Description

  The present invention relates to a disposable paper diaper comprising a liquid-permeable top sheet, a liquid-impermeable back sheet, and an absorbent body interposed between the two sheets, and three-dimensional gathers formed on both sides of the front side. It is. More specifically, the present invention relates to a disposable paper diaper that can inform the wearer's excretion.

This type of disposable paper diaper includes: a water-soluble resin layer containing a volatile substance having a fragrant fragrance and a water-soluble resin containing no volatile substance provided on one side of the water-soluble resin layer. "With a fragrant spreading layer having a layer" (for example, refer to Patent Document 1) and "a odorant that generates odor when touched by moisture so as to be in contact with moisture" (for example, Patent Document 2). In these conventional disposable paper diapers, when the wearer excretes, aroma and odor are generated, so that a guardian / guardian can know the excretion of the wearer.
However, although these conventional disposable diapers have a function of notifying excretion, they do not have a function of notifying whether it is urination or defecation. Therefore, since disposable disposable diapers are replaced without knowing whether they are urinating or defecation, for example, loose stool may flow out, causing clothes to be damaged by a supervisor or the like. Moreover, since the disposable paper diaper after defecation has a poor absorption performance and easily leaks, it is necessary to replace the disposable paper diaper as soon as possible particularly in the case of defecation. Furthermore, in the case of defecation, there is a problem of stool rash, so it is necessary to replace disposable disposable diapers as soon as possible.

  Next, an embodiment of the present invention will be described. In the following, a case where the disposable paper diaper is a “fastening tape type disposable paper diaper” will be described as an example, but the present invention is also applicable to a case where the disposable paper diaper is a “pants-type disposable paper diaper”. is there.

[Disposable disposable diaper shape, etc.]
As shown in FIGS. 1 and 2, the disposable paper diaper 10 according to the present embodiment is provided with a liquid-permeable front side sheet 11, a liquid-impermeable back side sheet 12, and interposed between both sheets 11 and 12. The main body is provided with the absorber 31. The surface side sheet 11 is mainly formed by laminating a top sheet 1, a second sheet 4, and a surface portion 32 </ b> A of a covering sheet 32 described later in this order. The back side sheet 12 is mainly formed by laminating the back side 32B of the covering sheet 32 and the back sheet 2 in this order. The back sheet 2 may be composed of one (single layer) sheet, or may be composed of two, three, four, or more sheets. As a form comprised by two sheets, the form by which the bodily fluid impermeable waterproof sheet and the bodily fluid permeable exterior sheet were laminated | stacked in this order can be illustrated, for example. At this time, for example, the waterproof sheet can be disposed only in the area where the absorber 31 exists.

  On the other hand, in this embodiment, the absorbent body 3 is configured by covering the absorbent body 31 with the covering sheet 32. The shape of the absorbent body 31 is maintained by the covering sheet 32. For example, as shown in FIG. 1, the absorbent element 3 can have a planar hourglass shape with a narrow central portion in the front-rear direction.

  The top sheet 1 and the back sheet 2 have the same shape as the planar outer shape of the paper diaper 10, and the front and rear end portions and both side portions extend forward and rearward or laterally from the front and rear end edges or both side edges of the absorbent element 3. Yes. The lateral extension of the top sheet 1 and the back sheet 2 is particularly long at the front and rear ends. For example, a fastening material such as a fastening tape (not shown) can be attached to the long extending portion (hereinafter also simply referred to as “extending portion”).

  Further, the top sheet 1 and the back sheet 2 are joined at the extending portion. The bonding method is not particularly limited. For example, hot melt bonding, ultrasonic sealing, heat sealing (thermal fusion), heat pressing (thermocompression bonding), or a combination thereof can be used.

  In the paper diaper 10 according to the present embodiment, the microcapsules 5A, 5B (see FIGS. 3 to 6), in which the fragrance component is a core material and the fragrance component flows out when contacted with excrement such as urine and feces, are provided in the urine receiving portion. It is given to (the part where the paper diaper 10 is urinated) and the toilet part (the part where the paper diaper 10 is defecate). And the fragrance | flavor component of a urine receiving part and the fragrance | flavor component of a toilet part are set to be different. Therefore, if the urine is urinated, the fragrance component of the urine receiving part will evaporate, and if it is defecation, the fragrance component of the defecation part will evaporate. The guardian can distinguish between urination and defecation.

