Description

Packaging and tobacco products

[0001] The present disclosure relates to packaging and tobacco products.

[0002] Conventionally, tobacco products have been packaged in hard packages, soft packages, etc. To prevent deterioration of quality, these packages have been wrapped in biaxially oriented polypropylene (OP) film.

[0003] It has also been proposed to use an outer wrapper comprising a first polymer layer and a second polymer layer, which may be heat-sealable layers, and a cellulosic layer for packaging aerosol-generating articles (see, for example, Patent Document 1).

[0004] International Publication No. 2023 / 006928

[0005] The present disclosure aims to improve sustainable packaging that can preserve the quality of the contents and eliminates the need for a plastic outer film.

[0006] A package according to the present disclosure includes a barrier paper for packaging a content containing a tobacco article, the barrier paper being a heat-sealable paper material having barrier properties, the barrier paper being provided with a tear tape that guides a user in a direction to tear the barrier paper when opening the barrier paper, and the barrier paper includes an adhesive region that is heat-sealed to adhere to the content, on the side of the barrier paper defined by the tear tape opposite the region that is removed when opening.

[0007] A package according to another aspect of the present disclosure includes a barrier paper for packaging a container containing a tobacco article, the barrier paper being a heat-sealable paper material having barrier properties, and including a base layer on at least a portion of the front side of the barrier paper that improves the opacity of the barrier paper, and a print layer on the base layer that provides a predetermined design.

[0008] This allows for the quality of the contents to be maintained and allows for improved sustainable packaging by eliminating the need for plastic outer wrapping films.

[0010] Hereinafter, an embodiment of a package according to the present disclosure will be described with reference to the drawings.

[0011] <Embodiment> Fig. 1 is a perspective view showing an example of a tobacco product 1 in which a tobacco article is packaged. Fig. 2 is an exploded perspective view showing an example of the tobacco product 1. The tobacco product 1 includes a contained item 2, for example a tobacco article, an inner wrapper 3 that packages the contained item 2, a wrapper (wrapper paper) 4 that wraps the outside of the inner wrapper 3, a seal paper 5, and a barrier paper 6. The inner wrapper 3, the wrapper 4, and the seal paper 5 form a contained item 11 that packages the contained item 2. The structure and material of the contained item 11 can be similar to those of existing soft packages. The barrier paper 6 is an outer wrapper material that packages the contained item 11. The barrier paper 6 is a paper material in which a barrier coating layer with barrier properties is formed on at least one surface of a base material that mainly contains cellulose. The barrier properties include at least one of water vapor barrier properties. The tobacco product 1 according to this embodiment has a rectangular parallelepiped shape. The barrier paper 6 is folded into a rectangular parallelepiped shape to package the contents 11, forming a front surface 61, a back surface 62, a left side surface 63, a right side surface 64, a top surface 65, and a bottom surface 66. The barrier paper 6 may also have a tear tape 67 to guide the direction in which the barrier paper 6 is to be torn when opening the tobacco product 1. The tear tape 67 may be made of film or paper. A tear tab 671 is provided at one end of the tear tape 67 located on the right side surface 64. The tear tab 671 is a tab that serves as a starting point for the opening operation. A predetermined design 68 may also be printed on at least a portion of the barrier paper 6.

[0012] In this embodiment, for convenience, the directions of up, down, front, back, left, and right are defined as shown by arrows in Figures 1 and 2. That is, the surface of the contained item 11 that the user opens is referred to as the top surface (upward), and of the two larger surfaces, the one with the main design, for example, is referred to as the front surface (frontward). In Figure 1, the front surface 61, right side surface 64, and top surface 65 of the barrier paper 6 are visible. In addition, a tear tape 67 is provided around the side edges of the barrier paper 6 (i.e., the right side surface 64, front surface 61, left side surface 63, and back surface 62) near the top surface 65. When opening, the user tears the barrier paper 6 along the tear tape 67 and removes the portion above the tear tape 67. Furthermore, the user tears the top surface of the package 4 to create an opening.

