Abstract

Abstract A pizza pie support includes a bottom panel generally contiguous with the pizza pie, and flap structures hinged to the marginal edges of said bottom panel about its circumference. An envelope of shrink film encloses the pizza pie and its support, and holds said flap structures against the marginal edges of the pizza pie. The bottom panel is perforated to permit heated air to contact the product.

Total Claims: 3
Claim 1
Independent Claim 175 words
A support for pizza pie and the like adapted to be enclosed in an envelope of shrink film, the support including: a generally circular bottom panel, spaced apertures in said bottom panel, a series of flaps hingedly connected to the periphery of said bottom panel about the circumference thereof, said flaps being spaced slightly apart by generally V-shaped notches a distance sufficient to remain spaced when said flaps are folded upwardly, said support being formed of paperboard coated with a coating capable of withstanding an oven temperature of 400* to 500* F and which is capable of preventing the pizza pie from sticking to said paperboard when subjected to such oven temperature, whereby when the pizza pie is enclosed in an envelope of shrink film, the shrinking of said film will fold said flaps upwardly about the edges of the pizza pie, and whereby when said shrink film is removed, said support bearing said pizza pie may be placed in an oven and said spaced apertures will permit circulation of heat through said pizza pie.