  Here, there is no particular limitation as to where the planar positions of the urine receiving portion and the toilet receiving portion on the disposable diaper 10 are. It can be set as appropriate, for example, by taking statistics of the urination site or the defecation site. In general, the ventral side from the crotch region is the urine receiving part, and the back side from the crotch region is the toilet part.

  On the other hand, the member (so-called cross-sectional position) serving as the object (target) of the microcapsules 5A, 5B... Is not particularly limited. A member constituting the disposable diaper 10 is sufficient, and the microcapsules 5A, 5B,... Therefore, for example, as shown in FIG. 3, it can be applied to the surface 11 a (the urine receiving portion and the feces receiving portion) of the surface side sheet 11. However, according to this embodiment, the microcapsules 5A, 5B,... May fall off or cause rough skin.

  Therefore, from the viewpoint of preventing these, it is preferable to apply to the surface 31a of the absorber 31 (in this embodiment, between the absorber 31 and the surface portion 32A of the covering sheet 32). Further, from the viewpoint of preventing the movement of the microcapsules 5A, 5B... In the planar direction, the urine storage recess 6A and the stool storage recess are formed on the surface 31a (surface layer) of the absorber 31, as shown in FIG. 6B is provided, and microcapsules 5A, 5B... Are preferably provided in the recesses 6A, 6B. In the embodiment in which the microcapsules 5A, 5B,... Are applied to the surface 31a of the absorber 31, for example, the microcapsules 5A, 5B,. Although it is necessary to fix with hot melt adhesive etc., in this form, this fixation can also be abbreviate | omitted. Further, since urine or stool is stored in the urine storage recess 6A and the stool storage recess 6B, the contact between the microcapsules 5A, 5B... And urine or stool is not instantaneous. Therefore, the wall material of the microcapsules 5A, 5B. If the wall materials of the microcapsules 5A, 5B,... Are hardened, the microcapsules 5A, 5B, which are not assumed when the microcapsules 5A, 5B,... Are heavily loaded or the humidity in the paper diaper 10 is increased. ... collapse is prevented.

  Here, the fixed amount of the microcapsules 5A, 5B,... Can be changed by changing the depth and diameter of the urine storage recess 6A and the feces storage recess 6B. Therefore, it is also a preferred form that the difference in odor due to urination, defecation, etc. is made larger by making the depth and diameter of the concave portion 6A for urine storage and the concave portion 6B for stool accommodation different from each other.

  As described above, in this embodiment, the microcapsules 5A, 5A... Of the urine receiving part and the microcapsules 5B, 5B... Of the stool receiving part are both the surface 11a of the surface side sheet 11, the surface 31a of the absorber 31, or the recess 6A. Although the form given to 6B was shown, it is not the meaning limited to this. For example, the urine receiving portion microcapsules 5A, 5A,... Are applied to the surface 31a of the absorber 31, the stool receiving portion microcapsules 5B, 5B,. You can also.

  By the way, when the microcapsules 5A, 5B... Are applied to the urine receiving part or the stool receiving part of the absorber 31, in the previous example, the urine receiving part or the stool receiving part of the surface 31a of the absorber 31 or the urine storage In the case of being applied to the recess 6A or the stool receiving recess 6B, as shown in FIG. 6 as an example of the case of being applied to the recesses 6A, 6B, Urine guide ports 7A, 7A and stool guide ports 7B, 7B reaching the recessed portion 6B or the recessed portion 6B (the receiving portion of the absorber 31) are preferably formed. According to this embodiment, urine is reliably separated and stored in the urine storage recess 6A and stool is stored in the stool storage recess 6B. It will be something.

  At this time, the surface side sheet 11 to be formed is not particularly limited. At least one of the top sheet 1, the second sheet 4, and the surface portion 32 </ b> A of the cover sheet 32 can be formed.

