<First Embodiment>
Referring to FIGS. 1 to 5, a disposable diaper 10 that is an example of a disposable wearing article according to the first embodiment of the present invention has a vertical axis Y and a horizontal axis X orthogonal thereto, and is opposed to the skin facing surface. It includes a non-skin facing surface, a front waist region 11, a rear waist region 12, and a crotch region 13 located between the front waist region 11 and the rear waist region 12. In each figure in which the diaper 10 is developed, each elastic body to be described later is in an extended state against the contraction force.

  For convenience of explanation, the crotch region 13 is divided into a first region 21 extending from the horizontal axis X toward the front waist region 11 and a second region 22 extending from the horizontal axis X toward the rear waist region 12.

  The diaper 10 has front and rear end portions 23 and 24 extending in parallel with the horizontal axis X, and both side edge portions 25 and 26 that are symmetrical with respect to the vertical axis Y and are opposed to each other in the direction of the horizontal axis X. The side edges 25 and 26 are formed in a concave shape in the crotch region so as to fit along the wearer's thighs, and the portion of the crotch region 13 on the front waist region 11 side at the center is the most. It is narrow. The front side edges 11a, 11b of the front waist region 11 and the rear side edges 12a, 12b of the rear waist region 12 are intermittent in the direction of the vertical axis Y between the side edges facing each other in the front-rear direction of the diaper 10. A waist opening 30 and a pair of leg openings 31 are defined by being connected by side seams 28 that extend to each other. The side seam 28 is formed by fusing sheets overlapping each other by embossing / debossing with heat or ultrasonic waves.

  The diaper 10 is located on the non-skin facing surface, and extends to the front and rear waist regions 11 and 12 and the crotch region 13 in series. The diaper 10 is located on the skin facing surface, has the same shape as the outer layer sheet 32, and has an opening at the center. And an inner layer sheet 33 on which 33a is formed. Between the outer layer sheet 32 and the inner layer sheet 33, a plurality extending in the direction of the horizontal axis X along the front and rear end portions 23 and 24 between the front and rear side edge portions 11a, 11b, 12a and 12b of the front and rear waist regions 11 and 12. The first waist elastic region 34 of the strip, and the first and second regions 21 of the front and rear side edges 11a, 11b, 12a, 12b and the crotch region 13 inward in the direction of the longitudinal axis Y of the first waist elastic region 34. , 22 and a plurality of second waist elastic bodies 35 extending in the direction of the horizontal axis X are disposed so as to be contractible in an extended state.

The inner and outer layer sheets 32 and 33 are, for example, liquid-impermeable and preferably breathable, having a mass of about 10 to 40 g / m ² and a fiber density of about 0.03 to 0.1 g / cm ³ . A spunbond fiber nonwoven fabric, an SMS (spunbond / meltblown / spunbond) fiber nonwoven fabric, an air-through fiber nonwoven fabric, a porous plastic film, or a laminate sheet thereof can be used. The outer layer sheet 32 has a total light transmittance such that first and second decorative portions 41A, 41B and indicator means 43 described later can be visually recognized from the outer surface.

  The first and second waist elastic bodies 34 and 35 are formed of, for example, a string-like or strand-like elastic material having a fineness of about 470 to 1240 dtex, and have a length of about 1.5 to 3.3 in a contracted or relaxed state. It can arrange | position in the state extended | stretched 5 times. Conditions such as the thickness of the first and second waist elastic bodies 34 and 35, the expansion ratio, and the separation dimension (pitch) between the elastic bodies can be appropriately changed, but can be stably applied to the wearer's body. In order to be worn, it is preferable to set the conditions of each elastic body so that the contraction force of the elastic region by the first waist elastic region 34 is larger than that of the elastic region by the second waist elastic body 35. Further, as the first and second waist elastic bodies 34 and 35, an elastic sheet having a required width fixed to the inner and outer layer sheets 32 and 33 can be used in addition to the string-like or strand-like elastic material.

