Fig. 1 through Fig. 6 show an embodiment of the present invention, and a disposable disposable diaper is exemplified as a wearing article.

Fig. 1 is a perspective view showing a state in which the waist opening and the leg opening of the disposable diaper 10 are kept in a ring shape, and Fig. 2 is a developed plan view seen from the body side of the disposable diaper 10 to resist the elastic bodies of the disposable diaper. The contraction force is extended, and the paper diaper 10 is kept in a flat state. Fig. 3 is a sectional view taken along line III-III of Fig. 2, and Fig. 4 is a sectional view taken along line IV-IV of Fig. 2, and Fig. 5 is a view Fig. 6 is an exploded plan view of the second embodiment, and Fig. 6 is a plan view of the diaper 10 in a state in which the waist opening and the leg opening are unwrapped and closed. In the third and fourth figures, the elastic bodies are in a contracted state on the right side of the figure closer to the virtual longitudinal center line P-P.

The disposable diaper 10 includes a longitudinal direction Y and a lateral direction X, a garment side opposite to the body side, a front waist region 11, a rear waist region 12, and a crotch region 13 between the front and rear waist regions 11, 12. . The disposable diaper 10 further includes: a virtual longitudinal center line PP having two equal lengths in the lateral direction X, and a virtual horizontal center line QQ halving the length dimension of the longitudinal direction Y to face the virtual longitudinal center line PP, It is approximately symmetrical.

The disposable diaper 10 includes a front waist member 20 that forms the front waist region 11, a rear waist member 30 that forms the rear waist region 12, and an underarm that extends toward the front and rear waist regions 11, 12 while forming the underarm region 13. Member 40. The main system of the present invention consists of front and rear waist members 20, 30 and a portion of the underarm member 40.

The front waist member 20 includes a front inner sheet 21 positioned on the body side, a front outer sheet 22 positioned on the garment side, and a front elastic member 23 disposed between the sheets 21, 22. The rear waist member 30 includes a rear inner sheet 31 positioned on the body side, a rear outer sheet 32 positioned on the garment side, and a rear elastic member 33 disposed between the sheets 31, 32. The front and rear elastic members 23, 33 extend in the lateral direction X and are retractably attached in an extended state to elasticize the front and rear waist regions 11, 12 in the lateral direction X. The front and rear elastic members 23, 33 are attached to a predetermined size in the longitudinal direction Y.

The length dimension of the longitudinal direction Y of the rear waist member 30 is larger than that of the front waist member 20, and the side of the crotch region 13 in the longitudinal direction Y of the rear waist member 30, that is, the virtual lateral center line QQ side, forms the front waist member. The lower end region 30a of the underarm region 13 side of 20 extends. In the lower end region 30a, the separated size of the rear elastic member 33 is larger than that of other regions. Thus, by making the separation size larger, it is not necessary to increase the rigidity of the rear inner and outer sheets 31, 32, and the soft touch can be maintained. Further, by the rear elastic member 33 attached to the lower end region 30a, the lower end region 30a can be pressed against the wearer's skin, which prevents accidental bending.

The front and rear waist members 20, 30, as described above, have their side edges 24, 24 joined to each other to form an annular waist opening.

As shown in Fig. 2, the front and rear waist members 20, 30 have their outer end edges 26, 36 located outside the longitudinal direction Y, and are folded back toward the virtual transverse center line QQ to form a front and rear sleeve portion. 25,35. The front and rear sleeve portions 25, 35 cover the ends of the underarm member 40. The crotch member 40 is joined to the front and rear inner sheets 21, 31 at the front and rear waist regions 11, 12, the garment side thereof.

The underarm member 40 includes an inner surface of the liquid-absorbent structure 41, the inner surface of the liquid-absorbent structure 41, an inner sheet 42 on the body side, a leakage preventing sheet 43 covering the outer surface of the liquid-absorbent structure 41, and The outer sheet 44 on the dressing side is the outer surface of the leakage preventing sheet 43. The liquid-absorbent structure 41 includes a liquid-absorbent core material coated with a liquid-diffusing sheet such as absorbent paper, and a liquid-absorbent core material: fluff pulp or superabsorbent polymer particles. The length dimension of the liquid-absorbent structure 41 in the lateral direction X becomes smaller toward the virtual transverse center line Q-Q, and the whole is sand-leaked. That is, the liquid-absorbent structure 41 includes the front and rear portions 45, 46 positioned on the outer side in the longitudinal direction Y, and the intermediate portion 47 located between the front and rear portions 45, 46, and the length dimension of the intermediate portion 47 in the lateral direction X. It is set to be smaller than the front and rear portions 45, 46.

