Ice bag for cooling of a beverage

Abstract

The invention relates to an ice bag to cool a beverage without mixing the beverage and the coolant. The bag comprises a chamber ( 10, 11 ) for a beverage and a chamber ( 10, 11 ) for a coolant, preferable ice. The chambers are separated by a separation layer ( 12 ) of foil or plastic, and the beverage is cooled, when said separation layer is in contact with the beverage on one side and with the coolant on the other side.

 i. a plurality of ice cube compartments, and 
 ii. an inner inlet for filling a coolant, preferably water to be frozen, into the inner chamber, where the coolant is distributed between the plurality of ice cube compartments, 
   the outer chamber comprises:
 i. an outer inlet for filling a beverage into the outer chamber, 
   wherein the beverage is cooled, when said separation layer, which separates the inner chamber and the outer chamber, is in contact with the beverage and with the coolant,   the ice bag is made of a soft plastic material, and   the inner chamber and the outer chamber are either fixed to the same closure element or each comprises a closure element, the closure element(s) is/are resealable mechanisms.

         3 . The ice bag according to  claim 2 , wherein the inner foil sheets comprises an outer periphery, and two inner foil sheets are joined together by a peripheral joint extending along the major part of the outer periphery of said inner foil sheets, with the exception of a peripheral areal constituting the inner inlet. 
     
     
         4 . The ice bag according to  claim 2 , wherein the outer foil sheets comprises an outer periphery, and the two outer foil sheets are joined together by a peripheral joint extending along the major part of the outer periphery of said outer foil sheets, forming the outer chamber, with the exception of a peripheral areal constituting the outer inlet and the inner inlet. 
     
     
         5 . The ice bag according to  claim 2 , wherein the inner foil sheets and the outer foil sheets comprises an outer periphery, and the two inner foil sheets and the two outer foil sheets are all joined together by a peripheral joint extending along the major part of said outer periphery of said foil sheets with the exception of a peripheral areal constituting the inner inlet and the outer inlet. 
     
     
         6 . The ice bag according to  claim 1 , wherein the inner chamber and the outer chamber both are connected and fixed to the same closure element, the closure element is adapted to open and close the inner inlet, and the closure element is adapted to open and close the outer inlet. 
     
     
         7 . The ice bag according to  claim 6 , wherein the closure element for closing and opening the inner and the outer inlets is a resealable mechanism, preferably a slider zipper, a plastic seal, a zip-lock, an adhesive strip or a Velcro strip. 
     
     
         8 . The ice bag according to  claim 1  wherein the inner chamber is divided by separate joints into a plurality of ice cube compartments. 
     
     
         9 . The ice bag according to  claim 1 , wherein the inner chamber comprises through-going passages allowing the beverage in the outer chamber to pass through the passages in the inner chamber from one position in the outer chamber to another position in the outer chamber. 
     
     
         10 . The ice bag according to  claim 1 , wherein the ice bag is made of a plastic material, which preferable is polyethylene. 
     
     
         11 . The ice bag according to  claim 1 , wherein the inner chamber is made of a thinner layer of plastic material than the outer chamber. 
     
     
         12 . The ice bag according to  claim 1 , wherein the inner chamber is made of one plastic material and the outer chamber is made of another plastic material. 
     
     
         13 . The ice bag according to  claim 1 , wherein the ice bag comprises a handle. 
     
     
         14 . An ice bag for cooling of a beverage, the ice bag comprises an inner chamber and an outer chamber, so that the outer chamber substantially surrounds the inner chamber;
 the inner chamber and the outer chamber are separated by a separation layer of foil or plastic;   the outer chamber comprises
 i. a plurality of ice cube compartments, and 
 ii. an outer inlet for filling a coolant, preferably water to be frozen, into the outer chamber, where the coolant is distributed between the plurality of ice cube compartments, 
   the inner chamber comprises:
 i. an inner inlet for filling a beverage into the inner chamber, 
   wherein cooling of the beverage is provided when said separation layer, which separates the inner chamber and the outer chamber, is in contact with the beverage and with the coolant,   the ice bag is made of a soft plastic material, and   the inner chamber and the outer chamber are either fixed to the same closure element or each comprises a closure element, the closure element(s) is/are resealable mechanisms.
