Description
本発明は、包装容器に関する。 The present invention relates to a packaging container.
シート材をヒートシールして形成された包装容器において、内部に漏斗状の注出口付き内壁袋を備え、注出口を露出、開口させることで収容物を注出可能にするものが知られている（参考文献１参照）。 A known packaging container is formed by heat sealing a sheet material and has an inner wall bag with a funnel-shaped spout inside, which can be exposed and opened to allow the contents to be poured out (see Reference 1).
特許文献１の注出口付き内壁袋は、典型的には樹脂によって形成され、その柔軟性のために十分に開口した形状が維持しにくく、好適に内容物の注出ができないおそれがあった。 The inner wall bag with a pouring outlet in Patent Document 1 is typically made of resin, and due to its flexibility it is difficult to maintain a sufficiently open shape, which may prevent the contents from being poured out properly.
本発明はこのような課題に鑑みてなされたものであり、収容物の注出がしやすい包装容器を提供することを目的とする。 The present invention was made in consideration of these problems, and aims to provide a packaging container that makes it easy to pour out the contents.
上記課題を解決するための本発明の一局面は、紙を含む第１シート材を重ねて端縁をシールして形成された収容部を含む容器本体と、紙を含む第２シート材を重ねて形成された注出補助部材とを備える包装容器であって、注出補助部材は、収容部の一端に設けられ、第１シート材が離間するとともに第２シート材が離間することで開口が形成されて内容物の注出が可能となり、注出補助部材は、幅が一定な辺を有する第１部分と、第１部分より収容部の内側寄りの第２部分と、中央部分が、第１部分から収容部の外方側に突出する形状を有する端縁と、を有し、開封後に収容部の外側の部分が露出する包装容器である。 One aspect of the present invention for solving the above problem is a packaging container comprising a container body including a storage section formed by overlapping a first sheet material including paper and sealing the edges, and a pouring auxiliary member formed by overlapping a second sheet material including paper, wherein the pouring auxiliary member is provided at one end of the storage section, and an opening is formed as the first sheet material moves away and the second sheet material moves away to allow the contents to be poured out, and the pouring auxiliary member has a first portion having sides of a constant width, a second portion closer to the inside of the storage section than the first portion, and a central portion having an edge shaped to protrude from the first portion outward from the storage section, and the packaging container has an outer portion of the storage section exposed after opening .
本発明によれば、一定の剛性、デッドホールド性を有する紙を含む第２シート材で形成された注出補助部材が開口を維持するので、収容物の注出がしやすい包装容器を提供することができる。 According to the present invention, a pouring aid member made of a second sheet material containing paper with a certain degree of rigidity and dead-hold properties maintains the opening, making it possible to provide a packaging container that allows easy pouring of the contents.
（第１実施形態）
本実施形態に係る包装容器１の平面図の例を図１の（ａ）に示し、Ａ－Ａ’線に沿った断面図の例を図１の（ｂ）、（ｃ）、（ｄ）に示す。包装容器１は容器本体１０と注出補助部材２０とを含む。容器本体１０は、第１シート材を重ねて端縁をシールして形成される。図１の（ａ）にシール箇所の一例をハッチングで示す。容器本体１０は端縁に囲まれた収容部１１を有する。容器本体１０は２枚の第１シート材を重ねて形成してもよく、１枚の第１シート材を折り返して重ねて形成してもよい。注出補助部材２０は、第２シート材を重ねて形成される。注出補助部材２０は、収容部１１の内部から外部にかけて第１シート材に挟まれて設けられる。図１の（ｂ）に示すように、注出補助部材２０は、２枚の第２シート材を重ねて形成してもよく、図１の（ｃ）、（ｄ）に示すように、１枚の第２シート材を折り返して重ねて形成してもよい。
First Embodiment
FIG. 1A shows an example of a plan view of the packaging container 1 according to this embodiment, and FIG. 1B, FIG. 1C, and FIG. 1D show examples of cross-sectional views along line A-A'. The packaging container 1 includes a container body 10 and a pouring assisting member 20. The container body 10 is formed by overlapping a first sheet material and sealing the edges. FIG. 1A shows an example of a sealed portion by hatching. The container body 10 has a storage section 11 surrounded by the edges. The container body 10 may be formed by overlapping two first sheet materials, or may be formed by folding back and overlapping one first sheet material. The pouring assisting member 20 is formed by overlapping a second sheet material. The pouring assisting member 20 is provided between the first sheet material from the inside to the outside of the storage section 11. As shown in FIG. 1B, the pouring assisting member 20 may be formed by overlapping two second sheet materials, or as shown in FIG. 1C and FIG. 1D, the pouring assisting member 20 may be formed by folding back and overlapping one second sheet material.
