The diaper 10 in the present embodiment is a deployable disposable diaper, and includes a front body region 10F, a back body region 10R, and a crotch region 10C that connects the front body region 10F and the back body region 10R. Moreover, the waist periphery opening part 10W which surrounds a wearer's waist part with the front body area | region 10F and the back body area | region 10R at the time of wear is formed. Similarly, a pair of left and right leg openings 10L that surround the thigh portions of both legs of the wearer are formed by the lower end crotch region 10C of the front body region 10F and the back body region 10R.

  FIG. 2 shows a perspective view of the unfolded disposable diaper shown in FIG. 1 viewed from the back side. FIG. 2 shows a lower half of the unfolded disposable diaper as seen from the back side when the infant wears it. As shown in FIG. 2, the front body region 10F is positioned on the wearer's ventral side and the back body region 10R is positioned on the wearer's back side when worn. The crotch region 10 </ b> C covers the wearer's crotch, and the leg of the wearer is passed through the pair of left and right leg openings 10 </ b> L. Therefore, the leg periphery opening 10L is located at any position around the thigh from the base of the wearer's legs.

  The imaginary line P extends through the crotch part from the abdomen side to the back side in the central part of the diaper. Specifically, for example, if the imaginary line P is defined with the waist side of the diaper as the upper side and the crotch side as the lower side, the phantom line P extends along the diaper surface and in the vertical direction, and passes through the crotch part on the back side. Also extends in the vertical direction.

  The left and right end edges of the back body region 10R of the cover sheet 11 positioned outside the diaper 10 are overlapped with the left and right end edges of the front body region 10F when worn, and are connected to form a leg opening 10L. A pair of left and right fastening tapes 10A to be obtained are joined. The fastening tape 10A is bonded to the front patch sheet 10B bonded on the cover sheet 11 in the front body region 10F so as to be repeatedly peelable. In addition, an elastic sheet 10D that extends along the width direction of the cover sheet 11 and that gives the wearer an appropriate wearing feeling around the waist is provided in an area corresponding to the upper end of the back body area 10R. It has been. The lower body wearing a diaper in FIG. 2 shows a standing state, but this embodiment is not intended only for walking in a standing manner. It exerts its effects on various body posture changes such as general anteroposterior movement, prone position, and supine position.

  FIG. 3 is a perspective view showing the unfolded disposable diaper shown in FIG. 1 in an exploded state. As shown in FIG. 3, the diaper 10 according to the present embodiment includes, in order from the outside, a cover sheet 11 formed of a thin nonwoven fabric in order to obtain a good touch, and a back sheet (back sheet) having liquid impermeability. 12, an absorbent body 13, a liquid-permeable top sheet (surface sheet) 14 provided with ridges 19 </ b> A and 19 </ b> B including ridges that are barrier members, and a side sheet 15 for forming a three-dimensional gather. It has a laminated structure in which the layers are joined one after another. About the absorber 13 of FIG. 3, the state which fractured | ruptured partially is shown for convenience of explanation. On the left and right sides of the crotch region 10C of the cover sheet 11, a pair of cutout portions 11A each having a semicircular arc shape serving as a leg opening 10L is formed. In addition, a pair of notches 15A each having a semicircular arc shape is formed on both the left and right sides of the crotch region 10C of the side seat 15 in the same manner as the cover seat 11. The back sheet 12 is joined to the cover sheet 11, and the previous absorber 13 is arranged between the back sheet 12 and the top sheet 14, and the top sheet 14 is joined to the back sheet 12 through the absorber 13. Is done. Further, an elastic sheet 10D is joined to a region of the back sheet 12 corresponding to the upper end portion of the back body region 10R. Between the cover sheet 11 and the side sheet 15, thread rubber 16 for forming a leg gather is joined in an extended state. The collars 19A and 19B provided on the top sheet 14 function as a barrier for blocking body fluid and watery stool.

