The present invention relates to a disposable diaper for informing the wearer or guardian of urination.

Disposable absorbent articles, such as infant disposable diapers or adult disposable diapers, are highly absorbent and can effectively remove moisture from the wearer to reduce skin irritation that may be caused by prolonged exposure to moisture. However, because these products are so absorbent, they are not able to determine if they are urinated when worn by immature infants or elderly dementia patients who do not recognize the meaning of the body sensation associated with urination, and thus the caregiver fails to control urination. It is not possible to know that it has been done or that the diaper needs to be replaced. In this case, in order to determine urination, the diaper should be directly touched or naked with the wearer's clothes removed, but this is inconvenient.

If the used diaper is insufficiently absorbent or has a large amount of urination, the wearer will be exposed to a humid environment for a long time. Such exposure may cause skin irritation and dermatitis. Very important (see Korean Patent Application No. 10-2001-0041853).

In addition, infants in the toilet urination practice need to facilitate the toilet urination practice by more easily aware of the urination to the infant. The prior art for achieving this purpose includes a diaper containing a temperature change element that causes a change in temperature after the wearer's urination and makes the wearer feel it, and an element that changes in size to immediately expand into the crotch region of the wearer after urination. Diapers, diapers that have high initial surface moisture immediately after urination, but soon afterwards remove moisture from the wearer, but the manufacturing method is complicated and the wearer feels urination through unfavorable stimuli such as temperature, pressure, and moisture, respectively. There is a disadvantage to that. In this case, the infant in urination practice has a negative image of urination itself, which makes it very difficult for the infant to practice urination.

Korean Patent Application No. 10-2004-7009296 discloses a diaper containing a wet indicator to inform a wearer of urination by using a difference in stiffness of a liquid absorber that absorbs urination, but the manufacturing method is complicated. Guardians such as parents have the disadvantage that it is difficult to know the urination.

On the other hand, aromatic plants or fragrances prepared using them have been known to have various psychological and physiological effects on the human heart and body. Clinically, the psychological effects of fragrances have been tested, and it has become clear that olfactory stimuli regulate the systemic immune system (see Komori et al., Neuroimmunomodulation 2: 174-180 and Shibata et al., Intern J Neuroscience 51: 245-247). The application of these fragrances is increasing.

Therefore, the technical problem to be achieved by the present invention is to provide a disposable diaper for the wearer or protector to easily grasp the urination of the diaper with a positive feeling.

Another technical problem to be achieved by the present invention is to provide a disposable diaper capable of making timely replacement of the disposable diaper and minimizing the skin irritation by containing a beneficial substance in the skin irritation.

In order to achieve the above technical problem, the present invention provides a disposable diaper informing the fact of urination containing a volatile flavor. More specifically, the present invention provides a disposable basal ear that informs of urination containing volatile flavors coated with a water soluble polymer.

In another aspect, the present invention provides a disposable diaper that informs the user of urination that can prevent skin irritation or dermatitis by using a volatile flavor having a beneficial effect on skin irritation such as antihistamine action as the aforementioned volatile flavor.

Hereinafter, a disposable diaper containing the volatile flavor of the present invention, informing diaper urination facts will be described in detail.

The disposable diaper of the present invention provides a disposable diaper which indicates the diaper urination fact, which contains a volatile flavor. Disposable diapers informing the fact of urination of the present invention is that the fragrance is volatilized by the moisture generated during urination, so that the wearer or guardian can sense the fragrance and recognize that the wearer has urinated and replace the disposable diaper. Based on facts

The present invention is also very difficult to store due to the volatility of the fragrance when the conventional liquid volatile fragrance is contained in the diaper and this problem is a water-soluble polymer that can dissolve the volatile fragrance and quickly dissolve upon contact with moisture volatile fragrance It is based on the amazing fact that it can be solved by coating it.

In one embodiment of the present invention, a solid perfume which is not coated with a water-soluble polymer which rapidly increases its volatility upon contact with moisture as the above-mentioned volatile perfume may be used. However, in view of non-volatile during storage, achieving the object of the present invention, it is preferable to use a volatile perfume coated with a water-soluble polymer rather than such an uncoated solid perfume. As the volatile perfume, both solid and liquid perfumes can be used.

In one embodiment of the present invention, a volatile perfume coated with a water-soluble polymer can be prepared using a coating device used in the pharmaceutical field to coat the raw material with a polymer. As a coating device that can be used, a fluidized bed granulator, a spray dryer, a C / F granulator, etc. may be used, but is not limited thereto.

In a preferred embodiment of the present invention, the volatile perfume coated with the water-soluble polymer contained in the disposable diaper for informing urination may further contain a high swellable adsorbent with the volatile perfume inside the coated polymer. In other words, in the case of containing a coating fragrance prepared by coating a 'volatile scent and a high swellable adsorbent' together with a water-soluble polymer, water generated during urination is adsorbed to the high swellable adsorbent by passing through the coating membrane, and then high swellable adsorption. As the material expands, it further promotes the volatilization of volatile flavors. In addition, the highly swellable adsorbent has the advantage of reducing the skin irritation of the wearer by adsorbing toxic substances generated during urination.

