Description

[Technical field]

[0001] The present invention relates to absorbent articles, sanitary napkins, a family of absorbent articles, and a family of sanitary napkins. [Background technology]

[0002] An absorbent article having a cooling agent is described in, for example, Patent Document 1. The cooling agent may act on a receptor activation channel (TRPM8) in the nerves of the skin, or may lower the surrounding temperature by vaporization heat. When a wearer wears the absorbent article, the cooling agent can come into contact with the wearer's skin. This allows the wearer to feel coolness. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Special Publication No. 2004-528090 Summary of the Invention [Problem to be solved by the invention]

[0004] However, when the cooling agent acts on the receptor activation channel (TRPM8) in the nerves of the skin, the wearer cannot feel the coldness until it comes into direct contact with the wearer's skin. When the cooling agent uses the latent heat of vaporization, the cooling agent removes heat from the skin, which allows the wearer to feel the coldness. Therefore, there is a problem that the wearer cannot easily feel the coldness from the time the absorbent article is put on until the cooling agent actually comes into contact with the skin.

[0005] Therefore, there is a demand from wearers for absorbent articles containing a cooling sensation agent that allows the wearer to feel coolness quickly and easily.

[0006] SUMMARY OF THE PRESENT EMBODIMENT An object of the present invention is to improve upon conventional absorbent articles and to provide an absorbent article which allows the wearer to feel cold more quickly and easily. [Means for solving the problem]

[0007] In order to solve the above-mentioned problems, the absorbent article of the present invention is an absorbent article having a scented cooling agent, and is characterized in that it has a front-to-back direction, a width direction perpendicular to the front-to-back direction, and a thickness direction perpendicular to the front-to-back direction and the width direction, an absorbent body, and a top sheet that is positioned closer to the skin than the absorbent body in the thickness direction, and has a colored area that is visible in yellow from the top sheet side.

[0008] In order to solve the above problem, the group of absorbent articles of the present invention is characterized in that it is a group of absorbent articles including a first absorbent article which is an absorbent article described in any one of claims 1 to 6, a second absorbent article which has a cooling sensation agent and has a colored portion of a first color different from yellow, and a third absorbent article which has a cooling sensation agent and has a colored portion of yellow, the first color, and a second color different from yellow and the first color.

[0009] The absorbent article according to the present invention may include at least the following embodiments, which may be adopted separately or in combination with each other.

[0010] In the absorbent article of aspect 1, the top sheet and the colored portion have compressed portions compressed in the thickness direction, and in a planar view from the thickness direction, the colored portions are respectively arranged in the compressed portions and in uncompressed portions that are not compressed in the thickness direction.

[0011] In the absorbent article of aspect 1, the wearer can visually recognize the colored region three-dimensionally, so that the colored region stands out to the wearer. Therefore, according to the absorbent article of aspect 3, the colored region can be easily caught by the wearer's eyes, and the image of yellow can be reliably recalled by the wearer.

[0012] The absorbent article of embodiment 2 has a volatile substance different from the cooling agent, and the volatile substance has a citrus fruit scent.

[0013] In the absorbent article of embodiment 2, the scent of citrus fruits can evoke images of coolness, freshness, and vitality for the wearer in Thailand.

[0014] The absorbent article of aspect 3 further has a side sheet and a back sheet that form wings, and the sheet located on the skin side of the absorbent body in the thickness direction has a yellow colored portion, while the side sheet and the back sheet are a color different from the yellow of the colored portion.

[0015] The absorbent article of aspect 3 has the ability to conceal menstrual blood by changing color depending on the area, but if menstrual blood flows onto the side sheet, the blood is made noticeable, allowing the wearer to know that it is time to change the absorbent article.

[0016] In the group of absorbent articles of aspect 4, the volatile substance components of the first absorbent article, the volatile substance components of the second absorbent article, and the volatile substance components of the third absorbent article are different from each other, and the scent of the volatile components in the first absorbent article, the scent of the volatile components in the second absorbent article, and the scent of the volatile components in the third absorbent article are different from each other.

[0017] According to the group of absorbent articles constituted by a plurality of absorbent articles of different colors in aspect 4, by changing the scent in addition to the color, the wearer can have a wider range of product choices depending on his / her mood at the time of purchase.

