AI Technical Summary
Technical Problem
The existing container lids with a synthetic resin gripping piece suffer from the risk of the scores breaking during attachment due to molding pressure, compromising the ease of opening.
Method used
The container lid design features a thick residual material thickness at the bottom of the scores and positions the upper end of the gripping piece extension near the score's upper end, ensuring the scores are strong during attachment but easily breakable during opening.
Benefits of technology
The design prevents score breakage during attachment while allowing easy opening by maintaining sufficient strength at the score's lower portion and ease of breakage at the remaining portions.

Abstract
To provide a novel container lid in which, when attached to the neck 100 of the container, each of the pair of scores 18a and 18b is difficult to break, yet when the neck 100 of the container is opened, each of the pair of scores 18a and 18b is easily broken. [Solution] The material residual thickness of the lower parts 18a-1x and 18b-1x of the first portions 18a-1 and 18b-1 of each of the pair of scores 18a and 18b is made relatively thick, and the upper ends of the lower parts 18a-1x and 18b-1x are positioned near the upper end of the extension portion 22 of the gripping piece 6.
