Abstract

A dispensing package system for a liquid product including first and second components which must be mixed together prior to use, includes a first container for containing the first component, and a second container for containing the second component prior to use. The first container includes a top dispensing nozzle sealed off by a cap when not in use, and a bottom port sealed by a removable plug from the interior thereof. To mix the components together a user unscrews a cap from the second container, and screws the neck of the second container into a threaded boss of a skirt secured to the bottom of the first container, for forcing a top portion of the neck of the second container into the bottom port of the first container for frictional engagement therewith, and for forcing the plug out of the port into the interior of the first container. The second container is held in position by the skirt, and the joined first and second containers can now be shaken for mixing the first and second components together, and thereafter dispensing the resultant liquid product from the dispensing nozzle of the first container.
