Description

  The present invention relates to an incontinence pad (including a “urine collection pad”) that is used with, for example, a disposable diaper or alone and absorbs and retains body fluids such as urine.

For example, a conventional incontinence pad is configured as follows.
In general, the incontinence pad is used by a user who is worried about leakage of urine by wearing it on the lower body during daily life, that is, when he / she is awake and acting at night, or during nighttime sleeping.
For this reason, the incontinence pad has a liquid-impermeable sheet material applied to a portion that becomes an outer surface when the user wears it, and an absorbent material for absorbing liquid such as urine is disposed inside the incontinence pad. ing.

FIG. 8 shows a conventional incontinence pad. The incontinence pad 1 is mainly inserted inside a paper diaper or underwear, so that the incontinence pad 1 has a shape that is long in the front-rear direction so that the excretory organ of the user can be covered in a state worn by the user. ing.
A liquid impervious back sheet 2 is used at a portion that becomes the outer surface of the incontinence pad 1. Inside the back sheet 2 is accommodated an absorber 4 for absorbing liquid such as urine. A surface material 5 is disposed further inside the absorber 4. The surface material 5 is made of a material that passes liquid. The surface material 5 and the back sheet 2 are disposed so as to overlap each other at the outer peripheral portion, and two three-dimensional gather portions 6 and 6 are provided inside the surface material 5. A crotch gather portion 7 is provided outside the three-dimensional gather portion 6. The three-dimensional gather portion 6 and the crotch gather portion 7 surround the user's crotch when the user wears the incontinence pad 1 so that liquid such as urine does not flow outside the incontinence pad 1. It prevents the underwear from getting dirty.

  For this reason, the incontinence pad 1 has a shape that is long in the front-rear direction in FIG. 8, and the three-dimensional gather portion 6 and the crotch gather portion 7 are located in the user's inseam in the mounted state, and the one end portion 8 is the body. The other end 9 is located on the front side of the body so as to cover the excretory organs and the genital area. The outer surface 12 of the incontinence pad 1 is formed with a misalignment-preventing adhesive portion 11 that is exposed when the release paper 13 is peeled off. The adhesive portion 11 temporarily attaches the inner surface of a paper diaper or underwear. It can be fixed.

By the way, the incontinence pad 1 as described above is used as a countermeasure against incontinence, for example, as described above, inside the paper diaper or underwear, and used as a single incontinence pad 1 in addition to the following. May be used as well.
For example, in the field of nursing care, the frequent change of the diaper of a caregiver who wears a paper diaper, especially at night, is due to restrictions on human resources or the fact that the caregiver is sleeping It is relatively difficult. For this reason, the incontinence pad 1 that can be easily exchanged is further stacked on the inner side of the diaper (not shown), and the diaper and incontinence are absorbed by the incontinence pad 1 and the absorbent capacity of the paper diaper after the caregiver goes to bed. The pad 1 can be used without being changed until morning. Here, the incontinence pad for supplementing the absorption power of such diapers is sometimes called a urine collecting pad.

However, there are the following problems at the time of simultaneous use with diapers in the field of such care.
As described above, when the incontinence pad 1 is attached to the inside of the paper diaper and the cared person urinates after going to bed, if the amount or frequency of urination is large, the absorbed amount of the incontinence pad 1 may not be exceeded. , May overflow.

That is, the incontinence pad 1 is formed smaller than a paper diaper, has a small amount of absorber, and has a small capacity for absorption. In addition, since the incontinence pad 1 has a waterproof buckle 2 on the outside, the discharged urine does not penetrate into the paper diaper immediately below the incontinence pad 1 and passes through the gap between the three-dimensional gather 6 and the crotch gather 7 and There is a problem that the urine is not transmitted to the absorbent part of the paper diaper as it is and leaks from the crotch part of the paper diaper to the side.
In particular, since the incontinence pad 1 can be frequently replaced during the daytime, it is worth using the incontinence pad 1 because it reduces the replacement work. However, it is difficult to replace at night, and the above-described leakage is likely to occur. .

