Description

  The present invention relates to a watery stool leakage prevention sheet that can be used by being attached to the surface side of a top sheet of a disposable diaper, and an absorbent article in which such a watery stool leakage prevention sheet is attached to the surface side of the top sheet. Is.

  In recent years, as a diaper for infants or elderly people / handicapped persons, an absorbent body, a top sheet that is arranged so as to cover the upper surface of the absorbent body, and at least partially made of a liquid-permeable material, and a lower surface of the absorbent body Disposable diapers that are arranged so as to cover the back and are provided with a back sheet made of a liquid-impermeable material are widely used. By using the disposable diaper so that the surface of the top sheet is in contact with the skin of the wearer, the urine excreted by the wearer permeates the top sheet and is absorbed and held by the absorber. In addition, the back sheet excellent in leakage prevention prevents the excrement from leaking to the outside of the diaper.

  However, in the disposable diaper having the above-described configuration, although urine passes through the top sheet, most of the stool does not pass through the top sheet and remains on the top sheet. Since the stool remaining on the top sheet adheres to the wearer's crotch and buttocks, it requires cumbersome wiping work, which increases the burden of childcare and care, and also causes skin troubles for the wearer. It was.

  Then, the disposable sanitary absorbent article and the disposable diaper which formed the recessed part which can collect | store feces in a part of absorber are proposed (for example, refer patent document 1 or 2). Moreover, the disposable diaper with which the stool accommodation bag extended below is attached to the non-contact side of a wearer's skin is proposed (for example, refer patent document 3). These disposable diapers and the like are configured such that the stool excreted by the wearer is accommodated in the recess or the stool accommodation bag.

  In addition, a disposable diaper in which another sheet body (hereinafter referred to as “skin contact sheet”) is disposed on the top of the top sheet has also been proposed (for example, Patent Document 4 or 5). reference). In these disposable diapers, an opening (stool passing opening) through which stool can pass is formed in the skin contact sheet, and the feces excreted by the wearer through the stool passing opening are on the top sheet. Configured to fall into.

Japanese Utility Model Application No. 4-45624 Japanese Patent No. 3012472 JP 2002-253609 A Utility Model Registration No. 2559050 JP 2002-11044 A

  In the disposable diapers described in these documents, the excreted stool is stored in the space below the recess, the storage bag, or the skin contact sheet, thereby reducing the chance that the stool directly contacts the wearer's skin. The effect can be expected.

  However, the disposable diapers described in these documents are designed with the intention of capturing so-called solid stool, and cannot be said to have a structure suitable for capturing soft or watery stool. It was. Therefore, soft stools and watery stools cannot be captured well, and when the wearer is lying down, there is a risk of leakage of soft stools or watery stools from the end of the diaper (especially the back side). There was a problem. In addition, the structure of the disposable diaper becomes complicated by forming a recess in the absorbent body or attaching a storage bag or a skin contact sheet to the disposable diaper, which makes it difficult to manufacture or increases the manufacturing cost. There were also challenges.

  Thus, at present, there is still disclosed a measure that can effectively prevent the leakage of soft stool and watery stool from the end of the diaper (especially the back side) and can be easily manufactured with a simple structure.

  The watery stool leakage prevention sheet of the present invention can effectively prevent leakage of soft stool and watery stool from the end of the diaper (particularly the back side) and can be easily manufactured with a simple structure.

  Hereinafter, the best mode for carrying out the water-like stool leakage preventing sheet and the absorbent article using the same of the present invention will be specifically described with reference to the drawings. However, the present invention broadly encompasses a watery stool leakage prevention sheet having the invention-specific matters and an absorbent article using the same, and is not limited to the following embodiments.

[1] Configuration of the watery feces leakage prevention sheet of the present invention:
The watery stool leakage prevention sheet of the present invention is an auxiliary member of an absorbent article that is used by being attached to the surface side of the top sheet of an absorbent article such as a disposable diaper, and has a sheet material and an outer edge of the sheet material. And a frame material attached so as to surround it, and at least a part of the sheet material is constituted by a liquid-permeable sheet.

  In such a water-like stool leakage prevention sheet, at least a part of the sheet material is composed of a liquid-permeable sheet having excellent liquid permeability, and is attached to surround the outer edge of the sheet material. Depending on the thickness, a space defined by the sheet material and the frame material is formed below the sheet material. For example, the water-like stool leakage prevention sheet 100 shown in FIG. 1 is configured so that the entire sheet material 52 is composed of the liquid-permeable sheet 56 and surrounds the rectangular sheet material 52 and the outer edge of the sheet material 52. A rectangular frame-like frame material 54 is provided, and a rectangular flat plate-like space 58 defined by the sheet material 52 and the frame material 54 is provided below the sheet material 52 according to the thickness of the frame material 54. Is formed.

