1. A method for depositing benefit composition in the drum of a tumble dryer, the method comprising:
- a) providing a pump, the pump comprising a conduit wherein the conduit includes an inlet and a discharge and a nozzle connected to the discharge of the conduit;
b) placing the inlet of the conduit in communication with the source of benefit composition wherein the inlet of the conduit is in communication with a source of benefit composition;
c) dispensing the benefit composition through the conduit from the source of benefit composition to the nozzle and into the drum of the tumble dryer whereby the benefit composition has a mean droplet size of from about 100 microns to about 1000 microns, a linear velocity through the nozzle of between about 0.05 m/second and about 2 m/second, and wherein the nozzle is positioned in the dryer drum in quadrant one, quadrant two, quadrant three, quadrant four, or a combination thereof, and wherein the nozzle when present in quadrant one has a tilt angle ranging from about 80°
to the left to about 45°
to the right and from about 45°
up to about 35°
down;
when present in quadrant two the nozzle has a tilt angle ranging from about 80°
to the right to about 45°
to the left and from about 45°
up to about 15°
down;
when present in quadrant three the nozzle has a tilt angle ranging from about 80°
to the right to about 45°
to the left and from about 45°
up to about 15°
down;
when present in quadrant four the nozzle has a tilt angle ranging from about 80°
to the left to about 15°
to the right and from about 45°
up to about 15°
down, and combinations thereof.

2. A method for providing efficient deposition of a benefit agent used to treat fabric, the method comprising:
-
a) providing a fabric article treating device; b) providing a benefit composition; c) associating the fabric article treating device with the benefit composition; d) discharging the benefit composition from the fabric article treating device into the drum of a tumble dryer whereby at the discharge of the fabric article treating device the benefit composition has a cone angle between about 35° and
about 150°
; ande) rotating the tumble dryer concurrent with step d, before step d, after step d, or a combination thereof. - View Dependent Claims (3)