  Therefore, the present invention can be used as a single body, and when used at the same time as the diaper inside the diaper, the diaper absorber absorbs the excretion liquid exceeding the absorbed amount, thereby making it difficult to leak to the side. The purpose is to provide an incontinence pad that does not leak out.

  According to the first aspect of the present invention, the whole has a shape that is long in one direction, the back sheet that prevents the permeation of the liquid, and the liquid permeable that is disposed on the surface side that contacts the body. A surface material and an absorber disposed between the back sheet and the surface material to absorb and hold the liquid that has passed through the surface material, and the back sheet exposes the absorber. This is achieved by an incontinence pad comprising an opening forming means for forming the opening to be made.

According to the configuration of claim 1, the incontinence pad of the present invention has a basic shape that is long in one direction by laminating and fixing a plurality of sheet-like materials. The backsheet prevents liquid permeation. The said surface material is a liquid-permeable thing arrange | positioned at the surface side which contacts a body. The absorber is disposed between the back sheet and the surface material to absorb and hold the liquid that has permeated the surface material.
The opening forming means which is a characteristic part of this configuration is capable of forming an opening as necessary with respect to the liquid-impermeable back sheet. That is, normally, an opening is not formed in the back sheet, and means for forming the opening based on the operation is provided as required by the user.
As a result, when the incontinence pad is used as a single body, no opening is formed in the back sheet, and when body fluid such as urine is discharged, the liquid is held by the absorbent body of the incontinence pad. , The outside from the back sheet is prevented.

On the other hand, when the incontinence pad is used inside a diaper such as a paper diaper and used together with the diaper, the opening forming means is operated to previously form an opening in the back sheet. Thereby, for example, even when a large amount of urine is discharged and exceeds the amount absorbed by the incontinence pad, the urine that cannot be held by the incontinence pad absorber is removed from the opening, and the surface material of the paper diaper directly below Is absorbed through. This effectively prevents urine that has not been absorbed by the incontinence pad from leaking out from the side.
The “incontinence pad” according to the present invention refers to any absorbent product having the structure of claim 1 and intended to absorb bodily fluids discharged from the human body. It doesn't matter. For example, the “incontinence pad” according to the present invention is temporarily fixed to the inside of an underwear or the like as a measure against light incontinence, and is disposed inside a paper diaper as well as the incontinence pad used, or used alone. A urine collecting pad or the like as a pad is also included.

According to a second aspect of the present invention, in the configuration of the first aspect, the opening forming means is formed in a substantially central region in the longitudinal direction of the backsheet.
According to the configuration of claim 2, in the incontinence pad having a shape that is long in one direction, a drainage organ that discharges human urine and the like by being formed in a substantially central region with respect to the longitudinal direction of the backsheet. Since an opening can be formed near the urine, an opening can be provided at a place where urine or the like is most likely to leak.

According to a third aspect of the present invention, in the configuration of the first aspect, the opening forming means is a substantially central region with respect to the longitudinal direction of the backsheet and is formed slightly behind. .
According to the configuration of claim 3, in the incontinence pad having a shape that is long in one direction, the wearer has slept because it is formed slightly behind the substantially central region with respect to the longitudinal direction of the backsheet. In the state, when there is urination or the like, it is absorbed from the opening to the diaper side before leaking in the back direction, and it is possible to effectively prevent the back from being turned around.

According to a fourth aspect of the present invention, in the configuration of the second aspect, the opening forming means is a substantially central region with respect to the longitudinal direction of the backsheet, and the openings are formed in the vicinity of both ends of the absorbent body in the short direction. It is provided as follows.
According to the configuration of the fourth aspect, since the opening can be formed at a position corresponding to the crotch portion where the urine of the incontinence pad easily leaks, the urine is absorbed into the incontinence pad until it cannot be absorbed and leaks from the crotch portion. Immediately before, the urine flows from the opening to the diaper side, so that the amount of absorption of the incontinence pad can be used sufficiently, especially urine leaks from the side of the incontinence pad, and this leaks out from the crotch of the diaper. Can be effectively prevented.

According to a fifth aspect of the present invention, in the configuration according to any one of the first to fourth aspects, a water-permeable cover member is disposed between the back sheet and the absorbent body at least in a region where the opening forming means is provided.

