PURPOSE: To dispense simultaneously two kinds of liquid held respectively in one container by providing a concentric tubular passage through which each liquid flows when pressure is applied to an outer container, and to vary the ratio of the two liquids by adjusting the length of the common conduit of an exit section. CONSTITUTION: A dispenser has a tubular plug 12 fixed at an open neck 4 of a blow molded container 2, and the plug 12 has an axial center hole 16 penetrating to a chamber 22 formed at its lower end and a spoke-like conduit 20. An injector head 32 is fixed at the lower end of the plug 12 and the center of the head 32 is connected with the upper end of a long and slender bag 24 made of flexible materials. A slender exit tube 38 is set at the center of the head 32 and is projected concentrically to the center hole 16. Two liquids, flowed through the exit tube 38 and the center hole 16, join at a common conduit 54 and are dispensed. The ratio of the two liquids is adjustable by varying the insert length of a sleeve 48 installed in the hole 16. |