As used herein, the term "highly swellable adsorbent" means a material capable of absorbing or adsorbing moisture to expand, and such highly swellable adsorbents include zeolite, bentonite, croscarmellose sodium, crospovidone, and low-substituted hydroxypropyl. Cellulose, sodium starch glycolate, crystalline cellulose, sodium alginate, sodium carboxymethyl cellulose, pectin, tragacanth rubber and the like can be used. Zeolites or bentonites are more preferred in terms of expandability, adsorption, and ease of coating process.

In one preferred embodiment of the present invention, the 'volatile flavor and high swellable adsorbent' coated with a water-soluble polymer first adsorbs the volatile flavor (liquid) to the high swellable adsorbent, or the volatile flavor is solid and swellable. It can be prepared by mixing evenly, micronizing this (if necessary) and then coating it with a water soluble polymer using the above-mentioned coating apparatus.

As used herein, the term "coating" means that the volatile flavor is surrounded or mixed with a water soluble polymer to prevent volatility of the aforementioned volatile flavor. The coated volatile fragrance of the present invention is preferably completely coated to completely block the volatilization of the fragrance, but need not be completely coated within the scope that does not impair the object of the present invention. That is, the present invention includes a disposable diaper which indicates the urination fact that contains the volatile perfume which has been manipulated or treated to make the volatile perfume less volatile.

As the water-soluble polymer for coating the 'volatile flavor' or 'volatile flavor and high swellable adsorbent' of the present invention, hydroxymethyl cellulose, hydroxyethyl cellulose, hydroxyethyl methyl cellulose, hydroxypropyl methyl cellulose, carboxy Methyl cellulose, polyvinyl alcohol, polyvinylpyrrolidone and the like can be used, and hydroxypropyl methyl cellulose is preferred in view of solubility and ease of manufacture when in contact with water.

As the volatile perfume of the present invention, a solid volatile perfume or a liquid perfume coated with a water-soluble polymer that dissolves in contact with water may be used, but is not limited thereto.

In one preferred embodiment of the present invention, as the volatile perfume of the present invention, a volatile perfume having a function of suppressing skin irritation may be used. Volatile flavors known to inhibit skin irritation include citralva, lemon oil, jasmine, rosemary, rooibos, isobornyl acetate, peppermint, basil Robe flavoring, star anise flavoring, etc. may be used, but is not limited thereto. Jasmine flavor known to be effective in dry sensitive skin and rosemary flavor known to soften the skin are more preferred, and volatile flavors prepared using Rooibos, which is known to be effective in treating dermatitis and to remove histimin. Most preferred.

Conventional disposable diapers consist of a liquid permeable surface sheet that comes into contact with the wearer's skin, an absorbent consisting of downy pulp, a superabsorbent resin and / or tissue, and a liquid impermeable backsheet. In a preferred embodiment of the present invention, the volatile perfume coated with the water-soluble polymer of the present invention is preferably located directly below the liquid permeable surface sheet. In one embodiment of the present invention, the volatile fragrance coated with the water-soluble polymer of the present invention is contained in a liquid permeable bag and attached to a disposable diaper. In particular, in one preferred embodiment of the present invention for mass production, the volatile fragrance coated with the water-soluble polymer of the present invention is sprayed mixed with the pulp constituent material during the spraying process to produce the fluffy pulp, and coated with the volatile fragrance The adhesiveness of the water-soluble polymer used in order to be evenly mixed with the downy pulp.

Hereinafter, the present invention will be described in more detail with reference to Examples and Experimental Examples. However, it is well known that the scope of the present invention is not limited by the following examples, and those skilled in the art may make various modifications within the scope of the spirit of the present invention.

< Experimental Example  1-1> Simple Evaluation of Effects

100 ml of normal tap water was evenly spread on the surface sheet of the disposable diaper prepared in Example 2-1 and Example 2-2, and the occurrence of fragrance was evaluated at a distance of 20 cm. Five testers each tested ten disposable diapers, and were able to detect the scent that occurs in the tested disposable diapers.

< Experimental Example  1-2> Infant Wear Assessment

Ten infants with skin irritation were evaluated using the disposable diaper prepared in Example 2-2 to determine whether fragrance occurred and the degree of improvement of skin irritation.

The fragrance was assessed by whether the guardian perceived the fragrance as a sense of smell. As a result, all the subjects were aware of the fragrance of the infant during urination, which speeds up the replacement cycle of the disposable diapers.

The improvement of skin irritation was evaluated by the following method. Before wearing the disposable diaper of the present invention, the same disposable diaper without commercial volatile flavor was first used for 10 days to record the degree of skin irritation. Skin irritation was evaluated as a score of 5 for severe skin irritation, 4 for severe skin irritation, 3 for normal skin irritation, 2 for mild skin irritation, and 1 for no skin irritation. The skin irritation was evaluated after 10 days of use of the usual disposable diaper, and after that the disposable diaper prepared in Example 2-2 was used for 10 days, and then the skin irritation was reevaluated based on the same criteria. The results are shown in Table 1.
