The contact ratio between the malodor components and activated carbon is therefore heightened to sufficiently exhibit the deodorizing effect of the activated carbon, thus attaining positive deodorization.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to sanitary napkins, vaginal discharge sheets, light incontinence sheets, incontinence disposable pants, disposable paper diapers, and other body fluid-absorbing articles, which are generated from excrement and body fluids. The present invention relates to a bodily fluid absorbent article having an odor deodorizing function.

[0002]

2. Description of the Related Art Conventionally, in order to deodorize unpleasant odors generated from excretions, body fluids and the like, some body fluid absorbent articles use a deodorant. In particular, sanitary napkins generate various odors during menstruation not only from blood but also from uterine tissues, vaginal secretions, sweat, etc. The types of components are diverse. The quality of the odor also changes during the very early, middle, and late stages of menstruation, and there are individual differences in the components of this odor. Therefore, a deodorant capable of comprehensively deodorizing such a variety of malodorous components is desired. Also, during menstruation, because the human body is also delicate, this deodorant not only has excellent deodorant function,
It is preferably a hygienic and human-safe substance.

[0003] In view of these circumstances, it has been widely known to use activated carbon having high safety for the human body as a deodorant. This activated carbon has a large surface area and physically adsorbs malodorous components and can effectively deodorize it.

A conventional sanitary napkin using this activated carbon will be described with reference to FIGS. 5 and 6. (1) is a water-permeable topsheet, which is provided on the back side of the topsheet (1). A leaky back sheet (2) is provided. In addition, surface sheet (1)
Pulp or superabsorbent polymer between the back sheet (2)
(Not shown) and the like are disposed. In the first conventional example shown in FIG. 5, an activated carbon compound sheet (5) formed by mixing activated carbon (4) with an absorbent material such as pulp on the back sheet (2) side of the absorbent layer (3). Has been arranged.
By contacting the activated carbon (4) of the activated carbon blended sheet (5) with a malodorous component, an attempt is made to deodorize malodors generated from body fluids.

[0005]

However, the bodily fluid discharged from the human body passes through the topsheet (1) and is absorbed by the absorbent layer (3) above the activated carbon (4). (3) It is locked in. Therefore, it hardly reaches the activated carbon blended sheet (5) side after passing through the absorbent layer (3), and the malodor component of the body fluid and the activated carbon (4) are not brought into good contact with each other, and the deodorizing effect is not obtained. I couldn't show it enough.

In the second conventional example shown in FIG. 6, two absorbing layers thinner than the absorbing layer (3) of the first embodiment are provided between the top sheet (1) and the back sheet (2). (3) is arranged, and an activated carbon blended sheet (5) is arranged between the two absorbent layers (3). Thus, the activated carbon blended sheet (5) is
By placing it in the middle of (3), the contact rate with the body fluid is to be increased, but half or more than half of the body fluid has a surface sheet (1) or an absorbent layer (above the activated carbon (4)) on the upper layer side. Activated carbon (4) is absorbed in 3) and remains inside these.
Could not exhibit the deodorizing effect sufficiently.

[0007] Further, when the body fluid in the absorbing layer (3) is vaporized, a malodorous component is generated from the absorbing layer (3), and most of the malodorous component rises to the surface sheet (1) side. Since it diffused and hardly contacted the activated carbon-containing sheet (5), good deodorization could not be performed, and an unpleasant odor leaked to the outside, giving anxiety to the wearer.

SUMMARY OF THE INVENTION The present invention is to solve the above-mentioned problems, and arranges a deodorant made of activated carbon at a position close to a surface sheet of an absorbent layer so as to come in contact with an odor generated from excrement and body fluid. By making it easier to carry out, it is intended to effectively deodorize.

[0009]

According to the present invention, in order to solve the above-mentioned problems, a body fluid absorbing layer is disposed between a back sheet and a water-permeable top sheet. A deodorant made of activated carbon is arranged on the top sheet side.

The activated carbon may be arranged on the surface sheet side of the absorbent layer between the surface sheet and the absorbent layer.

