[0005] Patent Document 1: Japanese Patent No. 6949805 Summary of the Invention

[0006] The problem the invention aims to solve

[0007] Users of absorbent materials (e.g., parents or caregivers) often experience physical or psychological burdens due to daily childcare or care. The aforementioned diapers display information that evokes positive emotions after the wearer (e.g., the child or the person being cared for) urinates, boosting the user's self-affirmation and reducing stress. However, the aforementioned diapers only display information after the wearer urinates. Additionally, depending on the location of urination, sometimes the indicator may not be wetted and therefore will not display information.

[0008] Therefore, the object of the present invention is to provide an absorbent article that can effectively reduce the stress of a user, a method for manufacturing the absorbent article, a packaging body, and a packaging body assembly.

[0009] Solution for solving the problem

[0010] One absorbent article is an underwear-type absorbent article, comprising: an absorbent body having an absorbent core; a flank waistband connected to one end of the absorbent body along its length; and a back waistband connected to the other end of the absorbent body along its length. This absorbent article has decorative elements that evoke positive emotions in the user, and these decorative elements are painted with a colorant that does not change color upon contact with moisture.

[0011] In the absorbent article of this technical solution, the decorative elements that evoke positive emotions in the user are painted with a colorant that does not change color upon contact with water, thus ensuring the decorative elements remain visible regardless of whether urination has occurred. Therefore, this enhances the user's sense of self-confidence and effectively reduces their stress.

[0012] Alternatively, the absorbent body may have an indicator that changes color upon contact with moisture, with the decorative element positioned where it does not overlap with the indicator. By positioning the decorative element where it does not overlap with the indicator, the visibility of the decorative element can be prevented from being reduced due to the indicator changing color during urination.

[0013] Alternatively, the absorbent body may have a non-woven fabric outer sheet disposed on the non-skin-facing side of the absorbent body, with the line width of the decorative element being greater than the thickness of the fibers in the non-woven fabric constituting the outer sheet. By increasing the line width of the decorative element, its visibility can be improved.

[0014] Alternatively, the absorbent article may have a second decorative element positioned outside the first decorative element, which contains markings that evoke positive emotions in the user and is painted with a colorant that does not change color upon contact with moisture. By painting both the first and second decorative elements on the absorbent article, the user's opportunities to come into contact with the markings that evoke positive emotions are increased. As a result, the user's sense of self-affirmation can be further enhanced.

[0015] Alternatively, the absorbent article may also include a stretchable elastic member, with the decorative element positioned where it does not overlap with the elastic member. In areas where the elastic member is located, wrinkles are created due to the contraction of the elastic member. By positioning the decorative element where it does not overlap with the elastic member, the reduced visibility of the decorative element due to wrinkles can be prevented.

[0016] Alternatively, the abdominal and back waistbands may have waistband stretching members that can extend and retract in the direction of the wearer's waist, with decorative elements positioned where they do not overlap with the waistband stretching members. By positioning the decorative elements where they do not overlap with the waistband stretching members, it is possible to prevent a decrease in the visibility of the decorative elements due to wrinkles caused by the contraction of the waistband stretching members.

[0017] Alternatively, absorbent items may also include a finishing strip to keep the absorbent item rolled up when discarded, with decorative elements depicted on the finishing strip. For parents or caregivers, diaper changing is one of the most physically and psychologically demanding tasks. By depicting decorative elements on the finishing strip, users will see and interact with these elements while changing diapers, increasing their exposure and effectively reducing stress.

[0018] Alternatively, the decorative elements can be placed entirely on the post-processing strip. In this case, the visibility of the decorative elements is improved.

[0019] In one technical solution, the decorative element may include a text string that evokes positive emotions in the user, and the entire text string is positioned on the post-processing band. By positioning the entire text string on the post-processing band, the user can easily identify the text string.

[0020] Alternatively, the ends of the post-treatment strip along its length can be colored, and decorative elements can be depicted using a colorant of the same color as the ends of the post-treatment strip. By making the color of the decorative elements the same as the color of the ends of the post-treatment strip, a sense of visual unity can be achieved, enhancing the design appeal of absorbent items.

[0021] Alternatively, the ends of the post-processing tape along its length can be colored, and decorative elements can be depicted with a colorant of a different color than the ends of the post-processing tape. By depicting decorative elements with a color different from the ends of the post-processing tape, the decorative elements become more conspicuous due to the color contrast. As a result, the visibility of the decorative elements can be improved.

[0022] Alternatively, it may also include a pair of post-processing strips for holding the absorbent material in a rolled-up state when discarded. A first decorative element is disposed on one of the post-processing strips, and a second decorative element is disposed on the other. By depicting the first and second decorative elements on the pair of post-processing strips, the user's opportunity to come into contact with markings that evoke positive emotions is increased. As a result, user stress can be effectively reduced.

[0023] Alternatively, decorative elements can include two or more elements from text strings, graphics, and character illustrations, depicted adjacently or overlapping each other in the post-processing area. By displaying decorative elements containing at least two of these elements, they become more prominent and evoke positive emotions in the user. Consequently, user stress can be effectively reduced.

[0024] Alternatively, the post-processing tape may include: a lower layer fixed to the back waist section; an upper layer having an adhesive surface that adheres to the outer surface of the rolled-up absorbent material; and an intermediate layer connecting the lower and upper layers. The upper and intermediate layers are arranged to overlap the lower layer in the thickness direction. Decorative elements are depicted on either the lower or intermediate layer, and the upper layer has a masking function that reduces the visibility of these decorative elements. When the upper layer has a masking function, the decorative elements depicted on the lower or intermediate layer will be revealed when the upper layer is peeled off to keep the absorbent material rolled up. The unexpected display of decorative elements enhances the user's pleasure and easily evokes positive emotions.

