Conventionally, feces excreted from a wearer of a disposable diaper are received inside the wearer's body side of the diaper, and all or most of them are retained between the wearer's body and the diaper. The body of the wearer becomes dirty due to the excreted feces that are retained. In addition, during the work of changing diapers after excretion, the body such as the hand of the operator may be contaminated by excretion stools retained in the diaper.

The present invention has been devised under the circumstances as described above, and an object thereof is to provide a disposable diaper suitable for suppressing a wearer or a diaper changing worker from being soiled by excrement. To do.

The disposable diaper provided by the first aspect of the present invention includes a main body portion, a gluteal cleft opposing portion, a housing portion, and a stool conduit. The body portion has a multilayer structure including an exterior inner sheet and an exterior outer sheet. The exterior inner sheet is located on the inner side of the diaper than the exterior outer sheet. The gluteal cleft opposing part is capable of contacting the gluteal cleft of the wearer and has a tip opening for receiving excrement. The accommodating part is for accommodating excrement and feces apart from the wearer's body, and is located between the exterior inner sheet and the exterior outer sheet. The bladder duct is for guiding excrement and feces from the tip end opening of the gluteal cleft facing portion to the accommodating portion, and has an open end facing the accommodating portion. The open end has one or more slits or cuts extending from the open end side. Further, the flight conduit is a flexible conduit made of a flexible material such as a resin film. The disposable diaper having such a configuration is worn by the user so that the gluteal cleft is in contact with the gluteal cleft of the wearer at a position and posture in which the tip opening of the cleft cleft is facing the wearer's anus. To be done. Further, 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 for both types. It may be.

The feces excreted from the wearer of such disposable diaper are received in the tip opening of the cleft opposition part that abuts the gluteal cleft of the wearer, and reaches the accommodating part of the excrement through the stool duct. sell. The above-mentioned configuration in which the diaper is provided with a storage portion for excrement between the exterior inner sheet and the exterior outer sheet of the main body portion is suitable for retaining excrement from the wearer in a state of being separated from the wearer's body, Therefore, it is suitable for suppressing the wearer or the body thereof from becoming soiled with excrement. When the diaper changing operation is performed on the present diaper while the feces are accommodated in the accommodating portion, the hands and the body of the worker are not easily soiled.

In addition, the above-described configuration in which the diaper is provided with a gluteal cleft opposing portion that has a tip opening that is a fecal receiving port and can contact the gluteal cleft of the wearer leads the fecal excretion from the wearer to the accommodating portion. In addition, it contributes to suppressing the wearer and the diaper change worker from being soiled by excrement.

In addition, the above-described configuration in which the opening end portion facing the accommodation portion in the stool conduit has the slit extending from the opening end side is suitable for suppressing the backflow of excrement and feces from the accommodation portion to the stool conduit. .. Since the open end of the stool conduit is made of a flexible material and has slits that are slits, it is difficult to maintain its shape. Such an open end portion is opened to easily allow passage of excretory stool moving in the stool duct toward the accommodation portion, but is difficult to open when a contact action from the outside is received. .. Therefore, it is difficult for feces to enter the opening end portion of the stool conduit from the accommodation portion outside the opening end portion. It is difficult for the excreted feces once stored in the storage portion to flow back into the stool conduit via the open end having a low shape-retaining property. Such a configuration, which is suitable for suppressing the backflow of the excrement feces from the accommodation part to the stool duct, is suitable for maintaining the accommodation state of the excretion feces accommodated in the accommodation part, and by extension, is worn. It helps to prevent the person and diaper change worker from getting dirty with excrement.

As described above, the disposable diaper according to the first aspect of the present invention is suitable for suppressing the wearer and the diaper changing operator from getting soiled with excrement.

In the disposable diaper according to the first aspect of the present invention, preferably, the gluteal cleft opposing portion has a rear end opening or a proximal end opening larger than the opening on the side opposite to the tip opening. The flight conduit extends through the base end opening toward the accommodation portion. According to such a configuration, in the case where the stool conduit is the above-mentioned flexible conduit, the end (starting end) closer to the accommodating portion than the end (starting end) on the tip opening side of the gluteal cleft facing portion of the flexible conduit ( It is easy for the end point) to take the lower position. It is preferable that the terminal end of the excretory duct is more likely to be located below the starting end in order to suppress the backflow of excrement in the excretory duct.

