The body of a wearer who wears a pant-type absorbent article, in particular the body of a baby, has a complex shape in which it has a bulge from the waist to the buttocks, while it curves from the abdomen to the lower abdomen. However, since the pants-type absorbent articles currently manufactured industrially generally have a substantially cylindrical shape, when trying to fit the wearer's body in the wearing state, the above-mentioned buttocks are distorted. On the contrary, there is a possibility that the fit may be deteriorated or the wearing feeling may be deteriorated. Therefore, an object of the present invention is to provide a pants-type absorbent article in which such a disadvantage is eliminated.

The present invention will be described based on its preferred embodiments with reference to the drawings. FIGS. 1 and 2 show a pants-type disposable diaper 1 which is an embodiment of the pants-type absorbent article of the present invention. The diaper 1 comprises an abdominal side A disposed on the ventral side of the wearer in the worn state, and a dorsal side B disposed on the dorsal side of the wearer. The ventral side A and the dorsal side B are portions extending in the longitudinal direction X from the crotch C located between the both. The diaper 1 further comprises an absorbent body 3. The absorbent main body 3 is a substantially rectangular shape having a longitudinal direction X from the abdominal side A to the back side B of the diaper 1 and a width direction Y orthogonal thereto, and the longitudinal direction X of the absorbent main body 3 is It coincides with the longitudinal direction X of the diaper 1.

The diaper 1 has a ventral-side sheet member 2A constituting the ventral-side portion A and a back-side sheet member 2B constituting the back-side portion B. The absorbent main body 3 described above is bridged between the ventral side sheet member 2A and the back side sheet member 2B and is fixed to these

sheet members

2A and 2B. Diaper 1 includes a side area including both side edges 2a1 and 2a1 of ventral side sheet member 2A constituting abdominal side A, and a side including both side edges 2b1 and 2b1 of back side sheet member 2B constituting back side B. It has a pair of side seal parts S and S formed by joining the area. Furthermore, the diaper 1 has a waist opening WO and a pair of leg openings LO, LO.

As shown in FIGS. 2 and 3, the absorbent main body 3 has a liquid-permeable top sheet 31, a liquid-impermeable or water-repellent back sheet 32, and a liquid retaining property disposed between the two

sheets

31 and 32. The absorber 33 of The absorbent body 33 is an absorbent core 331 made of an aggregate of fibers such as pulp fibers and non-woven fabrics or an absorbent core 331 made to hold particles of a water absorbing polymer on this core core and a core wrap for covering the absorbent core 331. The seat 332 is provided.

As shown in FIGS. 2 and 3, leak-

barrier cuffs

34, 34 extending in the longitudinal direction X are disposed on both sides in the width direction Y of the absorbent main body 3. The leak-barrier cuff 34 is made of a liquid-resistant to water-repellent and breathable sheet member. In the vicinity of the free end of each of the leak-barrier cuffs 34, the leak-barrier elastic member 35 is disposed in a stretched state. When the diaper 1 is worn, the leak-barrier elastic member 35 contracts so that the leak-barrier cuff 34 stands up toward the wearer's body. Thereby, the outflow of the liquid from the side edge of the absorbent main body 3 is effectively prevented.

As shown in FIG. 3, on the non-skin facing surface side of the absorbent main body 3 in the crotch C of the absorbent main body 3, an outer sheet 36 is disposed so as to overlap the back surface sheet 32. The outer sheet 36 is used for the purpose of reinforcing the strength of the back sheet 32 or for the purpose of improving the touch of the diaper 1. For this purpose, for example, a non-woven fabric or a film can be used as the outer sheet 36.

The absorbent main body 3 has

leg cuffs

37, 37 extending along the longitudinal direction X at positions outward of the respective leakproof cuffs 34 in the width direction Y. At the free end of the leg cuff 37, a leg cuff elastic member 38 extending in the longitudinal direction X is attached in an extended state. The leg cuffs 37 fit around the legs of the wearer when the diaper 1 is worn.

As shown in FIGS. 2 and 4, the absorbent main body 3 overlaps the back sheet member 2 </ b> B at one end side in the longitudinal direction X. In the overlapping portion, both are fixed via the adhesive 39. Similarly, the absorbent main body 3 overlaps the abdominal sheet member 2A at the other end side in the longitudinal direction X, and both are fixed via an adhesive (not shown) at the overlapping portion.

