Description

[Technical field]

[0001] The present disclosure relates to absorbent articles, methods for manufacturing absorbent articles, packages, and groups of packages. [Background technology]

[0002] Patent Document 1 describes a tape-type diaper that includes a water-permeable top sheet, a water-impermeable back sheet, and an absorbent disposed between the top sheet and the back sheet. The diaper has an indicator that changes color when it comes into contact with moisture to display messages such as "Thank you" and "I love you." [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 6949805 Summary of the Invention [Problem to be solved by the invention]

[0004] Users of absorbent articles (e.g., parents or caregivers) often bear physical or psychological burdens due to daily childcare or caregiving. The above-mentioned diaper displays a message that evokes positive emotions when the wearer (e.g., a child or a person being cared for) urinates, thereby improving the user's sense of self-affirmation and reducing the user's stress. However, with the above-mentioned diaper, the message is displayed only when the wearer urinates. Also, depending on the urination position, the indicator may not get wet and the message may not be displayed.

[0005] Therefore, an object of the present disclosure is to provide an absorbent article, a manufacturing method for an absorbent article, a package, and a group of packages that can effectively reduce stress in a user. [Means for solving the problem]

[0006] The absorbent article according to one embodiment is a pants-type absorbent article including an absorbent body having an absorbent substance, a ventral waist portion connected to one end of the absorbent body in the longitudinal direction, and a rear waist portion connected to the other end of the absorbent body in the longitudinal direction. The absorbent article has decorative elements that evoke positive feelings in a user, and the decorative elements are drawn with a colorant that does not discolor when in contact with moisture.

[0007] In the absorbent article according to the present embodiment, the decorative elements that induce positive feelings in the user are drawn with a coloring agent that does not discolor when in contact with moisture, so that the decorative elements can be displayed regardless of whether the user has urinated or not, thereby improving the user's sense of self-affirmation and effectively reducing the user's stress.

[0008] The absorbent body may have an indicator that changes color upon contact with moisture, and the decorative element may be disposed in a position that does not overlap the indicator. By disposing the decorative element in a position that does not overlap the indicator, it is possible to prevent the visibility of the decorative element from being reduced due to the discoloration of the indicator during urination.

[0009] The absorbent body includes a nonwoven exterior sheet disposed on the nonskin-facing side of the absorbent body, and the line width of the decorative element may be greater than the thickness of the fibers of the nonwoven fabric constituting the exterior sheet. By increasing the line width of the decorative element, the visibility of the decorative element can be improved.

[0010] The absorbent article has a second decorative element arranged at a position different from the first decorative element, and the second decorative element may include a display that evokes positive emotions in the user and may be drawn with a colorant that does not discolor when in contact with moisture. By drawing the first decorative element and the second decorative element on the absorbent article, the user has more opportunities to come into contact with the display that evokes positive emotions. As a result, the user's sense of self-affirmation can be further improved.

[0011] The absorbent article may further comprise a stretchable elastic member, and the decorative element may be disposed in a position not overlapping the elastic member. In the region where the elastic member is disposed, wrinkles are generated due to contraction of the elastic member. By disposing the decorative element in a position not overlapping the elastic member, it is possible to prevent a decrease in visibility of the decorative element due to wrinkles.

[0012] The ventral waist portion and the rear waist portion may have waist stretchable members that are stretchable in the waist direction of the wearer, and the decorative elements may be arranged in a position that does not overlap the waist stretchable members. By arranging the decorative elements in a position that does not overlap the waist stretchable members, it is possible to prevent a decrease in visibility of the decorative elements due to wrinkles caused by contraction of the waist stretchable members.

[0013] The absorbent article may further include a post-treatment tape for holding the absorbent article in a rolled state when discarded, and the decorative element may be drawn on the post-treatment tape. For users who are raising or caring for their elderly relatives, changing diapers is one of the tasks that places a particularly large physical or psychological burden on them. By drawing the decorative element on the post-treatment tape, the user can see the decorative element when changing the diaper, and thus has more opportunities to touch the decorative element. As a result, the user's stress can be effectively reduced.

[0014] The entire decorative element may be disposed on the post-treatment tape, in which case the visibility of the decorative element is improved.

[0015] In one aspect, the decorative element may include a character string that evokes a positive emotion in a user, and the entire character string may be disposed on the post-processing tape. By disposing the entire character string on the post-processing tape, the user can easily recognize the character string.

[0016] The longitudinal end of the post-treatment tape may be colored, and the decorative element may be painted with a coloring agent of the same color as the end of the post-treatment tape. By making the color of the decorative element and the color of the end of the post-treatment tape the same, a sense of uniformity in appearance can be achieved, and the design of the absorbent article can be improved.

[0017] The longitudinal end of the post-treatment tape may be colored, and the decorative element may be drawn with a coloring agent of a different color from the color of the end of the post-treatment tape. By drawing the decorative element with a color different from the color of the end of the post-treatment tape, the decorative element becomes more noticeable due to the color contrast. As a result, the visibility of the decorative element can be improved.

[0018] The absorbent article may further include a pair of post-processing tapes for holding the absorbent article in a rolled state when the absorbent article is disposed of, and the first decorative element may be disposed on one of the pair of post-processing tapes, and the second decorative element may be disposed on the other of the pair of post-processing tapes. By depicting the first decorative element and the second decorative element on the pair of post-processing tapes, the user has more opportunities to come into contact with displays that evoke positive emotions. As a result, the user's stress can be effectively reduced.

[0019] The decorative elements include two or more elements selected from among character strings, graphics, and character illustrations, and the two or more elements may be drawn on the post-treatment tape so as to be adjacent to each other or overlap each other. By displaying decorative elements that include at least two or more elements selected from among character strings, graphics, and character illustrations, the decorative elements can be made more noticeable and are more likely to induce positive emotions in the user. As a result, the user's stress can be effectively reduced.

