The napkin 1 has a skin-facing surface Sa that can come into contact with the wearer's skin and a non-skin-facing surface Sb located on the opposite side of the skin-facing surface Sa, and an absorbent body 5 that can absorb body fluids. and a back sheet 4 forming the non-skin facing surface Sb.
Both the skin-facing surface Sa and the non-skin-facing surface Sb of the napkin 1 are the outermost surfaces of the napkin 1 . When the napkin 1 is worn, the skin-facing surface Sa can come into contact with the wearer's skin, and the non-skin-facing surface Sb is positioned opposite to the skin-facing surface Sa.
The napkin 1 may comprise a sheet-type absorbent body 5A shown in FIG. 2 as the absorbent body 5, or may comprise a pile-type absorbent body 5B shown in FIG. The description of the absorber 5 below applies to both the absorbers 5A and 5B unless otherwise specified.

More specifically, the napkin 1 has a longitudinal direction X corresponding to the front-rear direction of the wearer, that is, a direction extending from the abdomen to the back through the crotch, and a lateral direction Y orthogonal to the longitudinal direction X. , an absorbent body 5, a back sheet 4 arranged on the non-skin facing side of the absorbent body 5, and a skin facing surface Sa of the napkin 1 arranged closer to the wearer's skin than the absorbent body 5 a forming topsheet 3; The top sheet 3 is a member that can come into contact with the wearer's skin when the napkin 1 is worn, and is typically liquid permeable. On the other hand, the backsheet 4 is typically liquid-impermeable, hardly-permeable, or water-repellent (in short, leak-proof).

As used herein, the term “skin-facing surface” refers to the surface of the absorbent article or its constituent members (for example, the absorbent body 5) facing the wearer's skin when the absorbent article is worn, that is, the surface facing the wearer's skin. The "non-skin facing side" is the side of the absorbent article or its constituent members opposite to the skin side when the absorbent article is worn, that is, the side relatively far from the wearer's skin. It is an aspect that can be It should be noted that the term "when worn" as used herein means a state in which the absorbent article is maintained in a normal and appropriate wearing position, that is, in a correct wearing position of the absorbent article.

The napkin 1 is arranged in the wearer's crotch region and includes a longitudinal central region M including an excretory part facing part (not shown) facing the wearer's excretory part such as the vaginal opening, and the longitudinal central region M. It is divided into three areas: a front area F arranged on the front side (abdominal side) of the wearer and a rear area R arranged on the rear side (dorsal side) of the wearer from the longitudinal center area M.

The napkin 1 has a pair of wing portions 2W, 2W on both sides in the horizontal direction Y with the absorbent body 5 interposed therebetween. The wing portion 2W includes a back seat 4. As shown in FIG. 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 along the longitudinal direction X of the absorbent body 5, and a longitudinal central region M , the side flap portions 2S extend outward in the lateral direction Y from the peripheral portion, and a pair of wing portions 2W, 2W are provided on both left and right sides along the longitudinal direction X of the absorbent main body portion 2 in the longitudinal central region M. deferred. The wing portion 2W is provided with a wing adhesive portion (not shown) as fixing means for fixing the wing portion 2W to clothing such as shorts on its non-skin facing surface. In addition, since the wing part 2W is folded back to the non-skin facing surface (outer surface) side of the crotch part of clothing such as shorts, the non-skin facing surface of the wing part 2W, which is the surface on which the wing adhesive part is formed, is , when in use, is oriented toward the wearer's skin and forms a skin-facing surface (see FIG. 6). In addition, the napkin 1 is attached to 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 extending in the longitudinal direction X sandwiched between the side flap portions 2S, 2S, such as shorts. A main body adhesive portion 10 is provided as fixing means for fixing to clothing. The wing adhesive portion and the main adhesive portion 10 are each covered with a release sheet (not shown) made of film, nonwoven fabric, paper, or the like before use.

In the present invention, the longitudinal central region of an absorbent article having no wing portions (for example, a typical disposable diaper) corresponds to the region located in the middle when the absorbent article is vertically divided into three equal parts. .

In the napkin 1, a second sheet 6 is arranged between the top sheet 3 and the absorbent body 5. - 特許庁The second sheet 6 is a separate sheet from the top sheet 3 and the absorbent body 5, and is also called a sublayer sheet in the technical field. is joined to

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

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

As the above-described members constituting the napkin 1, those commonly used in absorbent articles of this type can be used without particular limitation, on the premise that the members are in accordance with the description of the members below. . As the top sheet 3, for example, a known liquid-permeable single-layer or multi-layer nonwoven fabric can be used. As the back sheet 4, a sheet having a leakproof property, that is, a liquid-impermeable (a property that does not allow liquid to pass through at all) or a liquid-impermeable (a property that makes it difficult for liquid to pass through, although it cannot be said to be liquid-impermeable) is used. It is possible to use a sheet having a moisture-permeable resin film, for example. 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 nonwoven fabric can be used.