  Normally, when a disposable diaper is worn, the wearer's skin is in direct contact with the surface of the top sheet of the diaper, and excreted loose stool or watery stool (hereinafter abbreviated as “watery stool”) is absorbed. It can be said that most of the surface of the power top sheet is in a closed state. Therefore, when the watery stool is excreted, the watery stool rapidly spreads in the front-rear direction of the diaper through the extremely narrow space defined by the wearer's groin and the top sheet of the diaper. Leakage will occur from the end (particularly the back end).

  On the other hand, when the watery stool leakage prevention sheet of the present invention is attached to the surface side of the top sheet of the diaper, it is constant between the sheet material (and eventually the wearer's skin) and the top sheet of the diaper depending on the thickness of the frame material. Thus, the wearer's skin and the surface of the top sheet are in a non-contact state. And it can be said that the said space is a very wide space compared with the space divided by a wearer's groin and the top sheet | seat of a diaper. Therefore, when watery stool is excreted on the surface of the sheet material, the watery stool passes through the liquid-permeable sheet and quickly moves to the space, and gradually diffuses in this relatively wide space. become. Moreover, since the surface of the top sheet of a diaper is not obstruct | occluded by a wearer's skin, water-like feces can be absorbed in the whole surface.

  The watery stool leakage prevention sheet of the present invention can effectively prevent leakage from an end portion (particularly the back end portion) of a diaper or the like of a watery stool by the mechanism as described above. Since this effect is obtained only by attaching the water-like feces leakage prevention sheet of the present invention to an absorbent article such as a disposable diaper, the structure of the disposable diaper or the like is not complicated. Further, the watery stool leakage preventing sheet has a relatively simple structure including a sheet material and a frame material, and can be easily manufactured at low cost. Furthermore, when the physical condition is good and the possibility of excretion of watery stool is low, a normal disposable diaper or the like is used, and the water of the present invention is used only when watery stool is likely to be excreted due to diarrhea or the like. Since a stool leakage prevention sheet may be attached to a disposable diaper or the like, it is very economical as compared with a method in which members for measures against watery stool are attached to all disposable diapers in advance. Therefore, it is possible to take measures against leakage of watery stool extremely simply and inexpensively. Moreover, since urine also permeate | transmits a liquid-permeable sheet | seat rapidly and transfers to a top sheet, even if not only watery stool and soft stool but urine is excreted, the problem will not arise in the absorptivity.

[1-1] Sheet material:
The watery stool leakage preventing sheet of the present invention includes a sheet material as a constituent member thereof. This sheet material is a sheet-like member that directly contacts the wearer's skin instead of a top sheet such as a disposable diaper. And at least one part of the sheet | seat material is comprised with the liquid-permeable sheet. With such a configuration, watery feces can be quickly transferred onto a top sheet such as a disposable diaper without staying on the surface of the sheet material.

  In the watery stool leakage preventing sheet of the present invention, “at least a part” of the sheet material may be constituted by a liquid permeable sheet, and the entire sheet material is not necessarily constituted by the liquid permeable sheet. . For example, the watery stool leakage prevention sheet 110 shown in FIG. 2 is an example in which only a part of the sheet material 52 is configured by the liquid permeable sheet 56.

  The configuration of the liquid permeable sheet is not particularly limited, but a sheet having liquid permeability capable of transmitting a suspension such as watery stool or soft stool is preferable. For example, a non-woven fabric sheet having a coarse mesh can pass a liquid using voids between fibers constituting the non-woven fabric. Such a nonwoven fabric may be appropriately selected and used as a liquid-permeable sheet. Among these, an air-through nonwoven fabric can be suitably used because it is bulky and easily subjected to treatment with many voids.

  Further, the liquid permeable sheet can be constituted by a punching sheet in which openings are formed. Such a punching sheet is preferable because it can allow liquid to pass through the openings and has excellent liquid permeability that allows permeation of a suspension such as watery stool or soft stool.

  For example, the watery stool leakage prevention sheet 120 shown in FIG. 3 is an example in which the sheet material 52 is a punching sheet in which an opening 66 is formed, and the entire sheet material 52 is configured as a liquid-permeable sheet 56. is there.

