As a result of the intensive review, the inventors of the present invention found the following problems with respect to the tape member for post-processing. That is, in the past, it has not been conceived that the tape member for post-processing causes a feeling of discomfort for the installer. However, in the case of the absorbent article, it is understood that the end portion of the sheet in the vicinity of the sheet member for post-processing is rolled up, and a part of the sheet member is directly brought into contact with the skin of the wearer.

Moreover, if the sanitary napkin, the sanitary pad, the adult incontinence pad or the stool pad is attached to the wearable article of the wearer's clothing, the absorbent article is formed toward the wearer's skin due to wearing the clothing. In a state of being pressed, a sense of discomfort caused by the sheet member may occur.

In particular, in the absorbent article in which the underwear of the underwear is attached, the absorbent article is in a state of being curved in a curve corresponding to the curve of the buttocks. If the belt member having a relatively high rigidity is disposed in such a curved region, there is a case where a feeling of discomfort is caused to the wearer.
Therefore, it is desirable to have an absorbent article having a sheet member capable of suppressing a feeling of discomfort.

An absorbent article according to the aspect of the invention includes: a main body portion; and a strip member for post-processing fixed to the main body portion, wherein the main body portion includes: a front-rear direction; and a widthwise direction orthogonal to the front-rear direction; a surface sheet of the wearer's skin; an inner sheet facing the side opposite to the wearer's skin; and an absorbent body between the surface sheet and the inner sheet, wherein the sheet member has a bending rigidity that overlaps the surface sheet and the aforementioned The inner sheet and the portion of the aforementioned absorbent body have a lower bending rigidity.

(1) Outline of Embodiments At least the following matters will be understood from the description of the present specification and the drawings.

An absorbent article according to the aspect of the invention includes: a main body portion; and a strip member for post-processing fixed to the main body portion, wherein the main body portion includes: a front-rear direction; and a widthwise direction orthogonal to the front-rear direction; a surface sheet of the wearer's skin; an inner sheet facing the side opposite to the wearer's skin; and an absorbent body between the surface sheet and the inner sheet, wherein the sheet member has a bending rigidity that overlaps the surface sheet and the aforementioned The inner sheet and the portion of the aforementioned absorbent body have a lower bending rigidity.

In the attachment of the absorbent article, the end portion of the sheet in the vicinity of the sheet member for post-treatment is rolled up, and a part of the sheet member is directly brought into contact with the skin of the wearer. Here, the bending rigidity of the strip member is lower than the bending rigidity of the portion of the overlapping surface sheet and the inner sheet and the absorbent body, so that the user is less likely to feel the portion than the overlapping surface sheet and the inner sheet and the absorbent body. Regarding the sense of violation of the tape member.

According to a preferred aspect, the bending rigidity of the belt member is lower than the bending rigidity of the absorbent body.

Thereby, it is possible to further suppress the sense of discomfort caused by the tape member to the wearer.

According to a preferred aspect, the sheet member is provided on the non-skin side of the inner sheet, and the sheet member has a lower bending rigidity than the inner sheet.

In particular, since the bending rigidity of the sheet member provided on the non-skin side of the inner sheet is lower than that of the inner sheet, even if the absorbent article rubs against the skin due to the action during the loading, the wearer It is also difficult to sense the tactile sensation of the so-called tape member. Therefore, the sense of violation to the installer can be further suppressed.

According to a preferred aspect, the tape member has a fixing portion that is fixed to the main body portion, and a non-fixing portion that is not fixed to the main body portion and that does not have an adhesive.

As a result, in the attachment of the absorbent article, the end portion of the sheet in the vicinity of the sheet member for post-processing is rolled up, and a part of the sheet member is directly brought into contact with the skin of the wearer. Even in such a case, since the adhesive member is not provided in the non-fixed portion of the tape member, it is possible to prevent the tape member from adhering to the wearer's skin. Further, since the adhesive member is not provided in the non-fixed portion of the tape member, it is possible to prevent the adhesive member of the tape member itself from being inferior in the case where the tape member is adhered.

According to a preferred aspect, at least the non-fixed portion of the strip member is configured to extend in the extending direction.