The disposable diaper provided by the 2nd side surface of this invention is equipped with a main-body part, a cleft cleft opposition part, a storage part, and at least 1 on-off valve membrane. The body portion has a multilayer structure including an exterior inner sheet and an exterior outer sheet. The exterior inner sheet is located on the inner side of the diaper than the exterior outer sheet. The gluteal cleft opposing part is capable of contacting the gluteal cleft of the wearer and has a distal end opening for receiving excretion and a proximal end opening located on the opposite side. The accommodating part is for accommodating excrement and feces apart from the wearer's body, and is located between the exterior inner sheet and the exterior outer sheet. The stool delivery conduit is for guiding the excretion stool from the tip end opening of the gluteal cleft facing portion to the accommodating portion, and is a flexible conduit made of a flexible material such as a resin film. The on-off valve membrane is an element that is arranged so as to face the proximal end opening side of the gluteal cleft facing portion, and can be deformed into an open state that allows the proximal end opening portion to communicate with the housing portion. Each on-off valve membrane has, for example, a tongue shape. When a plurality of on-off valve membranes are arranged so as to face the proximal end opening of the gluteal cleft facing portion, each on-off valve membrane is arranged so as to have a region on its free end side that may overlap with another on-off valve membrane. preferable. The disposable diaper having such a configuration is worn by the user so that the gluteal cleft is in contact with the gluteal cleft of the wearer at a position and posture in which the tip opening of the cleft cleft is facing the wearer's anus. To be done. Further, 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 for both types. It may be.

The feces excreted from the wearer of such disposable diaper are received in the tip opening of the cleft opposition part that abuts the gluteal cleft of the wearer, and reaches the accommodating part of the excrement through the stool duct. sell. The above-mentioned configuration in which the diaper is provided with a storage portion for excrement between the exterior inner sheet and the exterior outer sheet of the main body portion is suitable for retaining excrement from the wearer in a state of being separated from the wearer's body, Therefore, it is suitable for suppressing the wearer or the body thereof from becoming soiled with excrement. When the diaper changing operation is performed on the present diaper while the feces are accommodated in the accommodating portion, the hands and the body of the worker are not easily soiled.

In addition, the above-described configuration in which the diaper is provided with a gluteal cleft opposing portion that has a tip opening that is a fecal receiving port and can contact the gluteal cleft of the wearer leads the fecal excretion from the wearer to the accommodating portion. In addition, it contributes to suppressing the wearer and the diaper change worker from being soiled by excrement.

In addition, the present diaper has the above-described configuration in which the diaper is provided with an on-off valve membrane that is arranged to face the proximal end opening side of the buttocks cleft facing portion and that can be deformed into an open state that communicates the proximal end opening portion with the housing portion. Is suitable for suppressing backflow of feces from the accommodating portion to the tip opening side of the crotch opposition portion (that is, inside the wearer's body side of the diaper). The on-off valve membrane arranged facing the proximal end opening side of the gluteal cleft facing portion in such a manner as to partition the proximal end opening of the gluteal cleft facing portion and the accommodating portion has a tip in the cleft cleft facing portion. When excreted feces received through the opening pass through the proximal opening and the on-off valve membrane, they are easily deformed to allow the passage. On the other hand, the on-off valve membrane is unlikely to be deformed by the contact action from the housing portion side to an open state in which the base end opening portion and the housing portion communicate with each other. This is because the wall portion around the proximal end opening in the buttocks cleft facing portion can come into contact with the on-off valve membrane to exert an action of preventing such deformation of the on-off valve membrane due to the contact action from the housing portion side. Therefore, it is difficult for feces to enter from the accommodation portion side with respect to the proximal end opening of the cleft cleft. It is difficult for the excreted feces once stored in the storage portion to flow backward to the proximal end opening portion and thus the distal end opening portion side in the buttocks cleft facing portion. Such a configuration, which is suitable for suppressing the backflow of excrement, is suitable for maintaining the accommodation state of the excrement contained in the accommodating portion, and by extension, the wearer or the diaper change worker excretes excrement. Contributes to suppressing stains.

