Description

  The present invention relates to tissue paper products, and more particularly to scented tissue paper products that emit a scent.

  A bundle of tissue paper is stored in a storage box, and the tissue paper is sequentially put into a set (one set) from an outlet provided on the upper surface of the storage box (also referred to as a carton box or carton). Tissue paper products that are pulled out and used are well known. The take-out method is a pop-up type in which when one piece is taken out, a part of the next piece is continuously drawn out from the take-out port.

  Among the tissue paper products, there is a product that emits a scent. This scented tissue paper product should be moderately scented continuously rather than the one that has a strong scent temporarily. With scented tissue paper products, it is stable until the user uses up the tissue paper. Therefore, it is required to have a proper scent continuously.

  Conventional scented tissue paper products are products in which fragrance is applied to the tissue paper itself, or the fragrance encapsulated in microcapsules is carried on the portion where tissue paper and storage box slide when tissue paper is removed, and microcapsules are removed at the time of removal. There is a product that breaks down and causes the fragrance inside to adhere to tissue paper and volatilize around.

  However, the product with fragrance added to the former tissue paper itself will have fragrance attached to the entire manufacturing equipment when manufacturing tissue paper, so a dedicated line for manufacturing scented tissue paper is required, and the manufacturing cost is low. There was a problem of being expensive. Moreover, when the fragrance | flavor was directly provided to the tissue paper itself, when smelling a nose with tissue paper, there existed a problem that a fragrance was felt too strongly. On the other hand, if perfume is given to the tissue paper itself, the perfume will be volatilized in the storage box, and the perfume will diffuse through the carton base paper and spread outside, especially when the storage period is long, etc. There was a case where the fragrance was not felt.

  On the other hand, the product with the latter microcapsules slidable does not change so much until the tissue paper and storage box slide from the start of use to the end of use. However, it was difficult to develop a stable scent strength continuously. In addition, many perfumes were given to tissue paper at the beginning of use, and there was a problem that if the nose was bitten with tissue paper, the scent was felt too strongly. Further, there is a problem that a complicated manufacturing process for encapsulating the fragrance in the microcapsule is required and the yield when the fragrance is encapsulated in the microcapsule is low and the cost is high.

  Thus, the conventional scented tissue paper product has problems such as complicated production and high production cost, too strong scent at the beginning of use, insufficient scent expression after storage to some extent, I was not fully satisfied with the continuous and stable scent.

  Therefore, the main problem of the present invention is that it is easy to manufacture, low in manufacturing cost, has a sufficient scent even when the storage period is long, and has a scent that allows a moderate scent to be emitted stably from the start of use. To provide tissue paper products.

The present invention that has solved the above problems is as follows.
[Invention of Claim 1]
A sheet material provided with a slit on the inner surface of the upper surface of the paper box in which an annular opening perforation line for forming an outlet is formed on the upper surface is within a range in which the slit is surrounded by the perforation perforation line. A tissue paper product having a storage box affixed to be positioned and a tissue paper bundle in which tissue paper stored in the storage box is folded and laminated,
The sheet material is integrated such that the inner resin film layer and the outer resin film layer are inseparable by an adhesive layer or an adhesive layer interposed therebetween, and a fragrance is added to the adhesive layer or the adhesive layer. contained, said outer resin film layer is the permeability of the gas than the inner resin film layer is rather high, the perfume is released to the outside through the outer plastic film layer and the inner resin film layer is accommodated Facing the tissue paper bundle stored in the box, the outer resin film layer facing the inner surface of the storage box, affixed to the storage box,
By cutting off the area surrounded by the perforation line for cleavage, the sheet material is exposed with the surface of the outer resin film layer facing outward,
A scented tissue paper product.

[Invention of Claim 2]
The tissue paper product with a fragrance according to claim 1, wherein a gas barrier layer is provided at least in a portion facing the sheet material of the paper box.

[Invention of Claim 3]
The inner resin film layer is any one of a polyethylene terephthalate film and a polyvinylidene chloride film, and the outer resin film layer is any one of a polyethylene film, a polystyrene film, a polypropylene film, and a polycarbonate film, and the pressure-sensitive adhesive layer. Or the tissue paper product with a fragrance of Claim 1 or 2 whose adhesive layer is any one of the layer of a natural rubber adhesive, a natural rubber latex adhesive, an acrylic adhesive, and a hot-melt adhesive .

