Description

本発明は、封止区域によって区切られた注ぎ口が包装袋の頂部区域に形成された、注ぎ口付き包装袋に関する。   The present invention relates to a packaging bag with a spout, in which a spout delimited by a sealing area is formed in the top area of the packaging bag.

近年、プラスチックボトルなどの主要容器に格納された、少量の液体などの内容物が取り出され、使用される際、主要容器の内容物が使い果たされても主要容器は廃棄されるよりは、新しい内容物が再充填されて主要容器が再利用される。包装袋の頂部に注ぎ口を有する注ぎ口付き包装袋は、再充填用内容物を格納する包装袋として使用される。   In recent years, when contents such as a small amount of liquid stored in a main container such as a plastic bottle are taken out and used, even if the main container is used up, the main container is discarded. New contents are refilled and the main container is reused. A packaging bag with a spout having a spout at the top of the packaging bag is used as a packaging bag for storing contents for refilling.

開口部を開いた状態で常に維持する構造を備え、前側と後側のフィルムを分離すると共に注ぎ口が平らになることを防ぐため、注ぎ口の内部に管が取り付けられた注ぎ口付き包装袋が、一般的に知られている。（例えば、特許文献１及び２を参照）
特開平５−１３２０６９ 特開平１０−１１９９９２ A pouch with a spout that has a structure that keeps the opening open at all times, separates the front and rear films and prevents the spout from becoming flat, with a pipe attached inside the spout Is generally known. (For example, see Patent Documents 1 and 2)
JP-A-5-132069 JP-A-10-119992

しかしながら、従来の注ぎ口付き包装袋では、内容物が粉末又は顆粒などの固体の場合、或いは高粘性液体などの流動性に乏しい製品の場合、内容物が注ぎ口を塞いでしまい、注ぐことが困難になる。   However, in a conventional packaging bag with a spout, if the content is a solid such as powder or granules, or if the product is poor in fluidity such as a highly viscous liquid, the content may block the spout and be poured. It becomes difficult.

上述のことを考慮して、本発明の１つの目的は、流動性に乏しい内容物であっても容易に注ぐことができ、内容物の残留を低減することができる、注ぎ口付き包装袋を提供することである。   In view of the above, one object of the present invention is to provide a packaging bag with a spout that can be easily poured even if the content is poor in fluidity and can reduce the residual content. Is to provide.

上述の課題を解決するため、本発明は、注ぎ口付き包装袋であって、前記包装袋の頂部に設けられた該注ぎ口の流路が、２枚のフィルムを封止することによって作られた封止区域によって仕切られ、これら２枚のフィルムを分離する形状保持部材が該注ぎ口の該流路内に設けられており、該形状保持部材が、該流路の全長に沿ってその両側を仕切る該封止区域の間に間隙を確実に形成し、該形状保持部材が該２枚のフィルムの１つのみに対して固定されており、該形状保持部材が一方のフィルムに取り付けられる該形状保持部材の取付け区域が、該形状保持部材の長手方向に延びる形状を有し、該形状保持部材が、該注ぎ口の該流路に沿った両端において管状の開口となっており、該形状保持部材の取付け区域を中心軸として該形状保持部材を揺動させることができるよう、該形状保持部材は該２枚のフィルムの１つのみに対して固定されている、注ぎ口付き包装袋を提供する。 In order to solve the above-mentioned problem, the present invention is a packaging bag with a spout, wherein the flow path of the spout provided at the top of the packaging bag is made by sealing two films. A shape-retaining member that is separated by a sealed area and separates these two films is provided in the flow path of the spout, and the shape-retaining member is disposed on both sides of the flow path along the entire length of the flow path. A gap is securely formed between the sealing areas separating the shape, the shape holding member is fixed to only one of the two films, and the shape holding member is attached to one film. The attachment area of the shape holding member has a shape extending in the longitudinal direction of the shape holding member, and the shape holding member is a tubular opening at both ends along the flow path of the pouring spout. The shape holding member with the mounting area of the holding member as the central axis To be able to swing, the shape retaining member is fixed to only one of the two films, to provide a packaging bag with pour spout.

２枚のフィルムは、好ましくは、形状保持部材の領域内で外向きに膨らむ拡張区域を有する。拡張区域は、好ましくは、内容物格納区域まで延びる。   The two films preferably have an extended area that bulges outward in the region of the shape retaining member. The extended area preferably extends to the content storage area.

注ぎ口付き包装袋はまた、注ぎ口が包装袋の角部区域に設けられ、注ぎ口の流路が包装袋から上向きの角度に向けられ、注ぎ口の流路と交差する方向に開口部を案内する開口部案内ラインが、注ぎ口の一方の側にある封止区域に設けられ、開口部案内ラインの端部区域が、包装袋の底部側と平行に延び、該開口部案内ラインの該端部区域が、その延長線が形状保持部材と交差しない位置に設けられる構造を有してもよい。   The spouted packaging bag also has a spout in the corner area of the packaging bag, the spout channel is directed upward from the packaging bag and has an opening in a direction intersecting the spout channel. An opening guide line for guiding is provided in a sealed area on one side of the spout, and an end area of the opening guide line extends parallel to the bottom side of the packaging bag, The end section may have a structure provided at a position where the extension line does not intersect the shape maintaining member.

開口部案内ラインの端部区域の延長線から形状保持部材までの距離は、好ましくは、１〜４ｍｍの範囲内である。   The distance from the extension line of the end area of the opening guide line to the shape retaining member is preferably in the range of 1 to 4 mm.

本発明の注ぎ口付き包装袋では、形状保持部材は、流路の全長に沿ってその両側を仕切る封止区域の間に間隙を確実に形成し、形状保持部材は、フィルムの形状保持部材が取り付けられる側を反対側にある他方のフィルムから分離することができ、したがって、注ぎ口の流路を広く開くことができ、効率的に注ぐことが可能である。更に、形状保持部材は、流路内の左右の側両方に揺動することができるので、内容物が注ぎ口の手前で詰まったとしても、内容物を分解して注ぎ口から容易に流出させることができる。更に、形状保持部材を他方のフィルムに対して揺り動かすことによって、フィルムの内面に付着してしまった内容物を取り除くことができるので、内容物が少ないとき、内容物のほぼ全てを残留なしに注ぎ口から注ぎ出すことができる。   In the packaging bag with spout of the present invention, the shape maintaining member reliably forms a gap between the sealed areas that divide both sides along the entire length of the flow path, and the shape maintaining member is the shape retaining member of the film. The side to be attached can be separated from the other film on the opposite side, so that the flow channel of the spout can be wide open and can be poured efficiently. Furthermore, since the shape-retaining member can swing on both the left and right sides in the flow path, even if the contents are clogged in front of the spout, the contents can be decomposed and easily flowed out of the spout. be able to. Furthermore, by shaking the shape-retaining member with respect to the other film, the contents adhering to the inner surface of the film can be removed, so when there is little content, almost all of the content is poured without residue. Can be poured out from the mouth.

