Description

  The present invention relates to an absorbent article.

  Absorbent articles such as disposable diapers are usually manufactured as a combination of an outer layer body and an absorbent main body. The outer layer body is generally formed by laminating an inner exterior member and an outer exterior member. For such absorbent articles, the user has been required to have a feeling of use that is not different from that of underwear. Under such circumstances, attempts have been made to improve the shape and structure of members of the outer layer body.

  In recent years, the performance of absorbent articles such as disposable diapers has improved year by year, and even when urinating, the feeling of wearing such as the touch does not deteriorate, so the wearer does not complain of discomfort, and the caregiver is not much concerned about replacing the absorbent article. In some cases, it is no longer available. In such a case, the absorbent article remains wet, which often leads to wearer discomfort and skin problems.

  The rash caused by wearing the absorbent article is caused by the skin swell in the absorbent article in a hot and humid state, and also caused by reaction with excrement, friction caused by the cloth or paper of the absorbent article itself, and Some come from bacteria. The preventive method is to keep the skin dry, do not irritate the skin, and keep it clean.

  From such a point of view, an absorbent article is desired in which a slit is provided on the surface of the absorbent article and ventilation is secured by the slit to reduce the humidity and temperature inside the absorbent article.

  For example, Patent Document 1 teaches a pants-type diaper 10 in which a slit portion 38 is formed. As shown in FIG. 18, the pants-type diaper 10 is formed using an exterior body 11. The exterior body 11 is configured by laminating and bonding an outer layer material 33 (first sheet material) on the non-skin contact surface side and an inner layer material 31 (second sheet material) on the skin contact surface side. A plurality of horizontally long slit portions 38 are partially formed in the outer layer material 33 along the width direction (X direction) of the pants-type diaper 10. A plurality of slit portions 38 are arranged in the body height direction (Y direction) to form a slit region 71. The slit portion 38 is formed as a portion obtained by finely cutting the first sheet material forming the outer layer material 33. The slit portion 38 is formed on the exterior member 33 at a position where the distances from the two elastic bodies 35 adjacent in the Y direction are equal.

JP, 2014-221112, A

  However, in the pants-type diaper 10 of Patent Document 1, the slit portion 38 is located in the middle of the elastic member 35 adjacent in the vertical direction. Therefore, when the tension | tensile_strength by an elastic member is received by wear etc., the upper and lower edges of a slit shrink | contract similarly, and the opening required for ventilation | gas_flowing is not fully opened.

  In order to solve the above problems, the present invention is directed to using an outer layer body in which the distance between the elastic member adjacent on the upper side and the slit is different from the distance between the elastic member adjacent on the lower side and the slit. This is an absorbent article.

That is, the main invention for achieving the above object is:
An absorbent article having a longitudinal direction, a transverse direction and a thickness direction orthogonal to each other,

=== First Embodiment ===
FIG. 1 is a perspective view of an absorbent article 100 according to the present invention, such as a three-piece type disposable diaper.

  Moreover, FIG. 2 is the schematic plan view which looked at the absorbent article 100 of the expansion | deployment state from the skin side.

  As shown in FIGS. 1 and 2, the absorbent article 100 has a vertical direction, a horizontal direction, and a thickness direction that are orthogonal to each other. The absorbent article 100 includes an absorbent main body 102 that covers the crotch of the wearer and absorbs fluid such as excrement, an abdominal exterior member 104 that covers the abdomen of the wearer, and a back that covers the back of the wearer. Side exterior member 106.

  The absorbent main body 102 is disposed such that its longitudinal direction is along the longitudinal direction, and the abdominal exterior member 104 is disposed such that its longitudinal direction is along the lateral direction, and one end in the longitudinal direction of the absorbent main body 102 is disposed. It is overlapped and fixed to the part from the non-skin side in the thickness direction. The back side exterior member 106 is disposed as a separate member having a larger area than the abdominal side exterior member 104 so that its longitudinal direction is along the lateral direction, and is thick at the other end in the longitudinal direction of the absorbent main body 102. It is overlapped and fixed from the non-skin side in the vertical direction.

2, the abdominal exterior member 104 and the back exterior member 106 are arranged in parallel with a space between each other, and the absorbent main body therebetween. 102, the end portions 102ea and 102eb in the longitudinal direction of the absorbent main body 102 are joined and fixed to the nearest ventral-side exterior member 104 and back-side exterior member 106, respectively, and the external shape is abbreviated in plan view. It has an H shape. Then, from this state, the absorbent main body 102 is folded in half with the substantially central portion 102ax in the longitudinal direction as the folding position, and the abdominal exterior member 104 and the back exterior member 106 that face each other in this folded state However, when connected at the portions 104e and 106e (lateral end portions 104e and 106e) that should contact the wearer's flank, the abdominal exterior member 104 and the back exterior member 106 are connected in a ring shape. Thus, the absorbent article 100 in a worn state in which the waist opening AP _wc and the pair of leg openings AP _tc as shown in FIG. 1 are formed is obtained.

  Various connection structures can be adopted as the connection structure between the abdominal exterior member 104 and the back exterior member 106. For example, if a non-removable connection structure such as welding is used, a pants-type absorbent article 100 can be obtained, and if a detachable connection structure such as a fastening tape member (not shown) is used, an open-type absorbent article 100 is provided. Can be. In this example, the former connection structure is used, and thereby the absorbent article 100 is a pants-type.

  As shown in FIGS. 2 and 3B, the absorbent main body 102 includes an absorbent core 108 obtained by molding liquid absorbent fibers such as pulp fibers into a predetermined shape such as a substantially hourglass shape in plan view, and the absorbent core 108. A top sheet member 110 that covers the skin from the skin side, and a back sheet member 112 that covers the absorbent core 108 from the non-skin side and forms the exterior of the absorbent main body 102. The absorbent core 108 may contain liquid absorbent granules such as a superabsorbent polymer, or may contain liquid absorbent materials other than liquid absorbent fibers and liquid absorbent granules. The absorbent core 108 may be covered with a liquid permeable sheet such as tissue paper (not shown).

  The top sheet member 110 is a liquid-permeable nonwoven fabric having a larger planar size than the absorbent core 108. The back sheet member 112 is also a sheet having a larger plane size than the absorbent core 108. For example, a two-layer in which a liquid-impermeable leak-proof sheet 112a such as polyethylene or polypropylene and an exterior sheet 112b such as a nonwoven fabric are bonded together. The sheet member 112 having a structure can be used. In a state where the absorbent core 108 is sandwiched between the back sheet member 112 and the top sheet member 110, the leakproof sheet 112a and the top sheet of the back sheet member 112 are portions that protrude outward from the four sides of the absorbent core 108. The member 110 is bonded in a frame shape, and thereby the absorbent main body 102 is formed.

