FIG. 4 is a perspective view showing a state in which the lid portions 15R and 15L, the side surface portions 12R and 12L, the front surface portion 13, and the rear surface portion 14 are opened. FIG. 5A is a development view of the packaging container 1, that is, a plan view of a sheet constituting the packaging container 1. The packaging container 1 is formed by folding a sheet. The sheet is formed of, for example, cardboard or cardboard. The sheet may be formed of plastic. FIG. 5B is an enlarged view of region B shown in FIG. 5A. FIG. 5C is an enlarged view of region C shown in FIG. 5A.

以下の説明では、図1及び図5Aに示すX1及びX2の方向をそれぞれ右方向及び左方向と称し、図1及び図5Aに示すY1及びY2の方向をそれぞれ前方及び後方と称する。また、図1に示すZ1、Z2方向をそれぞれ上方及び下方と称する。   In the following description, the directions of X1 and X2 shown in FIGS. 1 and 5A are referred to as the right direction and the left direction, respectively, and the directions of Y1 and Y2 shown in FIGS. Moreover, the Z1 and Z2 directions shown in FIG.

図5Aに示すように、包装容器1は底面部11を有している。包装容器1を構成するシートを折りたたむ過程で、包装容器1によって包装される被収容物G(図4参照)は底面部11に配置される。底面部11は例えば四角形である。   As shown in FIG. 5A, the packaging container 1 has a bottom surface portion 11. In the process of folding the sheet constituting the packaging container 1, the object G (see FIG. 4) packaged by the packaging container 1 is disposed on the bottom surface portion 11. The bottom surface portion 11 is, for example, a quadrangle.

図5Aに示すように、包装容器1は右側面部12Rと左側面部12Lと前面部13と後面部14とを有している(右側面部12R、左側面部12L、前面部13、及び後面部14は請求項の「第1面部」、「第2面部」、「第3面部」、及び「第4面部」にそれぞれ対応している)。右側面部12Rは折り目Faを介して底面部11の縁に接続され、左側面部12Lは折り目Fbを介して底面部11の縁に接続されている。前面部13は折り目Fcを介して底面部11の縁に接続されている。後面部14は折り目Fdを介して底面部11の縁に接続されている。(以下において、各折り目に共通の説明をする場合には、折り目Fと称する)。折り目Fは、折り目Fを介して接続されている2つの面部が折り目Fで折れ曲がるように、他の部位に比べて構造的に弱くなっている。例えば、包装容器1を構成するシートは折り目Fで他の部位に比して薄くなっている。溝が折り目Fに形成されてもよい。図1に示すように、右側面部12Rは折り目Faで折られて包装容器1の右側面を構成し、左側面部12Lは折り目Fbで折られて包装容器1の左側面を構成する。前面部13は折り目Fcで折られて包装容器1の前面を構成し、後面部14は折り目Fdで折られて包装容器1の後面を構成する。包装容器1の展開状態では、右側面部12Rと左側面部12Lは左右方向において底面部11を挟んで互いに反対側に位置し、前面部13と後面部14は前後方向において底面部11を挟んで互いに反対側に位置している。すなわち、包装容器1の展開状態では、右側面部12Rは底面部11の右側に位置し、左側面部12Lは底面部11の左側に位置している。前面部13は底面部11の前側に位置し、後面部14は底面部11の後側に位置している。側面部12R、12L、前面部13、及び後面部14のそれぞれは例えば四角形である。   As shown in FIG. 5A, the packaging container 1 has a right side surface portion 12R, a left side surface portion 12L, a front surface portion 13 and a rear surface portion 14 (the right side surface portion 12R, the left side surface portion 12L, the front surface portion 13 and the rear surface portion 14 are It corresponds to the “first surface portion”, “second surface portion”, “third surface portion”, and “fourth surface portion” in the claims). The right side surface portion 12R is connected to the edge of the bottom surface portion 11 via the fold line Fa, and the left side surface portion 12L is connected to the edge of the bottom surface portion 11 via the fold line Fb. The front surface portion 13 is connected to the edge of the bottom surface portion 11 via a fold line Fc. The rear surface portion 14 is connected to the edge of the bottom surface portion 11 via the fold line Fd. (Hereinafter, the common fold line is referred to as a fold line F). The fold line F is structurally weaker than other parts so that the two surface portions connected via the fold line F bend at the fold line F. For example, the sheet constituting the packaging container 1 is thinner at the folds F than at other parts. A groove may be formed in the crease F. As shown in FIG. 1, the right side surface portion 12R is folded at the fold line Fa to constitute the right side surface of the packaging container 1, and the left side surface portion 12L is folded at the fold line Fb to constitute the left side surface of the packaging container 1. The front surface portion 13 is folded at the fold line Fc to constitute the front surface of the packaging container 1, and the rear surface portion 14 is folded at the fold line Fd to constitute the rear surface of the packaging container 1. In the unfolded state of the packaging container 1, the right side surface portion 12R and the left side surface portion 12L are positioned on opposite sides of the bottom surface portion 11 in the left-right direction, and the front surface portion 13 and the rear surface portion 14 are in contact with each other with the bottom surface portion 11 in the front-back direction. Located on the opposite side. That is, in the unfolded state of the packaging container 1, the right side surface portion 12 </ b> R is located on the right side of the bottom surface portion 11, and the left side surface portion 12 </ b> L is located on the left side of the bottom surface portion 11. The front surface portion 13 is located on the front side of the bottom surface portion 11, and the rear surface portion 14 is located on the rear side of the bottom surface portion 11. Each of the side surface portions 12R, 12L, the front surface portion 13, and the rear surface portion 14 is, for example, a quadrangle.

図5Aに示すように、包装容器1は折り目Feを介して右側面部12Rに接続されている右蓋部15Rと、折り目Ffを介して左側面部12Lに接続されている左蓋部15Lとを有している。包装容器1の展開状態において、右蓋部15Rは右側面部12Rのさらに右側に位置し、左蓋部15Lは左側面部12Lのさらに左側に位置している。右側面部12Rが折り目Faで折られ、左側面部12Lが折り目Fbで折られ、前面部13が折り目Fcで折られ、後面部14が折り目Fdで折られ、さらに、右蓋部15Rが折り目Feで折られ、左蓋部15Lが折り目Ffで折られたとき、右蓋部15R及び左蓋部15Lは底面部11と向き合い、箱状の包装容器1が形成される。このような包装容器1によれば、底面部11より右側の形状(右蓋部15R及び右側面部12R)と、底面部11より左側の形状(左蓋部15L及び左側面部12L)を互いに似せることができる。これにより、包装容器の形状をシンプルにでき、包装容器の製造における効率性を向上できる。   As shown in FIG. 5A, the packaging container 1 has a right lid portion 15R connected to the right side surface portion 12R via a fold line Fe and a left lid portion 15L connected to the left side surface portion 12L via a fold line Ff. doing. In the unfolded state of the packaging container 1, the right lid portion 15R is positioned further to the right side of the right side surface portion 12R, and the left lid portion 15L is positioned further to the left side of the left side surface portion 12L. The right side surface portion 12R is folded at the fold Fa, the left side surface portion 12L is folded at the fold Fb, the front surface portion 13 is folded at the fold Fc, the rear surface portion 14 is folded at the fold Fd, and the right lid portion 15R is folded at the fold Fe. When the left lid portion 15L is folded at the fold line Ff, the right lid portion 15R and the left lid portion 15L face the bottom surface portion 11, and the box-shaped packaging container 1 is formed. According to such a packaging container 1, the shape on the right side from the bottom surface portion 11 (the right lid portion 15R and the right side surface portion 12R) and the shape on the left side from the bottom surface portion 11 (the left lid portion 15L and the left side surface portion 12L) are made to resemble each other. Can do. Thereby, the shape of a packaging container can be simplified and the efficiency in manufacture of a packaging container can be improved.

