Description

本発明は、詰替パウチ、及び詰替パウチの筒口部の取付け角度設定方法に係り、より詳細には、内容液を他の容器に詰め替える際に内容液を注出するための筒口部を備えた詰替パウチ、及びその筒口部の取付け角度設定方法に関する。 The present invention relates to the refill pouch and the method of setting the mounting angle of the cylinder mouth portion of the refill pouch, and more specifically, the cylinder mouth portion for pouring the content liquid when refilling the content liquid into another container is provided. The present invention relates to a refill pouch and a method for setting a mounting angle of the cylinder mouth portion thereof.

近年、詰替用の内容液を収容した軟質合成樹脂フィルム製のスタンディングパウチのような詰替パウチが広く利用されている。特に、複数回分の詰替用内容液として、詰替先の保形容器の容量の2倍以上の量の内容液が収容された大容量の詰替パウチが普及している。詰替パウチには、内容液をプラスチックボトル等の保形容器に移し替える際に内容液を注出するための筒口部(スパウト)が取り付けられている。 In recent years, a refill pouch such as a standing pouch made of a soft synthetic resin film containing a content liquid for refilling has been widely used. In particular, as a refilling content liquid for a plurality of times, a large-capacity refilling pouch containing a content liquid in an amount more than twice the capacity of the shape-retaining container at the refilling destination has become widespread. The refill pouch is equipped with a tube mouth (spout) for pouring out the content liquid when the content liquid is transferred to a shape-retaining container such as a plastic bottle.

一方、詰替パウチは、軟質合成樹脂フィルム製で柔らかいため、内容液が収容された状態で胴部を掴みにくい。特に、大容量の詰替パウチは重く、これを持ち上げると手指から滑りやすいため、内容液の詰替作業は容易ではない。
そこで、特許文献1には、肉厚片という簡易な構成を設けることによって、内容液を移し替える際に持ちやすくした詰替パウチが提案されている。
On the other hand, since the refill pouch is made of a soft synthetic resin film and is soft, it is difficult to grasp the body while the content liquid is contained. In particular, the large-capacity refill pouch is heavy, and when it is lifted, it slips easily from the fingers, so the refilling work of the content liquid is not easy.
Therefore, Patent Document 1 proposes a refill pouch that is easy to hold when the content liquid is transferred by providing a simple structure of a thick piece.

特開2018−118784号公報JP-A-2018-118784

ところで、詰替パウチから詰替先の保形容器に内容液を詰め替える際、注ぎ始めに、内容液が勢いよく飛び出して、こぼれてしまうことがある。特に、大容量の詰替パウチから詰め替える際には、詰替先の保形容器を床や台に置いたまま、詰替パウチを両手で持ち上げて傾ける必要があるため、詰替パウチの筒口部を詰替先の保形容器の口部に持って行く前に、内容液が勢いよく飛び出してしまうことが多い。
また、詰替先の保形容器が、スプレーボトルのように、略水平面内に開口した狭い口部を有している場合や、液だれ防止用のトランジッションキャップを備えない液体洗剤や柔軟剤の保形容器に詰め替える場合、詰替時に内容液がよりこぼれやすい傾向がある。
また、特に、内容液が、浴室用合成洗剤や液体消臭剤のように、水の粘度と同程度の低粘度の液体である場合には、詰替パウチの内容液が液体洗剤や柔軟剤のような高粘度の液体である場合に比べて、内容液がより勢いよく飛び出してしまう傾向がある。
By the way, when the content liquid is refilled from the refill pouch to the shape-retaining container at the refill destination, the content liquid may spill out vigorously at the beginning of pouring. In particular, when refilling from a large-capacity refill pouch, it is necessary to lift and tilt the refill pouch with both hands while keeping the shape-retaining container of the refill destination on the floor or table, so the cylinder mouth of the refill pouch must be tilted. In many cases, the content liquid rushes out before it is taken to the mouth of the shape-retaining container to be refilled.
Also, when the shape-retaining container of the refill destination has a narrow mouth opening in a substantially horizontal plane like a spray bottle, or for liquid detergents and fabric softeners that do not have a transition cap to prevent dripping. When refilling in a shape-retaining container, the content liquid tends to spill more easily during refilling.
In particular, when the content liquid is a liquid having a viscosity as low as that of water, such as synthetic detergents for bathrooms and liquid deodorants, the content liquid of the refill pouch is a liquid detergent or fabric softener. Compared with the case of a high-viscosity liquid such as, the content liquid tends to pop out more vigorously.