[0018] The absorbent article of claim 1 is the sanitary napkin of aspect 5, in which a colored region that is visible in yellow is arranged closer to the skin than the absorbent body in the thickness direction and overlaps the absorbent body.

[0019] In the sanitary napkin of embodiment 5, when menstrual blood is discharged onto the absorbent body, the ground (background) is yellow and the menstrual blood is red. On the other hand, in the case of a normal napkin, the absorbent article is formed from a white material, so the ground (background) is white and the menstrual blood is red. Therefore, when menstrual blood is discharged onto the absorbent article, the menstrual blood can be concealed by the yellow background.

[0020] The absorbent article of claim 4 is the sanitary napkin of aspect 6, further comprising hip flaps including the side sheets, and in an unfolded state, the anti-slip portion formed on the hip flaps and the yellow colored portion do not overlap in the thickness direction.

[0021] The sanitary napkin of embodiment 6 has the ability to conceal menstrual blood by changing the color depending on the region, but if menstrual blood flows onto the sheet forming the hip flap, the blood is made noticeable, allowing the wearer to know that it is time to change the napkin. Furthermore, the presence of anti-slip devices on the hip flaps prevents wrinkles from forming on the hip flaps when the napkin is worn, making the menstrual blood more noticeable if it does flow. Furthermore, the anti-slip devices fix the absorbent article in place, allowing the absorbent article to fit along the buttocks on the outer side in the width direction.

[0022] In the absorbent article group of aspect 7, the first sanitary napkin has a volatile substance different from the cooling agent, the second sanitary napkin has a volatile substance different from the cooling agent, the third sanitary napkin has a volatile substance different from the cooling agent, the components of the volatile substance of the first sanitary napkin, the components of the volatile substance of the second sanitary napkin, and the components of the volatile substance of the third sanitary napkin are different from each other, and the scent of the first sanitary napkin, the scent of the second sanitary napkin, and the scent of the third sanitary napkin are different from each other.

[0023] According to the group of sanitary napkins consisting of a plurality of sanitary napkins of different colors in aspect 7, by varying the scent in addition to the color, the wearer can have a wider range of product choices depending on her mood at the time of purchase. Effect of the Invention

[0024] The absorbent article according to the present invention has a cooling agent that has a smell and has a colored area that is visible in yellow from the top sheet side. In Thailand, the smell of the cooling agent and the yellow color can evoke the image of yellow chrysanthemum tea, which has an image of cooling the body. As a result, the absorbent article according to the present invention can evoke a cool image for Thai people. This allows the wearer to recognize that the absorbent article provides a refreshing feeling and to consciously make the skin sensitive, so that the wearer can feel the coolness of the cooling agent more quickly than if the wearer were unconscious. Furthermore, in Thailand, yellow can give an image of freshness and an image of vitality. Therefore, according to the absorbent article according to the present invention, it can give an image of freshness and an image of vitality to the wearer in Thailand. Furthermore, since images created by the human brain can affect the human senses, the absorbent article according to the present embodiment can improve the cooling effect and improve the mood of the wearer.

[0025] According to the group of absorbent articles of the present invention, which is composed of a plurality of absorbent articles of different colors, the image that the wearer imagines can be changed by changing the color. Therefore, according to the group of absorbent articles of the present invention, the image of the cool feeling can be changed among the plurality of absorbent articles of different colors, and the range of product choices for the wearer can be expanded.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0027] [Embodiment] The following embodiment relates to an absorbent article shown in the attached drawings, and includes not only essential configurations of the invention, but also optional and preferred configurations. Hereinafter, an embodiment of a napkin 10, which is an example of an absorbent article according to the invention, will be described with reference to the attached drawings. In each drawing, the colored area CA, which will be described later, is colored in light black.

[0028] [First embodiment] A sanitary napkin 10, which is an example of an absorbent article, is formed elongated in the front-to-rear direction Y as shown in Figures 1 to 3, and comprises at least an absorbent body 20, a skin side sheet 30, a back sheet 40 (see Figures 2 and 3), and a cooling layer 50 (see Figure 2).

[0029] Fig. 1 is a plan view of a napkin 10, which is an example of an absorbent article according to a first embodiment of the present invention, seen from the skin side. Fig. 2 is a cross-sectional view taken along the line AA in Fig. 1. Fig. 3 is a plan view showing multiple regions of an absorbent body 20 included in the napkin 10 shown in Fig. 1.

