In the absorbent article disclosed in Patent Document 1, when the cyclodextrin and the flavor component are contained in the same layer, when the body fluid such as urine discharged from the wearer reaches the layer, the moisture contained in the precursor fluid is The complex compound with the former cyclodextrin acts so that the flavor component is released before the cyclodextrin complex is present. Therefore, the ammonia component of the flavor component and the odor of the body fluid is present in the pre-recorded layer. However, if the flavor component and the ammonia component are simultaneously present in the same layer, the former flavor component is bound by the cyclodextrin, which hinders the adsorption of the cyclodextrin to the ammonia component, and thus may not be sufficiently inhibited from wearing. The odor of the body fluid emitted by the person.

Accordingly, an object of the present invention is to provide an absorbent article which can sufficiently suppress an odor emitted from a body fluid of a wearer.

The absorbent article of the present invention comprises: a liquid-permeable layer, a liquid-impermeable layer, an absorbent layer between the two layers, and a cyclodextrin-containing layer, wherein the absorbent article contains: the first fragrance, which is preceded by The cyclodextrin contains the cyclodextrin contained in the layer; and the second fragrance is present in the precursor absorption layer.

In the absorbent article of the present invention, since the first fragrance and the second fragrance are present in different layers, the body fluid such as urine discharged from the wearer reaches the pre-cyclodextrin-containing layer, and the cyclodextrin-containing layer is preliminarily The first fragrance held by the cyclodextrin contained in the medium has been released, and the first fragrance has been released. The cyclodextrin in the unbindered state of the material is difficult to contact with the second fragrance described above, and the ammonia component contained in the precursor liquid can be efficiently adsorbed. As a result, the absorbent article of the present invention cooperates with the aromatic action of the first fragrance and the second fragrance and the adsorption of the ammonia component by the unbound cyclodextrin, and can effectively suppress the pre-recording An unpleasant odor from body fluids. Further, in the absorbent article of the present invention, the "cyclodextrin-containing layer" means a layer containing at least a cyclodextrin in which the first fragrance is held, and may contain an un-caged cyclodextrin or A cyclodextrin or the like which is an active ingredient other than the first fragrance.

According to the present invention, it is possible to provide an absorbent article which can sufficiently suppress the odor emitted from the body fluid such as urine discharged from the wearer.

The length in the width direction. In addition, "the field other than the field of the body fluid absorption" refers to a field other than the field of the pre-recorded body fluid absorption in the direction of the outer side in the long-axis direction and the width direction from the field of absorption of the body fluid, and the field includes: The field of body fluid discharged from the wearer and the field of the body fluid discharge position not corresponding to the wearer are absorbed, but the field of body fluid discharged from the wearer can be absorbed.

The light incontinence pad 1 according to the first embodiment of the present invention is composed of a liquid-permeable non-woven fabric or a liquid-permeable non-woven fabric on the opposite side of the wearer's skin in the thickness direction D _T as shown in FIG. 2 . Any of the liquid-permeable sheets such as a plastic film, the surface sheet 2 as a liquid-permeable layer; and the non-liquid-permeable non-woven fabric or plastic film on the non-skin facing side of the wearer. The back sheet 3 is formed as a non-liquid-permeable layer; and the absorbent material 6 containing at least the absorbent polymer is disposed between the front surface sheet 2 and the front back sheet 3, and the liquid-permeable sheet 7 is used. to be clamped, 7 '(e.g., airlaid nonwoven, etc.) as the absorbent layer of the absorbent sheet S _a; and the absorbent sheet S _a located before and referred back sheet between 3 and containing a synthetic or natural flavors maintained The cyclodextrin of a mixture of a fragrance (first fragrance) such as a fragrance and a mixture of an absorbent polymer and a liquid-retaining substance (for example, pulp) contains the absorbent layer 4 to be composed of two liquid-permeable sheets (for example). a cyclodextrin containing a carrier sheet 5, 5' formed by a thin paper or the like) And the layered material from the front surface sheet to the front surface sheet is folded so as to be sandwiched from the outer sides in the width direction of the front surface, and is bonded to the front layer layer, and the inner side in the width direction is preceded by The side edge of the side is a free end, a pair of side flaps 8, 8' extending in the direction of the long axis in the front direction, and a vicinity of the fold of the pair of side flaps 8, 8', and Each of the pair of side flap sheets is provided with two members of the linear elastic members 9, 9'.

