=== Basic configuration of unfolded diapers ===
FIG. 1 is a plan view for explaining the configuration of the unfoldable diaper 1, and shows the unfolded and extended state of the unfoldable diaper 1. FIG. 2 is a cross-sectional view illustrating the configuration of the unfolded diaper 1. The unfoldable diaper 1 (hereinafter referred to as a diaper) has a longitudinal direction, a width direction, and a thickness direction orthogonal to each other, and a rear waistline portion 1a covering the back side of the wearer, a crotch portion 1b, A front waistline portion 1c covering the abdominal side is aligned in the longitudinal direction. In the longitudinal direction, the rear waistline portion 1a side is referred to as the rear side, the front waistline portion 1c side is referred to as the front side, the side in contact with the wearer in the thickness direction is referred to as the skin side, and the opposite side is referred to as the non-skin side.

  The diaper 1 has a main body 1 ′ in which an absorbent body 4 is provided between a liquid-permeable top sheet 2 (for example, a nonwoven fabric) and a liquid-impermeable back sheet 3 (for example, a resin film). The absorbent body 4 extends in the longitudinal direction from the rear waistline portion 1a to the front waistline portion 1c, and covers the absorbent core 41 (for example, composed of pulverized pulp or high-absorbent polymer) that absorbs and holds excreta. And a liquid-permeable covering material 42 (for example, a tissue sheet or a non-woven fabric). In the present embodiment, the planar shape of the absorber 4 is a rectangle, and the planar shape of the absorber core 41 is an hourglass shape with a narrowed central portion in the longitudinal direction. Moreover, the exterior sheet 5 (for example, nonwoven fabric) which comprises the external shape of the diaper 1 is provided in the non-skin side of the back sheet 3. As shown in FIG. The back sheet 3 and the exterior sheet 5 have the same shape. Although not shown, in order to improve the fit of the waistline, the rear waistline portion 1a and the front waistline portion 1c are provided with stretchable members (for example, stretchable nonwoven fabric and thread rubber) that can be stretched in the width direction. Good.

  In the crotch portion 1b, a crotch stretchable sheet 6 (for example, a stretchable film or a stretchable nonwoven fabric) is provided between the back sheet 3 and the absorbent body 4. Since the absorber 4 shrinks | contracts in the site | part in which the crotch elastic sheet 6 was provided, a flat shape is easy to be maintained. In addition, two pairs of notches 43 facing in the width direction are provided side by side in the longitudinal direction at a portion of the absorber core 41 that overlaps the crotch stretchable sheet 6. The notch 43 makes it easy for the rear waistline portion 1a and the front waistline portion 1c to rise from the flat crotch portion 1b. Therefore, the diaper 1 approaches the shape of a wearer's body, and becomes easy to fit a wearer.

  The rear waistline portion 1a is provided with a pair of fastening tapes 7 extending to both outer sides in the width direction. The fastening tape 7 is provided with a hook sheet 7a (for example, a sheet having a male material for a hook-and-loop fastener), and the hook sheet 7a is a target sheet 8 (see FIG. 4 described later, for example, a female material for a hook-and-loop fastener) provided on the exterior sheet 5. A sheet or a non-woven fabric). The pair of fastening tapes 7 are locked to the target sheet 8 (that is, the non-skin side surface of the front waistline portion 1c), thereby forming one waistline opening WH and a pair of leg hole openings LH (described later). (See FIG. 10).

  The both ends of the diaper 1 in the width direction are constricted at the center in the longitudinal direction, and the constricted portions form leg opening LH. And a pair of leg-holes stretchable sheet 9 (for example, a stretchable film or a stretchable nonwoven fabric) is provided along the longitudinal direction at both outer side portions in the width direction of the diaper 1. The leg-holes stretchable sheet 9 is fixed between the back sheet 3 and the leak-proof wall sheet 21 (described later) in a state of extending in the longitudinal direction of the diaper 1. Therefore, in the diaper 1 in the natural state, both side portions in the width direction forming the leg opening LH can be expanded and contracted in the longitudinal direction. This part that can be expanded and contracted in the longitudinal direction is referred to as a leg-hole expansion / contraction part 10, and the diaper 1 fits the wearer's leg by the leg-hole expansion / contraction part 10, and can suppress the leakage of excrement from the leg opening LH.

