Detailed Description

(1) Brief description of the embodiments

One aspect relates to an absorbent article comprising: a front-back direction and a width direction orthogonal to each other; a front waistline region, a rear waistline region, and a crotch region disposed between the front waistline region and the rear waistline region; an absorbent core; and an indicator disposed at least in the crotch region and discolored by contact with moisture on a non-skin-facing side of the absorbent core, wherein the indicator has an indicator row extending in the front-back direction, and the indicator row is formed of an aggregate of a plurality of pattern portions disposed at intervals in the front-back direction.

The indicating portion row extends in the front-rear direction, and the assistant can grasp the range of the urination region in the front-rear direction through the indicating portion row, and can grasp the urination position and the approximate urination amount in the front-rear direction. The plurality of pattern portions are arranged at intervals in the front-rear direction on the indicator portion row. The respective pattern portions are easily noticeable as compared with the line shape. The assistant can recognize each pattern portion as an independent mark, and can grasp a precise urination amount and urination position with the pattern portion as a scale. Therefore, the assistant can grasp the health state and wearing state of the wearer according to the urination state.

According to a preferred aspect, the pattern part may have: a first pattern section; and a second pattern part which is discolored by contact with moisture and is visually different from the first pattern part. Since the first pattern part and the second pattern part are visually different from each other, the pattern parts are easily distinguished from each other. The assistant can easily grasp the position of each pattern portion in the indication portion row, and can grasp the urination amount and the urination position more appropriately using the pattern portion as a scale.

According to a preferred aspect, the first pattern part and the second pattern part may be interactively related. Since the first pattern portion is cross-correlated with the second pattern portion, it is easy for the assistant to recognize both the first pattern portion and the second pattern portion as the pattern portion representing the scale. Therefore, the urination amount and the urination position can be grasped more appropriately by using the whole including the first pattern portion and the second pattern portion as a scale.

According to a preferred aspect, the first pattern part and the second pattern part may be interactively unrelated. Since the pattern portions are not related to each other, the assistant distinguishes the pattern portions from each other to recognize the pattern portions, and the pattern portions are not easily confused. Therefore, the assistant can easily grasp the reaction state of the indicating portion and grasp the urine output properly.

According to a preferred aspect, at least one of the second pattern portions may be disposed between the first pattern portions in the front-rear direction. The assistant can grasp urination not only from the first pattern portion but also from the second pattern portion, and can grasp the urination more finely.

According to a preferred aspect, the maximum length of the first pattern part may be longer than the maximum length of the second pattern part. The first pattern portion is more noticeable than the second pattern portion, and the pattern portion easily functions as a scale for identifying the urine discharge amount. Further, since the maximum length of the second pattern portion is short, the second pattern portion functions as a fine scale, and the urination can be grasped more finely.

According to a preferred aspect, the first pattern part and the second pattern part may be alternately arranged at intervals in the front-rear direction, and the interval between the first pattern part and the second pattern part in the front-rear direction may be 5mm or less. Since the first pattern part and the second pattern part are alternately arranged, the respective pattern parts are easy to attract attention, and the urination condition can be easily grasped from the pattern parts. In addition, the interval between the first pattern part and the second pattern part is less than 5mm, so that the first pattern part and the second pattern part are easy to compare, whether each pattern part is discolored or not is easy to grasp, the discoloring range of the pattern part is easy to grasp, and the urination condition is easy to grasp more finely.

According to a preferred aspect, the maximum length in the front-rear direction of the pattern portions may be longer than the interval in the front-rear direction between the pattern portions. The pattern portions are relatively long in the front-rear direction, and the individual pattern portions are likely to be noticeable and to function as a scale. Further, since the pattern portions have a long length in the front-rear direction, it is possible to grasp not only whether each pattern portion is discolored but also a discolored range of the pattern portion (for example, a half area of one pattern portion is discolored), and it is easy to grasp urination more finely.

According to a preferred aspect, the pitch of the pattern portion in the front-rear direction may be constant. According to this structure, the pattern portion more easily functions as a scale for marking the urine output.

According to a preferred aspect, the interval between the pattern parts may be constant. According to this structure, the pattern portion more easily functions as a scale for marking the urine output.

According to a preferred aspect, the pattern portions may be connected to each other via a connecting portion constituting the indicator row. The indicator row constituted by the pattern portion is easily recognized as an integrated row by the connecting portion, and the assistant easily grasps the urination position with respect to the entire indicator row.

According to a preferred aspect, the pattern portion may be surrounded by surrounding portions constituting the indicating portion column. By surrounding the pattern portions with the surrounding portions, each pattern portion can be made noticeable. The assistant can easily grasp the position of each pattern portion in the indication portion row, and can grasp the urination amount and the urination position more appropriately using the pattern portion as a scale.

According to a preferred aspect, absorbent concave portions in which the absorbent core is concave in the thickness direction may be formed on both sides of the indicator row in the width direction, respectively, the absorbent concave portions extending in the front-rear direction. The body fluid excreted from the excretory opening spreads from the opposing portions in the front-rear direction and the width direction in a circle center shape. Therefore, even if the indicator portion row is disposed to face the excretion portion, if the body fluid is excessively diffused in the width direction, the body fluid is not diffused in the front-rear direction in which the indicator portion row extends, the indicator portion row is not discolored, and the urination state cannot be accurately grasped. By disposing the absorbing recesses on both sides in the width direction of the indicator portion row, when the body fluid is discharged to a position facing the indicator portion row, the body fluid can be prevented from spreading outward in the width direction by the absorbing recesses on both sides, the body fluid can be spread along the indicator portion row, and the urination state can be grasped more accurately by the indicator portion row.

