Abstract:
An apparatus for cooking food comprising:a. a tray comprising at least one sidewall bounded by a rim, said sidewall defining a tray interior; b. a heat seal attached to the rim and covering the tray interior; c. at least one vent positioned upon the rim of the tray, said vent creating a weakened portion on the heat seal; and d. a sleeve containing the tray therein, the sleeve including a sleeve top positioned snugly against the heat seal, thereby maintaining the heat seal and resisting pressure from within said tray interior during cooking, the sleeve further including at least one port aligned with said vent on the heat seal when the tray is retained within the sleeve, said port being only slightly larger than said vent, such that pressure from within said tray interior causes the heat seal to first rupture at said vent and aligned port.
