Detailed Description of the Invention

Since the skin facing surface of the waist region disposed in the waist part of the wearer and in the vicinity thereof is always in contact with the wearer's belly and back and frequently touched with fingers, the texture is preferably good. There is room for improvement. In addition, absorbent articles such as disposable diapers can demonstrate their true value only after being worn at the correct wearing position, but they are not always worn at the correct wearing position because positioning at the time of wearing is not easy. is the current situation.

Therefore, an object of the present invention relates to providing an absorbent article that is colored, has a high designability, has a good texture on the skin facing surface, and is easy to position when worn.

Hereinafter, the present invention will be described based on preferred embodiments with reference to the drawings. 1 to 4 show a diaper 1A that is an example of a pants-type disposable diaper that is an embodiment of the absorbent article of the present invention. The diaper 1 A has a longitudinal direction X corresponding to the longitudinal direction of the wearer and a lateral direction Y perpendicular to the longitudinal direction X, and a crotch part B and a ventral side part A extending in the longitudinal direction X from the front and back of the crotch part B. And an absorptive body 23 extending in the longitudinal direction X from the abdominal side A to the back side C and capable of absorbing and holding the excreted body fluid. The crotch part B is a part disposed in the crotch part of the wearer when the diaper 1A is worn, and the abdomen part A is disposed on the abdomen side, that is, the front side of the wearer than the crotch part B when the diaper 1A is worn. The back side portion C is a portion arranged on the back side of the wearer, that is, on the back side of the crotch part B in the wearing state of the diaper 1A.

The diaper 1 A includes an absorbent main body 2 including an absorbent body 23, and an exterior body 3 disposed on a side farther from the wearer's body than the absorbent main body 2, and includes an abdominal side A and a back side C. The side edges AS and CS along the longitudinal direction X of the exterior body 3 in each are joined together by a known joining means such as an adhesive, heat seal, ultrasonic seal, etc., and as shown in FIG. Side seal portions S, S, a waist opening WH through which the wearer's torso is passed, and a pair of leg openings LH, LH through which the wearer's lower limb is passed are formed.

As shown in FIG. 2, the diaper 1 A is a front body that covers the front side (abdominal side) of the wearer's body in a wearing state with the diaper 1 A divided into the vertical direction X and the vertical center line CLx extending in the horizontal direction Y as a reference. It is divided into the back F and the back R which covers the back side (back side) of the wearer's body in the wearing state. The abdominal side A is a part of the front body F, the back side C is a part of the back body R, and the crotch B extends over the front body F and the back body R. The abdominal side part A and the back side part C are both parts that are in the same position as the side seal part S in the longitudinal direction X, and are arranged around the waist including the wearer's waist part when the diaper 1A is worn. The crotch part B is a region in which recesses for forming the leg openings LH and LH are formed at both side edges along the longitudinal direction X of the exterior body 3. The crotch part B has an excretion part facing part that is disposed to face the excretion part (penis or the like) of the wearer in the wearing state of the diaper 1A, and the excretion part facing part is usually in the longitudinal direction X of the diaper 1A. It is located at the center (on the vertical center line CLx) or in the vicinity thereof.

The absorptive main body 2 has a rectangular shape in plan view as shown by the outline in FIG. 2, extends in the longitudinal direction X from the ventral side A to the dorsal side C, and expands and extends its longitudinal direction. The diaper 1 A in the state is arranged in the center in the lateral direction Y of the exterior body 3 so as to coincide with the longitudinal direction X of the diaper 1 A, and is joined to the exterior body 3 by an adhesive.

As shown in FIG. 2, the absorbent main body 2 includes a liquid-permeable surface sheet 21 that forms a skin-facing surface, and a liquid-impermeable or liquid-permeable or water-repellent back sheet 22 that forms a non-skin-facing surface. And a liquid-retaining absorbent 23 interposed between the two

sheets

21 and 22, which are integrated by a known joining means such as an adhesive. The absorbent body 23 has a rectangular shape in plan view and forms the outer shape of the absorbent main body 2. In the plan view as shown in FIG. 2, the absorbent body 23 and the absorbent main body 2 have opposite longitudinal end edges. Yes. As the top sheet 21, the back sheet 22, and the absorber 23, various types conventionally used for this type of absorbent article can be used without particular limitation. For example, various nonwoven fabrics or apertured films can be used as the top sheet 21, and a resin film, a laminate of a resin film and a nonwoven fabric, or the like can be used as the back sheet 22. As the absorbent body 23, an aggregate of fiber materials such as pulp fibers or those having an absorbent core comprising water-absorbing polymer particles can be used, and the absorbent core has a liquid-permeable outer surface. It may be covered with a core wrap sheet.