As shown in FIG. 2, the ventral sheet member 2 </ b> A and the back sheet member 2 </ b> B are both substantially rectangular. The

members

2A and 2B have substantially the same length in the width direction Y, and the length in the longitudinal direction X of the back side sheet member 2B is longer than that of the abdominal side sheet member 2A. And both side members are joined and the side seal part S is formed under the state which made the upper end part of those both-sides 2a1, 2b1 correspond, as for both

sheet members

2A and 2B. Therefore, the length of the side seal portion S along the longitudinal direction X matches the length of the ventral side sheet member 2A along the longitudinal direction X. On the other hand, the back side sheet member 2B, when viewed along the longitudinal direction X, extends toward the crotch C from the region where the side seal portion S is formed and the side seal portion S. It is divided into areas. In the following description, when the back side sheet member 2B is viewed in the longitudinal direction X, the area in which the side seal portion S is formed is called the back side main body portion 20b, and the lower side than the side seal portion S. The extended region is called a back extension 21b. The part of the back extension part 21 b located on the outer side in the width direction Y than the side edge of the absorbent main body 3 becomes a buttocks cover part that covers the buttocks of the wearer when the diaper 1 is worn.

The ventral side A and the dorsal side B of the diaper 1 respectively extend outwardly in the width direction Y from the imaginary line 3b extending in the longitudinal direction passing over the side edges 3a of the absorbent main body 3 29A and a back side panel 29B. The ventral side panel 29A extends between the side edge 2a1 of the ventral side sheet member 2A and the side edge 3a of the absorbent main body 3 in the width direction Y. In the longitudinal direction X, it extends between one end 2a2 of the ventral side sheet member 2A and the other end 2a3. On the other hand, the back side panel 29B extends between the side edge 2b1 of the back side sheet member 2B and the side edge 3a of the absorbent main body 3 in the width direction Y. The longitudinal direction X extends from the edge 2b2 on the waist opening side of the back sheet member 2B to the boundary between the back main body 20b and the back extension 21b.

The ventral side panel 29A and the back side panel 29B constitute a part of the ventral sheet member 2A and the back sheet member 2B, respectively. The ventral-side sheet member 2A including the ventral-side side panel 29A has a composite sheet provided with an outer sheet 22 forming the outer surface of the diaper and an inner sheet 23 disposed on the inner surface side of the outer sheet 22. Similarly, the back sheet member 2B including the back side panel 29B also has a composite sheet provided with an outer sheet 22 forming the outer surface of the diaper and an inner sheet 23 disposed on the inner surface side of the outer sheet 22. . Each of the outer sheet 22 and the inner sheet 23 can be independently used, for example, a non-stretchable sheet. A stretchable sheet can also be used for any one of the outer sheet 22 and the inner sheet 23. For example, when an elastic sheet is used for the outer sheet 22 and a non-elastic sheet is used for the inner sheet 23, the ridges are formed only on the inner sheet 23, so that the fit and air permeability are improved. is there. In the case where both the outer sheet 22 and the inner sheet 23 are stretchable sheets, the extension ratios may be different from each other.

The composite sheet constituting the ventral side panel 29A and the back side panel 29B includes a plurality of elastic members 24 extending between the outer sheet 22 and the inner sheet 23 and extending along the width direction Y. There is. Each elastic member 24 is fixed in an extended state. Accordingly, the composite sheet including the ventral side panel 29A and the back side panel 29B is stretchable in the width direction Y. However, a portion 24 a of the elastic member 24 overlapping with the absorbent main body 3 is processed so as not to exhibit stretchability. As such a process, for example, a process of finely cutting the elastic member 24 at the portion 24a and the like can be mentioned, but it is not limited thereto.

As shown in FIG. 2 and FIG. 5, in the ventral side panel 29A, the outer sheet 22 and the inner sheet 23 are joint portions 25 formed intermittently along the longitudinal direction X and the width direction Y of the side panel 29A. , 27 are joined. The elastic member 24 is disposed so as not to pass through the

joints

25 and 27. Further, the elastic member 24 is in a non-bonded state to both the outer sheet 22 and the inner sheet 23 in the region between both ends in the width direction Y, and the outer sheet 22 and the inner sheet 23 only in the both ends in the width direction Y. And fixed. In addition, FIG. 5 is a top view which shows the principal part of the state which extended | stretched the diaper 1 shown in FIG. 1 flatly centering on the side seal part S. FIG.

