BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a view showing an example of a disposable wearing article of the present invention in which the front and rear waist regions of the disposable disposable diaper 1 are joined by a joining member. 2 is a plan view showing a state in which a pants are formed, FIG. 2 is a plan view of the unfolded disposable diaper 1, FIG. 3 is an exploded perspective view of the disposable diaper 1, and FIG. 4 is a cutaway end view of the IV-IV line of FIG. Fig. 2 is a cutaway end view of the VV line. In Figs. 2 to 5, each of the elastic bodies is shown in a state of being elongated in response to its contraction force. Fig. 6 is a view showing a state in which the disposable diaper 1 is worn from the side of the wearer.

As shown in Fig. 1, the disposable diaper 1 has a longitudinal direction Y and a lateral direction X, and has a front waistline region 11 and a rear waistline region 12, and a crotch region 13 between the front and rear waist regions 11 and 12, facing horizontally. The direction X extends before the trailing edges 14, 15 and the side edges 16 extending in the longitudinal direction Y. The front waistline region 11 is the first waistline region of the present invention, and the rear waistline region 12 is the second waistline region. The disposable diaper 1 can be formed into a pants type by connecting the hook member 81 attached to the rear waist region 12 and the loop member 82 attached to the front waist region.

As shown in FIG. 2 to FIG. 5, the disposable diaper 1 has an imaginary longitudinal center line PP that bisects the size of the lateral direction X and a virtual transverse center line QQ that bisects the size of the longitudinal direction Y, on the imaginary longitudinal center line PP. The above is roughly symmetrical. Regarding one of the constituent elements forming the symmetrical term, a part of the figure number is omitted.

As shown in Fig. 3, the disposable diaper 1 has a liquid permeable surface sheet 20 on the side of the body; a liquid-impermeable back sheet 30 on the non-body side (dressing side) on the opposite side thereof; and a sheet on the inside of the sheet 20 and 30 water absorbing absorbent bodies 40; and leakage preventing sheets 50 between the absorbent body 40 and the inner sheet 30. On the body side of the surface sheet 20, formed in the lateral direction X A pair of separated leak-proof hem 60. The body 10 of the present invention is formed by the surface sheet 20 and the inner sheet 30.

As the surface sheet 20, for example, a dot-bonded fiber nonwoven fabric having a mass of about 15 to 35 g/m ² can be used. As the inner sheet 30, a spunbond-meltblown-spunbond (SMS) fiber nonwoven fabric, a spunbonded nonwoven fabric, or a plastic sheet or a laminate of the fiber nonwoven fabric and the plastic sheet having a mass of about 10 to 30 g/m ² can be used. .

As the leakage preventing hem 60, a spunbond-meltblown-spunbond (SMS) fiber nonwoven fabric having a mass of about 10 to 30 g/m ² can be used. The front and rear end edges 61 and 62 of the leakage preventing hem 60 are laminated in line with the front and rear end edges 21 and 22 of the surface sheet 20, and are joined to each other by a hot melt adhesive (not shown). The outer edge 63 of the leakage preventing hem 60 is superposed on both side edges 33 of the inner sheet 30, and is joined to each other by a hot melt adhesive (not shown). The inner edge 64 of the leakage preventing hem 60 is disposed apart from the lateral direction X, and the inner edges 64 are superposed on the surface sheet 20. However, the inner edge 64 may be joined to the surface sheet 20 without being separated from the surface sheet 20. At the inner edge 64, the hemmed elastic body 65 extending in the longitudinal direction Y is retractably attached in an extended state. By attaching the hemmed elastic body 65, the inner edge 64 is separated from the surface sheet 20 and adhered to the wearer's skin, thereby preventing leakage of urine or the like to the outside of the disposable diaper 1.

The absorbent body 40 is at least located in the rear waistline region 12 and the crotch region 13, and in this embodiment, extends from the crotch region 13 toward the front and rear waist regions 11, 12. As shown in FIG. 5, the absorbent body 40 has a water absorbing core material 44; and a tissue paper 45, 46 covering the core material 44. As the core material 44, fluff can be used. Pulp, superabsorbent polymer particles, or a mixture of these. As shown in Fig. 2, the absorbent body 40 has a dimension in the lateral direction X of the front and rear waist regions 11 and 12 which is larger than the imaginary transverse center line Q-Q. More specifically, the absorbent body 40 is equal in size in at least the front and rear waist regions 11 and 12 in the lateral direction X, and in the crotch region 13, the size in the lateral direction X gradually decreases toward the imaginary transverse center line Q-Q.