形状保持部材と一方のフィルムが取り付けられる形状保持部材取付け区域が、形状保持部材の長手方向に沿って延びる形状（例えば、直線又は波線）を有するため、形状保持部材取付け区域を中心軸として形状保持部材を左右に動かすことができるので、内容物をより良好に注ぐことができ、残留内容物を最小限に抑える効果を更に高めることができる。
形状保持部材が注ぎ口の流路に沿った両端において開口となっている管であるため、流路を開いた状態で維持する機能が良好になり、内容物の流れは容易には妨げられない。更に、形状保持部材をフィルムに取り付ける作業は簡単になり、押出し成形などの効率的な成形作業が可能になるので、コストが有利になる。 Shape retaining member mounting zone one film and the shape-retaining member is attached is, for having a longitudinal direction extending along the shape of the shape-retaining member (e.g., linear or wavy line), shape retention and shape retention member attachment area about axis Since the member can be moved left and right, the contents can be poured more favorably, and the effect of minimizing the residual contents can be further enhanced.
Since the ends of the shape retaining member along a flow path of the spout a tube which is an opening, the ability to maintain in a state of open flow paths are improved, the flow of the contents can not easily be impeded . Furthermore, the work of attaching the shape-retaining member to the film is simplified, and an efficient forming operation such as extrusion is possible, which is advantageous in cost.

注ぎ口を形成した２枚のフィルムが、形状保持部材の領域内において外向きに膨らむ拡張区域を有する場合、流路の断面積はより大きくなり、内容物は注ぎ口の流路に容易に流れ込む。更に、拡張区域が内容物格納区域まで延びる場合、内容物が高粘度の液体であるときに内容物を絞り出すために包装袋の本体に圧力が加えられると、注ぎ口と内容物格納区域の間の境界領域において注ぎ口を形成するフィルムに形成される、内容物が注ぎ口に流れ込むのを妨いで注ぐことを困難にする、しわなどの問題を回避することができる。   If the two films forming the spout have an extended area that bulges outward in the area of the shape-retaining member, the cross-sectional area of the flow path becomes larger and the contents easily flow into the flow path of the spout. . In addition, if the extended area extends to the content storage area, when pressure is applied to the body of the packaging bag to squeeze the contents when the contents are a high viscosity liquid, there is a gap between the spout and the content storage area. It is possible to avoid problems such as wrinkles, which are difficult to pour by preventing the contents from flowing into the spout, which are formed in the film that forms the spout in the boundary region.

本発明の注ぎ口付き包装袋が、注ぎ口が包装袋の角部にあるようにして作成された場合、注ぎ口の流路は包装袋の上向きに角度を成した方向にあり、注ぎ口の流路と交差する方向に開口部を案内する開口部案内ラインが、注ぎ口の一方の側にある封止区域に形成され、開口部案内ラインの端部区域は包装袋の下側縁部に平行に延び、開口部案内ラインの端部区域は、延長線が形状保持部材と交差しないように位置付けられ、したがって、水平な直線状の開口部を開口部案内ラインの端部区域から形成することができる。したがって、再充填するとき、注ぎ口を空の容器に容易に挿入することができる。更に、内容物の流れは開口部区域において無秩序にならず、滑らかな流れを得ることができる。   When the packaging bag with spout of the present invention is made so that the spout is at the corner of the packaging bag, the flow path of the spout is in an angled direction upward of the packaging bag, An opening guide line that guides the opening in a direction intersecting the flow path is formed in a sealed area on one side of the spout, and the end area of the opening guide line is at the lower edge of the packaging bag Extending in parallel, the end area of the opening guide line is positioned such that the extension line does not intersect the shape-retaining member, thus forming a horizontal linear opening from the end area of the opening guide line Can do. Thus, the spout can be easily inserted into an empty container when refilling. Furthermore, the flow of the contents is not disordered in the opening area, and a smooth flow can be obtained.

本発明は、図面を参照しながら好ましい実施形態に基づいて以下に記載される。   The invention is described below on the basis of preferred embodiments with reference to the drawings.

図１（ａ）及び（ｂ）に示されるように、この実施形態の注ぎ口付き包装袋１（以下、単に「包装袋」と称される）は、同じ平面パターンを有する２枚の本体フィルム２及び３と、中心線としての折畳み線４ａで半分に折り畳まれた底部フィルム４とを備える、直立型の小袋である。底部フィルム４は、折畳み線４ａが内向きになるように折り重ねられ、一対の本体フィルム２及び３の下側部分の間に置かれる。   As shown in FIGS. 1 (a) and 1 (b), a packaging bag 1 with a spout of this embodiment (hereinafter simply referred to as “packaging bag”) has two main body films having the same plane pattern. An upright pouch comprising 2 and 3 and a bottom film 4 folded in half at a fold line 4a as a center line. The bottom film 4 is folded so that the fold line 4a faces inward, and is placed between the lower portions of the pair of main body films 2 and 3.

側縁部封止区域５ａ及び５ｂは、包装袋１の両方の側縁部上に形成される。側縁部封止区域５ａ及び５ｂの底部フィルム４よりも上にある部分では、本体フィルム２及び３の側縁部区域の両方が互いにヒートシールされ、底部フィルム４が本体フィルム２及び３の間に位置付けられる下側領域では、本体フィルム２及び３の側縁部区域は両方とも、底部フィルム４の側縁部の両方にヒートシールされる。   Side edge sealed areas 5 a and 5 b are formed on both side edges of the packaging bag 1. In the portion of the side edge sealing areas 5a and 5b above the bottom film 4, both the side edge areas of the body films 2 and 3 are heat sealed to each other so that the bottom film 4 is between the body films 2 and 3. In the lower region located at, the side edge areas of the body films 2 and 3 are both heat sealed to both the side edges of the bottom film 4.

