Abstract

Embossed tissue products having improved strength and softness are disclosed. The products as described have a continuous curvilinear emboss element which carries discrete emboss elements, thereby providing the product with the softness and handfeel benefits associated with the long linear elements, but the visual appearance of discrete emboss elements.

First claim

What is claimed is:

1. An embossed roll of paper product comprising:
at least two base sheets comprising an emboss pattern, the emboss pattern comprising:
at least one continuous linear or curvilinear emboss element having a long dimension and a short dimension;
the at least one continuous linear or curvilinear emboss element having a base and a top, wherein the height of the at least one continuous linear or curvilinear emboss element is measured from the base to the top, and the length and width are measured across the base in the long dimension and the short dimension, respectively;
a set of discontinuous emboss elements that project upward from the top of the at least one continuous linear or curvilinear emboss element, wherein the length and width of the discontinuous emboss elements do not exceed the width and length dimension of the at least one continuous linear or curvilinear emboss element and
wherein the at least two base sheets are bonded to one another along the top of a plurality of the discontinuous emboss elements along at least one of the continuous linear or curvilinear emboss elements.

2. The paper roll of claim 1 , wherein the discontinuous emboss elements in the set are dots or dashes.

3. The paper roll of claim 1 , wherein the discontinuous emboss elements in the set are dashes and have an aspect ratio of at least 1.1.

4. The paper roll of claim 1 , wherein the at least one continuous linear or curvilinear emboss element and the discontinuous emboss elements have coextensive side walls.

5. The paper roll of claim 1 , wherein the discontinuous emboss elements in the set are separated by a series of debossments.

6. The paper roll of claim 5 , wherein the series of debossments have a height of from about 0.004 to about 0.025 inches.

7. The paper roll of claim 1 , wherein the at least one base sheet is formed via a non-compactive drying method to achieve a structured sheet.

8. The paper roll of claim 1 , wherein the ratio between the depth of emboss of the at least one continuous linear or curvilinear emboss element and the average depth of the emboss of the set of discontinuous emboss elements is from about 2 to about 5.
