Full Description:
BACKGROUND OF THE INVENTION 
       [0001]    The present invention disclosed herein relates to a liquid lipstick container, wherein a liquid lipstick container has a configuration in which an ascending/descending guide member is rotated together when a user rotates a container body while gripping a support body, such that a pumping guide member is lifted up/lowered, thereby performing a pumping operation. Thus, liquid contents are discharged through a simple structure, which improves usability when contents are applied through an applicator at an upper portion of the container. 
         [0002]    Generally, a solid lipstick is configured to lift/lower a solid stick to the outside of a container by rotating a lower portion of the container after opening a cover thereof. For example, when using a lipstick, a user first opens the cover of a container, protrudes the stick out by rotating a lower portion thereof, and lowers the stick to be received into the container after using. 
         [0003]    However, this type of solid lipstick has a problem wherein its ingredients are easily spoiled by contact with outside air. 
         [0004]    In addition, another type of lipstick, which is used by spreading a liquid lipstick onto a brush like spreading a nail polish, also has a problem of hardening easily by contact with outside air. 
         [0005]    To solve the problems as the above, “liquid lipstick container” is disclosed in the registered utility model patent no. 20-0367724 (hereafter called as the registered utility model patent). 
         [0006]    The registered utility model patent relates to a liquid lipstick container, the liquid lipstick container comprising: a liquid lipstick receiving tube ( 10 ) receiving a liquid lipstick; a piston ( 20 ) pressurizing the liquid lipstick received in the liquid lipstick receiving tube; a piston rod ( 30 ) pushing the piston ( 20 ) and pressurizing a liquid lipstick (M); an operation housing ( 40 ) operating the piston rod ( 30 ); a brush supporting cap ( 50 ) supporting a lipstick brush ( 51 ); and a cap ( 20 ) sealing the lipstick brush ( 51 ), 
         [0007]    wherein the liquid lipstick receiving tube ( 10 ) is characterized to be equipped with a pair of elastic leg parts ( 11 ) having a screw part ( 13 ) at an inner side of a lower end thereof and an outward protrusion ( 12 ) at an outer side end thereof, wherein the piston rod ( 30 ) comprises a screw part ( 32 ) screw-coupled to the elastic leg part ( 11 ) and an operating protrusion ( 33 ) at a lower end thereof, wherein the operation housing ( 40 ) is characterized to comprise an operating rib ( 41 ) at an interior so as to push the operating protrusion ( 33 ). 
         [0008]    The registered utility has a structure wherein as a piston rod ( 30 ) ascends by the rotation of the rotation of an operation housing ( 40 ), a piston ( 20 ) coupled with a globular protrusion ( 31 ) at an upper end of a piston rod ( 30 ) moves in an upward direction and discharges liquid contents by squeezing. To squeeze contents out, the lipstick container should be equipped with an operating rib ( 41 ), an operating protrusion ( 33 ), a pair of elastic leg parts ( 11 ); therefore, the structure of the lipstick container becomes complicated, thereby resulting in a problem a complicated assembly process and a high manufacturing cost. 
         [0009]    In addition, a space for the length of a piston rod ( 30 ) should be secured; therefore, the lipstick container gets bigger in size, thereby resulting in a problem of not being easy to carry.

     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS 
       [0025]    Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. The same reference numerals provided in the drawings indicate the same members. 
         [0026]      FIG. 1  is an exploded perspective view illustrating a configuration of a liquid lipstick container according to an exemplary embodiment of the present invention.  FIG. 2  is an assembled perspective view illustrating a configuration of a liquid lipstick container according to an exemplary embodiment of the present invention.  FIG. 3  is a cross-sectional view illustrating a configuration of a liquid lipstick container according to an exemplary embodiment of the present invention. 
         [0027]    Referring to  FIGS. 1 to 3 , a liquid lipstick container according to an exemplary embodiment of the present invention may include a container body  100 , an ascending/descending guide member  200 , a pumping guide member  300 , a support body  400 , and an applicator  500 . 
         [0028]    The container body  100  storing liquid contents is configured to have a volume getting reduced according to a use of the contents, and simply saying, the container body  100  may equip a piston  110  which ascends according to a use of the contents inside of the content body  100 . Additionally, it is possible that the container body  100  has a configuration wherein an inner container made of soft material that is absorbed according to a use of contents can be coupled separately inside the container body  100 . 
         [0029]    In the present invention, it is characterized that the container body  100  is configured to be rotated in a state that a support body  400  to be described later is gripped. When a user rotates the container body  100 , a pumping guide member  300  can be ascended/descended by rotating an ascending/descending guide member  200  together which is coupled at an upper portion of the container body  100 . 
         [0030]    Meanwhile, at an upper portion of the container body  100  is coupled an over cap  800  which encases the support body  400  and the applicator  500  so as to prevent the support body  400  and the applicator  500  from being broken by a foreign material flowing through a discharging hole  511  or by an external pressure. 
