Here, the outer portion in the present invention is a portion occupying a certain range in the width direction W including the edge in the width direction W, and the outer edge is the edge in the width direction W. In addition, the overlapping state of the present invention refers to a state in which one member overlaps the other member in plan view, that is, a state in which the other member is arranged on the skin surface side or the non-skin surface side of one member. The overlapping state includes not only a state in which one member and the other member are in contact with each other, but also a structure in which another member is interposed between the one member and the other member.

The release sheet 40 is disposed on the non-skin surface side T2 of the main body portion 2 in a packaged state to be described later, and covers the adhesive portion 27 . The release sheet 40 is constituted in a state before use of the absorbent article 1 , and covers the adhesive portion 27 to prevent deterioration of the adhesive portion 27 . The release sheet 40 is separated from the absorbent article 1 at the time of use. The "peeling sheet" in the present invention is a peeling sheet arranged on the non-skin surface side T2 of the main body portion 2 . The body portion having the wings and the hip wings includes a wing joint portion for joining the wings to the wearing article, and a hip wing joint portion for joining the hip wings to the wearing article. The flap release sheet covering the flap joint portion and the hip flap release sheet covering the hip flap joint portion are positioned on the skin side than the body portion 2 in the packaged state, and do not constitute the "release sheet" of the present invention. The release sheet 40 is arranged between the main body 2 and the packaging sheet 70 . The release sheet 40 may be located in the region where the absorber 23 is arranged in a plan view. In other words, at least a part of the absorber 23 may extend outward from the release sheet 40 in plan view. The release sheet 40 is provided with a release coloring portion 81 . The structure of the peeling coloring part 81 will be described in detail later. The outer edge 40E in the width direction W of the release sheet 40 may extend along the front-rear direction L. The peeling sheet 40 may have a rectangular shape surrounded by four sides.

The wrapping sheet 70 wraps the main body 2 individually. The packaging sheet 70 is arranged on the non-skin surface side T2 rather than the release sheet 40 . The packaging sheet 70 may be formed of a nonwoven fabric or a film. As shown in FIG. 3 and the like, the release sheet 40 and the packaging sheet 70 are joined via the sheet joining portion 45 . The sheet joint portion 45 may be a portion to which an adhesive is added.

From the unfolded state shown in FIGS. 1 and 2 , the absorbent article 1 may be folded a plurality of times on the basis of the crease extending in the width direction W to be in a packaged state. The packaged state is a state in which the main body 2 is individually packaged by the packaging sheet 70 after being folded multiple times on the basis of the folds extending in the width direction W. As shown in FIG. The plurality of folds may have a first broad fold FW1 and a second broad fold FW2 extending in the width direction W. The first broad fold FW1 and the second broad fold FW2 may be separated in the front-rear direction L. The first broadside crease FW1 may be positioned more rearward than the second broadside crease FW2, and may constitute the boundary between the rear side region S3 and the central region S2. The second broadside crease FW2 may constitute a boundary between the front side region S1 and the center region S2. In addition, the absorbent article 1 is folded together in a state where the main body portion 2 is arranged on the packaging sheet 70 and the release sheet 40 . As an example of the folded state, the expanded state (the state shown in FIGS. 1 and 2 ) of the main body portion 2 is arranged on the packaging sheet 70 and the release sheet 40, and the absorbency is adjusted based on the first broadside fold FW1. The rear end edge of the article 1 is folded inward in the front-rear direction L. Next, the front end edge side of the absorbent article 1 is folded inward in the front-rear direction L on the basis of the second broadside crease FW2. Next, the outer edge 70F of the packaging sheet 70 arranged on the outer surface of the absorbent article 1 is joined to the packaging sheet 70 overlapping the outer edge 70F of the packaging sheet 70 by the tape member 75 . That is, the tape member 75 joins the outer edge 70F of the packaging sheet 70 arranged on the outer surface of the absorbent article 1 to the packaging sheet 70 overlapping the outer edge 70F of the packaging sheet 70 in the packaging state. In addition, in a modification, the belt piece member 75 may not be provided. In addition, in the modified example, the absorbent article 1 may be folded based on the folds extending in the front-rear direction, or the folds extending in the width direction W may be folded in addition to the first broad fold FW1 and the second broad fold. In addition to the crease FW2, there are crease lines other than the third broadside crease and the like.

