Description

Absorbent article

Technical Field

The utility model relates to an absorbent article.

Background

Absorbent articles such as disposable diapers, urine pads, and sanitary products have been developed. Further, for example, the absorbent articles disclosed in japanese patent nos. 6399304 and 6399306 include an absorber covered with a diffusion sheet at a position on the non-skin side of the top sheet.

SUMMERY OF THE UTILITY MODEL

Liquid such as urine excreted from the user passes through the top sheet. The liquid having passed through the top sheet is absorbed by the absorbent body disposed on the non-skin side of the top sheet. Here, when the absorbent body is covered with the liquid-permeable sheet, the liquid penetrates the sheet and reaches the absorbent body. Further, since such a liquid-permeable sheet is made of a material that does not inhibit the permeation of liquid, the liquid tends to permeate the sheet without diffusing in the sheet. Therefore, even when the absorbent body is covered with the liquid-permeable sheet, the liquid easily reaches only a part of the absorbent body. Therefore, it is considered that the absorption efficiency of the absorber is lowered without using the entire absorber.

Accordingly, an object of the present invention is to provide a technique for improving the absorption efficiency of an absorber covered with a liquid-permeable sheet.

In order to solve the above problem, in the present invention, a liquid-permeable sheet covering an absorbent body is overlapped on the skin side.

Specifically, an absorbent article according to one aspect of the present disclosure is an absorbent article that absorbs liquid discharged from a user, the absorbent article including: an absorbent body capable of absorbing the liquid; a liquid-permeable sheet that covers the absorber from a non-skin side and has an overlapping portion that overlaps on a skin side; and a flow path that can flow the liquid, the flow path having the overlapping portion as at least a part of an inner wall.

In the absorbent article according to the above aspect, the adhesive may be an adhesive that can be melted by heat to bond the overlapping portions to each other.

In the absorbent article according to the above aspect, the flow path may have a concave portion that is concave toward the non-skin side at the skin-side portion of the absorbent body, and the liquid-permeable sheet may have a length that can cover the absorbent body along a surface where the concave portion is formed and that can dispose the overlapping portion at the bottom of the concave portion.

In the absorbent article according to the above aspect, the absorbent article may further include a 2 nd absorbent body overlapping the absorbent body on the skin side of the absorbent body covered with the liquid-permeable sheet, and the 2 nd absorbent body may have a groove provided so as to face the concave portion.

In the absorbent article according to the above aspect, the absorbent body may include a granular absorbent material on the skin side.

In the absorbent article according to the above aspect, the overlapping portion may be fixed to a surface of the absorbent body on the skin side, the overlapping portion facing the surface.

In the absorbent article according to the above aspect, the surface of the absorbent body other than the skin side may be fixed to the inner surface of the liquid-permeable sheet facing the absorbent body.

In the absorbent article according to the above aspect, the flow path may have a concave portion that is concave toward the non-skin side at the skin-side portion of the absorbent body, the overlapping portions may be non-bonded to each other, and the liquid-permeable sheet may have a length that allows the overlapping portions to overlap each other even when the absorbent body absorbs the liquid.

Detailed Description

Hereinafter, an absorbent article according to an embodiment of the present invention will be described with reference to the drawings. The configurations of the following embodiments are merely examples, and the present invention is not limited to the configurations of these embodiments.

< embodiment 1 >

In the present embodiment, a direction connecting a front body disposed to face an abdomen of a user and a rear body disposed to face a back of the user is defined as a longitudinal direction in the tape-type disposable diaper. The crotch portion disposed in the crotch of the user (disposed opposite to the crotch) is located between the front body (one side in the longitudinal direction) and the rear body (the other side in the longitudinal direction) (the center in the longitudinal direction). In a state where the diaper is worn by a user (hereinafter, simply referred to as "worn state"), a side facing the skin of the user (an inner side in the worn state) is referred to as a skin surface side, and an opposite side to the skin surface side (an outer side in the worn state) is referred to as a non-skin surface side. The direction connecting the skin surface side and the non-skin surface side is defined as a thickness direction, and the direction perpendicular to both the longitudinal direction and the thickness direction is defined as a width direction. In addition, the case of viewing from the thickness direction is referred to as planar viewing.