According to a preferred aspect, the absorbent concave portion may be a slit penetrating the absorbent core in a thickness direction, and sheets arranged with the absorbent core interposed therebetween in the thickness direction may be joined to each other in a region overlapping the slit in a plan view. By both the slit and the portion where the sheet is joined to each other, the body fluid can be prevented from spreading to the outside in the width direction of the slit, the body fluid can be spread along the indicator row, and the excretion can be grasped more accurately by the indicator row.

According to a preferred aspect, the indicator array may be disposed at a center in a width direction of the absorbent article, the indicator may include a pair of auxiliary indicators disposed on both sides in the width direction of the indicator array, and the auxiliary indicators may be disposed on an outer side in the width direction of the absorbent article than the absorbent concave portion. The auxiliary indication portion can indicate that the body fluid has spread outward in the width direction over the absorption concave portion. Therefore, when the urination amount is large or the wearing position is shifted, the assisting person can appropriately grasp the urination state by the assisting instruction section, and can suppress side leakage.

According to a preferred aspect, the indicator row may be disposed at a center in a width direction of the absorbent article, and the indicator may include a pair of auxiliary indicators disposed on both sides of the indicator row in the width direction. According to this configuration, the indicator arranged in a plurality of rows can grasp the spreading of urine in the front-rear direction.

According to a preferred aspect, the plurality of pattern portions arranged side by side in the front-rear direction may indicate urination in stages. According to this configuration, urination can be indicated in stages by the pattern portion, and the pattern portion can more easily function as a scale.

According to a preferred aspect, the pattern portions may include numbers, and the pattern portions including the numbers may be arranged side by side in the front-rear direction. According to this configuration, urination can be easily and simply represented in stages by numerals, and the pattern portion can more easily function as a scale.

According to a preferred aspect, the pattern portion may include patterns that change stepwise, and the pattern portions including the patterns may be arranged side by side in the front-rear direction. According to this configuration, urination can be easily and simply represented in stages by the pattern, and the pattern portion can more easily function as a scale.

According to a preferred aspect, the indicator row is provided with a low visibility portion having a low visibility after color change and a high visibility portion having a higher visibility than the low visibility portion, the high visibility portion being located on both sides in the front-rear direction with the low visibility portion interposed therebetween, and when the sum of the lengths of the overlapping portions of a virtual straight line passing through an arbitrary portion of the indicator row in the width direction and the indicator row is defined as the application width of the color-changing agent at the portion, the application width of the low visibility portion is smaller than that of the high visibility portions located on both sides in the front-rear direction. By providing the low visibility portion, the presence or absence of the discoloration of the color-changing agent application portion and the degree of expansion of the discoloration portion (the position of the excreted liquid) can be easily and accurately confirmed, as compared with a case where the color-changing agent application portion is continuous in the front-rear direction with the same width (the length in the width direction is constant).

An absorbent article container according to one aspect of the present invention is an absorbent article container in which a plurality of the absorbent articles are accommodated, the plurality of absorbent articles including: a first absorbent article having a first decorative portion; and a second absorbent article having a second decorative portion visually different from the first decorative portion, wherein a distance between a center position of the pattern portion of the first absorbent article and a center position of the pattern portion of the second absorbent article in the front-rear direction is 10% or less with respect to a length of the pattern portion, and a distance between the center position of the pattern portion of the first absorbent article and a center position of the pattern portion of the second absorbent article in the width direction is 10% or less with respect to the length of the pattern portion.

Since the first decorative portion is different from the second decorative portion, a plurality of types of absorbent articles can be housed in one housing, and the decorativeness can be improved. In addition, since the center positions of the pattern portions are substantially the same in the first absorbent article and the second absorbent article, the urination state can be expressed in the same manner in any absorbent article while achieving different decorativeness. The assistant can similarly grasp urination even when using absorbent articles having different designs.

According to a preferred aspect, the pattern portion of the first absorbent article and the pattern portion of the second absorbent article may be visually the same. Since the pattern portions are visually the same, even if absorbent articles having different designs of the decorative portions are used, urination can be grasped in the same manner.

According to a preferred aspect, the pattern portion of the first absorbent article and the pattern portion of the second absorbent article may be visually different. The first decorative portion and the second decorative portion can also be provided with different decorative properties by the pattern portion. Even if the pattern portions are visually different, the center positions of the pattern portions are the same, and therefore, the pattern portions can function as a scale.

According to a preferred aspect, the first decorative portion and the second decorative portion are recognizable from a non-skin surface side of the absorbent article. The assistant can recognize the first decorative part, the second decorative part and the pattern part when the assistant recognizes the absorbent article from the non-skin surface side. The indicator can simultaneously exert different decorative effects of the decorative part and the index of urination based on the indicating part.

Therefore, specific dimensions and the like should be determined with reference to the following description. Further, the drawings may include portions having different dimensional relationships and ratios from each other.

Fig. 1 is a schematic plan view of an absorbent article according to an embodiment as viewed from the skin surface side, and fig. 2 is a schematic plan view of the absorbent article as viewed from the non-skin surface side. Fig. 3 is a schematic sectional view taken along the section 3A-3A of the absorbent article shown in fig. 1. Fig. 1 to 3 show the absorbent article in an extended state. In the cross-sectional view shown in fig. 3, the respective members are shown separately in the thickness direction T for convenience of explanation, while in an actual product, they are connected in the thickness direction T. The extended state in the present invention means a state in which the absorbent article 10 is extended without forming wrinkles. The natural state in the present invention means a state in which the absorbent article 10 contained in the package is taken out of the package and left to stand in an atmosphere of 20 ℃ ± 2 ℃ and a relative humidity of 60% ± 5% RH for 24 hours.

