Outdoors, there are many opportunities for direct exposure to sunlight. The wearer or a caregiver such as a mother tends to feel comfortable that the part covered by the absorbent article is protected from the sun, even though the wearer with the absorbent article is exposed to the sun.

However, at least in the portion of the outer body arranged in the waist region that overlaps the absorbent main body in the thickness direction, a plurality of sheets overlap each other, so it is difficult for ultraviolet rays contained in sunlight to pass through, but the absorbent of the outer body is In the non-overlapping portion, which does not overlap with the main body in the thickness direction, there is a problem that ultraviolet light easily penetrates and damages the wearer's skin. When chemicals such as sunscreen are used to protect the wearer's skin, the area covered by the absorbent article has many areas that are sensitive to stimulation, so the skin of the wearer (especially infants) may be irritated. There is a risk of giving

In addition, when the absorbent article is exposed to the infrared rays contained in the sunlight, the body temperature of the part covered with the absorbent article rises, which reduces the wearer's comfort. Moreover, since a high-temperature object emits infrared rays, the same problem occurs not only outdoors but also in an environment where it is not directly exposed to sunlight (for example, inside a car in summer).

(1) Overview of Embodiments At least the following matters will become clear from the description of this specification and the accompanying drawings.

An absorbent article according to one aspect includes a front-rear direction, a width direction orthogonal to the front-rear direction, a thickness direction, a waist region covering the waist of a wearer, and positioned inside the waist region in the front-rear direction. The absorbent article includes a crotch region, an absorbent main body having an absorbent body disposed at least in the crotch region, and an outer body disposed at least in the waist region. The outer body has a non-overlapping portion that does not overlap with the absorbent main body in the thickness direction. The non-overlapping portion is provided with a protection area for blocking ultraviolet rays.

Accordingly, in the non-overlapping portion through which ultraviolet rays are easily transmitted, the amount of ultraviolet rays reaching the wearer's skin can be reduced by the protective region. Since it is possible to make the wearer of the absorbent article less likely to be affected by ultraviolet rays, adverse effects on the wearer caused by the environment can be reduced.

According to a preferred aspect, the protective region may have a region where the UV shielding rate is 60% or more.

As a result, the amount of ultraviolet rays reaching the wearer's skin can be reduced by 60% or more, so that the wearer of the absorbent article is less likely to be affected by ultraviolet rays.

An absorbent article according to one aspect includes a front-rear direction, a width direction perpendicular to the front-rear direction, a thickness direction, a waist region covering the waist of a wearer, and a position inside the waist region in the front-rear direction. an absorbent body disposed at least in the crotch region and having an absorbent body; and an outer body disposed at least in the waist region. The outer body has a non-overlapping portion that does not overlap with the absorbent main body in the thickness direction. The non-overlapping portion is provided with a protective region having a heat shielding property.

Accordingly, since the non-overlapping portion is provided with a protective region having a heat shielding property, the portion covered with the protective region can suppress an increase in body temperature of the wearer caused by the environment. Therefore, adverse effects on the wearer due to the environment can be reduced.

According to a preferred aspect, the exterior body includes an inner sheet having a contact surface that contacts the wearer's skin, an outer sheet that is arranged closest to the non-skin surface side in the waist region, and the protective region. and a constituent protective layer. The non-overlapping portion may include a region in which only three sheet layers are present, in which the protective layer, the outer sheet, and the inner sheet are laminated in the thickness direction.

In the region where only three layers of laminated sheets exist, if no protective layer exists, the wearer's skin can only be covered with two layers of laminated sheets of the outer sheet and the inner sheet, so that the wearer is protected from the environment. particularly susceptible. Therefore, the existence of the protective layer on the portion that is likely to be affected by the environment makes it difficult to be affected by the environment.

According to a preferred aspect, the exterior body includes an inner sheet having a contact surface that contacts the wearer's skin, an outer sheet that is arranged closest to the non-skin surface side in the waist region, and the protective region. and a constituent protective layer. The protective layer may be arranged between the inner sheet and the outer sheet.

Thereby, since the protective layer is not arranged on the non-skin surface side of the outer sheet, it is possible to make the protective layer less likely to be damaged. In addition, since the protective layer is not arranged closer to the skin than the inner sheet, direct contact of the protective layer with the wearer's skin can be suppressed.

According to a preferred aspect, the exterior body may have a protective layer forming the protective region. The protective layer may be composed of a film.

