It extends from the edges 21a, 21b and the inner front and rear end edges 21c, 21d to the outside in the vertical direction Y and the horizontal direction X. Such a chassis 20 forms chassis side edges 23 and 24 extending in the longitudinal direction Y and outer front and rear edges 25 and 26 extending in the lateral direction X by the outer surface sheet 22. The first end edge of the present invention corresponds to the chassis rear end edge 26, and the second end edge corresponds to the chassis front end edge 25.

  A cover 60 is formed on the clothing side of the front waist region 5. The cover 60 is formed by bending the outer sheet 22 along the cover folding line 61. The cover folding line 61 is formed on the outer surface sheet 22 extending from the inner surface sheet 21 toward the chassis front end edge 25 and extends in the lateral direction X.

  As shown in FIG. 3, a liquid absorbing structure 30 is formed between the inner and outer surface sheets 21 and 22. The liquid-absorbing structure 30 includes a liquid-absorbent core material 31 formed of fluff pulp or the like, a liquid diffusion sheet 32 such as tissue paper covering the liquid-absorbent core material 31, and the liquid diffusion sheet 32 and the outer sheet 22. And a leakage prevention sheet 33 for preventing leakage of urine or the like to the chassis 20. The liquid absorbing structure 30 is located at least in the crotch region 7 and extends in the longitudinal direction Y from the crotch region 7 to the front and rear waist regions 5 and 6. The liquid absorption structure 30 is curved toward the longitudinal center line PP in the vicinity of the lateral center line QQ, and the diaper 1 is placed on the wearer's buttocks so that the diaper 1 is placed on the leg of the wearer. It is possible to stick around. The liquid absorption structure 30 includes liquid absorption side edges 34 and 35 extending in the vertical direction Y, and liquid absorption front and rear edges 36 and 37 extending in the horizontal direction X. The inner side opposite side edges 21a and 21b and the inner side front and rear end edges 21c and 21d of the inner surface sheet 21 extend from the liquid absorbing side edges 34 and 35 and the liquid absorbing front and rear end edges 36 and 37, and the liquid absorbing structure 30 becomes the inner surface sheet 21. It is configured to be covered with.

  The pair of waist straps 40 are positioned on the chassis side edges 23 and 24, respectively, and include a first string portion 41 positioned on the inner side in the lateral direction X and a second string portion 42 positioned on the outer side. The first and second string portions 41 and 42 are formed by a part of the outer sheet 22. That is, the outer surface sheet 22 is formed of a single fiber nonwoven fabric, and both end portions in the lateral direction X are folded back toward the body side along the string folding line 28 to form a folded portion 29. First and second string portions 41 and 42 are formed in the folded portion 29. The first and second string portions 41 and 42 are formed by cutting the outer sheet 22 and the folded portion 29 by inner and outer cutting lines 43 and 44 extending in the vertical direction Y and spaced apart in the horizontal direction X.

  The inner cutting line 43 has a front end 43 a in contact with the chassis front end edge 25 and a rear end 43 b separated from the chassis rear end edge 26. In the outer cutting line 44, both the front and rear ends 44a and 44b are separated from the chassis front and rear end edges 25 and 26. That is, the first and second string portions 41 and 42 are connected to the chassis 20 at the rear waist region 6 to form the base end edge 45, and are separated from the chassis 20 by the inner cutting line 43 on the opposite side. An end edge 46 is formed. Such 1st and 2nd string parts 41 and 42 are integrated in the base end edge 45 and the free end edge 46, without mutually cut | disconnecting.

  The inner cut line 43 has a longer distance from the chassis rear end edge 26 to the rear end 43b than the distance from the chassis rear end edge 26 to the rear end 44b of the outer cut line 44. In other words, the outer cutting line 44 has a deeper cut on the chassis rear edge 26 side. The rear end 43 b and the rear end edge 44 b are both formed between the liquid absorption rear end edge 37 and the chassis rear end edge 26.

  The first and second string portions 41 and 42 are attached with first and second string elastic members 47 and 48 that are elastically extendable in the longitudinal direction Y in a stretched state. Two first and second string elastic members 47 and 48 are arranged on both sides of each of the first and second string parts 41 and 42, and at least one of the string folding part 29 and the outer sheet 22. To be joined. The first and second string portions 41 and 42 are attached at portions other than the base end edge 45 and the free end edge 46 so as not to be elasticized at the base end edge 45 and the free end edge 46.

