FOOD PRODUCT PACKAGE AND METHOD OF ITS PRODUCTION Russian patent published in 2009 - IPC A47J36/28 B65D81/34 

FIELD: food industry.

SUBSTANCE: food product package comprises lower and upper sections of containers. The lower section consists of at least one pair of communicating main containers with common flat flanging. The upper section consists of at least one first-type container with flat flanging which is made as a unit with the upper wall of the second main container of the lower section. The upper wall of the second main container is deflectable when a user applies external load to its central part which is a concave one. The lower part of the second main container is inclined in the direction to the respective first main container; the maximal height of its side wall does not exceed the height of the side wall of the respective first main container. A closed chamber with liquid reactant is placed in the second main container. The first-type container of the upper section is placed in the cavity of the first main container of the lower section producing a cell between its bottom and the bottom of the first main container of the lower section with a solid reactant being put in the cell.

EFFECT: invention allows for the increase of the performance parametres of the food product package due to ensuring tightness of both the reaction chamber and the lower section containers as well as for the simplification of the package design and method of its production.