注出補助部材２０は、一例として、収容部１１より外側に配置される、幅（紙面左右方向の長さ）が一定である第１部分２１と、収容部１１の内側に配置される、第１部分２１から離れるにつれて幅が小さくなる第２部分２２とを含む。図示する例では、第２部分２２の形状は、半円形状であるが、限定されず、他の形状でもよい。また、注出補助部材２０の幅方向の側縁は、第１部分２１においては、第２シート材が互いに接続していてもよいし（図１の（ｃ）、（ｄ））、接続していなくてもよい（図１の（ｂ））が、他の部分においては、第２シート材は接続されていないことが好ましい。 As an example, the pouring assistance member 20 includes a first portion 21 that is disposed outside the storage portion 11 and has a constant width (length in the left-right direction of the page), and a second portion 22 that is disposed inside the storage portion 11 and has a width that decreases with distance from the first portion 21. In the example shown, the shape of the second portion 22 is semicircular, but this is not limited and may be other shapes. In addition, the side edges in the width direction of the pouring assistance member 20 may be connected to each other in the first portion 21 ((c) and (d) in FIG. 1) or may not be connected ((b) in FIG. 1), but it is preferable that the second sheet materials are not connected in other portions.
図２の（ａ）に注出補助部材２０の平面図を示す。注出補助部材２０は、第１部分２１から、突出する端縁２３を有する。端縁２３は、両端部より中央部分が、収容部１１の外側となる方向に向かって突出する。図２の（ａ）に示す例では、端縁２３は楕円弧形状であるが、端縁２３の形状はこれに限定されない。図２の（ｂ）、（ｃ）に、他の例に係る注出補助部材２０の平面図を示す。図２の（ｂ）に示す例では、端縁２３は両端部が丸面取りされ、中央部が直線の形状を有する。図２の（ｃ）に示す例では、端縁２３は両端部が４５°で角面取りされ、中央部が直線の形状を有する。 2(a) shows a plan view of the spouting support member 20. The spouting support member 20 has an edge 23 protruding from the first portion 21. The edge 23 protrudes from both ends toward the outside of the storage portion 11 at the center. In the example shown in FIG. 2(a), the edge 23 has an elliptical arc shape, but the shape of the edge 23 is not limited to this. FIGS. 2(b) and 2(c) show plan views of other examples of the spouting support member 20. In the example shown in FIG. 2(b), the edge 23 has both ends chamfered at a rounded angle and a straight line at the center. In the example shown in FIG. 2(c), the edge 23 has both ends chamfered at a 45° angle and a straight line at the center.
容器本体１０は、第１シート材が注出補助部材２０を挟む部分から離れるにつれて、収容部１１の幅が徐々に大きくなる漏斗部分１２を有するよう第１シート材がシールされている。 The first sheet material of the container body 10 is sealed so as to have a funnel portion 12 in which the width of the storage section 11 gradually increases as the first sheet material moves away from the portion that holds the dispensing assisting member 20.
また、容器本体１０は、注出補助部材２０を密封するよう、注出補助部材２０の収容部１１より外側の部分を取り囲むように第１シート材がシールされている。なお、収容部１１の外側の第１シート材のシール箇所は、注出補助部材２０の近くまで設けられることが好ましい。これにより、後述する包装容器１の開封まで、注出補助部材２０の第２シート材の遊びを抑制して離間しにくくして、収容物が開封前に注出補助部材２０を通過することを抑制する。これにより開封時に収容物がこぼれて散乱することを抑制できる。 The container body 10 is sealed with a first sheet material that surrounds the portion of the pouring assisting member 20 outside the storage section 11 so as to seal the pouring assisting member 20. It is preferable that the sealed portion of the first sheet material outside the storage section 11 is provided close to the pouring assisting member 20. This prevents the second sheet material of the pouring assisting member 20 from moving and separating until the packaging container 1 is opened, as described below, and prevents the contents from passing through the pouring assisting member 20 before opening. This prevents the contents from spilling and scattering when opened.
