Abstract

A cuboidal cigarette pack of the hinge-lid-box type (10) is enclosed by an outer wrapper made of film. The latter has a tear-open thread (24) which extends obliquely or diagonally in the region of a front wall (14) and rear wall (15) and merges into side walls (16, 17) via arcuate regions. This allows optimum opening and removal of the outer wrapper with the aid of the tear-open thread (24).