The length dimension of the liquid absorbing structure 41 in the longitudinal direction Y is set to be about 300 to 400 mm, preferably about 335 to 380 mm. The inner sheet 42 and the leakage preventing sheet 43 are larger than the longitudinal dimension of the liquid absorbing structure 41 in the longitudinal direction Y, and the size is preferably set to 350 to 450 mm, preferably about 375 to 430 mm. In the longitudinal direction Y of the crotch member 40, the liquid-absorbent structure 41 is not present, that is, the front and rear wing portions 48, 49 existing only in the inner sheet 42 and the leakage preventing sheet 43 are formed. In the front and rear wing portions 48, 49, the inner sheet 42 and the leakage preventing sheet 43 are joined to each other by a bonding means such as a hot melt adhesive.

As the inner sheet 42, a liquid permeable fibrous nonwoven fabric or the like can be used. As the interior sheet 42, for example, an air-flow type fiber nonwoven fabric, a point-bonded fiber nonwoven fabric, a spunbonded fiber nonwoven fabric, or the like having a mass per unit area of about 10 to 25 g/m ² can be used.

As the leakage preventing sheet 43, a moisture-permeable and liquid-impermeable plastic film can be used, and at least the sheet 43 covers the entire liquid-absorbent structure 41 to prevent leakage of body fluid such as urine from the outside of the disposable diaper 10.

As the exterior sheet 44, a moisture-impermeable, liquid-impermeable fibrous nonwoven fabric or the like can be used. The exterior sheet 44 can be used, for example, a spunbond/melt blown/spunbond (SMS) fiber nonwoven fabric having a mass per unit area of about 10 to 25 g/m ² , a point-bonded fiber nonwoven fabric, and a spunbond type. Fiber is not woven, etc.

The pad hem 50 and the leak hem 60 are formed by the outer sheet 44. The outer sheet 44 of the liner hem 50 extending from the outer surface of the liquid-absorbent structure 41 is formed by the first and second sleeves 51, 61, respectively, and the first and second sleeves 51, 61 are attached thereto. The lateral direction X of the liquid-absorbent structure 41 is folded. (Refer to Figures 2 to 5)

The pad pleats 50 are formed with an inner edge 52 positioned inside the lateral direction X of the first sleeve 51 and an outer edge 53 on the opposite side. The pad elastic member 55 extending in the longitudinal direction Y is attached to the inner surface of the first sleeve 51 in a contracted state, and the pad hem 50 is elasticized in the longitudinal direction Y. The side edge portion of the leakage preventing sheet 43 extending outward from the outer surface of the liquid absorbing structure 41 toward the lateral direction X is positioned between the inner surface of the first sleeve 51, that is, between the exterior sheets 44. On the inner surface of the first sleeve 51, the outer sheet 44, the leakage preventing sheet 43, and the spacer elastic member 55 are joined to each other by a bonding means such as an adhesive to form a spacer bonding region 56. The pad engagement region 56 extends continuously toward the longitudinal direction Y of the underarm member 40.

The pad elastic member 55 includes first to third pad elastic members 55a to 55c that are separated from each other in the lateral direction X. The first pad elastic member 55a extends along the outer edge 53, the third pad elastic member 55c extends along the inner edge 52, and the second pad elastic member 55b extends along the elastic members 55a, 55c. By using the elastic member as described above, the pad pleats 50 can be elasticized in the longitudinal direction Y, and the pad pleats 50 are based on the inner edge 52, so that the outer edge 53 is erected so as to be closely attached to the wearer's thigh root. nearby. Therefore, leakage of urine or the like from the wearer's leg can be prevented.

The pad elastic member 55 is attached so as to overlap with the rear elastic member 33 attached to the lower end region 30a of the rear waist member 30. Therefore, the lower end region 30a can also be elasticized in the longitudinal direction Y, and the lower end region 30a can be closely attached along the curve of the wearer's buttocks. In particular, as in the present embodiment, in the disposable diaper members 20, 30 and the crotch member 40, which are formed of different members, the crotch member 40 is easier than the front and rear waist members 20, 30. Moving, the underarm area 13 is easy to move. However, the movement can be controlled by making the lower end region 30a adhere to the wearer.

