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

  That is, when a high tack force region exists in a region where pressure from the wearer is applied, particularly during 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 do. Thereby, when peeling an absorbent article from clothing, clothing may be damaged.

  On the other hand, if there is a low tack force area in a region where the pressure from the wearer is hardly applied during wearing, especially during sitting, the force to attach the low tack force area of the absorbent article to the clothing is not sufficient and absorbed. There is a possibility that the low tack force region of the property article may shift from the clothing during wearing.

  Therefore, an absorbent article that can reduce damage to clothing as much as possible while maintaining the force to fasten the clothing is desired.

  An absorbent article according to one aspect includes a front-rear direction, a width direction orthogonal to the front-rear direction, an excretion opening facing area facing a wearer's excretion opening, a back sheet facing clothing during use, and the back sheet And an adhesive region having an adhesive for fastening to clothing. The adhesive region includes a first adhesive region provided at a central portion in the width direction of the excretory mouth facing region, and second adhesive regions disposed on both sides of the first adhesive region in the width direction. The basis weight of the adhesive in the first adhesive region is larger than the basis weight of the adhesive in the second adhesive region.

  According to the absorbent article which concerns on the said aspect, the damage to clothing can be reduced as much as possible, maintaining the force fastened to clothing.

FIG. 1 is a plan view of an 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. FIG. 3 is a cross-sectional view of the absorbent article taken along line 3A-3A in FIG. FIG. 4 is a plan view of the absorbent article in the second embodiment as viewed from the side facing the garment.

(1) Outline of Embodiments At least the following matters will become apparent from the description of the present 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, an excretion opening facing area facing a wearer's excretion opening, a back sheet facing clothing during use, and the back sheet An adhesive region having an adhesive that attaches to clothing, and the adhesive region includes a first adhesive region provided at a central portion in the width direction of the excretory mouth facing region, and the width direction. A second adhesive region disposed on both sides of the first adhesive region, and the basis weight of the adhesive in the first adhesive region is larger than the basis weight of the adhesive in the second adhesive region.

  Since the central part in the width direction of the excretory opening facing area is a part facing the wearer's rupture, the pressure received from the wearer during sitting is relatively small. On the other hand, since the outer side part in the width direction of the excretion mouth facing area is a part facing the wearer's buttocks, it receives strong pressure from the wearer's buttocks during sitting.

  According to this aspect, the 2nd adhesion field is arranged in the field which receives comparatively strong pressure from a wearer's buttocks during seating. Therefore, even if the basis weight of the adhesive in the second adhesive region is relatively small, the second adhesive region is firmly fixed to clothing such as underwear by a strong pressure from the wearer.

  Moreover, the 1st adhesion area | region is generally arrange | positioned in the area | region where the pressure from the wearer received during seating is comparatively small. Here, the basis weight of the adhesive in the first adhesive region is larger than the basis weight of the adhesive in the second adhesive region. Therefore, even if the pressure received from a wearer is small, the 1st adhesion field is firmly fixed to clothing like underwear.

  In particular, since the vicinity of the central portion in the width direction of the excretion mouth facing area is a portion facing the excretion opening of the wearer, for example, the vaginal opening, the wearer can remove the absorbent article from the excretion mouth facing area from a hygiene viewpoint. There is a case where the vicinity of the center part in the width direction is not pushed strongly toward the clothing. Even in this case, since the basis weight of the adhesive in the first adhesive region is larger than the basis weight of the adhesive in the second adhesive region, the first adhesive region can be firmly attached to the clothing.

  As above-mentioned, in the absorbent article which concerns on this aspect, the basic weight of the adhesive arrange | positioned in the area | region which receives a strong pressure from a wearer, ie, the 2nd adhesion area | region, is made low. Thereby, when peeling an absorbent article from clothing, the sound pressure level of peeling sound can be made small. The sound pressure level of the peeling sound is an index representing the adhesive strength of the adhesive region to clothing. Therefore, by reducing the sound pressure level of the peeling sound, it is possible to reduce the damage caused to the clothing as much as possible.

