Abstract
An active composition delivery system having a water-soluble top layer, a water-soluble bottom layer, and an active composition disposed therebetween. The water-soluble top and bottom layers are joined together to form a pouch sized and shaped to hold an amount of an active composition. The active composition delivery system further includes a plurality of water-soluble joints, joining the top and bottom water-soluble layers.
Claims39
An active composition delivery system comprising:
- at least one water-soluble sheet arranged and joined together to form at least one pouch having a top layer and a bottom layer, and being surrounded by joined edges;
- an active composition disposed in said at least one pouch;
- and
- water-soluble thread forming a plurality of spaced apart, water-soluble joints between said top and bottom layers, said water-soluble joints being numbered and arranged in a region surrounded by said joined edges to limit a maximum thickness of said at least one pouch, and wherein said water-soluble joints are configured to allow a gap between the top and bottom layers at said water-soluble joints to control distribution of the active composition within the at least one pouch, wherein said active composition delivery system has a flat, sheet-like shape when dry, and dissolves when contacted with a sufficient amount of water, thereby releasing said active composition.
A method for making an active composition delivery system, comprising using a water-soluble thread to join together at least one water-soluble sheet arranged to form at least one pouch having a top layer and a bottom layer, and being surrounded by joined edges;
- wherein the water-soluble thread forms a plurality of spaced apart, water-soluble joints between said top and bottom layers, said water-soluble joints being numbered and arranged in a region surrounded by said joined edges to limit a maximum thickness of said at least one pouch, and
- wherein said water-soluble joints are configured to allow a gap between the top and bottom layers at said water-soluble joints to control distribution of an active composition with the at least one pouch.
