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.
■ 容器外装のデイスプレィ効果が金属の場合、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 display effect of 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ている。In order to solve these drawbacks of conventional metal cans,
Containers with metal lids are being considered, which are made by attaching a metal lid to a plastic container body.
また、プラスチック製の容器本体に金属蓋を取付ける場
合、容器本体のフランジ部に金属蓋の周縁部を巻締めて
取付けている。Furthermore, when a metal lid is attached to a plastic container body, the peripheral edge of the metal lid is wrapped around the flange portion of the container body.
容器本体のフランジ部に金属蓋の周縁部を巻締める場合
、次のように行なわれている。When wrapping the peripheral edge of a metal lid around the flange of a container body, it is done as follows.
すなわち、まずフランジ部を有するプラスチック製の容
器本体内に内容物を充填し、次に容器本体に周縁部を有
する金属蓋を装着し、その後容器本体のフランジ部に金
属蓋の周縁部を巻締めている。That is, first the contents are filled into a plastic container body having a flange, then a metal lid having a peripheral edge is attached to the container body, and then the peripheral edge of the metal lid is wrapped around the flange of the container body. ing.
このように巻締めることによって、金属蓋付容器の密閉
性を高め内容物を長期間保存することができる。By tightening the container in this way, the sealability of the container with a metal lid can be improved and the contents can be preserved for a long period of time.
（発明が解決しようとする課題）
上述のように、金属蓋付容器は容器本体のフランジ部に
金属蓋の周縁部を巻締めて構成されている。(Problems to be Solved by the Invention) As described above, a container with a metal lid is constructed by wrapping the peripheral edge of the metal lid around the flange portion of the container body.
また、巻締め作業は大気中で行なわれるため、当然金属
蓋付容器内には空気が混入する。Furthermore, since the seaming work is performed in the atmosphere, air naturally gets mixed into the container with a metal lid.
しかしながら、金属蓋付容器内部に混入する空気のうち
、とりわけ酸素は内容物の劣化を促進する。このため、
この酸素によつて金属蓋付容器の保存性が低下するとい
う問題がある。However, among the air mixed inside the container with a metal lid, oxygen in particular accelerates the deterioration of the contents. For this reason,
There is a problem in that this oxygen deteriorates the storage stability of containers with metal lids.
本発明はこのような点を考慮してなされたものであり、
内容物の保存性の向上を図ることができる金属蓋付容器
を提供することを目的とする。The present invention has been made in consideration of these points,
An object of the present invention is to provide a container with a metal lid that can improve the storage stability of contents.
（課題を解決するための手段）
本発明は、フランジ部を有するプラスチック製容器本体

を備えた金属蓋付容器であって、前記金属蓋の内面また
は容器本体内面に脱酸素剤を固着したことを特徴として
いる。(Means for Solving the Problems) The present invention provides a container with a metal lid, comprising a plastic container body having a flange portion, and a metal lid having a peripheral edge portion around which the flange portion is wound. It is characterized by having an oxygen absorber fixed to the inner surface of the container or the inner surface of the container body.
（作 用）
本発明によれば、金属蓋の内面または容器本体の内面に
固着された脱酸素剤によって、金属蓋付容器内部の酸素
濃度を低減することができる。(Function) According to the present invention, the oxygen concentration inside the container with a metal lid can be reduced by the oxygen absorber fixed to the inner surface of the metal lid or the inner surface of the container body.
（実施例）
以下、図面を参照して本発明の実施例について説明する
。(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.
第１図および第２図は、本発明による金属蓋付容器の一

底部を構成するシートブランクを金型に入れ、そのシー
トブランクに沿って射出用樹脂を射出して得ることもで
きる。For example, a container body can be obtained by thermoforming a polypropylene/ethylene vinyl alcohol copolymer/polypropylene laminate. Alternatively, it can also be obtained by placing a sheet blank constituting the trunk and bottom of the container body into a mold and injecting the injection resin along the sheet blank.
一方、金属Ｍ１１の内面略全域にはエポキシ系樹脂層と
、変性ポリオレフィン層との積層体（図示せず）が予め
コーチイブされている。On the other hand, a laminate (not shown) of an epoxy resin layer and a modified polyolefin layer is coated in advance on substantially the entire inner surface of the metal M11.
