An exterior member at the lower crotch connecting the rear exterior member 30 may be provided. Further, the elastic members 23 and 33 around the waist and the elastic members 15 around the legs may be sheet-shaped elastic members (stretchable film or stretchable non-woven fabric) instead of thread rubber.

=== First Embodiment: Repellent Placement Region 41 ===
4 and 5 are explanatory views of the repellent arrangement region 41, and is a diagram showing the anterior trunk peripheral portion 1F in the stretched state.

The diaper 1 is provided with an "insect repellent 40". The insect repellent 40 is a repellent (insect repellent) against pests such as mosquitoes, silkworms, chironomids, and flies, and is a synthetic compound or a natural plant extract containing a component having an insect repellent effect. For example, citronellal, 1,8-cineole, linaryl acetate, DEET (N, N-diethyl-3-methylbenzamide), sesquitelpen, ethyl ethylbutylacetylaminopropionate, picaridin, pyrethroid, cinnamon, rosemary, lavender, peppermint. , Eucalyptus, citronellal, lemon eucalyptus, vine and the like can be used. The repellent 40 can be selected according to the target pest and the person to be worn. In this embodiment, an isolated fragrance extracted from lemongrass was adopted. As a result, a component having an insect repellent effect (citronellal) is imparted to the diaper 1.

The repellent 40 is preferably an allergen-free substance. For example, the EU (European Union) Cosmetics Directive (76/768 / EEC) does not substantially contain the 26 substances that are required to be labeled as allergen substances (the ratio in the repellent 40 is 1% or less) is preferable. Further, it is preferable that the repellent 40 does not impair the adhesive performance of the hot melt adhesive used for the diaper 1.

The repellent 40 of the present embodiment is contained in microcapsules (membrane material). Microcapsules are capsules having a diameter of 1 to 1000 μm and having a space containing a core material (repellent 40). Examples of the material of the microcapsules include urethane resin, gelatin, gelatin / Arabic rubber, melamine resin, urea, formalin resin, saccharides and the like. In this embodiment, microcapsules made of urethane resin that disintegrate due to physical impact are adopted. However, the microcapsules are repellents contained in the microcapsules because the membrane material collapses due to physical stimuli (eg, pressure, shock, heat, vibration, light, etc.) or chemical stimuli (eg, contact with liquid). As long as 40 is released, there is no particular limitation.

Since the repellent 40 is contained in the microcapsules, many repellents 40 are retained in the diaper 1 until the diaper 1 is worn. Then, when the diaper 1 is worn, the diaper 1 is rubbed by the movement of the wearer, or the user rubs or grabs the area where the repellent 40 is provided, and the microcapsules generate physical irritation. It breaks and the repellent 40 is released to the outside of the diaper 1. However, the repellent 40 does not have to be contained in microcapsules.

Examples of the method of providing the repellent 40 on the diaper 1 include a method of applying a liquid in which microcapsules containing the repellent 40 are dispersed to the diaper 1. The liquid (dispersion medium) that disperses the microcapsules is preferably one that does not dissolve or swell the microcapsules and retains the function of the repellent 40. Examples of the coating method include various known methods such as a spraying method, a roller coating method, and a brush coating method. Further, as another method of providing the repellent 40 on the diaper 1, for example, the material constituting the diaper 1 is immersed in a dispersion (solution) of the repellent 40, or the repellent is applied to the fibers of the material constituting the diaper 1. Examples thereof include a method of kneading the 40 and mixing the particulate repellent 40 with the fibers of the material constituting the diaper 1.

As described above, the diaper 1 is a pants-type diaper in which a pair of waist circumference portions 1F and 1B are joined by a pair of joint portions 2 on both sides in the left-right direction. As a result of diligent research, the applicant has found that the main subjects of wearing pants-type diapers (older infants with active movements such as high-high and walking) are those with legs (especially thighs and shins) rather than faces. Was found to be prone to insect bites.

