The disposable diaper described in Patent Literature 1 is formed by fixing the absorbent main body via each absorbent body fixing sheet in a state in which the exterior body is stretched in the horizontal direction. The absorbent body fixing sheet is fixed between the exterior body and the absorbent main body without any gap. Therefore, in the diaper described in Patent Literature 1, the lateral stiffness of the absorbent body inhibits the lateral expansion and contraction of the outer package, which causes random wrinkles in the outer package, resulting in poor aesthetics. In addition, Patent Document 1 does not describe anything about preventing the leakage of bodily fluids by moving the absorbent main body according to the movement of the wearer to fit the absorbent body.

In addition, Patent Document 2 does not describe at all an exterior body that constitutes the appearance of a disposable diaper and has stretchability over the entire surface.

Accordingly, an object of the present invention is to provide a wearing article that suppresses deterioration of aesthetics, allows the absorbent main body to easily move with the movement of the wearer when worn, improves fit, and prevents leakage of bodily fluids. about doing

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described below based on its preferred embodiments with reference to the drawings. 1 to 4 show an underpants-type disposable diaper 1, which is one embodiment of the wearing article of the present invention. As shown in FIGS. 1 to 4, the diaper 1 has a longitudinal direction X corresponding to the front-rear direction of the wearer, that is, a direction extending from the abdomen to the back through the crotch, and a lateral direction Y orthogonal thereto. have. A diaper 1 includes an absorbent body 2 and an outer body 3 arranged on the non-skin facing side of the absorbent body 2 .

As used herein, the term “skin-facing surface” refers to the surface of the disposable diaper or its constituent members (e.g., topsheet) that faces the wearer's skin when the disposable diaper is worn, that is, is relatively close to the wearer's skin. The "non-skin-facing side" is the side of the disposable diaper or its components that faces away from the skin when the disposable diaper is worn, i.e., the side that is relatively far from the wearer's skin. It should be noted that the term "when worn" as used herein means a state in which the disposable diaper is maintained in a normal proper wearing position, that is, in a proper wearing position of the disposable diaper.

As shown in FIGS. 1 and 2, the diaper 1 has a crotch portion M, and an abdominal portion F and a back portion R extending in the longitudinal direction X from the front and rear of the crotch portion M. As shown in FIGS. The crotch portion M is a portion arranged between the crotch portion of the wearer when the diaper 1 is worn, and the abdomen portion F is located closer to the wearer's abdomen than the crotch portion M when the diaper 1 is worn, that is, in the longitudinal direction X. The back side portion R is a portion that is arranged on the back side of the wearer, that is, on the rear side in the longitudinal direction X, relative to the crotch portion M when the diaper 1 is worn. The abdominal side portion F and the dorsal side portion R are waist-surrounding portions arranged around the wearer's waist when the diaper 1 is worn.

In the diaper 1, both side edges along the longitudinal direction X of the exterior body 3 in each of the abdominal part F and the back part R are joined to each other by a known joining means such as an adhesive, heat sealing, or ultrasonic sealing. there is As shown in FIG. 1, the diaper 1 includes a pair of side seal portions S, S, a waist opening WH through which the wearer's torso is passed, and a pair of leg openings through which the wearer's lower legs are passed. This is a pants-type disposable diaper in which LH and LH are formed.

As shown in FIGS. 3 and 4, the absorbent body 2 comprises a liquid-permeable top sheet 21 forming a skin-facing surface and a liquid-impermeable or liquid-impermeable back sheet 22 forming a non-skin facing surface. , and a liquid-retaining absorber 23 interposed between the sheets 21 and 22, which are integrated by a known bonding means such as an adhesive. The topsheet 21 is formed such that the lengths in the vertical direction X and the horizontal direction Y are substantially the same as the lengths in the vertical direction X and the horizontal direction Y of the absorber 23, respectively. The length in the longitudinal direction X of the backsheet 22 is substantially the same as the length in the longitudinal direction X of the absorber 23 . The back sheet 22 is formed so that the length in the horizontal direction Y is longer than the length in the horizontal direction Y of the absorbent body 23, and each side portion of the absorbent body 23 along the vertical direction X is covered. is rolled up on the skin-facing side of the Thus, the skin-facing surface of the absorbent body 23 is covered with the topsheet 21 , and the non-skin-facing surface of the absorbent body 23 is covered with the backsheet 22 .