In the present embodiment, the absorbent sheet S _A (absorbent layer) is not particularly limited as long as it has a function of absorbing and retaining body fluid such as urine discharged from the wearer. As described above, the absorbent material 6 containing at least the absorbent polymer is sandwiched between two liquid-permeable sheets such as air-laid nonwoven fabric. Here, the "absorbent polymer" is a polymer that can absorb and retain water, and examples thereof include a polymer having a three-dimensional network structure in which a water-soluble polymer is moderately bridged. Specifically, a starch-based, acrylic-based, or amino acid-based particulate or fibrous polymer can be given. Such an absorbent polymer is not only water, but also an odor formed by an ammonia component or the like.

Also, note can be used before the absorbent sheet S _A (absorption layer) of the absorbent material comprising an absorbent polymer-based as long as those can be, not particularly limited, the absorbent polymer should in addition also may contain pulp In order to allow the body fluid such as urine discharged from the wearer to efficiently contact the ring in the absorbing material layer of the cyclodextrin on the non-skin opposing side of the absorbent sheet. Dextrin, a pre-reportable material, is preferably a liquid-retaining substance that does not contain pulp or the like.

And, referred to before can be used for the absorbent sheet S _A (absorption layer) is liquid-permeable sheet, as long as the system is a liquid-permeable sheet can, is not particularly limited, and may be used for example: airlaid nonwoven, spunbond, A hydrophilic non-woven fabric such as a non-woven fabric (for example, SBS non-woven fabric) or a thin paper. From the viewpoint of liquid permeability, it is preferred that the liquid permeable sheet is an air laid nonwoven fabric.

In the light incontinence pad 1 of the present embodiment, the absorbent sheet S _A described above is disposed such that the above-mentioned absorbent polymer (absorbent material 6) is placed on two liquid permeable sheets 7 and 7' coated with an adhesive. Between the two liquid-permeable sheets 7, 7', the central region in the width direction D _W is preceded so that the field in which the absorbent polymer is disposed (the field of absorbent polymer configuration) and the width direction of the front note In the field adjacent to both sides of D _W , there is no such thing as a pre-recorded absorbent polymer. The previously mentioned absorbent polymer is previously sandwiched between two liquid-permeable sheets 7, 7', and the first two sheets are recorded. In the front side of the liquid-permeable sheet 7, 7', in the front-width direction D _W , there is no field of the pre-absorbent polymer (absorptive polymer non-existing field), respectively, along the long axis direction D _L The folding line extending upward is folded forward in the width direction D _W (so-called wrapping), whereby it can be produced. In addition, the two sides of the two liquid-permeable sheets 7, 7' in the width direction of the front side of the absorbent polymer are not folded in the front side in the width direction, and are oriented toward the skin. Fold in either direction on the face side or on the non-skin side. The non-existent field of each of the two absorbent sheets having the liquid-absorbent sheet sandwiched with the precursor absorbent polymer is such that it is difficult to cause the ex-satisfiable polymer to leak out from the absorbent sheet at the same time. The folded portion (folded portion) of the absorbent sheet has a four-layer laminated structure to increase rigidity. Therefore, even when the absorbent article is worn, the width of the absorbent article is caused by the movement of the wearer's foot or the like. An external force is applied to the outer side of the direction D _W , and it is noted that the absorbent sheet is still difficult to deform. As a result, the absorption area of the body fluid such as urine discharged from the wearer can be ensured, and the good absorption performance of the absorbent article can be maintained.

Further, in the absorbent article of the present invention, the absorbent sheet (absorbent layer) is not limited to the above-described aspect, and for example, the pre-absorbent material may be folded and held by a liquid-permeable sheet. The method is to surround the liquid crystal sheet with three or more liquid-permeable sheets, and to hold the central region in the width direction and/or the long axis direction before the liquid-permeable sheet is preceded. Adjacent fields, and in the field where there is no pre-existing absorbent material (absorptive material non-existent field), the width direction is forwarded along the folding line extending in the long axis direction and/or the front width direction. / or the inner side of the long axis direction is folded, and is produced by this.

