  Conventionally, the stool excreted from the wearer of the disposable diaper is received inside the wearer's body side of the diaper, and all or most of it is retained between the wearer's body and the diaper. The wearer's body becomes dirty by this excremented stool. In addition, at the time of work of changing diapers after excretion, the body such as the hands of the worker may be stained by excrement kept in the diaper.

  The present invention has been conceived under the circumstances as described above, and the object thereof is to provide a disposable diaper suitable for preventing a wearer or diaper changer from being stained with excrement. It is to do.

  The disposable diaper provided by the first aspect of the present invention comprises a main body portion, a torso tear opposing portion, an accommodation portion, and a feeding passage. The body portion has a multilayer configuration including an exterior inner sheet and an exterior outer sheet. The exterior inner sheet is positioned on the inner side of the diaper than the outer exterior sheet. The heel and tear opposing portion is capable of abutting on the wearer's heel and tear area and has a tip opening for receiving feces. The accommodating part is for separating the wearer's body and accommodating excremented stool, and is located between the exterior inner sheet and the exterior outer sheet. The feeding passage is for guiding excremented stool from the tip opening of the torso-facing portion to the storage portion, and has an open end facing the storage portion. The open end has one or more slits or notches extending from the open end side. In addition, the feed passage is, for example, a flexible passage made of a flexible material such as a resin film. The disposable diaper with such a configuration is worn by the user such that the torso opposing portion abuts on the torso of the wearer at a position and posture where the tip opening of the torso opposing portion opposes the wearer's anus Be done. In addition, the disposable diaper of the present invention may be configured as a pants type, may be configured as a so-called tape type, or may be configured as a type that is used in both of these types. It may be.

  The stool excreted from the wearer of such disposable diapers is received by the tip opening of the palpebral opposite part which abuts on the wearer's palpebral part, and reaches the receptacle of the excrement through the feeding duct. sell. The above configuration that the diaper includes the excrement storage portion between the exterior inner sheet and the exterior outer sheet of the main body is suitable for holding the excrement from the wearer separated from the wearer's body, Therefore, it is suitable for preventing the wearer or the body from being stained with feces. And about this diaper, when a diaper change operation is performed in the state in which the excretion stool was accommodated in the accommodating part, bodies, such as a worker's hand, are hard to become dirty.

  Moreover, the above-described configuration in which the diaper has a tip opening that is an excrement opening and is capable of coming into contact with the wearer's cleft portion is such that the excrement from the wearer is guided to the storage portion. In addition, it contributes to control that a wearer and a diaper change worker are soiled with excrement.

  In addition, the above configuration that the open end facing the housing in the feeding duct has a slit extending from the opening end side is suitable for suppressing the backflow of feces from the housing to the feeding duct. . The open end of the feeding duct is made of a flexible material and has a slit that is a slit, so that the shape is difficult to maintain. Such an open end is easy to open and allow the passage of excrement passing through the feeding duct toward the storage portion, but is difficult to open when it receives an external contact action. . Therefore, it is difficult for excremented stool to enter from the storage section outside the opening end with respect to the opening end of the feeding pipeline. It is difficult for the excremented stool once stored in the storage section to flow back into the feeding duct via the low shape-retaining open end. Such a configuration suitable for suppressing the backflow of excremented stool from the containing portion to the feeding duct is suitable for maintaining the accommodated state of the excremented stool contained in the containing portion, and hence wearing Helping to prevent people and diaper changing workers from getting dirty with stools.

  As mentioned above, the disposable diaper which concerns on the 1st side of this invention is suitable for suppressing that a wearer and a diaper change worker are soiled with excretory stool.

  In the disposable diaper according to the first aspect of the present invention, preferably, the torso-facing portion has a rear end opening or a proximal end opening larger than the opening on the side opposite to the distal end opening, The feeding line extends through the proximal opening to the storage side. According to such a configuration, when the feeding pipeline is the above-mentioned flexible pipeline, the end on the side of the storage section rather than the end (starting end) on the side of the distal end opening of the tear-off facing portion in the flexible pipeline End) is easy to take the lower position. It is preferable that the end of the feeding line can be easily positioned lower than the starting point in order to suppress the backflow of feces in the feeding line.

