Definitions

  • the present invention relates to a tobacco package and a blank forming an outer wrapping body of the tobacco package.
  • a tobacco package that houses tobacco products is formed by intermediate wrapping paper with which the tobacco products are wrapped, and outer wrapping paper with which the intermediate wrapping paper is covered.
  • This kind of tobacco package is referred to as so-called individual packaging, and as the outer wrapping paper, outer wrapping paper that is formed of thin paper and is referred to as a so-called soft package, outer wrapping paper that is referred to as a so-called hard package and is formed by fabricating a paper board into a box shape, and the like are known (refer to Patent document 1, for example).
  • Document EP 0 615 701 discloses a paper forming a wrapping paper for a tobacco package, the wrapping paper comprising cellulose fibers being disrupted by aid of a sulphite method to create a certain degree of transparency.
  • Document JP 2006 056603 discloses a cigarette box with different coloured markings in different areas of the box.
  • Document JP S50 25048 discloses a method for producing transparent pattern paper made of synthetic fiber paper mainly composed of polyolefin fibers, wherein the volume ratio of polyolefin fibers lies in the range of 70 to 90% by volume.
  • the present invention is made in the light of the problem like this, and an object of the present invention is to provide an art for giving a visual effect to a tobacco package that houses tobacco products by a different method from the conventional method.
  • polyolefin fibers contained in a polyolefin fiber containing unit is transparentized by heating a specific region in the polyolefin fiber containing unit of an outer wrapping body in which a tobacco product is wrapped.
  • the tobacco package according to the present invention includes an outer wrapping body in which a tobacco product is wrapped, and a polyolefin fiber containing unit that composes at least a part of the outer wrapping body, and has a polyolefin fiber layer containing polyolefin fibers, wherein transparentizing treatment by heating is applied to a specific region in the polyolefin fiber containing unit.
  • the present invention can be also grasped as a blank that forms the outer wrapping body of a tobacco package.
  • the present invention is a blank that forms the outer wrapping body of a tobacco package in which a tobacco product is wrapped, includes a polyolefin fiber containing unit that composes at least a part of the blank, and has a polyolefin fiber layer containing polyolefin fibers, wherein transparentizing treatment by heating is applied to a specific region in the polyolefin fiber containing unit.
  • a feeling of transparency is given by the specific region (hereunder, also referred to as a "transparentization region") of the polyolefin fiber containing unit being heated, so that a different outer appearance from another region (hereunder, also referred to as a "non-transparentization region") to which the transparentizing treatment is not applied is given.
  • a visual effect can be given to the tobacco package by a different method from a conventional method.
  • feel and texture that are different from feel and texture of the conventional tobacco packages can be given.
  • the polyolefin fiber containing unit may have the polyolefin fiber layer on an outermost layer. According to this, a feeling of transparency can be more preferably given to the transparentization region of the polyolefin fiber containing unit. Further, in the transparentizing treatment, the specific region in the polyolefin fiber containing unit may be heated while being pressurized. According to this, the transparentizing treatment can be applied more efficiently. Further, the polyolefin fiber layer contains 5% by weight or more and 40% by weight or less of the polyolefin fibers. Thereby, it becomes possible to make it difficult to generate paper dust at the time of manufacturing the outer wrapping body, while visibility of transparentization in the specific region in which the outer wrapping body is heated is enhanced.
  • the polyolefin fiber layer may contain 15% by weight or more and 25% by weight or less of the polyolefin fibers. According to this, printability can be favorably ensured while it is made possible to see a color on an inner surface side of the outer wrapping body through from an outer side.
  • a recessed and raised design unit in which recessing and raising work is applied may be provided on an outer surface of the polyolefin fiber containing unit, and the specific region to which the transparentizing treatment is applied may be associated with the recessed and raised design unit.
  • an inner surface of the polyolefin fiber containing unit may have a different color from an outer surface of the polyolefin fiber containing unit.
  • the inner surface of the polyolefin fiber containing unit may be colored in ink of a different color from the outer surface. Further, on the inner surface of the polyolefin fiber containing unit, a sheet material having a different color from the outer surface may be pasted.
  • the outer wrapping body may be covered with a transparent film that seals the outer wrapping body, and at least a part of a non-transparentization region to which the transparentizing treatment is not applied in the polyolefin fiber containing unit may be vertically laid on a heat seal unit of the transparent film.