Therefore, in the diaper 1, the insect repellent 40 is provided in the lower regions 1FL and 1BL of at least one of the pair of waist circumferences 1F and 1B. In the diaper 1 of the first embodiment, as shown in FIGS. 4 and 5, the repellent 40 is provided in the lower region 1FL of the anterior waist circumference 1F. That is, the repellent 40 is provided at the portion of the front exterior member 20 located in the lower region 1FL of the front trunk peripheral portion 1F and the portion of the absorbent main body 10.

By doing so, the repellent 40 is provided at the site of the diaper 1 closer to the wearer's leg, as compared with the case where the repellent 40 is provided only in the upper regions 1FU and 1BU of the waist circumference 1F and 1B, for example. Therefore, the repellent 40 is released around the wearer's leg, and insect bites on the wearer's leg can be prevented. That is, it is possible to effectively prevent insect bites of the wearer of the pants-type diaper 1 whose legs are easily bitten. In addition, infants often wear shorts in hot weather, which is prone to insect bites. Therefore, by providing the repellent 40 in the lower regions 1FL and 1BL of the waist circumference 1F and 1B, the repellent 40 is easily released to the outside from the opening of the leg of the clothes, and the insect repellent effect can be enhanced. In addition, infants may wear clothes such as rompers that are connected up and down. Also in this case, by providing the repellent 40 in the lower regions 1FL and 1BL of the waist circumference 1F and 1B, the repellent 40 is difficult to stay inside the clothes and is easily released to the outside from the opening of the legs of the clothes.

Specifically, as shown in FIG. 3, a repellent 40 is provided on the non-skin side surface of the non-skin side sheet 22, which is a portion of the front exterior member 20 located in the lower region 1FL of the front waist circumference 1F. Is (painted). As described above, by providing the repellent 40 on the non-skin side portion of the diaper 1, the repellent 40 is easily released to the outside of the diaper 1 and the insect repellent effect can be enhanced.

However, the present invention is not limited to the above, and the repellent 40 may be provided in another portion located in the lower region 1FL of the anterior waist circumference portion 1F. For example, the repellent 40 may be provided on the skin side surface of the non-skin side sheet 22 of the front exterior member 20, the skin side sheet 21, or the print sheet 24. Further, the repellent 40 may be provided on the absorbent core 12 of the absorbent main body 10, the back sheet 13, and the exterior sheet 14. Further, the number of materials provided with the repellent 40 is not limited to one, and may be plural.

Further, at least a part of the repellent 40 may be provided in the lower regions 1FL and 1BL of the waist circumference portions 1F and 1B, and the repellent 40 may be provided in the upper regions 1FU and 1BU. However, in the waist circumference portion (here, the front side waist circumference portion 1F) where the repellent 40 is provided, the lower region (1FL) is larger than the basis weight (g / m ² ) of the repellent 40 in the upper region (1FU). It is preferable that the basis weight (g / m ² ) of the repellent 40 in the above is higher. That is, the value obtained by dividing the total weight (g) of the repellent 40 provided in the upper region (1FU) by the area (m ² ) of the upper region (1FU) in the stretched state is the lower region (1FL). It is preferable that the total weight (g) of the repellent 40 provided in the above is larger than the value obtained by dividing by the area (m ² ) of the lower region (1FL) in the stretched state.

By doing so, more repellents 40 are provided at the site of the diaper 1 near the wearer's legs, so that the repellents 40 are more likely to be released around the wearer's legs. Therefore, it is possible to more effectively prevent insect bites of the wearer of the pants-type diaper 1 whose legs are easily bitten.

It should be noted that confirmation that the repellent 40 is provided in the lower regions 1FL and 1BL of the waist circumference 1F and 1B can be performed by a well-known method. First, the waist circumferences 1F and 1B (absorbent main body 10 + exterior members 20 and 30) to be measured are cut out from the diaper 1, and the cut out waist circumferences 1F and 1B are further divided into upper and lower parts, and the lower regions 1FL and 1BL are further divided. To form a sample of. By component analysis of the sample using, for example, a gas chromatography device (7890B manufactured by Agilent or an equivalent device), the sample of the lower regions 1FL and 1BL has a component having an insect repellent effect (repellent 40). Can be confirmed whether or not it contains. In addition, when the repellent 40 is contained in the microcapsules, the presence or absence of the microcapsules (repellent 40) can be confirmed by observing the samples of the lower regions 1FL and 1BL with an electron microscope.