  A leg elastic member 27 is attached in the longitudinal direction Y in the longitudinal direction Y inside the inner cutting line 43 and between the inner cutting line 43 and the liquid absorption side edges 34 and 35, respectively. The chassis side edges 23 and 24 are made elastic so that they can be expanded and contracted. The leg elastic member 27 is attached between the folded portion 29 and the outer sheet 22 and joined to at least one of them. The leg elastic member 27 is located at least in the crotch region 7 and extends in the longitudinal direction Y from the crotch region 7 to the front and rear waist regions 5 and 6 in this embodiment.

  The chassis side edges 23 and 24 are cut at the inner cutting edge 43 to form both side edges of the cover 60. The cover 60 includes cover front and rear end edges 64 and 65 extending in the lateral direction X. The cover front end edge 64 is formed by the chassis front end edge 25, and the cover rear end edge 65 is formed by the cover folding line 61 of the outer surface sheet 22. It is formed. That is, the cover 60 is formed by the inner cutting line 43, the cover folding line 61, and the chassis front end edge 25, and the outer surface sheet 22 is partitioned into the cover 60 and the front waist region 5 by the cover folding line 61. Such a cover 60 forms a continuous portion integrally connected to the chassis 20 by the cover folding line 61 at the cover rear end edge 65, and a separation portion that can be separated from the chassis 20 by the chassis front end edge 25 at the cover front end edge 64. Form.

  A mechanical fastener hook 62 is formed on the clothing side which is the outer surface opposite to the outer sheet 22 forming the cover 60, and a mechanical fastener loop 63 is formed on the outer sheet 22 of the front waist region 5. And the loop 63 are detachable to form an engaging portion. The cover 60 has a length dimension in the longitudinal direction Y that is at least larger than the width dimension of the first and second string portions 41 and 42 so that they can be covered (see FIG. 2).

  In order for the wearer to wear the diaper 1 as described above, as shown in FIG. 1, the rear waist region 6 of the chassis 2 is placed on the back and the heel of the wearer, the crotch region 7 is on the crotch, and the front waist region 5 The chassis 2 is applied to the wearer so that each is located on the belly. When the chassis 2 is applied to the wearer, the pair of waist straps 40 are respectively turned to the clothing side of the front waist region 5, and the waist straps 40 are connected to each other to fix the chassis 2 to the wearer.

When the waist straps 40 are tied together, as shown in FIG. 2, the cover 60 is folded back along the cover folding line 61 to the clothing side of the front waist region 5, and the hook 62 of the cover 60 and the loop 63 of the front waist region 5. And engage.
Thus, since the waist string 40 can be covered with the cover 60, a wearer's hand etc. are not caught in the waist string 40. FIG. In particular, in this embodiment, the waist string 40 includes the first and second string portions 42, which are separated in the vertical direction Y, so that the wearer is easily caught, but this can be prevented. Moreover, since the knot of the waist string 40 can be covered, when the wearer is an infant, the wearer is prevented from unraveling the knot of the waist string 40 other than when the diaper 1 is attached or detached. Can do.

  The cover 60 can restrict the waist string 40 from being displaced up and down by the cover folding line 61 in the upper direction of the vertical direction Y and the engagement of the hook 62 and the loop 63 in the lower direction. Therefore, even when the crotch area becomes heavy due to urination or the like and the diaper 1 tries to move downward in the vertical direction Y, this movement can be suppressed. Since it can suppress that the diaper 1 moves below, it can prevent that a clearance gap is formed in the diaper 1 and a wearer's buttocks, and suppresses leakage of urine etc. from this clearance gap. be able to.

  The cover folding line 61 can be folded along the liquid absorption front end edge 36 or the inner surface front end edge 21c of the inner sheet 21 depending on the rigidity of the liquid absorbing structure 30 and the inner sheet 21, without providing a folding margin. Can do. In addition, since the cover 60 is defined by the cover folding line 61, the width dimension in the lateral direction X is the same between the outer sheet 22 and the cover 60, and no step is generated between them. If a step in the lateral direction X between the outer sheet 22 and the cover 60 occurs, the stepped portion may come into contact with the wearer's skin, which may cause skin trouble. However, in this embodiment, since there is no step portion, skin troubles caused by the contact of the step portion can be prevented.