[0020] The post-treatment tape includes a lower layer fixed to the back waistband portion, an upper layer having an adhesive surface to be adhered to the outer surface of the absorbent article in a rolled-up state, and an intermediate layer connecting the lower layer and the upper layer, the upper layer and the intermediate layer being arranged so as to overlap the lower layer in the thickness direction, the lower layer or the intermediate layer may have a decorative element drawn thereon, and the upper layer may have a masking function to reduce the visibility of the decorative element. When the upper layer has a masking function, the decorative element drawn on the lower layer or the intermediate layer is displayed when the upper layer is peeled off to keep the absorbent article in a rolled-up state. The display of an unexpected decorative element increases the joy of the user and is likely to cause positive emotions in the user.

[0021] The upper layer may depict a concealing element that reduces the visibility of the decorative element, and the color difference between the back waist portion and the concealing element may be smaller than the color difference between the back waist portion and the decorative element. By reducing the color difference between the back waist portion and the concealing element, the visibility of the decorative element can be reduced.

[0022] In one embodiment, a method for manufacturing a pants-type absorbent article is provided, the pants-type absorbent article includes an absorbent body having an absorbent body, a ventral waist part connected to one longitudinal end of the absorbent body, a rear waist part connected to the other longitudinal end of the absorbent body, and a post-treatment tape fixed to the rear waist part. The method for manufacturing the absorbent article includes a step of dividing a decorative film including a first decorative element that induces positive feelings in a user to form a post-treatment tape having the first decorative element, and a step of fixing the post-treatment tape having the first decorative element to the rear waist part of the first absorbent article.

[0023] The manufacturing method according to the above aspect manufactures a pants-type absorbent article having a post-treatment tape with a first decorative element that induces positive feelings in the user. By displaying the first decorative element, this absorbent article can improve the user's self-esteem and effectively reduce the user's stress.

[0024] The decorative film may further include a second decorative element that induces a positive emotion in a user different from the first decorative element, and the manufacturing method of the absorbent article may further include a step of dividing the decorative film to form a post-treatment tape having the second decorative element, and a step of fixing the post-treatment tape having the second decorative element to the rear waist portion of the second absorbent article. According to this absorbent article, a first absorbent article having the first decorative element and a second absorbent article having the second decorative element can be manufactured.

[0025] In one embodiment, a package is provided that contains a plurality of absorbent articles. Each of the plurality of absorbent articles is a pants-type absorbent article including an absorbent body having an absorbent body, a ventral waistline portion connected to one end of the absorbent body in the longitudinal direction, and a rear waistline portion connected to the other end of the absorbent body in the longitudinal direction. The plurality of absorbent articles includes a first absorbent article having a first decorative element that induces a positive emotion in a user, and a second absorbent article having a second decorative element that induces a positive emotion in a user, the first decorative element and the second decorative element including different character strings or figures, and drawn with a colorant that does not discolor when in contact with moisture.

[0026] In this embodiment, the first and second decorative elements that do not discolor when in contact with water are drawn on the first and second absorbent articles, so that the first and second decorative elements can be displayed regardless of whether the user has urinated or not, thereby improving the user's self-esteem and effectively reducing the user's stress.

[0027] The first decorative element or the second decorative element may be depicted on the outer surface of the package. In this case, the user can recognize that the package contains an absorbent article having the first decorative element or the second decorative element without opening the package.

[0028] A package group according to one embodiment includes a first package containing a first absorbent article having a first shape or size, and a second package containing a second absorbent article having a second shape or size, and the first package and the second package have the same brand name displayed thereon, and the first absorbent article and the second absorbent article have decorative elements drawn in different positions that induce positive emotions in the user. This package group does not become monotonous because the decorative elements are arranged in different positions even for the same brand, and the positive emotions derived from the decorative elements are easily continued. In addition, when the sizes of the first absorbent article and the second absorbent article are different, the positive emotions can be derived from the decorative elements if the absorbent articles are of the same brand and include decorative elements, even if the size is changed. Effect of the Invention

[0029] According to various aspects of the present invention, it is possible to effectively reduce stress on a user. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0031] Hereinafter, an embodiment of the present disclosure will be described in detail with reference to the drawings. In the description of the drawings, the same elements are given the same reference numerals, and duplicated descriptions are omitted. The drawings may be partially simplified or exaggerated for ease of understanding, and the dimensional ratios are not limited to those shown in the drawings.

[0032] The absorbent article 1 according to one embodiment will be described below. Fig. 1 is a perspective view of the absorbent article 1 according to one embodiment. Fig. 2 is a plan view of the absorbent article 1 as viewed from the skin-facing side Z1, and Fig. 3 is a plan view of the absorbent article 1 as viewed from the non-skin-facing side Z2. Fig. 4 is a cross-sectional view of the absorbent article 1. The absorbent article 1 shown in Figs. 1 to 4 is a pants-type disposable diaper that absorbs urine from a wearer.

[0033] 2 and 3 show the absorbent article 1 in an unfolded state in which the absorbent article 1 is cut at a side end 34 of the ventral waistline portion 3 and a side end 44 of the back waistline portion 4, which will be described later, and is stretched to a state in which no wrinkles are formed. The skin-facing side Z1 is the side that faces the skin of the wearer when the absorbent article 1 is worn, and the non-skin-facing side Z2 is the side that faces the opposite side to the skin of the wearer when the absorbent article 1 is worn. In the following description, a person who wears the absorbent article 1 is referred to as a "wearer", and a person who makes the wearer wear the absorbent article 1 is referred to as a "user". Typically, the wearer is a child or a person being cared for, and the user is a parent or a caregiver. In the following description, the positional relationship in the unfolded state is described unless otherwise specified.

