    CLOTHING ITEM
    [0001] The present invention relates to articles of clothing and more particularly to articles of clothing such as disposable diapers, toilet training pants, diapers for brief incontinence, and others.
    [0002] Conventionally, disposable diapers formed with a waist opening and leg openings in which the waist opening is provided along a periphery thereof with elastic waist members are known. For example, the diaper shown in JP 10-314220 A (LPT 1) includes an assembled upper-waist region formed in the vicinity of the waist opening, an assembled lower-waist region formed adjacent to the assembled region surrounding the upper waist on the side of the region between legs and a liquid-absorbent structure partially overlapping the joined region of the lower waist. [Patent Literature] [LPT 1] JP 10-314220 A
    [0003] The region gathered at the upper waist and the region gathered at the lower waist are formed on the upper surface and the posterior leaves and with elastic members sandwiched between these leaves. Under the effect of these elastic members, the upper surface and the posterior leaves necessarily form a plurality of folds extending in a longitudinal direction of the diaper. While these folds should be softened merely by placing the diaper on the user's body, a longitudinal dimension from the waist opening to the liquid-absorbent structure is relatively large and thus it will be difficult for the diaper to smooth these folds over its entire length.
    [0004] An object of the present invention is to provide an improved garment to facilitate folds created in the front waist region as well as in the rear waist region to be gently removed.
    [0005] According to the present invention, an article of clothing is provided having a longitudinal and a transverse direction including: - a chassis including a side facing the user's body, a side facing the user's clothing, a region front waist, a rear waist region, and a region between legs extended between the front and rear waist regions; - a liquid-absorbent structure extended across the region between legs in the front and rear waist region; and - elastic waist members attached to the front and rear waist regions under tension and in a stretched manner in the transverse direction where the liquid absorbent structure includes a liquid absorbent core, a cover sheet used to cover the core and the front end flaps and rear seated outside the front and rear ends of the core as seen in the longitudinal direction and formed from the cover sheet.
    [0006] The characteristics according to the present invention reside in: - the liquid-absorbent structure overlapping the front and rear waist regions has a dimension in the longitudinal direction corresponding to 70 to 90% of a dimension in the longitudinal direction of the respective regions of front and rear waist and the front and rear waist regions extended from one end of the waist opening of the region between legs and at least including first regions at least partially overlapping the front and rear extreme flaps and second extended regions adjacent to the first regions ; and - first regions being elasticized over their entire area by first elastic members in the transverse direction, the second regions respectively including non-elastic zones overlapping the core and elastic zones seated outside the non-elastic zones as seen in the transversal direction and elasticized for seconds elastic waist members where the clamping force of the first regions is set to be lower than that of the second regions.
    [0007] According to a configuration of the present invention, the clamping force of the first regions corresponds to 70 to 90% of the clamping force of the second regions.
    [0008] According to another configuration of the present invention, the front and rear waist regions are respectively divided into first regions and second regions.
    [0009] According to yet another configuration of the present invention, the front and rear waist regions respectively include extended third regions adjacent to the second regions on the side of the member between legs, the front and rear waist regions respectively divided into first, second regions. regions and third regions and the clamping force of the third region being set to be less than that of the second region.
    [00010] According to yet another configuration of the present invention, the clamping force of the second regions is set to be greater than that of the third regions by 20 to 50%.
    [00011] According to the present invention, the liquid-absorbent structure overlapping the front and rear waist regions has a dimension in the transverse direction corresponding to 70 to 90% of a dimension in the longitudinal direction of the respective front and rear waist regions and the front and front waist regions being respectively divided into first regions seated in the vicinity of the waist opening and second regions extended from the first regions towards the region between legs where the respective first regions have the tightening force set to be lower than that of the respective second regions. With this configuration, the folds of the first regions can be easily removed as the waist opening is enlarged. The absorbent core overlaps the second regions and the non-elastic zones are formed in the said overlapping zones in order to restrict the creation of folds in the second regions.