  In addition, the site | part which can be expanded-contracted in a longitudinal direction among the site | parts in which the elastic sheet 9 was provided is the leg periphery expansion-contraction part 10, and the site | parts in which the elastic force is not expressed even if it is a site | part in which the elastic sheet 9 was provided Suppose that it does not correspond to the rotation elastic part 10. In the drawing, only the portion where the stretching force is expressed is described among the portions where the stretchable sheet 9 is provided. Further, instead of the elastic sheet 9, one or more thread-like stretchable members (for example, thread-like polyurethane stretchable fibers or thread-like natural rubber) are provided at intervals in the width direction, and the thread-like stretchable member is provided. Of these parts, a part that can be expanded and contracted in the longitudinal direction may be used as a leg-hole expansion / contraction part.

  Moreover, a pair of leak-proof wall sheets 21 are provided on the skin side of the top sheet 2 on both side portions in the width direction of the diaper 1. As shown in FIG. 2, the edge part of the width direction inner side of the leak-proof wall sheet | seat 21 is folded in the non-skin side. Thus, between the leak-proof wall sheet 21 which became two layers, the elastic member 22 for leak-proof walls is being fixed in the state extended in the longitudinal direction. Moreover, as shown in FIG. 1, the leak-proof wall sheet | seat 21 is joined to the top sheet 2 or the diaper main-body part with the adhesive agent in the 1st junction part 23 and the 2nd junction part 24. As shown in FIG. The first joint portion 23 is both ends of the leak-proof wall sheet 21 in the longitudinal direction, and is provided on the inner side in the width direction than the second joint portion 24. In the present embodiment, three first joint portions 23 are arranged in the width direction at each end portion in the longitudinal direction of the leak-proof wall sheet 21. The second joint portion 24 extends from one end in the longitudinal direction of the leak-proof wall sheet 21 to the other end. Therefore, the diaper 1 bends with the skin side face inward due to the contraction force of the elastic member 22 for the leak-proof wall, and the leak-proof wall sheet 21 between the first joint portions 23 stands up the second joint portion 24. Stands on the skin side in the thickness direction as a point.

  As described above, the diaper 1 has a portion in the thickness direction from the top sheet 2 (main body portion 1 ′) to a portion on the outer side in the width direction and on the inner side in the width direction than the pair of leg-hole stretchable portions 10. A pair of leak-proof wall parts 20 which stand on the skin side are provided. The excrement is dammed by the leak-proof wall part 20, and leakage of excrement from the leg opening LH can be suppressed. In the width direction, a section from the inner end in the width direction of the second joint portion 24 to the inner end in the width direction of the leak-proof wall sheet 21 is referred to as a leak-proof wall portion 20.

Examples of the emboss pattern include a pattern in which a plurality of embossed rows in which a plurality of embosses in the form of dots or flowers of about 1 to 3 mm are arranged in the longitudinal direction are arranged in the width direction. The areas to which such an emboss pattern is applied are referred to as first and second mark areas 31 and 32. Further, part of the fibers of the sheet constituting the diaper 1 is removed to form one or a plurality of apertures in the sheet, and the first and second mark regions 31 and 32 are formed by the visible aperture pattern. Also good.

  The third mark region 33 and the fourth mark region 34 (hereinafter also referred to as third and fourth mark regions 33 and 34) are colored regions that are visible from the non-skin side in the thickness direction, and the longitudinal direction of the diaper 1 Is provided at the front side of the center CL1. The third mark region 33 is provided in the vicinity of the front end 10a in the longitudinal direction of the leg-hole stretchable part 10 on one side (for example, the left side) in the width direction, and the fourth mark region 34 is provided on the other side (for example, the width direction). It is provided in the vicinity of the end 10a on the front side in the longitudinal direction of the leg-side stretchable part 10 on the right side. As shown in FIG. 3, the provision of the third and fourth mark regions 33 and 34 in the vicinity of the end 10a of the leg extension / contraction part is an imaginary line extending outward in the width direction from the reference point 10b in the width direction at the end 10a. Of the area surrounded by L1, the virtual line L2 extending outward in the longitudinal direction from the reference point 10b, and the outline L3 of the diaper 1, a third (fourth) area is formed on the reference point 10b side area (shaded area). That is, at least a part of the mark areas 33 and 34 is provided. As shown in FIG. 4, the third and fourth mark areas 33 and 34 of the present embodiment are provided on the line of the seventh mark area 37, and are provided on the front side in the longitudinal direction from the leg-hole stretchable part 10. .