  Since the waist string 40 includes the first string part 41 and the second string part 42, the rear ends 43b of the inner and outer cutting lines 43 and 44 forming the first and second string parts 41 and 42, By changing the separation distance from 44b to the chassis rear end edge 26, the connection positions of the first and second string portions 41 and 42 at the base end edge 45 are arranged so as to be shifted in the vertical direction Y. Since the separation distance from the rear end edge 26 of the chassis to the rear end 44b of the outer cutting line 44 is longer than the separation distance from the rear end 43b of the inner cutting line 43, the second cutting line 44 formed by the outer cutting line 44 is formed. The string portion 42 is substantially longer than the first string portion 41 formed by the inner cutting line 43. Moreover, the outer cutting line 44 is deeply cut with respect to the rear end edge 26, and when the diaper 1 is worn, the second string portion 42 has a chassis rear end edge rather than the first string portion 41. It comes to be located on the 26th side.

  When the diaper 1 is worn, the second string portion 42 is positioned on the chassis rear end edge 26 side, and the first string portion 41 is positioned closer to the chassis front end edge 27 side than the second string portion 42, whereby the second string A portion near the wearer's navel can be tightened by the portion 42, and a portion near the root of the wearer's leg can be tightened by the first string portion 41. Thus, since the diaper 1 can be fastened to the wearer at two places that are different from each other in the vertical direction Y, the diaper 1 can be further suppressed from shifting in the vertical direction Y in particular.

  Further, since the first and second string portions 41 and 42 can be tightened in a wide area in the longitudinal direction Y with respect to the wearer, the diaper 1 can be brought into close contact with the wearer with a correspondingly large area, and urine Etc. can be prevented. In particular, the infant grows quickly, and the diaper of the previous size may become small immediately. However, by providing the first and second string portions 41 and 42, the size can be adjusted in the vertical direction Y. Become. Moreover, even if it is a case where the diaper 1 is made to wear with respect to the wearer with a big body, it becomes possible to make the front-and-back waist areas 5 and 6 contact | adhere to a wearer in a wide area | region. The first string portion 41 positioned above the longitudinal direction Y of the waist string 40 is positioned in the vicinity of the wearer's waist and positioned below in consideration of close contact with the wearer and prevention of gap formation in the buttock. As for the 2nd string part 42, it is desirable to be located near the base of a wearer's leg.

  Since the first and second string portions 41, 42 are elasticized in the longitudinal direction by the first and second string elastic members 47, 48, the first and second string portions 41, 42 are pulled in the longitudinal direction. By tying, the front and rear waist regions 5 and 6 can be brought into close contact with the wearer by contraction of the first and second string portions 41 and 42. Moreover, the 1st and 2nd string parts 41 and 42 can follow the change of a wearer's waist by making the 1st and 2nd string parts 41 and 42 elastic. That is, especially in the case of an infant, the size of the waist changes before and after a meal, which can prevent the diaper from becoming difficult or loose.

  Since the elastic force of the first and second string elastic members 47 and 48 is not applied to the free end edge 46 of the waist string 40, the first and second string elastic members 47 and 48 are applied to the free end edge 46. Does not cause wrinkles. Since wrinkles do not occur in the free end edge 46, the free end edge 46 can be easily pinched with a finger, and the waist string 40 can be easily tied together.

  The first and second string portions 41, 42 can be formed by simply cutting the outer sheet 22 forming the chassis 20 with the inner and outer cutting lines 43, 44, and the first and second at the base edge 45. Since the cords 41 and 42 can be joined to the front waist region 5, the manufacturing is easier than attaching other cords to the chassis 20 using a separate joining means. Moreover, when the diaper 1 is manufactured with the longitudinal direction Y of the chassis 20 as the machine direction in the manufacturing process of the chassis 20, the inner and outer cutting lines 43 and 44 are formed in the same direction as the machine direction, and the machine direction and each The extension direction of the elastic member coincides. That is, since all these operations can be performed in the same direction, the diaper 1 can be manufactured easily and inexpensively.

  The fiber nonwoven fabric forming the outer sheet 22 preferably has a higher orientation ratio of the constituent fibers in the longitudinal direction Y than in the lateral direction X. Instead of the fiber nonwoven fabric as the outer sheet 22, a plastic film or a laminate sheet of the fiber nonwoven fabric can be used. In this case, the plastic film has a molecular orientation ratio in the vertical direction rather than the horizontal direction X. A higher Y is preferred. This is because the orientation of the fibers and molecules coincides with the direction of cutting the outer sheet 22 along the inner and outer cutting lines 43 and 44, thereby facilitating the cutting operation.