    [00012] For a better understanding of the present invention, detailed reference will be made to it, with respect to the attached drawings, presented in an exemplary and non-limiting character, in which: - Figure 1 is a perspective view of a diaper as a example of articles of clothing; Figure 2 is a plan view developed from the diaper according to a first configuration of the present invention as seen from a side facing the user's body; - Figure 3 is a sectional view taken along the line ll-lll of Figure 2; - Figure 4 is a sectional view taken along line IV-IV in Figure 2; - Figure 5 is an exploded view corresponding to Figure 2; Figure 6 is a plan view developed from the diaper according to a second configuration of the present invention as seen from the side facing the wearer's clothing. (First Configuration)
    [00013] Figures 1 to 5 illustrate the first configuration of the present invention and details of it with a better description of a disposable diaper as an example of the invention.
    [00014] Figure 1 is a perspective view showing a diaper 10 having a waist opening and leg openings maintained in an annular state. Figure 2 is a plan view developed from the diaper as seen from its side facing the user's body. The respective elastic elements are stretched against their contractile force in order to keep the diaper 10 in a level condition. Figure 3 is a sectional view taken along the line ll-lll of Figure 2. Figure 4 is a sectional view taken along the line IV-IV and Figure 5 is an exploded view corresponding to Figure 2. In the right half of Figures 3 and 4 on an imaginary longitudinal central line PP, the respective elastic members are shown to be in a contracted state.
    [00015] Diaper 10 has a longitudinal direction Y, a transverse direction X. a side facing the user and a side facing the user's clothing and including a front waist region 11, a rear waist region 12 and a region between legs 13 extended between the front and rear waist regions 11, 12. The diaper 10 has the imaginary longitudinal centerline PP forking a dimension of it in the transverse direction X and a transversal center line QQ forking a dimension of the same in the longitudinal direction Y. Diaper 10 is substantially symmetrical in shape over the imaginary longitudinal centerline PP.
    [00016] Diaper 10 includes front and rear waist members 20, 30 spaced apart in the longitudinal direction Y and a member between legs 40 by means of which the front and rear waist members 20, 30 are connected. The front and rear waist members 20, 30 are connected along the respective opposite side edges 21, 21, 31, 31 to form seams 14. These seams 14 define a waist opening and a pair of leg opening. The front and rear waist members 20, 30 respectively have outer ends 22, 32 cooperating with each other to form a peripheral edge of the waist opening and respectively having inner ends 23, 33 overlapping the region between legs 13 and thus partially forming the openings of the legs. The front and rear waist members 20, 30 respectively comprise upper sheets 23, 24 seated on the side facing the user's body and posterior sheets 25, 35 seated on the side voted for the user's clothing.
    [00017] Having attached to the front waist member 20 along respective side edges 21, 31, the rear waist member 30 includes a waist adjustment region 30a overlapping the front waist member 20 to cover the user's waist and an extension region 30b extended from the waist adjustment region 30a towards the region between legs 13. An edge between that waist adjustment region 30a and the extension region 30b is defined by an imaginary line 70, An end dimension the outer edge of the waist 32 to the imaginary line 70 in the transverse dimension X is substantially the same as that of the outer end of the waist 22 of the front waist member 20 to the inner end of the front waist 23 on the side of the region between legs 13.
    [00018] A region extended from the outer edge of the front waist 22 of the front waist member 20 to the inner end of the front waist 23 in the region between legs 13 is defined as the front waist region 11, an extended region from the outer edge of the rear waist 32 from the rear waist member 30 to the imaginary line 70, that is, the waist adjustment region 30a being defined as the rear waist region 12, and a region extended from the imaginary line 70 to the inner end of the front waist being defined as the region between legs 13. The front and rear waist members 20, 30 cooperate with a part of the member between legs 40 to form a chassis according to the present invention.
