Description

Individual package of absorbent article and method of manufacturing individual package of absorbent article

The present invention relates to an individual package of an absorbent article which is obtained by individually packaging an absorbent article using a packaging sheet.

A technique of imparting a fragrance to an absorbent article such as a sanitary napkin, and using the aroma to improve the sense of mood or relax, and masking the odor generated by the absorbent article used by itself is known. For example, there has been proposed an absorbent article comprising a composition comprising a substance which inhibits odor such as a water-activated encapsulating fragrance, a zeolite, and a liquid absorbing substance such as a gelling substance (refer to WO94/22500). The absorbent article minimizes the odor generated by the body fluid and generates a fresh aroma signal indicating that the odor has been removed during use. The water is activated by encapsulation of the fragrance, and the fragrance is released when it is swollen in water. Specific examples thereof include a cyclodextrin, a fragrance package complex, and a matrix fragrance microcapsule.

Further, there is also proposed an absorbent article comprising a fragrance-filling agent such as a microcapsule contained in an adhesive for fixing a panty, the adhesive being disposed on an outer surface of the inner sheet of the absorbent article, thereby being absorbent Aroma is emitted when the article is in use, during use, and when discarded (see WO97/25955).

In each of the above absorbent articles, since the article itself is imparted with aroma, the aroma can be released during use of the article. Therefore, when the odor is most intentionally caused by the body fluid, that is, when discarded after use, the aroma is weak and the odor cannot be sufficiently masked.

Further, depending on the type of the flavor, the flavor component may be absorbed by the superabsorbent polymer contained in the article. The reason for this is that the main chain structure or the substituent of the superabsorbent polymer generally has a high affinity with the perfume component, so that the perfume component is easily absorbed. Further, depending on the type of the fragrance, the substituent in the superabsorbent polymer may also be covered by the fragrance component, thereby lowering the absorption properties of the polymer.

Also, absorbent articles sometimes contain adsorption. The deodorant that absorbs the odor generated by the body fluid may have a deodorizing performance of the deodorant depending on the type of the fragrance. Further, if the absorbent article itself is imparted with a fragrance, the fragrance overflows to the outside of the garment during the wearing of the article, and thus it is easy for others to find that the absorbent article is worn.

Accordingly, it is an object of the present invention to provide a packaging sheet for an absorbent article and an individual packaging body for an absorbent article which solve various disadvantages of the prior art described above.

The present invention achieves the above object by providing an individual package of an absorbent article, wherein the individual package of the absorbent article is characterized in that it comprises an absorbent article having an adhesive portion and a peeling off the adhesive portion. The sheet and the packaging sheet are the absorbent articles in a state in which the adhesive portion has been covered by the release sheet, wherein the release sheet is imparted with a fragrance.

Moreover, the present invention provides a method for producing a release sheet for imparting a fragrance by applying a fragrance to one of the individual packages of an absorbent article to produce a release sheet for imparting a fragrance, the absorbent article The individual packaging system includes an absorbent article having an adhesive portion, a release sheet covering the adhesive portion, and a packaging sheet for packaging the absorbent article in a state in which the adhesive portion has been covered by the release sheet; Aligning one of the pair of rollers on the circumferential surface of one of the rollers to adhere the fragrance in a line shape along the circumferential direction of the roller. In this state, the release sheet is passed between the rollers, and the roller is The perfume adhered in a line on the circumferential surface is transferred onto the release sheet.

Further, the present invention provides a manufacturing apparatus for a release sheet for imparting a fragrance by applying a fragrance to one of the individual packages of an absorbent article to produce a release sheet for imparting a fragrance, the absorbent article The individual packaging system includes an absorbent article having an adhesive portion, a release sheet covering the adhesive portion, and a packaging sheet, the absorbent article in a state in which the adhesive portion has been covered by the release sheet; A direction-rotating pair of rollers and a discharge portion disposed in contact with or close to one of the pair of rollers, the discharge portion continuously ejecting the fragrance to a circumferential surface of one of the rollers.