When the absorbent sheet produced in such a manner absorbs body fluid such as urine discharged from the wearer, the absorbent polymer in the absorbent sheet swells, and the thickness of the absorbent sheet increases. When the body pressure caused by the weight of the wearer or the like is applied to the absorbent article, the swollen absorbent polymer acts like a pressure buffer layer, so that the body fluid absorbed by the previously mentioned absorbent polymer is difficult to reflow. To the surface sheet (liquid-permeable layer), the pre-recorded body fluid is sufficiently contacted, and the cyclodextrin on the non-skin-facing side of the absorbent sheet is filled with the cyclodextrin in the absorbent layer. chance. Further, if the pre-recorded body fluid is left in the pre-absorbent sheet for a long period of time, the pre-recorded body fluid will spread over a wide range in the direction of the surface of the absorbent sheet, so that the precursor fluid can be contacted from a wider range of fields. Foreword of cyclodextrin. As a result, the cyclodextrin containing the first fragrance of the cyclodextrin in the absorbent layer can be more efficiently and effectively exhibited.

Further, light incontinence pad 1 according to the present embodiment, as shown in lines 2 and 3, the front ends remember each fold edge side portion of the absorbent sheet S _A (absorption layer) is referred to the width direction of the front, before being credited The two liquid-permeable sheets 7, 7' are sandwiched between the folding line and the end portion of the two liquid-permeable sheets 7, 7' in the width direction at the inner side in the width direction. Each of the strip-shaped end regions (the fragrance application fields T _F , T' _F ) extending in the direction of the long axis in the front is coated with a liquid fragrance (second fragrance). By applying a liquid fragrance at such a position, the pre-recorded liquid fragrance is not contacted, and the pre-filled absorbent sheet is used to fix the hot-melt adhesive or the pre-absorbent polymer required in the light incontinence pad 1 and thus is not This results in a decrease in the adhesion of the pre-filler or the absorption of the pre-absorbent polymer, which allows the aroma effect of the pre-liquid fragrance to be exerted. Further, the first fragrance which is bound by the cyclodextrin is released by contact with the body fluid to emit a fragrance, but the liquid fragrance (second fragrance) is a fragrance which is emitted regardless of the presence or absence of the body fluid. The wearer can feel the aroma before wearing it. Even in the past by the cyclodextrin in mind the absorbent sheet containing S _A (absorption layer) at a position remote from the cyclodextrin inner layer of the coating liquid fragrance (perfume 2), the liquid should be not difficult to flavor system of clathrated Adsorption of the cyclodextrin (including the cyclodextrin after the first fragrance has been released) allows the aroma effect of the pre-liquid fragrance to be exerted, and does not hinder the pre-adhesive cyclodextrin from being adsorbed in the pre-loading body fluid. Contains ammonia. Further, the liquid fragrance (second fragrance) to be used in the absorbent article of the present invention is not particularly limited, and any liquid fragrance known in the art such as a natural fragrance or a synthetic fragrance can be used, but in consideration of absorbability If the article is applied to the human body, it is preferred to use natural flavors derived from plants.

Further, in the absorbent article of the present invention, the field to which the liquid fragrance (second fragrance) is applied (the fragrance application field) is not limited to the above-described form (the extension in the long axis direction of the absorbent layer is described above). field of the end portion of the strip), referred to before may be applied to the absorbent sheet S _a (absorption layer) of any place, but the above effect is obtained as this point of view, the former referred to the Department of the absorbent sheet S _a (absorption layer) The end field in the width direction or the long axis direction is preferable.

In the absorbent article of the present invention, the position at which the absorbent sheet (absorbent layer) is disposed is not particularly limited, and may be disposed on the skin facing side or the non-skin facing side of the cyclodextrin-containing layer or The location of both sides. For example, if the aforesaid absorbent sheet is disposed on the non-skin opposing side of the pre-recorded cyclodextrin-containing layer, the body fluid such as urine discharged from the wearer first comes into contact with the ring in the cyclodextrin-containing layer. The dextrin then reaches the pre-absorbent sheet, so the pre-recorded body fluid is exposed to the cyclodextrin earlier, and the chance of the precursor fluid contacting the cyclodextrin is fully ensured. As a result, the cyclodextrin has the spice. The release function or the deodorization function can be used at the same time, and these functions can be fully utilized.