包装容器1の例では、前後方向での右蓋部15Rの幅は右側面部12Rと実質的に等しい。前後方向での左蓋部15Lの幅は左側面部12Lの幅と実質的に等しい。また、右側面部12R、左側面部12L、及び底面部11の幅も前後方向において実質的に等しい。つまり、右蓋部15Rと左蓋部15Lは前後方向において実質的に等しい幅を有している。後において説明するように、右蓋部15Rと折り込み部16A、16Bとの間に左蓋部15Lが差し込まれる。仮に左蓋部15Lの幅と右蓋部15Rの幅とが完全に等しいと、右蓋部15Rと折り込み部16A、16Bとの間に左蓋部15Lが差し込まれるときに、左蓋部15Lの縁が折り込み部16A、16Bに引っ掛かる可能性がある。これを防止するため、包装容器1の例では前後方向での左蓋部15Lの幅は前後方向での右蓋部15Rの幅より僅かに小さい。具体的には、前後方向での左蓋部15Lの幅は、包装容器1を構成しているシートの厚さ程度、右蓋部15Rの幅より僅かに小さい。これによって、右蓋部15Rと折り込み部16A、16Bとの間に左蓋部15Lをスムーズに差し込むことができる。ここでの説明において、「2つの面部の幅が実質的に等しい」とは、2つの面部の間にシートの厚さ程度の差異があることを許容している。例えば、「前後方向での底面部11の幅は右側面部12Rと実質的に等しい」とは、前後方向での底面部11の幅と前後方向での右側面部12Rの幅との間にシートの厚さ程度の差異があることを許容している。   In the example of the packaging container 1, the width of the right lid portion 15R in the front-rear direction is substantially equal to the right side surface portion 12R. The width of the left lid portion 15L in the front-rear direction is substantially equal to the width of the left side surface portion 12L. Further, the right side surface portion 12R, the left side surface portion 12L, and the bottom surface portion 11 have substantially the same width in the front-rear direction. That is, the right lid portion 15R and the left lid portion 15L have substantially the same width in the front-rear direction. As will be described later, the left lid portion 15L is inserted between the right lid portion 15R and the folding portions 16A and 16B. If the width of the left lid portion 15L and the width of the right lid portion 15R are completely equal, when the left lid portion 15L is inserted between the right lid portion 15R and the folding portions 16A and 16B, the left lid portion 15L There is a possibility that the edge is caught by the folding portions 16A and 16B. In order to prevent this, in the example of the packaging container 1, the width of the left lid portion 15L in the front-rear direction is slightly smaller than the width of the right lid portion 15R in the front-rear direction. Specifically, the width of the left lid portion 15L in the front-rear direction is slightly smaller than the width of the right lid portion 15R by about the thickness of the sheet constituting the packaging container 1. Accordingly, the left lid portion 15L can be smoothly inserted between the right lid portion 15R and the folding portions 16A and 16B. In the description here, “the widths of the two surface portions are substantially equal” means that there is a difference in the thickness of the sheet between the two surface portions. For example, “the width of the bottom surface portion 11 in the front-rear direction is substantially equal to the right side surface portion 12R” means that the sheet is between the width of the bottom surface portion 11 in the front-rear direction and the width of the right side surface portion 12R in the front-rear direction. It is allowed to have a thickness difference.

後において詳説するように、側面部12R、12Lの前縁(折り目Fh)の位置は底面部11の前縁(折り目Fc)に対して前後方向における中心側に僅かにずれている。同様に、側面部12R、12Lの後縁(折り目Fh)の位置は底面部11の後縁(折り目Fd)に対して前後方向における中心側に僅かにずれている。このことによって、側面部12R、12Lの前後方向での幅W4、W5と蓋部15R、15Lの前後方向での幅W6、W7は、底面部11の前後方向での幅W1よりも小さい。そして、左側面部12Lの前後方向での幅W5と左蓋部15Lの前後方向での幅W7は、右側面部12Rの前後方向での幅W4と右蓋部15Rの前後方向での幅W6よりも小さい。   As will be described in detail later, the positions of the front edges (folds Fh) of the side surface parts 12R and 12L are slightly shifted to the center side in the front-rear direction with respect to the front edges (fold lines Fc) of the bottom surface part 11. Similarly, the positions of the rear edges (fold line Fh) of the side surface parts 12R and 12L are slightly shifted toward the center in the front-rear direction with respect to the rear edge (fold line Fd) of the bottom surface part 11. Accordingly, the widths W4, W5 in the front-rear direction of the side surface parts 12R, 12L and the widths W6, W7 in the front-rear direction of the lid parts 15R, 15L are smaller than the width W1 in the front-rear direction of the bottom surface part 11. The width W5 in the front-rear direction of the left side surface portion 12L and the width W7 in the front-rear direction of the left lid portion 15L are larger than the width W4 in the front-rear direction of the right side surface portion 12R and the width W6 in the front-rear direction of the right lid portion 15R. small.

図5Aに示すように、包装容器1は折り込み部16A、16Bを有している。折り込み部16Aは、包装容器1の展開状態において、右蓋部15Rと右側面部12Rの前側に位置し且つ前面部13の右側に位置している。折り込み部16Aは右蓋部15Rと右側面部12Rと前面部13とに折り目Fg、Fh、Fiを介して繋がっている。詳細には、折り込み部16Aは折り目Fg、Fhを介して右蓋部15Rの前縁と右側面部12Rの前縁に繋がっており、折り目Fiを介して前面部13の右縁に繋がっている。折り込み部16Bは、包装容器1の展開状態において、右蓋部15Rと右側面部12Rの後側に位置し且つ後面部14の右側に位置している。折り込み部16Bは右蓋部15Rと右側面部12Rと後面部14とに折り目Fg、Fh、Fiを介して繋がっている。詳細には、折り込み部16Bは、折り目Fg、Fhを介して右蓋部15Rの後縁と右側面部12Rの後縁に繋がっており、折り目Fiを介して後面部14の右縁に繋がっている。   As shown to FIG. 5A, the packaging container 1 has the folding parts 16A and 16B. The folded portion 16A is located on the front side of the right lid portion 15R and the right side surface portion 12R and on the right side of the front surface portion 13 in the unfolded state of the packaging container 1. The folding portion 16A is connected to the right lid portion 15R, the right side surface portion 12R, and the front surface portion 13 through fold lines Fg, Fh, and Fi. Specifically, the folding portion 16A is connected to the front edge of the right lid portion 15R and the front edge of the right side surface portion 12R via the folds Fg and Fh, and is connected to the right edge of the front surface portion 13 via the fold Fi. The folded portion 16B is located on the rear side of the right lid portion 15R and the right side surface portion 12R and on the right side of the rear surface portion 14 in the unfolded state of the packaging container 1. The folding portion 16B is connected to the right lid portion 15R, the right side surface portion 12R, and the rear surface portion 14 via fold lines Fg, Fh, and Fi. Specifically, the folding portion 16B is connected to the rear edge of the right lid portion 15R and the rear edge of the right side surface portion 12R via the folds Fg and Fh, and is connected to the right edge of the rear surface portion 14 via the fold line Fi. .