[0030] The direction in which the napkin 10 extends is the front-rear direction Y. In other words, the front-rear direction Y is the longitudinal direction. Furthermore, in the napkin 10, the direction that intersects (more specifically, perpendicular to) the front-rear direction Y is the width direction X. In other words, the width direction X is the short side direction. Furthermore, in the napkin 10, the direction that intersects (more specifically, perpendicular to) the width direction X and the front-rear direction Y is the thickness direction Z. Furthermore, one side of the thickness direction Z is the skin-facing side that faces the wearer's skin (hereinafter simply referred to as the "skin side"), and the other side of the thickness direction Z is the non-skin-facing side that faces the wearer's clothing (hereinafter simply referred to as the "non-skin side").

[0031] 3, the napkin 10 has a longitudinal centerline P that bisects the length in the width direction X. The napkin 10 is formed substantially symmetrically with respect to the longitudinal centerline P.

[0032] The napkin 10 comprises a central region 10M, a front region 10F, and a rear region 10R in the front-to-rear direction Y. The central region 10M according to this embodiment is a region including an excretory-opening-facing region 10E that faces the excretory opening (e.g., the vaginal opening) of the wearer when the napkin 10 is worn. The central region 10M is a region that is located in the center of the front-to-rear direction Y when the napkin 10 is divided into three equal parts in the front-to-rear direction Y, for example.

[0033] The front region 10F is a region located on the front side, that is, on one side of the central region 10M, in the front-to-back direction Y. The front region 10F is a region located on the front side in the front-to-back direction Y when the napkin 10 is divided into three equal parts in the front-to-back direction Y, for example.

[0034] The rear region 10R is a region located on the other rear side of the central region 10M in the front-to-back direction Y. The rear region 10R is a region located on the rear side in the front-to-back direction Y when the napkin 10 is divided into three equal parts in the front-to-back direction Y, for example.

[0035] The absorbent body 20 is formed, for example, in a rectangular shape that is elongated in the front-rear direction Y. The absorbent body 20 is disposed in at least a central region 10M. The absorbent body 20 according to this embodiment extends from the central region 10M to one side in the front-rear direction Y, and also extends from the central region 10M to the other side in the front-rear direction Y.

[0036] The absorbent body 20 includes an absorbent material for absorbing liquid, such as wood fluff pulp and superabsorbent polymer particles (SAP) as are commonly used in the art.

[0037] The absorbent body 20 comprises an absorbent core containing an absorbent material, and a core wrap sheet that covers the absorbent core (neither is shown).

[0038] The core wrap sheet is formed, for example, from a hydrophilic or liquid-dispersive fibrous nonwoven fabric that covers the entire absorbent core.

[0039] The absorbent body 20 has an absorbent core and is therefore capable of absorbing bodily waste (more specifically, menstrual blood, etc.). Such an absorbent body 20 is disposed between the skin side sheet 30 and the back sheet 40 in the thickness direction Z, and is joined to the skin side sheet 30 and the back sheet 40.

[0040] 3, the absorbent body 20 according to this embodiment includes an absorbent body central region 20M, an absorbent body front region 20F, and an absorbent body rear region 20R in the front-rear direction Y. Each of the absorbent body central region 20M, the absorbent body front region 20F, and the absorbent body rear region 20R described above is a region formed by dividing the absorbent body 20 into thirds in the front-rear direction Y. When the napkin 10 has wings 61 described later, the region where the wings 61 are arranged may be the absorbent body central region 20M, the region in front of the absorbent body central region 20M may be the absorbent body front region 20F, and the region behind the absorbent body central region 20M may be the absorbent body rear region 20R.

[0041] The absorbent body central region 20M according to this embodiment is a region including the excretory-opening facing region 10E that faces the excretory opening (for example, the vaginal opening) of the wearer when the absorbent body is worn (see FIG. 1).

[0042] Moreover, the absorbent body 20 according to this embodiment includes an inner region 20I and a pair of outer regions 20S in the width direction X. The inner region 20I and the pair of outer regions 20S described above are each formed by dividing the absorbent body 20 into thirds in the width direction X.

[0043] The inner region 20I according to this embodiment is a region including the excretory-opening facing region 10E that faces the excretory opening (for example, the vaginal opening) of the wearer when the diaper is worn (see FIG. 1).

[0044] As shown in FIG. 2, the skin side sheet 30 is located on the skin side of the absorbent body 20, and is composed of, for example, a top sheet 30a and a second sheet 30b.