  • the heat seal unit is generally formed by melting the sealant that is coated on the inner surface of the transparent film by heating the end portions of the transparent film by superposing the end portions of the transparent film, and bonding the end portions of the transparent film to each other.
  • Sealing of the outer wrapping body is generally performed in a state in which a tobacco product is packed (housed) inside the outer wrapping body, and if in heating treatment at the time of forming the heat seal unit, a heating temperature becomes higher than a set temperature for some reason, or the heating temperature is continued for a longer time period than a set time period, it may affect quality of the tobacco product.
  • At least a part of the non-transparentization region in the polyolefin fiber containing unit is disposed to be vertically laid on the heat seal unit of the transparent film, whereby if transparentization of the polyolefin fiber layer (polyolefin fibers) is confirmed in the non-transparentization region, it may be judged that there is a possibility that heating at the time of forming the heat seal unit is not performed as set. That is, presence or absence of product abnormality can be inspected by using an outer appearance of the outer wrapping body, that is, presence or absence of transparentization of the non-transparentization region in the sealing process of the outer wrapping body.
  • a recessed and raised design unit in which recessing and raising work is applied to an outer surface may be provided in at least a part of a region where the non-transparentization region and the heat seal unit are vertically laid on each other, in the polyolefin fiber containing unit.
  • an inner surface in at least a part of a region where the non-transparentization region and the heat seal unit are vertically laid on each other may have a different color from an outer surface.

  • the content of the polyolefin fibers contained in the polyolefin fiber layer 71 is set in the range from 5 to 40% by weight, but by setting the content of the polyolefin fibers in the polyolefin fiber layer 71 at 5% by weight or more, consumers visually recognize transparentization of the transparentization regions R1 easily when the consumers see the outer wrapping body 4 of the tobacco package 1.
  • the content of the polyolefin fibers in the polyolefin fiber layer 71 is increased more, the transparency of the polyolefin fiber layer 71 by applying the transparentizing treatment is enhanced more, but when the content of the polyolefin fibers becomes excessively high, paper dust are easily generated at the time of manufacturing the blank 10, and there is concern that printing is adversely affected.
  • the polyolefin fiber layer 71 preferably contains 5% by weight or more and 40% by weight or less of polyolefin fibers.
  • the polyolefin fiber layer 71 it is especially preferable to set the content of the polyolefin fibers in the polyolefin fiber layer 71 at 15% by weight or more, in order to see the color on the back surface 10b in the blank 10 through from the outer surface 10a side. Further, in order to ensure printability in the blank 10 favorably, it is especially preferable to set the content of the polyolefin fibers in the polyolefin fiber layer 71 at 25% by weight or less. From the above, it can be said that the polyolefin fiber layer 71 especially preferably contains 15% by weight or more and 25% by weight or less of polyolefin fibers.
  • the transparentization regions of the blank 10, and the outer wrapping body 4 formed by the blank 10 are disposed in association with the recessed and raised design units 8.
  • the recessed and raised design that is given by the recessed and raised design units 8, and the regions in which the polyolefin fiber containing unit 7 is transparentized can be associated with each other.
  • the visual effect by contrast of the transparentization regions R1 and the non-transparentization regions R2 of the outer wrapping body 4 can be made far more remarkable.
  • reference symbol A is written in the recessed and raised design units 8 corresponding to the transparentization regions R1, of the plurality of recessed and raised design units 8 which are formed on the outer surface 4a (the front surface 10a) of the outer wrapping body 4 (the blank 10), and hereunder, the recessed and raised design units 8 corresponding to the transparentization regions R1 will be referred to as "transparentization recessed and raised design units 8A".
  • Reference symbol B is written in the recessed and raised design units 8 corresponding to the non-transparentization regions R2, of the plurality of recessed and raised design units 8, and hereunder, the recessed and raised design units 8 corresponding to the non-transparentization regions R2 will be referred to as "non-transparentization recessed and raised design units 8B"
  • hatching is applied to the transparentization recessed and raised design units 8A. Hatching is not applied to the non-transparentization recessed and raised design units 8B.
