Accommodation bag

Abstract

This invention consists of an accommodation bag such that one outer bag accommodates multiple inner accommodation bags and at least one of the inner accommodation bags is a liquid-accommodation bag from which a liquid flows. Also, the liquids or goods that flow out from other multiple accommodation bags in the outer bag are processed and used by mixing with or coming into contact with each other. Therefore, it is also possible to use the processed liquid for drinking or eating by taking it via the bottom of the outer bag. As a heating means, either an outside means, such as a microwave oven or the like, or an independent container installed inside the liquid-accommodation bag, is used. The heat-generation means inside the liquid-accommodation bag is such that heat is generated when there are combined together at least two kinds of materials that generate heat by chemically reacting together, and such that only such generated heat can be utilized.

1 - 9 . (canceled)  
   
   
       10 . A container, comprising: 
 an outer bag;    an internal heating element;    a first inner bag accommodated in said outer bag and filled with a liquid, wherein the internal heating element is installed in said first inner bag for heating said liquid thereby raising a pressure of said liquid inside said first inner bag, said first inner bag being made liquid-impermeable except at least for a first vapor-releasing hole that is positioned in an upper part thereof and closed by a first seal configured to open when the pressure of said liquid reaches a predetermined level thereby allowing said heated liquid to escape said first inner bag as vapor; and    a second inner bag accommodated in said outer bag and containing therein a substance to be mixed with said vapor, said second inner bag being made liquid permeable at least partially for allowing said heated liquid, after escaping said first inner bag as vapor, to enter said second inner bag and to heat and be mixed with said substance;    said outer bag having a second vapor-releasing hole that is formed at the top of said outer bag and closed by a second seal configured to open when a pressure inside said outer bag reaches a predetermined value, and a liquid-releasing hole formed at the bottom of said outer bag;    wherein said second inner bag is directly bonded to the bottom of said outer bag.    
   
   
       11 . The container of  claim 10 , wherein said substance comprises at least one of solid and liquid foods.  
   
   
       12 . The container of  claim 10 , further comprising a plurality of said second inner bags disposed around and coelevational with said first inner bag.  
   
   
       13 . The container of  claim 10 , wherein said liquid is edible.  
   
   
       14 . The container of  claim 10 , wherein at least a portion of said second inner bag and the substance contained therein are positioned below the first vapor-releasing hole of said first inner bag.  
   
   
       15 . The container of  claim 10 , wherein said second seal is time adjustable.  
   
   
       16 . The container of  claim 15 , further comprising an indicator for displaying the time when said second seal is open.  
   
   
       17 . The container of  claim 10 , further comprising a pressure indicator for indicating the pressure inside said outer bag.  
   
   
       18 . The container of  claim 10 , wherein said heating element includes at least two kinds of material which chemically react with each other and at the same time generate heat for heating said liquid, said at least two kinds of material being stored separately and isolated from said liquid, said at least two kinds of material being mixed to react upon application of an external force to said container.  
   
   
       19 . The container of  claim 10 , wherein said second inner bag is positioned substantially co-elevational with the first inner bag.  
   
   
       20 . A container, comprising: 
 an outer bag;    a first inner bag accommodated in said outer bag, filled with a liquid and equipped with an internal heating element for heating said liquid in said first inner bag, said first inner bag being made liquid-impermeable except at least for a first vapor-releasing hole that is positioned in an upper part thereof and closed by a first seal configured to open when a pressure inside said first inner bag reaches a predetermined level by heating said liquid, thereby allowing said heated liquid to escape said first inner bag as vapor; and    a second closed inner bag accommodated in said outer bag, positioned substantially co-elevational with the first inner bag and containing therein a substance to be mixed with said vapor, said second inner bag being made liquid permeable at least partially for allowing said liquid, after escaping said first inner bag as vapor, to enter said second inner bag and to heat and be mixed with said substance.    
   
   
       21 . The container of  claim 20 , wherein 
 at least a portion of said second inner bag and the substance contained therein are positioned below the first vapor-releasing hole of said first inner bag; and    said internal heating element is configured to generate sufficient heat to cause said liquid to escape said first inner bag, as vapor, in an amount sufficient for submergence of said portion of said second inner bag and the substance contained therein.    
   
   
       22 . The container of  claim 20 , wherein said outer bag has a second vapor-releasing hole that is formed at the top of said outer bag and closed by a second seal configured to open when a pressure inside said outer bag reaches a predetermined value.  
   
   
       23 . The container of  claim 20 , wherein said outer bag has a liquid releasing hole formed at the bottom of said outer bag.  
   
   
       24 . The container of  claim 23 , wherein said second inner bag is directly bonded to the bottom of said outer bag.  
   
   
       25 . The container of  claim 20 , wherein said liquid and substance are edible.  
   
   
       26 . The container of  claim 20 , further comprising a plurality of said second closed inner bags disposed around said first inner bag.  
   
   
       27 . The container of  claim 21 , wherein 
 said portion of said second inner bag is directly bonded to the bottom of said outer bag; and    said internal heating element is configured to generate sufficient heat to cause said liquid to escape said first inner bag, as vapor, in an amount sufficient for submergence of said portion of said second inner bag and the substance contained therein.    
   
   
       28 . The container of  claim 24 , wherein at least a portion of said second inner bag and the substance contained therein are positioned below the first vapor-releasing hole of said first inner bag.