本発明は、上記の事情に鑑みてなされたものであり、内容液を移し替える際、注ぎ始めに内容液をこぼしにくい詰替パウチ、及び詰替パウチの筒口部の取付け角度設定方法を提供することを目的としている。 The present invention has been made in view of the above circumstances, and provides a refill pouch that does not easily spill the content liquid at the beginning of pouring when the content liquid is transferred, and a method for setting a mounting angle of the cylinder mouth portion of the refill pouch. The purpose is.

本出願に係る発明者は、種々の実験及び検討を重ねた結果、在来の詰替パウチでは、内容液を詰替パウチから詰替先の保形容器に詰め替える際、筒口部から内容液が注ぎ出始めた瞬間に、詰替パウチの筒口部が水平よりも上方を向いていると、内容液が勢いよく飛び出して、こぼれやすいことを見いだした。本発明は、かかる知見に基づいてなされたものである。 As a result of repeated experiments and studies, the inventor of the present application found that in a conventional refill pouch, when the content liquid is refilled from the refill pouch to the shape-retaining container of the refill destination, the content liquid is released from the cylinder mouth. At the moment when the pouring started, I found that if the tube mouth of the refill pouch was facing upward from the horizontal, the content liquid would pop out vigorously and easily spill. The present invention has been made based on such findings.

すなわち、上記の目的を達成するため、本発明の詰替パウチは、重ね合わせた表側フィルムと裏側フィルムとの間に形成された収容部と、前記表側フィルムと前記裏側フィルムの端縁に形成されたシール部と、前記収容部に収容された内容液を他の容器に詰め替える際に前記内容液を注出するために取り付けられた筒口部と、を備えた詰替パウチであって、詰替前の前記内容液の液面が前記筒口部の内部側開口の下端部と接するまで前記詰替パウチを傾けたとき、前記筒口部の外部側開口の下端部が前記内部側開口の下端部よりも低くなるように、前記筒口部が取り付けられていることを特徴としている。 That is, in order to achieve the above object, the refill pouch of the present invention is formed at the accommodating portion formed between the overlapped front side film and the back side film, and at the edge of the front side film and the back side film. A refill pouch having a seal portion and a cylinder mouth portion attached for pouring out the content liquid when refilling the content liquid contained in the storage portion into another container. When the refill pouch is tilted until the liquid level of the previous content liquid comes into contact with the lower end of the inner opening of the cylinder mouth, the lower end of the outer opening of the cylinder mouth is from the lower end of the inner opening. It is characterized in that the cylinder mouth portion is attached so as to be low.

また、本発明の詰替パウチの筒口部の取付け角度設定方法は、重ね合わせた表側フィルムと裏側フィルムとの間に形成された収容部と、前記表側フィルムと前記裏側フィルムの端縁に形成されたシール部と、前記収容部に収容された内容液を他の容器に詰め替える際に前記内容液を注出するために取り付けられた筒口部と、を備えた詰替パウチにおける前記筒口部の取付け角度を設定する方法であって、詰替前の前記内容液の液面が前記筒口部の内部側開口の下端と接するまで前記詰替パウチを傾けたとき、前記筒口部の外部側開口の下端部が前記内部側開口の下端部よりも低くなるように、前記筒口部の取付け角度を設定することを特徴としている。 Further, the method of setting the mounting angle of the cylinder mouth portion of the refill pouch of the present invention is formed on the accommodating portion formed between the overlapped front side film and the back side film and the edge edge of the front side film and the back side film. Attachment of the cylinder mouth portion in a refill pouch provided with a seal portion and a cylinder mouth portion attached for pouring out the content liquid when refilling the content liquid contained in the storage portion into another container. This is a method of setting an angle, and when the refill pouch is tilted until the liquid level of the content liquid before refilling comes into contact with the lower end of the inner side opening of the cylinder mouth portion, the lower end of the outer side opening of the cylinder mouth portion is tilted. It is characterized in that the mounting angle of the cylinder mouth portion is set so that the portion is lower than the lower end portion of the internal side opening.

本発明によれば、詰替前の内容液の液面が筒口部の内部側開口の下端部と接するまで詰替パウチを傾けたとき、筒口部の外部側開口の下端部が内部側開口の下端部よりも低くなるように、筒口部が取り付けられている。換言すれば、詰替パウチを傾けていって筒口部から内容液が注ぎ出始めた瞬間に、筒口部が水平よりも下方を向いているように、筒口部が取り付けられている。更に換言すれば、その瞬間に筒口部の根元から先端へ向かう軸線が水平に対して俯角をなすように、筒口部が取り付けられている。 According to the present invention, when the refill pouch is tilted until the liquid level of the content liquid before refilling comes into contact with the lower end of the inner opening of the cylinder mouth, the lower end of the outer opening of the cylinder mouth becomes the inner opening. The tube mouth is attached so that it is lower than the lower end. In other words, the cylinder mouth is attached so that the cylinder mouth faces downward from the horizontal at the moment when the refill pouch is tilted and the content liquid starts to be poured out from the cylinder mouth. In other words, the cylinder mouth portion is attached so that the axis from the root to the tip of the cylinder mouth portion forms a depression angle with respect to the horizontal at that moment.