図3に示すように、前面部13と後面部14をそれぞれ折り目Fc、Fdで折り曲げて底面部11に対して立て、且つ右側面部12Rを折り目Faで折り曲げて底面部11に対して立てたとき、折り込み部16A、16Bは後述する折り目Fjで折られて、右側面部12R及び右蓋部15Rの内面に向けて折り込まれる。すなわち、折り込み部16A、16Bは折り目Fjで折られて、右側面部12R及び右蓋部15Rに重なる。そして、左蓋部15Lは、折り込み部16A、16Bと右蓋部15Rの内面との間に差し込むことができる(図1参照)。これにより、必ずしも接着剤や接着テープなどを使用することなく、蓋部15R、15Lを閉じることができ、包装容器1を箱状に組み立てる作業を効率化できる。左蓋部15Lが折り込み部16A、16Bと右蓋部15Rの内面との間に差し込まれた状態では、前面部13と後面部14の開きは抑えられる。   As shown in FIG. 3, when the front surface portion 13 and the rear surface portion 14 are folded at the folds Fc and Fd, respectively, and are raised with respect to the bottom surface portion 11, and the right side surface portion 12R is folded at the fold line Fa, with respect to the bottom surface portion 11. The folded portions 16A and 16B are folded at a fold Fj described later, and are folded toward the inner surfaces of the right side surface portion 12R and the right lid portion 15R. That is, the folding portions 16A and 16B are folded at the fold line Fj and overlap the right side surface portion 12R and the right lid portion 15R. The left lid portion 15L can be inserted between the folding portions 16A and 16B and the inner surface of the right lid portion 15R (see FIG. 1). Accordingly, the lid portions 15R and 15L can be closed without necessarily using an adhesive or an adhesive tape, and the work of assembling the packaging container 1 into a box shape can be made efficient. In the state where the left lid portion 15L is inserted between the folded portions 16A and 16B and the inner surface of the right lid portion 15R, the opening of the front surface portion 13 and the rear surface portion 14 is suppressed.

図5Aに示すように、右側面部12R及び右蓋部15Rの内面に向けて折り込み部16Aを折り込むことができるように、折り込み部16Aには斜め折り目Fjが形成されている。折り込み部16Aの斜め折り目Fjは底面部11の角から斜めに伸び、前面部13の右縁と右側面部12Rの前縁との間に位置している。折り込み部16Aは、斜め折り目Fjより前面部13側に位置している第1の部分16aと、斜め折り目Fjより右側面部12R及び右蓋部15R側に位置している第2の部分16b及び第3の部分16cとを有している。第2の部分16bは右側面部12Rに接続され、第3の部分16cは右蓋部15Rに接続されている。第2の部分16bと第3の部分16cとの間には、右側面部12Rと右蓋部15Rとの間の折り目Feに沿った方向に伸びている折り目Fkが形成されている。   As shown in FIG. 5A, the folded portion 16A is formed with an oblique fold Fj so that the folded portion 16A can be folded toward the inner surfaces of the right side surface portion 12R and the right lid portion 15R. The oblique fold Fj of the folding portion 16A extends obliquely from the corner of the bottom surface portion 11, and is located between the right edge of the front surface portion 13 and the front edge of the right surface portion 12R. The folding portion 16A includes a first portion 16a located on the front surface portion 13 side from the oblique fold Fj, a second portion 16b located on the right side surface portion 12R and the right lid portion 15R side from the oblique fold Fj, and a second portion. 3 portion 16c. The second portion 16b is connected to the right side surface portion 12R, and the third portion 16c is connected to the right lid portion 15R. A fold Fk extending in a direction along the fold Fe between the right side surface portion 12R and the right lid portion 15R is formed between the second portion 16b and the third portion 16c.

図3に示すように、前面部13を折り目Fcで折って底面部11に対して立てたとき、第1の部分16aは折り目Fiで前面部13に対して内側に折ることができる。第1の部分16aは折り目Fiで約90度折られ、前面部13に対して略直角に配置される。このとき、第2の部分16bは第1の部分16aに対して斜め折り目Fjで約180度折られて、第1の部分16aに重なる。また、第2の部分16bは右側面部12Rの内面に向けて折り目Fhで折られ、第3の部分16cは右蓋部15Rの内面に向けて折り目Fgで折ることができる。第2の部分16bと第3の部分16cは折り目Fh、Fgで約180度折られて、右側面部12Rと右蓋部15Rと向き合うように配置される。その結果、第3の部分16cと右蓋部15Rとの間に、左蓋部15Lを差し込むための受け入れ部(薄い筒状の部位)が形成される。左蓋部15Lは第3の部分16cと右蓋部15Rとの間に差し込むことができる(図1参照)。図2に示すように、右蓋部15Rを右側面部12Rに対して折り目Feで折ったとき、第3の部分16cは折り目Fkで第2の部分16bに対して折られる。   As shown in FIG. 3, when the front surface portion 13 is folded at the fold line Fc and stood with respect to the bottom surface portion 11, the first portion 16 a can be folded inside the front surface portion 13 at the fold line Fi. The first portion 16 a is folded about 90 degrees at the fold Fi, and is disposed substantially at right angles to the front surface portion 13. At this time, the second portion 16b is folded about 180 degrees at the oblique fold Fj with respect to the first portion 16a, and overlaps the first portion 16a. The second portion 16b can be folded at the fold Fh toward the inner surface of the right side surface portion 12R, and the third portion 16c can be folded at the fold Fg toward the inner surface of the right lid portion 15R. The second portion 16b and the third portion 16c are folded at about folds Fh and Fg by about 180 degrees, and are arranged so as to face the right side surface portion 12R and the right lid portion 15R. As a result, a receiving portion (thin cylindrical portion) for inserting the left lid portion 15L is formed between the third portion 16c and the right lid portion 15R. The left lid portion 15L can be inserted between the third portion 16c and the right lid portion 15R (see FIG. 1). As shown in FIG. 2, when the right lid portion 15R is folded at the fold line Fe with respect to the right side surface portion 12R, the third portion 16c is folded at the fold line Fk with respect to the second portion 16b.

包装容器1は、その展開状態では、左右方向に伸びている中心線C1に対して実質的に対称の形状を有しているのが好ましい。図5Aに示すように、包装容器1の例では、右側面部12Rと右蓋部15Rと、後面部14とを繋ぐ折り込み部16Bにも、斜め折り目Fjと折り目Fkとが形成されている。すなわち、折り込み部16Bも第1の部分16a、第2の部分16b、第3の部分16cを有している。折り込み部16Aと折り込み部16Bは完全な対称でもよいし、それらの一部の形状や、サイズが互いに異なっていてもよい。   In the unfolded state, the packaging container 1 preferably has a substantially symmetrical shape with respect to the center line C1 extending in the left-right direction. As shown in FIG. 5A, in the example of the packaging container 1, the diagonal fold Fj and the fold Fk are also formed in the folding portion 16 </ b> B connecting the right side surface portion 12 </ b> R, the right lid portion 15 </ b> R, and the rear surface portion 14. That is, the folding portion 16B also has a first portion 16a, a second portion 16b, and a third portion 16c. The folding portion 16A and the folding portion 16B may be completely symmetric, or some of their shapes and sizes may be different from each other.

