The present invention relates to a disposable absorbent article for women characterized in that to apply a menthol component to give a cool and refreshing feeling to the skin to reduce the discomfort caused by physiological action during menstrual periods to improve the fit.

In general, the disposable absorbent article for women absorbs and removes excrement due to physiological action, and refers to a disposable absorbent article for women (physiological) such as a sanitary napkin and a panty liner.

The performance of the disposable absorbent article is primarily due to the physiological action of the possible aspects to focus on the absorption rate, the amount of absorption of the excretion and no burden on wearing, the excretion does not leak out, and even if worn for a long time red spots or skin It is divided into usability aspects without rashes such as inflammation, and all require excellent performance.

Since women's physiological products are in close contact with the skin, the humidity of the product surface hydrates the skin, and skin sores are generated by friction between the product surface and the skin. The dysmenorrhea that occurs during menstruation, ie, pain in the stomach, pain in the head, feeling depressed, or feeling unsatisfied somewhere uncomfortable, is different depending on the individual, but psychologically unstable and accompanied by an unpleasant feeling.

The technical development of the conventional women's physiological absorbent articles is the basic performance of absorbent articles, namely absorption rate, absorption, improvement of side glands due to the introduction of blocking cuffs, improvement of wearing comfort due to thickness reduction, physiology by deodorization, deodorization of physiological odor generated during menstruation Although it has been developed for suppressing odor and antibacterial activity, there has been no attempt to improve the fit by cooling the skin during the menstrual period to be attempted by the present invention and giving a refreshing feeling to reduce discomfort caused by menstrual cramps. An object of the present invention is to provide a disposable absorbent article for women containing the ingredient.

The disposable absorbent article for women consists of a single or a combination of pulp, absorbent paper, etc. pulverized with an absorbent, and at the same time, contains a water-insoluble superabsorbent polymer, if necessary, to cover both end portions in the width direction from the lower surface thereof. Or a non-woven fabric comprising a liquid-impermeable sheet and an absorbent body composed of a laminate sheet of a film and a non-woven fabric, etc., covering the liquid-impermeable sheet and heat-sealed at both ends in the longitudinal direction, or a perforated film or a perforated film and a nonwoven fabric Auxiliary components such as a main component of the bonded liquid permeable sheet and a fixing adhesive layer for fixing the absorbent article (women's disposable absorbent article) to the wearer's underwear, and a blocking portion for preventing lateral leakage of physiological excretion.

The menthol (mint brain) component to be applied to the present invention is obtained by distilling peppermint oil obtained by distilling peppermint, or obtained by solids. The powder is dissolved in a powder or in a solvent and sprayed on the surface of an absorbent body or a liquid permeable sheet, and is liquid permeable. The sheet is impregnated with a solution in which the menthol component is dissolved to apply the menthol component to the absorbent article. In addition, peppermint oil or peppermint water containing menthol may be applied to the absorbent article by spraying or impregnating the same as the above method. In this way, by extracting the active ingredient from the herbal ingredients or natural plants to be in a solid or solution state can be applied to absorbent articles.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 shows a plan view of the case where the absorbent article S has the semi-elliptic flap 5, and the components are the two-liquid permeable sheet 1, the liquid impermeable sheet 2, the absorbent body 3, and the side leakage prevention block. It consists of a part 4, a semi-elliptic side flap 5, a fixing adhesive layer 6 to be attached and held on the underwear, and an adhesive layer protector 7 which prevents contamination of the fixing adhesive layer 6.

FIG. 2 shows a plan view of a straight line as another embodiment of the absorbent article S. Unlike FIG. 1, the liquid permeable sheet 1 covers the absorber and the liquid impermeable sheet 2, and is composed of a separate material. The side-prevention blocking part 4 and the semi-elliptic side flap 5 do not exist.

1 and 2, the liquid impermeable sheet 1 may be composed of a perforated film, a nonwoven fabric, or a combination thereof, and the liquid impermeable sheet 2 is a breathable or non-breathable film and a nonwoven fabric laminated to these films. It is made of material such as waterproof. The absorbent body 3 is composed of pulverized pulp, blotter paper, nonwoven fabric and combinations thereof, and contains superabsorbent polymers as necessary, and the amount of superabsorbent polymer and pulverized pulp is adjusted according to the amount of physiological excretion and also in thickness. It can be formed into a thin absorbent sheet.

Side leakage prevention blocking portion (4) is a material that is separate from the liquid permeable sheet (1) material of the absorbing article (S) lengthwise both ends and the lateral both ends. It is designed to attach the liquid permeable sheet (1) and the liquid impermeable sheet (2) together with a hot melt or hot melt adhesive, and to improve the side leakage prevention effect by arranging an elastic chamber at the side edges of the side of the blocking portion (4). Can be.

The semi-elliptical side flap 5 includes an adhesive layer 6 for fixing the flap 5 to the liquid impermeable sheet 2, and makes the absorbent article S easy to fix to the crotch portion of the women's underwear. The heat-sealed adhesive portion 8 is formed on the semi-elliptic side flap 5 to not only easily fold the semi-elliptic side flap 5 but also to prevent the physiological excretion from passing through the absorber 3 in both directions. do. The heat-sealed adhesive portion 8 simultaneously extends the material of the liquid-permeable sheet 1, the liquid-impermeable sheet 2, and, if necessary, the side leakage preventing blocking portion 4 at both ends of the longitudinal direction of the absorbent article S. Therefore, the side flap 5 is formed by thermal welding in the longitudinal direction of the absorbent article (S). The shape of the side flap 5 can be formed symmetrically and asymmetrically with shapes other than semi-elliptic.

The fixing adhesive layer 6 of the absorbent article S is to fix the absorbent article S to the wearer's underwear so that the absorbent article S is kept in close contact with the skin, and the liquid impermeability toward the liquid impermeable sheet 2 of the absorbent article S is maintained. It is formed in the sheet 1 or the liquid permeable sheet 2 in the longitudinal direction of the absorbent article S, and also in the lower part of the side flap 5. The method of forming the fixing adhesive layer 6 may be variously formed.

A guard 7 is attached to prevent contamination of the fixing adhesive layer 6.

The menthol component that is applied to the present invention can be obtained by cooling the peppermint oil obtained by distilling the peppermint which is a natural plant, and the liquid state and the liquid state of peppermint oil and peppermint. The menthol component thus obtained is dissolved in a fine powder or solvent and applied to the absorbent body 3 or the liquid permeable sheet 1 in a liquid state.

Herein, the absorbent (3) is a constituent except for the liquid-permeable sheet (1) and the liquid-impermeable sheet (2), and includes tissues having an absorption function, non-woven pulverized pulp, thin sheets containing a super absorbent polymer, and the like. The upper layer of the absorber 3 or an intermediate layer thereof is applied by spraying the menthol component in a powder or liquid state. In addition, the liquid permeable sheet 1 may be applied in the same manner as described above, and may be applied by impregnation in a liquid solution containing a menthol component.

The content of the menthol component is applied to 0.01 to 1.0 grams per absorbent article (S), preferably 0.01 to 0.5 grams, more preferably 0.01 to 0.2 grams.