  • the non-transparentization recessed and raised design unit 8B and the transparentization recessed and raised design unit 8A are both given the recessed and raised design, but external appearances of both of them differ from each other in a point that the former (the non-transparentization recessed and raised design unit 8B) presents the same white color (the first color) as the non-transparentization region R2, whereas the latter (the transparentization recessed and raised design unit 8A) presents the pink color (the second color) similar to the inner surface (the back surface 10b).
  • the outer wrapping body 4 (the blank 10) according to the present embodiment, instead of all of the recessed and raised design units 8 which are provided at the plurality of spots, only some of the recessed and raised design units 8 are formed as the transparentization recessed and raised design units 8A, and the remaining recessed and raised design units 8 are formed as the non-transparentization recessed and raised design units 8B, whereby in the same recessed and raised design units 8, the outer appearances are caused to differ significantly. Thereby, the visual effect that is obtained by the transparentizing treatment to the polyolefin fiber containing unit 7 of the outer wrapping body 4 (the blank 10) can be made more remarkable.
  • the non-transparentization recessed and raised design units 8B to which the transparentizing treatment by heating is not applied are disposed on the side walls 23 of the housing body 2 and the side walls 33 of the lid body 3 in the outer wrapping body 4.
  • the heat seal units 51 of the transparent film 5 are disposed along the side walls 23 of the housing body 2 and the side walls 33 of the lid body 3.
  • at least some of the non-transparentization regions R2 to which transparentizing treatment is not applied, in the polyolefin fiber containing unit 7 in the outer wrapping body 4 are formed to be vertically laid on the heat seal units 51 of the transparent film 5.
  • the recessed and raised design units in which recessing and raising work is applied to the outer surface 4a are provided. That is, in the tobacco package 1, the heat seal units 51 of the transparent film 5 are disposed in positions where the heat seal units 51 are vertically laid on the non-transparentization recessed and raised design units 8B that are formed on the side walls 23 and 33 of the outer wrapping body 4.
  • the heat seal units 51 of the transparent film 5 are heated to a high temperature by a heat seal machine (not illustrated) for only a relatively short time period so that the sealant is melted and the end portions of the transparent film 5 are bonded to each other.
  • the melting temperature of the polyolefin fibers to be used, the heating temperature, the heating time period of the heat seal machine and the like are adjusted so that transparentization of the polyolefin fiber layer 71 in the non-transparentization regions R2 does not occur, within a range where heat seal by the heat seal machine is properly performed.
  • transparentization of the polyolefin fiber layer 71 in the non-transparentization regions R2 occurs at a time point at which heat seal by the heat seal machine is completed, that is, at a time point at which sealing of the outer wrapping body 4 by the transparent film 5 is completed, it means that unintentional transparentization has occurred.
  • unintentional transparentization like this can be determined based on the fact that the non-transparentization regions R2 (for example, the non-transparentization recessed and raised design units 8B) in the outer surface 4a do not present the white color (the first color), but presents the pink color (the second color), at a time point at which sealing of the outer wrapping body 4 by the transparent film 5 is completed, for example.
  • the non-transparentization regions R2 for example, the non-transparentization recessed and raised design units 8B
  • the outer wrapping body 4 has an advantage of being usable to assist in determination of production abnormality in the process of wrapping the tobacco products, in addition to an effect of being able to give a new visual effect by the method different from the conventional method.
  • the heat seal units 51 of the transparent film 5 are disposed in positions where the heat seal units 51 are vertically laid on the non-transparentization recessed and raised design units 8B of the outer wrapping body 4, and therefore, presence or absence of product abnormality can be easily determined based on whether or not transparentization occurs to the non-transparentization recessed and raised design units 8B.
  • the inner surface in at least some of the regions where the non-transparentization regions R2 of the outer wrapping body 4 and the heat seal units 51 are vertically laid on each other is colored in a different color from the outer surface, and therefore, presence or absence of product abnormality can be easily determined by confirming whether or not a spot where the color that is attached to the inner surface of the outer wrapping body 4 is seen through on the outer surface is present in the non-transparentization regions R2.
  • the outer wrapping body 4 (the blank 10) according to the present embodiment, the color which is different from the color on the outer surface 4a is given to the inner surface of the polyolefin fiber containing unit 7. According to this, the difference in the outer appearance between the transparentization region R1 to which transparentization occurs by the transparentizing treatment to the polyolefin fiber containing unit 7 and the non-transparentization region R2 can be made more remarkable, and consumers can recognize the difference far more easily.
