Absorbent garment with strand coated adhesive components
View Patent ↗An absorbent garment includes a body panel having a terminal waist edge, at least first and second layers terminating at the terminal waist edge and at least one elastic element disposed between the first and second layers. The body panel has at least first and second adhesive regions. The first adhesive region is defined by the at least one elastic element, which is strand coated with a first adhesive. The second region is defined by a control coating of a second adhesive applied between the first and second layers. In one embodiment, the first region has a greater sensory softness than the second region. In one embodiment, the body panel, in an unstretched condition, has a surface softness with a can deviation of coefficient of friction less than about 0.020 in the first adhesive region. A method of assembling an absorbent garment include strand coating at least one elastic element with a first adhesive and applying a control coating of a second adhesive to a portion of at least one of a first and second layer of web material.
1. A method of assembling an absorbent garment comprising:
strand coating at least one waist elastic element with a first adhesive;
applying a control coating of a second adhesive to a portion of one or both of first and second layers of web material having coincident terminal edges along at least one side thereof;
disposing said at least one elastic element between said first and second layers of web material; and
joining said first and second layers of web material with said at least one elastic element strand coated with said first adhesive and said control coating of said second adhesive to form a body panel for use in an absorbent garment, wherein said body panel has at least first and second adhesive regions, wherein said first adhesive region is defined by said at least one waist elastic element individually strand coated with a first adhesive, wherein said the at least one waist elastic element individually strand coated with a first adhesive is the only adhesive joining said first and second layers in said first adhesive region, and the second adhesive region is defined by a control coating of a second adhesive applied between said first and second layers;
wherein said first and second layers are first and second layers of spunbond material, and wherein said body panel in said unstretched condition has a surface softness with a mean deviation of coefficient of friction less than about 0.020 in said first adhesive region.
2. The method of claim 1 wherein said strand coating said at least one elastic element with said first adhesive comprises strand coating a plurality of elastic elements with said first adhesive and wherein said disposing said at least one elastic element between said first and second layers of web material comprises disposing said plurality of elastic elements between said first and second layers of web material in a spaced apart relationship, wherein said plurality of elastic elements define a length of a first adhesive region, wherein said length of said first adhesive region extends to said coincident terminal edges.
3. The method of claim 1 wherein said first adhesive of said strand coated plurality of elastic elements is the only adhesive joining said first and second layers of web material in said first adhesive region.
4. The method of claim 1 wherein said portions of said first and second layers of web material joined with said control coating define a second adhesive regions, wherein at least a first portion of said second adhesive region is free of any elastic elements and at least a second portion of said second adhesive region comprises at least one elastic element.
5. The method of claim 1 wherein said portions of said first and second layers of web material joined with said control coating define a second adhesive regions, wherein said first adhesive region has a greater sensory softness than said second adhesive region.