次に、金属蓋付容器の巻締め作業について説明する。Next, the seaming work of the container with a metal lid will be explained.
まず、プラスチック製容器本体１４内に内容物１６を充
填する。First, the contents 16 are filled into the plastic container body 14.
その後、容器本体１４に金属蓋１１が、フランジ部１５
に周縁部１２を重ね合わせた状態で装着される。Thereafter, the metal lid 11 is attached to the container body 14, and the flange portion 15
It is attached with the peripheral edge portion 12 superimposed on the holder.
続いて、第２図に示すように、容器本体１４と金属蓋１
１はリフタ２２によって持上げられ、上方に配置された
チャック２３との間で容器本体１４と金属蓋１１は上下
方向に押圧される。Next, as shown in FIG. 2, the container body 14 and the metal lid 1 are attached.
1 is lifted by a lifter 22, and the container body 14 and metal lid 11 are pressed in the vertical direction between them and a chuck 23 disposed above.
そして、このようにリフタ２２とチャック２３との間で
押圧された状態で、容器本体１４のフランジ部１５に金
属Ｍ１１の周縁部１２が複数の巻締ローラ２０によって
巻締められる。Then, while being pressed between the lifter 22 and the chuck 23 in this manner, the peripheral edge portion 12 of the metal M11 is wound around the flange portion 15 of the container body 14 by a plurality of seaming rollers 20.
続いて、巻締めを行なった金属蓋１１の周縁部１２を加
熱し、金属蓋１１の内面にコーティングされた変性ポリ
オレフィン層を溶融させ、そして金属蓋１１の周縁部１
２と容器本体１４のフランジ部１５とを完全に融着させ
て、金属蓋付容器１０を得る。Subsequently, the peripheral edge 12 of the metal lid 11 that has been seamed is heated to melt the modified polyolefin layer coated on the inner surface of the metal lid 11, and the peripheral edge 12 of the metal lid 11 is heated.
2 and the flange portion 15 of the container body 14 are completely fused to obtain a container 10 with a metal lid.
本実施例によれば、金属蓋１１の内面に脱酸素剤１８が
固着されているので、金属蓋付容器１０内部の酸素をこ
の脱酸素剤１８で確実に捕獲し、金属蓋付容器１０内の
酸素濃度を低下させることができる。このため内容物１
６の酸化を防止して保存性の向上を図ることができる。According to this embodiment, since the oxygen absorber 18 is fixed to the inner surface of the metal lid 11, the oxygen inside the metal lid container 10 is reliably captured by the oxygen absorber 18, and the oxygen inside the metal lid container 10 is can reduce the oxygen concentration of Therefore, contents 1
It is possible to prevent the oxidation of No. 6 and improve the storage stability.
例えば脱酸素剤１８として、エージレス（三菱ガス化学
の商品名）を用いた場合は、金属蓋付容器１０内の酸素
濃度を約０．１％以下まで低減させることができる。For example, when Ageless (trade name of Mitsubishi Gas Chemical) is used as the oxygen absorber 18, the oxygen concentration in the metal lidded container 10 can be reduced to about 0.1% or less.
なお、上記実施例において、脱酸素剤１８を金属Ｍ１１
の内面に固着した例を示したが、これに限らず、例えば
容器本体１４の内面、例えば底面または側面に固着して
も良い。In addition, in the above embodiment, the oxygen absorber 18 is made of metal M11.
Although an example is shown in which the container is fixed to the inner surface of the container body 14, the present invention is not limited thereto, and the container body 14 may be fixed to the inner surface of the container body 14, for example, the bottom surface or the side surface.
この場合は、内容物１６として粉体状のものを収納する
ことが好ましい。In this case, it is preferable to store powdered material as the content 16.
以上説明したように、本発明によれば、金属蓋の内面ま
たは容器本体の内面に固着された脱酸素剤によって、金
属蓋付容器内部の酸素濃度を低減することができる。こ
のため金属蓋付容器１０内に収納された内容物の酸化を
防止して、保存性の向上を図ることができる。As described above, according to the present invention, the oxygen concentration inside the container with a metal lid can be reduced by the oxygen absorber fixed to the inner surface of the metal lid or the inner surface of the container body. Therefore, oxidation of the contents stored in the container 10 with a metal lid can be prevented, and the storage stability can be improved.
