• an input pipe disposed inside the second container and attached to the sealing device at the input neck;
• an output pipe disposed inside the second container and attached to the sealing device at the output neck;
• a tube system configured to combine the first and second substances into one combined substance, mix the combined substance, and dispense the mixed substance;
• a feeding tube connected to the tube system and configured to receive the mixed substance from said tube system;
• and
• a fluid-impermeable enclosure enclosing the first container, the second container, and the tube system,
• wherein the tube system comprises:
• a main tube;
• a first valve connected between the first container and one end of the main tube;
• a second valve connected between the main tube and the feeding tube;
• and
• a third valve connected between the main tube and the input neck, and
• wherein the main tube comprises:
• a first tube section connecting the first valve and a first Y-connector;
• a second tube section connecting the output neck and the first Y-connector;
• a third tube section connecting the first Y-connector to a second Y-connector;
• a fourth tube section connecting the second Y-connector to the third valve;
• a fifth tube section connecting the second Y-connector to the second valve;
• and
• a sixth tube section connecting the third valve to the input neck.
