FIG. 5 is an explanatory drawing illustrating coupling state of a rotation preventing protrusion of a stem and a rotation preventing groove of a support body of the container for discharging powder according to an exemplary embodiment.

[0034] Referring to FIGS. 1 to 5, the container for discharging powder according to an exemplary embodiment includes a container body 100, a button part 200, a stem 300, a content movement part 400 and an opening/closing member 500.

[0035] The container body 100 containing powder comprises a discharging outlet 110 at an upper portion thereof such that the powder contained therein can be discharged.

[0036] At an upper portion of the container body 100 is coupled a support body 600 which is coupled to the discharging outlet 110 and closes an upper end of the discharging outlet 110. At an inner upper side of the support body 600 is equipped an extension part 610 which extends 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 610 is equipped a piston 700 which ascends/descends in a state of being tightly contacted to an inner circumferential surface of the extending part 610 and thereby changes the inner pressure of the container body 100.

[0037] Meanwhile, at both sides of an upper portion of the container body 100 is coupled a pumping guide groove 620 which forms a space such that a button part 200 can ascends/descends and a pumping preventing protrusion 620 which prevents a downward movement of the button part 200. It is preferred to install a fixing protrusion 640, at the pumping guide groove 620 and the pumping preventing protrusion 630, which fixes a pumping guide protrusion 230 of the button part 200, so as to prevent the button part 200 from randomly rotating in a state that the button part 200 completes its rotation either to one side direction or to the other direction.

[0038] Meanwhile, at an inner circumferential surface is formed a rotation preventing groove 650 where a rotation preventing protrusion 340 of the stem 300 so as to prevent the stem 300 from rotating along by the rotation of the button part 200.

[0039] Furthermore, at an upper portion of the support body 600 is installed a spring support part 660 so as to support a spring (S) which restores the button part 200 by providing an elastic force to the stem 300.

[0040] Meanwhile, a shoulder part 800 is coupled at an upper portion of the container body 100, encasing the support body 600, wherein the shoulder part 800 forms a space where a button part to be described later is inserted to ascend/descend, and an over cap 900 is coupled at an outer side of the shoulder part 800, encasing the button part 200, to prevent a malfunction of the button part 200.

[0041] The button part 200, which is rotatably coupled to a stem 300 at an upper portion of the container body 100, ascends/descends according to a user's pressurization and delivers the pressure to the stem 300, comprising a discharging hole 210 at one side thereof such that powder can be discharged.

[0042] At an inner upper side of the button part 200 is installed a guide tube 220 which guides the ascent/descent of an ascending/descending member 500, wherein at both sides of the guide tube 220 is formed a vertical guide groove 221 where a guide protrusion 530 of the ascending/descending member 500 is inserted to guide the vertical movement of the opening/closing member 500.

[0043] Furthermore, at an inner circumferential surface of the button part 200 is installed a pumping guide protrusion 230 which controls the ascending/descending movement of the button part 200, wherein the pumping guide protrusion 230 is placed directly above the pumping preventing protrusion 630 of the support body 600 normally when in in use, and prevents the button part 200 from descending. Meanwhile, when the button part 200 rotates to one side direction for using, the pumping guide protrusion 230 gets out of the pumping preventing protrusion 630, then is placed directly above the pumping guide groove 620, and moves along the pumping guide grooves 620, thereby enabling the button part 200 to ascend/descend.

[0044] At a lower portion of the button part 200 is installed a spring (S) which provides elastic force to an upward direction when a user releases pressurizing the button part 200. The spring is installed between a stem 300 to be described later and a spring support part 660 of the support body 600, and provides an elastic force to the stem 300, thereby enabling the button part 200 to be restored.

[0045] The stem 300 is coupled to a lower portion of the button part 200 and moves along as the button part 200 moves, wherein a movement hole 310 is formed at an inner side thereof such that powder can move toward a discharging hole 210 by controlling the button part 200, and at a side thereof is formed a connecting hole 320 which is connected with the discharging hole 210 such that the powder moving through the movement hole 310 can be discharged through the discharging hole 210.

[0046] At a lower portion of the stem 300 is coupled a piston 700 which is closely contacted to an inner circumferential surface of the extension part 610 so as to change an inner pressure of the container body 100 as moving along with the ascent/descent of the stem 300. The piston 700 ascends/descends in a state of being closely contacted to an inner circumferential surface of the extension part 610 according to whether or not the piston 700 pressurizes the button part 200, and thus changes an inner pressure of the container body 100, such that powder and air move to an upper portion through a powder movement passage 410 of the content movement part 400 and an air movement passage, and thereby are discharged through the discharging hole 210 of the button part 200.

[0047] Meanwhile, at an upper end of the stem 300 is installed a protrusion part 330 which has a spiral guide groove 331 formed at both sides of an outer circumferential surface thereof so as to guide the ascent/descent of the opening/closing member 500, wherein a guide protrusion 530 of the opening/closing member 500 moves along the spiral guide groove 331 when the button part 200 rotates to one side direction or to the other direction, thereby leading to ascending/descending of the opening/closing member 500.

[0048] Furthermore, at an outer circumferential surface of the stem 300 is formed a rotation preventing protrusion 340 which is inserted into a rotation preventing groove 650 of the support body 600 in order to prevent the stem 300 from rotating when the button part 200 rotates.

[0049] The content movement tube 400 is coupled to an inner side of the stem 300 and forms a space where powder and air move. A powder moving passage 410 where powder moves and an air moving passage 420 where air moves are separately formed at an inner side of the content movement part 400.

[0050] Upper ends of the powder moving passage 410 and the air moving passage 420 are connected with the movement hole 310 of the stem 300 such that the powder and air moving respectively through the powder moving passage 410 and the air moving passage 420 can move to the discharging hole 210 via the stem 300.