[0034] As shown in Figures 2 and 3, the absorbent article 1 extends in a lateral direction X and a longitudinal direction Y when in an unfolded state. The longitudinal direction Y is a longitudinal direction extending between the abdominal side and the dorsal side of a wearer when the absorbent article 1 is worn. The lateral direction X is a direction perpendicular to the longitudinal direction Y, and is a width direction extending in the left-right direction of the wearer when the absorbent article 1 is worn. The thickness direction Z is a direction perpendicular to the lateral direction X and the longitudinal direction Y. In the following description, one end side of the absorbent article 1 in the longitudinal direction Y may be referred to as the abdominal side, and the other end side in the longitudinal direction Y may be referred to as the dorsal side.

[0035] The absorbent article 1 includes a ventral waist portion 3, a rear waist portion 4, and an absorbent main body 10. The absorbent main body 10 has a generally rectangular planar shape that is elongated in the longitudinal direction Y of the absorbent article 1. As shown in Fig. 2 and Fig. 3, the absorbent main body 10 includes a ventral region 10a disposed on one end side of the longitudinal direction Y, a rear region 10b disposed on the other end side of the longitudinal direction Y, and a crotch region 10c disposed between the ventral region 10a and the rear region 10b in the longitudinal direction Y.

[0036] The ventral waist portion 3 is joined to the ventral region 10a of the absorbent body 10 from the non-skin-facing side Z2. The back waist portion 4 is joined to the back region 10b of the absorbent body 10 from the non-skin-facing side Z2. The absorbent body 10 is folded in half so that the ventral waist portion 3 and the back waist portion 4 face each other, and the lateral end 34 of the ventral waist portion 3 in the lateral direction X and the lateral end 44 of the back waist portion 4 in the lateral direction X are joined to connect the ventral waist portion 3 and the back waist portion 4 in a belt-like manner. As a result, as shown in FIG. 1, the absorbent article 1 is formed into a pants-type. In the following description, the state in which the ventral waist portion 3 and the back waist portion 4 are connected in a belt-like manner as described above is referred to as a "connected state". The absorbent article 1 in the connected state has a waist opening BH through which the wearer's waist passes and a pair of leg openings LH through which the wearer's legs pass.

[0037] The abdominal waist portion 3 has a substantially rectangular planar shape with the longitudinal direction being the lateral direction X of the absorbent article 1, and is disposed on the non-skin-facing side Z2 of the abdominal region 10a of the absorbent main body 10. The abdominal waist portion 3 includes a skin-facing sheet 31 disposed on the skin-facing side Z1, a non-skin-facing sheet 32 ​​disposed on the non-skin-facing side Z2, and a plurality of abdominal stretch members 33. Typically, the skin-facing sheet 31 and the non-skin-facing sheet 32 ​​are made of a plain white nonwoven fabric. For example, the skin-facing sheet 31 and the non-skin-facing sheet 32 ​​are made of an SMS nonwoven fabric in which spunbond, meltblown, and spunbond are laminated in this order, a spunbond nonwoven fabric, an air-through nonwoven fabric, or a laminate of these nonwoven fabrics. The skin-facing sheet 31 and the non-skin-facing sheet 32 ​​are joined to each other by an adhesive such as a hot melt.

[0038] The abdominal elastic members 33 are arranged at intervals in the vertical direction Y between the skin-facing sheet 31 and the non-skin-facing sheet 32. The abdominal elastic members 33 extend between the side ends 34 of the abdominal waist portion 3 in the horizontal direction X. Therefore, the abdominal waist portion 3 stretches in the horizontal direction X while fitting to the waist of the wearer. The abdominal elastic members 33 are made of an elastic material such as rubber or spandex. As shown in FIG. 3, the abdominal waist portion 3 has a cut region 35 formed at a position overlapping the absorbent body 14 where the abdominal elastic members 33 are not arranged. In the cut region 35, a part of the abdominal elastic members 33 is cut in the middle of the horizontal direction X. By forming the cut region 35, the contraction force of the abdominal elastic members 33 prevents the absorbent body 14 from contracting in the horizontal direction X.

[0039] The back waist portion 4 has a generally rectangular planar shape that is long in the lateral direction X of the absorbent article 1, and is disposed on the non-skin-facing side Z2 of the back region 10b of the absorbent body 10. The back waist portion 4 includes a skin-facing sheet 41 disposed on the skin-facing side Z1, a non-skin-facing sheet 42 disposed on the non-skin-facing side Z2, and a plurality of back stretch members 43. Typically, the skin-facing sheet 41 and the non-skin-facing sheet 42 are made of a plain white nonwoven fabric. For example, the skin-facing sheet 41 and the non-skin-facing sheet 42 are made of an SMS nonwoven fabric in which spunbond, meltblown, and spunbond are laminated in this order, a spunbond nonwoven fabric, an air-through nonwoven fabric, or a laminate of these nonwoven fabrics. The skin-facing sheet 41 and the non-skin-facing sheet 42 are joined to each other by an adhesive such as a hot melt.

[0040] The multiple back stretchable members 43 are arranged at intervals in the vertical direction Y between the skin-facing sheet 41 and the non-skin-facing sheet 42. The multiple back stretchable members 43 extend between the side ends 44 in the horizontal direction X of the back waist portion 4. Therefore, the back waist portion 4 stretches in the horizontal direction X while fitting to the waist of the wearer. The multiple back stretchable members 43 are made of an elastic material such as rubber or spandex. As shown in FIG. 3, the back waist portion 4 may have a cut region 35 formed in a position overlapping the absorbent body 14 where the multiple back stretchable members 43 are not arranged. That is, in the cut region 35, a part of the multiple back stretchable members 43 is cut in the middle of the horizontal direction X. By forming the cut region 35, the absorbent body 14 is prevented from contracting in the horizontal direction X due to the contraction force of the multiple back stretchable members 43. The abdominal stretchable member 33 and the back stretchable member 43 constitute a waist stretchable member that can stretch in the waist direction of the wearer.

