Abstract

A package (1) comprising an array (3) of compressed, flexible absorbent articles (5) that have a front face (7), a back face (9), a top face (6), a bottom face (8), side faces (10), an upper section (11) and a lower section (13). The upper and lower sections have mutually different compressibilities and calipers, and the absorbent articles are placed with the front and back faces in a contacting relationship. The package comprises a flexible outer casing (19). The array has a first region (15) and a second region (17) and the upper and lower sections of the absorbent articles are distributed over the first and second regions of the array in such a manner that the difference in the compression force F for compression of the first and second regions to between 20% and 70% of their uncompressed volume is at least 10% smaller than the difference in the compression force for compression of the first and second regions when all of the upper sections of the absorbent articles are located in the same region of the array.

Claims

1. A package (1) comprising an array (3) of compressed, flexible absorbent articles (5), said absorbent articles (5) comprising a front face (7), a back face (9), a top face (6), a bottom face (8), side faces (10), an upper section (11) and a lower section (13), said sections having mutually different compressibilities and calipers, wherein said absorbent articles are placed with said front and back faces (7, 9) in a contacting relationship, said package (1) comprising a flexible outer casing (19), said array (3) having a first region (15) and a second region (17) and said upper and lower sections (11, 13) of said absorbent articles (5) being distributed over said first and second regions (15, 17) of said array (3), wherein said distribution of upper and lower sections (11, 13) is such that the difference in the compression force F for compression of said first and second regions (15, 17) to between 20% and 70% of their uncompressed volume, is at least 10% smaller than the difference in the compression force for compression of said first and second regions (15, 17) when all of said upper sections (11) of said absorbent articles (5) are located in the same region of said array (3);

and said flexible outer casing (19) maintains said array (3) of compressed articles.

2. A package according to claim 1, wherein the upper and lower sections (11, 13) of the absorbent articles (5) are distributed in such a way that the compression forces for said first and second regions (15, 17) of the array (3) are substantially equal.

3. A package according to claim 1, wherein the orientation of the absorbent articles is altered at intervals.

4. A package according to claim 1, wherein after compression the dimension along the direction of compression of the first region of the array is substantially equal to the dimension along the direction of compression of the second region of the array.

5. A package according to claim 1, wherein after compression the expansion force of the first region is substantially equal to the expansion force of the second region.

6. A package according to claim 1, wherein said absorbent articles comprise different calipers in the upper and lower sections.

7. A package according to claim 1, wherein said package does not comprise on inner means;

to maintain said array of compressed articles.

8. method of forming a package comprising an array of compressed, flexible absorbent articles, said absorbent articles comprising a front face, a back face, a top face, a bottom face, side faces, an upper section and a lower section, said sections having mutually different compressibilities and calipers, wherein said absorbent articles are placed with said front and back faces in a contacting relationship, said package comprising a flexible outer casing, said array having a first region and a second region and said upper and lower sections of said absorbent articles being distributed over said first and second regions of said array, said distribution of upper and lower sections being such that the difference in the compression force F for compression of said first and second regions to between 20% and 70% of their uncompressed volume, is at least 10% smaller than the difference in the compression force for compression of said first and second regions when all of said upper sections of said absorbent articles are located in the same region of said array;

and said flexible outer casing maintaining said array of compressed articles;

said method comprising the following steps;

transporting said absorbent articles in a consecutive manner to a folding unit,

folding said absorbent articles,

changing the orientation of said absorbent articles at regularly spaced intervals,

aligning a predetermined number of said absorbent articles with said front and back faces in a contacting relationship to form an uncompressed array, wherein a predetermined number of said absorbent articles have their said upper sections located in a first region of said array and a second predetermined number of said absorbent articles have their

said upper sections located in a second region of said array,

compressing said array, and

placing the compressed array in a flexible outer casing.

9. A method according to claim 8, wherein the compression force F is substantially uniform across said first and second regions.