As shown in FIGS. 1, 2, and 3B, the three-dimensional gather LCG and the leg gathers LG may be formed by the exterior sheet 112b. The three-dimensional gather LCG refers to leakage prevention wall portions LCG that are provided upright at the respective lateral end portions of the top sheet member 110, and the leg-hole gathers LG are formed in the leg-hole openings AP _tc of the absorbent article 100. The elastic part LG formed is pointed out. The dimension of the exterior sheet 112b in the horizontal direction is sufficiently larger than that of the leak-proof sheet 112a, that is, the exterior sheet 112b protrudes from the both sides of the leak-proof sheet 112a in the lateral direction. The protruding portion 112bf is folded back to the center in the lateral direction with the position forming the lateral end portion 102es of the absorbent main body 102 as the folded position, and thread rubber or the like is formed along the longitudinal direction in the vicinity of the folded position. The elastic member 114 is fixed in an extended state in the vertical direction, and a leg-hole gather LG is formed. The folded portion 112bg further extends toward the center in the lateral direction, and is joined to the lateral end at a position covering the lateral end of the topsheet member 110. The lateral end bonded portion of the functions as a base end portion LCG _b of standing gathers LCG, surface sheet member further lateral distal end portion than the proximal end portion LCG _b as a free end portion LCG _f 110 can stand up. An elastic member 116 such as a rubber thread is fixed in the longitudinal direction in the longitudinal direction at the distal end of the free end portion LCG _f . Therefore, the elastic main body 102 is bent in the vertical direction so that the topsheet member 110 side is the inner peripheral side by the vertical contraction of the elastic member 116. The end portion LCG _f contracts in the vertical direction and rises from the surface sheet member 110, whereby the free end portion LCG _f functions as a three-dimensional gather LCG.

  A liquid permeable sheet such as tissue paper may be interposed as a second sheet between the top sheet member 110 and the absorbent core 108 or between the back sheet member 112 and the absorbent core 108.

  Each of the ventral exterior member 104 and the back exterior member 106 can be formed by using a sheet member having a substantially rectangular shape in plan view made of a flexible sheet such as a nonwoven fabric. As shown in FIGS. 3A and 3B, the non-skin-side non-skin side sheet 118 and the non-skin-side sheet 120 are joined together to form the abdominal-side exterior member 104 and the back-side exterior member 106. The non-skin side sheet 118 and the skin side sheet 120 do not have to be the same size as each other. For example, the non-skin side sheet 118 and the skin side sheet 120 may be configured as shown in FIG. 4 showing a VI-VI cross-sectional view in FIG. . That is, the sizes in the vertical direction may be different from each other so that the non-skin side sheet 118 positioned on the non-skin side in the thickness direction protrudes from the skin side sheet 120 to the end side in the vertical direction. In this case, as shown in FIG. 4, in the non-skin side sheet 118, a portion 118 f that protrudes from the skin side sheet 120 in the vertical direction is a position in the vicinity of the vertical edge of the skin side sheet 120. Is folded back to the center in the vertical direction. The folded portion 118g is overlapped and joined to the skin side sheet 120. At the time of folding, a part of the longitudinal ends 102ea and 102eb of the absorbent main body 102 may be covered from the skin side of the absorbent main body 102 with the folded portion 118g.

  As shown in FIGS. 1 and 2, the abdominal exterior member 104 and the back exterior member 106 have inner overlapping regions 132be and 132re that overlap with the absorbent main body 102 in the longitudinal direction and the lateral direction, respectively. Armpit regions 134be and 134re that overlap in the vertical direction and do not overlap in the horizontal direction, armpit regions 136be and 136re that do not overlap in the vertical direction and do not overlap in the horizontal direction, and the absorbent main body 102 And upper inner regions 138be and 138re that do not overlap in the vertical direction but overlap in the horizontal direction.

The abdominal exterior member 104 and the back exterior member 106 are inner overlapping regions 132be and 132re, respectively, while covering the longitudinal ends 102ea and 102eb of the absorbent main body 102 from the non-skin side of the absorbent main body 102, respectively. Inner overlapping regions 132be and 132re of the abdominal exterior member 104 and the back exterior member 106 are overlapped and joined to the respective end portions 102ea and 102eb.
The superposition of the absorbent main body 102 on the inner overlapping regions 132be and 132re of the abdominal exterior member 104 and the back exterior member 106 is performed without overlapping the absorbent main body 102 on the inner upper regions 138be and 138re. Thus, the inner upper regions 138be and 138re in the abdominal exterior member 104 and the back exterior member 106 become strip-shaped portions that do not overlap with the absorbent main body 102 in the longitudinal direction over the entire length in the lateral direction. These inner upper regions 138be and 138re become a part constituting the waistline opening AP _wc of the absorbent article 100. In these inner upper regions 138be and 138re, the elastic member 140 is arranged in the lateral direction in the inner upper regions 138be and 138re. Are provided continuously over substantially the entire length. Further, regarding the longitudinal sizes L _be and L _re of the inner upper regions 138be and 138re where the absorbent main body 102 does not overlap, the back side exterior member 106 is made larger than the ventral side exterior member 104 (L _re > L _be ), and as a whole, the absorbent main body 102 is disposed more biased toward the ventral-side exterior member 104 than the back-side exterior member 106. Thereby, the smooth absorbability of fluids, such as excrement, is ensured. Alternatively, the magnitude relationship between the magnitudes L _be and L _re may be reversed (L _re <L _be ), or the magnitudes L _be and L _re are equal to each other (L _re = L _be ). May be.

  In the absorbent article 100 according to the present invention, a plurality of elastic members 140 such as thread rubber are provided between the non-skin side sheet 118 and the skin side sheet 120 along the lateral direction. The elastic member 140 is a non-skin side in a state where it is stretched in a lateral direction by an adhesive region formed by adhering (applying) an adhesive such as a hot melt adhesive with a predetermined basis weight (weight per unit area). It is fixed to one or both of the sheet 118 and the skin side sheet 120. The formation of the adhesive region may be performed by attaching an adhesive to the non-skin side sheet 118 and the skin side sheet 120, or may be performed by attaching an adhesive to the elastic member 140 side. May be done by both.

  As shown in FIG. 2, in the abdominal exterior member 104 and the back exterior member 106, the pair of inner adhesive regions 142 have both lateral directions with respect to the longitudinal ends 102 ea and 102 eb of the absorbent main body 102. It is formed so as to overlap with the elastic member 140 on the inner side. In the inner adhesive region 142, the adhesive is applied to the entire region using a coating means such as spiral coating, control seam coating, or full surface coating by a slot coater.

  In the absorbent article 100 according to the present invention, at least a part of the elastic member 140 is cut to adjust the lateral contraction force.

  The elastic member 140 arranged in the laterally extended state is cut by a cutter or the like between the pair of inner adhesive regions 142, for example, at the position of the center line CL. However, the cut portion of the elastic member 140 is not limited to the position of the center line CL, and may be cut at a position deviated from the center line CL, or the elastic member 114 for the leg gathers LG and the three-dimensional gather LCG. It may be cut at a plurality of locations between the elastic members 116 for use. Further, the elastic member 140 may be cut in a plurality of cutting steps instead of being cut in a single cutting step (cutting operation). The cut elastic member 140 contracts from the cut portion to the outside in the lateral direction of the elastic member 114 for the leg gathers LG and the elastic member 116 for the three-dimensional gather LCG. Hereinafter, this operation is referred to as “cutback”.

