Abstract
A method for treating a stained fabric using a package is disclosed. The package can have a backing layer having a second side and a pouch layer joined thereto to form a pouch. A fluid pervious contact substrate can be joined to a first side of the backing layer. The pouch can contain a stain treatment fluid. The method comprises bending the backing layer, dispensing the stain treatment fluid to the fluid pervious contact substrate through a portion of the backing layer; gripping the backing layer and rubbing the stained fabric with the contact substrate.
Claims20
A method for treating a grease, lard or oil stained fabric comprising the steps of:
- providing a package comprising:
- a backing layer having a first side opposing a second side, said first side of said backing layer having a line of weakness, said second side having a first planar region and a second planar region on opposing sides of said line of weakness;
- a pouch layer joined with said second side of said backing layer thereby forming a pouch, said pouch containing a stain treatment fluid;
- and
- a fluid pervious contact substrate joined to said first side of said backing layer proximal said line of weakness;
- wherein said package has a first position in which said first planar region and said second planar region are substantially in plane with one another;
- wherein said package has a second position in which said first planar region and said second planar region are in a substantially angularly facing relationship;
- wherein in said first position at least a portion of said first planar region and at least a portion of said second planar region are integral with one another and in said second position at least a portion of said backing layer is discontinuous across said line of weakness;
- wherein in said second position said pouch is in fluid communication with said first side of said backing layer;
- and
- wherein said stain treatment fluid comprises from about 0.001% to about 99.99%, by weight of said stain treatment fluid, of a surfactant;
- bending said backing layer about said line of weakness to move said first planar region and said second planar region into a substantially facing relationship thereby making a portion of the backing layer to be discontinuous across said line of weakness;
- dispensing said stain treatment fluid to said fluid pervious contact substrate through said portion of said backing layer that is discontinuous across said line of weakness to said fluid pervious contact substrate joined to said first side of said backing layer proximal said line of weakness;
- gripping said backing layer and rubbing said stained fabric with said contact substrate;
- and
- acquiring a component of the stain from said stained fabric with said contact substrate;
- wherein the contact substrate comprises a fibrous material having Hansen solubility parameters that lie in the same general region of Hansen space as the grease, lard or oil stain being treated, such that the stain is transferred from the stained fabric to the contact substrate.
