Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an incontinence pad (including a "urine collecting pad") for absorbing and retaining body fluid such as urine, which is used, for example, with a disposable diaper or alone.

[0002]

2. Description of the Related Art For example, a conventional incontinence pad is constructed as follows. In general, the incontinence pad is used by a user who is worried about urine leakage and is attached to the lower body during daily life, that is, during periods when he or she is awake and acting, or during sleep at night. For this reason, the incontinence pad is applied with a liquid impermeable sheet material at a portion which becomes an outer surface when worn by the user, and an absorbent material for absorbing liquid such as urine is arranged inside thereof. ing.

FIG. 8 shows a conventional incontinence pad.
The incontinence pad 1 is mainly inserted in the inside of a diaper or an undergarment to have a long shape in the front and rear direction so that the excretory organs of the user can be covered when worn by the user. ing. A liquid impermeable back sheet 2 is used at a location that is an outer surface of the incontinence pad 1. An absorber 4 for absorbing a liquid such as urine is housed inside the back sheet 2. A surface material 5 is arranged further inside the absorber 4. This surface material 5
Is made of a material that allows liquid to pass through. The surface material 5 and the backsheet 2 are arranged so as to overlap each other at the outer peripheral portion,
Inside the surface material 5, two three-dimensional gathers 6 and 6 are provided. 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 to the outside of the incontinence pad 1. It prevents the underwear from getting dirty.

Therefore, the incontinence pad 1 has a long shape 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 one end portion thereof is disposed. 8 is located on the rear side of the body, covers the lower area of the buttocks, and the other end 9 is located on the front side of the body,
It covers the frontal excretory organs and the genital area.
Then, on the outer surface 12 of the incontinence pad 1, a displacement preventing adhesive portion 11 that is exposed when the release paper 13 is released
The adhesive portion 11 enables temporary fixing to the inner surface of a disposable diaper or underwear.

By the way, the incontinence pad 1 as described above.
For example, as a measure against incontinence or the like, as described above, the incontinence pad 1 is used as a single unit by interposing it inside a diaper or underwear, and may be used as follows. For example, in the field of nursing care, especially at night, frequently changing the diaper of a care recipient who wears a paper diaper and sleeps is a reason for the limitation of manpower and the care recipient being asleep. Is relatively difficult. For this reason, the above-mentioned easy-to-replace incontinence pad 1 is further stacked on the inside of a diaper (not shown), and after the caregiver goes to bed, the incontinence pad 1 and the paper diaper absorb the diapers and the incontinence. The pad 1 can be used without changing until the morning. Here, the incontinence pad for supplementing the absorbing power of such a diaper is sometimes called a urine absorbing pad.

[0006]

However, in the case of simultaneous use with a diaper at such a nursing care site,
There are the following problems. As described above, when the care giver wears the incontinence pad 1 inside the diaper and the cared person urinates after going to bed, if the amount and frequency of urination are large, the incontinence pad 1
It may exceed the absorption amount of and overflow.

That is, the incontinence pad 1 is formed smaller than a paper diaper, has a small amount of absorbent,
Not enough capacity to absorb. In addition, since the incontinence pad 1 has a waterproof bate 2 on the outside, the discharged urine does not penetrate into the paper diaper immediately below the incontinence pad 1 and travels through the gap between the three-dimensional gather 6 and the crotch gather 7 to There is a problem in that the urine leaks from the diaper and the urine does not reach the absorbent part of the diaper as it is, and leaks from the crotch part of the diaper to the side. Particularly, since the incontinence pad 1 can be frequently replaced in the daytime, the replacement work is reduced, so it is worth using the incontinence pad 1, but it is difficult to replace the incontinence pad 1 at night, and the leakage as described above 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,
It is an object of the present invention to provide an incontinence pad in which the excretory liquid in excess of the absorption amount is absorbed by the absorbent body of the diaper so that it does not easily leak to the side and does not leak from the diaper.

[0009]

According to the invention of claim 1, the above object has a shape elongated in one direction as a whole,
A back sheet for preventing liquid permeation, a liquid-permeable surface material arranged on the side in contact with the body, and a liquid that is arranged between the back sheet and the surface material and permeates the surface material.

BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The embodiment described below is a preferred specific example of the present invention,
Although various technically preferable limitations are given, the scope of the present invention is not limited to these forms unless otherwise specified in the description below.

FIGS. 1 and 2 show an incontinence pad according to a first embodiment of the present invention, which is an incontinence pad 20.
When it is expressed three-dimensionally, it has substantially the same form as the incontinence pad 1 described in FIG. 1 is a schematic plan view of the incontinence pad 20, and FIG. 2 is a schematic sectional view taken along the line AA of FIG. In FIG. 1, the one labeled “front” is the front side of the body when worn. Further, FIG. 1 is drawn with the outer side of the incontinence pad 20, that is, the back sheet side facing forward.

