Further, the grip portion 65 may be configured as long as the user can hold it.

The non-fixed portion 64 may be configured to be stretchable in the extending direction. The extending direction D of the non-fixed portion 64 may be a direction from the fixed portion 62 toward the non-fixed portion 64. The fixing portion 62 and the non-fixing portion 64 are configured to be adjacent to each other in the front-rear direction L, and the extending direction D may be the front-rear direction L.

When the absorbent article 10 is discarded, the tape member 60 is caught on the main body portion 20 in a state in which the skin of the absorbent article is rolled up on the side opposite to the skin, and the rolled up absorbent article 10 is maintained. The non-fixed portion 64 of the strap member 60 is configured to be engageable with respect to the body portion 20. The non-fixed portion 64 is engaged with the structure of the main body portion 20, 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 20. The fixing portion 62 is configured to be engaged with the main body portion 20, 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.

The non-fixed portion 64 of the tape member 60 of the present embodiment is caught by the main body portion 20 when being discarded by the body adhesive portion 70. In the structure in which the tape member 60 is caught by the adhesive portion of the main body portion 20 in the main body portion 20, the non-fixing portion 64 may not be provided with an adhesive means such as an adhesive.

At least the non-fixed portion 64 of the strip member 60 is configured to be extensible in the direction of elongation D. Since the at least non-fixed portion 64 of the strap member 60 is configured to be extendable in the extending direction D, when the rolled absorbent article 10 is fixed by the strap member 60, the absorbent article 10 is easily fixed by the strap member 60 (refer to the drawing). 4). The sheet member 60 may be configured such that the entire fixing portion 62 may be elongated in the extending direction D, or only the non-fixing portion 64 may be stretched. Here, "elongation" is an elongation caused by "elastic deformation" or "plastic deformation". For example, the tape member 60 may be composed of a stretchable sheet or a film.

As shown in FIG. 2, the tape member 60 may be disposed further inside than the outer edge 20E of the main body portion 20 in a state in which it is not stretched (natural state). The sheet member 60 can be shielded by the main body portion 20 as viewed from the skin facing surface side. As shown in FIG. 4, the strip member 60 may extend outward from the outer edge 20E of the main body portion 20 in an extended state (elongated state). After the user uses the absorbent article 10, the body member 20 is rolled up in the front-rear direction L, and then the tape member 60 is extended to the outside of the outer edge 20E of the main body portion 20, and the tape member 60 can be pulled. It is caught in the main body portion 20 (see Fig. 4).

According to such a configuration, in the use of the absorbent article 10, since the tape member 60 is disposed on the non-skin opposing surface side of the back sheet 22 on the inner side of the outer edge 20E of the main body portion 20, the menstrual blood is not attached. This type of body fluid. After the use of the absorbent article 10, the user can hold the absorbent article 10 in a state of being wound up by sticking the tape member 60 extending outward to the main body adhesive portion 70 or the like. Here, since the body fluid such as menstrual blood does not adhere to the sheet member 60, the joint force of the sheet member 60 and the body adhesive portion 70 can be prevented from being lowered, or the joining force of the engaging means of the sheet member can be lowered. . Further, in the use of the absorbent article 10, since the tape member 60 is provided on the non-skin opposing surface side of the inner sheet 22, and does not extend outward from the outer edge 20E of the main body portion 20, the strip member 60 is provided. Does not directly contact the wearer's skin. Therefore, it is possible to reduce the feeling of discomfort and discomfort during use.

Further, in another embodiment, the strap member 60 may extend outward from the outer edge 20E of the main body portion 20 in a state in which it is not extended (natural state). The tape member 60 can be in a visible state when viewed from the skin facing surface side.

For other examples, the strap member 60 can also be formed from a sheet that is folded into a Z-shape. At least a part of the surface facing the body portion 20 of the strip member 60 can be fixed to the body portion 20 in a state of being folded into a Z shape. In a region where the sheets constituting the sheet member 60 overlap each other, the sheets may be joined to each other in a peelable manner. At this time, the folded tape member 60 is unfolded by the front end of the wearer blade member 60, whereby the tape member 60 is extended outward from the outer edge of the body portion 20.

