The sanitary napkin 1 having such a structure is worn by the userBThe sanitary napkin 1 is attached to the inner surface of the clothing (e.g., underwear) of the user via the clothing-fixing adhesive section 7 and the pair of front-direction adhesive sections 72 and 72, and then the pair of wing sections 6 and 6 are folded back toward the outer surface of the clothing and attached to the outer surface of the clothing via the pair of wing-fixing adhesive sections 71 and 71, thereby fixing the sanitary napkin to the clothing of the wearer.
In addition, since the present invention does not necessarily require the pair of wing portions, the present invention does not need to include such wing portions depending on the form of the absorbent article.
Hereinafter, various components of the absorbent article that can be used in the individually packaged body of the present invention will be described in further detail with reference to the sanitary napkin 1.
[ absorbing layer ]
In the sanitary napkin 1, as shown in fig. 2, the absorbent layer 21 is provided in the front direction D of the sanitary napkin 1 in plan viewFIn the width direction DWIn the longitudinal direction D of the wide portion 20 having a larger dimension than the surrounding areaLAnd the width direction DWA wide range of predetermined profile shapes. As shown in FIG. 4, the absorbent layer 21 is formed in the thickness direction D of the sanitary napkin 1TThe front sheet 2 and the back sheet 3 are arranged therebetween, and are formed of a sheet-like member containing a fragrance as a volatile component.
The sheet-like member forming the absorbent layer 21 is composed of a base material capable of holding a perfume as a volatile component. In the present invention, the wide width portion is not limited to the case where the absorbing layer containing the fragrance is disposed, and the absorbing layer not containing the fragrance may be disposed between the front sheet and the back sheet.
In the present embodiment, the base material capable of holding the fragrance is not particularly limited as long as it can hold the liquid fragrance in the production process, and examples thereof include a fabric (e.g., a nonwoven fabric, a woven fabric, a knitted fabric, etc.), a porous resin sheet (e.g., a sponge sheet, etc.), and the like. The substrate may be used alone as a substrate for the absorbent layer, or may be used in combination with other constituent members (for example, a front sheet, a back sheet, an intermediate sheet, a core wrap sheet, and the like). In addition, the weight per unit area of the absorbent layer 21 is smaller than the weight per unit area of the absorbent body 4 described later, and thus, in the developed state, the sanitary napkin 1 is oriented in the front direction DFSide weight per unit area ratio in the rear direction DBThe weight per unit area of the side is small. Thus, when the individual package 10 is held with the palm of one hand, the front direction D in which the flavor-containing region described later is arranged is setFThe side is easily oriented in the width direction DWA pressed sanitary napkin 1The perfume (2) is easily released to the outside of the individual package 10, and the user can easily perceive the presence of the perfume before the individual package 10 is opened.
(volatile component-containing region)
The sanitary napkin 1 has a 1 st fold line LL in the width direction1Front direction DFThe side end portion includes a perfume-containing region containing a perfume as a volatile component, and more specifically, the absorbent layer 21 contains a perfume. By using a perfume as a volatile component, the presence of the perfume can be sensed by olfaction when the individual package 10 is held with the palm of one hand.
Here, in the individually packaged state, the flavor-containing region is arranged at least in the thickness direction D of the individually packaged body 10TOn the 1 st surface S1The gas communication portion 13 is also disposed on the 1 st surface S at the side position as described above1And (3) side. Therefore, the perfume is easily released to the periphery of the individual package 10 through the gas communication portion 13, and the user easily senses the presence of the perfume before the individual package 10 is opened. In addition, the perfume-containing region is also folded along the 1 st fold line LL in the width direction1And a region for forming an additional volatile component-containing region. The sanitary napkin 1 has an additional volatile component-containing region, and the persistence of the perfume contained in the sanitary napkin 1 is further improved. However, in the present invention, the sanitary napkin 1 may not have an additional volatile component-containing region, and an additional perfume-containing region that is not continuous with the perfume-containing region may constitute the additional volatile component-containing region. The fragrance used in the present invention is preferably a liquid fragrance used in the production of an absorbent article, but is not limited to a liquid fragrance used in the production of an absorbent article, and may be a solution-like, solid-like or semi-solid-like fragrance, for example.