In the present specification, the “skin facing surface” is a surface of the absorbent article or a component thereof (for example, an absorbent main body) that is directed toward the wearer's skin when the absorbent article is worn, that is, relative to the wearer's skin. The side close to the skin, and the “non-skin-facing surface” is the surface of the absorbent article or its constituent members that is directed to the side opposite to the skin side (clothing side) when the absorbent article is worn, that is, relatively worn The side far from the person's skin. In addition, "at the time of wearing" here means a state where a normal proper wearing position, that is, a correct wearing position of the absorbent article is maintained, and the absorbent article is in a state of being deviated from the wearing position. Is not included.

As shown in FIG. 2, a pair of leak-proof cuffs 24 made of a liquid-resistant or water-repellent and breathable sheet material are provided on both left and right sides along the longitudinal direction X of the skin-facing surface of the absorbent main body 2. , 24 are provided. In the vicinity of the free end of each leak-proof cuff 24, one or more elastic members 25 for forming a leak-proof cuff are arranged in an extended state. The leak-proof cuff 24 stands up at least at the crotch B when the elastic member 25 arranged in the stretched state contracts when the diaper 1A is worn, thereby causing the excretion fluid such as urine to flow outward in the lateral direction Y. To prevent.

The exterior body 3 is a main body that forms the outer shape of the diaper 1 A, and is also a main body that naturally forms the outer shapes of the abdominal side A, the crotch B, and the back side C. That is, the outer package 3 has the largest area among all the components of the diaper 1A, and forms the outer shape of the expanded and expanded diaper 1A as shown in FIG. The contour lines of the diaper 1A, that is, the contour lines of the abdominal part A, the crotch part B, and the dorsal part C are formed. The “expanded and extended state” of the diaper 1A means that the diaper 1A is separated by the side seal portion S to be in the expanded state, and the expanded diaper 1A is extended by the elastic member of each part (designed dimensions are not affected by the elastic member at all). It means a state in which it is expanded until it becomes the same size as when it is expanded in a flat state in the excluded state.

The package 3 has a rectangular shape in which the length in the lateral direction Y is longer than the longitudinal direction X in the ventral side A and the dorsal side C in a plan view in an unfolded and extended state as shown in FIG. In the crotch part B located between the side part A and the back side part C, both side edges along the longitudinal direction X of the exterior body 3, that is, the pair of leg edges LS, LS are directed toward the center in the lateral direction Y. It is curved in a convex arc shape. Since the exterior body 3 which is the main body forming the outer shape of the diaper 1A has such a plan view shape in the unfolded and extended state, the plan view shape of the diaper 1A in the same state is as shown in FIG. Furthermore, it is an hourglass shape in which the central region in the vertical direction X is bound inward in the horizontal direction Y.

As shown in FIG. 3, the outer package 3 includes an outer layer sheet 31 that forms an outer surface of the diaper 1 A, that is, a non-skin facing surface, and an inner layer sheet 32 that is disposed to face the skin facing surface 31 a of the outer layer sheet 31. It is comprised including a laminated body. That is, such a laminated body is a main body that forms the outer shape of the diaper 1A, and is also a main body that forms the outer shapes of the abdominal part A, the crotch part B, and the back side part C.

The outer layer sheet 31 is a component located farthest from the wearer's skin among all the components of the diaper 1A. The inner layer sheet 32 is positioned relatively closer to the wearer's body than the outer layer sheet 31, and forms the inner surface of the diaper 1A, that is, the skin-facing surface in the wearing state. The outer layer sheet 31 and the inner layer sheet 32 are joined by an adhesive 35 at a predetermined portion. As the outer layer sheet 31 and the inner layer sheet 32, various types conventionally used as an exterior body in this type of absorbent article can be used without any particular limitation. For example, spunbond nonwoven fabric, air-through nonwoven fabric, needle punch Nonwoven fabrics produced by various production methods such as nonwoven fabrics can be mentioned.

