Abstract

An absorbent article having a void space for receiving bodily exudates comprises a spacer including an opening in communication with the void space and a body for maintaining at least a portion of the void space. The spacer includes an alignment guide which aids in keeping the spacer opening in a desired configuration for receiving and containing bodily exudates.

Claims

1. A wearable article including a spacer and a primary void space for receiving bodily exudates therein, the spacer comprising:

a body having an opening therein providing a passageway to the primary void space, wherein a portion of the opening is maintained when the article is subjected to compressive loading to provide a secondary void space for receiving bodily exudates therein, and

an alignment guide for maintaining the spacer opening in alignment with a point of discharge on the wearer when the wearable article is worn,

the wearable article further comprising at least two layers and the spacer disposed intermediate the at least two layers, and

wherein the spacer further comprises a first end and a second end opposite the first end, and wherein the alignment guide comprises a first end edge and a second end edge opposite the first end edge, a portion of the spacer near the second end is joined to one of the layers of the article, the first end edge of the alignment guide is joined to the first end of the spacer, and the second end edge of the alignment guide is joined to one of the layers.

2. The wearable article as defined in claim 1 wherein the spacer comprises an air filled bladder.

3. A wearable article as defined in claim 1 wherein the alignment guide further comprises a length and wherein a ratio of the alignment guide length to the spacer length ranges from about 0.1 to about 5.

4. A wearable article as defined in claim 1 wherein the alignment guide comprises a separate element joined to the spacer.

5. A wearable article as defined in claim 1 wherein the alignment guide comprises at least two different materials having different physical properties.

6. A wearable article including a spacer and a primary void space for receiving bodily exudates therein, the spacer comprising:

a body having an opening therein providing a passageway to the primary void space, wherein a portion of the opening is maintained when the article is subjected to compressive loading to provide a secondary void space for receiving bodily exudates therein, and

an alignment guide for maintaining the spacer opening in alignment with a point of discharge on the wearer when the wearable article is worn,

the wearable article further comprising;

a backsheet;

a topsheet joined to the backsheet to form the primary void space, the topsheet having an aperture disposed therein in communication with the primary void space; and

an absorbent core disposed intermediate the backsheet and the topsheet,

wherein the spacer is disposed intermediate the topsheet and the absorbent core such that the opening is in register with the aperture, and

wherein the spacer further comprises a first end and a second end opposite the first end and wherein the alignment guide comprises a first end edge and a second end edge opposite the first end edge;

a portion of the spacer near the second end is joined to an underlying layer while the first end of the spacer is joined to the first end edge of the alignment guide;

the second end edge of the alignment guide is joined to the topsheet.

7. A disposable diaper having a first waist region, a second waist region, and a crotch region interposed therebetween, the disposable diaper comprising:

a backsheet;

a primary topsheet joined to the backsheet;

an absorbent core disposed intermediate the backsheet and the primary topsheet;

a secondary topsheet covering at least a portion of the primary topsheet and joined thereto to form a primary void space for receiving fecal matter therein, the secondary topsheet having an aperture disposed therein in communication with the primary void space;

a spacer disposed in the crotch region for maintaining a Z direction separation between the primary topsheet and the secondary topsheet, the spacer comprising a body having an opening therein providing a passageway to the primary void space wherein at least a portion of the opening is maintained when the article is subjected to compressive loading to provide a secondary void space for receiving fecal matter therein; and

an alignment guide for maintaining the spacer opening in alignment with a wearer'"'"'s anus when the disposable diaper is worn.

8. A disposable diaper as defined in claim 7 wherein a portion of the passageway to the primary void space is maintained when the article is subjected to compressive loading.

9. A disposable diaper as defined in claim 7 wherein the spacer further comprises a first end and a second end opposite the first end, and wherein the alignment guide comprises a first end edge and a second end edge opposite the first end edge, a portion of the spacer near the second end is joined to the primary topsheet while the first end of the spacer is joined to the first end edge of the alignment guide;

the second end edge of the alignment guide is joined to the secondary topsheet.

10. The disposable diaper as defined in claim 7 wherein the secondary topsheet comprises a topical adhesive disposed around a portion of the aperture.