The absorbent article 1 of the present embodiment is configured so that the user can easily recognize the area where the release sheet 40 is arranged and the area where the release sheet 40 is not arranged, and the positional shift of the colored release sheet 40 is less conspicuous. . The positional shift includes not only the positional shift in the width direction W of the release sheet, etc., but also the angular shift. Although the size of the positional deviation is not particularly limited, for example, the deviation due to individual differences may be 10 mm or less. Although the numerical value of the deviation of the angle is not particularly limited, for example, the deviation due to individual differences may be 15 degrees or less. The offset of the peeling sheet may be formed inadvertently in the manufacturing process or may be formed intentionally. In the production process of the release sheet, in a state where the adhesive portion 27 is added, it is often merged with the back sheet 22 . In this form, since the peeling sheet is shifted, the adhesive portion 27 is also shifted and arranged. For example, the angle of the adhesive portion 27 is also arranged to be inclined with respect to the front-rear direction L due to the positional shift of the peeling sheet. Thereby, the peeling sheet becomes easy to peel, and the workability can be improved. Next, the structure of the absorbent article 1 which achieves this effect will be described in detail. As shown in FIG. 3 etc., the absorbent article 1 has the absorption coloring part 82 provided in at least the non-skin surface of the absorber 23, and the peeling coloring part 81 provided in the peeling sheet 40 and having the same color as the absorption coloring part 82. The peeling colored portion 81 may be a portion printed on the peeling sheet 40, or may be a portion colored by the peeling sheet 40 itself with a pigment or the like. The peeling colored portion 81 is configured to be visible from at least the non-skin surface of the peeling sheet 40 . The absorption coloring part 82 should just be provided in at least the non-skin surface of the absorber 23, and may be provided in the skin surface of the absorber 23. The absorption coloring part 82 may be a part printed on at least one of the absorption core and the core clad layer, or may be a part colored by a pigment or the like in the absorption core or the like. Here, the same color can be a color with a color difference ΔE of 20.0 or less, and more preferably, a color difference ΔE of 12.0 or less. The color difference ΔE is measured at two points (two areas) to be measured using a commercially available colorimeter, and compared and quantified in accordance with the CIE1976 (L*a*b*) color space specified in JIS Z 8729 The latter value can be obtained from this. Specifically, when the difference in L* value between two points to be measured is ΔL*, the difference in a* is Δa*, and the difference in b* value is Δb*, the color difference ΔE=[(ΔL*) ² +(Δa*) ² +(Δb*) ² ] ^1/2 to find. This embodiment is the color difference measured from the non-skin surface side of an absorbent article in the state of an absorbent article. The evaluation of whether different colors are the same color will be described later. In addition, the peeling coloring part 81 and the absorption coloring part 82 may be a color other than the white tone. Here, as for the color of the white base tone, ΔL in the (L*a*b**) color space may be 4.0 or less with respect to the white reference plate (L96.76 a+0.44 b+2.17). In addition, in the form in which the peeling coloring part 81 and the absorption coloring part 82 have a plurality of colors, any one of the colors may be the same color. That is, any color of the peeling coloring portion 81 may be the same color as any color of the absorption coloring portion 82 .

The light transmittance of the back sheet 22 is 45% or more. Since the light transmittance of the back sheet 22 is 45% or more, when the user views the absorbent article 1 from the non-skin surface side T2 , the absorbing colored portion 82 can be visually recognized through the back sheet 22 . Therefore, by peeling off the colored portion 81, the peeling sheet 40 can be made conspicuous, the user can grasp the existence and position of the peeling sheet 40, and the operability can be improved. The offset is less noticeable. In addition, a sheet with a light transmittance of 30% is in a state in which objects on the back side can be seen even slightly through the sheet, and a sheet with a light transmittance of 45% is in a state where objects on the back side can be clearly seen through the sheet. status. In addition, "visible recognition" in this work refers to a room (standard: 500~750 lx (lux) that is brightly lit with neutral white (color temperature standard 4600~5400 K (Kelvin)) )), at a distance of about 30~50cm, the subjects with good visual acuity (above 1.0) in both eyes can recognize the object when they see the object. The evaluation of visibility due to the difference in light transmittance will be described later. In addition, it is desirable that the light transmittance of the packaging sheet 70 and the back sheet 22 should be 45% or more in a state where the packaging sheet 70 and the back sheet 22 are overlapped. According to this aspect, when the user visually recognizes the absorbent article 1 from the non-skin surface side T2 , it becomes possible to visually recognize the absorbing colored portion 82 through the packaging sheet 70 and the back sheet 22 . Ideally, the light transmittance of the release sheet 40 and the back sheet 22 should be 45% or more in a state where the release sheet 40 and the packaging sheet 70 are stacked. According to this aspect, when the user visually recognizes the absorbent article 1 from the non-skin surface side T2 , it becomes possible to visually recognize the absorption colored portion 82 through the release sheet 40 and the back sheet 22 . More preferably, the light transmittance of the packaging sheet 70 , the release sheet 40 and the back sheet 22 may be 45% or more in a state where the packaging sheet 70 , the release sheet 40 and the back sheet 22 are stacked. According to this aspect, when the user visually recognizes the absorbent article 1 from the non-skin surface side T2 , it becomes possible to visually recognize the absorption colored portion 82 through the packaging sheet 70 , the release sheet 40 , and the back sheet 22 .