  Between the outer layer sheet 32 and the second waist elastic body 35, a rectangular leak-proof sheet (illustration sheet) 42 having a plurality of appropriate display elements 40 printed on the outer surface thereof is disposed. The display element 40 is formed of a coloring material such as ink that does not change visually even when it touches moisture such as liquid of excrement. The display element 40 is disposed in the front waist region 11 and 12 and the second region 22 of the crotch region 13 and is composed of a plurality of display elements 40 that are visible from the outside. The first decorative portion 41A and the second decorative portion 41B located in the rear waist region 12 and the second region 22 are formed.

  In the present embodiment, a star pattern is shown as an example of the display element 40, but various known figures, decorative patterns, patterns, product trademarks, manufacturer's marks, and the like may be used. In particular, when a design having a design such as a character is attached as the display element 40, a design effect is exhibited and the appearance of the diaper 10 is improved. The leak-proof sheet 42 may be formed by combining a plurality of sheet members. The leak-proof sheet 42 is formed from a liquid-impervious fiber nonwoven fabric, a liquid-impervious and breathable plastic film, or a laminate sheet thereof, and has an outer dimension that covers at least the entire lower surface of the absorbent structure, and absorbs the leakage. The excrement is prevented from leaking from the bottom of the structure.

  An indicator means 43 for notifying the mother or the wearer of the presence or absence of excretion is provided at a portion of the inner surface of the leak-proof sheet 42 located in the first area 21 of the crotch area 13. The indicator means 43 has a plurality of lines that are spaced apart from each other in the direction of the vertical axis Y and extend in the direction of the horizontal axis X. When the indicator means 43 gets wet with excrement liquid such as urine, the indicator means 43 is visually recognized from the outside. It is formed from a possible ink layer 44 and, optionally, a cover sheet 45 containing preferably the required amount of surfactant. For the ink layer forming the indicator means 43, a known material used in this type of field, for example, a coloring material such as an ink containing a YH indicator, can be used, preferably the first and second decorative portions 41A, Various known figures, decorative patterns, pictures, characters, and the like different from the display element 40 with 41B may be used. In this embodiment, the indicator means 43 is comprised from the indicator element which consists of a plurality of lines, The inner side part 43a represents the element located in the innermost side among indicator elements, and the outer side part 43b is located in the outermost side. However, it may have an outer shape in which they are integrated.

  Referring to FIG. 3, the diaper 10 is configured by interposing a plurality of constituent members between the inner layer sheet 33 and the outer layer sheet 32, and in order from the skin facing surface side, the inner layer sheet 33, a pair of barrier sheets 46, A body-side liner 47 made of a fiber nonwoven fabric having liquid permeability, a pad-like absorbent structure 48 having absorption properties, first and second waist elastic bodies 34 and 35, a leak-proof sheet 42, and an outer layer sheet 32 are laminated. Yes.

  The absorbent structure 48 includes a liquid absorbent core material 49 formed from a mixture of wood fluff pulp and superabsorbent polymer particles, and a liquid diffusible core wrap such as tissue paper covering the entire core material. Sheet 50. The pair of barrier sheets 46 are spaced apart from each other in the direction of the horizontal axis Y, and are connected to both sides of the body side liner 47 via hot melt adhesive, and the front and back sides of the body side liner. It is formed by bending and fixing the side part of the barrier sheet 46 that extends in the direction of the longitudinal axis Y between the front and rear fixed end parts fixed to the end part via a hot melt adhesive. And a sleeve-like or loop-like distal edge 51. An elastic body 52 is attached to the inside of the distal edge 51 so as to be contracted in an extended state. When the diaper 10 is worn, the elastic body 52 contracts to move the distal edge 51 away from the body-side liner 47 toward the wearer's body, and fits the wearer's thigh to prevent excrement from leaking. A leakage prevention wall is formed.

  Referring to FIG. 2, the body side liner 47 and the distal edge 51 of the barrier sheet 46 are covered with the inner layer sheet 33, and the central part thereof is exposed to the outside through the opening 33a. The body fluid excreted in the portion of the absorption structure 48 exposed from the opening 33a is absorbed and held by the absorption structure, and the portion of the barrier sheet 46 covered by the inner layer sheet 33 is hot on the inner surface of the inner layer sheet 33. Only the distal edge 51 of the barrier sheet 46 that is fixed through the melt adhesive and exposed from the opening 33a functions as a leak-proof wall.

