Description

  The present invention relates to an individual package of absorbent articles in which the absorbent articles are individually packaged using a packaging sheet.

  A technique is known in which an absorbent article such as a sanitary napkin is scented to change the mood and relax by the fragrance and mask the odor generated from the used absorbent article. For example, an absorbent article having a composition containing a water-activated encapsulated fragrance, an odor-inhibiting substance such as zeolite, and a liquid absorbing substance such as an absorption gelling substance has been proposed (see Patent Document 1). This absorbent article generates a pleasant scent signal during use, minimizing the odor generated from body fluids and notifying that the odor has been removed. The moisture-activated encapsulated fragrance releases the fragrance when swollen in water, and specific examples thereof include cyclodextrin, fragrance packaging complex, matrix fragrance microcapsule and the like.

  In addition, a fragrance filling and releasing agent such as a microcapsule is included in the adhesive for fixing underwear applied to the outer surface of the back sheet of the absorbent article, and the fragrance is used when the absorbent article is used, in use, or discarded. Absorbent articles are also proposed in which is released (see Patent Document 2).

Japanese National Patent Publication No. 8-508423 Japanese National Patent Publication No. 11-506690

In each of the aforementioned absorbent articles, since the article itself is scented, the fragrance is released during use of the article. Therefore, at the time of disposal after use, which is a scene in which the odor generated due to body fluids is most worrisome, the fragrance becomes weak and the odor cannot be sufficiently masked.
Further, depending on the type of the fragrance, the fragrance component may be absorbed by the superabsorbent polymer contained in the article. The reason for this is that the main chain structure and substituents of the superabsorbent polymer often have a high affinity with the fragrance component, and the fragrance component is easily absorbed. Furthermore, depending on the type of the fragrance, the substituent in the superabsorbent polymer may be covered with the fragrance component, which may reduce the absorption performance of the polymer.
Moreover, the absorbent article may contain a deodorant for adsorbing and absorbing odors generated from body fluids, and depending on the type of perfume, the deodorant performance of the deodorant may be reduced. There is also. In addition, when the absorbent article itself is scented, the scent is released to the outside of the clothes while the article is worn, and it is easy for others to notice that the absorbent article is worn.

  Accordingly, an object of the present invention is to provide an absorbent article packaging sheet and an absorbent article individual package that can eliminate the various disadvantages of the prior art.

  The present invention includes an absorbent article having an adhesive portion, a release sheet that covers the adhesive portion, and a packaging sheet that packages the absorbent article in a state where the adhesive portion is covered by the release sheet. The object is achieved by providing an individual package for absorbent articles, wherein the release sheet is scented.

The present invention also includes an absorbent article having an adhesive part, a release sheet covering the adhesive part, and a packaging sheet packaging the absorbent article in a state where the adhesive part is covered with the release sheet. A method for producing a perfume release sheet by applying a fragrance to the release sheet in an individual package of absorbent articles having
The release sheet is passed between the rolls in a state in which the perfume is adhered to the circumferential surface of one of the pair of rolls rotating in opposite directions so as to be linear along the circumferential direction of the roll. The present invention provides a method for producing a perfumed release sheet in which perfume adhering linearly to the peripheral surface of the roll is transferred to the release sheet.

Further, the present invention provides an absorbent article having an adhesive portion, a release sheet that covers the adhesive portion, and a packaging sheet that packages the absorbent article in a state where the adhesive portion is covered with the release sheet. A device for applying a fragrance to the release sheet in an individual package of absorbent articles having a perfume release sheet,
A pair of rolls rotatable in directions opposite to each other and a discharge unit disposed in contact with or in proximity to one of the pair of rolls, the discharge unit being arranged around one of the rolls The present invention provides a perfume release sheet manufacturing apparatus capable of continuously discharging a fragrance onto a surface.

  Absorbent articles after use are usually discarded by wrapping the article in a release sheet or packaging sheet, or discarded in a sealed container at once. Odor generated from the subsequent absorbent article can be masked with the release sheet. In addition, when the packaging sheet is formed from a breathable material, the aroma is released before the individual package is opened, so that the wearer can be given a relaxed feeling before using the absorbent article. In addition, since the release sheet is scented and it is not necessary to scent the absorbent article itself, if the article contains a superabsorbent polymer or a deodorant, their performance will be reduced. Is prevented. Furthermore, since the aroma is transferred from the absorbent article itself and only a weak fragrance is released, it is difficult for others to notice that the article is worn.

