本発明は、天部側シートと底部側シートとを重ね、その周縁で全周に渡って互いに固定して構成された容器であって、平坦な状態で供給され、これを立ち上げて箱型の状態に変形することのできる包装容器に関するものである。 The present invention relates to a container constructed by stacking a top-side sheet and a bottom-side sheet and fixing them to each other along the entire circumference at the rims of the sheets. It relates to a packaging container that can be transformed into the state of

このような包装容器は、例えば、特許文献１に記載されている。 Such packaging containers are described, for example, in US Pat.

この包装容器１’は次のようなものである。 This packaging container 1' is as follows.

すなわち、この包装容器１’に使用する天部側シート１Ａ’は、図１１に示すように、その中央に長方形状の天面１Ａ’１０を有しており、この天面１Ａ’１０には開口部１Ａ’１１が設けられている。 That is, the top side sheet 1A' used for this packaging container 1' has a rectangular top surface 1A'10 in the center thereof, as shown in FIG. An opening 1A'11 is provided.

次に、天部側シート１Ａ’は、長方形状の天面１Ａ’１０の各辺を折り曲げ用罫線として、この天面１Ａ’１０の各辺を一辺とする四角形状の天部側側面１Ａ’２１～１Ａ’２４を有している。天部側側面１Ａ’２１～１Ａ’２４の数は、多角形状天面１Ａ’１０の辺の数と同じ４である。 Next, the top side sheet 1A' is formed into a rectangular top side surface 1A' having each side of the rectangular top surface 1A'10 as a ruled line for folding. 21 to 1A'24. The number of side surfaces 1A'21 to 1A'24 on the side of the top portion is four, which is the same as the number of sides of the polygonal top surface 1A'10.

また、天部側シート１Ａ’は、互いに隣接する各天部側側面の間に、この天部側側面１Ａ’２１～１Ａ’２４同士を繋ぐ天部側つなぎ片１Ａ’３１～１Ａ’３４を有している。すなわち、天部側側面１Ａ’２１と天部側側面１Ａ’２２との間は天部側つなぎ片１Ａ’３１で繋がれている。また、天部側側面１Ａ’２２と天部側側面１Ａ’２３との間は天部側つなぎ片１Ａ’３２で繋がれている。その他の天部側側面についても同様である。なお、各天部側側面１Ａ’２１～１Ａ’２４と天部側つなぎ片１Ａ’３１～１Ａ’３４との間には折り曲げ用罫線が設けられている。 Further, the top-side sheet 1A' has top-side connecting pieces 1A'31 to 1A'34 that connect the top-side side surfaces 1A'21 to 1A'24 between the top-side side surfaces that are adjacent to each other. have. That is, the top-side connecting piece 1A'31 connects the top-side side surface 1A'21 and the top-side side surface 1A'22. The top-side side surface 1A'22 and the top-side side surface 1A'23 are connected by a top-side connecting piece 1A'32. The same applies to the other side surfaces on the top side. Folding lines are provided between the top side side surfaces 1A'21 to 1A'24 and the top side connecting pieces 1A'31 to 1A'34.

そして、この天部側つなぎ片１Ａ’３１～１Ａ’３４によって、天部側側面１Ａ’２１～１Ａ’２４の間は閉塞されている。図示のように、この例では、天部側側面１Ａ’２１～１Ａ’２４と天部側つなぎ片１Ａ’３１～１Ａ’３４とを併せた部分の外形は長方形を構成しており、各天部側つなぎ片１Ａ’３１～１Ａ’３４はその角部に位置して、天部側側面１Ａ’２１～１Ａ’２４の間を閉塞している。例えば、天部側側面１Ａ’２１と天部側側面１Ａ’２２との間は天部側つなぎ片１Ａ’３１で閉塞している。 The top side connecting pieces 1A'31 to 1A'34 close the top side side surfaces 1A'21 to 1A'24. As shown in the figure, in this example, the outer shape of the combined portion of the top-side side surfaces 1A'21 to 1A'24 and the top-side connecting pieces 1A'31 to 1A'34 constitutes a rectangle. The section-side connecting pieces 1A'31 to 1A'34 are positioned at the corners to block the space between the top-side side surfaces 1A'21 to 1A'24. For example, the top side connecting piece 1A'31 closes the space between the top side surface 1A'21 and the top side side surface 1A'22.

この天部側つなぎ片１Ａ’３１～１Ａ’３４は、天面１Ａ’１０の各頂点から、天部側つなぎ片１Ａ’３１～１Ａ’３４を二等分する天部側二つ折り用罫線を有している。すなわち、図１１に拡大して示すように、例えば、天部側側面１Ａ’２３と天部側側面１Ａ’２４とは、天面１Ａ’１０の頂点１Ａ’１０ｂを共有している。天部側側面１Ａ’２３を構成する辺のうち、天面１Ａ’１０の頂点１Ａ’１０ｂを共有している辺には、符号１Ａ’２３ｂを付して示している。また、天部側側面１Ａ’２４を構成する辺のうち、天面１Ａ’１０の頂点１Ａ’１０ｂを共有している辺には、符号１Ａ’２４ｂを付して示している。そして、この辺１Ａ’２３ｂと辺１Ａ’２４ｂとがなす角を二等分する天部側二つ折り用罫線１Ａ’３３ｃが設けられ、この天部側二つ折り用罫線１Ａ’３３ｃによって、天部側つなぎ片１Ａ’３３は２つの領域１Ａ’３３１，１Ａ’３３２に区分されている。すなわち、図において、辺１Ａ’２３ｂと二つ折り用罫線１Ａ’３３ｃとがなす角θ１と、辺１Ａ２４ｂと天部側二つ折り用罫線１Ａ３３ｃとがなす角θ２とは等しく、領域１Ａ’３３１と領域１Ａ’３３２とは、同形同大で、しかも、天部側二つ折り用罫線１Ａ’３３
ｃを対称軸として線対称に配置されている。以上天部側つなぎ片１Ａ’３３を例として天部側二つ折り用罫線１Ａ’３３ｃについて説明したが、その他の天部側つなぎ片１Ａ’３１～１Ａ’３２，１Ａ’３４にも同様に天部側二つ折り用罫線１Ａ’３１ｃ～１Ａ’３２ｃ，１Ａ’３４ｃが設けられている。 These top-side connecting pieces 1A'31 to 1A'34 have top-side double-folding creases that bisect the top-side connecting pieces 1A'31 to 1A'34 from each vertex of the top surface 1A'10. have. That is, as shown enlarged in FIG. 11, for example, the top side surface 1A'23 and the top side surface 1A'24 share the vertex 1A'10b of the top surface 1A'10. Of the sides forming the top-side side surface 1A'23, the sides sharing the vertex 1A'10b of the top surface 1A'10 are denoted by reference numeral 1A'23b. Further, among the sides forming the top side surface 1A'24, the side sharing the vertex 1A'10b of the top surface 1A'10 is denoted by reference numeral 1A'24b. A top-side double-folding ruled line 1A'33c is provided to bisect the angle formed by the side 1A'23b and the side 1A'24b. The connecting piece 1A'33 is divided into two regions 1A'331 and 1A'332. That is, in the figure, the angle θ1 formed by the side 1A′23b and the double-folding ruled line 1A′33c is equal to the angle θ2 formed by the side 1A24b and the top-side double-folding ruled line 1A33c, and the area 1A′331 and the area 1A'332 is the same shape and size, and the crease line 1A'33 for top side double folding
They are arranged line-symmetrically with c as the axis of symmetry. The top-side double-folding ruled line 1A'33c has been described above using the top-side connecting piece 1A'33 as an example. Crease lines 1A'31c to 1A'32c and 1A'34c for double folding on the side are provided.

次に、天部側シート１Ａ’は、これら天部側側面１Ａ’２１～１Ａ’２４と天部側つなぎ片１Ａ’３１～１Ａ’３４とを併せた長方形の部分の外側に、底部側シート１Ｂ’と固定するヒートシール領域から成る天部側固定部１Ａ’４０を有している。 Next, the top-side sheet 1A' is placed outside the rectangular portion formed by combining the top-side side surfaces 1A'21 to 1A'24 and the top-side connecting pieces 1A'31 to 1A'34. It has a ceiling side fixing portion 1A' 40 consisting of a heat-sealed region to be fixed with 1B'.

次に、底部用シート１Ｂ’は、後述する点を除き、天部側シート１Ａ’と同様の構造を有している。すなわち、図１２に示すように、まず、底部用シート１Ｂ’は中央に長方形状の底面１Ｂ’１０を有している。この長方形状底面１Ｂ’１０は天面１Ａ’１０と同形同大である。底部用シート１Ｂ’が天部側シート１Ａ’と異なる点は、天部側シート１Ａ’の天面１Ａ’１０には、開口部１Ａ’１１が設けられているのに対し、底部用シート１Ｂ’の底面１Ｂ’１０には開口部が設けられていないことである。 Next, the bottom sheet 1B' has a structure similar to that of the top side sheet 1A' except for the points described later. That is, as shown in FIG. 12, the bottom sheet 1B' has a rectangular bottom surface 1B' 10 in the center. The rectangular bottom surface 1B'10 has the same shape and size as the top surface 1A'10. The difference between the bottom sheet 1B' and the top side sheet 1A' is that the top surface 1A'10 of the top side sheet 1A' is provided with an opening 1A'11, whereas the bottom sheet 1B' is provided with an opening 1A'11. There is no opening in the bottom surface 1B'10 of '.

また、底部用シート１Ｂ’は、多角形状の底面１Ｂ’１０の各辺を折り曲げ用罫線として、この各辺を一辺とする四角形状の底部側側面１Ｂ’２１～１Ｂ’２４を、前記長方形状底面１Ｂ’１０の辺の数と同じ４つ有している。これら底部側側面１Ｂ’２１～１Ｂ’２４も、それぞれ、天部側側面１Ａ’２１～１Ａ’２４と同形同大である。 In addition, the bottom sheet 1B' has a rectangular bottom side surface 1B'21 to 1B'24 with each side of the polygonal bottom surface 1B'10 as a ruled line for folding, and each side of the polygonal bottom surface 1B'10 as one side. It has four sides, which is the same as the number of sides of the bottom surface 1B'10. These bottom-side side surfaces 1B'21 to 1B'24 also have the same shape and size as the top-side side surfaces 1A'21 to 1A'24, respectively.

また、底部用シート１Ｂ’は、互いに隣接する各底部側側面１Ｂ’２１～１Ｂ’２４の間に、この底部側側面１Ｂ’２１～１Ｂ’２４同士を繋いでしかも閉塞する底部側つなぎ片１Ｂ’３１～１Ｂ’３４を有している。これら底部側つなぎ片１Ｂ’３１～１Ｂ’３４は天部側つなぎ片１Ａ’３１～１Ａ’３４と同形同大である。 In addition, the bottom sheet 1B' has bottom-side connecting pieces 1B between the bottom-side side surfaces 1B'21 to 1B'24 adjacent to each other to connect and close the bottom-side side surfaces 1B'21 to 1B'24. '31 to 1B'34. These bottom side connecting pieces 1B'31 to 1B'34 have the same shape and size as the top side connecting pieces 1A'31 to 1A'34.