The absorbent core constituting the absorbent body 23 has a rectangular shape elongated in the longitudinal direction X in the unfolded and stretched state of the diaper 1 as shown in FIG. extends to As shown in FIG. 2, regarding the total length in the vertical direction X, the absorbent main body 2 and the absorbent body 23 have substantially the same length, and both ends of the absorbent main body 2 in the vertical direction X are equal to the length of the absorbent body 23 in the vertical direction X. are at approximately the same positions as both ends of the . In addition, as shown in FIGS. 2 to 4, regarding the total length in the horizontal direction Y, the absorbent main body 2 and the absorbent main body 23 have substantially the same length, and both side edges of the absorbent main body 2 along the vertical direction X are It is located at substantially the same position as both side edges along the longitudinal direction X of the absorber 23 . The "unfolded and stretched state" of the diaper 1 means that the diaper 1 is cut off at the side seal portion S to be in the unfolded state, and the elastic members of each part of the diaper 1 in the unfolded state are stretched to the design size (the influence of the elastic member is completely removed). It means the state in which it is expanded until it becomes the same dimension as when it is expanded in a flat state in the excluded state).

As the top sheet 21, the back sheet 22 and the absorbent body 23, various materials conventionally used in absorbent articles such as disposable diapers can be used without particular limitation. For example, as the surface sheet 21, a nonwoven fabric having a single-layer or multi-layer structure, a perforated film, or the like can be used. As the back sheet 22, a moisture-permeable resin film or the like can be used. As the absorbent body 23, an absorbent core made of an absorbent material composed of absorbent polymer particles and fibrous material covered with tissue paper can be used.

The outer body 3 extends outward from the entire circumference of the absorbent main body 2 in the diaper 1 in the unfolded and stretched state as shown in FIG. The peripheral edge of the outer body 3 forms the contour lines of the diaper 1 in the state shown in FIG. In the exterior body 3, the length in the lateral direction Y at the ventral part F and the dorsal part R is longer than the length in the lateral direction Y at the crotch part M, and in a plan view as shown in FIG. Both side edges along the direction X are curved inwardly in the lateral direction Y in the shape of a convex arc at the crotch portion M.

In the diaper 1 , the outer body 3 has elasticity in the lateral direction Y over the entire area from the ventral side F to the dorsal side R of the outer body 3 . As used herein, the term "elasticity" means the property of being able to stretch in a given direction and shrinking when the stretch is released. Examples of stretchable sheets that can be used for the exterior body 3 having stretchability include, in addition to a stretchable sheet in which a stretchable member in a stretched state is arranged between two sheets, for example, (1) both sides of an elastic fiber layer that spreads in a plane, or (2) A stretchable sheet in which an extensible fiber layer is integrated on one side or both sides of a net-like elastic sheet that spreads over a plane; (3) A stretch sheet in which extensible fiber layers are integrated on both or one side of an elastic film that spreads in a plane, (4) a large number of elastic filaments arranged so as to extend in one direction without A stretch sheet or the like that is bonded to a stretchable nonwoven fabric over its entire length in a non-stretched state can be preferably used. Methods for integrating the elastic fiber layer and the extensible fiber layer include, for example, a method of laminating them and hydroentangling them, a method of air-through entangling the fibers, heat embossing, an adhesive, ultrasonic waves, and the like. There is a method of joining by The stretch sheets (1) to (3) may have stretchability not only in the lateral direction Y but also in all directions. The form (4) has the advantage that it is possible to design the right material for the right place by changing the stretch rate of the elastic filament according to the curvature of the body. In the diaper 1, a stretchable sheet in which a stretchable member in a stretched state is arranged between two sheets is used for the outer body 3. As shown in FIG.