Hereinafter, the preferred embodiments of the present invention will be described with reference to the drawings. Fig. 1 is a perspective view showing an embodiment of the present invention. The embodiment shown in Fig. 1 is associated with an individual package 30 which integrates the release sheet 40 with the packaging sheet 10 by means of a hot-melt adhesive and has a panty liner 20 individually. Packaged.

As shown in Fig. 4, the sanitary pad 20 has an elongated shape and has an adhesive portion 21 for fixing to the shorts on a single side (a surface not in contact with the skin) facing the shorts side when worn. The release sheet 40 has the same shape as the sanitary pad 20 as viewed in the plane direction, and is laminated on the non-skin contact surface side of the sanitary pad 20 and covers the adhesive portion 21. The sanitary pad 20 and the release sheet 40 are detachably integrated with each other via the adhesive portion 21. The individual package 30 has a structure in which the sanitary pad 20 in a state where the adhesive sheet 40 is covered with the adhesive portion 21 is placed on the side of the packaging sheet 10 so as to be placed on the longitudinally rectangular rectangular packaging sheet 10 And as a whole, the sanitary pad 20 is formed inside, and the fold line extending in the width direction of the packaging sheet 10 is folded into three. The release sheet 40 is usually joined to the packaging sheet 10 present on the outside thereof via an adhesive or an adhesive.

Further, the individual packaging state can be maintained by sealing the sealing portions 31 on the left and right side edges of the packaging sheet 10. One of the side end portions 10a of the packaging sheet 10 serves as the opening portion 32 of the individual package body 30. The band piece 33 is detachably attached to the opening portion 32 so as to straddle the end portion 10a. In the unsealing portion 32, the adhesive 34 is applied in a line shape along the end portion 10a of the packaging sheet. Further, at the unsealing portion 32, the facing packaging sheets 10 are joined to each other by the adhesive 34.

The panty liner 20 has the same structure as previously known sanitary napkins. The sanitary pad 20 has a top sheet located on the near side of the wearer's skin and an inner side sheet on the far side. A liquid retaining absorber can be disposed between the two sheets. As the surface sheet, various liquid permeable sheets such as non-woven fabrics or apertured films can be used. As the inner sheet, a water-repellent to liquid-impermeable sheet can be used. Examples of the sheet used as the inner sheet include a synthetic resin film which is impermeable to liquid, a non-woven fabric having water repellency, and the like. The inner sheet can have water vapor permeability. As the absorber, for example, a fiber body containing a fluff pulp and a superabsorbent polymer, a polymer sheet in which a superabsorbent polymer is held and fixed in an absorbent paper, or the like can be used. Various deodorants may also be contained in the absorber. An adhesive is applied to the outer surface of the inner sheet of the sanitary pad 20 to form the adhesive portion 21 for fixing the sanitary pad 20 to the undergarment.

The packaging sheet 10 contains various sheets having an inner surface and an outer surface. The inner surface of the packaging sheet 10 has a release sheet 40 which is placed on the surface of the sanitary pad 20. On the outer surface of the packaging sheet 10, when the sanitary pad 20 is individually packaged by the packaging sheet 10 to form the individual package 30, the outer surface of the individual package 30 is formed.

The release sheet 40 is imparted with a fragrance. In contrast, the sanitary pad 20 need not be given a fragrance. The sanitary pad 20 can also be imparted with a fragrance in terms of imparting different aromas during carrying and actual use, and improving the masking effect. However, the viewpoint of imparting a fragrance effect to the peeling sheet 40 on the inner surface of the packaging sheet 10 is emphasized. In particular, it is preferred that the panty liner 20 is not imparted with a fragrance.