また、容器本体１０は、注出補助部材２０の収容部１１より外側の部分を横断する位置において、第１シート材に強度弱化線１３が形成されている。強度弱化線１３はミシン目やハーフカット等、限定されない。なお、強度弱化線１３より、収容部１１側において、第１シート材と第２シート材とがシールされており、収容部１１の反対側においては、第１シート材と第２シート材とがシールされていない。なお、強度弱化線１３より、収容部１１側において、第２シート材は、第１シート材との間に、収容物が漏れる隙間ができないように全幅にわたってシールされた部分を有すればよく、全体が第１シート材とシールされていなくてもよい。例えば、第２シート材の第２部分２２は、第１シート材とシールされていなくてもよい。また、容器本体１０には、強度弱化線１３の端部においてノッチ１４を設けてもよい。 In addition, the container body 10 has a weakened line 13 formed in the first sheet material at a position that crosses the portion of the auxiliary pouring member 20 outside the storage section 11. The weakened line 13 is not limited to a perforation or half cut. The first sheet material and the second sheet material are sealed on the storage section 11 side from the weakened line 13, and the first sheet material and the second sheet material are not sealed on the opposite side of the storage section 11. The second sheet material may not be entirely sealed to the first sheet material as long as it has a portion sealed over its entire width on the storage section 11 side from the weakened line 13 so that no gap is formed between the second sheet material and the first sheet material through which the contents leak. For example, the second portion 22 of the second sheet material may not be sealed to the first sheet material. The container body 10 may also have a notch 14 at the end of the weakened line 13.
第１シート材と、第２シート材とは、いずれも、紙を含む素材を好適に用いることができる。第１シート材は、例えば、包装容器１の外側から、バリア性を付与した紙（坪量７０ｇ／ｍ２）／ヒートシールニスの層構成を採用できる。あるいは、透明蒸着ＰＥＴ（ポリエチレンテレフタレート）１２μｍ／ＮＹ（ナイロン）１５μｍ／ＰＥ（ポリエチレン）５０μｍの層構成を採用できる。あるいは、ＰＥＴ１２μｍ／ＡＬ（アルミニウム箔）９μｍ／ＮＹ１５μｍ／ＰＥ５０μｍの層構成を採用できる。あるいは、ＰＥＴ１２μｍ／ＮＹ１５μｍ／ＡＬ７μｍ／ＰＥ６０μｍの層構成を採用できる。あるいは、透明蒸着ＰＥＴ１２μｍ／ＰＥ６０μｍの層構成を採用できる。あるいは、ＰＥＴ１２μｍ／ＡＬ９μｍ／ＰＥ７０μｍの層構成を採用できる。また、第２シート材は、包装容器１の外側からＰＥ３０μｍ／紙（坪量２８６．１ｇ／ｍ２）／ＰＥ３０μｍの層構成を採用できる。あるいは、ＰＥ３０μｍ／紙（坪量１９０ｇ／ｍ２）の層構成を採用できる。 Both the first sheet material and the second sheet material can be suitably made of a material containing paper. For example, the first sheet material can be made of a layer structure of paper (basis weight 70 g/m 2 ) with barrier properties/heat seal varnish from the outside of the packaging container 1. Alternatively, a layer structure of transparent vapor-deposited PET (polyethylene terephthalate) 12 μm/NY (nylon) 15 μm/PE (polyethylene) 50 μm can be used. Alternatively, a layer structure of PET 12 μm/AL (aluminum foil) 9 μm/NY 15 μm/PE 50 μm can be used. Alternatively, a layer structure of PET 12 μm/NY 15 μm/AL 7 μm/PE 60 μm can be used. Alternatively, a layer structure of transparent vapor-deposited PET 12 μm/PE 60 μm can be used. Alternatively, a layer structure of PET 12 μm/AL 9 μm/PE 70 μm can be used. The second sheet material may have a layer structure of PE 30 μm/paper (basis weight 286.1 g/m 2 )/PE 30 μm from the outside of the packaging container 1. Alternatively, a layer structure of PE 30 μm/paper (basis weight 190 g/m 2 ) may be used.
