In Patent Document 1, there is no particular limitation on the shape and the arrangement position of the high tack force region and the low tack force region (paragraph 0020 of Patent Document 1). However, as a result of earnest studies, the inventor of the present application discovered that the following problems occur.

That is, when there is a high tack force region in a region where the pressure from the wearer is applied during wearing, especially while sitting, the high tack force region of the absorbent article strongly adheres to clothing such as underwear due to the pressure from the wearer. Will be done. This may cause damage to the clothes when the absorbent article is peeled off from the clothes.

On the other hand, if there is a low tack force region in a region where the pressure from the wearer is hardly applied during wearing, particularly when sitting, the force for fixing the low tack force region of the absorbent article to the clothing is not sufficient, and There is a possibility that the low tack force region of the sexual article may be displaced from the clothing during wearing.

Therefore, there is a demand for an absorbent article capable of reducing damage to clothes as much as possible while maintaining the force of fixing the clothes.

An absorbent article according to one aspect is a front-rear direction, a width direction orthogonal to the front-rear direction, an excretory opening facing area that faces a wearer's excretory opening, a backsheet that faces clothing when in use, and the backsheet. And an adhesive area having an adhesive for fixing to clothing. The adhesive area has a first adhesive area provided in a central portion in the width direction of the excretion opening facing area, and second adhesive areas arranged on both sides of the first adhesive area in the width direction. The basis weight of the adhesive in the first adhesive area is larger than the basis weight of the adhesive in the second adhesive area.

According to the absorbent article according to the above aspect, it is possible to reduce the damage to the clothes as much as possible while maintaining the force of fixing to the clothes.

FIG. 1 is a plan view of the absorbent article according to the first embodiment. FIG. 2 is a plan view of the absorbent article as seen from the side opposite to FIG. 1. FIG. 3 is a cross-sectional view of the absorbent article taken along the line 3A-3A in FIG. FIG. 4 is a plan view of the absorbent article according to the second embodiment as viewed from the side facing the clothing.

(1) Outline of Embodiments At least the following matters will be made clear by the present specification and the description of the accompanying drawings.

An absorbent article according to one aspect is a front-rear direction, a width direction orthogonal to the front-rear direction, an excretory opening facing area that faces a wearer's excretory opening, a backsheet that faces clothing when in use, and the backsheet. And a pressure-sensitive adhesive region having a pressure-sensitive adhesive that is fastened to clothes, the pressure-sensitive adhesive region having a first pressure-sensitive adhesive region provided in a central portion in the width direction of the excretion opening facing region and the width direction. And a second adhesive region arranged on both sides of the first adhesive region, wherein a basis weight of the adhesive in the first adhesive region is larger than a basis weight of the adhesive in the second adhesive region.

Since the central portion in the width direction of the excretion outlet facing area is a portion facing the gluteal cleft of the wearer, the pressure received from the wearer while sitting is relatively small. On the other hand, since the outer side portion in the width direction of the excretion opening facing area is a portion facing the wearer's buttocks, a strong pressure is applied from the wearer's buttocks during sitting.

According to this aspect, the second adhesive region is arranged in a region that receives relatively strong pressure from the buttocks of the wearer during sitting. Therefore, even if the basis weight of the pressure-sensitive adhesive in the second pressure-sensitive adhesive region is relatively small, the second pressure-sensitive adhesive region is firmly attached to clothing such as underwear by a strong pressure from the wearer.

In addition, the first adhesive region is generally arranged in a region where the pressure received from the wearer while sitting is relatively small. Here, the basis weight of the adhesive in the first adhesive area is larger than the basis weight of the adhesive in the second adhesive area. Therefore, the first adhesive region is firmly attached to clothing such as underwear even if the pressure received from the wearer is small.

In particular, since the vicinity of the central portion in the width direction of the excretory opening facing area is a portion that faces the wearer's excretory opening, for example, the vaginal opening, the wearer views the absorbent article from the excretory opening facing area. The area near the center in the width direction may not be strongly pressed toward the clothing. Even in this case, since the basis weight of the adhesive in the first adhesive area is larger than the basis weight of the adhesive in the second adhesive area, the first adhesive area can be firmly attached to the clothing.

