  • the tension applied when the outer film is shrunk during the manufacturing process tends to decrease near the ridges (edges) of the package, and the decreased tension in combination with the steps formed as a result of the texturing may cause creases to occur in the outer film.
  • the creases formed in the outer film is less likely to be noticeable particularly in the central region of each panel constituting the package, but is likely to be noticeable near the corners (ridges) formed as a result of coupling the panels to each other.
  • the creases formed in the outer film may more likely to become noticeable as the steps between the textured sections formed in the outer surface of the tobacco package (blank) and the surrounding regions become larger. If the textured sections in the outer surface of the tobacco package (blank) are protruding sections, such as embossed sections or protruding varnished sections, the pressure from the shrunk outer film acts on the protruding sections.
  • the textured sections in the outer surface of the tobacco package are recessed sections, such as debossed sections or debossed recesses, the pressure from the shrunk outer film acts on the regions surrounding the recessed sections.
  • the blank 10 having the above-described configuration is assembled into a box shape so that the package 1 is formed.
  • creases formed in the outer film 4 are less likely to be noticeable. More specifically, in the package 1, creases tend to occur due to the texture in the outer surfaces 100A at the ridges (edges) EG formed at the boundaries where the outer panels 100 oriented in different directions are connected to each other.
  • the near-ridge textured sections 5A and 5B do not extend continuously from the ridges EG after the package 1 is assembled, so that the near-ridge textured sections 5A and 5B can be disposed away from the ridges EG. Accordingly, creases occurring in the outer film 4 due to the steps between the near-ridge textured sections 5A and 5B and the surrounding regions 7 can be made less noticeable. As a result, the external appearance quality of the package 1 can be enhanced.
  • the nearest-to-ridge area NP of each of the near-ridge textured sections 5A and 5B is located away from the corresponding ridge EG (i.e., the ridge forming section EP of the blank 10) of the package 1 in the assembled state by 0.5 mm or larger, so that creases occurring due to the step between the ridge forming section EP and the surrounding region 7 can be made less noticeable.
  • the near-ridge textured sections 5A and 5B formed in the textured outer panels 110 of the blank 10 be separated from the ridge forming sections EP by a minimum separation dimension of 2 mm or larger.

  • the textured outer panels 110 are debossed (die-stamped) so that the near-ridge textured sections 5 (5A and 5B) are formed as debossed sections in which the outer surfaces 100A are recessed relative to the surrounding regions.
  • the near-ridge textured sections 5 5A and 5B
  • the near-ridge textured sections 5 (5A and 5B) formed as debossed sections have a recessed shape at the outer surface 100A side and a protruding shape at the inner surface 100B side.
  • the textured outer panels 110 are debossed from the outer surface 100A side so that the near-ridge textured sections 5 (5A and 5B) are formed as debossed recesses in which the outer surfaces 100A are recessed relative to the surrounding regions.
  • the debossed recesses can be formed by, for example, sandwiching and pressing the textured outer panels 110 between a protruding plate disposed at the outer surface 100A side of the textured outer panels 110 and a flat plate disposed at the inner surface 100B side.
  • the near-ridge textured sections 5 (5A and 5B) formed as debossed recesses are recessed at the outer surface 100A side and are flat at the inner surface 100B side. Specifically, the inner surfaces 100B of the textured outer panels 110 are flush with each other with no steps occurring between the near-ridge textured sections 5 (5A and 5B) and the surrounding regions 7.
  • the near-ridge textured sections 5 provided in the textured outer panels 110 of the blank 10 are recessed sections in which the outer surfaces 100A are recessed relative to the surrounding regions 7, a minimum separation dimension of 0.5 mm or larger is ensured between each near-ridge textured section 5 (recessed section) and the corresponding ridge forming section EP in this embodiment. Accordingly, after the package 1 is assembled, the near-ridge textured sections 5A and 5B are not disposed adjacent to the ridges EG of the package 1, so that creases occurring in the outer film 4 due to the texture of the near-ridge textured sections 5A and 5B can be made less noticeable. As a result, the external appearance quality of the package 1 can be enhanced.
  • the near-ridge textured sections 5A and 5B provided in the textured outer panels 110 of the blank 10 be separated from the ridge forming sections EP by a minimum separation dimension of 2 mm or larger from the standpoint of making creases in the outer film 4 less noticeable near the ridges EG of the package 1.