  Further, when the diaper 1 is worn, the third and fourth mark regions 33 and 34 are formed when an end 1d in the width direction of the front waistline portion 1c (hereinafter also referred to as an abdomen flap portion) runs along the wearer's flank. In addition, this is a region where the wearer should touch the finger. That is, this is an area indicating the position of the finger of the hand having the ventral flap portion 1d.

  The fifth mark area 35 and the sixth mark area 36 (hereinafter also referred to as fifth and sixth mark areas 35 and 36) are colored areas that are visible from the non-skin side in the thickness direction. The fifth mark area 35 is provided in the vicinity of the third mark area 33 on one side (for example, the left side) in the width direction, and the sixth mark area 36 is in the vicinity of the fourth mark area 34 on the other side (for example, the right side) in the width direction. Is provided. The fifth and sixth mark areas 35 and 36 of the present embodiment are provided on the inner side in the longitudinal direction of the third and fourth mark areas 33 and 34, adjacent to the third and fourth mark areas 33 and 34, and It is provided so as to overlap with the leg stretchable part 10 in the thickness direction. In addition, the 5th 6th mark area | regions 35 and 36 may be provided at intervals with the 3rd 4th mark area | region 33,34.

  The fifth and sixth mark regions 35 and 36 are regions where the wearer should touch the finger of the hand opposite to the hand holding the fastening tape 7 when the fastening tape 7 is locked. That is, this is an area indicating the position of the finger of the hand that the wearer presses the ventral flap portion 1d. The fifth and sixth mark areas 35 and 36 have a circular shape different from that of the third and fourth mark areas 33 and 34 and are smaller than the third and fourth mark areas 33 and 34. The fifth and sixth mark areas 35 and 36 are areas colored in a different color from the third and fourth mark areas 33 and 34.

  As described above, since the third and fourth mark areas 33 and 34 and the fifth and sixth mark areas 35 and 36 are areas where the wearer should touch the finger, the length in the width direction and the longitudinal direction is 10 mm. It should be about ~ 20 mm. In addition, the third and fourth mark areas 33 and 34 and the fifth and sixth mark areas 33 and 34 and the fifth and sixth mark areas 35 and 36 are formed into an ellipse or a circle, so that The wearer can sensuously recognize that the mark areas 35 and 36 are the positions of the fingers of the handle of the ventral flap portion 1d. Further, the third and fourth mark regions 33 and 34 are formed so that the wearer's hand is inclined inward in the width direction in accordance with the direction of the hand on which the wearer has the ventral flap portion 1d. It is easy for the wearer to recognize that it is the position of the finger. In other words, the direction of the finger of the holding hand can be designated by making the third and fourth mark areas 33 and 34 oval. As a result, the wearer can easily pull the ventral flap portion 1d along the base of the leg.

  However, the present invention is not limited to the above, and the third and fourth mark areas 33 and 34 and the fifth and sixth mark areas 35 and 36 may be, for example, a triangle, a star, an animal illustration, or the like. Further, the third and fourth mark regions 33 and 34 and the fifth and sixth mark regions 35 and 36 are not limited to being formed by coloring, and may be formed by a visually visible emboss pattern.

  The pair of seventh mark areas 37 is an area that serves as a mark for fitting the leg stretchable part 10 along the base of the wearer's leg when worn, and is a colored area that is visible from the non-skin side in the thickness direction. is there. The pair of seventh mark regions 37 are located on both outer sides in the width direction. Each of the pair of seventh mark regions 37 extends from a portion along the leg-hole stretchable portion 10 and from the vicinity of the front end 10a in the longitudinal direction of the leg-hole stretchable portion 10 to the side end 1e in the width direction of the front waistline portion 1c. And a portion that extends from the vicinity of the rear end 10c in the longitudinal direction of the leg stretchable portion 10 to the side end 1f in the width direction of the rear waistline portion 1a.

