As such a paper container, as shown in the developed view in FIG. 4, the body front panel 5 and the body are connected to each other via the body vertical fold lines 2, 3 and 4 where the square tubular body 1 is formed. The left and right side panels 6 and 7 and the back panel 8 of the body are connected to the front panel 5 of the body and the back panel 8 of the body where the bottom 9 is formed via the first bottom horizontal folding lines 10 and 11. The first inner bottom panel 12, the second outer bottom panel 13, and the first inner bottom panel 16 and the second inner bottom panel 17 are connected to the body left and right side panels 6 and 7 via the second bottom horizontal folding lines 14 and 15. The first inner bottom panel 16 and the second inner bottom panel 17 have the second bottom horizontal folding lines 14 and 15 as the bases, respectively, and reach the tips of the first inner bottom panel 16 and the second inner bottom panel 17. A first bent ruled line 19 composed of two diagonal lines forming a second-order triangle with a vertex 18 defined at a non-position, a vertex 18 of the first bent ruled line 19, a first inner bottom panel 16, a second inner bottom panel 17 A second bent ruled line 20 is provided to connect the tip edge of the paper, and is located between the first inner bottom panel 16, the second inner bottom panel 17, the first inner bottom panel 16, and the second inner bottom panel 17. 1 The outer bottom panel 12 is provided with a third bent ruled line 21 connecting the vertices 18 of the two first bent ruled lines 19, and the first inner bottom panel 16, the second inner bottom panel 17, and the first outer bottom panel 12 are formed. It is formed shorter than the second outer bottom panel 13 located between the other side of the first inner bottom panel 16 and the second inner bottom panel 17, and the tip sides 16a, 17a of the first inner bottom panel 16 and the second inner bottom panel 17 are formed. However, it has a tapered shape that connects the position of the second fold ruled line 20 to the tip end side 13a of the second outer bottom panel 13, and the first bottom horizontal fold line while folding the first fold ruled line 19 and the second fold ruled line 20 in a valley. Fold the first outer bottom panel 12, the second outer bottom panel 13, the first inner bottom panel 16, and the second inner bottom panel 17 inward by folding the second bottom horizontal folding lines 14 and 15 in a mountain manner. 1 The tip portions of the inner bottom panel 16, the second inner bottom panel 17, and the first outer bottom panel 12 are bent outward from the third bent ruled line 21, and the first inner bottom panel 16 and the second are not bent at the bent portion. A paper container is known in which the tip portions of the inner bottom surface panel 17 and the second outer bottom surface panel 13 are overlapped and sealed to form the bottom portion 9 (see, for example, Patent Document 1).
このようして形成された紙容器の底部９は、図５に示すように、第１内側底面パネル１６、第２内側底面パネル１７及び第１外側底面パネル１２の先端部を第３折り曲げ罫線２１から外側に折り曲げ、この折り曲げ部に第１内側底面パネル１６、第２内側底面パネル１７及び第２外側底面パネル１３の先端部を重ねてシールされたシール部２２にあって、第１外側底面パネル１２の先端片１２ａが第２外側底面パネル１３の先端部で覆われ、第１外側底面パネル１２の先端片１２ａの端縁が第２外側底面パネル１３の先端辺１３ａから露出しないので、密封性の向上が図れ、また静置安定性が良くなるとされている（例えば特許文献１参照。）。
As shown in FIG. 5, the bottom 9 of the paper container thus formed has a third bent ruled line 21 at the tip of the first inner bottom panel 16, the second inner bottom panel 17, and the first outer bottom panel 12. The first outer bottom panel is located in the sealing portion 22 which is bent outward from the outside and the tips of the first inner bottom panel 16, the second inner bottom panel 17, and the second outer bottom panel 13 are overlapped and sealed on the bent portion. The tip piece 12a of the 12 is covered with the tip portion of the second outer bottom panel 13, and the edge of the tip piece 12a of the first outer bottom panel 12 is not exposed from the tip side 13a of the second outer bottom panel 13, so that the sealing property is sealed. It is said that this can be improved and the static stability is improved (see, for example, Patent Document 1).
しかし、特許文献１に記載されているような紙容器によれば、図５に示すように、底部９のシール部２２の角部２２ａが底部９の側辺に存在し、シール部２２の角部２２ａと第１外側底面パネル１２の段差が大きく、しかも角張っているため、取り扱い中に手に傷を付けたり、また、搬送時などにあって他の紙容器と擦れたとき傷つけてしまうおそれがあり、また、底部９のシール部２２の角部２２ａは目立つので、紙容器の意匠性を損ねてしまうといった問題がある。
However, according to the paper container as described in Patent Document 1, as shown in FIG. 5, the corner portion 22a of the seal portion 22 of the bottom portion 9 exists on the side side of the bottom portion 9, and the corner portion 22 of the seal portion 22 exists. Since the step between the portion 22a and the first outer bottom panel 12 is large and angular, there is a risk of scratching the hand during handling or rubbing against another paper container during transportation or the like. In addition, since the corner portion 22a of the seal portion 22 of the bottom portion 9 is conspicuous, there is a problem that the design of the paper container is impaired.