As shown in FIG. 1 to FIG. 3, the leg edge LS that forms the opening edge of each of the pair of leg openings LH, LH has leg elasticity for forming one or more leg gathers in the form of a thread or a band. The members 33 are arranged in an extended state, whereby an annular leg gather substantially continuous over the entire circumference is formed at the opening edge of each of the pair of leg openings LH and LH.

Further, a plurality of thread-like or belt-like waistline elastic members 34 extending in the lateral direction Y are disposed at portions of the stomach side portion A and the backside portion C that are disposed around the waist of the wearer including the waist portion. The plurality of waistline elastic members 34 are intermittently arranged at predetermined intervals in the vertical direction X. The waistline elastic member 34 extends over substantially the entire length in the lateral direction Y of the exterior body 3. As shown in FIG. 2, the abdominal part A and the dorsal part C each have a waist region D arranged around and around the wearer's waist in the wearing state of the diaper 1 A. The waistline elastic member 34 is arranged in an extended state. The waist region D is located near the waist edges AE, CE extending from the waist edges AE, CE to the longitudinal edge of the absorbent body 23 (absorbent body 2) in the ventral portion A and the back portion C, respectively. It is a waistline region (non-arrangement region of the absorbent main body 2) and usually occupies 8 to 80% of the total length in the longitudinal direction X of the ventral portion A or the dorsal portion C. The waist edge AE is an edge in the longitudinal direction X on the ventral side A side of the exterior body 3, and the waist edge CE is an edge in the longitudinal direction X on the back side C of the exterior body 3. The portion WH is defined by both end edges AE and CE. In this way, the waistline elastic member 34 is arranged in the waist region D in a state where the elastic stretchability is expressed, so that the opening edge of the waist opening WH is substantially continuous over the entire circumference. An annular waist gather is formed.

Moreover, in the diaper 1A, as shown in FIG. 2, the region where the exterior body 3 and the absorbent main body 2 (absorbent body 23) overlap in the longitudinal direction X in each of the ventral side A and the back side C, that is, Also in the region closer to the crotch B than the waist region D (region other than the waist region D), a plurality of thread-like or belt-like waistline elastic members 34 are arranged in the lateral direction Y, and the plurality of waistline elastic members are provided. 34 is intermittently arranged at predetermined intervals in the vertical direction X. The waistline elastic member 34 disposed in a region other than the waist region D crosses the absorbent main body 2. And in the arrangement | positioning area | region (area | region which overlaps with the absorptive main body 2 in planar view) in the exterior body 3, the waist elastic member 34 is divided | segmented etc., and the elasticity is inhibited, and elastic elasticity Is not arranged in a state where is expressed. Each of the

elastic members

33 and 34 is sandwiched and fixed between the outer layer sheet 31 and the inner layer sheet 32 constituting the exterior body 3 by a bonding means such as an adhesive. As each

elastic member

33 and 34, what formed elastic materials, such as natural rubber, a polyurethane-type resin, foamed urethane-type resin, and a hot-melt-type elastic member, in the shape of a thread (thread rubber) or a belt (flat rubber), is used preferably. It is done.

As shown in FIGS. 1 to 4, in the ventral side A and the back side C, the outer layer sheet 31 extends outward in the longitudinal direction X from the longitudinal edge 32E of the inner layer sheet 32 and A folded portion 310 is folded back toward the skin facing surface 32a. That is, the outer layer sheet 31 has the same shape and the same size as the inner layer sheet 32, that is, the portion constituting the main part forming the outer shape of the diaper 1A. Each of the both ends 32E, 32E in the longitudinal direction X of each of the two ends extends outward, and the extending portion is a folded portion 310. 4 shows the folded portion 310 on the abdominal side A, the folded portion 310 on the back side C is also configured in the same manner as the abdominal side A, and unless otherwise specified, the ventral portion. The description of the folded portion 310 on the A side is applied as appropriate.

The folded portion 310 of the outer layer sheet 31 disposed in the waist region D of each of the abdominal side A and the back side C is a “band-shaped skin closest sheet” that is located closest to the wearer's skin in the waist region D. Yes, the skin facing surface of the exterior body 3 (laminated body of the outer layer sheet 31 and the inner layer sheet 32), which is the main body forming the outer shape of the abdominal part A and the back part C, more specifically, the waist region D The skin facing surface 32a of the inner layer sheet 32 is arranged so as to extend in the lateral direction Y. As shown in FIG. 2, the front end of the folded portion 310, that is, the end edge 310 E in the longitudinal direction X of the folded portion 310 (the edge 310 E located on the crotch B side) is more than the absorbent main body 2 (absorber 23). It is located outside in the vertical direction X, that is, the folded portion 310 does not overlap the absorbent main body 2 (absorber 23).