[0013] The contained object 2 contained in the package 12 including the content 11 and the barrier paper 6 is not particularly limited, and may be a tobacco article such as cigarettes (filter cigarettes, cut-off cigarettes (no filter)), cigars, cigarillos, snus, snuff, chewing tobacco, electronic cigarettes, etc. The contained object 2 shown in Figure 2 is, for example, a plurality of cigarettes.

[0014] The inner wrapping material 3 is made of, for example, paper, and may be aluminum-laminated paper. The inner wrapping material 3 houses the contents 2 in what is known as caramel wrapping (laminated wrapping). The wrapper 4 is made of, for example, paper. The wrapper 4 houses the contents 2 wrapped in the inner wrapping material 3 in caramel wrapping with an open top. The sealing paper 5 is made of a specified paper material, and is adhered to the upper front, top, and upper back of the contents 11. It is noted that the contents 11 does not have to have at least one of the wrapper 4 and the sealing paper 5.

[0015] (Barrier Paper) The barrier paper 6 is a paper material in which a barrier coating layer is formed on at least one side of a base paper. In this embodiment, the barrier coating layer is formed on the entire back surface of the barrier paper 6. The barrier coating layer is formed from a coating material containing a specific polymer, such as an olefin-based, acrylic-based, silicone-based, or fluorine-based resin, and has specific barrier properties. Note that the taste of tobacco articles may change depending on the amount of water vapor in the article. To avoid this, the water vapor permeability of the barrier paper 6 is set to 20 g / m ２ ・day or less, and 9 g / m ２ It is more preferable that the density is 7 g / m or less. ２ It is more preferable that the coating amount of the coating material is 8 gsm (g / m ２ ) or more. The coating weight of the coating material is, for example, 11 gsm or less. The barrier coat layer may have heat sealability, which allows it to be welded by heating.

[0016] The water vapor permeability is a value measured at a portion of the substrate where the coating material is applied, in accordance with JIS Z0208 "Test method for moisture permeability of moisture-proof packaging materials (cup method)."

[0017] It is preferable that the substrate on which the barrier coat layer is formed has high smoothness. By improving the smoothness, a uniform barrier coat layer can be formed, and the amount of coating material required to obtain the desired barrier properties can be reduced. In order to fill the substrate and improve the smoothness, a clay coat layer or an anchor varnish layer may be formed between the substrate and the barrier coat layer. The clay coat layer can be formed, for example, by applying a coating liquid in which clay and a water-dispersible polymer are dispersed in a medium to the substrate and drying it. The anchor varnish layer can be formed by applying a general anchor varnish.

[0018] A design 68 of the package 12 may be printed on at least a portion of the surface of the barrier paper 6. The design 68 may include health warnings. Furthermore, a heat seal layer formed by applying a heat seal agent may be formed on at least a portion of the surface of the barrier paper 6. The heat seal agent may be, for example, polypropylene, polyethylene, polyurethane, polyolefin, rosin ester, resin hot melt adhesive, polyamide, polyester, or the like. The heat seal agent can improve the adhesiveness of the barrier paper 6. Each layer, including the barrier coat layer, may be formed on the substrate using an existing coater machine, or may be formed on the substrate by a printing method such as gravure printing, offset printing, or flexographic printing.

[0019] FIG. 3 shows an example of a blank B6 before it is folded into a rectangular parallelepiped shape. The direction in which the region of the blank B6 that will form the top surface 65 after folding is located is referred to as "upper," "lower," "lower," "left," and "right," for convenience. The surface that will become the outside of the package is referred to as the front of the blank, and the surface that will become the inside of the package is referred to as the back of the blank. The blank B6 in FIG. 3 represents the surface of the barrier paper 6 punched out for one package. For example, the above-described layers are formed in predetermined regions in advance, and the blank B6 is punched out from a roll of base paper. The base paper is aligned and cut based on register marks (eye marks) so that printing, heat sealing agent, and the like are positioned in the desired positions on the blank B6 for one package. That is, register marks, which are predetermined shapes, are attached to the base paper.