収容部１１の収容物は限定されないが、例えば、収容部１１は粉体を好適に収容することができる。なお、収容物の収容は、例えば、容器本体１０の一端縁をシールしていない状態で行い、その後端縁をシールする。 The contents of the storage section 11 are not limited, but for example, the storage section 11 can suitably store powder. Note that the contents are stored in a state where one edge of the container body 10 is not sealed, and then the edge is sealed.
以下に、収容物の注出の方法を説明する。まず、図３に示すように、容器本体１０を強度弱化線１３に沿って破断して、収容部１１の反対側の部分を除去する。これにより、包装容器１が開封され、注出補助部材２０の収容部１１の外側の部分が露出する。 The method of pouring out the contents will be described below. First, as shown in FIG. 3, the container body 10 is broken along the weakened line 13, and the portion opposite the storage section 11 is removed. This opens the packaging container 1, and the portion of the pouring assistance member 20 outside the storage section 11 is exposed.
つぎに、注出補助部材２０の収容部１１の外側の部分を、注出先の詰め替え容器等の開口部の内部に挿入する。これは例えば、包装容器１のうち、注出補助部材２０が設けられた部分を下向きに折り返して、行うことができる。 Next, the outer portion of the storage section 11 of the pouring assistance member 20 is inserted into the opening of the refill container or the like to which the liquid is to be poured. This can be done, for example, by folding the portion of the packaging container 1 on which the pouring assistance member 20 is provided downward.
注出補助部材２０は、端縁２３が突出する形状を有するので、先端部分をまず詰め替え容器等の開口部に容易に挿入することができる。その後、挿入を進めると、端縁２３の端部と第１部分２１とが比較的滑らかに接続しているので、第１部分２１のコーナー部分が詰め替え容器等の開口部に引っかかることなく、第１部分２１を全幅にわたってスムーズに挿入することができる。 Since the dispensing assisting member 20 has a shape with a protruding edge 23, the tip portion can be easily inserted first into the opening of a refillable container or the like. Then, as the insertion proceeds, the end of the edge 23 and the first portion 21 connect relatively smoothly, so that the corners of the first portion 21 do not get caught in the opening of a refillable container or the like, and the first portion 21 can be smoothly inserted across its entire width.
その後、包装容器１全体を下向きにして、収容物の注出を行う。この状態における、注出補助部材２０の第１部分２１を含む断面図を図４に示す。図４に示すように、注出補助部材２０は、詰め替え容器の開口部３０に挿入され、収容物の重みによって、第２シート材が幅方向の中央部分において互いに離間し、開口が形成されている。第１シート材および第２シート材は、紙を含むので、一定の剛性、デッドホールド性を有し、開口が維持されやすい。とくに第２シート材が、開口をより維持しやすくする。これにより、収容物は開口を好適に通過することができる。なお、開口は、ユーザーが第１部分２１の側縁をつまむことによって、形成することもできる。注出補助部材２０の第１部分２１は、幅が一定であるので、注出補助部材２０を詰め替え容器の開口部３０に挿入した状態を維持しやすく、また、先細り形状である場合に比べて注出される収容物が詰まりにくい。 Then, the entire packaging container 1 is turned downward to pour out the contents. A cross-sectional view including the first part 21 of the pouring assisting member 20 in this state is shown in FIG. 4. As shown in FIG. 4, the pouring assisting member 20 is inserted into the opening 30 of the refillable container, and the weight of the contents causes the second sheet material to separate from each other at the center part in the width direction, forming an opening. Since the first sheet material and the second sheet material contain paper, they have a certain rigidity and dead hold property, and the opening is easily maintained. In particular, the second sheet material makes it easier to maintain the opening. This allows the contents to pass through the opening suitably. The opening can also be formed by the user pinching the side edge of the first part 21. Since the first part 21 of the pouring assisting member 20 has a constant width, it is easy to maintain the state where the pouring assisting member 20 is inserted into the opening 30 of the refillable container, and the contents being poured out are less likely to clog compared to when it has a tapered shape.