Since the protective layer is composed of the film, the rigidity of the exterior body is increased, and the exterior body can be made difficult to tear.

According to a preferred aspect, the film may be folded back using the front-rear outer edge of the exterior body as a fold line. The absorbent article may have a region where the films overlap each other in the thickness direction.

In the area where the films overlap in the thickness direction, when the protective layer blocks ultraviolet rays, the ultraviolet ray shielding effect can be increased compared to the area where the films do not overlap, and the protective layer has a heat shielding effect. , the heat shielding effect can be made higher. In addition, the rigidity in the vicinity of the outer edge of the exterior body is increased, so that the vicinity of the outer edge of the exterior body can be made difficult to bulge. As a result, it is possible to suppress reduction in the area of the wearer's body covered by the outer body, and to reduce adverse effects on the wearer caused by the environment.

According to a preferred aspect, the film may not be folded back using the front-rear outer edge of the exterior body as a fold line.

As a result, the films do not overlap each other in the vicinity of the outer edge of the outer covering, so that the rigidity in the vicinity of the outer edge of the outer covering does not increase, and deterioration of the comfortability of the absorbent article can be suppressed.

According to a preferred aspect, the exterior body may have an elastic member having stretchability. The film may have a design area on which a design is applied. The film may be arranged on the non-skin surface side of the elastic member.

Since the visibility of the design is not hindered by the elastic member, deterioration of the visibility of the design can be prevented.

According to a preferred aspect, the film may be provided with ink. The dot area ratio of the ink may be 60% or more.

Inks can further reduce the amount of UV radiation reaching the wearer's skin. Since it is possible to make the wearer of the absorbent article less likely to be affected by ultraviolet rays, adverse effects on the wearer caused by the environment can be reduced.

According to a preferred aspect, the exterior body may have a protective layer forming the protective region. The protective layer may be composed of ink disposed on the exterior body.

As a result, compared to the case where the protective layer is made of a separate member, the rigidity of the protective area does not increase, and the comfort of wearing the absorbent article can be maintained.

According to a preferred aspect, the exterior body has an inner sheet having a contact surface that contacts the wearer's skin, and an outer sheet that is arranged on the outermost non-skin surface side of the exterior body. good. The ink disposed on the inner sheet may constitute the protective layer.

Thereby, since the protective layer is not arranged on the non-skin surface side of the outer sheet, it is possible to make the protective layer less likely to be damaged.

According to a preferred aspect, in a plan view of the absorbent article, in the non-overlapping portion, the ink may be arranged entirely from one outer side portion of the outer covering body to the other outer outer side portion of the outer covering body. .

As a result, adverse effects on the wearer due to the environment can be reduced from one outer portion of the outer body to the other outer portion.

According to a preferred aspect, the exterior body includes a first sheet having a design, a second sheet disposed closer to the skin surface than the first sheet, and having the ink disposed thereon, may have

As a result, since the first sheet is arranged on the non-skin side of the second sheet, the visibility of the design applied to the first sheet is not hindered by the ink arranged on the second sheet. It is possible to prevent the visibility of the design from deteriorating.

According to a preferred aspect, in the protective region, a first ink layer in which a first ink is arranged as the ink and a second ink layer in which a second ink is arranged as the ink overlap in the thickness direction. may have a region where

As a result, in the region where the first ink layer and the second ink layer overlap, when the protective layer blocks ultraviolet rays, the ultraviolet shielding effect can be further enhanced compared to a single ink layer. When the protective layer has a heat shielding effect, the heat shielding effect can be enhanced. This can further reduce adverse effects on the wearer caused by the environment.

According to a preferred aspect, the ink may contain a material that blocks ultraviolet rays.

In addition to the shielding property of the ink itself, the ultraviolet shielding effect can be improved by the ultraviolet shielding material, so that the wearer of the absorbent article can be made less susceptible to the ultraviolet rays.

In addition, since the non-overlapping portion NR is provided with a protective region PR having a heat shielding property, the portion covered with the protective region PR suppresses an increase in body temperature of the wearer caused by the environment. can. Therefore, it is possible to protect the wearer and reduce adverse effects on the wearer caused by the environment.

