Abstract

Provided is a powder discharging container. The powder discharging container includes a container main body in which powder is stored, a button part which is disposed at an upper side of the container main body to be pressed by a user and which has a discharge hole formed at one side, a stem which is configured to ascend or descend according to whether the button part is pressed and which has a movement hole formed inside an upper portion to communicate with the discharge hole, a path forming part which is disposed inside the stem, communicates with the inside of the container main body, and has a powder movement path in which the powder moves and an air movement path in which air moves formed therein, and a compression chamber part which is coupled to lower portions of the stem and the path forming part, has a chamber formed therein to store air, and is configured to, as the button part is pressed, inject the air inside the chamber into the movement hole through the air movement path, wherein, as the air is injected from the chamber into the movement hole due to the button part being pressed, the powder inside the container main body moves through the powder movement path and the movement hole and is discharged to the outside through the discharge hole.

First claim

The invention claimed is:

1. A powder discharging container comprising:
a container main body configured to store powder;
a button part disposed at an upper side of the container main body, configured to be pressed by a user, and having a discharge hole formed at one side thereof;
a stem configured to ascend or descend according to whether the button part is pressed and having a movement hole formed inside an upper portion thereof to communicate with the discharge hole;
a path forming part disposed inside the stem, communicating with an inside of the container main body, and having a powder movement path in which the powder moves and an air movement path in which air moves formed therein; and
a compression chamber part coupled to a lower portion of the stem and a lower portion of the path forming part, and having a chamber formed therein to store air, and is configured to, as the button part is pressed, inject the air inside the chamber into the movement hole through the air movement path,
wherein, as the air is injected from the chamber into the movement hole due to the button part being pressed, the powder inside the container main body moves through the powder movement path and the movement hole and is discharged to an outside through the discharge hole.

2. The powder discharging container of claim 1 , wherein the compression chamber part comprises:
an upper housing coupled to an upper portion of the container main body, wherein the stem and the path forming part are inserted into the upper housing;
a lower housing coupled to a lower portion of the upper housing and forming the chamber in which the air is stored;
a piston coupled to the lower portion of the stem and, according to whether the button part is pressed, ascends or descends in close contact with an inner side surface of the lower housing to change a pressure of the air inside the chamber and move the air inside the chamber to the air movement path; and
a nozzle part disposed inside the lower housing and passing through the piston to be coupled to the lower portion of the path forming part, and configured to allow the powder movement path to communicate with the inside of the container main body.

3. The powder discharging container of claim 2 , wherein:
an accommodation hole is formed to pass through the piston and the lower portion of the stem is inserted thereinto;
the nozzle part passes through the piston via the accommodation hole and is coupled to the lower portion of the path forming part; and
the air inside the chamber moves to the air movement path through a separation space between an inner circumferential surface of the accommodation hole and the nozzle part.

4. The powder discharging container of claim 3 , wherein the compression chamber part further comprises a first check valve coupled to an inner side of the accommodation hole and configured to regulate an inflow of air from the air movement path to the chamber through the separation space.

5. The powder discharging container of claim 4 , wherein:
the first check valve comprises:
a first coupling part coupled to the inner side of the accommodation hole; and
a first sealing part extending from the first coupling part toward an outer circumferential surface of the nozzle part; and

the first sealing part comes in close contact with the outer circumferential surface of the nozzle part and blocks the inflow of air from the air movement path to the chamber, but when the piston descends, the first sealing part is spaced apart from the outer circumferential surface of the nozzle part due to an air pressure and allows the chamber and the air movement path to communicate.

6. The powder discharging container of claim 5 , wherein at least a portion of the first sealing part is formed to be inclined upward toward the air movement path.

7. The powder discharging container of claim 5 , wherein:
a stepped part protruding toward the inner side of the accommodation hole is formed at the piston; and
the first coupling part of the first check valve is disposed on the stepped part and pressed by the lower portion of the stem that is inserted into the accommodation hole.

8. The powder discharging container of claim 2 , wherein:
at least one air inlet hole configured to allow the chamber to communicate with the inside of the container main body is formed in an inner lower end surface of the lower housing; and
the compression chamber part further comprises a second check valve configured to regulate movement of the air from the chamber into the container main body through the at least one air inlet hole.

9. The powder discharging container of claim 8 , wherein:
the second check valve comprises:
a second coupling part coupled to the inner lower end surface of the lower housing; and
a second sealing part extending outward from one end of the second coupling part; and

the second sealing part comes in close contact with the inner lower end surface of the lower housing in which the at least one air inlet hole is formed and blocks the movement of the air from the chamber into the container main body through the at least one air inlet hole, but when the piston ascends, the second sealing part is spaced apart from the inner lower end surface of the lower housing due to a pressure of air flowing into the container main body through the powder movement path and allows the chamber to communicate with the inside of the container main body.

10. The powder discharging container of claim 2 , wherein an extension extending a predetermined length downward is formed at a lower portion of the lower housing, wherein the nozzle part ascends or descends in the extension according to whether the button part is pressed.

11. The powder discharging container of claim 10 , further comprising a tube having one end thereof coupled to the extension and an other end thereof extending from a lower end surface of the container main body to a predetermined position and the tube is configured to allow the nozzle part to communicate with the inside of the container main body,
wherein at least a portion of an outer circumferential surface of the other end of the tube is cut out upward and forms a powder inlet.
