Abstract
Abstract A method for making a breathable elastomeric laminar fabric, the material produced thereby and a disposable absorbent garment incorporating the material as either an outer cover or gathers at the leg and waist openings. The method comprises the steps of sandwiching a liquid impermeable elastomeric film or nonwoven carrier sheet between a pair of nonwoven facing sheets while the carrier sheet is in at least a partially stretched condition and bonding the facing sheets together through the carrier sheet at spaced apart sites, simultaneously forming breathable apertures while laminating the carrier and facing sheets together at the spaced apart sites. Creped facing sheets may also be used and bonded together while the film is in a partially stretched or unstretched condition.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
135 words
A disposable absorbent garment comprising: an outer cover including a pair of leg openings, front and rear waist sections defining a waist opening, inner and outer surfaces, a central crotch portion between said leg openings and opposed front and rear panels separated by said crotch portion; an absorbent structure superposable on said outer cover, for absorbing and retaining bodily exudates; gathers at either of said leg opening and said waist opening; and wherein either of said leg and waist gathers are formed from a breathable elastomeric nonwoven laminar fabric comprising a liquid impervious elastomeric film carrier sheet sandwiched and bonded at spaced apart sites between two or more nonwoven facing sheets thereby forming air permeable apertures therein at said bond sites, providing a cushioned cloth-like fit of said garment about the body of a wearer.
Claim 2
Dependent Claim
135 words
A disposable absorbent garment comprising: an outer cover including a pair of leg openings, front and rear waist sections defining a waist opening, inner and outer surfaces, a central crotch portion between said leg openings and opposed front and rear panels separated by said crotch portion; an absorbent structure superposable on said outer cover, for absorbing and retaining bodily exudates; gathers at either of said leg opening and said waist opening; and wherein either of said leg and waist gathers are formed from a breathable elastomeric nonwoven laminar fabric comprising a liquid impervious elastomeric film carrier sheet sandwiched and bonded at spaced apart sites between two or more nonwoven facing sheets thereby forming air permeable apertures therein at said bond sites, providing a cushioned cloth-like fit of said garment about the body of a wearer.
Claim 3
Dependent Claim
131 words
A disposable absorbent garment comprising: an outer cover including a pair of leg openings, front and rear waist sections defining a waist opening, inner and outer surfaces, a central crotch portion between said leg openings and opposed front and rear panels separated by said crotch portion; an absorbent structure superposable on said outer cover, for absorbing and retaining bodily exudates; gathers at either of said leg openings and said waist openings; and wherein said outer cover is formed from a breathable elastomeric nonwoven laminar fabric comprising a liquid impervious elastomeric film carrier sheet sandwiched and bonded at spaced apart sites between two or more nonwoven facing sheets thereby forming air permeable apertures therein at said bond sites, providing a cushioned cloth-like fit of said garment about the body of a wearer.
Claim 4
Dependent Claim
131 words
A disposable absorbent garment comprising: an outer cover including a pair of leg openings, front and rear waist sections defining a waist opening, inner and outer surfaces, a central crotch portion between said leg openings and opposed front and rear panels separated by said crotch portion; an absorbent structure superposable on said outer cover, for absorbing and retaining bodily exudates; gathers at either of said leg openings and said waist openings; and wherein said outer cover is formed from a breathable elastomeric nonwoven laminar fabric comprising a liquid impervious elastomeric film carrier sheet sandwiched and bonded at spaced apart sites between two or more nonwoven facing sheets thereby forming air permeable apertures therein at said bond sites, providing a cushioned cloth-like fit of said garment about the body of a wearer.
