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。 Further, in the bottom sheet 1B', each side of the polygonal bottom surface 1B'10 is used as a fold ruled line, and the rectangular bottom side side surface 1B'21 to 1B'24 having each side as one side is formed into the rectangular shape. It has four, which is the same as the number of sides of the bottom surface 1B'10. These bottom side surfaces 1B'21 to 1B'24 are also 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。 Further, the bottom sheet 1B'is a bottom side connecting piece 1B that connects and closes the bottom side side surfaces 1B'21 to 1B'24 between the bottom side side surfaces 1B'21 to 1B'24 adjacent to each other. It has '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。 Further, a bending ruled line is provided between each bottom side side surface 1B'21 to 1B'24 and the bottom side connecting piece 1B'31 to 1B'34. Further, in each bottom side connecting piece 1B'31 to 1B'34, the bottom side folding rule line 1B'31c to divide the bottom side connecting piece 1B'31 to 1B'34 into two equal parts from each apex 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 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 placed on the outside of the rectangular portion in which the bottom side side surfaces 1B'21 to 1B'24 and the bottom side connecting piece 1B'31 to 1B'34 are combined, and the top side sheet 1A' It has a bottom-side fixing portion 1B'40 composed of a heat-sealing region 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 both fixing portions 1A'40 and 1B'40 are heat-sealed to form a flat packaging container 1'. Can be manufactured. The packaging container 1'can be stored in such a flat state and can be supplied to the step 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-shaped state, each of the top side sheet 1A'and the bottom side sheet 1B' may be bent by the bending ruled line and started up.

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'formed in this way, the top side connecting piece 1A'31 to 1A'34 and the bottom side connecting piece 1B'31 to 1B'34 are located at the center of the top side two. Both the folding rule lines 1A'31c to 1A'34c and the bottom side folding rule 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. By this folding, the sides forming the side surfaces adjacent to each other among the top side sides 1A'21 to 1A'24 of the top side sheet 1A'overlap each other, and the top side folding ruled line 1A'31c The two regions separated by each of ~ 1A'34c overlap each other to form the top side of the fin-shaped panel. The top side connecting piece 1A'33 will be described with reference to the enlarged view of FIG. 11. By folding the top side connecting piece 1A'33 in half along the top side folding rule line 1A'33c, this heaven The side 1A'23b of the top side surface 1A'23 located on both sides of the side connecting piece 1A'33 and the side 1A'24b of the top side side surface 1A'24 overlap each other. Further, the top portion of the fin-shaped panel in which the two regions 1A'331 and 1A'332 divided by the ruled line 1A'33c for folding in half on the top side overlap each other and project outward from each corner of the packaging container. Make up the 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 flat packaging container 1', 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' accurately overlap each other, and the top side connecting piece 1B'33 The side fold ruled line 1A'33c and the bottom side fold ruled line 1B'33c also overlap each other accurately, and the top side connecting piece 1A'33 of the top side sheet 1A'is overlapped with the top side fold ruled line. When 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 folding ruled line 1B'33c. Therefore, the side 1B'23b of the bottom side side surface 1B'23 and the side 1B'24b of the bottom side side surface 1B24 located on both sides of the bottom side connecting piece 1B'33 also overlap each other, and the bottom side folding ruled line 1B' The two regions separated by 33c also overlap each other to form a fin-shaped panel 133'protruding outward from each corner of the packaging container.

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 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', both side surfaces 1A' 23, 1B'23 constitutes the side surface 123'of the box-shaped packaging container 1.

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。 Further, 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', these two connecting pieces are also connected. The side surfaces are connected to each other and closed by a portion composed of 1A'33 and 1B'33. That is, the side surface 123'composed of the top side side surface 1A'23 and the bottom side side surface 1B'23, and the side surface 124'composed of the top side side surface 1A'24 and the bottom side side surface 1B'24. It connects the spaces and closes them so that no gaps are created 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。 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 above 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。 Then, by folding all the connecting pieces 1A'31 to 1A'34 and 1B'31 to 1B'34 in half in this way, each side surface 121'to 124'is formed. It is folded along the folding ruled line, and the packaging container 1'takes a box shape. The 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 side surfaces 121'to 124'. Since the connecting pieces 1A'31 to 1A'34 and 1B'31 to 1B'34 are closed, 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 the box shape in this way, the two-folded connecting pieces 1A'31 to 1A'34 and 1B'31 to 1B'34 form the fin-shaped panels 131'to 134'. The fin-shaped panel protrudes outward from each corner of the packaging container 1'. Therefore, the appearance of the fin-shaped panels 131'to 134' can be adjusted by folding them down and folding them on the side surfaces 121'to 124' of the packaging container 1', for example, heat-sealing and adhering them.

