BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pain-resistant disposable absorbent article, and more particularly to a solid absorbent in a disposable absorbent article composed of a liquid permeable topsheet, a liquid impermeable backsheet, an absorber, an outer flap, and a barrier cuff (leg standing cuff). The present invention relates to a disposable absorbent product having excellent skin safety by removing both side flaps outside the band to free ventilation between the inside and the outside when the disposable absorbent product is worn.

In general, disposable absorbent products include absorbent products for babies or incontinents who are unable to process excretion excreted or excreted by physiological action by themselves, and are a generic term for diapers, sanitary napkins, and the like.

In the present invention, as a disposable absorbent product, a panty-type disposable diaper for infants and incontinence is given as an example. In general, the performance of disposable diapers is evaluated according to the rate of absorption, absorption, amount and skin stability of the discharge, and excellent skin stability should be absorbed as soon as the secretion is secreted. Therefore, diaper rash such as red spots or skin irritation should not occur on the skin.

Conventional disposable absorbent articles shown in FIGS. 3 and 4 have a liquid impermeable backsheet 1, a liquid permeable topsheet 2, an absorber 3, an outer flap 9 and a solid band 10. Absorption characteristics such as absorption rate and absorption amount reaches a high level of technology due to the development of super absorbent polymer, whereas the toxic gases accompanying fluid excretion are combined to cause diaper rash such as skin rash and red spots. have. As a fundamental cause of diaper rash, the structure in which water vapor and toxic gases accompanying fluid excretion do not come out, that is, the thigh area and the outer flap 9 are in close contact with each other when the diaper is worn, so that the diaper inside and the outside period Impossible to increase the temperature and humidity inside the diaper, this is due to the swelling of the skin surface of the weak babies (swelling), the penetration of toxic gases such as ammonia and skin bacteria act on the weakened skin.

As a method for solving such a conventional problem, Korean Patent Publication No. 90-5652 attempts to prevent and remove skin rashes by adding baby powder among the components of a disposable absorbent product, but the addition of baby powder can solve these problems. Was not. In other words, the disposable absorbent product is wetted with the urine of the baby, the elements contained in the urine are decomposed by the high temperature inside the diaper and the bacteria present in the skin to produce ammonia, but the baby powder is composed of a generally porous material Therefore, the amount of ammonia produced was somewhat reduced. However, since it is still impossible to ventilate the water vapor from the urine with the outside, diaper rash could not be fundamentally removed.

Therefore, since the inside and outside of the diaper when wearing a disposable absorbent product has a special structure that can be ventilated with each other, development of disposable absorbent products excellent in skin stability of babies has been expected.

The present invention has been devised accordingly, an object of the present invention is to remove or minimize the outer flap of the coagulation band to ventilate the inside and outside of the diaper when worn, thereby providing a disposable absorbent product with excellent skin safety (Skin safety). It is.

Disposable absorbent articles of FIGS. 1 and 2 according to the present invention are a liquid impermeable back sheet 1, a liquid permeable top sheet 2, an absorbent body 3 made of downy pulp or superabsorbent resin, and an outer flap 9 And a solidifying band 10 composed of the wall 7 and the contact surface 8. The liquid impervious back sheet 1 may use either a conventional non-breathable waterproof film or a breathable waterproof film. The solidifying band 10 is a waterproof breathable nonwoven fabric, the material of which is polypropylene, and the spunbond type is a spunbond type having a basis weight of 15 to 23 g. The outer flap 9, which is in close contact with the thigh area when the diaper is worn, was manufactured with its length less than 0 to 5 mm. By removing or minimizing the outer flap as described above, when the disposable absorbent product is worn, the skin 7 directly contacts the wall 7 of the coagulation band 10 so that the outside air is ventilated through the wall 7 warmed by the body temperature of the skin itself. . Therefore, even if the diaper is worn for a long time, the outside temperature is similar to the inside temperature of the diaper by ventilation, and the diaper internal environment is always maintained in a comfortable state, and the diaper rash such as skin sores and skin rashes is essential as long-term wear of disposable absorbent products. Can be prevented.

Hereinafter, the present invention will be described in more detail with reference to Examples.

Example 1

100 babies 3-12 months old with a disposable absorbent product of 0 mm without any outer flap of the clot band of a conventional disposable absorbent product consisting of a liquid impermeable backsheet, a liquid permeable topsheet, an absorbent and a coagulation band. 3 hours after wearing, the spatial humidity and temperature between the disposable absorbent product and the baby's skin were measured with a Thermotracer, and the results are shown in Tables 1 and 2. In addition, the diaper rash rate after direct wearing for 6 months was calculated, and the results are shown in Table 3.

Example 2

Except having made the outer flap of the coagulation band into 5 mm, it configured and measured similarly to Example 1, and the result was shown to Table 1, Table 2, and Table 3.

Comparative Example 1

The composition was measured and constructed in the same manner as in Example 1 except that a conventional disposable absorbent product consisting of a liquid impermeable backsheet using a non-breathable film, a liquid permeable top sheet, an absorbent body, a coagulation band, and an outer flap of the coagulation band was used. Table 1, Table 2 and Table 3 are shown.

Comparative Example 2

The liquid-impermeable backsheet was configured and measured in the same manner as in Comparative Example 1 except that a breathable film was used, and the results are shown in Tables 1, 2, and 3, respectively.

Comparative Example 3

Except having added 1g of baby powder, it configured and measured similarly to the comparative example 2, and the result was shown to Table 1, Table 2, and Table 3.

[Comparative Example 4]

Except having made the coagulation band outer flap into 6 mm, it configured and measured similarly to the comparative example 1, and the result was shown to Table 1, Table 2, and Table 3.

TABLE 1

Note) [++] is less than 30 ℃ (temperature required for skin sores prevention)

[+] Is 31 to 33 ° C (good temperature for skin sores prevention)

[±] is 34 to 35 ° C (temperature at which skin sores may occur)

[-] Is more than 36 ℃ (temperature excellent for skin sores)

As shown in the results of Table 1, compared with Comparative Examples 1 to 4, in Examples 1 and 2, the air in the diaper was ventilated to the outside through the wall of the coagulation band, so that the occurrence of skin sores was significantly reduced.

TABLE 2

Note) [++] is less than 70% humidity

[+] Is 70 to 80% humidity

[±] is 81 to 90% humidity

[-] Is humidity above 90%

As compared with the results of Table 2, Examples 1 and 2 compared with Comparative Examples 1 to 4, the air inside the diaper is ventilated to the outside through the wall of the coagulation band, thereby keeping the state inside the diaper comfortably.

TABLE 3

Note) [++] has no diaper rash at all

[+] Has some red spots

[±] is a strong red spots and swelling gradually formed

[-] Has red spots and wide spread sores

As described above and the results in Table 3, in comparison with Comparative Examples 1 to 4, Examples 1 and 2 significantly reduced the incidence of diaper rash.

As described above, in view of the incidence rate of diaper rash according to the humidity and temperature of the space between the skin and the disposable absorbent product when wearing the disposable absorbent product, Examples 1 and 2 are known disposable absorbent products of Comparative Examples 1 to 4. Compared to this, it can be seen that it has an excellent performance.

In the present specification, although the diaper is employed as an embodiment of the disposable absorbent product, it will be understood that the present invention is not limited thereto.
