Abstract
Official abstract text for this publication.
A process for flushing a dispenser that dispenses liquids, especially perfumes, containing microcapsules. The dispenser has a first reservoir for a first composition containing microcapsules and a second reservoir for a second composition containing a volatile solvent. The dispenser also has a swirl chamber and a premix chamber. The process simultaneously pumps the first and second compositions into the premix chamber and then into the swirl chamber. The pumping of the first composition is halted while the pumping of the second composition continues, and this provides an extra volume of the volatile solvent, which flushes the dispenser to prevent clogging by the microcapsules.
First claim
Opening claim text (preview).
What is claimed is: 1. A process for flushing a dispenser, the process comprising: combining the dispenser with an assembly for flushing that provides a first stage and a second stage for pumping a first composition from a first reservoir and a second composition from a second reservoir into a swirl chamber and premix chamber; wherein during the first stage, the first composition and the second composition are substantially simultaneously pumped from said first and second reservoirs; wherein during the second stage, the pumping of the first composition is halted while the pumping of the second composition continues to provide a flushing volume; wherein the first stage occurs before the second stage; wherein the flushing volume is from about 5 microliters to about 50 microliters; and wherein the dispenser comprises an actuator operatively associated with the first pump and the second pump; and wherein the first composition comprises a carrier that is not a volatile solvent and a plurality of microcapsules and the second composition comprises a volatile solvent.
