Abstract

The present invention disclosed herein relates to a container for discharging powder, in particular, a container for discharging powder having a structure wherein a discharging hole of a button part and a connecting hole of a stem are connected or dislocated according to rotation directions, and an opening/closing member is inserted into the stem inside the button part and ascends/descends according to a rotation of the button part, and thereby opens/closes a movement hole of the stem, such that it will solve inconvenience problems such as attaching/detaching the opening/closing member whenever using as well as prevent a risk of losing the opening/closing member, thereby providing user convenience.

First claim

1 . A container for discharging powder, comprising:
a container body storing powder; a button part rotatably disposed at an upper portion of the container body and ascending/descending according to the presence or absence of a user's pressurizing, further comprising a discharging hole, where powder is discharged, at one side thereof; a stem which is disposed at an inner side of the button part and moves along with the movement of the button part, comprising a movement hole at an upper portion thereof such that powder can move according to the manipulation of the button part and further comprising, at a side thereof, a connecting hole connected with the discharging hole such that the powder moving through the movement hole can be discharged through the discharging hole; a content movement part which is disposed at an inner side of the stem, separately forming a powder moving passage where powder moves and an air moving passage where air moves; and an opening/closing member, which is inserted into an upper portion of the stem, ascending and opening the movement hole when the button part rotates to one side direction and closing the movement hole when the button part rotates to the other side direction, wherein the container for discharging powder is characterized in a way that an inner pressure of the container body changes according to pressurization of the button part, and powder and air move into the stem respectively through the powder passageway and the air passageway to the content movement part, thereby making powder discharged and sprayed through the discharging hole by air pressure.

2 . The container for discharging powder of claim 1 , wherein a support body coupled to an upper portion of the container body comprises an extension part which extends to a lower portion so as to encase an upper inner circumferential surface of the container body at an inner upper side thereof.

3 . The container for discharging powder of claim 2 , wherein a piston, closely contacted to an inner circumferential surface of the extension part so as to move along with ascent/descent of the stem and thereby changes an inner pressure of the container body, is coupled at a lower portion of the stem.

4 . The container for discharging powder of claim 1 , wherein a protrusion part forming a spiral guide groove at both sides of an outer circumferential surface thereof so as to guide the ascent/descent of the opening/closing member is provided at an upper end of the button part.

5 . The container for discharging powder of claim 4 , wherein a guide tube guiding the ascent/descent of the ascending/descending member is provided at an inner upper side of the button part, wherein a vertical guide groove guiding the vertical movement of the opening/closing member is provided at both sides of the guide tube.

6 . The container for discharging powder of claim 5 , wherein the opening/closing member comprising:
a first sealing part closing the movement hole by being closely contacted to an inner circumferential surface of the stem in a state of the opening/closing member being lowered, and opening the movement hole by being separated from an inner circumferential surface of the stem in a state of the opening/closing member being raised up; a second sealing part closely contacted to an upper inner circumferential surface of the stem such that powder moving through the movement hole can move to an upper portion of the stem not to the connecting part, thereby being prevented from being leaked; and a guide protrusion inserted to the vertical guide groove and the spiral guide groove and guiding the ascent/descent of the opening/closing member as moving along the vertical guide groove and the spiral guide groove by rotation of the button part.

7 . The container for discharging powder of claim 2 , wherein a rotation preventing protrusion is provided longitudinally at an outer circumferential surface of the stem so as to prevent the stem from being rotated along when the button part rotates, and a rotation preventing groove is provided at an inner circumferential surface of the support body.

8 . The container for discharging powder of claim 7 , wherein a pumping guide groove, forming a space where the button part can ascend/descend, and a pumping preventing protrusion, preventing the button part from moving downwards, are provided at both sides of an outer circumferential surface of the stem.

9 . The container for discharging powder of claim 8 , wherein at an inner circumferential surface of the button part is provided a pumping guide protrusion, disposed directly above the pumping guide groove and moving along the pumping guide groove when the button part rotates to one side direction, and disposed directly above the pumping preventing protrusion and preventing the button part from descending when the button part rotates to the other side direction.

10 . The container for discharging powder of claim 1 , wherein at an end of an air moving passage is provided an air compressing hole whose diameter is smaller than that of an air moving passage such that it is possible to compress and spray air.

11 . The container for discharging powder of claim 1 , wherein at a lower portion of the powder moving passage is coupled a powder absorbing which moves the powder stored in the container body to the power moving passage, wherein the powder absorbing tube moves upwards/downwards according to the presence/absence of pressurization of the button part and stirs the powder stored in the container body.
