Stopper and container having the same

Abstract

The present invention relates to a stopper including: an outer cap having an upper surface with a discharge hole and a side extending downward from the outer edge of the upper surface; and an inner cap having a cylindrical body and a protrusion and combined with the outer cap, in which the protrusion has an inclined surface extending upward from the lower edge of the body toward the center and a plurality of inlet/outlet holes formed around the inclined surface, and a container having the stopper. According to the present invention, it is possible to provide a stopper that makes it possible to discharge a desired amount of liquid substance by removing slosh generated when the liquid substance is discharged out of a container, and a container having the stopper.

1 . A stopper comprising:
 an outer cap having an upper surface with a discharge hole and a side extending downward from the outer edge of the upper surface; and   an inner cap having a cylindrical body and a protrusion and combined with the outer cap,   wherein the protrusion has an inclined surface extending upward from the lower edge of the body toward the center and a plurality of inlet/outlet holes formed around the inclined surface.   
     
     
         2 . The stopper according to  claim 1 , wherein the outer cap further has a first locking step protruding from the inner surface of the side, and
 the inner cap further has a coupling portion extending outward from the body and locked to the first locking step.   
     
     
         3 . The stopper according to  claim 2 , wherein the coupling portion is formed such that a bottom further protrudes outward than a top, and the top and the bottom are connected by a curved surface. 
     
     
         4 . The stopper according to  claim 1 , wherein the outer cap further has an outer cap skirt that extends downward from the bottom of the upper surface. 
     
     
         5 . The stopper according to  claim 4 , wherein the inner cap further has an anti-leak step that is formed on the top of the body, with the inner surface in close contact with the outer cap skirt. 
     
     
         6 . The stopper according to  claim 2 , wherein the inner cap further has an inner cap skirt that extends downward from the bottom of the coupling portion. 
     
     
         7 . The stopper according to  claim 2 , wherein the outer cap further has a second locking step that protrudes from the inner surface of the side, under the first locking step. 
     
     
         8 . The stopper according to  claim 1 , wherein the outer cap further has:
 a cutting cap that has a sealing member connected with the upper surface and closing the discharge hole and a removal tab formed on the top of the sealing member; and   a cutting groove that is formed at the joint of the sealing member and the upper surface.   
     
     
         9 . The stopper according to  claim 1 , further comprising:
 a cap coupled to the upper portion of the outer cap; and   a hinged portion connecting the cap with the outer cap and being pivotable.   
     
     
         10 . A container including a container body with an opening and a stopper coupled to the opening, wherein the stopper includes:
 an outer cap having an upper surface with a discharge hole, a side extending downward from the outer edge of the upper surface, a first locking step protruding from the inner surface of the side, and a second locking step protruding from the inner surface of the side, under the first locking step; and   an inner cap having a cylindrical body, a protrusion having an inclined surface extending upward from the lower edge of the body toward the center and a plurality of inlet/outlet holes formed around the inclined surface, and a coupling portion extending outward from the body and locked to the first locking step, and   the container body includes a protrusion protruding from the outer surface of the opening and locked to the second locking step.   
     
     
         11 . The container according to  claim 10 , wherein the inner cap further has an inner cap skirt that extends downward from the bottom of the coupling portion, in close contact with the inner surface of the opening. 
     
     
         12 . The container according to  claim 10 , wherein the coupling portion is formed such that a bottom further protrudes outward than a top, and the top and the bottom are connected by a curved surface. 
     
     
         13 . The container according to  claim 10 , wherein the outer cap further has an outer cap skirt that extends downward from the bottom of the upper surface. 
     
     
         14 . The container according to  claim 13 , wherein the inner cap further has an anti-leak step that is formed on the top of the body, with the inner surface in close contact with the outer cap skirt. 
     
     
         15 . The container according to  claim 10 , wherein the outer cap further has:
 a cutting cap that has a sealing member connected with the upper surface and closing the discharge hole and a removal tab formed on the top of the sealing member; and   a cutting groove that is formed at the joint of the sealing member and the upper surface.   
     
     
         16 . The container according to  claim 10 , further comprising:
 a cap coupled to the upper portion of the outer cap; and   a hinged portion connecting the cap with the outer cap and being pivotable.