The absorbent article 10 has a front-back direction L, a width direction W, and a thickness direction T. The front-back direction L is a direction connecting the abdomen side and the back side of the absorbent article 10 in a worn state. The width direction W is a direction orthogonal to the front-rear direction L in a plan view of the absorbent article 10. The thickness direction T is a direction orthogonal to both the front-rear direction L and the width direction W. The non-skin surface or non-skin surface side T2 is a surface or side facing the opposite side of the skin of the wearer in the worn state of the absorbent article. On the other hand, the skin surface or skin surface side T1 is a surface or side facing the skin of the wearer in the worn state of the absorbent article.

The absorbent article 10 has a front waistline region S1, a crotch region S3, and a rear waistline region S2. The front waistline region S1 is a region of the front waistline that faces the wearer when the absorbent article is used. The rear waist region S2 is a region that faces the rear waist of the wearer when the absorbent article is used. The crotch region S3 is a region located in the crotch of the wearer when the absorbent article is used, and is located between the front waistline region S1 and the rear waistline region S2. The crotch region S3 is a region provided with leg hole openings 65 arranged around the legs of the wearer. The leg hole openings 65 are portions recessed inward in the width direction from the outer edge of the absorbent article.

The absorbent article 10 includes an absorbent core 31 containing an absorbent material. The absorbent core 31 contains an absorbent material such as ground pulp or Super Absorbent Polymer (SAP), or a mixture thereof. The absorbent core 31 may be covered by a core cladding 32. The absorbent body 30 may be constituted by an absorbent core 31 and a core wrap 32. The core wrap 32 may be made of thin paper and disposed on the skin surface side T1 with respect to the absorbent core 31 and on the non-skin surface side T2 with respect to the absorbent core 31.

The absorbent core 31 is formed with absorbent depressions 41 depressed in the thickness direction. The absorbent concave 41 is formed of at least one of a slit penetrating the absorbent core 31 in the thickness direction, a low grammage portion of the absorbent material having a low grammage, and an embossed portion compressing the absorbent core and the like in the thickness direction. As shown in fig. 3, the absorbent concave portion 41 of the present embodiment is constituted by a slit formed in the absorbent core.

The absorbing recesses 41 extend in the front-rear direction L and are arranged at intervals in the width direction W. The absorbent concave 41 may be arranged not at the center of the absorbent core 31 in the width direction W but at both sides of the absorbent core 31 with respect to the center in the width direction W. By disposing the absorption concave portion, when the body fluid is discharged, the body fluid can be diffused in the front-rear direction by the absorption concave portion 41.

As shown in fig. 1 and 3, a topsheet 21 and a side sheet 22 may be provided on the skin-surface side T1 of the absorbent body 30 including the absorbent core 31. The topsheet 21 may be disposed across the center of the absorbent member 30 in the width direction W. The side sheet 22 may be configured to cover an outer side portion of the surface sheet 21. The top sheet 21 and the side sheet 22 may be made of a liquid-permeable sheet such as nonwoven fabric or perforated plastic film. The inner side portions of the side sheets 22 may be folded back to be overlapped. Between the overlapped side sheets 22, a leakage-preventing stretchable portion 43 stretchable in the front-rear direction L may be provided. The leakage preventing stretchable portion 43 may be formed of a rubber thread stretchable in the front-rear direction L. The side sheet 22 and the leakage-preventing stretchable portion 43 constitute leakage-preventing gathers standing on the skin surface side T1 when worn.

The back sheet 23 and the outer sheet 24 may be provided on the non-skin surface side T2 of the absorbent body 30. The outer sheet 24 may be provided on the non-skin surface side T2 of the back sheet 23. The length of the back sheet 23 in the width direction W is shorter than the length of the outer sheet 24 in the width direction W, and the length of the back sheet 23 in the front-rear direction L is shorter than the length of the outer sheet 24 in the front-rear direction L. The back sheet 23 may be composed of a liquid impermeable film. The exterior sheet 24 may be made of a liquid-permeable nonwoven fabric.

A fastening tape 90 is provided on the outer side of the rear waistline region S2. The hook and loop fastener 90 has a base 92 and a coupling portion 93. The base portion 92 is disposed between the exterior sheet 24 and the side sheet 22 in the thickness direction T, and extends outward from the exterior sheet 24 and the side sheet 22 in the width direction W. The coupling portion 93 is disposed on the base portion 92 and coupled to the target portion 95. The target portions 95 are disposed at intervals in the width direction in the front waistline region S1, and the coupling portions 93 of the hook and loop fastener 90 are respectively fixed thereto.

The absorbent article 10 has an indicator 70 that changes color when contacted by moisture. The indicator 70 is disposed so as to change color when the absorbent core 31 absorbs bodily fluids, and can recognize the absorption state of bodily fluids from the non-skin surface side T2 of the absorbent article 10. The indicator 70 has an indicator row extending in the front-rear direction L. The indicator row may extend at least in the front-rear direction L, may extend in both the front-rear direction and the width direction, and may be curved or linear.