Since at least the non-fixed portion of the strip member is stretchable in the extending direction, when the rolled absorbent article is fixed by the strip member, it is easy to fix the absorbent article with the strip member.

Further, when the non-fixed portion of the strip member is extended in the extending direction, the non-fixed portion of the strip member is necked in a direction orthogonal to the extending direction. Here, when the non-fixed portion has the adhesive member, the non-fixed portion of the strip member is likely to warp in the widthwise direction due to the difference in stretchability between the adhesive member and the strip member. If the non-fixed portion of the strip member is lifted, the strip member itself adheres to the adhesive member of the strip member. Therefore, when at least the non-fixed portion of the strip member is stretchable, it is preferable that the non-fixed portion does not have an adhesive.

According to a preferred aspect, the aforementioned sheet member is composed of a single sheet which is not folded.

Thereby, it is possible to further suppress the feeling of discomfort to the installer as compared with the strip member folded into a plurality of layers.

According to a preferred aspect, the tape member is made of a film that does not contain an antistatic agent.

Thereby, the tape member is easily attached to the body portion by static electricity. Since the tape member is attached to the main body portion, it is possible to suppress the winding of the tape member during the mounting of the absorbent article.

According to a preferred aspect, there is an adhesive portion provided on the non-skin side of the inner sheet.

The absorbent article such as a sanitary napkin, a sanitary pad, an adult incontinence pad or a stool pad can be fixed to the wearer's underwear by the adhesive portion on the non-skin side of the inner sheet. Class wearing clothes. Even in this case, since the rigidity of the tape member is low, it is possible to suppress the sense of discomfort of the installer derived from the tape member.

Further, after the absorbent article is used, the sheet member can be caught on the adhesive portion when the absorbent article is rolled up. Therefore, the adhesive portion can be used in both of the use for fixing the clothing and the use of the tape member for the post-treatment.

According to a preferred aspect, the absorbent article is configured to be fixed to a wearer's undergarment at the time of use, and the absorbent member has the absorbent in the front-rear direction from the rear side edge of the absorbent article. The length of the length of 1/3 of the length of the article is set in the central portion of the absorbent article in the wide side direction.

Thereby, the tape member is disposed at a position corresponding to the groove (groove) of the buttocks of the wearer. In this way, since the tape member is disposed in the recessed portion of the wearer's skin, the sense of discomfort caused by the tape member can be reduced.

According to a preferred aspect, the sheet member is provided in a range of 15% of the length of the absorbent article in the front-rear direction from the rear side edge of the absorbent article.

Thereby, the tape member is disposed at a position corresponding to the groove (groove) of the buttocks of the wearer. In this way, since the tape member is disposed in the recessed portion of the wearer's skin, the sense of discomfort caused by the tape member can be reduced.

(2) Structure of Absorbent Article Hereinafter, an absorbent article according to an embodiment will be described with reference to the drawings. The absorbent article may be an absorbent article such as a sanitary napkin, a sanitary pad, a breast milk pad, an adult incontinence pad, a stool pad or a sweat-absorbent sheet. In particular, the absorbent article may be an article that is used inside the wearing article such as a wearer's underwear.

In addition, in the description of the following drawings, the same or similar symbols are denoted by the same or similar parts. However, the figure is a schematic, and it is necessary to pay attention to the case where the ratio of each size is different from the actual one. Therefore, the specific dimensions and the like must be judged by referring to the following description. Further, even in the case where the drawings face each other, the relationship between the sizes and the portions having different ratios is included.

Fig. 1 is a plan view of the absorbent article according to the first embodiment as seen from the skin side. Fig. 2 is a plan view of the absorbent article according to the first embodiment as seen from the non-skin surface side. Here, the "skin side" is the side of the skin that faces the wearer during use. "Non-skin side" is the side opposite to the wearer's skin in use.

The absorbent article has a front-rear direction L and a broad side direction W. The front-rear direction L is a direction extending from the front side (ventral side) of the wearer toward the rear side (back side) or a direction extending from the rear side of the wearer toward the front side. The widthwise direction W is a direction orthogonal to the front-rear direction L.