図5Aに示すように、包装容器1は折り込み部16C、16Dを有している。折り込み部16Cは、包装容器1の展開状態において、左蓋部15Lと左側面部12Lの前側に位置し且つ前面部13の左側に位置している。折り込み部16Cは、折り込み部16Aと同様に、左蓋部15Lと左側面部12Lと前面部13とに折り目Fg、Fh、Fiを介して繋がっている。折り込み部16Dは、包装容器1の展開状態において、左蓋部15Lと左側面部12Lの後側に位置し且つ後面部14の左側に位置している。折り込み部16Dは左蓋部15Lと左側面部12Lと後面部14とに折り目Fg、Fh、Fiを介して繋がっている。包装容器1は、その展開状態では、前後方向に伸びている中心線C2に対して実質的に対称の形状を有している。包装容器1の例では折り込み部16C、16Dにも、上述の折り込み部16A、16Bと同様、斜め折り目Fjと折り目Fkとが形成されている。すなわち、折り込み部16C、16Dも、第1の部分16a、第2の部分16b、第3の部分16cを有している。折り込み部16C、16Dは折り込み部16A、16Bと完全な対称でもよいし、それらの一部の形状や、サイズが互いに異なっていてもよい。図3に示すように、前面部13と後面部14をそれぞれ折り目Fc、Fdで折り曲げて底面部11に対して立て、且つ左側面部12Lを折り目Fbで折り曲げて底面部11に対して立てたとき、折り込み部16C、16Dは、折り込み部16A、16Bと同様に、左側面部12L及び左蓋部15Lの内面に向けて折り込まれる。   As shown to FIG. 5A, the packaging container 1 has the folding parts 16C and 16D. The folded portion 16C is located on the front side of the left lid portion 15L and the left side surface portion 12L and on the left side of the front surface portion 13 in the unfolded state of the packaging container 1. Similarly to the folding portion 16A, the folding portion 16C is connected to the left lid portion 15L, the left side surface portion 12L, and the front surface portion 13 through folds Fg, Fh, and Fi. The folded portion 16D is located on the rear side of the left lid portion 15L and the left side surface portion 12L and on the left side of the rear surface portion 14 in the unfolded state of the packaging container 1. The folding portion 16D is connected to the left lid portion 15L, the left side surface portion 12L, and the rear surface portion 14 via fold lines Fg, Fh, and Fi. In the unfolded state, the packaging container 1 has a substantially symmetrical shape with respect to the center line C2 extending in the front-rear direction. In the example of the packaging container 1, diagonal folds Fj and folds Fk are also formed in the folding parts 16 </ b> C and 16 </ b> D, similarly to the folding parts 16 </ b> A and 16 </ b> B described above. That is, the folding portions 16C and 16D also have a first portion 16a, a second portion 16b, and a third portion 16c. The folding parts 16C and 16D may be completely symmetrical with the folding parts 16A and 16B, or the shape and size of some of them may be different from each other. As shown in FIG. 3, when the front surface portion 13 and the rear surface portion 14 are folded at the folds Fc and Fd, respectively, and are raised with respect to the bottom surface portion 11, and the left side surface portion 12L is folded at the fold line Fb, and are raised with respect to the bottom surface portion 11. The folding portions 16C and 16D are folded toward the inner surfaces of the left side surface portion 12L and the left lid portion 15L, similarly to the folding portions 16A and 16B.

左蓋部15Lの左縁15bは、その前後方向の中央部が左縁15bの他の部分よりも左方向に位置するように形成されている。包装容器1の例では、左蓋部15Lの左縁15bはその前後方向の中央部が左方向に膨らむように湾曲している。このような左蓋部15Lによれば、左蓋部15Lを右蓋部15Rと折り込み部16A、16Bの間に差し込む作業が容易となる。例えば、左蓋部15Lを右蓋部15Rと折り込み部16A、16Bの間に差し込むときに、左蓋部15Lの左縁15bの端部が折り込み部16A、16Bに当たってしまい、差し込み作業が円滑に進まないことを防ぐことができる。包装容器1の例にかえて、左蓋部15Lの左縁15bは、その前後方向の中央部が左方向に膨らむように、前後方向の中央部で屈曲してもよい。包装容器1の例では、右蓋部15Rの右縁15aは、その前後方向の中央部が右縁15aの他の部分よりも右方向に位置するように形成されている。具体的には、右蓋部15Rの右縁15aも右方向に膨らむように湾曲している。   The left edge 15b of the left lid part 15L is formed such that the center part in the front-rear direction is positioned more to the left than the other part of the left edge 15b. In the example of the packaging container 1, the left edge 15b of the left lid portion 15L is curved so that the center portion in the front-rear direction swells leftward. According to such a left lid portion 15L, it is easy to insert the left lid portion 15L between the right lid portion 15R and the folding portions 16A and 16B. For example, when the left lid portion 15L is inserted between the right lid portion 15R and the folding portions 16A and 16B, the end of the left edge 15b of the left lid portion 15L hits the folding portions 16A and 16B, and the insertion work proceeds smoothly. Can be prevented. Instead of the example of the packaging container 1, the left edge 15b of the left lid portion 15L may be bent at the center portion in the front-rear direction so that the center portion in the front-rear direction swells leftward. In the example of the packaging container 1, the right edge 15a of the right lid part 15R is formed such that the center part in the front-rear direction is positioned to the right of the other part of the right edge 15a. Specifically, the right edge 15a of the right lid portion 15R is also curved so as to swell in the right direction.

