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.
Claims72
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;
- wherein said active composition delivery system has a substantially 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 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;
- and
- wherein an active composition is disposed in said at least one pouch.
A method of making an active composition delivery system, said method comprising the steps of:
- a) arranging and joining at least one water-soluble sheet together to form a tube;
- b) closing one end of said tube with a first transverse joint;
- c) filling at least a portion of said tube with an amount of active composition through an open end of said tube;
- d) closing said tube with a downstream transverse joint spaced a predetermined distance from said first transverse joint, with said active composition disposed between said first transverse joint and said downstream transverse joint to form a pouch, said pouch having said active composition disposed therein, and having a top layer and a bottom layer;
- and
- e) forming a plurality of spaced apart, water-soluble joints between said top and bottom layers using water-soluble thread, 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;
- wherein said active composition delivery system has a substantially flat, sheet-like shape when dry, and dissolves when contacted with a sufficient amount of water, thereby releasing said active composition.
