Attachment for a beverage container

Abstract

An attachment for a beverage container may comprise a cap configured to attach to an opening in the beverage container. The cap comprises an opening. The attachment also comprises a tube passing through the cap. The opening in the cap is located proximate to a first end of the tube and a second end of the tube is configured to be located within the beverage container when the cap is attached to the beverage container, such that a beverage contained in the beverage container can flow through the tube and out of the opening in the cap. The attachment also comprises a container attached to the tube and configured to hold a liquid. The container comprises an opening to allow the liquid to flow from the container into the tube and out of the opening in the cap. The attachment also comprises a restrictor between the opening of the container and the tube to control and/or restrict the flow of the liquid from the container into the tube. The restrictor and the tube are configured such that the liquid begins to exit the opening in the cap before the beverage begins to exit the opening in the cap.

1 . An attachment for a beverage container comprising:
 a cap configured to attach to an opening in the beverage container, the cap comprising an opening;   a tube passing through the cap, wherein the opening in the cap is located proximate to a first end of the tube and a second end of the tube is configured to be located within the beverage container when the cap is attached to the beverage container, such that a beverage contained in the beverage container can flow through the tube and out of the opening in the cap;   a container attached to the tube and configured to hold a liquid, the container comprising an opening to allow the liquid to flow from the container into the tube and out of the opening in the cap; and   a restrictor between the opening of the container and the tube to control and/or restrict the flow of the liquid from the container into the tube, the restrictor and the tube configured such that the liquid begins to exit the opening in the cap before the beverage begins to exit the opening in the cap.   
     
     
         2 . The attachment of  claim 1 , wherein at least a portion of the container is located within the cap and the tube extends through the container. 
     
     
         3 . The attachment of  claim 1 , wherein the restrictor has an open and a closed position, and wherein the restrictor in the closed position prevents the liquid from flowing from the container. 
     
     
         4 . The attachment of  claim 3 , wherein the restrictor is translated in a first direction in order to transition from the closed position to the open position. 
     
     
         5 . The attachment of  claim 3 , wherein the restrictor has a plurality of open positions, and wherein a different volume of the liquid can flow from the container in each of the plurality of open positions. 
     
     
         6 . The attachment of  claim 5 , wherein the restrictor is further translated in the first direction in order to transition between each of the plurality of open positions, and wherein the restrictor comprises a plurality of holes, and translating the restrictor in the first direction changes the number of holes the liquid is able to flow from the container through. 
     
     
         7 . The attachment of  claim 5 , wherein the restrictor is rotated in order to transition between each of the plurality of open positions, and wherein the restrictor comprises a plurality of holes, wherein each hole of the plurality of holes has a different diameter, and rotating the restrictor between each of the plurality of open positions changes the diameter of the hole the liquid is able to flow from the container through. 
     
     
         8 . The attachment of  claim 1 , wherein the container comprises a vent to allow air to enter the container. 
     
     
         9 . The attachment of  claim 1 , further comprising a second restrictor within the tube to control and/or restrict the flow of the beverage through the tube and out of the opening in the cap, wherein the second restrictor is a non-return valve. 
     
     
         10 . The attachment of  claim 1 , wherein the container is separable from the attachment and/or the beverage container. 
     
     
         11 . The attachment of  claim 1 , wherein the container is located at an end of the beverage container distal to the opening in the beverage container. 
     
     
         12 . The attachment of  claim 1 , wherein the container configured to be variable in volume. 
     
     
         13 . (canceled) 
     
     
         14 . A beverage dispensing system comprising:
 the attachment comprising a cap configured to attach to an opening in the beverage container, the cap comprising an opening, a tube passing through the cap, wherein the opening in the cap is located proximate to a first end of the tube and a second end of the tube is configured to be located within the beverage container when the cap is attached to the beverage container, such that a beverage contained in the beverage container can flow through the tube and out of the opening in the cap, a container attached to the tube and configured to hold a liquid, the container comprising an opening to allow the liquid to flow from the container into the tube and out of the opening in the cap and a restrictor between the opening of the container and the tube to control and/or restrict the flow of the liquid from the container into the tube, the restrictor and the tube configured such that the liquid begins to exit the opening in the cap before the beverage begins to exit the opening in the cap; and   a beverage container comprising an opening, wherein the attachment is attached to the opening.   
     
     
         15 . The beverage dispensing system of  claim 14 , wherein:
 the beverage container comprises an inlet opening configured to connect to a container to receive liquid therefrom.