Here, "light transmittance" is measured according to JIS K7105-7136. The light transmittance can be measured using, for example, a haze meter (model NDH700P2) manufactured by Nippon Denshoku Kogyo Co., Ltd. The measuring sensor is a circle with a diameter of 20 mm. When the area to be measured is larger than the measurement sensor, the measurement is performed directly in this way. When the area to be measured is smaller than the sensor, for example, a hole with a diameter of 20 mm or less is opened on a sample with a transmittance of 0%, and the hole is fixed anywhere in the sensor. Furthermore, the area to be measured is set in the hole to measure the transmittance. For comparison with the transmittance of no sample, the transmittance of no sample was set as 100, and the transmittance of the area was converted.

The absorption coloring portion 82 is arranged across the outer edge 40E of the release sheet 40 . Therefore, the absorption coloring part 82 is arranged on the skin surface side T1 of the outer edge 40E of the release sheet 40 and extends from the outer edge 40E of the release sheet 40 to both the outer and inner sides in the width direction W. The absorption coloring portion 82 only needs to span at least a part of the outer edge 40E of the release sheet 40 , and may span the entire area in the front-rear direction L of the outer edge 40E of the release sheet 40 . The absorption coloring part 82 may be provided in the whole area of the absorber 23 in a plan view, or may be provided only in a region spanning the outer edge 40E of the release sheet 40 . Preferably, the absorbent coloring portion 82 is disposed on the outer surface of the absorbent article 1 in the packaged state, and more specifically, in the region between the first broadside fold FW1 and the second broadside fold FW2. , the absorption coloring portion 82 may span the entire area of the outer edge 40E of the release sheet 40 .

The outer edge 40E in the width direction of the release sheet 40 extends along the front-rear direction L. As shown in FIG. For example, in a state in which the release sheet 40 is inclined with respect to the main body portion 2 , deviations such as the inclination of the release sheet 40 of the entire absorbent article 1 are easy with respect to the outer edge of the release sheet 40 extending in the front-rear direction L as a reference. become conspicuous. However, since the absorbing coloring portion 82 of the same color as the peeling coloring portion 81 is arranged across the outer edge 40E of the release sheet 40, the outer edge 40E of the release sheet 40 becomes less conspicuous due to the absorbing coloring portion 82, and the absorbent article Displacement such as the inclination of the entire release sheet 40 becomes less conspicuous. Therefore, the uniformity of the shape of the entire absorbent article 1 is realized, the shapeability is improved, and the misidentification of product failure due to the positional deviation of the release sheet 40 can be suppressed. Moreover, when the user sees the absorbent article 1 from the non-skin surface side T2, the presence and area of the absorber 23 can be grasped by the absorption colored portion 82. By grasping the presence and area of the absorber 23, the user can grasp the absorption performance and obtain a sense of security against leakage of bodily fluids.

The release sheet 40 should just have the background part 42 in which the release coloring part 81 is not provided. That is, the peeling colored portion 81 may be provided on a part of the non-skin surface of the peeling sheet 40 . The light transmittance of the background portion 42 may be 30% or more. Since the light transmittance of the background portion 42 is 30% or more, when the user views the absorbent article 1 from the non-skin surface side T2 of the absorbent article 1 , the presence of the absorbing colored portion 82 can be grasped through the background portion 42 . Therefore, when the user sees the absorbent article 1 from the non-skin surface side T2 of the absorbent article 1, the peeling colored portion 81 and the absorbing colored portion 82 visible through the background portion 42 are integrated, and the entire peeling sheet 40 is integrated. As integration, the release sheet 40 and the absorber 23 can be easily integrated. Therefore, the deviation, such as the inclination of the release sheet 40 of the whole absorbent article 1, becomes less conspicuous. It is preferable that the light transmittance of the background portion 42 is higher than that of the peeling coloring portion 81 .

