## Abstract

An auto-open compact container has an outer container having a button formed on one side thereof, an outer container lid hinge-coupled to one side of the outer container to be opened/closed, and an inner container which is mounted inside the outer container. An air inlet protrusion is formed in the button such that external air is introduced into the inner container simultaneously while the button is pressed to open the outer container lid. Therefore, an inside of the inner container, which is sealed and evacuated, communicates with the outside, thereby making an operation of pressing the discharge plate smooth.

## Claims

### Claim 1

An auto-open compact container comprising:
an outer container having a button formed on one side of the outer container;
an outer container lid comprising a hinge and a hook, wherein the hinge is coupled to one side of the outer container to be opened or closed;
an inner container which is mounted inside the outer container, and an upper rim of which is sealed by an annular packing member inserted into an inner periphery of the outer container lid;
an inner container cover coupled to an upper portion of the inner container and the inner container cover comprises a cosmetic material suction hole formed at a center of the inner container cover;
a pump installed at an upper portion of the inner container cover to pump a cosmetic material; and
a discharge plate which is coupled to an upper side of the inner container cover to be vertically moved and concurrently coupled to an upper portion of the pump,
wherein the discharge plate comprises a plurality of cosmetic material discharging holes formed in the discharge plate, and the discharge plate comprises an upper portion of which is exposed to an outside such that a user comes into contact with a puff,
wherein the button comprises:
an air inlet protrusion integrally formed at an upper end of the button to push the annular packing member of the outer container lid by a pressing operation of the user so as to allow external air to be introduced into the inner container;
a stopper protrusion integrally formed on an outer side of the upper end of the button and unstopped from the hook formed on one side of the outer container lid by a pressing operation of the user to open the outer container lid; and
return springs protruding from opposite sides of the button in an arc shape to be symmetric to each other, and returning to original positions when the button is pressed and then unpressed while the return springs come into contact with an inner wall of the outer container.

### Claim 2 (depends on 1)

The auto-open compact container of claim 1, wherein a radius of curvature of each of the arc-shaped return springs is smaller than a radius of curvature of the inner wall of the outer container.
