FIELD: food industry.
SUBSTANCE: method for preparing a sterilised package for a ready-to-eat dish, comprising steps of, taking a main container, which defines a main volume, intended for placing the main food product and having a first opening in the upper part surrounded by a first flat edge. Further, at least one additional container is taken, having a second opening in the upper part surrounded by a second flat edge, an additional container is introduced into the main container, such that the first edge and the second edge are flush mounted. Additional food product is introduced into the additional volume, main food product is introduced into the main volume. By means of a first sealing head facing the first edge, a perimeter seal is placed between the cover film to cover the first and second openings and the first edge. By means of a second sealing head, facing the second edge and physically different from the first sealing head, an internal seal is formed between the cover film and the second edge. First sealing head forms the first sealing profile, and the second sealing head forms the second sealing profile, both profiles are closed profiles. First sealing profile repeats the shape of the first edge without including a second edge. Internal seal is less durable than said perimeter seal.
EFFECT: invention provides simultaneous sterilisation of two containers sealed with a single protective film.