The non-overlapping portion NR is provided with a region where there are only three sheet layers (that is, fewer layers NR1) in which the protective layer 80, the outer sheet OS, and the inner sheet IS are laminated. Here, if the protective layer 80 does not exist in the region where the minority layer NR1 exists, the wearer's skin can only be covered with the two-layer laminated sheet of the outer sheet OS and the inner sheet IS. Especially susceptible to environmental influences. Therefore, the presence of the protective layer 80 in the portion that is likely to be affected by the environment makes it difficult to be affected by the environment.

In addition, since the protective layer 80 is arranged between the inner sheet IS and the outer sheet OS, the protective layer 80 is not arranged on the non-skin surface side T2 of the outer sheet OS. Therefore, the protective layer 80 can be made difficult to be damaged. In addition, since the protective layer 80 is not arranged closer to the skin surface side T1 than the inner sheet IS, direct contact of the protective layer 80 with the wearer's skin can be suppressed, and stuffiness can be reduced.

Moreover, since the protective layer 80 is composed of the film 81, the rigidity of the exterior body 15 is increased, and the exterior body 15 can be made difficult to tear. As a result, it is possible to suppress reduction in the area of the wearer's body covered by the outer body 15, and to reduce adverse effects on the wearer caused by the environment.

In addition, since the film 81 is not folded at the outer edge of the exterior body 15 in the front-rear direction L, the films 81 do not overlap each other in the vicinity of the outer edge of the exterior body 15 in the front-rear direction L. As a result, the rigidity in the vicinity of the outer edge of the exterior body 15 does not increase, and deterioration of the wearing comfort of the absorbent article 1 can be suppressed.

In the following description, the same description as the contents already described will be omitted.

(4.1) Modification 1
As shown in FIG. 5 , in Modification 1, the protective layer 80 is composed of ink (ink layer 85 ) disposed on the exterior body 15 . The exterior body 15 may be the front exterior body 20 or the rear exterior body 30 .

The ink may be placed, for example, by applying it by printing. For example, the ink may be applied using gravure printing, or the ink may be applied using flexographic printing. The ink may be a color ink, for example, any color such as white, black, gray, blue, green, yellow, red, orange, pink, and light blue. By applying ink, the first ink layer 851 and the second ink layer 852, which are the ink layer 85, may be arranged. In embodiments, the protective layer 80 is composed of a first ink layer 851 and a second ink layer 852 .

As shown in FIG. 5B, the first ink layer 851 may be placed on the inner sheet IS. The first ink layer 851 may be placed on the non-skin side T2 of the inner sheet IS (see FIG. 5B), or may be placed on the skin side T1 of the inner sheet IS.

In a plan view of the absorbent article 1, in the non-overlapping portion NR, the ink may be distributed entirely from one outer side portion 15SE of the outer casing 15 to the other outer side portion 15SE of the outer casing 15. FIG. The first ink layer 851 is arranged, for example, from the inner edge of one side joint portion 18 to the inner edge of the other side joint portion 18, so that the ink is applied from one outer portion 15SE to the other outer portion 15SE. may be placed on the entire surface. Thereby, as shown in FIG. 5A, the protection region PR may exist from the inner edge of one side junction portion 18 to the inner edge of the other side junction portion 18 . In addition, ink may be placed over the entire surface of the overlapping portion OR as well as the non-overlapping portion NR.

In addition, as shown in FIG. 5B, the first ink layer 851 may be coated with ink over the entire surface in the front-rear direction L from the outer edge to the inner edge of the inner sheet IS.

It should be noted that "the ink is arranged on the entire surface" means that the so-called ink is applied solidly. For example, it suffices that there is no area intentionally not coated with ink (for example, an area not coated with ink for design reasons). Therefore, when the ink is colored, it is sufficient to confirm with the naked eye that the color is distributed over the entire surface. may

A second ink layer 852 may be disposed on the outer sheet OS. The second ink layer 852 may be arranged on the non-skin side T2 of the outer sheet OS. The second ink layer 852 may be arranged on the skin side T1 of the outer sheet OS.

As shown in FIG. 5, the second ink layer 852 may constitute a designed design area DR. The design is composed of patterns (a combination of figures and colors). The design may consist of, for example, at least one of horizontal stripes, circles, stars, hearts, and the like. Thereby, the outer sheet OS may be designed.

As shown in FIG. 5, in the second ink layer 852, the ink is distributed entirely from one outer side portion 15SE of the outer casing 15 to the other outer side portion 15SE of the outer casing 15 in plan view of the absorbent article 1. may be In the second ink layer 852, the ink may be disposed on the entire surface in the front-rear direction L from the outer edge to the inner edge of the inner sheet IS.