更に、本体フィルム２及び３と底部フィルム４との互いに向かい合った表面の底縁部区域をヒートシールすることによって、底部封止区域６が包装袋１の底部区域に形成される。ちなみに、切欠（図面からは省略されている）が、底部フィルム４の一部分にあるパンチ穴などから形成され、それによって、一方の本体フィルム２が、この切欠を介して他方の本体フィルム３に直接ヒートシールされてもよい。   Furthermore, a bottom sealed area 6 is formed in the bottom area of the packaging bag 1 by heat sealing the bottom edge areas of the opposing surfaces of the body films 2 and 3 and the bottom film 4. Incidentally, a notch (omitted from the drawing) is formed from a punch hole or the like in a part of the bottom film 4, so that one main body film 2 is directly connected to the other main body film 3 through this notch. It may be heat sealed.

包装袋１の寸法は特に制限されないが、再充填容器としては、好ましい範囲は、包装袋の高さ（上部側１ａから底部側１ｂまでの寸法）がおよそ１００〜５００ｍｍ、包装袋の幅（両方の側縁部間の最大幅）がおよそ７０〜３００ｍｍ、内容物の充填容積がおよそ１００ｃｍ３〜５０００ｃｍ３である。 The dimensions of the packaging bag 1 are not particularly limited, but the preferred range for the refill container is that the height of the packaging bag (the dimension from the top side 1a to the bottom side 1b) is approximately 100 to 500 mm, and the width of the packaging bag (both the maximum width between side edges) of approximately 70～300Mm, fill volume of the contents is approximately 100cm 3 ~5000cm 3.

本体フィルム２及び３並びに底部フィルム４に使用されるフィルムは、二軸延伸（biaxially elongated）ポリプロピレン、二軸延伸（biaxially elongating）ポリアミド、又は二軸延伸ポリエステルなどから作られた基材フィルムが、低密度ポリエチレン、直鎖状低密度ポリエチレン、エチレンビニルアセテートコポリマー、又はポリプロピレンなどのポリオレフィン樹脂から作られたシーラント層によって積層された積層体構造など、従来使用されている材料であってもよい。この場合、包装袋の強度を増加させるため、基材フィルムの複数層が積層されてもよい。あるいは、気体及び紫外線に対する遮断性を増加させるため、アルミホイルなどの金属箔、セラミックなどの無機蒸着層、又はエチレンビニルアルコールコポリマーフィルムなども積層されてもよい。更に、包装袋の水平方向での易引裂き性を増加させるため、一軸延伸（uniaxially elongated）ポリオレフィン又はナイロンのフィルムなどが使用される場合、あるいは、６ナイロン又はＭＸＤ６などの芳香族ナイロンがブレンドされている樹脂フィルムを延伸することによって得られる易引裂き性ナイロンフィルムが使用される場合、任意の位置で直線状に引き裂くことができ、且つ易引裂き性を得ることができ、このことは好ましい。   The film used for the main body films 2 and 3 and the bottom film 4 is a base film made of biaxially elongated polypropylene, biaxially elongated polyamide, or biaxially stretched polyester. It may be a conventionally used material such as a laminate structure laminated with a sealant layer made from a polyolefin resin such as density polyethylene, linear low density polyethylene, ethylene vinyl acetate copolymer, or polypropylene. In this case, in order to increase the strength of the packaging bag, a plurality of layers of the base film may be laminated. Alternatively, a metal foil such as aluminum foil, an inorganic vapor deposition layer such as ceramic, an ethylene vinyl alcohol copolymer film, or the like may be laminated in order to increase the barrier against gas and ultraviolet rays. Furthermore, in order to increase the tearability of the packaging bag in the horizontal direction, a uniaxially elongated polyolefin or nylon film is used, or an aromatic nylon such as 6 nylon or MXD6 is blended. When an easily tearable nylon film obtained by stretching a resin film is used, it can be torn linearly at an arbitrary position and easily tearable, which is preferable.

更に、水平方向での易引裂き性を確保するための手段として、基材フィルムにミシン目線が形成され、次にシーラント層又は他の層が付加されてもよく、或いは、レーザービームを使用して、本体フィルムの表面に半切り溝が形成されてもよい。   Further, as a means for ensuring easy tearability in the horizontal direction, a perforation line may be formed on the base film, and then a sealant layer or other layer may be added, or a laser beam may be used. A half-cut groove may be formed on the surface of the main body film.

図１（ａ）に示されるように、注ぎ口１０は包装袋１の頂部に設けられる。この配置では、注ぎ口１０は、包装袋１の上部側１ａと一方の側縁部封止区域５ａ（図１（ａ）では左側）との間の角部１ｃに設けられる。注ぎ口１０が角部１ｃに配置された包装袋１の上部側１ａの側において、本体フィルム２及び３は、一方の側縁部封止区域５ａから延びる頂部封止区域７によって互いにヒートシールされる。包装袋１の注ぎ口１０よりも下の区域は内容物格納区域９である。更に、頂部封止区域７と他方の側縁部封止区域５ｂとの間の区域は充填ポート８として開いたままであり、充填ポート８を通して、内容物を包装袋１の内容物格納区域９に充填することができる。内容物は、粉末又は顆粒などの固体、粘稠な液体、液体、並びにそれらの混合物であってもよい。粉末又は顆粒の粒径は特に制限されないが、例えば、約１μｍ〜５ｍｍの平均粒径が提案されてもよい。粉末は、例えば、粉末洗剤、小麦粉、食卓塩、又は砂糖などであってもよい。   As shown in FIG. 1A, the spout 10 is provided at the top of the packaging bag 1. In this arrangement, the spout 10 is provided at the corner 1c between the upper side 1a of the packaging bag 1 and one side edge sealing area 5a (left side in FIG. 1A). On the side of the upper side 1a of the packaging bag 1 where the spout 10 is arranged at the corner 1c, the body films 2 and 3 are heat sealed to each other by a top sealing area 7 extending from one side edge sealing area 5a. The The area below the spout 10 of the packaging bag 1 is a content storage area 9. Furthermore, the area between the top sealing area 7 and the other side edge sealing area 5b remains open as a filling port 8, through which the contents are transferred to the contents storage area 9 of the packaging bag 1. Can be filled. The contents may be solids such as powders or granules, viscous liquids, liquids, and mixtures thereof. The particle size of the powder or granule is not particularly limited, but for example, an average particle size of about 1 μm to 5 mm may be proposed. The powder may be, for example, a powder detergent, wheat flour, table salt, or sugar.

