するものである。
【０００２】
【従来の技術】
従来、味噌、あんこ、フラワーペースト等の粘稠な食品、或いは、バター、マーガリン、ショートニング等の充填時には液状であるが取り出し時には固化している食品等を容易に取り出すことができるバッグインボックス用内袋としては、外層袋の中に内層袋が挿入された２重袋で、重ね合わされた両開口部近傍で外層袋の内面と内層袋の外面とが接合された袋が知られている。例えば、実公昭３７−３０１９５号公報、特開昭６２−１２２９２２号公報、更には、特許２７３３１８３号等に開示されている。
【０００３】
更に、内容物の充填をスパウトより行い、内容物の取り出しは開口部より行うスパウト付きのバッグインボックス用内袋が知られている。特に、スパウト付きのバッグインボックス用内袋は、充填時に液状体である内容物を充填させるのに好適である。
尚、これらの袋から内容物を取り出す際には、袋を上下逆さにして内容物を落下させると共に、内容物と密着している内層袋を引き出して外層袋の内面と内層袋の外面との接合部を支点として反転させる。
【０００４】
しかし、スパウト付きのバッグインボックス用内袋を上下逆さにして内容物の落下と共に内層袋を引き出すと、スパウトの取り付け場所が内層袋を反転させる時の支点となる。即ち、袋に取り付けられたスパウトの外周で、袋の中央側が支点となる。
スパウトの取り付けられた所が内層袋を反転させる時の支点になると、内容物を取り出す際に、その部分にスパウトと内層袋を引き裂く力が集中し、破袋を生じさせていた。
【０００５】
【発明が解決しようとする課題】
本発明は、スパウト付きの２重袋において、内層袋を引き出して内容物を取り出す際に、スパウトの取り付け部より内層袋の破袋を生じさせないバッグインボックス用内袋を提供しようとするものである。
又、バッグインボックス用内袋に充填された食品を容易に取り出す方法を提供しようとするものである。
【０００６】
【課題を解決するための手段】
本発明は、上記課題を解決するために次のような手段を講じた。即ち、外層袋の中に内層袋が挿入され、内容物の取り出し用の開口部近傍で外層袋の内面と内層袋の外面とが接合され、この接合された位置よりも開口部側において内層袋が密封され、内層袋を反転させて内容物を取り出すバッグインボックス用内袋において、外層袋と内層袋の片方の面を貫通してスパウトが装着され、外層袋のスパウト周囲に易切断部を設ける。好ましくは、外層袋のスパウト周囲に施された易切断部を、ミシン目状の切断部とする。更に、上記スパウト付きバッグインボックス用内袋に、充填時には液状で取り出し時には固化する食品を、前記スパウトから充填し、取り出す際は、前記内層袋の密封を開封し、前記内層袋を反転させて固化した食品を取り出す。好ましくは、食品が、マーガリン、ファットスプレッド、ショートニング、バター、フラワーペースト、チーズ、チョコレート用油脂、ラード、牛脂、パーム油、ヤシ油またはパーム核油である。
【０００７】
【発明の実施態様】
本発明の内層袋の反転が容易なスパウト付きバッグインボックス用内袋に用いられるプラスチックフィルムとしては、従来、バッグインボックス用内袋に使用されているプラスチックフィルムを使用することができる。例えば、直鎖状低密度ポリエチレン樹脂等のポリエチレン系樹脂からなるフィルムが好適に用いられる。又、強度や安全性等の面から複数枚のフィルムを重ね合わせたものが好ましい。更に、ガス遮断性樹脂層等の特殊機能を有する樹脂層を設けた積層フィルム等も好適に使用される。

尚、外層袋の中に内層袋を挿入させるには、完成した外層袋と内層袋を用いることができるが、袋を製袋する工程で、外層袋の中に内層袋が挿入された状態に製袋することもできる。しかし、開口部近傍の外層袋の外面と内層袋の外面の接合も完成した内層袋を外層袋の中に挿入させてから行うこともできるが、袋を製袋する工程で、外層袋の内面と内層袋の外面とが接合された状態に製袋することもできる。
【００１２】
バッグインボックス用内袋にスパウトを取り付けるには、外層袋に内層袋を挿入させてから、外層袋と内層袋の所定位置を削孔し、該孔にスパウトを貫通させて熱融着により取り付けることができる。又、袋を製袋する工程で、外層袋用や内層袋用のフィルムにスパウトの取り付け用孔を削孔し、外層袋の中に内層袋が挿入された状態で、しかも、スパウトが取り付けられた状態で製袋することもできる。
【００１３】
そして、本発明の内層袋の反転が容易なスパウト付きバッグインボックス用内袋は、内層袋の開口部が密封されている。しかも、内層袋の開口部が密封されている位置は、外層袋の内面と内層袋の外面とが接合された位置よりも開口部の縁部よりの位置である。
【００１４】
又、本発明の内層袋の反転が容易なスパウト付きバッグインボックス用内袋は、内層袋の開口部がテープ状層間易剥離材を介在させて密封されていてもよい。即ち、内層袋の片方の内面にテープ状層間易剥離材の片方のヒートシール層を、内層袋のもう一方の内面にテープ状層間易剥離材のもう一方のヒートシール層を接着させて密封させる。
【００１５】