[0011] A body fluid absorbing sheet may be provided between the activated carbon and the topsheet.

The activated carbon may be formed into a sheet having a uniform area with the absorption layer.

Further, the activated carbon may be formed in a sheet shape with an area smaller than that of the absorption layer.

Further, the activated carbon may be formed in a sheet shape by a sheet forming member.

The back sheet may be a water-impermeable leak-proof sheet.

Further, the back sheet may have air permeability.

[0017]

Since the present invention has been formed as described above,
Body fluids such as menstrual blood, vaginal discharge, urine, and sweat, which are discharged from the user of the body fluid absorbent article, pass through the water-permeable top sheet, flow toward the absorbent layer, and are absorbed in the absorbent layer. You. During this absorption process, the body fluid comes into contact with the activated carbon disposed on the surface sheet side of the absorption layer. This activated carbon deodorizes by physically adsorbing the offensive odor component, so that it can effectively deodorize irrespective of the type and quality of the odor. Then, the body fluid is confined in the absorption layer after the malodorous component is successfully removed by the activated carbon.

Further, as the time elapses, the body fluid absorbed by the absorbing layer evaporates, and the body fluid oxidizes and decomposes, thereby generating an offensive odor. Then, this malodorous component rises to the top sheet side together with the water vapor and tries to diffuse to the outside. However, in the process of this rise, the malodorous component comes into contact with the activated carbon disposed on the top sheet side, so that it is well deodorized, and only water vapor diffuses to the outside. As described above, the unpleasant odor does not leak to the outside when the absorbent article is mounted due to the excellent deodorizing effect of the activated carbon, thereby providing the wearer with a sense of security and comfortable mounting.

If the activated carbon is disposed on the surface sheet side, the activated carbon may be mixed in the pulp on the surface sheet side of the absorbent layer and disposed in the absorbent layer, or may be disposed separately from the absorbent layer. Activated carbon may be prepared, and the activated carbon may be arranged between the absorbent layer and the topsheet. In any case, since the activated carbon is arranged on the side close to the topsheet, the contact rate with the malodorous component of the body fluid increases, and effective deodorization becomes possible.

Further, in the present invention, the activated carbon is arranged on the side of the absorbent layer close to the topsheet, so that the black of the activated carbon may be seen through the topsheet depending on the type and thickness of the material of the topsheet. is there. Then, the user who sees the black color may feel dirty and may avoid using the absorbent article. Therefore, if a body fluid absorbing sheet is disposed between the activated carbon and the topsheet, the absorption sheet and the topsheet will cover the activated carbon, making the black color less visible. Further, since the body fluid and the malodorous component hardly remain on the body fluid-absorbing absorbent sheet and can reach the activated carbon, the deodorizing effect of the activated carbon is not impaired.

When the activated carbon is used in the form of granules, powders, or the like as it is, it is possible to allow gas and liquid to freely pass therethrough, and the irritation to the skin is reduced. However, since the granular or powdered activated carbon is light and easily scattered, the workability at the time of production may be deteriorated and uniform dispersion in the absorbent layer may be difficult. In addition, due to the stimulus during use of the absorbent article, activated carbon spills from the gap between the top sheet and the back sheet, or moves on the surface of the absorbent layer and becomes unevenly dispersed, resulting in a feeling of use and deodorant function. It may be reduced. Therefore, activated carbon,
If the activated carbon is formed into a sheet so as not to be dispersed, the stability of the activated carbon can be improved, the handling at the time of production can be facilitated, and the activated carbon can be uniformly dispersed in the absorption layer.

To make the activated carbon into a sheet,
A sheet forming member such as a paper-like or cotton-like pulp or a nonwoven fabric may be used. For example, a sheet is formed by applying or bonding activated carbon to the surface of paper pulp. Also, if activated carbon is dispersed in the fibers of floc pulp to form a sheet,
Since the fibers are entangled with the activated carbon, the stability of the activated carbon is further improved. There is also a method of forming a nonwoven fabric containing activated carbon by mixing nonwoven fabric fibers and activated carbon in the process of forming the nonwoven fabric. In any case, the activated carbon sheet is easier to handle, and can be uniformly dispersed in the absorbent article, and can be effectively deodorized as compared with the activated carbon powder or granules.