[0041] The absorbent body 10 includes a top sheet 11, a back sheet 12, an exterior sheet 13, and an absorbent body 14. The top sheet 11 constitutes the surface of the absorbent body 10 that is in contact with the wearer, and is disposed on the skin-facing side Z1. The top sheet 11 is made of a water-permeable nonwoven fabric such as a spunbond nonwoven fabric, and covers the absorbent body 14 from the skin-facing side Z1. Typically, the top sheet 11 is white and plain. As shown in Fig. 4, the top sheet 11 is adhered to the surface of the skin-facing side Z1 of the absorbent body 14 by, for example, a hot melt adhesive HM.

[0042] The back sheet 12 is disposed closer to the non-skin side Z2 than the top sheet 11. The back sheet 12 is made of a water-impermeable film and covers the absorbent body 14 from the non-skin side Z2. The back sheet 12 is adhered to the surface of the non-skin side Z2 of the absorbent body 14 by, for example, a hot melt adhesive HM.

[0043] The exterior sheet 13 is disposed on the non-skin facing side Z2 of the back sheet 12 and constitutes the outermost layer of the absorbent body 10. The exterior sheet 13 is made of, for example, a water-impermeable nonwoven fabric. Typically, the exterior sheet 13 is plain white. The width of the exterior sheet 13 in the lateral direction X is greater than the width of the back sheet 12, and the exterior sheet 13 extends beyond the back sheet 12 on both sides in the lateral direction X.

[0044] The absorbent 14 is disposed between the top sheet 11 and the back sheet 12 of the absorbent body 10, and absorbs the wearer's urine that has permeated through the top sheet 11. As shown in FIG. 4, the absorbent 14 includes an absorbent core 15 and a core wrap 16. The absorbent core 15 includes, for example, pulp fiber and a superabsorbent polymer (SAP), and absorbs the wearer's urine. As the pulp of the absorbent core 15, for example, chemical pulp, cellulose fiber, rayon, acetate, or other cellulose fiber is used. As the superabsorbent polymer, for example, starch-based, acrylic acid-based, or amino acid-based particulate or fibrous polymer is used. The core wrap 16 is formed of, for example, tissue or a nonwoven sheet, and covers the skin-facing side Z1 and non-skin-facing side Z2 of the absorbent core 15. The core wrap 16 is bonded to the skin-facing side Z1 and non-skin-facing side Z2 of the absorbent core 15 by, for example, a hot melt adhesive HM.

[0045] As shown in Fig. 2, the absorbent main body 10 has a pair of leakage prevention gathers 80. The leakage prevention gathers 80 are disposed outside the absorbent core 15 in the lateral direction X, and prevent urine excreted into the absorbent core 15 from leaking in the lateral direction X. As shown in Fig. 4, the leakage prevention gathers 80 are formed by folding both left and right side portions of the exterior sheet 13 inward. The pair of leakage prevention gathers 80 are upright three-dimensional gathers, and are provided in the absorbent main body 10 along the longitudinal direction Y.

[0046] The leak-proof gathers 80 include a pair of elastic members 71 extending in the vertical direction Y, an upright portion 81 that stands up due to contraction of the pair of elastic members 71, a horizontal fixed portion 82 that serves as a fulcrum for the upright portion 81 in the horizontal direction X, and a vertical fixed portion 83 that serves as a fulcrum for the upright portion 81 in the vertical direction Y.

[0047] The pair of elastic members 71 are disposed between the inwardly folded exterior sheet 13 and extend in the longitudinal direction Y. The pair of elastic members 71 are, for example, rubber thread or flat rubber that is shrinkable in the longitudinal direction. The pair of elastic members 71 are disposed apart from each other across the longitudinal center line CW that divides the absorbent main body 10 into two in the transverse direction X, and are fixed to the exterior sheet 13 in a stretched state in the longitudinal direction Y. The ventral side ends of the pair of elastic members 71 are disposed in the ventral region 10a, and the dorsal side ends of the pair of elastic members 71 are disposed in the dorsal region 10b.

[0048] The lateral fixing parts 82 are formed on substantially the entire area of ​​the absorbent body 10 in the vertical direction Y at positions outside the standing parts 81 in the horizontal direction X. The lateral fixing parts 82 are part of the exterior sheet 13, and are joined to the top sheet 11 or the back sheet 12. For example, a hot melt adhesive HM is used to join the lateral fixing parts 82 (see FIG. 4). The lateral fixing parts 82 serve as standing fulcrums for the standing parts 81 in the horizontal direction X.

[0049] The vertical fixing portion 83 is formed at a position inside the horizontal fixing portion 82 in the horizontal direction X. The vertical fixing portion 83 is a part of the exterior sheet 13 and is joined to the top sheet 11 or the back sheet 12. For example, a hot melt adhesive is used for joining the vertical fixing portion 83. The vertical fixing portion 83 includes a ventral fixing portion 84 arranged in the ventral region 10a and a dorsal fixing portion 85 arranged in the dorsal region 10b. The ventral fixing portion 84 is formed between the ventral end portion 10F of the absorbent main body 10 and the ventral edge 15F of the absorbent core 15 in the vertical direction Y. The dorsal fixing portion 85 is formed between the dorsal end portion 10R of the absorbent main body 10 and the dorsal edge 15R of the absorbent core 15 in the vertical direction Y. The vertical fixing portion 83 serves as a standing fulcrum for the standing portion 81 in the vertical direction Y.

