Abstract
Absorbent articles comprising odor control compositions that are not visible from the outside of the article due to placement on or next to the absorbent core wrap.
Claims20
A disposable absorbent article comprising a longitudinal centerline and a lateral centerline, a front waist region with a front waist edge, a rear waist region with a rear waist edge, a crotch region disposed between the front and rear waist regions, and two spaced apart longitudinal side edges joining the front waist edge to the rear waist edge, comprising:
- a) a topsheet;
- b) a backsheet;
- c) an absorbent core disposed between the topsheet and the backsheet, the absorbent core comprising a core wrap;
- and
- d) a liquid management system disposed between the topsheet and the absorbent core, the liquid management system comprising a distribution layer, wherein the distribution layer comprises a distribution layer surface area that faces the core wrap;
- wherein an odor control composition is directly joined to a core wrap surface area facing the liquid management system;
- wherein the core wrap surface area facing the liquid management system comprises a continuous surface free of apertures;
- wherein the distribution layer surface area is less than the core wrap surface area;
- and
- wherein the odor control composition is disposed only on a portion of the core wrap surface area that is overlapped by the distribution layer.
A disposable absorbent article comprising a longitudinal centerline and a lateral centerline, a front waist region with a front waist edge, a rear waist region with a rear waist edge, a crotch region disposed between the front and rear waist regions, two spaced apart longitudinal side edges joining the front waist edge to the rear waist edge, and comprising:
- a) a topsheet;
- b) a backsheet;
- c) an absorbent core disposed between the topsheet and the backsheet, wherein the absorbent core comprises a nonwoven core wrap, and wherein the absorbent core comprises less than about 2% by weight of absorbent material contained within the core wrap of cellulose;
- and
- d) a liquid management system disposed between the topsheet and the absorbent core, the liquid management system comprising a distribution layer, wherein the distribution layer comprises a distribution layer surface area that faces the core wrap;
- wherein activated carbon, zeolite, and/or silica are directly joined to a topsheet-facing surface of the core wrap;
- wherein the topsheet-facing surface of the core wrap comprises a continuous surface free of apertures;
- wherein the distribution layer surface area is less than the core wrap surface area;
- and
- wherein the activated carbon, zeolite, and/or silica are disposed only on a portion of the core wrap surface area that is overlapped by the distribution layer.
A disposable absorbent article comprising a longitudinal centerline and a lateral centerline, a front waist region with a front waist edge, a rear waist region with a rear waist edge, a crotch region disposed between the front and rear waist regions, two spaced apart longitudinal side edges joining the front waist edge to the rear waist edge, and comprising:
- a) a topsheet;
- b) a backsheet;
- c) an absorbent core disposed between the topsheet and the backsheet, wherein the absorbent core comprises a nonwoven core wrap;
- d) a liquid management system disposed between the topsheet and the absorbent core, the liquid management system comprising an acquisition layer and a distribution layer;
- and
- e) an odor control composition comprising activated carbon, zeolites, silica, or combinations thereof;
- wherein the odor control composition is disposed between the acquisition and distribution layers;
- and
- wherein a topsheet-facing surface of the core wrap comprises a continuous surface free of apertures.