Further, the sanitary pad 20 includes a top sheet and an inner sheet, and when a flavor is imparted to a liquid permeable sheet such as various nonwoven fabrics or apertured films constituting the same, there is a fear that the aroma retention is low. Not enough, or the bonding force between the topsheet and the inner panel is weakened according to the fragrance component, so that it is not necessary to impart a fragrance to the sanitary pad 20. Further, in the case where the inner sheet contains the air permeable material, there is also concern that the fragrance component lowers the adhesive force of the adhesive for fixing the sanitary pad 20 to the undergarment provided on the outer surface of the inner sheet.

The flavor component for imparting a fragrance to the release sheet 40 is not particularly limited, and a previously known flavor component can be used without particular limitation, but it is easily impregnated with a particulate or powder which absorbs the flavor component. Liquids are preferred in terms of paper fibers.

As the perfume component, the same perfume as the former user in the technical field can be used, and a high volatility having a boiling point of about 250 ° C or less or a boiling point of about 250 to about 300 ° C can be preferably used. Volatile. Examples of the highly volatile flavor component include anisole, benzaldehyde, benzyl acetate, benzyl alcohol, benzyl formate, isodecyl acetate, citronellal, citronellol, citronellyl acetate, and umbellifers. Paracymene, furfural, dihydrocinem, dihydromyrcenol, dimethylphenylmethanol, eucalyptol, 1-fragrant celery, geranial, geraniol, Geranyl acetate, geranyl nitrile, nerol, neryl acetate, decyl acetate, linalool, acetoacetate, phenylethyl alcohol, α-pinene, β-pinene, γ-pinene, α-violet Ketone, β-ionone, γ-ionone, α-terpineol, β-terpineol, terpineol acetate, tentarome, and the like. Examples of the medium volatile flavor component include penicillin, methyl dihydrojasmonate, isoamyl salicylate, β-caryophyllene, cedarene, cedar methyl ether, cinnamyl alcohol, coumarin, and acetic acid. Dimethylbenzyl methanol ester, ethyl vanillin, eugenol, isoeugenol, γ-methyl ionone, geranyl aldehyde, hexyl salicylate, cis-3-hexene salicylate, Phenylhexanol, vanillin, pentadecanolide, and the like.

In addition to the above perfume ingredients, a perfume composition containing a fragrance having aroma such as green herbal may also be used. The term "perfume" as used herein refers to a monomeric perfume raw material typified by Group A or Group B below. Further, the fragrance composition is a combination of the monomeric fragrance raw materials or a fragrance raw material comprising a plurality of flavors such as natural essential oils or blending bases, including dilution and adjustment by a solvent. By. By using a fragrance composition containing a fragrance having a fragrance such as green herbs, the aroma of a green herb produced from the fragrance can be utilized, without giving physical stimulation to the body, and without Oral administration, and it is safe and easy to alleviate the symptoms associated with menstruation, especially the symptoms of mental discomfort. In addition, you can also feel comfortable.

For example, the aroma of green herbs contains aroma such as green (green note) or aroma such as herbal (herbal note). The so-called aroma of green leaves refers to the refreshing fragrance of grass or young leaves. The so-called aroma of herbs (herbal notes) refers to the use of herbs (herb) to produce a herbal aroma that is characteristic of the fragrance.

For example, a green herbal flavor composition preferably contains self-cis-3-hexenol, cis-3-hexenyl formate, cis-3-hexene acetate, cis-3-hexene propionate, Cis-3-hexenyl butyrate, trans-2-hexenal, trans-2-hexenyl acetate, hexyl acetate, benzyl methyl acetate, 2-methyl-3-(3,4 -methylenedioxyphenyl)-propionaldehyde (IFF company name, new jasmine aldehyde (helional)), 3(4)-(5-ethylbicyclo[2,2,1]heptyl-2) - cyclohexanol, allyl 2-pentyloxyacetate (IFF company name, allyl amyl glycolate), 4-methyl-3-decene-5-ol (Givaudan) Company name, group of methyl ketoenol (Undeca Vertol), hexanal, 2,4-dimethyl-3-cyclohexene formaldehyde (IFF company name, Tripral) and phenylacetaldehyde (hereinafter, This group is referred to as one or two or more flavors selected from the group A. Commercially available products can also be used as the fragrances. For example, Kao Corporation sells a mixture containing the above 3(4)-(5-ethylbicyclo[2,2,1]heptyl-2)-cyclohexanol as a main component, under the trade name of Magnol. spices. The fragrance contained in group A mainly produces aroma such as green leaves.