[0051] At an end of the air moving passage 420 is formed an air compressing hole 421 which has a smaller diameter than that of the air moving passage 420, wherein the air moving through the air moving passage 420 is compressed and is sprayed as passing through the air compressing hole 421, such that the powder moving through the powder moving passage 410 can be sprayed through the discharging hole 210.

[0052] Furthermore, at a lower portion of the powder moving passage 410 is coupled a powder absorbing tube 411 for moving the powder stored in the container body 100 to the powder moving passage 410, wherein the powder absorbing tube 411 moves upwards/downwards along with the stem 300 when the stem 300 ascends/descends according to pressurization of the button part 200, and moves the powder as stirring the powder stored in the container body 100.

[0053] The powder absorbing tube 411 is preferred to be made of soft flexible material not to interfere with a bottom surface of the container body 100 in a process of moving upward/downward.

[0054] The opening/closing member 500 comprises a first sealing part 510, a second sealing part 520, and a guide protrusion 530, such that the opening/closing member 500 can be inserted to an upper portion of the stem 300, ascend to open the movement hole 310 when the button part 200 rotates to one side direction, and descend to close the movement hole 310 when the button part 200 rotates to the other side direction.

[0055] The first sealing part 510 opens/closes the movement hole 310 as being closely contacted to or separated from an inner circumferential surface of the stem 300 according to the ascent/descent of the opening/closing member 500, wherein the first sealing part 510 is closely contacted to an inner circumferential surface of the stem 300 and closes the movement hole 310 in a state that the opening/closing member 500 is lowered, whereas the first sealing part 510 is detached from the inner circumferential surface of the stem 300 and opens the movement hole 310 in a state that the opening/closing member 500 is raised up.

[0056] The second sealing part 520, disposed at an upper portion of the first sealing part 510 and ascending/descending in a state of being closely contacted to an upper inner circumferential surface of the stem 300, closes an inner upper space of the stem 300 disposed higher than the connecting hole 320, such that the powder and air moving through the movement hole 310 is prevented from moving to an upper portion of the stem 300 and thus from being leaked.

[0057] The guide protrusion 530, a pair of which are protrusively formed at both sides of an outer circumferential surface of the opening/closing member 500 and ascend/descend the opening/closing member 500 either by one side rotation or by the other side rotation, is inserted into the vertical guide groove 221 and the spiral guide groove 331 and moves along the vertical guide groove 221 and the spiral guide groove 331 by the rotation of the button part 200, thereby guiding the opening/closing member 500 to ascend/descend.

[0058] Hereinafter, with reference to FIG. 6(a) through FIG. 8(f), a powder-discharging process of a container for discharging powder according to an exemplary embodiment will be described. FIG. 6(a) through FIG. 8(f) are views illustrating an operational state of a container for discharging powder according to an exemplary embodiment.

[0059] First, referring to FIG. 4(a) to FIG. 4(b), when the button part 200 rotates to one side direction in a state that the opening/closing member 500 is lowered, the guide protrusion 530 of the opening/closing member 500 ascends along the vertical guide groove 221 and the spiral guide groove 331 while the opening/closing member 500 is ascending. Due to this, the first sealing part 510 of the opening/closing member 500, closely contacted to an inner circumferential surface of the stem 300, gets separated from the inner circumferential surface of the stem 300, thus opening the movement hole 310.

[0060] As the above, when the movement hole 310 opens, a connecting hole 320 and a discharging hole 210 get connected. Under this state as illustrated in FIG. 7(c) to FIG. 7(d), when the button part 200 is pressurized, the stem 300 coupled at a lower portion of the button part 200 descends. At this time, a piston 700 coupled to a lower portion of the stem 300 descends in a state of being closely contacted to an inner circumferential surface of the extension part 610, thus changing an inner pressure of the container body 100.

[0061] When the inner pressure of the container body 100 is changed through the process in the above, powder is absorbed through the power absorbing tube 411 in a process that the air stored in the container body 100 is discharged to the discharging hole 210 through the air moving passage 420, and then moves to the powder moving passage 410. At this time, the air moving through the air moving passage 420 compresses the air as passing through the air compressing hole 421, and then sprays the air, such that it is possible to spray the powder moving through the powder moving passage 410 through the discharging hole 210.

[0062] Meanwhile, as illustrated in FIG. 8(e) to FIG. 8(f), when the button part 200 rotates to the other side direction in a state that the opening/closing member 500 is raised up, the guide protrusion 530 of the opening/closing member 500 descends along the vertical guide groove 221 and the spiral guide groove 331, thereby leading the opening/closing member 500 to descend. Due to this, the first sealing part 510 of the opening/closing member 500 gets closely contacted to an inner circumferential surface of the stem 300, thereby closing the movement hole 310.

[0063] As the above, when the movement hole 310 is closed by the first sealing part 510, the powder moving through the content movement part 400 is not possible to move to an upper portion; therefore, powder can be prevented from being leaked through the discharging hole 210 no matter whether the container is dropped or shaken. In a state that the movement hole 310 is closed by the first sealing part 510, the connecting hole 320 and the discharging hole 210 are configured to be dislocated.

[0064] The opening/closing member 500 is inserted to the stem 300 in an interior of the button part 200 and ascends/descends according to rotation of the button part 200, thereby opening/closing the movement hole 310. Therefore, there arises no risk of losing the opening/closing member 500, and the problem that a user has to attach or detach the opening/closing member 500 on every use will be solved as well, thereby providing user convenience.

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 certain embodiments and are not intended to limit the meanings of the terms or to restrict the scope as recited by the accompanying claims.