As described above, the disposable diaper according to the second aspect of the present invention is suitable for suppressing the wearer and the diaper changing worker from being soiled by excrement.

In the first and second aspects of the present invention, the gluteal cleft opposing portion preferably has an adhesive portion around the tip opening for attaching around the anus. Such a configuration is suitable for receiving feces excreted from the wearer through the distal end opening of the gluteal cleft facing portion, and is therefore suitable for leading to the accommodating portion.

Preferably, the exterior inner sheet has an assembly opening, and the gluteal cleft facing portion is assembled to the exterior inner sheet via a stretchable elastic material in the assembly opening. The elastic material is, for example, a string-shaped rubber material or an elastic sheet material. According to such a configuration, when the disposable diaper of the present invention is worn, a good contact state or a close contact state of the gluteal cleft opposing part with respect to the gluteal cleft of the wearer is realized by utilizing the biasing force due to the elastic material. Therefore, it is easy to receive excretion from the wearer through the tip opening of the gluteal cleft.

When a stretchable sheet material is used as the stretchable material, the stretchable sheet material and the gluteal cleft facing portion preferably close the assembling opening of the exterior inner sheet. Such a configuration is suitable for keeping feces excreted from the wearer in the accommodation section in a state of being separated from the wearer's body, and therefore, for preventing the wearer and diaper change workers from becoming soiled with excrement. To contribute.

The gluteal cleft facing portion preferably includes a tip apex portion in which a tip opening portion is formed and a pair of inclined surface portions connected to each other via the tip apex portion. The gluteal cleft facing portion having such a configuration easily abuts the gluteal cleft portion that is recessed in the wearer's body, with the tip opening facing the wearer's anus. Therefore, the gluteal cleft facing portion having such a configuration easily receives feces from the wearer at the tip opening portion.

The pair of inclined surface portions in the buttocks cleft facing portion are preferably configured to be capable of opening and closing legs. That is, it is possible to perform both movements of an open leg movement in which the opening angle of the pair of inclined surface portions connected via the tip apex portion in the buttocks cleft facing portion increases, and a closing leg movement in which the opening angle decreases after the leg is opened. In addition, it is preferable that the pair of inclined surface portions be configured. In such a gluteal cleft facing portion, the opening size of the tip opening portion that opens at the tip apex portion increases as the pair of inclined surface portions open, that is, the opening angle of the pair of inclined surface portions increases. There is a tendency. When such a gluteal cleft opposing part is assembled to the exterior inner sheet through an elastic material in the assembly opening of the exterior inner sheet, the feces being excreted from the anus of the gluteal cleft of the wearer are cleaved. When a pressing action is applied to the tip apex portion or the tip opening of the facing portion, the pair of inclined surface portions in the gluteal cleft facing portion, which is assembled to the exterior inner sheet through the elastic member, opens the legs to open the leading end. The opening size of the part becomes large, and therefore, the excretion and stool are easily received in the opening part.

The accommodating portion preferably has an accommodating bag body arranged between the exterior inner sheet and the exterior outer sheet in the main body portion. In such a structure, the feces excreted from the wearer of the present diaper will be stored in the storage bag. This configuration is suitable for retaining feces excreted from the wearer in a state of being separated from the wearer's body, and thus contributes to preventing the diaper wearer and the diaper changing operator from becoming soiled with excrement.

The main body portion of the disposable diaper of the present invention preferably has a multilayer structure further including a top sheet together with the exterior inner sheet and the exterior outer sheet described above. In the multilayer structure, the top sheet is located on the inner side of the diaper, that is, on the wearer side than the both exterior sheets. The diaper preferably further includes an absorption unit having a function of absorbing excrements such as excretion urine between the top sheet and the exterior inner side sheet.