As described above, in the absorbent article according to the present aspect, the basis weight of the pressure-sensitive adhesive disposed in the region that receives a strong pressure from the wearer, that is, the pressure-sensitive adhesive in the second pressure-sensitive region is low. This makes it possible to reduce the sound pressure level of the peeling sound when the absorbent article is peeled off from the clothing. The sound pressure level of the peeling sound is an index representing the adhesive force of the adhesive area to the clothing. Therefore, by reducing the sound pressure level of the peeling sound, the damage to the clothes can be reduced as much as possible.

As described above, the absorbent article according to the present aspect can reduce the damage to the clothes as much as possible while maintaining the force to fix the clothes.

According to a preferred aspect, the absorbent article has a first fold line located on the rear side of the excretion opening facing region, and the adhesive region is on the rear side of the first fold line in the center in the width direction. A third adhesive region provided in a portion, and a fourth adhesive region located on both sides of the third adhesive region in the width direction, the basis weight of the adhesive in the third adhesive region is the 4 It is larger than the basis weight of the adhesive in the adhesive area.

Since the central portion in the width direction of the region on the rear side of the first fold line is the portion facing the upper part of the gluteal cleft of the wearer, the pressure received from the wearer while sitting is relatively small. On the other hand, the outer side portion in the width direction of the region on the rear side of the first fold line is a portion facing the upper part of the wearer's buttocks, and thus receives a strong pressure from the wearer's buttocks during sitting.

Therefore, as in the area facing the excretion opening, even in the area on the rear side of the first folding line, the basis weight of the adhesive in the third adhesive area located in the central portion in the width direction is located in the outer portion in the width direction. By increasing the basis weight of the adhesive in the fourth adhesive area, the sound pressure level of the peeling sound can be reduced and the damage to the clothes can be reduced as much as possible while maintaining the force of fixing the clothes.

According to a preferred aspect, the third adhesive area is continuous with the first adhesive area, and the fourth adhesive area is continuous with the second adhesive area.

Here, when the adhesive region (adhesive) is provided intermittently in the front-rear direction, when peeling off the absorbent article, a part near the boundary between the intermittent part where the adhesive is not provided and the adhesive is provided. When peeled off from clothes, the sound pressure level of the peeling sound increases. According to this aspect, since the third adhesive region is continuous with the first adhesive region and the fourth adhesive region is continuous with the second adhesive region, it is possible to suppress an increase in peeling sound, and thereby damage the clothing. Can be suppressed.

According to a preferred embodiment, the absorbent article has a second fold line located on the front side of the excretion opening facing area, and the adhesive region is on the front side of the second fold line in the central portion in the width direction. A fifth adhesive region provided, and a sixth adhesive region located on both sides of the fifth adhesive region in the width direction, wherein the basis weight of the adhesive in the fifth adhesive region is the sixth adhesive region. Greater than the basis weight of the adhesive in the area.

At the center portion in the width direction of the region on the front side of the second folding line, the pressure received from the wearer during sitting is relatively small. On the other hand, the outer side portion in the width direction of the region on the front side of the second fold line is subjected to strong pressure by the wearer changing the legs while sitting.

Therefore, even in the region on the front side of the second fold line as in the area facing the excretion opening, the basis weight of the adhesive in the fifth adhesive region located in the central portion in the width direction is set to By increasing the basis weight of the adhesive in the 6-adhesive region, the sound pressure level of the peeling sound can be reduced and the damage to the clothing can be reduced as much as possible while maintaining the force of fixing to the clothing.

According to a preferred aspect, the fifth adhesive area is continuous with the first adhesive area, and the sixth adhesive area is continuous with the second adhesive area.

Thereby, when the wearer peels the absorbent article from the clothes in the front-rear direction, the force for pulling the absorbent article becomes substantially constant, and the absorbent article can be smoothly peeled off. Further, it is possible to suppress an increase in peeling sound when peeling the absorbent article, and thereby to prevent damage to clothes.

According to a preferred aspect, the absorbent article has a coating width defined by a total width of the adhesive in the adhesive region on a line along the width direction, as the front or rear side in the front-rear direction. It has a reduced coating width reduction region.