[0020] The blank B6 is rectangular in its punched state (in other words, in its unfolded state before folding). The dashed-dotted line in Figure 3 indicates the fold line along which the contents 11 are folded to form a mountain fold when packaging the contents 11. The hatched areas in Figure 3 may be coated with varnish to protect the printing on the barrier paper 6. Note that a predetermined printing may be applied between the varnish and the base material. The white areas in Figure 3 (non-hatched areas) may have a heat-seal layer formed thereon. The heat-seal layer is preferably formed in the area where the front and back of the barrier paper 6 are overlapped during caramel packaging (in other words, the area not exposed on the outer surface of the tobacco product 1), but may also be formed in an area exposed on the outer surface of the tobacco product 1. The two-dot-dash line in the blank B6 indicates the position where a tear tape 67 is affixed to the back surface of the barrier paper, for example.

[0021] The blank B6 includes a front region 610 that forms the front surface when packaged, a back region 620 that forms the back surface 62, a left side region 630 that forms the left side, right side regions 641 and 642 that form the right side, top regions 651 to 659 that form the top surface 65, and bottom regions 661 to 669 that form the bottom surface. As shown in FIG. 3 , the right side region 642, the back region 620, the left side region 630, the front region 610, and the right side region 641 are connected in this order from left to right. The top regions 657 and 653 are trapezoidal regions connected above the front region 610 and the back region 620, respectively. The top regions 651, 655, and 659 are rectangular regions connected above the right side region 642, the left side region 630, and the right side region 641, respectively. Furthermore, triangularly folded top surface regions 652, 654, 656, and 658 are connected between top surface regions 651, 653, 655, 657, and 659, respectively. Similarly, bottom surface regions 667 and 663 are trapezoidal regions connected downward to front surface region 610 and back surface region 620, respectively. Bottom surface regions 661, 665, and 669 are rectangular regions connected downward to right surface region 642, left surface region 630, and right surface region 641, respectively. Furthermore, triangularly folded bottom surface regions 662, 664, 666, and 668 are connected between bottom surface regions 661, 663, 665, 667, and 669, respectively.

[0022] (Packaging) Figure 4 is a diagram illustrating the folding of the bottom of the barrier paper 6. (A) shown in the upper part of Figure 4 shows the state in which the barrier paper 6 has been used to wrap the front, left and right sides, and back of the contents 11, and then the bottom areas 661, 665, and 669 of the barrier paper 6 have been folded in. At this time, the bottom areas 662 and 664 are folded over the bottom area 663, and the bottom areas 666 and 668 are folded over the bottom area 667, and for example, the barrier material coated on the back of the barrier paper 6 in each of the folded areas is bonded together by heat sealing.

[0023] The second row of Figure 4 (B) shows the state in which the bottom area 667 of the barrier paper 6 is further folded in. The bottom area 666 shown in Figure 4 (A) overlaps with a part of the bottom area 665, and the bottom area 668 overlaps with a part of the bottom area 669, with the heat sealing agents provided on the respective surfaces being bonded together.

[0024] The third row of Figure 4 (C) shows the state in which the bottom region 663 of the barrier paper 6 is further folded in. The bottom region 664 shown in Figure 4 (B) overlaps parts of the bottom regions 665 and 667, and the bottom region 662 overlaps parts of the bottom regions 661, 667, and 669. The vertical length (front-to-back direction in Figure 4) of the trapezoidal bottom regions 663 and 667 is greater than half the length of the short side of the bottom of the package, and the bottom regions 663 and 667 overlap near the center of the bottom. The heat-sealing agents applied to the surfaces of the folded bottom regions are then bonded together or the heat-sealing agent and the barrier material are bonded together by heat sealing.

