Garment-like absorbent article
View Patent ↗A garment-like absorbent article includes an absorbent chassis that defines a waist opening and first and second leg openings. A longitudinal length of the chassis is optimized in a linear relationship with the waist circumference of the chassis, the circumference measured at 500 grams tension. With respect to the linear relationship, the thickness of the garment is substantially constant along the same line defined by the length and the circumference, and decreases as the y-intercept increases.

the absorbent chassis having a longitudinal length and the waist opening having a circumference, such that the longitudinal length is proportional to the circumference of the waist opening according to the relation:
Length≦(Circumference+128)/1.6,
wherein the circumference of the waist opening is measured at 500 grams tension, the garment has a thickness of less than about 4.5 millimeters, and a front elastic waist member and a rear elastic waist member are operatively joined to the outer cover, the body side liner, or both.

4. The garment of claim 1 , wherein the garment has a saturated capacity of between about 100 and about 800 grams.
5. The garment of claim 1 , wherein the garment has an edge compression peak load of less than about 1500 grams.
6. A pant-like absorbent garment, comprising:
an absorbent chassis defining a waist opening and first and second leg openings, the absorbent chassis including a bodyside liner, an outer cover that defines an exterior surface of the absorbent garment, and an absorbent assembly enveloped in between the bodyside liner and the outer cover, the bodyside liner, the outer cover and the absorbent assembly being integrally assembled together;
the absorbent chassis having a longitudinal length and the waist opening having a circumference, such that the longitudinal length is proportional to the circumference of the waist opening according to the relation:
Length≦(Circumference+114)/1.6,
wherein the circumference of the waist opening is measured at 500 grams tension, the garment has a thickness of less than about 4.5 millimeters, and a front elastic waist member and a rear elastic waist member are operatively joined to the outer cover, the body side liner, or both.
7. The garment of claim 6 , wherein the garment has a thickness of less than about 3 millimeters.
8. The garment of claim 6 , wherein the circumference of the waist opening is between about 500 and about 700 millimeters.
9. The garment of claim 6 , wherein the garment has a saturated capacity of between about 200 and about 500 grams.
10. The garment of claim 6 , wherein the garment has an edge compression peak load of less than about 1200 grams.
11. A pant-like absorbent garment, comprising:
an absorbent chassis defining a waist opening and first and second leg openings, the absorbent chassis including a bodyside liner, an outer cover that defines an exterior surface of the absorbent garment, and an absorbent assembly enveloped in between the bodyside liner and the outer cover, the bodyside liner, the outer cover and the absorbent assembly being integrally assembled together;
the absorbent chassis having a longitudinal length and the waist opening having a circumference, such that the longitudinal length is proportional to the circumference of the waist opening according to the relation:
Length≦(Circumference+99)/1.6,
wherein the circumference of the waist opening is measured at 500 grams tension, the garment has a thickness of less than about 4.5 millimeters, and a front elastic waist member and a rear elastic waist member are operatively joined to the outer cover, the body side liner, or both.
12. The garment of claim 11 , wherein the garment has a thickness of less than about 2 millimeters.
13. The garment of claim 11 , wherein the circumference of the waist opening is between about 500 and about 700 millimeters.
14. The garment of claim 11 , wherein the garment has a saturated capacity of between about 200 and about 500 grams.
15. The garment of claim 11 , wherein the garment has an edge compression peak load of less than about 800 grams.
16. A process for making a pant-like absorbent garment, comprising:
determining a desired waist circumference for the absorbent garment, measured at 500 grams tension;
determining a desired longitudinal length of the absorbent garment from the following equation:
Length≦(Circumference−b)/m; and
making an absorbent garment having a longitudinal length determined from the equation, the absorbent garment including an absorbent chassis defining the waist circumference and first and second leg openings, the absorbent chassis including a bodyside liner, an outer cover that defines an exterior surface of the absorbent garment, and an absorbent assembly enveloped in between the bodyside liner and the outer cover, the bodyside liner, the outer cover and the absorbent assembly being integrally assembled together, wherein the garment has a thickness of less than about 4.5 millimeters, and wherein a front elastic waist member and a rear elastic waist member are operatively joined to the outer cover, the body side liner, or both.