In the light incontinence pad 1 of the present embodiment, the cyclodextrin-containing layer contains at least a part of the cyclodextrin containing the cyclodextrin in the absorbent layer 4, and is bonded to the non-skin of the cyclodextrin. A hot-melt type adhesive which is continuous or intermittently stretched along the long-axis direction D _{L of} the light incontinence pad 1 (absorbent article) on the facing front side sheet 5' (cyclodextrin holding sheet) Even the pre-recorded cyclodextrin-containing layer has an adhesive coating field T _H and a pre-cyclodextrin which are stretched in the long-axis direction D _L and the width direction D _W of the light incontinence pad 1 in planar projection. The field of the configuration, and the cyclodextrin configuration field T _C extending in the long axis direction D _L and the front width direction D _W ; the front end of the cyclodextrin configuration field T _{C is} preceded by the two ends of the long axis direction D _L E _LC , E' _LC and the two end edges E _WC and E' _WC in the width direction D _W are respectively located at the opposite ends E _LH in the long axis direction D _L before the T ₂ coating area. E 'E _WH end edges of the front and _LH referred widthwise direction D _W, E' _WH, the former referred to the long axis direction D _L and the width of the front remember To a position close to the D _W but also the inner side, it is configured.

Here, the term "adhesive application field" as used herein means the field in the plane projection to which the adhesive is applied, specifically, in the long axis direction D _L and the width direction D _W of the absorbent article. the extended field, and as being: then the outer most end portion is located on the front side of the agents referred to the width direction D _W, on both sides of the former referred to the long axis direction D _L respectively referred to the front along the long axis direction D _L and connected to each The two long-axis imaginary straight lines and the end portions of the adhesive on the outermost side in the long-axis direction D _L are connected to each other along the front width direction D _W on both sides in the front width direction D _W . The two width directions are imaginary straight lines that surround the field. In addition, in FIG. 3, two imaginary straight lines of the long axis direction and two imaginary straight lines of the width direction of the front are described, and only the portion (line segment) in which the adhesive application region T _{H is} divided is shown as an adhesive coating. The field T _{H is} preceded by the two end edges E _WH , E′ _WH in the width direction D _W and the two end edges E _LH , E′ _LH on the long axis direction D _L .

In the adhesive application field T _H , from the viewpoint of the contact efficiency between the body fluid discharged from the wearer and the cyclodextrin, as shown in FIG. 3, in the plane projection, the absorption is absorbed in the width direction D _W . The central axis C _L extending in the long axis direction D _L of the article extends in the width direction D _W while crossing the center extending in the width direction D _W of the absorbent article in the preceding long axis direction D _L The field in which the axis C _W extends in the longitudinal direction D _L is preferably in the field of overlapping with the body fluid absorption field T _{A of the} absorbent article, and is more preferably included in the field in which the precursor body fluid absorption region T _{A is} included.

In addition, in the present specification, the "cyclodextrin disposition field" means a field in which a cyclodextrin is placed in a planar projection on a surface of a pre-recorded cyclodextrin-preserving sheet, and specifically, The field extending in the axial direction D _L and the front width direction D _W is: the end portion of the cyclodextrin located on the outermost side in the width direction D _W in the front, respectively on the two sides of the long axis direction D _L 2 formed by connecting the major axis direction referred to the longitudinal direction D _L first imaginary straight line, and an end portion located at the most outer side of the cyclodextrin is referred to the front longitudinal direction D _L, referred to before the widthwise direction D _W Two imaginary straight lines in the width direction connected to each other in the width direction D _W in the front, and the surrounding area. In addition, in FIG. 3, two imaginary straight lines of the long axis direction and two imaginary straight lines of the width direction of the front are described, and only the portion (line segment) in which the cyclodextrin arrangement field T _{C is} divided is shown as a ring paste. The fine-arranged field T _{C is} preceded by the two end edges E _WC and E' _WC in the width direction D _W and the two end edges E _LC and E' _LC on the long-axis direction D _L .

The cyclodextrin disposition area T _C is obtained from the viewpoint of the contact efficiency between the body fluid discharged from the wearer and the cyclodextrin, and the like, as shown in FIG. C _L across the central axis _L extends on the major axis direction of the absorbent article of the _W and D extending in the width _W direction D, at the same time, across the width direction of the absorbent article of the D _W D _L in the longitudinal direction The field in which the central axis C _{W is} extended and extends in the long-axis direction D _L is preferably in the field of overlapping with the body fluid absorption field T _A before the absorbent article, and is the field in which the pre-recorded body fluid absorption field T _{A is} included. It is more ideal. When the cyclodextrin distribution field T _C is a field in which the body fluid absorption field T _A of the absorbent article is included, the body fluid which is discharged from the wearer can easily come into contact with the cyclodextrin, and the cyclodextrin can be more reliably exhibited. The smoothing function or deodorizing function of the fragrance.