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, in the fin-shaped panel 133', for example, the top side connecting piece 1A'33 is folded in half along the top side folding ruled line 1A'33c, and the two regions 1A'331 and 1A'332 are overlapped with each other. , The bottom side connecting piece 1B'33 is folded in half along the bottom side fold ruled line 1B'33c, and the two areas 1B'331 and 1B'332 are overlapped with each other. The two areas 1A'331 and 1A'332 separated by the ruled line 1A'33c are not bonded to each other, and the two areas 1B'331 and 1B separated by the bottom side folding ruled line 1B'33c. '332 is also not glued to each other.

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 be generated between the region 1A'331 and the region 1A'332, and a gap is likely to be generated between the region 1B'331 and the region 1B'332. Therefore, even when the fin-shaped panel 133'is folded down and folded over and heat-sealed on the side surface of the packaging container 1', the one of the area 1A'331 and the area 1A'332 that does not adhere to the side surface. The area of was raised from the side surface 124'. For example, when the fin-shaped panel 133'composed of the area 1A'331 and the area 1A'332 is tilted and heat-sealed to the side surface 124', the area 1A'332 adheres to the side surface 124'. The region 1A'331 superposed on the region 1A'332 has a gap between the region 1A'331 and the region 1A'332, and the fin-shaped panel 133'is lifted 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。 Therefore, an object of the present invention is to provide a packaging container in which fin-shaped panels projecting outward from each corner of the packaging container do not rise from each side surface 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 the first specific example of the packaging container of the present invention, and FIGS. 1 and 2 show the top side sheet 1A and the bottom side sheet 1B of the packaging container, respectively.

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 thereof, similarly to the conventional top side sheet 1A'. In this example, it is rectangular. An opening 1A11 is provided on 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 a quadrangular top side side surface 1A21 to 1A24 having each side of the polygonal top surface 1A10 as a bending ruled line and each side of the top surface 1A10 as one side. 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 has a quadrangular shape, the number of sides of the quadrangular top surface 1A10 is 4, and the number of the top side surfaces 1A21 to 1A24 is also 4.

