Bottle cap assembly

Abstract

A bottle cap assembly includes a stopper and an over-cap removably coupled to a bottle. The stopper includes a cork fitted to a stopper cap with a snap-in retention ring so as to avoid the need to use any glue. The over-cap includes downwardly extending prongs, each having medial tab that releasably locks the over-cap to the stopper cap and bottle. The prongs releasably catch a ledge defined by the stopper. An inner sleeve of the over-cap conforms to an outer surface of a top portion of the bottle.

1 . A bottle assembly, comprising:
 a stopper including a stopper cap, a cork and a retention ring coupling the cork to the stopper cap; and   an over-cap removably coupled to the stopper, the over-cap comprising a prong that releasably engages the stopper.   
   
   
       2 . The assembly of  claim 1 , wherein:
 the stopper cap defines a recess;   the cork includes a cylindrical body with a first diameter and an annular top portion with a second diameter greater than the first diameter, the annular top portion being disposed in the recess; and   the retention ring is disposed beneath the annular top portion.   
   
   
       3 . The assembly of  claim 1 , wherein:
 the stopper includes a bottom annular ledge; and   the prong releasably catches the bottom annular ledge.   
   
   
       4 . The assembly of  claim 3 , wherein the prong comprises a bottom tab that extends medially to releasably catch the bottom annular ledge. 
   
   
       5 . The assembly of  claim 3 , wherein:
 the over-cap comprises a planar top portion having a top surface and a bottom surface; and   the prong extends downwardly from the bottom surface of the planar top portion of the over-cap.   
   
   
       6 . The assembly of  claim 1 , further comprising a bottle including a top opening and a top outer surface. 
   
   
       7 . The assembly of  claim 6 , wherein the over-cap comprises an inner sleeve that substantially conforms to the top outer surface of the bottle. 
   
   
       8 . The assembly of  claim 6 , wherein:
 the stopper is removably coupled to the bottle, the cork being removably disposed at least in part in the opening of the bottle; and   the over-cap is removably coupled to the stopper and the bottle.   
   
   
       9 . A bottle assembly, comprising:
 a bottle including a bottle opening and a top outer surface;   a stopper removably coupled to the bottle, the stopper including a stopper cap, a cork and a retention ring coupling the cork to the stopper cap;   an over-cap removably coupled to the stopper and the bottle, the over-cap comprising a prong that releasably engages the stopper.   
   
   
       10 . The assembly of  claim 9 , wherein:
 the stopper cap defines a recess;   the cork includes a cylindrical body with a first diameter and an annular top portion with a second diameter greater than the first diameter, the annular top portion being disposed in the recess; and   the retention ring is disposed beneath the annular top portion.   
   
   
       11 . The assembly of  claim 9 , wherein:
 the stopper includes a bottom annular ledge; and   the prong releasably catches the bottom annular ledge.   
   
   
       12 . The assembly of  claim 11 , wherein the prong comprises a bottom tab that extends medially to releasably catch the bottom annular ledge. 
   
   
       13 . The assembly of  claim 11 , wherein:
 the over-cap comprises a planar top portion having a top surface and a bottom surface; and   the prong extends downwardly from the bottom surface of the planar top portion of the over-cap.   
   
   
       14 . The assembly of  claim 9 , wherein the over-cap comprises an inner sleeve that substantially conforms to the top outer surface of the bottle. 
   
   
       15 . A bottle assembly, comprising:
 a stopper; and   an over-cap removably coupled to the stopper, the over-cap comprising a prong that releasably engages the stopper.   
   
   
       16 . The assembly of  claim 15 , wherein:
 the stopper includes a bottom annular ledge; and   the prong releasably catches the bottom annular ledge.   
   
   
       17 . The assembly of  claim 16 , wherein the prong comprises a bottom tab that extends medially to releasably catch the bottom annular ledge. 
   
   
       18 . The assembly of  claim 17 , wherein:
 the over-cap comprises a planar top portion having a top surface and a bottom surface; and   the prong extends downwardly from the bottom surface of the planar top portion of the over-cap.   
   
   
       19 . The assembly of  claim 15 , further comprising a bottle including a top opening and a top outer surface. 
   
   
       20 . The assembly of  claim 19 , wherein the over-cap comprises an inner sleeve that substantially conforms to the top outer surface of the bottle. 
   
   
       21 . The assembly of  claim 20 , wherein:
 the stopper is removably coupled to the bottle, the cork being removably disposed at least in part in the opening of the bottle; and   the over-cap is removably coupled to the stopper and the bottle.