As shown in FIG. 2, the outer body 3 is formed by stacking an outer layer sheet 31 forming the outer surface of the diaper 1 and an inner layer sheet 32 disposed on the skin facing side of the outer layer sheet 31 . The outer layer sheet 31 and the inner layer sheet 32 are formed to have the same shape and size. The elastic member 33 is continuous over the entire length in the horizontal direction Y of the exterior body 3 . The elastic members 33 are arranged from the ventral portion F to the dorsal portion R via the crotch portion M at intervals in the longitudinal direction X without intersecting each other. joined to at least one side. The exterior body 3 is expandable and contractable in the lateral direction Y, which is the same direction as the direction in which the elastic member 33 extends (lateral direction Y), over the entire area from the ventral portion F to the dorsal portion R.

As shown in FIGS. 2 to 4, the diaper 1 is provided with anti-leakage cuffs 4 on both sides 2S, 2S of the absorbent main body 2 along the longitudinal direction X. As shown in FIGS. The leak-proof cuff 4 is composed of a water-repellent cuff-forming sheet 41 continuous over the entire length of the absorbent main body 2 in the longitudinal direction X, and a free end of the cuff-forming sheet 41 in the lateral direction Y extending in the longitudinal direction X. 1 or a plurality of cuff elastic members 42 fixed in a state. An upper cuff fixing portion 51a to which the leak-proof cuff 4 and the topsheet 21 are fixed along the longitudinal direction X is formed on the skin-facing surface of each of the side portions 2S, 2S of the absorbent main body 2. As shown in FIG. The upper cuff fixing portion 51a is formed by fixing the cuff forming sheet 41 to the skin facing surface of the topsheet 21 of the absorbent main body 2, and extends over the entire length of the absorbent main body 2 in the longitudinal direction X. there is In the diaper 1, the cuff fixing portion 51a on the upper side serves as a starting end portion when the leakage prevention cuff 4 rises toward the wearer's skin when the diaper 1 is worn. Further, in the diaper 1, the cuff-forming sheet 41 is formed so as to extend outward in the lateral direction Y from the side edge of the side portion 2S of the absorbent body 2 beyond the upper cuff fixing portion 51a. The side portion 2S is rolled down from the skin-facing surface side to the non-skin-facing surface side so as to cover the two side portions 2S. On the non-skin-facing surfaces of the side portions 2S, 2S of the absorbent main body 2, one end portion of the rolled-down leak-proof cuff 4 and the back sheet 22 are fixed along the longitudinal direction X on the lower side. A cuff fixing portion 51b is formed. The cuff fixing portion 51b on the lower side is formed by fixing the cuff forming sheet 41 to the non-skin facing surface of the back sheet 22 of the absorbent main body 2. extended. Thus, the diaper 1 has a cuff fixing portion 51 comprising an upper cuff fixing portion 51a and a lower cuff fixing portion 51b. The leak-proof cuff 4 is fixed to the side portion 2S of the absorbent main body 2 at the upper cuff fixing portion 51a and the lower cuff fixing portion 51b, and the upper cuff fixing portion 51a and the lower cuff fixing portion 51b are arranged so as to overlap in the thickness direction.

In the horizontal end view of the crotch portion M of the diaper 1 with the outer body 3 stretched shown in FIG. The width of overlap in the thickness direction with the length in the horizontal direction Y depends on how much the length in the horizontal direction Y of the lower cuff fixing portion 51b overlaps with the length in the horizontal direction Y of the upper cuff fixing portion 51a. to decide. The overlapping width is preferably 60% or more, more preferably 80% or more, and particularly preferably 100%. In addition, when the overlap width is 100%, the length of the upper cuff fixing portion 51a in the horizontal direction Y and the length of the lower cuff fixing portion 51b in the horizontal direction Y match in the thickness direction and overlap each other. In addition, it means that the length in the horizontal direction Y of the lower cuff fixing portion 51b is included within the range in the horizontal direction Y of the upper cuff fixing portion 51a.

