In the example shown in Figs. 1 and 2, the fold line of the absorbent article 10 has a first fold line F1, a second fold line F2, and a third fold line F3. The first fold line F1 is a fold line closest to the shear edge E1 of the absorbent article 10. The second fold line F2 is a fold line closest to the rear edge E2 of the absorbent article 10. The third fold line F3 is disposed between the first fold line F1 and the second fold line F2. In addition, four or more folding lines may be formed. The fold line is a line for folding the absorbent article 10 with the skin-facing surface side T1 of the absorbent article inward when packaging the absorbent article.

The tape member 60 is fixed to the main body 20. The tape member 60 may have a fixing portion 62 fixed to the body portion 20 as shown in FIG. 3. The fixing part 62 may be formed at one end of the tape member 60. The fixing portion 62 may be fixed to the body portion 20 by means of an adhesive or the like. The fixing portion 62 may be fixed to the back sheet 22 constituting the non-skin surface of the body portion 20.

Further, the tape member 60 may have a non-fixing portion 64 that is not fixed to the body portion 20. The non-fixing portion 64 is not fixed to the back sheet 22, but is a portion for which the user operates the tape member 60. More specifically, when using the tape member 60, the user grips the non-fixed portion to pull the non-fixed portion 64 or fixes the non-fixed portion 64 to the body portion 20. At least a portion of the non-fixing portion 64 constitutes a gripping portion 65 that can be gripped by a user. The gripping portion 65 may be all over the non-fixing portion 64, or may be formed on one end of the non-fixing portion 64 on the opposite side to the fixed portion 62. The tape member of the present embodiment has one end 60A on the side opposite to the fixed part, the other end 60C on the fixed part side, and a pair of side edges 60B extending from one end 60A toward the other end 60C. Has. The gripping portion 65 is a region sandwiched by a pair of side edges 60B including one end 60A of the tape member 60 and extending from one end 60A toward the other end 60C of the tape member. It is extended. On the other hand, the gripping portion 65 may be configured so that the user can grip it.

The non-fixing portion 64 may be configured to be extendable in the extending direction. The extension direction D of the non-fixing portion 64 may be a direction from the fixed portion 62 to the non-fixing portion 64. In a configuration in which the fixed portion 62 and the non-fixing portion 64 are adjacent in the front-rear direction L, the extension direction D may be the front-rear direction L.

When disposing of the absorbent article 10, the tape member 60 is fixed to the body part 20 in a dried state with the side facing the skin of the absorbent article inwardly, so that the absorbent article 10 is kept in a rolled state. It may be configured. The non-fixing portion 64 of the tape member 60 is configured to be fixable to the body portion 20. The configuration in which the non-fixing portion 64 is fixed to the body portion 20 may be a bonding means of the body portion 20 or a pressure-sensitive adhesive formed on the tape member 60 or a fixing means such as a hook member. Further, the fixing portion 62 of the tape member 60 may be configured to be capable of being fixed to the body portion 20. The structure in which the fixing part 62 is fixed to the main body 20 may be a bonding means of the main body 20 or a fixing means such as an adhesive formed on the tape member 60 or a hook member.

The non-fixing portion 64 of the tape member 60 of the present embodiment is fixed to the body portion 20 at the time of disposal via the body adhesive portion 70. In the configuration in which the tape member 60 is fixed to the body portion 20 by the adhesive portion of the body portion 20, the non-fixing portion 64 does not need to be provided with a fixing means such as an adhesive.

At least the non-fixing portion 64 of the tape member 60 is configured to be extendable in the extending direction D. Since at least the non-fixing portion 64 of the tape member 60 is configured to be stretchable in the stretching direction D, only when fixing the absorbent article 10 with the tape member 60, the tape member 60 It becomes easy to fix the absorbent article 10 (see Fig. 4). The tape member 60 may be configured such that the entirety including the fixing portion 62 can be stretched in the stretching direction D, or only the non-fixing portion 64 may be configured to be stretchable. Here, "elongation" includes elongation by "elastic deformation" or "plastic deformation". As an example, the tape member 60 may be composed of an elastic sheet and a film.