Similarly, also in the back side panel 29B, the outer sheet 22 and the inner sheet 23 are joined at joining

portions

26, 28 formed intermittently along the longitudinal direction X and the width direction Y of the side panel 29B. There is. The elastic member 24 is disposed so as not to pass through the joint portion 28. Further, the elastic member 24 is in a non-bonded state to both the outer sheet 22 and the inner sheet 23 in the region between both ends in the width direction Y, and the outer sheet 22 and the inner sheet 23 only in the both ends in the width direction Y. And fixed.

The above-described

bonding portions

25 and 27 and the

bonding portions

26 and 28 can be formed by, for example, fusion bonding such as various adhesives such as a hot melt adhesive or heat sealing. When a hot melt adhesive is used, coating by a stripe coater is preferable, but a summit or spiral may be coated along the longitudinal direction X. On the other hand, in the case of heat sealing, the joints may be continuous, but from the viewpoint of maintaining the softness of the

side panels

29A and 29B and improving the air permeability, the joints are intermittently joined along the longitudinal direction X It is preferable to provide a part.

The bonding portions 25 formed on the ventral side panel 29A are arranged such that a plurality of the bonding portions 25 form a straight bonding portion row 25L along the longitudinal direction X of the ventral side panel 29A. The joint row 25L is formed in a plurality of rows at intervals in the width direction Y of the ventral side panel 29A. Similarly, the bonding portions 27 are also arranged such that a plurality of the bonding portions 27 form a straight bonding portion row 27L along the longitudinal direction X of the abdominal side panel 29A. The joint row 27L is formed in a plurality of rows at intervals in the width direction Y of the ventral side panel 29A.

On the other hand, the bonding portions 26 formed on the back side panel 29B are arranged such that the plurality of bonding portions 26 form a straight bonding portion row 26L along the longitudinal direction X of the back side panel 29B. There is. The joint row 26L is formed in a plurality of rows at intervals in the width direction Y of the back side panel 29B. Similarly, the bonding portions 28 are also arranged such that a plurality of the bonding portions 28 form a straight bonding portion row 28L along the longitudinal direction X of the back side panel 29B. The joint row 28L is formed in a plurality of rows at intervals in the width direction Y of the back side panel 29B.

In the ventral side panel 29A, the elastic members 24 arranged in the stretched state contract in the relaxed state of the diaper 1, that is, in the natural state, and as shown in FIG. , 25L, so that the outer sheet 22 is deformed to expand outward, and the inner sheet 23 is deformed so as to expand toward the wearer's body. Then, between the adjacent

joint portion rows

25L and 25L,

ridges

29a and 29a formed of the outer sheet 22 and the inner sheet 23 are generated. In other words, each of the outer sheet 22 and the inner sheet 23 forms a plurality of rows of ridges 29 a extending continuously across the plurality of elastic members 24. Further, between the outer sheet 22 and the inner sheet 23, a hollow portion 2H surrounded by the collar portion 29a and the collar portion 29a is formed. The collar portion 29a and the hollow portion 2H extend along the longitudinal direction X of the side panel 29A.

Similarly, as shown in FIG. 6, the outer sheet 22 between the

joint row

27L and 27L adjacent in the width direction Y is deformed so as to expand outward, and the inner sheet 23 is a wearer's body. It deforms as it bulges to the side. Then, between the adjacent

joint portion rows

27L and 27L,

ridge portions

29b and 29b formed of the outer sheet 22 and the inner sheet 23 are generated. Further, between the outer sheet 22 and the inner sheet 23, a hollow portion (not shown) surrounded by the collar portion 29b and the collar portion 29b is formed. The collar portion 29b and the hollow portion (not shown) extend along the longitudinal direction X of the side panel 29A.

As with the ventral side panel 29A, also for the dorsal side panel 29B, the outer sheet 22 between the

joint rows

26L and 26L and between the

joint rows

28L and 28L expand outward. It deforms and deforms so that the inner sheet 23 bulges toward the wearer's body side. As a result, a ridge (not shown) consisting of the outer sheet 22 and the inner sheet 23 is generated between the adjacent

joint rows

26L and 26L and between the

joint rows

28L and 28L, and a hollow portion (see FIG. Not shown) is formed. The ridge (not shown) and the hollow (not shown) extend in the longitudinal direction X of the side panel 29B.