[Invention of Claim 4 ]
The thickness of the inner resin film layer is 5 to 30 [mu] m, 10 to 100 [mu] m thickness of the outer resin film layer, any one of claims 1 to 3 the thickness of the pressure-sensitive adhesive layer or an adhesive layer is 5~80μm Tissue paper products with fragrance as described in 1.

[Function and effect]
In the present invention, the sheet material is formed by integrating the inner resin film layer and the outer resin film layer with an adhesive layer or an adhesive layer containing a fragrance, and the outer resin film layer is the inner resin film. The gas permeability was higher than that of the layer.

  Therefore, in the sheet | seat material which concerns on this invention, when the fragrance | flavor contained in an adhesive or an adhesive volatilizes, it diffuses outside through an outer side resin-made film layer rather than an inner side resin-made film layer.

  In the present invention, such a sheet material is formed such that the inner resin film faces the tissue paper bundle, and the outer resin film is formed on the inner surface of the storage box, in particular, where the annular perforation line for forming the outlet is formed. Attached to the paper box with the facing relationship. Therefore, particularly in the unused state where the perforation line for cleavage is not cleaved, the fragrance is slightly diffused through the slit of the sheet material to the tissue paper bundle in the storage box, An excessively strong fragrance is not imparted to the tissue paper constituting the tissue paper bundle, and the fragrance of the tissue paper is not too strong at the beginning of use.

Further, in the tissue paper product with fragrance according to the present invention, the perforation line for cleavage is cleaved to form the outlet, and when the tissue paper is taken out from the slit, a part of the next tissue paper is exposed to the outside from the slit Thus, the tissue paper is supported by the slit. In the tissue paper product with scent according to the present invention, the fragrance is volatilized and applied from the exposed outer resin film surface located in the periphery to a part of the tissue paper exposed to the outside from the slit at this time. The Further, in the sheet material according to the present invention, the slit-section, by slightly contacting with the pressure-sensitive adhesive layer or an adhesive layer on tissue paper to be drawn through a slit to expose the pressure-sensitive adhesive layer or an adhesive layer, when the An aroma can be imparted to tissue paper. Thus, in the tissue paper with a fragrance of this invention, since a fragrance | flavor is provided to tissue paper in the space of the open | released storage box outer surface side, it becomes a tissue paper of the moderate fragrance which a fragrance is not too strong. On the other hand, even after opening, the tissue paper bundle of the storage box is slightly fragrant through the slit or from the slit cross section, so that it does not become tissue paper with no scent at all.

  Further, in the present invention, since the fragrance is contained in the pressure-sensitive adhesive layer or the adhesive layer that adheres both film layers and diffused through the resin film layer, the fragrance diffuses from the exposed fragrance layer or the like. Since a small amount of fragrance gradually diffuses from the outer resin film surface of the sheet material as compared to the case, the fragrance will diffuse around the outer side of the storage box, particularly on the outer side of the storage box, over a long period of time. Therefore, even if the storage period is long, the scent is sufficiently felt. Of course, even after the start of use, a moderate subtle fragrance is continuously and stably emitted.

  Furthermore, in the tissue paper with fragrance of the present invention, when the outlet is formed, the fragrance is volatilized outward from the exposed outer resin film surface, so that the fragrance can be felt like a stationary fragrance. There is also.

  Moreover, the tissue paper product of the present invention can adjust the gas permeability by selecting the film type of the inner resin film and the outer resin film, and can easily adjust the release property.

  On the other hand, since the trace amount of fragrance | flavor is diffused gradually as above-mentioned in this invention, the usage-amount of fragrance | flavor itself can be decreased.

  Further, in the present invention, a fragrance is contained in the pressure-sensitive adhesive or adhesive for bonding the inner resin film layer and the outer resin film layer. However, the pressure-sensitive adhesive or adhesive is easily thinned by coating and coating, etc. Can be formed. Therefore, in this invention, a fragrance | flavor can be fixed reliably over the wide range of a sheet | seat material, and the usage-amount can be reduced.

  Furthermore, since the tissue paper product of the present invention has a fragrance carried on the sheet material, not the tissue paper itself, it is not necessary to impart the fragrance to the tissue paper itself. Therefore, the problem at the time of giving a fragrance | flavor to tissue paper itself is solved. In addition, the equipment for applying the fragrance to the sheet material is small compared with the tissue paper production equipment, and the production cost is significantly reduced.