As shown in FIG. 2, the tape member 60 may be disposed inside the outer edge 20E of the main body 20 in a state in which it is not stretched (natural state). The tape member 60 may be in a state hidden in the body portion 20 when viewed from the side facing the skin. As shown in FIG. 4, the tape member 60 may extend outward from the outer edge 20E of the main body 20 in an extended state (stretched state). After use of the absorbent article 10, the user makes the body part 20 in the front-rear direction (L), and then extends the tape member 60 outward than the outer edge 20E of the body part 20, The tape member 60 can be fixed to the part 20 (see FIG. 4).

According to this configuration, when the absorbent article 10 is in use, the tape member 60 is disposed inside the outer edge 20E of the main body 20 on the non-skin side of the back sheet 22. Therefore, body fluids such as acupuncture points do not adhere. After use of the absorbent article 10, the user can hold the absorbent article 10 in a bundled state by fixing the tape member 60 extending outward to the body adhesive portion 70 or the like. Here, since body fluids such as acupuncture points are not adhered to the tape member 60, a decrease in the bonding force between the tape member 60 and the main body adhesive portion 70, or a decrease in the bonding force between the tape member fixing means can be prevented. . In addition, during the use of the absorbent article 10, the tape member 60 is formed on the non-skin facing side of the back sheet 22, and does not extend outward from the outer edge 20E of the body portion 20. Therefore, the tape member 60 does not directly contact the wearer's skin. Therefore, the feeling of discomfort or discomfort during use can be reduced.

In addition, in another form, the tape member 60 may extend outward from the outer edge 20E of the main body 20 in a state in which it is not stretched (natural state). The tape member 60 may be in a state that can be visually recognized when viewed from the side facing the skin.

As another example, the tape member 60 may be composed of a sheet folded in a Z-shape. In the state of being folded in a Z-shape, at least a part of the surface of the tape member 60 facing the body portion 20 may be fixed to the body portion 20. In a region where the sheets constituting the tape member 60 overlap each other, the sheets may be bonded so as to be peelable. In this case, by the wearer pulling the tip end of the tape member 60, the folded tape member 60 is unfolded, whereby the tape member 60 extends outward than the outer edge of the body portion 20.

It is preferable that the tape member 60 is formed behind the center of the front-rear direction L of the main body 20. When a user normally bundles the absorbent article 10, the user starts to bundle the absorbent article 10 in the front-rear direction L from the front edge E1 or the rear edge E2. Among them, about 80% of users start to bundle up from the shear edge E1 of the absorbent article 10. Therefore, it is preferable that the tape member 60 is formed in a region located at the rear side with respect to the center of the front-rear direction L. At least a part of the tape member 60 may extend over the trailing edge of the absorbent core 23 or may be disposed behind the trailing edge of the absorbent core.

The tape member 60 may be disposed outside the first fold line F1 to the third fold line F3 in the front-rear direction. The area outside the fold line of the absorbent article in the front-rear direction is likely to float to the skin-facing surface side with the fold line as a starting point by the fold mark. Specifically, for example, in the case where the tape member 60 is disposed between the fold line and the rear edge of the absorbent article, the fold line and the absorbent property are visually recognized from the skin-facing side of the absorbent article by gripping the area in front of the fold line. The area between the trailing edge of the article floats on the side facing the skin from the fold line. Since the area between the fold line and the rear edge of the absorbent article floats, it becomes easier to visually recognize the skin non-facing surface of the absorbent article from the side of the absorbent article or the like than when the entire absorbent article has a flat shape. Accordingly, it becomes easy for the user to visually recognize the tape member 60 located on the non-skin surface side of the body portion in a state where the absorbent article is removed from the worn article.

