The present disclosure relates to a disposable absorbent chassis (10) having a liquid-pervious topsheet (1), a backsheet (3), and a liquid absorbent core (2) disposed between the liquid-pervious topsheet and the backsheet. The chassis has a pair of longitudinal elasticized standing leg gathers (4, 5) and a pair of elasticized outer leg barriers (30a, 30b) disposed on either side of the longitudinal central axis. Each of the elasticized outer leg barriers (30a, 30b) comprises a substrate folded inward (34) toward the longitudinal central axis, a distal folded edge (31) and a substrate edge (303b, 304b) that is transversely inward from the distal folded edge, such that a folded portion (33) extends between the distal folded edge (31) and the substrate edge (303b, 304b). An elastic member (8a) is disposed within the folded portion at the distal folded edge of the elasticized outer leg barriers (30a, 30b), and each of the elasticized outer leg barriers (30a, 30b) is bonded to one of the lateral flaps (50a, 50b) of the longitudinal elasticized standing leg gathers (4, 5).
A disposable absorbent chassis (10) having a longitudinal direction along a longitudinal central axis (Y-Y), a transverse direction along a transverse central axis (X-X), a user-facing side and a garment-facing side, a front waist portion (11), a rear waist portion (13) and a crotch portion (12) disposed longitudinally between the front waist portion (11) and the rear waist portion (13);
A disposable absorbent chassis (10) having a longitudinal direction along a longitudinal central axis (Y-Y), a transverse direction along a transverse central axis (X-X), a user-facing side and a garment-facing side, a front waist portion (11), a rear waist portion (13) and a crotch portion (12) disposed longitudinally between the front waist portion (11) and the rear waist portion (13);
A disposable absorbent chassis according to any of the preceding claims, characterized in that the elasticized outer leg barriers (30a, 30b) comprise a portion of the liquid impervious film layer (3a).
A disposable absorbent chassis according to any of the preceding claims, characterized in that the liquid impervious film layer width is narrower than the outer cover layer width.
A disposable absorbent chassis according to any of the preceding claims, characterized in that the substrate of the elasticized outer leg barriers (30a, 30b) has one or both of:
A disposable absorbent chassis according to any of the preceding claims, characterized in that the lateral flaps (50a, 50b) of the longitudinal elasticized standing leg gathers (4, 5), has one or both of:
A disposable absorbent chassis according to any of the preceding claims, characterized in that each of the elasticized outer leg barriers (30a, 30b) comprises two or more elastic members.
A disposable absorbent chassis according to any of the preceding claims, characterized in that the bonding (90) of each of the elasticized outer leg barriers (30a, 30b) to one of the lateral flaps (50a, 50b) of the longitudinal elasticized standing leg gathers (4, 5) is done by heat sealing, ultrasonic bonding, thermal bonding, by adhesives, or by stitching, and/or extends over the full surface of attachment or is present in stripes, in dots or any adequate pattern ensuring appropriate joining or bonding between the outer leg barriers (30a, 30b) and the lateral flaps (50a, 50b) of the elasticized longitudinal standing gathers (4, 5), as well as adequate bonding between the proximal portion (6a, 6b) of the longitudinal elasticized standing leg gather (4,5) and the topsheet (1).
A disposable absorbent diaper (100) including a disposable absorbent chassis according to any of the preceding claims, wherein said disposable absorbent diaper includes a pair of opposed back ear panels (20a, 20b) joined to the longitudinal side edges (16, 17) of the chassis (10) at the back waist portion (13) and a pair of opposed frontal ears joined to the longitudinal side edges (16,17) of the chassis (10) in the front portion (11), characterized in that the at least one elastic member (8a) of the elasticized outer leg barriers (30a, 30b) extends between the back ear panels (20a, 20b) and the front ear panels (60a, 60b).