  In this way, the method of forming a hole in the sheet material to make a liquid-permeable sheet is a nonwoven fabric having a basis weight, etc., as compared with the method for securing the liquid passing speed by reducing the basis weight of the nonwoven fabric as described above. Regardless of the nature and characteristics inherently possessed, the predetermined liquid flow rate can be ensured. Moreover, it is preferable at the point which can control a liquid flow rate to a desired value with the area and number of the holes.

  The sheet material forming the openings is preferably a liquid-impermeable sheet or a water-repellent sheet. By adopting such a configuration, the watery stool that has once passed through the liquid-permeable sheet and entered the space between the top sheet such as a diaper and the liquid-permeable sheet penetrates the liquid-permeable sheet and returns. The situation can be effectively prevented. Among them, it is preferable to use a water-repellent sheet that can maintain a light touch (dryness) even when worn for a long time, as well as being able to reduce liquid permeability, and has excellent breathability. It is more preferable to use a water-repellent nonwoven sheet having a good touch.

  Examples of the liquid-impermeable sheet include a liquid-impermeable film made of a resin such as polyethylene used as a constituent material for a disposable diaper back sheet.

  As the water-repellent sheet, a nonwoven fabric such as a spunbond nonwoven fabric or a card embossed nonwoven fabric may be used. It is preferable to use a nonwoven fabric such as a melt blown / spun bond nonwoven fabric.

  As the liquid-permeable sheet, in addition to a low-weight nonwoven fabric sheet or punching sheet, a mesh sheet in which the sheet itself is configured in a mesh shape can be used. The mesh sheet is preferable because it can allow liquid to pass through the mesh-like voids and is excellent in liquid permeability capable of permeating a suspension such as watery stool or soft stool.

  Further, in the watery stool leakage preventing sheet of the present invention, it is also one of preferred modes to use a sheet material that can inhibit the diffusion of watery stool or soft stool for at least a part of the sheet material. By using such a sheet material, rapid diffusion of watery stool can be inhibited or delayed, and leakage of watery stool and soft stool can be effectively prevented.

  As a sheet material that can inhibit the diffusion of watery stool and soft stool, for example, a bulky nonwoven fabric sheet having a large basis weight can be used. A nonwoven fabric sheet having a large basis weight and a high bulk has an effect of absorbing and trapping watery stool and soft stool, and is excellent in diffusion inhibition. Therefore, it is suitably used as a sheet material in the watery stool leakage preventing sheet of the present invention. be able to.

  The nonwoven fabric sheet having a large basis weight and high bulk may be used by appropriately selecting such a nonwoven fabric from conventionally known nonwoven fabrics such as an air-through nonwoven fabric, a card embossed nonwoven fabric and a spunbond nonwoven fabric. Among these, an air-through nonwoven fabric can be suitably used because it is bulky and easily subjected to treatment with many voids.

  In the watery stool leakage prevention sheet of the present invention, it is also preferable that at least a part of the sheet material is constituted by a undulation sheet having a plurality of undulations formed on the surface thereof. If undulations are formed on the sheet surface, it is difficult for watery stools and soft stools to flow, and the diffusion thereof can be inhibited.

  There is no particular limitation on the form of the undulations as long as some undulations are formed on the sheet surface and the diffusion of watery stools and soft stools can be inhibited or delayed. For example, a plurality of undulations may be formed in a dotted manner on the surface of the sheet, or a plurality of undulations may be formed in a continuous or intermittent linear shape on the surface of the sheet. Moreover, the raised sheet | seat which raised the sheet | seat surface also has the effect which inhibits the spreading | diffusion of a liquid by the fuzz.

  For example, the watery stool leakage prevention sheet 130 shown in FIG. 4 is an example in which the sheet material 52 is constituted by an undulating sheet 84 having a plurality of convex portions 82 formed on the surface thereof. In this example, the sheet material 52 is constituted by the liquid permeable sheet 56, and the undulating sheet 84 in which the columnar convex portions 82 are regularly arranged in the vertical direction and the horizontal direction on the surface of the sheet material 52 is used. It is. Such an undulating sheet 84 is characterized by being able to inhibit liquid diffusibility regardless of the arrangement direction.

  5 is an example in which the sheet material 52 is constituted by an undulating sheet 88 having a plurality of recesses 86 formed on the surface thereof. In this example, the sheet material 52 is constituted by the liquid-permeable sheet 56, and the concave portions 86 (dents) in which columnar spaces are formed on the surface of the sheet material 52 are regularly arranged in the vertical direction and the horizontal direction. This is an example using an undulating sheet 88. Such an undulating sheet 88 can also inhibit liquid diffusibility regardless of the arrangement direction.