図5Aに示すように、折り込み部16A、16B、16C、16Dは外縁16dを有している。包装容器1は外縁16dからさらに外側に張り出す部分を有していない。折り込み部16Aの外縁16dは右蓋部15Rの右縁15aに接続している。折り込み部16Aの外縁16dは右蓋部15Rの右縁15aから前面部13に向かって斜めに伸びている。こうすることにより、例えば、折り込み部16Aが矩形である場合に比べて、展開状態での包装容器1のサイズを小さくできる。その結果、包装容器1を構成するシートの使用量を低減でき、包装容器1の製造を効率化できる。図5Aの例では、折り込み部16Aの外縁16dは湾曲しながら斜めに伸びている。折り込み部16Aの外縁16dは直線的に斜めに伸びてもよい。包装容器1の例では、折り込み部16Aの外縁16dは前面部13の前縁(後述する第1上面部17Aと前面部13との間の折り目Fm)に接続している。折り込み部16Aの外縁16dは必ずしも前面部13の前縁(折り目Fm)に繋がっていなくてもよい。例えば、折り込み部16Aの外縁16dは前面部13の右縁(折り目Fi)に接続してもよい。折り込み部16Aの外縁16dは、図5Aに示すように、前面部13の前縁に沿った方向に伸びている部分16eを有してもよい。図5Aの例に替えて、折り込み部16Aの外縁16dは部分16eを有することなく、その全体において湾曲してもよい。   As shown in FIG. 5A, the folding portions 16A, 16B, 16C, and 16D have an outer edge 16d. The packaging container 1 does not have a portion that protrudes further outward from the outer edge 16d. The outer edge 16d of the folded portion 16A is connected to the right edge 15a of the right lid portion 15R. The outer edge 16d of the folded portion 16A extends obliquely from the right edge 15a of the right lid portion 15R toward the front surface portion 13. By doing so, for example, the size of the packaging container 1 in the unfolded state can be reduced as compared with the case where the folding portion 16A is rectangular. As a result, the usage amount of the sheet constituting the packaging container 1 can be reduced, and the production of the packaging container 1 can be made efficient. In the example of FIG. 5A, the outer edge 16d of the folding portion 16A extends obliquely while being curved. The outer edge 16d of the folded portion 16A may extend obliquely linearly. In the example of the packaging container 1, the outer edge 16 d of the folding portion 16 </ b> A is connected to the front edge of the front surface portion 13 (a fold Fm between the first upper surface portion 17 </ b> A and the front surface portion 13 described later). The outer edge 16d of the folding portion 16A does not necessarily have to be connected to the front edge (fold Fm) of the front surface portion 13. For example, the outer edge 16d of the folding portion 16A may be connected to the right edge (fold Fi) of the front surface portion 13. The outer edge 16d of the folding portion 16A may have a portion 16e extending in the direction along the front edge of the front surface portion 13 as shown in FIG. 5A. Instead of the example of FIG. 5A, the outer edge 16d of the folding portion 16A may be curved in its entirety without having the portion 16e.

他の折り込み部16B、16C、16Dも、折り込み部16Aと同様、斜めに伸びている外縁16dを有している。すなわち、折り込み部16Bの外縁16dは右蓋部15Rの右縁15aから後面部14の後縁に向かって斜めに伸びている。折り込み部16Cの外縁16dは、左蓋部15Lの左縁15bから前面部13の前縁に向かって斜めに伸びている。折り込み部16Dの外縁16dは、左蓋部15Lの左縁15bから後面部14の後縁に向かって斜めに伸びている。その結果、包装容器1は、その展開状態において、略楕円形状を有している。より具体的には、底面部11、側面部12R、12L、前面部13、後面部14、蓋部15R、15Lの外周縁は全体として略楕円形状を有している。包装容器1の例では、この楕円の長軸方向の長さは、左蓋部15Lと左側面部12Lと底面部11と右側面部12Rと右蓋部15Rの左右方向における幅の合計に対応している。この楕円の短軸方向の長さは、前面部13と底面部11と後面部14の前後方向での長さに対応している。   The other folding parts 16B, 16C, and 16D also have outer edges 16d that extend obliquely, similarly to the folding part 16A. That is, the outer edge 16d of the folded portion 16B extends obliquely from the right edge 15a of the right lid portion 15R toward the rear edge of the rear surface portion 14. The outer edge 16d of the folding portion 16C extends obliquely from the left edge 15b of the left lid portion 15L toward the front edge of the front surface portion 13. The outer edge 16d of the folding part 16D extends obliquely from the left edge 15b of the left lid part 15L toward the rear edge of the rear surface part 14. As a result, the packaging container 1 has a substantially elliptical shape in its unfolded state. More specifically, the outer peripheral edges of the bottom surface portion 11, the side surface portions 12R and 12L, the front surface portion 13, the rear surface portion 14, and the lid portions 15R and 15L have a substantially oval shape as a whole. In the example of the packaging container 1, the length of the ellipse in the major axis direction corresponds to the total width in the left-right direction of the left lid portion 15L, the left side surface portion 12L, the bottom surface portion 11, the right side surface portion 12R, and the right lid portion 15R. Yes. The length of the ellipse in the minor axis direction corresponds to the length of the front surface portion 13, the bottom surface portion 11, and the rear surface portion 14 in the front-rear direction.

図5Aに示すように、包装容器1は第1上面部17Aを有している。第1上面部17Aは包装容器1の展開状態において前面部13の前側に位置し、折り目Fmを介して前面部13に接続している。図2及び図3に示すように、包装容器1を閉じた状態で、すなわち、左蓋部15Lが右蓋部15Rと折り込み部16A、16Bとの間に差し込まれた状態で、第1上面部17Aは右蓋部15Rと左蓋部15Lとによって覆われる。このような構造によれば、包装容器1を閉じたときに蓋部15R、15Lと前面部13との隙間から被収容物Gが部分的に露出することを、第1上面部17Aによって抑えることができる。包装容器1はさらに第2上面部17Bを有している。第2上面部17Bは包装容器1の展開状態において後面部14の後側に位置し、折り目Fnを介して後面部14に接続している(図5A参照)。包装容器1を閉じた状態では、第2上面部17Bは右蓋部15Rと左蓋部15Lとによって覆われる。このような構造によれば、包装容器1を閉じたときに蓋部15R、15Lと後面部14との隙間から被収容物Gが露出することを、第2上面部17Bによって抑えることができる。   As shown in FIG. 5A, the packaging container 1 has a first upper surface portion 17A. 17 A of 1st upper surface parts are located in the front side of the front surface part 13 in the expansion | deployment state of the packaging container 1, and are connected to the front surface part 13 through the crease | fold Fm. As shown in FIGS. 2 and 3, the first upper surface portion is in a state where the packaging container 1 is closed, that is, in a state where the left lid portion 15L is inserted between the right lid portion 15R and the folding portions 16A and 16B. 17A is covered with a right lid portion 15R and a left lid portion 15L. According to such a structure, when the packaging container 1 is closed, it is suppressed by the first upper surface portion 17A that the object G is partially exposed from the gap between the lid portions 15R and 15L and the front surface portion 13. Can do. The packaging container 1 further has a second upper surface portion 17B. The 2nd upper surface part 17B is located in the back side of the rear surface part 14 in the unfolded state of the packaging container 1, and is connected to the rear surface part 14 through the fold Fn (refer FIG. 5A). In a state in which the packaging container 1 is closed, the second upper surface portion 17B is covered with the right lid portion 15R and the left lid portion 15L. According to such a structure, when the packaging container 1 is closed, it is possible to prevent the object G from being exposed from the gap between the lid portions 15R and 15L and the rear surface portion 14 by the second upper surface portion 17B.

