Claim 1
Independent Claim
208 words
Container, particularly for receiving foods or the like and for use in a baking oven or the like comprising an inner tray surrounded by an outer tray, said inner tray being at least partially formed from a heat-resistant plastic material which has been exposed to a high energy, electron or electromagnetic radiation to increase its resistance to heat exposure and which is capable of permanently withstanding a temperature of over 200° C. (oven temperature), said outer tray being made of a blank (1) at least partly joined to the inner tray (2), said blank having an outer fibrous material layer (16) and an internal plastic coating (17) and comprising a base part (4) and a plurality of walls (7, 8) separated from said base part by means of bend lines (5 and/or 6), said walls having edge strips (9 and/or 10) which engage a first surface of a rim (14) on said inner tray (2), said edge strips being separated from the walls by means of additional bend lines (11 and/or 12), said container further being characterized by said edge strips of two facing ones of said walls carrying extensions (20), and a cover (3) sealed to a second surface of said rim opposed to said first surface.
