PCT No. PCT/SE96/01143 Sec. 371 Date Mar. 2, 1998 Sec. 102(e) Date Mar. 2, 1998 PCT Filed Sep. 13, 1996 PCT Pub. No. WO97/11342 PCT Pub. Date Mar. 27, 1997An oven and a vessel having a food-stuff or beverage in it cooperate to provide optimum operation of the oven to cook or heat the food-stuff or beverage. The vessel is dimensioned to fit within the oven and has an information carrier for indicating the temperature of the food-stuff or beverage within the vessel by changing color, and a separate identification marking. A detector within the oven detects the identification marking and activates a control device for the oven if at least one predetermined identification requisite from the identification marking is met. The identification marking preferably is a hologram which may be visible, or invisible, to the naked human eye. A separate non-temperature sensitive mark may be provided on the vessel and is sensed by a separate sensing device to allow the oven to start operation. |