In the present embodiment, the sanitary napkin 1 contains a temperature sensitive agent as an additional functional agent to be described later in addition to the perfume, and the perfume imparts an odor corresponding to the function of the temperature sensitive agent. Thus, the user can estimate the function of the temperature sensitive agent as the additional functional agent by sensing the presence of the flavor before opening the individual package 10. Examples of the perfume for imparting an odor corresponding to the function of the temperature-sensitive agent include perfumes for imparting a plant odor that generates a temperature-sensitive effect by contacting the skin or mucous membrane, and examples thereof include linalool, geraniol, geranial, neral, borneol, isoborneol, 1, 8-cineole, 4-terpineol, geranyl acetate, 2-pinen-5-ol, trans-2-octenal, trans-2-decenal, trans-2-dodecenal, and the like that impart a ginger-like odor. Examples of the perfume that imparts an odor corresponding to the function of the temperature-sensitive agent include perfumes that impart a plant odor with which temperature is perceived, and examples thereof include d-limonene, (6S) -methyloctanal, (8S) -methyldecanal, trans-4, 5-epoxy-2-decenal, (6Z,8E) -undecane-6, 8, 10-trien-3-one, and the like that impart a grapefruit-like odor; hinoki oil, hinokitiol, phytoncide, alpha-pinene, etc., which impart a cypress-like fragrance. As other flavors, flavors having a lotus-like flavor can be cited. As described later, the functional agent to be added in the present invention is not limited to the temperature sensitive agent. For example, when the additional functional agent is a cooling agent, the fragrance that imparts an odor corresponding to the function of the cooling agent may be a fragrance that imparts an odor of a plant that produces a cooling sensation when the fragrance comes into contact with the skin or mucous membrane, and examples thereof include menthone, menthyl acetate, and the like that impart a mint-like fragrance. When the additional functional agent is an antibacterial agent, the perfume giving an odor corresponding to the function of the antibacterial agent may be a perfume giving an odor of a plant having a widely known antibacterial function, and examples thereof include leaf alcohol, linalool, geraniol, and the like giving a fragrance like a tea (tea) leaf.
In the present invention, the outer shape, various dimensions, unit area weight, and the like of the absorbent layer can be any outer shape, various dimensions, unit area weight, and the like corresponding to the type, arrangement, and the like of the functional agent. The property of the functional agent is not particularly limited, and for example, the functional agent may be a solution-like functional agent containing an active ingredient, may be a solid-like component that can be applied, may be composed of a liquid-like active ingredient, or may be a volatile component.
The liquid-permeable sheet-like member is not particularly limited as long as it has various properties (for example, liquid permeability, skin touch, flexibility, strength, and the like) that can be used as a top sheet of an absorbent article, and various nonwoven fabrics such as a hot air nonwoven fabric, a spunlace nonwoven fabric, a spunbond nonwoven fabric, and a point-bond nonwoven fabric, and a porous resin film, for example, can be used. The sheet-like member is not particularly limited in structure, and various sheet-like structures such as a flat sheet-like structure having a plurality of openings and a concavo-convex structure can be used in addition to a flat non-porous sheet-like structure.
When a nonwoven fabric is used as the surface sheet, the type of the constituent fibers is not particularly limited, and examples thereof include hydrophilic fibers such as cellulose-based fibers and hydrophilic thermoplastic resin fibers (e.g., hydrophilic olefin-based resins, hydrophilic polyester-based resins, etc.) subjected to a hydrophilization treatment. These fibers may be used alone, or 2 or more kinds of fibers may be used in combination.
(functional agent)
The sanitary napkin 1 contains a functional agent in addition to the perfume. Examples of the functional agent include a temperature sensitive agent. In the present embodiment, the functional agent is applied to the non-skin-facing surface S of the top sheet 2BAnd (3) side. The temperature sensitive agent used as the functional agent includes: a temperature-sensitive component which does not generate heat by itself but stimulates a temperature-sensitive receptor of the skin of the wearer to make the wearer feel temperature; and a solvent component which dissolves the temperature sensitive component.
In the sanitary napkin 1, the temperature sensitive agent is contained in the non-skin-facing surface S of the topsheet 2 of the wide portion 20 in plan viewBThe side portion is substantially the entire, but may be included in a local portion (for example, only the central portion) as long as the predetermined temperature sensing function can be exhibited.
In order to prevent volatilization or migration to other areas before the sanitary napkin 1 is used, the functional agent may also be protected in a water-disintegrable protective member such as microcapsules. The functional agent encapsulated in the microcapsule disintegrates when contacted with a liquid (exemplified by menstrual blood, urine, and sweat), and releases the functional agent to the outside. The discharged functional agent is vaporized by the body temperature of the wearer or the like, or comes into contact with the skin of the wearer, thereby exerting a predetermined function on the wearer.
Examples of the raw material of the microcapsule include: a saccharide; examples of the polysaccharide include monosaccharides (e.g., glucose), disaccharides (e.g., sucrose), and polysaccharides (e.g., dextrin, glucomannan, sodium alginate, and water-soluble starch); gelatin; and water-soluble polymers (for example, polyvinyl alcohol and polyvinyl acetate).