    [00019] The limb between legs 40 includes a liquid absorbent structure 41, a pair of separating sheaths 50 and one and a pair of leakage barrier sheaths 60. The absorbent structure 41, in turn, includes a liquid absorbent core 42, an inner sheet 43 seated on the side facing the user's body to cover the inner surface of the core 43, a leak barrier sheet 44 adapted to cover the outer surface of the core 42 and an outer sheet 45 seated on the side facing the user body to overlay leak barrier sheet 44. Core 42 may be formed, for example, from cellulose pulp and / or particles of super-absorbent polymer. Said core 42 has its dimension in the transversal X direction gradually reduced towards the imaginary transversal central line Q-Q to define a generally hourglass shape.
    [00020] Core 42 has a dimension in the longitudinal direction Y being in a range of approximately 300 to 400 mm, preferably in the range of approximately 335 to 380 mm. The inner sheet 43 and the leakage barrier sheet 44 are respectively sized to be larger than the size of the core 42 in the longitudinal direction Y, specifically, in a range of approximately 350 to 450 mm, preferably in the range of approximately 375 to 430 mm. Said absorbent structure 41 is formed on the outside of the core 42 as seen in the longitudinal direction Y with the front and rear end flaps 46, 47 each being formed of the inner sheet 43, the leak barrier sheet 44 and the outer sheet 45. On these flaps front and rear end 46, 47, the inner sheet, the leak barrier sheet 44 and the outer sheet 45 are bonded together with suitable adhesive as well-known heat-melt adhesives.
    [00021] The core 42 is formed on the outside of it, as seen in the cross-sectional direction X with a pair of side flaps 48 (or separation sheaths) including the respective parts of the inner sheet 43, the leak barrier sheet 44 of the outer sheet 45 extended externally beyond the periphery of the core 42. The sheets are bonded together with appropriate adhesives, such as well-known heat-melt adhesives. Each of the side flaps 48 has its dimension in the transverse direction X in a range of approximately 170 to 220 mm, preferably approximately 190 mm.
    [00022] As the inner sheet 43, for example, a liquid-permeable fibrous non-woven material may be used. More specifically, for example, a non-woven fibrous material through air, a non-woven fibrous non-woven material, or a continuous filament fibrous non-woven material, each having a weight per unit area in a range of approximately 10 to 25g / m2 can be used.
    [00023] As a leak barrier sheet 44, a plastic film impermeable to liquid, but permeable to moisture can be used in such a way that this sheet covers at least the entire bottom surface of the absorbent structure 41 and thus being able to prevent body waste such as urine from leak out of diaper 10,
    [00024] As an outer sheet 45, for example, a non-woven material impermeable to liquid, but permeable to moisture can be used. More specifically, like this outer sheet 45, a continuous filament fibrous (SMS) nonwoven material, continuous filament blowing, a bonded point fibrous nonwoven material or a continuous filament bonded fibrous nonwoven material each having a weight per unit area in a range of approximately 10 to 25g / m2 can be used.
    [00025] The separation sheaths 50 include the inner sheet 43 and the outer sheet 45 constituting the side flaps 48 and the elastic separating members 51 fixed inside the respective ends (sleeves) formed of the outer sheet 45. Each of the members of separation 51 include one or more elastic threads or lines extended in the longitudinal Y direction and tightly contracted under tension.
    [00026] The leakage barrier sheaths 60 are formed by folded parts of the outer sheet 45 extending externally beyond the separation sheaths 50 substantially in a Z shape above the absorbent structure 41. Between the layers defined by the fold of the outer sheet, in this way , the elastic barrier members 61 each including two or more elastic threads or lines extended in the longitudinal direction Y and tightly contracted under tension. Each of these leakage barrier sheaths 60 is attached at opposite ends of them as seen in the longitudinal direction to the associated separation sheath 50 and not attached to them in the remaining region. As a result, these leakage barrier sheaths 60 rise in the separation sheaths 50 under the contractile force of the elastic barrier members 61.