  Here, in the tissue paper with a fragrance according to the present invention, the fragrance is volatilized from the outer resin film layer to the outside in small amounts, so the fragrance persists as it is, but in particular, at least the part of the paper box that faces the sheet material, in other words, If a gas barrier layer is provided on the part facing the outer resin film layer, the risk of perfume permeating through the paper box and evaporating out of the storage box during storage is greatly reduced, and it can be stored for a longer period of time. .

On the other hand, in the sheet material of the present invention, the outer resin film has an oxygen permeability of 700 cc / m ² · 24 h · atm or more and a carbon dioxide gas permeability of 4000 cc / m ² · 24 h · atm or more, The inner resin film preferably has an oxygen permeability of less than 200 cc / m ² · 24 hatm and a carbon dioxide gas permeability of less than 900 cc / m ² · 24 h · atm . If it does in this way, while an inner side resin film layer will exhibit gas barrier property, an outer side resin film layer will have moderate gas permeability, and the effect of this invention will be ensured. In addition, the permeability | transmittance of oxygen and a carbon dioxide gas (carbon dioxide gas) concerning this invention is the value measured according to JISK7126 at the temperature of 25 degreeC.

  The inner resin film layer is preferably a polyethylene terephthalate film or a polyvinylidene chloride film because of its excellent gas barrier properties and low cost.

  On the other hand, the outer resin film layer is preferably a polyethylene film, a polystyrene film, a polypropylene film, or a polycarbonate film because of excellent perfume permeability and low cost.

  Further, when the inner resin film layer has a thickness of 5 to 30 μm, the outer resin film layer has a thickness of 10 to 100 μm, and the adhesive layer or the adhesive layer has a thickness of 5 to 80 μm, the rigidity of the sheet material is excessive. Without being raised, it becomes easy to ensure the pullability of the tissue paper and the supportability of the tissue paper by the slit edge.

  As described above, according to the present invention, the scent is easy to manufacture, the manufacturing cost is low, the scent is sufficiently felt even when the storage period is long, and the scent can be emitted stably and stably from the start of use. Tissue paper products are provided.

It is a perspective view of the sanitary thin paper storage box which concerns on this invention. It is an example of the expanded view of the sanitary thin paper storage box which concerns on this invention. It is a perspective view for demonstrating especially the structure of a side short surface of the sanitary thin paper storage box which concerns on this invention, and an outlet. It is a perspective view at the time of use of the sanitary thin paper storage box which concerns on this invention. It is AA sectional drawing of FIG. It is the figure which looked at the upper surface from the box inner side for demonstrating the sheet | seat material which concerns on this invention.

Next, embodiments of the present invention will be described in detail below with reference to the drawings. 1 to 6 show a tissue paper product 100 according to the present invention.
The tissue paper product 100 according to the present invention has a tissue paper bundle 2 in which a plurality of tissue papers 2t, 2t... Are folded and folded, and an upper surface 11 has an annular tearing perforation line 20 for forming an outlet. When the tissue paper 2t is stored in the formed storage box 1 and the tissue paper 2t is taken out from the take-out port 20X at the time of use, a part of the lower stacked tissue paper is exposed from the take-out port 20X. Is.

  The storage box 1 according to the present invention is a rectangular parallelepiped box called a carton box, and has a product appearance. The storage box 1 includes a paper box 10 having an annular tearing perforation line 20 for forming an outlet 20X on the upper surface 11, and a sheet material 30 covering a range 20a surrounded by the perforation line 20 from the inside of the paper box. Have.

  The paper box 10 is a box body that uses paper or a paper processing material that forms the outline of the storage box 1 as a base material, and the structure of the paper box of a known storage box is adopted for the size, shape, developed shape, and the like. The paper box may be appropriately printed on the inner or outer surface. The size of a general storage box is approximately 110 to 320 mm for the long edge L1, 70 to 200 mm for the short edge L2, and about 40 to 150 mm for the height L3. The storage box 1 according to the present invention also has this size. can do.

Moreover, as long as the base material of the paper box 10 has the subject of this invention, the well-known paper raw material which uses various pulps, such as virgin pulp and a waste paper pulp, as a main raw material can be employ | adopted, The material of the suitable paper box 10 is Coated cardboard having a basis weight of 250 to 500 g / m ² .

