CROSS-REFERENCE TO RELATED APPLICATIONS 
     This U.S. non-provisional patent application is a national stage application under 35 U.S.C. §371 of international application PCT/KR2013/008811, filed Oct. 2, 2013, and claims the benefit of priority under 35 U.S.C. §119 of Korean Patent Application No. 10-2012-0109822, filed Oct. 4, 2012, the entire content of which is hereby incorporated by reference for all purposes. 
     BACKGROUND OF THE INVENTION 
     Generally, as a method for using liquid-type content such as eye cream, which is desirably used with a small amount but with exactly a fixed amount, individually packing method with as much amount as to be used each time like a capsule has been used traditionally. However, even when a user used content packed in this individually packed method, relatively a good deal of amount of content remained inside the capsule; therefore the method was considered as inefficient. 
     To solve the problem of this individually packed method, a spuit-type cosmetic container that discharges a fixed quantity to be used by means of a spuit after containing content into the container was suggested. 
     The existing spuit-type container as above has a structure, wherein a piston rod combined on the lower portion of a button part descends when the button part is pressurized, and simultaneously a piston combined on the lower portion of the piston rod descends and generates inner pressure of a spuit pipe, causing the discharge of content suctioned into the inside of the spuit pipe, and also, because the piston rod is composed to descend perpendicularly, virtual pressure is delivered exactly so to the piston which generates the inner pressure powerfully and causes a sudden discharge of the content; therefore, it leads to a problem that it is not easy for a user to apply content exactly on the wanted area, and thereby causes inconvenience for the user.

     Referring to  FIGS. 1 to 4 , an explanatory view illustrating according to an exemplary embodiment includes a container body  100 , a spuit pipe  200 , an applicator  300 , an inner cap  400 , an ascending and descending member  500 , a button part  600 , and an outer cap  700 . 
     The said container body  100  holding contents comprises a coupling part  110  which equips a first screw thread  111 , encircling the outer circumferential surface so that the inner cap  400 , which will be described later, is coupled. 
     The said spuit pipe  200  suctions content contained in the container body  100 , and it is preferable that on the upper end of the spuit pipe  200  is provided a securing part  210  which secures on the upper end of the coupling part  110  of the container body  100 , and on the lower end of the securing part  210  is provided a gasket  220  which prevents content held in the container body  100  from being discharged and prevents the spuit pipe  200  from being broken. 
     The applicator  300  is coupled to the lower portion of the spuit pipe  200  and discharges content, comprising a steel ball  310  which is contacted on a user&#39;s skin and discharges content by rotation, a ball support body  320  which is coupled to the lower portion of the spuit pipe  200  and forms a space for rotation of the steel ball  310 , and a ball cap  330  which is coupled to the end of the ball support body  320  and prevents separation of the steel ball  310 . 
     The inner cap  400 , which is coupled with screw coupling to the coupling part  110  of the container body  100  and guides ascending and descending the ascending and descending guide member  500 , comprises a body  410  and an ascending and descending guide part  420 . 
     The body  410 , encircling the coupling part  110  of the container body  100  and coupled with screw coupling, comprises a 2nd screw thread  411  which is coupled with the first screw thread  111  on the inner circumferential surface. 
     In various embodiments, it is featured that on both inner circumferential surfaces are provided a pair of depression grooves  412  which are depressed to inner surface direction. The depression parts  412 , on which a rotation protrusion  730  to be described is provided, limit rotation range of an outer cap  700  by means of both ends of the depression parts  412  when the outer cap  700  rotates. 
     The depression parts  412  form a space for independent rotation of the outer cap  300  when the outer cap  300  rotates under the state of the inner cap  400  being couples to the container body  100 , thereby causing ascent of the ascending and descending member  500  that will be described later. 
     On the other hand, it is preferable that on the outer circumferential surface of the body  400  is provided a coupling protrusion  413  which encircles the outer circumferential surface so as to make coupling with the outer cap  700  possible. 
     The ascending and descending guide part  420  form a tubular shape which extends to the upper part on the upper end of the body  410 , and in at least some of the presently described embodiments, it is featured that a pair of spiral grooves  421  are provided to guide ascending and descending the ascending and descending member  500  on both outer circumferential surfaces of the ascending and descending guide part  420 . 
     The spiral grooves  421  guides guide protrusions  520  to move along the spiral grooves  421  when the ascending and descending member  500  descends by a button part  600  pressurizing, thus controlling descending speed of the ascending and descending member  500  and thereby preventing content from being discharged rapidly. 
     The ascending and descending member  500  which is coupled to the button part  600  and ascends and descends inside the inner cap  400  according to the ascending and descending operation, thus changing the pressure in the spuit pipe  200  and inducing the content to be suctioned or discharged, includes a piston rod  510  and guide protrusions  520 . 
