Removable Bottle Cap Assembly with Internal Storage Compartment

Abstract

A removable cap assembly 100, 200, 300 includes a first portion 102, 302 defining a central axis 101 and configured to removably interface with a container opposite a mating surface 110 of the first portion; a second portion 122, 322, adjacent to the mating surface, and comprising lateral sidewalls 124 and a top surface 128; and a lower sealing member 142, 252 opposite the top surface that, with the lateral sidewalls 124 and the top surface, define a compartment 150 within the second portion. The removable cap assembly is arranged such that at least one component of the second portion is movable linearly with respect to the central axis so as to breach the internal compartment.

What is claimed is: 
     
         1 . A removable flow-through cap assembly for a container, the assembly comprising:
 a first portion configured to removably interface with a container;   a second portion which is securable to a container by the first portion and defining lateral sidewalls and a top surface defining a top aperture; and   a lower sealing member affixed to at least one of the first portion and the second portion, the lower sealing member defining with the lateral sidewalls and the top surface an internal compartment:   
       wherein the removable flow-through cap assembly is arranged such that at least one component of the first portion or of the second portion is movable between a first position and a second position so as to breach the internal compartment and allow fluid to flow through opposed ends of the assembly, wherein: 
       the second portion comprises a pliable drinking nipple defining the lateral sidewalls and the top surface with the top aperture, and the lower sealing member is affixed to the drinking nipple opposite the top surface; and 
       the at least one component is the first portion which comprises a screw ring,  15  and the removable flow-through cap assembly further comprises:
 a cutting element arranged to breach the sealing member when the screw ring is moved from a first position relative to a container to which the screw ring is interfaced and a second position in which the screw ring is tightened against the container which drives the sealing member against the cutting element. 
 
     
     
         2 . The removable cap assembly according to  claim 1 , further comprising a retaining ring removably affixed to a surface of the screw ring. 
     
     
         3 . The removable cap assembly according to  claim 1 , wherein the cutting element defines an outboard lip and an extension above the lip facing the sealing member so as to breach the sealing member when the screw cap is tightened on the container. 
     
     
         4 . The removable cap assembly according to  claim 1 , wherein the first portion further comprises multiple concentric threaded rings of different internal diameter arranged in a staggered fashion, wherein each concentric threaded ring is configured to removably interface with a different type of container. 
     
     
         5 . The removable cap assembly according to  claim 1 , wherein the removable cap assembly is disposable.