ちなみに、内容物を充填した後、充填ポート８を密閉する（seal shut）ため、充填ポート８の縁部に沿って本体フィルム２及び３を互いにヒートシールすることによって、充填ポート封止区域８ａが包装袋１の上部側１ａに沿って形成される（図３を参照）。   Incidentally, after filling the contents, the filling port sealing area 8a is formed by heat-sealing the body films 2 and 3 together along the edge of the filling port 8 in order to seal the filling port 8. It is formed along the upper side 1a of the packaging bag 1 (see FIG. 3).

両方の封止区域５ａ及び７の間の未封止区域は、注ぎ口１０のための流路１１を形成する。換言すれば、流路１１は、一方の側縁部封止区域５ａ及び頂部封止区域７によって区切られる。一方の側部封止区域５ａは、注ぎ口１０の下側区域において、包装袋１の内側幅方向に向かって湾曲しており、頂部封止区域７は、流路１１に沿って傾斜した向きで延びる傾斜辺区域７ａを有する。流路１１の方向は、一方の側縁部封止区域５ａの湾曲区域５ｃと、頂部封止区域７の傾斜区域７ａとによって決まり、包装袋１の内部区域から角部１ｃに向かって、包装袋１の上向きに角度を成した方向（図１（ａ）の左上方）に延びる。   The unsealed area between both sealed areas 5 a and 7 forms a flow path 11 for the spout 10. In other words, the flow path 11 is delimited by one side edge sealing area 5 a and the top sealing area 7. One side sealed area 5 a is curved toward the inner width direction of the packaging bag 1 in the lower area of the spout 10, and the top sealed area 7 is inclined along the flow path 11. And has an inclined side area 7a extending in the direction. The direction of the flow path 11 is determined by the curved area 5c of the one side edge sealed area 5a and the inclined area 7a of the top sealed area 7, and the packaging from the inner area of the packaging bag 1 toward the corner 1c. The bag 1 extends in an upwardly angled direction (upper left in FIG. 1A).

注ぎ口１０の流路１１の幅は、包装袋１全体の寸法と、再充填される容器である主要容器などの寸法とに基づいて、おおよそ設計することができる。特定の一例として、注ぎ口１０が開かれる位置における幅（後述される、開口部案内ライン１４の端部区域１４ｇの延長線Ｌに沿った幅）は、好ましくは、１５〜５０ｍｍである。 The width of the flow path 11 of the spout 10 can be designed approximately based on the overall dimensions of the packaging bag 1 and the dimensions of the main container that is the container to be refilled. As a specific example, the width at the position where the spout 10 is opened (the width along the extension line L of the end section 14g of the opening guide line 14 described later) is preferably 15 to 50 mm.

注ぎ口１０の前端部１０ａは、頂部封止区域７によって閉止されるので、注ぎ口１０が開かれていない限り、内容物が注ぎ口１０から放出されることはない。   The front end 10a of the spout 10 is closed by the top sealing area 7, so that no content is discharged from the spout 10 unless the spout 10 is opened.

管は、注ぎ口１０の流路１１内における形状保持部材１２として、本体フィルム２及び３の間に取り付けられる。このようにして流路１１内に形状保持部材１２を設けることにより、２枚のフィルム２及び３を分離することができ、開いた後の注ぎ口１０の流路１１及び開口部区域１７（図３を参照）を広げた状態で維持することができる。   The tube is attached between the main body films 2 and 3 as a shape retaining member 12 in the flow path 11 of the spout 10. By providing the shape-retaining member 12 in the flow path 11 in this way, the two films 2 and 3 can be separated, and the flow path 11 and the opening area 17 (see FIG. 3) can be maintained in an expanded state.

形状保持部材１２を形成する材料は、ポリエチレン、ポリプロピレン、ポリアミド、ポリエステル、ポリスチレン、又はポリカーボネートなどの合成樹脂であってもよいが、本体フィルム２及び３の内面にあるシーラント層にヒートシールすることによって熱的に接着するため、ポリエチレン又はポリプロピレンなどのポリオレフィン樹脂類が好ましい。   The material forming the shape retaining member 12 may be a synthetic resin such as polyethylene, polypropylene, polyamide, polyester, polystyrene, or polycarbonate, but by heat sealing to the sealant layer on the inner surfaces of the main body films 2 and 3. Polyolefin resins such as polyethylene or polypropylene are preferred because they are thermally bonded.

図１（ｂ）に示されるように、本体フィルム２及び３は、形状保持部材１２の周りの領域において外に膨らむ拡張区域１３を有する。この拡張区域１３は、好ましくは、包装袋１を製造するプロセスの間に真空成形又は圧縮空気成形することによって、本体フィルム２及び３に前もって（形状保持部材１２を挿入する前に）形成される。   As shown in FIG. 1 (b), the main body films 2 and 3 have an expanded area 13 that swells outward in a region around the shape retaining member 12. This expanded area 13 is preferably formed in advance in the body films 2 and 3 (before inserting the shape retaining member 12) by vacuum forming or compressed air forming during the process of manufacturing the packaging bag 1. .

形状保持部材１２は、好ましくは、流路１１を塞ぐのを防ぐため、長手方向に固定の断面形状（円筒又はロッドなど）を有するが、内容物の流れを妨げないので、円筒がより好ましく、中でも、あらゆる表面に取り付けることが可能であり、したがってフィルムに取り付けるときの位置決めが簡単なので、円形の円筒が特に好ましい。更に、取付けプロセスの間、形状保持部材の長手方向は、好ましくは、流路１１の方向と整列される。形状保持部材１２が管（円筒体）である場合、管は、好ましくは、注ぎ口１０の流路１１に沿った向きになる（開口部が上流及び下流方向にある）ように取り付けられる。   The shape holding member 12 preferably has a cross-sectional shape fixed in the longitudinal direction (such as a cylinder or a rod) in order to prevent the flow path 11 from being blocked, but a cylinder is more preferable because it does not hinder the flow of contents. Among these, circular cylinders are particularly preferred because they can be attached to any surface and are therefore easy to position when attached to a film. Furthermore, during the attachment process, the longitudinal direction of the shape retaining member is preferably aligned with the direction of the flow path 11. When the shape holding member 12 is a tube (cylindrical body), the tube is preferably attached so as to be oriented along the flow path 11 of the spout 10 (the openings are in the upstream and downstream directions).