また、各底部側側面１Ｂ’２１～１Ｂ’２４と底部側つなぎ片１Ｂ’３１～１Ｂ’３４との間には折り曲げ用罫線が設けられている。また、各底部側つなぎ片１Ｂ’３１～１Ｂ’３４には、底面１Ｂ１０の各頂点から、底部側つなぎ片１Ｂ’３１～１Ｂ’３４を二等分する底部側二つ折り用罫線１Ｂ’３１ｃ～１Ｂ’３４ｃが設けられており、この底部側二つ折り用罫線１Ｂ’３１ｃ～１Ｂ’３４ｃによって、底部側つなぎ片１Ｂ’３１～１Ｂ’３４は、それぞれ、２つの領域に区分されている。 Folding lines are provided between the bottom side side surfaces 1B'21 to 1B'24 and the bottom side connecting pieces 1B'31 to 1B'34. Further, on each of the bottom side connecting pieces 1B'31 to 1B'34, bottom side double-folding ruled lines 1B'31c to bisect the bottom side connecting pieces 1B'31 to 1B'34 from each vertex of the bottom surface 1B10. 1B'34c is provided, and the bottom side connecting pieces 1B'31 to 1B'34 are each divided into two regions by the bottom side double folding ruled lines 1B'31c to 1B'34c.

次に、底部側シート１Ｂ’は、これら底部側側面１Ｂ’２１～１Ｂ’２４と底部側つなぎ片１Ｂ’３１～１Ｂ’３４とを併せた長方形の部分の外側に、天部側シート１Ａ’と固定するヒートシール領域から成る底部側固定部１Ｂ’４０を有している。 Next, the bottom side sheet 1B' is arranged outside the rectangular portion formed by combining the bottom side side surfaces 1B'21 to 1B'24 and the bottom side connecting pieces 1B'31 to 1B'34 with the top side sheet 1A'. It has a bottom side fixing portion 1B'40 consisting of a heat-sealed area for fixing.

そして、これら天部側シート１Ａ’と底部側シート１Ｂ’とを位置合わせして重ね、両固定部１Ａ’４０，１Ｂ’４０同士をヒートシールすることにより、平坦な状態の包装容器１’を製造することができる。包装容器１’は、このように平坦な状態で保管し、また、内容物を充填密封する工程に供給することができる。 Then, the top side sheet 1A' and the bottom side sheet 1B' are aligned and overlapped, and the fixing portions 1A'40 and 1B'40 are heat-sealed to each other to form a flat packaging container 1'. can be manufactured. The packaging container 1' can thus be stored in a flat state and supplied to the process of filling and sealing the contents.

平坦状態の包装容器１’を箱型の状態に変形するためには、天部側シート１Ａ’と底部側シート１Ｂ’とのそれぞれをその折り曲げ用罫線で折り曲げて立ち上げればよい。 In order to transform the flat packaging container 1' into a box-like state, the top side sheet 1A' and the bottom side sheet 1B' are each folded along the folding ruled lines and raised.

こうして形成された箱型の状態の包装容器１’では、天部側つなぎ片１Ａ’３１～１Ａ’３４及び底部側つなぎ片１Ｂ’３１～１Ｂ’３４が、その中央に位置する天部側二つ折り用罫線１Ａ’３１ｃ～１Ａ’３４ｃと底部側二つ折り用罫線１Ｂ’３１ｃ～１Ｂ’３４ｃのいずれもが容器外面に対して山折りになるように二つ折りされたものである。この二つ折りによって、天部側シート１Ａ’の天部側側面１Ａ’２１～１Ａ’２４のうち、互い
に隣接する側面を構成する辺同士が重なり合い、また、天部側二つ折り用罫線１Ａ’３１ｃ～１Ａ’３４ｃのそれぞれによって区分された２つの領域が互いに重なり合って、フィン状パネルの天部側を構成する。図１１の拡大図を参照して天部側つなぎ片１Ａ’３３について説明すると、この天部側つなぎ片１Ａ’３３を天部側二つ折り用罫線１Ａ’３３ｃで二つ折りすることにより、この天部側つなぎ片１Ａ’３３の両側に位置する天部側側面１Ａ’２３の辺１Ａ’２３ｂと天部側側面１Ａ’２４の辺１Ａ’２４ｂとが互いに重なり合う。また、天部側二つ折り用罫線１Ａ’３３ｃで区分された２つの領域１Ａ’３３１，１Ａ’３３２が互いに重なり合って、包装容器の各角部から外側に向けて突出するフィン状パネルの天部側を構成する。 In the box-shaped packaging container 1' thus formed, the top side connecting pieces 1A'31 to 1A'34 and the bottom side connecting pieces 1B'31 to 1B'34 are arranged at the center of the top side connecting pieces 1A'31 to 1B'34. Both the folding lines 1A'31c to 1A'34c and the bottom-side double-folding lines 1B'31c to 1B'34c are folded in half so as to form a mountain fold with respect to the outer surface of the container. As a result of this double folding, the sides forming the adjacent side surfaces of the top side surfaces 1A'21 to 1A'24 of the top side sheet 1A' are overlapped with each other, and the top side double folding ruled line 1A'31c is formed. 1A'34c overlap each other to form the top side of the fin panel. Referring to the enlarged view of FIG. 11, the top side connecting piece 1A'33 will be described. The side 1A'23b of the top-side side surface 1A'23 and the side 1A'24b of the top-side side surface 1A'24 located on both sides of the portion-side connecting piece 1A'33 overlap each other. In addition, the two regions 1A'331 and 1A'332 separated by the top-side double-folding ruled line 1A'33c overlap each other, and the top of the fin-shaped panel protrudes outward from each corner of the packaging container. configure side.

ところで、平坦な状態の包装容器１’においては、天部側シート１Ａ’の天部側つなぎ片１Ａ’３３と底部側シート１Ｂ’の底部側つなぎ片１Ｂ’３３とは正確に重なり合い、その天部側二つ折り用罫線１Ａ’３３ｃと底部側二つ折り用罫線１Ｂ’３３ｃも互いに正確に重なり合っており、天部側シート１Ａ’の天部側つなぎ片１Ａ’３３を天部側二つ折り用罫線１Ａ’３３ｃで二つ折りするとき、底部側シート１Ｂ’の底部側つなぎ片１Ｂ’３３も底部側二つ折り用罫線１Ｂ’３３ｃで二つ折りされる。このため、底部側つなぎ片１Ｂ’３３の両側に位置する底部側側面１Ｂ’２３の辺１Ｂ’２３ｂと底部側側面１Ｂ２４の辺１Ｂ’２４ｂも互いに重なり合い、また、底部側二つ折り用罫線１Ｂ’３３ｃで区分された２つの領域も互いに重なり合って、包装容器の各角部から外側に向けて突出するフィン状パネル１３３’を構成する。 By the way, in the packaging container 1' in a flat state, the top-side connecting piece 1A'33 of the top-side sheet 1A' and the bottom-side connecting piece 1B'33 of the bottom-side sheet 1B' are exactly overlapped with each other. The top-side double-folding ruled line 1A'33c and the bottom-side double-folding ruled line 1B'33c are also precisely overlapped with each other, and the top-side connecting piece 1A'33 of the top-side sheet 1A' is aligned with the top-side double-folding ruled line. When the bottom side sheet 1B' is folded in half at 1A'33c, the bottom side connecting piece 1B'33 of the bottom side sheet 1B' is also folded in half at the bottom side double folding ruled line 1B'33c. Therefore, the side 1B'23b of the bottom side surface 1B'23 and the side 1B'24b of the bottom side surface 1B24 located on both sides of the bottom side connecting piece 1B'33 are also overlapped with each other, and the bottom side double-folding ruled line 1B' is formed. The two regions delimited by 33c also overlap each other to form finned panels 133' projecting outwardly from each corner of the package.

そして、天部側シート１Ａ’の天部側側面１Ａ’２３と底部側シート１Ｂ’の底部側側面１Ｂ’２３とは容器固定部１４０’を介して連続しているから、この両側面１Ａ’２３，１Ｂ’２３によって箱型の状態の包装容器１の側面１２３’が構成される。 Since the top-side side surface 1A'23 of the top-side sheet 1A' and the bottom-side side surface 1B'23 of the bottom-side sheet 1B' are continuous via the container fixing portion 140', the both side surfaces 1A' 23, 1B' and 23 constitute a side surface 123' of the packaging container 1 in a box-like state.

また、天部側シート１Ａ’の天部側つなぎ片１Ａ’３３と底部側シート１Ｂ’の底部側つなぎ片１Ｂ’３３も容器固定部１４０’を介して連続しているから、この両つなぎ片１Ａ’３３，１Ｂ’３３で構成された部分によって前記側面同士を繋いでしかも閉塞する。すなわち、天部側側面１Ａ’２３と底部側側面１Ｂ’２３とで構成される側面１２３’と、天部側側面１Ａ’２４と底部側側面１Ｂ’２４とで構成される側面１２４’との間を繋いで、しかも、ここに隙間が生じることがないように閉塞するのである。 In addition, since the top side connecting piece 1A'33 of the top side sheet 1A' and the bottom side connecting piece 1B'33 of the bottom side sheet 1B' are also continuous via the container fixing portion 140', both connecting pieces The side surfaces are connected and closed by the portion composed of 1A'33 and 1B'33. That is, a side surface 123' composed of a top side surface 1A'23 and a bottom side surface 1B'23, and a side surface 124' composed of a top side surface 1A'24 and a bottom side surface 1B'24. It connects the space and closes it so that there is no gap here.

以上、天部側つなぎ片１Ａ’３３及び底部側つなぎ片１Ｂ’３３で構成された部分を二つ折りする場合を例として説明したが、その他のつなぎ片についても同様である。 As described above, the case where the portion composed of the top-side connecting piece 1A'33 and the bottom-side connecting piece 1B'33 is folded in half has been described as an example, but the same applies to the other connecting pieces.

そして、このようにすべてのつなぎ片１Ａ’３１～１Ａ’３４，１Ｂ’３１～１Ｂ’３４を二つ折りすることにより、各側面１２１’～１２４’が形成されるから、これに伴って所定の折り曲げ用罫線で折り曲げられ、包装容器１’は箱型の形態を採る。この箱型の状態の包装容器１’は、天面１Ａ’１０と底面１Ｂ’１０とを有し、その周囲に側面１２１’～１２４’が設けられており、しかも、側面１２１’～１２４’の間をつなぎ片１Ａ’３１～１Ａ’３４，１Ｂ’３１～１Ｂ’３４が閉塞しているから、前記開口部１Ａ’１１を除いて密封された状態にある。 By folding all the connecting pieces 1A'31 to 1A'34 and 1B'31 to 1B'34 in half in this manner, the respective side surfaces 121' to 124' are formed. The packaging container 1' is folded along the folding creases, and the packaging container 1' assumes a box shape. This box-shaped packaging container 1' has a top surface 1A'10 and a bottom surface 1B'10, and side surfaces 121' to 124' are provided around the top surface 1A'10, and the side surfaces 121' to 124'. Since the connecting pieces 1A'31 to 1A'34 and 1B'31 to 1B'34 block the space between them, they are in a sealed state except for the opening 1A'11.

ところで、このように箱型の状態に変形された状態では、二つ折りされたつなぎ片１Ａ’３１～１Ａ’３４，１Ｂ’３１～１Ｂ’３４がフィン状パネル１３１’～１３４’を構成し、このフィン状パネルが包装容器１’の各角部から外側に向けて突出している。そこで、このフィン状パネル１３１’～１３４’を倒して包装容器１’の各側面１２１’～１２４’に折り重ね、例えばヒートシールして接着することによって、その外観を整えることができる。図１３はこのようにフィン状パネル１３１’～１３４’を包装容器１’の各側面１２１’～１２４’に折り重ねた状態の包装容器１’を示している。 By the way, in the state of being deformed into a box shape as described above, the folded connecting pieces 1A'31 to 1A'34 and 1B'31 to 1B'34 constitute the fin-like panels 131' to 134', This fin-like panel protrudes outward from each corner of the packaging container 1'. Therefore, the fin-like panels 131'-134' can be laid down and folded over the respective side surfaces 121'-124' of the packaging container 1', and then heat-sealed and adhered, for example, to adjust the appearance. FIG. 13 shows the packaging container 1' with the fin-like panels 131'-134' thus folded over the respective sides 121'-124' of the packaging container 1'.

