mm), and its upper surface is fixed to the lower surface of the end plate 2, and the piercing edge is slightly protruded by a width above or to the outside of the arc-shaped portion 3a of the opening score, while the knob portion 5b is It has a shape and size that covers one side of the opening score. Further, the straight edge 7a is parallel to a bending guide rib (concave or convex) 9 provided linearly between both ends of the opening score 3. In the above, if the end plate 2 is made by coating the lower surface of the metal plate 2a with a heat-sealing resin (for example, low-density polyethylene with a Shore hardness of about 50) 2b, the latching protrusion (for example, a high-density polyethylene with a Shore hardness of about 60 or more) is coated. During molding (injection) of polyethylene) 8, the latching convex piece 8 and the end plate 2 are automatically heat-sealed.
前記摘み片５は、基端側を缶内突入部５ａと

まれる。 To open the can end plate 2 of the above embodiment, first lift the knob 5b of the knob 5 as shown by the arrow 13 in FIG. As shown in FIG. 4, the can-entering portion 5a enters the can and cuts off one side of the opening score. Then, when the knob 5b is pulled up diagonally as shown by the arrow 14 in FIG. 4, the cut piece 4 is reliably cut off as shown in FIG. When they come into contact with each other and are further pressed down in the direction of arrow 15 in FIG. 5, the cut pieces are folded as shown in FIG.
この折畳に際し、摘み片５の寸法を端板内へ収

片を取付孔に挿通し、その突出部を図示の型に加
熱加圧成型することもできる。 When folding, if the size of the knob 5 is set to fit within the end plate, it can be lowered below the periphery of the end plate, as shown in Figure 6, and there is no danger of it getting in the way. Note that the ribs 11, 11 are parallel to each other along the outside of the opening score, and reinforce the opening edge. The above-mentioned fixing of the knob piece can be done by embedding the attachment hole by injection molding, or by inserting the attachment piece into the attachment hole and molding the protrusion part under heat and pressure into the illustrated mold.
この実施例によれば、固定用の凸部７の一側を
直線縁７ａとしたので、切放片を整然と折畳する
ことができるが、直線縁７ａは必須要件ではな
い。また掛止凸片８を端板下面に固着したので、
スコア３を保護することができるが、固着する構
造は必須要件ではない。 According to this embodiment, since one side of the fixing convex portion 7 is formed with a straight edge 7a, the cut piece can be neatly folded, but the straight edge 7a is not an essential requirement. Also, since the latching convex piece 8 is fixed to the bottom surface of the end plate,
A score of 3 can be protected, but an anchoring structure is not a necessary requirement.
またこの実施例によれば支点用突起１０，１０

初期破断が容易であるが、斯る構成は必須要件で
はない。 Further, according to this embodiment, the fulcrum projections 10, 10
Since the projection 1 is provided in a protruding manner, the projection 1 can be opened by pulling up the knob using the projections 10, 10 as a fulcrum when opening.
0 and 10 act as the fulcrum of the screw, and
Although the initial breakage of the score is facilitated because the protrusions 10, 10 engage the non-openings of the end plates and prevent the fulcrum from falling into the can, such a configuration is not an essential requirement.
前記のようにして開口した後、再閉する必要が
生じた際には、切放片４を平面状に延ばして開口
部を閉鎖すると共に、掛止凸片８の先端を開口縁
部１６に掛止させる。この掛止により、剛性の無
い材質の端板であつても、切放片が浮上がるおそ
れなく、閉鎖状態を維持することができる。 After opening as described above, when it becomes necessary to reclose the opening, extend the cut piece 4 into a flat shape to close the opening, and at the same time, attach the tip of the latching convex piece 8 to the opening edge 16. make it hang. Due to this latching, even if the end plate is made of a non-rigid material, the closed state can be maintained without fear of the cut piece coming up.
尚、掛止凸片８はスコア３の全長に亘つてその
下側を覆うようにする場合もある。 Note that the latching convex piece 8 may be arranged to cover the lower side of the score 3 over its entire length.
又スコア３の形状は実施例の如く等幅の外、端
板の周縁から中心に向つて順次幅狭とする場合も
ある。 In addition, the shape of the score 3 may be of equal width as in the embodiment, or may be gradually narrower from the periphery of the end plate toward the center.
更に、摘み部５ｂで開口用スコアの一側を覆つ
た構造としたので摘み部５ｂに加わる外力は開口
用スコア３の内外で支持されることとなり、不慮
の外力によるスコアの破切を未然に防止すること
ができる。 Furthermore, since one side of the opening score is covered with the knob 5b, the external force applied to the knob 5b is supported inside and outside the opening score 3, thereby preventing the score from breaking due to an unexpected external force. It can be prevented.
（考案の効果）
この考案によれば、切放片の下面に掛止凸片を
設けたので、掛止凸片を開口縁部に掛止させるこ
とにより、再閉状態を維持することができる。(Effect of the invention) According to this invention, since the latching protrusion is provided on the lower surface of the cut piece, the re-closed state can be maintained by latching the latching protrusion on the opening edge. .
更に掛止凸片によつて開口用スコアの破切開始
部の下側が覆われ、該部が内容物によつて浸蝕さ