BEST MODE FOR CARRYING OUT THE INVENTION

DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described in detail with reference to the accompanying drawings.
Note that the embodiments described below are preferred specific examples of the present invention, and thus various technically preferable limitations are given. However, the scope of the present invention is particularly limited in the following description. Unless otherwise stated, the present invention is not limited to these forms.

1 and 2 show an incontinence pad according to the first embodiment of the present invention. The incontinence pad 20 is substantially the same as the incontinence pad 1 described in FIG. It consists of.
FIG. 1 is a schematic plan view of the incontinence pad 20, and FIG. 2 is a schematic cross-sectional view taken along line AA of FIG.
In FIG. 1, the direction displayed as “front” is the front side of the body when worn. FIG. 1 is drawn with the outside of the incontinence pad 20, that is, the back seat side facing forward.

1 and 2, the incontinence pad 20 includes a back sheet 22, an absorber 24, a surface material 25, left and right three-dimensional gather portions 26, and left and right crotch gather portions 27. The left and right three-dimensional gathers 26 and 26 do not appear in FIG. 1 because they stand upright behind the page.
The back sheet 22 is an outer sheet material, and is made of a material that prevents liquid from permeating. As a material of the back sheet 22, for example, a thin plastic film, specifically, a polyethylene film or polyethylene laminated paper can be used. The back sheet 22 does not allow liquid to pass through, but is preferably selected from a material that can permeate water vapor to prevent stuffiness and has some degree of flexibility. As a result, the contents inside the incontinence pad 20 (solid matter such as filth, urine, blood, etc.) do not leak to the outside.

The absorber 24 is disposed and accommodated between the back sheet 22 and the surface material 25, and is constituted by a tissue or an absorption holding layer, and is a portion for absorbing and holding a liquid or the like. .
Tissue is a soft material that absorbs liquid, such as pulp (virgin pulp, recycled recycled pulp), rayon, cotton, kenaf, bagasse, silk, hydrophilic treated fibers (polyolefin, polyester, acrylic), etc. A composite sheet can be used.
The absorption holding layer plays a role of absorbing and holding the liquid component that has passed through the center surface material 28 of the surface material 25. Therefore, any material having excellent liquid absorbability can be used. As the material of the absorber 24, for example, a polymer which is an absorbent material is mixed with pulp, or a polymer is sprayed onto pulp. The pulp absorber or polymer to be formed is preferred. Here, the pulp is an aggregate of cellulose fibers extracted, for example, by mechanically or chemically treating wood, and a pulp-like material is used. Here, the absorbent body 24 is configured as a single sheet. However, the absorbent body 24 may be formed so as to cover the absorbent holding layer with a tissue, or a plurality of absorbent bodies 24 may be laminated.

  The surface material 25 has a center surface material 28 and two side surface materials 29 and 30. The center surface material 28 is a portion that is fixed to the absorber 24 and the backsheet 22 by an adhesive along the longitudinal direction L (see FIG. 1), and the center surface material 28 directly touches the user's skin. Therefore, a material suitable for this is selected in consideration of a good touch without damaging the skin more than necessary. The center surface material 28 is also called an inner sheet or a top sheet, and as a fiber of a material suitable for allowing a liquid to permeate and a liquid component to permeate quickly, for example, various natural fibers, synthetic fibers or these fibers can be used. You can choose from combinations. For example, as a synthetic fiber, for example, a fiber formed from polyester or polypropylene fiber so as to improve liquid permeability is preferable.

The side surface materials 29 and 30 are arranged on both sides of the center surface material 28 along the longitudinal direction L of the center surface material 28. The center surface material 28 can transmit the liquid, whereas the side surface materials 29 and 30 are made of a material that prevents the liquid from transmitting. For example, when the center surface material 28 is made of non-woven fabric, for example, wet non-woven fabric (paper, tissue, hydrospun (Dexter), chemical bond (or resin bond), thermal bond (embossed, anvil, air-through), airlaid , Spunlace, spunbond, meltblown, needle punch, stitchbond, and SM nonwoven fabric (spunbond and meltblown laminate), SMS nonwoven fabric (spunbond and meltblown and spunbond) The center surface material 28 is particularly preferably a thermal bond, a spunbond, or a spunlace.
Examples of the material of the side surface materials 29 and 30 include a polyolefin nonwoven fabric or a combination of a polyester nonwoven fabric and a thin plastic film, a combination of a polyester nonwoven fabric and a polyethylene film, an SM nonwoven fabric, an SMS nonwoven fabric, etc. Can be adopted.

