Patent number: 10716718Abstract: An absorbent article that has a reduced tendency to shift when worn. The absorbent article includes a chassis with a front waist portion, a crotch portion, and a back waist portion. Side panels or ears are attached to the front and back waist portions of the chassis, and fastening components are attached to the back ears. Anti-skid elements are added to the outside surface and/or inside surface of the front side panels or ears and/or to the inside surface of the fastening tabs, such as by applying an elastomeric strip in a substantially vertical direction. When the absorbent article is fastened to the wearer attaching the fastening components on the back ears to the front waist portion of the absorbent article, the anti-skid elements interface with the front waist portion, the front ears, and/or the wearer to exert friction and thereby reduce shifting of the fastened absorbent article.Type: GrantFiled: June 24, 2016Date of Patent: July 21, 2020Assignee: FIRST QUALITY BABY PRODUCTS, LLCInventors: Susan O'Connell, Carol L.

Publication number: 20040064113Abstract: This invention relates to the field of absorbent articles in general, and more particularly to absorbent articles that have wetness/dryness indicators disposed thereon. Preferably, the disposable absorbent article, for example, a training pant, includes a disappearing wetness/dryness indicator that disappears when the article is wetted, and an appearing wetness/dryness indicator that appears when the article is wetted. The wetness/dryness indicators preferably allow a caregiver to interact with a child to promote toilet training. The wetness/dryness indicators are graphic elements that may or may not be related to one another, and that may or may not be related to other graphic elements on the article.Type: ApplicationFiled: September 26, 2002Publication date: April 1, 2004Inventor: Carol L.