  The watery stool leakage prevention sheet 130 shown in FIG. 4 and the watery stool leakage prevention sheet 140 shown in FIG. 5 formed undulations by forming only one of the convex portions 82 or 86 on the undulation sheets 84 and 88. Although it is an example, what formed both the convex part and the recessed part is also contained in the scope of the present invention. These sheets can be formed by a method of forming a convex portion by sticking a convex member made of a nonwoven fabric to a nonwoven fabric sheet, or forming a concave portion by embossing the nonwoven fabric sheet. There is no restriction | limiting in particular about the form of a "convex part" thru | or a "recessed part". For example, a “convex portion” such as a columnar shape, a conical shape, a prism shape, or a pyramid shape or a “concave portion” having a complementary shape may be formed on the sheet surface.

  6 is an example in which the sheet material 52 is constituted by an undulating sheet 92 having a plurality of ridges 90 formed on the surface thereof. In this example, the sheet material 52 is constituted by the liquid-permeable sheet 56 and the undulations (畝 90) are arranged on the surface of the sheet material 52 so as to be substantially orthogonal to the longitudinal direction (vertical direction in the drawing) of the sheet material 52. Has been. When the undulating sheet 92 is arranged so that its longitudinal direction coincides with the front-rear direction of the watery stool leakage prevention sheet, it is possible to inhibit liquid diffusibility in the front-rear direction of the watery stool leakage prevention sheet. .

  Furthermore, the watery stool leakage prevention sheet 160 shown in FIG. 7 is an example constituted by an undulating sheet 96 having a plurality of grooves 94 formed on the surface thereof. In this example, the sheet material 52 is constituted by the liquid permeable sheet 56 and the undulations (grooves 94) are arranged on the surface of the sheet material 52 so as to be substantially orthogonal to the longitudinal direction (vertical direction in the drawing) of the sheet material 52. Has been. When such an undulating sheet 96 is also arranged so that its longitudinal direction coincides with the front-rear direction of the watery stool leakage prevention sheet, it is possible to inhibit liquid diffusibility in the front-rear direction of the watery stool leakage prevention sheet. .

  The watery stool leakage prevention sheet 150 shown in FIG. 6 and the watery stool leakage prevention sheet 160 shown in FIG. 7 are examples in which the undulation sheets 92 and 96 are formed with only one of the ridges 90 or the grooves 94 to form undulations. However, those in which both ridges and grooves are formed are also included in the scope of the present invention. These sheets can be formed by a method such as a method of forming a ridge by attaching a convex member made of a nonwoven fabric to a nonwoven fabric sheet, or forming a groove by embossing the nonwoven fabric sheet.

  There are no particular restrictions on the form of the “ridges” or “grooves”. For example, examples of the cross-sectional shape of the ridges and grooves include a circle, a triangle, and a quadrangle. In the examples shown in FIGS. 6 and 7, the ridges 90 and the grooves 94 are continuously formed in the short direction of the sheet material 52, but the ridges and grooves are formed intermittently. It may be what has been done.

  Further, the watery stool leakage prevention sheet 170 shown in FIG. 8 is constituted by the undulation sheet 102 in which the sheet material 52 has a corrugated surface 98 on the surface, and a plurality of undulations are formed by the corrugated surface 98. This is an example. In this example, the sheet material 52 is constituted by the liquid-permeable sheet 56, and the surface of the sheet material 52 is a corrugated surface 98, and the undulation formed by the wave top portion 98a and the wave bottom portion 98b. It arrange | positions so that the longitudinal direction (drawing up-down direction) of the sheet | seat material 52 may be substantially orthogonal. When the undulating sheet 102 is arranged so that its longitudinal direction coincides with the front-rear direction of the watery stool leakage prevention sheet, it is possible to inhibit liquid diffusibility in the front-rear direction of the watery stool leakage prevention sheet. . The sheet material on which such a corrugated surface is formed can be obtained, for example, by a method of laminating a nonwoven fabric sheet that has been loosened in a wave shape on the surface of the nonwoven fabric sheet.

  8 is an example in which only one surface of the sheet material 52 is a corrugated surface 98, but when the entire sheet material 52 is corrugated, that is, the sheet Even when a corrugated sheet material is used as the material 52, undulations are formed on the sheet surface. Therefore, such a thing is also included in the scope of the present invention. Such a corrugated sheet material can be obtained, for example, by a method in which the surface of the frame material is processed into a corrugated shape, and a nonwoven fabric sheet is bonded to the surface of the corrugated frame material.