According to this structure, the whole absorption core which absorbs a bodily fluid can be made conspicuous, and a user can grasp|ascertain the existence and the area|region of an absorption core by absorbing a colored part. The user can grasp the absorption performance and obtain a sense of security against leakage of bodily fluids. The structure in which the absorption coloring part is provided in the absorbent core may be constituted by partially performing the bleaching process of the absorbent material. The absorption colored part may be caused by the color development of the carbonyl group or quinoid structure of the existing lignin without the bleaching process. In other configurations in which the absorbent core is provided with an absorbent coloring portion, coloring may be applied to the bleached absorbent material, and natural extraction portions such as catechins and tannins may be applied; natural products such as tea leaves may also be applied. . Suitable color function can be imparted by coloring with natural extracts and natural products. Moreover, in an absorbent article having functional materials such as a cooling agent and an antibacterial agent, the function can be emphasized by color. For example, an absorbent article to which catechin is imparted is colored green, and tea (catechin) can also be thought of in terms of color, and an absorbent article imparted with a natural ingredient is colored brown, and Natural (wood) can be thought of by color. Moreover, in the form in which the absorption coloring part is provided in the absorption core, it is preferable to use the light transmittance in the range of 30% or more and 95% in at least one of the surface sheet and the back sheet. By using the surface sheet or the back sheet within this numerical range, a sense of security before absorbing can be obtained, and after absorbing, it becomes easy to judge where the absorbent core has absorbed, so it is easy to obtain a sense of security without leakage after use.

(4) Sensory evaluation Next, the evaluation of whether different colors are the same color will be described. Using the samples of Example 1, Example 2, Comparative Example 1, and Comparative Example 2, evaluation of whether or not they were the same color was performed. The color difference of each sample is measured by connecting the measuring machine from the non-skin side of the sample. In the evaluation, an absorbent article having an absorption coloring part and a peeling coloring part was visually recognized from the non-skin surface side, and six testers evaluated whether the absorption coloring part and the peeling coloring part could be regarded as the same color. Experimenters 1 to 3 were male and experimenters 4 to 6 were female. The evaluation is in a room (standard: 500~750 lx (lux)) brightly lit with neutral white (color temperature standard 4600~5400 K (Kelvin)), in about 30~50cm Distance, evaluation by 6 subjects with good visual acuity (1.0 or more) in both eyes in 3 stages. When it was judged to be the same color, it was evaluated as "0", when it was judged to be barely the same color, it was evaluated as "△", and when it was judged as different colors, it was evaluated as "X". Table 1 shows the evaluation results. As shown in Table 1, in Example 1, Example 2, and Example 3, since the same color can be determined, it can be seen that the color difference ΔE should be 20.0 or less. In addition, it can be seen that when the color difference ΔE of different colors is 12.0 or less, it is clearly recognized as the same color, and it is more suitable that the color difference ΔE is 12.0 or less.

Next, the evaluation of the viewing method based on the light transmittance will be described in detail. Using the samples of Example 1, Example 2, Comparative Example 1, and Comparative Example 2, it was evaluated whether or not the colored portion could be visually recognized through the back sheet. The absorbent article having the absorption coloring part was observed from the non-skin surface side (the state in which the peeling sheet was removed), and the evaluation of whether or not the absorption coloring part could be visually recognized through the back sheet was performed by 6 testers. Experimenters 1 to 3 were male and experimenters 4 to 6 were female. The evaluation is in a room (standard: 500~750 lx (lux)) brightly lit with neutral white (color temperature standard 4600~5400 K (Kelvin)), in about 30~50cm The distance was performed by 6 subjects with good visual acuity (1.0 or more) in both eyes. The evaluation is carried out in 2 stages. When the absorption coloring part on the back side was clearly visually recognized through the back sheet, it was evaluated as "0", and when it was judged to be barely visible, it was evaluated as "△". Even in any one of Examples 1 to 4, it was found that it was evaluated as a visible absorption colored portion, and the light transmittance of the back sheet should just be 30% or more. In addition, more suitable results were obtained in Examples 1 and 3, and it was found that the light transmittance of the back sheet was preferably 45% or more.

As mentioned above, although this invention was demonstrated in detail using the above-mentioned embodiment, it is obvious to this manufacturer that this invention is not limited by the embodiment described in this specification. This creation can be implemented as revisions and changes without departing from the meaning and scope of this creation determined by the description of the patent scope of the new application. Therefore, what is described in this specification is intended for illustration and description, and does not intend to limit the present invention at all.
