 BEST MODE FOR CARRYING OUT THE INVENTION

 [0019] Next, the present invention will be described in more detail with reference to embodiments.

 FIG. 1 shows a developed state of the tissue carton Tc in the embodiment when the sheet is tissue paper and the storage body is a paper storage box.

 [0020] The tissue carton Tc has a central portion configured as a bottom surface 1, a side surface 2, a top surface 3, and a side surface 4. The bottom surface 1, the side surface 2, the top surface 3, and the side surface 4 are respectively on the side edges in the longitudinal direction. End face pieces 11 and 11, side face face pieces 12 and 12, upper face side face pieces 13 and 13, and side face face pieces 14 and 14 are connected. An adhesive flap 5 is connected to the bottom surface 1. Further, an opening lid portion 20 defined by perforations for taking out tissue paper is formed on the upper surface 3.

 [0021] The strong tissue carton Tc is assembled in a rectangular parallelepiped shape with a hot melt adhesive as shown in Fig. 2 in a state where a bundle of tissue paper P is housed inside.

[0022] Also, as shown in FIG. 6, the entire opening lid portion 20 is covered widely on the back surface side of the upper surface 3 in advance. A plastic sheet 30 made of polyethylene, polypropylene, polyethylene terephthalate, polystyrene or the like as a storage sheet material is bonded and fixed to the back surface of the upper surface 3 with a hot melt adhesive 33 or the like. As the storage sheet material described above, a non-woven fabric obtained by mixing these sheet materials, for example, a non-woven fabric obtained by mixing polyethylene and polypropylene, can be used. From the aspect aspect, an air-through non-woven fabric, a melt-processed non-woven fabric, a point bond can be used. Nonwoven fabrics, spunbond nonwoven fabrics and the like can be used. Synthetic paper is also possible, and as synthetic fiber or chemical fiber to be mixed, rayon, acetate and vinyl acetate are suitable, and polyethylene, polypropylene, polyester and the like can also be used.

 [0023] As the adhesive 33, a hot melt can be used, and in addition, a so-called cold glue such as a vinyl acetate adhesive or an acrylic adhesive can also be used.

 [0024] The plastic sheet 30 has a length shorter than the length of the opening lid portion 20 as shown in FIG. 3, substantially the same as the length of the opening lid portion 20 as shown in FIG. 4, and as shown in FIG. A slit 31 as a take-out port for taking out the unit tissue paper P is formed in a form such as longer than the length of the portion 20.

 [0025] The structure itself of the storage box is basically known.

 [0026] However, in the present invention, the microcapsule support layer 40 that encloses the fragrance component is provided in at least a portion of the plastic sheet 30 that is rubbed when the tissue paper P is taken out.

 [0027] Although the microcapsule support layer 40 can be directly formed on the surface of the plastic sheet 30 by coating or the like, it is preferable that the microsheets 32A and 32B are formed on the surface of the plastic sheet 30 by corona discharge treatment. It is desirable to improve the adhesion of the capsule carrier layer 40.

[0028] It is preferable that the unevenness difference of the surface (particularly the polyethylene filament surface) where the unevenness 32A, 32B is formed by vigorous corona discharge treatment is 10 to 1000 nm. If it exceeds lOOOnm, the strength of the plastic sheet 30 becomes weak, and there is a risk that the operability when the plastic sheet 30 is bonded and fixed to the back side of the top surface 3 of the tissue carton Tc may be hindered. On the other hand, if it is less than lOnm, problems such as dropout that the adhesion of the microcapsule support layer 40 is poor occur. It becomes easy. Furthermore, the “wetting tension” (JIS K 6768: 1999) of the irregularities 32A and 32B is preferably 1 to 50 mNZm. If it exceeds 50 mNZm, the transparency will be hindered and the appearance will deteriorate, and if it is less than lmNZm, the adhesiveness will deteriorate.