また、収容物の注出の際、収容物の移動によって、漏斗部分１２近傍において収容部１１が膨らんで第１シート材が互いに離間すると収容部１１が漏斗形状となるので、好適に収容物を注出することができる。また、注出補助部材２０の収容部１１の内側の部分において、第２シート材も、第１シート材の漏斗形状に沿うように互いに離間するが、この部分に設けられた第２部分２２は、第１部分２１から離れるにつれて幅が小さくなるので、第１シート材の漏斗形状に沿いやすく、また、収容物の移動にともなう第１シート材の変形に影響を与えにくく、内容物の注出を妨げない。 In addition, when the contents are poured out, the movement of the contents causes the storage section 11 to expand near the funnel portion 12, and the first sheet materials separate from each other, forming a funnel shape in the storage section 11, allowing the contents to be poured out conveniently. In addition, in the part inside the storage section 11 of the pouring assistance member 20, the second sheet materials also separate from each other to follow the funnel shape of the first sheet material, but the second portion 22 provided in this part becomes narrower as it moves away from the first portion 21, so it easily follows the funnel shape of the first sheet material, is less likely to affect the deformation of the first sheet material due to the movement of the contents, and does not interfere with the pouring out of the contents.
以上のように、本実施形態に係る包装容器１では、一定の剛性、デッドホールド性を有する紙を含む第２シート材で形成された注出補助部材２０を備えることにより、好適に開口を形成、維持できるので、好適に内容物を注出することができる。また、容器本体１０に紙を含む第１シート材を用い、注出補助部材２０に紙を含む第２シート材を用いるので、樹脂材料等の使用量を低減し、環境負荷を低減することができる。また、とくに端縁２３により、詰め替え容器等の開口部に注出補助部材２０を挿入しやすくすることができる。 As described above, the packaging container 1 according to this embodiment is provided with a pouring assisting member 20 made of a second sheet material containing paper that has a certain degree of rigidity and dead-hold properties, which allows the opening to be formed and maintained appropriately, and the contents to be poured out appropriately. In addition, since the container body 10 uses a first sheet material containing paper and the pouring assisting member 20 uses a second sheet material containing paper, the amount of resin material used can be reduced, and the environmental load can be reduced. In addition, the edge 23 in particular makes it easier to insert the pouring assisting member 20 into the opening of a refillable container or the like.
（第２実施形態）
第１実施形態に係る包装容器１においては、注出補助部材２０を容器本体１０の内部に設けるのに対して、本実施形態に係る包装容器２においては、注出補助部材２０を容器本体１０の外部に設ける。以下、第１実施形態との相違点を中心に説明し、同様の事項については説明を省略あるいは簡略化する。また、第１実施形態と同一、あるいは、対応する構成要素については同一の参照符号を付す。
Second Embodiment
In the packaging container 1 according to the first embodiment, the pouring assist member 20 is provided inside the container body 10, whereas in the packaging container 2 according to the present embodiment, the pouring assist member 20 is provided outside the container body 10. Hereinafter, differences from the first embodiment will be mainly described, and descriptions of similar matters will be omitted or simplified. Also, the same reference numerals will be used for components that are the same as or correspond to those of the first embodiment.
本実施形態に係る包装容器２の平面図の例を図５の（ａ）に示し、Ｂ－Ｂ’線に沿った断面図の例を図５の（ｃ）、（ｄ）、（ｅ）、（ｆ）に示す。包装容器１は容器本体１０と注出補助部材２０とを含む。図５の（ｂ）に、包装容器１から注出補助部材２０を外した平面図を示す。容器本体１０は、第１シート材を重ねて端縁をシールして形成される。図５の（ａ）、（ｂ）にシール箇所の一例をハッチングで示す。容器本体１０は端縁に囲まれた収容部１１を有する。容器本体１０は２枚の第１シート材を重ねて形成してもよく、１枚の第１シート材を折り返して重ねて形成してもよい。注出補助部材２０は、第２シート材を重ねて形成される。注出補助部材２０は、収容部１１の一端において、第１シート材を挟んで設けられる。図５の（ｃ）に示すように、注出補助部材２０は、２枚の第２シート材を、容器本体１０の幅（紙面左右方向の長さ）に合わせて重ねて形成してもよく、図５の（ｄ）に示すように、２枚の第２シート材を、容器本体１０の幅より狭い範囲に重ねて形成してもよい。また注出補助部材２０は、図５の（ｅ）、（ｆ）に示すように、１枚の第２シート材を折り返して重ねて形成してもよい。第１シート材および第２シート材の接着は、溶着によって行ってもよいし、接着剤等によって行ってもよい。また、接着の位置や範囲は限定されない。 5A shows an example of a plan view of the packaging container 2 according to this embodiment, and FIGS. 5C, 5D, 5E, and 5F show examples of cross-sectional views along the line B-B'. The packaging container 1 includes a container body 10 and a pouring assisting member 20. FIG. 5B shows a plan view of the packaging container 1 with the pouring assisting member 20 removed. The container body 10 is formed by overlapping a first sheet material and sealing the edges. FIGS. 5A and 5B show an example of a sealed portion by hatching. The container body 10 has a storage section 11 surrounded by the edges. The container body 10 may be formed by overlapping two first sheet materials, or may be formed by folding back and overlapping one first sheet material. The pouring assisting member 20 is formed by overlapping a second sheet material. The pouring assisting member 20 is provided at one end of the storage section 11, sandwiching the first sheet material. As shown in FIG. 5(c), the pouring assist member 20 may be formed by overlapping two sheets of the second sheet material to match the width of the container body 10 (the length in the left-right direction of the paper), or as shown in FIG. 5(d), two sheets of the second sheet material may be overlapped in an area narrower than the width of the container body 10. Also, as shown in FIG. 5(e) and (f), the pouring assist member 20 may be formed by folding back and overlapping one sheet of the second sheet material. The first sheet material and the second sheet material may be bonded by welding or with an adhesive or the like. The position and range of bonding are not limited.