[0050] The standing portion 81 is formed between the ventral fixing portion 84 and the dorsal fixing portion 85. That is, the standing portion 81 is disposed inside the horizontal fixing portion 82 in the horizontal direction X and inside the vertical fixing portion 83 in the vertical direction Y. The standing portion 81 is a part of the exterior sheet 13 that is not fixed to the top sheet 11 or the back sheet 12. The standing portion 81 is connected to an elastic member 71 stretched in the vertical direction Y. When the elastic member 71 contracts in the vertical direction Y, the standing portion 81 stands up from the horizontal fixing portion 82 as a starting point. In this way, the standing portion 81 stands up at a position where it sandwiches the absorbent core 15 from the horizontal direction X, thereby preventing urine leakage.

[0051] As shown in FIG. 2, the absorbent article 1 further includes a pair of leg elastic members 40 that are stretchable in the length direction. The pair of leg elastic members 40 are disposed outside the pair of elastic members 71 in the lateral direction X. The ventral ends of the pair of leg elastic members 40 are disposed in the ventral region 10a, and the dorsal ends of the pair of leg elastic members 40 are disposed in the dorsal region 10b. The pair of leg elastic members 40 are made of an elastic material, such as rubber or spandex, that is stretchable in the length direction, and are connected to the exterior sheet 13 of the absorbent main body 10 along the side edges 10S of the absorbent main body 10 in a state stretched in the longitudinal direction Y. When the absorbent article 1 is worn, the pair of leg elastic members 40 contract in the longitudinal direction Y, so that the side edges 10S of the absorbent main body 10 fit around the legs of the wearer.

[0052] 3, the absorbent article 1 may have an indicator 72 that changes color when it comes into contact with moisture. The indicator 72 is disposed at a position overlapping the absorbent body 14 when viewed from the thickness direction Z, and is provided on the exterior sheet 13 so as to be visible from the non-skin-facing side Z2 of the absorbent main body 10. The indicator 72 changes color in reaction to bodily fluids absorbed by the absorbent body 14. The color change of the indicator 72 allows the user to know the degree of wetness of the absorbent body 14.

[0053] FIG. 5 is a rear view of the absorbent article 1. As shown in FIG. 5, the absorbent article 1 includes a post-treatment tape 50 for holding the absorbent article 1 in a rolled state when the absorbent article 1 is to be disposed of. The post-treatment tape 50 is a strip-shaped fastening tape, and is provided on the outer surface of the back waist portion 4 of the absorbent article 1. When the absorbent article 1 is to be disposed of, the user tears the connected absorbent article 1 along the side end portion 34 of the ventral waist portion 3 and the side end portion 44 of the back waist portion 4, rolls the absorbent article 1 so that the top sheet 11 faces inward, and adheres the post-treatment tape 50 to the outer surface of the absorbent article 1. This holds the absorbent article 1 in a rolled state. The post-treatment tape 50 may be provided on the ventral waist portion 3 or the exterior sheet 13, as long as it is on the outer surface of the absorbent article 1.

[0054] Fig. 6 is a cross-sectional view of the post-treatment tape. As shown in Fig. 6, the post-treatment tape 50 has a lower layer 51 fixed to the outer surface of the back waistband portion 4, an upper layer 53 having an adhesive surface 53a to be adhered to the outer surface of the absorbent article 1 in a rolled state, and an intermediate layer 52 connecting the lower layer 51 and the upper layer 53, and is folded in three so that the lower layer 51, the intermediate layer 52, and the upper layer 53 overlap each other in the thickness direction. Note that, for convenience, in Fig. 6, the lower layer 51, the intermediate layer 52, and the upper layer 53 are illustrated as being separated from each other in the thickness direction, but in reality, the lower layer 51, the intermediate layer 52, and the upper layer 53 may be in contact with each other in the thickness direction.

[0055] The lower layer 51, the intermediate layer 52, and the upper layer 53 are made of a resin film. Adhesive surfaces 51a, 52a, and 53a are formed on one surface of the lower layer 51, the intermediate layer 52, and the upper layer 53, respectively. Non-adhesive surfaces 51b, 52b, and 53b are formed on the other surface of the lower layer 51, the intermediate layer 52, and the upper layer 53, respectively, where no adhesive is applied.

[0056] The adhesive surface 51a of the lower layer 51 is adhered to the outer surface of the back-side waistband portion 4. The intermediate layer 52 is disposed so as to overlap the lower layer 51 from the skin-facing side Z1. The adhesive surface 52a of the intermediate layer 52 is releasably adhered to the non-adhesive surface 51b of the lower layer 51. The upper layer 53 is disposed so as to overlap the intermediate layer 52 from the skin-facing side Z1. The adhesive surface 53a of the upper layer 53 is releasably adhered to the non-adhesive surface 52b of the intermediate layer 52.

[0057] A tab 54 is provided at an end of the post-treatment tape 50. One side of the tab 54 is formed with an adhesive surface 54a coated with an adhesive, and the other side of the tab 54 is formed with a non-adhesive surface 54b to which no adhesive is applied. The adhesive surface 54a of the tab 54 is adhered to the adhesive surface 53a of the upper layer 53 on the tip side of the upper layer 53. The tab 54 constitutes an end of the post-treatment tape 50 in the longitudinal direction.

[0058] When the absorbent article 1 is to be disposed of, the absorbent article 1 is rolled up so that the topsheet 11 faces inward, and then the user pinches and pulls the upper layer 53 and gripping portion 54 of the post-treatment tape 50, causing the adhesive surface 53a of the upper layer 53 to be peeled off from the non-adhesive surface 52b of the intermediate layer 52 and the adhesive surface 52a of the intermediate layer 52 to be peeled off from the non-adhesive surface 51b of the lower layer 51, thereby stretching the post-treatment tape 50. Then, the adhesive surface 53a of the upper layer 53 of the stretched post-treatment tape 50 is adhered to the outer surface of the rolled up absorbent article 1, and the absorbent article 1 is maintained in a rolled up state.

