Abstract

Disclosed is a sanitary article, including a topsheet, backsheet, acquisition layer and absorbent core arranged between the topsheet, the backsheet and the acquisition layer being arranged between the topsheet and the absorbent core, an extension in a longitudinal direction about a longitudinal centerline and in a transverse direction, a first and a second longitudinal side edge extending in the longitudinal direction and a front and a rear transverse side edge extending in the transverse direction, a frontmost half and in a rearmost half, as seen in the longitudinal direction, the absorbent core including a low-density rear shaping element having a lower density than an adjacent region of the absorbent core, the low-density rear shaping element including shaping element first and second leg sections, the rearmost half of the sanitary article furthermore including a V-shaped or modified V-shaped rear embossed element including first and second embossed leg sections.

Claims (19)

1. A sanitary article, such as a sanitary napkin or a pantiliner, the sanitary article comprising a topsheet, a backsheet, an acquisition layer and an absorbent core, the absorbent core being arranged between the topsheet and the backsheet and the acquisition layer being arranged between the topsheet and the absorbent core, the sanitary article having an extension in a longitudinal direction about a longitudinal centerline and in a transverse direction, the sanitary article having a first and a second longitudinal side edge extending in the longitudinal direction and a front and a rear transverse side edge extending in the transverse direction, the sanitary article being divided in a frontmost half and in a rearmost half, as seen in the longitudinal direction, wherein the absorbent core in the rearmost half of the sanitary article is provided with a low-density rear shaping element having a lower density than an adjacent region of the absorbent core, the low-density rear shaping element comprising a shaping element first leg section and a shaping element second leg section, the rearmost half of the sanitary article furthermore comprising a V-shaped, or modified V-shaped, rear embossed element comprising a first embossed leg section and a second embossed leg section, wherein the shaping element first leg section and the shaping element second leg section tend towards each other and towards the rear transverse side edge of the sanitary article to form a non-intersecting V-shape, the shaping element first leg section and the shaping element second leg section being arranged on a respective side of the longitudinal centerline of the sanitary article, in that the V-shaped rear embossed element is provided only in the topsheet and in the acquisition layer and points towards the rear transverse side edge of the sanitary article and in that the low-density rear shaping element and the V-shaped rear embossed element partly or completely overlap each other.

2. The sanitary article according to claim 1 , wherein the first embossed leg section and the second embossed leg section intersect at a tip portion, the tip portion being aligned with the longitudinal centerline of the sanitary article.

3. The sanitary article according to claim 1 , wherein the absorbent core has a basis weight being at least 20% lower in the low-density rear shaping element than in the adjacent region of the absorbent core.

4. The sanitary article according to claim 1 , wherein the shaping element first leg section and the shaping element second leg section each has a width within the range of from 0.5 mm to 10 mm.

5. The sanitary article according to claim 1 , wherein the first embossed leg section and the second embossed leg section each has a width within the range of from 1 mm to 5 mm.

6. The sanitary article according to claim 1 , wherein the absorbent core has a first and a second longitudinal side edge and wherein the shaping element first leg section extends to the first longitudinal side edge ( 14 ) and the shaping element second leg section extends to the second longitudinal side edge.

7. The sanitary article according to claim 1 , wherein a distance between an inner end point of the shaping element first leg section and an inner end point of the shaping element second leg section is within the range of from 1 mm to 10 mm.

8. The sanitary article according to claim 1 , wherein the absorbent core comprises a head portion, a body portion and a neck portion, the neck portion forming a transitional region between the head portion and the body portion, the head portion being positioned in the frontmost half of the sanitary article and the body portion being positioned in the frontmost half and in the rearmost half of the sanitary article, wherein a transverse width of the absorbent core at the neck region is smaller than a maximum transverse width of the absorbent core in the head portion and in the body portion.

9. The sanitary article according to claim 1 , wherein the absorbent core is provided with a low-density rear central shaping element extending in the longitudinal direction and arranged along the longitudinal centerline of the sanitary article, the low-density rear central shaping element being arranged rearwardly of the low-density rear shaping element.

10. The sanitary article according to claim 9 , wherein the low-density rear central shaping element extends to a rear transverse edge of the absorbent core.

11. The sanitary article according to claim 1 , wherein the sanitary article comprises an embossed crotch functional design element provided only in the topsheet and in the acquisition layer, the embossed crotch functional design element having a boundary comprising a continuous or discontinuous line(s) delimiting an inner crotch region of the embossed crotch functional design element, the embossed crotch functional design element comprising a rear V-shaped section having a tip portion pointing towards the rear transverse side edge of the sanitary article.

12. The sanitary article according to claim 11 , wherein the tip portion of the rear V-shaped section is aligned with and arranged at a distance of from 1 mm to 10 mm from a tip portion of the V-shaped rear embossed element, as seen in the longitudinal direction.

13. The sanitary article according to claim 11 , wherein the embossed crotch functional design element has a first and a second longitudinally extending side section and a front V-shaped section having a tip portion pointing towards the front edge of the sanitary article, and wherein a distance between the first and the second longitudinally extending side sections increases rearwardly, as seen in the longitudinal direction.

14. The sanitary article according to claim 1 , wherein the sanitary article comprises an outer embossed frame pattern provided in the topsheet and in the acquisition layer, following and extending outboard of the periphery of the absorbent core.

15. The sanitary article according to claim 1 , wherein the absorbent core in the frontmost half of the sanitary article is provided with a low-density front shaping element having a lower density than an adjacent region of the absorbent core, the low-density front shaping element comprising a shaping element first leg section and a shaping element second leg section tending towards each other and towards the front transverse side edge of the sanitary article to form a non-intersecting V-shape and wherein the shaping element first leg section and the shaping element second leg section are arranged on a respective side of the longitudinal centerline of the sanitary article.

16. The sanitary article according to claim 15 , wherein the frontmost half of the sanitary article comprises a V-shaped front embossed element comprising a first embossed leg section and a second embossed leg section, and wherein the V-shaped front embossed element is provided only in the topsheet and in the acquisition layer and wherein the low-density front shaping element and the V-shaped front embossed element partly or completely overlap each other.

17. The sanitary article according to claim 16 , wherein the first embossed leg section and the second embossed leg section tend towards each other and towards the front transverse side edge of the sanitary article.

18. The sanitary article according to claim 16 , wherein the first embossed leg section and the second embossed leg section tend towards each other and towards the rear transverse side edge of the sanitary article.

19. The sanitary article according to claim 1 , wherein the absorbent core has a basis weight being at least 40% lower in the low-density rear shaping element than in the adjacent region of the absorbent core.
