摘要： A can top end includes a disc-shaped panel having a disc-shaped flat section an outer periphery to be engaged with an upper end of a can body, and a stay-on type tab attached on the flat section of the panel. The disk-shaped flat section has a primary score to define a primary scored portion surrounded by the primary score and the flat section further includes a secondary score to define a secondary scored portion surrounded by the secondary score. The tab has a connecting portion rotatably connected to a center portion of the flat section around an axis perpendicular to the flat section and the tab has both a pull-up end and a push-down end. The primary scored portion is located below the push-down end of the tab to enable the primary scored portion to be opened by pulling up the pull-up end of the tab. The secondary scored portion is located at a position facing the push-down end of the tab when the tab is rotated to a predetermined angle from an initial position, so that the secondary scored portion is opened by pulling up the pull-up end of the tab.

摘要翻译： 罐顶端包括具有圆盘状平坦部分的盘状面板，与罐体的上端接合的外周，以及附着在面板的平坦部分上的止动型接头。 盘形平坦部分具有初级分数，以定义由主要分数包围的主要刻痕部分，并且平坦部分还包括用于限定由次要分数包围的次级分数部分的次要分数。 突片具有连接部分，该连接部分围绕垂直于平坦部分的轴线可旋转地连接到平坦部分的中心部分，并且突片具有上拉端和下推端。 主刻痕部分位于突片的下推端的下方，以便通过拉起突片的上拉端来打开主刻痕部分。 当突片从初始位置旋转到预定角度时，次级刻痕部位于面向突片的下推端的位置，从而通过向上拉起第二刻痕部分的上拉端来打开二次刻痕部分 标签。
