Self-heating beverage container

Abstract

The present invention discloses a self-heating beverage container to heat beverages conveniently. The self-heating beverage container offers a user-friendly, efficient, and economically viable solution for producing single-serve hot beverages on the go. The self-heating beverage container include a paperboard carton or corrugated paperboard sleeving, an insulated container bag housing a bag made from mylar or polypropylene and lined with a reflective foil layer, a packet containing exothermic minerals, and a liquid chamber with a puncture device. The self-heating beverage container upon activation of the puncture device releases water into the insulated container bag, initiating an exothermic reaction that rapidly warms the beverage. The integration of these components ensures optimal heating efficiency and user experience, addressing the shortcomings of prior art and enabling seamless widespread adoption of self-heating beverage containers.

1 . A self-heating beverage container, comprising:
 a paperboard carton defining an interior space;   an insulated container bag located within the interior space of the paperboard carton or corrugated paperboard sleeving;   a bag within the insulated container bag, wherein the bag comprises an open end and a close end, wherein the bag is configured to contain a beverage;   a mineral pocket within the insulated container bag attached to the bag, wherein—the mineral pocket is configured to contain, and does contain, minerals;   said minerals having a chemical structure that cause the generation of heat when combined with a liquid;   a liquid chamber within the insulated container bag attached to the bag either by the bag's fitment or glue, wherein the chamber contains the liquid and is positioned proximate to an upper portion of the interior space of the paperboard carton; and   a puncture device mounted on an exterior surface of the paperboard carton or corrugated paperboard sleeving, adjacent to the chamber, wherein the puncture device is operable to rupture the chamber upon activation,   wherein the mineral pocket is configured to receive the liquid released from the ruptured liquid chamber, and   wherein an exothermic reaction between the released liquid and the minerals generates heat to warm the beverage contained within the bag.   
     
     
         2 . The system of  claim 1 , wherein the paperboard carton is a corrugated paperboard sleeving. 
     
     
         3 . The system of  claim 1 , further including a fitment configured to cover the open end of the bag. 
     
     
         4 . The system of  claim 3 , wherein the fitment forms the neck of the self-heating beverage container. 
     
     
         5 . The system of  claim 4 , further including a lid and the fitment is configured to receive said lid. 
     
     
         6 . The system of  claim 1 , wherein the mineral pocket is attached to the mylar bag. 
     
     
         7 . The system of  claim 6 , further including glue attaching the said liquid chamber to the mylar bag. 
     
     
         8 . The system of  claim 7 , wherein the glue attaching the said liquid chamber to the mylar bag is a filament of the bag. 
     
     
         9 . The system of  claim 1 , wherein the paperboard carton is lined with a foil layer, wherein the foil layer is formed of a material selected from a group, wherein the group comprises tin, aluminium, and copper. 
     
     
         10 . The system of  claim 1 , wherein the minerals contained in the mineral pocket comprise magnesium and iron. 
     
     
         11 . The system of  claim 1 , wherein the bag is constructed of mylar. 
     
     
         12 . The system of  claim 1 , wherein the bag is constructed of polypropylene. 
     
     
         13 . The system of  claim 1 , wherein the liquid contained in the liquid chamber is water. 
     
     
         14 . The system of  claim 1 , wherein the puncture device is a device selected from a first group, wherein the first group comprising a mechanical puncture device and an electrical puncture device. 
     
     
         15 . The system of  claim 1 , wherein the puncture device is activated by an activation movement selected from a second group, wherein the second group comprises a pulling movement, a pushing movement, a twisting movement and a turning movement. 
     
     
         16 . The system of  claim 1 , wherein the puncture device comprises a plastic casing, a push button, a flat area, a hollow tube and a sharp element, wherein the hollow tube receives the sharp element. 
     
     
         17 . A method for manufacturing a self-heating beverage container, comprising:
 puncturing a hole in a carton;   placing a puncture device in the punctured hole;   cutting an insulated container bag to size;   inserting a bag inside the insulated container bag;   positioning a mineral pocket within the insulated container bag around the bag;   attaching a liquid chamber to the top of the insulated container bag;   feeding the insulated container bag through said carton with the mouth of the bag fitting within an opening in said carton as a fitment to form the neck;   gluing the bottom of said carton shut;   filling the bag with a beverage and vacuum sealing the bag, and   pressing and sealing the lid on top of the paperboard carton or corrugated paperboard sleeving.   
     
     
         18 . The method of  claim 17 , wherein the puncture device is affixed to said carton using an adhesive. 
     
     
         19 . The method of  claim 17 , wherein the mineral pocket is positioned concentrically around the bag within the insulated container bag. 
     
     
         20 . The method of  claim 17 , further including the step of filling said bag with a beverage prior to insertion of same into the insulated container bag.