Fig. 1 is a perspective view of a diaper of the present embodiment. The diaper 1 has: a crotch region 1B, the crotch region 1B corresponding to a crotch region that covers a user's pudendum when worn; a front body region 1F, the front body region 1F being a part corresponding to the front body of the user and located in front of the crotch region 1B; and a rear body region 1R, the rear body region 1R being a portion corresponding to the rear body of the user and located on the rear side of the crotch region 1B. Tapes 2L and 2R are provided on both left and right edges of the back region 1R so as to be attachable to the front patch 2F provided on the non-user side surface of the front region 1F. Therefore, when the tapes 2L and 2R are attached to the front patch 2F in a state where the front body region 1F is disposed on the abdominal side of the user and the rear body region 1R is disposed on the back side of the user, the diaper 1 is fixed to the body of the user in a state of surrounding the abdominal circumference and the thighs of the user. Since the diaper 1 is fixed to the body of the user in this manner, the user can walk while standing with the diaper 1 worn.

In the diaper 1, an absorbent body capable of absorbing and retaining liquid is arranged mainly in the vicinity of the crotch region 1B. The diaper 1 further includes a diaper pad 10 having an absorbent body inside the absorbent body. The diaper 10 is detachably attached to the main body of the diaper 1 and is disposed from the front body region 1F to the rear body region 1R. By arranging the urine pad 10 in this manner, the user is covered with the urine pad 10 from the urethral orifice to the anus. Therefore, the urine excreted by the user is absorbed by the urine collection pad 10. In addition, since the urine excreted by the user is mainly absorbed by the urine pad 10, the user can adopt a method of use in which the urine pad 10 is replaced several times a day and the main body of the diaper 1 is replaced once a few days.

In the diaper 1, in order to suppress the formation of a gap which becomes an outflow path of the liquid between the diaper 1 and the skin of the user, the three-dimensional gathers 3BL, 3BR are provided at a portion surrounding the thighs of the user, and the waist gather 3R is provided at a portion surrounding the abdominal circumference of the user. The three-dimensional gathers 3BL, 3BR and the waist gather 3R are in close contact with the skin of the user by the elastic force of the linear rubber. Therefore, the liquid discharged from the pudendal region of the user is absorbed by the absorbent body of the diaper 1 (the absorbent body of the main body of the diaper 1 and the diaper pad 10) with little leakage from the diaper 1.

Fig. 2 illustrates an outline of a cross-sectional view of the urine pad 10 perpendicular to the longitudinal direction. As shown in fig. 2, the diaper 10 includes a top sheet 7 on the skin side. The diaper 10 is provided with a backsheet 5 on the non-skin side (diaper 1 side). The top sheet 7 and the back sheet 5 are sheet-like members having a substantially rectangular appearance, for example. The back sheet 5 is a sheet made of a liquid impermeable thermoplastic resin for suppressing leakage of excrement. On the other hand, a part or the whole of the top sheet 7 has liquid permeability. Therefore, in a state where the diaper 1 is attached with the urine pad 10, liquid excreted from the user enters the non-skin surface side via the top sheet 7 that may come into contact with the skin of the user. Further, for example, woven cloth, nonwoven cloth, porous film can be used as the material of the top sheet 7. Further, the top sheet 7 may have hydrophilicity.

As shown in fig. 2, the diaper 10 includes an upper absorbent body 11 (an example of the "2 nd absorbent body" in the present disclosure) and a lower absorbent body 13 (an example of the "absorbent body" in the present disclosure) in a space covered with the top sheet 7 and the back sheet 5. The upper layer absorbent body 11 is disposed on the skin surface side with respect to the lower layer absorbent body 13. The upper layer absorbent body 11 is provided with a slit 12 (an example of the "groove" in the present disclosure) at the center in the width direction. The slit 12 is cut in the thickness direction and extends in the length direction.

In addition, in the lower layer absorbent body 13, a concave portion 15 recessed from the skin side toward the non-skin side is provided at the center in the width direction. The concave portion 15 overlaps the slit 12 of the upper layer absorbent body 11 in the thickness direction. The width of the recess 15 is set to be larger than the width of the slit 12. The width of the recess 15 may be equal to the width of the slit 12, or may be narrower than the width of the slit 12.