The leakage-preventing cuff 4 is absorbed by a cuff-forming sheet 41 forming a free end, which is the other end of the leakage-preventing cuff 4, at each of the ventral side end and the dorsal side end in the longitudinal direction X of the absorbent main body 2. It is fixed to the skin facing surface of the topsheet 21 on the body 23 . When the diaper 1 is worn, the cuff elastic member 42 is contracted in the longitudinal direction X, and the leak-proof cuff 4 has a free end portion at which the cuff elastic member 42 is arranged starting from the upper cuff fixing portion 51a at least in the crotch portion M. is designed to stand against the wearer's skin. As the cuff-forming sheet 41 and the cuff elastic members 42, various materials conventionally used in absorbent articles such as disposable diapers can be used without particular limitation.

As shown in FIGS. 3 and 4, the absorbent main body 2 and the exterior body 3 are not directly joined, but are fixed via a sheet member 6 disposed between the absorbent main body 2 and the exterior body 3. It is The sheet member 6 extends in the vertical direction X, and the total length of the sheet member 6 in the vertical direction X and the total length of the absorbent body 2 in the vertical direction X are substantially the same. In the diaper 1, a pair of sheet members 6 are arranged in regions including positions respectively corresponding to the side portions 2S, 2S along the longitudinal direction X of the absorbent main body 2, and are arranged at intervals.
In the sectional view shown in FIG. 3 and the end view shown in FIG. 4, it is shown that there is a large gap between the absorbent main body 2 and the exterior body 3, but this is a schematic diagram for explanation. This is because it is shown in the figure, and in reality the large gap does not occur, and the absorbent main body 2 and the exterior body 3 are close to each other.

Each of the pair of sheet members 6, 6 is formed of one sheet. As shown in FIGS. 3 and 4, each sheet member 6 is folded so that the central portion in the lateral direction Y is outwardly convex. At the crotch portion M, the sheet member 6 is exposed from both sides of the exterior body 3 in the natural state of the exterior body 3 shown in FIG. 4(b). Here, in the present specification, the “natural state” refers to a state in which the diaper 1 is worn alone (that is, a state in which it is not worn), and a relaxed state in which no external force is applied to the outer package 3 .

As the sheet member 6, a single-layer or multi-layer nonwoven fabric, a film sheet, or the like can be used, and from the viewpoint of preventing leakage of body fluids, etc., it is preferably liquid-impermeable or liquid-impermeable. . In addition, since the sheet member 6 is exposed from both sides of the outer body 3 in the natural state of the outer body 3 shown in FIG. It is preferable to use the same color or a similar color as that of the exterior body 3 from the viewpoint of facilitating the appearance. A similar color means a color of the same system and having the same or similar hue. When a pattern, pattern, or the like is printed on the exterior body 3, it is preferable that the sheet member 6 is similarly printed with the same or similar print as the pattern, pattern, or the like of the exterior body 3. By printing on the sheet member 6 the same as or similar to the pattern or pattern of the exterior body 3, the aesthetic appearance of the diaper 1 when worn can be further improved. When a nonwoven fabric is used as the sheet member 6, the basis weight of the nonwoven fabric is preferably 8 g/m ² or more, more preferably 13 g/m ² or more, and preferably 30 g/m ² or less, further preferably 20 g/m ² or less. is.