  The absorbent body 13 of the present embodiment located under the top sheet 14 includes an absorbent main body 17 mainly composed of pulp and a super absorbent polymer (hereinafter also referred to as “SAP”), tissue, nonwoven fabric, and the like. It is wrapped with a covering member 18 such as a core wrap composed of The seam formed by wrapping the absorbent main body 17 with the covering member 18 is formed so as to extend in the longitudinal direction on the upper surface of the absorbent body 13, for example, as shown in FIG. 3. The absorbent body 13 of the present embodiment has an elongated shape so as to extend from the front body, the crotch, and the back body, and is divided into a front body part, a crotch part, and a back body part. Here, assuming that the front body part to the back body part are the front and back (up and down) directions, and the direction orthogonal to the front and back parts is the left and right direction, the absorbent body 13 of the present embodiment is a rectangular thing with different front and rear (up and down) left and right length (In FIG. 3, the front and rear (up and down) lengths are longer than the left and right lengths). In addition, the shape of the absorber 13 of this embodiment is not restricted to this, For example, the substantially square thing of the front and back (upper and lower) left and right length is comparable, and a notch part is provided in both sides, and the width | variety of a center part is sufficient. It includes various shapes such as an hourglass type that is narrower than the front and rear ends, one that has rounded corners at the front and rear (up and down) ends, an elliptical shape that extends front and rear (up and down), and a circular shape. Moreover, a pair of left and right leg openings 10L surrounding the crotch portion of both legs may be formed in the crotch portion of the absorbent body 13 so as to form a pair of notches that form an arc shape. In order to give a liquid diffusion function to the surface of the absorber 13 of this embodiment, you may provide uneven | corrugated | grooved parts, such as embossing.

  The surface of the liquid-permeable top sheet 14 in the present embodiment is provided with collars 19A and 19B in order to dam body fluid and watery stool. The buttocks 19A and 19B are regions other than the region corresponding to the crotch region 10C in the region of the top sheet 14 and the region corresponding to the front body region 10F and / or the back body region 10R. It is provided extending in the direction. Specifically, a collar portion 19A is provided in a region (first region) of the top sheet 14 corresponding to the rear body region 10R of the diaper 10, and a region (second region) of the top sheet 14 corresponding to the front body region 10F. ) Is provided with a flange 19B. The base end portion of each heel of the heel portions 19A and 19B is fixed to the surface of the top sheet 14, and the edge of the tip portion of each heel is a free end. Further, the heel portions 19A and 19B are oriented so that the edges thereof face the crotch region 10C.

  In the present embodiment, because of the liquid diffusion in the crotch region 10C, the surface of the top sheet 14 corresponding to the crotch region 10C of the diaper 10 is not provided with a buttock. When the body fluid is diffused widely on the surface of the top sheet 14, the region absorbed by the absorber 13 is expanded correspondingly, and the body fluid can be absorbed quickly and in large quantities by the absorber 13.

  In this embodiment, the body fluid is diffused in the crotch region 10C in this way, and the absorbent body 13 is encouraged to absorb in a wide area, while the body fluid that has not been absorbed is blocked by the buttocks 19A and 19B. By making it absorb in the absorber 13, it becomes possible to suppress that a bodily fluid leaks out of the diaper 10, making the absorber 13 absorb a bodily fluid efficiently. That is, the bodily fluid that has not been absorbed is blocked by the heel portions 19A and 19B, and is absorbed by the capillary 13 generated by the gap between the surface of the heel on the crotch region 10C side and the surface of the top sheet 14. Be guided to. When the body fluid reaches the absorber 13, since the absorber 13 generally has a strong capillary force, the induction of the body fluid is promoted and the prevention of leakage of the body fluid can be enhanced.

