Method for packaging, mixing and dispensing a plurality of substances

Claim 1

A METHOD FOR PACKAGING, EXTEMPORANEOUSLY MIXING AND THEN DISPENSING UNDER A DECREASING DISPENSING PRESSURE, TWO SUBSTANCES OF WHICH AT LEAST ONE IS A LIQUID, SAID METHOD COMPRISING THE STEPS OF: PROVIDING TWO CONTAINERS OF IDENTICAL SIZE AND SHAPE, ONE OF SAID CONTAINERS BEING A DISPENSING CONTAINER AND THE OTHER OF SAID CONTAINERS BEING AN AUXILIARY CONTAINER; PROVIDING AT ONE END OF SAID DISPENSING CONTAINER, A VALVE HAVING AN OUTLET PIECE DISPLACEABLE BY MANUAL PRESSURE FROM A FIRST CLOSED POSITION TO A SECOND OPENED POSITION; PROVIDING AT ONE END OF SAID AUXILIARY CONTAINER, A VALVE HAVING AN OUTLET PIECE DISPLACEABLE BY MANUAL PRESSURE FROM A FIRST OF CLOSED POSITION TO A SECOND OPENED POSITION; ONE OF SAID OUTLET PIECES BEING FORMED AS A MALE PART AND THE OTHER OF SAID OUTLET PIECES BEING FORMED AS A FEMALE PART, SAID OUTLET PIECES THEREBY BEING INTERCONNECTABLE WITH ONE ANOTHER; INTRODUCING A MEASURED VOLUME OF THE LIQUID SUBSTANCE INTO SAID AUXILIARY CONTAINER AND INTRODUCING A MEASURED VOLUME OF THE OTHER SUBSTANCE INTO SAID DISPENSING CONTAINER, TEH COMBINED VOLUMES OF SAID TWO INTRODUCED SUBSTANCES BEING SUBSTANTIALLY SMALLER THAN THE CAPACITY OF SAID DISPENSING CONTAINER; FURTHER INTRODUCING INTO SAID DISPENSING CONTAINER AN INERT GAS UNDER A PRESSURE HIGHER THAN ATMOSPHERIC PRESSURE BUT LOWER THAN THE REQUIRED INITIAL DISPENSING PRESSURE VALUE; FURTHER INTRODUCING INTO SAID AUXILIARY CONTAINER AN INERT GAS UNDER A PRESSURE CAPABLE OF COMPLETELY EXPELLING THE LIQUID FROM SAID AUXILIARY CONTAINER INTO SAID DISPENSING CONTAINER AND OF THEREBY INCREASING THE GAS PRESSURE IN SAID DISPENSING CONTAINER TO SAID INITIAL DISPENSING PRESSURE VALUE; COUPLING SAID AUXILIARY CONTAINER AND SAID DISPENSING CONTAINER TOGETHER WITH THE INTERIOR OF ONE OF SUCH CONTAINERS COMMUNICATING WITH THE INTERIOR OF THE OTHER, SUCH COUPLING BEING EFFECTED BY CONNECTING SAID MALE AND FEMALE VALVE OUTLET PIECES AND EXERTING A MANUAL PRESSURE THEREUPON FOR DISPLACING SAID VALVE PIECES TOWARD THEIR RESPECTIVE OPENED POSITIONS, THEREBY ENTIRELY EXPELLING THE LIQUID SUBSTANCE FROM THE AUXILIARY CONTAINER INTO SAID DISPENSING CONTAINER, AND SIMULTANEOUSLY INCREASING THE GAS PRESSURE IN SAID DISPENSING CONTAINER TO SAID INITIAL DISPENSING PRESSURE VALUE; UNCOUPLING SAID TWO CONTAINERS FROM EACH OTHER; MOUNTING A SPRAY HEAD ON THE OUTLET PIECE OF SAID DISPENSING CONTAINER VALVE; AND, ACTUATING SAID SPRAY HEAD TO THEREBY DISPENSE THE MIXTURE OF SAID TWO SUBSTANCES FROM SAID DISPENSING CONTAINER IN THE FORM OF AN AEROSOL SPRAY.