For each of the first to third pad elastic members 55a to 55c, an elastic yarn of about 470 to 1240 dtex can be used, and the elongation is set to be about 1.5 to 3.0 times. The first to third pad elastic members 55a to 55c are attached in the lateral direction X so as to be separated from each other by about 3 to 20 mm. By setting the separation distance to 3 mm or more, it is possible to prevent the elastic members from overlapping each other and to contact the wearer's skin, thereby preventing the marks from being creased on the skin. Further, by setting the separation distance to 20 mm or less, the pad hem 50 is surely erected to abut the wearer's skin.

The first to third pad elastic members 55a to 55c are provided outside the lateral direction X at positions corresponding to the intermediate portion 47 of the liquid-absorbent structure 41, and are located at positions corresponding to the front and rear portions 45, 46. Not installed, or only slightly extended. In other words, the first to third pad elastic members 55a to 55c are substantially attached to the front and rear portions 45 and 46 so that the contraction force does not act on the liquid-absorbent structure 41. Therefore, the first to third pad elastic members 55a to 55c can prevent wrinkles from occurring in the front and rear portions 45 and 46.

The third pad elastic member 55c is separated from the side edge of the intermediate portion 47 of the liquid-absorbent structure 41 by about 5 to 15 mm toward the outside. By setting the exit size to 5 mm or more, in addition to preventing wrinkles from occurring in the intermediate portion 47, the rigidity of the intermediate portion 47 can be utilized so as not to impede the necessary contraction of the third spacer elastic member 55c. By setting the separation distance of the third pad elastic member 55c to 15 mm or less, the side edge of the liquid-absorbent structure 41 can be pressed against the body side of the wearer by the necessary contraction of the elastic member.

The leakage hem 60 is formed by a second sleeve 61 folded from the outer sheet 44 extending further from the inner edge 52 of the pleat 50. The outer sheet 44 is joined to the inner surface of the second sleeve 61 and includes a proximal edge 62 that is continuous toward the inner edge 52 and a distal edge 63 that is further on the body side than the proximal edge 62. The inner edge 52 and the proximal edge 62 are substantially the same part. Therefore, the proximal edge 62 and the inner edge 52 are joined to the exterior sheet 44 via the leakage preventing sheet 43 in the entire longitudinal direction Y.

The barrier elastic member 64 extending in the longitudinal direction Y is retractably attached to the second sleeve 61 in an extended state, and the leak preventing hem 60 is elasticized in the longitudinal direction Y. The barrier elastic member 64 includes four elastic members of the first to fourth barrier elastic members 64a to 64d from the distal edge 63 toward the proximal edge 62.

As the first to fourth barrier elastic members 64a to 64d, an elastic yarn of about 470 to 1240 dtex can be used, and the elongation can be set to about 1.5 to 3.0 times. The first to fourth barrier elastic members 64a to 64d are attached in the lateral direction X so as to be separated from each other by about 3 to 20 mm. By setting the separation distance to 3 mm or more, it is possible to prevent the elastic members from overlapping and coming into contact with the wearer's skin, thereby preventing the wrinkles from remaining on the skin. Further, by setting the separation distance to 20 mm or less, the leakage hem 60 is surely erected and abuts against the wearer's skin.

The fourth barrier elastic member 64d is separated from the inner edge 52 of the pad hem 50 toward the distal edge 63 side by about 5 mm or more. By setting the separation distance to 5 mm or more, the inner edge 52 and the proximal edge 62 can be adhered to the wearer's thigh root.

The first to fourth barrier elastic members 64a to 64d are located outside the lateral direction X of the intermediate portion 47 of the liquid-absorbent structure 41, and extend toward the front and rear portions 45, 46.

Between the proximal edge 62 and the distal edge 63 of the leak preventing hem 60, that is, between the third barrier elastic member 64c and the fourth barrier elastic member 64d, a virtual shape extending in the longitudinal direction Y is formed. Bend line 65. The leakage hem 60 is folded along the virtual bending line 65 in a state where the barrier elastic member 64 is not contracted, so that the distal edge 63 is positioned outward of the lateral direction X from the virtual bending line 65. The folded leak preventing hem 60 overlaps the front and rear portions 45, 46 of the liquid-absorbent structure 41 on the body side thereof, and does not overlap in the intermediate portion 47, and is positioned outside the lateral direction X thereof.

The bent leak preventing hem 60 is joined to the inner sheet 42 by the joining means such as an adhesive in the front and rear portions 45, 46 of the liquid absorbing structure 41 to form the front and rear joint regions 66, 67. The front and rear joint regions 66, 67 extend in the longitudinal direction Y.