The absorbent article 10 has a body portion including a surface sheet 20 facing the skin of the wearer, an inner sheet 22 facing the side opposite to the wearer's skin, and an absorption between the surface sheet 20 and the back sheet 22. Body 30. The surface sheet 20 faces the skin of the wearer in use. The inner sheet 22 faces the opposite side of the wearer's skin during use. The absorber 30 extends along the front-rear direction L of the absorbent article.

The absorbent article 10 can also have a flap 40 and a hip flap 50. The flap 40 is folded toward the non-skin side of the crotch portion of the wearing article at the time of use. The hip blade 50 is a portion that bulges toward the widthwise direction W rearward of the flap 40. The hip blade 50 is a portion that bulges outward from the outer edge of the absorber 30 in the wider side direction W.

The absorbent article 10 has a drain facing area S1 that faces the drain (e.g., vaginal opening) of the wearer during use. The excretory opening area S1 is disposed in the armpit of the installer, that is, in a region disposed between the legs of the wearer, and corresponds to an area in which the absorber 30 exists. Further, in the absorbent article 10 having the wing portion 40, the excretory opening facing region S1 is located between the wing portions 40, that is, the region where the absorbent body 30 exists.

As shown in Fig. 2, the absorbent article 10 has adhesive portions 42, 52, 70 provided on the non-skin side of the back sheet 22. The adhesive portions 42, 52, and 70 are provided with an adhesive for fixing the absorbent article 10 to the wearing article. The adhesive portion includes a body adhesive portion 70, a flap adhesive portion 42, and a flap adhesive portion 52.

The absorbent article can be fixed to the wearing garment such as the undergarment of the wearer by the adhesive portions 42, 52, 70 provided on the non-skin side of the inner sheet 22. After the absorbent article 10 is used, the sheet member 60 for post-treatment can be caught on the adhesive portions 42, 52, 70 when the absorbent article is wound up. Therefore, the adhesive portions 42, 52, and 70 can be used for both the purpose of being fixed to the clothing and the use of the sheet member for the post-treatment.

The body adhesive portion 70 is provided in a region overlapping the absorber 30 in the thickness direction of the absorbent article. It is preferable that the main body adhesion portion 70 extends continuously or intermittently from the drain opening facing region S1 toward the rear of the absorbent article 10. The body adhesive portion 70 extends in the front-rear direction L, and a plurality of the body adhesive portions 70 may be spaced apart in the width direction W.

The flap adhesive portion 42 is provided on the flap 40. The flap 40 is folded toward the wearer's wearing article during use, and is attached to the non-skin side of the wearing article by the flap adhesive portion 42. The hip-wing adhesive portion 52 is provided on the hip blade 50.

The absorbent article 10 may also have at least two fold lines extending along the widthwise direction W. In the example shown in Figs. 1 and 2, the absorbent article 10 has three fold lines F1 to F3. These fold lines F1 to F3 are lines for folding the absorbent article when the absorbent article is packaged.

The absorbent article 10 further has a sheet member 60 disposed on the inner side of the outer absorbent sheet 10 on the non-skin side of the inner sheet 22 . Therefore, the tape member 60 is in a state of being shielded by the absorbent article 10 when viewed from the skin surface side.

The tape member 60 is formed to extend beyond the outer edge of the absorbent article 10 to extend outward. Here, "stretching" is an elongation caused by "elastic deformation" or "plastic deformation". In the present specification, the tape member 60 is preferably configured to be plastically deformable. For one example, the strap member 60 may be constructed of a stretchable sheet. At this time, the strap member 60 is extended outward from the outer edge of the absorbent article 10 by the wearer pulling the sheet member 60.

The tape member 60 is a tape piece for post-treatment, and in a state in which the absorbent article 10 is agglomerated, it is only required to extend to the extent that it can be adhered to the body adhesive portion 70. Further, the tape member 60 may be made of any material as long as it can be attached to the body adhesive portion 70. Ideally, the strap member 60 is formed of a material that is more likely to adhere to the body attachment portion 70 than the surface sheet 20.