ところで、フィン状パネル１３３’は、例えば、天部側つなぎ片１Ａ’３３を天部側二つ折り用罫線１Ａ’３３ｃで二つ折りして２つの領域１Ａ’３３１，１Ａ’３３２を互いに重ね合わせると共に、底部側つなぎ片１Ｂ’３３を底部側二つ折り用罫線１Ｂ’３３ｃで二つ折りして２つの領域１Ｂ’３３１，１Ｂ’３３２を互いに重ね合わせて構成されているが、天部側二つ折り用罫線１Ａ’３３ｃで区分された２つの領域１Ａ’３３１，１Ａ’３３２は互に接着されておらず、また、底部側二つ折り用罫線１Ｂ’３３ｃで区分された２つの領域１Ｂ’３３１，１Ｂ’３３２も互に接着されていない。 By the way, the fin-shaped panel 133' is formed by folding the top-side connecting piece 1A'33 in half along the top-side double-folding ruled line 1A'33c to overlap the two regions 1A'331 and 1A'332 with each other. , the bottom side connecting piece 1B'33 is folded in half along the bottom side double-folding ruled line 1B'33c, and the two regions 1B'331 and 1B'332 are overlapped with each other. The two regions 1A'331 and 1A'332 separated by the ruled line 1A'33c are not adhered to each other, and the two regions 1B'331 and 1B separated by the bottom side double-folding ruled line 1B'33c. '332 are also not glued together.

このため、領域１Ａ’３３１と領域１Ａ’３３２との間には隙間を生じ易く、また、領域１Ｂ’３３１と領域１Ｂ’３３２との間にも隙間を生じ易い。そして、このため、このフィン状パネル１３３’を倒して包装容器１’の側面に折り重ねかつヒートシールした場合であっても、領域１Ａ’３３１と領域１Ａ’３３２のうち、側面に密着しない方の領域は側面１２４’から浮き上がっていた。例えば、領域１Ａ’３３１と領域１Ａ’３３２とで構成されるフィン状パネル１３３’を倒して側面１２４’にヒートシールした場合、領域１Ａ’３３２は側面１２４’に密着して接着するが、この領域１Ａ’３３２の上に重ねられた領域１Ａ’３３１は領域１Ａ’３３２との間に隙間を生じてフィン状パネル１３３’が側面１２４’から浮き上がってしまうのである。 Therefore, a gap is likely to occur between the regions 1A' 331 and 1A' 332, and between the regions 1B' 331 and 1B' 332. For this reason, even if the fin-like panel 133' is knocked down, folded over and heat-sealed to the side surface of the packaging container 1', the one of the region 1A' 331 and the region 1A' 332 that does not come into close contact with the side surface. area was raised from the side surface 124'. For example, when the fin-like panel 133' composed of the regions 1A'331 and 1A'332 is laid down and heat-sealed to the side surface 124', the region 1A'332 is closely adhered to the side surface 124'. The area 1A' 331 superimposed on the area 1A' 332 creates a gap between the area 1A' 332 and the fin-shaped panel 133', which lifts up from the side surface 124'.

そこで、本発明は、このように包装容器の各角部から外側に向けて突出しているフィン状パネルが包装容器の各側面から浮き上がっていない包装容器を提供することを目的とする。 SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a packaging container in which the fin-like panels protruding outward from the corners of the packaging container are not lifted from the side surfaces of the packaging container.

以下、図面を参照して本発明の具体例を説明する。 Hereinafter, specific examples of the present invention will be described with reference to the drawings.

（第１の具体例）
図１～４は本発明の包装容器の第１の具体例に係り、図１及び図２は、それぞれ、その包装容器の天部側シート１Ａ及び底部側シート１Ｂを示している。 (First specific example)
1 to 4 relate to a first embodiment of the packaging container of the present invention, and FIGS. 1 and 2 respectively show a top side sheet 1A and a bottom side sheet 1B of the packaging container.

まず、天部側シート１Ａは、従来例の天部側シート１Ａ’と同様に、その中央に多角形状の天面１Ａ１０を有している。この例では、長方形状である。そして、この天面１Ａ１０には開口部１Ａ１１が設けられている。 First, the top-side sheet 1A has a polygonal top surface 1A10 in the center, like the conventional top-side sheet 1A'. In this example, it is rectangular. An opening 1A11 is provided in the top surface 1A10.

次に、天部側シート１Ａは、多角形状の天面１Ａ１０の各辺を折り曲げ用罫線として、この天面１Ａ１０の各辺を一辺とする四角形状の天部側側面１Ａ２１～１Ａ２４を有している。天部側側面１Ａ２１～１Ａ２４の数は、多角形状天面１Ａ１０の辺の数と同じであ
る。この例では天面１Ａ１０は四角形状であるから、この四角形状天面１Ａ１０の辺の数は４であり、天部側側面１Ａ２１～１Ａ２４の数も４である。 Next, the top-side sheet 1A has quadrangular top-side side surfaces 1A21 to 1A24 with each side of a polygonal top surface 1A10 as a ruled line for folding. there is The number of side surfaces 1A21 to 1A24 on the top side is the same as the number of sides of the polygonal top surface 1A10. In this example, since the top surface 1A10 is square, the square top surface 1A10 has four sides and four side surfaces 1A21 to 1A24.

また、天部側シート１Ａは、互いに隣接する各天部側側面の間に、この天部側側面１Ａ２１～１Ａ２４同士を繋ぐ天部側つなぎ片１Ａ３１～１Ａ３４を有している。すなわち、天部側側面１Ａ２１と天部側側面１Ａ２２との間は天部側つなぎ片１Ａ３１で繋がれている。また、天部側側面１Ａ２２と天部側側面１Ａ２３との間は天部側つなぎ片１Ａ３２で繋がれている。その他の天部側側面についても同様である。なお、各天部側側面１Ａ２１～１Ａ２４と天部側つなぎ片１Ａ３１～１Ａ３４との間には折り曲げ用罫線が設けられている。 Further, the top-side sheet 1A has top-side connecting pieces 1A31 to 1A34 that connect the top-side side surfaces 1A21 to 1A24 between the mutually adjacent top-side side surfaces. That is, the top-side connecting piece 1A31 connects the top-side side surface 1A21 and the top-side side surface 1A22. Moreover, the top-side side surface 1A22 and the top-side side surface 1A23 are connected by a top-side connecting piece 1A32. The same applies to the other side surfaces on the top side. Folding lines are provided between the top side side surfaces 1A21 to 1A24 and the top side connecting pieces 1A31 to 1A34.

そして、この天部側つなぎ片１Ａ３１～１Ａ３４によって、天部側側面１Ａ２１～１Ａ２４の間は閉塞されている。図示のように、この例では、天部側側面１Ａ２１～１Ａ２４と天部側つなぎ片１Ａ３１～１Ａ３４とを併せた部分の外形は長方形を構成しており、各天部側つなぎ片１Ａ３１～１Ａ３４はその角部に位置して、天部側側面１Ａ２１～１Ａ２４の間を閉塞している。例えば、天部側側面１Ａ２１と天部側側面１Ａ２２との間は天部側つなぎ片１Ａ３１で閉塞している。 The top side connecting pieces 1A31 to 1A34 close the top side side surfaces 1A21 to 1A24. As shown in the figure, in this example, the combined shape of the top-side side surfaces 1A21-1A24 and the top-side connecting pieces 1A31-1A34 constitutes a rectangle, and the top-side connecting pieces 1A31-1A34 are It is positioned at the corner and closes the space between the side surfaces 1A21 to 1A24 on the top side. For example, the space between the top side surface 1A21 and the top side surface 1A22 is blocked by the top side connecting piece 1A31.

この天部側つなぎ片１Ａ３１～１Ａ３４は、天面１Ａ１０の各頂点から、天部側つなぎ片１Ａ３１～１Ａ３４を二等分する天部側二つ折り用罫線を有している。すなわち、図１に拡大して示すように、例えば、天部側側面１Ａ２３と天部側側面１Ａ２４とは、天面１Ａ１０の頂点１Ａ１０ｂを共有している。天部側側面１Ａ２３を構成する辺のうち、天面１Ａ１０の頂点１Ａ１０ｂを共有している辺には、符号１Ａ２３ｂを付して示している。また、天部側側面１Ａ２４を構成する辺のうち、天面１Ａ１０の頂点１Ａ１０ｂを共有している辺には、符号１Ａ２４ｂを付して示している。そして、この辺１Ａ２３ｂと辺１Ａ２４ｂとがなす角を二等分する天部側二つ折り用罫線１Ａ３３ｃが設けられ、この天部側二つ折り用罫線１Ａ３３ｃによって、天部側つなぎ片１Ａ３３は２つの領域１Ａ３３１，１Ａ３３２に区分されている。すなわち、図において、辺１Ａ２３ｂと二つ折り用罫線１Ａ３３ｃとがなす角θ１と、辺１Ａ２４ｂと天部側二つ折り用罫線１Ａ３３ｃとがなす角θ２とは等しく、領域１Ａ３３１と領域１Ａ３３２とは、同形同大で、しかも、天部側二つ折り用罫線１Ａ３３ｃを対称軸として線対称に配置されている。 The top-side connecting pieces 1A31 to 1A34 have crease lines for bi-folding the top-side connecting pieces 1A31 to 1A34 from each vertex of the top surface 1A10. That is, as shown enlarged in FIG. 1, for example, the top side surface 1A23 and the top side surface 1A24 share the vertex 1A10b of the top surface 1A10. Among the sides forming the top-side side surface 1A23, the sides sharing the vertex 1A10b of the top surface 1A10 are denoted by reference numeral 1A23b. Further, among the sides forming the top side surface 1A24, the side sharing the vertex 1A10b of the top surface 1A10 is denoted by reference numeral 1A24b. A top-side double-folding ruled line 1A33c is provided to bisect the angle formed by the side 1A23b and the side 1A24b. , 1A332. That is, in the figure, the angle θ1 formed by side 1A23b and double-folding ruled line 1A33c is equal to the angle θ2 formed by side 1A24b and top-side double-folding ruled line 1A33c, and region 1A331 and region 1A332 are of the same shape. They are of the same size and arranged line-symmetrically with the top-side double-folding ruled line 1A33c as the axis of symmetry.

