【考案の詳細な説明】
本考案は石油鑵、塗料罐、飲料鑵等の離日の改良に関す
るものである。[Detailed description of the invention] The present invention relates to the improvement of oil irons, paint cans, drinking irons, etc.
従来のこの種離日を説明すると、第２図に示す如く罐天
板１の一部に垂直な開口立上部１ａを有し、この開口立
上部１ａの上端部から外側下方へ更に内方へ延びる外側
曲げ部１ｂを有するものである。To explain this kind of conventional separation, as shown in Fig. 2, a part of the can top plate 1 has a vertical opening standing upper part 1a, and from the upper end of this opening standing upper part 1a, the opening is outwardly downward and further inward. It has an extending outer bent portion 1b.
この離日の製造方法、まず第１図に示す如く罐天板１に
開口２を有する垂直な立上相当部１ａ′を成形し、しか
る後該立上相当部１ａ’の上部を第２図に示す如く上端
を外方から下方へ更に内方へ弧状に曲げ成形して外側曲
げ部１ｂを設け、離日を構成している。In this manufacturing method, first, a vertical upright portion 1a' having an opening 2 is formed on a can top plate 1 as shown in FIG. As shown in the figure, the upper end is bent in an arc shape from the outside downward and further inward to form an outer bent portion 1b, thereby forming a departure part.
しかし、かかる離日においては外側曲げ部１ｂの先端が
遊端であるため、外側曲げ部１ｂが容易に変形してしま
うものであった。However, in such a departure, the outer bent portion 1b is easily deformed because the tip of the outer bent portion 1b is a free end.
このため、キャップ等を嵌着した際に十分な気温保持が
できないという重大な欠点を有している。For this reason, it has a serious drawback in that it cannot maintain sufficient temperature when a cap or the like is fitted.
本考案はかかる点に基いてなされたものである。The present invention has been made based on this point.
即ち、罐天板３の一部に開口立上部３ａを有し、この開
口立上部３ａの上端部から外側下方へ更に内方へ延びる
外側曲げ部３ｄを有する離日において、前記開口立上部
３ａの根本部より上端部の径をかなり小さくシ、前記外
側曲げ部３ｄの先端部を前記開口立上部３ａの根本部側
に当接させたことにより上記欠点を改良せんとしたもの
である。That is, when leaving Japan, a part of the can top plate 3 has an opening upright part 3a, and an outer bent part 3d extends outward downward and further inward from the upper end of this opening upright part 3a. This is an attempt to improve the above-mentioned drawbacks by making the diameter of the upper end portion of the opening considerably smaller than that of the root portion, and by bringing the tip of the outer bent portion 3d into contact with the root portion side of the opening upright portion 3a.
以下本考案の詳細を第３図〜第５図に示す一実施例によ
り説明する。The details of the present invention will be explained below with reference to an embodiment shown in FIGS. 3 to 5.
本考案の離日は第５図に示す如く罐天板３の一部に根本
部より上端部の径がかなり小さい開口立上部３ａを有し
、この開口立上部３ａの上端部から外側下方へ更に内方
へ延び、且つその先端部で前記開口立上部３ａの根本側
に当接する外側曲げ部３ｄを有している。As shown in Fig. 5, the device of the present invention has an open upright part 3a on a part of the can top plate 3, the diameter of which is considerably smaller at the upper end than the base, and extends downward outward from the upper end of this open upright part 3a. It further has an outer bent portion 3d that extends inward and abuts the base side of the opening upright portion 3a at its tip.
この離日の製造方法は、まず第３図に示す如く罐天板３
に開口４を有する開口立上相当部３ａ’を成形する。This manufacturing method first begins with the can top plate 3 as shown in Figure 3.
An opening equivalent portion 3a' having an opening 4 is formed at the opening.
この開口立上相当部３ａ’は根本部の外径が大きく、上
部が小径で垂直になっている。The opening equivalent portion 3a' has a large outer diameter at the base and a small diameter at the top, which is vertical.
この立上相当部３ａ’の上端から外巻きの小さな円弧部
３Ｃを第４図の如く形成する。From the upper end of this rising portion 3a', a small circular arc portion 3C is formed as shown in FIG. 4.
しかる後、該立上相当部３ａ’の上部を第５図の如く外
側から下方へ更に内方へ曲げ成形して外側曲げ部３ｄを
設け、その先端部を完成した開口立上部３ａの根本部側
に当接して離日を構成している。Thereafter, as shown in FIG. 5, the upper part of the rising portion 3a' is bent from the outside downward and further inward to form an outer bent portion 3d. Contact with the side constitutes departure.
かかる離日によれば、外側曲げ部３ｄの先端部が開口立
上部３ａの根本側に当接しているので、この外側曲げ部
３ｄに衝撃等が加って変形することがなくなり、キャッ
プ等を嵌着した際に十分な気密を保持することができる
。According to such departure, since the tip of the outer bent portion 3d is in contact with the root side of the opening upright portion 3a, the outer bent portion 3d is not deformed by impact or the like, and the cap etc. Sufficient airtightness can be maintained when fitted.
この場合、開日立上部３ａは根本部より上端部の径をか
なり小さくしであるので、従来のように垂直になったも
のに比較して罐天板の材料変形量が少なく、且つ外側曲
げ部３ｄの先端部はあまり大きく変形させなくても根本
部側に当接することができる。In this case, since the open Hitachi upper part 3a has a diameter considerably smaller at the upper end than at the base, the amount of material deformation of the can top plate is smaller compared to the conventional vertical one, and the outer bent part The tip portion 3d can come into contact with the root portion side without being deformed too much.
従って、離日の成形が著しく容易にできる。Therefore, the molding process can be done extremely easily.
尚、本実施例によれば立上部３ｄの先端に予め円弧部３
Ｃを形成したので、更に強い離日を製作できる。According to this embodiment, the arcuate portion 3 is formed in advance at the tip of the rising portion 3d.
Since we have formed C, we can create an even stronger departure from Japan.