In the present embodiment, the light incontinence pad 1 is a cyclodextrin in a cyclodextrin-containing layer, and is a carrier sheet 5' which is partially bonded to a tissue or the like by a pre-filling agent (cyclodextrin-maintaining sheet). And, in the planar projection, the front end of the cyclodextrin configuration field T _{C is} preceded by the two end edges E _LC , E' _LC in the long axis direction D _L and the two end edges E _WC , E on the pre-width direction D _W ' _WC ' is the two end edges E _LH , E' _LH in the long axis direction and the two edges E _WH and E' _WH in the front width direction D _W before the T _H coating area. Since the long axis direction D _L and the front width direction D _W are closer to the inner side than the inner side, since the cyclodextrin is held in the portion of the front body sheet 5' by the adhesive, the front ring paste is used. It is difficult for the cyclodextrin contained in the absorbent layer 4 to move forward in the direction of the surface of the body sheet 5', and the cyclodextrin is not held in the portion of the front sheet 5' of the front sheet, although the ring is pre-recorded. The dextrin containing the cyclodextrin in the absorbent layer 4 is movable to a certain extent in the direction of the front sheet 5', but By the edges E are located at the both ends of the referred _LC long axis direction D _L configuration prior art cyclodextrin T _C, E 'E _WC both end edges on the _LC and the front widthwise direction denoted D _W, E' _WC also outwardly The adhesive on the side of the front makes it difficult to move to the outside side. Thus, a light incontinence pad 1 according to the present embodiment, the cyclodextrin can contain cyclodextrin-based layer within the residence within specified before being referred to the field of applied adhesive adhesive T _H, which can effectively prevent partial cyclodextrin shift. As a result, in the light incontinence pad 1 of the present embodiment, the body fluid such as urine discharged from the wearer can be surely brought into contact with the cyclodextrin, so that the fragrance of the cyclodextrin can be released or The deodorizing function (the adsorption function of the odor component) is stably and fully exerted.

Further, in the present embodiment in a light incontinence pad, although having: cyclodextrin arranged art referred mind before T _C prior to the end edges of the long axis direction D _L E _LC, E _'LC referred to before and the widthwise direction D _W both edges E _WC, E _'WC, is located prior art coating agent T _H E _LH end edges that are on the long axis direction, E is then referred to the previous' E _WH end edges of the front and _LH referred widthwise direction D _W E' _WH is a structure closer to the inner side than the front side in the long axis direction D _L and the front width direction D _W. However, the absorbent article of the present invention is not limited to such a configuration, and has only the front ring. prior art configuration dextrin T _C E _LC end edges that are on the long axis direction D _L, E 'E _WC both end edges on the front or _LC referred widthwise direction D _W, E' according to any one of _WC, is then referred to the previous The coating application area T _{H is} preceded by the two end edges E _LH , E′ _LH in the long axis direction or the two end edges E _WH , E′ _WH in the front width direction D _W , in the long axis direction D _L or the front width direction. D _W is also close to the inner side of the structure. Even with such a configuration of the absorbent article, still within the cyclodextrin cyclodextrin layer containing a certain extent be retained in the predetermined adhesive before applying adhesive note art T _H, can be sufficiently prevented cyclodextrin Fine offset.

As described above, in the light incontinence pad 1 of the present embodiment, the cyclodextrin-containing layer has a cyclodextrin containing a mixture of a cyclodextrin for retaining the first fragrance and a precursor absorbent polymer and a precursor retaining substance. The absorbent material layer 4 is a structure in which the carrier sheets 5, 5' made of two liquid-permeable sheets are sandwiched. However, in the absorbent article of the present invention, at least the first fragrance is contained. The layer of the cyclodextrin may be, and is not limited to the above structure. For example, the cyclodextrin-containing layer may be a cyclodextrin of any form such as a powder or the like, and a liquid-repellent material and/or a precursor retaining substance may be added together as needed. The sheet is folded and sandwiched, or surrounded by three or more liquid permeable sheets, or one liquid permeable sheet (cyclodextrin coated sheet) as described in the second embodiment to be described later. The non-skin opposite side is covered and constructed. Moreover, when a plurality of liquid-permeable sheets are used as a carrier sheet, the liquid-permeable sheets of the same type may be used for the liquid-permeable sheets, and different types of liquid-permeable sheets may be used.