It is preferable that the tape member 60 is provided on the rear side from the center of the front-rear direction L of the main body portion 20. When the user usually rolls up the absorbent article 10, the user starts to roll up from the front end edge E1 or the rear end edge E2 of the absorbent article 10 in the front-rear direction L. Among them, about 80% of the users start rolling up from the front end edge E1 of the absorbent article 10. Therefore, it is preferable that the tape member 60 is provided in a region on the rear side with respect to the center of the front-rear direction L. At least a portion of the strap member 60 may span the rear end edge of the absorbent core 23 or be disposed on the rear side of the rear end edge of the absorbent core.

The tape member 60 can be disposed on the outer side in the front-rear direction from the first crease F1 to the third crease F3. The area on the outer side in the front-rear direction of the crease of the absorbent article is likely to float toward the opposite side of the skin from the crease as a starting point due to the folding habit. Specifically, for example, when the tape member 60 is disposed between the crease and the rear end edge of the absorbent article, the region on the front side of the crease is pinched, and the time is visible from the skin facing surface side of the absorbent article. The area between the crease and the rear end edge of the absorbent article floats toward the opposite side of the skin starting from the crease. By floating the area between the crease and the rear end edge of the absorbent article, it is easy to visually recognize the non-skin pair of the absorbent article from the side of the absorbent article, etc., compared to the case where the absorbent article as a whole has a flat shape. Set the surface. Therefore, the user can easily recognize the sheet member 60 on the non-skin opposing surface side of the main body portion in a state where the absorbent article is detached from the wearing article.

Specifically, in the configuration in which the creases are one, the tape member 60 is not disposed on the creases, and can be disposed apart from the creases in the front-rear direction L. Further, in the structure in which the creases are plural, the strip member 60 may be disposed between the front side region R1 between the first crease F1 and the front end edge E1, and between the second crease F2 and the rear end edge E2. At least one of the rear side domains R2. The tape member 60 of the present embodiment is disposed in the rear side region R2 between the second crease F2 and the rear end edge E2. In the structure in which the plurality of creases are formed, the front end edge E1 and the rear end edge E2 of the absorbent article 10 are likely to have the first crease F1 and the second crease F2 which are located most outward in the front-rear direction L due to the folding habit. Float for the starting point. Since the tape member 60 is disposed in at least one of the front side region R1 and the rear side region R2, the user can easily recognize the tape member 60 when the front side region R1 and the rear side region R2 float up due to the folding habit.

Moreover, it is more preferable that the tape member 60 is provided on the rear side of the second crease F2 which is the last side of the first crease F1 to the third crease F3. About 80% of the users are the absorbent articles 10 after the roll is used from the front side. By providing the tape member 60 on the rear side of the second crease F2, most of the wearers start to roll up from the front edge E1 of the absorbent article 10, and can be wound up by the tape member 60. part.

The non-fixed portion 64 may be detachably joined to the non-skin opposing surface of the main body portion by a temporary fixing portion (not shown). By providing the temporary fixing portion, it is possible to suppress the curling of the non-fixing portion 64 or the bending of the non-fixing portion 64 before the use of the tape member 60 (at the time of manufacture or at the time of mounting). The engaging force of the temporary fixing portion can be lower than the engaging force of the fixing portion 62. Since the engaging force of the temporary fixing portion is lower than the engaging force of the fixing portion 62, the user can easily peel off the temporary fixing portion when the sheet member 60 is used, and the sheet member 60 can be operated by grasping the non-fixing portion 64. The fixing means of the temporary fixing portion may be exemplified by an adhesive, embossing, hot-melting, or ultrasonic welding, and the amount of application (area, basis weight) of the adhesive may be reduced or fixed compared to the fixing portion 62. The portion 62 further weakens the embossing press. Further, the temporary fixing portion may be formed by embossing of the outer edge of the body portion.

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 also 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 . It is preferable that the body adhesive portion is provided separately 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 may be 420 mm, and the length of the absorbent article in the widthwise direction may be 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.