これにより、筒口部から内容液が注ぎ出始めた瞬間に、内容液が上方に向かって飛び出すことが回避され、注ぎ始めに内容液をこぼしにくくすることができる。また、注ぎ始めに筒口部が水平よりも下方を向いているため、筒口部を詰替先の保形容器の口部に挿入しやすくなり、その結果、注ぎ始めに内容液をこぼしにくくすることができる。 As a result, it is possible to prevent the content liquid from jumping upward at the moment when the content liquid starts to be poured out from the cylinder mouth portion, and it is possible to prevent the content liquid from spilling at the beginning of pouring. In addition, since the cylinder mouth is facing downward from the horizontal at the beginning of pouring, it is easy to insert the cylinder mouth into the mouth of the shape-retaining container at the refill destination, and as a result, it is difficult to spill the contents liquid at the beginning of pouring. Can be done.

また、筒口部から内容液が注ぎ出始める直前に、筒口部が水平よりも上方を向いていると、筒口部の内部側開口が内容液によって塞がれ外部からの空気流入が遮断されることがある。そのため、内容液が注ぎ出始めた瞬間に、筒口部の内部を満たしていた内容液が一斉に勢いよく飛び出すことになる。
これに対し、本発明のように、筒口部から内容液が注ぎ出始めるときに、筒口部が水平よりも下方を向いていれば、筒口部内が内容液によって満たされていない。その結果、筒口部から内容液が注ぎ出始めた瞬間に、筒口部内を満たしていた内容液が一斉に勢いよく飛び出すことが回避されて、内容液がこぼれにくくなる。
In addition, if the cylinder mouth is facing upward from the horizontal just before the content liquid starts to be poured out from the cylinder mouth, the opening on the inner side of the cylinder mouth is blocked by the content liquid and the inflow of air from the outside is blocked. There is. Therefore, at the moment when the content liquid starts to be poured out, the content liquid that fills the inside of the cylinder mouth portion will burst out all at once.
On the other hand, as in the present invention, when the content liquid starts to be poured out from the cylinder mouth portion, if the cylinder mouth portion faces downward from the horizontal portion, the inside of the cylinder mouth portion is not filled with the content liquid. As a result, at the moment when the content liquid starts to be poured out from the cylinder mouth portion, it is avoided that the content liquid filling the inside of the cylinder mouth portion bursts out all at once, and the content liquid is less likely to spill.

本発明によれば、内容液を移し替える際、注ぎ始めに内容液をこぼしにくい詰替パウチ、及び詰替パウチの筒口部の取付け角度設定方法を提供することができる。 According to the present invention, it is possible to provide a refill pouch that does not easily spill the content liquid at the beginning of pouring when the content liquid is transferred, and a method for setting a mounting angle of the cylinder mouth portion of the refill pouch.

(在来の詰替パウチ)
まず、本発明の実施形態の説明に先立ち、図3及び図4を参照して、従来の詰替パウチを説明する。
図3に示す在来の詰替パウチ100は、スタンディングパウチであって、重ね合わせた表側フィルム101aと裏側フィルム101bとの間に形成された収容部102と、表側フィルム101aと裏側フィルム101bの端縁に形成されたシール部とを備えている。シール部としては、表側フィルム101aと裏側フィルム101bとをシールした、対向する2つのサイドシール部103及び104、及びトップシール部105と、表側フィルム101a及び裏側フィルム101bと底部のマチ部106とをシールしたボトムシール部107とが形成されている。
(Conventional refill pouch)
First, prior to the description of the embodiment of the present invention, the conventional refill pouch will be described with reference to FIGS. 3 and 4.
The conventional refill pouch 100 shown in FIG. 3 is a standing pouch, which is an accommodating portion 102 formed between the overlapped front side film 101a and the back side film 101b, and the edges of the front side film 101a and the back side film 101b. It has a sealing portion formed on the edge. As the sealing portion, two opposing side sealing portions 103 and 104 and a top sealing portion 105 that seal the front side film 101a and the back side film 101b, and the front side film 101a, the back side film 101b, and the bottom gusset portion 106 are provided. A sealed bottom seal portion 107 is formed.

