Abstract

An undergarment is conveniently made with two elasticized top panels bonded and cut at a 45 degree angle on a bottom panel. The top panels have curved leg cutouts matched to the curved leg cutouts of the bottom panel. The curved leg cutouts are preferentially cut for the front and back sections of the garment to produce a comfortable fit.

Claims

1. An undergarment of nonwoven fabric comprising:

a. a bottom panel composed of a first web with a longitudinal axis and having left and right curved leg cutouts;

b. a top right panel composed of a second web with a longitudinal axis and having a curved leg cutout, the top right panel curved leg cutout being a compound curve with a first shallow radius curved portion and a second curved portion with a lesser radius than the first curved portion;

c. a top left panel composed of a third web with a longitudinal axis and having a curved leg cutout, the top left panel curved leg cutout being a compound curve with a first shallow radius curved portion and a second curved portion with a lesser radius than the first curved portion; and

d. the top left panel and the top right panel being superimposed on the bottom panel and joined to the bottom panel with seams at angles to the longitudinal axes of the webs, and

e. the bottom panel curved leg cutouts each being a compound curve with a first shallow radius curved portion and a second curved portion with a lesser radius than the first curved portion.

2. The undergarment of nonwoven fabric of claim 1 wherein the angle of the seams is 45 degrees.

3. The undergarment of nonwoven fabric of claim 2 wherein the top right and top left panels are made from highly elastic material.

4. The undergarment of nonwoven fabric of claim 2 wherein the top right and left panels have a highly elastic material placed thereon forming leg elastics at margins of the curved leg cutouts.

5. The undergarment of nonwoven fabric of claim 4 wherein the bottom panel comprises an inner liner layer, a medial absorbent layer, and an outer hydrophobic cover layer.

6. The undergarment of nonwoven fabric of claim 5 wherein the bottom panel further has elastic portions at margins of the leg cutouts.

7. The undergarment of nonwoven fabric of claim 6 wherein the leg cutouts of the top panels are aligned at their edges with the leg cutouts of the bottom panel.

8. The undergarment of nonwoven fabric of claim 1 wherein the top right and top left panels are made from a highly elastic material.

9. The undergarment of nonwoven fabric of claim 1 wherein the top right and left panels have a highly elastic material placed thereon forming leg elastics at margins of the curved leg cutouts.

10. The undergarment of nonwoven fabric of claim 1 wherein the bottom panel comprises an inner liner layer, a medial absorbent layer, and an outer hydrophobic cover layer.

11. The undergarment of nonwoven fabric of claim 1 wherein the bottom panel further has elastic portions at margins of the leg cutouts.

12. The undergarment of nonwoven fabric of claim 1 wherein the leg cutouts of the top panels are aligned at their edges with the leg cutouts of the bottom panel.