[0025] Alternatively, a masking element that reduces the visibility of the decorative element can be depicted on the upper layer, with the color difference between the back waist section and the masking element being smaller than the color difference between the back waist section and the decorative element. By reducing the color difference between the back waist section and the masking element, the visibility of the decorative element can be reduced.

[0026] In one technical solution, a method for manufacturing an absorbent article in the form of underwear is provided. The absorbent article comprises: an absorbent body having an absorbent core; a flank waistband connected to one end of the absorbent body along its length; a back waistband connected to the other end of the absorbent body along its length; and a finishing strip fixed to the back waistband. The method for manufacturing the absorbent article includes: dividing a decorative film containing a first decorative element that evokes positive emotions in the user to form a finishing strip having the first decorative element; and fixing the finishing strip having the first decorative element to the back waistband of the first absorbent article.

[0027] In the manufacturing method of the above-described technical solution, an absorbent article in the form of underwear is manufactured, wherein the absorbent article has a first decorative element that evokes positive emotions in the user. Based on this absorbent article, by displaying the first decorative element, the user's sense of self-affirmation is enhanced, and the user's stress can be effectively reduced.

[0028] Alternatively, the decorative film may also include a second decorative element that evokes positive emotions in the user, different from the first decorative element. The method of manufacturing the absorbent article further includes: dividing the decorative film to form a post-treatment strip having the second decorative element; and fixing the post-treatment strip having the second decorative element to the back side waist portion of the second absorbent article. Based on this absorbent article, it is possible to manufacture a first absorbent article having the first decorative element and a second absorbent article having the second decorative element.

[0029] In one technical solution, a packaging body for storing multiple absorbent items is provided. The multiple absorbent items are underwear-type absorbent items, comprising: an absorbent body having an absorbent core; a flank waistband connected to one end of the absorbent body along its length; and a back waistband connected to the other end of the absorbent body along its length. The multiple absorbent items include: a first absorbent item having a first decorative element that evokes positive emotions in the user; and a second absorbent item having a second decorative element that evokes positive emotions in the user. The first and second decorative elements comprise distinct text strings or graphics, depicted with a colorant that does not change color upon contact with moisture.

[0030] In this technical solution, the first absorbent article and the second absorbent article are decorated with a first decorative element and a second decorative element that will not change color upon contact with moisture, so that the first decorative element and the second decorative element can be displayed regardless of whether urination occurs. This enhances the user's sense of self-confidence and effectively reduces the user's stress.

[0031] Alternatively, the first or second decorative element may be depicted on the outer surface of the packaging. In this case, even without opening the packaging, the user can identify that the absorbent item with the first or second decorative element is stored inside the packaging.

[0032] A packaging assembly comprises: a first packaging body that houses a first absorbent article having a first shape or a first size; and a second packaging body that houses a second absorbent article having a second shape or a second size. The first and second packaging bodies display the same brand name, and decorative elements that evoke positive emotions in the user are depicted in different positions on the first and second absorbent articles. For this packaging assembly, even if it is from the same brand, the decorative elements are arranged in different positions, thus avoiding uniformity and making the positive emotions evoked by the decorative elements more likely to be lasting. Furthermore, even if the first and second absorbent articles have different sizes, if they are absorbent articles from the same brand and contain decorative elements, the positive emotions evoked by the decorative elements can still be achieved even if the size is changed.

[0033] The effects of the invention

[0034] According to the various technical solutions of the present invention, the stress on users can be effectively reduced. Attached Figure Description

[0050] The following is a reference to the appendix. Figure 1 The embodiments of the present invention will be described in detail below. In the description of the accompanying drawings, the same reference numerals are used for the same elements, and repeated descriptions are omitted. For ease of understanding, some parts may be simplified or exaggerated in the drawings, and the scale is not limited by the description in the drawings.

[0051] The absorbent article 1 according to one embodiment will be described below. Figure 1 This is a perspective view of an absorbent article 1 according to one embodiment. Figure 2 This is a top view of absorbent material 1 viewed from the skin side (Z1). Figure 3 This is a top view of the absorbent material 1 viewed from the non-skin side Z2. Figure 4 This is a cross-sectional view of absorbent item 1. Figures 1-4 The absorbent item 1 shown is a disposable underwear-type diaper that absorbs the wearer's urine.

[0052] exist Figure 2 and Figure 3This refers to the unfolded state of the absorbent material 1, where the absorbent material 1 is cut at the side end 34 of the abdominal waist portion 3 and the side end 44 of the back waist portion 4 (described later), and stretched until no wrinkles are formed. The skin-side Z1 refers to the side facing the wearer's skin when wearing the absorbent material 1, and the non-skin-side Z2 refers to the side facing the opposite side of the wearer's skin when wearing the absorbent material 1. In the following description, the person wearing the absorbent material 1 is referred to as the "wearer," and the person who enables the wearer to wear the absorbent material 1 is referred to as the "user." Typically, the wearer is a child or a caregiver, and the user is a parent or caregiver. In the following description, unless otherwise specified, the positional relationships in the unfolded state will be explained.