Further, when the activated carbon is formed into a sheet shape as described above, if the activated carbon is formed in a uniform area with the absorbent layer, the cost is increased. The odor components are reliably absorbed by the entire surface of the article and do not leak to the outside. In addition, if the sheet-shaped activated carbon is formed with an area smaller than the absorption layer, the cover power at the time of diffusion is reduced, but by arranging the activated carbon at a position where body fluids are easily concentrated, effective deodorization becomes possible. . Further, a product can be formed at low cost.

In the case of a body fluid-absorbing article for absorbing a small amount of body fluid, such as a vaginal discharge sheet or a light incontinence sheet, a breathable material such as a nonwoven fabric may be used as the back sheet. In this case, economical production becomes possible, and at the same time, stuffiness and stiffness are prevented, and a comfortable feeling of use is obtained. In the case of a body fluid absorbent article for absorbing a large amount of body fluid, such as a sanitary napkin, incontinence disposable pants for absorbing a large amount of urine, a disposable disposable diaper, etc., a non-water permeable leakproof as a back sheet. By arranging the seat, it is possible to satisfactorily prevent leakage of bodily fluids. still,
It is of course possible to use a water-impermeable leakproof sheet also for the above-mentioned veneer sheet and a back sheet such as a small amount of disposable disposable pants.

[0025]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention implemented with a sanitary napkin will now be described with reference to the drawings.
By being formed of a polyethylene film provided with a large number of flow holes, excellent air permeability and water permeability are obtained. Further, a backsheet (11) having excellent leakproofness is provided by arranging a polyethylene film or the like having no flow holes on the backside of the topsheet (10). The outer surface of the back sheet (11) is coated with hot melt to form a fastening portion (13) for shorts, and the surface is covered with release paper (not shown).

The top sheet (10) and the back sheet (1)
An absorbent layer (12) made of pulp, a suitable superabsorbent polymer (not shown), or the like is disposed between the absorbent layer (1). And
Between the absorbent layer (12) and the topsheet (10), and the absorbent layer
(12) and the back sheet (11), between the absorbent sheet (1)
4) is arranged. The absorbent sheet (14) has an area capable of covering the entire upper surface or the entire lower surface of the absorbent layer (12), and is formed of a humor-absorbing material such as pulp or nonwoven fabric.

Further, the absorbent sheet on the side of the top sheet (10)
Between the (14) and the absorbent layer (12), granular or powdered activated carbon (15) is arranged as a deodorant. In this example, 0.02 g or more of activated carbon (15) was blended into one sanitary napkin. If the blending amount of the activated carbon (15) is at least 0.02 g or more, it can absorb the malodorous component of the body fluid discharged on average.

In consideration of the case where the body fluid is used at a time when the amount of the body fluid is large, the activated carbon (15)
Is preferably compounded in an amount of 0.1 g or more. However, activated carbon (15)
If the blending amount is too large, the sanitary napkin will be stiff,
As there is a possibility that the touch and the fit to the skin may decrease,
It is preferable to mix an appropriate amount. In addition, activated carbon (1
5) is arranged at the center of the absorbing layer (12) as shown in FIG. 1, and its distribution area is less than half the surface area of the absorbing layer (12).

As described above, the contact ratio with the body fluid is increased by arranging the activated carbon (15) at the center of the absorbent layer (12) where the body fluid is most concentrated. In addition, by arranging the activated carbon (15) at a position close to the topsheet (10), the activated carbon (15) can be easily and efficiently contacted with malodorous components generated from body fluids and the like, thereby enabling efficient deodorization. .

