Eco-friendly cosmetic container

A cosmetic container comprising:

• a base assembly including an outer base having an open top and a closed bottom, the outer base having a plurality of notches on an inner surface of the outer base, and a collar configured to fit within the outer base through the open top of the outer base, the collar having an open top and an open bottom, a helical slot and a channel on an inner surface of the collar, an outer ridge on an outer surface of the collar, a plurality of ridges on the outer surface of the collar configured to engage with the plurality of notches on the inner surface of the outer base, and at least one protrusion on the outer surface of the collar;
• a shell configured to fit within the collar through the open top of the collar, the shell having an open top and an open bottom, an outer ridge configured to engage with the channel on the inner surface of the collar to secure the shell to the base assembly, and at least one longitudinal slot extending from the open bottom;
• a cup configured to fit within the shell through the open top of the shell, the cup having an open top and an open bottom, wherein the cup includes at least one post on an outer surface of the cup configured to extend through the at least one longitudinal slot of the shell and interact with the helical slot of the collar;
• a cap that is removably coupled to the base assembly, the cap having an inner channel on an inner surface of the cap configured to engage with the at least one protrusion on the outer surface of the collar to secure the cap to the base assembly;
• and
• wherein the base assembly, the shell, the cup and the cap are all formed from a same material.

• wherein rotation of the base assembly relative to the shell in a first direction causes the at least one post on the outer surface of the cup to move along the helical slot of the collar thereby raising the cup;
• and
• wherein rotation of the base assembly relative to the shell in a second direction causes the at least one post on the outer surface of the cup to move along the helical slot of the collar thereby lowering the cup.