[0053] like Figure 2 and Figure 3 As shown, the absorbent article 1 extends along the transverse direction (X) and the longitudinal direction (Y) when unfolded. The longitudinal direction (Y) is the length direction extending between the wearer's ventral and back sides when wearing the absorbent article 1. The transverse direction (X) is a direction orthogonal to the longitudinal direction (Y) and is the width direction extending along the wearer's left-right direction when wearing the absorbent article 1. The thickness direction (Z) is a direction orthogonal to both the transverse direction (X) and the longitudinal direction (Y). In the following description, one end of the absorbent article 1 along the longitudinal direction (Y) is sometimes referred to as the ventral side, and the other end as the back side.

[0054] The absorbent article 1 comprises: a ventral waist portion 3, a dorsal waist portion 4, and an absorbent body 10. The absorbent body 10 has a generally rectangular planar shape that is longer in the longitudinal direction Y of the absorbent article 1. Figure 2 and Figure 3 As shown, the absorbent body 10 includes: a ventral region 10a disposed at one end of the longitudinal Y direction, a dorsal region 10b disposed at the other end of the longitudinal Y direction, and a crotch region 10c disposed in the longitudinal Y direction between the ventral region 10a and the dorsal region 10b.

[0055] On the ventral region 10a of the absorbent body 10, a ventral waistband 3 is joined from the non-skin side Z2. On the dorsal region 10b of the absorbent body 10, a dorsal waistband 4 is joined from the non-skin side Z2. For the absorbent article 1, the absorbent body 10 is folded in half with the ventral waistband 3 and the dorsal waistband 4 facing each other, and the transverse X-shaped side end 34 of the ventral waistband 3 and the transverse X-shaped side end 44 of the dorsal waistband 4 are joined, thereby connecting the ventral waistband 3 and the dorsal waistband 4 into a strip. Thus, as... Figure 1As shown, the absorbent article 1 is formed in the form of underwear. In the following description, the state in which the abdominal waistband 3 and the back waistband 4 are connected into a strip as described above is referred to as the "connected state". In the connected state, the absorbent article 1 has a waistband opening BH for the wearer's waist to pass through, and a pair of leg openings LH for the wearer's legs to pass through.

[0056] The abdominal waist section 3 has a generally rectangular planar shape with the transverse X of the absorbent article 1 as its length direction, and is positioned closer to the non-skin side Z2 than the abdominal region 10a of the absorbent body 10. The abdominal waist section 3 includes: a skin sheet 31 disposed on the skin side Z1, a non-skin sheet 32 ​​disposed on the non-skin side Z2, and a plurality of waist stretching members 33. Typically, the skin sheet 31 and the non-skin sheet 32 ​​are made of plain white nonwoven fabric. For example, the skin sheet 31 and the non-skin sheet 32 ​​are made of SMS nonwoven fabric, spunbond nonwoven fabric, hot-air nonwoven fabric, or a laminate of these nonwoven fabrics formed by sequentially layering spunbond, meltblown, and spunbond nonwoven fabrics. The skin sheet 31 and the non-skin sheet 32 ​​are bonded together by an adhesive such as hot melt adhesive.

[0057] Multiple abdominal stretch members 33 are arranged longitudinally Y-spaced between the skin-facing panel 31 and the non-skin-facing panel 32. These multiple abdominal stretch members 33 extend between the lateral ends 34 of the abdominal waist portion 3 in the transverse X direction. Therefore, the abdominal waist portion 3 stretches transversely X while conforming to the wearer's waistline. The multiple abdominal stretch members 33 are made of elastic materials such as rubber or elastic fibers. Figure 3 As shown, a cutting region 35 is formed in the abdominal waist section 3, at the position overlapping with the absorbent body 14, where there is no abdominal stretch member 33 disposed. In the cutting region 35, a portion of the plurality of abdominal stretch members 33 is cut off midway in the transverse X direction. By forming the cutting region 35, it is possible to suppress the situation where the absorbent body 14 shrinks in the transverse X direction due to the contraction force of the plurality of abdominal stretch members 33.

[0058] The back waist section 4 has a generally rectangular planar shape that is longer in the transverse X direction of the absorbent article 1, and is configured to be closer to the non-skin side Z2 than the back area 10b of the absorbent body 10. The back waist section 4 includes: a skin sheet 41 disposed on the skin side Z1, a non-skin sheet 42 disposed on the non-skin side Z2, and a plurality of back waist extension members 43. Typically, the skin sheet 41 and the non-skin sheet 42 are made of plain white nonwoven fabric. For example, the skin sheet 41 and the non-skin sheet 42 are made of SMS nonwoven fabric, spunbond nonwoven fabric, hot air nonwoven fabric, or a laminate of these nonwoven fabrics formed by sequentially layering spunbond, meltblown, and spunbond nonwoven fabrics. The skin sheet 41 and the non-skin sheet 42 are bonded to each other by an adhesive such as hot melt adhesive.

[0059] Multiple back band stretch members 43 are arranged longitudinally Y-spaced between the skin-facing panel 41 and the non-skin-facing panel 42. The multiple back band stretch members 43 extend between the side ends 44 in the transverse X direction of the back waistband 4. Therefore, the back waistband 4 stretches in the transverse X direction while conforming to the wearer's waist. The multiple back band stretch members 43 are made of elastic materials such as rubber or elastic fibers. Figure 3 As shown, in the back waist section 4, a cutting area 35 is formed at the position overlapping with the absorbent body 14, where multiple back waist stretch members 43 are disposed. That is, in the cutting area 35, a portion of the multiple back waist stretch members 43 is cut off midway in the transverse X direction. By forming the cutting area 35, it is possible to suppress the situation where the absorbent body 14 shrinks in the transverse X direction due to the contraction force of the multiple back waist stretch members 43. The waist stretch member 33 and the back waist stretch member 43 constitute a waist stretch member that can stretch in the direction of the wearer's waist.