  As mentioned above, the absorbent article which concerns on this aspect can reduce the damage to clothing as much as possible, maintaining the force fastened to clothing.

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

  Since the central portion in the width direction of the region behind the first fold line is a portion facing the top of the wearer's crack, the pressure received from the wearer during sitting is relatively small. On the other hand, the outer portion in the width direction of the region behind the first fold line is a portion facing the upper portion of the wearer's buttocks, and thus receives a strong pressure from the wearer's buttocks during sitting.

  Accordingly, the basis weight of the adhesive in the third adhesive region located in the center portion in the width direction is located in the outer portion in the width direction also in the region on the rear side of the first fold line as in the excretory mouth facing region. By making it larger than the basis weight of the adhesive in the fourth adhesive region, it is possible to reduce the sound pressure level of the peeling sound and to reduce the damage to the clothing as much as possible while maintaining the force to attach to the clothing.

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

  Thereby, when a wearer peels an absorbent article from clothes in the front-back direction, the force pulling the absorbent article becomes substantially constant, and the absorbent article can be peeled smoothly. Here, when the adhesive region (adhesive) is intermittently provided in the front-rear direction, when the absorbent article is peeled off, the portion near the boundary portion between the intermittent portion where the adhesive is not provided and the adhesive When peeled from clothing, 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, thereby causing damage to clothing. Can be suppressed.

  According to a preferred aspect, the absorbent article has a second fold line located on the front side of the excretory mouth facing area, and the adhesive region is on the front side of the second fold line at the center 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, and 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.

  In the central portion in the width direction of the region in front of the second fold 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 in front of the second fold line is subjected to strong pressure by the wearer changing his / her legs during sitting.

  Accordingly, the basis weight of the adhesive in the fifth adhesive region located in the center portion in the width direction is also set in the outer portion in the width direction in the region in front of the second fold line as in the excretory mouth facing region. By making it larger than the basis weight of the adhesive in the 6-adhesion region, it is possible to reduce the sound pressure level of the peeling sound and to reduce damage to the clothing as much as possible while maintaining the force to fasten the clothing.

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

  Thereby, when a wearer peels an absorbent article from clothes in the front-back direction, the force pulling the absorbent article becomes substantially constant, and the absorbent article can be peeled smoothly. Furthermore, an increase in peeling sound when peeling the absorbent article can be suppressed, and thereby damage to clothing can be suppressed.

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

  When a wearer peels an absorbent article from clothing, the wearer often peels from the front side or the back side of the absorbent article. The application 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 rear side, thereby reducing the adhesive strength of the part at the beginning of peeling of the absorbent article be able to. Thereby, an absorbent article can be made easy to peel.

  In addition, the sound pressure level of the peeling sound generally tends to increase at the beginning of peeling of the absorbent article, but the sound pressure level at the beginning of peeling can be reduced by lowering the adhesive strength of the beginning of peeling. it can.

  Furthermore, when the wearer peels the absorbent article from the garment, considering that there are many wearers to peel off from the front side of the absorbent article, the pressure-sensitive adhesive on the line along the width direction at least at the front end of the adhesive region It is preferable that the coating area becomes smaller toward the front side.

  According to a preferred aspect, in the application width reduction region, the adhesive application region extends to the outside in the front-rear direction as it goes outward in the width direction.

  Thereby, the frontmost end part or the rearmost end part of the adhesive region can be positioned as far as possible in the width direction. Therefore, the region formed by the extreme end in the front-rear direction of the adhesive region and the extreme end in the width direction of the adhesive region can be made wider. Therefore, an absorbent article can be attached to clothing more stably.

