Claims

[Claims for Utility Model Registration] 1. A container lid in which a score line for opening a part of the panel surface is formed, and a tension piece for opening is provided on a rivet formed on the panel surface within the score line, The score line is connected to a substantially arc-shaped first score line along the outer periphery of the rivet on the tip side of the tension piece, and the starting end is connected to approximately the center of the first score line, and the score line extends further from the tip of the tension piece. a second score line whose end reaches near the periphery of the panel surface; and a second score line whose respective starting ends are connected to the extreme ends of the second score line, which extend in opposite directions from the respective starting ends and are bent along the periphery of the panel surface. and a third and fourth score line extending along the outer side edge of the tension piece through the bent portion facing outward of the side edge of the tension piece, and each end thereof reaching near the end of the first score line; A discontinuous portion of the score line is formed between the end of the first score line and each end of the third and fourth score line, and each of the both side edges of the tension piece is connected to the score line. An easy-open container lid, characterized in that the lid is disposed between the discontinuous portions and at least two thirds of the distance outward from the end of the first score line of the discontinuous portions. 2. A protrusion projecting upward on one of the panel surfaces surrounded by the second score line and the third score line or the panel surface surrounded by the second score line and the fourth score line. The easy-open container lid according to claim 1, which is characterized by comprising: 3. A recess that sinks downward into one of the panel surfaces surrounded by the second score line and the third score line or the panel surface surrounded by the second score line and the fourth score line. The easy-open container lid according to claim 1, which is characterized by comprising: 4. The easy-open container lid according to item 1, wherein the tip of the tension piece has a bifurcated portion. 5. The easy-open container lid according to claim 1, wherein the tension piece has a bifurcated portion having different lengths at its distal end.