In the disposable diaper as described above, the distal edge 63 of the leakage hem 60 is erected apart from the inner sheet 42 and is attached to the outer side of the wearer's leg, while the outer side of the pleat 50 is provided. The rim 53 is external to the lateral direction X of the distal edge 63 and is closely attached to the periphery of the wearer's thigh. That is to say, by using these leakage hem 60 and the pad hem 50, a two-layer hem is formed to prevent leakage of urine or the like from the leg circumference.

The elongation stress in the longitudinal direction Y of the above-mentioned leakage hem 60 is greater than the elongation stress in the longitudinal direction Y of the pad hem 50. By such formation, the leakage hem 60, which is located on the inner side of the pad pleat 50, can be in close contact with the wearer's thigh in a surface contact manner. In addition, the hem 50, 60 are separated from each other to prevent leakage of urine or the like while being in contact with the wearer. The elongation stress of the spacer hem 50 and the longitudinal direction Y of the leakage hem 60 can be set according to the number or thickness of each elastic member, and the magnitude relationship of the elongation stress is not limited to the above, and can be appropriately Settings.

The length dimension from the proximal edge 62 of the barrier hem 60 to the distal edge 63 is about 260-300 mm, preferably about 290 mm, and the length from the inner edge 52 of the pad hem 50 to the outer edge 53. The size is about 200-350 mm, preferably about 230-270 mm, and the length dimension of the leakage hem 60 is greater than the length dimension of the pad hem 50. By this dimensional relationship with the above-described elongational stress, that is, as shown in Fig. 6, the leakage hem 60 extends from the inner side of the liner hem 50. When viewed from the inside of the disposable diaper 10, only the leg openings formed by the leak-resistant hem 60 are visible, and the liner hem 50 is obscured by the leak-resistant hem 60 and is invisible. That is to say, since only one leg opening can be confirmed, it is easy to wear as long as the wearer's leg is passed. In addition, since there are two layers of hem, it is known to the wearer or his caregiver that it can prevent leakage of urine and the like, and therefore has a more secure feeling.

The leakage hem 60 is joined to the folded region by the front and rear joint regions 66, 67 at a position overlapping the front portions 45, 46 of the liquid-absorbent structure 41, so that even when the barrier elastic member 64 contracts, the distal end The edge 63 will not stand upright. Therefore, the liquid-absorbent structure 41 can always contact the wearer's body in a wide range, and a gap is not formed between the body and the body, so that the flow of urine or the like can be prevented from leaking from the waist opening or the like. Further, by setting the length dimension of the longitudinal direction Y of the front joint region 66 to be larger than the rear joint region 67, the liquid-absorbent structure 41 can be closely attached to the wearer's body on the front waist region 11 side, and thereafter On the side of the waist region 12, the standing region of the leak preventing hem 60 can be increased.

The fourth barrier elastic member 64d of the barrier elastic member 64 is positioned between the proximal edge 62 and the virtual bending line 65, so that the rigidity between the barrier elastic members 64d can be increased, and the leakage preventing hem 60 can be erected. The end edge 63 abuts the vicinity of the wearer's groin.

The longitudinal direction Y of the disposable diaper of the present invention has a length of about 400 to 520 mm, preferably about 410 to 450 mm, and is set to 415 mm in the present embodiment. Similarly, the longitudinal dimension Y of the underarm member 40 has a length of about 370 to 450 mm, preferably about 350 to 380 mm, and is set to about 375 mm in the present embodiment. The length dimension of the waist member 20 in the longitudinal direction Y before forming the front waist region 11 is about 80 to 130 mm, preferably about 85 to 125 mm, and is about 90 mm in this embodiment. The length dimension of the waist member 30 in the longitudinal direction Y after forming the back waist region 12 is about 150 to 190 mm, preferably about 155 to 185 mm, and is about 155 mm in the present embodiment.

The crotch member 40 is overlapped with a portion of the front and rear waist members 20, 30 of the disposable diaper 10, and the front waist member 20 is overlapped with the longitudinal length Y of the liquid-absorbent structure 41 by about 70 mm, and is overlapped at the rear waist portion. The member 30 is then overlapped by about 80 mm. That is, the liquid-absorbent structure 41 accounts for about 45% of the length dimension of the longitudinal direction Y of the front waist member 20 and about 24% of the rear waist member 30, respectively.

