Hereinafter, the present invention will be described based on its preferred embodiments with reference to the drawings. In the following description of the drawings, the same or similar reference numerals are given to the same or similar parts. The drawings are basically schematic, and the ratio of each dimension may be different from the actual one.

1-3, the sanitary napkin 1 which is one Embodiment of the absorbent article of this invention is shown. The napkin 1 has a longitudinal direction X corresponding to the front-back direction of the wearer, that is, a direction extending from the abdomen side to the dorsal side through the crotch portion, and a lateral direction Y orthogonal to the longitudinal direction X, and absorbs body fluid. A possible absorber 5 is provided.
The napkin 1 may include, as the absorbent body 5, a sheet type absorbent body 5A shown in FIG. 2 or a laminated fiber type absorbent body 5B shown in FIG. The description of the absorber 5 described below applies to both the absorbers 5A and 5B unless otherwise specified.

The napkin 1 is provided on the side farther from the wearer's skin than the absorber 5, and includes a backsheet 4 that forms the non-skin facing surface Sb of the napkin 1. More specifically, the napkin 1 is arranged on the absorber 5, the backsheet 4 arranged on the non-skin-facing surface side of the absorber 5, and the side closer to the wearer's skin than the absorber 5. , The top sheet 3 forming the skin-facing surface Sa of the napkin 1. The top sheet 3 is a member that can come into contact with the skin of the wearer when the napkin 1 is worn, and is typically liquid-permeable. On the other hand, the back sheet 4 is typically liquid impermeable, liquid impermeable, or water repellent (in short, leakproof).
The skin-facing surface Sa and the non-skin-facing surface Sb of the napkin 1 are both outermost surfaces of the napkin 1. When the napkin 1 is worn, the skin-facing surface Sa can contact the wearer's skin, and the non-skin-facing surface Sb is located on the opposite side of the skin-facing surface Sa.

In the present specification, the “skin-facing surface” is a surface of the absorbent article or a constituent member thereof (for example, the absorbent body 5) that faces the skin side of the wearer when the absorbent article is worn, that is, relative to the wearer's skin. The "non-skin facing surface" is a side that is opposite to the skin side when the absorbent article is worn, that is, the side that is relatively far from the skin of the wearer. It is a surface to be treated. The term "when worn" as used herein means a state in which the normal proper wearing position, that is, the correct wearing position of the absorbent article is maintained.

The napkin 1 is arranged in the crotch portion of the wearer and includes a vertical central region M including an excretory portion facing portion (not shown) facing the excretory portion such as the vaginal opening of the wearer, and is worn more than the vertical central region M. It is divided into three regions, a front region F arranged on the front side (abdominal side) of the wearer and a rear region R arranged on the rear side (back side) of the wearer with respect to the longitudinal center region M.

The napkin 1 has a pair of wings 2W, 2W on both sides in the lateral direction Y with the absorber 5 interposed therebetween. The wing portion 2W is configured to include the backsheet 4. More specifically, as shown in FIG. 1, a pair of side flap portions 2S, 2S extend outward in the lateral direction Y from both side edges of the absorbent body 5 along the longitudinal direction X, and further, in the longitudinal central region M. , The side flap portion 2S extends outward in the lateral direction Y more than the peripheral portion, and a pair of wing portions 2W, 2W are provided on the left and right sides along the longitudinal direction X of the absorbent main body portion 2 in the longitudinal central region M. It has been extended. The wing part 2W is provided with a wing part adhesive part (not shown) as a fixing means for fixing the wing part 2W to clothes such as shorts on the non-skin facing surface. Since the wing portion 2W is used by being folded back toward the non-skin facing surface (outer surface) side of the crotch portion of clothing such as shorts, the non-skin facing surface of the wing portion 2W, which is the surface on which the wing adhesive portion is formed, is , When it is used, it faces the wearer's skin side and becomes the skin-facing surface (see FIG. 6). Further, a fixing means for fixing the napkin 1 to clothes such as shorts on the non-skin facing surface of the absorbent main body 2, that is, the non-skin facing surface of the back sheet 4, which is a region sandwiched between the side flaps 2S, 2S. The main body adhesive section 10 is provided. The wing adhesive section and the main body adhesive section 10 are each covered with a release sheet (not shown) made of film, non-woven fabric, paper or the like before use.

In the present invention, the vertical center area of an absorbent article having no wing portion (for example, a typical disposable diaper) corresponds to an intermediate area when the absorbent article is divided into three parts in the vertical direction. ..

In the napkin 1, the second sheet 6 is arranged between the top sheet 3 and the absorber 5. The second sheet 6 is a sheet that is separate from the top sheet 3 and the absorbent body 5, and is a sheet that is also called a sublayer sheet in the technical field, and is partially attached to the top sheet 3 and/or the absorbent body 5 by an adhesive or the like. Is joined to.

As shown in FIGS. 2 and 3, the top sheet 3 and the second sheet 6 cover the entire area of the skin-facing surface of the absorbent body 5, and further extend from both side edges along the vertical direction X of the absorbent body 5 in the lateral direction Y. It is extended to. On the other hand, the back sheet 4 covers the entire non-skin-facing surface of the absorbent body 5, and further extends outward in the lateral direction Y from both side edges of the absorbent body 5 along the longitudinal direction X. The extension length of the back sheet 4 from the side edge of the absorber 5 is longer than the extension length of the top sheet 3 and the second sheet 6 from the side edge of the absorber 5. The back sheet 4 and the side sheet 7 are joined to each other at a portion extending from both side edges of the absorbent body 5 along the longitudinal direction X by a known joining means such as an adhesive, heat sealing, or ultrasonic sealing. The side flap portion 2S is a portion of a member of the napkin 1 that extends outward from the absorbent body 5 (absorbent body portion 2) in the lateral direction Y. In the illustrated form, the top sheet 3 and the second sheet 6 are provided. , The side seat 7 and the back seat 4 are included.

