Description:
BACKGROUND 
       [0001]    The present disclosure relates to a button-type pencil cosmetic dispenser, the button-type pencil cosmetic dispenser including a container body ( 110 ) forming a discharging hole ( 111 ), through which contents is discharged, at an upper portion thereof; a piston ( 200 ) discharging contents to the discharging hole ( 111 ) while ascending/descending inside the container body ( 110 ); a first rotation member ( 300 ) coupled at a bottom surface of the piston ( 200 ), forming a first screw thread ( 301 ) at an outer circumferential surface thereof, a flat surface ( 302 ) vertically cut flat at an upper end part thereof, and a protrusion ( 310 ) at a lower end part; a second rotation member ( 400 ) screw-coupled with the first screw thread ( 301 ) of the first rotation member ( 300 ), comprising an engaging screw protrusion part ( 410 ) which controls an upward movement of the first rotation member ( 300 ) when meeting the protrusion ( 310 ), and further comprising a second screw thread ( 401 ) at an outer circumferential surface thereof; a third rotation member ( 500 ), screw-coupled with the second rotation member ( 400 ) and provided with a third screw thread ( 501 ) which is screw-coupled with the second screw thread ( 401 ); and a rotation conversion means ( 600 ) coupled to the third rotation member ( 500 ), and rotating the third rotation member ( 500 ) to one side direction according to a vertical motion of a button ( 660 ). 
         [0002]    Generally, a pencil-type cosmetic dispenser is used by discharging contents stored inside a dispenser through a discharging hole by rotating a handle to one side direction, and mostly, contents stored in the dispenser are liquid type. 
         [0003]    Conventional pencil-type cosmetic dispensers as in the above are usually screw types, and in case of a screw type, a screw which raises a piston is equipped at a lower portion of a dispenser. 
         [0004]    Due to this, there should be an enough height to hold the length of a screw which raises the piston, and thus an unnecessary space is needed. Therefore, there arises a difficulty in storing a lot of amount of contents inside the dispenser. 
         [0005]    Additionally, a user should hold a dispenser with one hand and rotate a handle with the other hand in order to discharge contents, causing a problem of using both hands.

     DETAILED DESCRIPTION 
       [0020]    Hereinafter, specific characteristics and advantages of the present embodiments will be described in detail with reference to the accompanying drawings. The same reference numerals provided in the drawings indicate the same members. Moreover, detailed descriptions related to well-known functions or configurations will be ruled out in order not to unnecessarily obscure subject matters of the present embodiments. 
         [0021]    A button-type pencil cosmetic dispenser  100 , as illustrated in  FIGS. 1 and 2  in a large scale, includes a container body  110 , a piston  200 , a first rotation member  300 , a second rotation member  400 , a third rotation member  500 , and a rotation conversion means  600 . 
         [0022]    Firstly, a container body  110  will be described. The container body, as illustrated in  FIGS. 2 and 3 , stores contents at an interior thereof, and has a discharging hole  111 , where contents is discharged, at an upper portion thereof. 
         [0023]    Next, a piston  200  will be described. The piston  200 , as illustrated in  FIGS. 2 and 3 , discharges contents through the discharging hole  111  as ascending/descending inside of the container body  110 . 
         [0024]    Next, the first rotation member  300 , coupled to a lower surface of the piston, as illustrated in  FIG. 2 , is coupled to a lower surface of the piston  200 , and has a first screw thread  301  provided at an outer circumferential surface thereof, a flat surface  302  cut flat vertically provided at an upper end thereof, and a protrusion  310  provided at a lower end thereof. 
         [0025]    Next, a second rotation member  400  will be described. The second rotation member  400 , as illustrated in  FIGS. 2 and 3 , is provided with an engaging screw protrusion part  410  which is screw-coupled, fitted with the first screw thread  301  of the first rotation member  300 , and controls an upward movement of the first rotation member  300  when meeting the protrusion  310 , further comprising a second screw thread  401  at an outer circumferential surface thereof. 
         [0026]    The protrusion  310  in the above controls the upward movement by the engaging screw protrusion part  410  formed at an upper end of the second rotation member  400  and thereby prevents the first rotation member  300  from being separated from the second rotation member  400 . 
         [0027]    Furthermore, the protrusion  310  induces the second rotation member  400  to ascend after the first rotation member  300  reaches a top dead point. 
