Description

本発明は、蓋開口部を予め施した切込ラインに沿って容易に開口することができる開蓋用切込ライン付箱形容器に関する。   The present invention relates to a box-shaped container with a cutting line for opening the lid, which can be easily opened along a cutting line in which a lid opening is provided in advance.

蓋開口部を予め施した切込ラインに沿って開口することができる開蓋用切込ライン付箱形容器は従来から広く知られている（特許文献１〜３参照。）。   2. Description of the Related Art Conventionally, a box-shaped container with a cutting line for opening a lid that can be opened along a cutting line that has been previously provided with a lid opening is widely known (see Patent Documents 1 to 3).

これら開蓋用切込ライン付箱形容器は、いずれも大きな天板部が蓋体となっており、側板に設けた切り離し開封片を持って引き上げると、開封力の作用方向にほぼ沿って蓋体の周囲に予め設けた比較的大きな切込からなる切込ラインに沿って蓋体を開封することができるように構成してある。   All of these box-type containers with a cutting line for opening the lid have a large top plate as a lid, and when they are pulled up by holding the cut-off piece provided on the side plate, the lid almost follows the direction of the opening force. The lid body can be opened along a cutting line made of a relatively large cut provided in advance around the body.

切込ラインも、くの字状不連続切込（特許文献１参照。）、Ｙ字状不連続切込（特許文献２参照。）或いは、長尺の切込と短尺の切込を混用したもの（特許文献３参照。）等が用いられている。   As for the incision line, a dog-shaped discontinuous cut (see Patent Document 1), a Y-shaped discontinuous cut (see Patent Document 2), or a long cut and a short cut are mixed. The thing (refer patent document 3) etc. are used.

従来の切込ラインは、開封力の作用方向に沿って設けてあると共に、それを施した天板や側板の紙質に起因して、例えば、段ボール用紙やボール紙のような厚紙や板紙からなる、比較的硬質で板状を維持し易い箱形容器に施したものであるから、切込ラインに沿って連結部と切込が比較的大きな間隔で大きく設けてあり、簡単に破り取りやすい紙質に適したものであった。   The conventional cutting line is provided along the direction of action of the opening force, and is made of cardboard or cardboard, such as corrugated cardboard or cardboard, for example, due to the paper quality of the top board or side board to which it is applied. Because it is a box-shaped container that is relatively hard and easy to maintain a plate shape, the connecting part and the cut are provided at large intervals along the cut line so that it is easy to tear. It was suitable for.

しかしながら、食料品等を収容する箱形容器は、小型で外周表面に食欲をそそるような調理イメージ等の美しい印刷を施し、調理方法、品質表等を表示して展示すると共に、外部から簡単に悪戯されない堅牢さも必要とする関係上、比較的上質な破れ難い紙質やコーティングを施した箱形容器が採用されていると共に、開封用の切込ラインも箱の縁部に沿って比較的小さく開封しにくい位置に設けてあった。   However, the box-shaped container that holds food items is small and beautifully printed with an appetizing cooking image on the outer peripheral surface, displaying the cooking method, quality table, etc., and easily displayed from the outside. Due to the need for robustness that is not mischievous, a relatively high-quality box-shaped container with hard-to-break paper quality and coating is adopted, and the opening cutting line is also relatively small along the edge of the box It was provided in a position where it was difficult to do.

従って、従来の連結部と切込が比較的大きくそれぞれの間隔を大きく設けた切込ラインでは、切込が不連続となる連結部分で切込ラインの連続性が失われ、目的とする切込ラインに沿って開封することが困難になり、途中から蓋体が千切れてしまう恐れがあった。また、連結部を小さくすると切込が大きい分だけ開封は容易であるが破れやすくなる課題があった。   Therefore, in a conventional cutting line that has a relatively large cut and a large gap between each other, the continuity of the cut line is lost at the connecting part where the cut is discontinuous, and the target cut It became difficult to open along the line, and there was a risk that the lid would be torn off from the middle. Further, when the connecting portion is made small, opening is easy because the cut is large, but there is a problem that it is easily broken.