In the napkin 1, the absorbent main body portion 2 has a skin-facing surface (skin-facing surface of the top sheet 3) on both side portions along the vertical direction X so as to overlap with left and right side portions along the vertical direction X of the absorbent body 5 in a plan view. In addition, the pair of side sheets 7, 7 are arranged over substantially the entire length of the absorbent main body 2 in the vertical direction X. The pair of side sheets 7, 7 are joined to other members such as the top sheet 3 by known joining means such as an adhesive at linear joining portions (not shown) extending in the vertical direction X. The side sheet 7 forms the skin-facing surface Sa of the napkin 1 together with the top sheet 3.

As the above-mentioned members constituting the napkin 1, those generally used in this type of absorbent article can be used without particular limitation, provided that they are in accordance with the later description of the members. .. As the top sheet 3, for example, a known non-woven fabric having a single layer or a multi-layer structure having liquid permeability can be used. As the back sheet 4, a sheet having a leakproof property, that is, liquid impermeable (a property that does not allow liquid to pass through) or liquid impermeability (a property that does not allow liquid to pass though it cannot be said to be liquid impermeable). A sheet having the same can be used, and examples thereof include a moisture-permeable resin film. As the second sheet 6, a sheet that can be used as the top sheet 3 can be used. As the side sheet 7, a water repellent or water repellent non-woven fabric can be used.

As shown in FIG. 1( a ), the napkin 1 includes an absorber 5 and members (top sheet 3 and second sheet 6 in the illustrated embodiment) arranged on the skin-facing surface side of the absorber 5. 5 has a skin-side recessed portion 8 integrally recessed on the non-skin facing surface side (back sheet 4 side). The skin-side recessed portion 8 does not penetrate through the absorbent body 5 in the thickness direction, has an opening on the skin-facing surface of the top sheet 3, and has a bottom portion inside the absorbent body 5 on the side opposite to the opening. The skin-side recessed portion 8 has a function of inhibiting movement of body fluid such as menstrual blood in the surface direction. In the illustrated form, the skin-side recessed portion 8 has a linear shape that extends in one direction in a plan view, and the skin-side recessed portion 8 as a whole has an annular shape that is closed in a plan view. The skin-side recessed portion 8 is formed at least in the vertical center region M.

In the napkin 1, as shown in FIG. 1B, the absorbent body 5 has a non-skin side concave portion 9 on the non-skin facing surface of the absorbent body 5. As shown in FIG. 2, the backsheet 4 is not joined to the absorbent body 5 at the non-skin side recessed portion 9, but is joined to the absorber 5 at a portion other than the non-skin side recessed portion 9 via the adhesive 11. Has been done. The non-skin side recessed portion 9 does not penetrate the absorbent body 5 in the thickness direction, has an opening on the non-skin facing surface of the absorbent body 5, and has a bottom portion on the side opposite to the opening inside the absorbent body 5. Have. The non-skin side recessed portion 9 is arranged at a position overlapping the skin side recessed portion 8 in a plan view. In the illustrated form, the non-skin-side recessed portion 9 has the same planar view shape as the skin-side recessed portion 8.

Each of the recessed portions 8 and 9 is formed by a known pressing process, and can be referred to as a “pressing part” from the forming method. The recessed portions 8 and 9 which are the compressed portions have a higher density than the peripheral non-compressed portions. In the absorber 5, a high-density portion that overlaps the recessed portions 8 and 9 in a plan view and a low-density portion where the recessed portions 8 and 9 are not formed coexist. There is a density difference in the surface direction between the skin facing surface and the non-skin facing surface side.

The absorber 5 will be described. The absorber 5 forms the main body of the absorbent main body 2, and the contour of the absorbent body 5 in plan view forms the contour of the absorbent main body 2 in plan view. The absorber 5 extends in the longitudinal direction X from the front region F through the longitudinal center region M to the rear region R.

FIG. 2 shows an absorber 5A that can be used as the absorber 5. The absorbent body 5A is an absorbent body mainly composed of an absorbent sheet which is a sheet-shaped absorbent body, and is thinner and more flexible than a laminated fiber type absorbent body 5B described later. The absorbent sheet is typically configured to include a fiber sheet mainly composed of a fiber material such as wood pulp, and a water absorbent material such as a water absorbent polymer fixed to the inside or the surface of the fiber sheet. ing. The absorbent sheet may have a structure in which particles of a water-absorbent polymer are interposed between two sheets facing each other. As the absorbent sheet, for example, those described in Japanese Patent No. 2963647 and Japanese Patent No. 2955223 can be used.

