Container cap with content reservoir system

Abstract

A cap for a container includes a base portion that connects to the container, the base portion including a mouthpiece in fluid communication with an internal cavity of the container, a content reservoir system disposed on the base portion and in selective fluid communication with the internal cavity of the container, the content reservoir system including a valve such that the content reservoir system is in fluid communication with the internal cavity when the valve is in an open state and such that the content reservoir system is not in fluid communication with the internal cavity when the valve is in a closed state, and an actuating portion that actuates the valve between the closed state and the open state to selectively open the internal cavity of the container.

What is claimed is: 
     
         1 . A cap for a container, comprising:
 a base portion configured to connect to the container, the base portion including a mouthpiece configured to be in fluid communication with an internal cavity of the container;   a content reservoir system disposed on the base portion and configured to be in selective fluid communication with the internal cavity of the container, the content reservoir system including a valve such that the content reservoir system is in fluid communication with the internal cavity when the valve is in an open state and such that the content reservoir system is not in fluid communication with the internal cavity when the valve is in a closed state; and   an actuating portion configured to actuate the valve between the closed state and the open state to selectively open the internal cavity of the container.   
     
     
         2 . The cap of  claim 1 , wherein the valve includes a pressure valve configured to open when a differential pressure between the internal cavity of the container and the content reservoir system is above a threshold value. 
     
     
         3 . The cap of  claim 2 , wherein the actuating portion includes a plunger configured to pressurize the content reservoir system. 
     
     
         4 . The cap of  claim 3 , wherein the plunger is removably secured to the content reservoir system or the base portion such that the plunger may be removed to allow access to the content reservoir system. 
     
     
         5 . The cap of  claim 3 , wherein the plunger includes a flexible button configured to deform and pressurize the content reservoir system. 
     
     
         6 . The cap of  claim 1 , wherein the content reservoir system is formed into the base portion. 
     
     
         7 . The cap of  claim 1 , wherein the mouthpiece is movably connected to the base portion such that the mouthpiece moves between a sealed position and an unsealed position. 
     
     
         8 . The cap of  claim 7 , wherein the mouthpiece extends away from the content reservoir system in the unsealed position. 
     
     
         9 . The cap of  claim 1 , wherein the content reservoir system is removable from the base portion. 
     
     
         10 . The cap of  claim 1 , wherein the valve includes an elastic material. 
     
     
         11 . The cap of  claim 1 , wherein the valve is configured to operate with at least one of a fluid and a powder. 
     
     
         12 . A content reservoir system for a container cap, comprising:
 a housing that defines the content reservoir system; and   a valve such that the content reservoir system is in fluid communication with an internal cavity of a container when the valve is in an open state and such that the content reservoir system is not in fluid communication with the internal cavity of the container when the valve is in a closed state.   
     
     
         13 . The content reservoir system of  claim 12 , further including an actuating portion configured to actuate the valve between the closed state and the open state to selectively open the internal cavity of the container to the content reservoir system. 
     
     
         14 . The content reservoir system of  claim 13 , wherein the valve includes a pressure valve configured to open when a differential pressure between the internal cavity of the container and the content reservoir system is above a threshold value. 
     
     
         15 . The content reservoir system of  claim 14 , wherein the actuating portion includes a plunger configured to pressurize the content reservoir system. 
     
     
         16 . The content reservoir system of  claim 15 , wherein the plunger is removably secured to the content reservoir system or the base portion such that the plunger may be removed to allow access to the content reservoir system. 
     
     
         17 . The content reservoir system of  claim 16 , wherein the plunger includes a flexible button configured to deform and pressurize the content reservoir system. 
     
     
         18 . The content reservoir system of  claim 12 , wherein the valve includes an elastic material. 
     
     
         19 . The content reservoir system of  claim 12 , wherein the valve is configured to operate with at least one of a fluid and a powder. 
     
     
         20 . A container including:
 a container housing defining an inner cavity configured to hold a fluid; and   a cap including:
 a base portion configured to connect to the container, the base portion including a mouthpiece configured to be in fluid communication with an internal cavity of the container; 
 a content reservoir system disposed on the base portion and configured to be in selective fluid communication with the internal cavity of the container, the content reservoir system including a valve such that the content reservoir system is in fluid communication with the internal cavity when the valve is in an open state and such that the content reservoir system is not in fluid communication with the internal cavity when the valve is in a closed state; and 
 an actuating portion configured to actuate the valve between the closed state and the open state to selectively open the internal cavity of the container.
