（産業上の利用分野）
本発明は、プラスチック製の容器本体のフランジ部厚を
測定するための容器本体のフランジ部厚測定装置に関す
る。DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a container body flange thickness measuring device for measuring the flange thickness of a plastic container body.
（従来の技術）
金属製の容器、例えば金属缶は種々の形態を有するもの
があるが、缶体の構造から３ピ一ス缶と２ピ一ス缶とに
区分することができ、る。３ピ一ス缶はブリキハンダ缶
とも言われ、円筒状胴部とふた及び底部を二重巻締めで
密封した構造である。(Prior Art) Metal containers, such as metal cans, have various shapes, but can be classified into three-piece cans and two-piece cans based on the structure of the can body. A three-piece can, also known as a tin solder can, has a cylindrical body, lid, and bottom sealed with double seams.
一方、２ピ一ス缶はブリキ打抜き缶とも言われ、胴部及
び底部（容器本体）を一体成形したものにふたを二重巻
締めする構造である。On the other hand, a two-piece can is also called a stamped tin can, and has a structure in which the body and bottom (container body) are integrally molded, and the lid is double-sealed.
これら金属缶は食品包装容器として各種食品缶詰、ジュ
ース、清涼飲料、ジャム類、乾燥食品等の容器に使用さ
れ、密封、保存機能が特に優れた剛性容器である。しか
しながら、金属缶には、下記のような改善すべき点があ
る。即ち、■ 金属缶であるために、軽量化に限界があ
る。These metal cans are used as food packaging containers for various canned foods, juices, soft drinks, jams, dried foods, etc., and are rigid containers with particularly excellent sealing and preservation functions. However, metal cans have the following points to be improved. That is, (1) Since it is a metal can, there is a limit to its weight reduction.
■ 衝撃を受けた時、−度つぶれると復元性がなく、変
形してしまう。■ If it is crushed by an impact, it will not recover and will be deformed.
■ プラスチック製容器に比べて、その製造上のエネル
ギーコストが高い。■ Compared to plastic containers, the energy cost of manufacturing them is higher.
■ 容器外装のディスブレス効果が金属の場合、自由に
変えることができず、外装手段は印刷によるしかない。■ If the container exterior is made of metal, it cannot be changed freely, and the only means of exterior packaging is printing.
■ 内容物を開缶せずに確認できるような透明容器をつ
くることは不可能である。■ It is impossible to create transparent containers that allow the contents to be checked without opening the can.
このような従来の金属缶における欠点を解決するため、
プラスチック製の容器本体に金属蓋を取付けてなる金属
蓋付容器が考えられる。In order to solve these drawbacks of conventional metal cans,
A container with a metal lid can be considered, which is a container made of plastic with a metal lid attached to the main body.
このようなプラスチック製の容器本体は、一般的な熱成
形法により容器形成に必要な厚みを有するプラスチック
シートを加熱し、金型を用いてフランジ部を有する容器
本体の成形品を成形し、続いてフランジ部の厚みを薄く
シ、さらにフランジ部の幅を所定の大きさとすることに
より得られる。Such a plastic container body is produced by heating a plastic sheet having the thickness necessary for forming the container using a general thermoforming method, molding the container body with a flange using a mold, and then This can be obtained by reducing the thickness of the flange portion and making the width of the flange portion a predetermined size.
また容器本体は、内部に内容物が収納され、その後フラ
ンジ部に金属蓋の周縁部が巻締められ゛Ｃ金属蓋付容器
が得られる。Further, the contents are stored inside the container body, and then the peripheral portion of the metal lid is wrapped around the flange portion to obtain a container with a metal lid.
（発明が解決しようとする課題）
上述のように、内容物が収納されたプラスチック性の容
器本体のフランジ部に、金属蓋の周縁部が巻締められ金
属蓋付容器が得られる。(Problems to be Solved by the Invention) As described above, the peripheral edge of the metal lid is wound around the flange portion of the plastic container main body in which the contents are stored, thereby obtaining a container with a metal lid.
ところで、フランジ部と周縁部との間で適切な巻締め作
業を行うためには、とりわけ容器本体のフランジ部の厚
さが所定の大きさであることが必要である。すなわち、
フランジ部の厚さが大きすぎると、フランジ部が十分折
曲がらず巻締め作業に適さない。またフランジ部の厚さ
が小さすぎると、十分な巻締め強度が得られず金属蓋の
周縁部との密着性が低下する。Incidentally, in order to perform an appropriate seaming operation between the flange portion and the peripheral edge portion, it is particularly necessary that the flange portion of the container body has a predetermined thickness. That is,
If the thickness of the flange part is too large, the flange part cannot be bent sufficiently and is not suitable for seaming work. Furthermore, if the thickness of the flange portion is too small, sufficient seaming strength will not be obtained and the adhesion to the peripheral edge of the metal lid will deteriorate.
本発明はこのような点を考慮してなされたものであり、
プラスチック性容器のフランジ部の厚さが所定の大きさ
になっているか否かを正確かつ迅速に測定することがで
きる容器本体のフランジ部厚測定装置を提供することを
目的とする。The present invention has been made in consideration of these points,
It is an object of the present invention to provide a flange thickness measuring device for a container body that can accurately and quickly measure whether the thickness of the flange portion of a plastic container is a predetermined thickness.