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 a top side connecting piece 1A31 to 1A34 connecting the top side sides 1A21 to 1A24 between the top side surfaces adjacent to each other. That is, the top side side surface 1A21 and the top side side surface 1A22 are connected by a top side connecting piece 1A31. Further, 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. A fold ruled line is provided between the top side side surfaces 1A21 to 1A24 and the top side connecting piece 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。 Then, the space between the top side surfaces 1A21 to 1A24 is closed by the top side connecting pieces 1A31 to 1A34. As shown in the figure, in this example, the outer shape of the portion where the top side side surfaces 1A21 to 1A24 and the top side connecting pieces 1A31 to 1A34 are combined forms a rectangular shape, and each top side connecting piece 1A31 to 1A34 has a rectangular shape. It is located at the corner and closes between the side surfaces 1A21 to 1A24 on the top side. For example, the top side side surface 1A21 and the top side side surface 1A22 are closed 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 a top side folding ruled line that bisects the top side connecting pieces 1A31 to 1A34 from each apex of the top surface 1A10. That is, as shown in an enlarged manner in FIG. 1, for example, the top side surface 1A23 and the top side side surface 1A24 share the apex 1A10b of the top surface 1A10. Among the sides constituting the top side side surface 1A23, the sides sharing the apex 1A10b of the top surface 1A10 are indicated by reference numerals 1A23b. Further, among the sides constituting the top side side surface 1A24, the sides sharing the apex 1A10b of the top surface 1A10 are indicated by reference numerals 1A24b. Then, a top side bi-fold ruled line 1A33c that divides the angle formed by the side 1A23b and the side 1A24b into two equal parts is provided, and the top side bi-fold ruled line 1A33c allows the top side connecting piece 1A33 to have two regions 1A331. , 1A332. That is, in the figure, the angle θ1 formed by the side 1A23b and the double-folding ruled line 1A33c is equal to the angle θ2 formed by the side 1A24b and the top-side folding ruled line 1A33c, and the area 1A331 and the area 1A332 have the same shape. It is the same size and is arranged line-symmetrically with the top-side 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 folding ruled line 1A33c has been described above by taking the top side connecting piece 1A33 as an example, but the other top side connecting pieces 1A31 to 1A32 and 1A34 also have the same top side folding ruled line 1A31c to 1A32c. 1A34c is provided, and each is divided into two regions. That is, the top side connecting piece 1A31 is divided into a region 1A311 and a region 1A312 which are arranged in the same shape and in line symmetry by the top side folding ruled line 1A31c. Further, the top side connecting piece 1A32 is divided into a region 1A321 and a region 1A322 which are arranged in the same shape and in line symmetry by the top side folding ruled line 1A32c. Further, the top side connecting piece 1A34 is divided into a region 1A341 and a region 1A342 arranged in the same shape and in line symmetry by the top side folding ruled line 1A34c. In addition, in order to avoid complication, the illustration of these reference numerals 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 a top side fixing portion fixed to the bottom side sheet 1B on the outside of a rectangular portion in which the top side side surfaces 1A21 to 1A24 and the top side connecting pieces 1A31 to 1A34 are combined. It has 1A40. In this example, the top side fixing portion 1A40 is composed of a heat seal region over the entire circumference, but as in the third modification described later, both the top side sheet 1A and the bottom side sheet 1B are 1 In the case of being composed of one sheet, it is also possible to form a part of the top side fixing portion 1A40 with a bending ruled line 1AB for partitioning 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 of the portion corresponding to the top side side surface 1A21, that is, the top side fixing portion located outside the top side side surface 1A21. The part is illustrated with a reference numeral of "1A41". Similarly, the top-side fixing portion of the portion corresponding to the top-side side surface 1A22 is designated by "1A42", and the top-side fixing portion of the portion corresponding to the top-side side surface 1A23 is designated by "1A43". A reference numeral is attached, and a reference numeral of "1A44" is attached to the top portion side fixing portion of the portion corresponding to the top portion side 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。 Further, the top side connecting pieces 1A31 and 1A34 are arranged on both sides of the top side side surface 1A21, and the top side connecting pieces 1A34 are separated by the top side 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 located outside the region 1A342 is designated by "1A41α". Is attached to the figure. Further, of the two regions 1A311, 1A312 provided by dividing the top side connecting piece 1A31 by the top side 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 located 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 boundary between the top side fixing portion 1A40 and the top side side surfaces 1A21 to 1A24 and the boundary between the top side fixing portion 1A40 and the top side connecting piece 1A31 to 1A34 are shown by broken lines. However, these are provided for convenience of explanation. Unlike the boundary between the bottom side fixing portion 1B40 and the bottom side side surfaces 1B21 to 1B24 of the bottom side sheet 1B described later, there is no bending ruled line at the boundary between the top side fixing portion 1A40 and the top side side surface 1A21 to 1A24. .. There is no bending ruled line at the boundary between the top-side fixing portion 1A40 and the top-side connecting piece 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 on the outside of the top side fixing portion, and moreover, two regions constituting the top side connecting piece 1A33. The double-folded ruled line covering piece 1A54α is selectively provided on the outside of the top-side fixing portion 1A44α at a position corresponding to one region 1A332 of 1A331 and 1A332, and the ceiling at a position corresponding to the other region 1A331. A ruled line covering piece for folding in half is not provided on the outside of the portion-side fixing portion 1A43β. Therefore, when the top side connecting piece 1A33 is folded in half at the top side folding ruled line 1A33c and the areas 1A331 and 1A332 are overlapped with each other to form the top side of the fin-shaped panel, the folding ruled line coating is formed. The piece 1A54α projects from the edge of the region 1A331. Then, of the two regions 1A331 and 1A332, the region 1A331 is in close contact with the side surface 1A23 of the packaging container 1, and the fin-shaped panel is tilted down so that the region 1A332 is located on the outer surface side thereof and overlapped with the side surface 1A23. The folding ruled line coating piece 1A54α can cover the end face of the fin-shaped panel to prevent the end face from being exposed to the outer surface of the packaging container 1. Therefore, by adhering the ruled line coating piece 1A54α for folding in half to the side surface 1A23, the fin-shaped panel is prevented from rising from the side surface 1A23 of the packaging container 1.