  On the other hand, similarly to the above, in the case where the microcapsules 5A, 5B,... Are applied to the urine receiving part or the stool receiving part of the absorbent body 31, the case where the micro capsules 5A, 5B,. Thus, between the recess 6A (the urine receiving portion of the absorber 31) and the recess 6B (the stool receiving portion of the absorber 31), for example, a separation sheet 31A that is impermeable to bodily fluids is provided, so that urine, feces, etc. It is preferable that no excrement is distributed. According to this embodiment, after the urine is separated and stored in the urine storage recess 6A and the stool is separately stored in the stool storage recess 6B, the stool diffuses to the urine storage recess 6A, or the urine is stored in the stool storage recess 6B. The transpiration of the fragrance component according to the urination and defecation is more reliable.

  At this time, from the viewpoint of ease of manufacture, it is also preferable to separate the urine receiving portion side absorber 31 and the toilet portion side absorber 31 separated by the separation sheet 31A. Regardless of whether or not they are separate, for example, the density, fiber direction, and the amount of absorption polymer applied to each other may be different from each other to provide absorption performance according to the characteristics of defecation and urination. This is a preferred form.

In this embodiment, the top sheet 1 has a property of permeating body fluid. Therefore, the material of the top sheet 1 is sufficient if it exhibits this body fluid permeability, and examples thereof include a porous or non-porous nonwoven fabric and a porous plastic sheet. Of these, the nonwoven fabric is not particularly limited as to what the raw fiber is. For example, olefins such as polyethylene (PE) and polypropylene (PP), polyesters, polyamides and other synthetic fibers, regenerated fibers such as rayon and cupra, natural fibers such as cotton, etc. are used. The mixed fibers can be exemplified. Furthermore, the nonwoven fabric may be manufactured by any processing. Examples of the processing method include known methods such as a spunlace method, a spunbond method, a thermal bond method, a melt blown method, and a needle punch method. For example, the spun lace method is a preferable processing method when the flexibility and drape properties are required, and the thermal bond method is the preferable processing method when the bulkiness and softness are required.
Moreover, the top sheet 1 may be composed of a single sheet or may be composed of a laminated sheet obtained by bonding two or more sheets. Similarly, the top sheet 1 may be composed of one sheet or two or more sheets with respect to the planar direction.

(Second sheet 4)
The second sheet 4 has a property of diffusing and transmitting body fluid. Therefore, the material of the second sheet 4 is sufficient if it exhibits this body fluid diffusion / permeability, and examples thereof include the same material as the top sheet 1. However, for example, spunlace, pulp nonwoven fabric, mixed sheet of pulp and rayon, point bond or crepe paper is preferable. Further, the second sheet 4 is particularly preferably one having better body fluid permeability than the top sheet 1, and has a fiber density smaller than that of the top sheet 1, for example, polypropylene, polyethylene, polyethylene terephthalate, polyamide, nylon, rayon, vinylon, A nonwoven fabric made of acrylic or the like is particularly preferable.

(Absorber 31)
Examples of the absorbent 31 include those in which a granular absorbent polymer is mixed in a fluffy pulp fiber aggregate (stacked pulp).
As an absorptive polymer, what absorbs and hold | maintains a bodily fluid 10 times or more of own weight can be used. Examples of this include starch-based, cellulose-based and synthetic polymer-based ones, such as starch-acrylic acid (salt) graft copolymer, starch-acrylonitrile copolymer saponified product, sodium carboxymethylcellulose crosslinked product, An acrylic acid (salt) polymer or the like can be used. The shape of the absorbent polymer is preferably a granular material that is usually used, but other shapes can also be used.

On the other hand, the raw material of the piled pulp is not particularly limited. For example, known materials such as cotton-like pulp and synthetic pulp can be exemplified. Moreover, the raw material fiber of a pulp is not specifically limited, For example, the cellulose fiber obtained from woods, such as a mechanical pulp, a chemical pulp, and a dissolving pulp, Artificial cellulose fibers, such as rayon and an acetate, etc. can be illustrated. However, the wood used as the raw material for cellulose fibers is more preferable in terms of function and price because conifers have longer fiber lengths than hardwoods.