The absorbent body 5A covers the central absorbent sheet 50 arranged in the central portion of the napkin 1 in the lateral direction Y and the entire sheet 50, and forms the outer surface (skin-facing surface, non-skin-facing surface) of the absorbent body 5A. Main body absorbent sheet 51. Both the sheets 50 and 51 are the absorptive sheets.
In the illustrated form, both of the sheets 50 and 51 have a laminated structure formed by folding one sheet. The laminated structure of the central absorbent sheet 50 has shorter lengths in both the longitudinal direction X and the lateral direction Y than the laminated structure of the main absorbent sheet 51. Is arranged between the two folded sheets 51, 51. The contour of the laminated structure of the main body absorbent sheet 51 in plan view forms the contour of the absorber 5A in plan view. The central absorbent sheet 50 is arranged in the vertical central region M at the portion facing the excretion part. The arrangement portion of the central absorbent sheet 50 (the overlapping portion of both sheets 50, 51) is a thick portion having a larger thickness than the peripheral portion, and is raised on the skin side of the wearer of the napkin 1.

FIG. 3 shows an absorber 5B that can be used as the absorber 5. The absorbent body 5B is made by stacking a fiber material such as wood pulp, and covers the absorbent core 52 that is the main body of the absorbent body 5B and the outer surface (skin facing surface, non-skin facing surface) of the absorbent core 52. And a liquid-permeable core wrap sheet 53. The absorbent core 52 and the core wrap sheet 53 may be joined by an adhesive such as a hot melt adhesive. The absorbent core 52 may include a water-absorbent polymer in addition to the fiber material. For example, the absorbent core 52 may have a structure in which particles of the water-absorbent polymer are supported inside the aggregate of the fiber material. A sheet having liquid permeability can be used as the core wrap sheet 53, and is typically a nonwoven fabric or paper. The core wrap sheet 53 may be composed of only one sheet, or may be composed of a plurality of sheets.

When not in use, the napkin 1 is folded together with the packaging material 15 into an individual body 20 as shown in FIG. 4. FIG. 5 shows a state in which the individual packaging body 20 is partially expanded, and FIG. 6 shows a state in which the individual packaging body 20 is completely expanded.
On the non-skin facing surface Sb of the napkin 1, more specifically, on the non-skin facing surface of the back sheet 4 forming the non-skin facing surface Sb, a packaging material 15 for wrapping the napkin 1 is arranged. The packaging material 15 is detachably fixed to the back sheet 4 via the main body adhesive portion 10 (see FIG. 1B). As shown in FIG. 6, the individual packaging body 20 includes the absorbent main body 2 in a state in which the pair of wings 2W, 2W are bent toward the top sheet 3 side, together with the packaging material 15, two folding curves L1,. It is formed by folding the top sheet 3 inward in the vertical direction X at L2. At both side edge portions 20S, 20S along the longitudinal direction X of the individual packaging body 20, the two folded packaging materials 15, 15 constituting the side edge portion 20S are joined by heat sealing or the like.

The packaging material 15 has a transparent portion. The “transparent portion” here means a portion having a total light transmittance of preferably 70% or more, more preferably 90% or more. The transparent portion of the packaging material 15 may be colorless or colored. The entire packaging material 15 may be a transparent portion, or only a part thereof may be a transparent portion. The packaging material 15 forms the outer surface of the individual packaging body 20, and when the individual packaging body 20 is viewed from the outside, the color of the napkin 1 contained in the individual packaging body 20 is passed through the transparent portion of the packaging material 15. Can be seen.

In the present invention, "total light transmittance" refers to a value measured according to JIS K7361-1:1997. It can be evaluated that the higher the total light transmittance, the higher the translucency. The total light transmittance can be measured using a commercially available haze meter (for example, "HAZEMETER NDH 5000" manufactured by Nippon Denshoku Industries Co., Ltd.).

When the napkin 1 is folded together with the packaging material 15 into the individual packaging body 20, the packaging material 15 is located on the outer surface of the individual packaging body 20 and the end portion of the packaging material 15 is located at a predetermined position of the packaging material 15. A fastening member 16 is provided for fastening to the. As shown in FIG. 6, the fastening member 16 is fixed to one end of the packaging material 15 in the vertical direction X. The fastening member 16 has a rectangular shape in plan view, and its longitudinal direction coincides with the longitudinal direction X. One end 16a in the longitudinal direction of the fastening member 16 is a fixed end fixed to the packaging material 15, and the other end 16b is a free end not fixed to other members. An adhesive (not shown) is attached to the surface of the free end portion 16b of the fastening member 16 facing the packaging material 15 in the individual packaging body 20 (the surface opposite to the surface exposed in the individual packaging body 20). The free end portion 16b is provided so as to be detachably fixed to the packaging material 15 via the adhesive. The fastening member 16 functions as a sealing portion for the individual packaging body 20 in an unused state, and also as an opening picking portion that is pinched with fingers when opening the individual packaging body 20.

The napkin 1 includes 1) a purple region which is singularly visible in purple and is arranged to be visible to the user, and 2) one or more functional materials selected from the group consisting of a cooling sensation agent and an antibacterial agent. Is characterized by including.
The purple region of 1) is a region in which the color visually recognized when the region is directly viewed without any other member is purple. The term "purple" used in the present invention is a color in the CIE1976 (L ^* a ^* b ^* ) color system in which the chromaticity a ^* is 0 or more and the chromaticity b ^* is 0 or less.