The protection region PR may have a region where the first ink layer 851 and the second ink layer 852 overlap in the thickness direction T. As shown in FIG.

When the second ink layer 852 constitutes the design area DR, the first ink layer 851 may have the same color as the main color of the design area DR in order to maintain the design. Alternatively, the first ink layer 851 may be white.

As described above, in the absorbent article 1 according to Modification Example 1, the protective layer 80 is made of the ink disposed on the exterior body 15, so compared to the case where the protective layer 80 is made of a separate member, , the rigidity of the protective region PR does not increase, and the comfortability of the absorbent article 1 can be maintained.

Moreover, since the protective layer 80 is not arranged on the non-skin surface side T2 with respect to the outer sheet OS, the protective layer 80 can be made difficult to be damaged.

In addition, in the non-overlapping portion NR, the ink is distributed entirely from one outer portion 15SE to the other outer portion 15SE of the outer body 15, so that the wearer is not adversely affected by the environment in the waist region WR. can be reduced.

In particular, when the design includes white, the white color of the design is represented by the white color of the nonwoven fabric without applying ink to the white design portion because the general nonwoven fabric is white. In this case, since no ink is applied to the white design portion, the wearer's skin is likely to be damaged by the sunlight, or the body temperature of the wearer is likely to rise. However, in the absorbent article 1 of Modified Example 2, the protection region PR overlaps the design region DR in the thickness direction T, and the ink is disposed over the entire surface. Also, the wearer can be protected from sunlight, and the adverse effects on the wearer caused by the environment can be reduced.

In addition, since the inner sheet IS on which the ink is arranged is arranged closer to the skin surface side T1 than the outer sheet OS on which the design is applied, the visibility of the design applied to the outer sheet OS is reduced by the inner sheet IS. not disturbed by ink placed in the It is possible to prevent the visibility of the design from deteriorating.

In addition, since the protective region PR has a region in which the first ink layer 851 and the second ink layer 852 overlap in the thickness direction T, in this region the protective layer When 80 shields ultraviolet rays, the ultraviolet shielding effect can be further enhanced, and when the protective layer 80 has a heat shielding effect, the heat shielding effect can be further enhanced. This can further reduce adverse effects on the wearer caused by the environment.

(4.2) Modification 2
Next, modification 2 will be described. In Modification 2, the ink is placed on the film 81 as shown in FIG. The ink may be placed, for example, by applying it by printing. For example, the ink may be applied using gravure printing, or the ink may be applied using flexographic printing. The ink may be a colored ink, such as white, black, gray, blue, green, yellow, red, orange, pink, and light blue.

The protective layer 80 may consist of a film 81 and an ink layer 85 disposed on the film 81 . In Modification 2, the ink layer 85 is arranged on the non-skin surface side T2 of the film 81 . The ink layer 85 may be arranged on the skin surface side T1 of the film 81 .

The film 81 may be folded back using the outer edge 15E in the front-rear direction L of the exterior body 15 as a folding line. Thereby, the absorbent article 1 may have a region where the films 81 overlap each other in the thickness direction T. As shown in FIG. As shown in FIG. 6A, the film 81 may have a folded portion 81a extending inward in the front-rear direction L from the outer edge 15E on the skin surface side T1 of the absorbent body 40. , and a folded portion 85a. The inner edge of the folded portion 81a in the front-rear direction L may be arranged at a position overlapping the absorbent main body 40 in the thickness direction T. As shown in FIG. As a result, the protective layer 80 can be doubled in the non-overlapping portion NR from the outer edge 15E of the exterior body 15 to the absorbent main body 40, thereby further reducing adverse environmental effects on the wearer. .

As shown in FIG. 6B, from a microscopic point of view, the ink layer 85 may be composed of an ink portion 85p where ink exists and a non-ink portion 85n where ink does not exist when ink is arranged by printing. Therefore, when the ink layer 85 is colored, it is sufficient to confirm that the color is distributed over the entire surface with the naked eye. parts may be present. In the ink layer 85, the interval d between the ink portions 85p should be 0.2 mm or less. When the interval d between the ink portions 85p is larger than 0.2 mm, the ink is not applied between the ink portions 85p.

