The screw and piston are threadingly engaged such that rotation of the body and base in opposite directions results in the screw and piston being moved upwards into the body, driving the cosmetic product out through an opening in an upper surface of the body. ## Claims ### Claim 1 A device for dispensing a cosmetic product, the device comprising: a base having an interior space; a screw having at least one external thread and at least one internal thread, the screw disposed within the interior space of the base, the internal thread threadingly engaged with one or more protrusions on the base; a piston having an inner cavity and one or more projections extending into the inner cavity, wherein the projections on the inner cavity of the piston are threadingly engaged with the external thread on the screw, the piston configured to be disposed over the screw within the interior space of the base; a sealing member configured to fit over an upper end of the piston, the sealing member having an oval upper surface; and a body with an open lower end configured to engage an upper end of the base, the body having an inner wall defining a product container, the inner wall having an oval cross section taken perpendicular to a longitudinal axis of the device, the oval cross section configured to receive the oval upper surface of the sealing member in a slidable friction fit; wherein rotation of the base relative to the body causes the screw to rotate, thereby moving the piston and sealing member upwards through the body. ### Claim 2 (depends on 1) The device of claim 1, wherein the base includes a central insert, wherein the interior space is defined between an inner wall of the base and an outer wall of the central insert. ### Claim 3 (depends on 2) The device of claim 2, wherein the one or more protrusions on the base are disposed on the outer wall of the central insert. ### Claim 4 (depends on 3) The device of claim 3, wherein the one or more protrusions on the base are disposed adjacent an upper end of the central insert. ### Claim 5 (depends on 1) The device of claim 1, wherein the sealing member has a cylindrical lower surface configured to fit over a cylindrical upper surface of the piston. ### Claim 6 (depends on 5) The device of claim 5, wherein the oval upper surface of the sealing member is flexible. ### Claim 7 (depends on 1) The device of claim 1, further comprising a collar connected to an upper open end of the body, the collar having an opening therein for dispensing product. ### Claim 8 (depends on 7) The device of claim 7, further comprising a cap configured to be connected to the collar. ### Claim 9 (depends on 1) The device of claim 1, wherein the body is transparent. ### Claim 10 A device for dispensing a cosmetic product, the device comprising: a container configured to hold a volume of cosmetic product, the container having an inner surface with an oval cross section taken perpendicular to a longitudinal axis of the container; and a cosmetic dispensing system coupled to an open lower end of the container and comprising: a base; a hollow screw disposed inside the base, the screw having at least one internal thread and at least one external thread, wherein the at least one internal thread is threadingly engaged with one or more protrusions on the base; a piston configured to fit over the screw and within the base, the piston having one or more projections threadingly engaged with the at least one external thread on the screw; and a sealing member attached to the piston, the sealing member having an oval sealing surface configured to frictionally engage the inner oval surface of the container; wherein the dispensing system is configured such that rotation of the base relative to the container rotates the screw which moves the piston and attached sealing member upwards through the container. ### Claim 11 (depends on 10) The device of claim 10, wherein the base includes a central insert, wherein the one or more protrusions on the base are disposed on an outer wall of the central insert. ### Claim 12 (depends on 11) The device of claim 11, wherein the one or more protrusions on the base include first and second protrusions disposed opposite one another adjacent an upper end of the central insert. ### Claim 13 (depends on 12) The device of claim 12, wherein the one or more projections on the piston include first and second projections disposed opposite one another on a lower end of an inner surface of the piston. ### Claim 14 (depends on 13) The device of claim 13, wherein the screw includes first and second internal threads and first and second external threads, wherein the first and second projections on the piston are threadingly engaged with the first and second external threads, respectively, and the first and second protrusions on the base are threadingly engaged with the first and second internal threads, respectively. ### Claim 15 (depends on 10) The device of claim 10, wherein the base and the container have cylindrical outer surfaces. ### Claim 16 (depends on 15) The device of claim 15, wherein the sealing member has a cylindrical lower surface configured to fit over a cylindrical upper surface of the piston. ### Claim 17 (depends on 10) The device of claim 10, wherein the oval sealing surface of the sealing member is flexible. ### Claim 18 (depends on 10) The device of claim 10, further comprising a collar connected to an upper open end of the container, the collar having an opening therein for dispensing product. ### Claim 19 (depends on 10) The device of claim 10, wherein the container is transparent. ### Claim 20 A device for dispensing a cosmetic product, the device comprising: a base having an interior space; a screw having at least one external thread, and an inner surface having at least one protrusion thereon, the screw disposed within the interior space of the base; a piston having at least one external thread configured to threadingly engage the at least one protrusion on the inner surface of the screw, the piston configured to be disposed within the screw; a sealing member connected to the piston, the sealing member having an oval upper surface; and a body with an open lower end configured to engage an upper end of the base, the body having an inner wall defining a product container, the inner wall having an oval cross section taken perpendicular to a longitudinal axis of the device, the oval cross section configured to receive the oval upper surface of the sealing member in a slidable friction fit, the body having at least one projection on the inner wall, the at least one projection configured to threadingly engage the external thread on the screw; wherein rotation of the body relative to the base causes the screw to move axially upwards into the body, thereby moving the piston and sealing member upwards through the body.