  In the present embodiment, a portion along the leg-hole stretchable part 10 has a line shape parallel to the longitudinal direction of the leg-hole stretchable part 10 and overlaps with the leg-hole stretchable part 10 in the thickness direction. However, the present invention is not limited thereto, and the portion along the leg-hole stretchable part 10 only needs to extend in the longitudinal direction of the leg-hole stretchable part 10, and is inclined or curved with respect to the longitudinal direction of the leg-hole stretchable part 10. Alternatively, it may not overlap with the leg stretchable part 10 in the thickness direction. Further, the seventh mark region 37 is not limited to extend from the vicinity of the longitudinal ends 10a, 10c of the leg stretchable portion 10 to the side ends 1e, 1f of the diaper 1, but extends toward the end of the diaper 1 in the width direction. It only has to be.

  Moreover, in the diaper 1 of this embodiment, suppose that the size, an illustration, the mark of the fastening position of the fastening tape 7, etc. are printed on the back sheet 3. And each mark of 3rd 4th mark area | region 33,34, 5th 6th mark area | region 35,36, and 7th mark area | region 37 is printed on the back sheet 3, and when it visually recognizes via the exterior sheet | seat 5. FIG. To do. Therefore, the third and fourth mark areas 33 and 34, the fifth and sixth mark areas 35 and 36, and the seventh mark area 37 are colored in a color different from the ground color of the back sheet 3 and the ground color of the exterior sheet 5. Territory. For example, when the background color of the back sheet 3 or the like is white, the third, fourth and third mark areas 33 and 34, the fifth and sixth mark areas 35 and 36, and the seventh mark area 37 are colored blue, red, and green. Good. When printing the marks on the third and fourth mark areas 33 and 34, the fifth and sixth mark areas 35 and 36, and the seventh mark area 37 on the back sheet 3 in this way, In comparison, the number of sheets to be printed is reduced and the diaper 1 can be easily manufactured. Further, the third and fourth mark areas 33, 34, etc. may be printed on the exterior sheet 5, for example, but printing on the back sheet 3 can be printed more clearly and printing peeling can be prevented.

  The eighth mark area 38 and the first and second mark areas 31 and 32 are preferably invisible from the non-skin side, and the third and fourth mark areas 33 and 34 and the fifth and sixth mark areas 35 and 36 are not visible. The seventh mark region 37 is preferably invisible from the skin side. By doing so, each mark area | region 31-38 can be utilized without a wearer being confused, and the complexity of appearance is also eliminated.

Next, a method for attaching the diaper 1 having the first to eighth mark regions 31 to 38 will be described.
FIG. 5 is a view showing a state in which the diaper 1 is laid under the wearer's buttocks. 6 and 7 are diagrams when the diaper 1 is fitted to the wearer's abdomen. FIG. 8 is a view when the end in the width direction of the front waistline portion 1c of the diaper 1 is placed along the wearer's flank. FIG. 9 is a view when the fastening tape 7 is locked. FIG. 10 is a diagram of the state in which the fastening tape 7 is locked.

  First, the wearer (mother, caregiver, etc.) of the diaper 1 lays the diaper 1 under the buttocks of the diaper 1 wearer (baby, elderly person, etc.). At this time, as shown in FIG. 5, the wearer aligns the boundary between the wearer's buttocks and legs with the eighth mark region 38 of the diaper 1.

  By doing so, the rear waistline part 1a, the crotch part 1b, and the front waistline part 1c of the diaper 1 can be appropriately aligned with the wearer. Therefore, a wearer's buttocks and abdomen can be firmly covered with the diaper 1, and leakage from the waistline opening WH can be suppressed. Further, the leg-hole stretchable part 10 can also be appropriately positioned with respect to the base of the wearer's leg, and the leg-hole stretchable part 10 can be easily along the base of the wearer's leg. Therefore, the leg periphery elastic part 10 fits in a wearer's leg root without gap, and can suppress the leak from the leg periphery opening LH. Moreover, even if a wearer moves a leg by fitting the leg periphery elastic part 10 to the base of a wearer's leg, the diaper 1 becomes difficult to slip | deviate.

