ABSTRACT:
The invention relates to a flexible packaging of parallelepipedal form for flexible, superposed flat elements, which may or may not be interlinked, forming a stack of axis XX, comprising a breakable zone (1) capable of constituting a dispensing opening that is initially closed and delimited by a line of weakening (2), said zone (1) extending over three faces (11, 12, 13) of the packaging. The breakable zone (1) is circular, or substantially circular, of diameter D, the greater part of the zone (1) is centred on one (11) of the faces of the packaging perpendicular to the stacking axis XX, and the other two parts of the breakable zone (1) being arranged on two faces (12, 13) of the packaging that are parallel to the axis XX of the stack.
