## Abstract

The present invention relates to a refill container using double injection, comprising: a refill container for containing a cosmetic material, wherein the refill container is formed of a synthetic resin or a metallic material and has an impregnation member in which the cosmetic material is impregnated; a refill container holder which is coupled to the top of the refill container; and a refill container cover which is opened and closed by being hinge-coupled to the refill container holder, wherein the refill container holder is formed by doubly injecting or insert-injecting a packing part of an elastic material therein, and the top of the refill container and the packing part are coupled when the refill container and the refill container holder are coupled.

## Claims

### Claim 1

A refill container using double injection molding, the refill container comprising:
a refill container (10) containing cosmetics;
a refill container holder (20) coupled to an upper portion of the refill container (10); and
a refill container lid (50) connected to the refill container holder (20) to be opened and closed,
wherein a packing part (30) of an elastic material is formed to an inside of the refill container holder (20) through double-injection molding or insert molding on a portion where an upper end of the refill container (10) is coupled, a control protrusion wheel coupling groove (26) is formed on a low portion of one side of the refill container holder (20), and a control protrusion wheel (33) for controlling an injection flow is formed in the control protrusion wheel coupling groove (26).

### Claim 2 (depends on 1)

The refill container using double injection molding of claim 1,
further comprising an impregnation member (60) impregnated therein with the cosmetics and mounted in the refill container (10).

### Claim 3 (depends on 1)

The refill container using double injection molding of claim 1, wherein the refill container (10) is formed on an outer peripheral surface thereof with a first latching protrusion wheel (16) and the refill container holder (20) is formed on an inner peripheral surface thereof with a second latching protrusion wheel (22) coupled to the first latching protrusion wheel (12).

### Claim 4 (depends on 1)

The refill container using double injection molding of claim 1, wherein the refill container (10) is formed of synthetic resin material.

### Claim 5 (depends on 1)

The refill container using double injection molding of claim 1, wherein the refill container (10) is formed of at least one of stainless steel, iron (Fe), aluminum (Al), copper (Cu), tungsten (W), nickel (Ni), tin (Sn), magnesium (Mg), calcium (Ca), titanium (Ti), zinc (Zn), and gallium (Ga).

### Claim 6 (depends on 1)

The refill container using double injection molding of claim 1, wherein the packing part (30) is formed of at least one of thermo plastic elastomer (TPE), polyethylene (PE), natural rubber, urethane rubber, nitrile-butadiene rubber (NBR), and silicone.

### Claim 7 (depends on 1)