Specifically, in a configuration having one fold line, the tape member 60 may be disposed not on the fold line but spaced apart from the fold line in the front-rear direction L. In addition, in a configuration having a plurality of fold lines, the tape member 60 includes a front region R1 between the first fold line F1 and the front edge E1, and the second fold line F2 and the rear end edge. It may be arranged in at least one of the rear regions R2 between (E2). The tape member 60 of this embodiment is disposed in the rear region R2 between the second folding line F2 and the trailing edge E2. In the configuration in which a plurality of fold lines are formed, the front edge E1 and the rear edge E2 of the absorbent article 10 are first folded outside the most front-rear direction L by a crease. It is easy to float from the line F1 and the second fold line F2. Since the tape member 60 is disposed in at least one of the front region R1 and the rear region R2, the user can use the tape when the front region R1 and the rear region R2 are floated by the fold marks. The member 60 becomes easy to recognize.

In addition, it is more preferable that the tape member 60 is formed on the rear side of the second fold line F2 at the rearmost of the first fold lines F1 to the third fold lines F3. About 80% of users start rolling the absorbent article 10 after use from the front side. Since the tape member 60 is formed on the rear side of the second fold line F2, many users start to bundle up from the front edge E1 of the absorbent article 10, and the end of the tape member 60 Can be fixed by

The non-fixing portion 64 may be detachably bonded to the non-skin surface of the body portion by a temporary portion (not shown). By forming the temporary portion, it is possible to suppress the non-fixing portion 64 from curling or folding of the non-fixing portion 64 before use (at the time of manufacture or wearing) of the tape member 60. The bonding force of the temporary portion may be lower than the bonding force of the fixing portion 62. Since the bonding force of the temporary portion is lower than the bonding force of the fixing portion 62, the user easily peels the temporary portion when using the tape member 60, and manipulates the tape member 60 by holding the non-fixing portion 64. can do. As the fixing means of the temporary part, adhesive, embossing, heat welding, ultrasonic welding can be exemplified, and the amount of adhesive applied (area, unit weight) is less than that of the fixing part 62, or embossing is less than that of the fixing part 62. It is possible to weaken the compression of boss processing. Further, the temporary portion may be formed by embossing the outer edge of the body portion.

An example of a specific configuration of the absorbent article of this embodiment is shown. The top sheet may be formed of an air-through nonwoven fabric (PE/PET) having a unit weight of 30 g/m 2. A second sheet may be formed between the top sheet and the absorbent core. As the second sheet, it may be made of the same material as the top sheet. Outside of the body portion in the width direction, a top sheet may not be disposed, but a side sheet may be disposed. As a side sheet, you may comprise SMS nonwoven fabric (PP) with a unit weight of 13 g/m 2. The absorbent material of the absorbent core may be composed of softwood kraft pulp and a super absorbent polymer. The ratio of the weight of the superabsorbent polymer to the total weight of the absorbent material may be 10%. The unit weight of the absorbent core in the region including the excretory facing region S1 may be configured to be higher than the unit weight of the surrounding absorbent core. The unit weight of the absorbent core in the region including the excretory facing region S1 may be 950 g/m 2, and the unit weight of the surrounding absorbent core may be 300 g/m 2. The back sheet may be formed of a polyethylene film (non-ventilated type) having a unit weight of 23.5 g/m 2. The absorbent article may have a pressing portion formed by pressing the top sheet and the absorbent core in the thickness direction. The body adhesive portion may be formed of a rubber-based hot melt adhesive. The unit weight of the body adhesive portion may be 27 g/m 2. Six main body adhesive portions may be formed at intervals 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 in the front-rear direction of the absorbent article may be 420 mm, and the length in the width direction of the absorbent article may be 200 mm. The tape member for post-treatment may be formed of a polyethylene film having a unit weight of 35 g/m 2. The length of the tape member in the longitudinal direction may be 45 mm, and the length of the tape member in the width direction may be 25 mm. The tape member may be fixed to the body portion by a rubber-based hot melt adhesive having a unit weight of 100 g/m 2. The adhesive may be applied in a range of 21 mm in width and 5 mm in length. Printing may be performed on the side of the back sheet side of the tape member. For printing, a pink urethane-based ink may be used. Further, as the elongated tape member, a polypropylene layer having a unit weight of 10 g/m 2, a styrene rubber layer having a unit weight of 10 g/m 2, and a polypropylene layer having a unit weight of 10 g/m 2 may be laminated.

