1 to 4 show an example of a body fluid treatment product according to the present invention. FIG. 1 is a plan view of the body fluid treatment product 1, FIG. 2 is a schematic diagram of a section taken along line II-II in FIG. FIG. 4 is a partial perspective view of the bodily fluid treatment article 1, and FIG. In FIG. 1 and 3, the part is fractured | ruptured for description. As illustrated, the body fluid treatment article 1 has a longitudinal direction Y and a lateral direction X, and is formed at a position corresponding to the opening 11 and a liquid-impermeable container 10 having a plurality of openings 11. And backflow prevention means 20.

The container 10 includes a first sheet 12 located on the body side, and a second sheet 13 located on the clothing side opposite to the body side, and the first and

second sheets

12 and 13 are around the first sheet 12. Are joined together to form a bag. An opening 11 that penetrates in the thickness direction is formed in the first sheet 12, and urine, which is a body fluid, flows through the opening 11. The adjacent openings 11 are arranged so as not to overlap each other in the vertical direction Y and the horizontal direction X. As the first and

second sheets

12 and 13, a liquid-impermeable sheet, for example, a laminate of a plastic film and a fiber nonwoven fabric, or a fiber nonwoven fabric such as a melt blown fiber nonwoven fabric having a relatively high density of ultrafine fibers may be used. it can.

The backflow preventing means 20 corresponds to the opening 11 and is located on the inside of the housing 10 of the first sheet 12 and has a flat valve body 30 having a specific gravity smaller than that of body fluid such as urine, and the valve body 30 includes the housing 10. It includes a sheet-like support body 40 for preventing the inside from falling off, and a spacer 50 interposed between the first sheet 12 and the support body 40.

As the valve body 30, for example, a liquid-impervious sheet made of a fiber panel, foamed plastic, or paper-like material having higher rigidity and water resistance than the container 10 or the support body 40 can be used. It has the valve body upper surface 31 located in the 12th side, and the valve body lower surface 32 located in the 2nd sheet | seat 13 side. A plurality of valve bodies 30 are formed corresponding to the plurality of openings 11, and the area of the valve body 30 is larger than the opening area of the opening 11, and the peripheral portion of the valve body upper surface 31 is the container 10 of the opening 11. It is possible to make watertight contact with the inner periphery 14 of the opening. In this embodiment, the diameter of the opening 11 is about 6 mm, and the diameter of the valve body 30 is about 12.5 mm. However, it is not limited to this dimension, and can be appropriately changed according to the number and position of the openings 11, the size of the body fluid treatment article 1, and the like.

A spacer 50 is disposed between the first sheet 12 and the support 40. As the spacer 50, for example, a relatively high shape-retaining property such as a fiber panel, foamed plastic, or paper material can be used. The spacer 50 has an approximately oval shape, has an area covering all of the plurality of openings 11, and has the major axis direction aligned with the longitudinal direction Y and the minor axis direction aligned with the lateral direction X. The spacer 50 includes a spacer upper surface 51 positioned on the first sheet 12 side and a spacer lower surface 52 positioned on the second sheet 13 side. The spacer upper surface 51 is in contact with the first sheet 12 and is supported by the spacer lower surface 52. They are brought into contact with the body 40 and joined by joining means such as an adhesive. A spacer opening 53 penetrating from the spacer upper surface 51 to the spacer lower surface 52 is formed in the spacer 50 so as to correspond to the opening 11, and the valve body 30 is disposed in the spacer opening 53. As the support body 40, for example, a liquid-permeable fiber nonwoven fabric can be used.

A space 15 is formed between the first sheet 12 and the support 40 by the spacer opening 53. The valve body 30 is supported so as to be movable in the thickness direction of the spacer 50 in the space 15. That is, the diameter of the spacer opening 53 is larger than the diameter of the opening 11 and further larger than the diameter of the valve body 30. The thickness dimension of the spacer 50 is made larger than that of the valve body 30. Specifically, the thickness of the valve body 30 is about 0.5 mm, and the thickness dimension of the spacer 50 is about 2 mm.
Since the support body 40 is joined to the spacer lower surface 52, the valve body 30 does not fall into the housing body 10. Further, the movement of the valve body 30 in the vertical direction Y and the horizontal direction X is restricted by the peripheral wall of the spacer 50, the opening peripheral edge 14, and the support body 40.