As shown in FIGS. 3 and 4, the diaper 1 includes a main body fixing portion 52 in which the sheet member 6 is fixed to the non-skin facing side of the absorbent main body 2 along the longitudinal direction X, and the outer covering 3 facing the skin. An exterior body fixing portion 53 to which the sheet member 6 is fixed along the longitudinal direction X is provided on the surface. In the sheet member 6, one end portion 61 disposed on the side of the absorbent main body 2 in the lateral direction Y is the leak-proof cuff 4 fixed to the non-skin-facing surface of the absorbent main body 2 by the lower cuff fixing portion 51b. is fixed to one end of the main body fixing portion 52 via the main body fixing portion 52 . In the body fixing portion 52 , one end portion 61 of the sheet member 6 is fixed to the non-skin facing side of the absorbent body 2 in a belt-like surface contact state. The main body fixing portion 52 is formed in a strip shape extending in the vertical direction X, and the total length of the main body fixing portion 52 in the vertical direction X and the total length of the sheet member 6 in the vertical direction X are substantially the same length. Further, in the sheet member 6 , the other end portion 62 arranged on the exterior body 3 side is fixed to the skin-facing surface of the exterior body 3 via the exterior body fixing portion 53 in the lateral direction Y. As shown in FIG. The other end portion 62 of the sheet member 6 is fixed to the skin facing surface of the exterior body 3 at the exterior body fixing portion 53 in a belt-like surface contact state. Like the body fixing portion 52, the exterior body fixing portion 53 is formed in a belt shape extending in the vertical direction X, and the total length of the exterior body fixing portion 53 in the vertical direction X and the total length of the sheet member 6 in the vertical direction X are equal to each other. are approximately the same length. In the natural state of the diaper 1, the sheet member 6 is arranged along the wrinkles formed in the outer body 3 in the outer body fixing portion 53, as shown in FIGS. 3(b) and 4(b). state. In the diaper 1 , the main body fixing portion 52 and the exterior body fixing portion 53 are formed on the same surface of the sheet member 6 because the sheet member 6 is folded outwardly.

The main body fixing portion 52 and the exterior body fixing portion 53 can be formed by adhesive or heat-sealing. In the diaper 1, the adhesive is applied. As the adhesive to be applied, known adhesives for absorbent articles such as disposable diapers, such as hot-melt pressure-sensitive adhesives, can be used. The adhesive may be applied continuously over the entire surface, but it is preferable to apply the adhesive in a pattern in which coated portions and non-coated portions are mixed. Coating patterns for pattern coating include a spiral pattern, a stripe pattern, a dot pattern, and the like.

The main body fixing portion 52 has, as both side edges along the longitudinal direction X of the main body fixing portion 52, a side edge 52S on the non-fixed portion 63 side and a side edge on the opposite side to the side edge 52S. Here, the side edge 52S of the main body fixing portion 52 is the side edge closer to the edge of the non-fixing portion 63 on the side of the absorbent main body 2 among both side edges along the longitudinal direction X of the main body fixing portion 52. . Similarly, the exterior fixing portion 53 has a side edge 53S on the non-fixing portion 63 side and a side edge opposite to the side edge 53S as both side edges along the longitudinal direction X of the exterior fixing portion 53. is doing. Here, the side edge 53S of the exterior body fixing portion 53 is the side edge closer to the edge of the non-fixing portion 63 on the side of the exterior body 3 among the side edges along the longitudinal direction X of the exterior body fixing portion 53. be.

From the viewpoint of improving the aesthetics of the diaper 1 in the appearance of the diaper 1 when worn, as shown in FIG. , the side edge 53S of the exterior body fixing portion 53 on the non-fixed portion 63 side is located laterally Y outside the side edge 52S on the non-fixed portion 63 side of the main body fixing portion 52. preferably. Such a relationship is preferably established in both the ventral portion F and the dorsal portion R, and as shown in FIG. It is more preferable that the above holds for M as well. In particular, when the main body fixing portion 52 and the exterior body fixing portion 53 are formed as a pair, respectively, as in the diaper 1, the entire area of each exterior body fixing portion 53 is on the side of the non-fixing portion 63 of the main body fixing portion 52. It is more preferable that the side edge 52S of the . Here, "a state in which the outer package 3 is stretched in the lateral direction Y" refers only to the lateral direction Y of the outer package 3 in the unfolded and stretched state of the diaper 1. Specifically, the elastic members 33 is expanded until the design dimensions of the outer layer sheet 31 and the inner layer sheet 32 are obtained.