As shown in FIG. 1(a), the napkin 1 includes an absorbent body 5 and members (in the illustrated form, the top sheet 3 and the second sheet 6) arranged on the skin facing side of the absorbent body 5. The non-skin-facing surface side (the back sheet 4 side) of 5 has a skin-side recessed portion 8 that is recessed integrally. The skin-side recessed portion 8 does not penetrate the absorbent body 5 in the thickness direction, and has an opening on the skin-facing surface of the top sheet 3 and 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 bodily fluids such as menstrual blood in the planar direction. In the illustrated embodiment, the skin-side recessed portion 8 has a linear shape extending in one direction in plan view, and the skin-side recessed portion 8 as a whole has a closed annular shape in plan view. The skin-side recessed portion 8 is formed at least in the longitudinal central region M. As shown in FIG.

In the napkin 1, as shown in FIG. 1(b), 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. As shown in FIG. 2, the back sheet 4 is not joined to the absorbent body 5 at the non-skin side recessed portion 9, and is joined to the absorbent body 5 at portions other than the non-skin side recessed portion 9 via an adhesive 11. It is 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 on the opposite side of 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 plan view. In the illustrated embodiment, the non-skin-side recessed portion 9 has the same plan view shape as the skin-side recessed portion 8 .

Both of the recessed portions 8 and 9 are formed by a known pressing process, and can be called "pressed portions" from the method of forming. The depressed portions 8 and 9, which are compressed portions, have a higher density than the surrounding non-compressed portions. In the absorber 5, a high-density portion, which is a portion that overlaps with the recessed portion 98 in plan view, and a low-density portion where the recessed portions 8 and 9 are not formed coexist. A difference in density is generated in the surface direction between the facing surface and the non-skin facing surface.

The absorber 5 will be explained. The absorbent body 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 to the rear region R via the longitudinal central region M. As shown in FIG.

FIG. 2 shows an absorbent body 5A that can be used as the absorbent body 5. As shown in FIG. The absorber 5A is an absorber mainly composed of an absorbent sheet, which is a sheet-like absorber, and is thinner and more flexible than the fiber stack type absorber 5B described later. The absorbent sheet typically comprises a fibrous sheet mainly made of a fibrous material such as wood pulp, and a water-absorbing material such as a water-absorbing polymer fixed inside or on the surface of the fibrous sheet. ing. The absorbent sheet may have a structure in which water absorbent polymer particles 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 absorber 5A includes a central absorbent sheet 50 arranged in the center of the napkin 1 in the lateral direction Y, and the entire sheet 50 is covered to form the outer surface (skin-facing surface, non-skin-facing surface) of the absorber 5A. and a main body absorbent sheet 51. Both sheets 50 and 51 are the absorbent sheets.
In the illustrated embodiment, both sheets 50 and 51 have a laminated structure in which one sheet is folded. The laminated structure of the central absorbent sheet 50 is shorter in both the vertical direction X and the horizontal direction Y than the laminated structure of the main absorbent sheet 51, and the inside of the laminated structure of the main absorbent sheet 51 is specifically is placed between the two sheets 51, 51 folded over. 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 longitudinal central region M facing the excretory part. The portion where the central absorbent sheet 50 is arranged (overlapping portion of both sheets 50 and 51) is a thick portion that is thicker than the peripheral portion and protrudes toward the skin of the wearer of the napkin 1. As shown in FIG.

FIG. 3 shows an absorbent body 5B that can be used as the absorbent body 5. As shown in FIG. The absorbent body 5B is made by stacking fibrous materials such as wood pulp, and covers an absorbent core 52 that forms 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 with an adhesive such as a hot-melt adhesive. The absorbent core 52 may contain a water-absorbing polymer in addition to the fibrous material. For example, the absorbent core 52 may have a configuration in which particles of the water-absorbing polymer are carried inside an aggregate of fibrous materials. As the core wrap sheet 53, a liquid-permeable sheet can be used, typically 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 to form an individual package 20, as shown in FIG. FIG. 5 shows a state in which the individual package 20 is partially unfolded, and FIG. 6 shows a state in which the individual package 20 is completely unfolded.
A packaging material 15 for packaging the napkin 1 is arranged on the non-skin facing surface Sb of the napkin 1, more specifically, on the non-skin facing surface of the backsheet 4 forming the non-skin facing surface Sb. The packaging material 15 is detachably fixed to the back sheet 4 via the body adhesive portion 10 (see FIG. 1(b)). As shown in FIG. 6, the individual package 20 includes the absorbent main body 2 with the pair of wing portions 2W, 2W folded toward the top sheet 3, along with the packaging material 15 along two folding lines L1, L1 and L1. It is formed by folding in the longitudinal direction X with the top sheet 3 facing inward at L2. At both side edges 20S, 20S along the longitudinal direction X of the individual package 20, the two folded packaging materials 15, 15 forming the side edges 20S are joined by heat sealing or the like.

