Claims Analysis

Total Claims: 16
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.
Claim 2
Dependent 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.
Claim 3
Dependent Claim 19 words

Claim 4
Dependent Claim 52 words
Container according to claim 1, characterized in that the inner tray (2) is shaped from polyethylene which has been exposed to said high energy, electron or electromagnetic radiation to increase its resistance to heat exposure and which is such that it can permanently withstand a temperature of over 200° C. (oven temperature).
Claim 5
Dependent Claim 20 words
Container according to claim 1, characterized in that the bend lines (5, 6 or 11, 12) have elongated slots (13).
Claim 6
Dependent Claim 22 words

Claim 7
Dependent Claim 21 words
Container according to claim 1, characterized in that the fibrous layer (16) is produced from cardboard or material containing recycled cellulose.
Claim 8
Dependent Claim 37 words
Container according to claim 1, characterized in that the inner tray (2) is made from a composite material, whose inner skin (19) is formed from a heat-resistant plastic material which comprises at least one crosslinked, thermoplastic material.
Claim 9
Dependent Claim 19 words
Container according to claim 7, characterized in that the inner skin (19) is surrounded by an outer skin (18).
Claim 10
Dependent Claim 22 words
Container according to claim 8, characterized in that further layers are placed between said inner skin (19) and said outer skin (18).
Claim 11