When the ink layer 85 is arranged by printing ink on the film 81, the halftone dot area ratio of the ink may be 20% or more. The dot area ratio of the ink is preferably 40% or more, more preferably 60% or more. The halftone dot area ratio of the ink indicates the ratio of the area of the ink portion 85p per unit area. When the film 81 is solidly coated with ink, the halftone dot area ratio of the ink is 100%.

As described above, in the absorbent article 1 according to Modification 2, in the region where the films 81 overlap each other in the thickness direction T, compared to the region where the films 81 do not overlap, when the protective layer 80 blocks ultraviolet rays, the ultraviolet rays If the protective layer 80 has a heat shielding effect, the heat shielding effect can be further enhanced. In addition, the rigidity near the outer edge 15E of the exterior body 15 is increased, and the vicinity of the outer edge 15E of the exterior body can be made less likely to become loose. As a result, it is possible to suppress reduction in the area of the wearer's body covered by the outer body 15, and to reduce adverse effects on the wearer caused by the environment.

In addition, since the dot area ratio of the ink is 60% or more, the ink can further reduce the amount of ultraviolet rays reaching the skin of the wearer. Since it is possible to make the wearer of the absorbent article 1 less likely to be affected by ultraviolet rays, adverse effects on the wearer caused by the environment can be reduced. In addition, since the heat shielding effect of the protective layer 80 can be further enhanced, adverse effects on the wearer caused by the environment can be reduced.

(4.3) Modification 3
Next, modification 3 will be described. In Modification 3, as shown in FIG. 7A, the protective layer 80 is composed of a film 81 and an ink layer 85 . The film 81 may be arranged on the non-skin surface side T2 from the waist elastic member WE.

An ink layer 85 composed of a plurality of layers may be provided by applying ink to the film 81 a plurality of times (so-called overcoating). The ink layer 85 has a first ink layer 851 applied to the non-skin side T2 of the film 81 and a second ink layer 852 applied to the non-skin side T2 of the first ink layer 851. good. The first ink layer 851 may be deposited by a first application and the second ink layer 852 may be deposited by a second application. For example, it is possible to determine whether or not the ink layer 85 is composed of a plurality of layers by checking that the colors of the inks in the layers constituting the ink layer 85 are different from each other.

The ink may contain a material that blocks ultraviolet light. Materials that shield ultraviolet rays include, for example, ultraviolet scattering agents (such as titanium oxide and zinc oxide), ultraviolet absorbers (such as ethylhexyl acid, t-butylmethoxybenzoylmethane, oxybenzone-3, terephthalylidene dicamphorsulfonic acid etc.).

As shown in FIG. 7A, the film 81 may have a design area DR on which a design is applied. Specifically, the first ink layer 851 may constitute the design region DR. In this case, the second ink layer 852 may be a transparent ink containing a material that blocks ultraviolet rays. Thereby, the visibility of the design is not hindered by the second ink layer 852, and deterioration of the visibility of the design can be prevented.

As described above, since the film 81 having the design area DR is arranged on the non-skin surface side T2 relative to the waist elastic member WE, the visibility of the design is not hindered by the waist elastic member WE. This can prevent deterioration of the visibility of the design.

In addition, since the ink contains a material that shields ultraviolet rays, the ultraviolet shielding effect can be improved by the material that shields ultraviolet rays, in addition to the shielding properties of the ink itself. Therefore, it is possible to make the wearer of the absorbent article 1 less likely to be affected by ultraviolet rays.

Next, Modification 4 will be described. In Modification 4, ink may be placed on the outer sheet OS, as shown in FIG. 7B. That is, the ink layer 85 may be placed on the outer sheet OS. The ink layer 85 may be placed on the non-skin side T2 of the outer sheet OS (see FIG. 7B), or may be placed on the skin side T1 of the outer sheet OS.

Further, the ink layer 85 may be arranged on the folded portion OSa of the outer sheet OS. Therefore, the ink layer 85 may have a folded portion 85b.

As described above, since the protective layer 80 is composed of the ink arranged on the outer sheet OS, the rigidity of the protective region PR does not increase, and the comfort of the absorbent article 1 can be maintained.

(5) Evaluation Next, the measurement results of the ultraviolet shielding rate and the measurement results of the heat shielding properties will be described.

(5.1) Ultraviolet Shielding Rate Using the absorbent articles according to Examples 1 to 11 and Comparative Example 1 shown below, the ultraviolet ray shielding rate was measured by the measurement method described above. The ultraviolet shielding rate was measured for each of the protective layer 80 alone and the absorbent article 1 .

