Class Int. Class Application Number: Lodged: Complete Specification Lodged: Accepted: Published: Priority Related Art: c s a o D r a o o o r o a Name of Applicant: Uni-Charm Corporation Actual Inventor(s): Takamitsu Igaue Kohji Inoue Tsutomu Kido Address for Service: PHILLIPS ORMONDE FITZPATRICK Patent and Trade Mark Attorneys 367 Collins Street Melbourne 3000 AUSTRALIA Invention Title: DISPOSABLE DIAPERS Our Ref 332801 POF Code: 1647/76530 The following statement is a full description of this invention, including the best method of performing it known to applicant(s): DISPOSABLE DIAPERS BACKGROUND OF THE INVENTION This invention relates to disposable diapers adapted to absorb and hold body exudates such as urine and excretions.
Japanese Patent Application Disclosure Gazette No.
1991-231664 discloses a disposable diaper comprising a first liquid-permeable topsheet, a liquid-impermeable backsheet, a liquid-absorbent panel sandwiched between these sheets and a second liquid-permeable topsheet overlaid on said first liquid-permeable topsheet and bonded at longitudinally opposite ends thereof to said first topsheet.
S. In the diaper disclosed in the above-identified patent application, it is intended to put the second liquidpermeable topsheet in contact with a wearer's skin over the crotch zone so as to reliably hold excrements. However, depending on particular characteristics of excretions (or feces) as well as a fitns of the second liquid-permeable topsheet to the crotch zone, it is apprehended that a mass of excrements might be squeezed between the wearer's skin and the second liquid-permeable topsheet and the wearer's skin might be smeared over a wide area with excrements thus uncontrollably spread. Should excrements cling to urinary -1fland genital organs, the problem will be serious from the sanitary view point.
Accordingly, it is a principal object of the invention to improve the second liquidpermeable topsheet so that the above-mentioned problems may be effectively overcome even when said second liquid-permeable topsheet is adopted.
SUMMARY OF THE INVENTION The object set forth above is achieved, in accordance with the invention, by a disposable diaper including a first liquid-permeable topsheet, a liquid-impermeable backsheet and a liquid-absorbent panel sandwiched between these sheets to form a laminated structure and additionally including a second liquid-permeable topsheet having a stretchability in length and overlying said first liquid-permeable topsheet and bonded at its longitudinally opposite ends to said laminated structure, wherein said second liquid-permeable topsheet being made of a sheet being S stretchable in width as well as in length; said bonding being performed as said second liquid-permeable topsheet is being stretched both in length and width; and said second S liquid-permeable topsheet being provided with openings at locations corresponding to 0 the wearer's urinary organs and anus, said openings being independent from each other, and with a portion between said openings to provide a barrier to prevent excrements from flowing toward said urinary organs.
While the second liquid-permeable topsheet is put in contact with the wearer's skin over the crotch zone, one of said openings are properly aligned with the urinary .as*.
as" organs and the anus, respectively, so that discharged urine and excrements may flow through the respective openings into a space defined between the second liquidpermeable topsheet and the first liquid-permeable topsheet underlying said second liquid-permeable topsheet.
The second liquid-permeable topsheet is preferably made of a nonwoven fabric.
BRIEF DESCRIPTION OF THE DRAWINGS The invention will be described more in detail by way of example with reference to the accompanying drawings, in which: Fig. 1 is a sketch showing an embodiment of a diaper constructed according to 1, the invention as erected: MC A 39IT DOC Fig. 2 is a developed plan view showing, as partially broken, said diaper; and Fig. 3 is a sectional view taken along a line X-X in Fig. 2, showing said diaper as being curved.
DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to Figs. 1 and 2, a basic diaper structure comprises a first liquidpermeable topsheet 1, a liquid-impermeable backsheet 2, a liquid-absorbent panel 3 sandwiched between said top- and back-sheets 1, 2, elastic members 4, 5 provided between said top- and back-sheets 1, 0 00 00 0 U 0 0* 0 *0 0 00r 0 .00.

I1 UAAAIII qTDOC 2 along the laterally opposite sides and along the rear body's waist, respectively, and fasteners 6 connected to the laterally opposite ends of the rear body's waist.
A second liquid-permeable topsheet 7 is laid on the first liquid-permeable topsheet 1 and bonded at its longitudinally opposite ends to the first liquid-permeable topsheet 1 and the liquid-impermeable backsheet 2 as indicated by an oblique broken lines area in Fig. The second topsheet 7 is stretchable both in length and width and bonded to the basic diaper structure as said second topsheet 7 is being stretched both in length and width so that the second topsheet 7 has an actual width appropriately narrower than the width of the first topsheet 1. The second topsheet 7 is provided at locations Scorresponding to the wearer's urinary organs and anus with openings 8, 9 when the diaper is put on the wearer so dimensioned that urine and excrements discharged from the 4khra "aLok respective organs may pass the respective openings 8, 9 without smearing the top surface of the second topsheet 7.
These openings 8, 9 are independent from each other leaving a portion 10 therebetween. Though not shown, an elastic member may be provided contractibly at the lateral center of the portion 10, that is, between of the openings 8, 9.
The second topsheet 7 has an elongating stress adjusted to 50 to 500g/inch and the panel 3 has a bending -4resistance adjusted to 5 to 20ggcm as measured according to the Taber method. With a consequence, the first and second topsheets 1, 7 are spaced from each other at the maximum preferably by 10mm or more when the diaper is curved under the elongating stress of the second topsheet 7 as shown by Fig. 3.
The topsheets 1, 7 may be made of any nonwoven fabric, the backsheet 2 may be made of any suitable plastic film and the panel 3 may be made of any suitable fluff pulp mixed with superabsorbent polymer.
With the disposable diaper of the invention, as has been described above, the second liquid-permeable topsheet 7 is provided with a pair of the openings 8, 9 adapted to be aligned with urinary organs and anus, respectively, as the second liquid-permeable topsheet 7 closely contacts the wearer's skin over the crotch zone so that urine and excrements discharged from the respective organs may flow through the respective openings 8, 9 directly into the space defined between the second liquid-permeable topsheet 7 and the first liquid-permeable topsheet 1. Accordingly, there is no apprehension that the wearer's skin might be smeared with excrements having been squeezed between the wearer's skin and the second liquid-permeable topsheet 7 and spread. Particularly, the portion 10 of the second liquid-permeable topsheet 7 interposed between the openings 8, 9 and closely contacting the wearer's skin advantageously functions as a barrier to prevent excrements from flowing toward and clinging to the urinary and genital organs.
