Cosmetics portioning machine

A portioning machine for providing a cosmetic comprising a mixture of at least first and second ingredients, the portioning machine comprising:

• a mixing chamber, the mixing chamber having a longitudinal axis and an inner perimeter wall extending parallel to the longitudinal axis, the mixing chamber having a distal end and a proximal end;
• a first inlet for providing the first ingredient, the first inlet being in fluid communication with the mixing chamber;
• a second inlet for providing the second ingredient, the second inlet being in fluid communication with the mixing chamber;
• an outlet in fluid communication with the mixing chamber;
• a piston disposed in the mixing chamber and configured to move towards and away from the proximal end, the piston having a face extending transversely with respect to the longitudinal axis and being substantially in contact with the inner perimeter wall, such that the piston and the inner perimeter wall define a volume, and the face preventing flow of fluid therethrough into or out of the volume;
• a dasher disposed in the mixing chamber and configured to move towards and away from the proximal end in the volume, the dasher being configured to mix fluid in the volume and to permit the passage of fluid past a proximal end of the dasher;
• and
• a moveable sealing member configured to pass through the outlet so as to seal off fluid communication between the mixing chamber and the outlet and to urge fluid through the outlet.