詰替パウチ100では、2つのサイドシール部103及び104の一方のサイドシール部103とトップシール部105との出会うコーナー部分が、斜めに切り落とされて、サイドシール部103とトップシール部105との間を連絡する傾斜シール部108が形成されている。傾斜シール部108は、サイドシール部103に対して約45°傾斜している。 In the refill pouch 100, the corner portion where one of the two side seal portions 103 and 104 meets the top seal portion 105 is cut off diagonally, and the side seal portion 103 and the top seal portion 105 are combined. An inclined seal portion 108 is formed to connect the two. The inclined seal portion 108 is inclined by about 45 ° with respect to the side seal portion 103.

傾斜シール部108には、収容部102に収容された内容液を他の容器に詰め替える際に内容液を注出するために取り付けられた筒口部109が取り付けられている。筒口部109は、傾斜シール部108の外縁にほぼ直交するように設けられている。筒口部109はまた、筒口部109の内部側開口191が傾斜シール部108の内縁に位置するように配置されている。
なお、図3では、スクリューキャップ109aを筒口部109に螺合した開栓前の状態を示し、図4では、スクリューキャップ109aを外した状態を示す。
The inclined seal portion 108 is attached with a cylinder mouth portion 109 attached for pouring out the content liquid when the content liquid contained in the storage portion 102 is refilled into another container. The tube mouth portion 109 is provided so as to be substantially orthogonal to the outer edge of the inclined seal portion 108. The cylinder mouth portion 109 is also arranged so that the internal opening 191 of the cylinder mouth portion 109 is located at the inner edge of the inclined seal portion 108.
Note that FIG. 3 shows a state in which the screw cap 109a is screwed into the cylinder mouth portion 109 before opening, and FIG. 4 shows a state in which the screw cap 109a is removed.

ここで、図4に、在来の詰替パウチ100を、最初の詰替時に、内容液が注ぎ出る直前まで傾けた状態を示す。同図に示すように、このとき、詰替パウチ100の筒口部109の軸線Oは、内容液Cの液面cfに対して上方を向いている。同図では、この仰角をθeで表している。
換言すれば、内容液Cの液面cfの高さが、筒口部109の外部側開口192の下端部192aの高さとほぼ同じになるまで、詰替パウチ100を傾けたときに、筒口部109の外部側開口192が水平よりも上方を向いている。すなわち、筒口部109の外部側開口192の下端部192aの位置が、筒口部109の内部側開口191の下端部191aの位置よりも高くなっている。
Here, FIG. 4 shows a state in which the conventional refill pouch 100 is tilted until just before the content liquid is poured out at the time of the first refill. As shown in the figure, at this time, the axis O of the cylinder mouth portion 109 of the refill pouch 100 faces upward with respect to the liquid level cf of the content liquid C. In the figure, this elevation angle is represented by θe.
In other words, when the refill pouch 100 is tilted until the height of the liquid level cf of the content liquid C becomes almost the same as the height of the lower end portion 192a of the outer side opening 192 of the cylinder mouth portion 109, the cylinder mouth portion 109 The outer side opening 192 of the is facing upward from the horizontal. That is, the position of the lower end portion 192a of the outer side opening 192 of the cylinder mouth portion 109 is higher than the position of the lower end portion 191a of the inner side opening 191 of the cylinder mouth portion 109.

なお、実際には、詰替パウチ100を内容液Cが注ぎ出る直前まで傾けたときに、筒口部109の内部側開口191が内容液によって塞がれ外部からの空気流入が遮断されることがある。そのため、筒口部109が水平よりも上方を向いたまま、筒口部109から内容液Cが注ぎ出始めると、注ぎ始めに、筒口部109の内部を満たしていた内容液が一斉に勢いよく飛び出して、こぼしてしまうことが多い。
つまり、収容部2内の空気Aが、詰替パウチ100外部の空気とつながっていないため、外部から気体塊が筒口部109内部を満たしている内容液Cを押しのけて、筒口部109内に進入するのと入れ替えに、押し退けられた筒口部109内の内容液Cが勢いよく飛び出すことになる。
In reality, when the refill pouch 100 is tilted until just before the content liquid C is poured out, the internal opening 191 of the cylinder mouth portion 109 may be blocked by the content liquid to block the inflow of air from the outside. is there. Therefore, when the content liquid C starts to be poured out from the cylinder mouth portion 109 with the cylinder mouth portion 109 facing upward from the horizontal, the content liquid filling the inside of the cylinder mouth portion 109 bursts out all at once at the beginning of pouring. , Often spills.
That is, since the air A in the accommodating portion 2 is not connected to the air outside the refill pouch 100, the gas mass pushes away the content liquid C filling the inside of the cylinder mouth portion 109 from the outside and enters the cylinder mouth portion 109. Instead of doing so, the content liquid C in the cylinder mouth 109 that has been pushed out will pop out vigorously.

