Abstract
This invention relates to the discovery that the perceived softness of embossed tissue can be increased greatly while avoiding prior art nesting problems if a particular pattern is embossed into the tissue. This pattern combines relatively shallow stitchlike debossments with deeper more sharply defined signature debossments. The stitchlike debossments are rounded and arranged in wavy flowing intersecting lines. The signature debossments are arranged in regions framed by the intersecting wavy flowing lines.
Claims35
A sheet of tissue having a plurality of debossments formed therein defining a lattice pattern having a plurality of polygonal cells, a fraction, more than one-third but less than two-thirds, of said polygonal cells being filled with a signature debossment, said lattice pattern having generators and being defined by a sinuous array of stitchlike debossments undulating about the generators of said lattice pattern, said stitchlike debossments being encompassed by rotund arcuate regions having cross-sectional radii of curvature exceeding at least about 0.015 inch;
- said signature being comprised of a plurality of elongated debossments having a depth of deboss exceeding the depth of deboss of said stitchlike debossments by at least 0.003 inch, said elongate debossments being encompassed by arcuate regions having cross-sectional radii of curvature of the arcuate regions encompassing said stitchlike debossments.
A roll of embossed tissue having a plurality of debossments formed therein, said debossments comprising:
- two series of intersecting sinuous lines of stitchlike debossments, one series of lines being disposed at a first acute angle clockwise of the machine direction of the roll, the other series of lines being disposed at a second acute angle counterclockwise of the machine direction of the roll whereby a repeating pattern comprising an oblique lattice of substantially uniform staggered wavy diamonds is defined;
- a plurality of signature debosses centrally located within alternating rows of said diamond, the disposition of said debossments being configured such that substantial nesting of said signature embosses on said rolls occurs at a maximum of two locations on said roll, the outermost of said locations being spaced at least 1/32 inch below the exterior surface of said roll and, the innermost, at least 0.5 inch inward from said outermost substantial nesting location.
A roll of embossed tissue having a plurality of debossments formed therein, said debossments comprising:
- two equally spaced series of intersecting sinuous lines of stitchlike debossments, one series of lines being disposed at a first acute angle clockwise of the machine direction of the roll, the other series of lines being disposed at a second acute angle counterclockwise of the machine direction of the roll whereby an oblique lattice of substantially uniform staggered wavy diamonds is defined;
- a plurality of signature debosses centrally located within alternating rows of said diamond, the disposition of said debossments being configured such that, adjacent to the surface of said roll, signature debossments on closely adjacent overlapping repeats are displaced from each other by at least 0.50 inch.
A sheet of tissue having a plurality of debossments formed therein defining a lattice pattern having a plurality of polygonal cells, a fraction, less than all, of said polygonal cells being filled with a signature debossment, said lattice pattern having generators and being defined by a sinuous array of stitchlike debossments undulating about the generators of said lattice pattern, said stitchlike debossments being encompassed by upwardly flaring regions;
- said signature being comprised of a plurality of elongated debossments having a depth of deboss exceeding the depth of deboss of said stitchlike debossments, said elongate debossments being encompassed by upwardly flaring regions encompassing said stitchlike debossments being more steeply inclined than the upwardly flaring regions encompassing said stitchlike debossments.