The tape member 60 has a fixing portion 62 that is fixed to the main body portion of the absorbent article 10, particularly to the non-skin surface of the absorbent article 10. That is, the fixing portion 62 of the strip member 60 is fixed to the inner sheet 22. Further, the strap member 60 has a non-fixed portion 64 that is not fixed to the body portion, particularly, the inner sheet 22 is not fixed. The surface of the non-fixed portion 64 of the strip member 60 may not have an adhesive.

When the absorbent article 10 is discarded, the tape member 60 is caught on the main body portion in a state where the absorbent article 10 is wound up on the skin-facing side of the absorbent article, and the absorbent article 10 is maintained in a state in which the absorbent article 10 is wound up. . The non-fixed portion 64 of the strap member 60 is configured to be engageable with respect to the body portion. The non-fixed portion 64 is stuck to the main body portion, and may be an adhesive portion of the main body portion 20, or may be an engaging means such as an adhesive or a hook member provided on the strip member 60. Further, the fixing portion 62 of the strap member 60 may be configured to be engageable with respect to the main body portion. The fixing portion 62 is engaged with the main body portion, and may be an adhesive portion of the main body portion, or an engaging means such as an adhesive or a hook member provided on the tape member 60.

An example of a specific structure of the absorbent article of the present embodiment is shown. The surface sheet may be composed of a gas-flow non-woven fabric (PE/PET) having a basis weight of 30 g/m ² . A second sheet may be disposed between the surface sheet and the absorbent core. In the case of the second sheet, it may be composed of the same material as the surface sheet. The surface sheet is not disposed on the outer side in the width direction of the main body portion, and the side sheet may be disposed. As for the side sheet, it can be composed of an SMS non-woven fabric (PP) having a basis weight of 13 g/m ² . The absorbent core absorbent material can be comprised of conifer kraft pulp and a superabsorbent polymer. The ratio of the weight of the superabsorbent polymer to the weight of the absorbent material as a whole may be 10%. The basis weight of the absorbent core comprising the region of the venting port opposing domain S1 may constitute a higher basis weight than the surrounding absorbent core. The absorbent core comprising the region of the venting port opposing domain S1 may have a basis weight of 950 g/m ² and the surrounding absorbent core may have a basis weight of 300 g/m ² . The inner sheet may be composed of a polyethylene film (air impermeable type) having a basis weight of 23.5 g/m ² . The absorbent article may be formed with a press portion for pressing the surface sheet and the absorbent core in the thickness direction. The body adhesive portion may be composed of a rubber-based hot melt type adhesive. The basis weight of the body adhesive portion may be 27 g/m ² . The body adhesive portion can be divided into six in the width direction. The length of each body adhesive portion in the width direction may be 5 mm, and the length of each body adhesive portion in the front-rear direction may be 320 mm. The length of the absorbent article in the front-rear direction is 420 mm, and the length of the absorbent article in the widthwise direction is preferably 200 mm. The sheet member for post-treatment can be composed of a polyethylene film having a basis weight of 35 g/m ² . The length of the strip member in the longitudinal direction may be 45 mm, and the length of the strip member in the short side direction may be 25 mm. The sheet member can be fixed to the body portion by a rubber-based hot-melt type adhesive having a basis weight of 100 g/m ² . The subsequent agent can be coated to a width of 21 mm and a length of 5 mm. The surface on the side of the inner sheet of the sheet member can be printed. A pink urethane-based ink can be used for printing. Moreover, from an elongated strip member, it may be: a basis weight of 10g / m ² polypropylene layer, a basis weight of 10g / m ² of a styrene-based rubber layer, a polypropylene layer and a basis weight of 10g / m ² layer The composition of the product.

The at least non-fixed portion 64 of the strap member 60 is configured to be extendable in the extending direction. Since the at least non-fixed portion 64 of the strap member 60 is configured to extend in the extending direction, when the rolled absorbent article 10 is fixed by the strap member 60, the absorbent article 10 can be easily fixed by the strap member 60 (refer to Figure 4).

