Abstract
An aroma-tight cigarette pack with an outer pack (12) configured in the form of a hinge-lid box, and also with an inner pack (11) configured in the form of a sealed block with an opening aid which can be used a number of times. The opening aid has a removal opening (51) which extends in a sub-region of an inner front wall (39) and of an adjacent inner end wall (41) and is covered over by a closure label (54) with an adhesively bonding connecting periphery (55). The inner pack (11) has closure seams (37) which are designed in the form of fin seams.
Claims15
A pack for cigarettes (10), comprising a dimensionally stable outer pack (12), in particular configured in the form a hinge-lid box, and also comprising an inner pack (11) configured in the form of a sealed block with an inner wrapper (14) made of preferably aroma-tight and moisture-tight, thermally sealable sheet material for wrapping a cigarette group (13) and having an inner collar (46) partially enclosing the cigarette group (13), wherein the sealed block, in the region of an end wall (41) and of an adjacent end region of a front wall (39), has a removal opening (51) with a closure label (54) which can be used a number of times, covers over the removal opening (51) in the closed position and is fixed on the sealed block (11) by adhesive bonding by way of an all-round connecting periphery (55), wherein:
- a) the inner wrapper (14) of the sealed block (11), in the region of an inner rear wall (40), has a continuous connecting seam (36) which extends over the entire width—transversely to the cigarettes—of the sealed block (11) and is configured in the form of a fin seam;
- b) continuous closure seams (37, 38) configured in the form of fin seams are arranged on two mutually opposite narrow block surfaces, that is to say on inner side walls (43, 44);
- and
- c) connecting flaps of the fin seams (36, 37, 38) are positioned against the respectively associated wall of the sealed block, as are triangular or trapezoidal projections (45) in the region of the closure seams (37, 38).
A method of producing packs for cigarettes (10), comprising an outer pack (12) configured in the form of a hinge-lid box, and also comprising an inner pack (11) configured in the form of a sealed block for accommodating a cigarette group (13) and having an inner collar (46) partially enclosing the cigarette group (13), wherein the inner pack (11) consists of a preferably aroma-tight and moisture-tight, thermally sealable sheet material which, in the region of an inner end wall (41) and of an adjacent end region of an inner front wall (39), has a removal opening (51) with a closure label (54) which can be used a number of times and covers over the removal opening (51) in the closed position, wherein:
- a) during wrapping of the cigarette group (13) in the longitudinal direction of the cigarettes, a continuous sheet-material web (35) in the width of a blank for the inner pack (11) is provided, in an off-center region, with punching lines (52) for an opening tab (53) of the inner pack (11) and with a closure label (54), which covers over the region of the punching line (52), and is then fed continuously to a sheet-material station (63);
- b) in the region of the sheet-material station (63), units made up of a cigarette group (13) and an inner collar (46) partially enclosing the same are fed one after the other, with the upper wall (47) directed upward, along a conveying path, wherein the cigarettes of the cigarette group (13) are oriented transversely to the conveying direction;
- c) the prepared sheet-material web (35) is positioned approximately centrally on the successive units (13/46), such that the removal opening (51) with opening tab (53), the opening being defined by the punching line (52), is located in the region of a recess (49) of the upper wall (47) of the inner collar (46);
- d) the sheet-material web (35) is folded around the successively transported pack units (13/46) to form a tubular wrapper, wherein peripheral strips of the sheet-material web (35) are brought together beneath the movement plane of the pack unit (13/46);
- e) in a first sealing station (64)—longitudinal sealing station (64)—, the peripheral strips of the sheet-material web (35) are connected to one another by thermal sealing to form a continuous fin seam, that is to say a connecting seam (36);
- f) the tubular sheet-material web (35) with the pack units (13/46) is then fed to a second sealing station, that is to say a transverse sealing station (66), in which, in the region between successive pack units (13/46), the layers of the sheet-material web (35) are connected to one another to form transversely directed closure seams (37, 38) and, at the same time, a central severing cut is executed between the closure seams (37, 38);
- g) at the same time or thereafter, the fins of the closure seams (37, 38) are folded over against the inner side walls (43, 44);
- h) in the region of a downstream collar station (70), blanks of the pack collars (17) of the outer pack (12) are fed transversely to the pack path (69) of the inner packs (11) and are positioned on the upper side of the same, to be precise outside the region of the closure label (54);
- i) then collar side walls (30) of the pack collar (17) are folded over against the inner side walls (43, 44);
- and
- j) finally, the finished inner pack (11) with pack collar (17) is pushed into a partially folded outer pack (12), which is open in the region of a lid (16), and said outer pack is then folded definitively.
The method as claimed in 12, wherein during transportation of the cigarette group (13) with inner collar (46) transversely to the conveying direction, following the production of the closure seams (37, 38) and severing of the inner packs (11) from the continuous sheet-material web (35), the inner pack (11) are advanced in the transverse direction—with the inner base wall (42) located at the front, as seen in the transporting direction—and in that then, during transversely directed transportation, the fins of the closure seams (37, 38) are folded over and, thereafter, are fixed in abutment against inner side walls (43, 44) by sealing.
