Disposable Absorbent Undergarment Assembly
20180325746 · 2018-11-15 ·

A disposable absorbent undergarment assembly includes briefs that include a front panel and a rear panel attached along lateral edges and a bottom edge to form a waist opening and a pair of leg openings. Each of the lateral edges has a break therein extending through each of the waist opening an adjacent one of the leg openings. Closures are used for selectively opening or closing each break. An absorbent area is defined in a central area of the front and rear panels. An elastic band forms a continuous loop that is free of any breaks. The elastic band has an upper edge and a lower edge. A first mating member is attached to the lower edge and a second mating member is attached to the briefs adjacent to the waist opening. The first and second mating members releasably attach the elastic band to the briefs.

Absorbent article with extensible ears

An absorbent article has a liquid pervious topsheet, a liquid impervious backsheet, an absorbent core disposed between the topsheet and backsheet; first and second opposing longitudinal side edges, a front waist region and a back waist region; and a first and second back ear extending outwardly from the first and longitudinal side edges in the back waist region, respectively. The first and second back ears have an engineering strain greater than about 8% at about or below 2N of force when measured according to the Back Ear Extension Test, and a roughness Ra lower than about 300 ?m when measured according to the Roughness Test.

Composite elastic laminate having discrete film segments

An elastic laminate is provided including outer facing layers of a fabric and, located between the outer facing layers, a series of individual, spaced apart strips of elastic film extending continuously along the direction of elasticity. The film strips are formed by a controlled tearing of a continuous film while the film is biaxially stretched and bonded to the fabric facings. The fabric facings have gathers formed therein that allow the elastic laminate to stretch at least to the extent that the gathers can be pulled flat.
