Abstract

The present invention pertains to a trigger sprayer (10) which is connectable to two container volumes (16,18) containing separate liquids. The sprayer (10) has a trigger (76) that is manipulated to draw the separate liquids into two separate pump chambers (56,58) and then supply the two separate liquids from the pump chambers (56,58) to a discharge passage (24) of the sprayer (10). In the discharge passage (24) the separate liquids are mixed together prior to their being dispensed from the discharge passage (24) as a spray.