以上天部側つなぎ片１Ａ３３を例として天部側二つ折り用罫線１Ａ３３ｃについて説明したが、その他の天部側つなぎ片１Ａ３１～１Ａ３２，１Ａ３４にも同様に天部側二つ折り用罫線１Ａ３１ｃ～１Ａ３２ｃ，１Ａ３４ｃが設けられており、また、それぞれ、２つの領域に区分されている。すなわち、天部側つなぎ片１Ａ３１は、天部側二つ折り用罫線１Ａ３１ｃによって同形同大かつ線対称に配置された領域１Ａ３１１と領域１Ａ３１２に区分されている。また、天部側つなぎ片１Ａ３２は、天部側二つ折り用罫線１Ａ３２ｃによって同形同大かつ線対称に配置された領域１Ａ３２１と領域１Ａ３２２に区分されている。また、天部側つなぎ片１Ａ３４は、天部側二つ折り用罫線１Ａ３４ｃによって同形同大かつ線対称に配置された領域１Ａ３４１と領域１Ａ３４２に区分されている。なお、煩雑さを避けるため、図１ではこれらの符号の図示を省略している。 The top-side double-folding ruled line 1A33c has been described above using the top-side connecting piece 1A33 as an example. 1A34c are provided and are each partitioned into two regions. That is, the top-side connecting piece 1A31 is divided into areas 1A311 and 1A312 of the same shape and size and line-symmetrically arranged by the top-side double-folding ruled line 1A31c. In addition, the top side connecting piece 1A32 is divided into areas 1A321 and 1A322 of the same shape and size and line-symmetrically arranged by the top side double-folding ruled line 1A32c. In addition, the top side connecting piece 1A34 is divided into areas 1A341 and 1A342 of the same shape and size and line-symmetrically arranged by the top side double-folding ruled line 1A34c. In order to avoid complication, illustration of these symbols is omitted in FIG.

次に、天部側シート１Ａは、これら天部側側面１Ａ２１～１Ａ２４と天部側つなぎ片１Ａ３１～１Ａ３４とを併せた長方形の部分の外側に、底部側シート１Ｂと固定する天部側固定部１Ａ４０を有している。この例では、天部側固定部１Ａ４０は、全周にわたってヒートシール領域で構成しているが、後述する第３の変形例のように、天部側シート１Ａと底部側シート１Ｂの両者を１枚のシートで構成する場合には、天部側固定部１Ａ４０の一部を天部側シート１Ａと底部側シート１Ｂとを区画する折り曲げ用罫線１ＡＢで構成することも可能である。 Next, the top-side sheet 1A is provided with a top-side fixing portion that is fixed to the bottom-side sheet 1B on the outside of the rectangular portion formed by combining the top-side side surfaces 1A21 to 1A24 and the top-side connecting pieces 1A31 to 1A34. It has 1A40. In this example, the top-side fixing portion 1A40 is configured with a heat-sealed region over the entire circumference. In the case of a single sheet, a part of the top-side fixed portion 1A40 can be formed by the folding ruled line 1AB that separates the top-side sheet 1A and the bottom-side sheet 1B.

なお、図１においては、天部側固定部１Ａ４０を区分して、天部側側面１Ａ２１に対応する部分の天部側固定部、すなわち、天部側側面１Ａ２１の外側に位置する天部側固定部に「１Ａ４１」の符号を付して図示している。同様に、天部側側面１Ａ２２に対応する部分の天部側固定部には「１Ａ４２」の符号を付し、天部側側面１Ａ２３に対応する部分の天部側固定部には「１Ａ４３」の符号を付し、天部側側面１Ａ２４に対応する部分の天部側固定部には「１Ａ４４」の符号を付している。 In FIG. 1, the top side fixing portion 1A40 is divided, and the top side fixing portion corresponding to the top side side surface 1A21, that is, the top side fixing portion located outside the top side side surface 1A21 1A41 is attached to the part. Similarly, the top-side fixing portion corresponding to the top-side side surface 1A22 is denoted by "1A42", and the top-side fixing portion corresponding to the top-side side surface 1A23 is denoted by "1A43". Reference numerals are attached, and the reference numeral "1A44" is attached to the top portion side fixing portion corresponding to the top portion side surface 1A24.

また、天部側側面１Ａ２１の両側には天部側つなぎ片１Ａ３１，１Ａ３４が配置されているが、この天部側つなぎ片１Ａ３４を前記天部側二つ折り用罫線１Ａ３４ｃによって区分して設けられた２つの領域１Ａ３４１，１Ａ３４２のうち、天部側側面１Ａ２１に隣接する領域１Ａ３４２に対応する部分の天部側固定部、すなわち、領域１Ａ３４２の外側に位置する天部側固定部に「１Ａ４１α」の符号を付して図示している。また、前記天部側つなぎ片１Ａ３１を前記天部側二つ折り用罫線１Ａ３１ｃによって区分して設けられた２つの領域１Ａ３１１，１Ａ３１２のうち、天部側側面１Ａ２１に隣接する領域１Ａ３１１に対応する部分の天部側固定部、すなわち、領域１Ａ３１１の外側に位置する天部側固定部に「１Ａ４１β」の符号を付して図示している。 Also, the top side connecting pieces 1A31 and 1A34 are arranged on both sides of the top side surface 1A21, and the top side connecting piece 1A34 is divided by the top side double-folding ruled line 1A34c. Of the two regions 1A341 and 1A342, the top-side fixing portion of the portion corresponding to the region 1A342 adjacent to the top-side side surface 1A21, that is, the top-side fixing portion positioned outside the region 1A342 is labeled with "1A41α". is attached and illustrated. In addition, of the two regions 1A311 and 1A312 provided by separating the top-side connecting piece 1A31 by the top-side double-folding ruled line 1A31c, the portion corresponding to the region 1A311 adjacent to the top-side side surface 1A21. The top-side fixing portion, that is, the top-side fixing portion positioned outside the region 1A311 is illustrated with the reference numeral "1A41β".

なお、図１においては、天部側固定部１Ａ４０と天部側側面１Ａ２１～１Ａ２４との境界、及び天部側固定部１Ａ４０と天部側つなぎ片１Ａ３１～１Ａ３４との境界を破線によって示しているが、これらは説明の便宜のために施したものである。後述する底部側シート１Ｂの底部側固定部１Ｂ４０と底部側側面１Ｂ２１～１Ｂ２４との境界と異なり、天部側固定部１Ａ４０と天部側側面１Ａ２１～１Ａ２４との境界には折り曲げ用罫線は存在しない。天部側固定部１Ａ４０と天部側つなぎ片１Ａ３１～１Ａ３４との境界にも折り曲げ用罫線は存在しない。 In FIG. 1, the boundaries between the top side fixing portion 1A40 and the top side side surfaces 1A21 to 1A24 and the boundaries between the top side fixing portion 1A40 and the top side connecting pieces 1A31 to 1A34 are indicated by dashed lines. However, these are given for convenience of explanation. Unlike the boundaries between the bottom-side fixing portion 1B40 and the bottom-side side surfaces 1B21 to 1B24 of the bottom-side sheet 1B, which will be described later, there are no folding lines on the boundaries between the top-side fixing portion 1A40 and the top-side side surfaces 1A21 to 1A24. . There is also no folding ruled line on the boundary between the top fixing portion 1A40 and the top connecting pieces 1A31 to 1A34.

次に、天部側つなぎ片１Ａ３３の位置において前記天部側固定部の外側に前記二つ折り用罫線被覆片１Ａ５４αが設けられており、しかも、前記天部側つなぎ片１Ａ３３を構成する二つの領域１Ａ３３１，１Ａ３３２のうち一方の領域１Ａ３３２に対応する位置の天部側固定部１Ａ４４αの外側に選択的に前記二つ折り用罫線被覆片１Ａ５４αが設けられており、他方の領域１Ａ３３１に対応する位置の天部側固定部１Ａ４３βの外側には二つ折り用罫線被覆片が設けられていない。このため、天部側つなぎ片１Ａ３３を天部側二つ折り用罫線１Ａ３３ｃで二つ折りして領域１Ａ３３１，１Ａ３３２を互に重ね合わせてフィン状パネルの天部側を形成したとき、二つ折り用罫線被覆片１Ａ５４αは領域１Ａ３３１の端縁から突出する。そして、この二つの領域１Ａ３３１，１Ａ３３２のうち領域１Ａ３３１が包装容器１の側面１Ａ２３に密着し、領域１Ａ３３２がその外面側に位置するように前記フィン状パネルを倒して側面１Ａ２３に重ね合わせると、二つ折り用罫線被覆片１Ａ５４αがこのフィン状パネルの端面を被覆して、この端面が包装容器１の外面に露出することを防ぐことができる。そして、このため、二つ折り用罫線被覆片１Ａ５４αを側面１Ａ２３に接着することにより、フィン状パネルが包装容器１の側面１Ａ２３から浮き上がることを防止する。 Next, at the position of the top-side connecting piece 1A33, the double-folding ruled line covering piece 1A54α is provided outside the top-side fixing portion, and two regions constituting the top-side connecting piece 1A33. The double-folding ruled line covering piece 1A54α is selectively provided outside the top side fixing portion 1A44α at a position corresponding to one region 1A332 of 1A331 and 1A332, and the top at a position corresponding to the other region 1A331. No double-folding ruled line covering piece is provided on the outer side of the part-side fixing portion 1A43β. Therefore, when the top side connecting piece 1A33 is folded in half along the top side double-folding ruled line 1A33c and the regions 1A331 and 1A332 are superimposed on each other to form the top side of the fin-like panel, the double-folding ruled line covering is applied. Piece 1A54α protrudes from the edge of region 1A331. Of these two regions 1A331 and 1A332, the region 1A331 is in close contact with the side surface 1A23 of the packaging container 1, and the region 1A332 is located on the outer surface side. The folding ruled line covering piece 1A54α covers the end face of the fin-like panel, and the end face can be prevented from being exposed to the outer surface of the packaging container 1. For this reason, the fin-shaped panel is prevented from rising from the side surface 1A23 of the packaging container 1 by adhering the double-folding ruled line covering piece 1A54α to the side surface 1A23.

なお、この二つ折り用罫線被覆片１Ａ５４αを側面１２３に接着することによってフィン状パネルと側面１Ａ２３との隙間を完全に防止する必要はない。両者の間にわずかな隙間があっても、フィン状パネルが包装容器１の側面１２３から浮き上がることを防止することができるのである。 Note that it is not necessary to completely prevent the gap between the fin-shaped panel and the side surface 1A23 by adhering the creased line covering piece 1A54α for folding in half to the side surface 123. Even if there is a slight gap between the two, it is possible to prevent the fin-shaped panel from rising from the side surface 123 of the packaging container 1 .

ところで、このように二つ折り用罫線被覆片が設けられた位置に対応する天部側つなぎ片を被覆片対応天部側つなぎ片と呼ぶとき、この第１の具体例では、天部側側面１Ａ２４の両側の天部側つなぎ片１Ａ３３，１Ａ３４がこの被覆片対応天部側つなぎ片を構成して
いる。すなわち、前述のように、まず、天部側つなぎ片１Ａ３３を構成する二つの領域１Ａ３３１，１Ａ３３２のうち天部側側面１Ａ２４に隣接する領域１Ａ３３２に対応する位置に選択的に前記二つ折り用罫線被覆片１Ａ５４αが設けられており、他方の領域１Ａ３３１に対応する位置には二つ折り用罫線被覆片が設けられていない。また、天部側つなぎ片１Ａ３４を構成する二つの領域１Ａ３４１，１Ａ３４２のうち天部側側面１Ａ２４に隣接する領域１Ａ３４１に対応する位置に選択的に前記二つ折り用罫線被覆片１Ａ５４βが設けられており、他方の領域１Ａ３４２に対応する位置には二つ折り用罫線被覆片が設けられていない。 By the way, when the top side connecting piece corresponding to the position where the double-folding ruled line covering piece is provided is called the covering piece corresponding top side connecting piece, in this first specific example, the top side surface 1A24 The top side connecting pieces 1A33 and 1A34 on both sides of the cover piece constitute the covering piece corresponding top side connecting pieces. That is, as described above, first, of the two regions 1A331 and 1A332 forming the top-side connecting piece 1A33, the two-fold ruled line covering is selectively applied to a position corresponding to the region 1A332 adjacent to the top-side side surface 1A24. A piece 1A54α is provided, and no double-folding ruled line cover piece is provided at a position corresponding to the other region 1A331. Further, the double-folding ruled line covering piece 1A54β is selectively provided at a position corresponding to the region 1A341 adjacent to the top side surface 1A24 of the two regions 1A341 and 1A342 forming the top side connecting piece 1A34. , and the other area 1A342 is not provided with a covering piece for folding ruled lines.