The chromaticity a ^* and the chromaticity b ^* are indices of the hue and saturation of the color (for example, purple), respectively.
In the present invention, the chromaticity a ^* and the chromaticity b ^{* and the} later-described lightness L ^* and saturation C ^* are respectively the L ^* a ^* b ^* table standardized by the International Commission on Illumination (CIE) in 1976. It is based on a color system (CIE1976 (L ^* a ^* b ^* ) color system).
The chromaticity a ^* , the chromaticity b ^* , and the lightness L ^* are measured by using a commercially available color difference meter (for example, Handy Spectral Color Difference Meter NF333 (trade name) manufactured by Nippon Denshoku Industries Co., Ltd.) according to JIS Z 8781. It can be measured according to -4.

Regarding 1) above, purple is said to have an effect of healing the sadness and anger in the mind, and is used in a relaxing space or the like as a healing color that balances the mind and body. Purple is also a color that is preferred by artists, therapists, healers, etc. as it symbolizes spirituality and has the effect of increasing inspiration and broadening sensibility. A cold color (for example, blue) makes the viewer feel cold, while a warm color (for example, red) makes the viewer feel warm, whereas purple is a neutral color, so the viewer feels cold or warm. It is difficult to recall such an extreme image. Since the purple region that brings such a psychological effect is visibly arranged for the user (wearer) in the napkin 1, the purple psychological effect is given to the user, and the napkin 1 is used before (for example, The user's depressive mood can be alleviated during the wearing of the napkin 1) and during use.

Regarding the above 2), since the napkin 1 contains the functional material, the napkin 1 is actually excellent in usability due to the function and effect exhibited by the functional material. Specifically, for example, when a cooling sensation agent is contained as a functional material, the action of the cooling sensation agent allows the user to perceive a refreshing feeling, a refreshing feeling, a dry feeling, etc. Is obtained. Further, when the antibacterial agent is contained as the functional material, the action of the antibacterial agent suppresses the generation of offensive odor caused by the body fluid, thereby obtaining a good usability.

Due to the synergistic effect of the combination of the above 1) and 2), the napkin 1 can exhibit a particularly remarkable effect that is not exhibited when the above 1) and 2) are adopted individually. That is, according to the above 1), the user of the napkin 1 is relaxed due to the psychological effect of the purple color before wearing the napkin 1, and the feeling of depression during menstruation is relieved. Since the napkin 1 is worn, it is possible to have a positive feeling, such as a feeling of trust and security, against the specific effect exerted by the above 2) while wearing the napkin 1, and as a result, It is easy to feel the effect of 2). In general, what is imaged in the brain can affect the human sense, and the napkin 1 can be used by the above 1) to wear the napkin 1 before wearing the napkin 1. By expecting a good feeling of use, it is possible to make it easier to perceive the effect of the above 2) while wearing.

In the absorbent article of the present invention, the purple region may be a white or achromatic member close to white (for example, the backsheet 4) partially or wholly colored by a known dyeing method such as printing, It may be composed of purple primary dyed fibers. The primary fiber is a fiber that is colored in the fiber manufacturing stage, and is manufactured through a coloring process, for example, in which a coloring matter such as a pigment is added to a manufacturing intermediate in the stages from resin manufacturing to fiberization.

The color of the constituent members of this type of absorbent article is usually white or an achromatic color close to white, and even in the absorbent article of the present invention, the color of the constituent members is white or close to white unless otherwise specified. It is achromatic.
In this specification, achromatic member close to white or white, the lightness L ^* is preferably 90 or more, more preferably be 92 or more, with respect to the chromaticity a ^* and chromaticity b ^* is compared with a purple member Te chromaticity a ^* is small, or the chromaticity b ^* or is larger than the purple member, or purple member is preferably greater ^* chromaticity a ^* is smaller and chromaticity b compared to.
The chromaticity a ^* of a white or achromatic member close to white is preferably -1 or more and 1 or less, preferably -0.5 or more and 0.5 or less, more preferably the lower limit value is 0 or less, and the chromaticity b ^* Is preferably -1 or more and 4 or less, preferably 0 or more and 3.5 or less.

In the absorbent article of the present invention, the purple region is arranged to be visible to the user. The term “visiblely arranged” as used herein means that at least a part of the purple region can be visually recognized when the absorbent article is viewed from the outside without being broken by disassembling the absorbent article. In the present invention, it suffices that the purple region is arranged so as to be visible to the user, and the constituent member of the absorbent article having the purple region is not particularly limited. Further, a part or all of one constituent member may be a purple region. For example, when a part of the backsheet 4 which is one of the constituent members of the napkin 1 is a purple region, a part of the backsheet 4 in the plane direction may be a purple region, and the backsheet 4 has a thickness direction. A part (for example, one of the skin facing surface side and the non-skin facing surface side) may be a purple region. Moreover, in the absorbent article, a plurality of constituent members may have a purple region. Examples of the member that can be a member having a purple region in the napkin 1 (hereinafter, also referred to as “purple member”) include the top sheet 3, the back sheet 4, the absorber 5, the second sheet 6, and the side sheet 7.

In the illustrated form, the back sheet 4 is configured to include a purple region, and the back sheet 4 is a purple member. The backsheet 4 may be entirely in the purple region, a part thereof may be in the purple region, and the other part may be in a color other than purple. In the illustrated form, the former is adopted, and the entire backsheet 4 is visible in purple. The back sheet 4 is a member that is disposed in the vicinity of the packaging material 15 that forms the outer surface of the individual packaging body 20 when the napkin 1 is the individual packaging body 20 shown in FIG. It is a member that is easily visible from the outside. If such a backsheet 4 is purple, a series of mounting operations before using the napkin 1, that is, “opening the individual body 20, opening the part shown in FIG. Then, in a series of wearing operations of wearing the napkin 1 on the crotch portion, the user can surely visually recognize and recognize the purple color, so that the psychological effect brought about by the purple color described above can be more reliably exhibited.