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。 It is not necessary to completely prevent the gap between the fin-shaped panel and the side surface 1A23 by adhering the two-fold ruled line coating piece 1A54α 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 bi-fold ruled line covering piece is provided is called the covering piece corresponding top side connecting piece, in this first specific example, the top side side surface 1A24 The top-side connecting pieces 1A33 and 1A34 on both sides of the above form the top-side connecting piece corresponding to the covering piece. That is, as described above, first, of the two regions 1A331 and 1A332 constituting the top side connecting piece 1A33, the fold line covering is selectively performed at a position corresponding to the region 1A332 adjacent to the top side side surface 1A24. The piece 1A54α is provided, and the ruled line covering piece for folding in half is not provided at the position corresponding to the other area 1A331. Further, the ruled line covering piece 1A54β for folding in half is selectively provided at a position corresponding to the region 1A341 adjacent to the side surface 1A24 on the top side of the two regions 1A341 and 1A342 constituting the connecting piece 1A34 on the top side. , The ruled line covering piece for folding in half is not provided at the position corresponding to the other region 1A342.

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, the fixing portion end face covering piece 1A54 is provided on the outside of the top side fixing portion 1A44 at the position of the top side side surface 1A24. As will be described later, the fixed portion end face covering piece 1A54 is an end face of a fixed portion formed by overlapping the top side fixing portion 1A44 and the bottom side fixing portion 1B44 when the packaging container 1 is in a box shape. This is intended to prevent the end face 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。 It is not necessary that the end face covering piece 1A54 of the fixed portion and the ruled line covering pieces 1A54α and 1A54β for folding in half are connected to each other, but it is desirable that they are connected to each other via the ruled line for bending. In this example, as shown in the figure, the fixed portion end face covering piece 1A54 and the double-folding ruled line covering piece 1A54α are connected to each other via a folding ruled line, and the fixed portion end face covering piece 1A54 and the double-folding ruled line. The coating piece 1A54β is also articulated with 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 heaven side side surface in which the heaven side connecting pieces on both sides constitute the covering piece corresponding heaven side connecting piece is referred to as the covering piece corresponding heaven side side surface, in this first specific example, the covering piece There is only one corresponding top side surface, and the top side side surface 1A24 corresponds to this covering piece corresponding top side side surface, but in the second modification and the third modification of the first specific example described later. As shown, it may have a plurality of covering piece corresponding top side surfaces. In the case of having a plurality of covering piece-corresponding top-side side surfaces in this way, of course, the top-side connecting pieces on both sides of each covering piece-corresponding top-side side surface correspond to a covering piece having a ruled line covering piece for folding in half. Consists of a connecting piece on the top side. When every other top-side side surface corresponding to the covering piece is arranged in the circumferential direction of the packaging container, all the top-side connecting pieces form the covering piece-corresponding top-side connecting piece.