(本発明の実施形態による詰替パウチ)
次に、図1及び図2を参照して本発明の詰替パウチ及びその筒口部の取付け角度の設定方法の実施形態を説明する。
図1に示す詰替パウチ10は、スタンディングパウチであって、重ね合わせた表側フィルム1aと裏側フィルム1bとの間に収容部2を形成している。
表側フィルム1a及び裏側フィルム1bは、熱融着可能なシーラント層と基材層による積層フィルムにより構成されている。また、印刷層、接着層を設けることも可能である。
(Refill pouch according to the embodiment of the present invention)
Next, an embodiment of a method of setting a mounting angle of the refill pouch of the present invention and the cylinder mouth portion thereof will be described with reference to FIGS. 1 and 2.
The refill pouch 10 shown in FIG. 1 is a standing pouch, and a housing portion 2 is formed between the overlapped front side film 1a and the back side film 1b.
The front side film 1a and the back side film 1b are composed of a laminated film composed of a heat-sealing sealant layer and a base material layer. It is also possible to provide a printing layer and an adhesive layer.

表側フィルム1a及び裏側フィルム1bには、熱融着可能であれば、種々の材料及び構成を採用することができる。例えば、ナイロン、直鎖状ポリエチレン、低密度ポリエチレン、高密度ポリエチレン、ポリプロピレン等のポリオレフィン類、ポリエチレンテレフタレートなどのポリエステル類等の熱可塑性樹脂を挙げることができる。また、表側フィルム1a及び裏側フィルム1bは、バリア性フィルムであるアルミ蒸着フィルムや各種蒸着フィルム、又はアルミラミネートフィルムを挙げることができる。また、これらのプラスチックフィルムを単層で、或いは二種以上を積層して構成することができ、内容液に応じて適宜選択される。 Various materials and configurations can be adopted for the front side film 1a and the back side film 1b as long as they can be heat-sealed. For example, thermoplastic resins such as polyolefins such as nylon, linear polyethylene, low density polyethylene, high density polyethylene and polypropylene, and polyesters such as polyethylene terephthalate can be mentioned. Further, examples of the front side film 1a and the back side film 1b include an aluminum vapor deposition film which is a barrier film, various vapor deposition films, and an aluminum laminate film. Further, these plastic films can be formed by a single layer or by laminating two or more kinds, and are appropriately selected according to the content liquid.

また、表側フィルム1aと裏側フィルム1bの端縁にはシール部が形成されている。シール部としては、表側フィルム1aと裏側フィルム1bとをシールした、対向する2つのサイドシール部3及び4、及びトップシール部5と、表側フィルム1a及び裏側フィルム1bと底部のマチ部6とをシールしたボトムシール部7とが形成されている。 Further, a sealing portion is formed on the edge of the front side film 1a and the back side film 1b. As the sealing portion, two opposing side sealing portions 3 and 4 and a top sealing portion 5 that seal the front side film 1a and the back side film 1b, and a front side film 1a, a back side film 1b, and a bottom gusset portion 6 are provided. A sealed bottom seal portion 7 is formed.

詰替パウチ1では、2つのサイドシール部3及び4の一方のサイドシール部3とトップシール部5との出会うコーナー部分が、斜めに切り落とされ、サイドシール部3とトップシール部5との間を連絡する傾斜シール部8が形成されている。 In the refill pouch 1, the corner portion where one of the two side seal portions 3 and 4 meets the top seal portion 5 is cut off diagonally, and between the side seal portion 3 and the top seal portion 5. An inclined seal portion 8 is formed to connect the two.

傾斜シール部8には、収容部2に収容された内容液を他の容器に詰め替える際に内容液を注出するために取り付けられた筒口部9が取り付けられている。筒口部9は、その内部側開口91が傾斜シール部8の内縁8bに位置するように配置されている。
なお、図1では、スクリューキャップ9aを螺合した筒口部9を示し、図2では、スクリューキャップ9aを外した筒口部9を示す。
The inclined seal portion 8 is attached with a cylinder mouth portion 9 attached for pouring out the content liquid when the content liquid contained in the storage portion 2 is refilled into another container. The tube mouth portion 9 is arranged so that its internal opening 91 is located at the inner edge 8b of the inclined seal portion 8.
Note that FIG. 1 shows a cylinder mouth portion 9 in which the screw cap 9a is screwed, and FIG. 2 shows a cylinder mouth portion 9 in which the screw cap 9a is removed.