  Of the elastic member 140, the expansion ratio of the portion disposed in the region overlapping the absorbent main body 102 (the region where the elastic member 140 is cut back) is the expansion magnification of the elastic member 140 in the other region or the other elastic member. Higher than. “Elongation magnification” refers to the degree of expansion when each elastic member is fixed to a sheet or the like in an expanded state. The higher the expansion magnification, the greater the elastic member can express a contracting force. This is because when the expansion ratio of the elastic member 140 is low, cutback may be insufficient. For example, when the expansion ratio is low, after the elastic member 140 is cut at the center line CL, the elastic member 140 does not sufficiently contract, and a part of the elastic member 140 is the elastic member 114 for the leg gathers LG and the three-dimensional gather LCG. There is a possibility that the elastic member 116 may remain inside the horizontal direction. Therefore, by making the expansion ratio of the elastic member 140 in the region overlapping with the absorbent main body 102 higher than the expansion ratio of other elastic members or the like, the contraction due to cutback is appropriately generated. Accordingly, it is possible to suppress a part of the elastic member 140 contracted in the lateral direction from remaining inside the elastic member 114 for the leg gathers LG and the elastic member 116 for the three-dimensional gather LCG in the lateral direction.

  Thus, by precisely controlling the position where the elastic member 140 is contracted and cutting it back, it is possible to adjust the tightening force around the waist with high accuracy, and the fit of the absorbent article 100 can be further improved. . Moreover, since the elastic member 114 for the leg gathers LG and the elastic member 116 for the three-dimensional gather LCG and the elastic member 140 do not intersect with each other due to the cutback, the mutual contraction force is less likely to act, and the absorbency When the article 100 is worn, the wearer can easily move the legs and the like.

  Returning to FIG. 1 and FIG. 2, in the abdominal side exterior member 104 and the back side exterior member 106 formed by laminating the non-skin side sheet 118 and the skin side sheet 120, a plurality of horizontally long absorbent articles 100 are formed. A cut 150 is formed in the armpit areas 134be and 134re and the armpit areas 136be and 136re. A plurality of the cut lines 150 are formed in a row at a predetermined interval (slit pitch) along the lateral direction of the absorbent article 100. Referring to FIG. 2, for example, in the armpit regions 134be and 134re, the length of each cut (slit length) is 3 [mm], and the slit pitch is 8 [mm], and four per row. A cut 150 is formed. In the side regions 136be and 136re, five cuts 150 having a slit length of 2 [mm] are formed for each row with a slit pitch of 8 [mm]. A plurality of the cuts 150 in one row are formed in the vertical direction at a predetermined interval according to the interval between the elastic members 140 in the vertical direction. The cut 150 is a portion obtained by finely cutting at least one of the non-skin side sheet 118 and the skin side sheet 120. The linear cut 150 is preferably 5 mm to 15 mm in length. The cut 150 can be easily recognized by setting the slit length to 5 [mm] or more, and by setting the slit length to 15 [mm] or less, the material can be prevented from rolling up. The cut 150 may be a linear cut or may be a notched portion with a width. Considering the strength of the member, it is preferable to have a linear cut. The cut 150 may be formed in at least one of the abdominal exterior member 104 and the back exterior member 106, and is similarly formed in the abdominal exterior member 104 and the back exterior member 106. There may be. Further, the cut 150 may be formed on at least one of the non-skin side sheet 118 and the skin side sheet 120, and is similarly formed on the non-skin side sheet 118 and the skin side sheet 120. There may be.

As shown in FIG. 2, the underarm regions 134be and 134re and the underarm regions 136be and 136re, which are cut, have a width W in the lateral direction and a width M in the lateral direction. The inner overlapping regions 132be and 132re and the inner upper regions 138be and 138re are located on both sides. Among the above-mentioned regions having a width W, the side outside beside the joint base portion near the side seal region located within a distance W ₂ from each end 104e and 106e in the lateral direction of the ventral side outer member 104 and the back side outer member 106 A cut 150 is formed in the inner region having the width of W ₁ excluding the portion W ₂ (hereinafter, this region is referred to as “both side slit region SSA”). Further, a side region 136be and 136Re, and the inner upper region 138be and 138Re, to form a waist-opening _{AP wc} of the absorbent article 100, the longitudinal direction of each end of the ventral side outer member 104 and the back side outer member 106 from parts, in the longitudinal direction has a length _{H 1,} and the underarm areas 134be and 134Re, and the inner overlapping area 132be and 132Re, to form a leg opening _{AP tc} of the absorbent article 100, the ventral side outer from each end of the longitudinal member 104 and the back side outer member 106 has a length H ₂ in the vertical direction. That is, the length H in the vertical direction of the ventral exterior member 104 and the back exterior member 106 is represented by H = H ₁ + H ₂ . From each end of the inner overlap area 132be and 132re leg-openings _{AP tc} side of the portion having a length _{H 2} in the vertical direction, the portions that are within a distance _{H 20} from the end of the The cutback process is performed, and the elastic member 140 does not exist in the part of the absorbent core 108. Of underarm area 134be and 134Re, to form a leg opening _{AP tc} of the absorbent article 100, the longitudinal portion which is within the distance _{H 20} from each end of the ventral side outer member 104 and the back side outer member 106 Is formed with a long cut 150. The remaining of the underarm area 134be and 134Re, the longitudinally and has a length _{H 21} moiety, short cut 150 is formed. The vertical lengths H ₂ of the armpit regions 134be and 134re and the inner overlap regions 132be and 132re are represented by H ₂ = H ₂₀ + H ₂₁ . Short cuts 150 are formed in the side regions 136be and 136re.

The inner overlapping regions 132be and 132re and the inner upper regions 138be and 138re having a width M in the horizontal direction are a region where the cut 150 is not formed (hereinafter, this region is referred to as a “non-slit region NSA”). It has become. Further, the side region outer portion W _{2 in} the vicinity of the side seal region is a non-slit region over the entire length H of the abdominal exterior member 104 and the back exterior member 106.

  As described above, the slit regions SSA on both sides of the abdominal exterior member 104 and the back exterior member 106 are arranged in the lateral width direction at intervals with the non-slit region NSA interposed therebetween. In the non-slit region NSA, the abdominal exterior member 104 or the back exterior member 106 and the absorbent main body 102 overlap in the longitudinal direction and the lateral direction. It will be the part you have. The lateral length M of the non-slit area NSA of the ventral exterior member 104 and the back exterior member 106 takes into account the action of the both-side slit area SSA and the bonding strength between the non-skin side sheet 118 and the skin side sheet 120. Can be set as appropriate.

  In the laminated region of the non-skin side sheet 118 and the skin side sheet 120, both the sheet members are joined and integrated, and has stretchability in the waistline direction of the absorbent article 100, that is, in the lateral direction. Both side slit regions SSA of the non-skin side sheet 118 are joined to the inner layer material 31 and have elasticity. In the both-side slit area SSA, the non-skin side sheet 118 and the skin side sheet 120 are joined in a planar shape over the length H in the longitudinal direction and have elasticity. This stretchability is further enhanced by interposing the elastic member 140 between the non-skin side sheet 118 and the skin side sheet 120. In this case, the elastic member 140 is sandwiched between the non-skin-side sheet 118 and the skin-side sheet 120 in an expanded state, and thereby has elasticity. Alternatively, the non-skin side sheet 118 and / or the skin side sheet 120 may be configured by using a stretchable material.