     The piston rod  510  is coupled to a button  610  and ascends and descends according to the ascending and descending operation of the button  610 , wherein on the lower portion of the piston pipe  510  is coupled a piston  511  which ascends and descends as being contacted tightly to the inner wall of the inner cap  400 , and changes the pressure in the spuit pipe  200  and thus induces content to be suctioned and discharged. 
     The guide protrusions  520  are provided with protrusion on both outer circumferential surfaces, wherein it is featured that in the present invention, the guide protrusion  520  are composed to move along the spiral grooves  421  of the inner cap  400 . 
     The guide protrusions  520  move along the spiral grooves  421 , control descending speed when the ascending and descending member  500  descends according to pressurization of the button part  600 , and thereby minimizes pressure generated by the piston  511  and prevents content from being discharged rapidly. 
     The button part  600  is coupled to the upper portion of the ascending and descending member  500  and delivers pressure caused by a user&#39;s pressurizing to the ascending and descending member  500 , comprising a button  610  which is coupled to the upper portion of the piston rod  510  and a button cap  620  which is coupled to a hollow cavity of the outer cap  700  that will be described later and delivers pressure to the button  610  by encircling the button  610  and provided to the button  620 . 
     The outer cap  700  is coupled to be able to rotate, encircling the inner cap, also comprising a hollow cavity  710  for the button cap  620  to be coupled and a coupling groove  740  which is coupled to the coupling protrusion  413  of the inner cap  400  on the inner circumferential surface. 
     In this present embodiments, it is featured that a perpendicular guide groove  720  is provided on the inner circumferential surface of the outer cap  700  where the guide protrusion  520  is inserted for the guide protrusion  520  to move perpendicularly, wherein the perpendicular guide groove  720  guides the guide protrusion  520  to move along the spiral grooves  421  when the outer cap  700  rotates independently. 
     On the other hand, it is featured that on the inner surface of the outer cap  700  are provided a pair of rotation protrusions, wherein the pair of rotation protrusions are secured on both end of the depression parts when the outer cap  700  rotates, thus limiting independent rotation range of the outer cap  700 ; meanwhile, when secured on both ends of the depression parts, the pair of rotation protrusions guide the inner cap  400  to be rotated with the outer cap  700  together. 
     In the following, referring to  FIG. 5  and  FIG. 6 , a method of use of a spuit-type cosmetic container according to an exemplary embodiment is explained. 
       FIG. 5  and  FIG. 6  are explanatory views illustrating a method of use of a spuit-type cosmetic container according to an exemplary embodiment. Referring  FIG. 5  and  FIG. 6 , a spuit-type cosmetic container according to an exemplary embodiment of the present invention has a structure, wherein in a state that the inner cap  400  and the outer cap  700  are coupled on the upper portion of the container body  100 , if a user rotates the outer cap  700  to one side until the rotation protrusion  730  located on one end of the depression part  412  gets to be secured on the other end of the depression part  412 , rotation of the outer cap  700  is performed. As shown above, when independent rotation of the outer cap  700  is performed, the guide protrusion  520  of the ascending and descending member  500  inserted into the perpendicular guide groove  720  of the outer cap  700  ascends along the spiral grooves  421  of the inner cap  400  and thereby leads to the ascent of the piston  500  with the ascending and descending member  500  moving together. 
     As show above, when the piston  500  ascends, content is suctioned to the inside of the spuit pipe  200  by its pressure; at this time, the button part  600  coupled on the upper portion of the ascending and descending member  500  moves upwards as the ascending and descending member  500  ascends. 
     Next, after the independent rotation of the outer cap  700  is performed, that is to say, when rotation protrusions  730  which has been located on one end of the depression parts  412  is secured on the other end of the depression parts  412 , whereafter the rotation of the inner cap  400  is performed with the rotation of the outer cap  700 , and thereby the inner cap  400  and the outer cap  700  are separated, thus leading to separation of the inner cap  400  from the outer cap  700   
     After a user grips the outer cap  700  and separates the inner cap  400  from the container body  100 , it is possible to use content discharged through the applicator  300  by pressurizing the button part  600 . At this time, when the button part  600  is pressurized, it is possible to limit descending speed of the ascending and descending member  500  not by making the ascending and descending member  500  descend perpendicularly directly, but by making the guide protrusion rotate along the spiral grooves and descend. Therefore, it is possible to minimize the pressure generated by the piston  511  and prevent content held in the spuit pipe  200  from being discharged rapidly, thereby making it possible to apply content exactly on desired area through the applicator part  300 .