ここで、図2を参照して、詰替パウチ1の筒口部9の取り付け角度について説明する。本実施形態の詰替パウチ10では、詰替前の内容液Cの液面cfが筒口部9の内部側開口91の下端91aと接するまで詰替パウチ10を筒口部9側へ傾けたとき、筒口部9の外部側開口92の下端部92aの位置が内部側開口91の下端部91aの位置よりも低くなるように、筒口部9の取付け角度が設定されている。
換言すれば、最初の詰替時に、詰替パウチ10を内容液Cが注ぎ出る直前まで傾けたとき、筒口部9の軸線Oが、内容液Cの液面cfに対して下方を向いている。図2では、この角度をθcで表している。すなわち、内容液Cの液面cfの高さが、筒口部9の内部側開口91の下端部91aの高さとほぼ同じになるまで、詰替パウチ100を傾けたときに、筒口部109の外部側開口192が水平よりも下方を向いている。
Here, with reference to FIG. 2, the mounting angle of the cylinder mouth portion 9 of the refill pouch 1 will be described. In the refill pouch 10 of the present embodiment, when the refill pouch 10 is tilted toward the cylinder mouth portion 9 until the liquid level cf of the content liquid C before refilling comes into contact with the lower end 91a of the inner side opening 91 of the cylinder mouth portion 9. The mounting angle of the cylinder mouth portion 9 is set so that the position of the lower end portion 92a of the outer side opening 92 of the cylinder mouth portion 9 is lower than the position of the lower end portion 91a of the inner side opening 91.
In other words, at the time of the first refilling, when the refilling pouch 10 is tilted until just before the content liquid C is poured out, the axis O of the cylinder mouth portion 9 faces downward with respect to the liquid level cf of the content liquid C. .. In FIG. 2, this angle is represented by θc. That is, when the refill pouch 100 is tilted until the height of the liquid level cf of the content liquid C becomes substantially the same as the height of the lower end portion 91a of the inner side opening 91 of the cylinder mouth portion 9, the outside of the cylinder mouth portion 109 The side opening 192 faces downward from the horizontal.

これにより、筒口部9から内容液Cが注ぎ出始めた瞬間に、内容液Cが上方に向かって飛び出すことが回避され、注ぎ始めに内容液Cをこぼしにくくすることができる。また、注ぎ始めに筒口部9が水平よりも下方を向いているため、筒口部9を詰替先の保形容器の口部に挿入しやすくなり、その結果、注ぎ始めに内容液をこぼしにくくすることができる。
特に、本実施形態では、注出直前に筒口部9が水平よりも下方を向いているため、注出開始時に、筒口内部9が内容液Cで満たされておらず、収容部2内の空気Aと詰替パウチ10の外部の空気とが連通している。その結果、注出開始時に、筒口部9内において、筒口部9から流出する内容液Cと、外部から筒口部9内へ進入する空気とがそれぞれ筒口部9内を円滑に流通する。すなわち、注出開始時に、筒口部9内の下側を内容液Cが流れ、筒口部9内の上側を空気が流れる。これにより、注出開始時に、進入する空気によって筒口部9内の内容液Cが押し出されることが回避され、内容液Cが勢いよく飛び出すことを防止することができる。
As a result, it is possible to prevent the content liquid C from jumping upward at the moment when the content liquid C starts to be poured out from the cylinder mouth portion 9, and it is possible to prevent the content liquid C from spilling at the beginning of pouring. Further, since the cylinder mouth portion 9 faces downward from the horizontal at the beginning of pouring, it is easy to insert the cylinder mouth portion 9 into the mouth portion of the shape-retaining container at the refill destination, and as a result, it is difficult to spill the content liquid at the beginning of pouring. can do.
In particular, in the present embodiment, since the cylinder mouth portion 9 faces downward from the horizontal immediately before pouring, the inside of the cylinder mouth portion 9 is not filled with the content liquid C at the start of pouring, and the air in the accommodating portion 2 A and the air outside the refill pouch 10 are in communication with each other. As a result, at the start of pouring, the content liquid C flowing out from the cylinder mouth portion 9 and the air entering the cylinder mouth portion 9 from the outside smoothly circulate in the cylinder mouth portion 9, respectively. That is, at the start of pouring, the content liquid C flows on the lower side in the cylinder mouth portion 9, and air flows on the upper side in the cylinder mouth portion 9. As a result, it is possible to prevent the content liquid C in the cylinder mouth portion 9 from being pushed out by the invading air at the start of pouring, and to prevent the content liquid C from rushing out.