  Referring to FIGS. 4 and 5, the indicator means 43 is positioned so as to overlap a part of the second waist elastic body 35 disposed in the first area 21 of the crotch area 13. In the wearing state of the diaper 10, the second waist elastic body 35 is not disposed, and the central portion of the first area 21 where the absorption structure 48 positioned inwardly is located on the second waist elastic body 35. Without being tightened, the shape of the pad-like absorbent structure 48 having compression / restoration elasticity is maintained, so that the pad swells outward. As shown in the enlarged view of FIG. 5, the bulging portion 60 is curved starting from the vicinity of the inner portion 35 a of the second waist elastic body 35, so that when the wearer looks down, the (upper) proximal end The vicinity of 60a can be easily visually recognized. Since the outer portion 43b of the indicator means 43 is positioned so as to overlap the inner portion 35a of the second waist elastic body 35, the outer portion 43b extends from the vicinity of the base end 60a to a portion that curves, and the wearer can easily access the inner portion 43a. Can be visually recognized.

  Further, in the first area 21 of the front waist region 11 and the crotch region 13, the first decorative portion 41 </ b> A having a design effect is located apart from the indicator means 43 by a given dimension, and the horizontal axis of the indicator means 43 They are not arranged on both sides in the X direction. Thus, by arranging the first decorative portion 41A in the front waist region 11, the design effect of the entire diaper 10 is improved, while the first decorative portion 41A is arranged directly above and on both sides of the indicator means 43. Therefore, there is no possibility that the line of sight is guided when confirming urination and the first decorative portion 41A is mistakenly mistaken for the indicator means 43. In particular, the first decorative portion 41A is arranged around the indicator means 43 when the wearer himself confirms urination by looking down with the opening of the waist of clothing such as underwear and pants expanded forward. If it is, it is difficult to discriminate between the first decorative portion 41A and the indicator means 43, but there is no possibility of causing such a disadvantage. In addition, when the wearer is an infant undergoing toilet training, even if the mother etc. verbally explained the components such as the shape and color for identifying the indicator means, the indicator means should be placed ahead of the line of sight. In addition, since the decorative portions are arranged, it is difficult to distinguish them instantaneously, and the line of sight is easily guided unintentionally to the decorative portions where the decorative elements such as characters are arranged. In such a case, by not arranging the first decorative portion 41A around the indicator means 43 in this way, the mother or the like indicates the arrangement position together with the components of the indicator means 43 to the wearer, so that the indicator means 43 Can be distinguished.

  In order to easily confirm the indicator means 43 when the wearer looks down himself / herself, the dimension L1 in the direction of the vertical axis Y from the front end edge (waist opening edge) of the diaper 10 to the outer side portion 43b of the indicator means 43 Is preferably about 100 to 150 mm. Moreover, it is preferable that the indicator means 43 is located in the front waist region 11 side rather than the center part of the separation dimension R1 of the horizontal axis X and the inner side part 35a of the 2nd waist elastic body 35 in the direction of the vertical axis | shaft Y. . Since the vicinity of the horizontal axis X is sandwiched between the thighs of the wearer and the region where the second waist elastic body 35 is disposed is fitted to the wearer's body by the contraction force, the horizontal axis X and As shown in FIG. 5, the portion between the inner portion 35 a and the inner portion 35 a protrudes outward, and as shown in FIG. Projecting part) 62b. The indicator means in the normal diaper is located behind the most projecting part 62b so that it is difficult for the wearer to visually recognize the indicator means 43. In this embodiment, the indicator means 43 is located on the front waist than the most projecting part 62b. Since it is located in area 11, it can be visually recognized instantaneously when the wearer looks down. In order to achieve such an effect, the indicator means 43 is preferably located at least between the horizontal axis X and the inner portion 35a. However, by arranging the indicator means 43 only in the region and not in other regions, the indicator means 43 can be efficiently disposed. The wearer himself can be informed of urination, and the appearance of the indicator means 43 can be prevented from being deteriorated by arranging the indicator means 43 in a relatively wide range, and the material cost can be reduced.