テープ状層間易剥離材としては、特開平６−２８６７５７号公報や特開平６−３２３５９号公報に記載されているテープ状層間易剥離材が使用されている。即ち、熱融着可能なヒートシール層を両最外層とし、手で剥離可能な剥離層を芯層とするテープ状層間易剥離材を使用する。尚、両最外層のヒートシール層と芯層の易剥離層との間には、耐熱性等に優れた基材層等を設けたものが好ましい。又、芯層の易剥離層は、比較的接着強度の弱い樹脂からなる部分的な樹脂層と接着剤や粘着剤からなる層を積層させたものが用いられる。更に、開封時に両最外層等が把手となるように、両最外層等の一方の端を残して芯層の剥離層を積層させているものが好ましい。
【００１６】
更に、本発明の内層袋の反転が容易なスパウト付きバッグインボックス用内袋は、スパウト周囲の外層袋に易切断部が設けられていることを最大の特徴とする。
スパウトの周囲とは、スパウトに隣接した周囲からスパウトより１００ｍｍ程度離れた位置の周囲までを意味する。又、スパウトの周囲は、円形状であっても、矩形状であってもよい。
【００１７】
又、易切断部とは、他の場所よりも切断され易い状態になっていれば、その形状については特に限定されるものではないが、一般的には、ミシン目状の切断部を有する形状が好ましい。しかも、そのミシン目は１本のみならず、複数本設けられていてもよい。
【００１８】
本発明の内層袋の反転が容易なスパウト付きバッグインボックス用内袋から、内容物を取り出す方法について説明する。
まず、バッグインボックス用内袋の開口部に設けられた密封部を切断、或いは、テープ状層間易剥離材を剥離させて開封する。尚、密封部を切断する際に、外層袋の内面と内層袋の外面との接合部分を切り離さないようにする必要がある。
【００１９】
次に、バッグインボックス用内袋を上下逆さにし、内容物を自重により内層袋と共に落下させる。その際、内容物の自重により外層袋に施されたスパウト周囲の易切断部が切断され、スパウトは外層袋から分離し、内層袋に付着した状態になる。そして、スパウトの付着した内層袋は引き出され、層袋の内面と内層袋の外面との接合部を支点にして反転される。そして、反転された内層袋の内面から内容物を剥離させて取り出す。特に、内容物が、食品、特にマーガリン、ファットスプレッド、ショートニング、バター、フラワーペースト、チーズ、チョコレート用油脂、ラード、牛脂、パーム油、ヤシ油またはパーム核油の場合、容易に取り出すことができる。又、内容物が固形物である場合には、内容物を一つの塊として取り出すことができる。

図１は、内層袋の反転が容易なスパウト付きバッグインボックス用内袋の概略平面図である。図２は、内容物を取り出す状態を示す説明図である。
【００２１】
外層袋（１）の中に内層袋（２）が挿入され、しかも、外層袋の開口部と内層袋の開口部が重ね合わされている。
そして、内層袋の開口部が密封（３）されていると共に、スパウト（４）が開口部の近傍に取り付けられている。更に、スパウト（４）の周囲の外層袋（１）に１本のミシン目状の切断部からなる易切断部（５）が施されている。
【００２２】
【作用】
本発明の内層袋の反転が容易なスパウト付きバッグインボックスは、スパウト周囲の外層袋に易切断部が施されているので、内容物と共に内層袋を引き出される際に外層袋の該易切断部が切断し、内層袋がスパウトを付けた状態で引き出される。そして、外層袋の内面と内層袋の外面との接合部が支点となり、内層袋が反転されるので、スパウトがり付けられた場所等の荷重が掛かるようなことがなくなる。
そのため、内容物を取り出す際に、スパウトが取り付けられた内層袋の部分より破袋が生じることがない。

[0007]
DETAILED DESCRIPTION OF THE INVENTION
As the plastic film used for the inner bag for a bag-in-box with a spout that allows easy reversal of the inner-layer bag of the present invention, a plastic film conventionally used for an inner bag for a bag-in-box can be used. For example, a film made of a polyethylene resin such as a linear low density polyethylene resin is preferably used. Moreover, what laminated | stacked the several sheets of film from surfaces, such as intensity | strength and safety | security, is preferable. Furthermore, a laminated film provided with a resin layer having a special function such as a gas barrier resin layer is also preferably used.
