Abstract

2.1 Hinge-lid packs made of thin cardboard and consisting of a pack part (12) and hinge-lid (13) present certain difficulties in gaining access to the closely packed cigarettes when the pack is to be used, even after a flap (30) as part of an inner blank (18) has been pulled off. 2.2 To make it easier to extract cigarettes, part of the inner blank (18), particularly its front wall (20), is lifted by being pulled upwards, so that a row (front row 34) of cigarettes (10) is likewise lifted relative to the remaining ones. It thus becomes easier to extract them. To make it easier to lift the front wall (20), a gripping tab (42) of the front wall (20) is exposed when the flap (30) is pulled off.