The sheet sheets 20 and 30 and the absorber 40 are joined to each other by a joining means such as a hot melt adhesive (not shown). The absorbent body 40 has a smaller surface area than the inner sheets 20, 30, and the inner sheets 20, 30 extend from the front and rear end edges 41, 42 and the side edges 43 of the absorbent body 40. Therefore, in the longitudinal direction Y and the lateral direction X of the absorber 40, the front fins 74, 75 and the side flaps are not formed in the absorber 40. The side flaps have a first side flap 71 in the front waist region 11; a second side panel 72 in the rear waist region 12; and a lower flap 73 in the underarm region 13. A side panel elastic body 76 extending in the longitudinal direction Y is attached to the underarm side flap 73. The side panel elastic body 76 is joined to at least one of the front and back sheets 20, 30 via a bonding means such as a hot melt adhesive, and is contractible in the longitudinal direction Y in an extended state.

A leakage preventing sheet 50 is disposed between the absorber 40 and the back sheet 30. The leak-proof sheet 50 is a plastic film which is liquid-impermeable and non-air permeable. The area of the leakage preventing sheet 50 is made larger than that of the absorbent body 40. Therefore, it is possible to prevent urine or the like absorbed by the absorber 40 from leaking out of the disposable diaper 1.

The inner sheet 30 and the leakage preventing sheet 50 are made of a hot melt adhesive or the like. The joining means 90 are joined to each other. The side edges 93 of the joining means 90 are located closer to the inner side of the lateral direction X than the side edges 33 of the inner sheet 30, and are located closer to the inner side of the lateral direction X than the side edges 53 of the leakage preventing sheet 50. In the vicinity of the side edges 33, 53, a non-joining region 94 is formed in which no joining means 90 is formed. In the non-joining region 94, the inner sheet 30 and the leakage preventing sheet 50 are not joined to each other. A side panel elastic body 76 is attached to a position on the opposite side of the surface of the leakage preventing sheet 50 facing the inner sheet 30, which is superposed on the non-joining region 94. In this embodiment, a plurality of side flanks elastic bodies 76 having a string shape or a strand shape are attached, and the side flanks elastic body 76 and the joining means 90 are not overlapped. Further, at least a part of the side panel elastic body 76 may be located outside the lateral direction X of the joining means 90, and the part may be overlapped with the joining means 90. The bonding means 90 may be continuously formed on the back sheet 30 by, for example, coating by a coater, or may be formed intermittently by a spiral spray or the like.

The hook element 81 is attached to the rear waistline region 12 via the support sheet 83. The support sheet 83 has a fixing portion 84 fixed to the second side panel 72 and an extending portion 85 extending from the fixing portion 84 toward the outside in the lateral direction X of the side edge 16, and the hook member 81 is attached to the extending portion 85. The fixing portion 84 is located between the leakage preventing hem 60 and the inner sheet 30 (refer to FIGS. 3 and 4), and extends from the inner side edges 84a, 84b extending in the longitudinal direction Y and the front end edge 84c extending in the lateral direction X. , 84d is delimited.

The imaginary line R connecting the intersection A of the outer edge 84b of the fixing portion 84 and the front end edge 84c and the side edge 43 of the absorber 40 and the intersection B of the virtual transverse center line QQ is located on the second side flap 72 and the underarm side flap. Slice 73 on. That is, the imaginary line R does not overlap the absorber 40 but is located outside the lateral direction X thereof.

The side panel elastic body 76 has a rear end 76b that faces the rear waistline region 12 more than the imaginary line R. That is, the side panel elastic body 76 and the imaginary line R cross each other. The front end 76a of the side panel elastic body 76 extends from the crotch region 13 toward the front waistline region 11 side.

The bending rigidity of the first and second side flaps 71 and 72 and the crotch side flap 73 in the longitudinal direction Y is about 0.10 to 0.20 N/m, and the bending rigidity in the lateral direction X is about 0.05 to 0.10 N/m. These bending rigidity were measured by the following methods.

<Method for Measuring Bending Rigidity>

The bending stiffness was measured by the KES test. The KES test was carried out using a KES-FB2-AUTO-A automatic pure bending tester (KATO TECH). 10 mm × 10 mm was used as a sample piece in the range including the imaginary line R, and the measurement was performed under the conditions of a temperature of 20 ° C and a humidity of 60%. More specifically, as a sample piece, a portion of the underarm side panel 73 in which the inner sheet 30, the leakage preventing sheet 50, and the leakage preventing hem 60 are laminated is cut into a longitudinal direction Y of 10 mm and a lateral direction X. Used for 10mm.