Further, as described above, the packaging material 15 forming the outer surface of the individual packaging body 20 has a transparent portion, and when the individual packaging body 20 is viewed, the color of the napkin 1 can be visually recognized through the transparent portion. The purple region of the purple member (backsheet 4) can be visually recognized through the transparent portion. Therefore, the purple color can be visually recognized not only when the napkin 1 is mounted but also when the individual body 20 is carried, and the psychological effect brought by the purple color can be more reliably exhibited.

In the napkin 1, the purple region of the backsheet 4, which is a purple member, is visible when the non-skin facing surface Sb of the napkin 1 is viewed as shown in FIG. As shown, when the skin-facing surface Sa of the napkin 1 is viewed, it is visible at least in the non-arrangement region of the absorber 5 on the skin-facing surface Sa (the region that does not overlap with the absorber 5 in plan view). Since the back sheet 4 forms the non-skin facing surface Sb of the napkin 1, if the back sheet 4 has a purple area, the purple area is visible when the non-skin facing surface Sb is viewed. Of course. On the other hand, on the skin-facing surface side of the backsheet 4, since other members such as the absorber 5 are laminated so as to cover the backsheet 4, depending on the arrangement state of the other members, the napkin 1 In some cases, the purple area of the backsheet 4 may not be visible when the skin-facing surface Sa is viewed. In particular, since the absorber 5 has a relatively large thickness and poor light transmissivity, there is a possibility that the purple region of the backsheet 4 may not be visible when the skin facing surface Sa of the napkin 1 is visually observed in the region where the absorber 5 is arranged. However, in the non-arranged region of the absorber 5, one or several sheets of non-woven fabric or the like having a relatively small thickness and a high light transmittance (for example, the top sheet 3, the side sheet 7, the second sheet 6) are usually stacked. Therefore, the purple region of the backsheet 4 can be sufficiently visually recognized when visually inspecting the skin-facing surface Sa of the napkin 1.

The side flap portion 2S including the wing portion 2W can be exemplified as a portion where the absorber 5 is not arranged in the napkin 1, that is, a portion in which the purple region of the backsheet 4 can be visually recognized on the skin facing surface Sa of the napkin 1. In particular, as shown in FIGS. 2 and 3, in the wing portion 2W, only one side sheet 7 made of a nonwoven fabric or the like is arranged on the skin-facing surface of the back sheet 4, so that the skin-facing surface Sa of the napkin 1 is disposed. In the visual inspection, the purple area of the backsheet 4 can be sufficiently visually recognized.

In the napkin 1, as shown in FIG. 1, when the absorbent body non-arrangement region 5N extends in the vertical direction X between the wing portion 2W and the absorbent body 5, the skin facing surface Sa of the napkin 1 is visually observed. When this is done, the purple region of the purple member (backsheet 4) is visible in the wing portion 2W and the absorber non-arrangement region 5N, and the absorber non-arrangement region 5N is more visible than the wing portion 2W. The chromaticity a ^* of the stored color is small and the chromaticity b ^* is large. When the napkin 1 is attached to clothes such as shorts, an operation of bending the wing portion 2W to the non-skin facing surface Sb side in the absorber non-arrangement region 5N is usually performed while visually checking the skin facing surface Sa of the napkin 1. However, with the above configuration, the position of the absorbent body non-arrangement region 5N to be bent becomes clear, so that the bending operation of the wing portion 2W is facilitated and the operability of the napkin 1 is improved. obtain.

As described above, in the case of observing the skin-facing surface Sa of the napkin 1, and of "absorber blank region 5N" chromaticity a ^* chromaticity a ^{* <wing} portions 2W of the absorber blank region 5N "color As a method of establishing the magnitude relationship of the degree b ^* >the chromaticity b ^* of the wing portion 2W, for example, 1) the skin-facing surface of the purple region (the backsheet 4 which is the purple member) in the absorber non-arrangement region 5N Examples thereof include a method of increasing the number of other members (the number of stacked layers) arranged on the side as compared with that in the wing portion 2W, and 2) a method of providing a consolidation portion in the wing portion 2W.

In the napkin 1, as described above, as shown in FIGS. 2 and 3, the absorbent body 5 has the non-skin side concave portion 9 on the non-skin facing surface (the surface facing the back sheet 4), and the back sheet 4 ( The purple member) is not joined to the absorber 5 at the non-skin side recessed portion 9. With such a configuration, the light transmittance and the like are different between the arrangement area of the non-skin side concave portion 9 (the area overlapping the non-skin side concave portion 9 in plan view) and the non-arrangement area. As shown in (b), when viewed from the non-skin facing surface Sb side, the appearances are different in both areas. As a result, it is possible to give the viewer a deep stereoscopic effect, and as a result, the above-mentioned functional material ( It becomes easier to recall the effects of the cooling sensation agent and the antibacterial agent.

