Dual liquid dispenser package is provided and is operable to supply liquids from liquid supply chambers to liquid reservoirs through liquid supply channels by centrifugal force-induced liquid displacement and flow attendant dispenser package rotation. The supply channels include means to greatly inhibit, if not totally prevent, liquid foaming attendant liquid flow from the supply chambers to the reservoirs. Vents are included to vent the liquid supply chambers to atmosphere to prevent vacuum build-up therein, and include means preventing spillage of the liquids from the dispenser package through the vents. The dispenser package is particularly adapted for use in the supply of two reagent liquids to automated sample liquid analysis systems.

In a liquid dispenser package including, a liquid supply chamber, a liquid reservoir spaced from said liquid supply chamber, a liquid supply channel connecting said liquid supply chamber to said liquid reservoir for liquid flow from said liquid supply chamber to said liquid reservoir, and capsule means containing a predetermined volume of liquid and adapted to introduce said predetermined volume of liquid into said liquid supply chamber and said liquid supply channel, the improvements comprising, said liquid supply chamber and said liquid supply channel being configured, and defining a liquid volume relative to said predetermined liquid volume, operable to prevent liquid flow from said liquid supply chamber through said liquid supply channel to said liquid reservoir with said dispenser package at rest, and to permit centrifugal force-induced displacement and flow of said liquid from said liquid supply chamber to said liquid reservoir through said liquid supply channel upon rotation of said dispenser package at a predetermined rotational speed with said liquid reservoir disposed radially outward of said liquid supply chamber on said dispenser package, said liquid supply channel extending generally horizontally from said said liquid supply chamber to said liquid reservoir and comprising means to inhibit liquid foaming attendant centrifugal force-induced liquid flow from said liquid supply chamber through said liquid supply channel to said liquid reservoir, said liquid foaming inhibiting means comprising said liquid supply channel being of decreasing overall cross-sectional area when viewed along said dispenser package in the direction from said liquid supply chamber to said liquid reservoir, and means defining headspace in said liquid supply channel, said headspace being of sufficient cross-sectional area in combination with the overall decrease in cross-sectional area of said liquid supply channel to inhibit foaming of said liquid attendant the centrifugal force-induced flow of said liquid from said liquid supply chamber to said liquid reservoir.
