本考案は、スコア線を破断することによつてパ
ネル面を全面開封するイージーオープン容器蓋に
関する。[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an easy-open container lid whose entire panel surface is opened by breaking the score line.
（従来の技術）
従来、この種の容器蓋ａにあつては、第６図示
のようにパネル面ｂの全外周縁に沿つて形成した
円形状のスコア線ｃを備え、スコア線ｃ内のパネ
ル面ｂに設けたリベツトｄに固着した引張片ｅを
引張することによりスコア線ｃを破断させてパネ
ル面ｂを全面開封するものは知られている。(Prior Art) Conventionally, this type of container lid a has a circular score line c formed along the entire outer periphery of the panel surface b as shown in FIG. A device is known in which the score line c is broken by pulling a tension piece e fixed to a rivet d provided on the panel surface b, and the entire panel surface b is opened.

ある。従つて引張片ｅの引張力の強さを調節しな
ければ安定した開封性が得られないという不都合
がある。 However, with such a configuration, when breaking along the score line c to open the panel surface b, the initial break first occurs on the action center line g passing through the tip f of the tension piece e, and then the panel surface gradually breaks. Since the breaking is carried out along the score line c toward both ends h of b, the breakage does not progress just by pulling the tension piece e upward and then lightly pulling it toward you. This requires an even stronger tensile force following the initial rupture. Further, a large tensile force is required until the breakage reaches both sides h of the panel surface b, but after passing the both sides h, even if the tensile force is gradually weakened, the breakage is sufficiently performed.
However, if the tensile force is not weakened from the middle and the tensile force is strong from the beginning and the score line c is broken all at once, the breakage will occur gradually until reaching both sides h of the panel surface b.
The latter half of the fracture, which passes through the subsequent side portions h, occurs quickly. Therefore, when opening the container lid a attached to the container, the container is gripped with a force corresponding to the tensile force required to unseal the panel surface b, so the hand gripping the container ends when the score line c is broken. The force may cause the container to shake along with your hand. At that time, the panel surface b separated from the container may come into contact with the shaking hand, and in that case, the hand may be injured. There is also the problem that the contents inside the container may spill out due to the container shaking. Therefore, there is an inconvenience that stable unsealability cannot be obtained unless the strength of the tensile force of the tension piece e is adjusted.

To provide an easy-to-open container lid that does not cause any risk of injury to the hand due to a separated panel surface when the lid is opened, and also prevents the contents inside the container from flying out.

とが出来る。 With the above structure, when used as a lid for a container, when the knob 5a of the tension piece 5 is grabbed and pulled upward as shown in the third figure, the tip 5c of the tension piece 5 is located on the action center line S. A part of the inner score line 3a that is in contact with is broken, and then an inner score line 3a is formed in the center of the panel surface 2, and an outer score line 3b is connected to the end 3c of the inner score line 3a. When the first open part 7 of the panel surface 2 surrounded by both score lines 3a and 3b is opened by breaking the first open part 7 of the panel surface 2, and in that state it is reversed at the connecting part 6 of the panel surface 2 and the tension piece 5 is further pulled, the connecting part 6 The extreme end 3d connected to the neighboring outer circumference score line 3b and the following inner circumference score line 3a
The remaining outer circumferential score line 3b leading to is broken and the second open portion 8 of the panel surface 2 surrounded by both score lines 3a and 3b is opened. Therefore, the inner score line 3a following the first break and the outer score line 3b following this
Since the breakage occurs at a position not far from the action center line s, the pulling force required to pull the tension piece 5 can be small, and the score line 3 can be maintained without adjusting the strength of the pulling force as the opening progresses. Breaking can be done reliably and easily, and stable opening can be achieved, so there is no shaking of the hand when gripping the bag. As a result, there is no risk of the panel surface 2 separated from the container coming into contact with the hand holding the container, so injury from the panel surface 2 can be prevented, and since the container does not shake, the contents inside the container can be prevented from flying out. I can do it.

用意な破断を防止することができる。 In addition, since the extreme end 3d of the outer circumferential score line 3b is bent and connected to the inner circumferential score line 3a from the outer circumferential edge side, the first break of the score line 3 due to pulling of the tension piece 5 is approximately ∩-shaped inner circumferential score line 3a. It is possible to prevent inadvertent breakage of the extreme end 3d of the outer circumferential score line 3b.

A folded portion 11 having a bent shape was formed. With such a configuration, it is possible to smoothly open the package along the folded part 11 by reversing the first open part 7 to the second open part 8 at the connecting part 6 of the panel surface 2, and also to It is possible to prevent the connecting portion 6 of No. 2 from being accidentally torn off.

ジーオープン容器蓋を提供するの効果がある。(Effect of the invention) As described above, according to the invention, the score line is bent from the center of the panel surface to the outer periphery of the panel surface, and then the score line is formed into an approximately ∩-shaped inner score line that runs along the panel surface and the outer periphery. , which is connected to the end of the inner score line on the outer circumferential edge side of the panel surface, has a substantially circular shape along the circumferential direction of the outer circumferential edge of the panel surface, and is bent at the very end so as to connect to the inner circumferential score line on the outer circumferential edge side. Since the tensile piece is fixed to the rivet placed inside the inner score line, it is possible to open the entire panel without breaking the score line from the inner score line to the outer score line. This is done by following the instructions. Therefore, since the inner score line that follows the first break caused by pulling the tension piece and the outer score line that follows this break occur at a position that is not far from the center line of action, the force that pulls the tension piece is small. It is possible to break the score line reliably and easily without adjusting the strength of the pulling force as the opening progresses, and has stable opening performance, which makes it easy to grip the container. To provide an easy-to-open container lid that can be opened without shaking hands, thereby preventing injury to the hands after opening, and preventing contents from spilling out because the lid does not shake.