次に、この第１の具体例では、天部側側面１Ａ２４の位置において前記天部側固定部１Ａ４４の外側に固定部端面被覆片１Ａ５４が設けられている。後述するように、この固定部端面被覆片１Ａ５４は、包装容器１を箱型の状態としたとき、天部側固定部１Ａ４４と底部側固定部１Ｂ４４とが重ね合わされて構成された固定部の端面を被覆して、この端面が包装容器１外面に露出することを防ぐものである。 Next, in this first specific example, a fixing portion end surface covering piece 1A54 is provided outside the top portion side fixing portion 1A44 at the position of the top portion side surface 1A24. As will be described later, the fixing portion end surface covering piece 1A54 is formed by superimposing the top side fixing portion 1A44 and the bottom side fixing portion 1B44 when the packaging container 1 is in a box shape. is covered to prevent this end surface from being exposed to the outer surface of the packaging container 1 .

なお、固定部端面被覆片１Ａ５４と二つ折り用罫線被覆片１Ａ５４α，１Ａ５４βが互いに連接されている必要はないが、これらは折り曲げ用罫線を介して互いに連接されていることが望ましい。この例では、図示のように、固定部端面被覆片１Ａ５４と二つ折り用罫線被覆片１Ａ５４αとは折り曲げ用罫線を介して互いに連接されており、また、固定部端面被覆片１Ａ５４と二つ折り用罫線被覆片１Ａ５４βも互いに連接されている。 Although the fixing portion end surface covering piece 1A54 and the folding ruled line covering pieces 1A54α and 1A54β need not be connected to each other, it is desirable that they are connected to each other via the folding ruled lines. In this example, as shown in the figure, the fixed portion end surface covering piece 1A54 and the double-folding ruled line covering piece 1A54α are connected to each other via the folding ruled line, and the fixed portion end surface covering piece 1A54 and the double-folding ruled line are connected to each other. The covering pieces 1A54β are also connected to each other.

ところで、こうして両側の天部側つなぎ片が被覆片対応天部側つなぎ片を構成している天部側側面を被覆片対応天部側側面と呼ぶとき、この第１の具体例では、被覆片対応天部側側面はただ一つで、天部側側面１Ａ２４がこの被覆片対応天部側側面に該当するが、後述する第１の具体例の第２の変形例及び第３の変形例に示すように、複数の被覆片対応天部側側面を有していてもよい。このように複数の被覆片対応天部側側面を有する場合には、もちろん、それぞれの被覆片対応天部側側面の両側の天部側つなぎ片は、二つ折り用罫線被覆片を有する被覆片対応天部側つなぎ片を構成する。被覆片対応天部側側面が包装容器の周方向に１つ置きに配置されているとき、すべての天部側つなぎ片が被覆片対応天部側つなぎ片を構成することとなる。 By the way, when the top-side side surfaces on which the top-side connecting pieces on both sides constitute the covering-piece corresponding top-side connecting pieces are called covering-piece-corresponding top-side surfaces, in this first specific example, the covering pieces There is only one corresponding top-side side surface, and the top-side side surface 1A24 corresponds to this covering piece corresponding top-side side surface. As shown, it may have a plurality of top side surfaces corresponding to the covering pieces. In the case of having a plurality of covering piece-corresponding top-side surfaces, of course, the top-side connecting pieces on both sides of each covering-piece corresponding top-side surface correspond to the covering pieces having the double-fold ruled-line covering pieces. It constitutes a top-side connecting piece. When the top-side side surfaces corresponding to the covering pieces are arranged alternately in the circumferential direction of the packaging container, all the top-side joint pieces constitute the top-side joint pieces corresponding to the covering pieces.

なお、図１中、天部側固定部１Ａ４０に設けられた切り欠け１Ａ４ｘは、天部側シート１Ａと底部側シート１Ｂとを重ね合わせる際の位置合わせマークである。両シート１Ａ，１Ｂを正確に位置合わせするため、この欠け１Ａ４ｘは２以上設けられていることが望ましい。この例では、4箇所（天部側固定部１Ａ４１α，１Ａ４１β，１Ａ４３α，１Ａ４３β）に設けられている。 In FIG. 1, the notch 1A4x provided in the top-side fixing portion 1A40 is an alignment mark when the top-side sheet 1A and the bottom-side sheet 1B are superimposed. In order to accurately align both sheets 1A and 1B, it is desirable to provide two or more of these notches 1A4x. In this example, they are provided at four locations (top side fixing portions 1A41α, 1A41β, 1A43α, 1A43β).

次に、図２を参照して底部用シート１Ｂについて説明する。底部用シート１Ｂは従来の底部用シート１Ｂ’と同様であってよい。この第１の具体例では、位置合わせ用の切り欠け１Ｂ４ｘを有するほかは従来の底部用シート１Ｂ’と同様であり、また、後述する３つの点を除き、天部側シート１Ａと同様の構造を有している。すなわち、まず、底部用シート１Ｂは中央に多角形状の底面１Ｂ１０を有している。この多角形状底面１Ｂ１０は天面１Ａ１０と同形である。底部用シート１Ｂが天部側シート１Ａと異なる第１の点は、天部側シート１Ａの天面１Ａ１０には、開口部が設けられているのに対し、底部用シート１Ｂの底面１Ｂ１０には開口部が設けられていないことである。 Next, the bottom sheet 1B will be described with reference to FIG. The bottom sheet 1B may be similar to the conventional bottom sheet 1B'. This first specific example has the same structure as the conventional bottom sheet 1B' except for having a notch 1B4x for alignment, and also has the same structure as the top side sheet 1A except for three points described later. have. First, the bottom sheet 1B has a polygonal bottom surface 1B10 in the center. The polygonal bottom surface 1B10 has the same shape as the top surface 1A10. The first difference between the bottom sheet 1B and the top-side sheet 1A is that the top surface 1A10 of the top-side sheet 1A is provided with an opening, whereas the bottom surface 1B10 of the bottom-side sheet 1B is provided with an opening. There is no opening.

また、底部用シート１Ｂは、多角形状の底面１Ｂ１０の各辺を折り曲げ用罫線として、この各辺を一辺とする四角形状の底部側側面１Ｂ２１～１Ｂ２４を、前記多角形状底面１Ｂ１０の辺の数と同じ数だけ有している。これら底部側側面１Ｂ２１～１Ｂ２４も、それぞれ、天部側側面１Ａ２１～１Ａ２４と同形である。 In addition, the bottom sheet 1B uses each side of the polygonal bottom surface 1B10 as a ruled line for folding, and the square bottom side surfaces 1B21 to 1B24 having each side as one side is the number of sides of the polygonal bottom surface 1B10. have the same number. These bottom-side side surfaces 1B21 to 1B24 also have the same shape as the top-side side surfaces 1A21 to 1A24, respectively.

また、底部用シート１Ｂは、互いに隣接する各底部側側面１Ｂ２１～１Ｂ２４の間に、この底部側側面１Ｂ２１～１Ｂ２４同士を繋いでしかも閉塞する底部側つなぎ片１Ｂ３１～１Ｂ３４を有している。これら底部側つなぎ片１Ｂ３１～１Ｂ３４は天部側つなぎ片１Ａ３１～１Ａ３４と同形同大である。 Further, the bottom sheet 1B has bottom side connecting pieces 1B31 to 1B34 between the bottom side side surfaces 1B21 to 1B24 adjacent to each other to connect and block the bottom side side surfaces 1B21 to 1B24. These bottom side connecting pieces 1B31 to 1B34 have the same shape and size as the top side connecting pieces 1A31 to 1A34.

また、各底部側側面１Ｂ２１～１Ｂ２４と底部側つなぎ片１Ｂ３１～１Ｂ３４との間には折り曲げ用罫線が設けられている。また、各底部側つなぎ片１Ｂ３１～１Ｂ３４には、底面１Ｂ１０の各頂点から、底部側つなぎ片１Ｂ３１～１Ｂ３４を二等分する底部側二つ折り用罫線１Ｂ３１ｃ～１Ｂ３４ｃが設けられており、この底部側二つ折り用罫線１Ｂ３１ｃ～１Ｂ３４ｃによって、底部側つなぎ片１Ｂ３１～１Ｂ３４は、それぞれ、２つの領域に区分されている。 In addition, creases for folding are provided between the bottom side side surfaces 1B21 to 1B24 and the bottom side connecting pieces 1B31 to 1B34. Each of the bottom side connecting pieces 1B31 to 1B34 is provided with bottom side double-folding creases 1B31c to 1B34c that bisect the bottom side connecting pieces 1B31 to 1B34 from each vertex of the bottom surface 1B10. The bottom side connecting pieces 1B31 to 1B34 are each divided into two regions by the double-folding ruled lines 1B31c to 1B34c.

次に、底部側シート１Ｂは、これら底部側側面１Ｂ２１～１Ｂ２４と底部側つなぎ片１Ｂ３１～１Ｂ３４とを併せた長方形の部分の外側に、天部側シート１Ａと固定する底部側固定部１Ｂ４０を有している。この例では、底部側固定部１Ｂ４０は、全周にわたってヒートシール領域である。 Next, the bottom side sheet 1B has a bottom side fixing portion 1B40 to be fixed to the top side sheet 1A outside the rectangular portion formed by combining the bottom side side surfaces 1B21 to 1B24 and the bottom side connecting pieces 1B31 to 1B34. are doing. In this example, the bottom side fixing portion 1B40 is a heat-sealed area over the entire circumference.

なお、底部側シート１Ｂの底部側固定部１Ｂ４０と底部側側面１Ｂ２１～１Ｂ２４との境界、及び底部側固定部１Ｂ４０と底部側つなぎ片１Ｂ３１～１Ｂ３４との境界には折り曲げ用罫線が設けられている。天部側シート１Ａの天部側固定部１Ａ４０の境界には折り曲げ用罫線が存在しないから、この点が底部用シート１Ｂと天部側シート１Ａとの第２の相違点である。そして、このように底部側シート１Ｂには折り曲げ用罫線が設けられており、天部側シート１Ａには存在しないから、この両シート１Ａ，１Ｂを重ねて固定し、箱型の状態としたとき、互いに固定された両固定部１Ａ４０，１Ｂ４０は折り曲げ用罫線１Ｂｘによって底部側シート１Ｂ側に折り曲げられ、その外側に天部側シート１Ａが重ねられることになる。なお、前述のように、天部側側面１Ａ２４の位置において前記天部側固定部１Ａ４４の外側には固定部端面被覆片１Ａ５４が設けられているから、天部側固定部１Ａ４４と底部側固定部１Ｂ４４とが重ね合わされて構成された固定部の端面を被覆して、この端面が包装容器１外面に露出することを防ぐことができる。 Bending ruled lines are provided on the boundary between the bottom side fixed portion 1B40 of the bottom side sheet 1B and the bottom side side surfaces 1B21 to 1B24 and on the boundary between the bottom side fixed portion 1B40 and the bottom side connecting pieces 1B31 to 1B34. . Since there is no folding ruled line at the boundary of the top-side fixing portion 1A40 of the top-side sheet 1A, this point is the second difference between the bottom-side sheet 1B and the top-side sheet 1A. As described above, the bottom side sheet 1B is provided with creases for folding, and the top side sheet 1A does not have creases for folding. Both fixed portions 1A40 and 1B40 fixed to each other are folded toward the bottom side sheet 1B along the folding ruled line 1Bx, and the top side sheet 1A is superimposed on the outside thereof. In addition, as described above, since the fixing portion end face covering piece 1A54 is provided outside the top fixing portion 1A44 at the position of the top side surface 1A24, the top fixing portion 1A44 and the bottom fixing portion 1B44 are overlapped to cover the end surface of the fixing portion, and the end surface can be prevented from being exposed to the outer surface of the packaging container 1 .

