Abstract

A multi-phase cosmetic composition mixing pack for mixing immiscible components of a multi-phase cosmetic composition such that they are temporarily miscible includes a container for holding the multi-phase cosmetic composition that has a first open end and a container central axis, and a mixing element disposed within the container and configured to be actuated for mixing immiscible components of the multi-phase cosmetic composition such that they are temporarily miscible, wherein the mixing element is limited to one or more of substantially rotational movement and lateral movement along the container central axis when actuated.

First claim

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:

1. A multi-phase cosmetic composition container, comprising:
a mechanical blender including a plurality of mixing elements disposed about an applicator received within a container reservoir that is at least partially filled with a multi-phase cosmetic composition;
a torque component operably coupled to the mechanical blender, the torque component including a rotational end cap assembly that affixes to the multi-phase cosmetic composition container and engages the mechanical blender so as to rotate or oscillate the plurality of mixing elements responsive to an applied a rotational force; and
wherein the torque component comprises a planetary gear assembly.

2. The multi-phase cosmetic composition container of claim 1 , wherein the torque component is configured to rotate the mixing element along a central axis for a duration and rate sufficient to mix immiscible components of a multi-phase cosmetic composition such that they are temporarily miscible, elements responsive to an applied a rotational force, without contacting the application portion of the applicator received within a container reservoir.

3. The multi-phase cosmetic composition container of claim 1 , wherein the plurality of mixing elements comprises a plurality of blades, each blade having a cross-section having a regular or irregular geometric shape.

4. The multi-phase cosmetic composition container of claim 1 , wherein each of the plurality of mixing elements comprises a unique cross-section.

5. The multi-phase cosmetic composition container of claim 1 , wherein each of the plurality of mixing elements comprises a ribbon or helical structure.

6. The multi-phase cosmetic composition container of claim 1 , wherein the planetary gear assembly includes a sun gear, a plurality of planet gears, and a ring gear.

7. The multi-phase cosmetic composition container of claim 6 , wherein one or more of the plurality of planet gears is coupled to a mixing element and configured to rotate the mixing element in the presence of an applied force.

8. The multi-phase cosmetic composition container of claim 6 , wherein one or more of the plurality of planet gears are coupled to a mixing element and configured to rotate the mixing elements about respective longitudinal axis.
