     TECHNICAL FIELD 
       [0002]    The following disclosure relates to a tube-type cosmetic container which discharges a liquid content in a form of droplet, and more particularly, to a tube-type cosmetic container which can reduce the cost burden in accordance with shortening of the manufacturing time and reducing cost, by allowing a liquid content to be discharged in a form of droplet through a simple content discharging structure that becomes gradually wider from a lower portion to an upper portion thereof. 
       BACKGROUND 
       [0003]    Generally, liquid medicine and artificial tears which are dripped in the eyes for use are contained in a tube-type container and are provided. When a user pressurizes the tube-type container, liquid contents are uniformly discharged in a form of droplet. 
         [0004]    For example, a tube-type cosmetic container for discharging a liquid content in a form of droplet is disclosed in Korean Utility Model No. 20-0310084 (hereinafter, referred to as “Korean Utility Model”). 
         [0005]    Korean Utility Model relates to a tube-type cosmetic container in which a discharge port coupling cap ( 3 ) having a discharge hole ( 3   a ) is coupled to a discharge port ( 2 ) formed on the front end of a tube container ( 1 ), and a cap ( 4 ) is disposed on and coupled to the discharge port coupling cap ( 3 ). Also, a first discharge tube ( 5 ) having a discharge hole ( 5   a ) is inserted into the discharge port coupling cap ( 3 ), and an intermediate outlet tube ( 6 ) including a straight-line cutout ( 6   a ) at the upper portion thereof and formed of a rubber material is inserted into the first discharge tube ( 5 ). Also, an outlet tube ( 7 ) having a tube-type shape is inserted into the intermediate outlet tube ( 6 ). The outlet tube ( 7 ) includes a flange ( 7   b ) on a lower portion thereof so as to be stopped by a circular stopper ( 2   a ) formed in the discharge port ( 2 ) of the tube container ( 1 ), and has a discharge hole ( 7   c ) formed at a center thereof and communicating with the tube container ( 1 ). 
         [0006]    In Korean Utility Model, when the tube container ( 1 ) is pressurized by a certain force, contents inside the container move through the discharge hole ( 7   c ) of the outlet tube ( 7 ), and collect in a space ( 9 ). At the same time, the cutout ( 6   a ) of the intermediate outlet tube ( 6 ) surrounding the outlet tube ( 7 ) spreads out, and thus a straight-line gap is generated. In this case, liquid contents collected in the space ( 9 ) are converted into a form of droplet while being discharged through the straight-line gap, and are discharged through the discharge hole ( 5   a ) of the first discharge tube ( 5 ). However, since the structure of Korean Utility Model for discharging contents in a form of droplet is complicated, the manufacturing time and cost increase, thereby causing a cost burden of a user.

     DETAILED DESCRIPTION 
       [0020]    Hereinafter, exemplary embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. The same reference numerals provided in the drawings indicate the same members. 
         [0021]      FIG. 1  is an exploded cross-sectional view illustrating a configuration of a tube-type cosmetic container for discharging liquid contents in a form of droplet according to a first embodiment of the present disclosure.  FIG. 2  is an assembled cross-sectional view illustrating a configuration of a tube-type cosmetic container for discharging liquid contents in a form of droplet according to a first embodiment of the present disclosure.  FIG. 3  is a view illustrating a use state of a tube-type cosmetic container for discharging liquid contents in a form of droplet according to a first embodiment of the present disclosure. 
         [0022]    Referring to  FIGS. 1 to 3 , a tube-type cosmetic container for discharging liquid contents in a form of droplet according to an exemplary embodiment of the present disclosure may include a tube body  100 , a tube neck  200 , a discharge control part  300 , a content discharging tube  400 , and an over cap  500 . 
         [0023]    The tube body  100  may store liquid contents, and may be formed of a flexible material so as to enable contents to be discharged by pressurization of a user. 
         [0024]    The tube neck  200  may be coupled to an upper portion of the tube body  100  to support the tube body  100 , and may have an outlet hole  210  formed at a central portion thereof such that contents stored in the tube body  100  can be discharged therethrough. 
         [0025]    The tube neck  200  may have a first screw thread  220  which is formed on an upper outer circumferential surface of the tube neck  200  and through which the over cap  500  is screw-coupled to the tube neck  200 . 
         [0026]    The discharge control part  300  may be coupled to the inner side of the tube neck  200 , and may control the amount of discharge when contents discharged through the outlet hole  210  move upward. In some implementations, the discharge control part  300  may include a discharge control tube  310  that is disposed at a central portion thereof and becomes gradually wider from the lower portion to the upper portion thereof. 
         [0027]    The discharge control tube  310  may downwardly extend from the central portion of the upper end of the discharge control part  300  to control the amount of discharge of contents, and may become gradually wider from the lower portion to the upper portion thereof, enabling contents to drip down in a form of droplet. 
