Abstract

The present disclosure provides a packaging unit for hygiene articles and a method for forming such a unit. The packaging unit has a first packaging function as a packaging wrap for a non-used article, and a second disposal function as a disposal wrap for a used article. The packaging unit further comprises a user prompting device having a wrap-facing surface and a user-facing surface, wherein the user prompting device is permanently attached to the wrap such that at least a portion of the wrap-facing surface of the user prompting device is in contact with the inner surface of the wrap. The user prompting device is arranged to prompt the user to employ the second disposal function of the packaging unit.

First claim

The invention claimed is:

1. A packaging unit for hygiene articles, comprising a wrap formed from a sheet of material, said wrap having an inner and an outer surface, said inner surface comprising an edge zone comprising an inner edge portion and an outer edge portion, said wrap having at least one folding axis, said at least one folding axis dividing said wrap into a first region and a second region, wherein one of said inner edge portion and said outer edge portion of said edge zone of said first region is provided with a first resealable adhesive, and the other of said inner edge portion and said outer edge portion of said edge zone of said first region is adhesive-free; wherein one of said inner edge portion and said outer edge portion of said edge zone of said second region is provided with said first resealable adhesive, and the other of said inner edge portion and said outer edge portion of said edge zone of said second region is adhesive-free in a complementary manner to said edge zone of said first region, such that when said wrap is folded about said at least one folding axis, said one of the inner edge portion and the outer edge portion carrying said first resealable adhesive in said first region is brought in contact with said one of the inner edge portion and the outer edge portion that is adhesive-free in said second region, and said one of the inner edge portion and the outer edge portion carrying said first resealable adhesive in said second region is brought in contact with said one of the inner edge portion and the outer edge portion that is adhesive-free in said first region, said packaging unit configured to have a first packaging function as a packaging wrap for a non-used article, and a second disposal function as a disposal wrap for a used article, wherein said packaging unit further comprises a user prompting device having a wrap-facing surface and a user-facing surface, wherein said user prompting device is permanently attached to said wrap such that at least a portion of said wrap-facing surface of said user prompting device is in contact with said inner surface of said wrap, and said user prompting device is configured to prompt the user to employ said second disposal function, wherein said user prompting device comprises user prompting means being visible and legible from said user-facing surface of said user prompting device.

2. The packaging unit according to claim 1 , wherein said user prompting means is printed on at least one of the user-facing surface of said user prompting device and the wrap-facing surface of said user prompting device.

3. The packaging unit according to claim 1 , wherein said user prompting device is opaque.

4. The packaging unit according to claim 1 , wherein said user prompting device comprises a release liner.

5. The packaging unit according to claim 4 , wherein said release liner is manufactured from one of paper, non-woven and plastic film material.

6. The packaging unit according to claim 1 , wherein said user prompting device is silicone-coated on said user-facing surface of said user prompting device.

7. A packaging unit according to claim 1 , wherein a longitudinal extension of said user prompting device is 60-100% of a longitudinal extension of said wrap.

8. A packaging unit according to claim 1 , wherein said sheet of material is of substantially rectangular shape and comprises longitudinal edges, transverse edges and corner portions, said edge zone of said first region and said edge zone of said second region of said sheet of material being arranged along said longitudinal edges.

9. The packaging unit according to claim 8 , wherein said sheet of material comprises transverse edge zones and wherein at least a portion of at least one of said transverse edge zones is provided with said first resealable adhesive.

10. The packaging unit according to claim 8 , wherein a portion of a transverse edge zone of said first region is provided with said first resealable adhesive, and a remaining portion of said transverse edge zone of said first region is adhesive-free, and a portion of a transverse edge zone of said second region is provided with said first resealable adhesive, and a remaining portion of said transverse edge zone of said second region is adhesive-free in a complementary manner to said transverse edge zone of said first region such that when said sheet of material is folded about said at least one folding axis, said transverse edge zone carrying said first resealable adhesive in said first region is brought in contact with said adhesive-free transverse edge zone in said second region, and said transverse edge zone carrying said first resealable adhesive in said second region is brought in contact with said adhesive-free transverse edge zone in said first region.

11. The packaging unit according to claim 8 , wherein at least one of said corner portions is free from said first resealable adhesive such that a gripping tab is formed.

12. The packaging unit according to claim 8 , wherein said sheet of material has two folding axes dividing said sheet of material into said first region, said second region and a third region.

13. The packaging unit according to claim 12 , wherein said sheet of material is folded along said two folding axes with said first region, said second region and said third region in an overlapping configuration.

14. The packaging unit according to claim 12 , wherein an edge portion of an edge zone of said third region is provided with said first resealable adhesive corresponding to the edge portion of said edge zone of said first region provided with said first resealable adhesive, and is complementary to the edge portion of said edge zone of said second region provided with said first resealable adhesive, such that a chessboard pattern of said first resealable adhesive is formed along each of said longitudinal edges.

15. The packaging unit according to claim 14 , wherein a width of the edge portions of two adjacent ones of the first region, the second region and the third region that are provided with the first resealable adhesive is dimidiated compared to a width of the remaining one of the first region, the second region and the third region that are provided with the first resealable adhesive.

16. The packaging unit according to claim 12 , wherein at least a portion of one of said transverse edge zones is provided with said first resealable adhesive.

17. The packaging unit according to claim 1 , wherein said wrap is at least one of being opaque and comprising print.

18. The packaging unit according to claim 1 , wherein said first resealable adhesive is a pressure-sensitive adhesive with unlimited open time.

19. A packaged disposable hygiene article comprising:
a packaging unit according to claim 1 ; and
a hygiene article releasably affixed to said user prompting device.

20. A method of forming a packaging unit for hygiene articles from a sheet of material, said packaging unit configured to have a first packaging function as a packaging wrap for a non-used article, and a second disposal function as a disposal wrap for a used article, said method comprising the steps of:
a. providing a sheet having an inner surface and an outer surface, said inner surface comprising an edge zone comprising an inner edge portion and an outer edge portion, said sheet having a first folding axis, said first folding axis dividing said sheet into a first region and a second region, wherein said first region comprises a first central portion, and said second region comprises