[0060] The absorbent body 10 includes a surface sheet 11, a back sheet 12, an outer sheet 13, and an absorbent core 14. The surface sheet 11 is the side of the absorbent body 10 that comes into contact with the wearer and is positioned on the skin-side Z1. The surface sheet 11 is made of a water-permeable nonwoven fabric such as spunbond nonwoven fabric and covers the absorbent core 14 from the skin-side Z1. Typically, the surface sheet 11 is white and plain. Figure 4 As shown, the surface sheet 11 is bonded to the skin-side Z1 of the absorber 14, for example, by means of a hot melt adhesive HM.

[0061] The back sheet 12 is configured to be positioned closer to the non-skin side Z2 than the surface sheet 11. The back sheet 12 is made of a non-permeable film and covers the absorber 14 from the non-skin side Z2. The back sheet 12 is bonded to the surface of the absorber 14 on the non-skin side Z2, for example, by a hot melt adhesive HM.

[0062] The outer sheet 13 is positioned closer to the non-skin side Z2 than the back sheet 12, forming the outermost layer of the absorbent body 10. The outer sheet 13 is, for example, made of a non-permeable nonwoven fabric. Typically, the outer sheet 13 is white and plain. In the transverse direction X, the width of the outer sheet 13 is greater than the width of the back sheet 12, and the outer sheet 13 extends to both sides of the transverse direction X beyond the back sheet 12.

[0063] Absorbent 14 is disposed between the surface sheet 11 and the back sheet 12 of the absorbent body 10 to absorb urine from the wearer that passes through the surface sheet 11. Figure 4As shown, the absorbent body 14 includes an absorbent core 15 and a core-cladding layer 16. The absorbent core 15, for example, comprises pulp fibers and a superabsorbent polymer (SAP) to absorb the wearer's urine. For the pulp of the absorbent core 15, for example, chemical pulp, cellulose fibers, rayon, cellulose acetate, or other cellulose fibers can be used. For the superabsorbent polymer, for example, starch-based, acrylic-based, or amino acid-based particulate or fibrous polymers can be used. The core-cladding layer 16, for example, is composed of thin paper or a non-woven fabric sheet, covering the skin-side Z1 and non-skin-side Z2 of the absorbent core 15. The core-cladding layer 16 is, for example, bonded to the skin-side Z1 and non-skin-side Z2 of the absorbent core 15 using a hot-melt adhesive HM.

[0064] like Figure 2 As shown, the absorbent body 10 has a pair of leak-proof pleats 80. The leak-proof pleats 80 are positioned on the outer side of the transverse X of the absorbent core 15 to prevent urine excreted into the absorbent core 15 from leaking out in the transverse X direction. Figure 4 As shown, the leak-proof pleats 80 are formed by folding the two sides of the outer panel 13 in the left-right direction inward. A pair of leak-proof pleats 80 are upright, three-dimensional pleats and are provided on the absorbent body 10 along the longitudinal direction Y.

[0065] The leak-proof pleat 80 includes: a pair of telescopic members 71 extending along the longitudinal direction Y, an erected portion 81 erected by the contraction of the pair of telescopic members 71, a transverse fixing portion 82 that serves as the erection fulcrum on the transverse direction X of the erected portion 81, and a longitudinal fixing portion 83 that serves as the erection fulcrum on the longitudinal direction Y of the erected portion 81.

[0066] A pair of telescopic members 71 are disposed between the inwardly folded portions of the outer sheet 13, extending longitudinally Y. The pair of telescopic members 71 are, for example, linear or flat rubber capable of contracting in the longitudinal direction. The pair of telescopic members 71 are disposed apart from each other by a longitudinal centerline CW that divides the absorbent body 10 into two parts in the transverse X direction, and are fixed to the outer sheet 13 in a state of elongation along the longitudinal Y direction. The ventral ends of the pair of telescopic members 71 are disposed in ventral region 10a, and the dorsal ends of the pair of telescopic members 71 are disposed in dorsal region 10b.

[0067] The horizontal fixing portion 82 is formed on the outer side of the horizontal X of the upright portion 81 over approximately the entire longitudinal Y region of the absorbent body 10. The horizontal fixing portion 82 is part of the outer mounting piece 13 and is attached to the surface piece 11 or the back piece 12. The attachment of the horizontal fixing portion 82 is achieved, for example, using a hot melt adhesive HM (see reference). Figure 4 The horizontal fixing part 82 becomes the uprighting support point on the horizontal X side of the upright part 81.

[0068] The longitudinal fixing portion 83 is formed on the inner side of the transverse fixing portion 82 in the transverse direction X. The longitudinal fixing portion 83 is part of the outer sheet 13 and is joined to the surface sheet 11 or the back sheet 12. The joining of the longitudinal fixing portion 83 is, for example, using a hot melt adhesive. The longitudinal fixing portion 83 includes a ventral fixing portion 84 disposed in the ventral region 10a and a dorsal fixing portion 85 disposed in the dorsal region 10b. The ventral fixing portion 84 is formed in the longitudinal direction Y between the ventral end 10F of the absorbent body 10 and the ventral end edge 15F of the absorbent core 15. The dorsal fixing portion 85 is formed in the longitudinal direction Y between the dorsal end 10R of the absorbent body 10 and the dorsal end edge 15R of the absorbent core 15. The longitudinal fixing portion 83 serves as the vertical support point of the upright portion 81 in the longitudinal direction Y.