Further, in the diaper 1A, as shown in FIGS. 1 to 3, the skin facing surfaces at both ends in the longitudinal direction X of the absorbent main body 2 are covered with a main body end fixing sheet 5 separate from the exterior body 3. Has been. The body end fixing sheet 5 has a rectangular shape that is long in the lateral direction Y in plan view, and a part of the waist region D and a part of the region other than the waist region D of the abdominal part A and the back part C, respectively. It is continuous over the entire length in the lateral direction Y at the close portion. The main body end fixing sheet 5 is also a “skin closest sheet” that is positioned closest to the wearer's skin, like the folded part 310, and the main part that forms the outer shape of the abdominal part A and the dorsal part C The skin facing surface, more specifically, the skin facing surface 32a of the inner layer sheet 32 in the waist region D is arranged so as to extend in the lateral direction Y while overlapping with the end portion in the longitudinal direction X of the absorbent main body 2. . In the diaper 1A, the substantially entire area of the non-skin facing surface of the main body edge fixing sheet 5 is joined to the surface facing the non-skin facing surface by an adhesive 35 such as a hot melt adhesive. The end region including the edge in the longitudinal direction X located on the crotch B side of the main body end fixing sheet 5 is fixed to a surface facing the non-skin facing surface of the main body end fixing sheet 5, It is made not to float from the surface.

By adopting the main body end fixing sheet 5, there are effects such as prevention of leakage of excretion fluid such as urine from the vertical end of the absorbent main body 2 and improvement of appearance by preventing exposure of the vertical end of the absorbent main body 2. Played. The length, that is, the width in the vertical direction X of the main body end fixing sheet 5 is not particularly limited, but is usually about 20 to 60 mm. As the main body edge fixing sheet 5, various nonwoven fabrics that can be used as the outer layer sheet 31 and the inner layer sheet 32, a film-like sheet made of a resin that can be used as a material for the nonwoven fabric, and the like can be used.

As one of the main features of the diaper 1A, as shown in FIG. 4, the non-skin facing surface 310b of the folded portion 310 (skin closest sheet) of the outer layer sheet 31 on the ventral side A faces the non-skin facing surface 310b. A non-joined portion 311 and a non-joined portion 312 with the surface to be faced (that is, the skin facing surface 32a of the inner layer sheet 32), and a colored portion 40 and a non-colored portion 41 different from the ground color of the folded portion 310. The portion 312 is located in the end region including the edge 310E in the longitudinal direction X of the folded portion 310 (the edge in the longitudinal direction X located on the crotch B side of the closest skin sheet), and the non-colored portion 41 is included.

In the form shown in FIG. 4, the entire area of the joint portion 311 in the plan view is the colored portion 40, and the entire area of the non-joint portion 312 in the plan view is the non-colored portion 41. The joint portion 311 is formed by joining the non-skin facing surface 310 b of the folded portion 310 and the skin facing surface 32 a of the inner layer sheet 32 with the adhesive 35 interposed therebetween. The folded portion 310 (skin closest sheet) of the outer layer sheet 31 of the back side portion C is also configured in the same manner as the ventral side portion A shown in FIG.

In this way, the folded portion 310 of the outer layer sheet 31 is located closest to the wearer's skin in the waist regions D of the abdominal side portion A and the back side portion C, and laterally along the waist edge edges AE, CE. In the configuration of the belt-like skin closest sheet extending in Y, the skin facing surface 310a of the folded portion 310 is always in contact with the wearer's stomach and back when the diaper 1A is worn, and for example, wearing the diaper 1A In an operation or the like, it is a part where there are relatively many opportunities to touch with fingers, and such an end region on the crotch B side of the folded portion 310 (where the edge 310E and its vicinity) is relatively frequent in contact with the skin. However, it is a non-joined portion 312 that is not joined to another member, and is a free end region that can freely contact and separate from the skin facing surface 32a of the inner layer sheet 32 that faces the non-joined portion 312. , It shall feel junction 312 is soft, thereby the texture felt by the skin about the waist region D becomes good.