Such a sample piece was attached to a KES tester and measured with a curvature (1/cm) using a SEN10 sensor having a torque sensitivity of 10 gf/cm/10 V in the full range. The bending rigidity in the longitudinal direction Y and the transverse direction X was measured for the sample piece.

As shown in Fig. 6, the disposable diaper 1 is coupled to the front and rear waist regions 11 and 12 by joining the hook members 81 to the loop members 82, so that the pants-type diaper 1 can be worn by the wearer H. When the diaper 1 is worn with such urination, the absorbent body 40 absorbs the urine and becomes heavy, causing the entire disposable diaper 1 to be pulled downward. At the intersection A of the one end of the imaginary line R, the diaper 1 is held by the hook element 81 at the waist of the wearer, and at the intersection B of the other end of the imaginary line R, due to the disposable diaper 1 Pulled downward, the disposable diaper 1 is pulled along the imaginary line R. The intersection A is reliably held by the wearer H, and the bending rigidity of the second side flap 72 and the underarm flap 73 in the longitudinal direction Y of the imaginary line R is about 0.10 to 0.20 N/m. The bending rigidity of the direction X is about 0.05 to 0.10 N/m, so that even if there is urination, the disposable diaper 1 does not sag due to the weight of the urine. Since the disposable diaper 1 does not sag due to the weight of the urine, the diaper 1 does not have a waist-down of the wearer, and the wearing state can be maintained in close contact with the wearer.

Since the bending rigidity of the second side panel 72 and the underarm side panel 73 is set to the above range, the side panels are less likely to be bent, and it is prevented from being turned up toward the back sheet 30 side or being caught on the surface sheet 20 side. Therefore, the second side flaps 72 and the underarm side flaps 73 can be covered along the buttocks of the wearer. By covering the wearer's buttocks with side sheets, even if the excrement leaks out of the side panels, it can be held and prevented from adhering to the clothes. Further, by covering the buttocks with the flaps, it is also possible to provide the disposable diaper 1. Further, in the case where the fins are wound on the side of the surface sheet 20, there is a possibility that the portion to be caught enters the inside of the disposable diaper 1 and adheres to the excrement. However, it is also possible to prevent such situations from happening.

In the disposable diaper 1 as described above, the imaginary line R drawn is closely adhered to the base of the thigh of the wearer H when worn. Since the imaginary line R is in close contact with the base of the thigh which is the action base of the foot, the operation of the foot of the wearer H is not hindered, and leakage of urine or the like can be prevented. Moreover, the disposable diaper 1 can be held by the base of the thigh of the wearer H by the imaginary line R, and the sliding of the disposable diaper 1 can be prevented. The bending rigidity of the second side flap 72 and the crotch side flap 73 in the longitudinal direction Y is larger than 0.20 N/m, and the bending rigidity in the lateral direction X is larger than 0.10 N/m, and the wear is caused by the entire hardening. The tension acting on the side sheets does not concentrate on the imaginary line R, so that the imaginary line R of the side sheets does not adhere to the wearer's body.

The imaginary line R is located outside the lateral direction X of the absorber 40 and does not overlap the absorber 40. Therefore, the imaginary line R is not cut off by the absorber 40. In the case where the imaginary line R overlaps with the absorber 40, since the pulling force from the intersection A to the intersection B is cut off, the tension state of the side sheets collapses, and the side sheets are turned toward the outside of the disposable diaper 1. Or the possibility of being involved in the inside. In the present invention, since the stretched state of the side sheets can be maintained by the imaginary line R, there is no possibility that the side sheets are turned up or caught.

Since the imaginary line R intersects with the side panel elastic body 76, the side panel elastic body 76 is held by the imaginary line R, and it is possible to prevent the side panel elastic body 76 from falling down toward the lower side. Therefore, the side panel elastic body 76 and the underarm side flap 73 to which the side panel elastic body 76 is attached can be in close contact with the squirrel portion of the wearer, and the excretion can be prevented from leaking out of the disposable diaper 1. Further, when the front and rear end edges 14, 15 of the disposable diaper 1 are pulled up, the diaper of the disposable diaper 1 The lower region 13 is also pulled up along the imaginary line R, so that it is easy to organize the wearing state.