[0045] The top sheet 30a is located on the skin side of the absorbent body 20 in the thickness direction Z, and is liquid permeable. The top sheet 30a is made of a liquid-permeable fibrous nonwoven fabric. The top sheet 30a according to this embodiment is made of a white fibrous nonwoven fabric.

[0046] The second sheet 30b is disposed between the top sheet 30a and the absorbent body 20 in the thickness direction Z. The second sheet 30b is liquid permeable. The second sheet 30b according to this embodiment is formed of a yellow fibrous nonwoven fabric.

[0047] The back sheet 40 is disposed on the non-skin side of the absorbent body 20. The back sheet 40 is liquid impermeable. One of the outer surfaces of the back sheet 40 in the thickness direction Z is disposed on the closest side to the skin of the napkin 10, and forms a non-skin facing surface that faces the wearer's underwear. The back sheet 40 according to this embodiment is formed from a white material.

[0048] As shown in Figs. 2 and 3, the top sheet 30a and the back sheet 40 extend relative to the absorbent body 20 in both the front-rear direction Y, and the extended portions are bonded with an adhesive such as a hot melt adhesive.

[0049] The napkin 10 according to this embodiment further includes a pair of side sheets 60. The side sheets 60 according to this embodiment are formed in white color.

[0050] A pair of wings 61 are formed by a pair of side sheets 60 and the back sheet 40 on each of the outer sides in the width direction X of both side edge portions 20c, 20d of the absorbent body 20.

[0051] In the front region 10F, a pair of side flaps 62F are formed on the outer sides in the width direction X of both side edge portions 20c, 20d of the absorbent body 20, respectively.

[0052] Furthermore, in the rear region 10R, a pair of side flaps 62R are formed on the outer sides in the width direction X of both side edge portions 20c, 20d of the absorbent body 20, respectively.

[0053] The pair of wings 61 and the pair of side flaps 62F, 62R are formed by joining the side sheet 60 and the back sheet 40 by known joining means such as a hot melt adhesive (not shown).

[0054] The anti-slip portion 70 prevents the napkin 10 from slipping relative to clothing such as underwear when worn. The anti-slip portion 70 is disposed on the non-skin side of the back sheet 40 described above.

[0055] The anti-slip portion 70 is formed, for example, from a pressure sensitive adhesive or a pressure sensitive adhesive.

[0056] The slippage prevention portion 70 according to this embodiment is formed by a plurality of (six in this embodiment) linear slippage prevention regions 71 extending linearly along the front-rear direction Y. All of the linear slippage prevention regions 71 are disposed so as to overlap with the absorbent body 20 in the thickness direction Z, as shown in Figs. 3 and 4.

[0057] Moreover, the napkin 10 according to this embodiment further comprises a cooling layer 50 containing a cooling agent, as shown in Fig. 2. In other words, the napkin 10 comprises a cooling agent.

[0058] Cooling agents include menthol (e.g., l-menthol) and its derivatives (e.g., menthyl lactate), methyl salicylate, and essential oils derived from plants (e.g., mint, eucalyptus, nutmeg). Cooling agents may also lower the surrounding temperature by the heat of vaporization. Examples of such cooling agents include alcohols (e.g., methanol and ethanol).

[0059] The cooling layer 50 is disposed between the top sheet 30a and the second sheet 30b in the thickness direction Z, as shown in Fig. 2. The cooling layer 50 may be formed, for example, by applying a cooling agent to the non-skin side of the top sheet 30a.

[0060] In the napkin 10 according to this embodiment, the colored area CA is formed by the cooling layer 50. That is, the entire cooling layer 50 is formed as a colored portion CA1 colored yellow. The yellow color of the cooling layer 50 can be seen through the top sheet 30a. Note that the colored portion CA1 does not need to be yellow, as long as it is seen as yellow when viewed by a wearer through the top sheet 30a.

[0061] In the napkin 10 according to this embodiment, the colored area CA is provided over the entire area of ​​the cooling layer 50, making it easy for the wearer to visually recognize the colored area CA. Furthermore, the wide area of ​​the colored area CA (colored portion CA1) reminds the wearer of a cooling sensation, which makes it easier for the wearer to focus their attention on a wide area of ​​the skin, making it easier for the wearer to feel coolness even before putting on the napkin.