The urine pad 10 includes SAP (Super Absorbent Polymer, an example of the "particulate Absorbent material" of the present disclosure) as a particulate Absorbent resin. Such SAP is dispersed on the skin-side surface (not shown) of the lower absorbent body 13. Further, the SAP may be trapped in the lower absorbent body 13 by pressing the surface of the lower absorbent body 13 on the skin side to the non-skin side in a state where the SAP is dispersed in the surface.

The SAP is a hydrophilic polymer having a crosslinked structure capable of absorbing and retaining water in gaps between short fibers of cellulose fibers such as pulp fibers, rayon fibers, and cotton fibers, or short fibers obtained by hydrophilizing synthetic fibers such as polyethylene, polypropylene, and polyethylene terephthalate. Therefore, in the SAP, the volume change of the absorbent resin before and after the absorption of the liquid is basically performed in the short fibers holding the absorbent resin in the gaps.

The SAP particles of the present embodiment are particles obtained by granulating a resin composition containing an SAP. The "SAP-containing resin composition" referred to herein is a concept including both a composition composed of only an SAP and a composition containing an SAP as a main component and containing therein other substances to such an extent that the water absorbability is not adversely affected. Examples of the "other substances" include additives (such as a surface modifier added for the purpose of hydrophobizing the particle surface), unreacted monomers remaining during SAP synthesis, and the like.

The diaper 10 is provided with a core wrap sheet 21 (an example of the "liquid-permeable sheet" of the present disclosure). The core wrap sheet 21 is a liquid-permeable sheet made of, for example, tissue such as paper towel, woven cloth, nonwoven fabric, porous film, or the like. The outer shape of the core wrap sheet 21 is, for example, a rectangular shape having a longer length in the width direction than in the longitudinal direction. The core wrap sheet 21 covers the lower layer absorber 13 from the non-skin surface side. The core wrap sheet 21 is bent near the edge of the opening of the recess 15, and is arranged so as to extend along the side surface of the recess 15. In addition, at the bottom of the recess 15, an overlapping portion 17 (an example of "overlapping portion" in the present disclosure) is disposed in which one end portion of the chip-packaging sheet 21 overlaps the other end portion in the width direction. That is, the length of the core wrap sheet 21 in the width direction is such a length that the bottom of the concave portion 15 overlaps by a predetermined length when the lower layer absorbent body 13 is covered from the non-skin surface side in this manner.

Hot melt adhesives 16 (an example of "adhesive" in the present disclosure) are provided on surfaces of the overlapping portion 17 that face each other. The hot melt adhesive 16 melts at a temperature of, for example, about 60 to 100 degrees. Then, the core wrap sheets 21 forming the overlapping portion 17 are bonded to each other. Fig. 2 illustrates a state in which the hot-melt adhesive 16 is melted and the surfaces facing each other in the overlapping portion 17 are bonded to each other.

[ use example ]

Fig. 3 illustrates a state in which the urine pad 10 is used. When urine is excreted from the urethral orifice of the user when the diaper 10 is worn, the urine flows on the top sheet 7. The top sheet 7 allows part of urine to pass therethrough. Therefore, the urine reaches the upper absorbent body 11 and is absorbed. Further, a part of the urine having passed through the top sheet 7 flows through a flow path (an example of the "flow path" in the present disclosure) formed by the slit 12 and the concave portion 15.

The urine flowing through the concave portion 15 passes through the core wrap sheet 21 and enters the placement portion of the lower absorbent body 13. Then, a part of the urine having passed through the core wrap sheet 21 reaches the lower layer absorbent core 13 and is absorbed therein. Here, the lower absorbent body 13 contains SAP. Therefore, the lower absorbent body 13 expands in volume as a whole.

The core wrap sheet 21 disposed at the bottom of the recess 15 has an overlapping portion 17. Here, since the overlapping portion 17 overlaps the core wrap sheet 21, the permeability of urine decreases. Further, since the hot melt adhesive 16 is provided in the overlapping portion 17, the penetration of urine is also hindered by the hot melt adhesive 16. Therefore, the urine flowing through the recess 15 can be prevented from passing through the overlapping portion 17.