The strap member 60 can be constructed from a single sheet that is not folded. As a result, it is possible to further suppress the feeling of discomfort (decreased tactile sensation) to the wearer when the absorbent article is attached, as compared with the tape member that is folded into a plurality of layers.

In the attachment of the absorbent article 10, the end portion of the sheet near the sheet member 60 for post-processing is wound up, and a part of the sheet member 60 is directly brought into contact with the skin of the wearer. Even in such a case, since the adhesive member is not provided in the non-fixed portion 64 of the tape member 60, the tape member 60 can be prevented from adhering to the wearer's skin.

Further, since the adhesive member is not provided in the non-fixed portion 64 of the tape member 60, it is possible to prevent the adhesive member of the tape member itself from being inferior in the case where the tape member is adhered.

Specifically, when the non-fixed portion 64 of the strip member 60 is extended in the extending direction, the non-fixed portion 64 of the strip member 60 is shrunk in a direction orthogonal to the extending direction. Here, when the non-fixed portion 64 has an adhesive material, the non-fixed portion 64 of the tape member 60 is easily warped in the widthwise direction due to the difference in stretchability between the adhesive member and the tape member 60. If the non-fixed portion 64 of the strip member 60 is tilted, the strip member itself may adhere to the adhesive member of the strip member 60. When the surface of the non-fixed portion 64 of the tape member 60 does not have an adhesive material, it is possible to prevent the tape member 60 itself from sticking to the adhesive member of the tape member 60.

The front end portion of the strip member 60 in the extending direction may face the opposite side to the fixing portion 62. At this time, when the tape member 60 is extended beyond the outer edge of the absorbent article 10, the force of the fixing portion 62 formed on the tape member 60 is actuated only in the extending direction. Thereby, since the force acting on the fixing portion 62 can be minimized, the fixing strength of the tape member 60 can be maintained.

After the user uses the absorbent article 10, the absorbent article 10 is wound up in the front-rear direction L, and then the tape member 60 can be extended outward from the outer edge of the absorbent article 10 (see FIG. 4). In use, since the tape member 60 is disposed on the non-skin side of the inner sheet 22 on the inner side of the outer edge of the absorbent article 10, the body fluid such as menstrual blood does not adhere to the sheet member 60. After the user uses the absorbent article 10, the tape member 60 extending outward is attached to the adhesive portion 70 provided at the other portion of the inner sheet 22, whereby the absorbent article 10 can be maintained after being agglomerated. status. Here, since the body fluid such as menstrual blood does not adhere to the tape member 60, the bonding force between the tape member 60 and the adhesive portion 70 can be prevented from being lowered, whereby the absorbent article 10 can be easily maintained in a small group. State of affairs.

Further, in the use of the absorbent article 10, since the tape member 60 is provided on the non-skin side of the back sheet 22, it does not extend outward than the outer edge of the absorbent article 10, so the sheet member 60 does not Directly touch the wearer's skin. Therefore, it is possible to reduce the feeling of discomfort and discomfort during use.

The sheet member 60 is an absorbent article provided in the widthwise direction W within a range of 1/3 of the length of the absorbent article 10 in the front-rear direction L from the rear side edge E2 of the absorbent article 10. The central part of 10 is ideal. Thereby, the tape member 60 is disposed at a position corresponding to the groove (groove) of the buttocks of the wearer. As described above, since the tape member 60 is disposed in the recessed portion of the wearer's skin, the sense of discomfort caused by the tape member 60 can be reduced.

It is preferable that the tape member 60 is provided in a range of 15% of the length of the absorbent article 10 in the front-rear direction L from the rear side edge E2 of the absorbent article 10. Thereby, the tape member 60 is disposed at a position corresponding to the groove (groove) of the buttocks of the wearer. As described above, since the tape member 60 is disposed in the recessed portion of the wearer's skin, the sense of discomfort caused by the tape member 60 can be reduced.

The sheet member 60 is preferably formed to extend toward the rear side of the rear side edge of the absorbent article 10. It is more preferable that the tape member 60 is provided on the rear side of the fold line F3 which is the last side of the fold lines F1 to F3. About 80% of the users are the absorbent articles 10 after the roll is used from the front side. By constituting the strap member 60, the rear side edge of the absorbent article 10 can be extended toward the rear side, and a plurality of users extend the strap member 60 in the winding direction, and the strap member 60 can be mounted. To the body adhesive portion 70.