[0059] As shown in FIG. 5, the post-treatment tape 50 has a decorative element 60 drawn on it. The decorative element 60 is a decoration consisting of a character string, a figure, a pattern, a character illustration, a photograph, or a combination of these drawn on the absorbent article 1 so as to be visible from the outside. For example, the decorative element 60 may include two or more elements of a character string, a figure, and a character illustration, and these two or more elements may be drawn so as to be adjacent to each other or overlap each other. The decorative element 60 is a decoration that induces positive emotions in the user. Positive emotions refer to a feeling that daily efforts are recognized and appreciated by the wearer, etc., and that the mind and body are warmed and relieved, healed, or smiled. The decorative element 60 can also be said to be a message expressing positive emotions such as gratitude, love, joy, happiness, and satisfaction from the wearer, the manufacturer of the absorbent article 1, or the character drawn on the absorbent article 1 to the user. The decorative element 60 is drawn with a colorant that does not change color when it comes into contact with moisture. Typically, the decorative element 60 is printed on the upper layer 53 of the post-treatment tape 50.

[0060] 7(a) to 7(c) are plan views showing an exemplary post-processing tape 50. On the post-processing tape 50 shown in FIG. 7(a), a character string "Thank you" written in a handwritten font is printed as a decorative element 60A. On the post-processing tape 50 shown in FIG. 7(b), a character string "I love you" written in a handwritten font is printed as a decorative element 60B. On the post-processing tape 50 shown in FIG. 7(c), a decorative element 60C including the character string "I love you" and an illustration of a character is drawn. The character string and the design of the decorative element 60C are drawn adjacent to each other on the post-processing tape 50. Note that these character strings and designs may be drawn so as to overlap each other. In the following description, the decorative elements 60A, 60B, and 60C are referred to as the decorative element 60 unless there is a need to distinguish them.

[0061] For a user who is raising or caring for a child, changing the absorbent article 1 is one of the tasks that places a particularly large physical or psychological burden. By drawing the decorative element 60 on the post-treatment tape 50, the user can see the decorative element 60 every time the absorbent article 1 is changed. When the user sees the decorative element 60, the user feels that their daily efforts are recognized and appreciated by the wearer, and their self-esteem improves. This can contribute to reducing the user's stress. Note that the decorative element 60 is not limited to the examples shown in Figs. 7(a) to (c) as long as it is a decoration that causes positive feelings in the user. For example, the decorative element 60 may include the character strings "happy," "hug," "good job," "thank you for your hard work," or "happiness."

[0062] 7(a) to 7(c), when the decorative element 60 includes a character string, it is preferable that the entire character string of the decorative element 60 is disposed on the post-processing tape 50. This is because if the character string is not contained within the post-processing tape 50 and is interrupted midway, it becomes difficult to recognize the meaning of the character string. However, if at least 70% or more of the character string in the width direction is disposed within the post-processing tape 50, it is possible to recognize the character string.

[0063] The decorative element 60 has a line width that improves the visibility of the user. When the decorative element 60 includes a character string, the line width of the decorative element 60 means the minimum width of the lines that make up each character. When the decorative element 60 includes a design, the line width of the decorative element 60 means the minimum width of the lines that draw the design. The line width of the decorative element 60 may be larger than the thickness of the fibers of the nonwoven fabric that makes up the exterior sheet 13. For example, the line width of the decorative element 60 is 0.2 mm to 0.9 mm. The fiber thickness of a typical nonwoven fabric is 14 μm to 16 μm.

[0064] The decorative element 60 may be drawn with a coloring agent of the same color as the color of the end (tab portion 54) of the post-treatment tape 50. For example, the tab portion 54 and the decorative element 60 are colored blue. By making the color of the decorative element 60 the same as the color of the tab portion 54, a sense of visual unity is achieved, and the design of the absorbent article 1 can be improved. In addition, the decorative element 60 may be drawn with a coloring agent of a different color than the color of the tab portion 54. By drawing the decorative element 60 in a color different from the color of the tab portion 54, the decorative element 60 becomes more noticeable due to the color contrast, and the visibility of the decorative element 60 can be improved.

[0065] As described above, in the absorbent article 1 according to the above embodiment, the decorative element 60 that induces positive feelings in the user is depicted on the post-disposal tape 50. The post-disposal tape 50 is used to roll up the absorbent article 1 when the absorbent article 1 is disposed of. Therefore, the user will see the decorative element 60 when changing diapers, and will have more opportunities to touch the decorative element 60. This can improve the user's sense of self-affirmation and reduce the user's stress.

[0066] The absorbent article according to one embodiment may include a plurality of post-treatment tapes, each of which may have a decorative element drawn thereon. For example, the absorbent article 101 shown in FIG. 8 includes a pair of post-treatment tapes 50a, 50b arranged at both ends of the ventral waist portion 3 in the waist circumference direction of the wearer. The pair of post-treatment tapes 50a, 50b are adhered to the outer surface of the absorbent article 1 and hold the absorbent article 1 in a rolled-up state. The pair of post-treatment tapes 50a, 50b may be arranged at both ends of the dorsal waist portion 4 in the waist circumference direction.

[0067] The pair of post-processing tapes 50a and 50b are respectively depicted with decorative elements 60D and 60E. In the embodiment shown in FIG. 8, a character string "Always" is printed as the decorative element 60D on the post-processing tape 50a, and a character string "Thank you" is printed as the decorative element 60E on the post-processing tape 50b. The decorative elements 60D and 60E form an integrated character string, such as a phrase or sentence that evokes positive emotions. Each of the decorative elements 60D and 60E may be a character string that evokes positive emotions.