  According to a preferred aspect, the absorbent article has a first fold line located on the rear side of the excretory mouth facing area, and a second fold line located on the front side of the excretion mouth facing area, When the coating width becomes smaller toward the front side in the front-rear direction, the coating width reduction region is provided in front of the second fold line, and the coating width heads toward the rear side in the front-rear direction. When it becomes small, the said application | coating width fall area | region is provided in the back side rather than the said 1st fold line.

  If the application width reduction region is also present in the excretory opening facing area, the adhesive force for fixing the excretion opening facing area 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 the front side of the second fold line, it is possible to maintain the force for fixing the excretory opening facing area to the clothing.

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

  In consideration of the size of the person's buttocks and the rupture, the region within 15 mm from the center line in the width direction in the excretory opening-facing region corresponds to a position where it is difficult to receive pressure from the wearer. Therefore, the first adhesive region having the adhesive having a relatively large basis weight is provided in a range within 15 mm in the width direction from the center line, so that the central portion in the width direction of the excretory mouth facing region is firmly Can be fastened to clothing.

  According to a preferred aspect, the absorbent article is composed of a top sheet directed to the skin side of the wearer, an absorbent body between the top sheet and the back sheet, and a portion where the absorbent body is squeezed. And a pair of squeezing parts extending along the front-rear direction in the region facing the excretion opening, and at least a part of the second adhesive region is located outside the pair of squeezing parts in the width direction. .

  The excretory opening facing area is sandwiched between the wearer's legs. Thereby, the center part of the excretion mouth opposing area | region in the width direction deform | transforms so that it may stand | start up toward a wearer's explosion from a pressing part. Thereby, the center part of the excretion mouth opposing area in the width direction can be stuck to a wearer's skin.

  In this aspect, at least a part of the second adhesive region is located outside the region between the pair of squeezed portions, that is, outside the region that rises toward the wearer's crack from the squeezed portion as a base point. This region is a region that receives a strong force from the wearer's buttocks. Therefore, when at least a part of the second adhesive region having the adhesive having a relatively small basis weight is located outside the pair of pressing parts, the sound pressure level of the peeling sound is reduced, and damage to clothing is reduced. It can be reduced as much as possible.

  According to a preferred aspect, the absorbent article has an absorbent body provided on at least the excretory opening facing area on the skin surface side of the back sheet, and the absorbent body has the width in the excretion opening facing area. A middle-high portion located in a region including the center in the direction, and the thickness of the middle-high portion is larger than the thickness of the absorber located outside the middle-high portion in the width direction, and at least the second adhesive region A part is located outside the middle-high portion in the width direction.

  The middle and high portions are provided in a region including the center in the width direction in the excretory opening facing region, that is, a region facing the wearer's rupture. Since the mid-high portion is constituted by a portion having a relatively large thickness of the absorbent body, the mid-high portion is likely to be in close contact with the wearer's skin.

  In this aspect, at least a part of the second adhesive region is located outside the middle-high portion in the width direction, that is, outside the portion that is easily adhered to the wearer's skin. This region is a region that receives a strong force from the wearer's buttocks. Accordingly, at least a part of the second adhesive region having the adhesive having a relatively small basis weight is located outside the middle and high portions, thereby reducing the sound pressure level of the peeling sound and reducing the damage to the clothing as much as possible. can do.

  According to a preferred aspect, the first adhesive region and the second adhesive region are arranged at intervals in the width direction and extend along the front-rear direction.

  Since the 1st adhesion field and the 2nd adhesion field are arranged at intervals in the width direction, the field of the adhesive which constitutes the adhesion field becomes comparatively small on the line along the width direction. Therefore, when the wearer peels the absorbent article from the clothing in the front-rear direction, the force for pulling the absorbent article may be small. Moreover, since the 1st adhesion area | region and the 2nd adhesion area | region are extended along the front-back direction, the force which pulls an absorbent article becomes substantially constant, and can remove an absorbent article smoothly.

  According to one preferable aspect, the basic weight of the adhesive which comprises the said adhesion area | region becomes small as it goes outside from the center in the said width direction.