For example, the green herbal spice composition, in addition to the above-mentioned group A fragrance, preferably further contains 1-menthol, 1,8-eucalyptol, methyl salicylate, citronellal, camphor, borneol One or two selected from the group consisting of isodecyl acetate, rosin acetate, eugenol, aniseed brain, 4-methoxybenzyl alcohol, and medicinal camphor (hereinafter, referred to as group B) The above spices. The fragrance contained in group B mainly produces aroma such as herbal medicine.

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

The fragrance of the above-mentioned group A and group B can be blended with a suitable solvent to form a fragrance composition, for example. As the solvent, for example, glycerin, propylene glycol, dipropylene glycol, isopropyl myristate, triethyl citrate, 1,3-butylene glycol, polyethylene glycol, ethanol or the like can be used.

The amount of the fragrance composition may be sufficient to obtain a psychologically positive effect, and the size of the corresponding sanitary pad 20 is preferably from 0.3 to 100 mg, and more preferably from 0.3 to 1 per sanitary pad. A suitable choice of 20 mg, more preferably in the range of 0.3 to 5 mg. By setting the amount of the flavor composition to be contained in this range, it is possible to prevent the taste of the perfume composition itself or the feeling of use from being excessive, and to sufficiently exert the effect of alleviating the unpleasant feeling.

Usually, the sanitary pad 20 after use is wrapped in a packaging sheet 10 for packaging the newly used sanitary pad 20 and a release sheet 40 on the inner surface of the packaging sheet 10 to be discarded. Therefore, by imparting a fragrance to the release sheet 40 on the inner surface of the packaging sheet 10, the odor generated from the sanitary pad 20 after use is masked by the packaging sheet to which the fragrance is imparted. As a result, the unpleasant feeling caused by the odor is not generated when the sanitary pad 20 after use is discarded.

There is also the advantage that the release layer of the release sheet can prevent the penetration of the fragrance component by the absence of the sanitary pad 20 to impart a fragrance to the outer surface of the release sheet 40 existing on the inner surface of the packaging sheet 10 which is individually packaged. The properties of the superabsorbent polymer or deodorant contained in the cotton are not impaired by the perfume ingredients. In particular, by adding a fragrance to the outer surface of the sanitary pad 20 in a state where it is packaged, the fragrance component is blocked from coming into contact with the sanitary pad 20, so that the highly absorbent polymer or deodorant can be further effectively prevented. The performance is reduced.

By blocking the contact of the aroma component with the panty liner 20, the panty liner 20 itself can only emit a weaker aroma that is stained. Therefore, there is also the additional advantage that the wearer of the sanitary pad 20 is not easily found by others to wear the sanitary pad 20.

It is preferable that the release sheet 40 is provided with a fragrance on the side opposite to the surface on which the adhesive portion 21 is coated. That is, it is preferred to impart a fragrance to the outer surface of the release sheet 40 on the inner surface of the packaging sheet 10, that is, the surface side of the non-peeling sheet. In (a) to (c) of FIG. 2, a specific example in which the fragrance is applied to the outer surface of the release sheet 40 is exemplified.

The release sheet 40 shown in Fig. 2(a) is composed of a film 11 made of a synthetic resin and a fiber layer 12 laminated on one surface of the film. The surface of the film 11 is subjected to a peeling treatment. In the peeling sheet 40, the surface on the side of the fiber layer 12 is the outer surface of the sanitary pad 20 in a state of being packaged. Moreover, the fibrous layer 12 is imparted with a fragrance. For example, the fragrance can be imparted by impregnating the fibrous layer 12 with a liquid containing a fragrance component.

