Description

本発明は、カートンに関する。 The present invention relates to a carton.

従来、開封用の引裂帯を備えたカートンが知られている（例えば、特許文献１、２参照）。
特許文献１に記載の外装箱（カートン）は、切裂帯（引裂帯）を形成するライナカット線を有している。このライナカット線は、端部が引裂帯側に傾斜したジッパ形状とされている。
特許文献２に記載の段ボール箱（カートン）は、その内面に開封用のカットテープが貼付されている。 Conventionally, a carton provided with a tear zone for opening is known (see, for example, Patent Documents 1 and 2).
The outer box (carton) described in Patent Document 1 has a liner cut line forming a tear zone (tear zone). This liner cut wire has a zipper shape whose end is inclined toward the tear zone side.
The corrugated cardboard box (carton) described in Patent Document 2 has a cut tape for opening attached to the inner surface thereof.

特開２００８−２８００４７号公報Japanese Unexamined Patent Publication No. 2008-28074 特開２００３−２４６３２０号公報Japanese Unexamined Patent Publication No. 2003-246320

しかしながら、特許文献１に記載されたような従来のカートンは、引裂帯の開封方向が限られており、一方向にしか開封することができないという問題がある。
また、特許文献２に記載されたような従来のカートンは、カットテープを使用するため、カットテープのコストや、カットテープをカートンに貼付するコストが掛かってしまい、コストが増加するという問題がある。 However, the conventional carton as described in Patent Document 1 has a problem that the tear zone can be opened in only one direction because the opening direction of the tear zone is limited.
Further, since the conventional carton as described in Patent Document 2 uses a cut tape, there is a problem that the cost of the cut tape and the cost of attaching the cut tape to the carton are incurred, which increases the cost. ..

本発明の目的は、コストの増加を防止しつつ、引裂帯を両方向から開封できるカートンを提供することにある。 An object of the present invention is to provide a carton capable of opening a tear zone from both directions while preventing an increase in cost.

本発明のカートンは、開封用の引裂帯を備え、前記引裂帯は、それぞれ複数の切目が前記引裂帯の開封方向に断続して列をなす一対の切断線で形成され、一方の切断線は、前記開封方向に向かって他方の切断線から離間するように形成された第１切目と、前記開封方向に向かって前記他方の切断線に接近するように形成された第２切目とを備え、前記第１切目の前記開封方向の始端部と、前記第２切目の前記開封方向の終端部とは、前記開封方向に平行な第１直線上に並ぶとともに、それぞれの向きが前記開封方向と一致し、前記第１切目の前記開封方向の終端部と、前記第２切目の前記開封方向の始端部とは、前記開封方向に平行な第２直線上に並ぶとともに、それぞれの向きが前記開封方向と一致することを特徴とする。 The carton of the present invention includes a tear zone for opening, each of which is formed by a pair of cutting lines in which a plurality of cuts are intermittently arranged in a row in the opening direction of the tear zone, and one cutting line is formed. A first cut formed so as to be separated from the other cutting line in the opening direction, and a second cut formed so as to approach the other cutting line in the opening direction. The start end of the first cut in the opening direction and the end of the second cut in the opening direction are aligned on a first straight line parallel to the opening direction, and their respective directions are one with the opening direction. The end portion of the first cut in the opening direction and the start end portion of the second cut in the opening direction are aligned on a second straight line parallel to the opening direction, and their respective directions are in the opening direction. It is characterized by matching with.

本発明によれば、引裂帯が切断線で形成されるため、カットテープを使用する必要がなく、コストの増加を防止することができる。
また、切断線の第１切目の端部と第２切目の端部とが、開封方向に平行な直線上に並ぶとともに、各端部の向きが開封方向と一致する。このため、引裂帯を開封方向の一方側および他方側の何れの側から開封しても、切断線が第１切目と第２切目との間の断続部分で確実に切断されるので、引裂帯を両方向から開封することができる。
従って、コストの増加を防止しつつ、引裂帯を両方向から開封できるカートンを提供することができる。 According to the present invention, since the tear zone is formed by the cutting line, it is not necessary to use a cutting tape, and an increase in cost can be prevented.
Further, the end of the first cut and the end of the second cut of the cutting line are lined up on a straight line parallel to the opening direction, and the direction of each end coincides with the opening direction. Therefore, even if the tear zone is opened from either one side or the other side in the opening direction, the cutting line is surely cut at the intermittent portion between the first cut and the second cut, so that the tear zone is cut. Can be opened from both directions.
Therefore, it is possible to provide a carton capable of opening the tear zone from both directions while preventing an increase in cost.