  In a state in which the wearer is seated, the pressure that the absorbent article receives from the wearer increases from the center in the width direction toward the outside. Therefore, the basis weight of the pressure-sensitive adhesive constituting the pressure-sensitive adhesive region is reduced from the center to the outside in the width direction, thereby reducing the weight basis of the pressure-sensitive adhesive in the region that receives strong pressure from the wearer. It is possible to increase the basis weight of the pressure-sensitive adhesive in a region where the pressure from the pressure is not so much. Therefore, it is possible to reduce the sound pressure level of the peeling sound and to reduce damage to the clothing as much as possible while maintaining the force to fasten the clothing.

  According to a preferred aspect, the absorbent article has a top sheet directed to the skin side of the wearer, and an absorbent body between the top sheet and the back sheet, and the first adhesive region is It is comprised with the adhesive which has the largest basic weight in the adhesive provided in the area | region which overlaps with the said absorber in the thickness direction of the said absorbent article.

  The 1st adhesion field is provided in the central part in the width direction in the excretion mouth opposing field. Since this region is a region facing the wearer's rupture, it is difficult to receive pressure from the wearer. Therefore, by making the basis weight of the adhesive in the first adhesive region the largest among the adhesives provided in the region overlapping with the absorbent body, the central portion in the width direction in the region facing the excretory mouth is firmly fixed to the clothing. Can be worn. In particular, since the central portion in the width direction of the excretory opening-facing region corresponds to a region that directly receives body fluid from the wearer, it is preferably firmly attached to the clothing.

  An absorbent article according to an aspect includes a front-rear direction, a width direction orthogonal to the front-rear direction, a back sheet facing clothing when in use, and an adhesive having an adhesive that is provided on the back sheet and is attached to the clothes. A region. The adhesive region includes a second adhesive region located in a region that receives pressure from a seated wearer and a first adhesive region provided at a position different from the second adhesive region. The basis weight of the adhesive in the first adhesive region is larger than the basis weight of the adhesive in the second adhesive region. After rolling the 200 g pressure roller on the absorbent article at a speed of 50 mm / sec in the front-rear direction with the absorbent article placed on a gold width, at a speed of 120 mm / sec in the front-rear direction. The sound pressure level of the peeling sound that occurs when the absorbent article is peeled from the gold width is 70 dB or less when the reference sound pressure level is 20 μPa.

  According to this aspect, the 2nd adhesion field is arranged in the field which receives the pressure from the wearer who sat down. Here, even if the basis weight of the adhesive in the second adhesive region is relatively small, the second adhesive region is firmly fixed to clothing such as underwear by a strong pressure from the wearer.

  In addition, the first adhesive region is disposed at a position different from the second adhesive region, that is, an area that does not receive much pressure from the seated wearer. Here, the basis weight of the adhesive in the first adhesive region is larger than the basis weight of the adhesive in the second adhesive region. For this reason, the first adhesive region is firmly fixed to a garment such as underwear even if it is not subjected to much pressure from the wearer.

  In the absorbent article which concerns on this aspect, the sound pressure level of a peeling sound when peeling an absorbent article from clothing is small. The sound pressure level of the peeling sound is an index representing the adhesive strength of the adhesive region to clothing. Therefore, by reducing the sound pressure level of the peeling sound, it is possible to reduce the damage caused to the clothing as much as possible.

  As mentioned above, the absorbent article which concerns on this aspect can reduce the damage to clothing as much as possible, maintaining the force fastened to clothing.

  FIG. 1 is a plan view of an 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. FIG. 3 is a cross-sectional view of the absorbent article taken along line 3A-3A in FIG. As the absorbent article 1, an arbitrary absorbent article such as a panty liner (orimono sheet), a sanitary napkin or an incontinence pad is assumed. In the present embodiment, a case where a sanitary napkin is used as the absorbent article 1 will be described.

