Abstract

The present invention relates t o a powder-discharging container comprising an air passage and a powder passageway, which are formed on the inside of a stem, so that air and powder can pass through separately, thereby enabling spraying of powder passing through the powder passageway by means of air passing through the air passageway, when a button portion is pressed.

First claim

What is claimed is:

1. A powder-discharging container comprising:
a container body containing powder;
a button part disposed at an upper portion of the container body and ascending or descending according, respectively, to the absence or presence of pressure applied to the button part, further comprising a discharging hole at one side thereof such that powder is discharged;
a stem coupled to a lower portion of the button part and moving along with the movement of the button part, at an inner side thereof separately comprising a powder passageway wherein powder moves and an air passageway wherein air moves; and
a support body coupled to an upper portion of the container body, the support body, at a bottom surface of an upper end thereof, equipped with an extending part which extends toward a lower portion of the container body so as to encase an upper inner circumferential surface thereof,
wherein a piston is coupled at a lower portion of the stem, and closely contacted to an inner circumferential surface of the extending part such that the piston moves along with ascent or descent of the stem and thereby changes an inner pressure of the container body, and
wherein an inner pressure of the container body changes according to whether pressure is applied to the button part, and powder and air move into the stem respectively through the powder passageway and the air passageway, thereby making powder discharged by air pressure through the discharging hole.

2. The powder-discharging container of claim 1 ,
wherein an air-compressing hole is equipped at a dead-end of the air passageway of the stem, having a smaller caliber than the air passageway such that powder moving upward by control of the button part can be discharged to the discharging hole.

3. The powder-discharging container of claim 1 ,
wherein a connecting hole is equipped at the stem, connected with the discharging hole such that powder moving upward by the control of the button part can be discharged to the discharging hole.

4. The powder-discharging container claim 3 ,
wherein a coupling groove is equipped at an upper end of the stem, providing a directional property when the button part is assembled such that a discharging hole of the button part and a connecting hole of the stem can be communicated with,
wherein a coupling protrusion is coupled to the coupling groove at an inner side of the button part.

5. The powder-discharging container of claim 1 ,
wherein a powder-absorbing tube is coupled at a lower portion of the powder passageway moving powder stored in the container body to the powder passageway.

6. The powder-discharging container of claim 5 ,
wherein the powder-absorbing tube stirs powder stored in the container body by moving upward or downward according, respectively, to the absence or presence of pressure applied to the button part.

7. The powder-discharging container of claim 5 ,
wherein a powder-moving hole equipped at a lower portion of the stem functions as a passageway where powder moves when the button part is pressurized in a state of the container body being kept upside down,
wherein the powder-absorbing tube functions as a passageway wherein air stored in the container body moves.

8. The powder-discharging container of claim 1 ,
wherein an opening/closing member is coupled detachably at the button part so as to open/close the discharging hole.
