Uniform delivery of compositions

Abstract

A system for uniformly delivering treatment compositions to fabrics in a fabric article drying appliance. The system also provides for efficient delivery of treatment compositions to fabrics in a fabric article drying appliance. A method is also provided for the uniform and efficient delivery of treatment compositions to fabrics in fabric article drying appliances.

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°; and   e) rotating the tumble dryer concurrent with step d, before step d, after step d, or a combination thereof.   
   
   
       3 . The method of  claim 2  further comprising providing a drum of a tumble dryer associated with the fabric article treating device such that the benefit composition is dispensed from the fabric article treating device into the fabric article drying appliance whereby about 95% or more of the benefit composition dispensed into the drum of the tumble dryer is deposited onto fabric in the tumble dryer. 
   
   
       4 . A method for depositing benefit composition in a fabric article drying appliance, the method comprising:
 a) providing a fabric article treating device, the fabric article treating device 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; and   c) dispensing the benefit composition through the conduit from the source of benefit composition to the nozzle and into the interior of a fabric article drying appliance whereby the uniformity of distribution of the benefit composition onto fabric is at least about 45%.   
   
   
       5 . The method of  claim 4  wherein less than about 10% of the benefit composition is released from the interior of the fabric article drying appliance through a lint screen. 
   
   
       6 . The method of  claim 4  wherein the benefit composition is electrostatically charged. 
   
   
       7 . The method of  claim 4  wherein about 95% or more of the benefit composition dispensed into the interior of the fabric article drying appliance is deposited onto fabric.