  The absorbent article 1 has a front-rear direction L, a width direction W orthogonal to the front-rear direction L, and a thickness direction T. The front-rear direction L is a direction along the longitudinal direction of the absorbent article 1.

  The absorbent article 1 includes an excretion opening facing area S2 that faces the excretion opening of the wearer during use, a front area S1 that is in front of the excretion opening facing area S2, and a rear area that is behind the excretion opening facing area S2. S3.

  The absorbent article 1 may have a pair of wings 40 extending outward in the width direction W in the excretion opening facing area S2. When the absorbent article 1 is attached to clothing such as underwear, the wing 40 is folded back to the non-skin surface side of the underwear. The absorbent article 1 may have the wing adhesion area | region 60 which has the adhesive which fastens the wing 60 to clothing.

  In the absorbent article 1 having the wing 40, the boundary between the excretory opening facing area S2 and the front side area S1 is defined by the base end portion 40a on the front side of the wing 50, and the boundary between the excretion opening facing area S2 and the rear side area S3 is It is defined by the base end portion 40b on the rear side of the wing 50. Here, the base end portions 40a and 40b of the wing 50 mean the base of the wing, more specifically, the position where the absorbent article 1 is bound inward.

  The absorbent article 1 includes a top sheet 10, a back sheet 20, and an absorber 30. The absorber 30 is provided between the top sheet 10 and the back sheet 20. The topsheet 10 is directed to the wearer's skin side when the absorbent article is worn. The back sheet 20 faces the clothing side such as underwear when the absorbent article is worn. The absorber 30 is provided at least in the excretion opening facing area S2. More specifically, the absorber 30 may extend from the excretory opening facing area S2 to the front side area S1 and from the excretion opening facing area S2 to the rear side area S3. An absorbent core having an absorbent material such as pulp and SAP, and a core wrap covering the absorbent core.

  The absorbent article 1 is comprised from the part by which the absorber 30 was squeezed, and may have a pair of pressing part 36 extended along the front-back direction L in the excretion opening | mouth opposing area S2. Specifically, the pair of compressed parts 36 are provided on both sides of a center line CL extending in the front-rear direction L through the center of the absorbent article 1 in the width direction W at least in the excretion opening facing area S2. .

  The excretion opening facing area S2 is sandwiched between the wearer's legs during use of the absorbent article. Thereby, the center part of the excretion mouth opposing area | region S2 in the width direction W deform | transforms so that it may stand up toward a wearer's crack from the pressing part 36 as a base point. Thereby, the center part of the excretion mouth opposing area | region S2 in the width direction W can be stuck to a wearer's skin.

  The absorber 30 has the middle-high part 32 located in the area | region including the center in the width direction W in the excretion mouth opposing area | region S2. The middle-high portion 32 is a relatively thick absorber portion, and more specifically, is a portion thicker than the thickness of the absorber positioned outside the middle-high portion 32 in the width direction W.

  The middle-high portion 32 is provided in a region including the center in the width direction W in the excretion opening facing region S2, that is, a region facing the wearer's rupture. Since the middle / high portion 32 is configured by a portion where the thickness of the absorber 30 is relatively large, the middle / high portion 32 is easily adhered to the skin of the wearer.

  The middle / high part 32 may be provided at the inner side in the width direction W than the pair of pressing parts 36 at least in the excretion opening facing area S2. In this case, since the middle and high parts 32 can be deformed so as to rise toward the wearer's skin with the pair of compressed parts 36 as a starting point, the central part of the excretion opening facing area S2 can be brought into close contact with the wearer's skin. it can.

  The absorbent article 1 may have the 1st fold line F1 located in the rear side of the excretion opening | mouth opposing area S2, and the 2nd fold line F2 located in the front side of the excretion opening counter area S2. The first fold line F1 and the second fold line F2 extend along the width direction W. The first fold line F1 and the second fold line F2 are lines that wrap the absorbent article when the absorbent article 1 is individually packaged.

