DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to a disposable absorbent pants product.
BACKGROUND OF THE INVENTION
A disposable diaper product of this type is shown and described in EP-A 357 298, where an inner envelope, which may be a polyolefine sheet with perforations to allow urine to pass through, is provided with an aperture to allow feces to pass through. The envelope is provided with elastic strands to hold it in place against the wearer's body. Outside the elasticized envelope, the diaper is provided with absorbent material and an outer jacket of liquid-impermeable material, which is attached to the inner envelope only at the waist edges and the leg edges of the diaper. When filled with urine and feces, the absorbent material and the outer jacket will hang down between the legs of the wearer, decreasing comfort and security against leakage. When the absorbent material is deformed in the narrow space between the user's legs the elasticized envelope can often be forced away from correct contact with the skin of the user, giving rise to folds and creases and leakage can then occur.
The problem of keeping a diaper in place has been approached in many different ways. Elastic side panels for example are described in EP-A 320 991. SE 425 942 describes the placement of elastic means in a V-shaped pattern to hold the liquid permeable layer of the diaper in better contact with the user's body. Neither of these known solutions is completely satisfactory as regards holding the product in place to prevent leakage and neither of them addresses the problem at all of keeping urine and feces out of contact with the user's skin.
SUMMARY OF THE INVENTION
These problems are satisfactorily solved by a disposable absorbent pants product in accordance with the present invention.
According to the present invention, a disposable absorbent article to be worn by an individual possessing an anus and a urethral opening includes an elastic pant provided with a first hole adapted to be located at the anus of the individual when the article is worn by the individual and a second opening adapted to be located at the urethral opening when the article is worn by the individual. The first hole is separate from the second hole. An outer liquid impermeable cover covers the first hole to form a first pocket for receiving feces, and an outer liquid impermeable cover covers the second hole to form a second pocket for receiving urine.
BRIEF DESCRIPTION OF THE DRAWING FIGURES
The present invention will now be described with reference to examples shown in the accompanying figures of which:
FIG. 1 shows a pant diaper according to the invention in its extended state just prior to final assembly as seen from the inside of the pant diaper,
FIG. 2 shows the pant diaper according to the present invention in its extended state just prior to final assembly as seen from the outside,
FIG. 3 shows the pant diaper according to the present invention after final assembly as worn by a child.
DETAILED DESCRIPTION OF THE INVENTION
The pant diaper according to the invention as shown in the figures is essentially based on an elastic pant 1 composed of an elastic net or film covered with substantially liquid-permeable and air-permeable, e.g. hydrophobic, layers of non-woven material. The elastic pant is provided with a hole 2 which, when the pant is worn, will be placed directly at the urethral opening. The placement and size of said hole 2 may be adapted to the sex and/or age of the intended wearer. The pant is also provided with a hole 3 which will be placed directly at the anus when worn.
As can be seen most clearly in FIG. 2, cover layers 4, 5 of liquid impermeable material such as polyethylene film or a hydrophobic nonwoven fabric cover each of the holes and are sealingly fixed (as indicated by reference numeral 8) to the elastic pant thereby forming a pocket around each of said holes 3 and 2 respectively. According to preferred embodiments each pocket can be filled with absorbent material 6, 7 such as fluff pulp and/or superabsorbent