It is preferable that the body adhesive portion 70 is provided with the tape member 60 on an imaginary line extending in the front-rear direction L. More preferably, the body attaching portion 70 sets the strip member 60 on an imaginary line extending in a direction opposite to the extending direction. Thereby, the tape member 60 is extended toward the rear side from the rear side edge E2 of the absorbent article, and if the tape member 60 is directly taken along the rolled absorbent article 10, the body adhesive portion 70 is attached to the tape. On the sheet member 60. Therefore, the user can easily maintain the absorbent article 10 in a state of being agglomerated without pulling the sheet member 60 obliquely toward the position of the body adhesive portion 70.

The width of the main body adhesive portion 70 provided on the above-described imaginary line in the direction orthogonal to the extending direction is preferably larger than the width in the direction orthogonal to the extending direction of the strip member 60. Thereby, when the tape member 60 is stretched in the extending direction in a state in which the absorbent article 10 is wound up, even if the tape member 60 is not straight, it is pulled out slightly, and the tape member 60 is not. The fixing portion 64 is also located at the body adhesive portion 70. Therefore, it is easy for the user to attach the tape member to the adhesive portion.

The body adhesive portion 70 may be provided at a plurality of intervals in the width direction W. At this time, the width W1 of the strip member 60 in the widthwise direction W is preferably larger than the interval W2 between the body adhesive portions 70 in the wide-side direction W. Thereby, it is possible to prevent the user from pulling out the strip member 60 at the destination without the presence of the body adhering portion 70. Therefore, the user easily attaches the tape member 60 to the adhesive portion 70.

It is preferable that the surface of the tape member 60 abutting on the side of the body adhesion portion 70 is smooth. For example, the surface roughness of the KES of the surface of the strip member 60 that abuts on the side of the body adhesion portion 70 may be in the range of about 0.5 to 1.5. Since the surface of the tape member 60 abutting on the side of the body adhesive portion 70 is smooth, the contact area with respect to the tape member 60 of the body adhesive portion 70 can be increased. Thereby, when the tape member 60 is adhered to the main body adhesive portion 70 in a state where the absorbent article is 10, the tape member 60 can be prevented from falling off from the main body adhesive portion 70.

Further, the surface roughness of the KES can be measured using, for example, a surface test apparatus (KES-FB4-AUTO-A) manufactured by Kato Tekko Co., Ltd., Japan. Specifically, the tape member (test piece) to be measured is first placed on the measuring machine of the surface test apparatus. Then, the measurement terminal was moved in the measurement direction while the measurement terminal of the surface test apparatus was brought into contact with the test piece while the test piece was fixed in such a manner that no wrinkles were formed on the test piece. Further, the test piece may be cut into a size in which the length of the measurement direction is 100 mm and the width in the direction orthogonal to the measurement direction is 50 mm. The surface roughness of the aforementioned KES is defined by the value of the thickness (SMD) obtained from the measurement.

Both the inner sheet 22 and the strip member 60 are made of a film, for example, a synthetic resin film. Further, it is preferable that at least one of the surface in contact with the back sheet 22 of the sheet member 60 and the surface of the sheet member 60 contacting the back sheet 22 is preferably not subjected to antistatic treatment.

Further, the tape member 60 may be composed of a film containing no static preventing agent. Thereby, the tape member 60 is easily attached to the body portion by static electricity. Since the tape member 60 is attached to the main body portion, it is possible to suppress the winding of the tape member 60 in the attachment of the absorbent article 10.

At least a part of the fixing portion 62 of the tape member 60 is preferably overlapped with the absorber 30 in the thickness direction. The region in which the absorber 30 is present is particularly a region of high rigidity in the absorbent article 10. Since the fixing portion 62 of the tape member 60 and the absorber 30 overlap in the thickness direction, when the absorbent article 10 is wound up, the fixing portion 62 of the tape member 60 located in the region of high rigidity together with the absorbent article 10 Surely bent. Thus, by the fixing portion 62 of the strip member 60 being surely bent, the free end of the strip member 60 is more easily floated from the inner sheet 22. Therefore, it becomes easier for the user to pinch the tape member 60 to operate.