[0025] In this way, the barrier paper 6 can seal the contents 11. The barrier paper 6 can be heat-sealed using a packaging machine for conventional packaging with outer film. That is, the adhesive portion of the barrier paper 6 is the same as that of conventional outer film, and the tobacco product 1 can be manufactured without significant modifications to conventional cigarette manufacturing machines. Heat sealing may be performed using a coating material for forming the barrier coat layer described above, or by providing an additional heat-sealing layer. The heat-sealing layer can improve the adhesiveness of the barrier paper 6. The thinner the substrate of the barrier paper 6, the better its thermal conductivity, shortening the time required for heat sealing by the manufacturing machine. However, if the substrate is too thin, it may be difficult to handle with existing packaging machines. The basis weight of the substrate is preferably 25 gsm or more and 60 gsm or less.

[0026] (Printing Base) If the base material has the above-mentioned basis weight, the design applied to the contained item 11 can also be seen through the barrier paper 6. For example, management information such as the manufacturing date may be written on the contained item 11 so that it can be seen through the barrier paper 6. However, even if the barrier paper 6 is translucent, the visibility and readability of the design applied to the contained item 11 will be reduced because it is covered by the barrier paper 6. Therefore, as described above, a predetermined design may be applied to the surface of the barrier paper 6. When printing on the surface of the barrier paper 6, a base layer may be further formed to improve the opacity (concealment) of the barrier paper 6.

[0027] Figure 5 is a schematic cross-sectional view of the barrier paper 6. The front side of the barrier paper 6 is located outside the tobacco product 1, and the back side is in contact with the contents 11. The barrier paper 6 is partially folded over at the right side 64, top surface 65, and bottom surface 66 shown in Figures 1 and 2. The barrier paper 6 includes a substrate 600, a barrier coat layer 601, heat-seal layers 602 and 603, a printing layer 681, a base layer 682, and a protective layer 683. The heat-seal layer 602, the printing layer 681, the base layer 682, and the protective layer 683 may be formed on only part of the barrier paper 6, rather than over the entire surface.

[0028] The substrate 600 is a cellulose layer primarily containing cellulose. A design 68 is applied to the front side of the substrate 600. The design 68 includes a printing layer 681 on which characters, figures, etc. are printed using an existing pigment-containing ink, a base layer 682 formed under the printing layer 681 like an anchor coating, and a protective layer 683 formed on the printing layer 681. The base layer 682 may be a colored ink, such as white, or a predetermined opacifying agent. The opacifying agent suppresses transparency and improves concealment. By providing the base layer 682, the visibility and readability of the printing layer 681 can be improved even if a design is applied to the surface of the contained item 11. The protective layer 683 is formed of a varnish, such as an existing overprint (OP) varnish or a UV-curable varnish. The protective layer 683 protects the printing layer 681 and prevents color fading. A barrier coat layer 601 with barrier properties is formed on the back side of the substrate 600.

[0029] (Heat Sealing) As shown in FIG. 5 , a heat seal layer 602 may be formed at a predetermined position on the outside of the protective layer 683. Alternatively, the design 68 may not be formed in the area where the heat seal layer 602 is to be formed, and the heat seal layer 602 may be formed on the substrate 600. As described above, the heat seal layer 602 has heat sealing properties that allow it to be welded by heating. Providing the heat seal layer 602 improves the adhesiveness of the folded portion of the barrier paper 6. As shown in FIGS. 3 and 4 , the heat seal layer may not be provided on the outer surface after caramel packaging. However, if the heat seal layer is not provided in at least the area of ​​the outer surface after caramel packaging that faces the heater of the packaging machine (i.e., the area that will be bonded by heat sealing), accumulation of heat sealing agent on the heater of the packaging machine can be prevented. If the barrier coat layer 601 has heat sealing properties, the barrier coat layer 601 can be bonded to the design 68 or the substrate 600 by heat sealing without providing the heat seal layer 602.

[0030] A heat seal layer 603 may be formed at a predetermined position inside the barrier coat layer 601. The heat seal layer 603 is provided on at least a portion of the bottom side of the tear tape 67 (i.e., the side opposite the area of ​​the barrier paper 6 that is removed upon opening) in FIGS. 1 and 2 . The heat seal layer 603 bonds the barrier paper 6 to the contents 11, preventing the barrier paper 6 from falling off. By providing the heat seal layer 603 on, for example, the right side surface 64 or the bottom surface 66, the product can be manufactured without modifying an existing packaging machine that heat seals caramel packaging. Meanwhile, by providing the heat seal layer 603 on areas where the barrier paper 6 does not overlap, such as the front surface 61, back surface 62, or left surface 63, adhesion to the heat seal layer 603 can be facilitated.

