摘要： An easy-open container includes a container barrel having an open end and a container end including a panel, a peripheral wall joined to and depending from a peripheral edge of the panel, and a pull tab joined to a lower edge of the peripheral wall. The peripheral wall is scored to provide a tear-off line joined to a side edge of the pull tab. The peripheral wall is fitted over the open end of the container barrel. An outer surface of the open end of the container barrel and an inner surface of the peripheral wall of the container end are bonded to each other through a bonded region. The tear-off line comprises a first continuous portion extending from the side edge of the pull tab through a bonded region of the peripheral wall above the pull tab into a non-bonded region of the peripheral wall above an upper edge of the bonded region, a second dotted-line portion joined to the first continuous portion and extending along the non-bonded region of the peripheral wall above the upper edge of the bonded region, and a third continuous portion joined to the second dotted-line portion and extending along the non-bonded region of the peripheral wall above the upper edge of the bonded region.