In Example 1, the protective layer 80 is the film 81 . In Example 1, the film 81 is not coated with ink.

In Examples 2 to 7, the protective layer 80 is a film 81 on which white ink is applied. In Example 2, the halftone dot area ratio of the ink was 50%, in Example 3, the halftone dot area ratio of the ink was 60%, and in Example 4, the halftone dot area ratio of the ink was 70%. In Example 5, the halftone dot area ratio of the ink is 80%, in Example 6, the halftone dot area ratio of the ink is 90%, and in Example 7, the halftone dot area ratio of the ink is 100%. be.

In Examples 8 and 9, the protective layer 80 is a film 81 having an ink containing an ultraviolet absorbing material disposed thereon. In Example 8, the halftone dot area ratio of the ink is 50%, and in Example 9, the halftone dot area ratio of the ink is 100%.

In Example 10, the protective layer 80 is a film 81 on which black ink is applied. In Example 2, the halftone dot area ratio of the ink is 100%.

In Example 11, the protective layer 80 is a white ink layer 85 . White ink is placed on the non-woven fabric sheet.

It should be noted that either gravure printing or flexographic printing was used as the method of disposing the ink in the above examples.

Comparative Example 1 is a normal absorbent article in which the protective layer 80 is not provided.

The measurement results are shown below.

As shown in Table 1, it was found that each example in which the protective layer 80 was provided increased the UV shielding rate by 50% or more compared to Comparative Example 1.

The average Japanese person's skin becomes red when exposed to ultraviolet rays of 300 J/m ² or more. Since the UC index during the daytime (9:00 to 14:00) in summer is 8 on average, the amount of ultraviolet rays reaches 300 J/m ² in 25 minutes when the skin is exposed. Here, the intensity of ultraviolet rays at a water depth of 50 cm is 40% of that at the ground surface. Here, in the pool for infants, the water depth is 20 to 30 cm. Assuming that the intensity of UV rays at a water depth of 20 to 30 cm is 70% of the ground surface, the portion covered with an absorbent article with a UV shielding rate of 60% has an UV dose of 300J. /m ² , it takes 89 minutes. Since 70% of infants spend less than 1.5 hours playing in the water, if they are wearing absorbent articles with a UV shielding rate of 60%, before the amount of UV rays reaches about 300 J/m ² , You can finish your water play time. Therefore, since there are many cases where only the absorbent article is worn while playing in the water, the absorbent article 1 according to the embodiment is effectively used as the absorbent article 1 for playing in the water. It is expected that the effect will be obtained.

It should be noted that 90% of infants are able to finish playing in the water before the amount of ultraviolet rays reaches approximately 300 J/m ² if they wear absorbent articles with an ultraviolet shielding rate of 80%. All infants can finish water play time before UV dose reaches about 300 J/m ² if they are wearing absorbent articles with 80% shielding rate.

(5.2) Thermal Insulation Next, measurement of thermal insulation will be described with reference to FIG. FIG. 8 is a diagram for explaining the measurement of heat shielding.

Using the absorbent articles according to Example 7 and Comparative Example 2, the ultraviolet shielding rate was measured. Comparative Example 2 is a normal absorbent article in which the protective layer 80 is not provided.

As shown in FIG. 8A, the measurement sample SP is placed on one of the test strip holding frames 210 installed on the sample stage 200 . Nothing is placed on the other test piece holding frame 210 . The height h of the specimen holding frame 210 is approximately 5 mm. The measurement sample SP was heated by illuminating the measurement sample SP from above with a reflector lamp 220 . The temperature change of the heat source photoreceptor 230 (specifically, black drawing paper) placed under the measurement sample SP was measured over time using the thermo camera 240 .

As shown in FIG. 8B, in Comparative Example 2, the temperature of the heat source photoreceptor 230 exceeded 65 degrees 15 minutes after the start of measurement. On the other hand, in Example 7, the temperature of the heat source photoreceptor 230 only rose to 55 degrees even after 15 minutes from the start of measurement.

From the above, it was found that the absorbent article 1 according to Example 7 had a heat shielding effect.

(5) Other Embodiments Although the present invention has been described in detail using the above-described embodiments, it should be understood by those skilled in the art that the present invention is not limited to the embodiments described herein. is clear. The present invention can be implemented with modifications and variations without departing from the spirit and scope of the invention defined by the claims. Accordingly, the descriptions herein are for the purpose of illustration and description, and are not intended to have any limiting meaning with respect to the present invention.

