Claim 18:
19. A disposable absorbent pant, having a longitudinal axis (y), a lateral axis (x), a front waist region, a rear waist region and a crotch region between the front and rear waist regions, the pant comprising:
a central chassis extends from the front waist region through the crotch region to the rear waist region and comprises a topsheet, a backsheet and an absorbent core placed in between the topsheet and the backsheet, the central chassis having a laterally extending chassis front edge, a laterally extending chassis rear edge and first and second longitudinally extending chassis side edges;
an elasticized front belt provided in the front waist region and an elasticized rear belt provided in the rear waist region, the front and rear belt each having a body-facing surface and a garment-facing surface, the front belt having a transversally extending front waist edge, the rear belt having a transversally extending rear waist edge, the front and rear belt each having a first and second longitudinally extending side edge, with the first side edge of the front belt being joined to the first side edge of the rear belt and the second side edge of the front belt being joined to the second side edge of the rear belt at side seams to form a waist opening and two leg openings;
the absorbent core comprising an absorbent layer, the absorbent layer having a laterally extending front edge, a laterally extending rear edge and first and second longitudinally extending side edges, the absorbent layer comprising a continuous channel formed therein, the continuous channel having a first and a second longitudinally-oriented elongate portion and a third and fourth laterally-oriented elongate portion;
the first portion being provided between the longitudinal axis (y) and the first side edge of the absorbent layer, the second portion being provided between the longitudinal axis (y) and the second side edge of the absorbent layer;
the first and second portion each having a front end towards the absorbent layer's front edge, a rear end towards the absorbent layer's rear edge and a center which is equally spaced from the front and rear ends across the longitudinal axis (y), each of the first and second portion being curved such that the first portion is closer to the longitudinal axis (y) at a necking point than the front and rear end of the first portion, and such that the second portion is closer to the longitudinal axis (y) at a necking point than the front and rear end of the second portion;
the first and second portion being spaced apart from each other at their necking point by a first distance L1, wherein the distance L1 is from 20 mm to 50 mm;
the third portion connecting the front end of the first portion with the front end of the second portion and extending from the front end of the first portion to the front end of the second portion;
the fourth portion connecting the rear end of the first portion with the rear end of the second portion and extending from the rear end of the first portion to the rear end of the second portion;
the absorbent layer having a first transverse width W1 extending from the first longitudinally extending side edge to the second longitudinally extending side edge across the necking point of the first and second portion;
the first and second portion being spaced apart from each other at their rear ends by a second distance L2, the absorbent layer having a second transverse width W2 extending from the first longitudinally extending side edge to the second longitudinally extending side edge across the rear ends of the first and second portion;
the first and second portion being spaced apart from each other at their front ends by a third distance L3;
the third distance L3 between the front end of the first portion and front end of the second portion being larger than the distance between any two points located on the third portion;
the second distance L2 between the rear end of the first portion and the rear end of the second portion being larger than the distance between any two points located on the fourth portion;
the second and third distances L2 and L3 each being larger than the distance between any two points located on the first and second portion between the front and rear ends of the first and second portion;
wherein the ratio of W2 to L2 is from 1.5 to 2.8;
wherein the ratio of W1 to L1 is higher than the ratio of W2 to L2; and
wherein the ratio of L2 to L1 is from 1.2 to 2.5; and
wherein the first portion follows a first curved path with only one curve between the necking point and the rear end of the first portion, and the first portion follows a second curved path with only one curve between the necking point and the front end of the first portion, wherein the first curved path of the first portion has a steeper curvature compared to the second curved path of the first portion; and
wherein the second portion follows a first curved path with only one curve between the necking point and the rear end of the second portion, and the second portion follows a second curved path with only one curve between the necking point and the front end of the second portion, wherein the first curved path of the second portion has a steeper curvature compared to the second curved path of the second portion.
