Bottle cover assembly

Abstract

The invention relates to a stopper assembly, and more particularly, to an improved stopper to prevent a sloshing of an its liquefied content when a bottle is tilted to allow a predetermined amount of the content to be poured and to allow the content to be easily discharged. A stopper assembly includes a inner cap 20 coupled to an inlet of a bottle 10, an outer cap 30 coupled openly and closely to an outer side of the inner cap 20 to seal the inlet of the bottle 10, wherein the inner cap 20 includes a cylindrical shaped body 21 coupled to the inlet of the bottle 10; a protrusion 22 forming slope 22 a extending toward a center of an upper side of the body 21 from an edge of an lower end of the body 21 and forming an plurality of exit holes 22 b around the slope 22 a.

1 . A stopper assembly comprising:
 a inner cap  20  coupled to an inlet of a bottle  10 ;   an outer cap  30  coupled openly and closely to an outer side of the inner cap  20  to seal the inlet of the bottle  10 ;   
       wherein the inner cap  20  includes a cylindrical shaped body  21  coupled to the inlet of the bottle  10 ; and
 a protrusion  22  forming slope  22   a  extending toward a center of an upper side of the body  21  from an edge of an lower end of the body  21  and forming an plurality of exit holes  22   b  around the slope  22   a.    
 
     
     
         2 . The stopper assembly of  claim 1 , wherein the exit hole  22   b  is lengthily formed from a lower end section of the slope  22   a  to a upper end section thereof and protrusion  22   c  is formed in an edge of an lower end section of the exit hole  22   b.    
     
     
         3 . The stopper assembly according to  claim 1 , wherein the inner cap  20  is made of synthetic resin capable of elastic deformation, an edge upper end section of the body  21  is formed with an outwardly bent electric piece  21   b  and the inner surface of the outer cap  30  is formed with an annular sealing rib  31  coupled to an inner peripheral surface of a upper end of the body  21  and a circle-shaped sealing jaw  32  supporting the electric piece  22   a.    
     
     
         4 . The stopper assembly of  claim 3 , wherein the inner peripheral surface of the exiting port of the bottle  10  is formed with a concave groove  11  and the outer peripheral surface of the lower section of the body  21  is formed with a convex section  21   c  elastically coupled and disconnected to the concave groove  11 . 
     
     
         5 . The stopper assembly of  claim 4 , wherein the outer peripheral surface of the body  21  is formed with a suspending rib  21  a which is supported by a upper end section of the exiting port of the bottle  10 .
