Title: Lipstick case

Description:
BACKGROUND OF THE INVENTION 
     The present invention disclosed herein relates to a lipstick case, and more particularly, to a lipstick case having a structure wherein a lipstick is exposed outwards when lowering an ascending and descending member which encases the lipstick as rotating a rotation body to one side direction, whereas the lipstick is hidden by the ascending and descending member when the rotation body is rotated to the other side direction and thereby the ascending and descending member ascends. Therefore, it is possible to fundamentally prevent problems in use, e.g. a lipstick breakage caused by closing a cover part in a state of the lipstick being ascended. 
     Generally, a solid lipstick has a structure wherein a solid-type stick can be ascended and descended out of a container by rotating a rotation body provided at a lower portion of the container after opening a cover. For example, to use a lipstick, a user should open a cover of the container first, rotate a rotation body, and ascend it to expose the stick outwards. After using, the user should lower the stick to make the stick received inside of the container. 
     “A lipstick case” having the same structure as the above is disclosed in FIG. 1 of Korean Registered Utility Model No. 20-0241614 (Hereafter, it will be referred as ‘the registered utility model’). 
     The registered utility model has a structure wherein as a lipstick (2) is interlocked to a lipstick holder (3), a fixing protrusion (4) of a lipstick holder (3) is interlocked to a spiral groove (6) formed at an inner portion of a rotating tube (5), and thereby the lipstick holder is coupled to the rotating tube (5). A guiding tube (7) is inserted between the lipstick holder (3) and the rotating tube (5) and fitted with the rotating tube (5) by a spiral protrusion (9) with a fitted combination. Meanwhile, the fixing protrusion (4) of the lipstick holder (3) is disposed inside of a guide groove (8) of a guide tube (7) and at the same time disposed at a spiral groove (6). 
     However, the registered utility model has a structure wherein when the rotating tube (5) is rotated by grabbing the guide tube (7) with a hand, the fixing protrusion (4) hung between the spiral groove (6) and the guide groove (8) is ascended along with a lipstick (2) fitted to the lipstick holder (3), such that the lipstick (2) can be applied. However, in case a cover is closed in a state of the lipstick (2) being ascended, an upper end of the lipstick (2) is smashed, which may lead to the breakage of the lipstick (2). 
     Furthermore, to check a residual amount of the lipstick (2), the lipstick (2) should be ascended all the way to the end thereof, which may cause user&#39;s inconvenience. 
     SUMMARY OF THE INVENTION 
     The present invention is devised to solve such problems described in the above, and the objectives thereof are to provide a lipstick case having a structure wherein a lipstick is exposed outwards when lowering an ascending and descending member which is encasing the lipstick as rotating a rotation body to one side direction, whereas the lipstick is hidden by the ascending and descending member when rotating the rotation body to the other side direction and thereby ascending the ascending and descending member. Therefore, it is possible to fundamentally prevent problems in use, such as a problem that a lipstick is damaged by closing a cover part in a state of the lipstick being ascended. 
     Furthermore, it is possible to intuitively check the residual amount of the lipstick according to a height of a lipstick receiving tube, and it will bring user&#39;s convenience.

     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS 
     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. 
       FIG. 1  is an exploded perspective view illustrating a configuration of a lipstick case according to an exemplary embodiment of the present invention.  FIG. 2  is an assembled perspective view illustrating a configuration of a lipstick case according to an exemplary embodiment of the present invention.  FIG. 3  is a combined cross-sectional view illustrating a configuration of a lipstick case according to an exemplary embodiment of the present invention. 
     Referring to  FIGS. 1 to 3 , a lipstick case according to an exemplary embodiment of the present invention includes a lipstick holder  100 , a rotation body  200 , an ascending and descending member  300 , an ascending and descending guide member  400 , and a cover part  500 . 
     The lipstick holder  100  is loaded with a lipstick (L) at an upper part thereof and supports the lipstick (L), comprising a coupling part  110  at a lower portion thereof so as to be coupled with a fixing body  210  of a rotation body  200  to be described later. 