Further, at these overlapping positions, front and rear joining regions 66, 67 are formed, and the length in the longitudinal direction Y is set to be about 60 mm and about 45 mm, respectively. The length dimension of the longitudinal direction Y of the front joint region 66 is set to be about 45 to 70% of the length dimension of the longitudinal direction Y of the front waist region 11, preferably about 55 to 67%, and the longitudinal direction Y of the rear joint region 67. The length dimension is set to be about 30 to 50% of the length dimension of the longitudinal direction Y of the rear waist region 12, particularly about 29%.

The front and rear joint regions 66, 67 are formed so that the front and rear elastic members 23, 33 of the front and rear waist members 20, 30 overlap. That is, the portion where the front and rear elastic members 23, 33 overlap with the liquid-absorbent structure 41 is disposed apart from the virtual longitudinal center line P-P so that the contraction force does not act. However, the front and rear elastic members 23, 33 extend from the side edges 24, 34 toward the virtual longitudinal center line P-P, at least until they intersect the front and rear joint regions 66, 67. Therefore, it is possible to reliably press the front and rear joint regions 66, 67 against the body side of the wearer, thereby preventing a gap from being formed between the liquid-absorbent structure 41 and the wearer.

The disposable diaper 10 of the present invention has a small length dimension in the longitudinal direction Y, and is particularly suitable for use in a disposable diaper for infants and young children. In the case where the length dimension of the longitudinal direction Y of the disposable diaper 10 is set to be small, in order not to reduce the amount of absorption of urine or the like, it is preferable to not reduce the liquid-absorbent structure 41. As a result, as described above, the ratio of the liquid-absorbent structure 41 to the disposable diaper 10 becomes large. Since the rigidity of the liquid-absorbent structure 41 is generally large, the front and rear waist members 20, 30 may not easily adhere to the wearer's body once the proportion of the liquid-absorbent structure 41 is increased. However, in the present embodiment, by forming the front and rear joint regions 66, 67, the liquid-absorbent structure 41 can be adhered to the wearer in the front and rear waist regions 11, 12, and the disposable diaper 10 can be prevented from falling off. It is also possible to prevent a gap from being formed between the wearer and the wearer.

The length dimension of the longitudinal direction Y of the rear waist member 30 is set to be larger than the length dimension of the front waist member 20. In the disposable diaper 10, as shown in Figs. 1 and 6, the lower end region 30a of the rear waist member 30 extends toward the crotch region 13 side, and has a function of covering the buttocks of the wearer. Such a rear waist member 30 preferably extends across the longitudinal direction Y and covers the leg openings. That is, the lower end region 30a of the rear waist member 30 preferably extends from the distal end edge of the waist portion across the distal end edge 63 of the leak preventing hem 60 toward the crotch region 13 side. With such formation, the lower end region 30a covers the wearer's buttocks, and even if the excrement leaks from the leg opening, it can withstand the excrement. Therefore, it is possible to prevent excretion from adhering to the wearer or clothes. In particular, when the disposable diaper 10 is to be taken off from the sleeping infant or the like, the excrement is easily leaked from the opening of the leg, but it can be prevented.

In the longitudinal direction Y of the crotch member 40, front and rear outer elastic regions 27, 37 which are elasticized by the front and rear elastic members 23, 33 are formed, and are formed in the longitudinal direction Y of the front and rear outer elastic regions 27, 37. The front and rear inner elastic regions 28, 38. A portion of the anterior lateral elastic region 27 includes a front wing portion 48 that is externally located further outward than the rear wing portion 49. The elongation stress of the front and rear outer elastic regions 27, 37 is smaller than the elongation stress of the front and rear inner elastic regions 28, 38. In other words, by increasing the elongation stress of the front and rear inner elastic regions 28, 38, the liquid-absorbent structure 41 of the crotch member 40 can be closely attached to the body side of the wearer, and the disposable diaper can be prevented from falling off.

In order to elasticize the front and rear waist members 20 and 30 in the lateral direction X, a plurality of elastic yarns are used. However, the present invention is not limited thereto, and various elastic members such as an elastic sheet or a belt-shaped elastic body may be used. Similarly, a wide variety of elastic members can be used for the pad elastic member 55 and the barrier elastic member 64. The length of the intermediate portion 47 in the lateral direction X of the liquid-absorbent structure 41 is smaller than that of the front-rear portions 45 and 46. However, the intermediate portions 47 and the front-rear portions 45 and 46 may have the same length dimension in the lateral direction X. By.