  Further, the watery stool leakage prevention sheet 180 shown in FIG. 9 is formed by the undulation sheet 106 in which a plurality of undulations are formed by the ridge 104 by bringing the ridge 104 to the sheet material 52 (that is, the sheet material 52 is creped). It is an example configured. In this example, the sheet material 52 is constituted by the liquid permeable sheet 56, and the ridge 104 is brought close to the sheet material 52, and the undulation formed by the ridge 104 is the longitudinal direction of the sheet material 52 (the vertical direction in the drawing). They are arranged so as to be substantially orthogonal. When the undulating sheet 106 is arranged so that the longitudinal direction thereof coincides with the front-rear direction of the watery stool leakage prevention sheet, it is possible to inhibit liquid diffusibility in the front-rear direction of the watery stool leakage prevention sheet. . The watery stool leakage preventing sheet 180 shown in FIG. 9 can be obtained, for example, by bringing the ridge 104 to the liquid permeable sheet 56 and making it into a crepe shape, and then sandwiching and fixing it with the frame material 54.

  In the watery stool leakage preventing sheet of the present invention, at least a part of the sheet material is constituted by a undulating sheet having a plurality of convex portions and / or concave portions formed on the surface thereof, and It is preferable that the leakage prevention sheet is disposed in a direction intersecting with the front-rear direction. By forming the undulation in this way, it is possible to more effectively inhibit the liquid diffusibility in the front-rear direction of the watery stool leakage prevention sheet, and from the end of the diaper (particularly the back end). Can be effectively prevented.

  The “crossing direction” means a direction that is not parallel to the front-rear direction of the watery stool leakage prevention sheet. From the viewpoint of reliably generating the effect of inhibiting the liquid diffusibility in the front-rear direction of the watery stool leakage prevention sheet, within a range of ± 45 ° with respect to the direction orthogonal to the front-rear direction of the watery stool leakage prevention sheet. The direction is preferably within a range of ± 30 °, and particularly preferably the direction perpendicular to the front-rear direction of the watery stool leakage prevention sheet. The watery stool leakage prevention sheets 150, 160, 170, and 180 shown in FIGS. 6 to 9 are all disposed so that the undulations are substantially orthogonal to the front-rear direction of the watery stool leakage prevention sheet. This is preferable in that the effect of inhibiting the diffusibility of the liquid in the front-rear direction of the prevention sheet is excellent.

  In the watery stool leakage preventing sheet of the present invention, it is preferable that the sheet material is constituted by a water-disintegrating sheet. “Water-breakable sheet” means a sheet material that has a strength that does not break even when wet, but disintegrates in a large amount of water and is finely pulverized. A spunlace nonwoven fabric in which fiber pieces are entangled with each other can be exemplified. The spunlace nonwoven fabric has a strength that does not break even when wet with water. However, when it is passed through a flush toilet, the entangled fiber pieces are loosened and collapsed in a large amount of water, and are finely crushed. When a sheet material is constituted by such a water-disintegrating sheet, even when solid stool is excreted on the surface of the sheet material, the solid stool can be discarded together with the water-disintegrating sheet in the toilet. Therefore, there is an advantage that it is possible to reduce time and effort at the time of disposal.

  Thus, when the sheet material is constituted by a water-disintegrating sheet, an annular score line is formed in the region surrounded by the frame material of the water-disintegrating sheet to cut out at least a part of the region. It is preferable to keep it. By forming the annular score line, it becomes possible to break the score line and cut out at least a part of the water-breakable sheet. With such a configuration, the watery stool leakage preventing sheet main body and the stool adhering portion can be easily separated, and the time and labor for disposal as described above can be further reduced.

  “Cut line” means a cut that penetrates a sheet formed to facilitate the breaking of the sheet. Specifically, in addition to a perforation, a cut called a “zipper” has a bowl shape. Examples include bent opening break lines (see page 281 of the well-known and commonly used techniques in the packaging industry, issued by the Japan Patent Office on December 20, 1978). The perforation may be a perforation formed in a double line shape.

  The term “annular” means a shape in which lines are connected continuously or intermittently so as to define a certain region, and several straight lines and / or curves are connected continuously or intermittently. Shapes are included. For example, a substantially rectangular shape, a substantially oval shape, an oval shape, a rectangular shape, a rhombus shape, a polygonal shape, and the like can be given.