注出補助部材２０は、一例として、幅が一定である第１部分２１と、第１部分２１より収容部１１の内側寄りの、第１部分２１から離れるにつれて幅が小さくなる第２部分２２とを含む。図示する例では、第２部分２２の形状は、半円形状であるが、限定されず、他の形状でもよい。また、注出補助部材２０の幅方向の側縁は、第１部分２１においては、第２シート材が互いに接続していてもよいし（図５の（ｅ）、（ｆ））、接続していなくてもよい（図５の（ｃ）、（ｄ））が、他の部分においては、第２シート材は接続されていないことが好ましい。 As an example, the pouring assistance member 20 includes a first portion 21 having a constant width, and a second portion 22 that is closer to the inside of the storage section 11 than the first portion 21 and that decreases in width as it moves away from the first portion 21. In the example shown, the shape of the second portion 22 is semicircular, but this is not limited and other shapes are also possible. In addition, the side edges in the width direction of the pouring assistance member 20 may be connected to each other in the first portion 21 ((e) and (f) of FIG. 5) or may not be connected ((c) and (d) of FIG. 5), but it is preferable that the second sheet materials are not connected in other portions.
注出補助部材２０は、平坦に重ね合わされているので、後述する包装容器１の開封まで、容器本体１０の第１シート材の遊びを抑制して離開しにくくして、収容物が開封前に注出補助部材２０に挟まれた部分を通過することを抑制する。これにより開封時に収容物がこぼれて散乱することを抑制できる。 Since the pouring assistance member 20 is stacked flat, it prevents the first sheet material of the container body 10 from moving and separating until the packaging container 1 is opened (described later), and prevents the contents from passing through the portion sandwiched between the pouring assistance member 20 before opening. This prevents the contents from spilling and scattering when the container is opened.
また、容器本体１０においては、注出補助部材２０の収容部１１外方側端縁の近傍が開口予定部である。開口予定部において、容器本体１０に強度弱化線１３が形成されている。強度弱化線１３はミシン目やハーフカット等、限定されない。また、容器本体１０には、強度弱化線１３の端部においてノッチ１４を設けてもよい。 In addition, in the container body 10, the vicinity of the outer edge of the storage section 11 of the dispensing assistant member 20 is the intended opening portion. In the intended opening portion, a weakened line 13 is formed in the container body 10. The weakened line 13 is not limited to a perforation or a half cut. In addition, the container body 10 may be provided with a notch 14 at the end of the weakened line 13.
以下に、収容物の注出の方法を説明する。まず、図６に示すように、容器本体１０を強度弱化線１３に沿って破断して、収容部１１の端部を除去する。これにより、包装容器１が開封される。 The method of pouring out the contents will be described below. First, as shown in FIG. 6, the container body 10 is broken along the weakened line 13, and the end of the storage section 11 is removed. This opens the packaging container 1.
つぎに、注出補助部材２０を、注出先の詰め替え容器等の開口部の内部に挿入する。これは例えば、包装容器１のうち、注出補助部材２０が設けられた部分を下向きに折り返して、行うことができる。 Next, the pouring assistance member 20 is inserted into the opening of the refill container or the like to which the liquid is to be poured. This can be done, for example, by folding downward the portion of the packaging container 1 where the pouring assistance member 20 is provided.