    [00027] As illustrated in Figure 3, the separation sheaths 50 and the leakage barrier sheaths 60 rise so that the leakage barrier sheaths 60 can be spaced from the inner sheet 43 when the diaper is worn on the user's body. In this way, the leakage barrier sheaths 60 come into contact with areas in the vicinity of the user's inguinal regions. The separation sheaths 50 are also elasticized in the longitudinal direction Y under the effect of the elastic separation members 51 so that the separation sheaths 50 are curved towards the diaper wearer's body and are in close contact around the wearer's thighs . Specifically, the leakage barrier sheaths 60 cooperate with the separation sheaths 50 to form double sheaths serving to prevent body residue such as urine from leaking out of the periphery of the leg openings.
    [00028] The outer sheet 45 is attached along the front and rear ends 40a, 40b of the member between legs 40 and thus the front and rear waist members 20, 30 being connected to the member between legs 40, The absorbent structure 41 on the member between legs 40 it is fixed so as to overlap the front and rear waist regions 11, 12. A dimension of the absorbent structure 41 in the longitudinal direction Y overlapping the front and rear waist regions 11,12 will be in the range of approximately 70 to 90% their respective dimensions in the longitudinal Y direction of the front and rear waist regions 11, 12.
    [00029] As illustrated in Figure 2, the front and rear ends 40a, 40b of the limb between legs 40 are covered with the inner and outer leaves 24, 25, 34, 35 folded in the imaginary transverse center line QQ on the upper surface of the limb between legs 40, By covering the front and rear ends 40a, 40b with these sheets, it will be possible to prevent the core component material 42 from deteriorating, on the one hand, making it possible to protect the user from experiencing any type of problem due to contact of the ends front and rear 40a, 40b with the user's skin.
    [00030] The front and rear waist members 20, 30 extend from the outer ends of the waist 22, 32 towards the region between legs 13 and including the first regions 71 overlapping the front and rear end flaps 46 of the absorbent structure 41 , 47 and the second regions 72 adjacent to the respective first regions 71. The first and second regions 71,72 which sit side by side are respectively connected by associated imaginary lines 73. Both first and second regions 71, 72 circumferentially extend in the regions front and rear waist 11.12 to form an annular shape.
    [00031] According to the present configuration, a distance in the longitudinal direction Y from the respective outer ends 22, 32 from the front and rear waist members to the front and rear extreme flaps 46, 47 of the absorbent structure 41, that is, a dimension of the respective extreme flaps 46, 47 in the longitudinal direction Y being approximately 20 mm. A dimension in the longitudinal Y direction of the respective first regions 71 is approximately 23 mm and the dimension of the respective second regions is approximately 67 mm. The sum of the dimensions of the first and second regions 71, 72 in the longitudinal direction Y respectively represents a dimension of the front and rear waist regions 11, 12, that is, approximately 90 mm. Accordingly, the size of the respective first regions 71 in the longitudinal Y direction corresponds to approximately 26% of the front and rear waist regions 11, 12, respectively.
    [00032] Between the respective front and rear leaves 24, 25, 34, 35 of the front and rear waist members 20, 30, first elastic waist members 81 and second elastic waist members 82 are attached to the first regions 71 and second regions 72, respectively. Each of the first elastic waist members 81 includes two or more elastic threads or threads continuously extending from the side edges 21, 31 to the opposite side edges 21, 31. According to the present configuration, four (4) elastic threads or threads, each having a fineness of approximately 470dtex they are fixed so that they are spaced from each other in the longitudinal direction Y in an interval of approximately 5.5 mm. The first elasticized waist members 81 can be attached to the first regions 71 under tension in a contracted manner in the transverse direction X to elasticize the first regions in the transverse direction X.
    [00033] The second regions 72 are formed with non-elastic zones 72a overlapping the core 42 and elastic zones 72b outside the non-elastic zones 72a as seen in the cross-sectional X where the second elastic waist members 82 are fixed to the elastic zones 72b in a way that the second elastic members 82 may have respectively inner ends 82a overlapping the core 42 and the outer ends 82b seated on the side edges 21, 31. According to the present configuration, eleven (11) elastic threads or threads each having a fineness in the band from approximately 470 to 620dtex are used as second elastic members of waist 82 and these elastic threads or threads are spaced from one another in the longitudinal Y direction in an interval of approximately 5.5 mm. The second elastic waist members 82 may be attached to the respective elastic zones 72b under tension in a contracted manner in the transversal direction X to elasticize the elastic zones 72b of the respective second regions 72 in the transversal direction X. The non-elastic zones 72a have no second members waist elastics 82 attached to them, and as a consequence, these non-elastic zones 72a are not elasticized.