The on-off valve membranes 60 are joined to the region around the mountain-shaped pad 30 in the elastic material 14. A hot melt adhesive, for example, can be used for this joining. Each on-off valve membrane 60 has, for example, a tongue shape. Examples of the constituent material of the opening/closing valve membrane 60 include a resin film such as a flexible plastic film and a flexible paper material.

The on-off valve membrane 60 may be arranged facing the opening 30b (base end opening) side of the mountain pad 30 in the mode shown in FIG. 11 instead of the mode shown in FIG. 11A and 11B are cross-sectional views of the mountain pad 30 included in the diaper X2 and its vicinity, respectively, and FIGS. 7A and 7B for the diaper X1 described above. Corresponds to the sectional view of FIG. In the embodiment shown in FIG. 11 as well, similar to the embodiment shown in FIG. 10, each on-off valve membrane 60 is bonded to the elastic member 14 so that the two on-off valve membranes 60 can cooperate to close the opening 30b. ..

Regarding the configurations of the main body portion 10, the absorption unit 20, the chevron pad 30, and the storage portion 50 in the diaper X2, the main body portion 10, the absorption unit 20, the chevron pad 30, and the storage portion 50 described above regarding the diaper X1 are each. The configuration is the same.

When using the diaper X2 having the above-mentioned configuration, the mountain pad 30 should be in contact with the wearer's gluteal cleft at a position/posture where the opening 30a of the mountain pad 30 faces the wearer's anus. The diaper X2 is worn by the user. Then, the feces excreted from the wearer can be received by the opening 30a of the mountain pad 30 that abuts the buttocks of the wearer, pass through the mountain pad 30, and reach the accommodation portion 50. The excreted feces will be accommodated in the accommodation bag 51.

The configuration in which the diaper X2 includes the excrement container 50 between the exterior inner sheet 12 and the exterior outer sheet 13 of the main body 10 is used to keep feces excreted from the wearer apart from the wearer's body. Therefore, it is suitable for preventing the wearer or his/her body from becoming soiled by excrement. When the diaper changing operation is performed on the diaper X2 while the excrement and feces are stored in the storage portion 50, the body of the worker, such as the hand, is not easily soiled.

In addition, the configuration in which the diaper X2 is provided with the mountain pad 30 that has the opening 30a that is a fecal receiving port and can contact the wearer's cleft, guides feces from the wearer to the accommodating portion 50. In addition, it contributes to suppressing the wearer and the diaper change worker from being soiled by excrement.

In addition, the mountain-shaped pad 30 is arranged so as to face the opening 30b (base end opening) side and is deformed due to the weight of excrement and the like to an open state in which the opening 30b communicates with the accommodating portion 50. The above-described configuration in which the diaper X2 is provided with the possible opening/closing valve membrane 60 is suitable for suppressing the backflow of feces from the accommodating portion 50 toward the opening 30a (tip opening) of the mountain pad 30. The opening/closing valve membrane 60, which is arranged so as to face the opening 30b side of the mountain pad 30 so as to partition between the opening 30b of the mountain pad 30 and the accommodating portion 50, is formed in the mountain pad 30. When excreted feces received via 30a pass through the opening 30b and the on-off valve membrane 60, they are easily deformed to allow the passage. On the other hand, the opening/closing valve membrane 60 is unlikely to be deformed to an open state that allows the opening 30b and the housing portion 50 to communicate with each other due to the contact action from the housing portion 50 side. This is because the wall portion around the opening 30b of the mountain pad 30 can come into contact with the on-off valve membrane 60 and exert an effect of preventing such deformation of the on-off valve membrane 60 due to the contact action from the housing portion 50 side. .. Therefore, it is difficult for feces to enter from the accommodation portion 50 side into the opening 30b of the mountain pad 30. It is difficult for the excreted feces once stored in the accommodating portion 50 to flow backward to the opening 30b of the mountain pad 30 and further to the opening 30a side. Such a configuration that is suitable for suppressing the backflow of excrement is suitable for maintaining the accommodation state of the excretion that is accommodated in the accommodating portion 50, and is eventually excreted by the wearer or the diaper change operator. Contributes to suppressing dirt from stools.

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