  As shown in FIGS. 2 and 3, the structure of the paper box 10 of the present embodiment is such that the bottom surface 12 and one long side surface 13 are glued with a glue margin 12A to form a cylinder, and then the top surface 11, the bottom surface 12 and these Flaps F, F... Extending from the long side surface 13 connecting the two are folded back to the inner surface of the box, and the contact portions of the flaps F, F. It has become. The paper box 10 of the present invention is not limited to this structure.

  On the other hand, the tearing perforation line 20 formed on the upper surface of the paper box 10 has an annular shape and is configured with an appropriate cut tie ratio. The perforation line 20 for cleaving can be constituted by a double perforation line, a zipper perforation line, or the like in addition to a normal perforation line. Only a part may be a double perforation line.

  The perforation line 20 for tearing according to the present embodiment includes long sides 21 and 21 extending in the longitudinal direction of the paper box and short sides 22 and 22 parallel to the short edges connecting the ends of the long sides 21 and 21. The shape of the range 20 a surrounded by the perforation line 20 for tearing is an appropriate shape having a long direction along the longitudinal direction of the storage box 1. In general, a slightly elongated rectangular shape along the longitudinal direction of the storage box 1 or an arch shape in which the central portions of the long sides 21 and 21 of the rectangle are slightly bulged toward the outside of the storage box. It has a close shape. The illustrated form is the latter example.

  On the other hand, the sheet material 30 is larger than the range 21a surrounded by the tearing perforation line 20, and is, for example, a rectangle or an ellipse, and particularly affects the tearing of the tearing perforation line 20 on the inner surface side of the upper surface of the paper box. The adhesive is not applied to the outside of the perforation line 20 for tearing. A slit 31 is formed in the sheet material 30, and the slit 31 is positioned along the longitudinal direction in a range 20 a surrounded by the tearing perforation line 20. Therefore, as shown in FIG. 3 and FIG. 4, by cutting off the range 20a surrounded by the tearing perforation line 20 along the tearing perforation line 20, an outlet 20X is formed on the upper surface 11 of the paper box. The sheet material 30 and the slit 31 formed in the sheet material 30 are exposed through the outlet 20X.

  In addition, the length of the said slit 31 can be made into an appropriate length, and the length considered suitable in relation to the magnitude | size with the known annular perforation line 20 is employable.

  The tissue paper 2t and the like stored as a bundle in the storage box 1 are taken out one by one from the take-out port 20X through the slit 31, as shown in the drawing. And the said slit 31 supports a part of tissue paper 2t exposed from the outlet 20X, and prevents falling into the inside of a storage box.

  The sheet material 30 according to the present invention includes an outer resin film layer 30A, an inner resin film layer 30B, and a pressure-sensitive adhesive layer or adhesive layer 30M containing a fragrance interposed therebetween, and the pressure-sensitive adhesive. The outer resin film layer 30A and the inner resin film layer 30B are bonded and integrated by a layer or an adhesive layer 30M.

  The sheet material 30 has the outer resin film layer 30A facing the inner surface 11i on the upper surface of the storage box, and the inner resin film layer 30B facing the tissue paper bundle 2 stored in the storage box. Thus, it is stuck on the storage box 10.

  In the sheet material 30 according to the present invention, the gas permeability of the outer resin film layer 30A is higher than that of the inner resin film layer 30B, and the fragrance contained in the pressure-sensitive adhesive layer or the adhesive layer 30M is the outer resin. The light is transmitted through the film layer 30A and diffused to the outside.

  The inner resin film layer 30B has a high gas barrier property with respect to the fragrance so as not to dissipate the fragrance to the outside as much as possible. Particularly, the outer resin film layer 30A has a moderate gas permeability for the outer resin film layer 30A. It is good to use what has property, especially a fragrance | flavor weak permeability. The outer resin film layer 30A and the inner resin film layer 30B are not necessarily limited to a single layer structure, and may have a laminated structure.