The side panel elastic body 76 is attached to the non-joining region 94 where the joining means 90 is not formed. In the non-joining region 94, the bending rigidity is small compared to the region in which the joining means 90 is formed. Therefore, along the contraction of the side panel elastic body 76, the underarm side flap 73 can be softly adhered to the wearer's foot. Further, since the side panel elastic body 76 is attached to the leakage preventing sheet 50, it can be separated from the inner sheet 30 and adhered to the wearer, so that it can be easily adhered. Further, since the side panel elastic body 76 is attached to a region having a small bending rigidity, when the disposable diaper 1 is pulled up, the pulling force is easily transmitted to the side panel elastic body 76, and the underarm side flap 73 can be closely attached to the wearing. User's groin. In a case where a part of the plurality of side panel elastic bodies 76 overlaps with the engaging means 90, the overlapped side panel elastic body 76 pushes the leakage preventing sheet 50 and the back sheet 30 toward the wearer side, and can be adapted to Since the side flap elastic body 76 of the joining means 90 is superposed, the underarm side flap 73 can be more closely adhered to the wearer's body.

As the side panel elastic body 76 of this embodiment, an elastic yarn is used. However, the elastic yarn is not limited thereto, and a sheet having elasticity or the like may be used. Further, the rear end 76b of the side panel elastic body 76 is located closer to the rear waistline region 12 than the imaginary line R. The rear end 76b herein refers to the rear end of the portion that substantially generates elasticity in the side panel elastic body 76.

The imaginary line R is separated from the side edge 16 of the main body 10 by a size of about 5 to 20 mm. Furthermore, since the imaginary line R and the side edges 16 do not necessarily form parallel to each other, the closest portion is made to be about 5 mm. Large, and the most separated part is made smaller than about 20mm. Therefore, the second side flaps 72 and the underarm side flaps 73 can stably cover the wearer's buttocks. In the case where the separation size is smaller than 5 mm, the flap is easily caught in the inner side of the disposable diaper 1, and in the case of being larger than 20 mm, it is pulled by the action of the wearer's foot, and the disposable diaper 1 becomes easily biased. shift.

As shown in FIG. 2, in the main body 10, the dimension W1 of the imaginary transverse center line QQ is about 180 to 300 mm, and in this embodiment, it is about 205 mm. In the absorber 40, the size W2 of the imaginary transverse center line QQ is about 70 to 100 mm. In this embodiment, it is made to be about 80 mm. The size W2 of the absorber 40 is about 0.2 to 0.4 times the size W1 of the main body 10. That is, W2/W1=0.2~0.4. Thereby, the underarm flap 73 does not get caught inside the disposable diaper 1 and can cover the wearer's buttocks.

The angle between the imaginary line R and the imaginary transverse center line Q-Q is about 45 to 60 degrees. Therefore, the entire buttocks can be covered by the second side flaps 72 and the underarm flaps 73. In the case where the angle is smaller than 45°, the imaginary line R is located closer to the thigh than the wearer's groin, and the diaper 1 is pulled toward the lower side in accordance with the action of the wearer, causing the diaper 1 to face downward. shift. In the case where the above angle is larger than 60°, the imaginary line R is located on the wearer's buttocks and cannot cover the buttocks sufficiently.

When the dimension L1 of the longitudinal direction Y of the back waistline region 12 is compared with the dimension L2 from the trailing edge 15 of the disposable diaper 1 to the imaginary transverse centerline Q-Q, the dimension L1 is about 0.4 to 0.7 times that of L2. That is, L1/L2 = 0.4 to 0.7. The rear waist region 12 refers to the portion in which the side edges extend in parallel. In the case where the above L1/L2 is smaller than 0.4, the second side flap 72 The area of the wearer's buttocks is not sufficiently covered, and the second side flap 72 is easily caught inside the disposable diaper 1. When L1/L2 is larger than 0.7, the area of the second side flap 72 is excessively large, which is pulled by the action of the wearer's foot, and the disposable diaper 1 is easily displaced.

The waist region 12 is defined by the imaginary parallel line SS and the imaginary line R parallel to the imaginary transverse center line QQ along the lower end edge of the support sheet 83 and the side edge 43 of the absorber 40 after the support sheet 83 is mounted. The region S1 is compared with the region S2 defined by the imaginary line R and the side edge 16 and the imaginary transverse center line QQ, and the region S2 is about 0.41 to 0.8 times the region S1. That is, S2/S1=0.41~0.8. The region S1 is easily adhered to the wearer's buttocks, and the region S2 is separated from the wearer's buttocks to cover the buttocks. When the S2/S1 is 0.41 hours, the area covering the buttocks becomes smaller and the wearer's buttocks cannot be adequately covered. Moreover, it is easy to get caught in the inner side of the disposable diaper 1. When S2/S1 is larger than 0.8, the area S2 covering the buttocks becomes too large, causing the action of the wearer's foot to be pulled, so that the disposable diaper 1 is easily displaced. Moreover, when the disposable diaper 1 is worn, there is a possibility of hooking to the wearer's foot, resulting in difficulty in wearing.

The disclosure of the present invention described above is at least approximately as follows.