形状保持部材１２の寸法は、包装袋１全体の寸法及び注ぎ口１０などの寸法に基づいて、おおよそ設計することができる。特定の一例として、例えば管の場合、長さは約１０〜３０ｍｍであってもよく、外径（長手方向に直交する方向での最大幅）は約８〜２０ｍｍであってもよく、壁厚は約０．３〜２ｍｍであってもよい。   The size of the shape holding member 12 can be designed approximately based on the overall size of the packaging bag 1 and the size of the spout 10 or the like. As a specific example, for example in the case of a tube, the length may be about 10-30 mm, the outer diameter (maximum width in the direction perpendicular to the longitudinal direction) may be about 8-20 mm, and the wall thickness May be about 0.3-2 mm.

図１及び図２に示されるように、形状保持部材１２は、注ぎ口１０を形成する２つの本体フィルム２および３の一方の本体フィルム２にのみ取り付けられる。図面において、フラグ１２ａは、形状保持部材１２が本体フィルム２に取り付けられる、形状保持部材取付け区域の位置及び形状を示す。形状保持部材取付け区域１２ａは、ホットメルト又は接着剤を使用して形成されてもよいが、ヒートシールを使用することが好ましい。   As shown in FIGS. 1 and 2, the shape retaining member 12 is attached only to one of the two main body films 2 and 3 forming the spout 10. In the drawing, the flag 12 a indicates the position and shape of the shape holding member mounting area where the shape holding member 12 is mounted on the main body film 2. The shape retaining member attachment area 12a may be formed using hot melt or adhesive, but it is preferable to use heat sealing.

形状保持部材取付け区域１２ａは、形状保持部材１２の長手方向に沿って延びる形状であり、この種の形状は、例えば、形状保持部材１２の長手方向に沿って、直線状又は波線状に延びてもよい。   The shape-retaining member attachment area 12a has a shape extending along the longitudinal direction of the shape-retaining member 12, and this type of shape extends, for example, linearly or wavyly along the longitudinal direction of the shape-retaining member 12. Also good.

更に、形状保持部材１２は、封止区域５ａ及び７の間に、流路１１の両側をその全長に沿って区切る間隙１６ａ及び１６ｂを確保する。したがって、これらの間隙１６ａ及び１６ｂを流路１１として使用することができるだけではなく、形状保持部材１２は、形状保持部材取付け区域１２ａが中心にある状態で、流路１１内で前後に（一方の側縁部封止区域５ａに向いた側および頂部封止区域７に向いた側に）移動することができる。   Further, the shape retaining member 12 secures gaps 16a and 16b that divide both sides of the flow path 11 along the entire length between the sealing sections 5a and 7. Therefore, not only can these gaps 16a and 16b be used as the flow path 11, but the shape-retaining member 12 can be moved back and forth in the flow path 11 with one of the shape-retaining member mounting areas 12a in the center (one side). To the side edge sealing area 5a and the side facing the top sealing area 7).

図５に示されるように、開口部を注ぎ口１０の流路１１と交差する方向に案内する開口部案内ライン１４が、頂部封止区域７に形成される。頂部封止区域７に形成される開口部案内ライン１４の開始区域１４ａは、包装袋１の上部側１ａに設けられ、開始区域１４ａは、好ましくは、切欠又はＶ字形の切込みを有し、上部側との角度は好ましくは丸み付けられる。この種の構造では、充填された包装袋が別の物体に接触したときに、不用意に開くことを有効に防ぐことができる。   As shown in FIG. 5, an opening guide line 14 that guides the opening in a direction intersecting the flow path 11 of the spout 10 is formed in the top sealing area 7. The starting area 14a of the opening guide line 14 formed in the top sealing area 7 is provided on the upper side 1a of the packaging bag 1, the starting area 14a preferably having a notch or a V-shaped notch, The angle with the side is preferably rounded. With this type of structure, it is possible to effectively prevent the filled packaging bag from being inadvertently opened when it comes into contact with another object.

開口部案内ライン１４は、開始区域１４ａから上部側１ａに垂直に延びる垂直区域１４ｃを有し、垂直区域１４ｃの底部にある曲がり区域１４ｄで方向を変え、流路に沿って上向きの角度で延びる傾斜区域１４ｅを有し、湾曲区域１４ｆで傾斜区域１４ｅから再び方向を変え、また、包装袋１の外側に向かって包装袋１の底部側１ｂに平行に延びる端部区域１４ｇを有する。図３に示されるように、この構造の開口部案内ライン１４を形成することにより、水平方向の直線状開口部区域１７を端部区域１４ｇから形成することができる。したがって、再充填する間、注ぎ口を空の容器に容易に挿入することができる。更に、開口部区域１７における内容物の流れは無秩序にならず、滑らかな流れを得ることができる。   The opening guide line 14 has a vertical section 14c that extends perpendicularly from the start section 14a to the upper side 1a, changes direction at a bending section 14d at the bottom of the vertical section 14c, and extends at an upward angle along the flow path. It has an inclined area 14e, changes direction again from the inclined area 14e at the curved area 14f, and has an end area 14g extending parallel to the bottom side 1b of the packaging bag 1 towards the outside of the packaging bag 1. As shown in FIG. 3, by forming the opening guide line 14 of this structure, a horizontal linear opening area 17 can be formed from the end area 14g. Thus, the spout can be easily inserted into an empty container during refilling. Furthermore, the flow of the contents in the opening area 17 is not disordered and a smooth flow can be obtained.

この実施形態の包装袋１の場合、垂直区域１４ｃから傾斜区域１４ｅに沿って端部区域１４ｇまでの区域は、例えばトンプソンブレード（Thompson blade）を使用して作られた、２枚の本体フィルム２及び３を通り抜ける切れ目（貫通痕（penetrating marks））を有する。更に、垂直区域１４ｃの両方の側は、垂直区域１４ｃと開始区域１４ａの間に残っている未切断区域１４ｂによって接続されている。開始区域１４ａの切欠及び垂直区域１４ｃの貫通痕（penetrating marks）などは、好ましくは、互いに対する位置がずれるのを防ぐため、同時に形成される。   In the case of the packaging bag 1 of this embodiment, the area from the vertical area 14c to the end area 14g along the inclined area 14e is made of, for example, two main body films 2 made using a Thompson blade. And cut through 3 (penetrating marks). Furthermore, both sides of the vertical area 14c are connected by an uncut area 14b remaining between the vertical area 14c and the start area 14a. The notches in the start area 14a and the penetrating marks in the vertical area 14c are preferably formed at the same time in order to prevent their positions relative to each other.