Next, the identification area RA and the adjacent area RB of the tape member 60 configured as described above will be described. The identification area RA and the adjacent area RB have a function that the user can easily regard the main body unit 20 and the strip member 60 as different bodies. For example, if the user cannot recognize the presence of the strap member 60, the strap member 60 cannot be used to neatly discard the absorbent article. Further, if the user does not easily recognize the presence of the tape member 60, the user must clearly check the entire absorbent article that has been used, and the user may feel uncomfortable or may be contaminated by the body fluid. Case. Since the user easily views the main body portion 20 and the strip member 60 as different bodies, the user can easily recognize the presence of the strip member 60, and the absorbent member 10 can be cleanly discarded by the strip member 60.

The identification area RA can be configured such that the non-skin opposing surface of the main body portion 20 is easily conspicuous with respect to the adjacent region RB of the adjacent strip member 60. Specifically, it is preferable that the color difference ΔE between the identification area RA and the adjacent area RB is 3.0 or more. The applicant repeated the results of various discussions, and the user understood that in general, if the color difference ΔE is 3.0 or more, it is easy to regard two regions as different regions. By setting the color difference ΔE between the adjacent region RB of the main body portion 20 and the identification region RA of the strip member 60 to 3.0 or more, the user can easily regard the main body portion 20 and the strip member 60 as different bodies, and the sheet member can be easily recognized. The existence of 60. Further, the adjacent region RB may be a region in which the non-skin opposing surface of the main body portion 20 is adjacent to the outer edge (including the one end 60A, the side edge 60B, and the other end 60C) of the strip member 60. There is a range of regions from the outer edge of the strip member 60 toward the outer side of the strip member 60. In Fig. 2, the adjacent area RB is indicated by a diagonal line. In the adjacent region structure provided around the strip member, the color difference ΔE of at least one of the adjacent regions RB and the identification region RA may be 3.0 or more.

The color difference ΔE between the identification area RA and the adjacent area RB is measured by two points (two areas) to be measured by using a commercially available colorimeter, and CIE1976 (L) according to JIS Z 8729 *a*b*) The color space can be obtained by comparing the numerical values. Specifically, the difference between the L* values between the two points to be measured is ΔL*, the difference between a* is Δa*, and the difference between the b* values is Δb*, which can be based on the color difference ΔE=[(ΔL*)2+ (Δa*)2+(Δb*)2]1/2 is obtained.

In the configuration in which the chromatic aberration is provided in the identification region RA and the adjacent region RB, the colored portion may be provided in the identification region RA of the tape member 60, or the colored portion may be provided on the inner sheet 22 constituting the non-skin opposing surface of the main body portion 20. A colored portion may be provided in a member (for example, the absorbent core 23) located closer to the skin-facing side T1 than the inner sheet 22 of the main body portion 20, or the colored portion may be visually recognized via the inner sheet 22, or may be in the sheet member. Both the 60 and the main body portion 20 are provided with colored portions. The colored portion may include at least one of the main body colored portion 91 provided in the main body portion 20 and the strip coloring portion 92 (see FIG. 5) provided in the strip member 60.

Further, the colored portion may be composed of a sheet member such as a colored sheet member such as a pigment, or may be composed of a printed layer. Further, the state visible in the present embodiment means a state in which the illuminance (lx) is visible in an environment of 100 (lx) to 1000 (lx).

The absorbent article 10 of the present embodiment has a tape coloring portion 92 provided in the identification region RA. The tape member 60 has a base layer 66 and a printed layer 67 overlapping the base layer 66 in the thickness direction. The printed layer 67 constitutes a strip coloring portion 92. The strip coloring portion 92 composed of the printing layer 67 is provided over the entire area of the strip member 60. Therefore, the identification area RA is provided over the entire area of the strip member 60. Further, as in the first modification described later, the identification area RA may be provided in a part of the tape member 60.