  For example, the water-like stool leakage prevention sheet 190 shown in FIG. 10 includes the entire sheet material 52 constituted by the water-disintegrating sheet 62 and the region surrounded by the frame material 54 of the water-disintegrating sheet 62. This is an example in which an annular cut line 64 for cutting at least a part is formed. In this example, the water-breakable sheet 62 is a punching sheet in which an opening 66 is formed, and the entire sheet material 52 is configured as a liquid-permeable sheet 56. Further, perforations are employed as the annular cut lines, and the perforations are arranged in a substantially rectangular shape along the inner edge of the frame material 54.

  When the sheet material is constituted by a water-disintegrating sheet, the water-disintegrating sheet has a tab for peeling off at an edge thereof, and only one surface of the frame material is the frame material. It is preferable that it is stuck on the surface. Even in such a form, the water-disintegrating sheet can be easily peeled off from the frame material, and the time and effort for disposal as described above can be further reduced.

  For example, the watery stool leakage prevention sheet 200 shown in FIG. 11 includes the sheet material 52 as a whole by the water-disintegrating sheet 62, and has a tab 108 for peeling off at the edge of the water-disintegrating sheet 62. In this example, only one of the surfaces is attached to the surface of the frame material 54. In this example, the water-breakable sheet 62 is a punching sheet in which an opening 66 is formed, and the entire sheet material 52 is configured as a liquid-permeable sheet 56.

  In the water-like stool leakage prevention sheet of the present invention, the sheet material does not have to be composed of a single sheet material. Specifically, a plurality of sheet materials may be individually attached to the frame material, or a plurality of sheet materials joined together or laminated may be used as the liquid permeable sheet.

[1-2] Frame material:
The frame material is a reinforcing material attached so as to surround the outer edge of the sheet material. With this frame material, the strength of the water-like stool leakage prevention sheet is ensured, and it is possible to attach a water-like stool leakage prevention sheet so as to follow the surface side of the top sheet of the disposable diaper that deforms in various ways Become.

  The frame material is attached so as to surround the outer edge of the sheet material. This “enclose” means that the frame material 54 is attached so as to completely surround the outer edge of the sheet material 52 as in the water-like fecal leakage prevention sheet 210 shown in FIG. Like the watery stool leakage prevention sheet 100 shown, the frame material 54 is attached so that the outer edge of the sheet material 52 coincides with the outer edge of the frame material 54, or the watery stool leakage prevention sheet 220 shown in FIG. 14, the outer edge of the sheet material 52 does not coincide with the outer edge of the frame material 54, but the frame material 54 is attached along the outer edge of the sheet material 52. It is also a concept that encompasses some forms. Usually, since a sheet material formed in a rectangular shape is often used, it is preferable to arrange the frame material in a rectangular shape according to the shape.

  Further, “enclose” does not necessarily require that all the frame materials are continuously constructed or arranged, and the watery stool leakage preventing sheet 220 shown in FIG. 13 or the watery stool leakage preventing sheet 230 shown in FIG. As described above, as long as a certain region is defined by the frame material 54, it may be configured or arranged discontinuously or intermittently. In the water-like stool leakage prevention sheet 220 shown in FIG. 13, four frame members 54 are arranged along the four sides of the rectangular sheet member 52, and the frame member 54 is formed at the four apexes of the rectangle. In this example, the discontinuity 70 is formed. Further, the water-like stool leakage preventing sheet 230 shown in FIG. 14 has a frame material 54 arranged in a substantially rectangular shape along the four sides of the rectangular sheet material 52, and has two long sides of the rectangle. In this example, the frame material 54 is discontinuous in a part and the discontinuous portion 70 is formed.

  As shown in the water-like stool leakage prevention sheet 220 shown in FIG. 13, four frame members 54 are arranged along the four sides of the sheet member 52 formed in a rectangular shape, and the frame member is formed at the four apexes of the rectangle. When 54 is discontinuous and the discontinuous portion 70 is formed, it becomes easy to store the watery stool leakage preventing sheet on the lower surface side of a three-dimensional gather such as a diaper or a urine pad, and thus the watery stool leakage preventing sheet can be easily attached. There is an advantage that In addition, fixing the water-like stool leakage preventing sheet on the lower surface side of the three-dimensional gather is also preferable in that the water-like stool leakage preventing sheet is less likely to be displaced when a diaper or the like is worn.

  It is also preferable to arrange a frame material having a rectangular frame shape along the four sides of the sheet material formed in a rectangular shape, and to cut off a part of the four vertex portions. For example, the water-like stool leakage prevention sheet 240 shown in FIG. 15 has a rectangular frame-shaped frame material 54 disposed along the four sides of the rectangular sheet material 52, and a part of the four apexes is cut off. In this example, an L-shaped cutout 72 is formed. The cutout portion 72 makes it easy to store the watery stool leakage preventing sheet on the lower surface side of a three-dimensional gather such as a diaper, and thus facilitates the attachment of the watery stool leakage preventing sheet. Moreover, there exists an effect that a watery feces leak prevention sheet becomes difficult to slip | deviate at the time of wearing of a diaper etc.