  In the both-side slit region SSA, the gap between the two edges constituting the cut 150 is widened by the lateral contraction of the stretchable ventral exterior member 104 and the backside exterior member 106, and the ventral exterior member 104 and the backside exterior It becomes a vent of the member 106. In addition, when the wearer extends or contracts the abdominal exterior member 104 and the back exterior member 106 due to movement of the body after the absorbent article 100 is attached, the vents open and close in accordance with the movement, and the interior of the absorbent article 100 Promotes moisture discharge and further enhances air permeability. Further, since there are a plurality of cut lines 150, the both-side slit area SSA of the non-skin-side sheet 118 is more easily deformed than the non-slit area NSA and is excellent in flexibility. Further, due to the stretchability, the individual cuts 150 are twisted to make fine wrinkles, and the waist area becomes soft.

A plurality of elastic members 140 are arranged between the non-skin-side sheet 118 and the skin-side sheet 120 in a laterally extended state, spaced apart in the vertical direction, avoiding the cuts 150 formed in a row, and fixed by bonding. Has been. That is, the elastic member 140 is firmly sandwiched and bonded and fixed to the non-skin side sheet 118 and the skin side sheet 120 without being exposed to the outside from the cut 150. As a result, the elastic member 140 provides stretchability in the waist direction, that is, in the lateral direction, with the non-skin side sheet 118 and the skin side sheet 120 forming the abdominal side exterior member 104 and the back side exterior member 106 as an integral body. Elastic member 140, using a hot melt adhesive as described above, not only the joint on both sides slit area SSA, the inner overlap area 132be and 132re and the side outside lateral portion _{W 2} non-skin side sheet 118 and the skin side It is preferable that the sheet 120 is continuously joined in a planar shape. Thereby, not only hot melt adhesion applied to the elastic member 140 itself but also the sheet surfaces of the non-skin-side sheet 118 and the skin-side sheet 120 can be used to prevent the rubber from coming off.

  The vertical interval between the row-shaped cut lines 150 formed at intervals in the horizontal direction may vary depending on the position in the vertical direction of the absorbent article 100, for example. It is preferable that the vertical intervals of the members 140 are different depending on the positions in the vertical direction, and the elastic members 140 are arranged one by one between two rows of cuts 150 adjacent in the vertical direction. When the pitch of the elastic member 140 is different depending on the position in the vertical direction, the interval between the cuts 150 adjacent in the vertical direction is different accordingly, and there is one between the two cuts 150 adjacent in the vertical direction. By arranging the elastic members 140 one by one, the material strength can be increased, and each cut 150 can be reliably opened.

  Here, the wearer wearing the absorbent article 100 generally tends to sweat more on the back side than on the abdomen side. Therefore, it is desirable to make the density of the cuts 150 in the backside exterior member 106 larger than the density of the cuts 150 in the ventral side exterior member 104. In addition, since the materials overlap in the thickness direction in the inner overlapping regions 132be and 132re, the region composed of the armpit regions 134be and 134re overlapping the inner overlapping region in the vertical direction and the inner overlapping regions 132be and 132re is In addition, the absorbent article 100 has a large rigidity against a stress that attempts to shear the absorbent article 100 along the lateral direction. Accordingly, it is desirable to make the density of the cuts in the armpit regions 134be and 134re larger than the density of the cuts in the inner upper regions 138be and 138re and the armpit regions 136be and 136re.

Therefore, the plurality of cuts 150 formed as shown in FIG. 2 are the sum of the lengths of the cuts 150 in the side region 136be of the ventral-side exterior member 104 being L (be) bus , and the cuts 150 in the inner upper region 138be. of the total length L (be) mus, when the total length of the slit 150 in the underarm area 134be and L (be) bls, {( L (be) bus + L (be) mus) / H 1} satisfy <{L (be) bls / H 2}. That is, in the ventral exterior member 104, the total length of the cuts 150 per unit length in the vertical direction of the armpit region 136be and the inner upper region 138be is the length of the cut 150 per unit length of the armpit region 134be. Less than the sum of

Further, in the plurality of cuts 150 formed as shown in FIG. 2, the total length of the cuts 150 in the side region 136re of the backside exterior member 106 is L (re) bus , and the cuts 150 in the inner upper region 138re. length total L (re) mus of, when the total length of the slit 150 in the underarm area 134re and L (re) bls, {( L (re) bus + L (re) mus) / H 1} satisfy <{L (re) bls / H 2}. That is, in the backside exterior member 106, the total length of the cuts 150 per unit length in the vertical direction of the armpit region 136re and the inner upper region 138re is the length of the cut 150 per unit length of the armpit region 134re. Less than the sum of

  By forming the cut 150 as described above, the region overlapping with the absorbent main body 102 in the longitudinal direction has a large rigidity against the force to tear the absorbent article 100 along the lateral direction. By forming a large number of cuts 150 in the region overlapping with the absorbent main body 102 in the vertical direction, air passage is ensured, and by forming a few cuts 150 in the region not overlapping with the absorbent main body 102 in the vertical direction, ventilation is achieved. The material strength can be ensured while ensuring.

Further, in the above case, the plurality of cuts 150 formed as shown in FIG. 2 are {(L ^(be) _bus + L ^(re) _bus ) / H ₁ } <{(L ^(be) _bls + L ^{( re)} _bls ) / H ₂ }. That is, the total length of the linear breaks 150 in the side regions 136be and 136re that do not overlap with the absorbent main body 102 in the vertical direction and does not overlap with the absorbent main body 102 in the horizontal direction is defined as the side region 136be and divided by the vertical length H ₁ of 136re is overlapped with the absorbent body 102 in the longitudinal direction of the ventral side outer member 104 and the back side outer member 106, and does not overlap with the absorbent body 102 in the lateral direction the total length of linear cuts 150 in the underarm area 134be and 134Re, smaller than a value obtained by dividing the vertical length _{H 2} of the underarm area 134be and 134Re.

  Similarly to the above, the region overlapping with the absorbent main body 102 in the vertical direction has a large rigidity against the force of tearing the absorbent article 100 along the horizontal direction. By forming a large number of cuts 150 in a region overlapping with the main body 102, the ventilation is ensured, and by forming a few cuts 150 in a region not overlapping with the absorbent main body 102 in the vertical direction, the material strength is ensured while ensuring the ventilation. This is because it can be secured.

The plurality of cuts 150 formed as shown in FIG. 2 are: L ^(be) is the total length of the cuts 150 in the ventral exterior member 104, and L is the total length of the cuts 150 in the backside exterior member 106. ^{Assuming (re)} , L ^(be) <L ^(re) is satisfied. By forming the cut line 150 in this way, the wearer of the absorbent article 100 forms more cut lines 150 on the back side where the wearer can easily perspire to ensure ventilation, thereby improving comfort during wearing. Can do.

