Abstract:
The present invention pertains to a trigger sprayer which is connectable to two container volumes containing separate liquids. The sprayer has a trigger that is manipulated to draw the separate liquids into two separate pump chambers and then supply the two separate liquids from the pump chambers to a discharge passage of the sprayer. In the discharge passage the two separate liquids are mixed together prior to their being dispensed from the discharge passage as a spray.