More specifically, the inner resin film 30B preferably has an oxygen permeability of less than 200 cc / m ² · 24 h · atm and a carbon dioxide gas permeability of less than 900 cc / m ² · 24 h · atm. When the gas permeability is sufficient, sufficient gas barrier properties having a fragrance retention property with respect to most of the fragrances usable in the tissue paper product 100 are exhibited. The outer resin film 30A preferably has an oxygen permeability of 700 cc / m ² · 24 h · atm or more and a carbon dioxide gas permeability of 4000 cc / m ² · 24 h · atm or more. If it has the permeability | transmittance of the said gas, a fragrance | flavor can permeate | transmit a moderately and the effect of this invention can be exhibited reliably.

  In addition, the sheet material 30 according to the present invention adjusts the amount of the fragrance that permeates the inner resin film layer 30B by selecting the film constituting the outer resin film layer 30A, and exhibits appropriate sustained release properties. It can also be done.

  Here, examples of main film materials that can be used for the sheet material 30 of the tissue paper product 100 and the transmittance are shown in Table 1 below.

  As shown in Table 1, as the inner resin film layer 30B of the sheet material 30, a polyethylene terephthalate film and a polyvinylidene chloride film are suitable, and as the outer resin film layer 30A, a polyethylene film, a polystyrene film, and a polypropylene film are used. Polycarbonate films are preferred.

  In particular, the preferred specific film type combination of the outer resin film layer 30A and the inner resin film layer 30B is a combination of the outer resin film layer 30A being a polypropylene film and the inner resin film layer 30B being a polyethylene terephthalate film. It is. In this combination, polypropylene has moderate gas permeability, polyethylene terephthalate has sufficient gas barrier properties, and there is a large difference in gas permeability between the layers, and the fragrance is volatilized only from the outer resin film layer 30A. Can be made. Further, both the polypropylene film and the polyethylene terephthalate film are inexpensive, and the supportability and pull-out property of the tissue paper 2t required for the sheet material 30 of the tissue paper product 100 can be sufficiently secured.

  On the other hand, the thickness of the sheet material 30 according to the present invention is suitably 20 to 210 μm. If the thickness is less than 20 μm, the strength is insufficient, and the probability of tearing or breaking when the tissue paper 2 t is taken out increases. In addition, it becomes difficult to form a layer structure. If it exceeds 210 μm, there is no problem of strength, but it is hard to pull out the tissue paper 2t. In particular, it becomes difficult to take out the first sheet. Furthermore, the cost is also increased.

  About thickness of each layer 30A, 30M, 30B which comprises sheet material 30, about inner side resin-made film layer 30B, it is desirable that it is 5-30 micrometers. In the sheet material 30 according to the present invention, the fragrance is diffused from the outer resin film layer 30A. However, since this diffusibility can be adjusted by the thickness of the outer resin film layer 30A, the adjustment width of the thickness The inner resin film layer 30B preferably has a small thickness in order to ensure the above-mentioned range. If the thickness is less than 5 μm, the strength tends to be insufficient, and if it exceeds 20 μm, improvement in gas barrier properties cannot be expected, but the possibility that the flexibility of the entire sheet material will be reduced increases.

  On the other hand, the outer resin film layer 30A is preferably 10 to 100 μm, and is preferably 15 to 60 μm in consideration of the general storage period of the tissue paper product 100.

  In particular, when the inner resin film layer 30B and the polyethylene terephthalate film are formed and the thickness is 5 to 30 μm, the outer resin film layer 30A is formed of a polypropylene film and the thickness is 15 to 60 μm, The gas barrier property, the diffusing property, the flexibility of the sheet material, and the pulling-out property of the tissue paper 2t are surely and effectively exerted with good balance.

  On the other hand, the thickness of the pressure-sensitive adhesive layer or the adhesive layer 30M is preferably 5 to 80 μm. If it is less than 5 μm, the outer and inner film layers cannot be securely bonded, and the possibility of partial peeling increases. Also, if it exceeds 80 μm, the flexibility of the sheet material is reduced, and the adhesive, adhesive, and fragrance Cost increases due to increased usage.

  The pressure-sensitive adhesive for forming the pressure-sensitive adhesive layer or the adhesive layer 30M is not particularly limited as long as the films are bonded together so as not to be peeled off. Natural rubber adhesives, natural rubber latex adhesives, acrylic adhesives, hot melt adhesives, and the like. In particular, an acrylic pressure-sensitive adhesive is desirable because it is excellent in the adhesion of a resin film sheet and is excellent in the solubility and dispersibility of the fragrance. As the adhesive, a polyester-based adhesive is desirable because it has excellent affinity with a film and ensures adhesion.

