Absorbent articles incorporating a wetness sensor for indicating the presence of a body fluid are disclosed. The wetness sensor includes an olfactory signaling device that produces a scent or odor when a body fluid is detected. For instance, in one embodiment, an odorous composition can be contained in a water degradable pouch that releases the odorous composition when contacted with moisture. Once released, the odorous composition can produce a desired scent. In other embodiments, the odorous composition can be encapsulated within a water degradable material or can be coated on a substrate. The scent or odor that is released by the odorous composition can vary depending upon the particular application. The scent, for instance, may be pleasant or unpleasant. In one embodiment, the olfactory signaling device may be used to assist in toilet training a child.

1. An absorbent article comprising: a chassis comprising an outer cover having an interior surface and an exterior surface, the chassis containing an absorbent structure positioned adjacent to the interior surface of the outer cover, the chassis including a crotch region positioned in between a front region and a back region, the front region and the back region defining a waist region therebetween;a malodorous composition contained in the chassis, the malodorous composition being positioned in the chassis so as to contact a liquid absorbed by the absorbent structure, the malodorous composition being configured to emit an olfactory cue when the absorbent article is wetted;wherein the malodorous composition is selected from the group consisting of menthol, an amine, a ketone, an aldehyde, an ester, a sulfurous compound, or mixtures thereof; andwherein the malodorous composition is contained in a pouch that releases the malodorous composition when wetted and the pouch includes a wicking strip configured to allow liquid to flow along the wicking strip into the interior of the pouch. 2. The absorbent article as defined in claim 1, wherein the malodorous composition is encapsulated in a material that releases the malodorous composition when wetted. 3. The absorbent article as defined in claim 1, wherein the pouch is made from a water degradable material. 4. The absorbent article as defined in claim 1, wherein the malodorous composition is only present in the crotch region of the chassis. 5. An absorbent article comprising: a chassis comprising an outer cover having an interior surface and an exterior surface, the chassis containing an absorbent structure positioned adjacent the interior surface of the outer cover, the chassis including a crotch region positioned in between a front region and a back region, the front region and the back region defining a waist region therebetween; anda pouch containing an odorous composition located in the chassis, the pouch being made from a material that degrades when wetted, the pouch being positioned in the chassis so as to contact liquids absorbed into the chassis when the absorbent article is being worn, wherein the pouch further comprises a wicking strip extending from the pouch that allows liquids to be absorbed into an interior of the pouch, and wherein, when wetted, the pouch degrades and the wicking strip dissolves to open the pouch to release the odorous composition causing the odorous compound to release an odor signal sufficient to be sensed by the wearer. 6. The absorbent article as defined in claim 5, wherein the material used to form the pouch comprises a starch. 7. The absorbent article as defined in claim 6, wherein the material used to form the pouch further comprises a plasticizer. 8. The absorbent article as defined in claim 5, wherein the material used to form the pouch comprises gelatin, caseine, pectin, agarose, agar, chitosan, carrageenan, cellulose, a cellulose derivative, polyvinyl alcohol, polyvinylpyrrolidone, povidone, guar gum, poloxamer, polyethylene glycol, polyethylene oxide, polyacrylic acid, an alginate, xanthan gum, a hydrogel, a polyurethane, or mixtures thereof. 9. The absorbent article as defined in claim 7, wherein the material used to form the pouch further comprises a plasticizer. 10. The absorbent article as defined in claim 5, wherein the odorous composition comprises a liquid. 11. The absorbent article as defined in claim 5, wherein the odorous composition comprises a solid. 12. The absorbent article as defined in claim 5, wherein the odorous composition emits a olfactory signal. 13. The absorbent article as defined in claim 12, wherein the odorous composition comprises menthol. 14. The absorbent article as defined in claim 12, wherein the olfactory signal has a vegetable-like scent. 15. The absorbent article as defined in claim 5, wherein the odorous composition comprises an essential oil or an extract. 16. The absorbent article as defined in claim 5, wherein the odor signal comprises a fragrance, the fragrance having a fruit-like smell, a flower-like smell, an herbal-like smell, or a woodland-like smell. 17. The absorbent article as defined in claim 5, wherein the odorous composition has a pleasant smell at low concentrations and an unpleasant smell at higher concentrations. 18. A method for toilet training a child comprising: donning on a child an absorbent article, the absorbent article including a chassis that defines two leg openings opposite a waist opening, the chassis comprising an outer cover having an interior surface and an exterior surface, the chassis further including an absorbent structure positioned adjacent the interior surface of the outer cover, the chassis including a crotch region positioned in between the two leg openings and in between a front region and a back region of the chassis, the absorbent article further containing a malodorous composition that is configured to emit an unpleasant odor when wetted wherein the malodorous compound is selected from the group consisting of menthol or ester;wherein the malodorous composition is contained in a pouch that releases the malodorous composition when wetted and the pouch includes a wicking strip configured to allow liquid to flow along the wicking strip into the interior of the pouch; andinstructing the child to urinate in a toilet as opposed to urinating in the absorbent article and releasing the unpleasant odor. 19. An absorbent article comprising: a chassis comprising an outer cover having an interior surface and an exterior surface, the chassis containing an absorbent structure positioned adjacent to the interior surface of the outer cover, the chassis including a crotch region positioned in between a front region and a back region, the front region and the back region defining a waist region therebetween;a malodorous composition contained in the chassis, the malodorous composition being positioned in the chassis so as to contact a liquid absorbed by the absorbent structure, the malodorous composition being configured to emit an olfactory cue when the absorbent article is wettedwherein the malodorous composition is contained in a pouch that releases the malodorous composition when wetted and the pouch includes a wicking strip configured to allow liquid to flow along the wicking strip into the interior of the pouch; andwherein the olfactory cue emitted by the malodorous composition comprises a vegetable-like scent. 20. A method for toilet training a child comprising: donning on a child an absorbent article, the absorbent article including a chassis that defines two leg openings opposite a waist opening, the chassis comprising an outer cover having an interior surface and an exterior surface, the chassis further including an absorbent structure positioned adjacent the interior surface of the outer cover, the chassis including a crotch region positioned in between the two leg openings and in between a front region and a back region of the chassis, the absorbent article further containing a malodorous composition that is configured to emit an unpleasant vegetable-like or fruit-like scent when wetted;wherein the malodorous composition is contained in a pouch that releases the malodorous composition when wetted and the pouch includes a wickinq strip configured to allow liquid to flow along the wicking strip into the interior of the pouch; andinstructing the child to urinate in a toilet as opposed to urinating in the absorbent article and releasing the unpleasant odor.