The indicator 70 may be provided in at least the crotch region S3, in the front waistline region S1, or in the rear waistline region S2. The indicator 70 may be disposed on the non-skin surface side of the absorbent core 31, and may be provided on the back sheet 23 or the outer sheet 24. Preferably, the indicator 70 may be provided on the back sheet 23.

The indicator row may include a center indicator row 71 disposed at the center of the absorbent article 10 in the width direction W, and a pair of side indicator rows 72 disposed on both sides of the center indicator row 71 in the width direction W. The center indicator row 71 and the side indicator row 72 may be arranged at intervals in the width direction W. The center indicator row 71 may be arranged so as to straddle the center of the absorbent article 10 in the width direction W, and a part of the center indicator row 71 may be arranged away from the center of the absorbent article 10 in the width direction W. The indicator 70 arranged in a plurality of rows makes it possible to grasp the spreading of urine in the front-rear direction.

The center indicator row 71 and the side indicator row 72 are formed of an aggregate of a plurality of pattern portions 80 arranged at intervals in the front-rear direction L. The center indicating portion row 71 extends in the front-rear direction L, and the assistant can grasp the range of the urination region in the front-rear direction L through the center indicating portion row 71, and can grasp the urination position and the approximate urination amount in the front-rear direction L. A plurality of pattern portions 80 are arranged at intervals in the front-rear direction L in the center indication portion row 71 and the side indication portion row 72. The respective pattern portions 80 are easily noticeable as compared with the line shape. The assistant can recognize each pattern portion as an independent mark and grasp a precise urination amount and urination position with the pattern portion 80 as a scale. Therefore, the assistant can grasp the health state and wearing state of the wearer according to the urination state.

The center indicator row 71 and the side indicator row 72 in the present embodiment are formed of an aggregate of a plurality of pattern portions. However, in the modified example, one of the center indicator row 71 and the side indicator row may be formed of a linear or curved line instead of the aggregate of the patterns. The side indicating part row 72 constitutes an auxiliary indicating part. In the following description, the pattern portion of the center indicator row is mainly described, but the pattern structure of the center indicator row may be used for the side indicator row.

The center indicator row 71 and the side indicator row 72 may be configured to be visually different after being discolored by contact with moisture. Since the center indicator row 71 and the side indicator row 72 after color change are visually different from each other, the assistant can distinguish the center indicator row 71 and the side indicator row 72. Therefore, even when the entire indicating portions cannot be recognized, the assistant can appropriately grasp the reaction state of the indicating portions 70, such as a state in which only the center indicating portion row 71 has reacted, a state in which only the side indicating portions 72 have reacted, or a state in which a portion of the center indicating portion row 71 has reacted. Therefore, it is easy to grasp the urine output properly, and the absorbent article can be replaced at a proper timing. The center indicator column 71 and the side indicator column 72 may be arranged so as to be visually different before being changed in color. The indicator 70 shown in fig. 2, 4 and 5 shows a state after color change.

Here, "visually different" means that at least one of the size (length in the front-back direction and length in the width direction), shape, color, and density is different, and the structure may be visually recognized as different, not by touch. After the color change, the center indicator portion row 71 and the side indicator portion row 72 may be visually different from each other, and before the color change, the center indicator portion row 71 and the side indicator portion row 72 may be visually identical to each other. The term "visually different" in the present invention means that the object can be distinguished from each other when observed by a test subject, who is brightly illuminated indoors (illuminance: 500lx to 750lx (lux)) with daytime white (color temperature: 4600K to 5400K (kelvin)), and has good vision (1.0 or more) in both eyes at a distance of about 30cm to 50 cm.

In the mode in which the color of the center indicator portion row 71 and the color of the side indicator portion row 72 after the color change are different from each other, the color of the center indicator portion row 71 may be formed of a color that is a color opposite to the color of the side indicator portion row 72. With this configuration, the assist person can more easily recognize the difference between the center indicator row 71 and the side indicator row 72. Here, the opposite color of a certain color means a complementary color of a certain color (a color located on the opposite side in the hue circle) and a color adjacent to the complementary color or adjacent to one color through the other color in the hue circle based on the munsell color system in which the hue is divided into 20 parts. The pattern portions of the center indicator row and the pattern portions of the side indicator row may be visually different, may be partially the same, or may be visually different from each other.

The pattern part 80 of the center indicator column 71 may have a first pattern part 81 and a second pattern part 82. The first pattern part 81 and the second pattern part 82 may be visually different after being discolored. That is, the center indicator portion row 71 may have visually different pattern portions, or may have three or more pattern portions. The visually different pattern portions may be configured not only in different shapes, colors, and sizes of the patterns, but also in the same shape of the patterns and in different angles. Since the first pattern part 81 and the second pattern part 82 are visually different from each other, the pattern parts are easily distinguished from each other. The assistant can easily grasp the position of each pattern portion 80 in the center indicator row 71, and can grasp the urination amount and the urination position more appropriately with the pattern portions 80 as scales.

The first pattern part 81 and the second pattern part 82 may also be mutually unrelated. Since the pattern portions are mutually unrelated to each other, the pattern portions are not easily confused by the assistant. Therefore, the assistant can easily distinguish the pattern portions and recognize them as the scale. Therefore, the urination amount and the urination position can be grasped more appropriately using the pattern portion 80 as a scale.