     The rotation body  200  is coupled to a coupling part  110  of the lipstick holder  100  at a lower portion of the lipstick holder  100  and fixes the lipstick holder  100 , and thereby ascends and descends an ascending and descending member  300  by a rotation according to a user&#39;s control. In the present invention, it is characterized that at the rotation body  200  is provided a fixing body  210  which is formed protrusively to an upper direction from a center portion of a lower end thereof such that the fixing body  210  can be coupled to a coupling part  110  and fix the lipstick holder  100 . 
     The fixing body is coupled to the coupling part  110  and supports the lipstick holder  100 , such that it is possible to keep the lipstick (L) in a fixed state all the time without changing the position of the lipstick (L). 
     Furthermore, at an inner circumferential surface of the rotation body  200  is provided a first screw thread  220  which is coupled with a second screw thread  311  of the ascending and descending member  300  to be described later and guides the ascending and descending member  300  to ascend and descend. When the rotation body  200  is rotated to one side direction, the second screw thread  311  descends along the first screw thread  220  and thereby the ascending and descending member  300  descends, whereas when the rotation body  200  is rotated to the other side direction, the second screw thread  311  ascends along the first screw thread and thereby the ascending and descending member  300  ascends. 
     Meanwhile, the rotation body  200  comprises a coupling protrusion  230  coupled with a coupling groove  410  of the ascending and descending guide member  400  at an inner side thereof so as to be rotated along with the ascending and descending guide member  400 . 
     Furthermore, a securing protrusion  240  is provided at an upper portion of the first screw thread  220  at an inner side of the rotation body  200  such that the ascending and descending guide member  400  can be secured. 
     The ascending and descending member  300  which is ascended and descended by a rotation of the rotation body  200  includes a guide tube  310  and a lipstick receiving tube  320 . 
     The guide tube  310  has a tubular shape which has an inner space such that the fixing body  210  can be inserted and comprises a second screw thread  311  at an outer circumferential surface so as to be coupled with the first screw thread  220  in a screw coupling, wherein the ascending and descending member  300  can ascend or descend as the first screw thread  220  forms a screw coupling through the second screw thread  311 . 
     Meanwhile, the guide tube is configured to have a shape that corresponds to the shape of a penetrating hole  420  which has an oval shape such that the ascending and descending member  300  can be prevented from being rotated when the rotation body  200  rotates and move vertically. It is preferred that the guide tube  310  has a cross-sectional plane on both sides thereof so as to have a corresponding shape with the penetrating hole  420  having an oval shape. 
     The lipstick receiving tube  320  which extends from the guide tube  310  to an upper portion thereof and receives the lipstick (L) and the lipstick holder  100 . In this present invention, it is characterized that the lipstick receiving tube  320  is configured to receive the lipstick (L) or expose the lipstick (L) to the outside according to the ascent and descent of the ascending and descending member  300 . 
     The lipstick receiving tube  320  is configured to expose the lipstick (L) to the outside when a guide tube  310  descends according to a rotation of the rotation body  200  to one side direction, whereas the lipstick receiving tube  320  encases and receives the lipstick (L) when the guide tube  310  ascends according to the rotation of the rotation body  200  to the other side direction. It does not have a structure where the lipstick (L) ascends and is exposed outwards from the lipstick receiving tube as in an existing lipstick, rather has a structure where the lipstick receiving tube  320  receives the lipstick or exposes the lipstick outwards by ascending and descending in a state that the position of the lipstick (L) and the lipstick holder  100  is not changed. Therefore, it is possible to fundamentally prevent problems in use, such as a problem that a lipstick is damaged by closing a cover part in a state of the lipstick being ascended. 
     Furthermore, the lipstick receiving tube  320  ascends the lipstick (L) to match the height of the lipstick (L) when the height of the lipstick (L) is lowered according to usage of the lipstick, which makes it possible to easily check the remaining amount of the lipstick (L) by seeing the height of the lipstick receiving tube  320 . 