本発明の目的は、底部におけるシール部の角部の角を落とし、取り扱い中に人の手や他の紙容器への傷つけを防止して安全性を図り、さらには紙容器の意匠性の向上を図ることができる紙容器を提供することにある。

A protruding edge portion 25 is formed on the surface. The shape of the notch line 23 is not particularly limited as long as the protruding edge portion 25 capable of reliably sealing the bottom portion can be formed. The shape of the diagonal line 23a constituting the notch line 23 is not limited to a straight line, and may be an arc shape. Further, by making the inclination of the diagonal line 23a gentle, the amount of paper used can be reduced.
そして、第１折り曲げ罫線１９、第２折り曲げ罫線２０を谷折りしながら第１底部横折線１０，１１、第２底部横折線１４，１５を山折りして第１外側底面パネル１２、第２外側底面パネル１３と第１内側底面パネル１６、第２内側底面パネル１７を内側へ折り畳み、第１内側底面パネル１６、第２内側底面パネル１７及び第１外側底面パネル１２の先端部を第３折り曲げ罫線２１から外側に折り曲げ、この折り曲げ部に、折り曲げていない第１内側底面パネル１６、第２内側底面パネル１７及び第２外側底面パネル１３の先端部を重ねてシールして底部９を形成している。
Then, while folding the first fold ruled line 19 and the second fold ruled line 20 in a valley fold, the first bottom horizontal fold lines 10 and 11 and the second bottom horizontal fold lines 14 and 15 are mountain-folded to form the first outer bottom panel 12 and the second outer side. The bottom panel 13, the first inner bottom panel 16, the second inner bottom panel 17 are folded inward, and the tips of the first inner bottom panel 16, the second inner bottom panel 17, and the first outer bottom panel 12 are folded into a third folding ruled line. The bottom portion 9 is formed by bending outward from 21 and superimposing and sealing the tip portions of the first inner bottom surface panel 16, the second inner bottom surface panel 17, and the second outer bottom surface panel 13 which are not bent. ..
このように構成された紙容器によれば、第２外側底面パネル１３は、先端方向の長さを第１内側底面パネル１６、第２内側底面パネル１７及び第１外側底面パネル１２より長く形成し、第２外側底面パネル１３の先端辺１３ａの両側には、第１内側底面パネル１６、第２内側底面パネル１７の先端辺１６ａ，１７ａに繋がり先端方向に傾斜した斜線２３ａと、斜線２３ａの先端から第２外側底面パネル１３の先端辺１３ａに繋がる略直線２３ｂとからなる切り欠き線２３から切り欠いた切り欠き部２４を形成したので、第１内側底面パネル１６、第２内側底面パネル１７及び第１外側底面パネル１２の先端部を第３折り曲げ罫線２１から外側に折り曲げ、この折り曲げ部に折り曲げていない第１内側底面パネル１６、第２内側底面パネル１７及び第２外側底面パネル１３の先端部を重ねてシールされたシール部２２にあって、第２外側底面パネル１３の先端辺１３ａの両側に形成した切り欠き部２４によってシール部２２の角を落とすことがきる。
According to the paper container configured in this way, the second outer bottom panel 13 has a length in the tip direction longer than the first inner bottom panel 16, the second inner bottom panel 17, and the first outer bottom panel 12. On both sides of the tip side 13a of the second outer bottom panel 13, a diagonal line 23a connected to the first inner bottom panel 16 and the tip sides 16a and 17a of the second inner bottom panel 17 and inclined toward the tip, and the tip of the diagonal line 23a. Since the notch portion 24 notched from the notch line 23 composed of the substantially straight line 23b connected to the tip end side 13a of the second outer bottom panel 13 is formed, the first inner bottom panel 16, the second inner bottom panel 17, and the second inner bottom panel 17 are formed. The tip of the first outer bottom panel 12 is bent outward from the third bent ruled line 21, and the tips of the first inner bottom panel 16, the second inner bottom panel 17, and the second outer bottom panel 13 that are not bent at the bent portion are bent. The corners of the seal portion 22 can be dropped by the cutout portions 24 formed on both sides of the tip side 13a of the second outer bottom panel 13 in the seal portion 22 sealed by stacking the above.
これにより、底部９の側辺に現れるシール部の角部は２２ａは角張っていないので、取り扱い中に人の手や他の紙容器への傷つけてしまうおそれがなく、また、紙容器の意匠性を損なうことがない。また、第２外側底面パネル１３に切り欠き部２４を形成することにより紙の使用量を減らすことができる。
As a result, the corners of the seal portion appearing on the side side of the bottom portion 9 are not angular at 22a, so that there is no risk of damaging human hands or other paper containers during handling, and the design of the paper container Does not spoil. Further, the amount of paper used can be reduced by forming the cutout portion 24 in the second outer bottom panel 13.
また、第２外側底面パネル１３に切り欠き部２４を形成しても、第２外側底面パネル１３の先端の中央部位に突出縁部２５を形成しているので、内側へ折り畳まれたときに突き合わせになる第１内側底面パネル１６と第２内側底面パネル１７の第２折り曲げ罫線２０で折り曲げられた折り曲げ端部の端縁を突出縁部２４で確実に被覆してシールすることができ、シール部２２の密封性を損ねるおそれはない。
Further, even if the cutout portion 24 is formed in the second outer bottom panel 13, the protruding edge portion 25 is formed in the central portion of the tip of the second outer bottom panel 13, so that the cutout portion 25 is abutted when folded inward. The edge of the bent end portion bent by the second folding ruled line 20 of the first inner bottom panel 16 and the second inner bottom panel 17 can be reliably covered with the protruding edge portion 24 to seal the seal portion. There is no risk of impairing the sealing performance of 22.