Further, the comparison between the basis weight (g / m ² ) of the repellent agent 40 in the upper regions 1FU and 1BU and the basis weight (g / m ² ) of the repellent agent 40 in the lower regions 1FL and 1BU can also be compared by using the above gas chromatography apparatus. Can be done using.
(1) First, the waist circumferences 1F and 1B (absorbent body 10 + exterior members 20 and 30) to be measured are cut out from the diaper 1 and separated into lower regions 1FL and 1BL and upper regions 1FU and 1BU. The separated lower regions 1FL and 1BL and the upper regions 1FU and 1BU are further cut into fine samples of a predetermined size (for example, vertical direction × horizontal direction = 20 mm × 40 mm, etc.).
(2) Next, the microcapsules are dissolved by immersing the finely cut sample in water, and the sample is a mixture of the repellent 40 (ingredient having an insect repellent effect) and other ingredients (solvent, etc.). To extract.
(3) The mixture extracted for each sample is component-analyzed using a gas chromatography device. Then, for each sample, the peak value of the repellent 40 (component having an insect repellent effect) and the peak value of other components (solvent, etc.) are obtained, and the peak value of the repellent with respect to the peak value of the other components. (Peak value of repellent / peak value of other components) is calculated. It is assumed that the ratio corresponds to the amount of the repellent 40 provided in the sample.
(4) Finally, the average value of the ratio of the repellents (peak value of the repellent / peak value of other components ≒ amount of the repellent 40) of the plurality of samples constituting the upper regions 1FU and 1BU is calculated. It shall correspond to the basis weight of the repellent 40 in the upper regions 1FU and 1BU. Further, the average value of the ratio of the repellents (peak value of the repellent / peak value of other components ≒ amount of the repellent 40) of a plurality of samples constituting the lower regions 1FL and 1BL is calculated, and the lower region 1FL, The comparison is made assuming that it corresponds to the basis weight of the repellent 40 in 1BL.
Further, the basis weight of the repellent 40 in the front waist circumference portion 1F and the basis weight of the repellent 40 in the posterior trunk circumference portion 1B, which will be described later, can be compared in the same manner.

Here, in the diaper 1, the region where the repellent agent 40 is provided is also referred to as a “repellent agent placement region 41”. The repellent placement region 41 in the diaper 1 can also be specified by the same method as described above. That is, it is preferable to specify the repellent arrangement region 41 by cutting the diaper 1 into small samples, analyzing the components of each sample using a gas chromatography device, and confirming whether or not the diaper 40 has the repellent 40. Further, the finely cut sample may be observed with an electron microscope to confirm the presence or absence of microcapsules (repellent 40), and the repellent placement region 41 may be specified.

In the diaper 1 of the first embodiment, as shown in FIG. 5, the repellent placement region is longer in the left-right direction than the up-down direction of the diaper 1 and continuously extends in the left-right direction from the left end to the right end of the front waist circumference portion 1F. Three 41s are provided side by side with an interval in the vertical direction.

Therefore, in the diaper 1, at least a part of the repellent 40 is provided in the region where the absorbent core 12 is located in the waist circumference 1F and 1B (here, the front waist circumference 1F) where the repellent 40 is provided. Has been done. That is, in the unfolded state of the diaper 1, at least a part of the absorbent core 12 and the repellent placement region 41 overlap each other in the thickness direction of the diaper 1.

In this case, the repellent 40 provided at a position overlapping the absorbent core 12 (particularly, the repellent 40 provided on the non-skin side of the absorbent core 12) passes through the dense and thick absorbent core 12. It's difficult to do. Therefore, the repellent 40 is more likely to be released to the outside of the diaper 1 than to the skin side. Therefore, the insect repellent effect of diaper 1 is enhanced.

