Abstract: A rupture valve is formed on a wall of a container and has a break line along which a wall thickness of the rupture valve is decreased. The break line has an outer edge line which defines an outer edge of an opening region and a plurality of division lines which divide the opening region. The outer edge line has: a first base line and a second base line formed discontinuously such that the first base line and the second base line extend in a first direction, and are formed in a spaced-apart manner in a second direction orthogonal to the first direction; a first support portion forming line formed on a breaking portion of the first base line and extending from the first base line toward the second base line; and a second support portion forming line formed on a breaking portion of the second base line.