図5Aに示すように、上面部17A、17Bの前後方向での幅W2は底面部11の前後方向での幅W1よりも小さいのが好ましい。こうすることにより、上面部17A、17Bが包装容器1の他の部位から大きく張り出すことが抑えられるので、展開状態での包装容器1の形状をシンプルにできる。その結果、包装容器1の製造を効率化できる。包装容器1の例では、2つの上面部17A、17Bの幅W2の合計は底面部11の幅W1よりも小さい。こうすることにより、展開状態での包装容器1の形状をさらにシンプルにできる。包装容器1の例では、2つの上面部17A、17Bの幅W2の合計は底面部11の幅W1の半分よりも小さい。また、上面部17A、17Bが折り込み部16A、16B、16C、16Dの外縁16dを延長した円弧の内側に位置するように、上面部17A、17Bの幅W2は設定されてもよい。前後方向での第1上面部17Aの幅と前後方向での第2上面部17Bの幅は必ずしも同じでなくてもよい。   As shown in FIG. 5A, the width W2 in the front-rear direction of the upper surface portions 17A, 17B is preferably smaller than the width W1 in the front-rear direction of the bottom surface portion 11. By doing so, the upper surface portions 17A and 17B can be prevented from overhanging from other parts of the packaging container 1, so that the shape of the packaging container 1 in the unfolded state can be simplified. As a result, the manufacturing of the packaging container 1 can be made efficient. In the example of the packaging container 1, the sum of the widths W <b> 2 of the two upper surface portions 17 </ b> A and 17 </ b> B is smaller than the width W <b> 1 of the bottom surface portion 11. By doing so, the shape of the packaging container 1 in the unfolded state can be further simplified. In the example of the packaging container 1, the sum of the widths W <b> 2 of the two upper surface portions 17 </ b> A and 17 </ b> B is smaller than half of the width W <b> 1 of the bottom surface portion 11. Further, the width W2 of the upper surface portions 17A and 17B may be set so that the upper surface portions 17A and 17B are located inside the arc extending from the outer edge 16d of the folding portions 16A, 16B, 16C, and 16D. The width of the first upper surface portion 17A in the front-rear direction and the width of the second upper surface portion 17B in the front-rear direction are not necessarily the same.

包装容器1の例では、左右方向における上面部17A、17Bの幅は前面部13及び後面部14の左右方向の幅に一致している。上面部17A、17Bの幅は前面部13及び後面部14の左右方向の幅よりも小さくてもよい。この場合、上面部17A、17Bは、包装容器1を閉じたときに、2つの蓋部15R、15Lのうち一方にだけ覆われてもよい。   In the example of the packaging container 1, the widths of the upper surface portions 17 </ b> A and 17 </ b> B in the left-right direction coincide with the widths of the front surface portion 13 and the rear surface portion 14 in the left-right direction. The width of the upper surface portions 17A and 17B may be smaller than the width in the left-right direction of the front surface portion 13 and the rear surface portion 14. In this case, the upper surface portions 17A and 17B may be covered with only one of the two lid portions 15R and 15L when the packaging container 1 is closed.

図5Aに示すように、底面部11は前後方向において幅W1を有している。また、側面部12R、12Lは前後方向において幅W4、W5をそれぞれ有している。包装容器1の例では、幅W4、W5は幅W1よりも小さい。これにより、包装容器1を閉じた状態で、折り込み部16A、16Bと右側面部12Rとの間の折り目Fhの外面H1(図2参照)と、折り込み部16C、16Dと左側面部12Lとの間の折り目Fhの外面H2(図2参照)とに、外部の物が接することを抑えることができる(外面H1は、言い換えれば、右側面部12Rの外面の前縁である。外面H2は、言い換えれば、左側面部12Lの外面の前縁である)。例えば、前面部13或いは後面部14を下側にして包装容器1を床に置く場合に、床が外面H1、H2に接することを抑えることができる。その結果、例えば包装容器1の表面に塗装が施されている場合に、外面H1、H2の塗装に他の部分に触れるのを防ぐことができる。外面H1を有している折り目Fhは、折り込み部16Aの第2の部分16bが右側面部12Rに対して約180折られる部分である。同様に、外面H2を有している折り目Fhは、折り込み部16Cの第2の部分16bが左側面部12Lに対して約180折られる部分である。   As shown in FIG. 5A, the bottom surface portion 11 has a width W1 in the front-rear direction. Further, the side surface portions 12R and 12L have widths W4 and W5 in the front-rear direction, respectively. In the example of the packaging container 1, the widths W4 and W5 are smaller than the width W1. Thereby, with the packaging container 1 closed, the outer surface H1 (see FIG. 2) of the fold Fh between the folded portions 16A, 16B and the right side surface portion 12R, and between the folded portions 16C, 16D and the left side surface portion 12L. An external object can be prevented from coming into contact with the outer surface H2 (see FIG. 2) of the fold line Fh (in other words, the outer surface H1 is a front edge of the outer surface of the right side surface portion 12R. In other words, the outer surface H2 is This is the front edge of the outer surface of the left side surface portion 12L). For example, when the packaging container 1 is placed on the floor with the front surface portion 13 or the rear surface portion 14 facing down, it is possible to suppress the floor from coming into contact with the outer surfaces H1 and H2. As a result, for example, when the surface of the packaging container 1 is coated, it is possible to prevent the outer surfaces H1 and H2 from touching other parts. The fold Fh having the outer surface H1 is a portion where the second portion 16b of the folding portion 16A is folded about 180 with respect to the right side surface portion 12R. Similarly, the fold Fh having the outer surface H2 is a portion where the second portion 16b of the folding portion 16C is folded about 180 with respect to the left side surface portion 12L.

包装容器1は、4本以上の折り目Fが交差する位置に、包装容器1の厚さを減らす部位が形成されている。すなわち、包装容器1の例では、4本以上の折り目Fが交差する位置に、包装容器1を貫通する穴M、Nが形成されている。4本以上の折り目Fが交差する位置に、包装容器1を貫通しない穴M、N(すなわち、凹部)が形成されてもよい。穴M、Nによって、包装容器1の外面が折り目の交点で乱れことなく、包装容器1が組み立てられ得る。4本以上の折り目Fが交差する位置に、折り目Fに沿っており且つ包装容器1を貫通している切り込みが形成されてもよい。切り込みによって、包装容器1の外面が折り目の交点で乱れことなく、包装容器1が組み立てられ得る。   The packaging container 1 is formed with a portion for reducing the thickness of the packaging container 1 at a position where four or more creases F intersect. That is, in the example of the packaging container 1, holes M and N penetrating the packaging container 1 are formed at positions where four or more creases F intersect. Holes M and N (that is, recesses) that do not penetrate the packaging container 1 may be formed at positions where four or more creases F intersect. With the holes M and N, the packaging container 1 can be assembled without disturbing the outer surface of the packaging container 1 at the intersection of the folds. A cut along the fold line F and penetrating the packaging container 1 may be formed at a position where four or more fold lines F intersect. By cutting, the packaging container 1 can be assembled without disturbing the outer surface of the packaging container 1 at the intersection of the folds.

穴Mは底面部11の4つ角に形成されている。図5Bでは、前面部13と底面部11との間の折り目Fc、底面部11と右側面部12Rとの間の折り目Fa、折り込み部16Aと前面部13との間の折り目Fi、折り込み部16Aと右側面部12Rとの間の折り目Fh、及び折り込み部16Aに形成されている斜め折り目Fjとが穴Mに接続している。すなわち、5つの折り目Fの始点が穴Mの縁に位置している。穴Mは例えば円形である。穴Mの形状は円形に限られず、適宜変更されてよい。底面部11の他の3つの角にも、図5Bの穴Mと同様の穴Mが形成されている。穴Mに替えて、折り目Fに沿った切り込みが形成されてもよい。   The holes M are formed at the four corners of the bottom surface portion 11. In FIG. 5B, the fold Fc between the front surface portion 13 and the bottom surface portion 11, the fold Fa between the bottom surface portion 11 and the right side surface portion 12R, the fold Fi between the fold portion 16A and the front surface portion 13, and the fold portion 16A The fold line Fh between the right side surface part 12R and the oblique fold line Fj formed in the folded part 16A are connected to the hole M. That is, the starting points of the five fold lines F are located at the edge of the hole M. The hole M is circular, for example. The shape of the hole M is not limited to a circle, and may be changed as appropriate. Holes M similar to the holes M in FIG. 5B are also formed at the other three corners of the bottom surface portion 11. Instead of the hole M, a cut along the fold line F may be formed.