  The present invention will be described below based on preferred embodiments with reference to the drawings. FIG. 1 shows a perspective view of one embodiment of the present invention. The embodiment shown in FIG. 1 relates to an individual package 30 in which a release sheet 40 and a packaging sheet 10 are integrated with a hot-melt adhesive and the panty liner 20 is individually packaged (individual packaging).

As shown in FIG. 4, the panty liner 20 has a vertically long shape, and has an adhesive portion 21 for fixing to the shorts on one side (non-skin contact surface) directed to the shorts side when worn. is doing. The release sheet 40 has the same external shape as that of the panty liner 20 in plan view, and is laminated on the non-skin contact surface side of the panty liner 20 to cover the adhesive portion 21. The panty liner 20 and the release sheet 40 are integrated so as to be separable via the adhesive portion 21.
In the individual package 30, the panty liner 20 in a state in which the adhesive portion 21 is covered with the release sheet 40 is placed on the vertically long rectangular packaging sheet 10 with the release sheet 40 facing the packaging sheet 10 side. These have a structure in which the panty liner 20 is integrally formed and folded in three along a folding line extending in the width direction of the packaging sheet 10. The release sheet 40 is usually joined to the packaging sheet 10 on the outside via an adhesive or an adhesive.
And the individual packaging state is maintained by sealing the sealing part 31 of the right-and-left both sides edge of the packaging sheet 10. FIG. One end portion 10 a of the packaging sheet 10 is an opening portion 32 of the individual package 30. A tape tab 33 is detachably attached to the unsealed portion 32 so as to straddle the end portion 10a. In the opening part 32, the adhesive 34 is coated linearly along the edge part 10a of the packaging sheet. And the packaging sheets 10 which oppose in the opening part 32 are joined by the adhesive 34. FIG.

  The panty liner 20 has the same structure as a conventionally known napkin. The panty liner 20 includes a top sheet located on the side close to the wearer's skin and a back sheet located on the far side. A liquid-retaining absorber may be interposed between the two sheets. As the top sheet, a sheet material having liquid permeability such as various nonwoven fabrics or apertured films is used. As the back sheet, a water-repellent or liquid-impermeable sheet material is used. Examples of the sheet material used as the back sheet include a synthetic resin film that does not allow liquid to permeate, a non-woven fabric having water repellency, and a composite material thereof. The back sheet may have water vapor permeability. As the absorbent body, for example, a laminated fiber containing fluff pulp and a superabsorbent polymer, a polymer sheet in which the superabsorbent polymer is held and fixed in absorbent paper, and the like are used. Various deodorizers may be contained in the absorber. An adhesive is applied to the outer surface of the back sheet of the panty liner 20, and the adhesive portion 21 for fixing the panty liner 20 to the underwear is formed.

  The packaging sheet 10 is made of various sheet materials and has an inner surface and an outer surface. A release sheet 40 is provided on the inner surface of the packaging sheet 10 and is a surface on which the panty liner 20 is placed. The outer surface of the packaging sheet 10 is a surface that forms the outer surface of the individual package 30 when the panty liner 20 is individually packaged by the packaging sheet 10 to form the individual package 30.

  The release sheet 40 is scented. On the other hand, the panty liner 20 does not need to be scented. The panty liner 20 imparts a different scent at the time of carrying and actual use, and may be perfumed from the viewpoint of enhancing the masking effect. However, the panty liner 20 perfume the release sheet 40 on the inner surface of the packaging sheet 10. From the viewpoint of prominent effects, it is preferable that the panty liner 20 is not scented.

  The panty liner 20 is composed of a top sheet and a back sheet, but when it is scented into a liquid permeable sheet material such as various nonwoven fabrics or perforated films, the scent retention is low and insufficient. There is a concern that the binding force between the top sheet and the back sheet may be weakened by the fragrance component, and it is not necessary that the panty liner 20 is scented. Further, when the back sheet is made of a breathable material, there is a concern that the fragrance component may reduce the adhesive strength of the adhesive applied to fix the panty liner 20 to the underwear on the outer surface of the back sheet.

  There is no particular limitation on the fragrance component used for the fragrance of the release sheet 40, and a conventionally known fragrance component can be used without any particular limitation. In terms of easy impregnation of the fiber material, a liquid material is preferable.