Here, "irrelevant to interaction" means that, in the case where one pattern part is described as being relevant to or having performed an action or activity, and the other pattern part is not a subject of the action or activity and is not relevant to the action or activity, the interaction is irrelevant. In another example, when a pattern is classified into a plant, an animal, a person, food, and an abstract pattern (heart, diamond, and star), pattern portions having different classifications are not correlated with each other. For example, the flower pattern as the first pattern portion is interactively unrelated to the star pattern as the second pattern portion 82. In addition, within the abstract pattern classification, patterns without relevance are mutually irrelevant, and heart-shaped patterns and star-shaped patterns have no relevance and are mutually irrelevant.

The maximum length of the first pattern part 81 may be longer than the maximum length of the second pattern part 82. The maximum length may be the maximum length in the front-rear direction L or the maximum length in the width direction W. The first pattern portion 81 is more noticeable than the second pattern portion 82, and the first pattern portion 81 easily functions as a primary scale for identifying the urine discharge amount. Further, since the maximum length of the second pattern portion 82 is short, the second pattern portion 82 functions as a fine scale, and the urination can be grasped more finely. Preferably, the maximum length of the second pattern part may be 1/2 or less of the maximum length of the first pattern part. It is easy for the helper to distinguish between the primary scale and the secondary scale.

At least one second pattern portion 82 is disposed between the first pattern portions 81 in the front-rear direction L. The urination can be grasped not only from the first pattern part 81 but also from the second pattern part 82, and the urination can be grasped more finely.

More preferably, the first pattern part 81 and the second pattern part 82 may be alternately arranged in the front-rear direction L. Both the first pattern part 81 and the second pattern part 82 function as scales, and it is easy to grasp urination more finely. The distance between the first pattern part 81 and the second pattern part 82 in the front-rear direction L is preferably 5mm or less. Since the first pattern parts 81 and the second pattern parts 82 are alternately arranged, both the first pattern parts 81 and the second pattern parts 82 are easy to attract attention, and urination can be easily grasped from the pattern parts. Further, since the interval between the first pattern portion and the second pattern portion is 5mm or less, it is easy to compare the first pattern portion 81 and the second pattern portion 82, and it is easy to grasp not only whether each pattern portion is discolored or not but also the discolored range of the pattern portion, and it is easy to grasp urination more finely. In order to integrate the first pattern portion and the second pattern portion and easily function as a scale, the center of the first pattern portion and the center of the second pattern portion preferably coincide with each other in a direction (width direction) orthogonal to the direction (front-rear direction) in which the pattern portions are arranged.

The maximum length L80 in the front-rear direction L of the pattern portions 80 may be longer than the interval G80 in the front-rear direction L between the pattern portions 80. The maximum length L80 in the front-rear direction of the pattern portion 80 is relatively long, so that each pattern portion 80 is easily noticeable and easily functions as a scale. Further, since the length of the pattern portion 80 in the front-rear direction L is relatively long, it is possible to grasp not only whether each pattern portion 80 is discolored but also a discolored range of the pattern portion 80 (for example, a half area of one pattern portion is discolored), and it is easy to grasp urination more finely.

The pitch P80 in the front-rear direction L of the pattern portion 80 may be constant. With this structure, the pattern portion 80 easily functions as a scale for indicating the urine output. The pitch is a distance between centers of the pattern portions 80 in the adjacent direction. In the embodiment in which pattern portion 80 includes first pattern portion 81 and second pattern portion 82, pitch P81 of first pattern portion 81 may be constant, or pitch P82 of second pattern portion 82 may be constant. More preferably, the pitch P80 between the first pattern part 81 and the second pattern part 82 may be constant. Further, the pitch in the present invention must be a concept that also includes a case within a 5% error range with respect to the average value of the pitch.

A plurality of pattern portions 80 are preferably arranged in one direction, for example, in the front-rear direction L at a pitch of 10mm or more and less than 30 mm. The pitch is a distance between centers of the pattern portions in the adjacent directions. In the garment such as coveralls, when the buttons at the position facing the crotch region S3 are unfastened, a gap of about 30mm is generated in the front-rear direction L in the crotch region S3. If a plurality of pattern portions are arranged at a pitch of 10mm or more and less than 30mm, at least one entire pattern portion can be confirmed from a gap of about 30mm (gap of coveralls). This makes it possible to easily grasp whether or not urine adheres to the crotch region S3 of the absorbent article from the gap between the pants.

The pitch of the pattern part 80 may be 10mm or 5 mm. The dimensions 10mm and 5mm are dimensions that are frequently used in daily life, and the dimensions can be easily and intuitively grasped from the pattern portions arranged at the intervals. For example, the pitch of the first pattern part 81 may be 10mm, and the center of the second pattern part 82 may be located at the middle position of the first pattern part 81 (a position 5mm away from the center of the first pattern part). A scale of 5mm pitch can be expressed by the first pattern part 81 and the second pattern part 82.

The interval G80 between the pattern portions 80 may be constant. With this configuration, the pattern portion easily functions as a scale for marking the urine output. In the embodiment in which pattern portion 80 includes first pattern portion 81 and second pattern portion 82, interval G81 of first pattern portion 81 may be constant, or interval G82 of second pattern portion 82 may be constant. More preferably, the distance G80 between the first pattern part 81 and the second pattern part 82 may be constant. Further, the interval in the present invention must be a concept that also includes the case within a 5% error range with respect to the average value of the interval. As in the center indicator row of the present embodiment, the first pattern portion and the second pattern portion may partially overlap in the width direction, and the interval G80 between the pattern portions may not be formed.