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 overlapped with each other. In order to accurately align both sheets 1A and 1B, it is desirable that two or more of the chips 1A4x are provided. In this example, it is provided at four locations (top fixed portion 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 the same as the conventional bottom sheet 1B'. In this first specific example, it is the same as the conventional bottom sheet 1B'except that it has a notch 1B4x for alignment, and has the same structure as the top side sheet 1A except for three points described later. have. That is, 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 point that the bottom sheet 1B is different from the top sheet 1A is that the top surface 1A10 of the top sheet 1A is provided with an opening, whereas the bottom surface 1B10 of the bottom 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。 Further, in the bottom sheet 1B, each side of the polygonal bottom surface 1B10 is used as a fold ruled line, and the square bottom side side surfaces 1B21 to 1B24 having each side as one side are used as the number of sides of the polygonal bottom surface 1B10. I have the same number. These bottom 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 a bottom side connecting piece 1B31 to 1B34 that connects and closes the bottom side side surfaces 1B21 to 1B24 between the bottom side side surfaces 1B21 to 1B24 adjacent to each other. 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。 Further, a bending ruled line is provided between each bottom side side surface 1B21 to 1B24 and the bottom side connecting piece 1B31 to 1B34. Further, each bottom side connecting piece 1B31 to 1B34 is provided with a bottom side bi-folding ruled line 1B31c to 1B34c that bisects the bottom side connecting piece 1B31 to 1B34 from each apex of the bottom surface 1B10. The bottom side connecting pieces 1B31 to 1B34 are each divided into two regions by the two-fold 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 fixed to the top side sheet 1A on the outside of a rectangular portion in which the bottom side side surfaces 1B21 to 1B24 and the bottom side connecting pieces 1B31 to 1B34 are combined. doing. In this example, the bottom side fixing portion 1B40 is a heat seal region 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 at the boundary between the bottom side fixing portion 1B40 and the bottom side side surfaces 1B21 to 1B24 of the bottom side sheet 1B, and the boundary between the bottom side fixing portion 1B40 and the bottom side connecting piece 1B31 to 1B34. .. Since there is no bending 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. Since the bottom side sheet 1B is provided with a ruled line for bending and does not exist on the top side sheet 1A in this way, when both sheets 1A and 1B are overlapped and fixed to form a box shape. Both the fixing portions 1A40 and 1B40 fixed to each other are bent toward the bottom side sheet 1B side by the bending ruled line 1Bx, and the top side sheet 1A is overlapped on the outer side thereof. As described above, since the fixing portion end face covering piece 1A54 is provided on the outside of the top side fixing portion 1A44 at the position of the top side side surface 1A24, the top side fixing portion 1A44 and the bottom side fixing portion are provided. It is possible to cover the end face of the fixed portion formed by overlapping 1B44 and 1B44 to prevent the end face 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。 The bottom side fixing portion 1B40 is also provided with a notch 1B4x for alignment. The 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 sheet 1B are overlapped. desirable. In this example, since the number of the alignment notches 1A4x of the top side fixing portion 1A40 is four (top side fixing portions 1A41α, 1A41β, 1A43α, 1A43β), the alignment notches 1B4x of the bottom side fixing portion 1B40 There are also four locations (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, a method of manufacturing the packaging container 1 in a flat state will be described with reference to FIG. That is, the packaging container 1 in a flat state can be manufactured by aligning the top side sheet 1A and the bottom side sheet 1B and stacking them, and heat-sealing both 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-side fixing portion 1A44 located outside the top-side side surface 1A24 and the bottom-side fixing portion 1B44 located outside the bottom-side side surface 1B24 are heat-sealed with each other. , The fixing portion end face covering piece 1A54 located outside the top side fixing portion 1A44 projects from the edge 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. 3B, of the two regions 1A331 and 1A332 constituting the top side connecting piece 1A33, the top side fixed 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 with each other, and the two-fold 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. It protrudes from the edge of the portion 1B44α. On the other hand, although not shown, a ruled line covering piece for folding in half is provided on the outside of the area 1A331 which is not adjacent to the side surface 1A24 on the top side of the two areas 1A331 and 1A332 constituting the connecting piece 1A33 on the top side. Of course, it does not protrude from the edge 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 by the double fold ruled line 1A33c, the region 1A331 and the region 1A332 are overlapped with each other, and the double fold ruled line covering piece 1A54α protruding from the region 1A332 is formed in the region 1A331 and the region 1A332. It protrudes from the edge 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 by the ruled line 1B33c for folding in half, the area 1B331 and the area 1B332 are overlapped with each other. By folding the top side connecting piece 1A33 and the bottom side connecting piece 1B33 in half with the two-fold ruled lines 1A33c and 1B33c in this way, the portion where the area 1A331 and the area 1A332 are overlapped with each other and the area 1B331 and the area 1B332 become The fin-shaped panel 133 can be formed by the portions that are overlapped with each other. Since the double-folded ruled line covering piece 1A54α protrudes from the top side of the fin-shaped panel 133, the double-folded ruled line covering piece 1A54α is tilted so as to be on the outer surface side of the packaging container 1. The two-fold ruled line 1B33c can be covered with the two-fold ruled line coating 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 of transforming the flat packaging container 1 into a box-shaped state will be described. For this purpose, the top side connecting pieces 1A31 to 1A34 and the bottom side connecting pieces 1B31 to 1B34 are either the top side folding ruled lines 1A31c to 1A34c and the bottom side folding ruled lines 1B31c to 1B34c located at the center thereof. It can be folded in half so that it folds in half with respect to the outer surface of the container. By this folding, the sides of the top side surfaces 1A21 to 1A24 of the top side sheet 1A that form the side surfaces adjacent to each other overlap each other. The top side connecting piece 1A33 will be described with reference to the enlarged view of FIG. 1. By folding the top side connecting piece 1A33 in half along the top side folding rule line 1A33c, the top side connecting piece 1A33 The side 1A23b of the top side surface 1A23 located on both sides and the side 1A24b of the top side side surface 1A24 overlap each other, and the two regions separated by the top side folding rule lines 1A31c to 1A34c overlap each other. The top side of the fin-shaped panel 133 is formed. The top side connecting piece 1A33 will be described with reference to the enlarged view of FIG. 1. By folding the top side connecting piece 1A33 in half along the top side folding rule line 1A33c, the top side connecting piece 1A33 The side 1A23b of the top side surface 1A23 located on both sides and the side 1A24b of the top side side surface 1A24 overlap each other. Further, the two regions 1A331 and 1A332 divided by the top side folding ruled line 1A33c overlap each other to form the top side of the fin-shaped panel 133 protruding outward from each corner of the packaging container. As described above, on the top side of the fin-shaped panel 133, the ruled line covering piece 1A54α for folding in half protrudes from the edge of the top side fixing portions 1A43β and 1A44α on the outer side of the area 1A331 and the area 1A332. is there.

