Publication number: 20220047432Abstract: The present disclosure relates to absorbent articles having an absorbent core that can comprise a laminate longitudinally folded such that the absorbent core includes a lower laminate layer and, within each of first and second longitudinally-extending edge regions, one or more folded laminate layers. A center region of the lower layer can be bonded to a chassis and can span a lateral distance smaller than the width of the absorbent core such that at least a portion of the absorbent core in each of the edge regions is configured to lift away from the chassis. The present absorbent cores can thus define a containment zone to reduce liquid and/or feces leakage.Type: ApplicationFiled: December 3, 2019Publication date: February 17, 2022Applicant: ATTENDS HEALTHCARE PRODUCTS, INC.Inventors: Harry CHMIELEWSKI, Charles F.

Publication number: 20200179184Abstract: This disclosure includes embodiments of disposable absorbent articles and methods of making disposable absorbent articles that include closures with a web of material and hook fasteners that are unitary with the web. For example, some of the present disposable absorbent articles include diapers or briefs with closure members, such as back ears or front ears, defined at least in part by a nonwoven web with hook fasteners that are unitary with the nonwoven web. Use of such unitary hook fasteners allows simpler construction of such articles and/or softer closure members for improved fit and user comfort, and/or other benefits. Certain embodiments of the present methods can manufacture such absorbent articles with fewer manufacturing steps or processes and/or fewer raw materials, relative to those required to manufacture prior art absorbent articles with hook fastener patches that are added by application of a separate piece of material that includes the hook fasteners.Type: ApplicationFiled: July 20, 2018Publication date: June 11, 2020Applicant: ATTENDS HEALTHCARE PRODUCTS, INC.Inventors: Thomas A.