As the fiber layer 12, paper, a nonwoven fabric, or the like can be used. Further, the fibers may be electrostatically implanted on one surface of the film 11 to form the fiber layer 12. In consideration of ease of manufacture, hand feeling, economy, and the like, it is preferred that the fiber layer 12 be composed of paper, and a release layer or a release layer is directly formed after the lamination treatment. In the case where the fiber layer 12 is composed of paper, it is preferable to use high-grade paper to obtain a finished product when the fiber layer 12 is printed, and to apply the perfume component to the fiber layer 12 smoothly. In the case where the fiber layer 12 is a release sheet formed of paper, the sizing treatment is usually carried out so that the ink such as printing is not smudged, and the sizing treatment can suppress the diffusion of the fragrance component into the fiber layer.

As the sizing agent, for example, a synthetic resin such as polyvinyl acetate or polyethylene can be used. The amount of sizing agent used is to prevent the ink from being printed and the fragrance component from diffusing and to smoothly print the fiber layer 12, and the perfume component can be applied, relative to the fiber layer before the application of the sizing agent. The weight of 12 is preferably from 0.01 to 3% by weight, particularly preferably from 0.05 to 1% by weight.

The release sheet 40 shown in Fig. 2(b) is subjected to a release treatment after laminating the film 11 and the fiber layer 12. In order to display the product name of the individual package 30 or to increase the product value of the individual package 30, a print 13 containing characters, figures, symbols, and patterns is applied to one or a portion of the fiber layer 12. In the release sheet 40, the printing surface is the outer surface in a state where the sanitary pad 20 is packaged.

The release sheet 40 shown in Fig. 2(c) has a multilayer structure. The release sheet 40 has an outer layer 14 made of a synthetic resin, and an inner layer 15 made of a synthetic resin different from the synthetic resin of the outer layer 14. A peeling layer 16 is formed on the inner surface of the inner layer 15. Further, the synthetic resin which is the outer layer 14 which is the outer surface of the release sheet 40 is blended with a fragrance component. The inner layer 15 functions as a barrier layer for preventing the fragrance component blended in the synthetic resin of the outer layer 14 from oozing out to the inner side of the release sheet 40. The release layer 16 functions to peel the adhesive applied to the outer surface of the inner sheet of the panty liner 20 from the release sheet 40. According to the release sheet 40 shown in Fig. 2(c), the fragrance component blended in the synthetic resin of the outer layer 14 can be used to release the fragrance to the outside. Further, since the inner layer 15 functions as a barrier layer of the fragrance component, the fragrance does not transfer to the sanitary pad 20.

In the release sheet 40 shown in Figs. 2(a) to (c), the fragrance component can be enclosed in the microcapsules, and when the individual package 30 is hand-held, or when the individual package 30 is opened, the aroma is started. . As a result, the fragrance can be effectively imparted with a minimum amount of the fragrance component required. For example, in the release sheet 40 shown in Fig. 2(a), as shown in the enlarged view of the fibrous layer 12 of the drawing, that is, as shown in Fig. 3, the fibrous layer 12 carries the microcapsules 17 in which the fragrance component is enclosed. When the individual packages 30 are taken out of the package, or when the individual packages 30 are opened, an external force is applied to the microcapsules 17 by the force of the hand holding the individual packages 30 or the friction with the package. It ruptured. As a result, the flavor component enclosed in the microcapsule 17 starts to be released to the outside. Figures 2(b) and (c) are also the same. In Fig. 2(b), the microcapsules in which the fragrance component is encapsulated may be added to the printing ink. In Fig. 2(c), the microcapsules in which the fragrance component is encapsulated may be incorporated into the synthetic resin.