Further, the front exterior member 20 and the rear exterior member 30 have the waist circumference elastic members 23 and 33 in the waist circumference portions 1F and 1B. Each of the waist circumference portions 1F and 1B has a non-stretchable region NS in which the waist circumference elastic members 23 and 33 cannot expand and contract in the region where the absorbent main body 10 is located. By doing so, the absorbent body 10 (absorbent core 12) contracts due to the elastic members 23 and 33 around the waist, and the absorbent body 10 (absorbent core 12) contracts.
It is possible to prevent a gap from being created between the diaper 1 and the wearer. Although the drawings show only the parts of the waistline elastic members 23 and 33 that exhibit elasticity, there are parts of the waistline elastic members 23 and 33 that do not exhibit elasticity in the non-stretchable region NS. You may.

Then, it is preferable that at least a part of the repellent 40 is provided in the non-stretchable region NS of the waist circumference 1F, 1B (here, the front waist circumference 1F) where the repellent 40 is provided. By doing so, it is possible to prevent the repellent 40 from being covered with the wrinkles generated in the waist circumference portions 20 and 30 by the waist circumference elastic members 23 and 33, and the repellent agent 40 is easily released to the outside of the diaper 1. Therefore, the insect repellent effect of diaper 1 is enhanced. However, the present invention is not limited to this, and the repellent 40 may not be provided in the non-stretchable region NS.

When the repellent 40 is encapsulated in a plurality of microcapsules, as shown in FIGS. 1 and 4, the waist circumference 1F and 1B (here, the front waist circumference 1F) provided with the repellent 40 are provided. May have a marker 50 indicating the area where the repellent 40 is provided. By doing so, the area where the repellent 40 is provided is easily and correctly recognized by the user.

The mark portion 50 of the present embodiment is formed by printing in a color (for example, green, yellow, etc.) different from the surrounding color (for example, white). Specifically, the mark portion 50 printed on the print sheet 24 is visible from the outside of the diaper 1 via the non-skin side sheet 22. Further, the mark portion 50 shown in FIG. 4 has a character “AntiMos” indicating that the diaper 1 has an insect (mosquito) repellent effect and a character “Rub” indicating an operation for destroying microcapsules.
have "here". Therefore, the user who visually recognizes the mark portion 50 can break the microcapsules when wearing the diaper 1 or at a desired timing during wearing, and can release a larger amount of the repellent 40.

However, the mark portion 50 is not limited to the one illustrated in FIG. 4, and may be, for example, a pattern or a plain colored region. Further, the material for printing the mark portion 50 is not limited to the print sheet 24, and printing may be performed on other materials (nonwoven fabric or the like) constituting the diaper 1. Further, the mark portion 50 may be formed by the squeezed portion (unevenness) obtained by squeezing the diaper 1 in the thickness direction, the elastic members 23 and 33 around the waist may be colored, or the microcapsules (the repellent 40 itself) may be colored. As a result, a marker portion 50 having a color different from that of the surroundings may be formed.

Then, on the same side in the front-rear direction, the non-stretchable region NS of the waist circumference portions 1F and 1B and the mark portion 50 overlap in the front-rear direction, and at least a part of the repellent 40 is provided in the overlapping region. Is preferable. That is, in the unfolded state of the diaper 1, at least a part of the non-stretchable region NS, the mark portion 50, and the repellent placement region 41 may overlap each other in the thickness direction of the diaper 1.

By doing so, the mark portion 50 is located in the non-stretchable region NS where there are few wrinkles due to the elastic members 23 and 33 around the waist, so that the visibility of the mark portion 50 is improved. Further, since the absorbent main body 10 (non-stretchable region NS) and the repellent placement region 41 overlap each other, the highly rigid absorbent core 12 serves as a pedestal, and the user can easily rub the repellent placement region 41. Therefore, the microcapsules are efficiently broken, and the repellent 40 is easily released to the outside of the diaper 1. However, the present invention is not limited to this, and the mark portion 50 and the repellent 40 may not be provided in the non-stretchable region NS.

Further, as shown in FIG. 5, a plurality of repellent agent placement regions 41 are provided side by side in the front waist circumference portion 1F at intervals in the vertical direction of the diaper 1. In this case, since the repellent 40 is not concentrated on a part of the diaper 1, the repellent 40 can be provided over a wide range in the vertical direction of the diaper 1 while suppressing the amount of the repellent 40 provided on the diaper 1. .. Therefore, the insect repellent effect occurs in a wide range in the vertical direction of the diaper 1. However, the present invention is not limited to this, and the repellent arrangement region 41 may be provided without a gap in the vertical direction.