[ Effect, effect ]

According to the urine pad 10 as described above, urine flowing through the concave portion 15 can be prevented from permeating the overlapping portion 17. Therefore, the flow of urine in the longitudinal direction of the recess 15 can be promoted. After the urine has been distributed throughout the entire concave portion 15 in this manner, the urine passes through the core wrap sheet 21 and enters the placement portion of the lower absorbent body 13. Therefore, the efficiency of urine absorption by the lower absorbent body 13 is improved.

Further, according to the diaper 10 as described above, the core wrap sheet 21 is disposed between the upper layer absorbent body 11 and the lower layer absorbent body 13. Therefore, when the SAP contained in the lower layer absorbent body 13 absorbs urine and swells, the SAP can be suppressed from moving and entering the slit 12 of the upper layer absorbent body 11. In addition, such movement of the SAP into the slit 12 is also restricted by the core wrap sheet 21 being bonded by the hot melt adhesive 16 at the overlapping portion 17. Therefore, the SAP can be prevented from moving to the slit 12 and reducing the urine flow-through of the slit 12. Therefore, urine flows throughout the entire slit 12. Therefore, urine is absorbed throughout the entire upper absorbent body 11. Therefore, the efficiency of urine absorption by the upper absorbent body 11 is improved.

In addition, according to the urine pad 10 as described above, the longer the overlapping portion 17 can be disposed at the bottom of the concave portion 15, the more the length of the core wrap sheet 21 in the width direction becomes. Therefore, even when the lower layer absorbent body 13 absorbs urine and swells, the core wrap sheet 21 can be suppressed from being broken. Further, by bonding the surfaces of the overlapping portions 17 facing each other with the hot-melt adhesive 16, the breakage of the core wrap sheet 21 can also be suppressed.

Further, according to the urine pad 10 as described above, the slit 12 and the concave portion 15 are arranged so as to overlap in the thickness direction. Further, an overlapping portion 17 is disposed at the bottom of the recess 15. Therefore, if the permeability of urine decreases at the overlapping portion 17, the flow-through property of urine in the longitudinal direction of the slit 12 communicating with the concave portion 15 is improved. Therefore, urine flows throughout the entire slit 12. Therefore, urine is absorbed throughout the entire upper absorbent body 11. Therefore, the efficiency of urine absorption by the upper layer absorbent body 11 is improved.

[ 1 st modification ]

Fig. 4A and 4B show an outline of a cross-sectional view of a diaper 10A according to modification 1 perpendicular to the longitudinal direction. Fig. 4A shows an example of a state before the lower absorbent body 13A absorbs urine. Fig. 4B shows an example of a state after the lower absorbent body 13A has absorbed urine.

The urine pad 10A of modification 1 has the same configuration as the urine pad 10 of embodiment 1. However, as shown in fig. 4A and 4B, the hot melt adhesive 16 is not provided in the overlapping portion 17A of the urine pad 10A, and the surfaces of the overlapping portion 17A facing each other are not bonded to each other. The length of the core wrap sheet 21A is a length that allows the core wrap sheets 21A to overlap each other at the overlapping portion 17A even when the lower layer absorbent body 13A absorbs urine and swells.

[ action, effect ]

According to the diaper 10A as described above, the hot melt adhesive 16 is not provided, and the surfaces of the overlapping portion 17A facing each other are not bonded to each other. Therefore, the shape of the core wrap sheet 21A is flexibly changed. Therefore, as shown in fig. 4B, it is possible to reduce the occurrence of the swelling of the lower absorbent body 13A being suppressed when the lower absorbent body 13A absorbs urine. Therefore, the lower absorbent body 13A swells in the thickness direction, and the depth of the concave portion 15A increases. As shown in fig. 4B, the core wrap sheet 21A can cover the side surface of the expanded recess portion 15A so as to follow the side surface. Therefore, the flow path cross-sectional area of the concave portion 15A covered with the core wrap sheet 21A is larger than that before absorption of urine shown in fig. 4A. Therefore, the outflow of urine from the recess 15A can be suppressed. In other words, urine is easily distributed throughout the recess 15A. The urine throughout the entire concave portion 15A penetrates the core wrap sheet 21A and enters the placement portion of the lower absorbent body 13A. Therefore, the efficiency of urine absorption by the lower absorbent body 13A is improved.