また、連結部と切込とが交互にミシン目状に連なる比較的強靱な細目切込ラインを設けたものでは、連結が強固で容易に破れにくい反面、細目切込ラインに交差する方向の開蓋力によって、切込ラインから外れた交差方向に蓋片部が切断して破れてしまう傾向があった。   In addition, in the case where a relatively tough fine cut line is provided in which the connecting portions and cuts are alternately connected in a perforated pattern, the connection is strong and not easily broken, but in the direction intersecting the fine cut lines. Due to the lid force, there was a tendency that the lid piece part was cut and broken in the crossing direction deviating from the cutting line.

An opening lid formed by providing guide cutting lines with alternating portions, and forming opening pieces on the side portions of the central portion away from the guide cutting lines by a U-shaped or arc-shaped cutting line for opening pieces In a box-shaped container with a cutting line for use, a guide cut of the guide cut line is provided with a branch cut portion in a U-shape and a connecting portion is provided between the branch cut portion and the guide cut. The connecting portion between the branch cut portion and the guide cut portion is provided at different intervals so as to be small at the central portion and large at the end portion along the longitudinal direction from the central portion to the end portion of the guide cut line. Guide notch provided by the connecting part by having a configuration The strength is weak at the initial center and can be strengthened on both sides, the connection state of the lid opening is firmly maintained along the incision line, and a small connection is required where a large force is first required when opening the lid. There is an effect that the portion can be arranged to reduce the opening force along the cutting line so that the cover can be smoothly opened with a substantially uniform opening force as a whole.

また、本発明は、請求項１に記載の開蓋用切込ライン付箱形容器において、前記枝切込部を、ガイド切込ラインの中央部分から末端部分に向かう長手方向に沿って中央部分では大きく末端部分では小さくなるように長さを変えて設けてなる構成を有することにより、ガイド切込ラインに交差する方向の開蓋力によって、切込ラインから外れた交差方向に蓋片部が切断した場合等に、枝切込部によって開蓋時において最初に大きな力を要する開封片用切込ラインに近いところに大きな枝切込を配してガイド切込ラインから大きく外れるのを接続させ、外れる距離が小さくなるに開封片用切込ラインから離れたところは小さい枝切込で円滑に開蓋できるようにすることができる効果がある。   Further, the present invention provides the box-shaped container with a cutting line for opening the lid according to claim 1, wherein the branch cutting part is arranged along the longitudinal direction from the central part of the guide cutting line toward the terminal part. Then, by having a configuration in which the length is changed so that it is large and small at the end portion, the lid piece in the crossing direction deviating from the cutting line by the lid opening force in the direction crossing the guide cutting line. When cutting, etc., a large branch cut is placed near the opening line for the opening piece that requires a large force when the lid is opened by the branch cut portion so that it is largely disconnected from the guide cut line. When the distance away from the opening line for the opening piece becomes small, the opening can be smoothly opened with a small branch cut.

従って、箱形容器の搬送、展示、保管時等において、ガイド切込ラインがその連結部の連結力によって蓋開口部を開蓋しないように維持すると共に、開蓋時には、開封片の開封片用切込ラインに連結するガイド切込によってガイド切込ラインに沿って迅速、円滑、容易に開蓋部を切断することができるから、ガイド切込ラインに交差する方向の開蓋力によっても、ガイド切込ラインから外れた交差方向に蓋片部が切断するようなことがなくなり、安心して開蓋することができる効果がある。   Therefore, when the box-shaped container is transported, displayed, stored, etc., the guide cutting line keeps the lid opening portion from opening by the connecting force of the connecting portion, and at the time of opening, it is used for opening the opening piece. Since the guide opening connected to the cutting line can cut the opening part quickly, smoothly and easily along the guide cutting line, the guide opening force in the direction crossing the guide cutting line The lid piece is not cut in the crossing direction away from the cutting line, and the lid can be opened with peace of mind.