The packaging material 15 has a transparent portion. The "transparent portion" as used herein refers to 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 packaging material 15 may be entirely transparent or partially transparent. The packaging material 15 forms the outer surface of the individual package 20, and when the individual package 20 is viewed from the outside, the color of the napkin 1 contained in the individual package 20 can be seen through the transparent portion of the packaging material 15. can be visually recognized.

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 hazemeter (for example, "Hazemeterndh 5000" manufactured by Nippon Denshoku Industries Co., Ltd.).

In the packaging material 15, when the napkin 1 is folded together with the packaging material 15 to form an individual package 20, it is positioned on the outer surface of the individual package 20 so that the end of the packaging material 15 is positioned at a predetermined position of the packaging material 15. A fastening member 16 is arranged to be fastened to. The fastening member 16 is fixed to one end of the packaging material 15 in the longitudinal direction X, as shown in FIG. The fastening member 16 has a rectangular shape in plan view, and its longitudinal direction is aligned with the vertical direction X. As shown in FIG. One end portion 16a in the longitudinal direction of the fastening member 16 is a fixed end portion fixed to the packaging material 15, and the other end portion 16b is a free end portion that is not fixed to other members. An adhesive (not shown) is applied to the surface of the individual package 20 facing the packaging material 15 (the surface opposite to the exposed surface of the individual package 20) of the free end 16b of the fastening member 16. The free end portion 16b is detachably attached to the packaging material 15 via the adhesive. The fastening member 16 functions as a sealing portion for the individual package 20 in an unused state, and also as an unsealing knob that is gripped with fingers when the individual package 20 is unsealed.

The napkin 1 includes a first colored member and a second colored member arranged closer to the wearer's skin than the first colored member and having a color different from the color of the first colored member, In addition, there is a color overlapping region 17 where at least a part of both colored members overlap each other in the thickness direction.
Here, the "color of the first colored member" and the "color of the second colored member" respectively refer to colors that are visually recognized when the colored member is viewed directly without passing through other members, and specifically For example, it refers to the color visually recognized when the colored member is taken out from the absorbent article and visually observed.
The color overlap region 17 is typically a region where the first colored member and the second colored member are overlapped in the thickness direction without any other colored member interposed therebetween.
The color of the napkin 1 that is visible from the non-skin-facing surface Sb of the napkin 1 in the color overlapping region 17 is different from the color that is visible from the skin-facing surface Sa of the napkin 1 in the color overlapping region. It is characterized in that it is also different from the color of the colored member.

The first colored member is typically visible at least from the non-skin facing surface Sb of the napkin 1 . In the illustrated embodiment, the backsheet 4 forming the non-skin facing surface Sb of the napkin 1 is the first colored member, and the absorbent body 5 is the second colored member. In the illustrated embodiment, the backsheet 4 has a larger area than the absorbent body 5 , covers the entire non-skin facing surface of the absorbent body 5 , and further extends outward from the periphery of the absorbent body 5 . Therefore, in the illustrated embodiment, the color-overlapping region 17 coincides with the arrangement region of the absorber 5 (second colored member), and the outline of the color-overlapping region 17 in plan view corresponds to matches the contour in .
In the illustrated embodiment, the absorber 5 (second colored member) overlaps the back sheet 4 (first colored member) in the thickness direction, that is, in the color overlapping region 17, depending on the color of the napkin 1. The color of the color overlap region 17 visible from Sb through the backsheet 4 and visible from the non-skin facing surface Sb (the color of the area where the absorbent 5 is arranged visible through the backsheet 4) It is different from the color of the color overlap region 17 viewed from the surface Sa (the color of the region where the absorber 5 is disposed viewed from the skin-facing surface Sa of the napkin 1). The term "arrangement area of the absorbent body 5" as used herein refers to a region of the napkin 1 overlapping with the absorbent body 5 (absorbent main body 2) in plan view. Therefore, in the illustrated embodiment, the overall shape of the absorbent body 5 (absorbent body 2) can be seen from both the skin-facing surface Sa and the non-skin-facing surface Sb of the napkin 1, but the visible color (the color of the color overlap region 17 ) differ between the skin-facing surface Sa and the non-skin-facing surface Sb.

As described above, the fact that the appearance of the color of the color overlap region 17 (the region where the absorber 5 is arranged) differs between the skin-facing surface Sa and the non-skin-facing surface Sb of the napkin 1 typically means that the absorber 5 The color of the member arranged on the skin-facing surface side of the absorber 5 (the color of the laminate when the members are laminated in multiple layers) and the member arranged on the non-skin-facing surface side of the absorbent body 5 Occurs in different cases. In this regard, in the illustrated embodiment, the members arranged on the side of the skin-facing surface of the absorbent body 5 are the top sheet 3 and the second sheet 6 that are different in color from the back sheet 4, so the skin-facing surface Sa of the napkin 1 and The color appearance of the absorber 5 differs from that of the non-skin facing surface Sb. The colors of the top sheet 3 and the second sheet 6 are typically white or an achromatic color close to white.