その後、包装容器１全体を下向きにして、収容物の注出を行う。この状態における、注出補助部材２０の第１部分２１、容器本体１０を含む断面図を図７に示す。図７に示すように、注出補助部材２０は、詰め替え容器の開口部３０に挿入され、収容物の重みによって、第１シート材が幅方向の中央部分において互いに離間し、開口が形成されている。 Then, the entire packaging container 1 is turned downward to pour out the contents. Figure 7 shows a cross-sectional view of the first part 21 of the pouring assist member 20 and the container body 10 in this state. As shown in Figure 7, the pouring assist member 20 is inserted into the opening 30 of the refill container, and the weight of the contents causes the first sheet materials to separate from each other in the widthwise center portion, forming an opening.
本実施形態の変形例を説明する。第１変形例に係る容器本体１０の平面図を図８の（ａ）に示す。この例では、漏斗部分１２より上方の部分を、漏斗部分１２の最小幅より幅広にし、図８の（ｂ）に示すように側縁を折り返した状態で、図示しない注出補助部材を取り付ける。また、第２変形例に係る容器本体１０の平面図を図９の（ａ）に示す。この例では、漏斗部分１２より上方の部分を、漏斗部分１２の最小幅と同じ幅とし、図９の（ｂ）に示すように側縁を折り返した状態で、図示しない注出補助部材を取り付ける。これらの変形例によれば、注出補助部材の大きさが同じでも、容器本体１０の、注出補助部材に挟まれる部分を、より幅広に設けることが容易となる。図１０に、これらの変形例において、収容物の注出を行っている状態における、注出補助部材の第１部分２１、容器本体１０を含む断面図を示す。図１０に示すように、注出時には、折り返された容器本体１０の折り返し位置が側縁寄りに移動して、図７に示す例よりも、第１シート材が幅方向の中央部分において互いにより大きく離間し、より好適に開口が形成される。 A modified example of this embodiment will be described. A plan view of the container body 10 according to the first modified example is shown in FIG. 8 (a). In this example, the part above the funnel portion 12 is made wider than the minimum width of the funnel portion 12, and a pouring auxiliary member (not shown) is attached with the side edge folded back as shown in FIG. 8 (b). Also, a plan view of the container body 10 according to the second modified example is shown in FIG. 9 (a). In this example, the part above the funnel portion 12 is made the same width as the minimum width of the funnel portion 12, and a pouring auxiliary member (not shown) is attached with the side edge folded back as shown in FIG. 9 (b). According to these modified examples, even if the size of the pouring auxiliary member is the same, it is easy to make the part of the container body 10 sandwiched between the pouring auxiliary member wider. FIG. 10 shows a cross-sectional view including the first part 21 of the pouring auxiliary member and the container body 10 in the state where the contents are being poured out in these modified examples. As shown in FIG. 10, when pouring, the folding position of the folded container body 10 moves toward the side edge, and the first sheet material is spaced farther apart from each other in the center part in the width direction than in the example shown in FIG. 7, and an opening is formed more appropriately.
本実施形態に係る包装容器２においても、第１実施形態と同様、一定の剛性、デッドホールド性を有する紙を含む第２シート材で形成された注出補助部材２０を備えることにより、好適に開口を形成、維持できるので、好適に内容物を注出することができる。また、容器本体１０に紙を含む第１シート材を用い、注出補助部材２０に紙を含む第２シート材を用いるので、樹脂材料等の使用量を低減し、環境負荷を低減することができる。また、とくに端縁２３により、詰め替え容器等の開口部に注出補助部材２０を挿入しやすくすることができる。 In the packaging container 2 according to this embodiment, as in the first embodiment, the pouring assisting member 20 is made of a second sheet material containing paper that has a certain degree of rigidity and dead-hold properties, so that the opening can be formed and maintained appropriately, and the contents can be poured out appropriately. In addition, since the container body 10 uses a first sheet material containing paper, and the pouring assisting member 20 uses a second sheet material containing paper, the amount of resin material used can be reduced, and the environmental load can be reduced. In addition, the edge 23 in particular makes it easier to insert the pouring assisting member 20 into the opening of a refillable container or the like.