  In the watery stool leakage preventing sheet of the present invention, the frame material is attached so that the surface thereof protrudes from at least one surface of the sheet material, and at least one surface of the sheet material and the surface of the frame material A step of 2 to 20 mm is preferably formed between the two. By forming a step within such a range, a certain space is formed between the sheet material (and hence the skin of the wearer) and the top sheet of the diaper. The effect is demonstrated. On the other hand, if the step is less than 2 mm, the formed space is too narrow, and the effect may be insufficient. Moreover, when it exceeds 20 mm, it will become difficult to fit under the three-dimensional gathers, such as a diaper, and there exists a possibility that the leak-proof effect of three-dimensional gathers, such as a diaper, may be reduced. Moreover, a feeling of wear and fit may fall. In order to ensure the above effects, it is more preferable that the step is 5 to 10 mm.

  In the watery stool leakage preventing sheet of the present invention, it is preferable that the frame material has a roughened surface on the side protruding from at least one surface of the sheet material. With such a configuration, the coefficient of friction between the top sheet surface of the disposable diaper and the frame material (and consequently the watery stool leakage prevention sheet) is increased, and the watery stool leakage prevention sheet is displaced inside the diaper due to the movement of the wearer. Can be effectively prevented. “Roughening” includes all of making the surface of the frame material not smooth. For example, the surface of the frame material may be uneven, or the surface of the frame material may be corrugated.

  In order to ensure the above functions, the frame material is preferably made of a material that is flexible and has some stiffness. For example, a material made of a material such as felt, urethane foam, air laid nonwoven fabric, or resin such as polyethylene resin can be suitably used.

  The frame material preferably includes a fastening member that can be fixed to another absorbent article. By providing the fastening member, the watery stool leakage prevention sheet can be reliably fixed to a diaper, a urine pad, or the like, and leakage of watery stool due to misalignment can be effectively prevented. Examples of the fastening member include an adhesive fastener and a mechanical fastener. Among these, a mechanical fastener that can be surely fixed and can withstand repeated use is preferable.

  Moreover, it is preferable that the water-like stool leakage prevention sheet | seat of this invention comprises at least one part of a frame material with the hook material of a mechanical fastener. The hook material is a convex member in which a large number of protrusions (such as bowls, mushrooms, bowls, etc.) are formed on the surface of the resin sheet. It can be used suitably. The hook material can be engaged with a concave material (loop material) in which loop-shaped fibers are arranged, or a sheet material made of a material having a fibrous surface such as woven fabric, non-woven fabric, felt, or pile. The member can be firmly fixed in a peelable state. Therefore, by engaging the hook material constituting a part of the frame material with the disposable diaper, the top sheet of the urine pad, etc., the situation where the watery stool leakage prevention sheet is displaced inside the diaper etc. and does not perform its function. It can be effectively prevented.

  As already described, the frame material is arranged so as to surround the outer edge of the sheet material, and when the sheet material is formed in a substantially rectangular shape, the frame material is attached along the four sides of the sheet material. It is preferable. And when at least one part of a frame material is comprised with the hook material of a mechanical fastener as mentioned above, it is preferable that the hook material is attached along two long sides among the four sides of a sheet | seat material. .

  With the configuration as described above, it is possible to prevent “twisting” in the central portion in the longitudinal direction of the watery stool leakage prevention sheet, and it is effective for the situation where the watery stool leakage prevention sheet crawls inside the diaper and does not perform its function. Can be prevented. For example, the watery stool leakage prevention sheet 220 shown in FIG. 13 is an example in which the frame material 54 is provided along the four sides of the substantially rectangular sheet material 52, and the hook material 68 is provided along the two long sides. is there. However, even when hook members 68 are provided along two short sides of the four sides of the substantially rectangular sheet material 52 as in the water-like stool leakage prevention sheet 230 shown in FIG. Can be engaged with a diaper, a top sheet of a urine pad, or the like, and “displacement” inside the diaper of a watery stool leakage prevention sheet can be prevented.