未切断区域１４ｂの幅は、本体フィルム２及び３の材料に応じて変わるが、例えば、約０．５〜１．５ｍｍである。ちなみに、未切断区域１４ｂは、必要であれば、開口部案内ライン１４に沿って複数の位置に形成されてもよい。   Although the width | variety of the uncut area | region 14b changes according to the material of the main body films 2 and 3, it is about 0.5-1.5 mm, for example. Incidentally, the uncut area 14b may be formed at a plurality of positions along the opening guide line 14 if necessary.

開始地点１４ａから端部区域１４ｇまでの開口部案内ライン１４全体は、頂部封止区域７内に形成され、注ぎ口１０の流路１１を形成する未封止区域までは延びないので、注ぎ口１０を覆う本体フィルム２及び３の強度は弱くならず、本体フィルム２及び３の引裂けを抑制することができる。   The entire opening guide line 14 from the starting point 14a to the end area 14g is formed in the top sealed area 7 and does not extend to the unsealed area forming the flow path 11 of the spout 10, so The strength of the main body films 2 and 3 covering 10 is not weakened, and tearing of the main body films 2 and 3 can be suppressed.

更に、未切断区域１４ｂを引き裂くことにより、垂直区域１４ｃ及び傾斜区域１４ｅに囲まれた区域１５は、頂部封止区域７から引き離されてもよく、包装袋を開くときの保持タブとして使用することができる。このタブ１５を使用することにより、注ぎ口１０を端部区域１４ｇから引き裂き始めるとき、手の引裂き力が本体フィルム２および３に十分に伝達される。   Furthermore, by tearing the uncut area 14b, the area 15 surrounded by the vertical area 14c and the inclined area 14e may be separated from the top sealing area 7 and used as a holding tab when opening the packaging bag. Can do. By using this tab 15, the tearing force of the hand is sufficiently transmitted to the body films 2 and 3 when the spout 10 begins to tear from the end section 14g.

この実施形態の包装袋１を開くとき、最初に、未切断区域１４ｂが切断されて、頂部封止区域７において垂直区域１４ｃ及び傾斜区域１４ｅに囲まれたタブ１５が形成され、次に、このタブ１５が引張られ、開口部案内ライン１４の端部区域１４ｇから引裂けが始まる。それにより、引裂き線が、開口部案内ライン１４の端部区域１４ｇの延長線Ｌ（図１に示される）に沿って延びる。開口部案内ライン１４が形成されている側並びに反対側において側縁部封止区域５ａが破られると、注ぎ口１０の先端１０ａを取り除くことができ、図３に示されるように、注ぎ口１０に開口部区域１７が形成される。 When opening the packaging bag 1 of this embodiment, first the uncut area 14b is cut to form a tab 15 surrounded by a vertical area 14c and an inclined area 14e in the top sealing area 7, and then this The tab 15 is pulled and tearing begins from the end area 14g of the opening guide line 14. Thereby, the tear line extends along an extension line L (shown in FIG. 1) of the end section 14g of the opening guide line 14. When the side edge sealing area 5a is broken on the side where the opening guide line 14 is formed and on the opposite side, the tip 10a of the spout 10 can be removed and, as shown in FIG. An opening area 17 is formed in the opening.

図１に示されるように、開口部案内ライン１４の端部区域１４ｇは、好ましくは、延長線Ｌが形状保持部材１２と交差しないような位置に設けられる。それにより、開口部を端部区域１４ｇの延長線Ｌに沿って容易に作ることができるだけでなく、形状保持部材１２が開口部区域１７から露出しない。   As shown in FIG. 1, the end section 14 g of the opening guide line 14 is preferably provided at a position where the extension line L does not intersect the shape retaining member 12. Thereby, not only can the opening be easily made along the extension line L of the end section 14 g, but the shape retaining member 12 is not exposed from the opening section 17.

開口部案内ライン１４の端部区域１４ｇの延長線Ｌから形状保持部材１２までの距離ｄ（延長線Ｌに最も近い辺の端部までの距離）は、好ましくは、１〜４ｍｍの範囲内である。それにより、延長線Ｌに沿って開口部を容易に形成することができ、開口部区域１７が閉じることを有効に防ぐことができる。上述の距離ｄが短過ぎる場合、延長線Ｌに沿った開口部が困難になる可能性があるが、距離ｄが長過ぎる場合、開口部区域１７が閉じるのを防ぐことができない可能性がある。 The distance d from the extension line L of the end section 14g of the opening guide line 14 to the shape retaining member 12 (the distance from the end of the side closest to the extension line L) is preferably within a range of 1 to 4 mm. is there. Thereby, an opening part can be easily formed along the extended line L, and it can prevent effectively that the opening part area 17 closes. If the distance d is too short, the opening along the extension line L may be difficult, but if the distance d is too long, the opening area 17 may not be prevented from closing. .

注ぎ口１０が横又は下に向くように、包装袋１が傾けられている場合、内容物を開口部区域１７から注ぐことができる。図３（ａ）に示されるように、端部区域１４ｇの延長線Ｌと一方の側縁部封止区域５ａとの間に形成された角部区域は、開口部区域１７の前縁部１７ａである。一方の側縁部封止区域５ａは、注ぎ口１０の側部区域に湾曲区域５ｃを有し、したがって、湾曲区域５ｃは、空の主要容器（図面には図示なし）の開口部と接触し、これを捕らえ、包装袋１の注ぎ口１０が傾けられたときのガイドとして働く。更に、側縁部封止区域５ａは湾曲区域５ｃにおいて傾けられ、したがって、開口部区域１７の前縁部１７ａは鋭角を成し、注ぎ口１０を空の主要容器の開口部に容易に挿入することができる。   When the packaging bag 1 is tilted so that the spout 10 faces sideways or downward, the contents can be poured from the opening area 17. As shown in FIG. 3 (a), the corner area formed between the extension line L of the end area 14 g and the one side edge sealing area 5 a is the front edge 17 a of the opening area 17. It is. One side edge sealed area 5a has a curved area 5c in the side area of the spout 10, so that the curved area 5c contacts the opening of an empty main container (not shown in the drawing). This is caught and serves as a guide when the spout 10 of the packaging bag 1 is tilted. Furthermore, the side edge sealing area 5a is tilted in the curved area 5c, so that the front edge 17a of the opening area 17 forms an acute angle and the spout 10 is easily inserted into the opening of the empty main container. be able to.