As shown in fig. 3, in the diaper 10 of the embodiment, similarly to the diaper 10A, the lower absorbent body 13 absorbs urine and swells in the thickness direction, so that the depth of the concave portion 15 increases. However, the surfaces of the overlapping portion 17 that face each other are bonded to each other. Therefore, the circumferential length of the lower layer absorber 13 in the width direction is increased, whereas the length of the core wrap sheet 21 in the width direction is not changed. Therefore, as shown in fig. 3, the core wrap sheet 21 is separated from the side surface of the expanded recess 15, and the overlapping portion 17 is in a state of being lifted from the bottom surface of the recess 15. Therefore, the flow passage cross-sectional area of the recess 15 covered with the core wrapping sheet 21 is smaller than the flow passage cross-sectional area of the recess 15A of the 1 st modification. In addition, the area of the core wrap sheet 21 that is in contact with the concave portions 15 of the lower absorbent body 13 is reduced. Therefore, the efficiency of absorption of urine that has passed through the core wrap sheet 21 disposed in the concave portion 15 by the lower absorbent body 13 from the side surface or the bottom surface of the concave portion 15 is reduced.

On the other hand, according to the urine pad 10A of modification 1, as shown in fig. 4B, the core wrap sheet 21A can cover the side surface of the expanded concave portion 15A so as to follow the side surface. Even when the lower absorbent layer 13 swells, the superposed section 17 can be prevented from floating from the bottom surface of the concave section 15. Therefore, the flow path cross-sectional area of the recess 15A covered with the core wrap sheet 21A is larger than that of the embodiment. In addition, the area of the side surfaces and the bottom surface of the recess 15A of the lower absorbent body 13A in contact with the core wrap sheet 21A becomes large. Therefore, the efficiency of absorption of urine that has passed through the core wrap sheet 21A disposed in the concave portions 15A by the lower absorbent body 13A from the side surfaces or the bottom surfaces of the concave portions 15A is improved.

Further, according to the diaper 10A as described above, even when the lower absorbent layer 13A absorbs urine and swells, the core wrap sheets 21A overlap each other at the overlapping portion 17A. Therefore, it is possible to suppress, for example, the lower layer absorbent body 13A from being exposed without being covered with the core wrap sheet 21A due to swelling of the lower layer absorbent body 13A. That is, variations in the degree of coverage of the core wrap sheet 21A covering the lower absorbent body 13A can be suppressed. Therefore, it is possible to suppress a large amount of urine from being absorbed by a specific portion of the lower absorbent body 13A which is not covered with the core wrap sheet 21A. Such a urine pad 10A can make the whole amount of urine absorbed into the lower layer absorbent body 13A uniform. Therefore, the efficiency of urine absorption by the lower absorbent body 13A is improved.

[ modification 2 ]

Fig. 5 illustrates an outline of a cross-sectional view of a diaper 10E of modification 2 orthogonal to the longitudinal direction. The urine pad 10E of modification example 2 has the same structure as the urine pad 10 of embodiment 1. However, in the diaper 10E, the lower layer absorber 13E is provided with a slit 15E penetrating from the skin side to the non-skin side, instead of the concave portion 15. The overlapping portion 17E is disposed near the opening of the slit 15E on the non-skin side. Further, a hot-melt adhesive 19 is provided on the non-skin side of the overlapping portion 17E. The hot melt adhesive 19 bonds the non-skin side of the overlapping portion 17E to the inner surface of the core wrap sheet 21E located at the bottom of the slit 15E.

The diaper 10E as described above provides the same effects as those of the diaper 10 of embodiment 1. Further, according to the diaper 10E as described above, the inner surface of the core wrap sheet 21E positioned at the bottom of the slit 15E and the overlapping portion 17E are bonded by the hot melt adhesive 19. Therefore, the overlapping portion 17E can be suppressed from being displaced from the central bottom portion of the slit 15E. Therefore, the effect of the urine pad 10 as described in embodiment 1 can be reliably exhibited.

