When using the diaper X having the above configuration, the mountain-shaped pad 30 should come into contact with the wearer's intergluteal cleft at a position and posture in which the opening 30a of the mountain-shaped pad 30 faces the wearer's anus. , Diaper X is worn by the user. Then, the stool excreted from the wearer is received by the opening 30a of the mountain-shaped pad 30 that abuts on the intergluteal cleft of the wearer, and reaches the accommodating portion 50 through the tube 40. The excreted stool will be accommodated in the accommodating portion 50 or the accommodating bag 51.

As described above, the diaper X includes a housing portion 50 located between the exterior inner seat 12 and the exterior outer seat 13 of the main body 10. Such a configuration is suitable for retaining the stool excreted from the wearer away from the wearer's body, and thus is suitable for suppressing the wearer's body from becoming contaminated with the stool. When the diaper changing work is performed with the excreted stool contained in the accommodating portion 50 for the diaper X, the body such as the operator's hand is not easily soiled.

Further, as described above, the diaper X includes a mountain-shaped pad 30 having an opening 30a which is an excretion stool receiving port and capable of contacting the wearer's intergluteal cleft. Such a configuration helps to properly receive the excreted stool from the wearer and guide it to the accommodating portion 50, and thus helps to prevent the wearer and the diaper changing worker from getting dirty with the excreted stool.

In addition, as described above, the diaper X includes a tube 40 for guiding excretory stool from the opening 30a of the mountain-shaped pad 30 to the accommodation portion 50 through the opening 12a (accommodation opening) of the outer inner sheet 12. .. The tube 40 extends from the opening 30a of the mountain-shaped pad 30 toward the accommodating portion 50. Such a tube 40 is useful for accommodating the excretory stool from the wearer in the accommodating portion 50, and the excretory stool once accommodating in the accommodating portion 50 is opened from the accommodating portion 50 to the mountain-shaped pad 30. It also helps to make it difficult to return to 30a (that is, to suppress the backflow of excreted feces). And, such suppression of backflow helps to prevent the wearer and the diaper changing worker from getting dirty with excretory stool.

Furthermore, as described above, the diaper X includes an elastic pedestal portion 60 located in the accommodating portion 50. As described above, the elastic pedestal portion 60 includes an annular base portion 61 fixed around the opening 12a of the exterior inner sheet 12, an annular base portion 62 arranged to face the annular base portion 62, and a plurality of elastic strip portions 63 bridging them.

At least a part of the tube 40 extending from the portion 30a to the accommodating portion 50 side is located in the space secured by the elastic pedestal portion 60). In the state shown in FIG. 12, the elastic strip portion 63 of the elastic pedestal portion 60 is elastically deformed, although the relative distance between the outer exterior sheet 12 and the outer exterior sheet 13 is shorter than that in the state shown in FIG. While exhibiting cushioning properties, it acts to suppress further approach between the outer exterior sheet 12 and the outer exterior sheet 13. For example, in this way, the elastic pedestal portion 60 exerts its space securing function. The configuration in which the diaper X is provided with an elastic pedestal portion 60 that has a function of securing space in the accommodating portion 50 is suitable for realizing good passage of excretory stool in the tube 40, and is also suitable for realizing a good passage of excretory stool in the accommodating portion 50. Therefore, it is suitable for suppressing the backflow of excreted stools passing through the tube 40 and the backflow of excreted stools already contained in the accommodating portion 50. Then, the suppression of these backflows helps to prevent the wearer and the diaper changing worker from getting dirty with excretory stool. The fact that the elastic pedestal portion 60 having such a function has a cushioning property is suitable for reducing the feeling of foreign matter to the wearer and ensuring a good wearing feeling in the diaper X. Further, the plurality of elastic strip portions 63 in the elastic pedestal portion 60 urge the mountain-shaped pad 30 toward the wearer's intergluteal cleft to ensure that the mountain-shaped pad 30 is in good contact with the wearer's intergluteal cleft. It also helps to make it happen.

