Disposable underpants and method

A disposable underpant defining an initial expanded shape having longitudinal and transverse axes, a front section, a back section, said front section and said back section being oppositely disposed on said longitudinal axis, and a central section disposed between said front section and said back section, each said section having a length along the longitudinal axis of one third of the length of said underpant, comprising:

• a) an outer cover having a front body portion and a back body portion connected by a crotch portion, said front and back body portions being connected together to form a waist opening and two leg openings;
• b) an absorbent barrier composite associated within at least said crotch portion having a liquid impervious layer, a pervious layer, and a rectangular absorbent core having a front end edge and a back end edge positioned between said liquid impervious layer and a pervious layer;
• and
• c) said outer cover further comprising leg elastic positioned around each of said leg openings to form a gather around each said leg opening, and waist portion elastic positioned around said front and back body portions to form gathers of said front and back body portions,
• wherein said absorbent core is positioned within said sections such that the length of said absorbent core in the back section divided by the length of said absorbent core in said front section and said central section is less than 0.10 and said length of said absorbent core in said front section is greater than said length of absorbent core in said back section.

A method of forming a disposable underpant defining an initial expanded shape having longitudinal and transverse axes, a front section, a back section, said front section and said back section being oppositely disposed on said longitudinal axis, and a central section disposed between said front section and said back section, each said section having a length along the longitudinal axis of one third of the length of said underpant, comprising:

• a) providing an outer cover having a front body portion and a back body portion connected by a crotch portion, said front and back body portions connected together to form a waist opening and two leg openings;
• and
• b) providing an absorbent barrier composite associated within at least said crotch portion having a liquid impervious layer, a pervious layer, and a rectangular absorbent core having a front end edge and a back end edge positioned between said liquid impervious layer and a pervious layer,
• wherein said absorbent core is positioned within said sections such that the length of said absorbent core in the back section divided by the length of said absorbent core in said front section and said central section is less than 0.10 and said length of said absorbent core in said front section is greater than said length of absorbent core in said back section.