The activated carbon (15) has a black color. However, since the activated carbon (15) is covered with the absorbent sheet (14) and the topsheet (10), the black color is hardly transparent to the outside and is visually preferable. Product. In addition, an absorbent sheet (14) or a topsheet (10) arranged in a layer above the activated carbon (15)
In addition, the body fluid permeates or adheres to the body fluid, so that the body fluid remains in the body fluid. If the amount of the body fluid is large, the contact ratio with the activated carbon (15) decreases, and the deodorizing effect decreases. The residual amount of the bodily fluid varies depending on the type and thickness of the material of the absorbent sheet (14), the fiber density, the number and size of the circulation ports of the topsheet (10), and the like. Therefore, if the absorbent sheet (14) and the topsheet (10) in the upper layer portion than the activated carbon (15) are formed so as to reduce the residual amount of the body fluid, the activated carbon (15)
This increases the rate of contact with, and enables effective deodorization.

In order to satisfy the above conditions, for example, 5.0 g of high-viscosity simulated menstrual blood is applied to the napkin body of the present invention.
When injected into (16), the topsheet (10) and the topsheet (10) are arranged so that the amount of menstrual blood remaining on the topsheet (10) and the absorption sheet (14) above the activated carbon (15) is 2.5 g or less. If an absorbent sheet (14) is formed, more than 2.5 g of menstrual blood
Absorbed on the lower layer side including (15). By forming in this manner, during actual use, menstrual blood containing impurities such as intrauterine tissue hardly remains in the upper layer than the activated carbon (15), and is in good contact with the activated carbon (15). As a result, it is possible to effectively deodorize the offensive odor component.

Further, in order to further improve the deodorizing effect, in 5.0 g of simulated menstrual blood with high viscosity, residual menstrual blood remains on the surface sheet (10) and the absorption sheet (14) in the upper layer than the activated carbon (15). 1.5g
It is preferable that the lower layer containing the activated carbon (15) absorbs menstrual blood of 3.5 g or more. More preferably, the residual amount of menstrual blood in the upper layer is within 5.0 g
It is preferable that the amount is 0.5 g or less, and the amount of absorption in the lower layer portion is 4.5 g or more. If formed in this way, the actual menstrual blood hardly remains on the upper layer side than the activated carbon (15), and comes into contact with the activated carbon (15) without fail, so that the malodorous component is well deodorized. Becomes

In addition, when the sanitary napkin of the present embodiment is used using sheep's blood, it is preferable to use the upper layer, that is, the topsheet (10) and the absorbent sheet (14), above the activated carbon (15). Record the residual amount of blood. In addition, this sheep blood has a low viscosity state in which the fiber component in the blood has been removed in order to prevent coagulation. Then, when 5.0 g of this sheep blood is injected into the napkin body (16), the residual amount on the surface sheet (10) and the absorbent sheet (14) in the upper layer than the activated carbon (15) is reduced.
If the topsheet (10) and the absorbent sheet (14) are formed so as to be 2.0 g or less in 5.0 g, 3.0 g or more of the blood in 5.0 g is absorbed into the lower layer side containing the activated carbon (15). It will be.

Preferably, the topsheet (10) and the absorbent sheet (14) are formed such that the amount of sheep blood remaining in the upper layer of the activated carbon (15) is 1.5 g or less in 5.0 g. For example, the absorption in the lower layer containing activated carbon (15) is 3.
5g or more. More preferably, the residual amount in the upper layer is 5.
The content is preferably 0.5 g or less in 0 g, and the absorption in the lower layer containing the activated carbon (15) is 4.5 g or more in 5.0 g. When formed in this manner, the actual menstrual blood comes into good contact with the activated carbon (15), and a sanitary napkin having an excellent deodorizing effect can be obtained.

In the sanitary napkin as described above, the body fluid discharged from the wearer is applied to the surface sheet of the napkin body (16).
Fall to (10). This body fluid includes not only blood but also intrauterine tissues, vaginal secretions, sweat, and the like, from which various malodorous components are generated. Then, this bodily fluid, together with the offensive odor component, is passed through the through-holes of the topsheet (10) to the absorbent sheet.
It flows to the (14) side, passes through this absorbent sheet (14),
It flows to the absorption layer (12) side. As described above, since the amount of the body fluid remaining on the topsheet (10) and the absorption sheet (14) is small, most of the body fluid flows to the absorption layer (12) side.