When the wearer peels the absorbent article from the clothing, the wearer often peels the absorbent article from the front side or the back side of the absorbent article. The coating width defined by the total width of the pressure-sensitive adhesive on the line along the width direction becomes smaller toward the front side or the back side, thereby reducing the pressure-sensitive adhesive force of the portion at the beginning of peeling of the absorbent article. be able to. Thereby, the absorbent article can be easily peeled off.

Also, the sound pressure level of the peeling sound generally tends to be high in the part of the absorbent article at the beginning of peeling, but the sound pressure level at the beginning of peeling can be reduced by reducing the adhesive strength of the part at the beginning of peeling. it can.

Further, when the wearer peels off the absorbent article from the clothing, considering that many wearers peel it off from the front side of the absorbent article, at least at the front end of the adhesive region, the adhesive on the line along the width direction. It is preferable that the coating area of is smaller toward the front side.

According to a preferred aspect, in the application width reduction area, the application area of the pressure-sensitive adhesive extends to the outer side in the front-rear direction toward the outer side in the width direction.

Thereby, the frontmost end or the rearmost end of the adhesive region can be positioned as outer as possible in the width direction. Therefore, it is possible to further widen the region formed by the outermost end of the adhesive region in the front-rear direction and the outermost end of the adhesive region in the width direction. Therefore, the absorbent article can be attached to the clothes more stably.

According to a preferred embodiment, the absorbent article has a first fold line located on the rear side of the excretion opening facing area and a second fold line located on the front side of the excretion opening facing area, When the coating width decreases toward the front side in the front-rear direction, the coating width lowering region is provided in front of the second folding line, and the coating width extends rearward in the front-rear direction. When the coating width decreases, the coating width reduction region is provided on the rear side of the first folding line.

If the area where the application width is reduced is also present in the area facing the excretion opening, the adhesive force for fixing the area facing the excretion opening to the clothing may be reduced. In this aspect, since the application width reduction region is provided on the rear side of the first fold line or on the front side of the second fold line, it is possible to maintain the force for fixing the excretory opening opposing region to the clothing.

According to a preferred aspect, the first adhesive region is provided within a range of 15 mm in the width direction from a centerline extending in the front-rear direction through the center of the absorbent article in the width direction.

Considering the size of the buttocks and clefts of a person, an area within 15 mm in the width direction from the center line in the excretory opening opposing area corresponds to a position that is less likely to receive pressure from the wearer. Therefore, the first adhesive region having the adhesive having a relatively large basis weight is provided within the range of 15 mm in the width direction from the center line, so that the central portion in the width direction of the excretory opening facing region is firmly held. Can be attached to clothing.

According to a preferred embodiment, the absorbent article is composed of a topsheet directed to the wearer's skin side, an absorber between the topsheet and the backsheet, and a portion where the absorber is compressed. And a pair of compressed portions extending in the front-rear direction in the excretion outlet facing area, and at least a part of the second adhesive region is located outside the pair of compressed portions in the width direction. ..

The area opposite the excretory mouth is sandwiched between the wearer's legs. As a result, the central portion of the area facing the excretory opening in the width direction is deformed so as to rise toward the gluteal cleft of the wearer with the compressed portion as the base point. As a result, the central portion of the area facing the excretion opening in the width direction can be brought into close contact with the wearer's skin.

In this aspect, at least a part of the second adhesive region is located outside the region between the pair of compressed parts, that is, outside the region that rises toward the gluteal cleft of the wearer with the compressed part as a base point. This area is an area that receives a strong force from the buttocks of the wearer. Therefore, at least a part of the second adhesive region having the adhesive having a relatively small basis weight is located outside the pair of squeezing portions, so that the sound pressure level of the peeling sound is reduced and damage to clothes is prevented. It can be reduced as much as possible.

According to a preferred aspect, the absorbent article has an absorber provided on the skin side of the back sheet at least in the discharge port facing area, and the absorber has the width in the discharge port facing area.

As a result, at least a part of the second adhesive region 52 is located outside the region that rises toward the gluteal cleft of the wearer with the squeezing portion 36 as a base point. This area is an area that receives a strong force from the buttocks of the wearer. Therefore, at least a part of the second adhesive region 52 having the adhesive having a relatively small basis weight is located outside the pair of squeezing portions 36, so that the sound pressure level of the peeling sound is reduced and the second adhesive region 52 is applied to the clothing. The damage can be reduced as much as possible.