In the napkin 1, as shown in FIG. 1B, when the non-skin facing surface Sb is viewed, the color of the absorber 5 is visible through the purple region of the back sheet 4 (purple member). The color of the absorber 5 visually recognized over the region is different from the color of the absorber 5 visually recognized when the skin facing surface Sa of the napkin 1 is visually observed. The “color of the absorber 5” when the skin-facing surface Sa or the non-skin-facing surface Sb of the napkin 1 referred to here is the color of the area where the absorber 5 is arranged, that is, the color of the absorbent body 5 is absorbed by the napkin 1 in a plan view. It is synonymous with the color of the region overlapping with the body 5.
The difference in the color appearance of the absorber 5 is, for example, the color of the member arranged on the skin-facing surface side of the absorber 5 (when a plurality of the members are laminated, the color of the laminated body). Can be realized when different from the purple color of the purple region of the back sheet 4. In the illustrated form, since the main members arranged on the skin-facing surface side of the absorbent body 5 are the top sheet 3 and the second sheet 6, the color of the laminate of both sheets 3, 6 is different from the purple color of the back sheet 4. In this case, as described above, the appearance of the color of the absorber 5 may be different between the skin facing surface Sa side and the non-skin facing surface Sb side. The color of the top sheet 3 and the second sheet 6 is typically white or an achromatic color close to white.
Since the appearance of the color of the absorber 5 is different between the skin-facing surface Sa and the non-skin-facing surface Sb of the napkin 1 as described above, the impression received from the appearance of the napkin 1 is the skin-facing surface Sa and the non-skin facing surface Sb. This makes it possible to give the user a gorgeous impression and a devised impression on the napkin 1, and to alleviate the depressive feeling of the user before wearing. In addition, depending on the color of the absorber 5, a psychological effect given to the viewer by the skin-facing surface Sa and the non-skin-facing surface Sb of the napkin 1 by a combination (color overlap) with the purple color of the purple member (back sheet 4). Not only the effect but also the visual effect can be made different, and the usefulness of the napkin 1 can be further improved.

As described above, when the appearance of the color of the absorber 5 (the color of the arrangement region of the absorber 5) is different between the skin facing surface Sa and the non-skin facing surface Sb of the napkin 1, the skin facing surface Sa is visually recognized. The color of the absorber 5 (the arrangement region of the absorber 5) and the color of the absorber 5 (the arrangement region of the absorber 5) visually recognized on the non-skin facing surface Sb are of the same system. preferable. The difference between colors of the same system can give a small discomfort of "somehow different" without giving a strong sense of discomfort to the viewer, but generally, such a small discomfort is relatively strong impression. Remain in. Therefore, since the color of the absorber 5 on the skin facing surface Sa side of the napkin 1 and the color of the absorber 5 on the non-skin facing surface Sb side are different within the same system range, the skin facing surface Sa and the non-skin facing surface Sb are different. A slight discomfort occurs due to the comparison between and, whereby the distinction between the two surfaces Sa and Sb becomes clearer, and the mounting position of the napkin 1 can be correctly recognized. In the unused state of the napkin 1, since the non-skin facing surface Sb is the individual body 20 positioned outside the skin facing surface Sa, the user of the napkin 1 normally uses the non-skin facing surface Sb, Since the napkin 1 is visually observed in the order of the skin facing surface Sa, there is an opportunity to compare the both surfaces Sa and Sb in a series of mounting operations.

In the Munsell hue circle divided into 20 hues, the above-mentioned "same system color" refers to a hue range to which the color belongs, or a color belonging to two hue ranges located on both sides of the hue range. For example, since purple belongs to the hue ranges PB, P, and RP in the Munsell hue circle, the “colors of the same system as purple” include the hue ranges PB, P, and RP and the two hue ranges B located on both sides thereof. A color belonging to any of P is included. Further, since blue belongs to the hue range 10B in the Munsell hue circle, the “color of the same system as blue” includes a color belonging to the hue range 10B and two hue ranges 5B and 5PB located on both sides of the hue range 10B. included.

In addition, as described above, when the appearance of the color of the absorber 5 (the color of the arrangement region of the absorber 5) is different between the skin facing surface Sa and the non-skin facing surface Sb of the napkin 1, the skin facing surface Sa is visually checked. The color of the absorbent body 5 (the arrangement area of the absorbent body 5) visually recognized in (1) and the color of the absorber 5 (the arrangement area of the absorbent body 5) visually recognized on the non-skin facing surface Sb are of the same system. In addition to the above, the color of the absorber 5 (the arrangement region of the absorber 5) visually recognized on the skin facing surface Sa is the same as the color of the absorber 5 visually recognized on the non-skin facing surface Sb (of the absorber 5). It is preferable that the color is a lighter color that is less vivid than the color of the arrangement area), and specifically, the saturation C ^* is preferably low. This makes it possible to give the user a more secure feeling before using the napkin 1. The saturation C ^* is calculated by the following formula.
Chroma ^{C * = {(a *)} 2 + (b *) 2} 1/2

For example, in the case where the absorber 5 is a blue member that can be visually confirmed to be blue as a single body as described later, when the non-skin facing surface Sb of the napkin 1 is visually checked, it is visually recognized through the purple region of the backsheet 4 (purple member). Of the saturation C ^* between the blue color of the absorber 5 (blue member) and the blue color of the absorber 5 (blue member) visually recognized through the top sheet 3 and the second sheet 6 when the skin facing surface Sa is visually observed ^. When the latter is subtracted from the former, the difference is preferably 2 or more and 12 or less, more preferably 3 or more and 10 or less, assuming the former>the latter.