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 of making it easy for the user to recognize the main body 20 and the tape member 60 as separate bodies. For example, if the user does not recognize the presence of the tape member 60, the absorbent article cannot be disposed of cleanly using the tape member 60. In addition, if it is difficult for the user to recognize the presence of the tape member 60, the user needs to check the entire used absorbent article to every corner, causing discomfort or getting his hands dirty due to body fluids. There is a risk of occurrence. By making it easier for the user to recognize the main body 20 and the tape member 60 as separate bodies, the user can easily recognize the existence of the tape member 60 and clean the absorbent article 10 by the tape member 60 Can be discarded.

The identification area RA may be configured to be conspicuous with respect to the adjacent area RB adjacent to the tape member 60 on the non-skin surface of the main body 20. Specifically, the color difference ΔE between the identification area RA and the adjacent area RB may be 3.0 or more. As a result of repeated examinations by the applicant in various ways, it has been found that generally, when the color difference ΔE is 3.0 or more, it is easy to recognize the two areas as different areas. Since the color difference ΔE between the adjacent area RB of the main body 20 and the identification area RA of the tape member 60 is 3.0 or more, the user can recognize the main body 20 and the tape member 60 as separate bodies. It is easy, and the presence of the tape member 60 becomes easy to recognize. On the other hand, the adjacent region RB is the outer edge of the tape member 60 on the non-skin surface of the main body 20 (including one end 60A, a side edge 60B, and the other end 60C) It may be an area adjacent to. It is an area having a certain range toward the outside of the tape member 60 from one outer edge of the tape member 60. In Fig. 2, the adjacent region RB is illustrated by drawing an oblique line. In a configuration in which adjacent regions are formed on all sides of the tape member, the color difference ΔE between at least one adjacent region 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 colorimetrically colored using a commercially available colorimeter for two points (two areas) to be measured, and is specified in JIS Z 8729. It can be obtained by comparing numerical values based on the CIE1976 (L*a*b*) color space. Specifically, when the difference between the two points to be measured is ΔL*, the difference between a* is Δa*, and the difference between b* values is Δb*, the color difference ΔE=[(ΔL*)2+(Δa*)2+ It is calculated by (Δb*)2]1/2.

In the configuration of forming a color difference between the identification region RA and the adjacent region RB, a colored portion may be formed in the identification region RA of the tape member 60, and constitutes the non-skin surface of the body portion 20. A colored portion may be formed on the back sheet 22, and a colored portion is formed on a member (e.g., absorbent core 23) positioned on the skin-facing surface side T1 than the back sheet 22 of the body portion 20, and The colored portion may be configured to be visible through the sheet 22, or colored portions may be formed on both the tape member 60 and the body portion 20. The colored portion may have at least one of a main colored portion 91 formed in the body portion 20 and a tape colored portion 92 formed in the tape member 60 (see FIG. 5 ).

Further, the colored portion may be constituted by a sheet itself such as a tape member colored with a pigment or the like, or may be constituted by a printing layer. On the other hand, in the present embodiment, the visually recognizable state is a state in which the illuminance (lx) can be visually recognized in an environment of 100 (lx) to 1000 (lx).

The absorbent article 10 of this embodiment has a tape colored portion 92 formed in the identification area RA. The tape member 60 has a base layer 66 and a printing layer 67 overlapping the base layer 66 in the thickness direction. The printing layer 67 constitutes the tape colored portion 92. The tape colored portion 92 constituted by the printing layer 67 is formed over the entire tape member 60. Accordingly, the identification area RA is formed over the entire tape member 60. On the other hand, as in Modification 1 described later, the identification area RA may be formed in a part of the tape member 60.

