Packs, in particular for cigarettes, and method and apparatus for producing said packs

A pack for cigarettes, comprising:

• an outer pack (12) configured as a hinge-lid box;
• an inner pack (13) configured as a sealed block (25) with an inner blank (26), the inner blank (26) configured to enclose a cigarette group (11) as pack contents, and which is made of aroma-tight and moisture-tight, thermally sealable sheet material, the inner pack (13) having a recloseable opening aid, in the region of an inner end wall (33), and folding flaps (75, 89, 108, 109, 110, 111) in the region of side walls of the inner pack (13), wherein;
• (a) a first set of the folding flaps (108, 109), in the region of an inner rear wall (34) of the inner blank (26), are connected to one another by thermal sealing outside of the cigarette group (11) pack contents, to form a fin seam (37);
• and
• (b) a second set of the folding flaps (110, 111), of the inner blank (26), are folded into an envelope, with the incorporation of a third set of the folding flaps as corner flaps (75, 89) of the inner blank (26), to form inner side walls (35) of the inner blank (26);
• and
• a covering made from material which is resistant to heat and compressive stress arranged within the sealed block (25) in the region of the inner side walls (35) and an inner front wall (32);
• wherein the fin seam (37) provided in the region of the inner rear wall (34) is not covered by the covering,
• wherein the second set of folding flaps (110, 111) and the corner flaps (75, 89) cover one another multiple times in layers proximal to the inner side walls (35) of the inner blank (26), and
• wherein the fin seam (37) is arranged at a spacing (A) of about 2.0 to 3.0 millimeters from where the second set of folding flaps (110, 111) and the corner flaps (75, 89) cover one another multiple times in layers, and
• wherein the second set of folding flaps (110, 111) and the corner flaps (75, 89) are connected to one another by thermal sealing, such that areas of overlap for the second set of folding flaps (110, 111) and the corner flaps (75, 89) are parallel to the plane of an inner side wall (35).
