US 12,599,217 B2 · Cosmetic container for mixing and dispensing two products

Abstract

A cosmetic container that enables a user to easily mix a first product and a second product, that are stored separately within the cosmetic container, with a simple twist of the dialer before the first use. The first product is in a first product container, while the second is in a second product container. The cosmetic container includes the first product container, the second product container, a pump dispenser, an outer cap, a seal cap, a piston, an elevator, and the dialer. The dialer encloses the second product container and, when rotated, moves the elevator, which in turn pushes the piston inside the second product container. The piston, with a central rod, creates an aperture in the seal cap for the second product to flow into the first product container. This process ensures easy mixing before dispensing by removing the outer cap and using the pump dispenser.

A cosmetic container for mixing and discharging two fluid products, the cosmetic container comprises:

a first product contained in a first product container;
a second product stored in isolation from the first product within a reservoir cavity of a second product container, and the second product container attached to an open lower end of the first product container;
a seal cap covering an upper end of the second product container, the seal cap comprising a breakable region on a top wall of the seal cap;
a dialer for actuating a release of the second product into the first product container, the dialer configured to rotate around and enclose the second product container;
a pump dispenser affixed to a neck at an upper end of the first product container, the pump dispenser configured to discharge a mixture of the first product and the second product from the first product container to the outside of the cosmetic container;
a piston positioned within the reservoir cavity beneath the second product;
an elevator movably secured into a lower portion of the second product container, located beneath the piston in the second product container;
wherein both the first product and the second product are liquid products;
wherein a central rod is integrally formed on an upper side of the piston, the central rod includes a slanted upper edge;
wherein turning the dialer initiates a simultaneous upward and rotational movement of the elevator with respect to the second product container, the elevator in turn pushes the piston upward in the reservoir cavity;
wherein ascent of the piston within the reservoir cavity causes the slanted upper edge of the piston to separate the breakable region from the seal cap and create an aperture within the seal cap, further ascent of the piston expels the second product into the first product container;
wherein the second product container includes at least one reservoir sidewall defining the reservoir cavity, wherein an upper end of the at least one reservoir sidewall defines an open upper end of the second product container;
wherein at a lower end of the reservoir cavity, the at least one reservoir sidewall includes a transversely extending annular ring wall, which serves to outline a lower boundary of the reservoir cavity;
and wherein a cylindrical skirt extends downward in an axial direction from an inner edge of the annular ring wall;
wherein the second product container accommodates the elevator in a manner where the elevator seals a lower opening of the reservoir cavity;
and wherein the elevator is threadedly engaged to the cylindrical skirt of the second product container by engaging two opposing inner threads, situated near an upper portion of the cylindrical skirt, with threads formed on an outer surface of the elevator;
and
wherein the breakable region is an area surrounded by an annular groove located on an upper surface of the top wall of the seal cap, the breakable region being separable from the rest of the top wall when subjected to sufficient pressure by the piston.