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 flat packaging container 1, 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 accurately overlap each other, and the top side folding ruled line 1A33c And the bottom side fold ruled line 1B33c also overlap each other accurately, and when the top side connecting piece 1A33 of the top side sheet 1A is folded in half with the top side fold ruled line 1A33c, the bottom side of the bottom side sheet 1B 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 side surface 1B23 and the side 1B24b of the bottom side side surface 1B24 located on both sides of the bottom side connecting piece 1B33 also overlap each other, and the two regions separated by the bottom side double fold ruled line 1B33c also overlap each other. Overlapping, they form the bottom side of the fin-shaped panel 133 that projects outward from each corner of the packaging container. Also at this time, the ruled line covering piece 1A54α for folding in half protrudes from the edge of the outer top side fixing portions 1A43β and 1A44α of the region 1A331 and the region 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 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 side surfaces 1A23 and 1B23 in a box shape are formed. The 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。 Further, since 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 also continuous via the container fixing portion 140, they are composed of both connecting pieces 1A33 and 1B33. The portion is designated as a fin-shaped panel 133, and the side surfaces are connected to each other by the fin-shaped panel 133 and are closed. That is, the side surface 123 composed of the top side side surface 1A23 and the bottom side side surface 1B23 and the side surface 124 composed of the top side side surface 1A24 and the bottom side side surface 1B24 are connected by a fin-shaped panel 133. Moreover, it is closed so that no gap is formed 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 where the portion composed of the top side connecting piece 1A33 and the bottom side connecting piece 1B33 is folded in half has been described above as an example, but the top side connecting piece 1A34 constituting the covering piece corresponding top side connecting piece has been described. The same applies to 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 folded in a mountain with respect to the outer surface of the container by both the top side folding ruled line 1A34c and the bottom side folding ruled line 1B34c. By folding in half so as to be, the side surface 124 composed of the top side side surface 1A24 and the bottom side side surface 1B24 and the side surface 121 composed of the top side side surface 1A21 and the bottom side side surface 1B21 are configured. The side surface 124 and the side surface 121 are connected by a fin-shaped panel 134 to close the surface. Further, the ruled line covering piece 1A54β for folding in half protrudes from the edge of the top-side fixing portions 1A44β and 1A41α on the outer side of the region 1A341 and the region 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。 Further, regarding 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 may protrude. Absent. Other points are the same as in the case 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 folded in a mountain with respect to the outer surface of the container by both the top side folding ruled line 1A31c and the bottom side folding ruled line 1B31c. By folding in half so as to be, the side surface 121 composed of the top side side surface 1A21 and the bottom side side surface 1B21 and the side surface 122 composed of the top side side surface 1A22 and the bottom side side surface 1B22 are configured. The side surface 121 and the side surface 122 are connected by a fin-shaped panel 131 to be closed.

