本考案は、鶏卵パツク等のように合成樹脂製薄
シートにて、パツク本体とカバー体とが屈曲自在
な蝶番部を介して一体的に連接するように成形さ
れた包装用容器に関するものである。[Detailed description of the invention] [Industrial application field] The present invention uses a synthetic resin thin sheet such as egg packs, and the pack body and cover body are integrated through a bendable hinge part. The present invention relates to packaging containers formed so as to be articulated.
前記のように合成樹脂製薄シートにてパツク本

知の通りである。
As mentioned above, the packaging container is formed of a thin synthetic resin sheet so that the pack body and the cover body are integrally connected via a bendable hinge, and the contents can be placed inside the pack body. After that, the cover body is folded at the hinge part to cover the pack body, and the flange part around the pack body and the flange part around the cover body are stapled or heated on the side opposite to the hinge part. It is well known that the parts are partially fixed and sealed by welding or the like.

が破れたはずみで、容器の全体が転倒して内容物
が散乱する危険があり、特に、内容物として重い
鶏卵を入れた鶏卵パツクの場合には、前記の危険
性は一層増大するのである。 To open this type of container, the flange of the pack body and the flange of the cover body must be grasped with fingertips and pulled in opposite directions to break the staples or heat welds. In this case, there is a risk that the stapler or heat welded part will break and the entire container will fall over and the contents will be scattered, especially in the case of egg packs containing heavy eggs. The above-mentioned risks are further increased.
そこで、先行技術としての実公昭52−40992号
公報は、パツク本体とカバー体とを連接する屈曲
自在な蝶番部に、当該蝶番部に沿つてミシン目状
の切目線を一条又は二条刻設し、この切目線に沿
つて蝶番部を切り裂くことを提案している。 Therefore, as a prior art, Japanese Utility Model Publication No. 52-40992 discloses that one or two perforation-like cut lines are carved along the bendable hinge part that connects the pack body and the cover body. , suggests cutting the hinge part along this cut line.
しかし、このミシン目状の切目線に沿つての切

切り裂きが困難になると言うように、開蓋の容易
性と、容器自体の強度低下とが相反する点に問題
があつた。 However, if the intervals between the score lines are narrowed in order to make it easier to tear along the perforation-like score lines, the locations along the score lines may be accidentally torn during the manufacturing and transportation of the container. In fact, if the intervals between the score lines are widened, it becomes difficult to tear along the score lines, and there is a problem in that ease of opening the lid conflicts with a decrease in the strength of the container itself.
本考案者は、この種の容器において、容器自体
の強度を低下することなく、容易に開封できるよ
うにすることについて種々研究した結果、蝶番部
の内側に、これに沿つて切裂用の細幅帯体を接着
剤にて貼着し、該切裂用細幅帯体を引つ張ること
により、蝶番部を切り裂くことを考えた。 As a result of various studies on how to make this type of container easier to open without reducing the strength of the container itself, the inventor of the present invention found that a cutting strip was installed along the inside of the hinge. The idea was to cut the hinge portion by attaching a wide band with an adhesive and pulling the narrow band for cutting.
しかし、このように蝶番部の内側に切裂用細幅
帯体を接着剤によつて貼着した場合には、以下に
述べるように蝶番部を、最後まで切り裂くことが
できない事態が発生するのであつた。 However, if the narrow strip for cutting is attached to the inside of the hinge part with adhesive, a situation will occur where the hinge part cannot be cut all the way, as described below. It was hot.
すなわち、切裂用細幅帯体の蝶番部に対する接
着力はその接着面積に比例し、この接着面積は切
裂用細幅帯体の長さに比例するものである。従つ

き不能部分を、手で引き裂くか、或いは、はさみ
等によつて切断しなければならないのであつた。 That is, the adhesion force of the narrow strip for tearing to the hinge portion is proportional to its adhesive area, and this adhesive area is proportional to the length of the narrow strip for tearing. Therefore, when tearing the hinge part by pulling this narrow strip for cutting, if there is no length of the uncut part at the initial stage of tearing, the narrow strip for cutting will be stretched. Since the adhesive area to the hinge part is wide and the adhesive force of the narrow strip for cutting to the hinge part is strong, the narrow strip for cutting can reliably tear the hinge part without coming off from the hinge part. As the tearing of the hinge progresses and the length of the part that has not yet been torn becomes shorter, the adhesive force to the hinge becomes smaller, so when the narrow strip for tearing is pulled, the length of the uncut part becomes shorter. In this case, the narrow strip for cutting peels off from the hinge part and ends up coming out of the hinge part, and the other end of the hinge part remains uncut.In other words, the other end of the hinge part There is a part that cannot be cut, and this part must be torn by hand or cut with scissors or the like.

For this reason, the present invention provides a container in which a pack body and a cover body made of a thin synthetic resin sheet are integrally molded via a bendable hinge part on one side. A narrow band for cutting coated with a pressure-sensitive adhesive is attached from the inside of the container along the hinge part, and one end of the narrow band for cutting is attached to one end of the hinge part. The gripping portion is configured to protrude from the container to the outside of the container, while the other end of the narrow strip for cutting is folded back and affixed to the outer surface of the container at the other end of the hinge portion. It is something.