  As the fragrance component, those similar to those conventionally used in the art can be used. The fragrance component has a high volatility with a boiling point of about 250 ° C. or less, or a boiling point of about 250 to about A medium-volatile one at 300 ° C. is preferably used. Examples of highly volatile perfume ingredients include anisole, benzaldehyde, benzyl acetate, benzyl alcohol, benzyl formate, isobornyl acetate, citronellal, citronellol, citronellyl acetate, paracymene, decanal, dihydrolinalol, dihydromyrcenol, dimethylphenylcarbinol, eucalyptus Putol, l-carvone, geranial, geraniol, geranyl acetate, geranyl nitrile, nerol, neryl acetate, nonyl acetate, linalool, linalyl acetate, phenylethyl alcohol, α-pinene, β-pinene, γ-pinene, α-ionone, Examples thereof include β-ionone, γ-ionone, α-terpineol, β-terpineol, terpinyl acetate, tentarome and the like. Examples of medium volatile perfume ingredients include amylcinnamaldehyde, methyl dihydrojasmonate, isoamyl salicylate, β-caryophyllene, cedrene, cedryl methyl ether, cinnamon alcohol, coumarin, dimethylbenzylcarbinyl acetate, ethyl vanillin, eugenol, isoeugenol. Γ-methyl ionone, heliotropin, hexyl salicylate, cis-3-hexenyl salicylate, phenylhexanol, vanillin, pentalide and the like.

  In addition to the above-described fragrance components, a fragrance composition containing a fragrance having a green herbal-like fragrance can also be used. The fragrance | flavor here refers to the single fragrance | flavor raw material represented by the A group and B group mentioned later. In addition, the fragrance composition is a combination of a single fragrance material, or a fragrance material composed of a plurality of fragrances such as natural essential oil or a blended base, and includes those diluted and adjusted with a solvent. By using a fragrance composition containing a fragrance having a green herbal-like fragrance, the action of the green herbal-like fragrance produced from the fragrance can cause physical irritation, particularly mental discomfort among menstrual symptoms. It can be relaxed safely and easily without giving or depending on oral administration. In addition, a comfortable feeling can be obtained.

  The green herbal-like fragrance is an incense tone including a green-like fragrance (green note) or a herbal-like fragrance (herbal note). Green-like aroma means a refreshing scent of grass and young leaves. Herbal-like fragrance (herbal note) is a natural and herb-like fragrance that uses herbs.

  The green herbal-like fragrance composition comprises cis-3-hexenol, cis-3-hexenyl formate, cis-3-hexenyl acetate, cis-3-hexenyl propionate, cis-3-hexenyl butyrate, trans-2-hexenal, Trans-2-hexenyl acetate, hexyl acetate, styryl acetate, 2-methyl-3- (3,4-methylenedioxyphenyl) -propanal (IFF company name, heional), 3 (4)-(5-ethylbicyclo [ 2,2,1] heptyl-2) -cyclohexanol, allyl 2-pentyloxyglycolate (IFF company name, allyl amyl glycolate), 4-methyl-3-decen-5-ol (Givaudan company name, Undecabertool) ), Hexylaldehyde, 2,4-dimethyl-3-cyclohexenylcarboxyaldehyde (IFF name, Toripuraru) and the group consisting of phenyl acetaldehyde (hereinafter, this group of group A) preferably contains one or more flavoring agents selected from. Commercial products can also be used as these fragrances. For example, a fragrance comprising a mixture mainly composed of 3 (4)-(5-ethylbicyclo [2,2,1] heptyl-2) -cyclohexanol is commercially available from Kao Corporation under the trade name Magnol. Yes. The fragrance | flavor contained in A group mainly produces a green-like aroma.

  The green herbal-like fragrance composition further comprises 1-menthol, 1,8-cineole, methyl salicylate, citronellal, camphor, borneol, isobornyl acetate, tarpinyl acetate, eugenol, anethole, It is preferable to contain one or more fragrances selected from the group consisting of 4-methoxybenzyl alcohol and estragole (hereinafter this group is referred to as Group B). The fragrance | flavor contained in B group mainly produces a herbal-like fragrance.

  The group A fragrance is preferably contained in the fragrance composition in an amount of 0.5 to 30% by weight, particularly 1 to 20% by weight. The group B fragrance is preferably contained in the fragrance composition in an amount of 1 to 30% by weight, particularly 5 to 20% by weight.

  The group A and group B fragrances are prepared, for example, with a suitable solvent to form a fragrance composition. Examples of the solvent include glycerin, propylene glycol, dipropylene glycol, isopropyl myristate, triethyl citrate, 1,3-butylene glycol, polyethylene glycol, and ethanol.

