The invention relates to an absorbent, disposable article, preferably a diaper, having a backsheet and a topsheet comprising a first waist region, a second waist region, and a crotch region interposed there between, a longitudinal axis, and an opening, which provides a passageway to a primary void space for receiving bodily exudates therein, positioned between the topsheet and the backsheet, whereby the opening is positioned in at least the crotch region along the longitudinal axis; whereby the topsheet is elasticated; and whereby the article has a shortened article portion, as defined herein, which has a shortened article length L, a stretched shortened article length Ls and a contracted shortened article length Lc, whereby the article and/or its topsheet has an specific elastic profile and/or a specific ratio of Lc to Ls. The article preferably has a slit opening with on each side elastic regions, preferably in the shape of an X, as shown in FIG. 1, and preferably making an angle with the adjacent topsheet and thereby bending away from the void space underneath the topsheet.

What is claimed is: 1. An absorbent article comprising: a backsheet; a topsheet connected with the backsheet and having longitudinally opposing first and second waist regions and a crotch region intermediate the first and second waist regions; a void space between the topsheet and the backsheet for receiving bodily exudates; an opening in the topsheet, positioned in at least the crotch region, and providing access to the void space, the opening having longitudinally extending first and second side edges, and wherein first end portions of the first and second side edges of the opening converge toward each other to define a first end point of the opening in the first waist region, and wherein second end portions of the first and second side edges of the opening converge toward each other to define a second end point of the opening in the second waist region; and wherein the topsheet includes first and second laterally opposing elasticated regions disposed adjacent respective first and second side edges of the opening in the crotch region, the first and second elasticated regions being substantially parallel to each other in the crotch region and laterally diverging from each other in the first and second waist regions and wherein the elasticated regions form an X-shape. 2. The absorbent article of claim 1, wherein the opening comprises a slit. 3. The absorbent article of claim 1, wherein the opening comprises a shape defined by a rectangular portion disposed between two longitudinally opposing triangular portions. 4. The absorbent article of claim 1, wherein the first and second elasticated regions comprise first and second elastic bands. 5. The absorbent article of claim 1, wherein the absorbent article is a disposable diaper and further comprises an absorbent core disposed between the topsheet and the backsheet. 6. The absorbent article of claim 1, further comprising a shortened article portion having a shortened article length L, a stretched shortened article length Ls, and having an elastic profile defined by a two-cycle hysteresis test of: 0.25 Ls by a first load force of less than 0.6 N, 0.55 Ls by a first load force of less than 5 N, and 0.8 Ls by a first load force of less than 10.0 N; and a second unload force at 0.55 Ls of greater than 0.4 N, and a second unload force at 0.80 Ls of greater than 1.4 N. 7. The absorbent article of claim 6, having an elastic profile of: 0.25 Ls by a first load force of less than 0.6 N, 0.55 Ls by a first load force of less than 3.5 N, and 0.8 Ls by a first load force of less than 7.0 N; and a second unload force at 0.55 Ls of greater than 0.4 N, and a second unload force at 0.80 Ls of greater than 2.0 N. 8. The absorbent article of claim 1, further comprising a shortened article portion having a shortened article length L, a stretched shortened article length Ls, the topsheet having a shortened topsheet length Lt, the topsheet having an elastic profile defined by a two-cycle hysteresis test of: 1.5 Lt by a first load force of less than 1.1 N, 3.0 Lt by a first load force of less than 2.1 N, and 4.5 Lt by a first load force of less than 3.0 N; and a second unload force at 4.5 Lt of greater than 0.9 N, a second unload force at 3.0 Lt of greater than 0.5 N, and a second unload force at 1.5 Lt of greater than 0.1 N. 9. The absorbent article of claim 8, the topsheet having an elastic profile of: 1.5 Lt by a first load force of less than 0.6 N, 3.0 Lt by a first load force of 1.1 N, and 4.5 Lt by a first load force of less than 1.5 N; and a second unload force at 4.5 Lt of greater than 0.9 N, a second unload force at 3.0 Lt of greater than 0.5 N and a second unload force at 1.5 Lt of greater than 0.1 N. 10. The absorbent article of claim 1, further comprising a shortened article portion having a shortened article length L, a stretched shortened article length Ls, and a contracted shortened article length Lc, wherein Lc is less than 0.5 Ls. 11. The absorbent article of claim 10, wherein Lc is less than 0.35 Ls. 12. The absorbent article of claim 1, further comprising a shortened article portion having a shortened article length L, a stretched shortened article length Ls, and having an elastic profile defined by a two-cycle hysteresis test wherein: a ratio of a 1st load force at 0.50 Ls to a 2nd unload force at 0.50 Ls is less than 20; a ratio of a 1st force at 0.65 Ls to a 2nd unload force at 0.65 Ls is less than 9; and a ratio of a 1st load force at 0.80 Ls to a 2nd unload force at 0.80 Ls is less than 4. 13. The absorbent article of claim 12, having an elastic profile wherein: a ratio of a 1st load force at 0.50 Ls to a 2nd unload force at 0.50 Ls is less than 7; a ratio of a 1st load force at 0.65 Ls to a 2nd unload force at 0.65 Ls is less than 6; and a ratio of a 1st load force at 0.80 Ls to a 2nd unload force at 0.80 Ls is less than 4. 14. The absorbent article of claim 13, having an elastic profile wherein: a ratio of a 1st load force at 0.50 Ls to a 2nd unload force at 0.50 Ls is less than 3; a ratio of a 1st load force at 0.65 Ls to a 2nd unload force at 0.65 Ls is less than 2; and a ratio of a 1st load force at 0.80 Ls to a 2nd unload force at 0.80 Ls is less than 1.5. 15. An absorbent article comprising: a backsheet; a topsheet connected with the backsheet and having longitudinally opposing first and second waist regions and a crotch region intermediate the first and second waist regions; a means for receiving bodily exudates between the backsheet and the topsheet; a means for providing access to the means for receiving bodily exudates, the means for providing access being located in at least the crotch region and having longitudinally extending first and second side edges, and wherein first end portions of the first and second side edges converge toward each other to define a first end point in the first waist region, and wherein second end portions of the first and second side edges of the opening converge toward each other to define a second end point in the second waist region; a first and second means for elasticating the topsheet disposed adjacent the means for providing access, the first and second means for elasticating being substantially parallel to each other in the crotch region and laterally diverging from each other in the first and second waist regions, thereby forming an X-shape. 16.