In addition, in the stretchable tape member 60, it is preferable not to form the printing layer 67 over the entire side edge along the extending direction D of the tape member 60. The area in which the printing layer is disposed and the area in which the printing layer is not disposed have different easiness of elongation when elongated because the substrate is affected by the printing ink, and the area in which the printing layer 67 is formed has different extensibility. Is lowered. Therefore, for example, if the printing layer 67 with partially deteriorated stretchability is disposed on the side edge along the stretching direction D of the tape member 60, cracks may occur on the side edge of the tape member 60. There is a risk of occurrence. In particular, the side edge along the elongation direction of the tape member 60 is liable to be applied with a force during elongation, and cracking is more likely to occur. However, by not forming the printed layer 67 over the entire side edge along the elongation direction D of the tape member 60, no difference in elongation due to the presence or absence of the printed layer 67 occurs, and cracks Can be suppressed.

The printing layer 67 may be disposed on the skin-facing surface side T1 of the base layer 66. Since the printed layer 67 is disposed on the skin-facing side T1 of the base layer 66, the printed layer 67 is not disposed toward the worn article when the absorbent article 10 is used, and It is arranged toward the seat 22. When using the absorbent article 10, it is possible to suppress that the worn article and the printing layer 67 are difficult to rub, and the printing layer 67 is unintentionally difficult to see.

The printing layer 67 may be configured to be visible through the base layer 66 from the non-skin side of the absorbent article. Suitably, the base layer 66 may be transparent or translucent. When the base layer 66 is transparent or translucent, it becomes easier to visually recognize the printing layer 67 through the base layer 66 from the non-skin facing surface side T2 of the absorbent article.

Further, in another aspect, the printing layer 67 may be disposed on the non-skin surface side T2 of the base layer 66. When the user visually recognizes the absorbent article 10 from the non-skin side (T2) of the absorbent article, the printing layer 67 can be visually recognized without passing through the base layer 66, and identification by the identification area RA It is easier to exert the effect.

The colored portion may be visually recognizable in the form of viewing through the body portion 20 from the skin-facing surface side T1 of the absorbent article 10. When using the absorbent article 10, the skin-facing surface of the body portion 20, that is, the surface sheet 21 is directed toward the wearer's body. Therefore, there are many opportunities for the user to visually recognize the surface of the body portion 20 facing the skin. Since the colored portion can be visually recognized from the skin-facing surface side T1, the user can recognize the presence of the tape member 60 at the time of wearing.

The colored portion can be visually recognized in the form viewed through the top sheet 21 and the back sheet 22 in the region where the absorbent core 23 is not disposed, and in the region where the absorbent core 23 is disposed, the surface It may be visible through the sheet 21, the back sheet 22, and the absorbent core 23. Preferably, the colored portion may be formed in a region that does not overlap the absorbent core 23. It may be visually recognizable in the form of viewing through the body portion 20 from the skin-facing surface side T1 of the absorbent article 10.

In addition, in the configuration in which the printing layer 67 is disposed on the skin-facing surface side of the base layer 66 as in the present embodiment, the base layer 66 is visually recognized from the skin-facing surface side T1 of the absorbent article. The printing layer 67 can be visually recognized without passing through, and the presence of the tape member 60 becomes easier to recognize when worn.

The identification area RA is formed all over the tape member 60 in a plan view, and is disposed in the gripping portion 65. Accordingly, the gripping portion 65 is easily conspicuous with respect to the region adjacent to the gripping portion 65. The user can easily recognize the gripping portion 65. The user can perform a smooth disposal operation by grasping the location to be held at the time of the disposal operation.

More preferably, the gripping portion 65 is conspicuous for an adjacent area adjacent to one end 60A of the tape member 60 and an adjacent area adjacent to the side edge 60B of the tape member 60 It can be easily organized. In both the adjacent area adjacent to one end 60A of the tape member 60 and the adjacent area adjacent to the side edge 60B of the tape member 60, the color difference with respect to the identification area RA is Δ3.0 It may be more than that. Since the color difference ΔE between the three adjacent regions and the gripping part 65 disposed surrounding the gripping part 65 on the non-skin-facing surface of the body part 20 is 3.0 or more, the user may select the gripping part 65 It becomes easier to recognize, and smooth disposal operation can be performed.