図5Bに示すように、折り込み部16Aの第2の部分16bと右側面部12Rとの間の折り目Fhは、前面部13と底面部11との間の折り目Fcに対して後方にずれている。同様に、折り込み部16Bの第2の部分16bと右側面部12Rとの間の折り目Fhは、後面部14と底面部11との間の折り目Fdに対して前方にずれている。このことによって、右側面部12Rの前後方向での幅W4は、底面部11の前後方向での幅W1よりも小さくなっている。また、折り込み部16Cの第2の部分16bと左側面部12Lとの間の折り目Fhは、前面部13と底面部11との間の折り目Fcに対して後方にずれている。折り込み部16Dの第2の部分16bと左側面部12Lとの間の折り目Fhは、後面部14と底面部11との間の折り目Fdに対して前方にずれている。このことによって、左側面部12Lの前後方向での幅W5は、底面部11の前後方向での幅W1よりも小さくなっている。   As shown in FIG. 5B, the fold Fh between the second portion 16b of the folding portion 16A and the right side surface portion 12R is shifted rearward with respect to the fold Fc between the front surface portion 13 and the bottom surface portion 11. Similarly, the fold line Fh between the second portion 16b of the folding part 16B and the right side surface part 12R is shifted forward with respect to the fold line Fd between the rear surface part 14 and the bottom surface part 11. Accordingly, the width W4 in the front-rear direction of the right side surface portion 12R is smaller than the width W1 in the front-rear direction of the bottom surface portion 11. Further, the fold Fh between the second portion 16b of the folding portion 16C and the left side surface portion 12L is shifted rearward with respect to the fold Fc between the front surface portion 13 and the bottom surface portion 11. The fold Fh between the second portion 16b of the folding portion 16D and the left side surface portion 12L is shifted forward with respect to the fold Fd between the rear surface portion 14 and the bottom surface portion 11. Accordingly, the width W5 in the front-rear direction of the left side surface portion 12L is smaller than the width W1 in the front-rear direction of the bottom surface portion 11.

図5Aの例に替えて、左右方向における前面部13と後面部14の幅が、左右方向における底面部11の幅よりも小さくてもよい。こうすることによって、包装容器1を閉じた状態で、折り込み部16A、16Cと前面部13との間の折り目Fiの外面と、折り込み部16B、16Dと後面部14との間の折り目Fiの外面とに、外部の物が接することを抑えることができる。   Instead of the example in FIG. 5A, the width of the front surface portion 13 and the rear surface portion 14 in the left-right direction may be smaller than the width of the bottom surface portion 11 in the left-right direction. By doing so, the outer surface of the fold Fi between the folded portions 16A, 16C and the front surface portion 13 and the outer surface of the fold Fi between the folded portions 16B, 16D and the rear surface portion 14 with the packaging container 1 closed. In addition, contact with external objects can be suppressed.

上述したように、包装容器1の例では、左蓋部15Lは、右蓋部15Rと折り込み部16A、16Bとの間に差し込まれる。前後方向における左蓋部15Lの幅W7は、前後方向における右蓋部15Rの幅W6よりも小さい。こうすることで、右蓋部15Rと折り込み部16A、16Bとの間に左蓋部15Lを差し込む作業を円滑に行うことが可能となる。   As described above, in the example of the packaging container 1, the left lid portion 15L is inserted between the right lid portion 15R and the folding portions 16A and 16B. The width W7 of the left lid portion 15L in the front-rear direction is smaller than the width W6 of the right lid portion 15R in the front-rear direction. By doing so, it is possible to smoothly perform the operation of inserting the left lid portion 15L between the right lid portion 15R and the folding portions 16A and 16B.

包装容器1の例では、前後方向での右蓋部15Rの幅W6は右側面部12Rの前後方向での幅W4と同じである。また、前後方向での左蓋部15Lの幅W7は左側面部12Lの前後方向での幅W5と同じである。そして、幅W5、W7は幅W4、W6よりも小さい。上述したように、包装容器1の例では、穴Mに接続している折り目Fの位置を前後方向でずらすことによって、側面部12R、12Lの幅W4、W5を調整している。具体的には、幅W5が幅W4よりも小さくなるように、右側面部12Rの前縁と後縁とに設けられている折り目Fhのずれ幅(底面部11の折り目に対するずれ幅)は、左側面部12Lの前縁と後縁とに設けられている折り目Fhのずれ幅(底面部11の折り目に対するずれ幅)よりも小さい。   In the example of the packaging container 1, the width W6 of the right lid portion 15R in the front-rear direction is the same as the width W4 of the right side surface portion 12R in the front-rear direction. Further, the width W7 of the left lid portion 15L in the front-rear direction is the same as the width W5 of the left side surface portion 12L in the front-rear direction. The widths W5 and W7 are smaller than the widths W4 and W6. As described above, in the example of the packaging container 1, the widths W4 and W5 of the side surfaces 12R and 12L are adjusted by shifting the position of the fold line F connected to the hole M in the front-rear direction. Specifically, the deviation width of the crease Fh provided on the front edge and the rear edge of the right side surface portion 12R (the deviation width of the bottom surface portion 11 with respect to the crease) is set so that the width W5 is smaller than the width W4. It is smaller than the shift width of the fold line Fh provided at the front edge and the rear edge of the surface portion 12L (shift width of the bottom surface section 11 with respect to the fold line).

蓋部15R、15L、側面部12R、12Lの幅の関係は、上述した例に限られない。例えば、右側面部12Rの幅W4と左側面部12Lの幅W5とが同じで、右蓋部15Rの幅W6が側面部12R、12Lの幅W4、W5よりも大きく、左蓋部15Lの幅W7が側面部12R、12Lの幅W4、W5よりも小さくてもよい。   The relationship between the widths of the lid portions 15R and 15L and the side surface portions 12R and 12L is not limited to the above-described example. For example, the width W4 of the right side surface portion 12R is the same as the width W5 of the left side surface portion 12L, the width W6 of the right lid portion 15R is larger than the widths W4, W5 of the side surface portions 12R, 12L, and the width W7 of the left lid portion 15L is It may be smaller than the widths W4 and W5 of the side surface portions 12R and 12L.