[0062] Moreover, the cooling layer 50 according to this embodiment is provided with a volatile substance different from the cooling agent. The volatile substance has a scent such as essential oil derived from citrus fruits (e.g., yuzu, mandarin orange, etc.) or essential oil derived from chrysanthemum. The volatile substance may be formed by spraying a fragrance onto the surface of the above-mentioned member constituting the napkin 10.

[0063] In the napkin 10 according to this embodiment, the colored area CA1, which is the colored region CA, is provided in the cooling layer 50 arranged on the non-skin facing side of the top sheet 30a. The skin facing surface of the top sheet 30a, which is located on the skin facing side, is the surface that comes into contact with the sensitive skin of the wearer, but by arranging the colored portion CA1 on the non-skin facing side of the top sheet 30a in the thickness direction Z, it is possible to prevent the coloring agent that colors the colored portion CA1 from coming into direct contact with the skin, thereby making it easier for the wearer to feel cool while providing a sense of security to the wearer.

[0064] Moreover, the colored portion CA1 according to this embodiment is provided over the entire area of ​​the cooling layer 50 in the front-rear direction Y and the width direction X. Therefore, the area of ​​the colored area CA can be made large, so that the wearer can easily see the colored area CA. Furthermore, the large area of ​​the colored area CA can evoke a feeling of coolness, so that the wearer can easily feel the coolness before wearing the garment. Note that the colored portion CA1 is not limited to the entire area of ​​the cooling layer 50, and may be provided over a portion of the cooling layer 50.

[0065] The colored portion CA1 may be formed by impregnating the fibrous nonwoven fabric with paint.

[0066] The napkin 10 according to this embodiment also has a non-colored area CA2 visible from the top sheet 30a side around the colored area CA, as shown in Fig. 2. Moreover, the non-colored area CA2 according to this embodiment is, for example, white in color.

[0067] The napkin 10 according to this embodiment has a reminiscent information portion 80 composed of characters or a design that can evoke a cool sensation. In the napkin 10 according to this embodiment, the reminiscent information portion 80 is formed, for example, on the top sheet 30a. Therefore, the wearer can visually recognize the reminiscent information portion 80 from the top sheet 30a side. The reminiscent information portion 80 according to this embodiment is formed by a compressed portion 91.

[0068] In the napkin 10 according to this embodiment, the cooling sensation layer 50 and the compressed portion 91 are arranged so as to overlap in the thickness direction Z. In the thickness direction Z, the thickness of the top sheet 30a in the compressed portion 91 is thinner than the thickness of the top sheet 30a in the non-compressed portion 92 adjacent to the compressed portion 91. Therefore, compared to a napkin in which the compressed portion 91 is not formed, the cooling sensation agent contained in the cooling sensation layer 50 can easily pass through the thin top sheet 30a in the compressed portion 91. Therefore, the cooling sensation agent of the napkin 10 according to this embodiment can easily move from the cooling sensation layer 50 through the top sheet 30a to the outside on the skin side, so that the wearer can easily feel the coolness quickly.

[0069] In addition, even in the portion where the compressed portion 91 and the cooling layer 50 do not overlap in the thickness direction Z, the volatilized cooling agent can move inside the napkin 10 and then pass through the top sheet 30a of the compressed portion 91. Moreover, even in the portion where the compressed portion 91 and the cooling layer 50 do not overlap in the thickness direction Z, the volatilized cooling agent can pass through the top sheet 30a of the non-compressed portion 92 and move to the outside on the skin side.

[0070] Moreover, the compressed portion 91 according to this embodiment has a highly compressed portion 911 and a low compressed portion 912 that is shallower in depth in the thickness direction Z than the highly compressed portion 911 .

[0071] As described above, the napkin 10 according to this embodiment is an absorbent article having a cooling agent with a smell. In Thailand, the smell of the cooling agent and the yellow color can evoke the image of yellow chrysanthemum tea, which has an image of cooling the body. As a result, the napkin 10 according to this invention can evoke a cool image for Thai people. This allows the wearer to recognize that the napkin 10 provides a refreshing feeling, and the wearer's skin can be made sensitive in his or her consciousness, so that the wearer can feel the coolness of the cooling agent more quickly than if he or she were unconscious. Furthermore, in Thailand, yellow can give an image of freshness and can give an image of vitality. Therefore, according to the napkin 10 according to this embodiment, the wearer in Thailand can be given an image of freshness and can be given an image of vitality. Furthermore, since images created by the human brain can affect human senses, the napkin 10 according to this embodiment can improve the cooling effect and improve the mood of the wearer.