In FIGS. 1 and 2, incontinence pad 20.
Has 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 gather portions 26, 26 are upright toward the back of the paper in FIG. 1, and therefore do not appear. The back sheet 22 is an outer sheet material, and is made of a material that prevents liquid from permeating. As the 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 is impermeable to liquid, but is preferably made of a material that allows water vapor to pass therethrough to prevent stuffiness and is flexible to some extent.
This prevents the contents inside the incontinence pad 20 (solid matters such as filth, urine, blood, etc.) from leaking to the outside.

The absorber 24 is arranged and housed between the back sheet 22 and the surface material 25, and is made up of a tissue and an absorption / retention layer for absorbing and retaining liquid or the like. It is a part. Tissues are soft materials that absorb liquids, such as pulp (virgin pulp, recycled paper pulp), rayon, cotton, kenaf, bagasse, silk, hydrophilic fibers (polyolefin,
It is possible to use a single or composite sheet of polyester, acrylic, etc. 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 absorbency can be used, and examples of the material of such an absorber 24 include a polymer which is an absorbent and a polymer which is dispersed in the pulp. Pulp absorbers or polymers that form are preferred. Here, the pulp is an aggregate of cellulose fibers extracted by mechanically or chemically treating wood, for example, and a sheet-shaped one is used. Further, here, the absorbent body 24 is configured by one sheet, but it 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 fixed to the absorber 24 or the back sheet 22 by an adhesive along the longitudinal direction L (see FIG. 1), and the center surface material 28 directly contacts the user's skin. Therefore, a material suitable for this is selected in consideration of the good feeling of touch without damaging the skin more than necessary.
The center surface material 28 is also called an inner sheet or a top sheet, and is a fiber made of a material suitable for allowing a liquid to permeate therethrough and particularly a liquid component permeate therethrough. You can choose from a combination. For example, as the synthetic fiber, for example, a fiber formed of polyester or polypropylene fiber as a material 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 is permeable to liquid, while the side surface materials 29, 3
0 is made of a material that prevents the permeation of liquid. 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 (emboss, anvil, air through), airlaid, spunlace, spunbond, meltblown, needle punch, stitch bond, Further, SM non-woven fabric (spun bond / melt blown laminate), SMS non-woven fabric (spun bond / melt blown / spun bond laminate) made by combining spun bond and melt blown non-woven fabric can be adopted. Thermal bond, spun bond, and spun lace are particularly preferable as the material of 28. Further, as the material of the side surface materials 29 and 30, for example, a polyolefin-based nonwoven fabric or a polyester-based nonwoven fabric and a thin plastic film are used. Which combined, a combination of polyester nonwoven fabric such as polyethylene film or the like, SM nonwoven, SMS nonwoven fabric or the like can be employed.

The left and right three-dimensional gathers 26, 26 are formed by arranging an elastic body 55 at least in the longitudinal central portions of the side surface materials 29, 30, respectively. The three-dimensional gather portion 26 is a side surface material 30 in the illustrated example.
Is formed by arranging an elastic body at least in the central portion in the longitudinal direction L. In order to form the three-dimensional gather portion 26, the linear elastic body 55 is housed along the longitudinal direction L in at least the central portion of the side surface material 29 or the side surface material 30. Due to the elastic contraction capability of the elastic body 55, the three-dimensional gather portion 26 stands up at least at the center of the side surface materials 29 and 30, as shown by the arrow in FIG. By forming the three-dimensional gather portion 26, the excrement or liquid component of the user is closely adhered to the user's body and prevented so as not to leak outside along the lateral direction T of the incontinence pad 20. The crotch gather portion 27 cooperates with the three-dimensional gather portion 26 to pull both ends in the lateral direction corresponding to the crotch of the incontinence pad 20 by the elastic force of the elastic body 55, thereby enhancing the fit to the user's crotch. Prevents user's excrement or liquid components from leaking from the crotch area.

Further, 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 house 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 provided with respect to the side surface materials 29 and 30, for example,
It is fixed integrally using heat seal. Elastic body 5
5 is made of, for example, a linear elastic material, specifically, rubber or a film-shaped elastomer, and is accommodated in the bag-shaped portions of the side surface materials 29 and 30.
The contact portions of other members such as the back sheet and the side surface material are basically adhered by hot melt, for example, but the illustration is omitted for simplification of the drawing.