The left and right three-dimensional gather portions 26 and 26 are formed by disposing an elastic body 55 at least in the center portion in the longitudinal direction of the side surface materials 29 and 30, respectively. In the illustrated example, the three-dimensional gathered portion 26 is formed by disposing an elastic body at least in the center portion in the longitudinal direction L of the side surface material 30.
In order to form the three-dimensional gathered portion 26, the linear elastic body 55 is accommodated along the longitudinal direction L at least in the central portion of the side surface material 29 or the side surface material 30. Due to the elastic contraction ability of the elastic body 55, as shown by the arrow in FIG. 2, the three-dimensional gathered portion 26 stands up at the center of at least the side surface materials 29 and 30. By forming the three-dimensional gather portion 26, the excrement or liquid component of the user is closely adhered to the user's body so as not to leak outward along the short direction T of the incontinence pad 20.
The crotch gather portion 27 cooperates with the three-dimensional gather portion 26 to improve the fit of the user to the crotch by pulling both ends in the short direction corresponding to the crotch of the incontinence pad 20 with the elastic force of the elastic body 55. Prevents user excretion or liquid components from leaking out of the crotch.

Furthermore, the structure of the side surface materials 29 and 30 will be described in detail with reference to FIG.
In FIG. 2, the side surface material 29 and the side surface material 30 each contain an elastic body 55 for forming the three-dimensional gather portion 26. The elastic body 55 is accommodated by bending the inner ends 54 of the side surface materials 29 and 30 into a bag shape. The inner end 54 is integrally fixed to the side surface materials 29 and 30 by using, for example, heat sealing. The elastic body 55 is made of, for example, a linear elastic material, specifically, rubber or a film-like elastomer, and is accommodated in the bag-shaped portions of the side surface materials 29 and 30.
In addition, although the contact part of another members, such as a back seat | sheet and a side surface material, is basically adhere | attached by hot melt, the display is abbreviate | omitted for simplification of drawing.

  As shown in FIG. 1, slippage preventing release papers 31 and 32 are pasted on the back sheet 22 in the vicinity of both ends in the longitudinal direction of the incontinence pad 20. When the release sheets 31 and 32 are peeled off, temporary fixing portions using an adhesive are exposed below, and the temporary fixing portions are temporarily fixed to the inner surface of the user's underwear, so that the incontinence pad 20 is displaced. There is no such thing.

Further, in the present embodiment, in FIG. 1, the opening forming means 40 is provided in the central region, in the illustrated case, slightly behind the center in the longitudinal direction L of the incontinence pad 20. Yes. By operating the opening forming means 40 as will be described later, the opening 41 is provided in the back sheet 22 positioned below the opening forming means 40.
The opening forming means 40 will be described in more detail later.

FIG. 3 is a schematic cross-sectional view showing a state in which the incontinence pad 20 is used while being overlapped with a diaper. In this case, for example, a paper diaper 50 is used as the diaper.
The paper diaper 50 is larger than the incontinence pad 20, but a paper diaper 50 having substantially the same configuration as the incontinence pad 20 can be used.
That is, the paper diaper 50 includes a back sheet 52, an absorber 53, a surface material 55, left and right three-dimensional gather portions 56 and 56, and left and right crotch gather portions 57 and 57.
The incontinence pad 20 is placed so that the opening 41 is exposed by the above-described opening forming means 40 and the opening 41 is opposed to the center surface material 58 of the diaper 50 as shown in the figure. In this case, the release papers 31 and 32 for preventing the displacement of the incontinence pad 20 described in FIG. 1 may be peeled off and fixed to the surface material 28 of the diaper 50.

  Thereby, as will be described later, a large amount of excreted liquid such as urine discharged by the user passes through the absorbent body 24 through the incontinence pad 20 and is absorbed by the absorbent body 53 of the diaper 50 through the opening 41. It has come to be. This point will be described in detail later.