In the above description, the designed film 81 may be arranged so as to encircle the waist region WR in the width direction W. This not only improves the design, but also allows the protective layer 80 to cover the entire waist region WR, thereby reducing adverse effects on the wearer due to the wearing environment. The design applied to the film 81 may be the same as the design applied to the crotch region S3. As a result, the impression that the waist region WR and the crotch region S3 are separate bodies is faded, and the waist region WR and the crotch region S3 are easily visually recognized as one, and the absorbent article 1 has an appearance like ordinary pants. It can be easily recognized visually from the outside. Further, when the design of the film 81 overlaps the elastic member (for example, the waist elastic member WE, the elastic member for leg gathers, etc.) in the thickness direction T from the non-skin side T2, the elastic member can be made difficult to see. . Thereby, the appearance of the absorbent article 1 can be easily visually recognized as that of ordinary pants without making the viewer feel the elastic member.

In the above, the film 81 may be transparent or non-transparent. Without ink, the film 81 is preferably opaque.

In the above description, the ink may contain a material that blocks ultraviolet rays, but the present invention is not limited to this. For example, by kneading the material into the nonwoven fabric sheet, the nonwoven fabric sheet (for example, the inner sheet IS, the outer sheet OS, etc.) included in the exterior body 15 may contain the material that shields ultraviolet rays. The nonwoven sheet may contain, for example, zinc oxide. The nonwoven fabric sheet may contain titanium oxide such that the weight ratio (% by weight) of titanium oxide to the raw material of the nonwoven fabric is in the range of 1.5% by weight or more and 3% by weight or less. The nonwoven fabric sheet may contain 3% by weight or more. Thereby, the nonwoven fabric sheet can have the effect of shielding ultraviolet rays without lowering the strength of the nonwoven fabric.

In Modification 4 described above, the ink layer 85 was arranged on the outer sheet OS. The ink layer 85 may have a first ink layer 851 and a second ink layer 852 . For example, the outer sheet OS, the second ink layer 852 forming the design area DR, and the first ink layer 851 may be arranged from the non-skin side T2 toward the skin side T1. Also, the film 81 may be arranged on the non-skin surface side T2 of the first ink layer 851 . The film 81 may be arranged on the non-skin surface side T2 from the waist elastic member WE. The first ink layer 851 and the second ink layer 852 may be sandwiched between the outer sheet OS and the film 81 . In this case, the first ink layer 851 and the second ink layer 852 may be applied to the skin surface of the outer sheet OS or may be applied to the non-skin surface of the film 81 .

Further, in the above description, ink (for example, white ink) may be solidly applied as the first ink layer 852 on the outer sheet OS. In addition, since the nonwoven fabric is generally white, the white ink is usually not applied solidly. Note that, unlike the film 81, when the nonwoven fabric is solidly coated, the dot area ratio of the ink may be less than 100%. That is, as described above, it is only necessary to confirm that the colors are arranged on the entire surface with the naked eye.

The absorbent article 1 described above may be accommodated in a container 100 as shown in FIG. FIG. 9 is a diagram for explaining the container 100. FIG. A container 100 for absorbent articles 1 may include a plurality of absorbent articles 1 and a package 101 that accommodates the plurality of absorbent articles 1 . As shown in FIG. 9A, the package 101 may be provided with an indicator 110 indicating that the absorbent article 1 has a function of blocking ultraviolet rays. The display unit 110 may display, for example, “UV CUT”, “UV CUT rate XX%”, and the like. As a result, the user can visually recognize that the absorbent article 1 has a function of blocking ultraviolet rays before opening the container 100, so that the user can feel secure.

In addition, as shown in FIG. 9B, the package 101 may be provided with an indicator 110 indicating that the absorbent article 1 has a heat shielding function. The display unit 110 may display "Heat Shield", "Heat Shielding Effect", and "Feel -5 degrees". As a result, the user can visually recognize that the absorbent article 1 has a heat-shielding function before opening the container 100, thereby providing the user with a sense of security.

The containing body 100 may contain a plurality of absorbent articles 1 in one containing space. Further, the container 100 may have a package 101 in which each absorbent article 1 is accommodated in an individual accommodation space (accommodation portion) and a plurality of accommodation portions are arranged in a line. The package may be tearable one by one. A display unit 110 may be provided for each storage unit.