Further, at least a part of the second adhesive region 52 is preferably located outside the middle height portion 32 in the width direction W. As described above, the middle-high portion 32 is provided in the area including the center in the width direction W in the excretory opening facing area S2, that is, the area facing the gluteal cleft of the wearer. Therefore, at least a part of the second adhesive region 52 is located outside the part that is likely to come into close contact with the wearer's skin. This area is an area that receives a strong force from the buttocks of the wearer. Therefore, since at least a part of the second adhesive region 52 having an adhesive having a relatively small basis weight is located outside the middle height portion 32, the sound pressure level of the peeling sound is reduced, and damage to clothes is prevented. It can be reduced as much as possible.

In the present embodiment, the third adhesive region 53 is provided in the center portion in the width direction W behind the first folding line F1, and the fourth adhesive region 54 in the width direction W is the third adhesive region 53. Located on both sides of. Here, the basis weight of the adhesive in the third adhesive area 53 is preferably larger than the basis weight of the adhesive in the fourth adhesive area 54.

Since the central portion in the width direction W of the region on the rear side of the first fold line F1 faces the upper part of the gluteal cleft of the wearer, the pressure received from the wearer while sitting is relatively small. On the other hand, the outer side portion in the width direction W of the region on the rear side of the first fold line F1 faces the upper part of the wearer's buttocks, and therefore receives relatively strong pressure from the wearer's buttocks during sitting. ..

Therefore, similarly to the excretory area S2, the basis weight of the pressure-sensitive adhesive in the third pressure-sensitive adhesive region 53 located in the central portion in the widthwise direction W in the widthwise direction W in the region behind the first fold line F1 as well. By increasing the basis weight of the adhesive in the fourth adhesive region 54 located on the outer side, the sound pressure level of the peeling sound can be reduced while maintaining the force to fix the clothes, and damage to the clothes can be minimized. It can be reduced.

The fifth adhesive region 55 may be provided in the central portion in the width direction W on the front side of the second folding line F2. The sixth adhesive region 56 may be located on both sides of the fifth adhesive region 55 in the width direction W. In the present embodiment, the basis weight of the adhesive in the fifth adhesive area 55 is substantially equal to the basis weight of the adhesive in the sixth adhesive area 56.

It is preferable that the first adhesive area 51 and the second adhesive area 52 are spaced from each other in the width direction W and extend along the front-rear direction L. On the line along the width direction, since the pressure-sensitive adhesive forming the pressure-sensitive adhesive region 50 is intermittently arranged, as compared with the case where the pressure-sensitive adhesive extends along the width direction, on the line along the width direction. The amount of adhesive in is relatively small. Therefore, when the wearer removes the absorbent article from the clothing along the front-rear direction L, the force for pulling the absorbent article may be relatively small. Further, since the first adhesive region 51 and the second adhesive region 52 extend along the front-rear direction L, the force for pulling the absorbent article 1 becomes substantially constant, and the absorbent article 1 can be smoothly peeled off from clothes. it can.

From the same viewpoint, it is preferable that the third adhesive region 53 and the fourth adhesive region 54 are also arranged at intervals in the width direction W and extend along the front-rear direction L. Similarly, it is preferable that the fifth adhesive region 55 and the sixth adhesive region 56 are also spaced from each other in the width direction W and extend along the front-rear direction L.

The first adhesive region 51 is preferably made of an adhesive having the largest basis weight among the adhesives provided in the region overlapping the absorber 30 in the thickness direction of the absorbent article. As a specific example, in the present embodiment, the basis weight of the adhesive in the first adhesive area 51 is larger than the basis weights of the adhesive in the third adhesive area 53 and the fifth adhesive area 55.

The first adhesive region 51 is provided in the central portion in the width direction W in the excretory opening opposing region S2. Since this region is a region facing the wearer's buttocks, it is difficult to receive pressure from the wearer. Therefore, by setting the basis weight of the adhesive in the first adhesive region 51 to be the largest among the adhesives provided in the region overlapping the absorber 30, the central portion in the width direction W in the excretory opening opposing region S2 is firmly fixed. And can be attached to clothing. In particular, the central portion in the width direction W of the excretion outlet facing area S2 corresponds to the area that directly receives the body fluid from the wearer, and therefore is preferably firmly attached to the clothing.

