Disposable absorbent article with elasticized side panels, and method of making the same

摘要

A disposable absorbent article has a central body that includes an absorbent core, a front longitudinal edge, and a rear longitudinal edge opposite the front longitudinal edge. The disposable absorbent article also has a pair of elasticized side panels that extend longitudinally adjacent opposite lateral sides of the central body. Each side panel has a front longitudinal edge and a rear longitudinal edge opposite the front longitudinal edge, and a front or rear fastening element positioned adjacent the front or rear edge. The front edge of the side panel is positioned closer to the front waist portion than the rear edge. The fastening element is constructed for fastening the front and rear waist portions of the central body when the disposable absorbent article is worn by a user.

主权项

1. A disposable absorbent article disposed in a generally flat, open condition, the disposable absorbent article comprising:
an absorbent assembly including a nonwoven liquid-permeable topsheet, a liquid impermeable backsheet, and an absorbent core disposed between the topsheet and backsheet, the absorbent assembly further characterized by a front edge, a rear edge opposite the front edge, an absorbent assembly length defined by a longitudinal distance between the front edge and rear edge and a central body between the front and rear edges about which the absorbent core is disposed, wherein the front and rear edges define front and rear waist portions respectively and the central body is positioned about a longitudinal centerline extending therethrough and across the front and rear edges; a pair of side panels spaced laterally from the central body and extending longitudinally adjacent opposite sides of the absorbent assembly, each side panel having:
a first material layer,a second material layer,an elasticized region defined by at least one elastomeric element disposed between said material layers and fixedly adhered to at least one of said material layers, said elastomeric element defining an elasticized region length,a substantially inelastic landing area having a landing area length and a front edge substantially aligned with the front edge of the absorbent assembly; anda substantially inelastic finger lift area having a finger lift area length and a rear edge that extends beyond the rear edge of the absorbent assembly; andwherein the elasticized region and the at least one elastomeric element are disposed between the landing area and the finger lift area, and the landing area and the finger lift area are longitudinally spaced apart and disposed on opposite ends of the side panel; and wherein the absorbent article is further defined by an absorbent article length comprising the sum of the landing area length, the finger lift area length, and the elasticized region length, the absorbent article length being greater than the absorbent assembly length.
