Abstract
Absorbent articles comprising elastic waist members and methods of manufactured are disclosed. In an embodiment, an absorbent article may comprise a chassis including an absorbent body and a body facing surface. The article may further comprise a first adhesive disposed on the body facing surface of the chassis and an elasticated waist member coupled to the body facing surface of the chassis by the first adhesive. The article may still further comprise a second adhesive disposed on the elasticated waist member and a waist region covering material coupled to the elasticated waist member by the second adhesive.
Claims20
An absorbent article including a front waist region including a front waist edge, a rear waist region including a rear waist edge, a crotch region disposed between the front waist region and the rear waist region, a longitudinal axis extending in a longitudinal direction and a lateral axis extending in a lateral direction, the absorbent article comprising:
- a chassis including an absorbent body, the chassis including a body facing surface;
- a first adhesive disposed on the body facing surface of the chassis;
- an elasticated waist member coupled to the body facing surface of the chassis by the first adhesive;
- a second adhesive disposed on the elasticated waist member;
- and
- a waist region covering material coupled to the elasticated waist member by the second adhesive.
An absorbent article including a front waist region including a front waist edge, a rear waist region including a rear waist edge, a crotch region disposed between the front waist region and the rear waist region, a longitudinal axis extending in a longitudinal direction and a lateral axis extending in a lateral direction, the absorbent article comprising:
- a chassis including an absorbent body, the chassis including a body facing surface;
- a first adhesive disposed on the body facing surface of the chassis in the rear waist region;
- an elasticated waist member coupled to the body facing surface of the chassis in the rear waist region by the first adhesive;
- a first waist region covering material coupled to the body facing surface of the chassis and disposed entirely in the rear waist region, the first waist region covering material covering at least a portion of the elasticated waist member and having a lateral top edge and a lateral bottom edge, the lateral top edge being disposed closer to the rear waist edge than the lateral bottom edge;
- and
- a second waist region covering material coupled to the body facing surface of the chassis and disposed entirely in the front waist region and having a lateral top edge and a lateral bottom edge, the lateral top edge being disposed closer to the crotch region than the lateral bottom edge, the first waist region covering material and the second waist region covering material being formed of a same material,
- wherein the lateral top edge of the first waist region covering material is disposed at approximately the same longitudinal position as the rear waist edge such that the lateral top edge and the rear waist edge overlap in a vertical direction perpendicular to the longitudinal direction and the lateral direction, and
- wherein the lateral bottom edge of the second waist region covering material is disposed at approximately the same longitudinal position as the front waist edge such that the lateral bottom edge and the front waist edge overlap in the vertical.
A method of forming absorbent articles comprising:
- moving a chassis web in a machine direction, the chassis web comprising an outer cover, an absorbent body, and a chassis web body facing surface;
- applying a first adhesive to the chassis web body facing surface, the first adhesive defining a first adhesive region;
- coupling an elasticated waist member to the chassis web with the first adhesive;
- applying a second adhesive to the elasticated waist member;
- coupling a waist region covering material to the elasticated waist member with the second adhesive;
- and
- severing the chassis web to form an individual absorbent article, the severing step comprises cutting through a portion of the chassis web comprising the first adhesive and the waist region covering material but not the elasticated waist member.