  Next, the wearer folds the diaper 1 in the longitudinal direction so that the front waistline portion 1c of the diaper 1 fits the wearer's abdomen. At this time, as shown in FIGS. 6 and 7, the wearer brings the first mark area 31 and the second mark area 32 close to each other so that the non-skin side surface 1A of the diaper 1 is convex. Specifically, the first mark area 31 and the second mark area 32 are adjacent to each other, made to face each other, or brought into contact with each other. By doing so, the front part of the diaper 1 in the longitudinal direction is folded in the width direction with the skin side face inside.

  The width of the diaper 1 is wider than the width of the wearer's crotch. Therefore, if the diaper 1 is simply folded in the longitudinal direction, the leg-hole expansion / contraction part 10 comes into contact with a thin portion of the leg below the base of the leg. If it does so, a clearance gap will arise in leg opening LH, and excrement will leak from leg opening LH. Therefore, when the diaper 1 is folded in the longitudinal direction, the width of the diaper 1 is reduced by reducing the width of the diaper 1 by bringing the first mark area 31 and the second mark area 32 close to each other as described above. The width of the crotch part can be adjusted, and the leg-hole stretchable part 10 can be along the base of the wearer's leg. Therefore, the leg periphery elastic part 10 fits in a wearer's leg root without gap, and can suppress the leak from the leg periphery opening LH. Further, since the first mark area 31 and the second mark area 32 can be brought close to each other, the leak preventive wall section 20 can be mounted while standing, so that the excrement hardly leaks through the leak preventive wall section 20. Moreover, a wearer can recognize the leak-proof wall part 20, and can give a wearer a sense of security.

  Next, the wearer places the ventral flap portion 1d on the left side in the width direction along the wearer's flank. At this time, as shown in FIG. 8, the wearer touches the third mark area 33 on the left side in the width direction (specifically, the third mark area 33 in the exterior sheet 5). The ventral flap portion 1d. Further, the wearer causes the seventh mark region 37 to enter the base of the wearer's leg in a circle so that the leg-hole stretchable part 10 follows the base of the wearer's leg. At this time, the wearer aligns the fifth mark area 35 on the left side in the width direction with the upper part of the base of the wearer's leg (the upper part of the V line), and further places the fifth mark area 35 on the wearer's leg. The abdomen flap part 1d is hooked on the wearer's leg while pressing against the base.

  As described above, the third mark region 33 (or the fourth mark region 34) in the vicinity of the end 10a of the leg-hole stretchable part 10 is held by the wearer, so that the entire area of the leg-hole stretchable part 10 is rooted on the wearer's leg. The leg-hole stretchable part 10 can be extended to the vicinity of the wearer's flank. Moreover, since the 7th mark area | region 37 is provided in the diaper 1, the wearer can be conscious of the leg periphery elastic part 10, and it becomes easy to let the leg periphery elastic part 10 follow the root of a wearer's leg. Moreover, the leg periphery expansion-contraction part 10 can be firmly extended by utilizing the 5th mark area | region 35 (or 6th mark area | region 36) for position alignment with a wearer's leg. Further, by using the fifth mark area 35 (or the sixth mark area 36) as a starting point mark for hooking the abdominal flap part 1d on the wearer's leg, the leg-hole expansion / contraction part 10 is firmly attached to the wearer's leg. It can be along the root. Therefore, the leg periphery elastic part 10 fits in a wearer's leg root without gap, and can suppress the leak from the leg periphery opening LH.

  Next, the wearer holds the ventral flap portion 1d on the left side in the width direction with the right hand while holding it with the left hand. At this time, the wearer touches the fifth mark area 35 on the left side in the width direction (for example, touches the fifth mark area 35 in the exterior sheet 5) so that the right hand finger (for example, the index finger or the middle finger) Hold the ventral flap 1d. Thereafter, the wearer holds the fastening tape 7 with the left hand away from the ventral flap portion 1d as shown in FIG. 9, and locks the fastening tape 7 as shown in FIG.

  In this way, when the wearer swaps the left and right hands holding the ventral flap portion 1d for locking the fastening tape 7, the fifth mark in the vicinity of the third mark area 33 (or the fourth mark area 34). By pressing the region 35 (or the sixth mark region 36) with a finger, the leg-hole stretchable part 10 can be kept extended along the base of the wearer's leg, and the fastening tape 7 is locked in that state. it can. Therefore, the diaper 1 is mounted in a state in which the leg-hole stretchable part 10 is fitted to the base of the wearer's leg without a gap.