  A disposable diaper provided by the second aspect of the present invention comprises a main body, a torso crusher, a container, and at least one on-off valve membrane. The body portion has a multilayer configuration including an exterior inner sheet and an exterior outer sheet. The exterior inner sheet is positioned on the inner side of the diaper than the outer exterior sheet. The heel and tear opposing portion is capable of abutting on the heel and tear of the wearer, and has a distal end opening for receiving excremented stool and a proximal end opening located on the opposite side. The accommodating part is for separating the wearer's body and accommodating excremented stool, and is located between the exterior inner sheet and the exterior outer sheet. The feeding passage is for guiding excremented stool from the tip opening of the toe facing portion to the containing portion, and is, for example, a flexible passage made of a flexible material such as a resin film. The on-off valve film is an element disposed opposite to the proximal end opening side in the torso facing portion, and is deformable in an open state in which the proximal end opening is communicated with the housing. Each on-off valve membrane has, for example, a tongue shape. In the case where a plurality of on-off valve membranes are disposed opposite to the proximal end opening of the torso-facing portion, each on-off valve membrane is disposed on its free end side to have a region that can overlap with other on-off valve membranes. preferable. The disposable diaper with such a configuration is worn by the user such that the torso opposing portion abuts on the torso of the wearer at a position and posture where the tip opening of the torso opposing portion opposes the wearer's anus Be done. In addition, the disposable diaper of the present invention may be configured as a pants type, may be configured as a so-called tape type, or may be configured as a type that is used in both of these types. It may be.

  The stool excreted from the wearer of such disposable diapers is received by the tip opening of the palpebral opposite part which abuts on the wearer's palpebral part, and reaches the receptacle of the excrement through the feeding duct. sell. The above configuration that the diaper includes the excrement storage portion between the exterior inner sheet and the exterior outer sheet of the main body is suitable for holding the excrement from the wearer separated from the wearer's body, Therefore, it is suitable for preventing the wearer or the body from being stained with feces. And about this diaper, when a diaper change operation is performed in the state in which the excretion stool was accommodated in the accommodating part, bodies, such as a worker's hand, are hard to become dirty.

  Moreover, the above-described configuration in which the diaper has a tip opening that is an excrement opening and is capable of coming into contact with the wearer's cleft portion is such that the excrement from the wearer is guided to the storage portion. In addition, it contributes to control that a wearer and a diaper change worker are soiled with excrement.

  In addition, the present diaper is provided with an on-off valve film disposed opposite to the proximal end opening in the hemorrhoid facing portion and deformable in an open state in which the proximal end is communicated with the accommodating portion. Is suitable for suppressing backflow of excremented stool from the containing portion to the tip opening side of the torso-facing portion (that is, the inside of the diaper body on the wearer's body). The on-off valve membrane disposed opposite to the proximal end opening side in the tear-off facing portion in such a manner as to divide between the proximal end opening portion of the tear-off facing portion and the accommodation portion When the feces received through the opening passes through the proximal opening and the on-off valve membrane, it tends to deform and permit its passage. On the other hand, the on-off valve film is unlikely to be deformed to an open state in which the proximal end opening portion and the storage portion are communicated with each other depending on the contact action from the storage portion side. This is because the wall part around the proximal end opening in the sputum facing part abuts on the on-off valve membrane and can exert an action to prevent such deformation of the on-off valve membrane due to the contact action from the housing side. Therefore, it is difficult for excremented stool to enter from the side of the storage part with respect to the proximal end opening part of the hemorrhoid facing part. It is difficult for the excremented stool once stored in the storage portion to flow back to the proximal end opening portion in the sputum-facing portion and further to the distal end opening side. Such a configuration suitable for suppressing backflow of excremented stool is suitable for maintaining the accommodation state of excremented stool accommodated in the accommodating portion, and thus, the wearer and the diaper changing worker excrete excremented stool Helps to control contamination.