  The absorbent article 1 includes a pressure-sensitive adhesive region 50 having a pressure-sensitive adhesive that fastens the absorbent article 1 to clothing on the back sheet 20. The adhesive region 50 is provided in a region overlapping the absorbent body 30 in the thickness direction of the absorbent article 1. In the present embodiment, the adhesive region 50 includes the first adhesive region 51, the second adhesive region 52, the third adhesive region 53, the fourth adhesive region 54, the fifth adhesive region 55, and the sixth adhesive region 56. And having.

  The second adhesive region 52 is located in a region that receives pressure from the seated wearer. On the other hand, the first adhesive region 51 is provided at a position different from the second adhesive region 52. Here, the basis weight of the adhesive in the first adhesive region 51 is larger than the basis weight of the adhesive in the second adhesive region 52.

  According to this aspect, the 2nd adhesion field 52 is arranged in the field which receives the pressure from the wearer who sat down. Here, even if the basis weight of the adhesive in the second adhesive region 52 is relatively small, the second adhesive region 52 is firmly fixed to clothing such as underwear by a strong pressure from the wearer.

  The first adhesive region 51 is disposed at a position different from the second adhesive region 52, that is, in a region that does not receive much pressure from the seated wearer. Here, the basis weight of the adhesive in the first adhesive region 51 is larger than the basis weight of the adhesive in the second adhesive region 52. For this reason, the first adhesive region 51 is firmly fixed to clothing such as underwear even if it does not receive much pressure from the wearer.

  Furthermore, the adhesive region 50 is preferably configured as follows. That is, after the absorbent article 1 is placed on a gold width, a 200-g pressure roller is rolled on the absorbent article 1 in the front-rear direction L at a speed of 50 mm / sec, and then the speed is 120 mm / sec in the front-rear direction. The sound pressure level of the peeling sound generated when the absorbent article is peeled off from the gold width is 70 dB or less when the reference sound pressure level is 20 μPa.

  In the absorbent article 1 which concerns on this aspect, the sound pressure level of a peeling sound when the absorbent article 1 is peeled from clothing is small. The sound pressure level of the peeling sound is an index representing the adhesive strength of the adhesive region 50 to clothing. Therefore, by reducing the sound pressure level of the peeling sound, it is possible to reduce the damage caused to the clothing as much as possible.

  As described above, by adjusting the basis weight of the adhesive in the first adhesive region 51 and the second adhesive region 52 while adjusting the sound pressure level of the peeling sound to the above configuration, the sound is fixed to the clothing. Damage to clothing can be reduced as much as possible while maintaining strength.

  It is preferable that the 1st adhesion area | region 51 is provided in the center part in the width direction W of the excretion mouth opposing area | region S2, and the 2nd adhesion area | region 52 is arrange | positioned in the width direction W on the both sides of the 1st adhesion area | region 51. Furthermore, as described above, the basis weight of the adhesive in the first adhesive region 51 is larger than the basis weight of the adhesive in the second adhesive region 52.

  Since the central part in the width direction W of the excretion opening facing area S2 is a part facing the wearer's rupture, the pressure received from the wearer during sitting is relatively small. On the other hand, the outer side portion in the width direction W of the excretory opening facing area S2 is a portion facing the wearer's buttocks, and thus receives strong pressure from the wearer's buttocks during sitting.

  According to the said aspect, the 2nd adhesion area | region 52 is arrange | positioned in the area | region which receives a comparatively strong pressure from a wearer's buttocks during seating. Therefore, even if the basis weight of the adhesive in the second adhesive region 52 is relatively small, the second adhesive region 52 is firmly fixed to clothing such as underwear by a strong pressure from the wearer.

  Moreover, the 1st adhesion area | region 51 is generally arrange | positioned in the area | region where the pressure from the wearer received during seating is comparatively small. Here, the basis weight of the adhesive in the first adhesive region 51 is larger than the basis weight of the adhesive in the second adhesive region 52. Therefore, even if the pressure received from a wearer is small, the 1st adhesion area | region 51 is firmly fixed to clothing like underwear.