     Meanwhile, at an inner side of the ascending and descending member  300  is provided a limiting protrusion  330  which meets a lower end of the lipstick receiving holder  100  and limits the ascent of the ascending and descending member  300  during an ascending process of the ascending and descending member  300 . 
     The ascending and descending guide member  400  is secured to a securing protrusion  240  which is secured at an inner side of the rotation body  200  and is protrusively coupled to the rotation body  200 , further comprising a coupling groove  410  which is coupled to a coupling protrusion  230  of the rotation body  200  at an outer circumferential surface thereof. 
     In the present invention, it is characteristic that at the ascending and descending member  300  is provided a rotation preventing means which prevents the rotation of the ascending and descending member  300  and guides the vertical movement of the ascending and descending member  300 , wherein the rotation preventing means comprises a penetrating hole  420  which is formed at a lower end of the ascending and descending guide member  400  such that the ascending and descending member  300  can penetrate therein, ascending and descending. The penetrating hole  420  can be composed of an oval shape in order to prevent the rotation of the guide tube  310 . In this case, the guide tube  310  is preferred to have a cross-sectional plane  312  which corresponds to the shape of the penetrating hole  420  such that the guide tube  310  can move vertically without rotating. 
     In drawings of the present invention, the shape of the penetrating hole  420  is drawn as an oval shape; however, a variety of shapes which can guide the vertical movement of the guide tube  310  without being are possible to be configured. 
     The cover part  500  is coupled detachably to the ascending and descending guide member  400 , encasing the lipstick (L) and the lipstick receiving tube  320 , and prevents contamination of the lipstick (L), e.g., getting foreign matter on the lipstick (L), by closing an opened upper end of the lipstick receiving tube  320 . 
     Hereinafter, referring  FIG. 4 , an operational method of a lipstick case according to an exemplary embodiment of the present invention will be described.  FIG. 4  is a view illustrating an operational state of a lipstick case according to an exemplary embodiment of the present invention. 
     Referring  FIG. 4 , when a user rotates the rotation body  200  to one side direction after pressurizing the ascending and descending guide member  400  with one hand in a state that the lipstick receiving tube  320  of the ascending and descending member  300  encases and receives the lipstick (L), the guide tube  310  is descended by the screw coupling of a first screw thread  220  of the rotation body  200  and a second screw thread  311  of the guide tube  310 . Due to this, the lipstick receiving tube  320  which is combined integrally to an upper portion of the guide tube  310  descends along, such that the lipstick (L) is exposed to the outside. 
     At this time, the guide tube  310  is preferred to be configured to have a shape which corresponds to the shape of a penetrating hold  420  of the ascending and descending guide member  400 . 
     As the above, when a user rotates the rotation body  200  to the other side direction after pressurizing the ascending and descending guide member  400  with one hand in a state that the lipstick (L) is exposed to the outside as the lipstick receiving tube  320  descends, the guide tube  310  is ascended by a screw coupling of a first screw thread  220  of the rotation body  200  and a second screw thread  311  of the guide tube  310 . Due to this, the lipstick receiving tube  320  which is combined integrally to an upper portion of the guide tube  310  ascends along, and thereby receives the lipstick (L). 
     A lipstick case according to another exemplary embodiment of the present invention is configured to guide a vertical movement of the ascending and descending member  300  through a penetrating hole  420  which has an oval shape and is formed at a lower end of the ascending and descending guide member  400 . A lipstick (L) is configured to be disposed fixedly all the time, either being exposed to the outside or being received in the lipstick receiving tube  320 . Therefore, it is possible to fundamentally prevent problems caused by the structure of the existing lipsticks in which a lipstick itself ascends and descends, e.g. a breakage of a lipstick caused when closing a cover part in a state of the lipstick being ascended. 
     Hereinafter, with reference to  FIGS. 5 and 7 , a lipstick case according to another exemplary embodiment of the present invention will be described in detail.  FIG. 5  is an exploded perspective view illustrating a configuration of a lipstick case according to another exemplary embodiment of the present invention.  FIG. 6  is an assembled perspective view illustrating a configuration of a lipstick case according to another exemplary embodiment of the present invention.  FIG. 7  is a combined cross-sectional view illustrating a configuration of a lipstick case according to another exemplary embodiment of the present invention. 