It is preferable that the basis weight of the pressure-sensitive adhesive forming the pressure-sensitive adhesive region 50 becomes smaller from the center in the width direction W toward the outside. More specifically, in the region overlapping the absorbent body 30 in the thickness direction, the basis weight of the adhesive at any position is the same as or smaller than the basis weight of the adhesive on the inner side in the width direction. The above relationship regarding the basis weight of the pressure-sensitive adhesive in the width direction W may be satisfied only at the position where the pressure-sensitive adhesive exists. That is, in the width direction W, there may be a region where the adhesive is not applied, that is, a region where the basis weight of the adhesive is 0, between the regions where the adhesive is applied. In the present embodiment, the basis weight of the adhesive in the second adhesive area 52 is smaller than the basis weight of the adhesive in the first adhesive area 51, and the basis weight of the adhesive in the fourth adhesive area 54 is in the third adhesive area 53. It is smaller than the basis weight of the adhesive.

When the wearer is seated, the pressure that the absorbent article 1 receives from the wearer increases from the center in the width direction W toward the outside. Therefore, the basis weight of the adhesive forming the adhesive region 50 decreases from the center to the outside in the width direction W, thereby reducing the basis weight of the adhesive in the region strongly receiving the pressure from the wearer, It is possible to increase the basis weight of the pressure-sensitive adhesive in an area that is not much pressured by the wearer. Therefore, it is possible to reduce the sound pressure level of the peeling sound and reduce the damage to the clothes as much as possible while maintaining the force of fixing the clothes.

In the absorbent article 1, the coating width defined by the total width of the pressure-sensitive adhesive in the pressure-sensitive adhesive region 50 on the line along the width direction becomes smaller as it goes toward the front side or the rear side in the front-rear direction L. It is preferable to have R1 and R2. When the wearer peels the absorbent article 1 from the clothing, the wearer often peels the absorbent article 1 from the front side or the back side. Since the coating width defined by the total width of the adhesive on the line along the width direction W becomes smaller toward the front side or the rear side, the adhesive force of the portion of the absorbent article 1 at the beginning of peeling is reduced. Can be lowered. Thereby, the absorbent article 1 can be easily peeled off.

In addition, the sound pressure level of the peeling sound generally tends to be high in the part of the absorbent article 1 at the beginning of peeling, but the sound pressure level at the beginning of peeling can be reduced by reducing the adhesive strength of the part at the beginning of peeling. You can

Further, when the wearer peels the absorbent article 1 from the clothing, considering that more wearers peel the absorbent article 1 from the front side of the absorbent article 1, at least at the front end of the adhesive region 50, the application width reduction region R1 is It is preferably provided.

In the application width reduction regions R1 and R2, the application area of the adhesive preferably extends to the outside in the front-rear direction L as it goes to the outside in the width direction W. As a specific example, in the present embodiment, the sixth adhesive region 56 extends to the front side of the fifth adhesive region 55 in the coating width reduction region R1. Further, in the coating width reduced region R2, the fourth adhesive region 54 extends to the rear side of the third adhesive region 53.

Accordingly, the frontmost end portion or the rearmost end portion of the adhesive region 50 can be positioned on the outer side in the width direction W as much as possible. Therefore, the region formed by the outermost end of the adhesive region 50 in the front-rear direction L and the outermost end of the adhesive region 50 in the width direction W can be made wider. Therefore, the absorbent article can be attached to the clothes more stably.

When the coating width according to the above-mentioned regulation becomes smaller toward the front side in the front-rear direction L, the coating width reduction region R1 is preferably provided on the front side of the second folding line F2. On the other hand, when the coating width according to the above-mentioned regulation becomes smaller toward the rear side in the front-rear direction L, the coating width lowering region R2 is preferably provided on the rear side of the first folding line F1.

If the application width reduction regions R1 and R2 are also present in the excretory opening opposing area S2, the adhesive force for fixing the excretory opening opposing area S2 to the clothing may be reduced. In this aspect, since the application width reduction regions R1 and R2 are provided on the rear side of the first folding line F1 or on the front side of the second folding line F2, the force for fixing the excretory opening opposing region S2 to the clothing is increased. Can be maintained.