From the viewpoint of improving the aesthetic appearance of the diaper 1 when worn, the cross section of the diaper 1 along the lateral direction Y is shown in FIG. As viewed, it is preferable that the side edge 53S of the exterior body fixing portion 53 on the non-fixed portion 63 side is positioned further outward in the lateral direction Y than the side edge 52S of the main body fixing portion 52 on the non-fixed portion 63 side. . It is preferable that such a relationship is established in both the ventral portion F and the dorsal portion R, and as shown in FIG. It is more preferable that the above holds for M as well.

Each of the pair of sheet members 6, 6 has a non-fixed portion 63 between the main body fixing portion 52 and the exterior body fixing portion 53, as shown in FIGS. In the diaper 1 , the non-fixed portion 63 separates the main body fixed portion 52 and the exterior body fixed portion 53 . The non-fixed portion 63 extends in the longitudinal direction X and is formed over the entire length of the sheet member 6 in the longitudinal direction X. As shown in FIG. The non-fixed portion 63 is not fixed not only to the absorbent main body 2 and the outer covering 3 but also to all members constituting the diaper 1 . In the diaper 1, the absorbent main body 2 and the exterior body 3 are not directly fixed but are fixed via the sheet member 6, and the sheet member 6 is positioned between the one end portion 61 and the other end portion 62. has a non-fixed portion 63 at the . Therefore, the contraction in the lateral direction Y in the natural state of the exterior body 3 is less likely to be inhibited. As a result, chaotic wrinkling of the outer body 3 is suppressed, and deterioration of the aesthetics of the diaper 1 is suppressed. In this manner, chaotically generated wrinkles are suppressed, and the wrinkles formed over the entire exterior body 3 are substantially uniform, thereby improving the aesthetics of the diaper 1 .

As described above, in the natural state of the outer packaging 3 shown in FIGS. 3(b) and 4(b), the diaper 1 is cross-sectionally viewed along the lateral direction Y, and the unfixed portion 63 of the outer packaging fixing portion 53 is The side edge 53S of the main body fixing portion 52 on the side of the non-fixing portion 63 is positioned outward in the lateral direction Y from the side edge 52S of the non-fixing portion 63 side of the main body fixing portion 52, and the non-fixing portion of each sheet member 6 folded to protrude outward. 63 is in a relaxed state. A part of the non-fixed portion 63 of each sheet member 6 extends outward in the horizontal direction Y from the side edge of the side portion 23S along the vertical direction X of the absorber 23 . In the diaper 1, as shown in FIG. 1, a part of the non-fixed portion 63 of each sheet member 6 extends outward in the lateral direction Y from the side edge of the side portion 2S of the absorbent main body 2. 63 is in a relaxed state. Therefore, when the diaper 1 is put on, the absorbent main body 2 can easily move with the movement of the wearer, the fitting feeling of the absorbent main body 2 to the wearer can be improved, and leakage of bodily fluids can be prevented. Further, even when the looseness of the non-fixed portion 63 of the sheet member 6 is used up due to the movement of the absorbent body 2, as shown in FIG. Since the absorbent body 2 acts in the direction to fit the wearer, the fit of the absorbent main body 2 to the wearer is further improved, and leakage of bodily fluids can be prevented. Specifically, the upper diagram of FIG. 5 shows a state in which the absorbent main body 2 has moved to the right in the diagram with respect to the exterior body 3 and the slack of the non-fixed portion 63 has been used up as described above. From this state, when the absorbent main body 2 is further moved (displaced) rightward in the figure, since there is no slack in the non-fixed portion 63, the entire exterior body 3 tries to move rightward in the figure. At that time, as shown in the lower diagram of FIG. 5, a part of the exterior body 3 on the left side in the drawing is extended. A shrinkage force is generated in a part of the stretched exterior body 3, and a force acts in a direction to pull back the absorbent body 2 to the left side in the figure. In this way, the contractile force of the outer covering 3 acts in the direction of correcting the displacement of the absorbent main body 2 .
In addition, the above-mentioned "the absorbent main body 2 moves" means that the absorbent main body 2 moves relative to the outer covering 3, and depending on the usage of the diaper 1, the outer covering 3 does not move. It includes the concept that the absorbent body 2 moves to the inside, that the outer body 3 moves and the absorbent body 2 does not move, and that both the outer body 3 and the absorbent body 2 move.