     Referring  FIGS. 5 to 7 , a lipstick case according to another exemplary embodiment of the present invention includes an ascending and descending guide member  400  rotatably coupled at an outer side of a rotation body  200 . In the present invention, it is characteristic that a rotation preventing means is equipped at an upper portion of the ascending and descending guide member  400  such that the rotation preventing means can prevent a rotation of the ascending and descending member  300  when the rotation body  200  rotates, and guides the ascending and descending member  300  to move vertically. 
     The rotation preventing means according to another exemplary embodiment of the present invention is configured to have a rotation guiding part  430  of a square shape such that the rotation preventing means is disposed at an upper portion of the ascending and descending guide member  400  and prevents a rotation of the lipstick receiving tube  320 . In this case, the lipstick receiving tube  320  is preferred to have a shape which corresponds to the shape of the rotation guiding part  430  such that the lipstick receiving tube  320  is not rotated but is guided to move vertically. 
     Meanwhile, generally the rotation guiding part  430  is preferred to have a shape with all corners rounded in order to give a similar feeling with the shape of a tubular lipstick. 
     In drawings of the present invention, the shape of the rotation guiding part  430  is drawn as a square shape; however, a variety of shapes which can guide the vertical movement of the guide tube  310  without being are possible to be configured. 
     Meanwhile, a protrusion  440  is provided at an inner side of the ascending and descending guide member  400  so as to meet an upper end of the limiting protrusion  330  and limit the ascent of the ascending and descending member  300  in a process that the ascending and descending member  300  is ascending. 
     Detailed explanations of the rest structures according to another exemplary embodiment of the present invention are omitted because they are the same with the structures according to an exemplary embodiment of the present invention. 
     Hereafter, referring  FIG. 8 , the method of use of a lipstick case according to an exemplary embodiment of the present invention will be described.  FIG. 8  is a view illustrating an operational state of a lipstick case according to another exemplary embodiment of the present invention. 
     Referring  FIG. 8 , when a user rotates the rotation body  200  to one side direction after pressurizing the ascending and descending guide member  400  with one hand in a state that the lipstick receiving tube  320  of the ascending and descending member  300  encases and receives the lipstick (L), the guide tube  310  descends by a screw coupling of a first screw thread  220  of the rotation body  200  and a second screw thread  311  of the guide tube  310 . Due to this, the lipstick receiving tube  320  which is combined integrally to an upper portion of the guide tube  310  descends along with the lipstick receiving tube  320 , such that the lipstick (L) is exposed to the outside. 
     At this time, it is preferred that the lipstick receiving tube  320  has a shape which corresponds to the shape of the rotation guiding member  430  of the ascending and descending guide member  400  so as to move vertically without being rotated. 
     As the above, when a user rotates the rotation body  200  to the other side direction after pressurizing the ascending and descending guide member  400  with one hand in a state that the lipstick (L) is exposed to the outside as the lipstick receiving tube  320  descends, the guide tube  310  is ascended by a screw coupling of a first screw thread  220  of the rotation body  200  and a second screw thread  311  of the guide tube  310 . Due to this, the lipstick receiving tube  320  which is combined integrally to an upper portion of the guide tube  310  ascends along, and thereby receives the lipstick (L). 
     A lipstick case according to another exemplary embodiment of the present invention is configured to guide a vertical movement of the ascending and descending member  300  through a rotation guiding part  430  which has a square shape and is formed at an upper portion of the ascending and descending guide member  400 . A lipstick (L), the same as an exemplary embodiment of the present invention, is configured to be disposed fixedly all the time, either being exposed to the outside or being received in the lipstick receiving tube  320  by ascent and descent of the ascending and descending member  300 . Therefore, it is possible to fundamentally prevent problems caused by the structure of existing lipsticks in which a lipstick itself ascends and descends, e.g., a breakage of a lipstick caused when closing a cover part in a state of the lipstick being ascended.