  The amount of the fragrance composition may be an amount that provides a sufficiently psychologically positive effect, and preferably 0.3 to 100 mg per panty liner, more preferably, depending on the size of the panty liner 20. May be appropriately selected from the range of 0.3 to 20 mg, more preferably 0.3 to 5 mg. By setting the amount of the fragrance composition to be contained within such a range, the odor and feeling of use of the fragrance composition itself are not excessive, and the effect of alleviating discomfort can be made sufficient.

  In general, the used panty liner 20 is discarded by being wrapped in a packaging sheet 10 packaging the panty liner 20 to be newly used and a release sheet 40 on the inner surface of the packaging sheet 10. Therefore, since the release sheet 40 on the inner surface of the packaging sheet 10 is scented, the odor generated from the panty liner 20 after use is masked by the scented packaging sheet. As a result, the used panty liner 20 can be discarded without causing discomfort caused by odor.

  Not the panty liner 20 but the outer surface of the release sheet 40 on the inner surface of the packaging sheet 10 that individually packages it is scented so that the release layer of the release sheet prevents permeation of the fragrance component and is included in the napkin. There is also an advantage that the performance of the superabsorbent polymer and the deodorant is not impaired by the fragrance component. In particular, since the surface that should be the outer surface in the state in which the panty liner 20 is packaged is scented, the contact between the fragrance component and the panty liner 20 can be cut off, so the performance of the superabsorbent polymer and the deodorant Reduction can be prevented more effectively.

  Since the contact between the fragrance component and the panty liner 20 is cut off, only a weak scent of a moving scent is released from the panty liner 20 itself. Therefore, the wearer of the panty liner 20 has an additional advantage that it is difficult for others to notice that the panty liner 20 is worn.

As for release sheet 40, it is preferred that the surface side on the opposite side to the surface which coats adhesion part 21 is scented. That is, it is preferable to be performed on the outer surface of the release sheet 40 on the inner surface of the packaging sheet 10, that is, on the non-release sheet surface side. 2A to 2C show specific examples in which the outer surface of the release sheet 40 is scented.
The release sheet 40 shown to Fig.2 (a) is comprised from the laminated body of the film 11 made from a synthetic resin, and the fiber layer 12 laminated | stacked on the one surface of this film. The surface of the film 11 is peeled off. In the release sheet 40, the surface on the fiber layer 12 side is a surface that should be the outer surface in a state where the panty liner 20 is packaged. And this fiber layer 12 is scented. For example, it can perfume by impregnating the fiber layer 12 with the liquid containing a fragrance | flavor component.

  As the fiber layer 12, paper, nonwoven fabric, or the like can be used. Further, the fiber layer 12 can be formed on one surface of the film 11 by electrostatically flocking fibers. Considering ease of production, texture, economy, and the like, the fiber layer 12 is preferably made of paper, and it is preferable to form a release layer or a direct release layer after the lamination process. When the fiber layer 12 is made of paper, the use of fine paper improves the finish when printing on the fiber layer 12, and the fragrance component can be successfully applied to the fiber layer 12. To preferred. In the case where the fiber layer 12 is a release sheet formed from paper, in general, treatment with a sizing agent is often performed so that ink for printing or the like does not bleed. Diffusion of the layer is suppressed.

  As said sizing agent, synthetic resins, such as polyvinyl acetate and polyethylene, can be used, for example. The amount of the sizing agent used is 0.01 to 3% by weight, particularly 0.05 to 1% by weight, based on the weight of the fiber layer 12 before the sizing is applied. This is preferable in that it can be successfully printed on the fiber layer 12 and the fragrance component can be applied while preventing bleeding and diffusion of the fragrance component.

  The release sheet 40 shown in FIG. 2B is subjected to a release process after the film 11 and the fiber layer 12 are laminated. For the purpose of displaying the product name of the individual packaging 30 or for the purpose of increasing the commercial value of the individual packaging 30, a print 13 made of characters, figures, symbols, and patterns is provided on one surface of the fiber layer 12 or a part thereof. It has been subjected. In the release sheet 40, the printing surface is a surface that should be the outer surface in a state where the panty liner 20 is packaged.