Further, the folded portion 310 includes a colored portion 40 that is colored in a color different from the ground color that the folded portion 310 originally has and a non-colored portion 41 that is not colored and remains the ground color in the vertical direction X. Since the presence of the folded portion 310 stands out compared to the peripheral portion by having the side by side, the folded portion 310 can be used as a positioning mark for wearing the diaper 1A at the correct wearing position, Thereby, positioning at the time of wear can be performed easily. From the viewpoint of more reliably performing the positioning function when the absorbent article is worn by the folded portion 310 (skin closest sheet), the non-colored portion 41 is an end portion in the longitudinal direction X of the folded portion 310. Along the region, it is preferable that the folded portion 310 exists continuously over the entire length in the longitudinal direction, that is, in the lateral direction Y, that is, continuously from one side seal portion S to the other side seal portion S.

31, 32, when the diaper 1A is viewed from the outside, the colored color that is applied looks relatively dark and the design is high. . When the inner surface of the diaper 1 A, that is, the skin-facing surface is visually observed, the background color that is the end region of the folded portion 310 remains the background of the colored portion 40 of the exterior body 3. Since the non-colored portion 41 (non-joined portion 312) extends in the lateral direction Y through the waist region D, the non-colored portion 41 is noticeable due to the contrast with the colored portion 40. Therefore, the non-colored part 41 can be used as a mark at the time of positioning for wearing the diaper 1A at the correct wearing position. Further, the non-skin facing surface 31b of the outer layer sheet 31 that forms the outer surface of the diaper 1A, and the skin facing surface 310a of the folded portion 310 that forms the inner surface of the diaper 1A that can come into contact with the wearer's skin and the skin facing of the inner layer sheet 32. Since none of the surfaces 32a has the colored portion 40, the disadvantage that the printing ink constituting the colored portion 40 shifts to the wearer's skin and clothes and stains them, so-called color transfer is effectively prevented. The

The non-colored portion 41 in the folded portion 310 of the outer layer sheet 31 has a ground color that the outer layer sheet 31 originally has, but the ground color is not particularly limited, but is usually white. Not only the outer layer sheet 31 but also other constituent members of the diaper 1A, their ground color is usually white. Moreover, the color of the coloring part 40 should just be a color which can be visually distinguished from the ground color which the non-coloring part 41 exhibits, and arbitrary colors can be selected. For example, when the ground color of each constituent member of the diaper 1 A is white, red, blue, yellow, or the like can be selected as the color of the coloring portion 40. The colored portion 40 can be formed by printing the constituent members of the diaper 1A such as the outer layer sheet 31 and the inner layer sheet 32 by a known method.

By the way, in diaper 1A, when it sees along the vertical direction X, the length (length of the vertical direction X) of the non-colored part 41 which is the edge part area | region of the folding | returning part 310 of the outer layer sheet 31 is ventral side. Although it is the same in the part A and the back side part C, it replaces with this and the length of the non-colored part 41 may differ in the abdominal side part A and the back side part C. Here, “the length of the non-colored part 41 is different between the ventral part A and the dorsal part C” includes not only the form in which both the ventral part A and the dorsal part C have the non-colored part 41. In addition, a mode in which only one of the ventral portion A and the back portion C has the non-colored portion 41 and the other has no non-colored portion is also included. Such a configuration makes it easier to distinguish between the abdominal part A and the dorsal part C, so that inconveniences such as wearing the front and back of the diaper 1A by mistake are effectively prevented. About the length of the vertical direction X of the non-coloring part 41, the ventral part A may be lengthened compared with the back part C, and vice versa.

Hereinafter, another embodiment of the present invention will be described with reference to FIGS. In other embodiments to be described later, constituent parts different from the diaper 1A described above will be mainly described, and the same constituent parts will be denoted by the same reference numerals and description thereof will be omitted. The explanation about the diaper 1 A is appropriately applied to components that are not particularly described.

In the diaper 1B shown in FIG. 5, the longitudinal edge 32E of the inner layer sheet 32 is located closer to the crotch B than the edge 310E of the folded portion 310 of the outer layer sheet 31, and the folded portion 310 is the inner layer sheet. The outer layer sheet 31 is bonded to the opposite outer layer sheet 31 via an adhesive 35 without overlapping with the outer layer 32.