  Similarly, the fastening tape 7 on the right side in the width direction is also locked. Briefly, the wearer places the left flap on the right side in the sixth mark area 36 on the right side when the abdomen flap portion 1d is placed on the flank while bringing the finger of the right hand into contact with the fourth mark area 34 on the right side in the width direction. While touching the finger, the ventral flap portion 1d is pressed, and the fastening tape 7 is locked with the right hand. Thus, the wearing of the diaper 1 is completed. After the diaper 1 is mounted, it may be confirmed that the seventh mark region 37 is along the base of the wearer's leg, that is, the leg-hole stretchable part 10 is along the base of the wearer's leg. By doing so, leakage from the leg opening LH can be suppressed more reliably.

  In addition, the mounting method of the diaper 1 is not restricted to the above. For example, the right fastening tape 7 may be locked first. Further, for example, the wearer holds the left ventral flap portion 1d along the left side of the wearer while bringing the right finger in contact with the third mark region 33 on the left side in the width direction, and places the fifth mark on the left side in the width direction. The left ventral flap 1d may be pressed while the left finger is in contact with the region 35, and the left fastening tape 7 may be locked with the right hand.

  As described above, by providing the first to eighth mark regions 31 to 38 in the diaper 1, the leg-diameter stretchable part 10 supports the wearer of the diaper 1 so that it fits in the base of the wearer's leg without any gap. This can reduce individual differences in wearing. In other words, the diaper 1 provided with the first to eighth mark regions 38 is appropriately worn so that leakage from the leg opening LH is suppressed no matter who is wearing it.

  In other words, by providing the first to eighth mark regions 38 on the diaper 1, the method for attaching the diaper 1 can be described so that the diaper 1 is appropriately attached. The explanation method of the wearing method of the diaper 1 indicates that the first to eighth mark regions 31 to 38 are respectively located on the diaper 1 and explains the wearing method to the wearer as described above. Specifically, a form in which a wearing method is shown by a photograph, an illustration, or a letter on a package of a diaper 1, a magazine, or the web, or a form in which a video showing the wearing method is placed on a TV CM or a website Is mentioned. By explaining the wearing method in this way, the wearer can appropriately wear the diaper 1.

  Moreover, it is good to make the 1st mark area | region 31 and the 2nd mark area | region 32 into a linear area | region long in the longitudinal direction of the diaper 1 like this embodiment. By doing so, when the diaper 1 is fitted to the wearer's abdomen when the diaper 1 is worn (FIG. 6 and FIG. 7), the longitudinally front portion of the diaper 1 is folded in the width direction over a wide range in the longitudinal direction. Can do. Therefore, the diaper 1 can be fitted to the wearer's abdomen more securely while adjusting the width of the diaper 1 to the width of the wearer's crotch, and the leg-hole stretchable part 10 is made to follow the base of the wearer's leg. Can do.

  Further, in the longitudinal direction, the first mark region 31 and the second mark region 32 may be positioned in a region overlapping the absorber core 41 in the thickness direction. That is, as shown in FIG. 3, the inner ends 31 a and 32 a in the longitudinal direction of the first mark region 31 and the second mark region 32 are longer in the longitudinal direction than the outer end 41 a in the longitudinal direction of the absorbent core 41. It should be located inside. By doing so, the site | part with high rigidity in which the absorber core 41 exists can be approximated, and it becomes easy to fold the diaper 1 in the width direction, and can be folded stably. Therefore, the diaper 1 can be fitted to the wearer's abdomen more securely while adjusting the width of the diaper 1 to the width of the wearer's crotch, and the leg-hole stretchable part 10 is made to follow the base of the wearer's leg. Can do.

  Moreover, it is good to provide the 1st mark area | region 31 and the 2nd mark area | region 32 in the range from the front end of the diaper 1 to the length of 1/3 of the product length of the diaper 1 in a longitudinal direction. This is because if the first and second mark areas 31 and 32 are provided on the rear side in the longitudinal direction from this range, the diaper 1 is worn while bringing the first mark area 31 and the second mark area 32 closer to each other. This is because it is difficult to match the width of the diaper 1 to the width of the wearer's crotch when matching the abdomen of the wearer. In addition, the product length of the diaper 1 is the length of the state in which the diaper 1 is extended. That is, it is the length in a state where the contractive force of the stretchable member provided in the diaper 1 is not expressed.