  As for the watery stool, as in the case of the body fluid, those that are diffused in the crotch region 10C and cannot be absorbed can be dammed by the buttocks 19A and 19B. The dammed watery stool is guided toward the base end of the collars 19A and 19B, and its liquid component is absorbed by the absorber 13, while its solid component loses its fluidity and remains in place. become. Therefore, the solid content of the watery stool can be captured by being sandwiched between the surface located in the crotch region 10C and the surface of the top sheet 14 among the folded portions of the heel portions 19A and 19B. Therefore, it is possible to suppress leakage of watery stool from the diaper 10 as well as body fluid. And since the solid content of the captured watery stool is covered by the buttock portions 19A and 19B, the opportunity for the solid content of the watery stool to directly touch the wearer's skin is reduced, and the wearing feeling is improved. It is possible to make it less likely to cause rash.

  The heel portions 19A and 19B may be able to stand, and by inclining the heel portions 19A and 19B so that the edges thereof face the crotch region 10C, a space is formed between the top sheet 14 and the space. It becomes possible to further easily capture the solid content of the watery stool. The formation of this space can be realized, for example, by fixing both ends of the flange portions 19A and 19B to the side sheet 15.

  A liquid-impermeable side sheet 15 is joined to the left and right side edges of the top sheet 14, and a rubber thread 20 for forming a three-dimensional gather is stretched on the inner edges of the left and right side sheets 15. It is joined. In addition, in order to give a liquid diffusion function, you may provide uneven | corrugated | grooved parts, such as embossing, on the surface of the top sheet 14 corresponding to the crotch region 10C.

  FIG. 4 is a top view of the laminated structure of the side sheet 15, the top sheet, and the absorber 13 of the diaper 10 according to the first embodiment of the present invention viewed from the top sheet side, and FIG. FIG. 4 (b) shows a state in which the buttock is provided only on the back body side, and FIG. 4 (c) shows a state in which the buttock is provided on the front body side and the back body side. The state where the collar part was provided only on the side is shown. For simplification of description, the structure shown in FIGS. 4A to 4C is assumed to be composed of four bodies, that is, the back sheet 12, the absorber 13, the top sheet, and the side sheet 15. The absorber 13 is indicated by a broken line in the figure.

  As shown in FIG. 4A, a plurality (four in the illustrated example) of the heel portion 19A on the back body side has an interval (first interval) L1 in the longitudinal direction of the top sheet 14. The three heels of the heel portion 19B on the front body side are also provided so that the interval (second interval) is L2 in the longitudinal direction of the top sheet 14. In the present embodiment, the interval L1 is smaller than the interval L2, and the number of ridges in the flange portion 19A is larger than the number of ridges in the flange portion 19B. In this embodiment, the intervals at which the folds are formed are equal, but the folds are not provided at regular intervals as long as they meet the object of the present invention to enhance the prevention of leakage of bodily fluids and watery stools. May be.

  In the present embodiment, the bodily fluid or watery stool liquid that could not be absorbed in the crotch region is gradually dammed up by a plurality of heels of the heel parts 19A and 19B and absorbed by the absorbent body directly below, The solid content is guided to the base end side of the flanges 19A and 19B to be captured. With this configuration, body fluid and watery stool are prevented from leaking from the ventral side and / or the back side of the diaper 10.

  In general, since the back of the wearer is flatter than the abdomen, there is a possibility that a gap with the diaper is easily formed, and bodily fluids and watery feces that cannot be absorbed by the absorbent body 13 may leak from the gap. is there. Therefore, in the present embodiment, leakage prevention of bodily fluids and watery stools from the back side is enhanced by providing heels closer to the back body side of the top sheet 14 than the front body side.

  As a modification of the present embodiment, a configuration is provided in which a buttock is provided only on the back body side like a top sheet 14A shown in FIG. 4B, or on the front body side like a top sheet 14B shown in FIG. Alternatively, a configuration may be adopted in which a collar portion is provided only on the surface. That is, as long as the intended purpose of enhancing the prevention of leakage of bodily fluids and watery stools can be achieved, the buttocks may be provided on either the back body side or the front body side.