During this flow process, the body fluid comes into contact with the activated carbon (15) arranged on the surface sheet (10) side of the absorbent layer (12). By this contact, the malodorous component in the body fluid is converted into activated carbon (1
It is physically adsorbed to 5) and effectively deodorized. In the napkin body (16) of this embodiment, activated carbon was used.
As shown in FIG. 1, (15) is arranged at the center where the bodily fluid tends to concentrate, so that efficient deodorization is possible. Then, the body fluid having been subjected to the good deodorization is absorbed by the pulp of the absorbent layer (12) or gelled by the superabsorbent polymer, and is confined inside the absorbent layer (12).

Further, as time passes, the body fluid in the absorbent layer (12) oxidizes and decomposes, generating a new odor. Furthermore, since the moisture in the body fluid evaporates due to the body temperature of the wearer, the water vapor containing the malodorous component rises in the direction of the topsheet (10). Then, in the conventional product, there is a problem that the malodorous component leaks outside. However, in the present invention, activated carbon (1) is provided on the surface sheet (10) side of the absorbent layer (12).
5) is located, so that activated carbon is
(15) intervenes.

[0038] By contact with the activated carbon (15), malodorous components are surely deodorized, and only water vapor is emitted to the outside. In addition, since the activated carbon (15) is disposed on the surface sheet (11) side, the odor generated on the skin side of the wearer due to stuffiness and the like is easily adsorbed by the activated carbon (15), and good deodorization is possible. Become. Therefore, the wearer of the sanitary napkin is given a sense of security and a comfortable wearing feeling.

When the powdered or granular activated carbon (15) is used as it is, it is light and easily scattered, so that it is troublesome to handle. Therefore, in the method of arranging the powdery or granular activated carbon (15) on the surface of the absorbent layer (12) as in the first embodiment, it takes time to manufacture or
(12) There is a fear that problems such as the inability to uniformly disperse the toner or the formation of the sanitary napkin by being soiled may occur. Also,
Activated carbon (15) is absorbed by the stimulus during transportation and wearing of the product
There is a possibility that the surface of (12) is unevenly dispersed by moving on the surface, thereby deteriorating the deodorizing effect and the touch.

In order to solve this problem, when forming the absorbent layer (12), activated carbon was added to the pulp of the absorbent layer (12).
If (15) is mixed, the fibers of the pulp are entangled with the activated carbon (15) and retained, so that the skew is prevented and the activated carbon (15)
Stability is improved. Also in this case, activated carbon (15)
By arranging on the side close to the top sheet (10) of the pulp, it is possible to reliably deodorize the malodorous component.

In order to make the activated carbon (15) easier to handle and improve the stability in the absorption layer (12), the activated carbon in the form of powdered or granular activated carbon as shown in FIG.
(15) is blended in the inside of the cotton-like pulp. Then, the entire upper surface of the cotton-like pulp is covered with a body fluid-absorbing upper sheet (18), and a body fluid-absorbing lower sheet (19) is also arranged on the entire lower surface, so that the activated carbon compound sheet (17) is formed. Is formed. In the present embodiment, the activated carbon (15) is uniformly dispersed on the lower sheet (19) side of the cotton-like pulp.

The activated carbon-containing sheet (17) can be used as an auxiliary absorber by thickening or mixing a water-absorbing polymer or the like into the inside, thereby giving the sanitary napkin a deodorizing function. In addition, it improves body fluid absorption. And this activated carbon compound sheet (1
As shown in FIG. 3, the surface sheet (1) of the absorbent layer (12) was
0) side. According to this method, it is troublesome and costly to form the activated carbon-containing sheet (17), but activated carbon is required.
(15) is easy to handle, so that the workability during manufacturing is improved, and at the time of mounting, uniform dispersion is maintained, and the deodorizing effect and the feeling of use are improved. Also, the black color of the activated carbon (15) becomes less noticeable with the pulp fibers and the upper sheet (18),
A product with a more favorable appearance is obtained.