なお、底部側固定部１Ｂ４０にも、位置合わせ用切り欠け１Ｂ４ｘが設けられている。この位置合わせ用切り欠け１Ｂ４ｘは、天部側シート１Ａと底部用シート１Ｂとを重ね合わせたとき、天部側固定部１Ａ４０の位置合わせ用切り欠け１Ａ４ｘに重ね合わせる位置に配置されていることが望ましい。この例では、天部側固定部１Ａ４０の位置合わせ用切り欠け１Ａ４ｘの数が4箇所（天部側固定部１Ａ４１α，１Ａ４１β，１Ａ４３α，１Ａ４３β）なので、底部側固定部１Ｂ４０の位置合わせ用切り欠け１Ｂ４ｘも4箇所（底部側固定部１Ｂ４１α，１Ｂ４１β，１Ｂ４３α，１Ｂ４３β）である。 Note that the bottom-side fixing portion 1B40 is also provided with an alignment notch 1B4x. This alignment notch 1B4x is arranged at a position where it overlaps with the alignment notch 1A4x of the top-side fixing portion 1A40 when the top-side sheet 1A and the bottom-side sheet 1B are overlapped. desirable. In this example, the number of alignment notches 1A4x of the top side fixing part 1A40 is four (top side fixing parts 1A41α, 1A41β, 1A43α, 1A43β), so the alignment notch 1B4x of the bottom side fixing part 1B40 4 (bottom side fixing portions 1B41α, 1B41β, 1B43α, 1B43β).

次に、図３を参照して、平坦な状態の包装容器１を製造する方法を説明する。すなわち、天部側シート１Ａと底部側シート１Ｂとを位置合わせして重ね、両固定部１Ａ４０，１Ｂ４０同士をヒートシールすることにより、平坦な状態の包装容器１を製造することができる。 Next, with reference to FIG. 3, a method for manufacturing the flat packaging container 1 will be described. That is, the flat packaging container 1 can be manufactured by aligning the top side sheet 1A and the bottom side sheet 1B, overlapping them, and heat-sealing the fixing portions 1A40 and 1B40.

このとき、図３（ａ）から分かるように、天部側側面１Ａ２４の外側に位置する天部側固定部１Ａ４４と底部側側面１Ｂ２４の外側に位置する底部側固定部１Ｂ４４とが互いにヒートシールされ、天部側固定部１Ａ４４の外側に位置する固定部端面被覆片１Ａ５４がこれら天部側固定部１Ａ４４及び底部側固定部１Ｂ４４の端縁から突出する。 At this time, as can be seen from FIG. 3A, the top fixing portion 1A44 located outside the top side surface 1A24 and the bottom fixing portion 1B44 located outside the bottom side surface 1B24 are heat-sealed to each other. , the fixing portion end surface covering piece 1A54 located outside the top side fixing portion 1A44 protrudes from the edges of the top side fixing portion 1A44 and the bottom side fixing portion 1B44.

また、同様に図３（ｂ）から分かるように、天部側つなぎ片１Ａ３３を構成する二つの
領域１Ａ３３１，１Ａ３３２のうち天部側側面１Ａ２４に隣接する領域１Ａ３３２の外側に位置する天部側固定部１Ａ４４αと、これに対応する底部側固定部１Ｂ４４αとが互いにヒートシールされ、天部側固定部１Ａ４４αの外側に位置する二つ折り用罫線被覆片１Ａ５４αがこれら天部側固定部１Ａ４４α及び底部側固定部１Ｂ４４αの端縁から突出する。いっぽう、図示を省略するが、天部側つなぎ片１Ａ３３を構成する二つの領域１Ａ３３１，１Ａ３３２のうち天部側側面１Ａ２４に隣接しない領域１Ａ３３１の外側には二つ折り用罫線被覆片は設けられておらず、もちろん、天部側固定部１Ａ４３β及び底部側固定部１Ｂ４３βの端縁から突出することもない。このため、天部側つなぎ片１Ａ３３を二つ折り用罫線１Ａ３３ｃで二つ折りすると、領域１Ａ３３１と領域１Ａ３３２とが互いに重ね合わされ、領域１Ａ３３２から突出する二つ折り用罫線被覆片１Ａ５４αが領域１Ａ３３１及び領域１Ａ３３２の外側の天部側固定部１Ａ４３β，１Ａ４４αの端縁から突出する。一方、底部側つなぎ片１Ｂ３３を二つ折り用罫線１Ｂ３３ｃで二つ折りすると、領域１Ｂ３３１と領域１Ｂ３３２とが互いに重ね合わされる。このように二つ折り用罫線１Ａ３３ｃ及び１Ｂ３３ｃで天部側つなぎ片１Ａ３３及び底部側つなぎ片１Ｂ３３を二つ折りすることにより、領域１Ａ３３１と領域１Ａ３３２とが互いに重ね合わされた部分及び領域１Ｂ３３１と領域１Ｂ３３２とが互いに重ね合わされた部分によってフィン状パネル１３３を形成することができる。そして、このフィン状パネル１３３の天部側においては二つ折り用罫線被覆片１Ａ５４αが突出しているから、この二つ折り用罫線被覆片１Ａ５４αが包装容器１の外面側となるように倒すことにより、この二つ折り用罫線被覆片１Ａ５４αによって二つ折り用罫線１Ｂ３３ｃを被覆することができる。 Similarly, as can be seen from FIG. 3(b), of the two regions 1A331 and 1A332 forming the top-side connecting piece 1A33, the top-side fixing portion located outside the region 1A332 adjacent to the top-side side surface 1A24 The portion 1A44α and the corresponding bottom side fixing portion 1B44α are heat-sealed to each other, and the double-folding ruled line covering piece 1A54α located outside the top side fixing portion 1A44α is fixed to the top side fixing portion 1A44α and the bottom side fixing portion. It protrudes from the edge of the portion 1B44α. On the other hand, although not shown in the drawings, of the two regions 1A331 and 1A332 forming the top side connecting piece 1A33, the outside of the region 1A331 that is not adjacent to the top side side surface 1A24 is not provided with a double-folding ruled line covering piece. of course, it does not protrude from the edges of the top-side fixing portion 1A43β and the bottom-side fixing portion 1B43β. Therefore, when the top-side connecting piece 1A33 is folded in half along the double-folding ruled line 1A33c, the area 1A331 and the area 1A332 overlap each other, and the double-folding ruled-line covering piece 1A54α protruding from the area 1A332 overlaps the area 1A331 and the area 1A332. It protrudes from the edges of the outer top side fixing portions 1A43β and 1A44α. On the other hand, when the bottom side connecting piece 1B33 is folded in half along the folding ruled line 1B33c, the area 1B331 and the area 1B332 overlap each other. By folding the top-side connecting piece 1A33 and the bottom-side connecting piece 1B33 in half along the crease lines 1A33c and 1B33c for folding in half in this manner, a portion in which the regions 1A331 and 1A332 overlap each other and the regions 1B331 and 1B332 are formed. A finned panel 133 can be formed by the overlapping portions. Since the double-folding ruled line covering piece 1A54α protrudes from the top side of the fin-shaped panel 133, by laying down the double-folding ruled line covering piece 1A54α to face the outer surface of the packaging container 1, this The double-folding ruled line 1B33c can be covered with the double-folding ruled line covering piece 1A54α.

次に、平坦な状態の包装容器１を箱型の状態に変形する方法を説明する。このためには、天部側つなぎ片１Ａ３１～１Ａ３４及び底部側つなぎ片１Ｂ３１～１Ｂ３４を、その中央に位置する天部側二つ折り用罫線１Ａ３１ｃ～１Ａ３４ｃと底部側二つ折り用罫線１Ｂ３１ｃ～１Ｂ３４ｃがいずれも容器外面に対して山折りになるように二つ折りすればよい。この二つ折りによって、天部側シート１Ａの天部側側面１Ａ２１～１Ａ２４のうち、互いに隣接する側面を構成する辺同士が重なり合う。図１の拡大図を参照して天部側つなぎ片１Ａ３３について説明すると、この天部側つなぎ片１Ａ３３を天部側二つ折り用罫線１Ａ３３ｃで二つ折りすることにより、この天部側つなぎ片１Ａ３３の両側に位置する天部側側面１Ａ２３の辺１Ａ２３ｂと天部側側面１Ａ２４の辺１Ａ２４ｂとが互いに重なり合い、また、天部側二つ折り用罫線１Ａ３１ｃ～１Ａ３４ｃのそれぞれによって区分された２つの領域が互いに重なり合って、フィン状パネル１３３の天部側を構成する。図１の拡大図を参照して天部側つなぎ片１Ａ３３について説明すると、この天部側つなぎ片１Ａ３３を天部側二つ折り用罫線１Ａ３３ｃで二つ折りすることにより、この天部側つなぎ片１Ａ３３の両側に位置する天部側側面１Ａ２３の辺１Ａ２３ｂと天部側側面１Ａ２４の辺１Ａ２４ｂとが互いに重なり合う。また、天部側二つ折り用罫線１Ａ３３ｃで区分された２つの領域１Ａ３３１，１Ａ３３２が互いに重なり合って、包装容器の各角部から外側に向けて突出するフィン状パネル１３３の天部側を構成する。なお、このフィン状パネル１３３の天部側において、領域１Ａ３３１及び領域１Ａ３３２の外側の天部側固定部１Ａ４３β，１Ａ４４αの端縁から二つ折り用罫線被覆片１Ａ５４αが突出していることは前述のとおりである。 Next, a method for transforming the flat packaging container 1 into a box shape will be described. For this purpose, the top side connecting pieces 1A31 to 1A34 and the bottom side connecting pieces 1B31 to 1B34 are arranged so that the top side double-folding crease lines 1A31c to 1A34c and the bottom side double-folding crease lines 1B31c to 1B34c located in the center of each It should be folded in two so that it forms a mountain fold with respect to the outer surface of the container. As a result of this folding, the sides forming adjacent side surfaces of the top-side side surfaces 1A21 to 1A24 of the top-side sheet 1A overlap with each other. The top side connecting piece 1A33 will be described with reference to the enlarged view of FIG. The side 1A23b of the top-side side surface 1A23 and the side 1A24b of the top-side side surface 1A24 located on both sides overlap each other, and the two areas divided by the top-side double-folding lines 1A31c to 1A34c overlap each other. and form the top side of the fin-shaped panel 133 . The top side connecting piece 1A33 will be described with reference to the enlarged view of FIG. Side 1A23b of top-side side 1A23 and side 1A24b of top-side side 1A24 located on both sides overlap each other. Two areas 1A331 and 1A332 divided by the top side double-folding ruled line 1A33c overlap each other to form the top side of the fin-shaped panel 133 projecting outward from each corner of the packaging container. As described above, on the top side of the fin-like panel 133, the double-folding ruled line cover pieces 1A54α protrude from the edges of the top side fixing portions 1A43β and 1A44α outside the regions 1A331 and 1A332. be.