Although the waist string 40 is formed by two string parts of the first and second string parts 41 and 42, it may be formed by three or more string parts.
The hooks 62 and the loops 63 of the mechanical fastener are used as means for engaging the cover 60 with the clothing side of the front waist region 5, but the present invention is not limited to this. For example, a general engagement such as an adhesive tape is used. Combined means can also be used. Further, when the hook 62 is directly engaged with the fiber nonwoven fabric or the like on which the chassis is formed, the loop 63 may not be provided specially.
The rear waist region 6 corresponds to the first waist region and the front waist region 5 corresponds to the second waist region, but this may be reversed.

<Second Embodiment>
5 and 6 show a second embodiment of the present invention. FIG. 5 is a view similar to FIG. 1 showing the wearing state of the diaper 1, and FIG. 6 is a view similar to FIG. 4 showing a plan view of the diaper 1. The second embodiment is characterized in that the cover 60 is formed using a sheet different from the outer sheet 22. Since the configuration other than this feature is the same as that of the first embodiment, a detailed description thereof will be omitted.

  A cover 60 formed of a sheet separate from the outer surface sheet 22 is formed on the clothing side of the front waist region 5 of the outer surface sheet 22. The cover 60 joins the cover front end edge 64 to the outer sheet 22 via the joining means 66 to form a continuous part, and the cover rear end edge 65 is freed from the outer sheet 22 to form a separating part. ing. A hook 62 is formed on the body side of the cover 60 at the rear end edge 65 of the cover, and a loop 63 that can be engaged with the hook 62 is formed on the outer surface sheet 22. The hook 62 and the loop 63 form an engaging portion. In such a diaper 1, the waist string 40 is tied between the front edge 64 of the cover and the loop 63, and the cover 60 is covered from the clothing side of the tied waist string 40 so as to cover the waist string 40, and the hook 62 and the loop 63 are engaged.

  Since the cover 60 is a member different from the outer sheet 22, various materials can be selected as the cover 60. Moreover, the cover 60 can be set to various sizes. That is, the strength of the cover 60 can be changed or the cost can be reduced depending on the selected sheet material and size.

<Third Embodiment>
7 and 8 show a third embodiment of the present invention. FIG. 7 is a view similar to FIG. 1 showing the wearing state of the diaper 1, and FIG. 8 is a plan view of the diaper 1 and the same view as FIG. 4. The third embodiment is characterized in that the cover 60 is formed by cutting a part of the outer sheet 22 in the front waist region 5. Since the configuration other than this feature is the same as that of the first embodiment, a detailed description thereof will be omitted.

  A cover cutting line formed by perforations is formed on the outer surface sheet 22 of the front waist region 5. In the present invention, "perforation" means a notch formed by dotted cuts in a sheet or eyes having holes or slits formed in dotted lines, and the eyes are generally arranged in a dotted line. The sheet can be torn continuously through the dotted line of eyes. The cover cutting line includes both side edges 67 and 67 extending in the vertical Y direction and end edges 68 extending in the horizontal direction. The end edge portion 68 is formed along a line connecting both side edge portions 67, 67. The end edge portion 68 forms a cover rear end edge 65 and forms a separation portion that can be separated from the chassis 20. . The cover front end edge 64 facing the cover rear end edge 65 is integrally connected to the chassis 20 to form a continuous portion.

An intermediate sheet 70 is formed between the outer surface sheet 22 and the leakage preventing sheet 33 of the liquid absorbing structure 30, and the outer sheet 22 is cut along the side edges 67 and 67 and the end edge 68. When it is lifted away from the 20 side, the intermediate sheet 70 is exposed from the body side of the outer surface sheet 22.
A hook 62 of a mechanical fastener is formed on the body side of the cover 60, that is, the body side of the outer sheet 22 cut by the cover cutting line, and an engagement region 71 that engages with the hook 62 is formed on the exposed intermediate sheet 70. Is forming. The intermediate sheet 70 is formed of a fiber nonwoven fabric and can exhibit a loop function that can be engaged with the hook 62. Therefore, the engagement region 71 can be engaged with the hook 62 without forming a loop or the like, and the hook 62 and the engagement region 71 form an engagement portion.

  When the diaper 1 is worn, the outer sheet 22 is torn along the side edges 67 and 67 and the end edge 68 of the cover cutting line to form the cover 60. A waist string 40 is tied between the outer sheet 22 forming the cover 60 and the exposed intermediate sheet 70. When the waist string 40 is tied, the cover 60 is returned to the original position from the clothing side of the waist string 40, and the hook 62 is engaged with both the engagement areas 71. By forming the cover 60 in this manner, the tied waist string 40 can be covered, and by engaging the hook 62 and the loop 63, the movement of the waist string 40 in the vertical direction Y can be restricted. .