FIG. 4 is an enlarged perspective view for explaining the configuration of the opening forming means 40. The opening forming means 40 will be described in detail with reference to FIGS.
The opening forming means 40 is for forming the opening 41 on the outer surface of the backsheet 22 and is closed when the incontinence pad 20 is used alone.
As described with reference to FIG. 3, the opening 41 is exposed when the incontinence pad 20 is used over the diaper 50.

  Specifically, as shown in FIG. 4, the breaking guide portion 44 is formed so as to define the opening 41 of the backsheet 22 corresponding to the opening 41. The fracture guide portion 44 is a location where stress concentrates when the opening forming means 40 attempts to form the opening 41. That is, the break guide part 44 is a means for cutting out a part of the backsheet 22 to easily form the opening 41, and in the present embodiment, the holes are continuously formed along the opening 41. That is, the breaking guide portion 44 is provided by forming a large number of holes arranged like perforations in the shape of an ellipse or an ellipse as illustrated. However, in this case, as shown in FIG. 2, each continuous hole has a bottom of the hole without passing through the back sheet as perforated. Thus, the hole may be shaped like a continuous groove when continued along the opening 41. That is, the hole is formed in the back sheet and has a shape like a hole or a groove that does not penetrate the back sheet. Accordingly, when the incontinence pad 20 is used alone and the opening 41 is not formed, the liquid does not leak out from the absorber 24 through the hole.

  In addition, a water-permeable cover member 43 is disposed between the back sheet 22 and the absorber 24 at a position located on the back side of the opening 41 while being bonded to the absorber 24 or the back sheet 22. This water-permeable cover member is used to prevent liquid from penetrating the liquid, but, for example, the absorbent polymer from the outside from the absorber 24 side, and has such a function. Any form may be used as long as it is not limited to the periphery of the opening 41 and may be provided on the entire surface between the back sheet 22 and the absorber 24. In the case of this embodiment, a water-permeable sheet 43 is used as the water-permeable cover member. As this water-permeable sheet 43, the material similar to a center surface material can be used.

  Furthermore, the opening forming means 40 has a peeling sheet 42 that is pasted so as to cover the opening 41 from the outside of the back sheet 22. The release sheet 42 itself is not of a special configuration, and widely used release papers can be used except that the release sheet 42 is formed of a material that does not transmit moisture. For example, when the peeling sheet 42 is pulled and peeled in the direction of arrow B in FIG. 4, a part of the back sheet 22 under the peeling sheet 42 is cut along the above-described breaking guide portion 44, and the cut portion 22 a is formed. The opening 41 is formed by removing the adhesive sheet 42 from the peeling sheet 42 side. That is, a portion corresponding to the cut portion 22a of the back sheet 22 is firmly bonded to the peeling sheet 42 in advance.

  Further, an adhesive portion 45 bonded to the water-permeable sheet 43 is provided on the inner surface side of the end portion on the peeling direction (arrow B direction) side of the periphery of the opening 41 of the backsheet 22. Thereby, when the peeling sheet 42 is peeled as shown in FIG. 4, the adhesive portion 45 of the back sheet 22 is fixed to the water-permeable sheet 43 side when the cut portion 22 a is cut off. The opening 42 is prevented from being broken by being pulled by the sheet 42 and tearing.

  Furthermore, in order to ensure such an effect, the back sheet 22 is preferably formed so that the plastic film for forming the back sheet 22 coincides with the longitudinal direction of the incontinence pad 20, that is, the peeling direction B in FIG. It is made of a stretched material. As a result, the back sheet 22 is easily broken in the direction of the peeling direction B, and is not pulled by being pulled by the peeling sheet 42. Even when the back sheet 22 is formed of a biaxially stretched film, the same effect can be obtained by using a material that is more strongly stretched in the direction corresponding to the peeling direction B.