内容物が注ぎ出されると、内容物の流動性が低い場合、内容物は注ぎ口１０の周りに溜まり、内容物の重量によって、フィルム２及び３の間の拡張区域が外に膨らむ。更に、内容物が例えば粉末の場合、開口部区域１７の開口部断面積が注ぎ口１０内部の流路１１の断面積よりも小さいと、注ぎ口１０の周りに溜まっている内容物は、詰まってしまうか、又は塊を形成することがある。   When the contents are poured out, if the contents are low in fluidity, the contents accumulate around the spout 10 and the expanded area between the films 2 and 3 bulges out due to the weight of the contents. Furthermore, when the content is, for example, powder, if the opening cross-sectional area of the opening area 17 is smaller than the cross-sectional area of the flow path 11 inside the spout 10, the content collected around the spout 10 is clogged. Or may form lumps.

この実施形態の包装袋１の場合、一方の本体フィルム２に取り付けられた形状形成部材１２は、他方の本体フィルム３から分離することができ、したがって、上述の状態は容易には起こらず、上述の状態が起こった場合であっても、形状保持部材１２と他方の本体フィルム３との間に間隙１６ｃが形成されるので、注ぎ口１０の流路１１は図３（ｂ）に示されるように広く開くことができ、有効に注ぐことができる。   In the case of the packaging bag 1 of this embodiment, the shape forming member 12 attached to one main body film 2 can be separated from the other main body film 3, and thus the above-described state does not easily occur, and Even when this state occurs, a gap 16c is formed between the shape holding member 12 and the other main body film 3, so that the flow path 11 of the spout 10 is as shown in FIG. Can be widely opened and poured efficiently.

更に、流路１１内の形状保持部材１２は、左右方向に前後に移動することができ、したがって、図４に示されるように、注ぎ口１０の周りの領域を包装袋１の外側から揉むことによって、且つ形状保持部材１２を他方のフィルム３に対して擦り合わせることによって、開口部区域１７の前で詰まってしまった、又は塊を形成している内容物を分解することができ、開口部区域１７から容易に注ぎ出すことができ、フィルム２及び３の内面に付着している内容物を形状保持部材１２によって取り除くことができ、最終的な注入作業の間、内容物が注ぎ口１０に残らないようにすることができる。   Furthermore, the shape-retaining member 12 in the flow path 11 can move back and forth in the left-right direction. Therefore, the area around the spout 10 is pinched from the outside of the packaging bag 1 as shown in FIG. And by rubbing the shape-retaining member 12 against the other film 3, the contents that are clogged in front of the opening area 17 or that form a lump can be disassembled. The contents can be easily poured out from the area 17 and the contents adhering to the inner surfaces of the films 2 and 3 can be removed by the shape-retaining member 12, so that the contents are poured into the spout 10 during the final pouring operation. It is possible not to remain.

形状保持部材取付け区域１２ａが、形状保持部材１２の長手方向に沿って直線状に延びる形状を有する場合、形状保持部材が前後に移動する方向は、形状保持部材取付け区域１２ａを用いて中心軸に固定することができ、したがって、形状保持部材１２を有効に前後に移動させることができ、内容物の注入を強化する効果を更に高めることができる。   When the shape-retaining member mounting area 12a has a shape extending linearly along the longitudinal direction of the shape-retaining member 12, the direction in which the shape-retaining member moves back and forth is centered on the center axis using the shape-retaining member mounting area 12a. Therefore, the shape-retaining member 12 can be effectively moved back and forth, and the effect of enhancing the content injection can be further enhanced.

好ましい一実施形態に基づいて本発明を上記に記載したが、本発明は上述の実施形態に制限されず、本発明の本質に反しない限り、様々な修正が可能である。例えば、本発明において注ぎ口が設けられる位置は包装袋の角部には制限されず、包装袋の上部側の中央区域に設けることもできる。更に、注ぎ口は、前端部が包装袋の上部側から突出する形状を有してもよい。更に、底部フィルムは必ずしも必要ではなく、包装袋は平坦な袋であってもよい。   Although the present invention has been described above based on one preferred embodiment, the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the essence of the present invention. For example, the position where the spout is provided in the present invention is not limited to the corner of the packaging bag, and can be provided in the central area on the upper side of the packaging bag. Further, the spout may have a shape in which the front end portion protrudes from the upper side of the packaging bag. Further, the bottom film is not necessarily required, and the packaging bag may be a flat bag.

（好ましい実施形態）
図１に示される形態の注ぎ口付き包装袋１は、以下の手順によって製造された。 (Preferred embodiment)
The spout-equipped packaging bag 1 in the form shown in FIG. 1 was manufactured by the following procedure.

積層体材料から作られた三層フィルム（二軸延伸（biaxially elongated）ポリエチレンテレフタレートフィルム／６ナイロンとＭＤＸ ６ナイロンを混合した樹脂フィルムを延伸することによって得られた易引裂き性ナイロンフィルム／直鎖状低密度ポリエチレン層（シーラント層））を、本体フィルム２及び３に使用し、積層体材料（二軸延伸ナイロン／直鎖状低密度ポリエチレン層（シーラント層））から作られた二層フィルムを、底部フィルム４に使用した。   Three-layer film made of laminate material (biaxially elongated polyethylene terephthalate film / 6 easy tearable nylon film obtained by stretching resin film mixed with nylon 6 and MDX 6 nylon / linear A low density polyethylene layer (sealant layer)) is used for the body films 2 and 3, and a bilayer film made from a laminate material (biaxially stretched nylon / linear low density polyethylene layer (sealant layer)), Used for bottom film 4.