  The release sheet 40 shown in FIG. 2C has a multilayer structure. The release sheet 40 includes a synthetic resin outer layer 14 and a synthetic resin inner layer 15 of a type different from the synthetic resin of the outer layer 14. A release layer 16 is formed on the inner surface of the inner layer 15. And the fragrance | flavor component is kneaded in the synthetic resin of the outer layer 14 which makes the outer surface of the peeling sheet 40. FIG. The inner layer 15 functions as a blocking layer for preventing the fragrance component kneaded in the synthetic resin of the outer layer 14 from bleeding out toward the inside of the release sheet 40. The release layer 16 has a function of making the pressure-sensitive adhesive applied to the outer surface of the back sheet of the panty liner 20 peelable from the release sheet 40. According to the release sheet 40 shown in FIG. 2 (c), the fragrance is released to the outside by the fragrance component kneaded in the synthetic resin of the outer layer 14. Further, since the inner layer 15 serves as a fragrance component blocking layer, the fragrance does not move to the panty liner 20.

  In the release sheet 40 shown in FIGS. 2 (a) to 2 (c), the perfume component is sealed in a microcapsule so that the individual package 30 is held in the hand or the individual package 30 is opened. A fragrance can be released for the first time. As a result, effective perfume can be performed with the minimum amount of the perfume ingredient used. For example, in the release sheet 40 shown in FIG. 2 (a), as shown in FIG. 3 which is an enlarged view of the fiber layer 12 in the same figure, the microcapsule 17 enclosing the fragrance component is supported in the fiber layer 12. Keep it. When the individual package 30 is taken out of the packaging pack or when the individual package 30 is opened, the microcapsule 17 is caused by the force of the hand gripping the individual package 30 or the frictional force with the packaging pack. External force is applied to this, and this is torn. As a result, the fragrance component enclosed in the microcapsule 17 is released to the outside for the first time. The same applies to FIGS. 2B and 2C. In FIG. 2B, a microcapsule in which a fragrance component is encapsulated may be blended in the printing ink. In FIG.2 (c), the microcapsule which enclosed the fragrance | flavor component should just be kneaded in a synthetic resin.

As the release sheet, paper, non-woven fabric, woven fabric, knitted fabric, film, or a laminate of these can be used as a base sheet, and a known release treatment can be used.
As a material for the packaging sheet, paper, non-woven fabric, woven fabric, knitted fabric, film, or a laminate thereof can be used.

  In many cases, the fragrance contains an oil component. Therefore, in the individual package 30 shown in FIG. 1, when the fragrance is applied over the entire area of the release sheet 40, the pressure-sensitive adhesive (hot) used for integration with the packaging sheet is caused by the oil component contained in the fragrance. Such as melt pressure-sensitive adhesives) or adhesive properties such as adhesives, and when the packaging sheet and release sheet cannot be fixed, or when the pressure-sensitive adhesive is exposed on the surface of the packaging sheet and individual packages are bonded together There is. Therefore, in order to ensure the fixation of the packaging sheet and the release sheet, it is preferable that the fixing portion is not perfumed.

As described above, as a form in which the fixing portion 41 is not scented, it is preferable that the scent is added except for the position corresponding to the fixing portion, specifically, in a streak shape.
In the example shown in FIG. 4, the release sheet 40 and the packaging sheet 10 are partially joined by an adhesive or the like at a plurality of locations separated in the longitudinal direction of the panty liner 20. Further, in the case of a release sheet using paper as the fiber layer 12, the oil component can be prevented from diffusing in the sheet by the sizing agent. An effect can be obtained. Thereby, it is possible to avoid the disadvantage that the adhesive properties of the adhesive such as hot melt adhesive due to the oil component are lowered. When a release sheet that has not been sized is used, embossing can be performed. As a result, the embossed portion becomes a barrier portion that hinders the transfer of the oil component, and the oil component does not easily reach the seal portion 31.

  As shown in FIG. 4, as a method for perfume the release sheet 40, for example, a method using a coating apparatus shown in FIG. The coating apparatus 10 shown in FIG. 5 includes a pair of smooth rolls 11 and 12 arranged along the vertical direction so as to contact each other. Between the rolls 11 and 12, an original fabric 40a of the release sheet 40 is inserted. The original fabric 40a is conveyed from right to left in FIG. The rolls 11 and 12 are made of metal or rubber, for example. The material of the rolls 11 and 12 may be the same or different. Further, the diameters of the rolls 11 and 12 may be the same or different. The rolls 11 and 12 are rotatable in the directions indicated by arrows in FIG. Of the two rolls 11 and 12, a plurality of fragrance discharge portions 13 are arranged above the roll 11 located on the upper side. The discharge units 13 are arranged at equal intervals along the axis of the roll 11. The discharge unit 13 is located on the central axis of the roll 11. The discharge unit 13 is connected to a perfume storage tank (not shown) through a pump (not shown). The discharge unit 13 has a structure capable of continuously discharging a small amount of fragrance. For this purpose, the discharge part 13 has the shape of a syringe. The discharge port 13 a of the discharge unit 13 is in contact with or close to the surface of the roll 11. A slitter 14 is disposed at a position downstream of the rolls 11 and 12 with respect to the conveying direction of the raw sheet 40 a of the release sheet 40. The slitter 14 is comprised from a circular cutter. The original fabric 40a is cut at a predetermined interval by the slitter 14 across its width direction.

