    • An easy-to-open and optionally resealable beverage can end provides opening by pressing downward. An actuator lies flat initially to conform to stackability requirements, but is readily repositionable to a ready-to-open state.In the ready-to-open state a planer surface of the actuator or tab is at a substantial angle to the can's top. A rigid body is interposed between it and the can's tear panel. The actuator is secured to the can top. Downward force ruptures the tear panel, opening the can.Using a wide actuator, a shallow protrusion on the actuator enables gas-tight resealability of a can opening. The shallow protrusion has an interrupted helix and fits into the can opening. Providing tab attachment via a radiused slot allows the small degree of rotational movement needed for the helix to be turned and pull the actuator bottom sealingly abutted proximate to the perimeter of the opened area.
    • 易于打开且可选择地重新密封的饮料罐端部通过向下按压而提供开口。 致动器最初平坦地平放以符合堆叠性要求,但是容易重新定位成即将开启的状态。 在即将开启状态下,执行器或突片的平面与罐顶部成大致的角度。 刚体在其与容器的撕裂面板之间插入。 致动器固定到罐顶。 向下的力破裂撕裂面板,打开罐子。 使用宽致动器,致动器上的浅突起使得罐头开口的气密性可重新密封。 浅突起具有中断的螺旋并适合于罐头开口。 通过圆角槽提供突片附件允许旋转螺旋所需的小程度的旋转运动并且拉动致动器底部密封地抵靠开口区域的周边。
