A disposable absorbent article is disclosed having a front portion, a back portion and a crotch portion. The crotch portion joins the front portion to the back portion. The back portion has a first end and a second end. The back portion is divided into a first section and a second section. The first section is extendable in a transverse direction and has a length L2measured perpendicularly from the first end of the back portion to a line drawn parallel thereto. The second section has a length L3measured perpendicularly from the second end of the back portion to the line drawn parallel to the first end. The second section has a first side edge, a second side edge, a first area A1and a second area A2. The first area A, represents an area bounded by the first and second side edges, the second end, and the line drawn parallel to the first end. The second area A2represents an area bounded by first and second lines, the second end, and the line drawn parallel to the first end. The first and second lines are drawn perpendicular to the second end at points where the first and second side edges intersect the second end. The first and second lines intersect the line drawn parallel to the first end. The second section has a ratio A1/A2which ranges from between about 1.3 to about 3.5. First and second fasteners are secured to the back portion. An absorbent is secured to at least one of the front, back or crotch portions. Each of the first and second fasteners are releasably attached to the front portion to form a pant-like article having a waist opening and a pair of leg openings.

An article according to claim 1, wherein the connection between the flaps (9, 10) is comprised of a narrow strip (16) of liquid-permeable or liquid-impermeable material. 3. An article according to claim 1, wherein the connection (16; 21; 24) between the flaps (9, 10; 9', 10'; 28, 29) is located longitudinally between a wearer's wetting point in use and a wearer's fecal discharge point in use. 4. An article according to claim 1, wherein the flaps (9, 10; 9', 10', 28, 29) extend longitudinally from a forward part of said front article part (13; 13') to a rear part of said rear article part (14; 14'). 5. An article according to claim 1, wherein the connection (21; 24) between the flaps (9', 10'; 28, 29) is comprised of a piece of material which is attached along opposing edges to the flaps and to the inner casing sheet respectively by means of transverse connection lines (22, 23). 6. An article according to claim 5, wherein said material piece (21; 24) connecting the flaps (9', 10'; 28, 29) extends transversely from one to the other of said longitudinal edges of the flaps connected to the inner casing sheet (8'; 27), such that the material piece (21; 24) will form a barrier between a front and a rear space defined by the flaps and the underlying absorbent body (1'; 25). 7. An article according to claim 1, wherein elastic devices (17, 18; 17', 18'; 32, 33) extend along said free longitudinal edges (11, 12; 11', 12') of the flaps (9, 10; 9', 10'; 28, 29). 8. An article according to claim 7, wherein said elastic devices (17, 18; 17', 18'; 32, 33) are comprised of elastic threads. 9. An article according to claim 1, wherein the connection (16) between the flaps (9, 10) is elastic.