Since the appearance of the color of the color overlapping region 17 (arrangement region of the second colored member) is different between the skin-facing surface Sa and the non-skin-facing surface Sb of the napkin 1, the impression received from the appearance of the napkin 1 is different from that of the skin-facing surface Sa. The non-skin-facing surface Sb is different from the non-skin-facing surface Sb, thereby giving the user a gorgeous impression or an ingenious impression of the napkin 1, thereby alleviating the melancholy feeling of the user before wearing. In addition, depending on the colors of the first colored member (back sheet 4) and the second colored member, the combination of the colors of both members (overlapping of colors) allows the skin-facing surface Sa and the non-skin-facing surface Sb of the napkin 1 to , not only the psychological effect given to the viewer but also the visual effect can be varied, and the usefulness of the napkin 1 can be further improved.

To further explain the effect of the napkin 1, in the napkin 1, the first colored member and the second colored member are arranged so as to be visible. Since at least a part of both colored members can be visually recognized from the outside, the user of the napkin 1 can be given a psychological effect brought about by these colored members even before wearing the napkin 1.例文帳に追加. The user of the napkin 1 wears the napkin 1 because such a psychological effect relaxes the user, relieves the depressed mood during menstruation, etc., and wears the napkin 1 in a state where expectations for a good feeling of use are heightened. You can have a positive feeling, such as a sense of trust and a sense of security, about the specific effects that are actually played inside, and as a result, it is easy to realize the specific effects. In general, what is imaged in the brain can affect human senses, and the napkin 1 takes advantage of this to change the first colored member and the second colored member before the napkin 1 is put on. By making the napkin 1 feel good in use due to the psychological effects of the members, it is easier for the wearer to perceive specific actions and effects during wearing. As described above, the packaging material 15 forming the outer surface of the individual package 20 has a transparent portion, and when the individual package 20 is visually observed, the color of the napkin 1 can be visually recognized through the transparent portion. The first colored member (backsheet 4) and the second colored member (absorbent body 5) can be visually recognized through the transparent portion. Therefore, the colors of both the colored members can be visually recognized not only when the napkin 1 is put on, but also when the individual package 20 is carried, and the psychological effect brought about by the colors of the both colored members is further ensured. can be played.

The first colored member (backsheet 4) and the second colored member (absorbent body 5) are each a white or nearly white achromatic member colored to a desired color by a known dyeing method such as printing. It may be composed of dope-dyed fibers of a desired color. A dope-dyed fiber is a fiber that has been colored in the fiber manufacturing stage, and is manufactured through a coloring process in which, for example, a colorant such as a pigment is added to a manufacturing intermediate in the stages from resin manufacturing to fiberization.

Incidentally, the color of the constituent members of this type of absorbent article is usually white or an achromatic color close to white. The color of other constituent members of is white or achromatic color close to white.
In the present specification, the white or near-white achromatic member has a lightness L ^* of preferably 90 or more, more preferably 92 or more, and the chromaticity a ^* and chromaticity b ^* are the purple member described later. (Backsheet 4) has a smaller chromaticity a ^* , a larger chromaticity b ^* than the purple member, or a smaller chromaticity a* and a larger chromaticity ^{b* than} the purple member Large is preferred.
The chromaticity a ^* of the white or achromatic color close to white member is preferably -1 or more and 1 or less, preferably -0.5 or more and 0.5 or less, more preferably the lower limit 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.

The color visible from the non-skin facing surface Sb of the napkin 1 in the color overlapping region 17 is preferably the same color as the color visible from the skin facing surface Sa of the napkin 1 in the color overlapping region 17 . The difference between the colors of the same system makes the viewer recognize the difference, but it does not give a strong sense of discomfort, and it can give a small sense of discomfort that "it is somehow different". remain in Therefore, the color of the color overlapping region 17 on the side of the skin facing surface Sa of the napkin 1 and the color of the color overlapping region 17 on the side of the non-skin facing surface Sb are different within the same range, so that the skin facing surface Sa and the non-skin facing surface Sa A slight sense of incongruity is caused by comparing the surface Sb with the surface Sb, so that the distinction between the surfaces Sa and Sb becomes clearer, and the mounting position of the napkin 1 can be correctly recognized. When the napkin 1 is not in use, the non-skin facing surface Sb is positioned outside the skin facing surface Sa. The napkin 1 is viewed in the order of the skin facing surface Sa, and there is an opportunity to compare both surfaces Sa and Sb in a series of wearing operations.

