2 . Food product package according to claim 1 , characterized in that said engagement means comprise a U-shaped upturned terminal portion ( 10 ) of the wall of the half-shell of non-edible material ( 2 ), with which the half-shell ( 8 ) of edible material is to be associated, and a terminal portion ( 14 ) of the other half-shell ( 4 ) of non-edible material.

3 . Package according to claim 1 , characterized in that said U-shaped upturned terminal portion ( 10 ) has a substantially flat flange ( 12 ) projecting outwards, and said terminal portion ( 14 ) of the wall of the other half-shell ( 4 ) has a substantially flat flange ( 16 ) projecting outwards, said flanges ( 12 , 16 ) being in an overlapping relationship in the engaged condition of said engagement means ( 6 ).

4 . Package according to claim 1 , characterized in that said half-shell or half-shells ( 8 ) of edible material, in the assembled configuration of the packaging, has an annular mouth edge ( 26 ) bearing against said flange ( 12 ) of said upturned wall portion ( 10 ) of the half-shell of non-edible material ( 2 ) with which it is associated.

5 . Package according to claim 1 , characterized in that said half-shell or said plurality of half-shells ( 8 ) of edible material has a total wall thickness such that said symmetrical body is formed.

6 . Package according to claim 1 , characterized in that said container comprises a first half-shell ( 2 ) of non-edible material, having a concave wall ( 48 ) surrounded by a substantially flat flange ( 56 ) from which an end wall portion extends in the form of a collar ( 58 ), and a second half-shell ( 4 ) of non-edible material, having a concave wall ( 50 ) in whose end portion ( 60 ) said wall portion in the form of a collar ( 58 ) of the other half-shell ( 2 ) is adapted to engage, said engagement means ( 6 ) comprising said wall portion in the form of a collar ( 58 ) and said end portion ( 60 ), wherein the half-shell of edible material ( 8 ) is in a position in which it bears against said flange ( 56 ).

7 . Package according to claim 6 , characterized in that said engagement means ( 6 ) further comprise complementary formations ( 62 , 64 ), formed in said wall portion in the form of a collar ( 58 ) and in said end portion ( 60 ), said formations being capable of engagement by form fit or snap action.

8 . Package according to claim 6 , characterized in that said half-shell of edible material ( 8 ) has a thickness substantially equal to the sum of the width of said flange ( 56 ) and of the annular mouth edge ( 66 ) of said wall ( 50 ) of the other half-shell ( 4 ).

9 . Package according to claim 1 , characterized in that said first ( 2 ) and second ( 4 ) half-shells of edible material are connected to each other by articulation means ( 52 ) integral with said half-shells.

10 . Package according to claim 1 , characterized in that said first ( 2 ) and second ( 4 ) half-shells are connected to each other by articulation means ( 52 ) integral with said half-shells and comprising a film hinge connecting facing portions of said flanges ( 12 , 16 ).

11 . Package according to claim 1 , characterized in that said first ( 2 ) and second ( 4 ) half-shell of non-edible material are connected to each other by articulation means ( 52 ) integral with said half-shells and comprising a film hinge ( 54 ) connecting facing portions of the annular mouth edge ( 66 ) of one of said half-shells and of said flange ( 56 ) of the other half-shell.

12 . Package according to claim 1 , characterized in that it further comprises an outer wrapping of sheet material formed by a first half-shell of sheet material ( 36 ) defining a cavity substantially complementary to the outer surface ( 30 ) of the half-shell(s) of edible material ( 8 ) and a second half-shell of sheet material ( 34 ) defining a cavity substantially complementary to the outer surface ( 28 ) of the half-shell of non-edible material with which the half-shell of edible material ( 8 ) is not associated, said first and second half-shells of sheet material being connected to each other along their respective edges so as to form a closed wrapping.

13 . Package according to claim 12 , characterized in that said first ( 36 ) and second ( 34 ) half-shell of sheet material have a peripheral end wall portion ( 40 b , 40 a ) in the form of a flange, wherein said peripheral portions are interconnected by gluing, welding, bending and/or crimping, or by a combination of gluing or welding with bending and/or crimping.