[0068] Also, the decorative element 60 may be drawn at a position other than the post-treatment tape 50, so long as it is drawn with a coloring agent that does not discolor when in contact with moisture. In this case, the decorative element 60 is preferably placed at a position that does not overlap with the stretchable elastic member to avoid reduced visibility due to wrinkles. For example, the decorative element 60 is placed at a position that does not overlap with the leg elastic member 40, the abdominal elastic member 33, and the back elastic member 43.

[0069] For example, the decorative element 60 may be printed on the exterior sheet 13 so as to overlap the cut region 35 of the ventral waist portion 3 or the back waist portion 4. In the region where the abdominal stretch member 33 or the back stretch member 43 is arranged, wrinkles will occur due to contraction of the abdominal stretch member 33 or the back stretch member 43, so arranging the decorative element 60 in this region may reduce the visibility of the decorative element 60. In contrast, by arranging the decorative element 60 so as to overlap the cut region 35, it is possible to suppress the reduction in visibility of the decorative element 60 due to wrinkles.

[0070] 7(a) to (c), the decorative element 60 is drawn on the upper layer 53 of the post-treatment tape 50, but the decorative element 60 may be drawn on the lower layer 51 of the post-treatment tape 50. In this case, the upper layer 53 may have a concealing function that reduces the visibility of the decorative element 60 so that the decorative element 60 can be seen when the upper layer 53 is peeled off. For example, substantially the entire surface of the upper layer 53 may be colored to conceal the decorative element 60 printed on the lower layer 51.

[0071] In one embodiment, as shown in FIG. 9(a), the upper layer 53 of the post-treatment tape 50 may be decorated with a concealing element 70 that reduces the visibility of the decorative element 60 printed on the lower layer 51. The concealing element 70 is, for example, a decoration of the same character string, figure, pattern, illustration, photograph, or combination thereof as the decorative element 60, and overlaps with the decorative element 60 drawn on the lower layer 51 or the intermediate layer 52. The concealing element 70 is drawn with a colorant of a similar color (e.g., white) to the color of the back waist portion 4. That is, the color difference between the back waist portion 4 and the concealing element 70 is smaller than the color difference between the back waist portion 4 and the decorative element 60. This makes the concealing element 70 less noticeable, thereby reducing the visibility of the decorative element 60.

[0072] When the user peels off the upper layer 53 of the post-treatment tape 50 when disposing of the absorbent article 1, the lower layer 51 is exposed and the decorative element 60 becomes visible, as shown in FIG. 9(b). As described above, by making the decorative element 60 visible when the upper layer 53 of the post-treatment tape 50 is peeled off, it is possible to give a surprise to a user who does not expect the display of the decorative element 60. The unexpected display of the decorative element increases the user's joy and is likely to cause positive emotions in the user. As a result, it is possible to improve the user's self-affirmation and effectively reduce the user's stress. The decorative element 60 may be drawn on the middle layer 52 of the post-treatment tape 50.

[0073] (Method of manufacturing absorbent articles) Next, a method for manufacturing the absorbent article 1 will be described. Fig. 10 is a flowchart showing a method for manufacturing the absorbent article 1 according to one embodiment. As shown in Fig. 10, in the method for manufacturing the absorbent article 1 according to one embodiment, first, a decorative film 76 is manufactured (step ST1).

[0074] FIG. 11 is a diagram showing an exemplary decorative film 76. As shown in FIG. 11, the decorative film 76 is a strip-shaped resin film extending in the longitudinal direction D1 and folded into three in the transverse direction D2. By dividing this decorative film 76 in the longitudinal direction D1, a plurality of post-treatment tapes 50 are formed. The decorative film 76 includes a plurality of regions 77 arranged in the longitudinal direction D1, and a decorative element 60 is drawn in one or some of the plurality of regions 77. The decorative film 76 shown in FIG. 11 is printed with a first decorative element 60A including a character string "Thank you" and a second decorative element 60B including a character string "I love you."

[0075] Next, the decorative film 76 is divided into a plurality of regions 77 to form a plurality of post-processing tapes 50 (step ST2). As a result, a post-processing tape 50 having the first decorative element 60A, a post-processing tape 50 having the second decorative element 60B, and a post-processing tape 50 having neither the first decorative element 60A nor the second decorative element 60B are manufactured.

[0076] Next, the post-processing tape 50 having the first decorative element 60A is fixed to a first absorbent article 1 of the plurality of absorbent articles 1 (step ST3). Next, the post-processing tape 50 having the second decorative element 60B is fixed to a second absorbent article 1 of the plurality of absorbent articles 1 (step ST4). Similarly, the post-processing tape 50 not having the first decorative element 60A and the second decorative element 60B is fixed to the other absorbent articles 1. Note that steps ST3 and ST4 may be performed simultaneously.

[0077] Next, a plurality of absorbent articles 1 including the first and second absorbent articles 1 are contained in a package and packaged (step ST5). According to the above-described manufacturing method, a plurality of absorbent articles 1 including the absorbent article 1 having the first decorative element 60A and the second decorative element 60B can be manufactured.

[0078] (packaging) Next, a packaging body 90 for housing a plurality of absorbent articles 1 will be described. Fig. 12 is a front view of the packaging body 90 according to one embodiment, and Fig. 13 is a side view of the packaging body 90. The packaging body 90 includes a packaging sheet 91 for packaging a plurality of absorbent articles 1. The packaging sheet 91 is formed, for example, in a bag shape having a substantially rectangular parallelepiped shape when housing a plurality of absorbent articles 1. The packaging sheet 91 is made of a synthetic resin, for example, polyethylene, polypropylene, or polyethylene terephthalate. As shown in Fig. 13, the packaging body 90 may house a plurality of absorbent articles 1 stacked in multiple stages.