When body fluid such as urine is excreted in the opening 11 of the body fluid treatment article 1, the valve body 30 is pushed down toward the support body 40 by the weight of the body fluid, and the valve body lower surface 32 is attached to the support body 40. Touched and supported. The peripheral edge 14 of the opening and the valve body upper surface 31 are separated from each other, and the body fluid flows into the space 15 through the periphery of the valve body 30. Furthermore, the body fluid passes through the support body 40 and flows into the container 10. Since the container 10 is impermeable and has a bag shape, the body fluid is held in the container 10.

As shown in FIG. 4, when the body fluid is held upside down from the state in which the body fluid is held in the housing body 10, the body fluid moves toward the opening 11 and the valve of the valve body 30. The body lower surface 32 is pressed by the body fluid that has passed through the support body 40 and moves to the first sheet 12 side. In the valve body 30, the valve body upper surface 31 is in contact with the opening peripheral edge 14. Since the valve body 30 is pressed by the body fluid, the valve body 30 can be contacted with the periphery of the opening 14 in a watertight manner, and the body fluid can be prevented from flowing out of the housing body 10.
Further, since the specific gravity of the valve body 30 is smaller than that of the body fluid, the valve body 30 can float on the body fluid. When the body 10 is in the state shown in FIG. 2 and body fluid such as urine is held in the body 10, the valve body 30 floats on the body fluid, so that before the body fluid flows out from the opening 11, the opening 11 is closed by the valve body 30. Therefore, even in this case, the body fluid can be prevented from flowing out of the container 10.

When a slight amount of body fluid remains between the valve body 30 and the first sheet 12, the valve body upper surface 31 and the opening peripheral edge 14 of the first sheet 12 are more separated by the surface tension of the body fluid. It is possible to improve the effect of preventing the body fluid inside the container 10 from flowing out.
Since a plurality of openings 11 and backflow prevention means 20 are formed, even if any of the valve bodies 30 cannot move in the thickness direction for some reason, the entire function of the region of backflow prevention means 20 Failure can be avoided. Moreover, it becomes possible to form the some opening part 11 and the backflow prevention means 20 in the wide range as needed, and a bodily fluid can be reliably accommodated in the accommodating body 10 inside.

5 to 7 show an example of a wearing article including the body fluid treatment article 1 as described above. The disposable diaper 2 is demonstrated as an example as a wearing article.
5 is a perspective view of the diaper 2, FIG. 6 is a plan view of the diaper 2 when the joining of both side edges in FIG. 5 is released, and FIG. 7 is a sectional view taken along line VII-VII in FIG. is there. 5 and 6 show a state in which a part thereof is broken for explanation, each elastic member is extended against the contraction force, and the diaper 2 is kept flat. The diaper 2 includes a chassis 60 and a liquid absorption structure 70. The chassis 60 includes a front waist region 61, a rear waist region 62, and a crotch region 63 positioned between the front and

rear waist regions

61, 62, and a vertical virtual center that bisects the dimension in the lateral direction X. It has a line PP and a horizontal virtual center line QQ that bisects the dimension in the vertical direction Y.

The chassis 60 includes a liner 64 that forms the body side and an outer 65 that forms the clothing side opposite to the liner 64. The chassis side edges 66 extend in the vertical direction Y, and the chassis front and rear end edges 67 extend in the horizontal direction X. , 68. The chassis side edges 66 are curved toward the longitudinal virtual center line PP in the crotch region 63. The liner 64 and the outer 65 may be made of a conventional material in the art such as a liquid-permeable fiber nonwoven fabric.
A leg elastic body 82 is attached to the crotch region 63 so as to be retractable along the chassis side edges 66 in an extended state. The leg elastic body 82 is joined between at least one of the liner 64 and the outer 65.

A relatively wide waist elastic body 81 is attached along the front and

rear edges

67 and 68 of the chassis so as to be contractible in an extended state in the lateral direction X. The waist elastic body 81 is further joined to the body side of the liner 64. As the waist elastic body 81 and the leg elastic body 82, a stretchable fiber nonwoven fabric can be used. However, it is not limited to a stretchable fiber nonwoven fabric, and a known elastic body of this type of article can be used. As shown in FIG. 5, the chassis side edges 66 are joined to each other in the front and

rear waist regions

61 and 62 to form a pant-type diaper 2.

The chassis 60 has a chassis opening 69 that penetrates the liner 64 and the outer 65 in the thickness direction at least in the crotch region 63. In this embodiment, the chassis opening 69 is formed in a substantially elliptical shape extending from the crotch region 63 to the front and

rear waist regions

61 and 62. A top sheet 17 is disposed between the liner 64 and the outer 65 so as to close the chassis opening 69. In the top sheet 17, a substantially elliptical top opening 18 is formed closer to the chassis front end edge 67 than the horizontal virtual center line QQ. The top opening 18 penetrates the top sheet 17 in the thickness direction and has an area smaller than the opening area of the chassis opening 69.

