         [0029]    Referring to  FIGS. 1 to 3 , a powder-discharging according to an exemplary embodiment of the present invention includes a container body  100 , a button part  200 , and a stem  300 . 
         [0030]    The container body  100  containing powder comprises a discharging outlet  110  at an upper portion thereof such that the powder contained can be discharged. 
         [0031]    At an upper portion of the container body  100  is coupled a support body  500  which is coupled to the discharging outlet  110  and closes an upper end of the discharging outlet  110  and, according to the present invention, it is characterized that at a bottom surface of an upper end of the support body  500  is equipped an extending part  510  which is extended to a lower portion thereof so as to encase an upper inner circumferential surface of the container body  100 , wherein at an inner side of the extending part  510  is equipped a piston  400  which ascends/descends in a state of being tightly contacted with an inner circumferential surface of the extending part  510 , and changes an inner pressure of the container body  100 . 
         [0032]    Meanwhile, at an upper portion of the container body  100  is coupled a shoulder part  700 , encasing the support body  500 , wherein the shoulder part  700  comprises a hollow such that a button part  200  to be explained later is inserted and ascended/descended, and at an outer side is coupled an over cap  800  which encases the button part  200  to prevent malfunction of the button part  200 . 
         [0033]    The button part  200  is coupled to a stem  300  at an upper portion of the container body  100  and delivers pressure to the stem  300  as being ascended/descended according to the presence or absence of a user&#39;s pressurizing, comprising a discharging hole  210  at one side thereof such that powder can be discharged, wherein at an inner side of the button part  200  is coupled a coupling protrusion  220  coupled to a coupling groove  350  of the stem  300  so as to provide a directional property when assembled with the stem  300  such that the discharging hole  210  and an connecting hole  340  of the stem  300  can be communicated. 
         [0034]    Meanwhile, at the button part  200  is coupled an opening/closing member  230  which opens/closes the discharging hole  210  so as to be detachable. 
         [0035]    At a lower portion of the button part  200  is installed a spring (S) that provides elasticity force to an upward direction as releasing the pressurizing force generated when a user presses the button  200 , wherein the spring (S) is installed between a stem  300  to be explained later and a spring support part  600  coupled to an upper portion of the support body  500  and provides an elasticity force to a stem  300 , thereby making it possible for the button  200  to be restored. 
         [0036]    The stem  300  is coupled to a lower portion of the button part  200  and moves along as the button part  200  moves, wherein it is characterized, according to the present invention, that at an inner side of the stem  300  are separately equipped a powder passageway  310  wherein powder moves and an air passageway  320  wherein air moves. 
         [0037]    At a lower portion of the stem  300  is coupled a piston  400  which closely contacts to an inner circumferential surface of the extending part  510  so as to move along with the ascent/descent of the stem  300  and thereby change an inner pressure of the container body  100 , wherein the piston  400  ascends/descends in a state of being closely contacted to an inner circumferential surface of the extending part  510  according to the presence or absence of the button part  200  being pressurized, and thereby changes an inner pressure of the container body  100 , such that powder and air can move upward through the powder passageway  310  and the air passageway  320 , and be discharged through a discharging outlet  210  of the button part  200 . 
         [0038]    At a side surface of the stem  300  is equipped a connecting hole  340  communicated with a discharging hole  210  such that powder moving to an upper portion by operation of the button part  200  can be discharged to the discharging hole  210  of the button part  200 , and at an upper end of the stem  300  is equipped a coupling groove  350  coupled with a coupling protrusion  220  of the button part  200  to provide a directional property such that a discharging hole  210  of the button part  200  and a connecting hole  340  of the stem  300  can be communicated in the process of assembling with the button part  200 . 
         [0039]    Meanwhile, the present invention is characterized in that at a dead-end of the air passageway  320  is equipped an air-compressing hole  330  which has a smaller caliber than the air passageway  320  does, wherein air moving through the air passageway  320  compresses air as moving through the air passageway  320  and then discharges, such that it is possible to discharge powder moving through a powder passageway  310  by way of the discharging hole  210 . 
         [0040]    Furthermore, a powder-absorbing tube  311  is coupled at a lower portion of the powder passageway  310  for moving powder stored in the container body  100  to the powder passageway  310 , wherein the present invention is characterized in that the powder-absorbing tube  311  is configured to move powder as moving along with the stem  300  when the stem  300  ascends/descends by the presence or absence of pressurizing the button part  200 . 
         [0041]    Unlike fluid, powder is not likely to maintain level or fill empty space if not particularly shaken after being discharged, which cause a problem that powder won&#39;t be discharged properly due to empty spaces when in the next use. However, a powder-absorbing tube  311  of the present invention is configured to be moved upward/downward by the control of the button part  200 , such that in the process of an upward/downward movement, powder stored in the container body  100  can be stirred and thereby make it possible to fill spaces to some degree and discharge powder smoothly. 
         [0042]    The powder absorbing tube  311  is preferred to be made of soft flexible materials not to interfere with a bottom surface of the container body  100  in a process of moving upward/downward. 
         [0043]    Meanwhile, it is characterized that at a lower portion of the stem  300  is equipped a powder-moving hole  360  which functions as a passageway where powder moves when the button part  200  is pressurized in a state of the container body  100  being kept upside down, and, as shown in  FIG. 6 , when the button part  200  is pressurized in a state of the container body  100  being kept upside down, powder moves though the powder-moving hole  360 . At this time, a powder-absorbing tube  311  functions as a passageway where air stored in the container body  100 , and it is possible that powder is absorbed through the powder-moving hole  360  and discharged through the discharging hole  210  in a process of air moving through a powder-absorbing tube  311 . 
         [0044]    Hereinafter, with reference to  FIGS. 4 and 5 , a powder-discharging process of a powder-discharging container according to a first exemplary embodiment of the present invention will be described. 
         [0045]      FIGS. 4 and 5  are views illustrating an operational state of a powder-discharging container according to a first exemplary embodiment of the present invention. 
         [0046]    Referring  FIGS. 4 and 5 , after an opening/closing member  230  which opens/closes a discharging hole  210  of a button part  200  is separated and opens a discharging hole  210 , when the button part  200  is pressurized, a stem  300  coupled at a lower portion of the button part  200  descends; at this time, a piston  400  coupled at a lower portion of the stem  300  descends in a state of being contacted to an inner circumferential surface of an extending part  510 , and thereby causes an inner pressure of the stem  300  to be changed. 
         [0047]    When the inner pressure of the container body  100  is changed through the above procedure, powder is absorbed through a powder-absorbing passageway  311  in a process that the air stored in the container body  100  is discharged to a discharging hole  210  via an air passageway  320  and thereby powder is moved to a powder passageway  310 , wherein the air moving through an air passageway  320  compresses air and discharges as moving through an air-compressing hole  330 , thereby allowing powder moving through a power passageway  310  to be discharged through a discharging hole  210 . 
         [0048]    The present invention is configured for a user to directly spray and apply powder to a wanted area of his/her body or hair, which will lead to user convenience. Furthermore, when a user applies powder for makeup by means of a puff, it is possible to spray powder on the puff and then apply the powder onto a face. 
         [0049]    As described above, optimal embodiments have been disclosed in the drawings and the specification. Although specific terms have been used herein, these are only intended to describe the present invention and are not intended to limit the meanings of the terms or to restrict the scope of the present invention as disclosed in the accompanying claims.
