Abstract
This invention claims a disposable article including at least two bonded regions, one of the regions has elastic properties; the other region is different from the first.
Claims19
A disposable article comprising at least two adjacent bonded regions:
- the first bonded region, comprising:
- a first and second substrate;
- and an elastic hot melt adhesive composition between the first and second substrates thereby bonding the first and second substrates to each other;
- the elastic hot melt adhesive composition having a viscosity of less than about 15,000 cps at 350° F. and a set after 50% hysteresis of no greater than about 20%;
- the second bonded region comprising:
- a first substrate and second substrate;
- and a hot melt adhesive composition between the first substrate and second substrates thereby bonding the first substrate and second substrates to each other, the second bonded region having properties different from the first bonded region, the first and second substrate being selected from a group consisting of a nonwoven and a polymer film, and wherein the first and second bonded regions are free of non-adhesive elastic materials.
4 more elements
A disposable article comprising at least one layered bonded region, the layered bonded region comprising:
- a first substrate,
- an elastic hot melt adhesive composition coated in a continuous coating on the first substrate,
- a second hot melt adhesive composition coated in a discontinuous manner on the elastic hot melt adhesive, and
- a second substrate;
- wherein the second substrate is bonded to the elastic hot melt adhesive composition through the second hot melt adhesive composition;
- the elastic hot melt adhesive composition having a viscosity of less than about 15,000 cps at 350° F. and a set after 50% hysteresis of no more than about 20%;
- the first and second substrate being selected from a group consisting of a nonwoven and a polymer film, and wherein the layered bonded region is free of non-adhesive elastic materials.
