Patent ID: 7977298

Claim:
A kit comprising: an article including a first pouch and a second pouch each made of a flexible polymeric film that is water-soluble under appropriate conditions, the first pouch containing a first solid and/or liquid composition, and the second pouch containing a second solid and/or liquid composition; and an activator material, wherein the activator material is at least one of an acid, a ligand and an enzyme, wherein the polymeric film of the first pouch is more soluble in water in the presence of an activator material than the polymeric film of the first pouch would be in the absence of the activator material, wherein the polymeric film of the first pouch remains substantially intact when immersed in water under a first set of conditions but will readily dissolve or disintegrate when immersed in water under a second set of conditions, wherein the polymeric film of the second pouch will readily dissolve or disintegrate in water under the first set of conditions, wherein the first set of conditions is the absence of the activator material in water at an early stage in a rinse cycle in a wash process, and the second set of conditions is the presence of the activator material in water at a later stage of the rinse cycle in the wash process, and wherein the activator material is separate and discrete from the article comprising the first and second pouches.