  In order to easily distinguish the indicator means 43 from the first decorative portion 41A, the distance between the inner end edge 64 of the first decorative portion 41A and the outer portion 43b of the indicator means 43 in the direction of the vertical axis Y is determined. R2 is preferably about 5.0 mm or more. This is because when the separation dimension R2 is about 5.0 mm or less, the first decorative portion 41A and the indicator means 43 are close to each other, and the wearer and the wear assistant may not be able to easily distinguish them. .

  The separation dimension R3 in the direction of the vertical axis Y between the inner portion 43a of the indicator means 43 and the inner portion 66 of the second decorative portion 41B is preferably about 5.0 mm or more. In such a case, the outer portion 43b of the indicator means 43 and the second decorative portion 41B are not close to each other, and there is no possibility that the wearer or the like is deprived of his / her line of sight. Further, the dimension in the direction of the horizontal axis X of the first and second decorative portions 41A, 41B is larger than the dimension of the indicator means 43 in the horizontal axis X. Specifically, the former is about 180 mm and the latter is about 60 mm. Thus, the first and second decorative portions 41A, 41B are larger in the horizontal axis X direction than the indicator means 43 in the horizontal axis X direction. Since the non-decoration part in which the display element 40 is not disposed surrounded by the second decoration parts 41A and 41B is formed, the indicator means 43 can be made relatively conspicuous.

  The color of the indicator means 43 before contact with urine and the color of the indicator means 43 that has been colored or changed after contact with urine are preferably dissimilar to the colors of the first and second decorative portions 41A and 41B. If these colors are similar, when the wearer confirms urination, the first and second decorative portions 41A, 41B cannot be distinguished from the indicator means 43, and there is a risk of misidentifying the presence or absence of urination. Because there is. Here, the color dissimilarity is such that an observer (wearer or wear assistant) having normal attention can recognize that they are not similar, for example, an Oswald ( Ostwald) This is a case where the color charts of the 24 color formulas classified in the hue circle are different colors and are opposite colors. Thus, when the color before the urination of the indicator means 43 and the color changed or changed after the urination are opposite colors of the first and second decorative portions 41A, 41B, the indicator means 43 The contrast between the first and second decorative portions 41A and 41B becomes clear, making it easier to distinguish them.

<Example of change>
FIG. 6 shows an example of a modification of the shape of the indicator means 43. The indicator means 43 is a plurality of lines extending in the direction of the horizontal axis X and spaced apart from each other in the direction of the vertical axis Y by a given dimension. And the dimension in the direction of the horizontal axis X gradually increases from the outer side portion 43b toward the inner side portion 43a. In the wearing state of the diaper 10, the lower part of the bulging part 60 located on the inner side (downward) of the inner part 35a of the second waist elastic body 35 is less visible than the part on the outer part 43b side. However, since the indicator means 43 has such an aspect, it is easy to visually recognize the inner side 43a side, and due to its design effect, the line of sight of the wearer and the wear assistant is easily guided to the indicator means 43 unconsciously. Become.

Second Embodiment
Referring to FIG. 7, in the diaper 10 according to the present embodiment, the second waist elastic body 35 extends to both side edges of the leak-proof sheet 42 and is substantially disposed at least in the region where the absorbent structure 48 exists. In addition, in the region where the second waist elastic body 35 is disposed, elastic regions 68A and 68B that are positioned to be spaced apart from each other in the direction of the horizontal axis X and an inelastic region 69 are defined between them. . The inelastic region 69 can be defined by snapping back the second waist elastic body 35 by not cutting the center portion to the sheet member and cutting it in the extended state. In the present embodiment, the outer portion 43b of the indicator means 43 is located side by side with the inner portion 35a of the second waist elastic body 35 in the direction of the horizontal axis X. Even in such a case, the indicator means 43 has the bulging portion 60. Since it is located in the vicinity of the base end 60a, the effects described above can be obtained. Therefore, in this way, the inelastic region 69 is defined, the indicator means 43 is not actually overlapped with the second waist elastic body 35, and at least the outer portion 43b is located in the inelastic region 69. It is not excluded in the present invention. In addition, since the second waist elastic body 35 is not disposed in the region where the liquid absorption structure 48 exists in this manner, wrinkles are formed in the liquid absorption structure 48 due to the contraction force of the second waist elastic body 35. And the liquid absorption performance is not hindered.