As the release sheet, paper, a nonwoven fabric, a woven fabric, a knitted fabric, a film, or a laminate thereof can be used as the base sheet, and a known release treatment can be carried out.

As the material of the packaging sheet, paper, non-woven fabric, woven fabric, knitted fabric, film, or the like can be used.

The fragrance usually contains an oil component. Therefore, in the individual package 30 shown in Fig. 1, when the fragrance is applied to the entire area of the release sheet 40, the adhesive for integration with the packaging sheet (hot melt) is formed due to the oil component contained in the fragrance. Adhesive properties such as an adhesive or the like, or the like, may affect the packaging sheet and the release sheet, or the adhesive may be exposed on the surface of the packaging sheet, and the individual packages may be bonded to each other. Therefore, in order to securely fix the packaging sheet and the release sheet, it is preferred not to impart a fragrance to the fixing portion.

As a form in which the fragrance is not applied to the fixing portion 41 as described above, it is preferable to impart a flavor to a portion other than the position of the fixing portion, and specifically, to impart a flavor in a linear form.

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 positions spaced apart in the longitudinal direction of the sanitary pad 20, and the release sheet 40 is not The portions 42 and 42 where the packaging sheets 10 are joined are given a fragrance.

Further, in the case where paper is used as the release sheet of the fiber layer 12, the effect of preventing the oil component from diffusing in the sheet by the above sizing agent can be obtained. Thereby, it is possible to avoid the problem that the adhesiveness of the adhesive such as the hot-melt adhesive is lowered due to the oil component. When a release sheet which is not subjected to sizing treatment or the like is used, embossing can be performed. As a result, the embossed portion becomes a barrier portion that hinders the movement of the oil component, and the oil component hardly reaches the sealing portion 31.

As a method of imparting a fragrance to the release sheet 40 as shown in FIG. 4, for example, a method of using the coating apparatus shown in FIG. 5 can be mentioned. The coating device 10 shown in Fig. 5 is provided with a pair of smoothing rolls 11, 12 arranged in the vertical direction in contact with each other. Between the rolls 11, 12, the original material 40a of the release sheet 40 is inserted. The original material 40a is transported from right to left in FIG. The drums 11 and 12 are made of, for example, metal or rubber. The raw materials of the drums 11, 12 may be the same or different. Further, the diameters of the rollers 11, 12 may be the same or may be different. The rollers 11, 12, in Fig. 5, are rotatable in the directions indicated by the arrows, i.e., in mutually opposite directions. A plurality of fragrance ejecting portions 13 are disposed above the upper drum 11 of the two rollers 11 and 12. The discharge portions 13 are arranged at equal intervals along the axis of the drum 11. Further, the discharge portion 13 is located on the central axis of the drum 11. The discharge unit 13 is connected to a fragrance storage tank (not shown) via a pump (not shown). The discharge portion 13 has a structure in which a small amount of fragrance can be continuously discharged. In order to achieve this, the ejection portion 13 is in the shape of a syringe. The discharge port 13a of the discharge portion 13 contacts or approaches the surface of the drum 11. The slitter 14 is disposed at a position downstream of the rollers 11 and 12 in the conveyance direction of the original material 40a of the release sheet 40. The slitter 14 is composed of a circular cutter. The original material 40a is cut at a specific interval by the slitter 14 in the width direction thereof.

The method of applying the fragrance using the coating device shown in Fig. 5 is as follows. The fragrance sprayed from the discharge port 13a of the discharge portion 13 adheres to the circumferential surface of the drum 11 among the rollers 11, 12 which rotate in opposite directions in the contact state. The drum 11, which is rotated in the direction indicated by the arrow in Fig. 5, is such that the trajectory 15 drawn by the perfume adhering to the circumferential surface of the drum 11 is linear along the circumferential direction of the drum 11. The trajectory 15 is formed in plural in the axial direction of the drum 11. As a result, on the circumferential surface of the drum 11, the fragrance adheres in a line shape in the circumferential direction thereof.

