Child-resistant sealing cap for a container

Abstract

A sealing cap for a container provides a resealable, multi-piece assembly featuring a watertight and airtight seal and child resistance against opening the sealing cap, and which is designed to be snapped on to the top of conventional aluminum cans and extendable to common food and herb matter containers.

What is claimed is: 
     
         1 . A cap assembly for sealing a container, comprising:
 a) an outer cap comprising: a top comprising a plurality of notches disposed on an underside thereof; and a tab disposed at a lateral edge of said top and extending past a bottom edge of a side wall;   b) an inner cap comprising a top comprising a plurality of teeth disposed thereon;   c) a collar;   d) a spacer; and   e) a sealing ring.   
     
     
         2 . A method for opening a liquid container having a pull-tab securing the contents of the container in a body thereof, said container further having a cap assembly disposed over a top of said body of said container, and enclosing said pull tab, said method further comprising:
 a) pulling a tab on a lateral edge of an outer cap of said sealing cap to remove said outer cap from an inner cap of said cap assembly;   b) twisting said inner cap to remove said inner cap from a collar of said cap assembly and to expose said pull tab of said container through a central opening in said collar;   c) inserting said outer cap tab through said central opening in said collar;   d) positioning said outer cap tab underneath a portion of said container pull tab; and   e) using said outer cap tab, applying a force to said container pull tab to cause said container to open.   
     
     
         3 . A cap assembly for sealing a container, comprising:
 a) an outer cap comprising:
 i) a top comprising a plurality of notches disposed on an underside thereof; 
 ii) a side wall extending from said top; and 
 iii) a tab disposed at a lateral edge of said top and extending past a bottom edge of said side wall; 
   b) an inner cap comprising:
 i) a top comprising a plurality of teeth disposed thereon; 
 ii) an outer wall extending from said top; 
 iii) an inner wall extending from an underside of said top; and 
 iv) a cavity disposed between said outer wall and said inner wall; 
   c) a collar comprising:
 i) an outer wall; 
 ii) a lip extending from a top side of said outer wall; 
 iii) an inner wall; 
 iv) a central opening having a perimeter defined by said inner wall; and 
 v) a cavity disposed between said outer wall and said inner wall; 
   d) a spacer comprising a central opening; and   e) a sealing ring;   wherein said teeth of said inner cap are adapted to mate with said notches of said outer cap,   wherein said inner wall of said inner cap is adapted to mate with said inner wall of said collar,   wherein said cavity of said inner cap is adapted to receive said spacer therein, and   wherein said cavity of said collar is adapted to receive said sealing ring therein.