Many users such as infants wear clothes such as jumpsuits that can open the crotch region. At this time, the assistant recognizes the indicator 70 provided in the crotch region of the absorbent article by opening the crotch region of the garment, and determines whether or not urine is deposited. Here, in the garment such as coveralls, a gap of about 30mm in the front-rear direction and about 30mm in the width direction can be generated in the crotch region S3. Therefore, it is preferable to arrange the indicator 70 so as to be visible within a range of 30mm including the center in the width direction of the absorbent article and a range of 30mm including the center in the front-rear direction of the absorbent article.

The interval between the adjacent pattern portions in the pattern portion is preferably shorter than the length of the pattern portion in the direction in which the pattern portions are arranged. Thus, the plurality of pattern portions are arranged in one direction at relatively short intervals, and therefore, the assistant can easily recognize the indication portion as the entire aggregate of the pattern portions. Further, since the pattern portions are arranged in one direction at relatively short intervals, it is easy to determine which region of the absorbent article 10 urine has reached.

The length of the pattern portion in the front-rear direction and the length of the pattern portion in the width direction are preferably 20mm or less. Many users such as infants wear clothes such as jumpsuits that can open the crotch region. At this time, the assistant such as the mother recognizes the pattern portion provided in the crotch region of the absorbent article by opening the crotch region of the garment, and determines whether or not urine is attached. Here, in the garment such as coveralls, a gap of about 30mm in the front-rear direction and about 30mm in the width direction can be generated in the crotch region. In this case, since the length of the pattern portion is 20mm or less, the area around the indication portion can be sufficiently recognized, and thus the assistant can easily recognize the pattern portion by the difference from the surrounding area.

The pattern portion may have a length of 4mm or more in the front-rear direction and the width direction. The pattern part is prevented from becoming too small, and the assist person can easily recognize the pattern part. In the embodiment including the first pattern portion 81 and the second pattern portion 82, the length of the first pattern portion in the front-rear direction and the length of the first pattern portion in the width direction may be 10mm or more.

More preferably, the length of the pattern part 80 is preferably 12.5mm or more in the direction in which the pattern parts 80 are arranged, for example, the front-rear direction L. Here, in the garment such as coveralls, as described above, a gap of about 30mm can be generated in the crotch region. Therefore, if the length of the pattern portion is 12.5mm or more, the size of the gap of about 30mm can be secured for the pattern portion 80. Thus, the assistant can easily recognize the pattern portion from the gap of about 30 mm.

In order to facilitate the recognition of the indicator 70 by the assistant, one, preferably two pattern portions are preferably visible from a gap of about 30 mm. Further, in order to prevent the pattern portion from becoming too small, it is more preferable that the number of the pattern portions to be visible through a gap of about 30mm be less than three. In consideration of such conditions, the length of the pattern portions in one direction may be in the range of 9 to 29mm, and the distance between the pattern portions may be in the range of 1 to 21 mm.

The indication portion array may be provided with a low visibility portion having a low visibility after color change and a high visibility portion having a higher visibility than the low visibility portion. The low visibility portion is configured by a non-application portion that is not applied with the color-changing agent over the entire length of the indicator row in the width direction, or is configured such that when the sum of the lengths of the overlapping portions of an imaginary straight line that transversely passes through an arbitrary portion of the indicator row and the application portion is defined as the application width of the color-changing agent at the portion, the low visibility portion is smaller than the high visibility portion. By providing the low visibility portion, the presence or absence of the discoloration of the color-changing agent application portion and the degree of expansion of the discoloration portion (the position of the excreted liquid) can be easily and accurately confirmed, as compared with a case where the color-changing agent application portion is continuous in the front-rear direction with the same width (the length in the width direction is constant).

The "visibility of the applied portion of the color-changing agent after color change" referred to herein means visibility (easy visibility) when the absorbent article is visually observed from the outside and the indicator row is observed through the outer sheet 24 and the back sheet 23. The high-visibility portion is located on both sides in the front-rear direction with the low-visibility portion therebetween. In the present embodiment, the low visibility portion may be formed of a non-coated portion to which a colorant is not applied over the entire length in the width direction of each of the

indicator rows

71, 72. The non-coating portion is a portion between the first pattern portion and the second pattern portion in the embodiment having no coupling portion. In addition, in a mode in which the length of the second pattern portion in the width direction is shorter than the length of the first pattern portion in the width direction, the portion where the second pattern portion is arranged also constitutes the low visibility portion. In addition, in a mode in which the length of the coupling portion in the width direction is shorter than the length of the pattern portion in the width direction, the portion where the coupling portion is disposed also constitutes the low visibility portion.

The absorption concave portions 41 may be disposed on both sides of the center indicator row 71 in the width direction. The body fluid excreted from the excretory opening spreads from the opposing portion in the front-rear direction L and the width direction W in a circle center shape. Therefore, even if the center indicator row 71 is disposed to face the excretion portion, if the body fluid is excessively diffused in the width direction, the body fluid is not diffused in the front-rear direction L in which the center indicator row 71 extends, and the center indicator row 71 is not discolored, so that the urination state cannot be accurately grasped. Since the absorbent recessed portions 41 are disposed on both sides of the center indicating portion row 71 in the width direction, when the body fluid is discharged to a position facing the center indicating portion row 71, the body fluid can be prevented from spreading outward in the width direction by the absorbent recessed portions 41 on both sides, the body fluid can be spread along the center indicating portion row 71, and the urination state can be grasped more accurately by the center indicating portion row 71.