[0072] Furthermore, in the napkin 10 according to this embodiment, a colored area CA that is visible in yellow is arranged closer to the skin than the absorbent body 20 in the thickness direction Z and overlaps the absorbent body 20. Therefore, in the napkin 10 according to this embodiment, when menstrual blood is discharged into the absorbent body 20, the second sheet 30b, which serves as the background, appears yellow and the menstrual blood appears red. On the other hand, in a normal napkin, the absorbent article is formed from a white material, so the background is white and the menstrual blood is red. Therefore, when menstrual blood is discharged into the absorbent article, the menstrual blood can be concealed by the yellow background.

[0073] In addition, in the napkin 10 according to this embodiment, the top sheet 30a and the colored portion CA1 have a compressed portion 91 compressed in the thickness direction Z, and in a plan view seen from the thickness direction Z, the colored portion CA1 is disposed in the compressed portion 91 and the non-compressed portion 92 not compressed in the thickness direction Z. Therefore, in the napkin 10 according to this embodiment, the wearer can visually recognize the colored region three-dimensionally, so that the colored region can be made to stand out to the wearer. Therefore, according to the napkin 10 according to this embodiment, the colored region CA can be easily seen by the wearer, and the image of yellow can be reliably evoked by the wearer.

[0074] The napkin 10 according to this embodiment further has a side sheet 60 forming a wing 61, and while there is a yellow colored area CA1 on the sheet located on the skin side of the absorbent 20 in the thickness direction Z, the side sheet 60 is a color (white) different from the yellow of the colored area CA1. Therefore, the napkin 10 according to this embodiment has the ability to conceal menstrual blood by changing the color depending on the area, but if menstrual blood flows onto the side sheet 60, the blood is made noticeable, allowing the wearer to know that it is time to change it.

[0075] Furthermore, the napkin 10A according to this embodiment further comprises hip flaps 63 including side sheets 60, and the slip prevention portion 70A formed on the hip flaps 63 does not overlap with the yellow colored portion CA1 in the thickness direction Z. Therefore, the napkin 10A according to this embodiment has the ability to conceal menstrual blood by changing color depending on the region, but even if menstrual blood flows onto the sheet forming the hip flaps 63, the menstrual blood is made noticeable, allowing the wearer to know that it is time to change the napkin.

[0076] In the napkin 10 according to the embodiment described above, the colored portion CA1 is provided in the cooling layer 50. However, the napkin 10 according to the present embodiment is not limited to this. The colored portion CA1 may be provided, for example, in the top sheet 30a, the second sheet 30b, the absorbent body 20 (for example, a core wrap sheet), the back sheet 40, or the side sheet 60. Furthermore, the colored portion CA1 may be provided in only one of the above-mentioned multiple members, or in multiple members.

[0077] Moreover, the colored portion CA1 may be provided over the entire area of ​​the member on which the colored portion CA1 is provided, or may be provided in a partial area.

[0078] Furthermore, when colored portions CA1 are provided in multiple members, for example, a colored region that is visible in yellow when viewed from the top sheet 30a side may be configured by arranging the colored portions CA1 so that they do not overlap in the thickness direction Z. Of course, the napkin 10 according to this embodiment is not limited to this, and the colored portions CA1 may be arranged so that they overlap in some areas in the thickness direction Z, thereby providing a shading of yellow when viewed from the top sheet 30a side.

[0079] In addition, in the napkin 10 according to this embodiment, the volatile substance is provided in the cooling layer 50. However, the napkin 10 according to this embodiment is not limited to this. The volatile substance may be provided, for example, in the top sheet 30a, the second sheet 30b, the absorbent body 20 (for example, a core wrap sheet), the back sheet 40, or the side sheet 60. Furthermore, the volatile substance may be provided in only one of the above-mentioned multiple components, or in multiple components.

[0080] Next, the package 200 for the napkin 10 will be described with reference to Fig. 5. Fig. 5 is a plan view showing the packaged state of the napkin 10 shown in Fig. 1. The package 200 for the napkin 10 has the napkin 10 and a packaging sheet 250 for individually packaging the napkin 10. In other words, the napkin 10 is individually packaged by the packaging sheet 250.