  The method of applying a fragrance using the coating apparatus shown in FIG. 5 is as follows. The fragrance | flavor discharged from the discharge outlet 13a of the discharge part 13 adheres to the surrounding surface of the roll 11 among the rolls 11 and 12 which rotate in the mutually opposite direction in the state which contacted. Since the roll 11 rotates in the direction indicated by the arrow in FIG. 5, the trajectory 15 drawn by the fragrance attached to the peripheral surface of the roll 11 is a linear one along the circumferential direction of the roll 11. A plurality of the trajectories 15 are formed along the axial direction of the roll 11. As a result, the fragrance adheres to the circumferential surface of the roll 11 in a streak pattern along the circumferential direction.

  The fragrance | flavor adhering to a stripe form is transcribe | transferred by the raw fabric 40a of the peeling sheet 40 which passes between the rolls 11 and 12. As a result, a fragrance | flavor is apply | coated to the original fabric 40a in the shape of several stripes along the conveyance direction. The width of the applied fragrance can be about 1 mm in the thinnest case. Thereafter, the original fabric 40a passes between the rolls 11 and 12, and is cut by the slitter 14 at a predetermined interval in the width direction. As a result, the raw fabric 40a becomes a narrow long strip-shaped body 40b. A rectangular release sheet 40 is obtained by further cutting the long belt-like body 40b at a predetermined interval in the width direction.

  According to the above method, even if the inevitably fluctuating amount of the fragrance discharged from the discharge unit 13 occurs, the amount of the fragrance attached to the peripheral surface of the roll 11 during the rotation of the roll 11 To be homogenized. Accordingly, the fragrance is transferred to the original fabric 40a of the release sheet 40 in a uniform amount. For example, even if the amount of the fragrance discharged from the discharge unit 13 changes over time as shown in FIG. 6A due to pulsation of a pump (not shown) used for discharging the fragrance, the roll 11 When the amount of the fragrance attached on the peripheral surface of the roll 11 is made uniform during the rotation of the roll 11 and transferred to the original fabric 40a, the uniform state shown in FIG. 6B is obtained. Accordingly, the coated portion has a uniform coating width over the length direction. As apparent from the above description, this method is particularly effective when a small amount of a fragrance is applied in a narrow width or when applied at a fine pitch. This method is more effective when used in combination with the sizing agent described above.

  In addition, in the coating device 10 shown in FIG. 5, although a pair of rolls 11 and 12 are arrange | positioned along a perpendicular direction, it may replace with this and rolls 11 and 12 may be juxtaposed along a horizontal direction. Moreover, in the coating device 10, although the discharge part 13 was arranged in multiple numbers, it may replace with this and a fragrance | flavor may be discharged using the single discharge part arrange | positioned so that many discharge ports may form a row. .

  As mentioned above, although this invention was demonstrated based on the preferable embodiment, this invention is not restrict | limited to the said embodiment, A various change is possible. For example, when the packaging sheet 10 and the release sheet 40 are not integrated, and the release sheet 40 is scented, it can be applied to the entire non-release surface of the release sheet 40. Moreover, you may use in the packaging form which packed only the perfume sheet | seat and absorptive article which perfume | scented without using a packaging sheet, or the absorbent article perfume | scented to the release sheet.

  Moreover, in the peeling sheet 40 of each said embodiment, although the case where the surface which should become an outer surface in the state which packaged the panty liner 20 was mainly fragranced was demonstrated, in the individual package 30, a fragrance | flavor component May not be excessively transferred to the panty liner 20, the inner surface of the release sheet 40, that is, the surface facing the panty liner 20 may be scented.

  Moreover, in the said embodiment, although the peeling sheet 40 exists in the inner surface of the packaging sheet 10, and the panty liner 20 was used as an absorptive article packaged in the inner side, this invention is other absorptive articles, for example, physiological It is also applied to napkins and incontinence pads.