The microcapsules are commercially available, and examples thereof include INCAP (trademark) commercially available from Symrise (Dekkaiber). In addition, the microcapsules can be produced, for example, as follows: the raw material of the microcapsule is dissolved in water to form an aqueous solution, and the functional agent and the surfactant are mixed in the aqueous solution, and the mixture is dried under reduced pressure while spraying the aqueous solution.
Further, since the fragrance is contained in the absorbent layer 21 disposed in the wide portion 20 as described above, by containing the functional agent in the topsheet 2, the position containing the fragrance and the position containing the functional agent are in the thickness direction D in the developed state of the sanitary napkin 1TThe above is different. Therefore, the fragrance and the functional agent hardly interfere with each other, and the fragrance and the functional agent can sufficiently exert their respective functions. However, the present invention is not limited to the position containing the perfume and the position containing the functional agent in the thickness direction DTIn the above-described different form, the volatile component-containing region and the region containing the additional functional agent may be different in the planar direction or may be in the thickness direction D in the developed stateTThe thickness direction D may be different from the planar directionTAnd/or overlap in the planar direction.
In the sanitary napkin 1, the temperature sensitive agent is applied to the non-skin-facing surface S of the topsheet 2BOn the other hand, the temperature sensitive agent can be applied to the skin-facing surface S of the topsheet 2 even when the sanitary napkin 1 is wornFThe side permeates and contacts with the skin of the lower abdomen of the wearer, so the temperature sensing component of the temperature sensing agent can stimulate the heat sensing receiver of the skin,the wearer's lower abdomen is given a feeling of warmth.
By thus warming the lower abdomen of the wearer, that is, the portion close to the uterus of the wearer, it is expected to alleviate dysmenorrhea of the wearer, or alleviate symptoms such as premenstrual syndrome, cold intolerance, climacteric disorder, and the like.
In addition, in the present invention, the additional functional agent is disposed in the thickness direction DTThe position of (a) is not particularly limited as long as the temperature sensitive agent can contact the skin of the wearer when the absorbent article is worn.
The temperature-sensitive component contained in the temperature-sensitive agent is preferably a plant-derived compound from the viewpoint of making the user feel comfortable, and examples thereof include capsaicin, vanillyl alcohol alkyl ether derivatives (e.g., vanillyl ether, vanillyl alcohol butyl ether, vanillyl alcohol pentyl ether, vanillyl alcohol hexyl ether, etc.), ginger extract, ginger oil, and the like. Among these compounds, vanillyl alcohol alkyl ether derivatives, ginger extract, ginger oil and the like are preferably used from the viewpoint of skin irritation. These compounds may be used alone, or 2 or more of them may be used in combination.
When the temperature sensitive agent is applied to a substrate by coating or the like, a solvent component capable of dissolving or dispersing the temperature sensitive component may be used together with the temperature sensitive component, and examples of such a solvent component include a lipophilic solvent and a hydrophilic solvent.
Examples of the lipophilic solvent include oils and fats such as natural oils (e.g., fatty acid esters such as triglycerides, coconut oil, linseed oil, and the like), hydrocarbons (e.g., paraffin, and the like). On the other hand, examples of the hydrophilic solvent include water and alcohols, and examples of the alcohols include lower alcohols (e.g., methanol, ethanol, ethylene glycol, and glycerol), and higher alcohols (e.g., octanol and lauryl alcohol).
Among these solvents, lipophilic solvents such as fats and oils or alcohols are preferably used in terms of ease of control of volatility, and lipophilic solvents such as fats and oils are more preferably used in terms of ease of maintenance of absorption performance of the absorbent article.
After the application of such a solvent to the substrate, the solvent may remain in the application target site in a state of being cured or semi-cured, or the solvent may be volatilized and only the solute may remain.
In addition, from the viewpoint of the temperature-sensitive effect, the concentration of the temperature-sensitive component in the temperature-sensitive agent when the temperature-sensitive agent contains the solvent is preferably 0.0001% by mass or more and 5.0% by mass or less, more preferably 0.0005% by mass or more and 3.0% by mass or less, and further preferably 0.1% by mass or more and 1.0% by mass or less.
In the present invention, the functional agent is not limited to the temperature sensitive agent, and any functional agent can be used according to the desired action. Examples of such functional agents include a cold feeling agent, a heat generating agent, and a drug (e.g., a skin astringent, an anti-inflammatory agent, an antibacterial agent, a pH adjuster, and a humectant). These functional agents may be used in combination, for example, such that 1 kind of functional agent (e.g., a temperature sensitive agent) is disposed in a part of the absorption layer and another kind of functional agent (e.g., a cooling agent) is disposed in another part in a plan view.
