Cosmetic container with improved sealing ability

Abstract

The present invention relates to a cosmetic container with improved sealing ability, the cosmetic container including: a content container accommodated therein with contents and having an outer wall; a content container lid configured to open and close the content container and having a lower extension protrusion wheel; and a sealing packing formed of an elastic material, and double-injection-molded or insert-injection-molded on an outer side of the lower extension protrusion wheel of the content container lid to make close contact with an inner periphery of the outer wall of the content container when the content container lid is closed.

What is claimed is: 
     
         1 . A cosmetic container with improved sealing ability, the cosmetic container comprising:
 a content container accommodated therein with contents and having an outer wall;   a content container lid configured to open and close the content container and having a lower extension protrusion wheel; and   a sealing packing formed of an elastic material, and double-injection-molded or insert-injection-molded on an outer side of the lower extension protrusion wheel of the content container lid to make close contact with an inner periphery of the outer wall of the content container when the content container lid is closed.   
     
     
         2 . The cosmetic container of  claim 1 , wherein the content container includes a bottom surface, an inner wall extending upward from the bottom surface, and the outer wall extending upward while being spaced outward from the inner wall by a predetermined interval. 
     
     
         3 . The cosmetic container of  claim 1 , wherein the sealing packing has a ring shape which completely surrounds an outer periphery of the lower extension protrusion wheel of the content container lid. 
     
     
         4 . The cosmetic container of  claim 1 , wherein the sealing packing includes an insertion part and an exposed part which is stepped from the insertion part, and
 when the content container lid is closed, the insertion part makes close contact with the inner periphery of the outer wall of the content container while an end of the exposed part presses an upper end of the outer wall of the content container so that the content container is doubly sealed.   
     
     
         5 . The cosmetic container of  claim 1 , wherein a hinge contact part protrudes from one side of the sealing packing to make contact with a second hinge part formed on the content container lid. 
     
     
         6 . The cosmetic container of  claim 1 , wherein the content container lid and at least a portion including an outer periphery of the sealing packing have mutually different colors. 
     
     
         7 . The cosmetic container of  claim 1 , wherein first and second hinge parts are formed on the content container and the content container lid, respectively, and
 when the content container lid is opened, an opening angle of the content container lid is adjusted by a frictional force between the first and second hinge parts.