  In the width direction, the first mark area 31 and the second mark area 32 may be positioned in an area that overlaps the leak-proof wall portion 20 in the thickness direction. That is, at least a part of each of the first mark region 31 and the second mark region 32 is preferably located between the outer end 20a in the width direction and the inner end 20b in the width direction of the leak-proof wall portion 20. By doing so, the distance between the first mark area 31 and the second mark area 32 in the width direction is not too narrow or too wide, and the diaper 1 is matched with the width of the wearer's crotch portion while changing the width of the diaper 1 1 can be fitted to the wearer's abdomen, and the leg-hole stretchable part 10 can be placed along the base of the wearer's leg.

  Moreover, when the wearer brings the first mark area 31 and the second mark area 32 close to each other, when the pair of leak-proof wall parts 20 are brought close to each other, the leak-proof wall part 20 stands up. In particular, the leak-proof wall part 20 stands up more reliably by making the fixing position (1st junction part 23a) of the longitudinal direction of the leak-proof wall part 20 into the 1st 2nd mark area | regions 31 and 32. FIG. Then, the leg-hole stretchable part 10 enters the inner side in the width direction as the leak-proof wall part 20 rises, and the leg-hole stretchable part 10 becomes more easily along the base of the wearer's leg. In addition, since the leak-proof wall portion 20 extends along the base of the wearer's leg and the crotch portion when the leak-proof wall portion 20 stands up, excrement is easily blocked by the leak-proof wall portion 20. Moreover, a wearer can recognize the leak-proof wall part 20, and can give a wearer a sense of security.

  In the width direction, the first mark region 31 and the second mark region 32 may be positioned in a region overlapping the absorber core 41 in the thickness direction. That is, the first mark region is located on the inner side in the width direction from the outermost end 41b in the width direction of the absorber core 41 portion having the same position in the longitudinal direction as the first mark region 31 and the second mark region 32. At least a part of each of 31 and the second mark area 32 may be located. By doing so, the site | part with high rigidity in which the absorber core 41 exists can be approximated, and it becomes easy to fold the diaper 1 in the width direction, and can be folded stably.

  Further, the first mark region 31 and the second mark region 32 are more outward in the width direction than the narrowest portion of the absorber core 41, that is, the innermost end 41c in the width direction of the absorber core 41. Good location. In the case of the present embodiment, the first mark region 31 and the second mark region 32 are positioned on the outer side in the width direction than the notch vertex 41 c provided in the absorber core 41. By doing so, the width | variety of the width direction of the 1st mark area | region 31 and the 2nd mark area | region 32 is not too narrow, and the diaper 1 is used for a wearer's abdomen, adjusting the width | variety of the diaper 1 to the width | variety of a wearer's crotch part. The leg-hole stretchable part 10 can be made to follow the base of the wearer's leg.

  However, the present invention is not limited to the above, and the first mark region 31 and the second mark region 32 do not overlap the absorber core 41 in the longitudinal direction, or do not overlap the leak-proof wall portion 20 and the absorber core 41 in the width direction. May be. In addition, the first mark region 31 and the second mark region 32 may be located on the inner side in the width direction than the portion where the width of the absorber core 41 is the narrowest.

  In the present embodiment, the third mark area 33 and the fourth mark area 34, and the fifth mark area 35 and the sixth mark area 36 have different colors, different sizes, and different shapes. By doing so, the wearer can definitely use the third mark area 33 and the fourth mark area 34 and the fifth mark area 35 and the sixth mark area 36 by distinguishing them. In general, when the wearer holds the ventral flap portion 1d along the wearer's flank, the thumb contacts the outer sheet 5, and when the wearer presses the ventral flap portion 1d, the index finger or middle finger touches the outer sheet 5. To touch. Therefore, in particular, by making the third mark area 33 and the fourth mark area 34 larger than the fifth mark area 35 and the sixth mark area 36, the third mark area 33 and the fourth mark area 34, The wearer can sensuously recognize that the mark area 35 and the sixth mark area 36 are holding positions when the ventral flap portion 1d is changed. However, the present invention is not limited to the above, and the third mark area 33 and the fourth mark area 34 and the fifth mark area 35 and the sixth mark area 36 may be the same color, the same size, or the same shape. May be. Further, the fifth mark area 35 and the sixth mark area 36 may be larger than the third mark area 33 and the fourth mark area 34.

