摘要

A dispenser for applying at least two compositions, the dispenser including at least two reservoirs for storing the at least two compositions, at least two pumps for pumping the at least two compositions, a premix chamber for mixing the two compositions, at least two channels for delivering the compositions from the reservoirs to the premix chamber, an exit orifice, optionally a swirl chamber, and an actuator.

主权项

1. A dispenser comprising:
a first reservoir, the first reservoir comprising a first pump, the first pump comprising a first piston; a second reservoir, the second reservoir comprising a second pump, the second pump comprising a second piston; a first channel having a proximal end and a distal end; a second channel having a proximal end and a distal end; an exit orifice; a premix chamber; a swirl chamber; and an actuator; wherein the proximal end of the first channel is in liquid communication with the first pump and the distal end of the first channel is in liquid communication with the premix chamber; wherein the proximal end of the second channel is in liquid communication with the second pump and the distal end of the second channel is in liquid communication with the premix chamber; wherein the premix chamber is in liquid communication with the swirl chamber; wherein the swirl chamber is in liquid communication with the exit orifice; wherein said first piston and second piston are operatively associated with the actuator; wherein the first reservoir further comprises a first composition and the second reservoir further comprises a second composition; wherein the first composition comprises a plurality of microcapsules and the second composition comprises a volatile solvent; and wherein the first piston travels a shorter distance in its pump as compared with the distance traveled by the second piston in its pump, thereby providing flushing of said premix chamber, swirl chamber and exit orifice by said second composition.