This embodiment is configured as described above, and when the incontinence pad 20 is used alone, it has the same function as a normal incontinence pad unless the peeling sheet 42 of the opening forming means 40 is peeled off. Therefore, the underwear can be used so as not to be stained due to urinary incontinence or the like, or used in combination with the paper diaper 50 in the daytime, and can be used as it is to reduce the diaper changing work.
In particular, in the field of nursing or the like, as described with reference to FIG. 3, the incontinence pad 20 is further overlapped on the inside of the paper diaper 50, so that the diaper 50 can be used after the caregiver goes to bed. Since the amount of absorption of the incontinence pad 20 is added to the amount of absorption, there is no need to replace the diaper 50 until morning, so that the caregiver's sleep is not disturbed and the burden on the caregiver can be reduced.

Specifically, when a user such as a care recipient wears the diaper 50 at bedtime, not only the diaper 50 but also the incontinence pad 20 is put on the inside as shown in FIG. The
In this case, by pulling the peeling sheet 42 described in FIG. 4 in the direction of arrow B, the opening 41 is exposed on the outer surface of the back sheet 22 of the incontinence pad 20, and the opening 41 faces the surface material 55 of the diaper 50. Arranged in a state.

  By using the one arranged in the diaper 50 with the opening 41 of the incontinence pad 20 opened before going to bed, the amount of absorption exceeding the amount of urine excreted until morning is ensured, and the burden associated with exchanging diapers at night is guaranteed. Can be reduced.

  Thus, when a large amount of urine is discharged during night use and exceeds the amount absorbed by the incontinence pad 20, or when the discharge speed of urine is extremely fast, the discharged urine is shown in FIG. The urine that has not been absorbed after being absorbed by the absorbent body 24 through the surface material 25 of the incontinence pad 20 hardly retains in the portion above the surface material 25, and a large amount of urine has the opening 41. To the absorber 53 through the surface material 55 of the diaper 50.

As a result, the urine temporarily staying in the portion above the surface material 25 of the incontinence pad 20 flows to the side, beyond the three-dimensional gathers 26 and 26 and the crotch gathers 27 and 27, and further beyond the diaper 50. Thus, it is possible to effectively prevent the leakage from the vicinity of the user's crotch.
Alternatively, the urine temporarily staying in the upper part of the surface material 25 of the incontinence pad 20 will turn to the back of the user who is sleeping while sleeping. In this embodiment, incontinence is shown in FIG. With respect to the longitudinal direction L of the pad 20, an opening forming means 40 is provided in a central region, in the illustrated case, a position located slightly behind the center. In the opening forming means 40, since the opening 41 is formed in advance as described above, the opening 41 is prepared corresponding to the position where urination is performed. The absorbent body 24 of the pad 20 is transmitted and absorbed by the diaper 50 through the opening 41.

  In addition, in the incontinence pad 20 of this embodiment, when the opening 41 is not formed by operating the opening forming means 40 as described above, that is, when the peeling sheet 42 is not peeled off, Since there is no opening and it is sealed, as it is with the conventional incontinence pad 20, it is used as it is to absorb urinary incontinence by attaching it to underwear, and in the daytime, it is used together with a paper diaper.

FIG. 5 is a plan view showing a second embodiment of the incontinence pad of the present invention. In the figure, the portions denoted by the same reference numerals as those in the first embodiment have a common configuration, and therefore, overlapping description will be omitted and differences will be mainly described.
In the figure, the incontinence pad 60 differs from the first embodiment only in the position and the configuration of the opening forming means 61.

Specifically, the opening forming means 61 is formed at a position corresponding to the crotch portion of the incontinence pad 60 in this embodiment. That is, the opening forming means 61 is formed in the center portion in the longitudinal direction L of the incontinence pad 60 and corresponding to the vicinity of both ends in the short direction perpendicular to the longitudinal direction L.
The opening forming means 61 has a large peeling sheet 62, and the other configuration is the same as the opening forming means 40 described with reference to FIG. 4 except for the peeling sheet 62. However, two common structures are provided. That is, one is provided at each position inside the left and right crotch gathers 27, 27 of the incontinence pad 60, and two openings 41-1, 41-2 are provided as shown in FIG. Yes. The structure around each of the openings 41-1 and 41-2 is the same as that described with reference to FIG.

  As a result, the two openings 41-1 and 41-2 are exposed in the back sheet 22 only by peeling one sheet 62, and the left and right crotch gathers 27 and 27 of the incontinence pad 60 are exposed. Each opening 41-1 and 41-2 are formed in the position inside.