         [0028]    Meanwhile, it is preferred that a separation preventing member  420  is provided at a lower end of the second rotation member  400  for preventing the second rotation member  400  from being separated from a third rotation member  500 . 
         [0029]    Meanwhile, it is preferred that the piston  200  is made to have only a vertical movement inside the container body  110 , but not to have a rotational movement. At this time, the rotational force delivered to the piston  200  through the first rotation member  300  and the second rotation member  400  is far smaller than the operational force delivered for the piston  200  to ascend/descend by the first rotation member  300 . Therefore, an ascending distance while the first rotation member  300  or the second rotation member  400  is making one rotation becomes a pitch of the first screw thread  301  or the second screw thread  401 . Since a torque applied during one rotation, assuming there is no work loss, is converted into a force applied while ascending as much as the ascending distance, a rotational force by the torque is much smaller than the operational force delivered for ascending/descending. Accordingly, whereas the rotational force is much smaller than a frictional force received when the piston  200  contacts an inner wall of the container body  110 , the operational force received for ascending/descending is larger than the frictional force received when the piston  200  contacts an inner wall of the container body  110 , such that the piston  200  can be maintained not to be rotated on the container body  110 , simultaneously making an ascending movement. 
         [0030]    This principle can be summarized as the followings: ‘the rotational force&lt;the frictional force received when the piston  200  contacts an inner wall of the container body  110  &lt;the operational force delivered for ascending/descending’. Accordingly, it is preferred that a shape and a material should be determined for the piston  200  so as to satisfy such conditions. 
         [0031]    Meanwhile, in another exemplary embodiment, just by making the cross-sectional shape of the piston  200  to a shape, which corresponds to the cross-sectional shape of an inner was of the container body  110 , into a shape, such as an oval or a polygon, it is possible that the piston  200  can make only a vertical movement inside the container body  110 , but not a rotational movement. 
         [0032]    Next, a third rotation member  500  will be described. The third rotation member  500 , as illustrated in  FIGS. 2 and 3 , is screw-coupled, fitted with the second rotation member  400 , further comprising a third screw thread  501  coupled to a second screw thread  401 . 
         [0033]    Next, a rotation conversion means  600  will be described. The rotation conversion means  600 , as illustrated in  FIGS. 2 and 3 , is coupled to the third rotation member  500  and rotates the third rotation member  500  to one side direction according to vertical movement of a button  660 . 
         [0034]    As exemplary embodiments embodying the rotation conversion means  600 , a variety of exemplary embodiments can be possible. As one of the exemplary embodiments, as illustrated in  FIGS. 2, 5 and 6 , the rotation conversion means  600  is preferred to further comprise a rotation conversion part cap  610 , an elastic member  620 , a rotation operating member  630 , a vertical motion member  640 , and a vertical guide  650 . 
         [0035]    In this case, the rotation conversion part cap  610 , as illustrated in  FIGS. 2 and 6 , has a through hole  611  formed at an upper portion thereof for the second rotation member  400  to pass through, and is configured to have the third rotation member  500  disposed at an inner portion thereof. Meanwhile, for the vertical guide  650  and the rotation conversion part cap  610  to be engaged, an engagement protrusion  612 , as illustrated in  FIGS. 2 , is preferably provided at a lower portion of the rotation conversion part cap  610 , and an engagement groove  652  is provided at an upper portion of the vertical guide  650  for the engagement protrusion  612  to be inserted and coupled. 
         [0036]    The rotation operating member  630 , as illustrated in  FIGS. 2 and 5 , is provided for being supported in a downward direction by the elastic member  620  installed at the rotation conversion part cap  610 , with a coupling protrusion  631  engaged at a coupling groove  510  which is formed at the third rotation member  500 , and with an inclined surface  632  and a flat part  633  provided in order and in repetition, as illustrated in  FIGS. 2, 5 and 6 . 
         [0037]    The vertical motion member  640 , as illustrated in  FIGS. 2 and 6 , is provided at a lower portion of the rotation operating member  630 , a bilateral inclined surface  641  is provided repeatedly at an upper end thereof, and a rotation preventing protrusion  642  is provided extending in a downward direction of the bilateral inclined surface  641  along an outer circumferential surface. 