         [0028]    As show in  FIG. 3  which illustrates a process of dripping down contents, when a user turns the tube body  100  upside down and then pressurizes the tube body  100 , a very small amount of contents among contents discharged through the outlet hole  210  may pass through a narrow lower portion of the discharge control tube  310  to be filled in the content discharging tube  400 . When the filling of content in the content discharging tube  400  is completed and a certain amount of contents continuously passes the narrow lower portion of the discharge control tube  310 , contents gather in a discharge hole  410  of the content discharging tube  400 , and then may be discharged in a form of droplet. 
         [0029]    On the other hand, a seating stopper  320  may be formed to surround the outer circumferential surface of the discharge control part  300  such that a seating protrusion  420  formed at a lower portion of the content discharging tube  400  described later is seated on the seating stopper  320 . 
         [0030]    The content discharging tube  400  may be coupled to the upper portion of the tube neck  200  to discharge contents to the outside, and may have the discharge hole  410  formed on the upper end thereof so as to allow contents to be discharged therethrough. 
         [0031]    In some implementations, the content discharging tube  400  may pressurize the discharge control part  300  to allow the discharge control part  300  to be fixed in the tube neck  200 . To this end, the seating protrusion  420  may be formed on the lower portion of the content discharging tube  400  to be seated on the seating stopper  320 . 
         [0032]    The over cap  500  may be detachably coupled to the tube neck  200  while covering the outer side of the tube neck  200 , and may have a second screw thread  510  formed on the inner circumferential surface thereof so as to be screw-coupled to the first screw thread  220  of the tube neck  200 . 
         [0033]    Also, a closing rod  520  may be provided on the undersurface of the upper end of the over cap  500  to close the discharge hole  410  of the content discharging tube  400  and thus prevent leakage of contents. 
         [0034]    Hereinafter, a tube-type cosmetic container for discharging liquid contents in a form of droplet according to a second embodiment of the present disclosure will be described in detail with reference to  FIG. 4 . 
         [0035]    Referring to  FIG. 4 , a tube-type cosmetic container for discharging liquid contents in a form of droplet according to a second embodiment of the present disclosure may not include the discharge control part  300  for controlling the amount of discharge of contents unlike the first embodiment, and may include a discharge control tube  210 ′ at a central portion of a tube neck  200 ′. The discharge control tube  210 ′ may be integrally formed so as to become wider from a lower portion to an upper portion of the tube neck  200 ′. Thus, since the discharge control part  300  need not be coupled to the inner side of the tube neck  200 , the number of parts and the assembly time can be reduced, thereby improving the productivity. 
         [0036]    On the other hand, since a tube body  100 ′, a content discharging tube  300 ′, and an over cap  400 ′ are the same as those described in the first embodiment, a detailed description thereof will be omitted herein. 
         [0037]    Hereinafter, a tube-type cosmetic container for discharging liquid contents in a form of droplet according to a third embodiment of the present disclosure will be described in detail with reference to  FIG. 5 . 
         [0038]    Referring to  FIG. 5 , a tube-type cosmetic container for discharging liquid contents in a form of droplet according to a third embodiment of the present disclosure may not include the tube neck  200  supporting the tube body  100  and having the outlet hole  210  unlike the first embodiment, and may include a content discharging tube  200 ″ integrally formed on an upper portion of a tube body  100 ″ storing contents and discharging contents out of the tube body  100 ″. The content discharging tube  200 ″ may be directly formed integrally with the tube body  100 ″. Accordingly, unlike the first embodiment, since processes of forming the tube neck  200  on the tube body  100  and coupling the content discharging tube  400  to the tube neck  200  are not need, the number of parts and the assembly time can be reduced, thereby improving the productivity. 
         [0039]    On the other hand, a discharge control tube  210 ″ may be provided at an inner side of the upper portion of the content discharging tube  200 ″. The discharge control tube  210 ″ may downwardly extend while surrounding the inner circumferential surface of the content discharging tube  200 ″ to control the amount of discharge of contents. The discharge control tube  210 ″ may be formed directly on an inner side of the content discharging tube  200 ″ so as to become wider from a lower portion to an upper portion of discharge control tube  210 ″. Accordingly, unlike the first embodiment, since the discharge control part  300  need not be coupled to the inner side of the tube neck  200 , the number of parts and the assembly time can be reduced, thereby improving the productivity. 
         [0040]    Also, a discharge hole  220 ″ may be formed on the upper end of the content discharging tube  200 ″ to discharge contents moving upward through the discharge control tube  210 ″ out of the content discharging tube  200 ″. In addition, an over cap  300 ″ provided with a closing rod  320 ″ may be coupled to the outer side of the content discharging tube  200 ″ to close the discharge hole  220 ″. 
         [0041]    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 disclosure and are not intended to limit the meanings of the terms or to restrict the scope of the present disclosure 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.