[0008]
In addition, as the shape of the outer layer bag or the inner layer bag used for the bag-in-box inner bag with a spout that allows easy reversal of the inner-layer bag of the present invention, the shape of the shape conventionally used as an inner bag for a bag-in box Can be used. For example, a rectangular bag-shaped body, a bag-shaped body having a square bottom seal portion, or the like is used. In addition, the outer layer bag and the inner layer bag do not necessarily have the same shape, but preferably the openings have the same shape.
In particular, it is preferable that the outer bag and the inner bag are rectangular bags that are both heat-sealed because they are inexpensive and excellent in strength.
[0009]
And the spout is attached to the inner bag for bag-in-boxes of this invention.
The shape of the spout is not particularly limited, and a spout that has been conventionally used for injection ports of liquids and viscous materials can be used.
Also, the method of attaching the spout is not particularly limited, and a spout attached by a conventional method can be used. For example, a spout that is attached through one surface of the outer layer bag and the inner layer bag and is heat-sealed to the plastic film of both bags is preferably used.
[0010]
Furthermore, the position where the spout is attached to the inner bag for the bag-in-box of the present invention is preferably a position close to the opening because the contents are dropped together with the inner layer bag from the opening. Specifically, it is preferable to place 20 to 100 mm from the opening of the inner bag for bag-in-box to the center of the bag. If the spout attachment location is too adjacent to the opening of the inner bag for the bag-in-box, it becomes difficult to cut the sealing portion leaving the joint between the inner surface of the outer bag and the outer surface of the inner bag. There is a case.
[0011]
In the inner bag for a spout-equipped bag-in-box according to the present invention, the inner bag is inserted into the outer bag, and the opening of the outer bag and the opening of the inner bag are overlapped. The inner surface of the outer layer bag and the outer surface of the inner layer bag are joined between the opening edge and the spout near the opening of the outer layer bag and the inner layer bag. Generally, the inner surface of the outer layer bag and the outer surface of the inner layer bag are bonded by heat sealing.
In order to insert the inner layer bag into the outer layer bag, the completed outer layer bag and inner layer bag can be used, but in the step of making the bag, the inner layer bag is inserted into the outer layer bag. You can also make bags. However, the outer surface of the outer layer bag in the vicinity of the opening and the outer surface of the inner layer bag can also be joined after inserting the completed inner layer bag into the outer layer bag. And the outer surface of the inner layer bag can be joined together.
[0012]
To attach a spout to an inner bag for a bag-in-box, insert the inner layer bag into the outer layer bag, then drill a predetermined position between the outer layer bag and the inner layer bag, and attach the spout through the hole and attach it by thermal fusion. be able to. Also, in the process of making the bag, the spout attachment hole is drilled in the film for the outer layer bag or the inner layer bag, and the spout is attached with the inner layer bag inserted into the outer layer bag. It is also possible to make a bag in a heated state.
[0013]
And the opening part of an inner layer bag is sealing the inner bag for bag-in-boxes with a spout in which the inversion of the inner layer bag of this invention is easy. And the position where the opening part of the inner layer bag is sealed is a position from the edge part of an opening part rather than the position where the inner surface of the outer layer bag and the outer surface of the inner layer bag were joined.
[0014]
In the inner bag for a spout-equipped bag-in-box with which the inner layer bag of the present invention can be easily reversed, the opening of the inner layer bag may be sealed with a tape-like delamination material interposed. That is, one heat seal layer of the tape-like interlayer peelable material is bonded to one inner surface of the inner layer bag, and the other heat seal layer of the tape-like interlayer peelable material is bonded to the other inner surface of the inner layer bag and sealed. .