A liquid absorption structure 70 is formed on the clothing side of the outer 65 so as to close the chassis opening 69, that is, to overlap the top sheet 17. The liquid absorbing structure 70 includes a body side and a clothing side which is the opposite side, a liquid absorbing core material 71, and a covering sheet 72 covering the liquid absorbing core material 71. The horizontal virtual center line QQ A liquid absorption opening 74 is formed on the chassis front end edge 67 side so as to overlap the top opening 18. The liquid absorption opening 74 penetrates the liquid absorption core material 71 in the thickness direction. Conventional materials in this technical field such as a mixture of fluff pulp and superabsorbent polymer particles can be used for the liquid-absorbent core material 71, and liquid diffusible tissue paper can be used for the covering sheet 72.
The body fluid treatment article 1 is attached to the clothing side of the liquid absorbing structure 70, and the cover sheet 73 is attached to the clothing side. As the cover sheet 73, a liquid-impermeable film or the like can be used. Moreover, the fiber nonwoven fabric can be arrange | positioned further on the clothing side of the cover sheet 73, and the touch can also be improved.

In the bodily fluid treatment article 1 disposed between the liquid absorbing structure 70 and the cover sheet 73, the first sheet 12 is positioned on the liquid absorbing structure 70 side, and the second sheet 13 is positioned on the cover sheet 73 side. Has been. The opening 11 of the body fluid treatment article 1 is located on the chassis front end edge 67 side with respect to the horizontal virtual center line QQ, and is exposed to the body side through the liquid absorption opening 74 and the top opening 18 of the liquid absorption structure 70. Has been. The opening 11 is positioned to correspond to the wearer's external genitalia.

In the diaper 2 as described above, when the wearer urinates, the urine is accommodated in the container 10 of the body fluid treatment article 1 through the opening 11. When the bodily fluid treatment article 1 is in the state of FIG. 2, urine passes through the periphery of the valve body 30 and is accommodated in the container 10, and the wearer lies down or becomes all fours, resulting in the state of FIG. When this happens, the valve body 30 and the peripheral edge 14 of the opening of the first sheet 12 are in watertight contact, and the urine stored in the container 10 can be prevented from flowing back to the wearer. Further, when the wearer sits down and body pressure acts on the body fluid treatment product 1, the water level of the urine stored in the container 10 rises in the container 10, but the valve body 30 is urine or the like. Since the specific gravity is smaller than that of the body fluid, it can float on the urine, and as a result, the valve body upper surface 21 of the valve body 30 is placed on the peripheral edge 14 of the opening of the first seat 12 before the urine flows out of the container 10. Contact. Accordingly, in this case as well, it is possible to prevent urine from flowing back to the body side. Since urine backflow from the body fluid treatment article 1 can be prevented, urine leakage from the diaper 2 can be suppressed.

Even if urine is removed from the opening 11 of the bodily fluid treatment article 1 and excreted or leaks from the container 10, the liquid absorbing structure 70 exists around the opening 11, and thus the leaked urine is removed. It can be absorbed by the liquid absorbing structure 70. Therefore, urine leakage from the diaper 1 can be further suppressed. Further, the space 15 for holding the valve body 30 is formed by the spacer 50, but by making the valve body into a sheet piece, the dimension in the thickness direction of the spacer 50 can be reduced, and the wearer feels uncomfortable. Can be reduced.

In this embodiment, a liquid absorption opening 74 is formed in the liquid absorption structure 70 of the diaper 2 and the opening 11 of the body fluid treatment product 1 is exposed to the liquid suction opening 74, but the whole body fluid treatment product 1 is sucked. It may be positioned on the body side of the liquid structure 70. In this case, the body fluid treatment article 1 can be formed between the chassis 60 and the liquid absorption structure 70.
Although the chassis opening 69 is formed in the chassis 60, the chassis opening 69 is not necessarily formed. In this case, body fluid such as urine can be permeated into the body fluid treatment article 1 located on the clothing side of the chassis 60 by making at least the portion where the opening 11 of the body fluid treatment article 1 is liquid permeable. . Further, the body fluid treatment article 1 may be formed on the body side of the chassis 60. In any case, it is sufficient that body fluid such as urine is accommodated in the container 10 through the opening 11 of the body fluid treatment article 1. Although the liquid-impervious thing is used as the container 10, it is not necessarily limited to a liquid-impervious thing. As long as the body fluid that has flowed in through the opening 11 can be accommodated, it may be liquid-permeable, and includes, for example, the case where the body fluid is held by a liquid-absorbent core material. However, when a liquid-permeable sheet is used as the first sheet 12, at least the opening periphery 14 is impermeable to allow water-tight contact between the opening periphery 14 and the valve body 30. It is necessary to be. For example, when a liquid-permeable fiber nonwoven fabric is used as the first sheet 12, it can be realized by applying a liquid-impervious film to the peripheral edge 14 of the opening, and a hydrophilic treatment is applied to the hydrophobic fiber nonwoven fabric. When using this as the first sheet 12, it can be realized by not performing the hydrophilic treatment only on the peripheral edge 14 of the opening.