The above-mentioned "colors of the same family" refer to colors belonging to the hue range to which the color belongs or two hue ranges located on both sides of the hue range in the Munsell hue circle divided into 20 hues. For example, since purple belongs to the hue ranges PB, P, and RP on the Munsell color wheel, the "colors of the same family as purple" include the hue ranges PB, P, and RP, and the two hue ranges B and B located on both sides thereof. Colors belonging to any of P are included. Further, since blue belongs to the hue range 10B on the Munsell color wheel, the "colors of the same family as blue" include colors belonging to the hue range 10B and the two hue ranges 5B and 5PB located on both sides thereof. included.

The color viewed from the skin-facing surface Sa of the napkin 1 in the color overlapping region 17 has a lower saturation C ^* than the color viewed from the non-skin facing surface Sb of the napkin 1 in the color overlapping region 17. preferable. That is, the color of the visually recognized color overlapping region 17 (arrangement region of the absorber 5) on the skin-facing surface Sa is the color of the visually recognized color overlapping region 17 (arrangement region of the absorber 5) of the non-skin facing surface Sb. ), it is preferably a pale color that is inferior in vividness. In particular, as described above, when the color viewed from the skin-facing surface Sa of the napkin 1 in the color overlapping region 17 and the color viewed from the non-skin-facing surface Sb are of the same color, the above-mentioned More preferably, there is a magnitude relationship between the chroma C ^* . By establishing the magnitude relationship of the chroma C ^* , it becomes possible to give the user a sense of security before using the napkin 1 more reliably. Saturation C ^* is calculated by the following equation.
Saturation C ^* ={(a ^* ) ²⁺ (b ^* ) ² } ^1/2

The chromaticity a ^* and chromaticity b ^* are indicators of the hue and chroma of the color (for example, purple), respectively.
In the present invention, chromaticity a ^* , chromaticity b*, chroma C ^* , and lightness ^{L* ,} which will be described later, are based on the L ^* a ^* b ^* table standardized by the Commission Internationale de l'Eclairage (CIE) in 1976. It is based on the color system (CIE1976 (L ^* a ^* b ^* ) color system).
Chromaticity a ^* , chromaticity b ^* , and lightness L ^* are each measured according to JIS Z 8781 using a commercially available color difference meter (for example, a handy spectral color difference meter NF333 (trade name) manufactured by Nippon Denshoku Industries Co., Ltd.). -4 can be measured.

For example, when the second colored member (absorbent body 5) is a blue member that can be visually recognized in blue by itself as described later, the color that is visually recognized from the non-skin facing surface Sb of the napkin 1 in the color overlap region 17, i.e. The color of the arrangement area of the absorbent body 5 (blue member) that is visible through the first colored member (back sheet 4) and the color that is visible from the skin-facing surface Sa of the napkin 1 in the color overlapping area 17, that is, the top sheet 3 and the difference in saturation C ^* between the color of the area where the absorber 5 (blue member) is arranged and viewed through the second sheet 6 is preferably 2 12 or less, more preferably 3 or more and 10 or less.

In the present invention, the colors of the first colored member and the second colored member are not particularly limited, and an arbitrary color can be selected on the premise that they are different colors from each other and are not white or an achromatic color close to white. obtain. The first colored member and the second colored member are typically one specific chromatic color as a whole, but on the premise that the one specific chromatic color is visible from the outside, the Only part of the member may have a specific chromatic color, and the other part may be white or achromatic near white.

In the napkin 1, the back sheet 4 (first colored member) is visible when the non-skin facing surface Sb of the napkin 1 is viewed, and when the skin facing surface Sa of the napkin 1 is viewed, at least the skin It is visible in the non-arrangement area|region (area|region which does not overlap with the absorber 5 by planar view) in the opposing surface Sa. On the side of the back sheet 4 facing the skin, other members including the absorber 5 (second colored member) are laminated so as to cover the back sheet 4, so depending on the arrangement of the other members , the color (for example, purple) of the back sheet 4 may not be visually recognized when the skin-facing surface Sa of the napkin 1 is viewed. In particular, since the absorber 5 is relatively thick and poor in light transmittance, the color of the backsheet 4 may not be visually recognized when the skin-facing surface Sa of the napkin 1 is visually observed in the area where the absorber 5 is arranged. However, in the non-arranged region of the absorber 5, a relatively thin sheet such as a non-woven fabric with high light transmittance (for example, the top sheet 3, the side sheet 7, and the second sheet 6) is usually stacked one or several sheets. Therefore, the color of the backsheet 4 can be sufficiently recognized when viewing the skin-facing surface Sa of the napkin 1 .

The non-arranged region of the absorbent body 5 (second colored member) in the napkin 1, that is, the portion where the color of the back sheet 4 (first colored member) can be visually recognized when viewing the skin-facing surface Sa of the napkin 1, is the wing portion 2W. The side flap part 2S containing can be illustrated. In particular, as shown in FIGS. 2 and 3, the wing portion 2W has only one side sheet 7 made of non-woven fabric or the like disposed on the skin-facing surface of the back sheet 4. The color (for example, purple) of the back sheet 4 can be sufficiently visually recognized by visual inspection.

