Self-heating container

Abstract

The present invention relates to a heating container. There are types of food which should be eaten after being warmed up at home or in a restaurant. Hot sops or hot stews can be eaten after being heated on a portable gas range. However, it is impossible or very inconvenient to heat pan-fried foods, boiled beef, fried foods, rice cakes and the like on a gas range. The heating container of the present invention has a self-heating function and is very useful because the heating container allows food to be kept warm until the end of the meal when various foods are placed on the heated heating container, whereby enabling the distinct tastes of the foods not to be lost until the end of the meal.

1 . A self-heating container, comprising:
 a double container inner space part  12  formed of a double container upper layer  10  and a double container lower layer  11 , with a solution such as sodium acetate , sodium thiosulfate, etc. or an aqueous solution being filled in the double container inner space part  12 , and   an impact module  35  with an impact elastic member means  21 .   
     
     
         2 . A self-heating container according to  claim 1 , wherein the materials of said double container upper layer 10 and said double container lower layer 11 are stainless steel. 
     
     
         3 . A self-heating container according to  claim 1 , wherein the materials of said double container upper layer  10  and said double container lower layer  11  are synthetic resin. 
     
     
         4 . A self-heating container, comprising:
 a double container inner space part  12  of which either a double container upper layer  10  or a double container lower layer  11  is made from an inoxidable metallic material, with the other layer being made from a synthetic resin material, with a solution such as sodium acetate , sodium thiosulfate, etc. or an aqueous solution being filled in the double container inner space part  12 , and   an impact module  35  with an impact elastic member means  21 .   
     
     
         5 . A self-heating container, comprising:
 a double container inner space part  12  formed of a double container upper layer  10  and a double container lower layer  11 , with a solution such as sodium acetate , sodium thiosulfate, etc. or an aqueous solution being filled in the double container inner space part  12 , wherein a reaction of a solution such as sodium acetate , sodium thiosulfate, etc. or an aqueous solution is trigged as a certain impact is externally inputted using an ultrasonic oscillation means.   
     
     
         6 . A self-heating container, comprising:
 an impact module  30  configured in such a way that a circular circumferential portion is protruded to form a small container shape and having an impact module inner space  17  and an assembly groove  16  formed by forming a protrusion at its lower and upper side, respectively, in order for the assembly groove  16  to be formed at an upper side of an outer circumferential portion, with the assembly groove  16  being formed in order for the impact elastic member means  21  to help form itself in a polygonal shape, with a recovery spring  20  being provided at a lower side of the impact elastic member means  21 , thus helping recover the impact elastic member means  21 , with a protrusion part  22  being formed in the vicinity of the double container upper layer  10  at the upper side of the impact elastic member means  21 , and in the above construction as the center portion where the protrusion part  22  of the double container upper layer  10  is pressed, the protrusion part  22  strongly presses the impact elastic member means  21 , and said impact elastic member mean  21  with its outer circumferential side being caught by means of the escape prevention shoulder  14  is configured with its upper side being concave, and its lower side being convex, so the impact elastic member means  21  stores elastic force, and when a user releases his hand from a pressing state of the double container upper layer  10 , the protrusion part  22  no longer presses the impact elastic member means  21 , and the impact elastic member means  21  can recover for itself, but the recovery can be easily performed by means of an elastic force of the compressed impact elastic member means  21 , and here since the impact elastic member means  21  is caught by means of the escape prevention shoulder  15 , it does not disengage from the assembly groove  16 , and a solution such as sodium acetate, sodium thiosulfate, etc. and an aqueous solution in the double container inner space part reacts, thus generating heat.