In the liquid permeable sheet used for the carrier sheet, for example, any sheet-like fibrous structure such as a nonwoven fabric (including a tissue) or a woven fabric made of an aggregate of fine fibers such as pulp can be used. The basis weight of the fiber structure is not particularly limited, but is, for example, from 1 to 50 g/m ² , preferably from 5 to 30 g/m ² , from the viewpoint of liquid permeability or prevention of outflow of cyclodextrin, and the like. Ideally 10~20g/m ² .

Further, the pre-recorded fiber structure has a degree that allows the body fluid discharged from the wearer to penetrate, and does not allow the cyclodextrin to pass through the constituent fibers of the fiber structure and flows out from the pre-recorded cyclodextrin-containing layer (for example). The interfiber distance is smaller than the particle diameter of the cyclodextrin powder described later. For example, a fiber structure in which the interfiber distance of 1 to 300 μm is 90% or more of the total fiber structure is preferable, and a fiber structure having an interfiber distance of 10 to 150 μm is preferably 90% or more of the total fiber structure. .

Here, the fiber-to-fiber distance of the fiber structure is measured by a mercury porosimetry (JIS R 1655), and can be measured using a mercury porosimeter (manufactured by Shimadzu Corporation). In the mercury intrusion method, when mercury is pressed between the constituent fibers of the fiber structure which is the object to be measured, the pressure applied to the mercury and the space between the constituent fibers extruded into the fiber structure are measured. Information about the structure of the pre-recorded fiber structure can be obtained from the volume of mercury in the interior.

Specifically, the fiber-to-fiber distance of the fiber structure can be measured by a mercury porosimeter according to the following procedure.

1) The fiber structure of the object to be measured was cut into 24 mm × 15 mm to prepare a sample for measurement. Three samples were prepared by using this sample for measurement.

2) Set three samples for measurement so that they do not overlap each other After the sample cell of the mercury porosimeter (manufactured by Shimadzu Corporation), the pressure applied to the mercury is gradually changed, and the space between the constituent fibers extruded into the fiber structure (that is, the pores) is measured. The volume of mercury in the inside (ie, the pore volume). Further, the measurement was carried out in an environment of 22 ° C and 65% RH.

Further, in the light incontinence pad 1 of the present embodiment, the cyclodextrin contains a layer, and the cyclodextrin contains the cyclodextrin in the absorbent layer 4, The carrier sheet 5' formed on the thin paper or the like disposed on the non-skin opposing side of the cyclodextrin is partially joined by the adhesive, but in the absorbent article of the present invention, the cyclodextrin The form of bonding to the carrier sheet (liquid permeable sheet) is not limited to such a form. For example, the cyclodextrin may be bonded to the liquid permeable sheet disposed on the opposite side of the skin of the cyclodextrin. Further, it can be noted that the cyclodextrin is bonded to the liquid permeable sheet disposed on both the skin facing side and the non-skin facing side of the cyclodextrin.

Here, the cyclodextrin is a cyclic oligosaccharide in which a glucopyranose unit is linked by α-1,4 bonding, and generally, a glucopyranose unit contained in one molecule of a cyclodextrin The number is 6 for α-cyclodextrin, 7 for β-cyclodextrin, and 8 for γ-cyclodextrin. The cyclodextrin may be composed of other molecules (for example, an active ingredient such as a fragrance or a deodorant component, an odor component of excrement, etc.) on the inside of the ring structure due to the presence of moisture or the like, and may be Other molecules in the cage are released as the environment changes. The cyclodextrin to be used in the absorbent article of the present invention is not particularly limited, and may be chemically modified in addition to α-, β-, γ-cyclodextrin and/or a mixture of these ( For example, methylated or ethylated α-, β-, γ-cyclodextrin and/or mixtures of these, and the like. Further, in the absorbent article of the present invention, the "cyclodextrin" includes a cyclodextrin which does not contain a cyclodextrin, and a cyclodextrin which retains various active ingredients such as a fragrance.

In the absorbent article of the present invention, the cyclodextrin is used as a cyclodextrin which is a first fragrance which is formed by any of natural flavors such as natural flavors and synthetic flavors. Such a cyclodextrin that retains the fragrance has When the body fluid of the urine discharged by the wearer comes into contact, the function of the fragrance maintained by the cyclodextrin is gradually released, so that the fragrance of the pre-recorded body liquid can be covered by the fragrance which is discharged, and at the same time, by The un-caged cyclodextrin after the fragrance is released can adsorb an odor component such as an ammonia component contained in the precursor liquid. Therefore, when such a cyclodextrin which retains a fragrance is used, the odor generated by the body fluid such as urine discharged from the wearer can be effectively suppressed. In addition, the cyclodextrin which retains the fragrance includes, in addition to the caged complex which is contained in the inner side of the ring structure of the cyclodextrin molecule, and includes various intermolecular forces or intermolecular interactions. And the cyclodextrin molecule and the fragrance will be combined.