(Coating sheet 32)
In the present embodiment, the material of the covering sheet 32 is not particularly limited as long as it has a property of transmitting body fluid. For example, the same material as exemplified as the top sheet 1 can be used. Specifically, for example, a body fluid permeable sheet such as a crepe paper, a nonwoven fabric, or a perforated sheet can be used.

(Back sheet 3)
In this embodiment, the back sheet 3 has a property of not transmitting body fluid. Therefore, the material of the back sheet 3 is sufficient if it exhibits this body fluid impermeability, for example, an olefin resin such as polyethylene or polypropylene, a laminated nonwoven fabric in which a nonwoven fabric is laminated on a polyethylene sheet, or a waterproof sheet is interposed. Non-woven fabrics such as exterior sheets that are substantially impervious to liquid (in this case, the back sheet 3 that is impermeable to body fluids is composed of a waterproof sheet and non-woven fabrics such as exterior sheets). be able to. Of course, in addition to this, materials having liquid impermeability and moisture permeability, which have been used and used in recent years from the viewpoint of preventing stuffiness, can also be exemplified. As the sheet of the material having liquid impermeability and moisture permeability, for example, an inorganic filler is kneaded in an olefin resin such as polyethylene or polypropylene, and the sheet is formed, and then stretched in a uniaxial or biaxial direction. Examples of the microporous sheet obtained in this way can be given.

(Microcapsules 5A, 5B)
The microcapsules 5A and 5B of the present embodiment have a property that a core material such as a fragrance component flows out when contacted with excrement such as urine and feces. The mechanism by which the core material such as the fragrance component flows out is not particularly limited. For example, if the liquid in the excrement is sucked, the wall material breaks, if the liquid in the excrement is sucked, the wall is swollen to open the pores formed in the wall, and the liquid in the excrement And the form in which the wall material elutes. Moreover, it can change to the form by absorption of such a liquid component, and can also illustrate the form which the same phenomenon produces by the heat receiving by contact with excrement, and pH change.
Examples of the wall material of the microcapsules 5A and 5B include gelatin, agar, various natural gelling agents, glycerin and the like. The structure of the capsule is not particularly limited, and for example, a simple mononuclear structure can be exemplified.
Furthermore, the shape of the microcapsules 5A and 5B is not particularly limited. However, it is preferable that the shape has no protrusion so as not to give the wearer a sense of foreign matter.
On the other hand, the size of the microcapsules 5A and 5B is not particularly limited. From the viewpoint of preventing the wearer from feeling foreign matter, the design can be made as appropriate. From the viewpoint of preventing foreign matter, it is usually 0.1 to 1000 μm, preferably 1 to 50 μm.

(Fragrance ingredient)
In this embodiment, at least two kinds of perfume ingredients are necessary, and the perfume ingredients need to be different perfume ingredients to such an extent that the supervisor or the like can distinguish and know whether they are urinating or defecation. But what kind of individual fragrance | flavor ingredients are is not specifically limited. For example, rose, lavender, mint, lemon and the like can be exemplified, and these fragrance components may be natural extracts or synthetic products. Further, in terms of function, the perfume component may have a deodorizing effect that eliminates urine and stool odors. It may have a masking effect that makes it impossible to recognize the smell of urine and feces.

(Other core materials)
(1) In this embodiment, it is preferable to include a lotion chemical solution together with a perfume component. When a lotion chemical solution is contained together with the fragrance component, the touch (texture), moisturizing property and moisturizing feeling are increased, or the irritation to the skin by the fibers of the top sheet 1 is alleviated.