FIGS. 8 and 9 show Embodiment 2 of the present invention, and FIG. 8 is a partial plan view of the body fluid treatment article 1, and a part thereof is broken for explanation. 9 is a cross-sectional view taken along line IX-IX in FIG. In the second embodiment, the body fluid treatment article 1 is characterized in that it does not directly form the opening 11 in the first sheet 12 but separately includes a shape retaining member 90 in which the opening 11 is formed. Other components other than this feature are the same as those in the first embodiment, and detailed description of the same components is omitted.

In the first sheet 12 forming the accommodating portion 10, an attachment opening 16 for attaching the shape retaining member 90 is formed. On the second sheet 13 side of the mounting opening 16, a shape retaining member 90 in which the opening 11 is formed is bonded via a bonding means such as an adhesive. The shape-retaining member 90 can be formed using a material having a relatively high shape-retaining property, such as a fiber panel, foamed plastic, or paper material, and has higher rigidity than the first sheet 12. The shape-retaining member 90 includes a shape-retaining upper surface 91 located on the first sheet 12 side and a shape-retaining lower surface 92 located on the second sheet 13 side, and the shape-retaining upper surface 91 corresponds to the mounting opening 16 of the first sheet 12. The shape retaining lower surface 92 is bonded to the peripheral edge, and the spacer upper surface 51 of the spacer 50 is bonded.

By forming the opening 11 in the shape retaining member 90 and forming the opening 11 in the first sheet 12, the shape of the opening 11 can be maintained as compared with the case where the opening 11 is directly formed in the first sheet 12. Can do. When the opening 11 is distorted and its shape is collapsed, the valve body 30 is difficult to adhere to the opening periphery 14 and a gap may be formed between them. If there is a gap, body fluid such as urine may leak from the gap, but by maintaining the shape of the opening 11, the valve body 30 can more reliably come into water-tight contact and prevent body fluid from leaking. it can. In this embodiment, the peripheral edge 14 of the opening is formed by the shape retaining lower surface 91 of the shape retaining member 90.

Since the opening 11 may be formed in the shape-retaining member 90 and bonded to the first sheet 12, the formation becomes easier as compared with the case where the opening 11 is directly formed in the first sheet 12. That is, the shape-retaining member 90 has an area smaller than that of the first sheet 12 and has high rigidity. Therefore, the shape-retaining member 90 can be easily handled and the opening 11 can be easily formed. Moreover, although the shape-retaining member 90 and the spacer 50 are separate members, they may be formed of the same member.
The shape retaining member 90 is attached to the second sheet 13 side of the first sheet 12, that is, the inside of the housing 10, but may be attached to the outside of the housing 10 that is the opposite side. Such a body fluid treatment article 1 can be used for a wearing article such as a diaper 2 as in the first embodiment.

10 and 11 show Embodiment 3 of the present invention. FIG. 10 is a partially cutaway plan view of the body fluid treatment article 1, and FIG. 11 is a XI-XI line in FIG. It is sectional drawing. The third embodiment is characterized in that one opening 11 is formed in the first sheet 12, and the other components are the same as in the first embodiment. Detailed description of similar components will be omitted.
One opening 11 is formed in the first sheet 12. A valve body 30 is formed between the first sheet 12 and the second sheet 13 so as to be able to contact and separate from the opening periphery 14.

Since the opening 11 is provided in one place, the formation thereof is facilitated, and the number of parts 30 can be reduced because only one valve body 30 is attached to the opening 11. In the third embodiment, the opening portion 11 may be formed in the shape retaining member as in the second embodiment, and the shape retaining member may be attached to the first sheet 12. Moreover, such a bodily fluid treatment article 1 can be used for a diaper 2 as in the first embodiment.
