Abstract
A cosmetic portioning machine is provided having a mixing chamber, with a plurality of radially-disposed inlets, each of which provides an ingredient. A piston disposed in the mixing chamber defines a mixing volume. A dasher may be disposed in the mixing chamber to mix the ingredients together in the mixing volume so as to form a cosmetic. When the cosmetic product is thoroughly mixed, the piston urges the product out of the mixing chamber and through an outlet. A moveable sealing member is configured to pass through the outlet so as to seal off fluid communication between the mixing chamber and the outlet and to urge any remaining cosmetic product through the outlet.
Claims18
A portioning machine for providing a cosmetic comprising a mixture of at two 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;
- 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 plurality of inlets for providing ingredients into the mixing chamber, the plurality of inlets in fluid communication with the mixing chamber and disposed radially about a circumference of the inner perimeter wall at the proximal end of the mixing chamber;
- for each of the plurality of inlets, a check valve to prevent fluid from being forced into the respective inlet from the mixing chamber.

- 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.