ところで、平坦な状態の包装容器１においては、天部側シート１Ａの天部側つなぎ片１Ａ３３と底部側シート１Ｂの底部側つなぎ片１Ｂ３３とは正確に重なり合い、その天部側二つ折り用罫線１Ａ３３ｃと底部側二つ折り用罫線１Ｂ３３ｃも互いに正確に重なり合っており、天部側シート１Ａの天部側つなぎ片１Ａ３３を天部側二つ折り用罫線１Ａ３３ｃで二つ折りするとき、底部側シート１Ｂの底部側つなぎ片１Ｂ３３も底部側二つ折り用罫線１Ｂ３３ｃで二つ折りされる。このため、底部側つなぎ片１Ｂ３３の両側に位置する底部側側面１Ｂ２３の辺１Ｂ２３ｂと底部側側面１Ｂ２４の辺１Ｂ２４ｂも互いに重なり合い、また、底部側二つ折り用罫線１Ｂ３３ｃで区分された２つの領域も互いに重なり合っ
て、包装容器の各角部から外側に向けて突出するフィン状パネル１３３の底部側を構成する。なお、このときにも、二つ折り用罫線被覆片１Ａ５４αが領域１Ａ３３１及び領域１Ａ３３２の外側の天部側固定部１Ａ４３β，１Ａ４４αの端縁から突出している。 By the way, in the packaging container 1 in a flat state, the top-side connecting piece 1A33 of the top-side sheet 1A and the bottom-side connecting piece 1B33 of the bottom-side sheet 1B are precisely overlapped, and the top-side double-folding crease 1A33c is formed. and the bottom-side double-folding ruled line 1B33c are also precisely overlapped with each other. The connecting piece 1B33 is also folded in half along the bottom side folding ruled line 1B33c. Therefore, the side 1B23b of the bottom side surface 1B23 and the side 1B24b of the bottom side surface 1B24 located on both sides of the bottom side connecting piece 1B33 overlap each other, and the two areas separated by the bottom side double-folding ruled line 1B33c also overlap each other. Together they form the bottom side of a finned panel 133 projecting outwardly from each corner of the package. Also at this time, the double-folding ruled line covering piece 1A54α protrudes from the edges of the top fixing portions 1A43β and 1A44α outside the regions 1A331 and 1A332.

そして、天部側シート１Ａの天部側側面１Ａ２３と底部側シート１Ｂの底部側側面１Ｂ２３とは容器固定部１４０を介して連続しているから、この両側面１Ａ２３，１Ｂ２３によって箱型の状態の包装容器１の側面１２３が構成される。 Since the top-side side surface 1A23 of the top-side sheet 1A and the bottom-side side surface 1B23 of the bottom-side sheet 1B are continuous via the container fixing portion 140, the two side surfaces 1A23 and 1B23 form a box shape. A side surface 123 of the packaging container 1 is configured.

また、天部側シート１Ａの天部側つなぎ片１Ａ３３と底部側シート１Ｂの底部側つなぎ片１Ｂ３３も容器固定部１４０を介して連続しているから、この両つなぎ片１Ａ３３，１Ｂ３３で構成された部分をフィン状パネル１３３として、このフィン状パネル１３３によって前記側面同士を繋いでしかも閉塞する。すなわち、天部側側面１Ａ２３と底部側側面１Ｂ２３とで構成される側面１２３と、天部側側面１Ａ２４と底部側側面１Ｂ２４とで構成される側面１２４との間を、フィン状パネル１３３で繋いで、しかも、ここに隙間が生じることがないように閉塞するのである。 In addition, since the top-side joint piece 1A33 of the top-side sheet 1A and the bottom-side joint piece 1B33 of the bottom-side sheet 1B are also continuous via the container fixing portion 140, the two joint pieces 1A33 and 1B33 are formed. A fin-like panel 133 is used to connect and close the side surfaces with the fin-like panel 133 . That is, a fin-like panel 133 connects a side surface 123 composed of a top side surface 1A23 and a bottom side surface 1B23 and a side surface 124 composed of a top side surface 1A24 and a bottom side surface 1B24. Moreover, it is closed so as not to create a gap here.

以上、天部側つなぎ片１Ａ３３及び底部側つなぎ片１Ｂ３３で構成された部分を二つ折りする場合を例として説明したが、被覆片対応天部側つなぎ片を構成している天部側つなぎ片１Ａ３４と底部側つなぎ片１Ｂ３４についても同様である。すなわち、天部側つなぎ片１Ａ３４及び底部側つなぎ片１Ｂ３４で構成された部分を、その中央の天部側二つ折り用罫線１Ａ３４ｃ及び底部側二つ折り用罫線１Ｂ３４ｃがいずれも容器外面に対して山折りになるように二つ折りすることにより、天部側側面１Ａ２４と底部側側面１Ｂ２４とで構成される側面１２４及び天部側側面１Ａ２１と底部側側面１Ｂ２１とで構成される側面１２１が構成され、これら側面１２４と側面１２１との間をフィン状パネル１３４で繋いで閉塞する。また、二つ折り用罫線被覆片１Ａ５４βが領域１Ａ３４１及び領域１Ａ３４２の外側の天部側固定部１Ａ４４β，１Ａ４１αの端縁から突出している。 The case of folding the portion composed of the top-side connecting piece 1A33 and the bottom-side connecting piece 1B33 has been described above as an example, but the top-side connecting piece 1A34 constituting the top-side connecting piece corresponding to the covering piece and the bottom side connecting piece 1B34. That is, the portion composed of the top-side connecting piece 1A34 and the bottom-side connecting piece 1B34 is mountain-folded with respect to the outer surface of the container by the central top-side double-folding ruled line 1A34c and the bottom-side double-folding ruled line 1B34c. By folding in two so as to form a side surface 124 composed of a top side surface 1A24 and a bottom side surface 1B24 and a side surface 121 composed of a top side surface 1A21 and a bottom side surface 1B21, these A fin-like panel 134 connects and closes the side 124 and the side 121 . Further, the double-folding ruled line covering piece 1A54β protrudes from the edges of the top side fixing portions 1A44β and 1A41α outside the regions 1A341 and 1A342.

また、天部側つなぎ片１Ａ３１と底部側つなぎ片１Ｂ３１については、天部側つなぎ片１Ａ３１には二つ折り用罫線被覆片が設けられていないから、この二つ折り用罫線被覆片が突出することはない。その他の点については、天部側つなぎ片１Ａ３３及び底部側つなぎ片１Ｂ３３の場合と同様である。すなわち、天部側つなぎ片１Ａ３１及び底部側つなぎ片１Ｂ３１で構成された部分を、その中央の天部側二つ折り用罫線１Ａ３１ｃ及び底部側二つ折り用罫線１Ｂ３１ｃがいずれも容器外面に対して山折りになるように二つ折りすることにより、天部側側面１Ａ２１と底部側側面１Ｂ２１とで構成される側面１２１及び天部側側面１Ａ２２と底部側側面１Ｂ２２とで構成される側面１２２が構成され、これら側面１２１と側面１２２との間をフィン状パネル１３１で繋いで閉塞する。 As for the top-side connecting piece 1A31 and the bottom-side connecting piece 1B31, since the top-side connecting piece 1A31 is not provided with the double-folding ruled line covering piece, the double-folding ruled line covering piece does not protrude. do not have. Other points are the same as those of the top side connecting piece 1A33 and the bottom side connecting piece 1B33. That is, the portion composed of the top-side connecting piece 1A31 and the bottom-side connecting piece 1B31 is mountain-folded with respect to the outer surface of the container by the central top-side double-folding ruled line 1A31c and the bottom-side double-folding ruled line 1B31c. By folding it in two, a side surface 121 composed of a top side surface 1A21 and a bottom side surface 1B21 and a side surface 122 composed of a top side surface 1A22 and a bottom side surface 1B22 are formed. A fin-shaped panel 131 connects and closes the side 121 and the side 122 .

また、天部側つなぎ片１Ａ３２と底部側つなぎ片１Ｂ３２についても、天部側つなぎ片１Ａ３１と底部側つなぎ片１Ｂ３１と同様である。この天部側つなぎ片１Ａ３２にも二つ折り用罫線被覆片が設けられていないから、この二つ折り用罫線被覆片が突出することはない。すなわち、天部側つなぎ片１Ａ３２及び底部側つなぎ片１Ｂ３２で構成された部分を、その中央の天部側二つ折り用罫線１Ａ３２ｃ及び底部側二つ折り用罫線１Ｂ３２ｃがいずれも容器外面に対して山折りになるように二つ折りすることにより、天部側側面１Ａ２２と底部側側面１Ｂ２２とで構成される側面１２２及び天部側側面１Ａ２３と底部側側面１Ｂ２３とで構成される側面１２３が構成され、これら側面１２２と側面１２３との間をフィン状パネル１３２で繋いで閉塞する。 Also, the top side connecting piece 1A32 and the bottom side connecting piece 1B32 are the same as the top side connecting piece 1A31 and the bottom side connecting piece 1B31. Since the top-side connecting piece 1A32 is also not provided with a double-folding ruled line covering piece, the double-folding ruled line covering piece does not protrude. That is, the portion composed of the top-side connecting piece 1A32 and the bottom-side connecting piece 1B32 is mountain-folded with respect to the outer surface of the container by the central top-side double-folding ruled line 1A32c and the bottom-side double-folding ruled line 1B32c. A side surface 122 composed of a top side surface 1A22 and a bottom side surface 1B22 and a side surface 123 composed of a top side surface 1A23 and a bottom side surface 1B23 are formed by folding in two so that A fin-shaped panel 132 connects and closes the side 122 and the side 123 .

そして、このようにすべての天部側つなぎ片１Ａ３１～１Ａ３４と底部側つなぎ片１Ｂ３１～１Ｂ４を二つ折りすることにより、各側面１２１～１２４が形成されるから、これに伴って所定の折り曲げ用罫線で折り曲げられ、包装容器１を箱型の状態に変形すること
ができる。この箱型の状態の包装容器１は、天面１Ａ１０と底面１Ｂ１０とを有し、その周囲に側面１２１～１２４が設けられており、しかも、側面１２１～１２４の間をフィン状パネル１３１～１３４が閉塞しているから、前記開口部１Ａ１１を除いて密封された状態にある。 By folding all the top side connecting pieces 1A31 to 1A34 and the bottom side connecting pieces 1B31 to 1B4 in half in this way, the side surfaces 121 to 124 are formed. , and the packaging container 1 can be transformed into a box shape. The box-shaped packaging container 1 has a top surface 1A10 and a bottom surface 1B10, and side surfaces 121 to 124 are provided around the top surface 1A10. is closed, it is in a sealed state except for the opening 1A11.

