Packaging in flexible material for food products to be consumed after heating in the oven

Abstract

Packaging ( 10 ) in flexible material, comprising a supporting base ( 11 ) wherefrom two opposite side walls ( 12 ) rise up, each one sealed to a half-perimeter ( 13 ) of the base ( 11 ) and sealed one to the other along respective side edges ( 14 ) and along the upper edge with a head sealing ( 16 ), characterised in that in an intermediate area of the packaging ( 10 ) at least one continuous transverse sealing ( 17 ) is provided, suitable for dividing the interior of the packaging ( 10 ) into two separate chambers, a lower chamber ( 20 ) and an upper chamber ( 21 ), suitable for containing two different components of a product to be heated and brought into contact at the time of consumption, said transverse sealing ( 17 ) being such as to open when a certain pressure is reached in said lower chamber ( 20 ), thus forming a single chamber inside the packaging ( 10 ).

1 . Packaging ( 10 ) in flexible material, comprising a supporting base ( 11 ) wherefrom two opposite side walls ( 12 ) rise up, each one sealed to a half-perimeter ( 13 ) of the base ( 11 ) and sealed one to the other along respective side edges ( 14 ) and along the upper edge with a head sealing ( 16 ), in an intermediate area of the packaging ( 10 ) at least one continuous transverse sealing ( 17 ) being provided, suitable for dividing the interior of the packaging ( 10 ) into two separate chambers, a lower chamber ( 20 ) and an upper chamber ( 21 ), suitable for containing two different components of a product to be brought into contact at the time of consumption, characterised in that said transverse sealing ( 17 ) is such as to open when a certain pressure is reached in said lower chamber ( 20 ), following heating, thus forming a single chamber inside the packaging ( 10 ) and in that at a short distance from said upper or head sealing ( 16 ) a second transverse head sealing ( 18 ) is provided, and between said head scalings ( 16 ,  18 ) at least one side vent or opening ( 19 ) is provided, said second transverse head sealing ( 18 ) being such as to open when a certain pressure is reached in said unified chamber ( 20 ,  21 ). 
     
     
         2 . Packaging ( 10 ) according to  claim 1 , characterised in that said transverse sealing ( 17 ) has a V shape. 
     
     
         3 . Packaging ( 10 ) according to  claim 1 , wherein said at least one side vent or opening ( 19 ) is obtained by interrupting the corresponding side sealing ( 14 ) of the packaging in the area between said head sealings ( 16 ,  18 ). 
     
     
         4 . Packaging ( 10 ) according to  claim 1 , characterised in that on the side walls ( 12 ) of the packaging, approximately at the top of said chamber ( 20 ), respective weakening lines ( 22 ) of the material are provided, suitable for facilitating the opening of the packaging. 
     
     
         5 . Packaging ( 10 ) according to  claim 4 , characterised in that at least at one end of said weakening lines ( 22 ) a notch ( 23 ) is provided to facilitate the tearing, the depth of which does not exceed the width of the corresponding side sealing ( 14 ) of the packaging ( 10 ). 
     
     
         6 . Packaging ( 10 ) according to  claim 1 , characterised in that it is contained in a substantially rigid outer cardboard case ( 30 ) having a base ( 31 ) shaped as a tray and suitable for housing and supporting the flexible packaging ( 10 ), from which base two opposite side walls ( 32 ) rise up with width decreasing upwards, suitable for joining and covering the packaging. 
     
     
         7 . Packaging ( 10 ) according to  claim 6 , wherein said opposite side walls ( 32 ) of the outer cardboard case ( 30 ) are joined to said base ( 31 ) by means of respective pre-perforated lines ( 33 ), suitable for facilitating the removal thereof. 
     
     
         8 . Packaging ( 10 ) according to  claim 6 , characterised in that inside said cardboard case ( 30 ) disposable cutlery ( 34 ) is provided for consumption of the product. 
     
     
         9 . Kit comprising a packaging in flexible material for food products to be consumed after heating in the oven according to any one of the preceding claims, an outer cardboard ease ( 30 ) and disposable cutlery ( 34 ). 
     
     
         10 . Method of filling and use of the flexible packaging ( 10 ) according to any one of the preceding claims, comprising the following steps:
 insertion in the packaging open above of a first component suitable for positioning on the bottom of the packaging;   formation of said continuous transverse sealing ( 17 ) such as to divide the packaging into a lower chamber ( 20 ) and an upper chamber ( 21 );   insertion of a second component in said upper chamber ( 21 );   formation of the double head sealing ( 16 ,  18 ), leaving at least one side vent or opening ( 19 );   first step of heating of the packaging in the oven until opening of said transverse sealing ( 17 );   second step of heating until opening of said head sealing ( 18 ) and exiting of gases through said at least one side opening ( 19 );   opening of the packaging by breaking of said weakening lines ( 22 );   consumption of the product by means of the cutlery ( 34 ) optionally provided.