By the way, as shown in FIG. 2 and FIG. 5, although both of the joint row 25L and the joint row 27L formed in the abdominal side panel 29A extend along the longitudinal direction X, both

joint rows

25L , 27L do not exist in the same straight line, and are shifted with respect to the width direction Y. As a result, as shown in FIG. 6, the ridges 29a formed by the joint row 25L and the ridges 29b formed by the joint row 27L do not exist in the same straight line, and both

ridges

29a, 29b is shifted with respect to the width direction Y. In other words, in the ventral side panel 29A, the

ridges

29a and 29b are shifted in the width direction Y at predetermined positions in the longitudinal direction X, and the continuity in the longitudinal direction X is broken. In the present embodiment, the predetermined position is located at the boundary P between the joint row 25L and the joint row 27L, as shown in FIGS. A boundary P between the joint row 25L and the joint row 27L linearly extends in the width direction Y.

On the other hand, with regard to the back side panel 29B, as shown in FIGS. 2 and 5, both the joint row 26L and the joint row 28L formed in the back side panel 29B extend along the longitudinal direction X. Although both

joint rows

26L and 28L do not exist in the same straight line, they are shifted with respect to the width direction Y. As a result, the ridges (not shown) formed by the joint row 26L and the ridges (not shown) formed by the joint row 28L do not exist in the same straight line, and both ridges Is shifted with respect to the width direction Y. In other words, in the back side panel 29B, both ridges shift in the width direction Y at a predetermined position in the longitudinal direction X (see FIG. 5), and the continuity in the longitudinal direction X is broken. In the present embodiment, as shown in FIG. 5, the predetermined position is located at the boundary Q between the joint row 26L and the joint row 28L. The boundary Q between the joint row 26L and the joint row 28L extends linearly along the width direction Y. The boundary Q and the above-described boundary P are at the same position when viewed along the longitudinal direction X of the diaper 1. The boundary Q and the boundary P are in the same straight line extending along the width direction Y. It is preferable that the boundary P and the boundary Q be located anywhere in the range in which the side seal portion S is formed when viewed along the longitudinal direction X of the diaper 1. The “same position” means that the distance from the edge 2a2 of the ventral sheet member 2A to the boundary P is equal to the distance from the edge 2b2 of the back sheet member 2B to the boundary Q, and It says that the difference is within 10 mm in diapers for infants and within 20 mm in diapers for adults.

In the present embodiment, that the continuity of the buttocks in the longitudinal direction X at the boundaries P and Q is broken means that the top of the buttocks is bent at the boundaries P and Q. In order to break the continuity of the buttocks in the longitudinal direction X at the boundaries P and Q, the degree of displacement of the joint row 25L and the joint row 27L along the width direction Y, and the joint row 26L It is preferable to independently set the degree of deviation along the width direction Y between the and the joint row 28L to 1 mm or more and 20 mm or less, more preferably 2 mm or more and 15 mm or less, and set 3 mm or more and 10 mm or less Is more preferred.

When the diaper 1 of the present embodiment is worn, the

side panels

29A, 29B are deformed to a shape corresponding to the unevenness of the wearer's body. Along with the deformation, buttocks extending in the longitudinal direction X and formed on the ventral side panel 29A and the dorsal side panel 29B are also bent at the boundaries P and Q. At this time, if the positions of the boundaries P and Q in the mounted state are the same, as shown in FIG. 7, the bent portions at the boundaries P and Q will be continuous. As a result, the diaper 1 has a good fit in the wearing state and exhibits a good wearing feeling. From this point of view, it is preferable that the position at which the buttocks are shifted in the width direction Y between the ventral side panel 29A and the back side panel 29B is the same in the attached state of the diaper 1.

The positions of the boundaries P and Q can be appropriately determined in consideration of the fit and the like of the

side panels

29A and 29B in the diaper 1. For example, as shown in FIG. 2, along the longitudinal direction X of each

side panel

29A, 29B, a waist region D1 including the waist opening WO of the diaper 1, a crotch region D2 positioned on the crotch side, and both When divided into the middle region D3 located between the regions, at least a part of a plurality of rows of ridges extending in the longitudinal direction X in each

side panel

29A, 29B is shifted in the width direction Y in the middle region D3. Preferably, the continuity in the longitudinal direction X of the buttocks is interrupted. It is preferable that, for example, a section between the waist area D1, the crotch area D2, and the middle area D3 in each

side panel

29A, 29B be a middle area D3 in the range of 15% to 85% from the lower end of the side seal portion. An area located closer to the waist opening than the intermediate area D3 is preferably the waist area D1, and an area located closer to the crotch C than the intermediate area D3 is preferably the crotch area D2.