As shown in FIG. 1, the incontinence pad 2
In the vicinity of both ends in the longitudinal direction of 0, release preventing release papers 31 and 32 are attached on the back sheet 22. When the release papers 31 and 32 are peeled off, the temporary fixing portions using the adhesive are exposed below, and the temporary fixing portions are temporarily fixed to the inner surface of the underwear of the user, 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 longitudinal direction L of the incontinence pad 20, that is, in the illustrated case, at a position slightly rearward from the center. It is provided. By operating the opening forming means 40 as described later, the opening 41 is provided so as to be provided in the back sheet 22 located therebelow. The opening forming means 40 will be described later in more detail.

FIG. 3 is a schematic cross-sectional view showing how the incontinence pad 20 is used by being stacked on a diaper. In this case, for example, a paper diaper 50 is used as the diaper. The disposable diaper 50 is larger than the incontinence pad 20, but the incontinence pad 2
The same configuration as that of 0 can be used. That is, the paper diaper 50 has a back sheet 52, an absorber 53, a surface material 55, left and right three-dimensional gather portions 56, 56, and left and right crotch gather portions 57, 57. And incontinence pad 2
No. 0 exposes the opening 41 by the above-described opening forming means 40, and is placed so that the opening 41 faces the center surface material 58 of the diaper 50 as shown in the drawing. In this case, the deviation prevention release papers 31 and 32 of the incontinence pad 20 described in FIG. 1 may be peeled off and fixed to the surface material 28 of the diaper 50.

Thus, 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 passed through the opening 41 to the diaper 5.
It is adapted to be absorbed by the absorber 53 of zero. This point will be described later in detail.

FIG. 4 is an enlarged perspective view for explaining the structure of the opening forming means 40, and the opening forming means 40 will be described in detail with reference to FIGS. 4 and 2. The opening forming means 40 is for forming the opening 41 on the outer surface of the back sheet 22, and is closed when the incontinence pad 20 is used alone. Then, as described with reference to FIG. 3, when the incontinence pad 20 is used by being stacked on the diaper 50, the opening 41 is exposed.

Specifically, as shown in FIG. 4, the opening 41
Corresponding to, the breaking guide portion 44 is formed so as to partition the opening 41 of the back sheet 22. Fracture guide 4
4 is a location where stress concentrates when the opening forming means 40 tries to form the opening 41. That is, the fracture guide portion 44 is a means for easily cutting off a part of the back sheet 22 to form the opening 41, and in the present embodiment, holes are continuously formed along the opening 41.
That is, the breaking guide portion 44 is provided, for example, 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 does not penetrate the back sheet and has a bottom of the hole like perforations. Therefore, this hole is
It may be shaped like a stretch of groove when continuous along. That is, this hole is formed in the backsheet and has a form like a hole or a groove that does not penetrate the backsheet. Accordingly, when the incontinence pad 20 is used alone and the opening 41 is not formed,
Liquid is prevented from leaking out through this hole.

A water-permeable cover member 43 is provided between the back sheet 22 and the absorbent body 24 at a position located on the back side of the opening 41.
It is glued and placed on. The water-permeable cover member allows the liquid to permeate therethrough, but prevents the absorbent polymer, for example, from coming out from the absorbent body 24 side, and may have such a function. As long as it has any form, it may be provided not only around the opening 41 but also on the entire surface between the back sheet 22 and the absorber 24. In this embodiment, the water permeable sheet 43 is used as the water permeable cover member. As the water permeable sheet 43, the same material as the center surface material can be used.

Further, the opening forming means 40 has a peeling sheet 42 attached from the outside of the back sheet 22 so as to cover the opening 41. The release sheet 42 itself does not have a special configuration, and a widely used release paper or the like can be used except that it is made of a material that does not allow moisture to permeate. The peeling sheet 42 is, for example, pulled in the direction of arrow B in FIG. 4 and peeled off, whereby a part of the back sheet 22 thereunder is cut off along the breaking guide portion 44, and the cutout portion 22a is cut off. The opening 41 is formed by being removed while being attached to the release sheet 42 side. That is, the part corresponding to the cutout portion 22 a of the back sheet 22 is firmly adhered to the peeling sheet 42 in advance.

Further, an adhesive portion 45 adhered to the water-permeable sheet 43 is provided on the inner surface side of the region of the edge portion on the peeling direction (arrow B direction) side of the peripheral portion of the opening 41 of the back sheet 22. As a result, when the peeling sheet 42 is peeled as shown in FIG. 4, the adhesive portion 45 of the back sheet 22 is separated from the water permeable sheet 43 when the cutout portion 22a is cut off.
Since it is fixed to the side, it is prevented from being pulled by the peeling sheet 42 and being torn, and the peripheral edge of the opening 41 is torn.