Further, in the extensible web member 60, the printing layer 67 may not be provided over the entire side of the side edge of the strip member 60 in the extending direction D. The area in which the printing layer is disposed and the area in which the printing layer is not disposed are affected by the printing ink, so that the elongating ease at the time of elongation is different, and the partial elongation of the printing layer 67 is lowered. Therefore, for example, when the printing layer 67 whose partial elongation is lowered is disposed along the side edge in the extending direction D of the tape member 60, cracks may occur at the side edges of the tape member 60. In particular, the side edges along the extending direction of the tape member 60 are easily stressed when stretched, and cracks are more likely to occur. However, since the printing layer 67 is not provided over the entire side edge of the extending direction D of the tape member 60, the difference in the elongability due to the presence or absence of the printing layer 67 does not occur, and cracking can be suppressed.

The printed layer 67 can be disposed on the skin-facing side T1 of the base layer 66. Since the printing layer 67 is disposed on the skin facing surface side T1 of the base layer 66, the printing layer 67 is not disposed toward the wearing article during use of the absorbent article 10, but is disposed toward the back sheet 22. When the absorbent article 10 is used, the wearing article and the printed layer 67 are less likely to rub, and the printed layer 67 can be suppressed from being inadvertently wrinkled.

The printed layer 67 can be viewed from the non-skin opposing surface side of the absorbent article through the base layer 66. Desirably, the substrate layer 66 can be transparent or translucent. The base layer 66 is transparent or translucent, and the printed layer 67 can be more easily viewed from the non-skin opposing surface side T2 of the absorbent article via the base layer 66.

Further, in another embodiment, the printed layer 67 may be disposed on the non-skin opposing surface side T2 of the base layer 66. When the user views the absorbent article 10 from the non-skin opposing surface side T2 of the absorbent article, the printed layer 67 can be visually recognized without passing through the base layer 66, and the recognition effect by the recognition region RA can be more easily exhibited.

The colored portion may be visible from the skin facing surface side T1 of the absorbent article 10 through the main body portion 20. When the absorbent article 10 is used, the skin facing surface of the main body portion 20, that is, the surface sheet 21 faces the body of the wearer. Therefore, the user has a large chance of visually recognizing the skin of the main body portion 20. Since the colored portion is visible from the skin facing surface side T1, the user can recognize the presence of the sheet member 60 at the time of mounting.

In the region where the absorbent core 23 is not disposed, the colored portion is visible in the form of the transmissive surface sheet 21 and the inner sheet 22, and the region in which the absorbent core 23 is disposed is the surface sheet 21, the inner sheet 22, and the absorbent core 23. The form is visible. It is preferable that the colored portion is provided in a region that does not overlap the absorbent core 23. The form in which the skin facing surface side T1 of the absorbent article 10 passes through the main body portion 20 can be visually recognized.

Further, in the configuration in which the printed layer 67 is disposed on the skin-facing surface side of the base layer 66, the printed layer is not visible through the base layer 66 when viewed from the skin-facing surface side T1 of the absorbent article. 67. The presence of the strap member 60 is more easily recognized when installed.

The identification area RA is provided over the entire area in the plan view of the tape piece member 60, and is disposed in the holding portion 65. Therefore, the grip portion 65 is likely to become conspicuous with respect to the region adjacent to the grip portion 65. The user can easily recognize the holding unit 65. When the user performs the discarding operation, the discarding operation can be smoothly performed by pinching the grip position.

More preferably, the grip portion 65 may be easily conspicuous with respect to an adjacent region of the one end 60A of the adjacent sheet member 60 and an adjacent region of the side edge 60B of the adjacent sheet member 60. The chromatic aberration with respect to the identification area RA may be Δ3.0 or more in both the adjacent region of the one end 60A of the adjacent sheet member 60 and the adjacent region of the side edge 60B of the adjacent sheet member 60. Since the color difference ΔE between the three adjacent regions that are disposed around the grip portion 65 and the grip portion 65 is 3.0 or more on the non-skin opposing surface of the main body portion 20, the user can easily recognize the grip portion 65. A smooth discard operation is possible.