なお、底部側シート１Ｂの底部側固定部１Ｂ４０の前記境界には折り曲げ用罫線が設けられており、天部側シート１Ａの天部側固定部１Ａ４０の前記境界には折り曲げ用罫線が設けられていないから、両固定部１Ａ４０，１Ｂ４０がヒートシールされて形成された容器固定部１４０は、底部側シート１Ｂの方向に折り曲げられる。すなわち、底部側固定部１Ｂ４０は前記境界に設けられた折り曲げ用罫線で底部側シート１Ｂの方向に折り曲げられ、天部側シート１Ａの天部側固定部１Ａ４０は、その境界で折り曲げられることなく、底部側シート１Ｂの底部側固定部１Ｂ４０の外面側に重ねられる。このとき、天部側側面１Ａ２４の位置において前記天部側固定部１Ａ４４の外側には固定部端面被覆片１Ａ５４が設けられているから、この固定部端面被覆片１Ａ５４が底部側固定部１Ｂ４４の端面を被覆する。そして、この固定部端面被覆片１Ａ５４を底部側側面１Ｂ２４に接着することにより、これら天部側固定部１Ａ４４と底部側固定部１Ｂ４４とで構成される固定部１４４が容器側面１Ａ２４，１Ｂ２４から浮き上がることを防ぐことができる。 A folding ruled line is provided at the boundary of the bottom side fixed portion 1B40 of the bottom side sheet 1B, and a folding ruled line is provided at the boundary of the top side fixed portion 1A40 of the top side sheet 1A. Therefore, the container fixing portion 140 formed by heat-sealing both the fixing portions 1A40 and 1B40 is folded toward the bottom side sheet 1B. That is, the bottom-side fixed portion 1B40 is folded toward the bottom-side sheet 1B along the folding ruled line provided at the boundary, and the top-side fixed portion 1A40 of the top-side sheet 1A is not folded at the boundary. It is overlaid on the outer surface side of the bottom side fixing portion 1B40 of the bottom side sheet 1B. At this time, since the fixing portion end surface covering piece 1A54 is provided outside the top fixing portion 1A44 at the position of the top side surface 1A24, the fixing portion end surface covering piece 1A54 is the end surface of the bottom fixing portion 1B44. to cover. By bonding the fixing portion end surface covering piece 1A54 to the bottom side surface 1B24, the fixing portion 144 composed of the top side fixing portion 1A44 and the bottom side fixing portion 1B44 is lifted from the container side surfaces 1A24 and 1B24. can be prevented.

ところで、このように箱型の状態に変形された状態では、二つ折りされたフィン状パネル１３１～１３４が包装容器１の外面に突出している。そこで、その外観を整えるため、このフィン状パネル１３１～１３４を倒して包装容器の側面に重ね合わせることが必要である。 By the way, the fin-shaped panels 131 to 134 folded in two protrude from the outer surface of the packaging container 1 in the box-shaped state. Therefore, in order to arrange the appearance, it is necessary to fold the fin-like panels 131 to 134 over the sides of the packaging container.

ところで、フィン状パネル１３３，１３４を倒す際には、二つ折り用罫線被覆片１Ａ５４α，１Ａ５４βによって底部側二つ折り用罫線を被覆するように倒し、この二つ折り用罫線被覆片１Ａ５４α，１Ａ５４βを包装容器の側面に接着することによって、フィン状パネルが包装容器の側面から浮き上がることを防止することができる。 By the way, when the fin-shaped panels 133 and 134 are laid down, they are laid down so that the half-folding ruled lines on the bottom side are covered with the two-folding ruled line covering pieces 1A54α and 1A54β, and the two-folding ruled line covering pieces 1A54α and 1A54β are placed on the packaging container. By adhering to the side surface of the packaging container, the fin-like panel can be prevented from rising from the side surface of the packaging container.

すなわち、図４に示すように、天部側つなぎ片１Ａ３３及び底部側つなぎ片１Ｂ３３で構成された部分を二つ折りして構成されたフィン状パネル１３３を倒して、天部側側面１Ａ２３及び底部側側面１Ｂ２３に重ねることにより、天部側つなぎ片１Ａ３３を構成する二つの前記領域１Ａ３３１，１Ａ３３２のうち、天部側側面１Ａ２３に隣接する領域１Ａ３３１が天部側側面１Ａ２３の外面側に重なり、かつ、天部側側面１Ａ２４に隣接する領域１Ａ３３２が前記領域１Ａ３３１の外面側に重なるようにフィン状パネル１３３を倒すことにより、領域１Ａ３３２に対応する位置の天部側固定部１Ａ４４αの外側に配置された二つ折り用罫線被覆片１Ａ５４αによって底部側二つ折り用罫線１Ｂ３３ｃを被覆することができる。そして、二つ折り用罫線被覆片１Ａ５４αは底部側二つ折り用罫線１Ｂ３３ｃから突出しているから、これを天部側側面１Ａ２３や底部側側面１Ｂ２３に接着することによって、前記フィン状パネル１３３が包装容器の側面から浮き上がることを防止することが可能である。 That is, as shown in FIG. 4, the fin-shaped panel 133 constructed by folding the portion composed of the top-side connecting piece 1A33 and the bottom-side connecting piece 1B33 is folded down, and the top-side side surface 1A23 and the bottom-side surface 1A23 are folded down. By overlapping with the side surface 1B23, of the two regions 1A331 and 1A332 constituting the top side connecting piece 1A33, the region 1A331 adjacent to the top side side surface 1A23 overlaps with the outer surface side of the top side surface 1A23, and By laying down the fin-shaped panel 133 so that the region 1A332 adjacent to the top side side surface 1A24 overlaps the outer surface side of the region 1A331, the two parts arranged outside the top side fixing portion 1A44α at the position corresponding to the region 1A332 The bottom side double-folding ruled line 1B33c can be covered with the folding ruled-line covering piece 1A54α. Since the double-folding ruled line covering piece 1A54α protrudes from the bottom-side double-folding ruled line 1B33c, the fin-shaped panel 133 is formed into the packaging container by adhering it to the top side surface 1A23 and the bottom side surface 1B23. It is possible to prevent floating from the side surface.

なお、天部側つなぎ片１Ａ３４及び底部側つなぎ片１Ｂ３４で構成された部分についても同様である。 The same applies to the portion formed by the top side connecting piece 1A34 and the bottom side connecting piece 1B34.

なお、このように箱型の状態に変形することにより、包装体の内容積が増大するから、前記口栓１Ｃを通じて熱湯、温水又は冷水を注ぎ入れることができる。また、前述のようにこの箱型の状態の包装体は口栓１Ｃの開口部を除いて密閉されているから、その熱湯等が漏れることもない。そして、この包装体を十分に振ることによって、内容物を熱湯等に溶解することが可能である。 In addition, since the inner volume of the package is increased by transforming it into a box shape, hot water, hot water or cold water can be poured through the plug 1C. Further, as described above, the box-shaped packaging body is sealed except for the opening of the plug 1C, so that hot water or the like does not leak. By sufficiently shaking the package, the contents can be dissolved in hot water or the like.

次に、この包装容器１を廃棄する際には、空になった包装体を平坦な状態に変形させて廃棄することが望ましい。箱型の状態の包装容器１を平坦な状態に変形させるためには、まず、底部側側面１Ｂ２４に接着した固定部端面被覆片１Ａ５４を引き剥がすと共に、各フィン状パネルを包装容器の側面から引き剥がし、次に、容器固定部１４０を把持して、包装容器１の外方に引っ張ればよい。容器固定部１４０を外方に引っ張ることにより、二つ折りされたつなぎ片１３１～１３４が開き、包装容器１を平坦な状態に変形する。 Next, when discarding the packaging container 1, it is desirable to deform the empty package into a flat state before discarding. In order to transform the box-shaped packaging container 1 into a flat state, first, the fixing portion end surface covering piece 1A54 adhered to the bottom side surface 1B24 is peeled off, and each fin-like panel is pulled from the side surface of the packaging container. After peeling off, the container fixing portion 140 may be grasped and pulled to the outside of the packaging container 1 . By pulling the container fixing portion 140 outward, the two-fold connecting pieces 131 to 134 are opened, and the packaging container 1 is deformed into a flat state.

なお、天部側シート１Ａや底部側シート１Ｂとしては、例えば、紙製の基材層に、熱可塑性樹脂層やシーラント層を積層した積層フィルムを好適に用いることができる。これ以外にも、必要な機能に応じて、バリア層や機能性フィルム等を適宜追加してもよい。また、天部側シート１Ａや底部側シート１Ｂの端部は、既知の方法で端面保護されていてもよい。 As the top-side sheet 1A and the bottom-side sheet 1B, for example, a laminated film obtained by laminating a thermoplastic resin layer or a sealant layer on a paper base layer can be preferably used. In addition to these, a barrier layer, a functional film, or the like may be added as appropriate depending on the required functions. Also, the ends of the top-side sheet 1A and the bottom-side sheet 1B may be end-face protected by a known method.

（第１の具体例の第１の変形例）
この例は、図５及び図６に示すように、天部側シートとして、その開口部１Ａ１１に口栓１Ｃを装着した天部側シート１Ａ－２を使用した例で、その他は第１の具体例と同様である。口栓１Ｃには図示しないキャップを装着することができる。 (First Modification of First Specific Example)
As shown in FIGS. 5 and 6, this example uses a top-side sheet 1A-2 having a plug 1C attached to its opening 1A11 as the top-side sheet. Same as example. A cap (not shown) can be attached to the plug 1C.

（第１の具体例の第２の変形例）
この例は、図７に示すように、複数の被覆片対応天部側側面を有する天部側シート１Ａ－３を使用した例である。この例では、二つの被覆片対応天部側側面が包装容器の周方向に１つ置きに配置されている。すなわち、四つの天部側側面１Ａ２１～１Ａ２４に周方向に順番をつけて呼ぶとき、その偶数番目の天部側側面（２番目の天部側側面１Ａ２２及び４番目の天部側側面１Ａ２４）が被覆片対応天部側側面を構成している。 (Second Modification of First Specific Example)
In this example, as shown in FIG. 7, a top-side sheet 1A-3 having top-side side surfaces corresponding to a plurality of covering pieces is used. In this example, the top side surfaces corresponding to the two covering pieces are arranged alternately in the circumferential direction of the packaging container. That is, when the four top side surfaces 1A21 to 1A24 are called in order in the circumferential direction, the even-numbered top side surfaces (the second top side surface 1A22 and the fourth top side surface 1A24) are It constitutes a side surface on the top side corresponding to the covering piece.

例えば２番目の天部側側面１Ａ２２の両側に位置する天部側つなぎ片１Ａ３１及び１Ａ３２の位置において、これに対応する天部側固定部の外側に前記二つ折り用罫線被覆片１Ａ５２α及び１Ａ５２βが設けられている。もちろん、天部側つなぎ片１Ａ３1を天部側二つ折り用罫線１Ａ３1ｃで区分して設けられた二つの領域１Ａ３１１，１Ａ３１２のうち、前記二つ折り用罫線被覆片１Ａ５２αが設けられているのは、天部側側面１Ａ２２に隣接する領域１Ａ３１２に対応する天部側固定部１Ａ４２αの外側である。また、天部側つなぎ片１Ａ３２を天部側二つ折り用罫線１Ａ３２ｃで区分して設けられた二つの領域１Ａ３２１，１Ａ３２２のうち、前記二つ折り用罫線被覆片１Ａ５２βが設けられているのは、天部側側面１Ａ２２に隣接する領域１Ａ３２１に対応する天部側固定部１Ａ４２βの外側である。 For example, at the positions of the top-side connecting pieces 1A31 and 1A32 located on both sides of the second top-side side surface 1A22, the double-folding ruled line cover pieces 1A52α and 1A52β are provided outside the corresponding top-side fixing portion. It is Of course, of the two areas 1A311 and 1A312 provided by dividing the top side connecting piece 1A31 by the top side double-folding ruled line 1A31c, the double-folding ruled line covering piece 1A52α is provided in the top side.