Claim 2

A METHOD FOR PACKAGING, EXTEMPORANEOUSLY MIXING AND THEN DISPENSING UNDER A DECREASING DISPENSING PRESSURE, TWO SUBSTANCES OF WHICH AT LEAST ONE IS A LIQUID, SAID METHOD COMPRISING THE STEPS OF: PROVIDING TWO CONTAINERS OF IDENTICAL SIZE AND SHAPE, ONE OF SAID CONTAINERS BEING A DISPENSING CONTAINER AND THE OTHER OF SAID CONTAINERS BEING AN AUXILIARY CONTAINER; PROVIDING AT ONE END OF SAID DISPENSING CONTAINER, A VALVE HAVING AN OUTLET PIECE DISPLACEABLE BY MANUAL PRESSURE FROM A FIRST CLOSED POSITION TO A SECOND OPENED POSITION; PROVIDING AT ONE END OF SAID AUXILIARY CONTAINER, A VALVE HAVING AN OUTLET PIECE DISPLACEABLE BY MANUAL PRESSURE FROM A FIRST OF CLOSED POSITION TO A SECOND OPENED POSITION; ONE OF SAID OUTLET PIECES BEING FORMED AS A MALE PART AND THE OTHER OF SAID OUTLET PIECES BEING FORMED AS A FEMALE PART, SAID OUTLET PIECES THEREBY BEING INTERCONNECTABLE WITH ONE ANOTHER; INTRODUCING A MEASURED VOLUME OF THE LIQUID SUBSTANCE INTO SAID AUXILIARY CONTAINER AND INTRODUCING A MEASURED VOLUME OF THE OTHER SUBSTANCE INTO SAID DISPENSING CONTAINER, TEH COMBINED VOLUMES OF SAID TWO INTRODUCED SUBSTANCES BEING SUBSTANTIALLY SMALLER THAN THE CAPACITY OF SAID DISPENSING CONTAINER; FURTHER INTRODUCING INTO SAID DISPENSING CONTAINER AN INERT GAS UNDER A PRESSURE HIGHER THAN ATMOSPHERIC PRESSURE BUT LOWER THAN THE REQUIRED INITIAL DISPENSING PRESSURE VALUE; FURTHER INTRODUCING INTO SAID AUXILIARY CONTAINER AN INERT GAS UNDER A PRESSURE CAPABLE OF COMPLETELY EXPELLING THE LIQUID FROM SAID AUXILIARY CONTAINER INTO SAID DISPENSING CONTAINER AND OF THEREBY INCREASING THE GAS PRESSURE IN SAID DISPENSING CONTAINER TO SAID INITIAL DISPENSING PRESSURE VALUE; COUPLING SAID AUXILIARY CONTAINER AND SAID DISPENSING CONTAINER TOGETHER WITH THE INTERIOR OF ONE OF SUCH CONTAINERS COMMUNICATING WITH THE INTERIOR OF THE OTHER, SUCH COUPLING BEING EFFECTED BY CONNECTING SAID MALE AND FEMALE VALVE OUTLET PIECES AND EXERTING A MANUAL PRESSURE THEREUPON FOR DISPLACING SAID VALVE PIECES TOWARD THEIR RESPECTIVE OPENED POSITIONS, THEREBY ENTIRELY EXPELLING THE LIQUID SUBSTANCE FROM THE AUXILIARY CONTAINER INTO SAID DISPENSING CONTAINER, AND SIMULTANEOUSLY INCREASING THE GAS PRESSURE IN SAID DISPENSING CONTAINER TO SAID INITIAL DISPENSING PRESSURE VALUE; UNCOUPLING SAID TWO CONTAINERS FROM EACH OTHER; MOUNTING A SPRAY HEAD ON THE OUTLET PIECE OF SAID DISPENSING CONTAINER VALVE; AND, ACTUATING SAID SPRAY HEAD TO THEREBY DISPENSE THE MIXTURE OF SAID TWO SUBSTANCES FROM SAID DISPENSING CONTAINER IN THE FORM OF AN AEROSOL SPRAY.
