Abstract
An absorbent garment, such as a diaper, designed to reduce or eliminate any tendency of the garment to droop when loaded. The absorbent garment includes an absorbent chassis that defines a waist opening and two leg openings. Based on dimensions of the garment, the absorbent chassis suitably has a diaper length ratio of about 0.85 or less, a droop design ratio of about 150 millimeters or less, and/or an absorbent length design ratio of about 280 millimeters or less.
Claims25
An absorbent garment, comprising:
- an absorbent chassis defining a waist opening and first and second leg openings, wherein when in a flat state the absorbent chassis includes opposing curved side edges extending from a back waist region;
- the absorbent chassis having a longitudinal length, wherein the longitudinal length is determined by severing elastic components, in at least a single location, that run the length of the absorbent chassis and suspending the garment with a weight attached thereto, and first and second tabs defining transverse distal edges of the back waist region of the absorbent chassis;
- and
- the absorbent chassis having a diaper length ratio of about 0.85 or less, wherein the diaper length ratio is the longitudinal length of the absorbent chassis divided by an expanded width of the absorbent chassis measured from a distal edge of the first tab to a distal edge of the second tab.

An absorbent garment, comprising:
- an absorbent chassis defining a waist opening and first and second leg openings;
- the absorbent chassis having a longitudinal length, wherein the longitudinal length is determined by severing elastic components, in at least a single location, that run the length of the absorbent chassis and suspending the garment with a weight attached thereto, a crotch region positioned between front and back waist regions of the absorbent chassis, and first and second tabs defining transverse distal edges of the back waist region of the absorbent chassis;
- and
- the absorbent chassis having a droop design ratio of about 150 millimeters or less, wherein the droop design ratio is the longitudinal length of the absorbent chassis multiplied by a width of the crotch region of the absorbent chassis and divided by an expanded width of the absorbent chassis measured from a distal edge of the first tab to a distal edge of the second tab.

An absorbent garment, comprising:
- an absorbent chassis comprising an outer cover, a body side liner, and an absorbent core positioned between the outer cover and the body side liner, the absorbent core defining a waist opening and first and second leg openings;
- the absorbent chassis having a longitudinal length, wherein the longitudinal length is determined by severing elastic components, in at least a single location, that run the length of the absorbent chassis and suspending the garment with a weight attached thereto, a crotch region positioned between front and back waist regions of the absorbent chassis, and first and second tabs defining transverse distal edges of the back waist region of the absorbent chassis;
- and
- the absorbent chassis having an absorbent length design ratio of about 280 millimeters or less, wherein the absorbent length design ratio is the sum of the longitudinal length of the absorbent chassis and a longitudinal length of the absorbent core, multiplied by a width of the crotch region of the absorbent chassis and divided by an expanded width of the absorbent chassis measured from a distal edge of the first tab to a distal edge of the second tab.