In the present embodiment, the width (length in the vertical direction) of one repellent placement region 41 is set to about 5 mm, and the vertical distance between the repellent placement regions 41 is set to 2.5 mm. Therefore, the repellent 40 is provided in the region where the length in the vertical direction is about 20 mm. That is, since the repellent 40 is provided in the area about the length of the fingertip of the user, the user can easily rub the repellent arrangement area 41 with the pad of the finger.

Further, by arranging the plurality of repellent placement regions 41 at intervals, it becomes easy to adjust the number of microcapsules to be broken, that is, the amount of the repellent 40 released, according to the size of the region rubbed by the user. In the mark portion 50 (FIG. 1) of the present embodiment, the region between the repellent placement regions 41 is also colored in the same manner as the repellent placement region 41. However, the mark portion 50 may also have colored regions spaced in the vertical direction in accordance with the repellent arrangement region 41. By doing so, the user can rub three colored areas (repellent placement area 41) when he / she wants to enhance the insect repellent effect, and one colored area when he / she wants to obtain an appropriate insect repellent effect. (Repellent arrangement region 41) can be rubbed, and it becomes easy to adjust the release amount of the repellent 40.

Further, the repellent arrangement region 41 of the first embodiment is located in the lower region 1FL of the front waist circumference portion 1F from a position where it overlaps the left joint portion 2 in the front-rear direction (thickness direction), and is front-to-back with the right joint portion 2. It is continuously provided in the left-right direction up to a position where it overlaps in the direction. Therefore, the repellent 40 is provided at the site of the diaper 1 near each of the pair of leg openings LH, and the repellent 40 is easily released near both legs of the wearer. Further, the repellent arrangement region 41 can overlap with the absorbent body 10 and the absorbent core 12. Further, since the repellent 40 is provided on the pair of joints 2, the repellent 40 is provided near the apex of the leg opening LH of the diaper 1, that is, the portion where the legs are most exposed. , Can prevent insect bites on the wearer's legs more effectively.

Further, in the manufacturing process of the diaper 1, a pair of joint portions 2 can be formed after the repellent 40 is applied to the front waist circumference portion 1F. In this case, when the joint portion 2 is formed by welding or the like, the microcapsules located at the formed portion of the joint portion 2 can be destroyed. Therefore, the diaper 1 can be enclosed in a package (bag for packaging) in a state where a part of the microcapsules provided in the diaper 1 is destroyed. Therefore, the repellent 40 is filled in the package, and the effect of the repellent 40 is easily imparted to the entire diaper 1. In addition, the user who opened the package can feel the repellent 40 and can recognize that the diaper 1 has an insect repellent effect. Regarding the fact that the microcapsules located at the joint portion 2 were destroyed in the manufacturing process, it is advisable to check the diaper 1 immediately after being taken out from the package with an electron microscope. That is, it can be confirmed that the number of broken microcapsules located at the joint portion 2 is larger than the number of broken microcapsules located at a portion other than the joint portion 2.

Further, in the diaper 1 of the first embodiment, the repellent agent 40 is provided on the front side waist circumference portion 1F, and the repellent agent 40 is not provided on the posterior side waist circumference portion 1B. In addition, the diaper 1 for infants is often enclosed in a package without being folded. Therefore, it is preferable to arrange a plurality of diapers 1 in the thickness direction and enclose them in the package so that the front side waist circumference portion 1F of one diaper 1 and the rear side waist circumference portion 1B of another diaper 1 come into contact with each other. By doing so, the effect of the repellent 40 provided on the front side waist circumference portion 1F of one diaper 1 can be easily applied to the rear side waist circumference portion 1B of another diaper 1. Therefore, the insect repellent effect is likely to occur also in the rear waist circumference portion 1B of the diaper 1.