In this example, the activated carbon-containing sheet (1
7) is formed in an area that is one third or less of the area of the absorption layer (12), and is disposed at the center where the bodily fluid is easily concentrated. In addition, the surface sheet (10) of the activated carbon compound sheet (17)
On the side, an absorbent sheet (14) is arranged. Also, in the sanitary napkin of this embodiment, as in the first embodiment, activated carbon is used.
The remaining amount of bodily fluids on the upper layer members (15), that is, the top sheet (18) and the cotton pulp of the topsheet (10) and the absorbent sheet (14), and the top sheet (18) of the activated carbon blended sheet (17) is reduced. Formed. By forming in this way, activated carbon
(15) The deodorizing function can be effectively exhibited.

In this embodiment, as shown in FIG. 4, the activated carbon (15) is arranged on the lower sheet (19) side of the cotton-like pulp in the activated carbon compound sheet (17). It may be dispersed throughout the cotton-like pulp or may be arranged on the upper sheet (18) side. In any case, as shown in FIG. 3, since this activated carbon-containing sheet (17) is arranged between the absorbent layer (12) and the topsheet (10), the contact ratio with the malodorous component is high and excellent. It has a deodorizing effect.

When the sanitary napkin of this embodiment is used, the malodorous components generated from the body fluid and the like pass through the surface sheet (10) and the absorbent sheet (14) together with the body fluid and reach the activated carbon compound sheet (17). I do. Then, the bodily fluid is absorbed by the activated carbon-containing sheet (17), so that the malodorous component comes into contact with the activated carbon (15), so that good odor is eliminated. Also, if a large amount of bodily fluid is discharged,
In the activated carbon blended sheet (17), the odor components are removed and satisfactorily removed while flowing toward the absorption layer (12).

Further, due to oxidation and decay of the body fluid in the absorption layer (12) and vaporization of moisture, water vapor containing a malodorous component rises toward the top sheet (10). This malodorous component is well deodorized by the activated carbon (15) arranged in the ascending route similarly to the first embodiment, so that unpleasant odor is not released to the outside and comfortable use is maintained. .

In the first and second embodiments, the absorption layer
The activated carbon (15) is arranged in the absorbent layer (12) with an area of less than half or less than one third of the surface area of (12). In another different embodiment, activated carbon is applied to the entire surface of the absorbent layer (12).
(15) may be dispersed, or an activated carbon blended sheet (17) may be formed in the same area as the absorption layer (12) and disposed on the absorption layer (12). When formed in this way, although the manufacturing cost of the sanitary napkin is increased, since the malodorous component can be reliably captured on the entire surface of the napkin body (16), more effective deodorization can be achieved.

In the above embodiment, the activated carbon (15) is blended in the sanitary napkin. However, it can be used for a vaginal discharge sheet, disposable pants for incontinent persons, disposable disposable diapers, and other absorbent articles. It is. Also in this case, it is preferable to mix the activated carbon (15) in an appropriate amount and distribution area according to the size of the absorbent article, the amount of excrement, and the amount of body fluid. In all products, activated carbon (15) is coated with an absorbent layer (1).
By arranging it on the surface sheet (10) side of 2), various odors generated from excretions and body fluids are surely brought into contact with the activated carbon (15), thereby exhibiting an excellent deodorizing effect.

[0049]

As described above, the present invention is constructed as described above, so that malodorous components generated from body fluids and excretions can be effectively deodorized by the physical adsorption power of activated carbon. And by arranging activated carbon on the side near the top sheet of the absorbent article, the contact ratio between the malodorous component and the activated carbon is increased, the deodorizing effect of the activated carbon is sufficiently exhibited, and reliable deodorization is possible. . Therefore, an unpleasant odor is not leaked to the outside when the absorbent article is worn, and the wearer is given a sense of security and a comfortable feeling of use.