筒口部9の取り付け角度は、詰替パウチ10に充填される内容液Cの液面cfの高さによって決まる。したがって、詰替パウチ10に充填される内容液Cの量が多いほど、筒口部9の取り付け角度、例えば、詰替パウチ10を傾けずに正置したときの鉛直線である、サイドシール部3の外縁3aの仮想延長線L1と、筒口部9の軸線Oとの成す角度θaを大きく設定する必要がある。
また、詰替パウチ10を傾けないときの内容液Cの液面cfの高さが、筒口部9の内部側開口91の下端部91aの高さに近い場合には、本実施形態の詰替パウチ10では、図1及び図2に示したような在来の詰替パウチ100の筒口部109の取り付け角度よりも、水平に対する傾斜角度を大きくする設定されることが多い。
なお、詰替パウチ10を傾けないときの内容液Cの液面cfの高さは、筒口部9の内部側開口91の下端部91aの高さよりも低いことが望ましい。
The mounting angle of the cylinder mouth portion 9 is determined by the height of the liquid level cf of the content liquid C filled in the refill pouch 10. Therefore, the larger the amount of the content liquid C filled in the refill pouch 10, the more the mounting angle of the cylinder mouth portion 9, for example, the vertical line when the refill pouch 10 is placed upright without tilting, the side seal portion 3 It is necessary to set a large angle θa formed by the virtual extension line L1 of the outer edge 3a of the above and the axis O of the cylinder mouth portion 9.
Further, when the height of the liquid level cf of the content liquid C when the refill pouch 10 is not tilted is close to the height of the lower end portion 91a of the inner side opening 91 of the cylinder mouth portion 9, the refilling of the present embodiment is performed. In the pouch 10, the inclination angle with respect to the horizontal is often set to be larger than the attachment angle of the cylinder mouth portion 109 of the conventional refill pouch 100 as shown in FIGS. 1 and 2.
It is desirable that the height of the liquid level cf of the content liquid C when the refill pouch 10 is not tilted is lower than the height of the lower end portion 91a of the inner side opening 91 of the cylinder mouth portion 9.

また、本実施形態の詰替パウチ10の筒口部9は、図1に示すように、サイドシール部3の外縁3aの仮想延長線L1と、トップシール部5の外縁5aの仮想延長線L2と、傾斜シール部8の外縁8aとで囲まれた領域に収まるように、傾斜シール部8に取り付けられている。さらに、筒口部9にスクリューキャップ9aを取り付けた状態で、上記の囲まれた領域に収まることがより好ましい。
これにより、筒口部9の取り付け角度が在来のものと異なっていても、筒口部9が邪魔にならない。その結果、詰替パウチ10の梱包及び陳列を,在来のものと同様に効率よく行うことができる。
Further, as shown in FIG. 1, the cylinder mouth portion 9 of the refill pouch 10 of the present embodiment has a virtual extension line L1 of the outer edge 3a of the side seal portion 3 and a virtual extension line L2 of the outer edge 5a of the top seal portion 5. , It is attached to the inclined seal portion 8 so as to fit in the area surrounded by the outer edge 8a of the inclined seal portion 8. Further, it is more preferable that the screw cap 9a is attached to the tube mouth portion 9 and fits in the enclosed area.
As a result, even if the mounting angle of the cylinder mouth portion 9 is different from that of the conventional one, the cylinder mouth portion 9 does not get in the way. As a result, the refill pouch 10 can be packed and displayed as efficiently as the conventional one.

また、図1において、サイドシール部3の外縁3aの仮想延長線L1と筒口部9の軸線Oとの成す角度θaが大きくなるほど、筒口部9が取り付けられる傾斜シール部8の外縁8aに対するサイドシール部3の外縁3aの傾斜角度θbを小さくする必要がある。
しかし、仮想延長線L1及びL2よりも内側に筒口部9を収納しつつ、傾斜角度θbを小さくするほど、サイドシール部3とトップシール部5とが出会うコーナーが大きく切り取られることになる。このため、切り取られるコーナーが大きくなりすぎて、詰替パウチ10の容量が小さくなることを回避するため、傾斜角度θbは、10°以上であることが好ましい。
Further, in FIG. 1, the larger the angle θa formed by the virtual extension line L1 of the outer edge 3a of the side seal portion 3 and the axis O of the cylinder mouth portion 9, the larger the side seal with respect to the outer edge 8a of the inclined seal portion 8 to which the cylinder mouth portion 9 is attached. It is necessary to reduce the inclination angle θb of the outer edge 3a of the portion 3.
However, as the inclination angle θb is reduced while the cylinder mouth portion 9 is housed inside the virtual extension lines L1 and L2, the corner where the side seal portion 3 and the top seal portion 5 meet is cut out larger. Therefore, the inclination angle θb is preferably 10 ° or more in order to prevent the cut corner from becoming too large and reducing the capacity of the refill pouch 10.