The identification region RA may be disposed outside the front-rear direction than the outer edge of the adhesive portions 70, 42, 52 in the front-rear direction. Suitably, the identification area RA may be disposed outside the front-rear direction than the outer edge of the main body adhesive portion 70 in the front-rear direction. The area where the adhesive portion is formed is fixed to the worn article when worn, and is difficult to be visually recognized from the side of the absorbent article facing the skin. On the other hand, the area outside the area in the front-rear direction than the area in which the adhesive portion is formed is not fixed to the worn article when worn, and the absorbent article is curled or floated, which may be visually recognized from the side facing the skin. Since the identification area is disposed outside the front-rear direction than the outer edge of the adhesive portion in the front-rear direction, the user can visually recognize the tape member 60 when wearing it, making it easier to recognize the presence of the tape member 60.

Next, an absorbent article according to another embodiment will be described. Incidentally, in the following description, the same reference numerals are used for the same places as in the above-described embodiment, and the description is omitted. FIG. 5 shows a part of the plane of the absorbent article 10A according to Modification Example 1 and the absorbent article 10B according to Modification Example 2 as viewed from the non-skin side.

Specifically, the identification area RA is disposed in the gripping portion 65 of the tape member 60. When operating the tape member 60, the user cannot grip and operate the fixing portion 62, and grip the gripping portion 65 to operate. More preferably, the user operates with one end 60A of the tape member (the end opposite to the fixing part). Since the user can easily recognize the gripping part 65, it is possible to smoothly hold the gripping part during operation and use the tape member 60 to cleanly dispose of the absorbent article.

As a configuration for making the gripping portion of the tape member more conspicuous, like the absorbent article 10A according to Modification Example 1, the tape colored portion 92 may be formed only in a region where the gripping portion 65 is disposed. In addition, like the absorbent article 10B according to Modification 2, the body coloring portion 91 is formed in the adjacent region RB adjacent to the gripping portion 65, and the gripping portion 65 of the tape member 60 The tape colored portion 92 may be formed in the other regions R3. In addition, in the absorbent article 10B according to Modification 2, the region R3 other than the gripping portion 65 of the tape member 60 is hardly conspicuous to the non-skin surface of the body portion 20, The gripping portion 65 may be easily conspicuous. Specifically, the color difference between the region R3 other than the gripping part of the tape member and the gripping part 65 (identification area RA) is between the region R3 other than the gripping part of the tape member and the adjacent region RB. It may be higher than the color difference. According to this configuration, the user can grasp not only the target member (tape member) to perform the operation, but also a portion of the target member to perform the operation. The user can perform the disposal operation smoothly by grasping the location to be held at the time of the disposal operation.

Next, the absorbent article according to Modification Examples 3 and 4 will be described based on FIG. 6. 6 shows a part of the plane of the absorbent article 10C according to Modification Example 3 and the absorbent article 10D according to Modification Example 4 as viewed from the non-skin surface side T2. 6(A) shows the absorbent article 10C according to the modified example 3, and FIG. 6(B) shows the absorbent article 10D according to the modified example 4.

In the absorbent article 10C according to Modification 3 and the absorbent article 10D according to Modification 4, the identification area RA is not disposed over the entire tape member 60, and is identified in a part of the tape member 60 Area RA is arranged. A tape colored portion 92 is formed in the identification area RA. The tape colored portion 92 may have a guide portion 95 that guides the operation of the tape member 60. The guide portion 95 may be used to guide the operation of the tape member 60. Specifically, in the absorbent article used by stretching the tape member 60, an arrow indicating the direction in which the tape member 60 is stretched may be used as in the absorbent article 10C according to the third modification. In addition, in the absorbent article using the tape member 60 in an elongated state, like the absorbent article 10D according to Modification Example 4, the character ``stretches'' indicating that the tape member 60 has an elongation property. As an example, the tape member 60 may be configured to prompt the user to elongate the tape member 60.

Moreover, the colored part may comprise only the guide part 95, and may have a part other than the guide part 95. The tape colored portion 92 according to Modification Example 4 may have a guide portion 95 and a background portion 96. By having the guide part 95 and the background part 96, the guide part 95 can be made more conspicuous, and smooth operation can be urged.