Boundaries P and Q, which are positions where the ridges are shifted in the width direction Y, are each independently 15% or more away from the lower end of the side seal portion with respect to the length in the longitudinal direction X of the side seal portion S It is preferable that the distance be 20% or more, particularly 25% or more. The boundaries P and Q are each independently preferably within 85% of the lower end of the side seal portion S, and particularly preferably within 70%, particularly within 60%. Specifically, the boundaries P and Q are preferably independently within the range of 15% to 85% from the lower end of the side seal portion S, particularly 20% to 70%, particularly 25% to 60%. It is preferable to be in the range of By providing the boundaries P and Q within this range, the fit in the attached state of the diaper 1 is further enhanced, and the diaper 1 exhibits a better fit.

In the ventral side panel 29A and the back side panel 29B, at least a part of the ridges formed on them is shifted in the width direction Y at a predetermined position in the longitudinal direction X, and the longitudinal direction of the ridges The continuity over X may be interrupted. Alternatively, from the viewpoint of further enhancing the fit in the wearing state of the diaper 1 and further improving the wearing feeling of the diaper 1, the buttocks across the entire width direction Y of the ventral side panel 29A and the back side panel 29B. The ridge portion is shifted in the width direction Y at a predetermined position in the longitudinal direction X over the entire region in the width direction Y of each

side panel

29A, 29B to cut the continuity in the longitudinal direction X of the ridge portion. May be

As shown in FIG. 5, in the ventral side panel 29A, the pitch L1 of the ridges located on the waist opening side with respect to the boundary P with the boundary P at which the ridges are shifted in the width direction Y The pitch L2 of the buttocks located closer to the crotch than the boundary P is the same. The same pitch means that the pitch L1 and the pitch L2 are equal, and the difference between the two pitches is 2 mm or less in diapers for infants and 4 mm or less in diapers for adults (below The same applies to the pitch L3 and the pitch L4 described). The same applies to the back side panel 29B, and the pitch L3 of the buttocks located on the waist opening side with respect to the boundary Q with the boundary Q at which the buttocks are shifted in the width direction Y The pitch L4 of the buttocks located on the crotch side is the same as the pitch L4. By doing this, the fit in the attached state of the diaper 1 is further enhanced, and the diaper 1 comes to have a better fit. In this case, the pitch L1 and the pitch L3 may be the same or different. In addition, although the buttocks are generated in the relaxed state of the diaper 1, FIG. 5 shows a state in which the diaper 1 is stretched, so the pitches L1 to L4 indicate the pitches of the joint portion row, The pitch is different from the pitch of the actual heel. However, since the pitch of the ridge portion generally correlates with the pitch of the joint row, the description of the pitch of the ridge portion is replaced by focusing on the pitch of the joint row.

The pitch L1 in the abdominal side panel 29A and the pitch L3 in the back side panel 29B are the degree of deviation of the joint row 25L and the joint row 27L along the width direction Y, and the joint row 26L and the joint row It is preferable that they are independently 1 mm or more and 20 mm or less, more preferably 3 mm or more and 15 mm or less, and more preferably 5 mm or more and 10 mm, on condition that the degree of displacement with 28 L in the width direction Y is the above mentioned range It is more preferable that

8 to 13 show another embodiment of the pants-type absorbent article of the present invention. In these embodiments, only differences from the embodiment shown in FIGS. 1 to 7 will be described, and the description of FIGS. 1 to 7 will be applied as appropriate to points that are not particularly described. In FIGS. 8 to 13, the same members as those in FIGS. 1 to 7 are denoted by the same reference numerals.

In the embodiment shown in FIGS. 1 to 7, although the continuity of the buttocks in the longitudinal direction X is broken in both the ventral side panel 29A and the back side panel 29B, instead of this, the ventral side panel The continuity of the buttocks along the longitudinal direction X may be broken in only one of 29A and the back side panel 29B. For example, in the embodiment shown in FIG. 8, in the ventral side panel 29A, the formation position of the joint row 25L and the junction such that the continuity in the longitudinal direction X of the buttocks is interrupted at the upper and lower sides of the boundary P The formation position of the partial row 27L is shifted in the width direction Y. On the other hand, in the back side panel 29B, only the joint row 26L is formed over the entire area in the longitudinal direction X, so the ridges formed by the joint row 26L correspond to the longitudinal direction X of the back side panel 29B.