以上の引裂帯２を有している段ボール箱１において、引裂帯２を開封方向Ａの一方側である一方の内フラップ１４の端部２１側から開封する際は、当該端部２１を把持して手前側に折り返すように引き起しつつ、一方の内フラップ１４と連接する側面部１３側に引っ張る。これにより、引裂帯２が第１切断線３および第２切断線４に沿って切断され、引裂帯２が内フラップ１４から側面部１３に移行する。移行した引裂帯２は、他方の内フラップ１４の端部２２まで開封されることで、段ボール箱１から切断される。そして、もう一方の側面部１３側も引裂帯２を同様に開封することで、上面部１１と底面部１２を切り離すことができる。
一方、引裂帯２を他方の端部２２側から開封方向Ｂの方向に開封する際は、当該端部２２を把持して前記方法と同様に一方の端部２１側に向かって開封することができる。この場合、第１切目３１は第２切目３２として機能し、第２切目３２は第１切目３１として機能する。
なお、内フラップ１４から側面部１３に移行する際や、側面部１３から内フラップ１４に移行する際は、補助線３３、３４があることで移行しやすくなる。 In the corrugated cardboard box 1 having the above-mentioned tear zone 2, when opening the tear zone 2 from the end 21 side of one inner flap 14 which is one side of the opening direction A, the end 21 is gripped. While pulling it back toward you, pull it toward the side surface 13 that is connected to one of the inner flaps 14. As a result, the tear zone 2 is cut along the first cutting line 3 and the second cutting line 4, and the tear zone 2 moves from the inner flap 14 to the side surface portion 13. The transferred tear zone 2 is cut from the cardboard box 1 by opening up to the end 22 of the other inner flap 14. Then, by opening the tear zone 2 on the other side surface portion 13 side in the same manner, the upper surface portion 11 and the bottom surface portion 12 can be separated.
On the other hand, when opening the tear zone 2 from the other end 22 side in the opening direction B, the end 22 may be grasped and opened toward one end 21 side in the same manner as in the above method. can. In this case, the first cut 31 functions as the second cut 32, and the second cut 32 functions as the first cut 31.
When shifting from the inner flap 14 to the side surface portion 13, or when shifting from the side surface portion 13 to the inner flap 14, the presence of the auxiliary lines 33 and 34 facilitates the transition.

以上のような実施形態によれば、引裂帯２が第１切断線３および第２切断線４で形成されるため、カットテープを使用する必要がなく、コストの増加を防止することができる。
また、第１切目３１の始端部３１Ａと第２切目３２の終端部３２Ｂとが、開封方向Ａに平行な第１直線Ｌ１上に並ぶとともに、それぞれの向きが開封方向Ａと一致し、第１切目３１の終端部３１Ｂと第２切目３２の始端部３２Ａとが、開封方向Ａに平行な第２直線Ｌ２上に並ぶとともに、それぞれの向きが開封方向Ａと一致する。このため、引裂帯２を開封方向Ａの一方側および他方側の何れの側から開封しても、第１切断線３が第１切目３１と第２切目３２との間の断続部分で確実に切断されるので、引裂帯２を両方向から開封することができる。
従って、コストの増加を防止しつつ、引裂帯２を両方向から開封できる段ボール箱１を提供することができる。 According to the above embodiment, since the tear zone 2 is formed by the first cutting line 3 and the second cutting line 4, it is not necessary to use a cutting tape, and an increase in cost can be prevented.
Further, the start end portion 31A of the first cut 31 and the end portion 32B of the second cut 32 are lined up on the first straight line L1 parallel to the opening direction A, and their respective directions coincide with the opening direction A. The end portion 31B of the cut 31 and the start end portion 32A of the second cut 32 are lined up on the second straight line L2 parallel to the opening direction A, and their respective directions coincide with the opening direction A. Therefore, even if the tear zone 2 is opened from either one side or the other side of the opening direction A, the first cutting line 3 is surely formed at the intermittent portion between the first cut 31 and the second cut 32. Since it is cut, the tear zone 2 can be opened from both directions.
Therefore, it is possible to provide a corrugated cardboard box 1 capable of opening the tear zone 2 from both directions while preventing an increase in cost.

また、第１切断線３が波形状とされているため、引裂帯２の幅寸法を部分的に大きくすることができ、引裂帯２の剛性を高めることができる。 Further, since the first cutting line 3 has a wavy shape, the width dimension of the tear zone 2 can be partially increased, and the rigidity of the tear zone 2 can be increased.