 [0029] As the formation form of the microcapsule support layer 40, when the formation region is shown by cross hatching in the drawing, the entire plastic sheet 30 as shown in FIG. 7 and both sides of the slit 31 of the plastic sheet 30 as shown in FIG. Only the portion can be formed in a strip shape extending in a direction orthogonal to the slit 31 as shown in FIG. 9 or a lattice shape as shown in FIG.

 That is, when the tissue paper P is taken out and the tissue paper is rubbed into contact with the micro force capsule and the micro capsule force perfume component is volatilized, the formation form of the microphone mouth capsule support layer 40 is limited. Not.

 [0031] The fragrance that can be used in the present invention is not particularly limited, but specific examples include, for example, Ryusen Incense, Benzo, Kaigo Incense, Sacred Cat Incense, Clove Oil, Galvanam, Jasmine Absolute, Natural flavors such as Labanum, Mate Tea, Merilot, Mimosa, Musta Tonkin, Myrrh, Oak Moss or Moss de Chine, Milk Incense, Scotch Incense, Oris, Bachi Lily, Rosemary Oil, Sandalwood Oil, Vechi Bar Oil, Violet Leaf Absolute, High Alcohol, Various synthetic fragrances such as aldehyde, benzaldehyde, benzoic acid, key cinnamate, key aldehyde, key skin alcohol, coumarin, ester, indole, ketone, salicylic acid and related compounds, terpenoids, vanillin, etc. Mention may be made of two or more mixtures. Commercial products can also be used.

 [0032] A known method can be used for producing a microcapsule enclosing such a fragrance, and is not particularly limited. Specifically, the core material is a fragrance, and for example, a melamine or urea formalin resin, which is a capsule wall material, is formed by an in situ method using a partially hydrolyzed product of styrene maleic anhydride and a prepolymer of melamine or urea and formalin. Then, a microcapsule enclosing a fragrance is produced. A microcapsule enclosing a perfume produced in an aqueous system can be used as it is.

 [0033] The particle size of the microcapsules is not limited, but for example, an average particle size of 0.3 to 50 µm, particularly 3 to 20 m is desirable.

[0034] The method for forming the microcapsule support layer 40 includes roll transfer coating and spray coating. -

 Appropriate methods such as 8 can be adopted. In particular, gravure coating of the coating liquid is desirable.

As the coating solution, it is desirable to use a binder, for example, starch, PVA, urethane resin, and acrylic resin. For example, the microcapsules dispersed in the binder in an amount of, for example, 1 to 20% by weight are preferably applied in a solid amount of, for example, 2.3 to 23 gZm ² . A dispersing agent such as a solvent can be appropriately used in the coating solution.

 [0036] (Production method)

 Many of the manufacturing methods in the present invention have already been described. However, when using tissue paper as an example, the above-described storage is performed at least before storing a bundle of tissue paper in a storage box (tissue carton Tc). A sheet material, specifically, a plastic sheet 30 is fixed to the back side of the storage box.

 That is, at the stage of obtaining the tissue carton Tc shown in FIG. 1, the plastic sheet 30 on which the microcapsule carrying layer 40 is formed is fixed.

 [0038] Then, the flap 5 is joined to the side surface 4 with a hot melt adhesive or the like to complete the molding, and is brought into the production line.

 [0039] In the production line, the folded folded tissue carton Tc shown in Fig. 11 is sucked from above or below, and the Z or lateral force is also pushed to open both sides in the longitudinal direction as shown in Fig. 12. Each end piece 11, 12, 13, 14 is bent approximately 90 degrees outward. Thereafter, as shown in FIG. 13, the tissue paper bundle Tp laminated by a known inter-holder is accommodated in the tissue carton Tc from the side opening. This accommodation can be performed, for example, by a conventionally known method in which a rectangular tube-shaped tissue carton Tc and a tissue paper bundle Tp are run side by side, and the side paper opening force is pushed into the tissue carton Tc to accommodate the tissue paper Τp. it can.