  • the inner surface and the outer surface 4a relating to the polyolefin fiber containing unit 7 do not necessarily have to have different colors. In a case like this, the tobacco package 1 can produce a new visual effect based on the difference in outer appearance between the transparentization region R1 and the non-transparentization region R2, and power to appeal to the consumers can be enhanced.
  • the front surface 10a of the blank 10 is not colored in ink as described above, but the color different from the front surface 10a is given to the back surface 10b by coloring the back surface 10b in the different color from the color of the base paper, but the present invention is not limited to this.
  • the front surface 10a of the blank 10 may be colored in ink
  • the back surface 10b may be colored in a different color from the front surface 10a.
  • the back surface 10b of the blank 10 is a flat surface, but a level difference may be formed in a boundary portion between the recessed and raised design units 8 and surroundings of the recessed and raised design units 8.
  • the front surface 10a sides may be recessed as compared with the other regions, and the back surface 10b sides may be raised as compared with the other regions.
  • the front surface 10a sides may be raised as compared with the other regions, and the back surface 10b sides may be recessed as compared with the other regions.
  • the polyolefin fiber containing unit 7 of the blank 10 is composed as a monolayer structure, but may be composed as a multilayered structure by forming the front surface 10a side of the blank 10, which forms the outer surface 4a of the outer wrapping body 4, by the polyolefin fiber layer 71, and pasting another base paper, a film or the like on the polyolefin fiber layer 71.
  • the base paper or the like which is colored in a color different from the color of the polyolefin fiber layer 71 may be pasted on the polyolefin fiber layer 71.
  • the transparentization regions R1 are disposed in association with only the recessed and raised design units 8, but the present invention is not limited to this.
  • the transparentization regions R1 are set to the regions where the recessed and raised design units 8 are not provided, and transparentization of the polyolefin fiber layer 71 relating to the regions may be performed.
  • the case of performing the transparentizing treatment of the polyolefin fiber layer 71 by heating, by using heating device 200, the specific regions in the front surface 10a of the blank 10 where the recessed and raised design units 8 are formed is described as an example, but the present invention is not limited to this.
  • the polyolefin fiber layer 71 may be transparentized by directly heating the polyolefin fiber layer 71 of the blank 10 by an embossing die when the embossing die formed on a front surface of an embossing roll for forming the recessed and raised design units 8 contacts the front surface 10a of the blank 10, for example.
  • a step of forming the recessed and raised design units 8 on the front surface 10a of the blank 10 and a step of transparentizing the polyolefin fiber layer 71 in the transparentization regions R1 of the blank 10 can be performed in a same step, and therefore, the number of steps which are needed to manufacture the tobacco package 1 can be reduced. Further, when design is applied onto the front surface of a package by printing, and recessing and raising work is applied to be superposed on the design, there is a possibility of misalignment of the printed design and the recessing and raising work occurs.
  • the regions in which the pink (the second color) that is applied onto the back surface 10b seems to emerge on the front surface 10a and is seen by performing transparentization of the polyolefin fiber layer 71 are not out of the regions where the recessed and raised design units 8 are formed, and an advantage that misalignment of both of them can never occur is obtained.
  • Fig. 7 is a perspective view of the tobacco package 1 according to a modification example.
  • a contour a boundary line from the non-transparentization region R2 of the transparentization region R1 which is associated with the recessed and raised design unit 8 (the transparentization recessed and raised design unit 8A) matches an outline of the recessed and raised design unit 8 (the transparentization recessed and raised design unit 8A), but the present invention is not limited to this. That is, as the modification example illustrated in Fig.
  • positions of the outline of the transparentization region R1 and the outline of the recessed and raised design unit 8 may be misaligned, and a mode like this also falls in category in which the transparentization region R1 and the recessed and raised design unit 8 (the transparentization recessed and raised design unit 8A) are associated with each other. Further, in the modification example illustrated in Fig.
  • the outlines of the transparentization regions R1 are positioned outside of the outlines of the recessed and raised design units 8 (the transparentization recessed and raised design units 8A) in such a manner that the transparentization regions R1 cover the recessed and raised design units 8 (the transparentization recessed and raised design units 8A), but the outlines of the transparentization regions R1 may be positioned inside of the outlines of the recessed and raised design units 8 (the transparentization recessed and raised design unit 8A).