The type is not particularly limited. For example, as the moisturizing chemical solution, at least one moisturizing agent selected from polysiloxanes such as silicone oil and silicone powder, polyhydric alcohols such as glycerin and propylene glycol, saccharides such as sorbitol and glucose, glycol solvents, and derivatives thereof. The thing using what contains this can be illustrated. Moreover, the above chemical | medical solution can use together the chemical | medical solution containing vitamin C, vitamin E, collagen, etc., for example. This type of chemical has a function to enhance the feeling of moisture. Vitamin C and vitamin E also function as antioxidants. Vitamin E is a component with a strong reducing power and has an antioxidative action that eliminates active oxygen and free radicals or prevents the generation of lipid peroxide. Therefore, vitamin E functions as a chemical liquid stabilizer, and exhibits an antioxidative effect on skin sebum and a blood circulation promoting effect. There is also a moisturizing function. Vitamin C, like vitamin E, has a sebum antioxidant effect. Vitamin C has the action of reducing vitamin E. If both vitamin C and E are used, vitamin C works as an auxiliary to vitamin E and reduces vitamin E oxidized by active oxygen. The effect | action which maintains the antioxidant effect | action of the powerful sebum of E is show | played. Collagen forms 90% of the dermis of the skin, and when this decreases, the skin loses moisture and tension. Therefore, it exhibits a moisturizing effect that moisturizes the skin when it comes into contact with the skin. Moreover, as a chemical | medical solution, especially when it is made into the weak acidity of pH 5.0-6.0, even if it makes it contact with skin, skin does not become alkalinity, and the rough skin by the influence of chemical | medical solution pH Can be effectively prevented. A particularly preferred pH range is 5.3 to 5.7. As a method for adjusting the pH, it can be carried out by adding an acidic or basic pH adjusting agent to the chemical solution.

  As the cationic surfactant, a quaternary ammonium salt, an amine salt, an amine, or the like can be used. In addition, as the zwitterionic surfactant, an aliphatic derivative of a secondary or tertiary amine containing carboxy, sulfonate, sulfate, an aliphatic derivative of a heterocyclic secondary or tertiary amine, or the like is used. be able to.

  As described above, in this embodiment, various lotion chemicals can be used. In particular, liquid paraffin 5 to 20%, polyhydric alcohols 50 to 85%, saccharides 3 to 30%, and further if necessary. It is preferable to use a chemical solution containing 5% or less of a nonionic surfactant as a main ingredient. When the amount of liquid paraffin added is less than 5%, the moist feeling is lowered, and the smoothness is lowered and rough. On the contrary, if it exceeds 20%, it gives a sticky feeling (sticky feeling), and also gives a rough feeling and a harder feeling. A more preferable range is 8 to 15%.

  The amount of polyhydric alcohol added is 50 to 85%. If it is less than 50%, the wiping effect and moist feeling are inferior. If it exceeds 85%, the amount of other components added is decreased, and the balance of the overall characteristics is deteriorated. In addition, the strength is deteriorated, it becomes easy to tear, and gives a sticky feeling. The polyhydric alcohol is particularly preferably composed of glycerin, propylene glycol or a mixture thereof.

  The amount of saccharide added is 3 to 30%. If it is less than 3%, the moist feeling and softness are lowered, and if it exceeds 30%, the balance of the overall characteristics is deteriorated, the strength is deteriorated, and it is easily broken. As the saccharide, those composed of sorbitol or glucose or a mixture thereof are particularly suitable.

  Further, if necessary, 5% or less of a nonionic surfactant can be added. Nonionic active agents include sorbitan fatty acid esters, diethylene glycol monostearate, diethylene glycol monooleate, glyceryl monostearate, glyceryl monooleate, propylene glycol monostearate and other polyhydric alcohol monofatty acid esters, N- (3-oleoxy -2-hydroxypropyl) diethanolamine, polyoxyethylene hydrogenated castor oil, polyoxyethylene sorbit beeswax, polyoxyethylene sorbitan sesquistearate, polyoxyethylene monooleate, polyoxyethylene sorbitan sesquistearate, polyoxyethylene glyceryl mono Oleate, polyoxyethylene monostearate, polyoxyethylene monolaurate, polyoxyethylene monooleate, poly Carboxymethyl ethylene cetyl ether, and polyoxyethylene lauryl ether.