Further, the cut 150 may not be formed in the inner upper region 138be of the ventral exterior member 104. The portion of the abdominal exterior member 104 between the absorbent main body 102 of the absorbent article 100 and the waistline opening AP _wc , in particular, the inner upper region 138be is laterally moved when the wearer pulls up the absorbent article 100. It is a part that is easy to break along. The same applies to the backside exterior member 106, but the wearer of the absorbent article 100 is more likely to sweat on the back side, so the backside exterior member 106 portion needs to ensure air permeability, When the wearer turns his back and leans forward, the wearer can move more easily if a cut is formed in the dorsal exterior member 106. Therefore, by not forming the cut 150 in the inner upper region 138be of the abdominal exterior member 104, the possibility of breakage can be reduced, and the material strength can be ensured. Furthermore, it is also possible not to form the cut 150 in the inner upper region 138be and the armpit region 136be of the abdominal exterior member 104. Similarly to the above, by not forming a cut in the inner upper region 138be and the side region 136be of the abdominal exterior member 104, the possibility of breakage can be reduced and the material strength can be ensured.

  By changing the length, interval, and number of the cuts 150, various ways of forming the cuts 150 are possible.

  FIG. 5 is a diagram illustrating another example of how to form the cuts 150 in the ventral exterior member 104 and the back exterior member 106.

  In FIG. 5, a plurality of cuts 150 are formed only in the armpit regions 134be and 134re of the abdominal exterior member 104 and the dorsal exterior member 106, and in the inner upper regions 138be and 138re and the armpit regions 136be and 136re, Not formed. In each row along the lateral direction of the absorbent article 100, four cuts 150 are formed on one side. The length of the cut is 3 [mm], and four cuts 150 are formed at intervals of 8 [mm], 12 [mm], and 8 [mm], respectively.

  When a plurality of cuts 150 are formed as shown in FIG. 5, the total length of the cuts 150 per unit length in the vertical direction of the armpit region 136be and the inner upper region 138be in the ventral exterior member 104 is This is smaller than the total length of the cuts 150 per unit length of the lower region 134be.

  Further, when a plurality of cuts 150 are formed as shown in FIG. 5, the total length of the cuts 150 per unit length in the vertical direction of the armpit region 136re and the inner upper region 138re in the backside exterior member 106 is This is smaller than the sum of the lengths of the cuts 150 per unit length of the armpit region 134re.

Further, when a plurality of cuts 150 are formed as shown in FIG. 5, linear shapes in the side regions 136be and 136re that do not overlap with the absorbent main body 102 in the vertical direction and do not overlap with the absorbent main body 102 in the horizontal direction. of the total length of the cut 150, aside region 136be and divided by the vertical length _{H 1} of 136re includes an absorbent body 102 in the longitudinal direction of the ventral side outer member 104 and the back side outer member 106 overlapping, and a total length of linear cuts 150 in the underarm area 134be and 134re that does not overlap with the absorbent body 102 in the lateral direction, longitudinal underarm area 134be and 134re length _{H 2} removal It becomes smaller than the value.

  FIG. 6 is a view showing still another example of how to form the cut 150 in the ventral exterior member 104 and the back exterior member 106.

In FIG. 6, a plurality of cuts 150 are formed only in the armpit regions 134be and 134re of the abdominal exterior member 104 and the dorsal exterior member 106, and the inner upper regions 138be and 138re and the armpit regions 136be and 136re Not formed. Each of the cuts 150 formed in the ventral exterior member 104 and the back exterior member 106 has a length of 3 [mm]. In the ventral-side exterior member 104, the plurality of gaps 150 are formed at lateral positions closer to the absorbent main body 102 as the vertical position of the row of cut lines 150 extending in the lateral direction approaches the leg periphery opening _APtc . The cut 150 of the backside exterior member 106 is formed in the same manner as in FIG. The total number of cuts 150 in the ventral exterior member 104 is 36, and the total number of cuts 150 in the backside exterior member 106 is 48.

  Therefore, when a plurality of cuts 150 are formed as shown in FIG. 6, the total length of the cuts 150 per unit length in the vertical direction of the side region 136be and the inner upper region 138be in the ventral exterior member 104 is This is smaller than the total length of the cuts 150 per unit length of the armpit region 134be.

  Further, when a plurality of cuts 150 are formed as shown in FIG. 6, the total length of the cuts 150 per unit length in the vertical direction of the side region 136re and the inner upper region 138re in the backside exterior member 106 is This is smaller than the sum of the lengths of the cuts 150 per unit length of the armpit region 134re.

Further, when a plurality of cuts 150 are formed as shown in FIG. 6, linear shapes in the side regions 136be and 136re that do not overlap with the absorbent main body 102 in the vertical direction and do not overlap with the absorbent main body 102 in the horizontal direction. of the total length of the cut 150, aside region 136be and divided by the vertical length _{H 1} of 136re includes an absorbent body 102 in the longitudinal direction of the ventral side outer member 104 and the back side outer member 106 overlapping, and a total length of linear cuts 150 in the underarm area 134be and 134re that does not overlap with the absorbent body 102 in the lateral direction, longitudinal underarm area 134be and 134re length _{H 2} removal It becomes smaller than the value.

In the ventral-side exterior member 104 of FIG. 6, since the cut 150 is formed closer to the center of the absorbent article 100 as the position in the vertical direction approaches the leg opening AP _tc , when the absorbent article 100 is worn, In the portion corresponding to the base of the foot, the bending rigidity in the longitudinal direction of the absorbent article 100 is lowered, and when the foot is moved, it becomes easy to bend along the shape of the groin portion. Further, since the material strength is reduced at the portion covering the groin, the abdomen exterior member 104 is easily fitted to the groin as the elastic member 140 contracts. By being easy to fit, it becomes difficult to form a space between the abdominal exterior member 104 and the wearer's abdomen, so that the air warmed by the body temperature is less likely to stagnate, and air is ventilated by the cut 150. Therefore, the air permeability is improved.

  FIG. 7 is a diagram showing still another example of how to form the cut 150 in the ventral exterior member 104 and the back exterior member 106.

  In FIG. 7, a plurality of cuts 150 are formed only in the armpit regions 134be and 134re of the abdominal exterior member 104 and the dorsal exterior member 106, and in the inner upper regions 138be and 138re and the armpit regions 136be and 136re, Not formed. In FIG. 7, the cut 150 formed in the abdominal exterior member 104 and the back exterior member 106 has a length of 3 [mm] in a region having a lateral length of 3 [mm] and a longitudinal length of 2 [mm]. ] Is formed as a multiple slit 150 having three cuts. If comprised in this way, the non-skin side sheet | seat 118 between each cut | interruption of the multiple slit 150 will become a some strip | belt-shaped part, and since each strip | belt-shaped part is twisted independently, it becomes easier to visually recognize opening.

  When a plurality of multiple slits 150 are formed as shown in FIG. 7, in the ventral exterior member 104, the total length of the cuts 150 per unit length in the vertical direction of the side region 136be and the inner upper region 138be is It becomes smaller than the sum total of the length of the cut 150 per unit length of the armpit area 134be.

  Further, when a plurality of multiple slits 150 are formed as shown in FIG. 7, the total length of the cuts 150 per unit length in the vertical direction of the side region 136 re and the inner upper region 138 re in the backside exterior member 106. Is smaller than the total length of the cuts 150 per unit length of the armpit region 134re.