  As mentioned above, the disposable diaper which concerns on the 2nd side of this invention is suitable for suppressing that a wearer and a diaper change worker are soiled with excrement.

  In the first and second aspects of the present invention, the groin opposite portion preferably has an adhesive portion around the tip opening for sticking around the anus. Such a configuration is suitable for receiving excremented stool from the wearer by means of the tip opening of the heel and thus is suitable for guiding it into the receptacle.

  Preferably, the armored inner sheet has an assembly opening, and the torso opposite portion is assembled to the armored inner sheet at the assembly opening through a stretchable elastic material. The stretchable material is, for example, a string-like rubber material or a stretchable sheet material. According to such a configuration, when the disposable diaper of the present invention is worn, a good contact state or close contact state of the tear-off portion against the tear-off portion of the wearer is realized using the biasing force due to the stretchable material. It is easy and therefore easy to receive excrement from the wearer by the tip opening of the palpebral opposite part.

  When the stretchable sheet material is adopted as the stretchable material, preferably, the stretchable sheet material and the crease-tearing portion close the assembly opening of the exterior inner sheet. Such a configuration is suitable for keeping excremented stool from the wearer separated from the wearer's body in the containing section, and thus to prevent the wearer and the diaper changing worker from being stained with excremented stool. To contribute.

  The torso facing portion preferably includes a tip top side formed with the tip opening and a pair of inclined surface parts connected via the tip top side. The toe-to-tear portion with such a configuration is likely to abut against the toe-tear portion that is recessed in the wearer's body, with the tip opening facing to the wearer's anus. Therefore, the toe-to-tear portion with such a configuration tends to receive feces from the wearer at its tip opening.

  Preferably, the pair of inclined surface portions in the heel and tear opposing portion are configured to be openable and closable. That is, it is possible to perform both an open leg movement in which the opening angle of a pair of inclined surface portions connected via the tip top side portion increases in the groin opposite portion and a closed leg movement in which the open angle decreases after the open leg. Preferably, the pair of inclined surface portions is configured. In such a torso facing portion, as the pair of inclined surface portions is opened, that is, as the opening angle of the pair of inclined surface portions is increased, the opening size of the tip opening opened at the top end of the tip is increased. There is a tendency. In the case where such a torso facing portion is assembled to the exterior inner sheet via the elastic member at the assembly opening of the exterior inner sheet, the stool which is being excreted from the anus of the wearer torso portion is torn. When a pressing action is exerted on the tip top side or tip opening of the facing portion, the pair of inclined surface portions in the crease opposite portion assembled to the exterior inner sheet through the stretchable member opens and tip opening The opening size of the part is increased, thus facilitating the acceptance of feces at the opening.

  The storage portion preferably includes a storage bag disposed between the exterior inner sheet and the exterior outer sheet in the main body. In such a configuration, excremented stools from the wearer of the diaper will be contained in the containing bag. The configuration is suitable for retaining excremented stool from the wearer in a state of being separated from the wearer's body, and thus helps to prevent diaper wearers and diaper changing workers from being stained with excrement.

  It is preferable that the main-body part in the disposable diaper of this invention has a multilayer structure further including a top sheet with the above-mentioned exterior inner sheet and exterior outer sheet. In the multi-layer configuration, the top sheet is located on the inner side of the diaper, that is, on the wearer side of the two exterior sheets. And it is preferable that this diaper further equips the top sheet and the exterior inside sheet with an absorption unit which has a function of absorbing excrement such as excrement.

Each on-off valve film 60 has, for example, a tongue shape. Examples of the constituent material of the on-off valve film 60 include resin films such as flexible plastic films, and flexible paper materials.