In the napkin 1, as shown in FIG. 1, the non-absorbent body region 5N extends in the longitudinal direction X between the wing part 2W and the absorbent body 5, and the skin facing surface Sa of the napkin 1 is visually observed. When this is done, the color of the first colored member (back sheet 4) is visible in the wing portions 2W and the absorber non-arranged regions 5N, and the absorber non-arranged regions 5N are more visible than the wing portions 2W. The visually recognized color has a small chromaticity a ^* and a large chromaticity b ^* . When wearing the napkin 1 on clothes such as shorts, the wing portion 2W is usually folded toward the non-skin facing surface Sb in the non-absorber non-arranged region 5N while visually checking the skin facing surface Sa of the napkin 1. However, with the above configuration, the positions of the absorbent body non-arranged regions 5N to be folded are clarified, so that the operation of folding the wing portions 2W is facilitated, and the operability of the napkin 1 is improved. obtain.

As described above, when observing the skin-facing surface Sa of the napkin 1, "the chromaticity a ^* of the non-absorbent region 5N < the chromaticity a ^* of the wing portion 2W" and the "color of the non-absorbent region 5N Degree b ^* >chromaticity b ^* of wing portion 2W” can be achieved by: Examples include a method of increasing the number of other members arranged (the number of layers) as compared with that in the wing portion 2W, and 2) a method of providing a consolidation portion in the wing portion 2W.

As a preferred embodiment of the absorbent article of the present invention, the first colored member (backsheet 4) is a purple member that can be visually recognized as purple by itself, and the second colored member (absorbent body 5) is visually recognized as blue by itself. A possible blue member can be exemplified.
Here, the phrase “visually recognizable as purple by itself” means that the color of the member (the first colored member) that is visually recognized is purple when the member (the first colored member) is directly viewed without passing through other members. In addition, the term “visible blue by itself” means that the color that is visually recognized when the member (the second colored member) is directly viewed without passing through other members is blue.

"Purple" as used in the present invention is a color having chromaticity a ^* in the range of 0 or more and chromaticity b ^* in the range of 0 or less in the CIE1976 (L ^* a ^* b ^* ) color system.
Purple is said to have the effect of healing the sadness and anger in the heart, and is used in relaxing spaces as a healing color that balances the mind and body. Purple also symbolizes spirituality and is a color favored by artists, therapists, healers, etc., as it has the effect of enhancing inspiration and broadening sensibility. In addition, cold colors (e.g., blue) make the viewer feel cold and warm colors (e.g., red) make the viewer feel warm, while purple is a neutral color, so it makes the viewer feel cold and warm. It is difficult to conjure up such an extreme image. The purple first colored member (back sheet 4) that brings about such a psychological effect is arranged so as to be visible to the user (wearer) in the napkin 1, giving the user a purple psychological effect, Before using the napkin 1 (for example, during the operation of wearing the napkin 1) and during use, the user's depressed mood can be relieved.
In addition, the back sheet 4 (first colored member) is arranged close to the packaging material 15 forming the outer surface of the individual package 20 when the napkin 1 is in the individual package 20 shown in FIG. It is a member that can be easily seen from the outside. When such a back sheet 4 is purple, a series of mounting operations before use of the napkin 1, that is, "open the individual package 20, go through the partially unfolded state shown in FIG. Then, the user can certainly visually recognize and be aware of the purple color in the series of wearing operations of attaching the napkin 1 to the crotch region, so that the psychological effects of the purple color can be more reliably achieved.
In addition, when discarding the used napkin 1, the used napkin 1 is normally folded with the non-skin facing surface Sb facing outward, and then discarded. Since the purple color of 4 (first colored member) is close in color to the menstrual blood absorbed and retained in the absorbent body 5, the effect of making the menstrual blood less noticeable when the napkin 1 is discarded is exhibited.

"Blue" as used 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 make a viewer feel refreshed and cool. The second colored member (absorbent body 5) is a blue member that can be visually recognized in blue by itself, and the blue color is visible when the skin-facing surface Sa and the non-skin-facing surface Sb are visually observed before wearing the napkin 1. Therefore, the user who is going to wear the napkin 1 from now does not feel stuffy or damp, which is apt to be felt by this type of absorbent article, and can obtain a refreshing feeling while wearing the napkin 1. It can be expected that the feeling of use of the napkin 1 will be further improved.
Further, for example, when the napkin 1 contains a functional material that produces an action and effect that matches the psychological effect of blue, such as a cooling agent described later, the second colored member is a blue member, and the cooling agent The effect of blue is combined with the psychological effect brought about by blue, and further improvement in usability of the napkin 1 can be expected.