<Third Embodiment>
Referring to FIGS. 8 and 9, the diaper 10 according to this embodiment includes a hot melt adhesive applied between at least one of the sheets 32 and 33 between the inner layer sheet 33 and the outer layer sheet 32. And a crotch elastic body 70 fixed so as to be contractible in an extended state. The crotch elastic body 70 has a shape extending in a convex shape from the vicinity of the inner ends of the side edge portions 11a and 11b of the front waist region 11 toward the horizontal axis X, and along the leg opening edge portion of the first area 21. Both side portions 71 extend, and a central portion 72 that crosses the crotch region 13 in the second region 22. The indicator means 43 is located outside the central portion 72 of the crotch elastic body 70 in the direction of the vertical axis Y. By disposing the crotch elastic body 70, the front waist region 11 side of the crotch region 13 fits more on the wearer's body, and side leakage of excrement can be reliably prevented.

  Thus, in the first area 21 of the crotch region 13, the crotch elastic body 70 is disposed so as to surround the indicator means 43, so that the central portion of the bulging portion 60 where the indicator means 43 is disposed is crotch. Since the outer periphery of the elastic body 70 is tightened, the indicator means 43 can be more easily confirmed when it bends outward and the wearer looks down.

<Fourth embodiment>
Referring to FIG. 10, the diaper 10 according to the present embodiment is stretched between the outer layer sheet 32 and the inner layer sheet 33 via a hot melt adhesive applied to at least one of the sheets 32 and 33. And front and rear crotch elastic bodies 74 and 75 fixed to be contractible. The front crotch elastic body 74 has a shape extending in a convex shape from the vicinity of the inner ends of the side edges 11a and 11b of the front waist region 11 toward the horizontal axis X, and extends along the leg opening edge of the first section 21. And both sides 76 extending in the middle and a central part 77 crossing the crotch region 13 in the second region 22. The rear crotch elastic body 75 has a shape extending in a convex shape from the vicinity of the inner ends of the side edges 12a and 12b of the rear waist region 12 toward the horizontal axis X, and extends along the leg opening edge of the second section 22. And both sides 78 extending in the middle and a central part 79 crossing the crotch region 13 in the second zone 22. The central portion 77 of the front crotch elastic body 74 and the central portion 79 of the rear crotch elastic body 75 intersect each other in the vicinity of the horizontal axis X of the first section 21.

  The indicator means 43 is located outward in the direction of the vertical axis Y from the central portion of the rear crotch elastic body 75 and is surrounded by both side portions 76 of the front crotch elastic body 74 and the central portion 79 of the rear crotch elastic body 75. Located in the area. The region is not provided with the second waist elastic body 35 and is surrounded by both side portions 76 of the front crotch elastic body 74 and the center portion 79 of the rear crotch elastic body 75, and the outer periphery thereof is tightened by them. Therefore, the bulging portion 60 has a curved shape that bulges outward as compared with the case where the front and rear crotch elastic bodies 74 and 75 are not provided. Further, the central portion 77 of the front crotch elastic body 74 and the central portion 79 of the rear crotch elastic body 75 intersect each other in the vicinity of the horizontal axis X of the first section 21, so that the lower end of the bulging portion 60 is only the front crotch elastic body 74. It is tightened more strongly than the case where is provided, and the inner end 43a of the indicator means 43 becomes easier to visually recognize when the lower end is bent outward and the wearer looks down.