    [00034] The extension region 30b of the rear waist member 30 is provided with elastic members of the extension region 37 fixed therein so that these elastic members 37 can have inner ends 37a overlapping the core 42 and outer ends 37b seated on the side edges 31. According to the present configuration, each of the elastic extension members 37 includes two (2) elastic threads or threads having a fineness of approximately 470dtex and fixed in the extension region 30b so that they are spaced from each other in an interval of 25 mm in the longitudinal direction Y. The elastic members of the extension region 37 can be attached to the extension region 30b under tension and in a contracted manner in the transversal direction X to elasticize the extension region 30b in the transversal direction X. Similar to the second ones regions 72, the extension region 30b is also locally free from the effect of the elastic members. Specifically, none of the elastic members are provided in a defined zone between the inner end 37a and the opposite inner end 37a and are not elastic in this intermediate zone.
    [00035] In the front and rear waist regions 11.12 constructed as described above, the clamping force of the first regions 71 is less than the clamping force of the second regions 72.
    [00036] The clamping force was measured by the following method:
    [00037] From diaper 10 having the opposite side edges 21, 31 connected together, the first and second regions 71, 73 were respectively cut to prepare test pieces. For regions completely occupied by the absorbent structure 41, they were cut together with the absorbent structure 41 so that the test pieces could include any part of the absorbent structure 41. In each test piece contracted under the effect of the associated elastic member, a distance from the inner end of the sewing line 14 to the inner end of the opposite sewing line 14 was represented by SW and the corresponding distance in each test piece stretched in the transversal direction X against the contractile force of the associated elastic member represented by PW. The dimension of each test piece in the longitudinal direction was represented by L.
    [00038] The test piece was fixed by AUTOGRAPH (manufactured by Shimadzu Corporation of Japan) with an inter-mandrel distance set to the SW and stretched at a mandrel speed of 100 mm / min. at a distance of 0.85 x PW. From this point on, the test piece was moved back in the inverted direction at the same speed and the contractile force measured in one moment the spindle distance reached 0.65 x PW being determined as an entire clamping force Fa (N). From the entire clamping force Fa (N) / L x 10, a clamping force per unit area F was calculated. The clamping force measured at the inter-mandrel distance of 0.65 x PW was specified as the entire clamping force Fa (N) on the basis of the empirical knowledge that 65% PW is an average waist size of the diaper user.
    [00039] The measurement result indicated that the clamping force F of the first region 71 was approximately 0.22 while the clamping force of the second region 72 was approximately 0.30. More specifically, the clamping force F of the first region 71 was in a range of approximately 0.20 to 0.32 while the clamping force F of the second region 72 was in a range of approximately 0.28 to 0.36. From that result, the clamping force of the first region 71 is approximately 70 to 90%, preferably in a range of approximately 74 to 76% of the clamping force of the second region 72.
    [00040] The clamping force of the first regions 71 established to be less than that of the second regions 72 as described above facilitates the first regions 71 to be enlarged when the front and rear waist members 20, 30 are extended to wear the diaper 10 in the user's body. In particular, the waist opening may be sufficiently wide to facilitate the diaper to be worn on the user's body. Said diaper, 10 can be easily worn on the user, seated up, for example, the baby lying face up. If the folds remain in the front and rear waist regions 11, 12 when diaper 10 is worn on the user lying face up, these folds will rub the user's skin and uncomfortably irritate the skin. In the diaper 10 according to the present invention, said undesirable folds can be substantially removed when the diaper 10 is worn on the user's body.
