Abstract: A container comprises a flexible main chamber and a mixing chamber positioned above the main chamber and including a passage way into the main chamber. A removable plug selectively seals the passage way so that after the main chamber is filled with a first material, the plug can be inserted into the passage way and the mixing chamber filled with a second material. A cap closes the mixing chamber and selectively engages the plug so that after the cap has been placed on the mixing chamber, removal of the cap will also unseal the passageway causing the tow materials to be mixed in the main chamber. A dispensing chamber having an outlet spout is also provided in the container. A filling tube within the container connects the main chamber to the dispensing chamber.