[0031] Alternatively, the heat seal layer 603 may be provided along the tear tape 67, near the bottom side of the tear tape 67. Figure 6 is a diagram illustrating an adhesive region 69 where the heat seal layer 603 is provided along the tear tape 67. The adhesive region 69, for example, includes at least the hatched area between the dashed lines in Figure 6. In the example of Figure 6, the adhesive region 69 is provided under the tear tape 67 along the side periphery of the barrier paper 6 (i.e., the right side 64, front 61, left side 63, and back 62). When the paper substrate 600 is torn using the tear tape 67, there is a risk of the tearing occurring in an unintended direction depending on the direction of the paper fibers. By bonding the barrier paper 6 and the contents 11 together along the tear tape 67 near the bottom side of the tear tape 67 using the heat seal layer 603, the tear direction of the barrier paper 6 can be guided when the tobacco product 1 is opened. In other words, tearing away from the adhesive portion of the tear tape 67 and toward the bottom side of the barrier paper 6 can be prevented. By providing an adhesive region 69 around the entire side periphery, the tearing direction can be reliably guided, and the barrier paper 6 and the contents 11 can be reliably adhered together even after opening, preventing the barrier paper 6 from falling off.

[0032] The adhesive region 69 does not have to be bonded along the entire periphery of the barrier paper 6. For example, the adhesive region 69 may be provided at least on the surface (right side surface 64) where the tear tab 671 is located. Specifically, an area 691 near the tear tab 671 may be bonded. The area 691 is a predetermined range of the right side surface 64 that faces the tearing direction from the tear tab 671 and is located near the bottom side of the tear tape 67. By guiding the tearing direction near the starting point of the opening operation, the overall direction of the operation can be appropriately controlled. Furthermore, the right side surface 64 where the tear tab 671 is provided is located in a position that can be bonded using existing manufacturing machines that perform heat sealing, so there is no need to significantly modify the manufacturing machine. Furthermore, during manufacturing, bonding the barrier paper 6 and forming the adhesive region 69 can be performed in a single heat treatment, which is efficient. The adhesive region 69 may be further provided on at least a portion of the front surface 61, the left side surface 63, and the back surface 62, or may be provided intermittently in a dashed line pattern on at least a portion of the front surface 61, the left side surface 63, and the back surface 62.

[0033] The heat seal layer 603 may be provided on the barrier paper 6 side and heat sealed, or on the envelope 4 side and heat sealed. Instead of or in addition to heat sealing, the barrier paper 6 may be half-cut or other weakened line to guide the tearing direction. The weakened line can be formed by half-cutting the substrate 600 or the like so as not to cut the barrier coat layer 601, thereby ensuring the water vapor barrier properties of the barrier paper 6. Alternatively, the tear tape 67 may be omitted and the package may be opened using a zipper whose boundary is defined by two weakened lines.

[0034] <Effects> Furthermore, by airtightly packaging the contents 11 using the barrier paper 6, it is possible to prevent volatile components contained in the contents 2 from leaking out of the package. This eliminates the need for packaging with, for example, a plastic outer film. While typical cigarette packaging relies on the barrier properties of the outer film to prevent quality deterioration, this embodiment makes it possible to achieve a sustainable packaging form that omits the outer film.

[0035] <Modifications> Unless otherwise specified, the dimensions, materials, shapes, relative positions, etc. of the components described in the embodiments are not intended to limit the technical scope of the present disclosure. Furthermore, the configurations shown in the embodiments can be combined or modified in various ways without departing from the spirit of the present disclosure.

[0036] The contents 11 may be a so-called hard package instead of a soft package.