    [00041] The first regions 71 respectively have the dimension in the longitudinal Y direction reduced by approximately 26% of the front and rear waist regions 11, 12 so that the first regions 71 can be sufficiently enlarged to remove the folds in those first regions 71 when the diaper is extended with the opening of the waist held by the user's hands or by those who care for them. It should be appreciated that the size of the respective first regions 71 in the longitudinal direction Y will not be limited to the aforementioned value, and, for example, by establishing this dimension at 20 to 30% of the dimension of the front and rear waist regions 11, 12, the folds can be easily removed and, in addition, the first regions can be placed in close contact with the user's body.
    [00042] With diaper 10 worn on the user's body, even if the folds on the front and back sheets in the first 71 regions do not remain completely removed and coming into direct contact with the user's skin, these folds will come smoothly in contact with the skin of the user since the clamping force in the first regions 71 is previously controlled to be relatively low. As a result, deep impressions of these folds should not be left on the user's skin. In the respective first regions 71, at least one of the elastic waist lines or threads 81 overlap the front or rear flap 46, 47 of the absorbent structure 41. With said harmonization, the front and rear extreme flaps 46, 47 can be placed in next contact with the user's skin and thus prevent body waste, such as urine, from leaking beyond the front and rear ends 40a, 40b.
    [00043] With respect to the second regions 72, their clamping force may be set to be greater than in the first regions 71 to ensure that the front and rear waist members 20, 30 are placed in close contact with the body of user. Despite the high clamping force, at least in the areas of the second regions 72 overlapping the absorbent structure 41, the folds formed by the front and rear sheets 24, 25, 34, 35 should not come into direct contact with the user's skin in relation to the structure absorbent 41 be provided on these front and rear sheets 24, 25, 34, 35. This way it will be possible to prevent impressions from being left on the user's skin and relieve the uncomfortable skin irritation due to the folds. In addition, the second regions 72 include non-elastic zones 72a serving to restrict the creation of folds in those non-elastic zones 72a.
    [00044] The present invention can be implemented in the ideal diaper 10 particularly for babies, characterized in that the size of the diaper 10 in the longitudinal direction Y is relatively small. To ensure that the amount of body waste absorbed as urine is not significantly affected even when diaper 10 is sized to be relatively short in the longitudinal Y direction, it will be desirable to ensure a sufficiently large size of the absorbent structure. As a consequence, an area radius (proportion) of the absorbent structure 41 for the diaper 10 will be increased and approximately from 70 to 90% of the dimension in the longitudinal Y direction of the front and rear waist regions 11,12 will be occupied by the absorbent structure 41 Generally, the stiffness of the absorbent structure 41 is relatively high and it will be more difficult to extend the diaper 10 in the X-cross direction and to wear the diaper on the user's body when the radius of the area of the absorbent structure 41 for the diaper 10 increases. However, according to the present configuration, the clamping force of the first regions 71 extended in the vicinity of the controlled waist opening to be relatively low facilitates the diaper 10 to be widened in the transversal direction X and thus to wear the diaper 10 on the user, particularly on a baby lying face up.
    [00045] As long as the dimension of the first region 71 in the longitudinal direction Y is established at approximately 23 mm according to the present configuration, the dimension of the first region 71 will not be limited to this value and it will still be possible to establish this dimension in a range of approximately 15 to 35 mm. Similarly, it will be possible to establish the dimension of the second region 72 in an approximate range of 55 to 120 mm.
    [00046] The size of the diaper 10 according to the present invention measured in the longitudinal direction Y is in a range of approximately 400 to 520 mm, preferably in an approximate range of 410 to 450 mm and 415 mm according to the present configuration . Likewise, the dimension of the limb between legs 40 as measured in the longitudinal direction Y is in the range of approximately 350 to 450 mm, preferably in a range of approximately 370 to 380 mm and approximately 375 mm in the present configuration. The dimension of the front waist member defining the front waist region 11 as measured in the longitudinal direction Y is in the range of approximately 80 to 130 mm, preferably between 85 and 125 mm and more preferably 90 mm according to the present configuration. The dimension of the rear waist member 30 defining the rear waist region 12 as measured in the longitudinal direction Y is in the range 150 to 190 mm, preferably 155 to 185 mm, and approximately 155 mm for the present configuration.
