Liquid container

Abstract

An exemplary embodiment of the present invention relates to a liquid container that prevents a liquid substance from flowing down from the outlet by minimizing surface energy generated between the liquid substance and the outlet, and prevents leakage at a joint between the body and the guide. A liquid container according to an exemplary embodiment of the present invention includes a body containing a liquid substance and discharging the liquid substance through a mouth and a guide connected to the mouth and having an outlet for discharging the liquid substance, wherein a first hydrophobic layer is formed by hydrophobic treatment on the surface of the outlet.

1 . A liquid container, comprising:
 a body containing a liquid substance and discharging the liquid substance through a mouth; and   a guide connected to the mouth and having an outlet for discharging the liquid substance,   wherein a first hydrophobic layer is formed by hydrophobic treatment on the surface of the outlet.   
     
     
         2 . The liquid container of  claim 1 , wherein the first hydrophobic layer is integrally connected to the inner surface, the end portion, and the outer surface of the outlet. 
     
     
         3 . The liquid container of  claim 1 , wherein a second hydrophobic layer is formed by hydrophobic treatment on the surface of the mouth. 
     
     
         4 . The liquid container of  claim 3 , wherein the second hydrophobic layer is integrally connected to the inner surface, the end portion, and the outer surface of the mouth. 
     
     
         5 . The liquid container of  claim 1 , wherein a third hydrophobic layer formed by hydrophobic treatment on the inner surface of the body. 
     
     
         6 . The liquid container of  claim 1 , wherein the guide comprises:
 an outlet member forming the outlet and having a flange at a portion closely contacting the mouth;   a cap integrally connected to a side of the outlet member to open and close the outlet; and   a connector thread-fastened to the mouth, with a protrusion held by the flange,   wherein a first hydrophobic layer is further formed on the inner surface of the flange contacting the mouth and a second hydrophobic layer is further formed at the end portion of the mouth.   
     
     
         7 . The liquid container of  claim 6 , wherein the connector further forms a fourth hydrophobic layer on the inner surface to be in close contact with the sides of the first hydrophobic layer of the flange and the second hydrophobic layer of the mouth. 
     
     
         8 . The liquid container according to  claim 1 , wherein the hydrophobic treatment forms a hydrophobic layer on a corresponding surface by one of thermal-spraying a hydrophobic substance on a corresponding surface and immersing a corresponding surface into molten metal with a hydrophobic substance and then taking out the corresponding surface. 
     
     
         9 . The liquid container of  claim 8 , wherein the hydrophobic layer is made of one of Teflon, paraffin, and wax. 
     
     
         10 . The liquid container of  1 , wherein the hydrophobic treatment forms a hydrophobic layer on a corresponding surface by treating a silicon-based or fluorine-based solution after forming an oxide film on the corresponding surface. 
     
     
         11 . The liquid container of  claims 1 , wherein the hydrophobic treatment forms a hydrophobic layer on a corresponding surface by one of thermal spraying, etching by sputtering, and variation of a surface molecular structure by plasma. 
     
     
         12 . A liquid container containing liquid substance and discharging the liquid substance through a mouth, wherein a hydrophobic layer is formed by hydrophobic treatment on the surface of the mouth. 
     
     
         13 . A liquid container comprising:
 a body containing a liquid substance and discharging the liquid substance through a mouth; and   an outlet member having an outlet connected to the mouth to discharge the liquid substance,   wherein a hydrophobic layer is formed by hydrophobic treatment on the surface of at least one of the mouth and the outlet.