The bending rigidity of the belt member 60 is lower than that of the portions of the overlapping surface sheet 20 and the inner sheet 22 and the absorbent body 30. Here, in the attachment of the absorbent article, the end portion of the sheet in the vicinity of the sheet member for post-processing is rolled up, and a part of the sheet member 60 may be directly brought into contact with the skin of the wearer. Here, the bending rigidity of the tape member 60 is lower than that of the overlapping surface sheet 20 and the inner sheet 22 and the absorbent body 30, so that the wearer does not easily perceive the overlapping surface sheet 20 and the inner sheet 22 and The portion of the absorbent body 30 is more ambiguous.

It is preferable that the bending rigidity of the belt member 60 is lower than the bending rigidity of the absorbent body 30. Thereby, the sense of discomfort caused by the strap member 60 to the wearer can be further suppressed. The bending rigidity of the tape member 60 is preferably 1/10 or less, and more preferably 1/30 or less, of the bending rigidity of the absorbent body 30.

Further, the tape member 60 is provided on the non-skin side of the inner sheet 22, and the bending rigidity of the sheet member 60 is lower than the bending rigidity of the inner sheet 22.

In particular, since the bending rigidity of the tape member 60 provided on the non-skin side of the inner sheet 22 is lower than that of the inner sheet 22, the absorbent article 10 is rubbed against the skin even by the action during the loading. It is also difficult for the installer to be aware of the tactile sensation of the so-called strap member 60. Therefore, the sense of violation to the installer can be further suppressed.

That is, since the tape member 60 is in a state of being covered by the more rigid inner sheet 22, the wearer hardly feels the rigidity of the tape member 60 during the loading.

Further, the inventors of the present invention measured the rigidity of the tape member for post-treatment of various absorbent articles circulating in the market, but found that the bending rigidity of the tape member 60 was smaller than that of the inner sheet 22 and the absorbent body. 30. The rigidity of each of the portions of the overlapping surface sheet 20 and the inner sheet 22 and the absorbent body 30 is lower.

Further, the rigidity of each of the strip member 60, the inner sheet 22, the absorbent body 30, the overlapping surface sheet 20 and the inner sheet 22, and the portion of the absorbent body 30 is determined by the taper method according to the standard specification JIS P-8125. measuring.

For example, a test piece having a width of 38.1 mm and a length of 70 mm is first collected from a member (sheet) that must be a measurement target. Next, the thickness of the test piece was measured by a thickness gauge (for example, 44 mmφ 3 g/m ² manufactured by PEACOCK). Next, the test piece was placed in a Taber Stiffness Tester of the Yasuda Precision Mechanism. Next, the test piece was placed between the rolls of a Taber Stiffness Tester, and the jig was sandwiched by the thickness of the test piece. In addition, the upper end of the test piece was aligned with the upper surface of the jig. The interval between the test piece and the test piece was adjusted to about 0.5 mm in such a manner that the roller did not press the test piece. Let the test piece bending device of the Taber Stiffness Tester rotate, and stop the rotation of the bending device at the point where the 15 degree mark indicating the bending device of the test piece coincides with the pointer of the load pendulum, and read the pendulum at this time. The pointer indicates the load scale of the bending device. Immediately, the load swing is rotated in the opposite direction, and the load scale is read in the same manner, and the average value of the load scales in the left and right directions is obtained. In addition, the auxiliary weight is arbitrarily selected, so that the indicated load scale is entered in the range of 15 to 85% of the maximum scale. Then, the bending rigidity (softness (g·cm)) of the test piece was calculated based on the equation of "softness (g·cm) = average value of the load scale × 10 × weight).

