Abstract

A tri-folded disposable absorbent article comprising a substantially cellulose free absorbent core located in a chassis between a topsheet and a backsheet and comprising absorbent particulate polymer material. An array of absorbent article packages comprising disposable absorbent articles comprising a substantially cellulose free absorbent core is also disclosed.

Claims

1. A disposable absorbent article comprising:

a chassis including a topsheet and a backsheet; and

a substantially cellulose free absorbent core located between the topsheet and the backsheet and comprising absorbent particulate polymer material,

the disposable absorbent article having a longitudinal axis extending from a first end to a second end and tri-folded substantially perpendicularly to the longitudinal axis along a first fold line and a second fold line spaced from the first fold line so as to form a central section extending from the first fold line to the second fold line, a first end section extending from the first fold line to the first end, and a second end section extending from the second fold line to the second end, so that the first section, central section, and second section are superposed to one another.

2. The disposable absorbent article of claim 1, wherein the first section, central section, and second section are substantially coextensive.

3. The disposable absorbent article of claim 1, wherein the first section overlays the central section and the second section overlays the first section.

4. The disposable absorbent article of claim 1, wherein:

the absorbent core includes first and second absorbent layers, the first absorbent layer including a first substrate and the second absorbent layer including a second substrate;

the absorbent particulate polymer material is deposited on said first and second substrates;

the absorbent core further comprises thermoplastic adhesive material covering the absorbent particulate polymer material on the respective first and second substrates; and

said first and second absorbent layers are combined together such that at least a portion of said thermoplastic adhesive material of said first absorbent layer contacts at least a portion of the thermoplastic adhesive material of said second absorbent layer.

5. The disposable absorbent article of claim 4, wherein the absorbent particulate polymer material is disposed between the first and second substrates in an absorbent particulate polymer material area, and the absorbent particulate polymer material is substantially continuously distributed across the absorbent particulate polymer material area.

6. The disposable absorbent article of claim 5, wherein:

the absorbent particulate polymer material is deposited on the of a second substrates in respective patterns of land areas and junction areas between the land areas such that the absorbent particulate polymer material is discontinuously distributed on the first and second substrates; and

the first and second absorbent layers are combined together such the respective patterns of absorbent particulate polymer material are offset from one another.

7. The disposable absorbent article of claim 5, wherein the absorbent particulate polymer material area extends substantially entirely across the absorbent core.

8. The disposable absorbent article of claim 1, wherein the absorbent core contains less than about 10% by weight cellulosic fibers.

9. The disposable absorbent article of claim 6, wherein the absorbent core has a length extending from a rear end to a front end, and a width extending from a first edge to a second edge and perpendicularly to the length, and the respective patterns are offset from one another in both a direction parallel to the length and a direction parallel to the width.

10. The disposable absorbent article of claim 1, wherein the disposable absorbent article is a diaper or a pant.

11. The disposable absorbent article of claim 1, wherein the disposable absorbent article occupies a volume of less than about 200 cc per absorbent article under base compression of from about 2500 to about 5000 N.

12. An absorbent article package comprising:

a packaging material; and

a plurality of disposable absorbent articles disposed in the packaging material in a substantially superposed stacked configuration, the disposable absorbent articles occupying a volume in the package of less than about 200 cc per absorbent article under base compression of from about 2500 to about 5000 N and the disposable absorbent articles each comprising;

a chassis including a topsheet and a sheet; and

a substantially cellulose free absorbent core located between the topsheet and the backsheet and comprising absorbent particulate polymer material; and

each disposable absorbent article having a longitudinal axis extending from a first end to a second end and tri-folded substantially perpendicularly to the longitudinal axis along a first fold line and a second fold line spaced from the first fold line so as to form a central section extending from the first fold line to the second fold line, a first end section extending from the first fold line to the first end, and a second end section extending from the second fold line to the second end, so that the first section, central section, and second section are superposed to one another.

13. An array of absorbent article packages comprising:

a plurality of absorbent article packages, each of the absorbent article packages comprising a packaging material and a plurality of disposable absorbent articles disposed in the packaging material in a substantially superposed stacked configuration;

the disposable absorbent articles each comprising a chassis including a topsheet and a backsheet and a substantially cellulose free absorbent core located between the topsheet and the backsheet and comprising absorbent particulate polymer material.

14. The array of claim 13, wherein each disposable absorbent article has a longitudinal axis extending from a first end to a second end and is tri-folded substantially perpendicularly to the longitudinal axis along a first fold line and a second fold line spaced from the first fold line so as to form a central section extending from the first fold line to the second fold line, a first end section extending from the first fold line to the first end, and a second end section extending from the second fold line to the second end, so that the first section, central section, and second section are superposed to one another.

15. The array of claim 14, wherein:

at least a first of the plurality of absorbent article packages comprises disposable absorbent articles having a first size and occupying a volume in the at least the first of the plurality of absorbent article packages of less than about 200 cc per absorbent article under base compression of from about 2500 to about 5000 N; and

at least a second of the plurality of absorbent article packages comprises disposable absorbent articles having a second size different than the first size and occupying a volume in the at least the second of the plurality of absorbent article packages different than the volume occupied by the disposable absorbent articles having the first size in the first of the plurality of absorbent article packages.

16. The array of claim 14, wherein the first section, central section, and second section are substantially coextensive.

17. The array of claim 14, wherein the first section overlays the central section and the second section overlays the first section.

18. The array of claim 14, wherein:

the absorbent core includes first and second absorbent layers, the first absorbent layer including a first substrate and the second absorbent layer including a second substrate;

the absorbent particulate polymer material is deposited on said first and second substrates;
