Assembly for food product and method for heating said assembly

Abstract

The invention relates to a pack for a food product comprising a tray 1 with a lip 4, a side wall 3 and a bottom 2, a film 6 sealed all around the periphery of said tray, partly over the lip and over the top of the side wall, directly adjacent to said lip, and a food composition 5 contained in said tray, the film coming substantially into contact with the food composition.

1 . Pack for a food product comprising
 a tray with a lip, a side wall and a bottom,   a film sealed all around a periphery of the tray, partly over the lip and over the top of the side wall, directly adjacent to the lip,   a food composition contained in the tray, and   the film coming substantially into contact with the food composition.   
   
   
       2 . Pack according to  claim 1 , wherein the side wall of the tray makes an angle of between 1 and 5° Ma vertical plane of the tray. 
   
   
       3 . Pack according to  claim 1 , wherein the tray is constructed from a multilayer composite. 
   
   
       4 . Pack according to  claim 3 , wherein the thickness of the side wall of the tray is between 400 and 700 μm. 
   
   
       5 . Pack according to  claim 1 , wherein the material from which the film is made is a Surylin-EVOH-Surylin multilayer composite. 
   
   
       6 . Pack according to  claim 5 , wherein the thickness of the film is between 100 and 150 μm. 
   
   
       7 . Pack according to  claim 1 , wherein the food composition is selected from the group consisting of a refrigerated composition and a frozen composition. 
   
   
       8 . Pack according to  claim 7 , wherein the food composition is chosen from the group of compositions consisting of sauces, pasta, rice, potatoes, vegetables, meat, and fish. 
   
   
       9 . Pack according to  claim 8 , wherein the composition is in a sauce. 
   
   
       10 . Pack according to  claim 1 , wherein the wall of the tray is rounded along a length. 
   
   
       11 . Pack according to  claim 1 , wherein the food composition occupies a volume of between 30 and 97% of a volume of the tray. 
   
   
       12 . Pack according to  claim 1 , wherein the food composition is packaged under a vacuum of between 10 and 300 mbar. 
   
   
       13 . A method of heating a pack comprising:
 a tray with a lip, a side wall and a bottom, a film sealed all around a periphery of the tray, partly over the lip and over the top of the side wall, directly adjacent to the lip, a food composition contained in the tray, the film coming substantially into contact with the food composition comprising the steps of   placing the pack in a microwave device,   using microwaves to heat the pack,   heating is continued until the film deforms under the effect of the rise in pressure inside the tray and partially detaches over a section of the periphery of the tray, and   heating is continued.   
   
   
       14 . Method according to  claim 13 , wherein during heating, the deformation of the film allows the lip of the tray to rise. 
   
   
       15 . Method according to  claim 13 , wherein the heating time is between 30 seconds and 10 minutes.