  Moreover, the water-like stool leakage prevention sheet of this invention may be equipped with frame materials other than what is attached so that the outer edge of a sheet material may be enclosed as a frame material. The sheet material is formed in a substantially rectangular shape, and as the frame material, the outer edge frame material provided along the four sides of the sheet material and the outer edge frame material arranged along the two long sides of the four sides are connected to each other. It is preferable that the bridge frame material spanned as described above is provided, and the region surrounded by the outer frame material is divided into two regions by the bridge frame material.

  For example, the water-like stool leakage prevention sheet 110 shown in FIG. 2 includes a rectangular frame-shaped outer edge frame material 54a attached along the four sides of the sheet material, the sheet material 52 being formed in a rectangular shape, and the frame material 54. A bridging frame material 54b is provided so as to connect the central portions of the outer edge frame material 54a arranged along two long sides of the four sides. In this example, the rectangular region surrounded by the outer frame material 54a is divided into two regions by the bridging frame material 54b.

  In the configuration as described above, since the sheet material is divided into two regions, the liquid permeable sheet is disposed only in one region, and the sheet material having another function is disposed in the other region. Is possible. Therefore, in the watery feces leakage prevention sheet of the present invention, the liquid-permeable sheet is disposed in one of the two regions, and the liquid-impermeable sheet or water-repellent sheet is disposed in the other region. More preferably.

  For example, in the watery stool leakage prevention sheet 110 shown in FIG. 2, the sheet material 52 is divided into two regions at the cross-linked frame material 54 b, and the liquid-permeable sheet 56 is disposed only in the upper region of the drawing, This is an example in which a water-repellent sheet 60 is disposed in the lower region of the drawing. If such a watery stool leakage prevention sheet is arranged so that the area where the liquid-permeable sheet is arranged is the rear side of the diaper, and the area where the liquid-impermeable sheet or the water-repellent sheet is arranged is the front side of the diaper, On the hip side of the wearer, the excreted watery stool passes through the watery stool leakage prevention sheet and flows into the space between the top sheet and the watery stool leakage prevention sheet, while on the wearer's stomach side, the sheet is removed. It is difficult for watery stools to reverse. Therefore, it is possible to effectively prevent watery stool from adhering to male and female genitals, which is very hygienic.

  In the water-like stool leakage prevention sheet 110 shown in FIG. 2, the liquid-permeable sheet 56 and the water-repellent sheet 60 are divided at the portion of the crosslinked frame material 54b, but at a portion other than the portion of the crosslinked frame material, Even if the liquid permeable sheet is separated from the liquid impermeable sheet or the water repellent sheet, the same effect can be obtained. That is, the position of the cross-linking frame material and the position where the liquid permeable sheet and the liquid impermeable sheet are divided are also included in the scope of the present invention.

  Furthermore, the water-like stool leakage preventing sheet of the present invention is such that the sheet material is formed in a substantially rectangular shape, the frame material is disposed along four sides of the sheet material, and two of the sheet materials among the frame materials. It is preferable that a groove or a weakening line is formed at the center in the longitudinal direction of the portion arranged along the long side so as to cross the frame material.

  With this configuration, it is possible to fold the watery stool leakage prevention sheet in a folded state at the time of sale and wrap it in a compact state. Therefore, it is possible to effectively prevent a situation in which the water-like stool leakage prevention sheet is attached with the surface on the side where the frame material overhangs up.

  The shape of the groove is not particularly limited as long as the sheet can be easily bent, and examples of the shape of the groove include a semicircular shape, a triangular shape, and a quadrangular shape. For example, a watery stool leakage prevention sheet 250 shown in FIG. 16 has a sheet material 52 formed in a substantially rectangular shape, and a frame material 54 arranged along four sides of the sheet material 52. This is an example in which a concave groove 74 having a triangular cross section is formed so as to cross the frame material 54 at the center in the longitudinal direction of the portion arranged along the two long sides of the sheet material 52.

[1-3] Others:
The water-like stool leakage prevention sheet of the present invention may be provided with a three-dimensional gather along the edge of the sheet material. By such a configuration, even if the watery stool spreads along the surface of the watery stool leakage prevention sheet, the three-dimensional gathering becomes a breakwater, and from the end of the diaper (especially the back end) Can be effectively prevented.

  The three-dimensional gather is a member for preventing the wearer's excrement from leaking, and is a leak-proof wall configured to stand up three-dimensionally. The structure of a three-dimensional gather can employ | adopt the structure used for the conventional disposable diaper and other absorbent articles. For example, it is possible to suitably use a material in which a stretchable material (a three-dimensional gathered stretchable material) is arranged on a part of the sheet material, and a gather is formed on the sheet material by the three-dimensional gathered stretchable material.
