Claim 1
Independent Claim
218 words
Food service tray made of plastic material having a top panel; at least one integral recess for receiving food formed in said top panel; a rim surrounding said top panel; a cut-out formed in said panel and located between the recess and a first side of the panel and substantially symmetrically with respect to opposite sides of the panel which are disposed laterally with respect to said first side, said cutout having an edge essentially parallel to the rim of said top panel and forming an essentially smoothly extending line; cutlery means arranged in said cut-out and forming an integral part of said tray; breakable attaching means retaining said cutlery means in the cut-out whereby, when the cutlery means are removed from the panel, the first side of the panel will form a handle for carrying the tray; and means to detachably secure a respective pair of identical food service trays in opposed and superposed relation, one relative to the other, so that a closed container is formed, said means comprising projecting engagement means and corresponding depressed engagement means, so that the projecting means of the one tray can be placed into jamming engagement with the depressed engagement means in the other tray, the adjacently located first sides of the oppositely placed panels forming a combined carrying handle.
Claim 2
Dependent Claim
218 words
Food service tray made of plastic material having a top panel; at least one integral recess for receiving food formed in said top panel; a rim surrounding said top panel; a cut-out formed in said panel and located between the recess and a first side of the panel and substantially symmetrically with respect to opposite sides of the panel which are disposed laterally with respect to said first side, said cutout having an edge essentially parallel to the rim of said top panel and forming an essentially smoothly extending line; cutlery means arranged in said cut-out and forming an integral part of said tray; breakable attaching means retaining said cutlery means in the cut-out whereby, when the cutlery means are removed from the panel, the first side of the panel will form a handle for carrying the tray; and means to detachably secure a respective pair of identical food service trays in opposed and superposed relation, one relative to the other, so that a closed container is formed, said means comprising projecting engagement means and corresponding depressed engagement means, so that the projecting means of the one tray can be placed into jamming engagement with the depressed engagement means in the other tray, the adjacently located first sides of the oppositely placed panels forming a combined carrying handle.
Claim 3
Dependent Claim
