Abstract

A package comprising an array of at least two substantially parallelepipedal packs, the packs including compressed flexible articles encased in a flexible bag, and a flexible paper covering disposed adjacent the whole of the bottom panel of the array and a substantial part of the side panels of the array corresponding to at least 30 percent of the height of the array. The paper covering is held under tension around the array so as to create a strong and protective outer casing for the array.

Claims

1. A package comprising an array of at least two substantially parallelepipedal packs, said packs comprising compressed flexible articles encased in a flexible bag, said compressed flexible articles having been compressed to between 20 percent and 70 percent of their uncompressed volume in a direction of compression C, said array comprising a top panel, a bottom panel and four side panels, characterised in that a flexible paper covering is disposed adjacent the whole of said bottom panel and a substantial part of said side panels corresponding to at least 30 percent of height H of said array, said paper covering being held under tension around said array so as to create a strong and protective outer casing for said array.

2. A package according to claim 1 wherein said paper covering adjacent said bottom panel comprises four diagonal fold lines and an attachment means to maintain said diagonal lines in a fixed configuration.

3. A package according to claim 1 wherein said paper covering adjacent one of said side panels comprises a seam and an attachment means to maintain said seam in a fixed configuration.

4. A package according to claim 2 wherein said paper covering adjacent one of said side panels comprises a seam and an attachment means to maintain said seam in a fixed configuration.

5. A package according to claim 1 wherein said paper covering adjacent said bottom panel comprises a completely uninterrupted panel.

6. A package according to claim 5 wherein said paper covering adjacent each of said side panels perpendicular to the direction of compression C comprises two fold lines and an attachment means to maintain said fold lines in a fixed configuration.

7. A package according to claim 1 wherein said paper covering comprises paper of a basis weight of less than 200 grams per square meter.

8. A package according to claim 1, wherein said paper covering comprises an unobstructed opening feature in said paper covering adjacent one of said side panels.

9. A package according claim 1, wherein said compressed flexible articles are disposable absorbent diapers, sanitary articles, incontinent pads or briefs, or bandages.

10. A process for producing a package according to claim 1 comprising the following steps:

a) said array of said packs to be packed is supplied on a feed conveyor to a packaging station;

b) said paper covering is pulled off a supply roll;

c) said paper covering is fed to said packaging station;

d) said array is moved along said packaging station transverse to said paper covering and onto a discharge conveyor in such a manner that said bottom panel and said side panels of said array are surrounded with said paper covering;

e) an attachment means for maintaining said paper covering in a fixed configuration is applied.

11. A process for producing a package according to claim 10 wherein at least three edges of said array are deformed before said attachment means are applied.

12. A process for producing a package according to claim 1 wherein at least three edges of said array are deformed before said attachment means are applied.

13. A process for producing a package according to claim 2 wherein at least three edges of said array are deformed before said attachment means are applied.

14. A process for producing a package according to claim 3 wherein at least three edges of said array are deformed before said attachment means are applied.

15. A process for producing a package according to claim 11 wherein circumference of said array is reduced by at least 3 percent.

16. A process for producing a package according to claim 12 wherein circumference of said array is reduced by at least 3 percent.

17. A process for producing a package according to claim 13 wherein circumference of said array is reduced by at least 3 percent.

18. A process for producing a package according to claim 14 wherein circumference of said array is reduced by at least 3 percent.