[0081] In addition, the colored area CA of the packaging body 200 may be visible from the outside through the packaging sheet 250 before the packaging sheet 250 is opened. According to such a packaging body 200, the wearer is reminded of a cool sensation even before the wearer opens the packaging sheet 250, so that the wearer can easily feel the coolness more quickly.

[0082] Moreover, packaging reminiscent information 255 consisting of at least one of characters, colors, and designs that can evoke a cool sensation is formed on the packaging sheet 250. According to such a package 200, the wearer can visually recognize the packaging reminiscent information 255 before opening the packaging sheet 250, so that the wearer can more quickly feel the coolness.

[0083] Yellow-reminiscent information consisting of at least any one of characters, colors, and designs that can evoke the color yellow may be formed on the packaging sheet 250. With such a packaging body 200, the wearer can visually recognize the yellow-reminiscent information before opening the packaging sheet 250, so that the wearer can more quickly feel the coldness.

[0084] The yellow color evocative information may be, for example, characters and / or designs of citrus fruits (one example is "yuzu").

[0085] Furthermore, the napkin 10 may have one or more folds extending in the width direction X. For example, in a packaged state in which the napkin 10 is packaged in the packaging sheet 250, the napkin 10 may be folded using the folds as base points. In the packaged state shown in Fig. 5, the napkin 10 is folded at two folds FL1 and FL2.

[0086] [Second embodiment] Next, a napkin 10A according to a second embodiment will be described with reference to Figures 6 and 7. In the configuration of the napkin 10A according to the second embodiment, the same components as those of the napkin 10 according to the first embodiment will be given the same reference numerals and will not be described again, and only the different components will be described below.

[0087] Furthermore, the absorbent 20 of the napkin 10A in this embodiment is partitioned into an absorbent front region 20F, an absorbent central region 20M, and an absorbent rear region 20R by a pair of independently formed linear components 913 that extend in an arc shape in the width direction X, among the multiple linear components 913.

[0088] Furthermore, the napkin 10A according to this embodiment has hip flaps 63 formed by the side sheets 60 and the back sheet 40. The hip flaps 63 are disposed in the rear region 10R. Moreover, the hip flaps 63 are larger in the width direction X than the side flaps 62F formed in the front region 10F.

[0089] The slip prevention portion 70A according to this embodiment is formed by a linear slip prevention region 71 and a second region 72 that is different from the linear slip prevention region 71. The second region 72 is disposed on the non-skin side of the hip flap 63. In other words, the second region 72 is formed in the hip flap 63.

[0090] Furthermore, in the napkin 10A according to this embodiment, the colored area CA is visible from the back sheet 40 side. This increases the opportunities for the wearer to visually recognize the colored area CA, which can better evoke a sense of coolness in the wearer. Furthermore, when the napkin 10A is disposed of, it is folded so that the top sheet 30a is on the inside and the back sheet 40 is on the outside. This allows the wearer to visually recognize the colored area CA even after use. As a result, the napkin 10A according to this embodiment can easily make the wearer feel cool even after use.

[0091] Furthermore, as shown in FIG. 7, in the thickness direction Z of the napkin 10A according to this embodiment, the hip flaps 63 and the colored portion (colored area CA) CA1 do not overlap each other.

[0092] The napkin 10A according to this embodiment further includes hip flaps 63 including side sheets 60, and in the unfolded state, the slip prevention portion (second region 72) formed on the hip flaps 63 does not overlap with the yellow colored portion CA1 in the thickness direction Z. Therefore, the napkin 10A according to this embodiment has the ability to conceal menstrual blood by changing the color depending on the region, and if menstrual blood flows to the side sheets 60 forming the hip flaps 63, the menstrual blood is made noticeable, so that the wearer can know that it is time to change the napkin. Furthermore, the presence of the slip prevention portion (second region 72) on the hip flaps 63 prevents wrinkles from forming on the hip flaps 63 when worn, so that if menstrual blood flows, the menstrual blood can be made more noticeable. Moreover, since the slip prevention portion (second region 72) fixes the napkin 10, the napkin 10 can be fitted along the buttocks on the outer side in the width direction.