In the present invention, the cooling agent usable as the functional agent includes a cooling component which does not absorb heat and stimulates the cooling sensation receptor of the skin of the wearer to make the wearer feel a cooling sensation, and may include a solvent component which dissolves or disperses the cooling component as necessary. Examples of the cooling component include menthol (e.g., l-menthol); menthol derivatives (e.g., menthyl lactate, menthyl glycerol ether, etc.); methyl salicylate; essential oils derived from plants such as peppermint and eucalyptus. The solvent component that may be contained in the cooling agent may be the same as the solvent component that may be contained in the temperature-sensitive agent.
In addition, in the case where the cooling agent contains a solvent, the concentration of the cooling component in the cooling agent is preferably 0.0001% by mass or more and 5.0% by mass or less, more preferably 0.0005% by mass or more and 3.0% by mass or less, and further preferably 0.1% by mass or more and 1.0% by mass or less, from the viewpoint of the cooling effect.
The heat generating agent usable as the functional agent of the present invention has an action of warming the skin of the wearer by its own heat generation, and examples thereof include heat generating agents utilizing chemical properties such as the heat of oxidation of metal powder such as iron powder, the heat of neutralization of acid or alkali, and the heat of hydration of inorganic salts. The heat generating agent may be used by being dissolved or dispersed in a solvent component or a dispersion medium.
In the present invention, the drug that can be used as the functional agent imparts a predetermined pharmacological action to the skin of the wearer, and examples thereof include a skin astringent, an anti-inflammatory agent, an antibacterial agent, a pH adjuster, and a moisturizing agent.
Examples of the skin astringent include skin astringent containing astringent components such as zinc oxide, aluminum sulfate, tannic acid, and oil-soluble polyphenols (e.g., phellodendron extract, Hypericum erectum extract, Chamomilla extract, birch extract, loquat leaf extract, linden extract, and hop extract).
Examples of the anti-inflammatory agent include anti-inflammatory agents containing anti-inflammatory components derived from natural sources (e.g., peony extract, hypericum erectum extract, chamomile extract, mugwort extract, perilla extract, etc.), synthetic anti-inflammatory components (e.g., allantoin, dipotassium glycyrrhizinate, etc.), and the like.
Examples of the antibacterial agent include antibacterial agents containing antibacterial components derived from natural sources (e.g., phellodendron extract, olive leaf extract, chamomile extract, Sasa albo-marginata extract, zanthoxylum extract, perilla extract, houttuynia cordata extract, hops extract, eucalyptus extract, mugwort extract, etc.), synthetic antibacterial components (e.g., ethylhexylglycerin, etc.), and the like.
Examples of the pH adjuster include pH adjusters containing weakly acidic components for keeping skin weakly acidic, such as malic acid, succinic acid, citric acid, tartaric acid, and lactic acid.
Examples of the moisturizer include moisturizers containing a moisturizing component such as a polyhydric alcohol (e.g., glycerin, propylene glycol, butylene glycol, sorbitol), urea, and an emollient component (e.g., petrolatum).

In addition, the sanitary napkin 1 has the wide width portion 20, so that the sanitary napkin 1 has the longitudinal direction DLIs relative to the longitudinal direction D of the absorbent body 4LIs relatively large. Thus, the maximum dimension in the longitudinal direction of the absorbent body 4 is relatively small with respect to the maximum dimension in the longitudinal direction of the back sheet 3, and the longitudinal direction D of the back sheet 3LWith respect to the longitudinal direction D of the absorbent body 4LRatio of the maximum size of (a) to the width direction D of the back sheet 3WWith respect to the width direction D of the absorbent body 4WThe ratio of the maximum size of (a) is relatively large. That is, the back sheet 3 of the sanitary napkin 1 is arranged in the longitudinal direction DLExtended longer in the longitudinal direction D of the sanitary napkin 1LIs large in size. However, the absorbent article of the present invention is not limited to the longitudinal direction D of the back sheetLRelative to the longitudinal direction D of the absorbent bodyLRatio of the maximum dimension of (a) to the width direction D of the back sheetWWith respect to the width direction D of the absorbent bodyWThe longitudinal direction D of the back sheetLRelative to the longitudinal direction D of the absorbent bodyLRatio of the maximum dimension of (a) to the width direction D of the back sheetWWith respect to the width direction D of the absorbent bodyWMay be equal or smaller than the ratio of the maximum size of (c).