The fragrance adhered in a line shape is transferred to the original material 40a of the release sheet 40 passing between the rolls 11, 12. As a result, the fragrance is applied in a plurality of lines on the original material 40a in the direction in which it is conveyed. The width of the applied perfume may be about 1 mm in the finest case. Thereafter, the original material 40a passes between the rolls 11, 12, and is cut at a specific interval in the width direction by the slitter 14. As a result, the original material 40a becomes a narrow elongated strip 40b. The rectangular strip 40 is obtained by further cutting at a predetermined interval in the width direction of the elongated strip 40b.

According to the above method, even if the amount of the fragrance sprayed from the discharge portion 13 is unavoidably changed, the amount of the fragrance adhered to the circumferential surface of the drum 11 can be uniformized during the rotation of the drum 11. . Therefore, the fragrance can be transferred to the original material 40a of the release sheet 40 in a uniform amount. For example, even if the amount of the fragrance ejected from the ejecting portion 13 is generated by the pulsation of a pump (not shown) for ejecting the fragrance, the amount of fragrance emanating from the ejecting portion 13 is changed over time as shown in Fig. 6(a), but the drum 11 is rotated. During this process, the amount of the fragrance adhering to the circumferential surface of the drum 11 is uniformized, and when transferred to the original material 40a, it is also in the homogenized state shown in Fig. 6(b). Therefore, the applied portion has a uniform coating width in the longitudinal direction thereof. As can be seen from the above description, the method can be particularly effective for the case where a small amount of perfume is applied in a narrow width or in the case of a fine pitch. Further, the method can be further improved by using the above sizing agent in combination.

Further, in the coating device 10 shown in Fig. 5, the pair of rollers 11, 12 are arranged in the vertical direction, but instead, the rollers 11 and 12 may be arranged side by side in the horizontal direction. Further, in the coating device 10, a plurality of discharge portions 13 are disposed. Alternatively, a single discharge portion disposed in a plurality of discharge ports may be used to discharge the fragrance.

The present invention has been described above based on the preferred embodiments of the present invention. However, the present invention is not limited to the above embodiments, and various modifications can be made. For example, when the packaging sheet 10 and the release sheet 40 are not integrated and the fragrance is applied to the release sheet 40, it may be applied to the entire surface of the non-peeling surface of the release sheet 40. Further, it is also possible to use only the release sheet and the absorbent article to which the fragrance is imparted, or the packaging form in which the absorbent article for imparting a fragrance to the release sheet is packaged in a plurality of sheets without using the packaging sheet.

Further, in each of the above-described embodiments, the case where the outer surface of the peeling sheet 40 is packaged in a state in which the outer surface is provided with a fragrance is explained, and in the individual package 30, the fragrance component is not excessively transferred to the sanitary state. In the case of the pad 20, the inner surface of the release sheet 40, that is, the surface facing the sanitary pad 20 may be imparted with a fragrance.

Further, in the above embodiment, the release sheet 40 is present on the inner surface of the packaging sheet 10, and the sanitary pad 20 can be used as the absorbent article for individual packaging on the inner side. However, the present invention can also be applied to other absorbents. Items such as sanitary napkins or incontinence pads.

[Industrial availability]

The absorbent article after use is usually discarded after the article is wrapped in a release sheet or a package sheet, or thrown into a container that can be sealed together. Therefore, by applying a fragrance to the release sheet according to the present invention, the release sheet can be used. Covers the odor generated in the absorbent article after use. Further, when the packaging sheet is formed of a permeable material, the aroma is released before the individual packages are opened, so that the wearer can be given a feeling of relaxation before using the absorbent article. Further, since the release sheet is imparted with a fragrance without imparting a fragrance to the absorbent article itself, when the article contains a superabsorbent polymer or a deodorant, the performance deterioration can be prevented. Further, since the self-absorbent article itself emits only the weaker aroma, it is not easy to be found by others to wear the article.