Further, in the lower regions 1FL and 1BL of the waist circumference portions 1F and 1B, the region provided with the repellent 40 is larger than the lower end (1Fa) of the waist circumference portions 1F and 1B (here, the front waist circumference portion 1F). It is preferably located at a distance from the upper side. By doing so, even when the lower ends of the waist circumferences 1F and 1B are turned over by the movement of the wearer's legs when the diaper 1 is worn, it is difficult for the repellent placement area 41 to be covered by the turned-up portion. Therefore, the repellent 40 is more easily released to the outside, and an insect repellent effect is produced. However, the present invention is not limited to this, and the repellent 40 may be provided up to the lower ends of the waist circumference portions 1F and 1B.

Further, the waist circumference portions 1F and 1B have a stretchable region (a region excluding the non-stretchable region NS) that can be expanded and contracted by the waist circumference elastic members 23 and 33. In the waist circumference 1F and 1B (here, the front waist circumference 1F) provided with the repellent 40, the stretchable region in the lower regions 1FL and 1BL is higher and lower than the stretchable region in the upper regions 1FU and 1BU. It is preferable that the force for extending the region of the unit length in the direction to a predetermined length in the left-right direction is high.

That is, it is preferable that the tensile stress of the lower regions 1FL and 1BL in which the repellent 40 is provided is high, and wrinkles are likely to occur in the lower regions 1FL and 1BL due to the elastic members around the waist 23 and 33. By doing so, in the natural state in which the elastic members 23 and 33 around the waist are not stretched, that is, in the unused state of the diaper 1, the repellent arrangement region 41 is likely to be covered with the wrinkles generated in the waist circumference portions 1F and 1B. .. Therefore, the repellent 40 is unlikely to be released before the use of the diaper 1, and the repellent 40 is easily held by the diaper 1 until the diaper 1 is worn.

However, contrary to the above, the expansion / contraction region in the lower regions 1FL and 1BL extends a predetermined length in the left-right direction in the region of unit length in the vertical direction as compared with the expansion / contraction region in the upper regions 1FU and 1BU. The force for causing the force (stretching stress) may be low. That is, wrinkles may be less likely to occur in the lower regions 1FL and 1BL where the repellent 40 is provided. By doing so, the repellent arrangement region 41 is less likely to be covered with wrinkles and is exposed to the outside while the diaper 1 is being worn, so that the repellent 40 is easily released to the outside.

Further, the expansion / contraction region of one of the pair of waist circumferences 1F and 1B has a predetermined unit length region in the vertical direction in the left-right direction as compared with the expansion / contraction region of the other waist circumference. It is assumed that the force (extension stress) for extending the length of is high. In that case, the basis weight of the repellent 40 in one waist circumference (here, the front waist circumference 1F) is larger than the basis weight of the repellent 40 in the other waist circumference (here, the posterior waist circumference 1B). It should be high.

That is, it is preferable to place more repellent 40 around the waistline where the tensile stress is higher. By doing so, in the state before the use of the diaper 1, the area provided with the more repellent 40 is likely to be covered with wrinkles, and the repellent 40 is less likely to be released. Therefore, more repellent 40 is likely to be retained in the diaper 1 until the diaper 1 is worn.

However, contrary to the above, the basis weight of the repellent 40 in one of the pair of waist circumferences 1F and 1B having a high tensile stress (here, the posterior waist circumference 1B) is set to the other waist circumference. It may be lower than the basis weight of the repellent 40 in the portion (here, the front waist circumference portion 1F). By doing so, while wearing the diaper 1, the area provided with the more repellent 40 is less likely to be covered with wrinkles and is exposed to the outside, so that more repellent 40 is more likely to be released.

In order to adjust the tensile stress of the waist circumference 1F and 1B, the number of waist circumference elastic members 23 and 33, the thickness of the thread-like waist circumference elastic members 23 and 33, and the waist circumference elastic members 23 and 33 are seated. It is advisable to adjust the stretch ratio when fixing to.

