Abstract

Fibrous structures having two or more zones, sanitary tissue products comprising such fibrous structures, and method for making such fibrous structures and/or sanitary tissue products are provided.

First claim

What is claimed is:

1. A fibrous structure comprising a surface comprising:
a. a first zone defined by one or more portions of a continuous unified design feature occupying at least a first part of the surface's surface area; and
b. a second zone defined by at least a first portion of the remaining part of the surface's surface area not occupied by the first zone;
wherein a visually discernible boundary exists between the first zone and the second zone;
wherein the continuous unified design feature comprises one or more continuous unified design feature embossments at least one of which is selected from the group consisting of: continuous unified design feature line element embossments, continuous unified design feature dot element embossments, and mixtures thereof.

2. The fibrous structure according to claim 1 wherein at least one of the one or more continuous unified design feature embossments comprises at least one continuous unified design feature line element embossments.

3. The fibrous structure according to claim 2 wherein the at least one continuous unified design feature line element embossment defines a boundary between the first zone and the second zone.

4. The fibrous structure according to claim 1 wherein at least 10% of the surface's surface area covered by the continuous unified design feature is void of discrete dot element embossments.

5. The fibrous structure according to claim 1 wherein the first zone comprises one or more brand insignia.

6. The fibrous structure according to claim 1 wherein the second zone comprises one or more first discontinuous unified design features.

7. The fibrous structure according to claim 6 wherein at least one of the first discontinuous unified design features comprises one or more first discontinuous unified design feature embossments.

8. The fibrous structure according to claim 7 wherein at least one of the first discontinuous unified design features comprises two or more first discontinuous unified design feature embossments.

9. The fibrous structure according to claim 8 wherein the at least one of the first discontinuous unified design features comprises three of more first discontinuous unified design feature embossments.

10. The fibrous structure according to claim 6 wherein at least one of the first discontinuous unified design feature embossments is selected from the group consisting of: first discontinuous unified design feature line element embossments, first discontinuous unified design feature dot element embossments, and mixtures thereof.

11. The fibrous structure according to claim 6 wherein at least one first discontinuous unified design feature is separated from its closest adjacent first discontinuous unified design feature by a distance of at least 0.1″ to less than 4″.

12. The fibrous structure according to claim 1 wherein the second zone further comprises a brand insignia.

13. The fibrous structure according to claim 1 wherein the first zone and second zone occupy different parts of the surface's surface area along the fibrous structure's length.

14. The fibrous structure according to claim 1 wherein the first zone is further defined by at least a second portion of the continuous unified design feature occupying a second part of the surface's surface area different from the first part.

15. A single- or multi-ply sanitary tissue product comprising a fibrous structure according to claim 1 .

16. A roll of sanitary tissue product comprising a single- or multi-ply sanitary tissue product according to claim 15 .

17. A package comprising one or more rolls of sanitary tissue product according to claim 15 .

18. The package according to 17 wherein the package comprises a material selected from the group consisting of: film, paperboard, cardboard, compostable materials, biodegradable materials, and mixtures thereof.