Further, when a plurality of multiple slits 150 are formed as shown in FIG. 7, lines in the side regions 136be and 136re that do not overlap with the absorbent main body 102 in the vertical direction and do not overlap with the absorbent main body 102 in the horizontal direction. the total length of the shaped for cuts 150, aside region 136be and divided by the vertical length _{H 1} of 136re, the absorbent body 102 in the longitudinal direction of the ventral side outer member 104 and the back side outer member 106 It overlaps with, and the total length of the linear cuts 150 in the underarm area 134be and 134re that does not overlap with the absorbent body 102 in the lateral direction, longitudinal underarm area 134be and 134re length _{H 2} Smaller than the divided value.

  FIG. 8 is a diagram showing still another example of how to form the cut 150 in the ventral exterior member 104 and the back exterior member 106.

  In FIG. 8, a plurality of cuts 150 are formed only in the armpit regions 134be and 134re of the abdominal exterior member 104 and the dorsal exterior member 106, and in the inner upper regions 138be and 138re and the armpit regions 136be and 136re, Not formed. In the armpit regions 134be and 134re, there are two different arrangement patterns of the cuts 150 along each row of the cuts 150 that are continuous in the horizontal direction. For example, in FIG. 5, four cuts 150 having a length of 3 [mm] are formed at intervals of 8 [mm], 12 [mm], and 8 [mm], respectively. In FIG. 1, one pattern is a pattern in which only even-numbered cuts 150 are formed, and another pattern is a pattern in which only odd-numbered cuts are formed. As shown in the figure, the above one pattern and another pattern are alternately formed at different positions in the vertical direction of the armpit regions 134be and 134re.

  When a plurality of cuts 150 are formed as shown in FIG. 8, in the ventral exterior member 104, the total length of the cuts 150 per unit length in the vertical direction of the side region 136be and the inner upper region 138be is This is smaller than the total length of the cuts 150 per unit length of the lower region 134be.

  Further, when a plurality of cuts 150 are formed as shown in FIG. 8, in the backside exterior member 106, the total length of the cuts 150 per unit length in the vertical direction of the side region 136re and the inner upper region 138re is This is smaller than the sum of the lengths of the cuts 150 per unit length of the armpit region 134re.

Further, when a plurality of cuts 150 are formed as shown in FIG. 8, the linear shapes in the side regions 136be and 136re that do not overlap with the absorbent main body 102 in the vertical direction and do not overlap with the absorbent main body 102 in the horizontal direction. of the total length of the cut 150, aside region 136be and divided by the vertical length _{H 1} of 136re includes an absorbent body 102 in the longitudinal direction of the ventral side outer member 104 and the back side outer member 106 overlapping, and a total length of linear cuts 150 in the underarm area 134be and 134re that does not overlap with the absorbent body 102 in the lateral direction, longitudinal underarm area 134be and 134re length _{H 2} removal It becomes smaller than the value.

  FIG. 9 is a diagram showing still another example of how to form the cut 150 in the ventral exterior member 104 and the back exterior member 106.

  The arrangement of the cut lines 150 in FIG. 9 is obtained by replacing the cut lines 150 of the backside exterior member 106 with the multiple slits 150 in the arrangement of the cut lines 150 in FIG. Similarly to FIG. 7, also in FIG. 9, the cut 150 formed in the backside exterior member 106 has a length 3 [mm] in a region having a length 3 [mm] in the horizontal direction and a length 2 [mm] in the vertical direction. mm] is formed as a multiple slit 150.

When the total length of the slits 150 constituting the slit 150 is L ^(re) , L ^(be) <L ^(re) is satisfied.

  Furthermore, when a plurality of cuts 150 are formed as shown in FIG. 9, the total length of the cuts 150 per unit length in the vertical direction of the armpit region 136be and the inner upper region 138be in the ventral exterior member 104 is This is smaller than the total length of the cuts 150 per unit length of the armpit region 134be.

  In addition, when a plurality of cuts 150 and multiple slits 150 are formed as shown in FIG. 9, multiple slits 150 per unit length in the vertical direction of the side region 136re and the inner upper region 138re are formed on the backside exterior member 106. The total length of the cuts 150 to be configured is smaller than the total length of the cuts 150 that form the multiple slits 150 per unit length of the armpit region 134re.

Furthermore, when a plurality of cuts 150 and multiple slits 150 are formed as shown in FIG. 9, the side regions 136be that do not overlap with the absorbent main body 102 in the vertical direction and do not overlap with the absorbent main body 102 in the horizontal direction, and value the total length of the linear cuts 150 in 136Re, divided by the vertical length _{H 1} aside region 136be and 136Re are absorbed in the longitudinal direction of the ventral side outer member 104 and the back side outer member 106 The total length of the linear breaks 150 in the underarm regions 134be and 134re that overlap the sex main body 102 and does not overlap the absorbent main body 102 in the lateral direction is the vertical length of the underarm regions 134be and 134re. It is smaller than a value obtained by dividing H _2.

  The arrangement of cuts in FIG. 10 is the same as the arrangement of cuts in FIG. 5, and the cuts 150 are each formed in an X shape. Further, the arrangement of the cuts in FIG. 11 is the same as the arrangement of the cuts in FIG.

  The operation and effect of the arrangement of the cuts 150 described in FIGS. 10 and 11 are the same as the arrangement of the cuts 150 described in FIG.

  FIG. 12 is a diagram showing a positional relationship between two elastic members 140 adjacent to each other in the longitudinal direction and the cut 150 in the absorbent article 100 according to the present invention.

  If the arrangement of the elastic member 140 and the plurality of cuts 150 is devised, the air permeability can be further improved by the interaction between the elastic member 140 and the cuts 150.

As described above, the cut 150 is formed in at least one of the non-skin side sheet 118 and the skin side sheet 120, and the elastic member 140 avoids the cut 150 formed in a row in the lateral direction, and the non-skin side sheet 118. A plurality of sheets are arranged between the skin side sheet 120 and the skin side sheet 120 in an extended state in the horizontal direction with an interval in the vertical direction. 12, the distance between the elastic members 140 ₀ and 140 ₁ adjacent to each other in the longitudinal direction (yarn Gomupitchi) is d, the distance between the lower side of the elastic member 140 ₀ and cut 150 is _{d l,} the distance between the cut 150 and the upper elastic member 140 ₁ is _{d u.} The relationship d _l + d _u = d is established, and d _l = d _u in the prior art, but d _l <d _{u in} FIG.

  Here, it is assumed that the non-skin side sheet 118 and / or the skin side sheet 120 in which the cut 150 is formed is an isotropic material.

In the above configuration, one of the elastic members 140 ₁ and the other cut 150 between the elastic member 140 ₀ adjacent to each other in the vertical direction is positioned closer to the other elastic member 140 _0. Therefore, in a single cut 150, the lower edge has a small distance from the other resilient member 140 _0, subject to greater tension from the other resilient member 140 _0, the upper edge of one large distance from the elastic member 140 _1, subject to less tension from one of the elastic members 140 _1. Therefore, the lower edge is wrinkled more finely than the upper edge that is further away from the elastic member. Therefore, since the state of the wrinkles formed between the edge on one side of the same cut and the edge on the other side is different, the cut 150 is surely opened.

13A and 13B are diagrams schematically showing the relationship between the direction of the opening of the relative positions and cut 150 of the elastic member 140 ₀ and 140 break 150 between ₁ adjacent to each other in the vertical direction.

