Self-heating package for pre-cooked foods

Abstract

A self-heating package for pre-cooked foods of the type comprising a container ( 1 ) attached to a receptacle ( 2 ), both of these ( 1, 2 ) being housed within an outer container ( 3 ) that is resistant to high temperatures. The receptacle ( 2 ) has on its lower side a slitting ( 21 ) around an inner striker ( 22 ). Said striker ( 22 ) has several pins ( 23 ) upon which a water bag ( 5 ) is arranged, the remaining volume of the receptacle ( 2 ) being filled with an exothermal reactive product ( 6 ) that is in contact with the water. This product is solid state or powdered calcium oxide, such that when the user presses against the bottom of the receptacle ( 2 ) the striker ( 22 ) is shifted against the bag ( 5 ) until breaking said bag ( 5 ), the water then coming into contact with the reactive product ( 6 ), and thus causing the container ( 1 ) and the food content to be heated.

1 . A self-heating package for pre-cooked foods of the type comprising a container ( 1 ) for the pre-cooked food attached to a receptacle ( 2 ) with means for heating the packaged food product, both of these ( 1 ,  2 ) being housed within an outer container ( 3 ) that is resistant to moderately high temperatures, characterised in that the lower side of the receptacle ( 2 ) has a multiple slitting ( 21 ) around an inner striker ( 22 ), said striker ( 22 ) configuring an upper edge having several pins ( 23 ), spears or the like upon which a water bag ( 5 ) is arranged, the remaining volume of the receptacle ( 2 ) being filled with an exothermal reactive product ( 6 ) that is in contact with the water, this configuration being operatively suitable so that when the user presses against the bottom of the receptacle ( 2 ) with his or her fingers, this causes a significant shift of the striker ( 22 ) against the water bag ( 5 ), facilitated due to the extension of said slitting ( 21 ), until breaking the water bag ( 5 ), the water then coming into contact with the reactive product ( 6 ), and thus causing said exothermal reaction that causes the container ( 1 ) and the food content to be heated.  
   
   
       2 . A container according to  claim 1 , characterised in that the exothermal reactive product ( 6 ) is solid state or powdered calcium oxide.  
   
   
       3 . A container according to  claim 1 , characterised in that the container ( 1 ) is fixed at its base by means of adhesive to the receptacle ( 2 ) for the heating means, both of these ( 1 ,  2 ) being mutually joined to the outer container ( 3 ), also by means of an adhesive on its side walls.  
   
   
       4 . A container according to  claim 1 , characterised in that the outer container ( 3 ) is made of treated cardboard.  
   
   
       5 . A container according to  claim 1 , characterised in that it comprises an outer insulating package ( 4 ) in which the assembly formed by the food product container ( 1 ), the heating means receptacle ( 2 ) and the outer integrating container ( 3 ) are housed, this package ( 4 ) having a weakened contour ( 41 ) for opening an upper cover ( 42 ) for accessing the container ( 1 ) and a lower window ( 44 ) defined by a second weakened contour ( 43 ) that configures an access for pressing down the striker ( 22 ).