図5Aに示すように、包装容器1には4つの穴Nが形成されている。穴Nは、4つの折り目Fの交点に位置している。図5Cに示す穴Nは、折り込み部16Aの第3の部分16cと第2の部分16bとの間の折り目Fkと、右蓋部15Rと右側面部12Rとの間の折り目Fe、右蓋部15Rと第3の部分16cとの間の折り目Fg、及び、右側面部12Rと第2の部分16bとの間の折り目Fhの交点に位置している。図5Cに示すように、穴Nは例えば半円形である。穴Nの形状は必ずしも半円形に限られず、適宜変更されてよい。他の3つの穴Nも、図5Cに示す穴Nと同様に、4つの折り目Fの交点に位置している。包装容器1の例では、半円の穴Nは、その直線部分が折り目Fh、Fgに沿った方向に伸びるように形成されている。   As shown in FIG. 5A, four holes N are formed in the packaging container 1. The hole N is located at the intersection of the four fold lines F. 5C includes a fold Fk between the third portion 16c and the second portion 16b of the folding portion 16A, a fold Fe between the right lid portion 15R and the right side surface portion 12R, and a right lid portion 15R. Is located at the intersection of the fold line Fg between the second part 16c and the fold line Fh between the right side surface part 12R and the second part 16b. As shown in FIG. 5C, the hole N is, for example, semicircular. The shape of the hole N is not necessarily limited to a semicircular shape, and may be changed as appropriate. The other three holes N are also located at the intersections of the four fold lines F, similarly to the hole N shown in FIG. In the example of the packaging container 1, the semicircular hole N is formed such that the straight line portion extends in a direction along the folds Fh and Fg.

図5Cに示すように、右蓋部15Rと第3の部分16cとの間の折り目Fgと、右側面部12Rと第2の部分16bとの間の折り目Fhは前後方向での位置について一致している。そのため、上述したように、右側面部12Rの幅W4と右蓋部15Rの幅W6は同じである。一方、第3の部分16cと第2の部分16bとの間の折り目Fkの位置と、右蓋部15Rと右側面部12Rとの間の折り目Feの位置は左右方向においてずれている。より具体的には、第3の部分16cと第2の部分16bとの間の折り目Fkが、右蓋部15Rと右側面部12Rとの間の折り目Feに対して左右方向の中心側に位置している。これにより、図2及び図3に示すように右蓋部15R及び第3の部分16cを折り目Fe、Fkで折るときに、包装容器1を構成しているシートの厚さが折り目Fk、Feのずれによって吸収される。その結果、その折り作業が容易となる。   As shown in FIG. 5C, the fold line Fg between the right lid part 15R and the third part 16c and the fold line Fh between the right side part 12R and the second part 16b coincide with each other in the front-rear direction. Yes. Therefore, as described above, the width W4 of the right side surface portion 12R and the width W6 of the right lid portion 15R are the same. On the other hand, the position of the crease Fk between the third portion 16c and the second portion 16b and the position of the crease Fe between the right lid portion 15R and the right side surface portion 12R are shifted in the left-right direction. More specifically, the crease Fk between the third portion 16c and the second portion 16b is located on the center side in the left-right direction with respect to the crease Fe between the right lid portion 15R and the right side surface portion 12R. ing. Accordingly, as shown in FIGS. 2 and 3, when the right lid portion 15R and the third portion 16c are folded at the folds Fe and Fk, the thickness of the sheet constituting the packaging container 1 is the folds Fk and Fe. Absorbed by deviation. As a result, the folding operation becomes easy.

図5Cに示す例と同様、左蓋部15Lと折り込み部16Cの第3の部分16cとの間の折り目Fgと、左側面部12Lと第2の部分16bとの間の折り目Fhは前後方向での位置について一致している。一方、折り込み部16Cの第3の部分16cと第2の部分16bとの間の折り目Fkの位置と、左蓋部15Lと左側面部12Lとの間の折り目Ffの位置は左右方向においてずれている。また、左蓋部15Lと折り込み部16Dの第3の部分16cとの間の折り目Fgと、左側面部12Lと第2の部分16bとの間の折り目Fhは前後方向での位置について一致している。一方、折り込み部16Dの第3の部分16cと第2の部分16bとの間の折り目Fkの位置と、左蓋部15Lと左側面部12Lとの間の折り目Ffの位置は左右方向においてずれている。   Similar to the example shown in FIG. 5C, the fold Fg between the left lid portion 15L and the third portion 16c of the folding portion 16C and the fold Fh between the left side surface portion 12L and the second portion 16b are in the front-rear direction. The position is consistent. On the other hand, the position of the fold line Fk between the third part 16c and the second part 16b of the folding part 16C and the position of the fold line Ff between the left lid part 15L and the left side part 12L are shifted in the left-right direction. . Further, the fold Fg between the left lid portion 15L and the third portion 16c of the folding portion 16D and the fold Fh between the left side surface portion 12L and the second portion 16b coincide with each other in the front-rear direction. . On the other hand, the position of the fold line Fk between the third part 16c and the second part 16b of the folding part 16D and the position of the fold line Ff between the left lid part 15L and the left side part 12L are shifted in the left-right direction. .

以上説明したように、包装容器1は、包装容器1は折り目Feを介して右側面部12Rに接続されている右蓋部15Rを有している。また、包装容器1は折り目Ffを介して左側面部12Lに接続されている左蓋部15Lを有している。包装容器1の展開状態において、右蓋部15Rは右側面部12Rのさらに右側に位置し、左蓋部15Lは左側面部12Lのさらに左側に位置している。このような包装容器1によれば、底面部11より右側の形状(右蓋部15R及び右側面部12R)と、底面部11より左側の形状(左蓋部15L及び左側面部12L)を互いに似せることができる。これにより、包装容器の形状をシンプルにでき、包装容器の製造における効率性を向上できる。また、前面部13と後面部14をそれぞれ折り目Fc、Fdで折り曲げて底面部11に対して立て、且つ右側面部12Rを折り目Faで折り曲げて底面部11に対して立てたとき、折り込み部16A、16Bは右側面部12R及び右蓋部15Rの内面に向けて折り込まれる(図3参照)。そして、左蓋部15Lは、折り込み部16A、16Bと右蓋部15Rの内面との間に差し込むことができる。これにより、必ずしも接着剤や接着テープなどを使用することなく、蓋部15L、15Rを閉じることができ、包装容器1を箱状に組み立てる作業を効率化できる。   As described above, the packaging container 1 has the right lid portion 15R that is connected to the right side surface portion 12R via the crease Fe. The packaging container 1 has a left lid portion 15L connected to the left side surface portion 12L via a fold line Ff. In the unfolded state of the packaging container 1, the right lid portion 15R is positioned further to the right side of the right side surface portion 12R, and the left lid portion 15L is positioned further to the left side of the left side surface portion 12L. According to such a packaging container 1, the shape on the right side from the bottom surface portion 11 (the right lid portion 15R and the right side surface portion 12R) and the shape on the left side from the bottom surface portion 11 (the left lid portion 15L and the left side surface portion 12L) are made to resemble each other. Can do. Thereby, the shape of a packaging container can be simplified and the efficiency in manufacture of a packaging container can be improved. Further, when the front surface portion 13 and the rear surface portion 14 are folded at the folds Fc and Fd, respectively, and are raised with respect to the bottom surface portion 11, and when the right side surface portion 12R is folded at the fold line Fa and are raised with respect to the bottom surface portion 11, the folding portions 16A, 16B is folded toward the inner surfaces of the right side surface portion 12R and the right lid portion 15R (see FIG. 3). The left lid portion 15L can be inserted between the folding portions 16A and 16B and the inner surface of the right lid portion 15R. Accordingly, the lid portions 15L and 15R can be closed without necessarily using an adhesive or an adhesive tape, and the work of assembling the packaging container 1 into a box shape can be made efficient.