When bisector of the distance d between the elastic members 140 ₀ and 140 ₁ adjacent in the longitudinal direction (bisector) and bis, as shown in FIG. 13A, cut 150 than bisector bis when formed under the lower edge of the lower side of the elastic member 140 ₀ distance from the close cut 150, fine under tension T in accordance with the stretching ratio of the elastic member 140 ₀ lower Shiwagayori, upper edge of the cut 150 distance is short from the upper elastic member 140 ₁ is loose wrinkled under tension T in accordance with the upper stretching magnification of the elastic member 140 _1. In this case, the cut 150 creates a downward opening.

In the above case, since the downward opening is formed by the cut 150, when the assistant puts his hand through the leg opening AP _tc of the absorbent article 100 and puts the wearer on the wearer or the assistant, The existence of the break 150 can be recognized with certainty.

In contrast, as shown in FIG. 13B, when the cut 150 is formed above the bisector bis is the lower side of the elastic member 140 ₀ distance from the close cut 150 lower edge, the upper edge of the lower elastic member 140 ₀ stretching more fine wrinkles under tension T in accordance with the magnification, the upper elastic member 140 cut 150 distance from ₁ is short, upper under tension T in accordance with the stretching ratio of the elastic member 140 ₁ by a moderate wrinkles. In this case, the cut 150 creates an upward opening.

In the above case, since the upward opening is formed by the cut 150, when the assistant widens the waist opening AP _wc of the absorbent article 100 and makes the wearer wear it, the wearer or the assistant surely cuts the slit. The existence of 150 can be recognized.

  Here, the elastic members 114, 116, and 140 are arranged between the non-skin-side sheet 118 and the skin-side sheet 120 at a predetermined expansion ratio that represents the degree of expansion when each elastic member is fixed to a sheet or the like in an expanded state. These elastic members express a larger contractile force as the expansion ratio is higher. Therefore, the absorbent article is usually contracted by the contraction force of the elastic member when it is on the market. The “distance between the cut line 150 and the elastic member 140” in the present specification means the “distance in the stretched state” of the absorbent article 100. Therefore, the “extension state of the absorbent article 100” means that when the absorbent article 100 is extended in the horizontal direction and the vertical direction against the contraction force of the elastic members 114, 116, 140, the elastic members 114, The state where it has extended to such an extent that a wrinkle and a gather are substantially invisible in the part in which 116 and 140 are arrange | positioned. The shape of the absorbent article 100 stretched as described above is the shape of the absorbent article 100 when it is flattened in a state where the contraction force by the elastic members 114, 116, and 140 is not expressed.

  FIGS. 14A and 14B are diagrams showing how the opening direction (upper or lower) and the size of the opening differ depending on the distance between the cut 150 and two elastic members 140 adjacent in the vertical direction.

In FIG. 14A, 3 one elastic member 140 ₀ 140 ₁ and 140 _2, are arranged in the longitudinal direction at equal intervals of the yarn Gomupitchi d. A bisector of the distance d between the elastic members 140 ₀ and 140 ₁ is bis ₁ , and a bisector of the distance d between the elastic members 140 ₁ and 140 ₂ is bis ₂ . Between the elastic members 140 ₀ and 140 ₁ , ten cuts 150 ₁₀ ,..., 150 ₁₉ are arranged in different positions at a predetermined slit pitch in the lateral direction, and between the elastic members 140 ₁ and 140 _2. , 10 cut in the transverse direction at different positions at a predetermined slit pitch _0.99 u0, ..., are lined up _{0.99 u9.} FIG. 14A illustrates a case where the vertical interval k of the cut is constant regardless of the position in the horizontal direction, and the rubber thread pitch d and the vertical interval k of the cut are substantially equal.

As shown in FIG. 14A, the cut 150 ₁₀ is located closest to the elastic member 140 ₀ between the elastic members 140 ₀ and 140 ₁ , from which the slit pitch is _increased by one, 150 ₁₁ , each move to ... and laterally cut _{0.99 l1,} ... are formed towards the top in the vertical direction, the position of the cut _{0.99 l5,} cut _{0.99 l5} is located on the bisector bis _1, the position of _{0.99 l9} Then, the cut 150 _l9 is located closest to the elastic member 140 ₁ between the elastic members 140 ₀ and 140 ₁ . In this example, since the distance k in the longitudinal direction of the yarn Gomupitchi d and cuts substantially equal, for example, between the elastic member 140 ₁ and 140 ₂ cuts _{0.99 u0} at the lateral positions equal to the lateral position of the cut _{0.99 l0} vertical position at will substantially the same as the vertical position of the cut _{0.99 l0} between the elastic members 140 ₀ and 140 _1. In addition, the cut 150 _{u5 at} the horizontal position equal to the horizontal position of the cut 150 ₁₅ substantially overlaps the bisector bis ₂ . Therefore, it cuts _{0.99 l0} and cut _{0.99 u0} are both forms a downward largest opening, cut _{0.99 l5} and cut _{0.99 u5} is not substantially open, cut _{0.99 l9} and cut _{0.99 u9} are both upward The largest opening is formed.

On the other hand, FIG. 14B shows a case where the thread rubber pitch d is constant, but the vertical interval k of the cut varies irregularly depending on the position in the horizontal direction. For the lower 10 cuts 150 _lx (x = 0,..., 9) and the upper 10 cuts 150 _ux (x = 0,..., 9), x = 0 to 5 is elastic with the cut 150 _lx. distance _{k l} between the member 140 _1, and with respect to the distance _{k u} between the cut _{0.99 ux} and the elastic member 140 _1, k l> _k indicates _{if u} holds, x = 6 to 9 is, k _The case where _l < _ku is satisfied is shown. In the case of k _{l> k u} is at least one of the cuts _{0.99 lx} and cut _{0.99 ux} forms a downward _opening, in the case of k l _{<k u} is at least one of the cuts _{0.99 lx} and cut _{0.99 ux} Forms an upward opening. For example, both the cut 150 _l0 and the cut 150 _u0 form a downward opening, and for the cut 150 _l1 and the cut 150 _u1 , the cut 150 _l1 forms an upward opening and the cut 150 _u1 forms a downward opening. _{Both l9} and the cut 150 _u9 form an upward opening.

And more generally described the above, for each other and have two elastic members 140 ₀ and the elastic member 140 ₁ adjacent in the longitudinal direction, the distance between the break _{0.99 lx} and the elastic member 140 _{0 d l} and break _{0.99 lx} difference in distance _{d u} between the elastic member 140 is _1, i.e., _{D =} d l when -d took _u, cut _{0.99 lx} when the sign is negative D is downward opening, the sign of D positive At this time, the cut 150 _lx forms an upward opening, and the size of the opening is determined by the size of | D |.

Applying the above principles, when viewed laterally along a resilient member 140 _i, different positions different ways to approach with respect to the elastic member 140 _i with cuts 150, the opening of the cut 150 by the position of the transverse Both the direction and the size of the opening can be made different.

  The principles described above in connection with FIGS. 14A and 14B can be extended to more general aspects.

  FIG. 15 is a diagram illustrating a case where the approaching direction of the cut 150 to the elastic member 140 is different at different places in the same region.