The blending ratio of the fragrance in the pressure-sensitive adhesive layer or the adhesive layer can be determined by the type, volatility, etc. of the fragrance, but from the point of continuously emitting a slight fragrance and not increasing the cost, It may be 0.5 to 15 g / m ² , particularly 3 to 8 g / m ² .

  On the other hand, in the sheet material 30, the pressure-sensitive adhesive layer or the adhesive layer 30M may be present between the outer resin film layer 30A and the inner resin film layer 30B interspersed or with a pattern, preferably In this embodiment, the outer resin film layer 30A and the inner resin film layer 30B are interposed on the entire surface. When the pressure-sensitive adhesive layer or the adhesive layer is interposed on the entire surface, the outer resin film layer 30A and the inner resin film layer 30B are separated from each other at the slit cross section 31C and the edge of the sheet material 30, and the pressure-sensitive adhesive layer Alternatively, there is no possibility that the adhesive layer 30M is exposed and the fragrance is excessively released. Further, the integrity of each layer is increased, and the supportability of the tissue paper 2t at the slit 30 is also ensured.

  In addition, the sheet | seat material 30 which concerns on this invention can be made into the structure where the adhesive layer or adhesive layer 30M is exposed to the cross section 31C of the slit 31. FIG. The fragrance is easily attached to the tissue paper 2t passing through the slit 31, and the fragrance is easily felt during use. In particular, in the case of this structure, it is desirable that the adhesive layer is used because there is no possibility that a sticky adhesive will adhere to the tissue paper drawn out.

  On the other hand, the sheet material 30 of the present embodiment can be formed by a laminating method. For example, on a film sheet for forming one resinous film layer, an adhesive containing a fragrance is applied and applied in advance by a fragrance application means such as a spray coating device, a printing device, or a coating device. Alternatively, after that, a film sheet for forming the other resin film layer is laminated and integrated on the pressure-sensitive adhesive layer forming surface. Thereafter, heat fusion may be performed as necessary. Furthermore, a slit is formed by a cutter, and the sheet material 30 is obtained by appropriately cutting or the like.

  In the tissue paper product 100 according to the present invention, since the fragrance is diffused through the outer resin film layer 30A as described above, the fragrance is not directly taken into a microcapsule, but directly evaporated. It is made to contain in an adhesive layer or an adhesive bond layer in the possible mode.

  Here, although the said fragrance | flavor made to contain in the adhesive layer or adhesive layer 30M is not specifically limited, As a specific example, Ryusen incense, benzoin incense, sea scent incense, ghost cat incense, clove oil, galvanum, jasmine absolute , Natural fragrances such as lavatanam, mate tea, merilot, mimosa, musk tonkin, myrrh, oak moss or moss de chine, milk incense, peony incense, oris, baturi, rosemary oil, sandalwood oil, vetiver oil, violet leaf absolute, higher alcohol, aldehyde , Benzaldehyde, benzoic acid, cinnamic acid, cinnamic aldehyde, cinnamic alcohol, coumarin, ester, indole, ketone, salicylic acid and related compounds, terpenoids, vanillin and other various synthetic fragrances or mixtures of two or more thereof be able to. Commercial products can also be used.

  On the other hand, in the tissue paper product with fragrance according to the present invention, as shown in FIGS. 2, 5, and 6, a gas barrier layer 10 </ b> A is formed in a portion facing the sheet material 30 of the paper box. In the illustrated embodiment, the gas barrier layer 10A is formed in a slightly wider range than the portion facing the sheet material 30. However, the gas barrier layer is not limited to this embodiment, and the gas barrier layer is formed on the entire upper surface inner surface portion of the paper box 10 or the entire inner surface side of the paper box. 10A can be provided. This gas barrier layer 10A reduces the air permeability of the paper box 10 so that the fragrance volatilized from the outer resin film layer 30A permeates the paper layer of the paper box 10 facing and volatilizes out of the storage box 1. It is to prevent. The gas barrier layer 10 </ b> A only needs to reduce at least the air permeability of the paper constituting the paper box 10. It is good also as a layer which has the gas barrier property equivalent to the inner side resin-made film layer 30B or more. Specific examples of the gas barrier layer 10A formed on the inner surface of the paper box include a binder in which one or more of starch, carboxymethyl cellulose, polyvinyl alcohol, and paraffin are mixed; a resin such as vinyl acetate, a vinylidene chloride copolymer resin, and a polyethylene resin. Or a laminate layer obtained by laminating and bonding a resin film such as a polyethylene film or a vinylidene chloride copolymer film. As described above, by providing the gas barrier layer 10A at least in the portion facing the outer resin film layer 30A of the paper box 10, the fragrance evaporated from the outer resin film layer 30A can pass through the paper layer constituting the paper box 10. Therefore, even when stored for a long period of time, it is prevented that the scent is not felt when opened.