  In particular, since the vicinity of the central portion in the width direction W of the excretion opening facing area S2 is a portion facing the excretion opening of the wearer, for example, the vaginal opening, the wearer can The central portion in the width direction W may not be pushed strongly toward the clothing. Even in this case, since the basis weight of the adhesive in the first adhesive region 51 is larger than the basis weight of the adhesive in the second adhesive region 52, the first adhesive region 51 can be firmly attached to the clothing.

  As described above, in the absorbent article according to this 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 adhesive region 52 is reduced. Thereby, when peeling the absorbent article 1 from clothing, the sound pressure level of peeling sound can be made small. The sound pressure level of the peeling sound is an index representing the adhesive strength of the adhesive region 50 to clothing. Therefore, by reducing the sound pressure level of the peeling sound, it is possible to reduce the damage caused to the clothing as much as possible.

  As described above, by appropriately adjusting the positions and basis weights of the first adhesive region 51 and the second adhesive region 52, it is possible to reduce damage to the clothing as much as possible while maintaining the force to attach to the clothing. it can.

  It is preferable that the 1st adhesion area | region 51 is provided in the range L1 within 15 mm in the width direction W from the centerline CL extended in the front-back direction through the center of the absorbent article in the width direction W. Considering the size of the person's buttocks and the rupture, in the excretory opening facing area S2, the area within the range L1 within 15 mm from the center line CL in the width direction W corresponds to a position where it is difficult to receive pressure from the wearer. . Therefore, the first adhesive region 51 having the adhesive having a relatively large basis weight is provided in the range L1 within 15 mm in the width direction from the center line CL, so that in the width direction W of the excretory mouth facing region S2. The center can be firmly attached to the clothing.

  It is preferable that at least a part of the second adhesive region 52 is located outside the pair of compressed portions 36 in the width direction W. Thereby, at least one part of the 2nd adhesion area | region 52 will be located in the outer side of the area | region which stands | starts up toward a wearer's crack from the pressing part 36 as a base point. This region is a region that receives a strong force from the wearer's buttocks. Accordingly, at least a part of the second adhesive region 52 having an adhesive having a relatively small basis weight is positioned outside the pair of compressed portions 36, thereby reducing the sound pressure level of the peeling sound and Damage can be reduced as much as possible.

  In addition, it is preferable that at least a part of the second adhesive region 52 is located outside the middle-high portion 32 in the width direction W. As described above, the middle-high portion 32 is provided in a region including the center in the width direction W in the excretory opening facing region S2, that is, a region facing the wearer's rupture. Therefore, at least a part of the second adhesive region 52 is located on the outer side of the portion that is easily adhered to the wearer's skin. This region is a region that receives a strong force from the wearer's buttocks. Therefore, at least a part of the second adhesive region 52 having an adhesive having a relatively small basis weight is located outside the middle-high portion 32, thereby reducing the sound pressure level of the peeling sound and causing damage to clothing. It can be reduced as much as possible.

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

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

  Therefore, the basis weight of the adhesive in the third adhesive region 53 located at the center in the width direction W is also determined in the width direction W in the region behind the first fold line F1 as in the excretory mouth facing region S2. By making it larger than 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 is reduced while maintaining the force to attach to the clothing, and damage to the clothing is possible as much as possible. Can be reduced.

  The fifth adhesive region 55 may be provided at the center in the width direction W on the front side of the second fold 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 region 55 is substantially equal to the basis weight of the adhesive in the sixth adhesive region 56.