[0037] In the embodiment, the area where the front and back surfaces of the barrier paper 6 are overlapped and bonded by heat sealing may be so-called palm-to-toe bonding. That is, the back surfaces of the barrier paper 6 may be overlapped, and the barrier coat layer 601 or heat seal layer 603 formed on each back surface may be bonded by heat sealing.

[0038] The protective layer 683 shown in FIG. 5 may have heat-sealing properties that allow it to be welded by heating. In other words, the protective layer 683 may be formed from a heat-sealing agent. In this case, the heat-sealing agent is preferably a polymer that has the properties of a varnish, which is relatively transparent and can protect the print, and has heat-sealing properties. In this case, the heat-sealing agent is applied to the front side of the printed layer 681 and between the barrier papers 6 (the front side) that are overlapped when packaging the caramel candy. The protective layer 683 formed from the heat-sealing agent can also protect the printed layer 681. Furthermore, there is no need to provide an additional heat-sealing layer 602 on the protective layer 683, which reduces the number of manufacturing steps.

[0039] 5 may be an adhesive layer that bonds the barrier paper 6 to the contents 11 using an adhesive other than heat sealing, such as glue, adhesive tape, or cold sealing agent. Even when an adhesive other than heat sealing is used, by forming an adhesive area along and near the tear tape 67, it is possible to guide the direction in which the tear tape 67 tears the barrier paper 6.

[0040] The above-mentioned control information may be written on an area where the barrier paper 6 is not overlapped, such as the front, back, or left side. Conventionally, control information has generally been written on the bottom of the contained item 11, but in the tobacco product 1 of this embodiment, visibility is reduced in the area where the barrier paper 6 is overlapped. Therefore, when control information such as the manufacturing date is written on the contained item 11 and can be seen through the barrier paper 6, it is preferable to write it on an area where the barrier paper 6 is not overlapped.

[0041] The opacifying agent is not particularly limited, and known opacifying agents can be suitably used, including white pigments such as titanium dioxide, zinc sulfide, zinc oxide, barium sulfate, calcium carbonate, talc, or mica, and black pigments such as carbon black or composite oxide pigments. Such opacifying agents can be applied in a molten state and then cured; by applying a solution in which the opacifying agent is dissolved or dispersed in a solvent and then removing the solvent to cure; by printing using various printing means such as flexographic printing; or by forming an extruded resin into a film. The solvent is not particularly limited as long as it can dissolve or disperse the opacifying agent.

[0042] The above-mentioned opacifying agents may be used alone or in any combination of two or more types. The base layer 682 may be composed of multiple layers, for example, a layer containing a black pigment on the inside of the package and a layer containing a white pigment on the outside of the package. In this way, the opacifying properties of the barrier paper 6 can be further improved and the barrier paper 6 can be made light-blocking, compared to when only a layer containing a white pigment is used as the opacifying layer.

[0043] The volume average particle diameter of the opacifying agent used in the material of the concealing layer is not particularly limited, but is usually 0.01 μm or more, preferably 0.1 μm or more, and more preferably 0.5 μm or more, and is usually 50 μm or less, preferably 10 μm or less, and more preferably 2 μm or less. The volume average particle diameter of the opacifying agent used in the material of the concealing layer can be obtained by measuring the raw material opacifying agent by a known method.

[0044] The resin used in the masking agent is not particularly limited, and known resins can be suitably used. For example, natural resins such as rosin-based resins, and synthetic resins such as acrylic-based resins can be used.

[0045] The ink material used for the concealing layer is not particularly limited as long as it can dissolve or disperse the above-mentioned concealing agent. In addition to the above-mentioned concealing agent, examples of the ink material include, but are not limited to, a solvent, a dispersant, a viscosity modifier, and an antifoaming agent.

[0046] The thickness of the coating of the opacifying agent is not particularly limited, but is usually 0.1 gsm or more, preferably 1 gsm or more, and more preferably 2 gsm or more, and is usually 15 gsm or less, preferably 10 gsm or less, and more preferably 5 gsm or less. When the base layer 682 is composed of multiple opacifying agent layers, the above thickness may be treated as the overall thickness or may be treated as the thickness of each layer.