In the absorbent article of the present invention, the first fragrance to be held by the cyclodextrin is not particularly limited, and any of natural flavors such as natural flavors and synthetic flavors which have been conventionally known can be used, but it is considered that the absorbent article is For the human body, it is preferred that the first fragrance is a natural spice derived from plants. Moreover, it is preferable that the first fragrance held by the cyclodextrin is the same as the liquid fragrance (second fragrance) applied to the absorbent layer. When the first fragrance and the second fragrance are the same component, even if the body fluid such as urine discharged from the wearer comes into contact with the cyclodextrin holding the first fragrance, the first fragrance is released from the cyclodextrin. There is no change in the flavor due to the mixing of the different flavors produced by the individual flavors, and there is no unpleasant aroma due to the blending of the plurality of flavors. Even when the body fluid such as urine is discharged from the wearer, in addition to the fragrance due to the liquid fragrance (second fragrance), the fragrance derived from the first fragrance released from the cyclodextrin is generated, so that it is absorbed from the former. The scent of sexual products will be increased Strong, it can cover the odor of the pre-recorded body fluid more strongly.

Even in the absorbent article of the present invention, if the unfed cyclodextrin (the cyclodextrin which does not retain the fragrance) and the cyclodextrin which retains the first fragrance of the first fragrance are used in combination, the above-mentioned retention is maintained. 1 The effect of the cyclodextrin of the fragrance can also ensure a certain amount of un-caged cyclodextrin in the absorbent article, so that the odor component caused by the unfed cyclodextrin can be more reliably exhibited. The adsorption effect can further increase the deodorizing effect of the absorbent article. Further, the cyclodextrin which is not caged is preferably used in a ratio of 5 to 50% by mass based on the total amount of the cyclodextrin to be used.

The form of the cyclodextrin to be used in the absorbent article of the present invention is not particularly limited, and various forms can be used. However, from the viewpoint of dispersibility, ease of handling during production, and improvement of urine discharged from the wearer, etc. From the viewpoint of the contact efficiency of the body fluid, etc., it is preferred to use a bond of maltodextrin cyclodextrin, amylopectin or gum arabic to adjust the particle size of the cyclodextrin powder. The particle size of the cyclodextrin powder is not particularly limited, and may be, for example, about 5 μm to 300 μm, preferably 10 μm to 100 μm, but has a carrier sheet (liquid permeable sheet) adjacent to the front ring cyclodextrin. It is particularly preferable that the fiber structure has a large particle diameter between fibers. When the particle diameter of the cyclodextrin powder is larger than the fiber-to-fiber distance of the fiber structure constituting the front-form sheet, it is possible to prevent the cyclodextrin powder from passing through the constituent fibers of the fiber structure before the ring paste. Since the fine-containing layer flows out, it is possible to stabilize the slow-release function or the deodorizing function of the fragrance of the cyclodextrin, and to make it fully exerted.

In addition, the particle diameter of the cyclodextrin powder may be dry laser diffraction scattering by, for example, a laser diffraction/scattering particle size distribution measuring apparatus (for example, Microtrac MT3300EXII manufactured by Nikkiso Co., Ltd.). Determined by law. In the dry laser diffraction scattering method, the powder sample is dispersed by air, and the sample is irradiated with laser light, and the volume-based particle diameter distribution is measured from the diffraction pattern, and in the present specification, The median diameter (D50) obtained from the particle diameter distribution is used as the particle size of the pre-recorded powder. The specific measurement conditions caused by the dry laser diffraction scattering method are as follows.

Further, the cyclodextrin powder may be a small amount of a cyclodextrin which retains the first fragrance and an un-caged cyclodextrin, and may contain a small amount of any active ingredient such as a deodorant component. Any functional component (for example, 10% by mass or less) such as cyclodextrin, and/or a bond or an absorbent component (for example, a pulp or an absorbent polymer) or an adsorbing component (for example, zeolite, silicone, or activated carbon). . The pre-recorded active ingredient system is exemplified For example, a deodorizing component, an antibacterial component, a mixture of these, and the like which have been known in the past. Such a cyclodextrin which retains an active ingredient is contained in addition to a caged complex which is preceded by a ring-shaped structure of a cyclodextrin molecule and which has a pre-recorded active ingredient, and includes various intermolecular forces or intermolecular The interaction between the cyclodextrin molecule and the pre-reactive active ingredient is achieved by interaction or the like.

