Publication number: 20180318148Abstract: A feminine care absorbent article (e.g., feminine care pad, sanitary napkin, incontinence article, pantiliner, etc.) that employs a color changing indicator graphic for signaling to the wearer an appropriate time to remove and/or replace the feminine care absorbent article following a liquid insult. This can be particularly useful in warm environments in which a wearer may secrete a significant amount of perspiration which may act as a carrier for microorganisms. In this manner, the wearer can wear the article without fear of a bacterial infection and/or the generation of an odor. After a time period of usage, the wearer can visually inspect the color of the color changing indicator graphic for an indication of whether it is time to remove and/or replace the feminine care absorbent article.Type: ApplicationFiled: November 30, 2015Publication date: November 8, 2018Inventors: Vishal Y.

Publication number: 20150283852Abstract: A cushioning wheel member has an annular body, an axis and multiple cushioning spokes. The annular body has a through hole defined axially through the annular body. The axis is mounted axially and located centrally in the through hole of the annular body. The cushioning spokes are curved and resilient, are deformed to decentralize the axis with external force applied to the cushioning spokes and recover to centralize the axis with removal of the external force. Each cushioning spoke has two ends, and one end of the cushioning spoke is connected to an inner annular surface of the annular body and the other end is connected to the axis. The cushioning spokes are structurally simple and light and may be deformed when encountering external force or impact and therefore provide excellent press-engaging effect and cushioning effect when installed in an ink ribbon cassette and a light duty carrier.Type: ApplicationFiled: March 18, 2015Publication date: October 8, 2015Inventors: Chung-Hsin Chen, Yu-Jung Chen