The identification area RA may be disposed on the outer side in the front-rear direction of the outer edges of the adhesive portions 70, 42, and 52 in the front-rear direction. It is preferable that the identification area RA is disposed outside the outer edge of the front-rear direction of the body adhesion portion 70 in the front-rear direction. The area where the adhesive portion is attached is attached to the wearing article when it is used, and is not easily visible from the opposite side of the skin of the absorbent article. On the other hand, the area on the outer side in the front-rear direction of the region where the adhesive portion is provided is not adhered to the wearing article at the time of attachment, and can be seen from the opposite side of the skin due to the lifting or lifting of the absorbent article. . Since the identification region is disposed on the outer side in the front-rear direction of the outer edge of the adhesive portion in the front-rear direction, the user can visually recognize the tape member 60 at the time of attachment, and the presence of the tape member 60 can be easily recognized.

Next, an absorbent article according to another embodiment will be described. In the following description, the same portions as those of the above-described embodiments are denoted by the same reference numerals, and their description will be omitted. FIG. 5 shows a part of a plane seen from the non-skin opposing surface side of the absorbent article 10A of the first modification and the absorbent article 10B of the second modification.

Specifically, the identification area RA is disposed in the holding portion 65 of the tape piece member 60. When the user operates the tape member 60, the user cannot grasp the fixing portion 62 to operate, and the holding portion 65 is pinched to operate. More desirably, the user operates the one end 60A of the sheet member (the end opposite to the fixed portion). By the user easily recognizing the grip portion 65, the grip portion is smoothly gripped during the operation, and the strip member 60 can be used to cleanly discard the absorbent article.

In the absorbent article 10A of the first modification, the absorbent member 10A of the first modification is provided in a configuration in which the grip portion of the sheet member is easily formed, and the strip coloring portion 92 can be provided only in the region where the grip portion 65 is disposed. Further, in the absorbent article 10B according to the second modification, the main body colored portion 91 may be provided in the adjacent region RB adjacent to the grip portion 65, and the strip colored portion 92 may be provided in the region R3 other than the grip portion 65 of the strip member 60. Further, in the absorbent article 10B of the second modification, the region R3 other than the grip portion 65 of the strap member 60 may be inconspicuous with respect to the non-skin opposing surface of the main body portion 20, and may be conspicuous with respect to the grip portion 65. Specifically, the chromatic aberration of the region R3 other than the grip portion of the strip member and the grip portion 65 (identification region RA) may be higher than the chromatic aberration of the region R3 and the adjacent region RB other than the grip portion of the strip member. According to such a configuration, the user can pinch not only the object member (sheet member) that performs the operation, but also the portion of the target member that is operated. When the user performs the discarding operation, the gripping operation can be smoothly performed by pinching the gripping position.

Next, an absorbent article according to Modifications 3 and 4 will be described with reference to Fig. 6 .

In the absorbent article 10C of the third modification and the absorbent article 10D of the fourth modification, the identification region RA is not disposed on the entire sheet member 60, and the identification region RA is disposed in a part of the sheet member 60. A strip coloring portion 92 is provided in the identification area RA. The strip coloring portion 92 may have a guide portion 95 that guides the operation of the strip member 60. The guide portion 95 may be any operator that guides the tape member 60. Specifically, in the absorbent article used for the stretched web member 60, the absorbent article 10C according to the third modification may be an arrow print indicating the stretching direction. Further, in the absorbent article used in the state in which the tape member 60 is stretched, the absorbent article 10D according to the fourth modification, which displays the "elongation" character of the property of extending the tape member 60, can be used to promote use. The operation of elongating the web member 60 is performed.

Further, the colored portion may constitute only the guide portion 95 or may have a portion other than the guide portion 95. The strip coloring portion 92 of Modification 4 may have a guiding portion 95 and a background portion 96. By having the guide portion 95 and the background portion 96, the guide portion 95 is made more conspicuous, and the smooth operation can be promoted. In such a form, the chromatic aberration of the guiding portion 95 and the adjacent region RB may be Δ3.0 or more, and the chromatic aberration of the background portion 96 and the adjacent region RB may be Δ3.0 or more. Further, in another embodiment, the main body coloring portion 91 may have a guiding portion.