The color of the absorbent body 5 is not particularly limited, and may be white, which is a typical color of the constituent members of the sanitary napkin, or an achromatic color close to white, or a color other than such a typical color. Alternatively, the color may be purple, like the purple region of the back sheet 4.

The absorber 5 may be visible as a single violet chromatic color. In other words, when the absorber 5 is directly viewed without using other members, the visible color of the absorber 5 may be a non-purple chromatic color. Blue can be illustrated as a specific example of this non-purple chromatic color. The "blue" in the present invention is a color having a chromaticity b ^{* in} the range of 0 or less in the CIE1976 (L ^* a ^* b ^* ) color system.

Blue is a color that can remind the viewer of a refreshing refreshing feeling. The absorber 5 is a blue member that can be visually recognized as blue by itself, and the blue color is visible when the skin facing surface Sa and/or the non-skin facing surface Sb is visually checked before wearing the napkin 1. , A user who is about to wear the napkin 1 can be expected to obtain a refreshing feeling while wearing the napkin 1 without causing a feeling of dullness or jerkyness that an absorbent article of this type tends to hold. It is possible to expect further improvement in the feeling of use of the napkin 1. In particular, when the functional material contained in the napkin 1 has an effect that matches the psychological effect of blue color, specifically, for example, a cooling sensation agent that makes the wearer of the napkin 1 perceive a cold sensation. In some cases, it is effective that the absorber 5 is a blue member.

As a preferred embodiment of an absorbent article using an absorber that is a blue member, in the napkin 1 where the back sheet 4 is a purple member, the absorber 5 is a blue member that is visible in blue alone, and a functional material. Examples of the form include a cooling sensation agent.
In such a preferred embodiment, when the non-skin-facing surface Sb of the napkin 1 is viewed, the blue color of the absorber 5 that is visually recognized through the purple region of the backsheet 4 is when the skin-facing surface Sa of the napkin 1 is viewed. Compared with the blue color of the absorber 5 which is visible through the top sheet 3 and the second sheet 6 which is white or an achromatic color close to white, the shade becomes darker due to the overlapping with purple. In particular, when the chromaticity b ^* of purple of the back sheet 4 is larger than the chromaticity b ^* of blue of the absorber 5, the blue color of the absorber 5 is likely to appear dark. The dark blue color of the absorber 5 caused by the overlapping with the purple color is visible not only when the napkin 1 is mounted, but also when the napkin 1 is the individual body 20 through the transparent portion of the packaging material 15. Therefore, the psychological effect of blue color can be sufficiently given to the user before using the napkin 1, and the concealing property of absorbed menstrual blood can be improved. To explain the effect of improving the concealing property of the latter, when discarding the napkin 1 after use, normally, after discarding the napkin 1 after use with its non-skin facing surface Sb facing outward, it is discarded. The dark blue color of the absorbent body 5 visually recognized through the member (back sheet 4) has a color close to that of the menstrual blood absorbed and held by the absorbent body 5, and therefore the entire absorbent body 5 is visually observed on the non-skin facing surface Sb. However, when the napkin 1 is discarded, menstrual blood is less noticeable when the napkin 1 is discarded. On the other hand, when the skin facing surface Sa of the napkin 1 is visually inspected, the blue color of the absorber 5 visually recognized through a typical white member such as the topsheet 3 is over the purple region of the purple member (backsheet 4). Where the shade of the absorber 5 is lighter than the blue color of the absorber 5 that is visually recognized, the light blue of the absorber 5 can give a viewer a feeling of comfort and a sense of security.

The structure of the absorber 5 that is a blue member (a member that can be visually recognized as blue alone) is not particularly limited, and the point is that the color visually recognized when the absorber 5 is directly viewed without any other member is blue. If The absorber 5 which is a blue member is typically blue at least on the outer surface (skin-facing surface and non-skin-facing surface).
For example, when the absorbent body 5 is the sheet-type absorbent body 5A shown in FIG. 2, at least the main body absorbent sheet 51 forming the outer surface of the absorbent body 5A may be blue, and the central portion entirely covered by the sheet 51. The absorbent sheet 50 may be blue or non-blue. Further, when the absorbent body 5 is the laminated fiber type absorbent body 5B shown in FIG. 3, at least the core wrap sheet 53 forming the outer surface of the absorbent body 5B may be blue, and the entire sheet covered by the sheet 53 is absorbed. The sex core 52 may be blue or non-blue.
The blue member, like the purple member, is a white member or an achromatic member close to white (for example, the member forming the outer surface of the blue member such as the sheets 51 and 53) colored by a known dyeing method such as printing. It may be a thing and may be comprised from the blue primary dyed fiber.

The blue color of the absorber 5 (blue member) visible when observing the skin-facing surface Sa of the napkin 1, for example, the blue color visually recognized from the skin-facing surface Sa in the area where the absorber 5 is arranged, has a psychological effect. From the viewpoint of more surely playing, the chromaticity a ^* is preferably -10 or more and 0 or less, more preferably -9 or more and -2 or less, and the chromaticity b ^* is preferably -10. It is 0 or more, and more preferably -9 or more and -1 or less.
Purple in the purple region visible when the skin facing surface Sa of the napkin 1 is observed, for example, a region in which the purple region of the purple member (backsheet 4) is arranged without the blue member (absorber 5) being arranged (for example, The purple color visually recognized from the skin facing surface Sa of the wing portion 2W) has a chromaticity a ^* of preferably 0 or more and 2 or less, more preferably from the viewpoint of more reliably exerting the psychological effect brought by the purple. Is more than 0 and 1.5 or less, and the chromaticity b ^* is preferably -10 or more and 0 or less, more preferably -9 or more and -1 or less.