[0069] An upright portion 81 is formed between the ventral fixing portion 84 and the dorsal fixing portion 85. That is, the upright portion 81 is positioned inside the transverse fixing portion 82 in the lateral direction (X) and inside the longitudinal fixing portion 83 in the longitudinal direction (Y). The upright portion 81 is a part of the outer sheet 13 that is not fixed relative to the surface sheet 11 or the back sheet 12. A telescopic member 71 extending in the longitudinal direction (Y) is connected to the upright portion 81. By contracting the telescopic member 71 in the longitudinal direction (Y), the upright portion 81 stands upright with the transverse fixing portion 82 as its starting point. Thus, the upright portion 81 stands upright at the position where the absorbent core 15 is inserted from the transverse direction (X), thereby preventing urine leakage.

[0070] like Figure 2 As shown, the absorbent article 1 also includes a pair of leg-length telescopic members 40 capable of stretching and contracting along its length. The pair of leg-length telescopic members 40 are positioned laterally (X) outwards from the pair of telescopic members 71. The ventral ends of the pair of leg-length telescopic members 40 are located in ventral region 10a, and the dorsal ends are located in dorsal region 10b. The pair of leg-length telescopic members 40 are made of, for example, a stretchable material such as rubber or elastic fiber capable of contracting in the length direction, and are connected to the outer sheet 13 of the absorbent body 10 along the side edge 10S of the absorbent body 10 in a longitudinally (Y) elongated state. When the absorbent article 1 is worn, the pair of leg-length telescopic members 40 contract longitudinally (Y), thereby fitting the side edge 10S of the absorbent body 10 against the wearer's leg circumference.

[0071] like Figure 3 As shown, the absorbent article 1 may also have an indicator 72 that changes color upon contact with moisture. The indicator 72 is positioned overlapping the absorbent body 14 when viewed from the thickness direction Z, and is provided on the outer cover 13 in a manner visible from the non-skin side Z2 of the absorbent body 10. The indicator 72 reacts with bodily fluids absorbed by the absorbent body 14 and changes color. The color change of the indicator 72 allows the user to gauge the degree of wetness of the absorbent body 14.

[0072] Figure 5 This is the rear view of absorbent item 1. (Example) Figure 5 As shown, the absorbent article 1 includes a post-treatment strip 50 for holding the absorbent article 1 in a rolled-up state when it is discarded. The post-treatment strip 50 is a strip-shaped fixing strip provided on the outer surface of the back waist portion 4 of the absorbent article 1. When discarding the absorbent article 1, the user tears the connected absorbent article 1 along the side end 34 of the abdominal waist portion 3 and the side end 44 of the back waist portion 4, rolls up the absorbent article 1 with the surface sheet 11 facing inward, and attaches the post-treatment strip 50 to the outer surface of the absorbent article 1. Thus, the absorbent article 1 is held in a rolled-up state. In addition, the post-treatment strip 50 can be provided only on the outer surface of the absorbent article 1, or it can be provided on the abdominal waist portion 3 or the outer sheet 13.

[0073] Figure 6 This is a cross-sectional view of the post-processing strip. For example... Figure 6 As shown, the post-processing tape 50 has: a lower layer 51 fixed to the outer surface of the back waist section 4; an upper layer 53 having an adhesive surface 53a bonded to the outer surface of the rolled-up absorbent article 1; and an intermediate layer 52 connecting the lower layer 51 and the upper layer 53. The lower layer 51, the intermediate layer 52, and the upper layer 53 are folded into three folds, overlapping each other in the thickness direction. Furthermore, in Figure 6 For convenience, the diagram shows the lower layer 51, the middle layer 52, and the upper layer 53 separated in the thickness direction. In reality, the lower layer 51, the middle layer 52, and the upper layer 53 can also be in contact in the thickness direction.

[0074] The lower layer 51, the middle layer 52, and the upper layer 53 are composed of a resin film. Adhesive surfaces 51a, 52a, and 53a coated with adhesive are formed on one side of the lower layer 51, the middle layer 52, and the upper layer 53, respectively. Non-adhesive surfaces 51b, 52b, and 53b without adhesive coating are formed on the other side of the lower layer 51, the middle layer 52, and the upper layer 53, respectively.

[0075] The adhesive surface 51a of the lower layer 51 is bonded to the outer surface of the back waistband portion 4. The middle layer 52 is arranged to overlap the lower layer 51 from the skin side Z1. The adhesive surface 52a of the middle layer 52 is peelably bonded to the non-adhesive surface 51b of the lower layer 51. The upper layer 53 is arranged to overlap the middle layer 52 from the skin side Z1. The adhesive surface 53a of the upper layer 53 is peelably bonded to the non-adhesive surface 52b of the middle layer 52.

[0076] A gripper 54 is provided at the end of the post-processing belt 50. An adhesive surface 54a coated with adhesive is formed on one side of the gripper 54, and a non-adhesive surface 54b without adhesive is formed on the other side of the gripper 54. The adhesive surface 54a of the gripper 54 is bonded to the adhesive surface 53a of the upper layer 53 at the front end side. The gripper 54 constitutes the end of the post-processing belt 50 in the longitudinal direction.

[0077] When discarding absorbent 1, after rolling up the absorbent 1 with the surface sheet 11 facing inward, the user pinches the upper layer 53 and the gripping part 54 of the post-treatment tape 50 and pulls it, peeling the adhesive surface 53a of the upper layer 53 from the non-adhesive surface 52b of the middle layer 52, and peeling the adhesive surface 52a of the middle layer 52 from the non-adhesive surface 51b of the lower layer 51, thus stretching the post-treatment tape 50. Then, the adhesive surface 53a of the upper layer 53 of the stretched post-treatment tape 50 is bonded to the outer surface of the rolled-up absorbent 1, keeping the absorbent 1 in the rolled-up state.