Further, the stretching stress of the upper regions 1FU and 1BU and the stretching stress of the lower regions 1FL and 1BL can be compared by the following method using a tensile tester.
(1) First, the absorbent main body 10 and the exterior members 20 and 30 are separated by using a cold spray or the like, and the waist circumference portions 1F and 1B to be measured are taken out from the exterior members 20 and 30. The taken-out waist circumference 1F, 1B (exterior members 20, 30) is divided into upper and lower parts, and the upper region 1FU, 1BU is divided into upper and lower parts.
And a sample of the lower regions 1FL and 1BL are prepared.
When the waist circumference portions 1F and 1B have the non-stretchable region NS, the non-stretchable region NS is removed from the sample, and the sample is separated into a plurality of pieces so as to have a rectangular shape. For example, in the case of FIG. 5, the sample of the upper region 1FU is separated into three samples, a region above the non-stretchable region NS, and a region on the left side and a region on the right side of the non-stretchable region NS. Further, the sample of the lower region 1BU is separated into two samples, a region on the left side and a region on the right side of the non-stretchable region NS.
(2) Next, for each sample, both ends of the sample corresponding to the left-right direction of the diaper 1 are gripped by the chuck of the tensile tester. The inter-chuck distance is adjusted so that the sample does not loosen and is not stretched. Then, the distance between the chucks is widened at a predetermined speed by a tensile tester, and the load when the sample is stretched by a predetermined length in the left-right direction is acquired.
(3) Next, the length of each sample in the vertical direction is measured. Then, the load (N) acquired in (2) is converted into a value (N / mm) per unit width (mm) in the vertical direction, and the extension stress of the upper regions 1FU and 1BU and the lower regions 1FL and 1BL are obtained. Let it be the tensile stress of.
When the samples of the upper region 1FU and 1BU and the samples of the lower region 1FL and 1BL are separated in order to exclude the non-stretchable region NS, the elongation stress (N / mm) for each separated sample is calculated and the average value thereof. Is the stretching stress of the upper regions 1FU and 1BU and the stretching stress of the lower regions 1FL and 1BL.

Further, the extension stress of the front waist circumference portion 1F and the extension stress of the posterior waist circumference portion 1B can also be compared by the above method using a tensile tester. It is advisable to prepare a sample without dividing the waist circumferences 1F and 1B (exterior members 20 and 30) taken out from the diaper 1 into upper and lower parts.

=== Modification example of the first embodiment ===
6A and 6B are explanatory views of the repellent placement region 41 of the modified example of the first embodiment. For example, as shown in FIG. 6A, the repellent 40 may be provided in both the lower region 1FL of the front waist circumference 1F and the lower region 1BL of the rear waist circumference 1B, and the anterior and posterior sides may be provided. The area (coating pattern) in which the repellent 40 is provided may be different. Further, as shown in FIG. 6B, the repellent 40 is provided in the lower region 1BL of the posterior trunk circumference 1B, and the repellent 40 is provided in the lower region 1FL of the front trunk circumference 1F and the entire front trunk circumference 1F. It does not have to be provided. Further, although not shown, if the repellent 40 is provided in at least one of the lower regions 1FL and 1BL of the pair of waist circumference portions 1B and 1F, the repellent agent is provided in the upper regions 1FU and 1BU in the other waist circumference portion. 40 may be provided. Further, although not shown, the repellent placement region 41 of the lower regions 1FL and 1BL of the waist circumference portions 1F and 1B may continuously extend in the vertical direction to the upper regions 1FU and 1BU and the lower extension portion 34. ..

Further, in the diaper 1 illustrated in FIGS. 4 and 5, the repellent arrangement region 41 is continuously provided in the left-right direction, but the pattern (coating pattern) of the repellent arrangement region 41 is not limited to this. For example, as shown in FIG. 6A, a plurality of regions where the repellent 40 is provided may be provided side by side at intervals in the left-right direction. In this case, the repellent 40 can be provided in a wide range in the left-right direction of the diaper 1 while suppressing the amount of the repellent 40 provided in the diaper 1. Therefore, the insect repellent effect occurs in a wide range in the left-right direction of the diaper 1.

Further, when the repellent arrangement region 41 is separated in the left-right direction as shown on the front side of FIG. 6A, it becomes easy to adjust the release position of the repellent 40. For example, when it is desired to enhance the insect repellent effect of one of the left and right legs of the wearer, the user can rub the repellent placement area 41 near the one leg. Further, as shown on the rear side of FIG. 6A, when a plurality of repellent placement regions 41 are arranged at narrow intervals in the left-right direction, the size of the region rubbed by the user (the number of repellent placement regions 41). It becomes easy to adjust, and it becomes easy to adjust the release amount of the repellent 40.

