Benefits of technology

[0007] The present invention is generally directed to nonwoven products, such as nonwoven materials containing pulp fibers, and / or synthetic polymeric fibers, that are provided with a distinctive visual cue or patterned indicia which indicates that the product contains a particular additive, such as a chemical ingredient. The present inventors have discovered that a particular pattern provides benefits and advantages in comparison to various other patterns. The pattern of the present invention includes a burst-like design or pattern that conveys to a user that the product contains a particular additive and differentiates the product from other competitor products. The pattern of the present invention has been found to be well suited for indicating the presence of an additive in a nonwoven product while at the same time using a minimal amount of ink or dye in constructing the pattern.

Problems solved by technology

Nevertheless, tissues having additional special ingredients, such as lotions, virucides, encapsulated scents, and the like do not normally have a visually distinctive appearance that differentiates them from other products.
In particular, although the use of printed indicia to indicate that a tissue product contains unique ingredients is effective for its purpose, the present inventors have realized that printing relatively large amounts of ink onto a product can adversely interfere with the overall aesthetics of the product.
Specifically, some users of a tissue product can perceive ink as a contaminant and therefore less desirable.
Inks may also increase the stiffness of base sheets and can create odor issues.

example

[0063] The following example was performed in order to characterize the burst-like pattern of the present invention in comparison to other patterns.

[0064] Specifically, various patterns were dilated or “grown” after the pattern elements had been subjected to an “ultimate skeleton” processing step. During the ultimate skeleton processing step, the pattern elements are reduced to either a single pixel point or to a single pixel line, depending upon the pattern that is being analyzed. For example, FIG. 4 represents the ultimate skeleton of the pattern shown in FIG. 1. As dilation from a skeletonized starting point occurred, a plot was created of the resulting surface area percent coverage versus dilation step. After results were obtained, a second-order polynomial was determined from the plot. This second-order polynomial was then used to characterize the pattern and provide a point of comparison between different patterns.

Abstract

A sheet-like product is disclosed having a patterned indicia for signifying the existence of an additive or ingredient that is contained within the product. The present inventors have discovered that a particular burst-like pattern provides various advantages and benefits in comparison to other patterns. In order to differentiate patterns of the present invention from other patterns, patterns made according to present invention were image analyzed during a dilation process.

Description

RELATED APPLICATIONS [0001] The present application is a continuation-in-part application of U.S. patent application Ser. No. 10 / 325,469, filed on Dec. 19, 2002.BACKGROUND OF THE INVENTION [0002] Many wiping products, such as standard tissues, are normally white or of a uniform color. In some instances, such as for example, paper towels, decorative patterns may be printed on the outside of the product to enhance its appeal to the consumer. Nevertheless, tissues having additional special ingredients, such as lotions, virucides, encapsulated scents, and the like do not normally have a visually distinctive appearance that differentiates them from other products. Instead, they are typically white, colored or printed just like other wiping products and rely on their packaging to convey to the consumer that they have distinctive properties or characteristics. [0003] In order to make tissues containing special ingredients visually distinguishable from other tissues, a multi-ply tissue havi...