[0078] like Figure 5 As shown, decorative elements 60 are depicted on the post-processing belt 50. Decorative elements 60 are decorations formed by text strings, graphics, patterns, character illustrations, photographs, or combinations thereof that are externally visible on the absorbent article 1. For example, decorative elements 60 may be depicted as including two or more elements from text strings, graphics, and character illustrations, said two or more elements being adjacent to or overlapping each other. Decorative elements 60 are decorations that evoke positive emotions in the user. Positive emotions refer to feelings of comfort, warmth, relaxation, healing, or satisfaction derived from the wearer's or others recognizing their daily efforts. Alternatively, decorative elements 60 can be described as conveying positive emotions such as gratitude, love, joy, happiness, and satisfaction from the wearer, the manufacturer of the absorbent article 1, or the character depicted on the absorbent article 1. Decorative elements 60 are depicted with a colorant that does not change color upon contact with moisture. Typically, decorative elements 60 are printed on the upper layer 53 of the post-processing belt 50.

[0079] Figure 7 (a) to (c) are top views illustrating the post-processing band 50. Figure 7 The post-processing tape 50 shown in (a) is printed with the text string "Thank you" depicted in a handwritten style font as a decorative element 60A. Figure 7 (b) shows a post-processing strip 50 printed with the text string "I really like it" depicted in a handwritten style font as a decorative element 60B. Figure 7The post-processing tape 50 shown in (c) is decorated with decorative elements 60C containing text strings such as "I really like it" and character illustrations. The text strings and patterns of decorative elements 60C can be drawn adjacent to each other on the post-processing tape 50. In addition, these text strings and patterns can also be drawn overlapping each other. In the following description, unless otherwise specified, decorative elements 60A, 60B, and 60C will be referred to as decorative elements 60.

[0080] For users engaged in childcare or caregiving, changing absorbent pads 1 is one of the most physically and psychologically demanding tasks. By depicting decorative elements 60 on the post-processing tape 50, users will see these decorative elements 60 each time they change absorbent pads 1. Seeing the decorative elements 60 allows users to feel appreciated for their daily efforts, leading to a sense of comfort and increased self-affirmation. This can help reduce user stress. Furthermore, the decorative elements 60 can be anything that evokes positive emotions in the user, and are not limited to any particular type. Figure 7 Examples shown in (a) to (c). For example, decorative element 60 may also include word strings such as “happy”, “hug”, “you’ve worked hard”, “thank you for your hard work”, or “happiness”.

[0081] In addition, such as Figure 7 As shown in (a) to (c), when the decorative element 60 contains a text string, it is preferable that the entire text string of the decorative element 60 is positioned on the post-processing band 50. This is because if the text string is not contained within the post-processing band 50 and is interrupted midway, it is difficult to recognize the meaning of the text string. Furthermore, if at least 70% or more of the text string in the width direction is positioned within the post-processing band 50, the text string can be recognized.

[0082] Decorative element 60 has a line width that ensures good visibility for the user. When decorative element 60 contains a string of text, the line width of decorative element 60 refers to the minimum width of the lines constituting each character. When decorative element 60 contains a pattern, the line width of decorative element 60 refers to the minimum width of the lines depicting the pattern. The line width of decorative element 60 can be greater than the thickness of the fibers of the nonwoven fabric constituting the outer covering sheet 13. For example, the line width of decorative element 60 is 0.2 mm to 0.9 mm. Furthermore, the thickness of fibers in general nonwoven fabrics is 14 μm to 16 μm.

[0083] Decorative element 60 can be painted with a colorant of the same color as the end (handle 54) of the post-processing tape 50. For example, the handle 54 and decorative element 60 are painted blue. By making the color of decorative element 60 the same as the color of handle 54, a sense of visual unity can be achieved, enhancing the design of the absorbent article 1. Alternatively, decorative element 60 can be painted with a colorant of a different color than handle 54. By painting decorative element 60 with a color different from handle 54, decorative element 60 becomes more conspicuous due to color contrast, thus improving its visibility.

[0084] As described above, in the absorbent article 1 of the above embodiment, decorative elements 60 that evoke positive emotions in the user are depicted on the post-treatment belt 50. The post-treatment belt 50 is used when the absorbent article 1 is discarded to roll it up. Therefore, the user will see the decorative elements 60 when changing diapers, increasing the opportunity to come into contact with them. This can enhance the user's sense of self-confidence and reduce user stress.

[0085] Alternatively, one embodiment of the absorbent article may include multiple post-processing strips, each of which is decorated with decorative elements. For example, Figure 8 The absorbent article 101 shown has a pair of finishing straps 50a and 50b disposed at both ends of the abdominal waist portion 3 in the waist direction of the wearer. The pair of finishing straps 50a and 50b are adhered to the outer surface of the absorbent article 1 to keep the absorbent article 1 in a rolled-up state. In addition, the pair of finishing straps 50a and 50b may also be disposed at both ends of the back waist portion 4 in the waist direction.

[0086] Decorative elements 60D and 60E are depicted on a pair of post-processing bands 50a and 50b, respectively. Figure 8 In the illustrated embodiment, the text string "All along" is printed on post-processing tape 50a as decorative element 60D, and the text string "Thank you" is printed on post-processing tape 50b as decorative element 60E. Decorative elements 60D and 60E constitute a single text string that evokes a positive emotion, such as a phrase or sentence. Alternatively, decorative elements 60D and 60E may each be a text string that evokes a positive emotion.