Further, as shown in FIG. 6A, the repellent 40 may be provided in the region of the waist circumference 1F, 1B where the repellent 40 is provided, in which the absorbent core 12 is not located. That is, in the unfolded state of the diaper 1, the absorbent core 12 and the repellent placement region 41 may not overlap in the thickness direction of the diaper 1. By doing so, it is possible to prevent the odor of the excrement absorbed by the absorbent core 12 from being mixed with the repellent 40, reducing the effect of the repellent 40 and causing an unpleasant odor.

Further, as shown in FIG. 6A, the left end 40a of the region where the repellent 40 is provided is located on the right side (inside) of the right end 2a of the left joint portion 2, and the repellent 40 is provided. The right end 40b of the region may be located on the left side (inside) of the left side end 2b of the right joint portion 2. That is, the repellent 40 may not be provided on the joint portion 2. By doing so, the joint portion 2 has high rigidity and easily protrudes while wearing the diaper 1, so that the repellent 40 provided on the joint portion 2 comes into strong contact with the wearer's clothes and the repellent 40 adheres to the clothes. It is possible to prevent it from happening.

Further, as shown in FIG. 6B, when the rear exterior member 30 has an extension portion 34 extending downward from the rear waist circumference portion 1B, the repellent 40 is also provided on the extension portion 34. May be good. By doing so, since the repellent 40 is further provided at the site of the diaper 1 near the wearer's leg, insect bites on the wearer's leg can be effectively prevented. Although not shown, the front exterior member 20 may have an extending portion extending downward from the front waist peripheral portion 1F, and the repellent 40 may be provided in the extending portion.

=== Second embodiment ===
7A, 7B, and 8 are explanatory views of the repellent placement region 41 of the second embodiment. In the diaper 1 of the second embodiment, the repellent 40 is provided on at least a part of the peripheral portion along the leg peripheral opening 1L. By doing so, the repellent 40 is provided at the site of the diaper 1 near the wearer's leg. Therefore, the repellent 40 is released around the wearer's legs, and it is possible to effectively prevent insect bites of the wearer of the pants-type diaper 1 whose legs are easily stabbed.

The diaper 1 (three-piece type, in which the repellent 40 is provided in the lower region 1FU of the front waist circumference 1F without the extension portion) illustrated in FIGS. 4 and 5 is also the leg circumference opening 1L. A repellent 40 is provided on a part of the peripheral portion along the above. That is, some of the diapers 1 of the first embodiment are included in the diaper 1 of the second embodiment.

Further, as shown in FIG. 7A, at least one of the pair of waist circumference portions 1F and 1B, the lower region 1FL and 1BL (here, the lower region 1FL of the front side waist circumference portion 1F) and the side portion of the absorbent body 10 The diaper 1 provided with the repellent 40 may be used. That is, in the diaper 1 of the first embodiment, the repellent 40 may be provided on the side portion of the absorbent body 10. In this case, since the repellent 40 is provided in a wider range of the peripheral portion along the leg circumference opening 1L, it is possible to more effectively prevent insect bites on the wearer's legs.

Further, as shown in FIG. 7B, the repellent 40 may be provided on the side of the absorbent main body 10 without providing the repellent 40 in the lower regions 1FL and 1BL of the waist circumference 1F and 1B. .. Also in this case, the repellent 40 is provided on a part of the peripheral portion along the leg peripheral opening 1L.

Further, as shown in FIG. 8, in a two-piece type diaper 1 formed of one exterior member continuous from the front waist circumference 1F to the rear waist circumference 1B, the side end portion of the exterior member 60 is repelled. The agent 40 may be provided. Also in this case, the repellent 40 is provided on a part of the peripheral portion along the leg peripheral opening 1L.

As described above, the above-described embodiment is for facilitating the understanding of the present invention, and is not for limiting the interpretation of the present invention. It goes without saying that the present invention can be modified or improved without departing from the spirit thereof, and the present invention includes an equivalent thereof.