The width of the fixing portion 62 in the direction orthogonal to the extending direction is preferably shorter than the width W1 of the strip member 60 in the direction orthogonal to the extending direction. Thereby, when the non-fixed portion 64 of the strip member 60 is pulled, a strong force is applied in the extending direction at a width of the fixing portion 62 which is shorter than the entire width of the strip member 60, so that the strip can be reduced. The necessary tension of the non-fixed portion 64 of the member 60 is extended.

The width of the fixing portion 62 in the direction orthogonal to the extending direction is more preferably half or more of the width W1 of the strip member 60 in the direction orthogonal to the extending direction. By increasing the width of the fixing portion 62 in the direction orthogonal to the extending direction, it is possible to suppress the unfixed portion 64 of the tape member 60 from being wound up in the widthwise direction W. Thereby, it is easy to maintain the state in which the non-fixed portion 64 of the strip member 60 is planarly developed, and it is easy to form the sheet member 60 in a state in which the absorbent article 10 is agglomerated.

The non-fixed portion 64 of the strap member 60 may also be provided at a position away from the absorber 30. For example, it is preferable that the non-fixed portion 64 of the strip member 60 is provided at a position away from the absorber 30 by 50 mm or more. When the absorbent body 30 absorbs a liquid such as a body fluid of the wearer, the inner sheet 22 which overlaps with the absorbent body 30 in the thickness direction is twisted, and the inner sheet 22 is wrinkled. In the case where the sheet member 60 is present at such a place where wrinkles are generated, a space is generated in a portion between the sheet member 60 and the back sheet 22 due to the generation of wrinkles. Thereby, the tape member 60 cannot be in close contact with the inner sheet 22, and the tape member 60 is easily moved by rubbing the inner sheet 22 in the attachment of the absorbent article 10. As a result, the tape member 60 is agglomerated or bent toward the wide side, and the tape member 60 becomes difficult to use. In this aspect, the non-fixed portion 64 of the strip member 60 is provided at a position away from the absorber 30 in the thickness direction, that is, at a position where wrinkles are less likely to occur even if the absorber 30 absorbs liquid and the sheet 22 is inside. Therefore, it is possible to suppress the fact that the tape member 60 is agglomerated or bent in the wide side direction during the mounting.

An embossing (compression portion) of a predetermined pattern can also be formed in the absorber 30. Further, the absorber 30 may be provided with a low basis weight region having a basis weight lower than that of the surrounding absorber 30. At this time, it is preferable that the tape member 60 is overlapped with the embossing formed in the absorbent body 30 or in the low basis weight region provided in the absorbent body 30 in the thickness direction. If the sheet member 60 overlaps with the embossing formed on the absorbent body 30 or the low basis weight region provided in the absorbent body 30 in the thickness direction, between the belt member 60 and the inner sheet 22 (absorbent body 30) It is easy to create gaps. Therefore, when the absorbent article 10 is wound up, the sheet member 60 is more likely to float from the inner sheet 22, and it is easier for the user to pinch the sheet member 60 for operation.

It is preferable that the strip member 60 has at least a region where the fixing portion 62 is removed from a position where the flap adhesive portion 42, the hip flap adhering portion 52, and the body adhesive portion 70 do not overlap each other. Thereby, when the absorbent article 10 is wound up, the tape member 60 is easily floated from the inner sheet 22. Thus, it becomes easier for the user to pinch the tape member 60 for operation.

The flap adhesive portion 42, the hip flap adhesive portion 52, and the body adhesive portion 70 are provided in a movable state of the non-fixed portion 64 that does not extend along the non-fixed portion 64 in the expanded state of the absorbent article 10 (FIG. 2). The area S) is ideal for the outside. That is, the strip member 60 does not adhere to the flap adhesive portion 42, the hip flap adhesive portion 52, or the body adhesive portion 70 in a state where it is not extended. Thereby, it is possible to prevent the sheet member 60 from adhering to the flap adhesive portion 42, the hip blade adhesive portion 52, and the body adhesive portion 70 in the attachment of the absorbent article 10.

Further, embossing can be formed along the outer edge of the absorbent article 10. This embossing can be applied, for example, to the surface sheet 20 and the inner sheet 22. At this time, a part of the embossing may also be formed on the strip member 60.