[0087] Alternatively, if the decorative element 60 is painted with a colorant that will not change color upon contact with moisture, it can also be painted in a location other than the post-processing zone 50. In this case, to avoid reduced visibility due to wrinkles, the decorative element 60 is preferably positioned in a location that does not overlap with the stretchable elastic members. For example, the decorative element 60 is positioned in a location that does not overlap with the leg stretch member 40, the waist stretch member 33, and the back stretch member 43.

[0088] For example, the decorative element 60 can also be printed on the outer cover 13 in a manner that overlaps with the cut area 35 of the abdominal waistband 3 or the back waistband 4. In areas where the abdominal or back waistband stretch members 33 are located, wrinkles may form due to the contraction of the abdominal or back waistband stretch members 33. Therefore, if the decorative element 60 is located in such areas, there is a concern that its visibility may be reduced. To address this, by arranging the decorative element 60 in a manner that overlaps with the cut area 35, the reduction in visibility of the decorative element 60 due to wrinkles can be suppressed.

[0089] exist Figure 7 In (a) to (c), decorative elements 60 are depicted on the upper layer 53 of the post-processing belt 50, but decorative elements 60 may also be depicted on the lower layer 51 of the post-processing belt 50. In this case, in order to make the decorative elements 60 visible when the upper layer 53 is peeled off, the upper layer 53 may have a masking function that reduces the visibility of the decorative elements 60. For example, approximately the entire surface of the upper layer 53 may be colored, and the decorative elements 60 printed on the lower layer 51 may be masked.

[0090] In one embodiment, it can also be as follows Figure 9 As shown in (a), an opaque element 70 is depicted on the upper layer 53 of the post-processing belt 50 to reduce the visibility of the decorative element 60 printed on the lower layer 51. The opaque element 70 is, for example, a decoration consisting of the same text, graphics, patterns, illustrations, photographs, or combinations thereof as the decorative element 60, and overlaps with the decorative element 60 depicted on the lower layer 51 or the intermediate layer 52. The opaque element 70 is depicted with a colorant of the same color family as the back side waist portion 4 (e.g., white). That is, the color difference between the back side waist portion 4 and the opaque element 70 is smaller than the color difference between the back side waist portion 4 and the decorative element 60. Thus, the opaque element 70 becomes less conspicuous, thereby reducing the visibility of the decorative element 60.

[0091] When the user peels off the upper layer 53 of the post-treatment belt 50 when discarding absorbent material 1, such as Figure 9 As shown in (b), the lower layer 51 is exposed, making the decorative element 60 visible. As described above, by peeling away the upper layer 53 of the post-processing tape 50, the decorative element 60 is revealed, thereby surprising the user who cannot anticipate its appearance. The unexpected display of the decorative element enhances the user's pleasure and easily evokes positive emotions. As a result, it can boost the user's self-confidence and effectively reduce user stress. Alternatively, the decorative element 60 can also be depicted on the middle layer 52 of the post-processing tape 50.

[0092] (Method for manufacturing absorbent materials)

[0093] Next, the manufacturing method of absorbent article 1 will be explained. Figure 10 This is a flowchart illustrating a method for manufacturing an absorbent article 1 according to one embodiment. For example... Figure 10 As shown, in the manufacturing method of the absorbent article 1 according to one embodiment, a decorative film 76 is first manufactured (step ST1).

[0094] Figure 11 This is a diagram illustrating the decorative film 76. (See diagram for example.) Figure 11 As shown, the decorative film 76 is a strip-shaped resin film extending in the length direction D1 and folded into three folds in the width direction D2. By dividing the decorative film 76 in the length direction D1, a plurality of post-processing strips 50 are formed. The decorative film 76 includes a plurality of regions 77 arranged along the length direction D1, and one or more of these regions 77 are decorated with decorative elements 60. Figure 11 The decorative film 76 shown is printed with a first decorative element 60A containing the text string "thank you" and a second decorative element 60B containing the text string "I like it very much".

[0095] Next, the decorative film 76 is divided into multiple regions 77 to form multiple post-processing strips 50 (step ST2). Thus, post-processing strips 50 having a first decorative element 60A, post-processing strips 50 having a second decorative element 60B, and post-processing strips 50 not having the first decorative element 60A and the second decorative element 60B are manufactured.

[0096] Next, a post-processing strip 50 having the first decorative element 60A is fixed to the first absorbent article 1 among the plurality of absorbent articles 1 (step ST3). Next, a post-processing strip 50 having the second decorative element 60B is fixed to the second absorbent article 1 among the plurality of absorbent articles 1 (step ST4). Similarly, post-processing strips 50 without the first decorative element 60A and the second decorative element 60B are fixed to the other absorbent articles 1. Furthermore, steps ST3 and ST4 can be performed simultaneously.

[0097] Next, multiple absorbent articles 1, including the first absorbent article 1 and the second absorbent article 1, are placed in a packaging body for packaging (step ST5). According to the above manufacturing method, multiple absorbent articles 1, including absorbent articles 1 having the first decorative element 60A and the second decorative element 60B, can be manufactured.

[0098] (Packaging)

[0099] Next, the packaging 90 that holds multiple absorbent items 1 will be described. Figure 12 This is a front view of the packaging body 90 according to one embodiment. Figure 13This is a side view of the packaging body 90. The packaging body 90 includes a packaging sheet 91 for packaging multiple absorbent articles 1. The packaging sheet 91 is, for example, formed into a bag shape with a generally rectangular parallelepiped shape when containing multiple absorbent articles 1. The packaging sheet 91 is, for example, made of a synthetic resin such as polyethylene, polypropylene, or polyethylene terephthalate. Figure 13 As shown, multiple absorbent items are stacked in multiple layers within the packaging body 90.