The present embodiment is configured as described above, and can exhibit the same functions and effects as those of the first embodiment. In addition, since the openings 41-1 and 41-2 can be formed at positions corresponding to the crotch portion where the urine etc. of the incontinence pad 60 is easily leaked, a large amount of urine is absorbed in the incontinence pad, Immediately before leaking from the urine, urine begins to flow from the openings 41-1 and 41-2 to the diaper 50, so that the amount of absorption of the incontinence pad 60 can be sufficiently utilized. It can prevent effectively that it leaks and this leaks out from the crotch part of the diaper 50.
Of course, one release sheet may be provided for each of the openings 41-1 and 41-2.

FIG. 6 is a schematic cross-sectional view showing a third embodiment of the incontinence pad of the present invention. In the figure, the portions denoted by the same reference numerals as those in the first embodiment have a common configuration, and therefore, overlapping description will be omitted and differences will be mainly described.
In the figure, the incontinence pad 70 is partially different in configuration of the opening forming means 71 from the first embodiment.

The backsheet 22 of the incontinence pad 70 is provided with an opening forming means 71 at the same position as in the first embodiment or the second embodiment. In the case of FIG. 6, the same position as the first embodiment is provided. The case where it provides is shown in figure.
In this case, the opening 41 is formed in advance by removing the corresponding portion of the back sheet 22 inside the peeling sheet 72. The peeling sheet 72 has a larger area than the opening 41, covers the opening 41, and uses a waterproof material similar to the back sheet. As shown in the figure, the peeling sheet 72 is adhered by a seal portion 73 formed of a waterproof adhesive that completely surrounds the opening 41.

  As a result, the incontinence pad 70 of the present embodiment also exhibits the same effects as the first embodiment. In addition, when the incontinence pad 70 is used alone, the seal portion 73 completely seals the gap between the peeling sheet 72 and the back sheet 22, so that it is absorbed by the absorber 24 from the surface material 25 side. Liquid does not leak outside.

FIG. 7 is a schematic cross section showing a fourth embodiment of the incontinence pad of the present invention. In the figure, the portions denoted by the same reference numerals as those in the first embodiment have a common configuration, and therefore, overlapping description will be omitted and differences will be mainly described.
In the figure, the incontinence pad 80 is partially different in the configuration of the opening forming means 81 from the first embodiment.

As shown in FIG. 7, a water-permeable sheet 82 that forms a water-permeable layer over almost the entire surface is disposed between the absorber 24 of the incontinence pad 80 and the back sheet 22. In this embodiment, the outer surface of the back sheet 22, for example, a part or all of the portion indicated by 22 b is adhered to the inner water-permeable sheet 82 so that it can be peeled relatively easily. The portion 81 is an opening forming means.
Specifically, the opening forming means 81 sets the adhesive peel strength of the portion 22b of the back sheet 22 to the water permeable sheet 82 so that the water permeable sheet 82 is not substantially destroyed when the portion 22b is peeled. ing. For example, you may make it perform the peeling process similar to the release paper 31 (general release paper) demonstrated in FIG. Thereby, the water-permeable sheet 82 is not damaged when the portion 22b is peeled off, and the adhesive remaining on the water-permeable sheet 82 is used together with the diaper 50 as shown in FIG. In addition, the incontinence pad 80 can function so as not to be displaced with respect to the diaper 50.
Furthermore, the portion 22b may be partitioned into a predetermined area, and a part of the outer periphery may be covered with a finger.

Therefore, since the part which peeled off this back sheet 22b exhibits the effect | action substantially the same as the opening of other embodiment, it can exhibit the effect substantially the same as other embodiment, though it is simple structure.
Further, even when the incontinence pad 80 is used alone, the portion 22b is directly bonded to the peripheral portion of the incontinence pad 80, so that urine can be used without leaking from the peripheral portion.

  The present invention is not limited to the embodiment described above. The individual configurations of the above-described embodiments can be combined with other configurations by omitting a part thereof as necessary. Moreover, each structure of each embodiment can be combined with each other. .