  The on-off valve film 60 may be disposed to face the opening 30 b (proximal end opening) side of the mountain-shaped pad 30 in the mode shown in FIG. 11 instead of the mode shown in FIG. 10. 11 (a) and 11 (b) are respectively a cross-sectional view of the mountain-shaped pad 30 provided in the diaper X2 and the vicinity thereof, and FIGS. 7 (a) and 7 (b) for the diaper X1 described above. Corresponds to the cross-sectional view of FIG. Also in the embodiment shown in FIG. 11, as in the embodiment shown in FIG. 10, each on-off valve film 60 is joined to the stretchable member 14 so that the two on-off valve films 60 can cooperate to close the opening 30b. .

  About each composition of body part 10, absorption unit 20, mountain type pad 30, and seat part 50 in diaper X2, body part 10 mentioned above about diaper X1, absorption unit 20, mountain shaped pad 30, and seat part 50 It is similar to the configuration.

  When using the diaper X2 having the above configuration, the mountain-shaped pad 30 abuts on the wearer's groin in a position / posture in which the opening 30a of the mountain-shaped pad 30 faces the wearer's anus , Diapers X2 are worn by the user. Then, the stool excreted from the wearer can be received by the opening 30 a of the mountain-shaped pad 30 in contact with the groin of the wearer, pass through the mountain-shaped pad 30, and reach the housing 50. The excremented stool is contained in the containing bag 51.

  The configuration in which the diaper X2 includes the excrement storage portion 50 between the exterior inner sheet 12 and the exterior outer sheet 13 of the main body portion 10 keeps the excrement from the wearer separated from the wearer's body And therefore suitable for controlling the wearing of the wearer or his / her body by stool. Then, when the diaper changing operation is performed with the excremented stool being stored in the storage unit 50, the body such as the hands of the worker is not easily soiled.

  In addition, the diaper X2 has an opening 30a, which is an excrement opening, and is provided with a mountain-shaped pad 30 that can be in contact with the wearer's cleft, and leads excrement from the wearer to the storage unit 50. In addition, it contributes to control that a wearer and a diaper change worker are soiled with excrement.

  In addition, the opening 30b (proximal end opening) side of the mountain-shaped pad 30 is disposed opposite to the opening 30b, and the opening 30b is communicated with the storage unit 50 so that it is deformed due to the weight of excreted stool etc. The above-described configuration in which the diaper X2 includes the on-off valve film 60 that is possible is suitable for suppressing the backflow of excremented stool from the accommodation unit 50 to the opening 30a (tip opening) side of the chevron pad 30. The on-off valve film 60 disposed opposite to the opening 30 b side of the mountain-shaped pad 30 in such a manner as to divide between the opening 30 b of the mountain-shaped pad 30 and the housing 50 is the opening in the mountain-shaped pad 30 When feces received through 30a pass through the opening 30b and the on-off valve membrane 60, they are deformed and easy to allow the passage. On the other hand, the on-off valve film 60 is unlikely to be deformed to an open state in which the opening 30 b communicates with the housing 50 depending on the contact action from the housing 50 side. This is because the wall portion around the opening 30b in the chevron pad 30 can abut against the on-off valve film 60 to exert an action to prevent such deformation of the on-off valve film 60 by the contact action from the accommodation portion 50 side. . Therefore, it is difficult for excremented stool to enter the opening 30 b of the mountain-shaped pad 30 from the side of the storage unit 50. It is difficult for the excremented stool once stored in the storage portion 50 to flow back to the opening 30b of the mountain-shaped pad 30 and further to the opening 30a. Such a configuration suitable for suppressing backflow of excremented stool is suitable for maintaining the accommodation state of excremented stool stored in the storage unit 50, and thus, the wearer and the diaper changing worker excrete Helps to control fouling in stools.

  As described above, the diaper X2 is suitable for preventing the wearer and the diaper changing worker from being soiled by excrement. Such a diaper X2 may be configured as an infant diaper or as an adult diaper. Further, the diaper X2 may be configured as a tape-type disposable diaper with a pair of fastening tapes, for example, as a diaper closure, instead of being configured as a pants-type disposable diaper as described above.
