An absorbent article comprising:
- a liquid-permeable topsheet;
- a backsheet;
- and
- an absorbent core sandwiched between the topsheet and the backsheet,
- wherein the absorbent article extends in a longitudinal direction (L) and in a transverse direction (T),
- wherein the absorbent article defines a front waist portion, a rear waist portion, a crotch portion arranged between the rear waist portion and the front waist portion as seen in the longitudinal direction (L), and a buttocks portion arranged between the crotch portion and the rear waist portion,
- wherein the topsheet comprises a first lubricant zone provided with a lubricant agent,
- wherein the first lubricant zone is arranged over the buttocks portion,
- wherein the first lubricant zone overlaps a majority of a rear edge of the absorbent core,
- wherein an entire perimeter of the first lubricant zone is bounded by a lubricant agent free zone, and
- wherein an entirety of the first lubricant zone is on a rear side of a longitudinal center of the absorbent article and spaced apart from the longitudinal center.
An absorbent article comprising:
- a liquid-permeable topsheet;
- a backsheet;
- and
- an absorbent core sandwiched between the topsheet and the backsheet,
- wherein the absorbent article extends in a longitudinal direction (L) and in a transverse direction (T),
- wherein the absorbent article defines a front waist portion, a rear waist portion, a crotch portion arranged between the rear waist portion and the front waist portion as seen in the longitudinal direction (L), and a buttocks portion arranged between the crotch portion and the rear waist portion,
- wherein the topsheet comprises a first lubricant zone provided with a lubricant agent,
- wherein the first lubricant zone is arranged over the buttocks portion,
- wherein the absorbent core comprises a first absorbent layer and a second absorbent layer,
- wherein the first absorbent layer has a first absorbent layer front edge and a first absorbent layer rear edge,
- wherein the second absorbent layer has a second absorbent layer front edge and a second absorbent layer rear edge, the absorbent layers each having a size and a shape in a plane of the absorbent article, the size and shape of the second absorbent layer defining the size and shape of the absorbent core in the plane of the absorbent article,
- wherein the first absorbent layer is shorter than the second absorbent layer, as seen in the longitudinal direction (L) of the absorbent article,
- wherein each of the first and the second absorbent layers comprises superabsorbent polymers,
- wherein the first absorbent layer is an upper absorbent layer and the second absorbent layer is a lower absorbent layer,
- wherein the amount of superabsorbent polymer is from 1.6 times higher in the upper absorbent layer than in the lower absorbent layer, and
- wherein the first lubricant zone extends beyond a rear edge of the absorbent core and overlaps a rear elastic portion of the absorbent article.
A belt-type absorbent article,
- wherein the absorbent article is a belted absorbent article comprising an absorbent pad and a separate belt,
- wherein the pad is detachably attached to the separate belt,
- wherein the separate belt is configured to be placed around the waist of the wearer to hold the pad when the article is being worn,
- wherein the absorbent pad comprises:
- a liquid-permeable topsheet,
- a backsheet, and
- an absorbent core sandwiched between the topsheet and the backsheet,
- wherein the absorbent pad extends in a longitudinal direction and in a transverse direction,
- wherein the absorbent pad defines a front waist portion, a rear waist portion, and a crotch portion arranged between the rear waist portion and the front waist portion as seen in the longitudinal direction (L), and a buttocks portion arranged between the crotch portion and the rear waist portion,
- wherein the article in the buttocks portion in a first lubricant zone arranged on the topsheet is provided with a lubricant agent,
- wherein the separate belt is provided with a lubricant agent in a belt lubricant zone,
- wherein the first lubricant zone overlaps a majority of a rear edge of the absorbent core,
- wherein an entire perimeter of the first lubricant zone is bounded by a lubricant agent free zone, and
- wherein an entirety of the first lubricant zone is on a rear side of a longitudinal center of the absorbent article and spaced apart from the longitudinal center.
