Abstract
An absorbent article can be configured to adhere to the body of a wearer in the area of the body of the wearer that may need bodily fluids absorbed. The absorbent article can be adhered to the body of the wearer to or around the vulva region of the body. The absorbent article can have an absorbent assembly which has a variable height in the longitudinal direction of the absorbent article.
Claims18
An absorbent article comprising:
- a. a longitudinal direction and a transverse direction;
- b. an anterior region, a posterior region, and a central region positioned between the anterior region and the posterior region;
- c. a first transverse direction end edge and a second transverse direction end edge opposed to the first transverse direction end edge defining part of an article perimeter edge;
- d. a topsheet layer comprising a body facing surface;
- e. a backsheet layer;
- f. an absorbent system positioned between the topsheet layer and the backsheet layer, the absorbent system comprising an absorbent core and a perimeter edge where the topsheet layer covers the entirety of the absorbent core and extends beyond the perimeter edge of the absorbent core;
- g. a depth direction wherein the absorbent system has a variable height in the depth direction in the longitudinal direction;
- h. a pair of lines of weakness in the posterior region which generally form a V-shape;
- i. a body adhesive positioned on a portion of the body facing surface of the topsheet layer, the body adhesive comprising a continuous adhesive region extending through each of the anterior region, the posterior region, and the central region, the continuous adhesive region comprising an interior perimeter which is separated by a spatial distance from the perimeter edge of the absorbent system such that the entirety of the interior perimeter of the continuous adhesive region is disposed between the absorbent system and the article perimeter edge;
- and
- j. a notch extending from the perimeter edge of the absorbent article and in a direction towards a longitudinal axis of the absorbent article, the notch being formed in both the topsheet layer and the backsheet layer and not being formed in the absorbent system, wherein the notch does not extend inward beyond the interior perimeter of the continuous adhesive region of the body adhesive.

- d. a topsheet layer comprising a body facing surface;
- e. a backsheet layer;
- f. an absorbent system positioned between the topsheet layer and the backsheet layer, the absorbent system comprising an absorbent core and a perimeter edge where the topsheet layer covers the entirety of the absorbent core and extends beyond the perimeter edge of the absorbent core;
- g. a depth direction wherein the absorbent system has a variable height in the depth direction in the longitudinal direction;
- h. a pair of lines of weakness in the posterior region which generally form a V-shape;
- and
- i. a body adhesive positioned on a portion of the body facing surface of the topsheet layer, the body adhesive comprising a continuous adhesive region extending through each of the anterior region, the posterior region, and the central region, the continuous adhesive region comprising an interior perimeter which is separated by a spatial distance from the perimeter edge of the absorbent system such that the entirety of the interior perimeter of the continuous adhesive region is disposed between the absorbent system and the article perimeter edge, wherein the spatial distance between the interior perimeter of the continuous adhesive region of the body adhesive and the perimeter edge of the absorbent system is determined based upon the height in the depth direction of the absorbent system, wherein the greater the height in the depth direction of the absorbent system then the greater the spatial distance between the interior perimeter of the continuous adhesive region of the body adhesive of the topsheet and the perimeter edge of the absorbent system.