The diaper 1 mentioned above can be manufactured as follows, for example.
A continuous body of the exterior body 3 and the absorbent main body 2 are manufactured in advance, and a pair of sheet members 6, 6 are prepared. 3(b) and 4(b), the unfixed portion 63 of the sheet member 6 is viewed from above with respect to the length (W23) of the absorber 23 in the horizontal direction Y in the natural state. The ratio of ((W631/W23)×100) of ((W631/W23)×100) of (W631) in the lateral direction Y (sum of the respective lateral Y intervals when a pair of non-fixed portions 63, 63 are provided) to 25% or more, Then, the joint position between the continuous body of the outer packaging 3 stretched in the conveying direction and the sheet member 6 and the joint position between the absorbent main body 2 and the sheet member 6 are adjusted so that the ratio is 200% or less. The ratio ((W631/W23)×100) is preferably 25% or more, more preferably 50% or more, and preferably 200% or less, preferably 150% or less. It is more preferably 25% or more and 200% or less, and more preferably 50% or more and 150% or less. By adjusting in this way, a part of the non-fixed portion 63 of the sheet member 6 can be extended from the side edge of the side portion 2S of the absorbent main body 2 in the natural state of the exterior body 3 .

The “interval in the lateral direction Y when the non-fixed portion 63 of the sheet member 6 is viewed in plan” means that the sheet member 6 folded so as to protrude outward is viewed in plan and the non-fixed portion 63 and the distance from the apex of the convex portion to the side edge 52S of the non-fixed portion 63 side of the main body fixing portion 52, and the distance from the apex of the convex portion to the side edge 53S of the exterior body fixed portion 53 on the non-fixed portion 63 side. means the longer interval. As described above, when a pair of non-fixed portions 63, 63 are provided, it is the total sum of the distances in the horizontal direction Y between them.
In the diaper 1, in the natural state of the outer body 3, the side edge 53S of the outer body fixing part 53 on the non-fixed part 63 side is laterally Y outside the side edge 52S of the main body fixing part 52 on the non-fixed part 63 side. located in Therefore, in the diaper 1, the "interval W631 in the lateral direction Y when the unfixed portion 63 of the sheet member 6 is viewed from above in the natural state of the outer package 3" is the unfixed distance when viewed from the absorbent main body 2 side. It is the distance from the convex apex of the portion 63 to the side edge 52S of the main body fixing portion 52 .

After fixing the absorbent main body 2 and the outer covering 3 in the stretched state via the sheet member 6 at the above-described adjustment positions, the outer covering 3 is formed into a predetermined shape in the same manner as the lateral flow manufacturing method conventionally used in the manufacture of diapers. The above-described diaper 1 can be manufactured by cutting, joining, and the like. In the diaper 1 , the sheet member 6 is joined to the outer body 3 in the stretched state, so that the outer body 3 and the sheet member 6 are joined by surface contact at the outer body fixing portion 53 . Therefore, in the natural state of the diaper, the sheet member 6 conforms to the wrinkles formed on the exterior body 3 .

Specific sizes and the like of the absorbent main body 2, the exterior body 3, and the sheet member 6 can be appropriately set based on desired values. For example, in the crotch part M (the narrowest part) in which the exterior body 3 is stretched in the lateral direction Y shown in FIG. When the unfixed portion 63 is viewed from above, the horizontal Y interval (when a pair of unfixed portions 63, 63 are provided, the sum of the respective horizontal Y intervals) (W632) ratio ((W632/W3) ×100) can be set to 10% or more and 50% or less. The ratio ((W632/W3)×100) is preferably 10% or more, more preferably 15% or more, and preferably 50% or less, and preferably 40% or less. It is more preferably 10% or more and 50% or less, and more preferably 15% or more and 40% or less.
