蓋を提供することにある。The present invention has been made in view of the above circumstances, and its purpose is to make it easy to insert a finger between the lifting part of the tab and the panel surface of the can lid body when opening a can, and to provide a constant To provide a can lid which can be opened easily and smoothly without the need for a large force because the action point of the tab does not come into contact with the score part while lifting the lifting part to an angle. .
上記目的を達成するために、本発明の缶蓋は、閉缶状態
において、タブの持ち上げ部と缶蓋本体との間に所定の
間隔が設定されると共に、上記タブの、スコア部を押し
下げる作用点部と上記缶蓋本体との間に所要の間隔が設
定されたものである。In order to achieve the above object, the can lid of the present invention has a predetermined distance between the lifting part of the tab and the main body of the can lid when the can is closed, and an action of pressing down the score part of the tab. A required distance is set between the dot part and the can lid body.

た後に、タブの作用点部が缶蓋本体のスコア部に接触し
て円滑にスコア部を下方に押し下げる。In the can lid of the present invention, the predetermined interval set between the lifting part of the tab and the can lid main body makes it easy to insert a finger into the interval when opening the can, and the tab's Due to the required spacing set between the point of action that pushes down the score part and the can lid body, the point of action of the tab and the can lid body do not come into contact until the tab is lifted at a certain angle. After the tab can be lifted with a small force and the tab can be firmly grasped with fingers, the action point of the tab contacts the score section of the can lid body and smoothly moves the score section downward. Press down.
以下、第１図と第２図に基づいて本発明の一実施例を説
明する。これらの図は、第３図の缶蓋の平面図において
中心線Ｑに沿って切断した場合の断面図を示している。Hereinafter, one embodiment of the present invention will be described based on FIGS. 1 and 2. These figures show cross-sectional views taken along the center line Q in the plan view of the can lid in FIG. 3.
また、第４図に示す上記従来例と同様の構成の部分につ
いては同符号を付して説明を省略する。Further, the same reference numerals are given to the parts having the same structure as those of the conventional example shown in FIG. 4, and the explanation thereof will be omitted.

下面６．＆が上方に傾斜して先細状に形成されている。In this embodiment, as shown in FIG. 1, a predetermined distance e is set between the tab 3 and the panel surface 4, and the lifting portion 6 of the tab 3 increases outwardly. Its lower surface 6. & is formed in an upwardly tapered shape.
また、タブ３の作用点部７の上面とパネル面４との間に
は所要の間隔Ｃ７が設定されていると共に、上記作用点
部７は、外方に行くほどその下面７ａが上方に傾斜して
先細状に形成されている。Further, a required interval C7 is set between the upper surface of the point of action portion 7 of the tab 3 and the panel surface 4, and the lower surface 7a of the point of action portion 7 is inclined upward as it goes outward. It is formed into a tapered shape.
なお、上記間隔Ｑ１は、１．Ｑｉｕ＋〜３．０度賃に設

。Note that the above interval Q1 is 1. It is preferable to set the rate at Qiu+ to 3.0 degrees. Because the interval Q1 is 1.011
If it is smaller than M, insert your finger f and 30
If it is larger than xx, a problem arises in that the lifting portion 6 is likely to be caught during handling during transportation.
また、上記間隔りは、２．Ｑｘｚ〜３，５！鱈こ設定す

しないという問題が生じる。Moreover, the above-mentioned interval is 2. Qxz~3,5! It is preferable to use codfish. This is because if the distance Q is smaller than 20cm, there will be a problem that the point of action 7 will come into contact with the panel surface 4 before the tab 3 is sufficiently lifted, and if it is larger than 3.5zx, the tab Even if the can is lifted sufficiently, the point of action 7 does not come into contact with the panel surface 4 and the can cannot be opened smoothly.

易に開缶させることができる。In the can lid configured as described above, the lifting portion 6 of the tab 3 is lifted, and the point of action 7 of the tab 3 is connected to the score portion 8.
When opening a can by pushing down the tab 3, a predetermined distance Q1 is set between the tab 3 and the panel surface 4, and the lifting portion 6 of the tab 3 increases outwardly as the lower surface 6 of the tab 3 increases.
Since the finger a is tapered upwardly, the finger f
can be easily inserted between the lifting part 6 of the tab 3 and the panel surface 4 (and the lifting part 6 can be easily lifted).
A required distance is set between the upper surface of the point of action section 7 and the panel surface 4, and the point of action section 7 is arranged outwardly (the lower surface 7a of the edge is inclined upward to form a tapered shape). As shown in FIG. 2, until the panel surface 4 of the score section 8 comes into contact with the point of action section 7 (until the tab 3 is lifted at a certain angle), a light force is applied. In addition to being able to lift the tab 3 upwards with the touch button, the tab 3 stands up to some extent after making contact, making it easy to apply force to the finger f.
By applying sufficient force to the tab 3 in a short period of time, the score portion 8 can be pushed down smoothly and reliably, and the can can be opened easily.

容易に行うことができる。As explained above, the can lid of the present invention has a predetermined distance between the lifting part of the tab and the main body of the can lid when the can is closed, and an action point of the tab that pushes down the score part. Since the required interval is set between the can lid body and the can lid body, the predetermined interval set between the lifting part of the tab and the can lid body allows the lid to fall within the above interval when the can is opened. In addition to being easy to insert your finger into, the required spacing between the point of action of the tab that pushes down the score section and the can lid body allows the point of action of the tab to remain until the tab is lifted at a certain angle. Since there is no contact between the part and the can lid body, it is possible to lift the tab with a small force, and after the tab can be firmly grasped with fingers, the point of action of the tab is attached to the can lid body. By contacting the scoring section and smoothly pushing the score section downward, the can opening operation can be easily performed.