As shown in Figure 15, the right underarm region 134be along transverse ventral side outer member 104 includes a different portion A ₁ and A _2, along transverse ventral side outer member 104 aside region 136be right include different portions _{a 3} and _{a 4.} Three elastic members 140 _l , 140 _m , and 140 _u that are adjacent in the vertical direction are disposed in each of the _four portions A ₁ , A ₂ , A ₃ , and A ₄ . Further, in the portions A ₁ , A ₂ , A ₃ , and A ₄ , a break 150 _l and a break 150 are provided between the elastic members 140 _l and 140 _m and between the elastic members 140 _m and 140 _u , respectively. _u is formed.

In part _{A 1,} a lower break 0.99 _l are formed approached the lower side of the elastic member 140 _l, the upper cut 0.99 _u is formed closer to the upper side of the elastic member 140 _u. Accordingly, the cut 150 _l forms a downward opening, and the cut 150 _u forms an upward opening. In part _{A 2,} both the lower cut 0.99 _l and upper cut 0.99 _u is formed approached the elastic member 140 _m. The elastic member 140 _m is an upper elastic member for the cut 150 _{l and} a lower elastic member for the cut 150 _u . Accordingly, the cut 150 _l forms an upward opening and the cut 150 _u forms a downward opening. In part _{A 3,} the lower side of the cut 0.99 _l are formed approached the lower side of the elastic member 140 _l, cut 0.99 _u side is formed closer to the elastic member 140 _m lower. Accordingly, both the cut 150 _l and the cut 150 _u form a downward opening. In part _{A 4,} the lower side of the cut 0.99 _l are formed closer to the upper side of the elastic member 140 _m, the upper cut 0.99 _u is formed closer to the upper side of the elastic member 140 _u. Accordingly, both the cut 150 _l and the cut 150 _u form an upward opening.

  As described above, for example, different portions such as the armpit regions 136be and 136re and the armpit regions 134be and 134re including a plurality of portions may have different opening directions.

Further, when the distance between a certain cut 150 ₁ and the elastic member 140 _l1 is d _l and the distance between the cut 150 ₁ and the elastic member 140 _u1 is d _u , | D | for a certain cut 150 ₁ = _| d l -d _{u |} values, the other cut 150 ₂ | D | is larger than the value of, among certain upper and lower elastic members ₁₄₀ break 150 _{1 l1} and _{140 u1} at least one of tension may be greater than the tension of the other cut 150 _second elastic member _{140 l2} and _{140 u2.} Here, the tension of the elastic member stretched between the non-skin-side sheet 118 and the skin-side sheet 120 is an expansion ratio that is a degree of expansion when each elastic member is fixed to the sheet or the like in the expanded state. It depends on. The above tension is a tension when the elastic member 140 is stretched on the sheet.

  By doing so, the contraction force of the elastic member can be increased as the degree of deviation of the position of the cut 150 between the two elastic members 140 adjacent in the vertical direction is increased, and the opening is further increased. I can.

  Furthermore, by changing the value of | D | according to the part, both the direction and the size of the opening of the cut 150 can be made different between a certain part and another part.

  FIG. 16 is a diagram illustrating a case where the approaching direction of the cut 150 to the elastic member 140 is different depending on two different regions.

In FIG. 16, one of the two different regions is the left armpit region 134be when viewed in the lateral direction of the ventral-side exterior member 104, and the other of the two different regions is the lateral direction of the ventral-side exterior member 104. As shown in FIG. The cut 150 ^lh _{i, j} with the left armpit region 134be is located at the i-th position from the left and the jth position from the bottom in the left armpit region 134be, and the right armpit region 134be It is assumed that a certain cut 150 ^rh _{m, n} is in the m-th position from the left and the n-th position from the bottom in the right side arm region 134be. The cut 150 ^lh _{i, j} is between the j−1th elastic member 140 _j−1 and the jth elastic member 140 _j counted from the bottom _, and the cut 150 ^rhm _{, n} is n counted from the bottom -1st elastic member _{140 n-1} and counting from the bottom is between n-th elastic members 140 _n. The distance between the cut 150 ^lh _{i, j} and the elastic member 140 _j-1 is d ^lh _{l, i, j} , and the distance between the cut 150 ^lh _{i, j} and the elastic member 140 _j is d ^lh _{u, i, j} , the distance between the slit 150 ^rh _{m, n} and the elastic member 140 _n−1 is ^{dr rh} _{1, m, n} , and the distance between the slit 150 ^rh _{l, m, n} and the elastic member 140 _n is ^{dr rh} _{Let u, m, n} .

A value obtained by dividing the distance between a certain cut and the lower elastic member by the distance between the certain cut and the upper elastic member, that is, {d ^lh _{l, i, j} / d ^lh _{u, i, j} }, and { d ^rh _{l, m, n} / ^{dr rh} _{u, m, n} } is a measure of how close a cut is to either the lower elastic member or the upper elastic member. For example, when the value of {d ^lh _{l, i, j} / d ^lh _{u, i, j} } is close to 0, the cut 150 ^lh _{i, j} is the lower elastic member than the upper elastic member 140 _j 140 _j−1 is arranged close to 1 and when it is close to 1, the cut 150 ^lh _{i, j} is located approximately at the center of the upper elastic member 140 _j and the lower elastic member 140 _j−1. When {d ^lh _{l, i, j} / d ^lh _{u, i, j} } takes a large value, the cut 150 ^lh _{i, j} is elastic above the lower elastic member 140 _j−1. It is situated closer to member 140 _j.

Here, a scale indicating the tendency of the entire region is considered, not a scale of the positional relationship of only a specific break. The scale indicating the tendency of the entire region can be obtained, for example, by averaging the values of {d ^lh _{l, i, j} / d ^lh _{u, i, j} } for all i and j. Left underarm region 134Be average value ^E of ^{_{[d lh l, i, j}} / d lh u, i, j], an average value of the right underarm region _{^{134be E [d rh l, m}} , n / d ^rh _{u, m, n} ], in the illustrated example, E [d ^lh _{l, i, j} / d ^lh _{u, i, j} ] is close to 0 and E [d ^rh _{l, m, n} / d ^rh] _{u, m, n} ] take a large positive value. Accordingly, in this case, the left armpit region 134be has many downward openings when viewed as a whole, and the right armpit region 134be has many upward openings when viewed as a whole.

  In the above example, the case where the formation of the cut is different between the left armpit region 134be and the right armpit region 134be is illustrated, but the opening between the ventral exterior member 104 and the back exterior member 106 is illustrated. It is also possible to adopt different configurations for the orientation and size as a whole.

As described above, when the abdominal exterior member 104 and the back exterior member 106 are compared as a whole, the direction of the opening and the size of the opening of the slit can be made different from each other. For example, ventilation can be adjusted according to the ease of sweating of the body part corresponding to each member of the wearer. Further, the cut 150 is formed so that the average value of the backside exterior member 106 becomes a large positive value or a value close to 0, and the average value in the ventral side exterior member 104 is more than the average value in the backside exterior member 106. If the cut 150 is formed so as to be close to 1, the opening of the cut on the back side where the wearer can easily sweat can be enlarged.
