Abstract
Abstract A disposable absorbent article such as a diaper (10), is disclosed. The diaper has two lengthwise extending longitudinal marginal portions (50), each longitudinal marginal portion having two elastically extensible leg cuffs, a barrier cuff (62) and a gasket cuff (56). The leg cuffs (56,62) serve to help contain body exudates within the disposable article. Each leg cuff (56,62) is elasticized to provide a relatively low ultimate contact force against the skin of the wearer at relatively high elongations. This arrangement provides a diaper with leg cuffs which can be elongated to conform to the shape of the wearer, without causing undue discomfort or irritation to the legs of the wearer. The relatively low ultimate contact force at relatively high elongations may be accomplished either through a low contact force differential material, or through a material which exhibits stress relaxation over a relatively short period of time.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
127 words
A disposable absorbent article having two transverse waist portions and two longitudinal marginal portions, said article comprising: a liquid impervious backsheet; a liquid pervious topsheet at least partially peripherally joined to said backsheet; an absorbent core intermediate said topsheet and said backsheet; and at least one leg cuff disposed in each longitudinal marginal portion, each said leg cuff having at least one elastic member defining a cumulative width, wherein said leg cuff is elastically extensible in at least one direction and elongated about 50 to about 350 percent, without rupture, upon application of about 270 grams per centimeter of said cumulative width and said leg cuff has a differential force per 50 percent increment of elongation less than about 14 grams per centimeter of said cumulative width.
Claim 2
Dependent Claim
127 words
A disposable absorbent article having two transverse waist portions and two longitudinal marginal portions, said article comprising: a liquid impervious backsheet; a liquid pervious topsheet at least partially peripherally joined to said backsheet; an absorbent core intermediate said topsheet and said backsheet; and at least one leg cuff disposed in each longitudinal marginal portion, each said leg cuff having at least one elastic member defining a cumulative width, wherein said leg cuff is elastically extensible in at least one direction and elongated about 50 to about 350 percent, without rupture, upon application of about 270 grams per centimeter of said cumulative width and said leg cuff has a differential force per 50 percent increment of elongation less than about 14 grams per centimeter of said cumulative width.
Claim 3
Dependent Claim
141 words
A disposable absorbent article having two transverse waist portions and two longitudinal marginal portions, said article comprising: a liquid impervious backsheet; a liquid pervious topsheet at least partially peripherally joined to said backsheet; an absorbent core intermediate said topsheet and said backsheet; and at least one leg cuff disposed in each longitudinal marginal portion, each said leg cuff having at least one elastic member defining a cumulative width, wherein said leg cuff is elastically extensible in at least one direction and elongated about 50 to about 350 percent, without rupture, upon application of about 270 grams per centimeter of said cumulative width after at least about 10 minutes at a temperature of at least about 22°C and said leg cuff has a differential force per 50 percent increment of elongation less than about 14 grams per centimeter of said cumulative width.