         [0031]    The ascending/descending guide member  200 , coupled to an upper portion of the container body  100  and rotating together when the container body  100  rotates, is equipped with a content inflow part  210  forming a content inflow hole  211  at an inner center portion thereof such that the contents stored in the container body  100  can flow in. At the content inflow part  210  is equipped a first check valve  212  which is installed at an upper portion of the content inflow hole  211  and opens/closes the content inflow hole  211  according to a pressure change of the content inflow part  210 . 
         [0032]    Furthermore, at the content inflow part  210  is coupled a sealing member  700  which seals a space separated between the content inflow part  210  and a content suction tube  320  to be described later. An outer circumferential surface of the sealing member  700  is closely contacted to the content inflow part  210  and an inner circumferential surface thereof is closely contacted to the content suction tube  320 , such that the sealing member  700  seals the space separated between the content inflow part  210  and the content suction tube  320 . 
         [0033]    In the present invention, it is characterized that at an upper portion of the ascending/descending guide member  200  is equipped an ascending/descending guide protrusion  220  which ascends/descends a pumping guide member  300  to be described later by rotation of the ascending/descending guide member, wherein a pair of ascending/descending guide protrusions  220  are protrusively formed alternately above and below along the perimeter of an upper end of the ascending/descending guide member  200  and guides a movement of a pumping guide protrusion  310 . When the pumping guide protrusion  310  moves form a bottom dead point  312  of the ascending/descending guide protrusion  220  to a top dead point  311  thereof, the pumping guide member  300  ascends, whereas when the pumping guide protrusion  310  moves from a top dead point  311  of the ascending/descending guide protrusion  220  to a bottom dead point  312  thereof, the pumping guide member  300  descends, thereby achieving an ascent/descent of the pumping guide member  300 . 
         [0034]    Meanwhile, it is possible that the ascending/descending guide protrusion  220  can be configured in a way that the container body  100  can be rotated to both directions. However, it is preferable to be rotated to one direction for operational stability e.g. not to easily discharge contents by rotating the content body  100  by an external pressure during the period of storing or not to store contents with a check valve opened. For this purpose, at both sides of the bottom dead point of the ascending/descending guide protrusion  220  is formed a protrusion  221  for preventing a reverse rotation of the container body  100 . 
         [0035]    The pumping guide member  300  ascended/descended by the rotation of the ascending/descending guide member  200  changes an internal pressure of the content inflow part  210  and induces a pumping operation, further comprising a pumping guide protrusion  310 , a content suction tube  320 , and a valve installation part  330 . 
         [0036]    A pair of the pumping guide protrusions  310  protrusively formed at both sides of the pumping guide member  300  are secured at an upper end of the ascending/descending guide protrusion  220 , and move along an upper side face of the ascending/descending guide protrusion  220  when ascending/descending guide member rotates. At this time, the pumping guide protrusion  310  can be inserted to a vertical guide groove  420  formed at an inner side of the support body  400  and move vertically. 
         [0037]    The content suction tube  320 , which ascends together as the pumping guide protrusion  310  ascends and sucks the contents stored in the container body  100  by changing an internal pressure of the content inflow part  210 , has a tube shape with an inner part empty such that contents can move through. 
         [0038]    The content suction tube  320 , which ascends/descends in a state that an outer circumferential surface thereof is closely contacted to the sealing member  700  and makes it possible for a first check valve  212  to open/close a content inflow hole  211  by changing an internal pressure of the content inflow part  210 , pressurizes an upper end of the first check valve  212  in a state that the pumping guide member  300  is descended and thereby prevents the first check valve  212  from being opened. 
         [0039]    The valve installation part  330  forms a space which stores contents moving to an upper portion thereof through the content suction tube  320  and has a second check valve  331  installed so as to open/close an opened upper end of the content suction tube  320 , wherein the second check valve  331  closes the open upper end of the content suction tube  320  when the pumping guide member  300  ascends, whereas the second check valve  331  opens an open upper end of the content suction tube  320  by the pressure of contents when the pumping guide member  300  descends. 
         [0040]    Meanwhile, at an upper portion of the pumping guide member  300  are installed a content moving part  600  which connects the pumping guide member  300  and an applicator  500  such that contents flowing in the valve installation part  330  can move to the applicator  500 . The content moving part  600  comprises a coupling part  610  which is coupled to an upper portion of the pumping guide member  300 , and a content moving tube  620  which extends from the coupling part  610  and is coupled to a discharging tube  520  of the applicator  500  so as to be ascended/descended and forms a space where contents moves. 
         [0041]    The content moving part  600  equips a hollow such that the contents flowing into the valve installation part  330  can move to the applicator  500 . 