Further, by combining the first colored member (back sheet 4), which is a purple member, and the second colored member (absorbent body 5), which is a blue member, a synergistic effect can be expected.
For example, the blue visible from the non-skin facing surface Sb of the napkin 1 in the color overlap region 17 (that is, the arrangement area of the absorber 5 visible through the purple backsheet 4 when viewing the non-skin facing surface Sb Blue) is blue visible from the skin-facing surface Sa of the napkin 1 in the color overlap region 17 (that is, the top sheet 3 and the second sheet 6, which are white or achromatic colors close to white when the skin-facing surface Sa is viewed. In comparison with the blue color of the region where the absorber 5 is arranged, which is visually recognized in the figure, the color tone becomes darker due to the overlap with the purple color. The dark blue color of the absorbent body 5 caused by overlapping with the purple color can be visually recognized through the transparent portion of the packaging material 15 not only when the napkin 1 is put on, but also when the napkin 1 is packaged as an individual package 20. Therefore, before using the napkin 1, it is possible to sufficiently give the user a psychological effect brought about by the blue color, and to improve the concealability of absorbed menstrual blood and the like.
In addition, when viewing the skin-facing surface Sa of the napkin 1, the blue color of the arrangement area of the absorbent body 5 that is visible through a typical white member such as the top sheet 3 (from the skin-facing surface Sa of the color overlapping area 17 The visible blue) is compared with the blue of the arrangement area of the absorbent body 5 that is visible through the purple backsheet 4 (the blue that is visible from the non-skin facing surface Sb of the color overlapping area 17). Although it is thin, the light blue color of the absorber 5 can give a viewer a gentle feeling and a sense of security.

The structure of the absorber 5, which is a blue member, is not particularly limited as long as the color visually recognized when the absorber 5 is directly viewed without passing through other members is blue. Typically, at least the outer surface (the skin-facing surface and the non-skin-facing surface) of the absorber 5, which is a blue member, is blue.
For example, when the absorbent body 5 is the sheet-type absorbent body 5A shown in FIG. Absorbent sheet 50 may be blue or non-blue. Further, when the absorbent body 5 is the fiber-stacked type absorbent body 5B shown in FIG. The sex core 52 may be blue or non-blue.

Color of each part of the napkin 1 when the first colored member (backsheet 4) is a purple member that can be seen in purple by itself, and the second colored member (absorbent body 5) is a blue member that can be seen in blue by itself is preferably a color whose chromaticity a ^* and chromaticity b ^* are within the following ranges, respectively, from the viewpoint of further ensuring the psychological effects of blue or purple.
The color viewed from the skin-facing surface Sa of the napkin 1 in the color overlap region 17 has a chromaticity a ^* of preferably −10 or more and 0 or less, more preferably −9 or more and −2 or less, and chromaticity b ^* is preferably -10 or more and 0 or less, more preferably -9 or more and -1 or less.
The color viewed from the non-skin-facing surface Sb of the napkin 1 in the color overlap region 17 has a chromaticity a ^* of preferably −8 or more and 4 or less, more preferably −6 or more and 2 or less, and chromaticity b ^* is preferably -18 or more and -8 or less, more preferably -16 or more and -9 or less.
Other areas other than the color overlapping area 17, specifically, for example, the area where the first colored member is arranged without the second colored member (for example, the wing portion 2W), from the skin facing surface Sa of the napkin 1 The visible color has a chromaticity a ^* of preferably 0 or more and 2 or less, more preferably 0 or more and 1.5 or less, and a chromaticity b ^* of preferably −10 or more and 0 or less, more preferably -9 or more and -1 or less.
When the skin-facing surface Sa of the napkin 1 is observed, the color of the color overlapping region 17 and other regions other than the color overlapping region 17, specifically, for example, the first colored member without the second colored member arranged Regarding the color difference from the color of the region where the member is arranged (for example, the wing portion 2W), when the former is subtracted from the latter, the difference in chromaticity a ^* is preferably 3 or more and 20 or less, more preferably 5 or more and 15 or less. and the difference in chromaticity b ^* is preferably −0.5 or more and −10 or less, more preferably −1 or more and −5 or less.

From the viewpoint of more reliably exerting the psychological effects brought about by the colors of the first colored member (the back sheet 4 in the illustrated form) and the second colored member (the absorbent body 5 in the illustrated form), especially the napkin 1 The total light transmittance of the back sheet 4 from the viewpoint of ensuring that the appearance of the color (for example, blue) of the second colored member is different between the skin-facing surface Sa and the non-skin-facing surface Sb of the back sheet 4 is preferably 20% or more, more preferably 25% or more, and is preferably 80% or less, more preferably 60% or less from the viewpoint of the excreta-masking effect.

From the same point of view, it is preferable to set the total light transmittance of other constituent members of the napkin 1 as follows.
The total light transmittance of the top sheet 3 is preferably 20% or more, more preferably 25% or more, and is preferably 80% or less, more preferably 60% or less from the viewpoint of the excretion hiding effect. The total light transmittance of the second sheet 6 may be in the same range as that of the top sheet 3 .
The total light transmittance of the absorber 5 is preferably 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 the realistic upper limit is 90%.
The total light transmittance of each member is a value obtained by taking out the member to be measured (for example, the back sheet) from the absorbent article and measuring it by the method described above.

