Abstract

A mixing method using a manufacturing apparatus having a mixing machine having a support defining a receiving housing including a first and a second receiving locations configured to receive a first and a second deformable capsules, respectively, the first and second capsules configured to be fluidly linked and containing respectively a first and a second formulations and a second formulations,
an actuation system configured to transmit a pressure force to the first and second capsules to move the content of the first capsule in the second capsule, and vice versa, the mixing machine includes a heater element configured to heat at least one of the first and second capsules when received in the mixing machine, the method includes: heating and/or kneading alternately or simultaneously, setting in motion of the actuation system and heating by the heater element, and maintaining a withdrawal temperature by the heater element, without motion of the actuation system.

First claim

The invention claimed is:

1. A mixing method using a manufacturing apparatus comprising a mixing machine comprising a support defining a receiving housing which defines an insertion aperture, and
a receiving device removably disposed within the insertion aperture of the receiving housing,
the receiving device comprising a first receiving location configured to receive a first deformable capsule and a second receiving location, configured to receive a second deformable capsule, the first and second capsules configured to be fluidly linked to each other and containing respectively a first formulation and a second formulation,
wherein the manufacturing apparatus comprises an actuation system configured to transmit a pressure force to the first and second capsules to move the content of the first capsule in the second capsule, and vice versa,
the mixing machine comprising a heater element configured to heat at least one of the first and second capsules when the first and second capsules are received in the mixing machine,
the mixing method comprising following successive steps:
a heating step and/or a kneading step comprising, alternately or simultaneously, setting in motion of the actuation system and heating by the heater element,
a step of maintaining the temperature by the heater element at a withdrawal temperature, the withdrawal temperature corresponding to a temperature of the heater element between 55° C. and 60° C.

2. The method of claim 1 , wherein the temperature maintenance step is performed without motion of the actuation system.

3. The method of claim 1 , wherein the withdrawal temperature is such that a temperature of the content of the first capsule and/or of the second capsule is between 38° C. and 42° C.

4. The method of claim 1 , wherein the temperature maintenance step is implemented for a non-zero time period.

5. The method of claim 1 , wherein the heating step and/or the kneading step comprise(s):
a step of kneading with heating through setting in motion of the actuation system and heating by the heater element, up to a target temperature; then
a step of cooling with kneading through setting in motion of the actuation system, so that the heater element reaches the withdrawal temperature below the target temperature.

6. The method of claim 1 ,
wherein the heater element further heats one of the first and second receiving locations.

7. The method of claim 6 , wherein the actuation system comprises a first actuation member configured to transmit a pressure force on a first side of the receiving device and a second actuation member configured to transmit a pressure force on a second side of the receiving device, the first and second actuation members exerting alternately forces along a respective first and second actuation stroke, and wherein, prior to the temperature maintenance step, the actuation member acting on the receiving location which is not heated, is actuated.

8. The method of claim 1 , wherein the first receiving location is configured to receive the first capsule, and wherein the second receiving location is configured to receive the second capsule.

9. The method of claim 8 , wherein the actuation system comprises a first actuation member configured to transmit a pressure force on a first side of the receiving device and a second actuation member configured to transmit a pressure force on a second side of the receiving device, the first and second actuation members exerting alternately forces along a respective first and second actuation stroke, the method comprising:
receiving a withdrawal instruction, and
setting in a neutral position after a last action of the second actuation member along the second actuation stroke.

10. The method of claim 9 , wherein the temperature maintenance step is interrupted on the triggering of the step of receiving the withdrawal instruction.

11. The method of claim 8 , wherein the heater element is located in the receiving device.

12. The method of claim 1 , wherein no pressure is transmitted by the actuation system to the receiving device during the temperature maintenance step.

13. The method of claim 1 , wherein the temperature maintenance step is implemented for a non-zero time period less than 15 min.

14. A manufacturing apparatus for the manufacture of a composition comprising a mixing machine comprising:
a support defining a receiving housing which defines an insertion aperture,
a receiving device removably disposed within the insertion aperture of the receiving housing,
the receiving device comprising a first receiving location configured to receive a first deformable capsule and a second receiving location configured to receive a second deformable capsule, the first and second capsules configured to be fluidly linked to each other and containing respectively a first formulation and a second formulation,
at least one actuation system configured to transmit a pressure force to the first and second capsules to move the content of the first capsule in the second capsule, and vice versa, and
a heater element configured to heat at least one of the first or second capsule when the first and second capsules are received in the mixing machine,
wherein the manufacturing apparatus is configured to implement the following steps:
a heating step and/or a kneading step comprising, alternately or simultaneously, setting in motion of the actuation system and heating by the heater element, and
maintaining a temperature by the heater element at a withdrawal temperature corresponding to a temperature of the heater element between 55° C. and 60° C.

15. A mixing method using a manufacturing apparatus comprising a mixing machine comprising:
a support defining a receiving housing which defines an insertion aperture,
a receiving device removably disposed within the insertion aperture of the receiving housing,
the receiving device comprising a first receiving location configured to receive a first deformable capsule and a second receiving location, configured to receive a second deformable capsule, the first and second capsules configured to be fluidly linked to each other and containing respectively a first formulation and a second formulation,
an actuation system configured to transmit a pressure force to the first and second capsules to move the content of the first capsule in the second capsule, and vice versa, and
a heater element configured to heat at least one of the first and second capsules when the first and second capsules are received in the mixing machine,
the mixing method comprising the following successive steps:
a heating step and/or a kneading step comprising, alternately or simultaneously, setting in motion of the actuation system and heating by the heater element,

maintaining a temperature by the heater element at a withdrawal temperature, the withdrawal temperature being such that the temperature of the content of the first capsule and/or of the second capsule is between 35° C. and 50° C.

16. The method of claim 15 , wherein the withdrawal temperature is such that the temperature of the content of the first capsule and/or of the second capsule is between 38° C. and 42° C.