The cyclodextrin (i.e., cyclodextrin complex) which retains the active ingredient of the former has a cyclodextrin in contact with moisture contained in a body fluid such as urine discharged from a wearer. The active ingredient is kept released, so that the function of the active ingredient can be exhibited. Such a cyclodextrin complex can be easily obtained by, for example, adding a fragrance or an active ingredient to a solution containing an uncased cyclodextrin and stirring and mixing it. Further, the presence or absence of the cyclodextrin cage can be confirmed by elemental analysis using X-ray or the like.

In the cyclodextrin disposition configuration, the method of disposing the cyclodextrin on the surface of the adhesive which has been applied to the pre-formed sheet is not particularly limited, and the state of the above-mentioned powder ore can be maintained directly. The arrangement may be carried out by dispersing it in a state of a dispersion medium (for example, polysiloxane oil, mineral oil, etc.), or may be dissolved in a solvent (for example, propylene glycol, dipropylene glycol, and 1,3-butylene glycol). It is disposed in a state of a solution of a glycol such as a glycol or an ester organic solvent such as triethyl citrate or diethyl phthalate.

Further, in the cyclodextrin disposition configuration, the means for disposing the cyclodextrin of the first fragrance is not particularly limited. For example, a non-contact or contact type coater can be used, and a spray or a plurality of ribs can be used. It is applied in any form such as a shape or an Ω shape. Cyclodextrin before mind, based on the projection plane, without coating gap can be arranged in the art T _C cyclodextrin, the cyclodextrin may be formed in a plurality arranged art T _C is not present in the field of cyclodextrin (also That is, the cyclodextrin does not exist in the field). In particular, the cyclodextrin arrangement field T _C contains an overlapping field overlapping with the body fluid absorption field T _{A of the} absorbent article, and is preferably applied in such a manner that a plurality of cyclodextrins do not exist in the overlapping region. Once such a cyclodextrin is not present, the field can function as a passage for bodily fluids such as urine discharged from the wearer. Therefore, the pre-recorded body fluid is not hindered by the cyclodextrin containing the absorbent layer. The direction of the thickness D _{T of the} absorbent article is gradually saturated. As a result, the absorbent article of the present invention exhibits a deodorizing function and excellent absorption performance.

When the content of the absorbent polymer is 60 parts by mass or less in the cyclodextrin-containing absorbent layer, the body fluid which is not absorbed by the absorbent polymer is likely to be present, so that it can be in contact with the cyclodextrin. The amount of the body fluid and the contact time are increased. When the content of the liquid retaining substance is 40 parts by mass or more, the body fluid easily spreads over a wide range by the capillary phenomenon of the precursor retaining substance. The precursor fluid is contacted with the cyclodextrin over a wide range.

When the adhesive is applied in such a flat coating form, the adhesive is immersed in the constituent fibers of the fiber structure constituting the front-end cyclodextrin-retaining sheet to fill the voids in the fiber structure, and thus has been pre-recorded as a cyclodextrin. Keeping the cyclodextrin held by the sheet, it is difficult to penetrate the front liquid-permeable sheet and flow out from the cyclodextrin-containing layer, and at the same time, since the strength of the liquid-permeable sheet is increased, it is not easily broken when worn, and It is also difficult to produce heat shrinkage. As a result, in the absorbent article of the present invention, the structure of the cyclodextrin-containing layer can be stably maintained, so that the fragrance of the cyclodextrin contained in the layer containing the cyclodextrin can be deactivated or deodorized. The function is more stable and more effective. Further, as shown in the second embodiment to be described later, the cyclodextrin is an absorbent article that is bonded to the sheet on the opposite side of the skin of the cyclodextrin, as described above, if the adhesive is applied flat. When the sheet is held in the cyclodextrin, the cyclodextrin is prevented from maintaining the liquid permeability of the sheet because of the adhesive agent, which is not preferable.

Further, in the absorbent article of the present invention, the amount of the adhesive to be applied is not particularly limited, and may be appropriately set depending on the desired strength, liquid permeability, deodorizing performance, etc., and may be, for example, 1 to 40 g. /m ² , the ideal system is 2 to 20 g/m ² , and more preferably 4 to 10 g/m ² .