[0093] [Third embodiment] Next, a group of absorbent articles 100 according to a third embodiment will be described with reference to Fig. 8. Fig. 8 is a plan view of the group of absorbent articles 100 according to the third embodiment of the present invention, viewed from the skin side. In the group of absorbent articles 100 according to the third embodiment, reference numeral 10 denotes the napkin according to the first embodiment. In the group of absorbent articles 100 according to the third embodiment, the same components as those of the absorbent article according to the first embodiment are denoted by the same reference numerals and their explanations are omitted, and different components will be described below.

[0094] Reference numeral 10 denotes the napkin of the first embodiment described above. As described above, the napkin 10 has a yellow colored portion (colored area CA) CA1. Reference numeral 101 denotes a napkin that is a second absorbent article that contains a cooling agent and has a colored portion CA12 that is green (first color) different from yellow. Reference numeral 102 denotes a napkin that is a third absorbent article that contains a cooling agent and has a colored portion CA13 that is yellow, a first color, and a light blue (third color) different from yellow and the second color. In other words, the absorbent article group 100 according to this embodiment is composed of three types of napkins that have colored portions CA1, CA12, and CA13 of three different colors.

[0095] According to the absorbent article group 100 of this embodiment, the color of the colored portion CA1 of the napkin 10, which is the first absorbent article, the color of the colored portion CA12 of the napkin 101, which is the second absorbent article, and the color of the colored portion CA13 of the napkin 102, which is the third absorbent article, are different from each other. Therefore, according to the absorbent article group 100 consisting of multiple napkins (absorbent articles) 10, 101, and 102 of different colors, the image evoked by the wearer can be changed by changing the color. For example, in Thailand, if a wearer has an image of light blue being the coolest, yellow being the second coolest, and green being the third coolest, the napkins 10, 101, and 102 of different colors can be selected depending on the external environment such as the temperature on the day the napkin is purchased. Therefore, according to the absorbent article group 100 of the present invention, the image of coolness can be changed among multiple napkins (absorbent articles) 10, 101, and 102 of different colors, and the wearer's range of product selection can be expanded.

[0096] As described above, the napkin 10 contains a volatile substance different from the cooling agent, and the volatile substance has a scent of, for example, citrus fruits (one example is "yuzu").

[0097] On the other hand, the napkin 101 has a volatile substance different from the cooling agent.

[0098] On the other hand, the napkin 102 has a volatile substance different from the cooling agent.

[0099] The napkin 10, which is the first absorbent article, has a volatile substance different from the cooling agent, the napkin 101, which is the second absorbent article, has a volatile substance different from the cooling agent, the napkin 102, which is the third absorbent article, has a volatile substance different from the cooling agent, the components of the volatile substance of the first absorbent article, the components of the volatile substance of the second absorbent article, and the components of the volatile substance of the third absorbent article are different from each other, and the scent of the first absorbent article, the scent of the second absorbent article, and the scent of the third absorbent article are different from each other. As a result, according to the absorbent article group 100 of this embodiment, by further changing the scent in addition to the color, it is possible to expand the range of products (napkins 10, 101, 102) that the wearer can choose depending on, for example, the mood at the time of purchase.

[0100] The absorbent article according to the above embodiment is described as being napkins 10 and 10A. However, the absorbent article according to the embodiment is not limited to napkins 10 and 10A, and can be applied to panty liners, incontinence pads, and absorbent pads as long as the technical effects of the present invention are achieved. Of course, the absorbent article according to the embodiment is not limited to these, and can be applied to disposable diapers. For example, it can be applied to pants-type disposable diapers, and can also be applied to open-type disposable diapers.

[0101] The above describes the embodiments of the absorbent articles 10 and 10A and the embodiment of the absorbent article group 100 according to the present invention, but the present invention is not limited to the embodiments, and various modifications are possible within the scope of the gist of the present invention. In addition, the present invention also includes a configuration in which some of the components of the above-mentioned embodiments are appropriately combined. Such modifications that do not depart from the scope of the gist are also included in the technical scope of the present invention, and this is clear to a person skilled in the art from the description of the scope of claims for utility model registration.

[0102] In the absorbent articles 10, 10A, etc. of this embodiment, yellow is a color included in numbers 2 to 4 of the 24 color chips classified by the Ostwald color wheel, green is a color included in numbers 1 and 20 to 24 of the 24 color chips classified by the Ostwald color wheel, and light blue is a color included in numbers 13 to 19 of the 24 color chips classified by the Ostwald color wheel.