  It is preferable that the first adhesive region 51 and the second adhesive region 52 are arranged in the width direction W with a space therebetween and extend along the front-rear direction L. Since the adhesive constituting the adhesive region 50 is intermittently arranged on the line along the width direction, compared to the case where the adhesive extends along the width direction, on the line along the width direction. The amount of the adhesive in is relatively small. Therefore, when a wearer peels an absorbent article from the clothing along the front-rear direction L, a force for pulling the absorbent article may be relatively small. Moreover, since the 1st adhesion area | region 51 and the 2nd adhesion area | region 52 are extended along the front-back direction L, the force which pulls the absorbent article 1 becomes substantially constant, and the absorbent article 1 can be smoothly peeled from clothing. it can.

  Further, 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, the fifth adhesive region 55 and the sixth adhesive region 56 are also preferably arranged in the width direction W so as to be spaced apart from each other and extend along the front-rear direction L.

  It is preferable that the 1st adhesion area | region 51 is comprised by the adhesive which has the largest basic weight among the adhesives provided in the area | region which overlaps with the absorber 30 in the thickness direction of an absorbent article. As a specific example, in this embodiment, the basis weight of the adhesive in the first adhesive region 51 is larger than the basis weight of the adhesive in the third adhesive region 53 and the fifth adhesive region 55.

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

  It is preferable that the basis weight of the pressure-sensitive adhesive constituting 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 absorber 30 in the thickness direction, the basis weight of the adhesive at an arbitrary position is the same as or smaller than the basis weight of the adhesive on the inner side in the width direction. In addition, the said relationship regarding the basic weight of the adhesive in the width direction W should just be satisfy | filled only in the position where an 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 region 52 is smaller than the basis weight of the adhesive in the first adhesive region 51, and the basis weight of the adhesive in the fourth adhesive region 54 is in the third adhesive region 53. Less than the basis weight of the adhesive.

  In a state where the wearer is seated, the pressure that the absorbent article 1 receives from the wearer increases as it goes from the center in the width direction W toward the outside. Therefore, by reducing the basis weight of the adhesive constituting the adhesive region 50 from the center in the width direction W toward the outside, the basis weight of the adhesive in the region that strongly receives pressure from the wearer is reduced, It is possible to increase the basis weight of the pressure-sensitive adhesive in a region that does not receive much pressure from the wearer. Therefore, it is possible to reduce the sound pressure level of the peeling sound and to reduce damage to the clothing as much as possible while maintaining the force to fasten the clothing.

  In the absorbent article 1, the application width defined by the total width of the adhesive in the adhesive region 50 on the line along the width direction becomes smaller as the application width decreases 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 rear side.

  Furthermore, when the wearer peels the absorbent article 1 from the garment, considering that there are more wearers to peel off from the front side of the absorbent article 1, the application width reduction region R1 is at least at the front end of the adhesive region 50. It is preferable to be provided.

  In the application width reduction regions R1 and R2, it is preferable that the application region of the adhesive extends to the outside in the front-rear direction L toward 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 application width reduction region R1. In the application width reduction region R <b> 2, the fourth adhesive region 54 extends to the rear side of the third adhesive region 53.

  Thereby, the frontmost end part or the rearmost end part of the adhesive region 50 can be positioned as far as possible in the width direction W. Therefore, the region formed by the extreme end portion of the adhesive region 50 in the front-rear direction L and the extreme end portion of the adhesive region 50 in the width direction W can be made wider. Therefore, an absorbent article can be attached to clothing more stably.

  In the case where the coating width according to the above-mentioned regulations is reduced 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 fold line F2. On the other hand, in the case where the coating width according to the above-mentioned regulations is reduced toward the rear side in the front-rear direction L, the coating width reduction region R2 is preferably provided on the rear side of the first fold line F1.

  When the application width reduction regions R1 and R2 are also present in the excretion opening facing area S2, the adhesive force for fixing the excretion opening facing area S2 to the clothing may be reduced. In this aspect, since application width reduction area | region R1, R2 is provided in the back side from the 1st fold line F1, or the front side rather than the 2nd fold line F2, the force which fixes the excretion mouth opposing area | region S2 to clothing is carried out. Can be maintained.