    [00047] While two or more elastic threads or threads are used to elasticize the front and rear waist members 20, 30 in the X cross direction according to the present configuration, the means used to elasticize these waist members 20, 30 will not be limited to these elastic threads and threads and it is also possible to use various types of elastic members such as elastic sheets or strip-like elastic members. Likewise, several types of elastic members may be used as a separating elastic member 51 and the elastic member with barrier 61. While the core 42 having the smaller cross-sectional dimension X in the middle section, the front and rear sections are used accordingly. with the present configuration, it will also be possible to use the core 42 having a uniform dimension in the transversal direction X. (Second Configuration)
    [00048] Figure 6 illustrates a second configuration of the present invention characterized by the provision of third regions 74 extended adjacent to the respective second regions 72 on the side of the region between legs. The characteristics other than these, are similar to those of the first configuration. Similar characteristics are designated by numerical references similar to those used in the first configuration and will not be repeatedly described in detail.
    [00049] The front and rear waist regions 11, 12 respectively comprise the first regions 71, the second regions 72 and the third regions 74. The second regions 72 and the third regions 73 are respectively connected by imaginary lines 76. According to in the present configuration, the second regions 72 respectively have a dimension in the longitudinal Y direction of approximately 44 mm and the third regions of respectively have a dimension in the longitudinal Y direction of approximately 27.5 mm. However, the present invention will not be limited to those values. Specifically, the dimension of the second regions 72 can be appropriately selected in a range of approximately 27 to 50 mm and the third regions can be appropriately selected in an approximate range of 25 to 36 mm. It should be understood here that the dimension of the respective first regions 71 in the longitudinal direction Y will be the same as that of the first configuration.
    [00050] The values of the clamping force provided by the first and second regions 71.72 are the same as those having been described with respect to the first configuration. The clamping force of the respective third regions 74 can be selected in a range of approximately 0.16 to 0.28 and set at approximately 0.18 in accordance with the present configuration. The method of measuring the clamping force is the same as that used for the first configuration. The clamping force of the respective second regions 72 may be greater than that of the respective third regions 74 by approximately 20 to 50% and, according to the present configuration, this clamping force is established to be greater than that of the respective third regions 74 approximately 40%.
    [00051] The third regions 74 formed adjacent to the respective second regions 71 on the side of the region between legs 13 contribute to the improvement in sensation when wearing the diaper 10, The third regions 74 are adapted to come into contact with the inguinal region of the user and , if the clamping force of these third regions 74 is extremely high, particularly the front and rear leaves 24, 15 of the front waist member 20, it should dig the inguinal region of the user. However, by controlling the clamping force of these third regions 74 to be relatively low, cavity in the inguinal region may be restricted. On the other hand, the second regions 72 having relatively high clamping force ensure these regions in close contact with the user's body. In this way, the convenience, as well as the leakage barrier function, should not be impaired. The clamping force of the respective second regions 72 can be set to be greater than that of the second regions 74 by approximately 20 to 50% to ensure that the second regions 72 are maintained in close contact with the user's body and at the same time the third regions regions being prevented from poking the user's inguinal region.
    [00052] As long as the clamping force of the first region and the clamping force of the second region on the front waist member 20 are set to be the same as that of the rear waist member 30 according to both the first configuration and the second configuration, it will be possible differentiate the clamping force of the first region and the clamping force of the second region on the front waist member 20 from that of the rear waist member 30, For example, the clamping force of the first region on the rear waist member 30 may be established to be lower than that on the front waist member 20 to facilitate widening of the rear waist region 12 in the X cross direction. This makes it easier to wear the diaper particularly with the user lying face up. While the distance from the respective waist ends 22, 32 to the front and rear ends 42a, 42b of the core 42 are the same according to the first and second configurations, these distances can also be differentiated.
