DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to an absorbent article intended for use as a urine-collecting insert in a disposable diaper or an incontinence guard, said article including an inner casing layer of liquid permeable material which lies nearest the body of the wearer in use, an outer liquid permeable casing layer, and an absorbent body or pad enclosed between said casing layers.
BACKGROUND OF THE INVENTION
An adult incontinence guard must be adapted to the type of incontinence for which it is to provide a guard. In milder forms of incontinence where only small quantities of fluid are discharged, a thin, small guard may suffice to protect the underwear of the wearer, whereas heavier incontinence will require diapers of high absorption capacity and leakage reliability. Furthermore, for anatomical reasons, male and female incontinence guards must be configured differently. The specific problems encountered when configuring male incontinence guards reside primarily in the tendency of the male penis to move readily in the guard, or to be positioned incorrectly when putting on the guard. Consequently, in the case of known male incontinence guards, it is impossible to anticipate that region of the guard in which wetting will primarily occur. In the case of female incontinence guards, on the other hand, a so-called wetting point can be determined more readily, and, consequently, it is easier to optimize the absorption capacity of female incontinence guards.
Leakage will often occur in known male incontinence guards because urine has either been delivered to one side of the guard or to random regions thereof. Because the urine has been absorbed within random regions of the incontinence guard, parts of the absorption material will have become saturated with liquid, resulting in leakage, whereas other parts of the absorption material will have remained unused.
SUMMARY OF THE INVENTION
As a result of the present invention, there is provided an article of the kind mentioned in the introduction which reduces the risk of leakage when large quantities of urine are discharged. The inventive article is primarily characterized in that the outer casing layer has a lower liquid permeability than the inner casing layer, and, consequently, liquid absorbed in the article is able to pass to the outer casing layer in a relatively slow and controlled fashion, and collect in the diaper or incontinence guard.
The inventive article can be used by both men and women, and therewith solves the particular problems mentioned above and associated with the use of male diapers or incontinence guards.
When the inventive article is used by men, the article is placed over the genitals of the wearer. A conventional, adult diaper is normally placed externally of the article, with respect to the wearer. The article receives all urine that is discharged, said urine being transferred progressively to the externally located diaper as the absorbent pad of the article becomes saturated. The diaper is thus able to slowly absorb the liquid transported from the article.
According to one embodiment of the invention, the outer casing layer of the article is divided into zones of mutually different degrees of liquid permeability. This affords the possibility of guiding the liquid absorbed by the article to selected parts of the diaper which exhibit particularly high absorption capacities or liquid dispersion ability, besides affording an additional guard against limited regions of the diaper becoming quickly saturated with liquid and therewith causing leakage.
BRIEF DESCRIPTION OF THE DRAWINGS
The invention will now be described in more detail with reference to an exemplifying embodiment thereof illustrated in the accompanying drawings, in which FIG. 1 illustrates one embodiment of an inventive article in a stretched or extended state, with the side intended to lie against the wearer in use facing towards the viewer, and FIG. 2 is a perspective view of the article illustrated in FIG. 1 with the elastication active; while FIG. 3 il