[0079] The plurality of absorbent articles 1 contained in the packaging body 90 includes absorbent articles 1 having decorative elements 60. Although not limited thereto, the proportion of absorbent articles 1 having decorative elements 60 in the entire plurality of absorbent articles 1 contained in the packaging body 90 may be, for example, 30% or less, 20% or less, or 10% or less. By reducing the proportion of absorbent articles 1 having decorative elements 60, the user's joy upon seeing the decorative elements 60 increases, and the decorative elements 60 are more likely to induce positive emotions in the user.

[0080] Furthermore, the packaging body 90 may contain absorbent articles 1 having multiple types of decorative elements 60. For example, the packaging body 90 may contain a first absorbent article 1 having a first decorative element 60A including a character string "Thank you" and a second absorbent article 1 having a second decorative element 60B including a character string "I love you." By displaying the first decorative element 60A and the second decorative element 60B including different character strings to the user, it is possible to more effectively induce positive emotions in the user.

[0081] As shown in FIG. 12, an identification mark 92 for identifying the product may be printed on the outer surface of the packaging body 90 so as to be visible from the outside. The identification mark 92 is, for example, a brand name or a brand logo. Also, as shown in FIG. 10, a decorative element 60 of the absorbent article 1 may be drawn on the outer surface of the packaging body 90. For example, a first decorative element 60A and a second decorative element 60B are drawn on the outer surface of the packaging body 90 shown in FIG. 12. By drawing the first decorative element 60A and the second decorative element 60B on the outer surface of the packaging body 90, the user can recognize that the absorbent article 1 having the first decorative element 60A and the absorbent article 1 having the second decorative element 60B are contained in the packaging body 90 without opening the packaging body 90.

[0082] (Package group) 14 is a diagram showing a packaging group 100 including a packaging body 90 and a packaging body 95. An identification mark 92 for identifying the product is printed on the packaging body 90 and the packaging body 95. The identification mark 92 printed on the packaging body 90 and the packaging body 95 is a brand logo indicating the same brand name. The packaging body 90 contains a plurality of pants-type absorbent articles 1 described above. On the other hand, the packaging body 95 contains a plurality of absorbent articles 201 having a shape different from that of the absorbent article 1.

[0083] Fig. 15 is a plan view showing an example of an absorbent article 201 contained in the packaging body 95. The absorbent article 201 shown in Fig. 15 is a tape-type disposable diaper, and includes an absorbent main body 203 including an absorbent body 202, and a pair of fastening tabs 204 extending laterally from the absorbent main body 203.

[0084] The absorbent body 203 is formed with an indicator 205 that changes color when it comes into contact with moisture. The indicator 205 is disposed at a position overlapping the absorbent body 202 when viewed from the thickness direction, and is provided on the absorbent body 203 so as to be visible from the non-skin side. The indicator 205 changes color when it reacts with bodily fluid absorbed in the absorbent body 14. The color change of the indicator 205 allows the user to know the wetness of the absorbent body 202. The absorbent article 201 also has a decorative element 260 that induces positive emotions in the user. The decorative element 260 is disposed at a position overlapping the absorbent body 202 of the absorbent body 203 when viewed from the thickness direction, and is provided on the absorbent body 203 so as to be visible from the non-skin side. The decorative element 260 changes color when it comes into contact with moisture. For example, the decorative element 260 changes color when it reacts with bodily fluid absorbed in the absorbent body 14, and displays a character string such as "Thank you" or "I love you."

[0085] The decorative element 60 of the absorbent article 1 is disposed on the post-treatment tape 50 (see FIG. 5), whereas the decorative element 260 of the absorbent article 201 is disposed at a position overlapping the absorbent body 202 of the absorbent main body 203 (see FIG. 15). That is, the decorative element 60 of the absorbent article 1 and the decorative element 260 of the absorbent article 201 are disposed at different positions. Note that, in one embodiment, the decorative element 260 is drawn with a colorant that does not discolor in contact with moisture, and may be disposed on the fastening tab 204 of the absorbent article 201.

[0086] Even if the products are of the same brand, the pants-type absorbent article 1 and the tape-type absorbent article 101 have different disposal procedures, and therefore the positions that users pay attention to when disposing of the absorbent articles are different. In the packaging group 100, the decorative elements 60, 260 are arranged at different positions according to the shape of the absorbent article 1, 201, thereby improving the visibility of the decorative elements 60, 260. Note that, in one embodiment, the packaging body 90 and the packaging body 95 may house absorbent articles of the same shape (e.g., pants-type) but different sizes. Even in this case, the decorative elements 60, 260 are arranged at different positions according to the size of the absorbent article.

[0087] Although various embodiments of the absorbent article 1, the manufacturing method of the absorbent article 1, the package 90, and the package group 100 have been described above, the present invention is not limited to the above-mentioned embodiments and various modifications can be made without departing from the spirit of the invention. In other words, it should be noted that the above-mentioned embodiments are intended as illustrative examples and do not limit the scope of the present invention.

[0088] For example, the decorative element 60 is not limited to a character string, and may be a figure, a picture, an illustration, a photograph, or a combination of these. For example, a character string that evokes positive emotions may be written on a designed figure, or only an illustration that evokes positive emotions may be drawn without including a character string.

[0089] Furthermore, the post-treatment tape 50 does not have to be an adhesive fastening tape, and may be, for example, a mechanical fastener that can be joined to the outer surface of the absorbent article 1. The various embodiments described above can be combined to the extent that there is no contradiction.
