  • Patent number: 9775750
    Abstract: A signal layer for an absorbent article provided to absorb menstrual fluid includes a pattern of capillary channels allowing capillary action such that discharged menstrual fluid that comes across one of the openings in the capillary channels enters into the capillary channels and is retained therein due to the capillary force. The color of the retained menstrual discharge dyes or colors the pattern for signaling purpose, and the pattern is directly or indirectly visible to an observer.

  • Patent number: 9168732
    Abstract: A method of continuously imparting different visually detectable features to a plurality of items using a printing and/or embossing roll is provided. The circumference of the roll differs from the whole number of the item lengths. In a production series, the number of items each having a different visually detectable feature provided before said visually detectable features repeat themselves is greater than the number of items imparted after one full turn of the roll. Also disclosed is a package including a plurality of items each having a visually detectable feature that is different from the visually detectable features of all other items within the package, such that a first item includes a first visually detectable feature, and a second item includes a second visually detectable feature including at least a portion of the first visually detectable pattern element, wherein the first and second visually detectable features are different.