  On the other hand, in the tissue paper bundle 2 according to the present invention, the rectangular tissue papers 2t are substantially folded in two, and the edges of the folded pieces are overlapped with each other so that they are positioned on the folded inner surface of the adjacent tissue paper. While being laminated. Here, the term “substantially” means that a slight fold of the edge formed in manufacturing is allowed.

  In the tissue paper bundle 2 having this laminated structure, when one folded piece positioned at the top is pulled upward, the other folded piece adjacent immediately below it is pulled upward by friction and lifted. The tissue paper bundle 2 having such a structure is stored with its uppermost surface facing the upper surface of the storage box 1 having the outlet 20X on the upper surface 11 described above. When the set (one set on the top surface) is pulled out, a part of the other set located immediately below is exposed. Note that the number of tissue papers 2t in the present invention is not limited, but a typical number of sheets of this type of product is 120 to 240 sets.

  The tissue paper bundle 2 can be manufactured by a known interfolder of a multi-stand type or a rotary type.

  On the other hand, the tissue paper 2t constituting the tissue paper bundle 2 has a ply structure in which two to three thin papers are laminated.

  The raw pulp of the thin paper is a mixture of NBKP and LBKP, and may be appropriately combined with waste paper pulp. However, in terms of texture and the like, it is preferably composed only of NBKP and LBKP. In this case, the blending ratio is preferably NBKP: LBKP = 20: 80 to 80:20, and particularly preferably NBKP: LBKP = 30: 70 to 60:40.

The rice tsubo per thin paper constituting each ply of the tissue paper 2t according to the present invention is preferably 9 to 25 g / m ² , more preferably 10 to 15 g / m ² . If the rice tsubo is less than 9 g / m ² , it is preferable from the viewpoint of improving the softness, but it is difficult to ensure adequate strength that can withstand use. On the other hand, when the rice tsubo exceeds 25 g / m ² , the entire paper becomes hard, and a feeling of stickiness is generated, resulting in poor touch. In addition, the US tsubo is based on the JIS P 8124 (1998) US tsubo measurement method.

  On the other hand, the paper thickness of the tissue paper according to the present invention is 100 to 180 μm, more preferably 120 to 140 μm in the state of the product, that is, two sheets of two thin papers and three sheets of three thin papers. Is desirable. If the paper thickness is less than 100 μm, it is preferable from the viewpoint of improving the softness, but it is difficult to ensure adequate strength as tissue paper. On the other hand, if it exceeds 180 μm, the texture of the tissue paper is deteriorated, and a feeling of tingling is generated during use.

  As a method of measuring the thickness of the film used for the paper thickness and the sheet material, the specimen is sufficiently conditioned under the conditions of JIS P 8111 (1998), and then a dial thickness gauge (thickness measuring instrument) “PEACOCK G” is used under the same conditions. Using “type” (manufactured by Ozaki Mfg. Co., Ltd.), the paper thickness is measured in the state of the product, that is, two sheets for two thin papers, three sheets for three thin papers, and the film thickness is measured in a single layer state. The sheet material is measured in the state of the sheet material. Specifically, confirm that there is no dust, dust, etc. between the plunger and the measuring table, lower the plunger on the measuring table, move the memory of the dial thickness gauge to adjust the zero point, and then Raise the plunger, place the sample on the test bench, slowly lower the plunger and read the gauge at that time. At this time, only the plunger is placed. The terminal of the plunger is made of metal and a circular plane having a diameter of 10 mm is perpendicular to the plane of the paper. The load at the time of measuring the thickness is about 70 gf at 120 μm. In addition, let the film thickness used for a paper thickness and a sheet | seat material be an average value obtained by measuring 10 times. In addition, the thickness of each film layer which comprises a sheet | seat material can be measured with the optical film thickness measuring device corresponding to a known multilayer film.