As described above, in the diaper X, the mountain-shaped pad 30, the tube 40, the accommodating portion 50, and the elastic pedestal portion 60 cooperate with each other to suppress stains. Therefore, the diaper X is suitable for suppressing the wearer and the diaper changing worker from getting dirty with excretory stool. Such stain control helps prevent infection, which in turn helps prevent the spread of infectious diseases. The diaper X may be configured as a tape-type disposable diaper with a pair of fastening tapes, for example, worn with a diaper stopper, instead of being configured as a pants-type disposable diaper for nursing care as described above.

As described above, the chevron pad 30 has an adhesive portion 33 for sticking around the anus around the receiving opening. Such a configuration is preferable for receiving the excreted feces from the wearer by the receiving opening of the chevron pad 30, and is therefore preferable for leading to the accommodating portion 50.

As described above, the tube 40 has a plurality of cantilever pieces 43 extending in the extending direction D of the tube 40 at the end portion on the outlet opening end 42 side, and the cantilever piece 43 is on the inner wall surface side of the tube 40. Has a notch 43a extending in a direction intersecting the extending direction D. According to such a configuration, in the tube 40, when a compressing force acts on the outlet opening end 42 toward the other end side, each cantilever piece 43 tends to open outward. The fact that the cantilever piece 43 is easily deformed outward when the compressive force acts is suitable for imparting cushioning property while securing the flow path of the tube 40. The cushioning property of the tube 40 helps to reduce the feeling of foreign matter to the wearer and ensure a good wearing feeling in the diaper X. Further, the above configuration regarding the cantilever piece 43 is to achieve both compactness of the tube 40 in a state where the diaper X is folded before use and securing the length of the tube 40 when the diaper is used. Is also useful.

As described above, the tube 40 has a notch opening 44 at the end on the exit opening end 42 side. Such a configuration is suitable for securing an outlet for excreted stool from the inside to the outside of the tube 40 even when the outlet opening end 42 of the tube 40 comes into contact with the inner surface of the accommodating portion 50 or the excreted stool.

As shown in FIG. 13, the tube 40 may have a thick portion 45 at an intermediate portion in the extending direction D thereof. Such a configuration is preferred in the tube 40 for balancing net flexibility and stiffness.

The cantilever piece 43 of the tube 40 may have a tapered shape, as shown in FIGS. 14 and 15 (FIG. 15 is an enlarged perspective view showing one cantilever piece 43 having a tapered shape). .. According to such a configuration, when the outlet opening end 42 of the tube 40 receives an external force, it is suppressed that the adjacent cantilever pieces 43 are restricted from each other, and each cantilever piece 43 is easily deformed. The fact that the cantilever piece 43 is easily deformed helps to impart cushioning property to the tube 40 while securing its flow path.

As described above, the accommodating portion 50 preferably has an accommodating bag 51 arranged between the exterior inner sheet 12 and the exterior outer sheet 13 in the main body 10. In such a configuration, the excreted stool from the wearer of the diaper X is stored in the storage bag body 51. The configuration is suitable for retaining the excreted stool from the wearer at a distance from the wearer's body, and thus helps to prevent the diaper wearer and the diaper changing worker from becoming dirty with the excrement stool.

In the elastic pedestal portion 60, as described above, the annular base portion 62 has a larger outer size than the annular base portion 61, and each of the plurality of elastic strip portions 63 has a curved shape that bulges outward. Such a configuration is preferable to secure a space around the tube 40 in the accommodating portion 50 to suppress the above-mentioned regurgitation of the excreted stool, and therefore, the wearer and the diaper changing worker are prevented from being contaminated by the excreted stool. Preferred to suppress. Further, the fact that each elastic strip portion 63 has a curved shape that bulges outward is useful for the expression of cushioning property in the elastic pedestal portion 60.

In the elastic pedestal portion 60, the end portion of the elastic strip portion 63 on the annular base portion 62 side may be connected to the inner peripheral edge portion of the annular base portion 62 as shown in FIG. In such a configuration, the elastic strip portion 63 is designed to have a predetermined curved shape that exhibits good elasticity, and then the outer size of the annular base 62 is designed to be larger than the outer size of the annular base 61. Suitable. The larger the outer size of the annular base portion 62 of the elastic pedestal portion 60, the more stable the above-mentioned space securing function tends to be exhibited.
