Abstract

Claims (44)

1 . A sanitary article comprising:

a topsheet;

a backsheet; and

an absorbent core arranged between the topsheet and the backsheet,

wherein the sanitary article extends in a longitudinal direction and in a transverse direction,

wherein the sanitary article has first and second longitudinal side edges extending in the longitudinal direction and front and rear transverse side edges extending in the transverse direction,

wherein the sanitary article is divided in a front portion, a crotch portion and a rear portion along the longitudinal direction,

wherein the absorbent core comprises a head portion, a body portion, and a neck portion,

wherein the neck portion forms a transitional region between the head portion and the body portion,

wherein the head portion is positioned in the front portion of the sanitary article and the body portion is positioned in the crotch portion and in the rear portion of the sanitary article,

wherein a transverse width of the absorbent core at the neck portion is smaller than a maximum transverse width of the absorbent core in the head portion and in the body portion,

wherein the absorbent core in the front portion of the sanitary article is provided with a shaping element, promoting folding or shaping of the sanitary article,

wherein the shaping element is at least one of a compressed groove, a channel, or a low density region,

wherein the shaping element comprises a rearmost point along the longitudinal direction of the sanitary article,

wherein the sanitary article has a first fastening wing extending along the first longitudinal side edge between a first wing front junction and a first wing rear junction and a second fastening wing extending along the second longitudinal side edge between a second wing front junction and a second wing rear junction,

wherein the first fastening wing has a first adhesive region on a garment facing side thereof,

wherein the second fastening wing has a second adhesive region on a garment facing side thereof,

wherein each of the first adhesive region and the second adhesive region has a respective frontmost border along the longitudinal direction and a respective rearmost border along the longitudinal direction,

wherein the sanitary article has a flat unfolded configuration in which the first and second fastening wings are unfolded and extend outwardly of a respective side of the absorbent core,

wherein, in the flat unfolded configuration, the rearmost point of the shaping element is arranged in an area of the absorbent core extending between a transverse extension of the frontmost border of the first adhesive region and/or the second adhesive region along the longitudinal direction to a maximum width portion of the head portion, and

wherein the absorbent core has no shaping element between the rearmost point of the shaping element and a transverse extension of the rearmost border of the first adhesive region and/or the second adhesive region along the longitudinal direction.

2 . The sanitary article according to claim 1 , wherein a portion of the shaping element coincides with the neck portion of the absorbent core along the longitudinal direction, or is arranged not more than 15 mm from the neck portion, as measured in the longitudinal direction.

3 . The sanitary article according to claim 1 , wherein the first wing front junction and/or the second wing front junction are/is aligned with the neck portion of the absorbent core along the longitudinal direction, or are/is arranged not more than 15 mm rearwardly from the neck portion as measured in the longitudinal direction.

4 . The sanitary article according to claim 1 , wherein the shaping element has a V-shaped section pointing towards the transverse front edge of the sanitary article and/or a V-shaped section pointing towards the transverse rear edge of the sanitary article and/or a first and a second compressed or low-density region arranged along a respective first and second longitudinal edge region of the absorbent core at the neck portion.

5 . The sanitary article according to claim 1 , wherein the shaping element is either a compressed groove or a channel with a depth corresponding to 50% or more of a no-load thickness of the absorbent core, or a low-density region in which the low-density region has a density corresponding to 50% or less of the density of the absorbent core, the no-load thickness or the density of the absorbent core being measured in an area of the absorbent core adjacent to the shaping element.

6 . The sanitary article according to claim 1 wherein the shaping element extends to a first and a second longitudinal edge region of the absorbent core.

7 . The sanitary article according to claim 1 , wherein the shaping element is symmetrical about a longitudinal centerline of the absorbent core.

8 . The sanitary article according to claim 1 , wherein the first and second fastening wings are asymmetrical with respect to any transverse axis extending in the transverse direction.

9 . The sanitary article according to claim 1 , wherein the first and second fastening wings are asymmetrical with respect to each other as seen along any longitudinal axis extending in the longitudinal direction.

10 . The sanitary article according to claim 8 , wherein each of the first and the second adhesive regions has a respective portion with a greater width and a respective portion with a smaller width, as measured in the transverse direction.

11 . The sanitary article according to claim 10 , wherein the first and the second adhesive region are reverse mirror images of each other.

12 . The sanitary article according to claim 1 , wherein a frontmost point of the shaping element is aligned with the neck portion of the absorbent core along the transverse direction.

13 . The sanitary article according to claim 1 , wherein the body portion of the absorbent core in the rear portion of the sanitary article is divided along a longitudinal centerline of the absorbent core into a first core leg portion and a second core leg portion.

14 . The sanitary article according to claim 1 , wherein the absorbent core is provided with a central low-density area, the central low-density area being arranged in the crotch portion of the sanitary article.

15 . The sanitary article according to claim 1 ,

wherein the absorbent core is provided with a rear shaping element comprising a first leg section and a second leg section,

wherein the first and the second leg sections converge towards a longitudinal centerline of the absorbent core and point towards the transverse rear edge of the sanitary article,

wherein each of the first and the second leg sections has a respective first and second frontmost end point, and

wherein each of the first and the second frontmost end points of the respective first and second leg sections is aligned with or arranged rearwardly of the rearmost borders of the first and the second adhesive regions.

16 . The sanitary article according to claim 1 , wherein a frontmost portion of the shaping element overlaps the neck portion.

17 . The sanitary article according to claim 1 , wherein one of the first adhesive region and the second adhesive region does not overlap the shaping element in the transverse direction.

18 . The sanitary article according to claim 1 , wherein both the first adhesive region and the second adhesive region do not overlap the shaping element in the transverse direction.

19 . The sanitary article according to claim 1 , wherein a frontmost portion of the first adhesive region is forward of a frontmost portion of the second adhesive region.

20 . The sanitary article according to claim 1 , wherein the shaping element has a V-shaped section pointing towards the transverse front edge of the sanitary article.