The difference in chromaticity a ^* between the blue color of the absorber 5 (blue member) and the purple color of the purple region, which is visible when the skin-facing surface Sa of the napkin 1 is observed, is preferably, when the latter is subtracted from the former. It is 3 or more and 20 or less, more preferably 5 or more and 15 or less.
The difference in chromaticity b ^* between the blue color of the absorber 5 (blue member) and the purple color of the purple region, which is visible when the skin facing surface Sa of the napkin 1 is observed, is preferably the same when the latter is subtracted from the former. It is −0.5 or more and −10 or less, more preferably −1 or more and −5 or less.
In the difference between the chromaticities a ^* and b ^* , the “absorber 5 (blue member)” is, for example, an arrangement region of the absorber 5 (blue member), and the “purple region” is, for example, The purple region of the purple member (back sheet 4) is arranged without the absorber 5 (blue member) being arranged, and is the wing portion 2W in the illustrated embodiment, for example.

From the viewpoint of more reliably exerting the psychological effect brought about by the purple color in the purple region of the purple member (back sheet 4) and further the psychological effect brought about by the color of the absorber 5, in particular, the skin-facing surface of the napkin 1. The total light transmittance of the back sheet 4 is preferably 20 from the viewpoint of more reliably causing a phenomenon in which the color (for example, blue) of the absorber 5 is different between Sa and the non-skin facing surface Sb. % Or more and 80% or less, more preferably 25% or more, and preferably 80% or less, more preferably 60% or less from the viewpoint of the effect of concealing excrement.

From the same viewpoint, the total light transmittance of the other constituent members of the napkin 1 is preferably set as follows.
The total light transmittance of the top sheet 3 is preferably 20% or more, more preferably 25% or more, and preferably 80% or less, more preferably 60% or less from the viewpoint of the effect of concealing excrement. The total light transmittance of the second sheet 6 may be in the same range as the top sheet 3.
The total light transmittance of the absorber 5 is preferably 0% or more and 20% or less, more preferably 5% or more and 15% or less.
The total light transmittance of the transparent portion of the packaging material 15 is preferably 30% or more, more preferably 40% or more, and a practical upper limit value is 90%.
The total light transmittance of each of the above-mentioned members is a value when a member (for example, a backsheet) to be measured is taken out from the absorbent article and measured by the above method.

As described above, the napkin 1 is, as shown in FIGS. 4 to 6, folded together with the packaging material 15 into an individual body 20 when unused or discarded, and is fixed to the outer surface of the individual body 20. Where the member 16 is disposed, the color of the fastening member 16 may be the same color as the purple color of the purple region (the backsheet 4 which is a purple member) or the non-purple color (for example, blue) of the absorber 5. preferable. The color of each of the fastening member 16, the purple region (backsheet 4), and the absorber 5 as used herein refers to the color visually recognized when the region or member is directly visually observed without any other member. The “color of the same system” is as described above. Since the color of the fastening member 16 is the same color as the purple region or the color of the absorber 5, the psychological effect brought about by the color of these regions or members can be more reliably exhibited. Further, when the color of the fastening member 16 is the same color as the purple region or the color of the absorber 5, the user who sees the fastening member 16 can check the napkin 1 included in the individual body 20. It is possible to infer that the constituent members may be colored in the same color as that of the fastening member 16, which can make the user feel happy before using the napkin 1.

Further, in addition to the color of the fastening member 16 being the same color as the purple of the purple region (the backsheet 4 which is a purple member) or the non-purple (for example, blue) of the absorber 5, as described above, It is preferable that the saturation C ^* is higher than that of purple or non-purple (for example, blue). As a result, the psychological effect of the color of the fastening member 16 described above is more reliably exhibited.

When the packaging material 15 has a high light-transmitting portion having relatively high light transmittance (total light transmittance) such as the transparent portion and a low light-transmitting portion having relatively low light transmittance, the fastening member. It is preferable that 16 is arranged in the low light transmitting portion. The high light-transmitting portion is a portion where the color of the napkin 1 packaged with the packaging material 15 is visually recognizable. When the fastening member 16 is arranged at such a portion where the napkin 1 is visible. This is because it hinders the visual recognition of the napkin 1.

From the above findings on the individual body 20, the following is given as a preferred embodiment of the napkin 1.
On the non-skin facing surface Sb of the napkin 1, the packaging material 15 for packaging the napkin 1 is arranged,
When the napkin 1 is folded on the packaging material 15 together with the packaging material 15 to form the individual packaging body 20, it is located on the outer surface of the individual packaging body 20 and the end of the packaging material 15 is stopped at a predetermined position of the packaging material 15. The fastening member 16 to be worn is arranged,
The packaging material 15 has a portion having a relatively high light transmittance and a portion having a relatively low light transmittance, and the fastening member 16 is arranged on the low light transmitting portion,
The color of the fastening member 16 is the same color as the color of the purple region (the back sheet 4 which is a purple member) or the absorber 5,
When the individual packaging body 20 is viewed, the color of the purple region (the backsheet 4 which is a purple member) or the absorber 5 is visible through the high light-transmitting portion.