最初に、圧縮空気成形又は真空成形を使用して、本体フィルム２及び３の予め定められた位置にある内容物格納区域９まで延びるように、拡張区域１３を形成した。低密度ポリエチレンから作られた円筒状の管１２を、この拡張区域１３内で注ぎ口１０の流路１１を形成する位置に挿入し、円筒状の管１２を、直線状のヒートシールによって一方の本体フィルム２に接合した。次に、本体フィルム２及び３を、シーラント層が互いに向き合うように位置付け、シーラント層が外面を形成するようにして半分に折り畳まれた底部フィルム４を、本体フィルム２及び３の間に挿入した。本体フィルム２及び３を底部フィルム４にヒートシールして、底部ヒートシール区域６を形成し、包装袋１の上側角部区域１ｃの１つにおいて流路１１を区切るように、側縁部封止区域５ａ及び５ｂ並びに頂部封止区域７を形成した。   Initially, the expanded area 13 was formed to extend to the content storage area 9 at a predetermined location of the body films 2 and 3 using compressed air or vacuum forming. A cylindrical tube 12 made of low density polyethylene is inserted into the expansion area 13 at a position where the flow channel 11 of the spout 10 is formed, and the cylindrical tube 12 is inserted into one side by a linear heat seal. Bonded to the main body film 2. Next, the body films 2 and 3 were positioned so that the sealant layers face each other, and the bottom film 4 folded in half so that the sealant layer formed the outer surface was inserted between the body films 2 and 3. The body films 2 and 3 are heat-sealed to the bottom film 4 to form a bottom heat-seal area 6 and side edge sealing so as to delimit the flow path 11 in one of the upper corner areas 1c of the packaging bag 1. Zones 5a and 5b and top seal zone 7 were formed.

次に、注ぎ口付き包装袋１を完成させるため、トンプソンブレード（Thompson blade）を用いて穴開けすることにより、頂部封止区域７に開口部案内ライン１４を形成した。 Then, to complete the pour spout-equipped packaging bag 1, by drilling with a Thompson blade (Thompson blade), to form an opening guide line 14 on the top sealing zone 7.

この実施形態では、包装袋１の高さ（上部側１ａから底部側１ｂまでの寸法）は２４０ｍｍ、包装袋１の幅（両方の側縁部間の最大寸法）は１４０ｍｍ、管１２の長さは２０ｍｍ、管１２の外径は１５ｍｍ、管１２の壁厚は０．５ｍｍ、管１２と本体フィルム２の間のヒートシールの幅は２ｍｍ、側縁部封止区域５ａ及び５ｂの間のヒートシールの幅は５ｍｍ、開口部案内ラインの端部区域１４ｇの延長線Ｌに沿った流路１１の幅は２５ｍｍ、開口部案内ライン１４の端部区域１４ｇの延長線Ｌから管１２の端部までの距離ｄは３ｍｍであった。   In this embodiment, the height of the packaging bag 1 (the dimension from the top side 1a to the bottom side 1b) is 240 mm, the width of the packaging bag 1 (the maximum dimension between both side edges) is 140 mm, and the length of the tube 12 20 mm, the outer diameter of the tube 12 is 15 mm, the wall thickness of the tube 12 is 0.5 mm, the width of the heat seal between the tube 12 and the main body film 2 is 2 mm, and the heat between the side edge sealing areas 5a and 5b The width of the flow path 11 along the extension line L of the end section 14g of the opening guide line is 25 mm, the width of the seal is 5 mm, and the end of the tube 12 from the extension line L of the end section 14g of the opening guide line 14 The distance d was 3 mm.

注ぎ口付き包装袋１に、充填ポート８から内容物としての粉末を充填した後、注ぎ口付き包装袋１を封止するため、ヒートシールすることによって充填ポート封止区域８ａを形成して、内容物で充填された包装袋（包装済み製品）を作成した。   After filling the pouched packaging bag 1 with the powder as the contents from the filling port 8, in order to seal the spouted packaging bag 1, the filling port sealing area 8a is formed by heat sealing, A packaging bag (packaged product) filled with contents was prepared.

充填された包装済み製品を使用する際、最初に開口部案内ライン１４の未切断区域１４ｂを切断し、タブ１５を頂部封止区域７から引き出し、次にこのタブ１５を保持して、開口部案内ライン１４の端部区域１４ｇから引き裂き、注ぎ口１０を開くことによって、水平な直線状の開口部区域１７を得ることができ、その前縁部１７ａが鋭角を形成する。本体フィルム２及び３は易引裂き性ナイロンフィルムを使用したので、開口作業は簡単である。   When using the filled packaged product, first the uncut area 14b of the opening guide line 14 is cut, the tab 15 is pulled out of the top sealing area 7, and then this tab 15 is held and the opening 15 By tearing from the end area 14g of the guide line 14 and opening the spout 10, a horizontal linear opening area 17 can be obtained, whose leading edge 17a forms an acute angle. Since the main body films 2 and 3 are made of easily tearable nylon films, the opening operation is simple.

湾曲区域５ｃをガイドとして使用して、注ぎ口１０の前端部１７ａを空の主要容器の注ぎ口に挿入し、粉末洗剤を再充填したとき、注ぎ口１０を滑らかに挿入することができ、注ぎ口付き包装袋１に充填されていた粉末洗剤を全て、主要容器の外にこぼすことなく、主要容器に滑らかに移すことができた。   Using the curved area 5c as a guide, the spout 10 can be smoothly inserted when the front end 17a of the spout 10 is inserted into the spout of an empty main container and refilled with powder detergent. All of the powder detergent filled in the packaging bag 1 with a mouth could be smoothly transferred to the main container without spilling out of the main container.

更に、注ぎ口付き包装袋１を、開口部案内ライン１４の端部区域１４ｇの延長線Ｌから管１２の端部までの距離ｄが約２．５ｍｍであった以外は上述と同じ条件を使用して、図１に示される形状で製造し、粉末洗剤を再充填したとき、粉末洗剤を全て、主要容器の外にこぼすことなく、主要容器に滑らかに移すことができた。   Furthermore, the packaging bag 1 with spout is used under the same conditions as described above, except that the distance d from the extension line L of the end section 14g of the opening guide line 14 to the end of the tube 12 is about 2.5 mm. Thus, when manufactured in the shape shown in FIG. 1 and refilled with powder detergent, all of the powder detergent could be smoothly transferred to the main container without spilling out of the main container.

本発明は、様々な産業分野において製品を格納し包装するのに使用することができ、例えば、好ましくは、再充填用の内容物（粉末、顆粒、及び液体など）を格納するための、注ぎ口付き包装袋として使用される。   The present invention can be used to store and package products in various industrial fields, for example, preferably pours for storing refill contents (powder, granules, liquids, etc.). Used as a packaging bag with a mouth.