         [0038]    Adding to a configuration illustrated in  FIGS. 2 and 6 , the vertical guide  650 , as illustrated in a dotted line in  FIG. 5  for indicating along with elements inside, is engaged to a lower portion of the rotation conversion part cap  610 , receives the elastic member  620 , the rotation operating member  630 , and the vertical motion member  640  at an interior thereof at a state of being engaged with the rotation conversion part cap  610 , is provided with a unilateral inclined protrusion part  653  repeatedly at an upper end along an lower inner circumferential surface thereof, and is provided with a vertical guide groove  651  wherein each of the rotation preventing protrusion  642  is inserted and guided at each of an unilateral inclined protrusion part  653 . 
         [0039]    The operation of the rotation conversion means  600  having a configuration in the above, referring  FIG. 6 , is described as the followings. 
         [0040]    Firstly, in an early state as illustrated in  FIG. 6( a ) , while the rotation operating member  630  is elastically being supported to a downward direction by the elastic member  620 , most portion of the inclined surface  632  is touched with the unilateral inclined protrusion part  653  in a state of the rotation operating member  630  descending, and the rotation preventing protrusion  642  connected with the button  660  is disposed inside the vertical guide groove  651  in a state of the rotation preventing protrusion  642  descending. 
         [0041]    When the button is pressurized in the state above, the vertical motion member  640  starts to ascend accordingly as illustrated in  FIG. 6( a ) . In this case, a vertical side surface  632 a connected to the inclined surface  632  and a vertical surface  632 b connected to the unilateral inclined protrusion part meet each other and prevent a rotational motion to one side direction, such that the rotation operating member  630  gets to ascend along with the vertical motion member  640  while an upper apex of the bilateral inclined surface  641  of the rotation preventing protrusion  642  is pushing up the inclined surface  632 . 
         [0042]    After that, when the button  660  is pressurized to the end as illustrated in  FIG. 6 c   , the bilateral inclined surface  641  and the unilateral inclined protrusion part  653  are connected each other. At this time, the rotation operating member  630  elastically supported to a downward direction by the elastic member  620  descends along the bilateral inclined surface  641  and the unilateral inclined protrusion part  653  which are connected with the inclined surface  632 , being rotated by an elastic force of the elastic member  620 . 
         [0043]    Lastly, even after the button  660  descends and goes back to the original position, as illustrated in  FIG. 6 d   , the rotation operating member  630 , by an elastic force of the elastic member  620 , keeps on rotating and descending along the bilateral inclined surface  641  and the unilateral inclined protrusion part  653 , and then goes back to an initial state, completing one operational cycle. 
         [0044]    Meanwhile, an ascent/descent and its rotational operation according to the rotation operating member  630  as in the above delivers only the rotational operation to the third rotation member  500  through a coupling protrusion  631  connected to a coupling groove  510  further provided at the third rotation member  500 . Through this, thus, the pressurizing the button  660 , in general, is converted to a rotational operation of the third rotation member  500 . Accordingly, it is possible to discharge contents easily with one hand by employing a button type for the contents discharge. 
         [0045]    Furthermore, for improving user convenience, a button-type pencil cosmetic dispenser, as illustrated in  FIG. 2 , is preferred to further include a discharging member  120  coupled to the discharging hole  111  and vertically provided with a movement passage  121 , and an application member  130  coupled to the movement passage  121 . 
         [0046]    Meanwhile, for user convenience, as illustrated in  FIGS. 1 and 2 , it is possible that a button-type pencil cosmetic dispenser further includes an outer container  700  which imbeds the container body  110  therein and a lower portion thereof open for the button  660  to be exposed; a finishing member  710  coupled to an upper portion of the outer container  700  and covering and fixing a lower portion of the application member  130 ; and a cover cap  720  detachably coupled to an upper portion of the outer container  700 . In this case, it is possible that the outer container  700  and the cover cap  720  can have the cross-section thereof embodied into a variety of designs such as a circle, a triangle, and a square. 
         [0047]    As described in the above, a button-type pencil cosmetic dispenser  100 , as illustrated in  FIGS. 3 and 4 , can be manufactured in a compact structure wherein a piston can be raised by adopting a configuration wherein a first rotation member  300  and a second rotation member  400  can be raised in order, such that it is possible to store more contents inside a container body.
