摘要： The present disclosure relates to a disposable hygiene article having a transverse direction (x), a longitudinal direction (y) and a longitudinal centerline (A) dividing the article into left-hand and right-hand portions (I) and (ii). The article has a front portion (2), a crotch portion (3) and a rear portion (4), and comprises a liquid-permeable topsheet (30), a liquid-impermeable backsheet (31), and an absorbent core (6) arranged between the topsheet (30) and the backsheet (31). The topsheet (30) and the backsheet (31) extend beyond the absorbent core (6) to provide an outer boundary region (11) of the article that surrounds the absorbent core (6). The outer contour of the absorbent core (6) is defined by mutually symmetrical mirror-imaged portions arranged symmetrically about the longitudinal centre line (A), and defined by left and right core edge lines (8, 9), the core extending between a core front edge (7) in the front portion (2) and a core rear edge (10) in the rear portion (4). The core (6) comprises a neck region (13) at which a transverse width (M) between the left and right core edge lines (8, 9) is smaller than a transverse width of the core (6) forward of the neck region (13), and a transverse width rearward of the neck region (13). The portion of the core forward of the neck region (13) is defined as a head region (14) of the core (6) and the portion of the core rearward of the neck is defined as the body portion (15). The article further comprises at least one asymmetrical wing as seen along any transverse axis, the asymmetrical wing comprising an outer edge (38) extending in an outward direction from the outer periphery (18) of the disposable hygiene article, and wherein the at least one asymmetrical wing outer edge (38) meets the outer periphery of the disposable hygiene article at front (19, 20) and rear wing 25 junctions (21, 22) connected via a wing junction line Jw. The outer edge (38) of said at least one asymmetrical wing comprises a front wing distance point Df and a rear wing distance point Dr, wherein the wing distance point is spaced from the junction line Jw in an outboard transverse direction by a transverse distance J1 of 3 mm. The absorbent core (6) further comprises a first and a second front conforming line (101, 102), the first front conforming line (101) being arranged symmetrically with the second front conforming lines (102) with 47 respect to a longitudinal or a transverse axis. The first front conforming line (101) extends from an outer free end located on or adjacent to the left outer edge (8) towards an inner end located on or adjacent to the longitudinal center line (A) along a first diagonal axis CL1 extending in the plane of the disposable hygiene article. The second front conforming line (102) extends from an outer free end located on or adjacent to the left or right outer edge (8, 9) towards an inner end located on or adjacent to the longitudinal centerline along a second diagonal axis CL2 extending in the plane of the disposable hygiene article, the first and the second diagonal axis (CL1, CL2) converging at a convergence point C. The first and the second front conforming lines (101, 102) have a smallest transverse distance S between their closest approach, wherein the transverse distance S is ≥ 0 mm.

摘要： The present disclosure relates to a disposable hygiene article that comprises an absorbent core arranged between a topsheet and a backsheet. The topsheet and the backsheet provide an outer boundary region of the article that surrounds the absorbent core. The outer contour of the absorbent core is symmetrical about the longitudinal centreline. The core comprises a neck region at which a transverse width between the left and right core edge lines is smaller than a transverse width of the core forward of the neck region, and a transverse width rearward of the neck region. The article further comprises at least one asymmetrical wing as seen along any transverse axis, the asymmetrical wing comprising an outer edge extending in an outward direction from the outer periphery of the disposable hygiene article, and wherein the at least one asymmetrical wing outer edge meets the outer periphery of the disposable hygiene article at front and rear wing junctions connected via a wing junction line Jw. The outer edge of said at least one asymmetrical wing comprises a front wing distance point Df and a rear wing distance point Dr, wherein the wing distance point is spaced from the junction line Jw in an outboard transverse direction by a transverse distance J1 of 3 mm. The front wing distance point Df is spaced from the neck in a rearward longitudinal direction by a first longitudinal distance D1 of between 5-30 mm.