As shown in fig. 3, in a region overlapping with the slit as the absorbent concave 41 in a plan view, the sheets arranged across the absorbent core 31 in the thickness direction T may be joined to each other. The sheet includes a top sheet, a side sheet, a core cladding, a back sheet, and an exterior sheet. In the absorbent article of the present embodiment, the core wrap layers 32 disposed so as to sandwich the absorbent core 31 in the thickness direction are joined to each other. By both the slit and the portion where the sheet is joined to each other, the body fluid can be suppressed from spreading to the outside in the width direction than the slit, the body fluid can be spread along the center indicating section row 71, and the excretion can be grasped more accurately by the center indicating section row 71.

The side surface indication part row 72 as the auxiliary indication part may be disposed on the outer side in the width direction than the absorption concave part 41. The side surface indication part row 72 can indicate that the body fluid has spread outward in the width direction over the absorption concave part 41. Therefore, when the urination amount is large or the wearing position is shifted, the assisting person can appropriately grasp the urination state from the side indicating section row 72, and can suppress side leakage.

Next, the indication unit according to the modification will be described with reference to fig. 4 and 5. Fig. 4 and 5 are plan views of the absorbent article viewed from the non-skin surface side, and show the indicator row according to the modified example. In the following description of the modified examples, the same reference numerals are used for the same components as those of the above-described embodiment, and the description thereof is omitted. The indicator row according to modifications 1 to 5 is composed of an aggregate of a plurality of pattern portions, as in the above-described embodiment.

Fig. 4(a) shows an indicator column 701 according to modification 1. The indicator row 701 includes a first pattern portion 81 and a second pattern portion 82, the length of the first pattern portion 81 in the front-rear direction L is the same as the length of the second pattern portion 82 in the front-rear direction L, and the length of the first pattern portion 81 in the width direction W is the same as the length of the second pattern portion 82 in the width direction W.

The pattern portions 80 may be connected to each other via a connection portion 85 constituting the indicator row. The coupling portion 85 facilitates the identification of the indicator array 701 formed by the pattern portion 80 as an integrated array, and the assistant can easily grasp the urination position with respect to the entire indicator array 701. The coupling portion 85 of the present embodiment is formed of a linear line connecting the first pattern portion 81 and the second pattern portion 82.

Further, the coupling portion 85 and the plurality of pattern portions 80 may be configured to simulate a predetermined shape. By simulating a predetermined shape in daily use, the pattern portion easily functions as a scale, and the assistant can easily grasp urination with feeling. In another modification, the second pattern portions 82 may be arranged to connect the first pattern portions 81 to each other, and the second pattern portions 82 may constitute connection portions.

Fig. 4(b) shows an instruction section column 702 according to modification 2. The pattern portion according to modification 2 is surrounded by the surrounding portion 86 constituting the indicating portion row 702. The surrounding portion 86 surrounds the pattern portion, whereby each pattern portion 80 can be made noticeable. The assistant can easily grasp the position of each pattern portion 80 in the indicating portion row 702, and can grasp the urination amount and the urination position more appropriately with the pattern portion 80 as a scale.

In addition, since the surrounding portion 86 is discolored by urine together with the pattern portion 80, the assist person can easily recognize the pattern portion 80 as a characteristic shape. In the example shown in fig. 4(b), the surrounding portion 86 has a quadrangular shape surrounding the pattern portion 80. As shown in fig. 4(b), the surrounding portion 86 may be formed in one layer, or may be formed in two or more layers. When the surrounding portion 86 is formed in two layers, the pattern portion 80 is more noticeable.

In addition, the first pattern part 81 and the second pattern part 82 are cross-related. The first pattern portion 81 is a double-layer circular pattern, and the second pattern portion 82 is a single-layer circular pattern. Since the first pattern part 81 and the second pattern part 82 are cross-related, it is easy for the assistant to recognize both the first pattern part 81 and the second pattern part 82 as the pattern part 80 representing the scale. Therefore, the urination amount and the urination position can be grasped more appropriately by using the whole of the first pattern part 81 and the second pattern part 82 as a scale.

Here, "interactive correlation" means interactive correlation when both pattern portions are described as relating to an action or an activity or when an action or an activity is performed, and when both pattern portions are not objects of an action or an activity and are not relating to an action or an activity. In another example, when a pattern is classified into a plant, an animal, a person, food, and an abstract pattern (heart, diamond, star), pattern parts in the same classification are correlated with each other.

Fig. 4(c) shows an indicator column 703 according to modification 3. The indicator row according to modification 3 includes surrounding portions 86 surrounding the pattern portion, and the surrounding portions 86 are connected to each other. The surrounding portion 86 has a shape that borders the outer shape of the pattern portion 80. By having the surrounding portion 86 and having a shape in which the outer shape of the pattern portion 80 is framed, the pattern portion 80 becomes a more characteristic shape, and the pattern portion 80 is more noticeable.

Fig. 5(a) and 5(b) show an instruction section column 704 according to modification 4 and an instruction section column 705 according to modification 5. In the indicating section row 704 and the indicating section row 705, the pattern sections arranged side by side in the front-rear direction indicate the urination state in stages. By representing urination by stages by the pattern portion, the pattern portion more easily functions as a scale. The pattern portion may be arranged to gradually rise from the center in the front-rear direction toward the outer side in the front-rear direction in a stepwise manner. According to such a pattern portion, it is easier to appropriately grasp the urine output in a first stage of urine output only at a position close to the excretory opening, a second stage in which the urine output is increased compared to the first stage, and the like.