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。 Further, 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 double-folding ruled line covering piece is not provided on the top side connecting piece 1A32, 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 folded in a mountain with respect to the outer surface of the container by both the top side folding ruled line 1A32c and the bottom side folding ruled line 1B32c. By folding in half so as to be, the side surface 122 composed of the top side side surface 1A22 and the bottom side side surface 1B22 and the side surface 123 composed of the top side side surface 1A23 and the bottom side side surface 1B23 are configured. The side surface 122 and the side surface 123 are connected by a fin-shaped panel 132 to be closed.

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。
Then, 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, each side surface 121 to 124 is formed, and a predetermined bending ruled line is formed accordingly. The packaging container 1 can be deformed into a box shape. The box-shaped packaging container 1 has a top surface 1A10 and a bottom surface 1B10, side surfaces 121 to 124 are provided around the top surface 1A10, and fin-shaped panels 131 to 134 are provided between the side surfaces 121 to 124. Is closed, so 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 bending ruled line is provided at the boundary of the bottom side fixing portion 1B40 of the bottom side sheet 1B, and a bending ruled line is provided at the boundary of the top side fixing portion 1A40 of the top side sheet 1A. Therefore, the container fixing portion 140 formed by heat-sealing both fixing portions 1A40 and 1B40 is bent in the direction of the bottom side sheet 1B. That is, the bottom side fixing portion 1B40 is bent in the direction of the bottom side sheet 1B by the bending ruled line provided at the boundary, and the top side fixing portion 1A40 of the top side sheet 1A is not bent at the boundary. It is overlapped with 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 on the outside of the top side fixing portion 1A44 at the position of the top side side surface 1A24, the fixing portion end surface covering piece 1A54 is the end surface of the bottom side fixing portion 1B44. Cover. Then, by adhering the fixing portion end surface covering piece 1A54 to the bottom side 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, in the state of being deformed into the box shape in this way, the fin-shaped panels 131 to 134 folded in half project to the outer surface of the packaging container 1. Therefore, in order to adjust the appearance, it is necessary to lay down the fin-shaped panels 131 to 134 and superimpose them on the side surface 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 folded down, the two-fold ruled line covering pieces 1A54α and 1A54β are folded so as to cover the bottom side two-fold ruled line, and the two-fold ruled line covering pieces 1A54α and 1A54β are packed in a packaging container. By adhering to the side surface of the packaging container, it is possible to prevent the fin-shaped panel from being lifted 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 formed by folding the portion composed of the top side connecting piece 1A33 and the bottom side connecting piece 1B33 in half is tilted down to tilt the top side side surface 1A23 and the bottom side. By overlapping 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 the outer surface side of the top side side surface 1A23, and By tilting the fin-shaped panel 133 so that the region 1A332 adjacent to the top side surface 1A24 overlaps the outer surface side of the region 1A331, the fin-shaped panel 133 is arranged outside the top-side fixing portion 1A44α at a position corresponding to the region 1A332. The bottom side bi-fold rule line 1B33c can be covered with the one-fold rule line covering piece 1A54α. Since the two-fold ruled line coating piece 1A54α protrudes from the bottom side two-fold ruled line 1B33c, the fin-shaped panel 133 is attached to the top side side surface 1A23 and the bottom side side surface 1B23 to form the fin-shaped panel 133 of the packaging container. It is possible to prevent it from rising from the side.

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 composed of 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。 Since the internal volume of the package is increased by being deformed into the box shape in this way, hot water, hot water or cold water can be poured through the spout 1C. Further, as described above, since the package in the box-shaped state is sealed except for the opening of the spout 1C, the hot water or the like does not leak. Then, by shaking the package sufficiently, the contents can be dissolved in boiling 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 disposing of the packaging container 1, it is desirable to deform the empty packaging body into a flat state and dispose of it. In order to deform the box-shaped packaging container 1 into a flat state, first, the fixing portion end face covering piece 1A54 adhered to the bottom side side surface 1B24 is peeled off, and each fin-shaped panel is pulled from the side surface of the packaging container.