[ modification 3 ]

Fig. 6 illustrates an outline of a cross-sectional view of a diaper 10B of a 3 rd modification orthogonal to the longitudinal direction. The urine pad 10B of modification 3 has the same configuration as the urine pad 10 of embodiment 1. However, the urine pad 10B is not provided with the SAP. Therefore, as shown in fig. 6, in the diaper 10B, the lower layer absorbent body 13B and the upper layer absorbent body 11B containing no SAP are overlapped in the thickness direction. The lower layer absorbent body 13B is not provided with the concave portions 15, and has a rectangular cross-sectional shape.

Further, the lower openings of the slits 12B of the upper layer absorbent body 11B are closed by the overlapping portions 17B of the core wrap sheet 21B. That is, the slit 12B and the overlapping portion 17B form a flow path (an example of the "flow path" in the present disclosure) through which urine can flow.

[ action, effect ]

According to the urine pad 10B as described above, the urine flowing through the slit 12B can be prevented from passing through the overlapping portion 17B. Therefore, the flow of urine in the longitudinal direction of the slit 12B can be promoted. The urine thus distributed throughout the entire slit 12B permeates the core-covering sheet 21 and enters the placement portion of the lower absorbent body 13B. Therefore, the lower absorbent body 13B has improved urine absorption efficiency. Further, the urine flowing through the entire slit 12B is also absorbed by the upper layer absorbent body 11B. Therefore, the efficiency of urine absorption by the upper layer absorbent body 11B is improved.

[ 4 th modification ]

Fig. 7 illustrates an outline of a cross-sectional view of a diaper 10D of the 4 th modification orthogonal to the longitudinal direction. The urine pad 10D of modification 4 has the same configuration as the urine pad 10 of embodiment 1.

Further, in the diaper 10D, a hot melt adhesive 20 is provided on the central upper surface of the lower layer absorbent body 13D in fig. 7. The hot melt adhesive 20 bonds the overlapped portion 17D to the central upper surface of the lower absorbent body 13D. Fig. 7 illustrates a state in which the hot-melt adhesive 20 is melted to bond the central upper surface of the lower absorbent body 13D to the overlapping portion 17D.

Further, a hot melt adhesive 18 is provided on the central lower surface of the lower layer absorbent body 13D shown in fig. 7. The hot-melt adhesive 18 bonds the inner surface of the core wrap sheet 21D to the lower surface of the lower absorbent body 13D. Fig. 7 illustrates a state in which the lower surface of the lower layer absorbent body 13D and the inner surface of the core wrap sheet 21D are bonded to each other by melting the hot-melt adhesive 18.

[ action, effect ]

According to the diaper 10D as described above, the central upper surface of the lower absorbent body 13D and the superposed portion 17D are bonded together by the hot-melt adhesive 20, in addition to the diaper 10 of embodiment 1. Therefore, the urine flowing through the recess portion 15D can be further suppressed from passing through the overlapping portion 17D. Therefore, the flow of urine in the flow path formed by the concave portion 15D and the slit 12D is improved.

In the diaper 10D as described above, the lower surface of the lower absorbent body 13D and the inner surface of the core wrap sheet 21D are bonded to each other with the hot-melt adhesive 18. Therefore, even when the lower layer absorbent body 13D swells by absorbing urine, the positional variation of the lower layer absorbent body 13D with respect to the core wrap sheet 21D can be suppressed. Therefore, the overlapping portion 17D can be suppressed from being displaced from the central bottom portion of the recess portion 15D. Therefore, the effect of the urine pad 10 as described in embodiment 1 can be reliably exhibited.

< other modification >

The upper absorbent body 11 may not have the slits 12. In such a case, the concave portions 15 provided in the lower absorbent body 13 exemplify "flow paths" in the present disclosure. The overlapping portions 17 bonded with the hot melt adhesive 16 may be disposed on the side portions in the thickness direction of the concave portions 15 and/or the portions of the lower absorbent body 13 facing the upper absorbent body 11. In the above-described embodiment and modification, urine is exemplified as an example of the liquid excreted from the user, but the liquid may be a substance that can flow through the flow path, such as watery feces.

The embodiments and the modifications disclosed above can be combined separately.
