FIG. 1 (a) and 1 (b), an adhesive layer (not shown) that bonds the base material layer 12 and the fragrance spreading layer 11 between the base material layer 12 and the fragrance spreading layer 11 ) Or other layers can be provided as appropriate. Hereinafter, each layer which comprises the sealing seal | sticker 1 of this invention is demonstrated in detail.

(Fragrance spreading layer)
The fragrance spreading layer 11 is provided on the upper surface of the base material layer 12. The fragrance spreading layer 11 contains the same fragrance as the fragrance imparted to the scented product with the sealing seal 1 attached. The fragrance contained in the fragrance spreading layer 11 is not particularly limited, and examples thereof include carnations, lavenders, beetles, gardenia, roses, jasmine and other herbs, chamomile, cinnamon, rosemary and other herbs, oranges, lemons, cherries, etc. One kind or several kinds can be selected and used from a variety of forests such as Japanese cypress, Japanese cypress, pine and fir trees.

  The fragrance-diffusing layer 11 contains the microcapsule 14 encapsulating the fragrance because it maintains the scent contained in the scented product during transportation and can effectively diffuse the fragrance when the fragrance is sampled. preferable. A consumer who wants to give a sample rubs the surface of the fragrance-diffusing layer 11 to destroy the microcapsule 14 having a fragrance, thereby generating a scent.

  The fragrance | flavor enclosed with the microcapsule 14 in the fragrance spreading layer 11 can select suitably the manufacturing method of a conventionally well-known microcapsule for the fragrance | flavor which is a compound which volatilizes and emits fragrance, for example, a coacervation method, an in situ Or an interfacial polymerization method can be used.

  The kind of wall material of the microcapsule 14 is not particularly limited. Generally, any material that can be encapsulated, such as gelatin, gum arabic, polyvinyl alcohol, ethyl cellulose, carboxymethyl cellulose, polyurethane, sodium alginate, urea / formaldehyde resin, melamine / formaldehyde resin, can be used, although it varies depending on the aromatic component. Further, the structure of the microcapsule 14 is not particularly limited, and for example, a simple mononuclear structure can be exemplified. Furthermore, the average particle diameter of the microcapsules 14 is not particularly limited, and may be, for example, 5 μm or more and 30 μm or less, preferably 12 μm or more and 20 μm or less. When the average particle size of the microcapsules 14 is less than 5 μm, it becomes impossible to include a necessary and sufficient fragrance. On the other hand, when the average particle size of the microcapsule 14 exceeds 30 μm, the wall material of the microcapsule 14 may be broken during mixing or drying in the coating solution, and the fragrance may flow out.

  The wall film of the microcapsule 14 has a thickness of 10% to 15% with respect to the average particle size, and the core material has a thickness of 85% to 90% with respect to the average particle size. It is preferable that However, if the wall film is too thin, the wall material of the microcapsule 14 may be broken during mixing or drying in the coating solution, and the fragrance may flow out. On the other hand, if the wall film is too thick, the wall material is difficult to break, and even if it is rubbed, a sufficient scent is not produced, so that there is a possibility that the sample cannot be made.

  Further, the mass ratio of the core substance of the microcapsule 14 can be adjusted according to the strength of the fragrance (sublimation), but is preferably 85% by mass or more and 90% by mass or less per mass of the microcapsule 14, 75 mass% or more and 85 mass% or less are more preferable.

The fragrance spreading layer 11 is a known printing method such as offset printing, silk screen printing, gravure printing, flexographic printing, and the like, in which a fragrance component enclosed in a microcapsule 14 is mixed with a solvent component such as ink or organic solvent. It is preferable that the coating amount is 2 g / m ² or more and 20 g / m ² or less in a dry state on the upper surface of the base material layer 12 by a method such as formation by a method. Further, two or more kinds of coating liquids using microcapsules 14 containing different fragrances can be prepared and printed separately in different regions of the base material layer 12. Furthermore, the printing layer 16 which does not contain a fragrance | flavor is printed in the area | region different from the fragrance diffused layer 11 of the upper surface of the base material layer 12, or as shown in FIG.1 (b), the fragrance diffused layer 11 and the base material layer 12 are shown. It can also be formed between. Printing can clearly indicate the presence of the sealing sticker 1 to the consumer by displaying a color or a pattern on the surface of the sealing sticker 1. As shown in the package or FIG. 3, by displaying an explanatory note or the like such as “I smell when I rub” on the sealing sticker 1, it can be clearly shown to the consumer that the sealing sticker 1 emits a fragrance. When an external force is applied by printing of the fragrance spreading layer 11 or the formation of the printing layer 16, the appearance of the sealing seal 1 changes due to distortion or the like, so that it becomes a trace of fraud or the like and has a function of improving its visibility.

  In addition, the thickness of the fragrance spreading layer 11 is preferably 5 μm or more and 40 μm or less from the viewpoint of not destroying the microcapsule 14 when the fragrance spreading layer 11 is applied or printed.

  As shown in FIG. 1B, it is preferable to provide a protective layer 15 on the upper surface of the fragrance spreading layer 11 from the viewpoint of protecting the fragrance spreading layer 11 from rubbing during handling. The protective layer 15 can be formed by, for example, laminating a peelable film on the fragrance spreading layer 11 or coating a resin component on the fragrance spreading layer 11.

  Examples of the base material for the peelable protective layer 15 include resin films such as cellophane, polyester, polyethylene, polypropylene, polyvinyl chloride, and polyamide, paper such as condenser paper and paraffin paper, and any of these. May be combined.

As the resin component forming the protective layer 15, urethane resin, polyethylene resin, polystyrene resin, acrylic resin, styrene-butadiene block copolymer, melamine resin, epoxy resin, and the like can be used as appropriate. Moreover, you may contain a pigment, dye, a lame, etc. The method for forming the protective layer 15 is, for example, a coating liquid prepared by blending and adjusting a resin component and an additive such as a solvent by a conventionally known method such as gravure direct coating, gravure reverse coating, knife coating, air coating, roll coating, etc. It can be formed with a coating amount in a dry state of ² g / m ² or more and 10 g / m ² or less.

(Base material layer)
The base material layer 12 is not damaged by transportation, display, handling, etc., is attached to an object to be sealed, peels off the attached seal 1 and is broken and opened so that there is no problem in handling. As such a base sheet, a base sheet generally used for sealing sealing, such as paper such as art paper or fine paper, synthetic paper, non-woven fabric, resin sheet, etc. It can be used without any particular restrictions. Moreover, although the thickness of the base material layer 12 can be suitably changed according to a material so that the intensity | strength and a softness | flexibility may become appropriate, 20 micrometers or more and 150 micrometers or less are preferable.

(Adhesive layer)
The pressure-sensitive adhesive layer 13 serves to attach the sealing seal 1 to the surface of the opening / closing part of a scented product containing the fragrance that is to be sealed. As the material of the pressure-sensitive adhesive layer 13, a normal adhesive such as various known pressure-sensitive adhesives such as an acrylic pressure-sensitive adhesive, a polyester-based pressure-sensitive adhesive, and a urethane-based pressure-sensitive adhesive can be used without particular limitation.