[0100] The multiple absorbent items 1 housed within the packaging 90 include absorbent items 1 with decorative elements 60. While not limited, the proportion of absorbent items 1 with decorative elements 60 within the overall collection of multiple absorbent items 1 housed in the packaging 90 may be, for example, less than 30%, less than 20%, or less than 10%. By reducing the proportion of absorbent items 1 with decorative elements 60, the user's pleasure upon seeing the decorative elements 60 increases, easily evoking positive emotions in the user.

[0101] Additionally, the packaging body 90 can hold an absorbent item 1 with various decorative elements 60. For example, the packaging body 90 can hold a first absorbent item 1 with a first decorative element 60A containing the text string "thank you," and a second absorbent item 1 with a second decorative element 60B containing the text string "I really like it." By displaying the first decorative element 60A and the second decorative element 60B containing different text strings to the user, it is possible to more effectively evoke positive emotions in the user.

[0102] like Figure 12 As shown, an identification mark 92 for identifying the product, which can be visually recognized from the outside, can also be printed on the outer surface of the packaging body 90. The identification mark 92 may be, for example, a brand name or brand logo. Alternatively, it may be as follows... Figure 10 As shown, decorative elements 60 of the absorbent article 1 are depicted on the outer surface of the packaging body 90. For example, in Figure 12 The outer surface of the package 90 shown is decorated with a first decorative element 60A and a second decorative element 60B. By depicting the first decorative element 60A and the second decorative element 60B on the outer surface of the package 90, even without opening the package 90, the user can recognize that the package 90 contains an absorbent article 1 with the first decorative element 60A and an absorbent article 1 with the second decorative element 60B.

[0103] (Packaging Group)

[0104] Figure 14This diagram shows a packaging assembly 100 comprising packaging body 90 and packaging body 95. Identification markings 92 for identifying the product are printed on packaging body 90 and packaging body 95. The identification markings 92 printed on packaging body 90 and packaging body 95 are brand logos displaying the same brand name. Packaging body 90 houses multiple absorbent items 1 of the aforementioned underwear type. On the other hand, packaging body 95 houses multiple absorbent items 201 with different shapes from the absorbent items 1.

[0105] Figure 15 This is a top view showing an example of an absorbent article 201 housed in packaging 95. Figure 15 The absorbent article 201 shown is a strip-type disposable diaper, having an absorbent body 203 including an absorbent core 202, and a pair of fastening flaps 204 extending laterally from the absorbent body 203.

[0106] An indicator 205 that changes color upon contact with moisture is formed on the absorbent body 203. The indicator 205 is positioned overlapping the absorbent body 202 when viewed from the thickness direction and is placed on the absorbent body 203 in a manner visible from the non-skin side. The indicator 205 changes color in response to bodily fluids absorbed by the absorbent body 14. The color change of the indicator 205 allows the user to gauge the degree of wetness of the absorbent body 202. Additionally, the absorbent article 201 has a decorative element 260 that evokes positive emotions in the user. The decorative element 260 is positioned overlapping the absorbent body 202 of the absorbent body 203 when viewed from the thickness direction and is placed on the absorbent body 203 in a manner visible from the non-skin side. The decorative element 260 changes color upon contact with moisture. For example, the decorative element 260 changes color in response to bodily fluids absorbed by the absorbent body 14 and displays a message such as "Thank you" or "I really like it."

[0107] The decorative element 60 of the absorbent item 1 is placed on the post-processing belt 50 (see reference). Figure 5 In contrast, the decorative element 260 of the absorbent article 201 is positioned to overlap with the absorbent body 202 of the absorbent body 203 (see reference). Figure 15 That is, the decorative element 60 of the absorbent article 1 and the decorative element 260 of the absorbent article 201 are arranged in different positions. In addition, in one embodiment, the decorative element 260 may be painted with a colorant that does not change color when in contact with water and is arranged on the fastening flap 204 of the absorbent article 201.

[0108] Even for products from the same brand, the order in which absorbent items 1 (like underwear) and 101 (like a belt) are disposed of differs, resulting in different points of focus for the user when disposing of the absorbent items. In the packaging assembly 100, decorative elements 60 and 260 are positioned differently according to the shapes of the absorbent items 1 and 201, enhancing their visibility. Furthermore, in one embodiment, packaging bodies 90 and 95 may contain absorbent items of the same shape (e.g., underwear) but different sizes. Even in this case, decorative elements 60 and 260 are positioned differently according to the size of the absorbent items.

[0109] The absorbent article 1, the method of manufacturing the absorbent article 1, the packaging body 90, and the packaging body assembly 100 according to various embodiments have been described above. However, the present invention is not limited to the above embodiments and can be modified in various ways without changing the essence of the invention. That is, it should be noted that the above embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0110] For example, decorative element 60 is not limited to text strings; it can be any decorative element, such as a graphic, pattern, illustration, photograph, or a combination thereof. For example, a graphic may contain text strings that evoke positive emotions, or an illustration that evokes positive emotions may be depicted without text strings.

[0111] Alternatively, the post-treatment tape 50 may not be an adhesive fastener; for example, it may be a mechanical fastener capable of engaging with the outer surface of the absorbent article 1. The various embodiments described above can be combined without contradiction.
