## Abstract

Disclosed is a wearable article continuous in a longitudinal direction and a transverse direction comprising a center chassis and a ring-like elastic belt comprising a front belt and a back belt; the front and back belt each formed by a laminate comprising a plurality of elastic bodies running in the transverse direction, an inner sheet, an outer sheet, and an outer sheet fold over; wherein at least one of the front belt and the back belt has: a) the longitudinal edge of the center chassis being distal than, preferably at least about 10 mm distal than, the outer sheet fold over proximal edge; b) in the left and right side panels: b-1) at least one elastic body, preferably at least two elastic bodies, disposed between the outer sheet and the outer sheet fold over in regions where the inner sheet does not overlap; b-2) one to no more than about 8 elastic bodies disposed between the outer sheet and inner sheet in regions where the outer sheet fold over overlaps in the thickness direction, and b-3) the remaining elastic bodies disposed between the outer sheet and the inner sheet in regions where the outer sheet fold over does not overlap in the thickness direction, wherein any elastic body disposed between the outer sheet and the inner sheet is disposed at least about 5 mm away from the inner sheet distal edge.

## Claims

### Claim 1

A wearable article continuous in a longitudinal direction and a transverse direction, comprising:
a center chassis and a ring-like elastic belt comprising a front belt and a back belt;
the center of the front belt is joined to a front waist panel of the center chassis, the center of the back belt is joined to a back waist panel of the center chassis, and the remainder of the center chassis is a crotch panel, the front and back belt each having a left side panel and a right side panel where the center chassis does not overlap, and the transverse edges of the front belt and the back belt are joined by a seam to form a waist opening and two leg openings; wherein the front belt and back belt are discontinuous of each other in the longitudinal direction;
the front and back belt each formed by a laminate comprising a plurality of elastic bodies running in the transverse direction, an inner sheet, an outer sheet, and an outer sheet fold-over, the outer sheet fold-over being an extension of the outer sheet material formed by folding the outer sheet material toward the body facing side at distal edges of the front and back belts, the outer sheet fold-over directly joined to the center chassis; and
wherein at least one of the front belt and the back belt has:
a) a longitudinal edge of the center chassis being distal an outer sheet fold-over proximal edge such that the outer sheet fold-over overlaps the center chassis;
b) in the left and right side panels:
b-1) at least one elastic body disposed between the outer sheet and the outer sheet fold-over in regions where the inner sheet is not present;
b-2) one to no more than 8 elastic bodies disposed between the outer sheet and inner sheet in regions where the outer sheet fold-over overlaps both the outer sheet and the inner sheet, and
b-3) the remaining elastic bodies disposed between the outer sheet and the inner sheet in regions where the outer sheet fold-over is not present, wherein any elastic body disposed between the outer sheet and the inner sheet is disposed at least about 5 mm away from an inner sheet distal edge.

### Claim 2 (depends on 1)

The article of claim 1, wherein the inner sheet and the outer sheet are different in at least one of basis weight, stiffness, and texture.

### Claim 3 (depends on 1)

The article of claim 1, wherein the center chassis comprises an absorbent material existing region and an absorbent material non-existing region, the non-existing region disposed along the longitudinal edges of the center chassis, wherein at least some of the elastic bodies overlapping the existing region is deactivated of its elasticity in at least certain of the length the elastic body overlaps the existing region.

### Claim 4 (depends on 3)

The article of claim 3, wherein at least one elastic body overlapping the non-existing region is disposed in active elasticity.

### Claim 5

The article of any of the preceding claims wherein the longitudinal edge of the center chassis is from about 10 mm to about 90 mm away from the belt distal edge.

### Claim 6 (depends on 1)

The article of claim 1, wherein the longitudinal distance D1 between the front belt distal edge and the longitudinal edge of the center chassis on the front side is smaller than the longitudinal distance D2 between the back belt distal edge and the longitudinal edge of the center chassis on the back side, preferably the difference between D1 and D2 is from about 15 mm to about 40 mm.

### Claim 7 (depends on 1)

The article of claim 1, wherein both the front belt and the back belt have at least one elastic body disposed between the outer sheet and the outer sheet fold-over in regions where the inner sheet is not present.

### Claim 8 (depends on 1)

The article of claim 1, wherein the center chassis comprises an outer cover layer at the most garment facing side and a backsheet attached to the body facing surface of the outer cover layer; wherein the longitudinal length of the outer cover layer is longer than the longitudinal length of the crotch panel and shorter than the longitudinal length of the backsheet, the area on the front waist panel or the back waist panel where the outer cover layer is present forming a transitional region.