  In this embodiment, the outer sheet 22 can be used as the cover 60 without requiring a special member as the cover 60. For example, the diaper 1 of this embodiment can be realized by attaching the hook 62 to the outer sheet 22 and forming a perforation, and then laminating the outer sheet 22 with the intermediate sheet 70.

  Although the intermediate sheet 70 is formed between the outer sheet 22 and the liquid absorbing structure 30, the liquid absorbing structure 30 may be directly exposed without forming the intermediate sheet 70. In this case, the loop 63 that can be engaged with the hook 62 can be attached to the leakage prevention sheet 33. Further, although the cutting line is formed by perforation, it may be in a state of being cut from the beginning. Further, the cover front end edge 64 of the cover 60 can be separated from the chassis 2, and the cover rear end edge 65 is fixed to the chassis 2. However, as in the first and second embodiments, the cover front end edge 64 is used. May be fixed to the chassis 2 so that the rear end edge 65 of the cover can be separated from the chassis 2.

<Fourth Embodiment>
FIG. 9 shows a fourth embodiment of the present invention, and is a view similar to FIG. 1 showing a wearing state of the diaper 1. The fourth embodiment is characterized in that a string holding portion for holding the waist string 40 is formed on the outer surface sheet 22 on the body side of the cover 60. Since the configuration other than this feature is the same as that of the first embodiment, a detailed description thereof will be omitted.

  A pair of string holding portions 51 and 52 for passing the first and second string portions 41 and 42 are formed on the outer surface sheet 22 of the front waist region 5. Specifically, the string holding portions 51 and 52 are formed by a pair of slits 53 and 54 extending in the vertical direction Y, respectively. The slits 53 and 54 penetrate the outer sheet 22 in the thickness direction, and the length dimension in the longitudinal direction Y is the sum of the length dimensions in the lateral direction X of the first and second string portions 41 and 42, that is, the waist. The length of the entire string 40 in the lateral direction X is larger. The string holding portions 51 and 52 are opposed to each other in the horizontal direction X via the vertical center line PP, and are separated from the vertical center line PP by a substantially equal distance. The string holding portions 51 and 52 are formed at positions overlapping the liquid absorbing structure 30.

  The cover 60 has a length dimension located below the slits 53 and 54 in the longitudinal direction Y when folded back from the cover folding line 61 toward the clothing side of the front waist region 5. A hook 62 is formed on the cover 60, and a loop 63 that can be engaged with the hook 62 is formed on the outer surface sheet 22. These loops are used as engaging portions. The loop 63 is longer than the slits 53 and 54 in the longitudinal direction Y. It is located below. When such a loop 63 and the hook 62 are engaged, the knot of the waist string 40 and the slits 53 and 54 are covered by the cover 60.

  In such a diaper 1, the waist string 40 passes through the slits 53 and 54 of the string holding portions 51 and 52, and is tied between the string holding portions 51 and 52, that is, in the vicinity of the longitudinal center line PP. When the string holding portions 51 and 52 are formed in this way, the first and second string portions 41 and 42 of the waist string 40 are elasticized, and the first and second string portions 41 and 42 are wrinkled. The waist string 40 is hooked on the string holding portions 51 and 52 by this hook, and the waist string 40 can be prevented from coming off from the string holding portions 51 and 52. Since the string holding portions 51 and 52 are spaced apart from each other with respect to the vertical center line PP, when the waist string 40 is passed from the outside in the lateral direction X to the inside, The knot is located between the string holding portions 51 and 52, that is, in the vicinity of the vertical center line PP. Thus, by making a knot near the longitudinal center line PP, the pair of waist cords 40 can be pulled evenly, and one of the cords can be prevented from being pulled strongly. . When only one of them is pulled strongly, the elongation stress of the elastic member becomes large, and the tightening force of one becomes strong, and the irritation and discomfort to the skin becomes large.

  By forming the string holding portions 51 and 52, the movement of the waist string 40 in the vertical direction Y can be restricted, so that the diaper 1 can be further prevented from slipping down. Moreover, since the string holding portions 51 and 52 are formed by the slits 53 and 54 and the string holding portions 51 and 52 are covered by the cover 60, it is possible to prevent the wearer's limbs from being caught by the slits 53 and 54. it can.