  In the present embodiment, the fifth mark region 35 and the sixth mark region 36 are located in a region overlapping the leg-hole stretchable part 10 in the thickness direction. If the fifth mark region 35 and the sixth mark region 36 do not overlap the leg-hole stretchable part 10, the positional relationship between the leg-hole stretchable part 10 and the base of the wearer's leg may be shifted. Therefore, at least one of the third mark area 33 and the fourth mark area 34, and the fifth mark area 35 and the sixth mark area 36 may be positioned in an area that overlaps the leg stretchable part 10 in the thickness direction. By doing so, it is possible to follow the root of the wearer's leg in a state where the leg-hole stretchable part 10 is firmly stretched, and the stretched state can be maintained. Note that it is only necessary that at least a part of each of the third to sixth mark regions 33 to 36 overlaps with the leg stretchable part 10 in the thickness direction.

  Further, the seventh mark region 37 of the present embodiment includes an end portion in the width direction of the front waistline portion 1c from the vicinity of the front end 10a in the longitudinal direction of the leg periphery stretchable portion 10 in addition to the portion along the leg stretchable portion 10. It has a part which goes to. Therefore, after the diaper 1 is mounted, it is confirmed that the portion of the seventh mark region 37 extending from the vicinity of the end 10a of the leg-hole stretchable part 10 intersects with the rear end of the leg-hole stretchable part 10 in the longitudinal direction. It can be confirmed that the leg opening LH is not too large. Therefore, the leakage from the leg opening LH can be further suppressed. However, the present invention is not limited to this, and the seventh mark region 37 may have only a portion along the leg-hole stretchable part 10.

  In addition, when the diaper 1 is worn, the non-skin side surface of the diaper 1 is only visible on the front side in the longitudinal direction. Therefore, the 7th mark area | region 37 should just extend to the front side of a longitudinal direction from the center CL1 of the longitudinal direction of the diaper 1, or the center of the longitudinal direction of the leg periphery expansion-contraction part 10, and does not extend to the back side of a longitudinal direction. Also good. However, since the seventh mark region 37 is also provided on the rear side in the longitudinal direction of the diaper 1, it is easy to perform the above confirmation whether the leg opening LH is too large.

=== Modification ===
11A and 11B are explanatory diagrams of modified examples of the first mark area 31 and the second mark area 32. The first joint portion 23 between the leak-proof wall sheet 21 and the top sheet 2 is not limited to the first and second mark regions 31 and 32 as in the above embodiment. For example, as shown in FIG. 11A, the first second mark areas 31 and 32 are extended longer in the longitudinal direction than the first joint portion 23, and the length of the first second mark areas 31 and 32 is extended. The length of the diaper 1 may be about 1/3 of the product length. By doing so, when the diaper 1 is fitted to the wearer's abdomen, the longitudinally front portion of the diaper 1 can be folded in the width direction over a wide range of the longitudinal direction, and the leg-hole stretchable part 10 can be more reliably secured. Along the base of the wearer's leg.

  Further, the first and second mark regions 31 and 32 are not limited to line-like regions that are long in the longitudinal direction of the diaper 1. Further, the first mark area 31 and the second mark area 32 may have different shapes. For example, as shown in FIG. 11B, the first mark region 31 may have a ring shape, and the second mark region 32 may have a circular shape having the same size as the hollow portion of the first mark region 31. By doing so, the wearer can sensuously recognize that the second mark area 32 is aligned with the hollow portion of the first mark area 31, that is, the first mark area 31 and the second mark area 32 are brought close to each other. .

  12A to 12C are explanatory diagrams of modified examples of the seventh mark region 37. FIG. The seventh mark area 37 is not limited to a solid line as in the above embodiment, but may be a dotted line, for example.