In the example shown in fig. 5(a), the stages are shown by pattern portions containing numbers. By easily and simply representing urination by numbers in stages, the pattern portion more easily functions as a scale. In the example shown in fig. 5(b), the steps are represented by pattern portions including patterns that change stepwise. Specifically, the first stage is represented by an egg-shaped pattern, the second stage is represented by a pattern in which an egg has cracks, the third stage is represented by a pattern in which an egg has cracks, and the fourth stage is represented by a pattern of a chick. In addition, as a pattern indicating another stage, a face pattern whose expression changes stepwise may be mentioned. The first stage can be represented by a smiley face pattern, the stage being represented by an expression that gradually becomes sad.

Next, the absorbent article container will be described with reference to fig. 6. Fig. 6(a) shows a package 100A of an absorbent article according to the first embodiment, and fig. 6(B) shows a package 100B of an absorbent article according to the second embodiment. The

container

100A, 100B includes a plurality of absorbent articles and a packaging bag 101 for storing the plurality of absorbent articles. A removal port, not shown, is formed in the packaging bag 101, and the absorbent article inside is removed through the removal port.

The plurality of absorbent articles 10 have: a first absorbent article 10A having a first decorative portion 27; and a second absorbent article 10B having a second decorative portion 28 that is visually distinct from the first decorative portion 27. Since the first decorative portion 27 and the second decorative portion 28 are different, a plurality of types of absorbent articles can be accommodated in one packaging bag 101, and the decorativeness can be improved. The first absorbent article 10A and the second absorbent article 10B may be different only in the form of the decorative portion, and the other structures (the size of the absorbent article, the shape of the absorbent core, and the like) may be the same.

The first decorative portion 27 and the second decorative portion 28 can be recognized from the non-skin surface side T2 of the absorbent article, and are printed on the exterior sheet 24 or the back sheet 23, for example. The assistant can recognize the first decorative portion 27, the second decorative portion 28, and the pattern portion 80 when the assistant views the absorbent article from the non-skin surface side. The different decorativeness of the decorative part and the index of urination based on the indicator pattern part 80 can be simultaneously exerted. Further, the first decorative portion 27 and the second decorative portion 28 may be provided on the surface on which the indicator is disposed in a state where the absorbent article is taken out from the packaging bag. This allows the assistant to recognize the indicator and the decorative part together before using the absorbent article.

In the structure in which the decorative portions (the first decorative portion 27 and the second decorative portion 28) are visible from the non-skin surface side T2 of the absorbent article, the decorative portions may show a display relating to the pattern portion. For example, the presence of the pattern portion can be made noticeable by the decorative portion, or the function as a scale can be assisted by a numeral or the like. Preferably, the decorative portion and the pattern portion do not overlap each other in a plan view. The decorative part and the pattern part are not easy to be confused, and the pattern part of the indication part can be attracted.

Further, the distance between the center position of the pattern portion of the indicator row in the first absorbent article 10A and the center position of the pattern portion of the indicator row in the second absorbent article 10B may be equal to or less than a predetermined length. The distance of the center position of the pattern portion is obtained by comparing the center position of the pattern portion in the entire first absorbent article 10A with the center position of the pattern portion in the entire second absorbent article 10B. For example, when the center position of the pattern portion of the first absorbent article 10A is shifted to the left side by 10mm and to the front side by 10mm from the reference, and the center position of the pattern portion of the second absorbent article 10B is shifted to the left side by 5mm and to the front side by 20mm from the reference, with the center in the width direction of the absorbent article and the center in the front-rear direction as the reference, the distance between the center positions in the width direction is 5mm, and the distance between the center positions in the front-rear direction is 10 mm.

In the front-rear direction, the distance between the center position of the pattern portion of the first absorbent article 10A and the center position of the pattern portion of the second absorbent article 10B is 10% or less with respect to the length of the pattern portion. In addition, the distance between the center position of the pattern portion of the first absorbent article 10A and the center position of the pattern portion of the second absorbent article 10B in the width direction is 10% or less with respect to the length of the pattern portion. In the first absorbent article 10A and the second absorbent article 10B, the center positions of the pattern portions are substantially the same, and therefore, it is possible to show the urination condition in the same manner in any absorbent article while achieving different decorativeness. The assistant can similarly grasp urination even when using absorbent articles having different designs.

As shown in fig. 6(a), the pattern portion of the first absorbent article 10A and the pattern portion of the second absorbent article 10B may be visually the same. The visually identical pattern portions are visually indistinguishable pattern portions, and are patterns of identical size and shape. Since the pattern portions are visually the same, even if absorbent articles having different designs of the decorative portions are used, urination can be grasped in the same manner.

As shown in fig. 6(B), the pattern portion of the first absorbent article 10A and the pattern portion of the second absorbent article 10B may be visually different. Together with the first decorative portion and the second decorative portion, different decorative properties can be imparted to the first absorbent article 10A and the second absorbent article 10B by the pattern portions. Even if the pattern portions are visually different, the center positions of the pattern portions are the same, and therefore, the pattern portions can function as a scale.

In the configuration in which the pattern portion of the first absorbent article 10A and the pattern portion of the second absorbent article 10B are visually different from each other, the pattern portions may be mutually related or may have the same sense of world. The same character pattern and the same story-based pattern of the same series can be exemplified by the same world-feeling pattern section.

While the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that the present invention is not limited to the embodiments described in the present specification. The present invention can be implemented as modifications and alterations without departing from the spirit and scope of the present invention defined by the description of the claims. The description is thus to be regarded as illustrative instead of limiting, and the invention is not intended to be limited thereto.

Further, the entire contents of japanese patent application No. 2018-201332 filed on 25/10/2018 are incorporated by reference into the present specification.