         [0042]    Furthermore, at an upper portion of the pumping guide member  300  is equipped a spring (S) which is disposed encasing the content moving part  600  at an outer side of the content moving part  600 , and provides an elastic force to a downward direction during the process when the pumping guide protrusion  310  moves from a top dead point  311  of the ascending/descending guide protrusion  220  to a bottom dead point  312  thereof and causes the pumping guide member  300  to descend. A lower end of the spring (S) is secured to an upper portion of the pumping guide member  300  while an upper end thereof is supported by an upper inner side of the support body  400 , such that the spring (S) contracts when the pumping guide protrusion  310  ascends along an upper side face of the ascending/descending guide protrusion  220 , and stretches when the pumping guide protrusion  310  descends along an upper side surface of the ascending/descending guide protrusion  220 , thereby providing an elastic force to the pumping guide member  300 . 
         [0043]    The support body  400 , which is coupled at an upper portion of the container body  100 , encasing the ascending/descending guide member  200  and the pumping guide member  300 , forms a hollow  410  at an upper portion thereof such that the applicator  500  can be coupled and a vertical guide groove  420  which guides a vertical movement of the pumping guide protrusion  310 . 
         [0044]    The applicator  500 , which is coupled to the hollow  410  of the support body  400  and applies contents to a user&#39;s lips, comprises an application surface  510 , wherein the application surface  510  has a discharging hole  511  at a center portion thereof such that contents can be discharged through. 
         [0045]    Furthermore, at an inner upper side of the applicator  500  is equipped a discharging tube  520  which extends to a downward direction such that the content moving tube  620  of the content moving part  600  can be coupled so as to ascend/descend. 
         [0046]    Hereinafter, referring  FIGS. 4 to 6 , an operational process of a liquid lipstick container according to an exemplary embodiment of the present invention will be explained.  FIGS. 4 to 6  are views illustrating an operational state of a liquid lipstick container according to an exemplary embodiment of the present invention.  FIG. 7( a )  to  FIG. 7( c )  is a view illustrating a process wherein a pumping guide protrusion is ascended/descended by an ascending/descending guide protrusion according to an exemplary embodiment of the present invention. 
         [0047]    Referring  FIG. 4  through  FIG. 7( c ) , when a user rotates a container body  100  while gripping a support body  400 , an ascending/descending guide member  200  coupled to an upper portion of the container body  100  rotates together. Due to this, a pumping guide protrusion  310  which is secured at an upper side surface of an ascending/descending guide protrusion  220  of the ascending/descending guide member  200  moves along the upper side surface of the ascending/descending guide protrusion  220  and changes in height, such that the pumping guide member  300  is ascended/descended. As shown in  FIG. 7( a )  to  FIG. 7( c ) , when the pumping guide protrusion  310  moves form a bottom dead point  312  of the ascending/descending guide protrusion  220  to a top dead point  311  thereof, the pumping guide member  300  ascends, whereas the pumping guide member  300  descends when the pumping guide protrusion  310  moves from the top dead point  311  of the ascending/descending guide protrusion  220  to a bottom dead point  312  thereof; therefore, the pumping guide member  300  is able to perform ascending/descending. 
         [0048]    Meanwhile, shown in  FIG. 5 , when the pumping guide member  300  ascends, an internal pressure of the content inflow part  210  is changed by an ascent of the content suction tube  320  and causes a first check valve  212  to open a content inflow hole  211 . This makes the contents stored in the container body  100  flow into the content inflow part  210  through the content inflow hole  211 . At this time, a second check valve  331  installed at a valve installation part  330  keeps an open upper part of the content suction tube  320  closed. As the pumping guide member  300  ascends, part of the contents stored in the valve installation part  330 , a content moving part  600 , and a discharging tube  520  is discharged through a discharging hole  511  of the applicator  500 . 
         [0049]    Next, as shown in  FIG. 6 , when the pumping guide member  300  descends, an internal pressure of the content inflow part  210  changes by a descent of the content suction tube  320 , and then causes a first check valve to close the content inflow hole  211 . At this time, a lower end of the content suction tube  320  pressurizes an upper end of the first check valve  212 , prevents the content inflow hole  211  from being opened. 
         [0050]    At this time, the second check valve  331  installed at the valve installation part  330  by a pressure of the contents sucked into the content suction tube  320  opens an open upper portion of the content suction tube  320 , such that the contents sucked into the content suction tube  320  through the open upper portion of the content suction tube  320  move to the valve installation part  330 , the content moving part  600 , and the discharging tube  520 . 
         [0051]    As described in the above, the present invention is configured to discharge contents by a pumping operation according to the ascent/descent of a pumping guide member  300  when a container body  100  rotates and to apply contents to lips by means of an applicator  500 ; thus it is possible to apply liquid contents onto lips and do a lip make-up in the same way of a conventional stick-type lipstick. 
         [0052]    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. Therefore, those skilled in the art will appreciate that various modifications and other equivalent embodiments are possible from the above embodiments.
