  • Patent number: 12059877
    Abstract: This disclosure includes ice packs (10) that comprise paper and absorbent material (22A, 22), and also includes various methods of adding liquid to, freezing, shipping, and/or using such ice packs (10). Some of the ice packs (10) of this disclosure have a body (14) that includes first and second layers (54, 58) of paper and one or more side panels (66A) coupled thereto such that the body (14) is expandable. The absorbent material (22A, 22) of some of the ice packs (10) of this disclosure comprises a laminate having an inner layer (70A, 70B, 70C, 70) of superabsorbent polymer disposed between first and second outer layers (78), where the first outer layer (74) comprises tissue and the second outer layer (78) comprises at least one of a tissue and a carded nonwoven.

  • Publication number: 20220047432
    Abstract: 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.

  • Publication number: 20220023110
    Abstract: This disclosure includes absorbent articles comprising first and second absorbent cuffs to prevent leaks. The present articles can comprise a chassis having opposing front and rear portions and a crotch portion extending longitudinally between the front and rear portions. An absorbent core can extend longitudinally along the crotch portion, and the first and second absorbent cuffs can extend longitudinally along the crotch portion as well. The absorbent cuffs can be positioned such that at least a portion of the absorbent core is positioned between the absorbent cuffs, and each can comprise a liftable portion and one or more elastics configured to urge the liftable portion away from the chassis and toward a wearer when the absorbent article is worn. Absorbent or hydrophobic end caps can extend across the ends of the absorbent cuffs.

  • Publication number: 20200179184
    Abstract: 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.