Further, in order to ensure such an effect, the back sheet 22 is preferably made of a plastic film for forming the back sheet 22 in the longitudinal direction of the incontinence pad 20, that is, in the peeling direction B in FIG. It is made of material stretched in the same direction. As a result, the back sheet 22 is directionally easy to tear in the peeling direction B, and is prevented from being pulled by the peeling sheet 42 and being torn. In addition, back sheet 2
Even when 2 is formed of a biaxially stretched film, the same effect can be obtained by using a material in which the direction coinciding with the peeling direction B is more strongly stretched.

The present 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. Since it is provided, the underwear can be used so as not to be contaminated by urinary incontinence, etc., or can be used as it is in combination with the paper diaper 50 during the daytime to reduce the work of diaper replacement. And, in particular,
In the field of nursing care and the like, as described with reference to FIG. 3, the incontinence pad 20 is further stacked on the inside of the disposable diaper 50, so that the absorbed amount of the disposable diaper 50 becomes incontinent after the care recipient goes to bed. Since the absorption amount of the pad 20 is added, it is not necessary to replace the diaper 50 until morning, the care recipient's sleep is not hindered, and the caregiver's burden can be reduced.

Specifically, when a user such as a cared person wears the diaper 50 at the time of sleeping, not only the diaper 50 but also the incontinence pad 20 is overlaid inside the diaper 50 as shown in FIG. Be installed. In this case, by pulling the peeling sheet 42 described in FIG. 4 in the direction of the arrow B, the opening 4 is formed on the outer surface of the back sheet 22 of the incontinence pad 20.
1 is exposed, and the opening 41 is arranged so as to face the surface material 55 of the diaper 50.

By using the one placed on the diaper 50 with the opening 41 of the incontinence pad 20 opened before going to bed, the absorption amount exceeding the excretion amount of urine until the morning is secured,
The burden of changing diapers at night can be reduced.

As described above, when a large amount of urine is discharged during nighttime use and exceeds the absorption amount of the incontinence pad 20, or when the urine discharge speed is extremely fast, the discharged urine is In FIG. 3, incontinence pad 2
After being absorbed by the absorber 24 through the surface material 25 of 0,
As for urine that is not absorbed, a large amount of urine does not accumulate in the portion above the surface material 25, and a large amount of urine is discharged.
1 through the surface material 55 of the diaper 50, the absorber 5
Sucked into 3.

As a result, the surface material 25 of the incontinence pad 20 is obtained.
The urine that has temporarily stayed in the upper part flows to the side, and the three-dimensional gathers 26, 26 and the crotch gathers 27, 27 are gathered.
It is possible to effectively prevent the situation of leaking from around the crotch of the user beyond the diaper 50 beyond the diaper 50.
Alternatively, the urine that has temporarily accumulated above the surface material 25 of the incontinence pad 20 will spread to the back of the user who is in a sleeping position while sleeping. In the present embodiment, as shown in FIG.
In regard to the longitudinal direction L of the incontinence pad 20, the opening forming means 40 is provided in the central region, that is, in the illustrated case, at a position slightly rearward of the central region. Since the opening 41 is formed in advance in the opening forming means 40 as described above, the opening 41 is prepared corresponding to the position where the urine is discharged, and the urine is incontinence before turning to the back surface. The diapers 50 are absorbed through the openings 41 through the absorber 24 of the pad 20.

Further, the incontinence pad 20 of this embodiment is
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, the back sheet 22 has no opening and is sealed.

As shown in FIG. 7, the incontinence pad 8
A water permeable sheet 82 that forms a water permeable layer is disposed over almost the entire surface between the absorber 24 of 0 and the back sheet 22. And in this embodiment, the back sheet 2
2 A part or all of the outer surface, for example, a part indicated by 22b is adhered to the water permeable sheet 82 inside so that it can be peeled off relatively easily, so that this part 81 serves as an opening forming means. There is. Specifically, the opening forming means 81
The portion 22b of the back sheet 22 is a water permeable sheet 82.
On the other hand, the adhesive peel strength is set so that the water-permeable sheet 82 is not substantially destroyed when the portion 22b is peeled off. For example, the release paper 31 (general release paper) described with reference to FIG. 1 is provided on the surface of the portion 22b that is bonded to the water-permeable sheet 82.
You may make it perform the peeling process similar to. As a result, 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 when the incontinence pad 80 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. Further, the portion 22b may be divided into a predetermined area, and a part of the outer periphery thereof may be used as a finger.

Therefore, since the portion from which the back sheet 22b is peeled off exhibits substantially the same action as the opening of the other embodiments, it is possible to exert substantially the same action and effect as those of the other embodiments while having a simple structure. it can. Even when the incontinence pad 80 is used alone, since the portion 22b is directly adhered to the peripheral portion of the incontinence pad 80, it can be used without leaking urine from the peripheral portion.