[0015]
As the tape-like delamination material, tape-like delamination materials described in JP-A-6-286757 and JP-A-6-32359 are used. In other words, a tape-like easily peelable material having heat sealable heat seal layers as both outermost layers and a manually peelable release layer as a core layer is used. In addition, it is preferable that a base material layer having excellent heat resistance or the like is provided between the heat seal layers of both outermost layers and the easily peelable layer of the core layer. Further, as the easily peelable layer of the core layer, a layer in which a partial resin layer made of a resin having a relatively weak adhesive strength and a layer made of an adhesive or a pressure-sensitive adhesive are laminated is used. Further, it is preferable that the core layer release layer is laminated except for one end of both outermost layers so that both outermost layers become grips when opened.
[0016]
Furthermore, the inner bag for a bag-in-box with a spout that allows easy reversal of the inner layer bag of the present invention is characterized in that an easily cut portion is provided in the outer layer bag around the spout.
The periphery of the spout means from the periphery adjacent to the spout to the periphery of a position about 100 mm away from the spout. Further, the periphery of the spout may be circular or rectangular.
[0017]
In addition, the easy-cutting part is not particularly limited as long as it is in a state where it can be cut more easily than other places, but in general, a shape having a perforated cutting part. Is preferred. Moreover, not only one perforation but also a plurality of perforations may be provided.
[0018]
A method for taking out the contents from the inner bag for a bag-in-box with a spout, in which the inner layer bag of the present invention can be easily reversed, will be described.
First, the sealing part provided in the opening part of the inner bag for bag-in-box is cut | disconnected or a tape-shaped interlayer easily peelable material is peeled, and it opens. When cutting the sealing portion, it is necessary not to separate the joint portion between the inner surface of the outer layer bag and the outer surface of the inner layer bag.
[0019]
Next, the bag-in-box inner bag is turned upside down, and the contents are dropped together with the inner layer bag by its own weight. At that time, the easy-cut portion around the spout applied to the outer layer bag is cut by the weight of the contents, and the spout is separated from the outer layer bag and is attached to the inner layer bag. Then, the inner layer bag to which the spout is attached is pulled out and inverted with the joint portion between the inner surface of the layer bag and the outer surface of the inner layer bag as a fulcrum. Then, the contents are peeled off from the inner surface of the inverted inner layer bag and taken out. In particular, if the content is a food, particularly margarine, fat spread, shortening, butter, flour paste, cheese, chocolate oil, lard, beef tallow, palm oil, coconut oil or palm kernel oil, it can be easily removed. When the content is a solid, the content can be taken out as one lump.
[0020]
Hereinafter, an example of an inner bag for a bag-in-box with a spout in which the inner layer bag of the present invention can be easily reversed will be described with reference to the drawings.
FIG. 1 is a schematic plan view of an inner bag for a bag-in-box with a spout in which the inner layer bag can be easily reversed. FIG. 2 is an explanatory view showing a state in which the contents are taken out.
[0021]
The inner layer bag (2) is inserted into the outer layer bag (1), and the opening of the outer layer bag and the opening of the inner layer bag are overlapped.
And the opening part of the inner-layer bag is sealed (3), and the spout (4) is attached in the vicinity of the opening part. Furthermore, the easily cut part (5) which consists of one perforated cut part is given to the outer-layer bag (1) around a spout (4).
[0022]
[Action]
The bag-in-box with a spout that allows easy reversal of the inner-layer bag of the present invention has an easy-cut portion on the outer-layer bag around the spout, so that when the inner-layer bag is pulled out together with the contents, Is cut out and the inner layer bag is pulled out with a spout attached. The joint between the inner surface of the outer layer bag and the outer surface of the inner layer bag serves as a fulcrum, and the inner layer bag is inverted, so that a load such as a place where the spout is attached is not applied.
Therefore, when taking out the contents, bag breakage does not occur from the portion of the inner layer bag to which the spout is attached.
[0023]

The inner bag for the spout-equipped bag-in-box with which the inner bag was easily inverted was filled with 15 kg of fluid margarine from the spout and left for 2 days.
In order to take out the margarine filled in the inner bag for the bag-in-box, first, the sealed portion by heat sealing applied to the opening of the inner layer bag was cut off and opened. And the inner bag for bag-in-boxes was turned upside down, the inner layer bag was pulled out together with the solidified margarine, and the inner layer bag was inverted. At that time, the spout was separated from the outer layer bag and pulled out together with the inner layer bag. Then, the inner layer bag was inverted using the joint portion between the inner surface of the outer layer bag and the outer surface of the inner layer bag as a fulcrum.
And the margarine solidified from the inner surface of the inverted inner layer bag was peeled off and taken out.