In the napkin 1, as shown in FIGS. 2 and 3 as described above, the absorbent body 5 has a non-skin side recessed portion 9 on its non-skin facing surface (surface facing the back sheet 4), and the back sheet 4 ( The first colored member) is not joined to the absorbent body 5 at the non-skin side recessed portion 9 . With such a configuration, the area where the non-skin side recessed portion 9 is arranged (the area overlapping the non-skin side recessed portion 9 in a plan view) and the non-arranged region have different light transmittance, etc. Therefore, the napkin 1 is shown in FIG. As shown in (b), when viewed from the side of the non-skin facing surface Sb, the two regions look different. It becomes easy to give a gorgeous impression and an ingenious impression to the napkin 1. In addition, when the napkin 1 contains a functional material, which will be described later, the user of the napkin 1 is easily reminded of the effects of the functional material.

As shown in FIGS. 4 to 6, the napkin 1 is folded together with the packaging material 15 to form an individual package 20 when not in use or discarded, and is attached to the outer surface of the individual package 20. Where the member 16 is arranged, the color of the fastening member 16 is the same as the color (eg, purple) of the first colored member (back sheet 4) or the color (eg, blue) of the second colored member (absorbent body 5). It is preferably a color of the family. The color of each of the fastening member 16, the first colored member, and the second colored member referred to here refers to the color visually recognized when the member is directly viewed without passing through other members. Also, the “color of the same family” is as described above. By setting the color of the fastening member 16 to be the same color as the color of the first colored member or the second colored member, the psychological effect caused by the color of the colored member can be exhibited more reliably. Further, when the color of the fastening member 16 is the same as the color of the first colored member or the second colored member, the user who sees the fastening member 16 will understand that the fixing member 16 is included in the individual package 20. It is possible to speculate that the constituent members of the napkin 1 may also be colored in the same color as the fastening member 16, which makes the user feel happy before using the napkin 1.例文帳に追加

In addition to the color of the fastening member 16 being the same as the color of the first colored member (back sheet 4) or the color of the second colored member (absorbent body 5) as described above, It is preferable that the chroma C ^* is high compared to the color of the member. As a result, the psychological effect of the color of the fastening member 16 described above can be achieved more reliably.

When the packaging material 15 has a high light transmittance portion with relatively high light transmittance (total light transmittance) such as the transparent portion and a low light transmittance portion with relatively low light transmittance, the fastening member 16 is preferably located in the low light transmissive portion. The high light transmittance portion is a portion where the color of the napkin 1 wrapped in the packaging material 15 can be visually recognized. , the napkin 1 is obstructed.

Based on the knowledge about the individual package 20 described above, a preferred embodiment of the napkin 1 is as follows.
A packaging material 15 for packaging the napkin 1 is arranged on the non-skin facing surface Sb of the napkin 1,
In the packaging material 15, when the napkin 1 is folded together with the packaging material 15 to form an individual package 20, the end portion of the packaging material 15 is positioned on the outer surface of the individual package 20 and stopped at a predetermined position of the packaging material 15. A fastening member 16 is arranged to be worn,
The packaging material 15 has a relatively high light transmittance portion and a relatively low light transmittance portion, and the fastening member 16 is arranged in the low light transmittance portion,
The color of the fastening member 16 is similar to the color of the first colored member (back sheet 4) or the second colored member (absorbent body 5),
When the individual package 20 is viewed, the color of the first colored member (backsheet 4) or the second colored member (absorbent body 5) can be visually recognized through the high light-transmitting portion.

The napkin 1 may contain one or more functional materials selected from the group consisting of cooling agents and antibacterial agents. As described above, the napkin 1 includes the first colored member (back sheet 4) and the second colored member (absorbent body 5), and the psychological effects of the colors of both colored members provide a good feeling of use. Whereas the napkin 1 further contains a functional material, it can be expected to further improve the feeling of use. For example, when a cooling sensation agent is contained as the functional material, the effect of the cooling agent gives the user a cool sensation, a refreshing sensation, a dry sensation, and the like, thereby providing a good usability. In addition, when an antibacterial agent is contained as a functional material, the action of the antibacterial agent suppresses the generation of bad odors caused by bodily fluids, thereby achieving a good feeling during use. In particular, when the colors of both colored members and the effect of the functional material can be associated, for example, the second colored member (absorbent body 5) is blue, while the blue color of the functional material brings about a cooling effect. When the cooling agent that can play is contained, the user visually recognizes the blue color of the napkin 1 and wears the napkin 1 while expecting the cooling effect, so the psychological effect and Combined with the effects actually produced by the functional material, the feeling of use of the napkin 1 can be further improved.