なお、本実施形態では、サイドシール部3、4、及びトップシール部5は帯状の一定幅を有する。このため、サイドシール部3の外縁3aと内縁3bとは平行であり、サイドシール部4の外縁4aと内縁4bも平行であり、トップシール部5の外縁5aと内縁も平行である。また、傾斜シール部8の外縁8aと内縁8bも平行である。 In the present embodiment, the side seal portions 3, 4 and the top seal portion 5 have a band-shaped constant width. Therefore, the outer edge 3a and the inner edge 3b of the side seal portion 3 are parallel, the outer edge 4a and the inner edge 4b of the side seal portion 4 are also parallel, and the outer edge 5a and the inner edge of the top seal portion 5 are also parallel. Further, the outer edge 8a and the inner edge 8b of the inclined seal portion 8 are also parallel.

また、詰替パウチ10の横幅が広いほど、詰替パウチ10の傾きを変えたときの筒口部9付近での内容液Cの液面cfの上下変動幅が大きくなり、詰替パウチ10を傾けて筒口部9から内容液Cを注ぐときに、内容液Cが勢いよく出やすくなる。
このため、図1に示す、対向する2つのサイドシール部3,4の間隔W、すなわち、一方のサイドシール部3の内縁3bから他方のサイドシール部4の内縁4bまでの距離Wは、250mm以下であることが好ましい。距離Wを250mm以下とすることにより、詰め替える際、内容液が勢いよく飛び出して、こぼれてしまうことのより一層の抑制は図ることができる。
Further, the wider the width of the refill pouch 10, the larger the vertical fluctuation width of the liquid level cf of the content liquid C in the vicinity of the cylinder mouth portion 9 when the inclination of the refill pouch 10 is changed, and the refill pouch 10 is tilted. When the content liquid C is poured from the cylinder mouth portion 9, the content liquid C tends to come out vigorously.
Therefore, the distance W between the two opposing side seal portions 3 and 4, that is, the distance W from the inner edge 3b of one side seal portion 3 to the inner edge 4b of the other side seal portion 4 shown in FIG. 1 is 250 mm. The following is preferable. By setting the distance W to 250 mm or less, it is possible to further suppress the content liquid from spilling out vigorously when refilling.

また、内容液Cが、注ぎ出しの感覚が略水と同等の1〜200mPa・sの粘度を有する液体である場合には、内容液Cが、シャンプーやリンスのような数千mPa・s以上の粘度を有する液体である場合よりも、詰替時に勢いよく飛び出しやすい。このため、本発明は、浴室用合成洗剤や液体消臭剤のように水の粘度と同程度の、1〜200mPa・sの粘度の低い内容液Cを詰め替える場合に適用してより好適である。 Further, when the content liquid C is a liquid having a viscosity of 1 to 200 mPa · s, which is equivalent to that of water, the content liquid C is several thousand mPa · s or more such as shampoo or rinse. It is easier to pop out vigorously at the time of refilling than when it is a liquid having the viscosity of. Therefore, the present invention is more suitable for refilling a content liquid C having a low viscosity of 1 to 200 mPa · s, which has the same viscosity as water, such as a synthetic detergent for bathrooms and a liquid deodorant. ..

また、複数回分の詰替用内容液として、詰替先の保形容器の容量の2倍以上の量の内容液が収容された大容量の詰替パウチは重く、これを持ち上げると手指から滑りやすいため、内容液の詰替作業は容易ではない。このため、本発明は、収容部2は、大容量である400〜4000mLの容量を有する詰替パウチに適用して好適である。 In addition, a large-capacity refill pouch containing more than twice the capacity of the refillable shape-retaining container as the content liquid for multiple refills is heavy, and when it is lifted, it slips from the fingers. Since it is easy, the refilling work of the content liquid is not easy. Therefore, in the present invention, the accommodating portion 2 is suitable for application to a refill pouch having a large capacity of 400 to 4000 mL.

ここで、本発明の実施例を説明する。本実施例で使用したパウチ及び内容液の条件は、以下の通りである。

In this embodiment, the depression angle from the horizontal to the downward of the mouthpiece when the content liquid first starts to come out is set variously. The depression angle at this time is substantially the same as the depression angle when the refill pouch is tilted until the liquid level of the content liquid before refilling comes into contact with the lower end of the inner opening of the cylinder mouth portion.
Then, it was determined whether or not the eight subjects were refilled without spilling into the refill destination bottle according to the horizontal to downward depression angle of the mouthpiece when the content liquid started to be poured out. Judgment was made based on the following criteria, and the average of 8 people was taken. X: less than 2 points, Δ: 2 points or more and less than 3 points, 〇: 3 points or more.
5 points: I hardly feel anxiety about spilling.
4 points: There is not much anxiety about spilling. There is a feeling of spilling very carelessly.
3 points: If you pour it carefully, it will not spill. There is a feeling of spilling if you are not careful.
2 points: I feel that I will not spill if I pour it with great care.
1 point: Actually spilled.
The results are shown in Table 1.
