## Abstract

A prepared meals system has at least one food container and cooking unit. The food container has at least two compartments for different foods to be heated at different temperatures and/or times. The cooking unit has at least one cooking station having two or more heating zones on a lower surface and at least one grilling element above the heating zones. The user selects one of several preprogrammed cooking procedures according to the indicia on a selected container having the desired food. A heat controller operates to control the times and temperatures of the heating zones and grilling element to appropriately cook the food in the container.

## Claims

### Claim 1

A prepared meals system comprising:
a plurality of heat-conductive food containers each of said containers being substantially identical form and each comprising at least first and second food-containing compartments for containing different foods having differing cooking requirements in accordance with a different one of a plurality of predetermined cooking procedures; and
a cooker unit for use with said food containers, said cooker unit comprising:
at least one cooking station configured to removably receive one of said food containers, said cooking station comprising:
a lower hotplate on which said one of said food containers rests, said hotplate having a plurality of heating zones, each of said heating zones lying beneath a respective one of said first and second food compartments of said one food container in use within said cooker unit, and each of said heating zones being individually actuable to facilitate differential conductive heating from below said first and second compartments of said one food container; and
a radiant heating element positioned above said hotplate, said radiant heating element being positioned to lie above one of said first and second compartments of said one of said food containers in use within said cooker unit whereby to grill from above the food in said one compartment without grilling the food in the other of said first and second compartments;
a controller capable of operating said heating zones and radiant heating element in accordance with a selected one of a plurality of predetermined programs which provide different heating and cooking actions for the food within the respective compartments; and
a program selector operable by a user to select the program required for the particular food container in use within said cooking station.

### Claim 2 (depends on 1)

A prepared meals system according to claim 1, wherein the cooker unit has a single said cooking station whereby the cooker unit can only accept a single said food container at a time.

### Claim 3 (depends on 1)

A prepared meals system according to claim 1, wherein the hotplate is of rectangular shape and comprises ribs along opposed lateral edges and a rear edge of the hotplate, whereby the container may be slid onto the hotplate from the front into a predetermined location on the hotplate.

### Claim 4 (depends on 1)

A prepared meals system according to claim 1, wherein the program selector operable by the user has discrete indicia for each respective program, and each of said food containers has indicia corresponding to that of the required program of the program selector.

### Claim 5 (depends on 1)

A prepared meals system according to claim 1, wherein the cooker unit has a plurality of said cooking stations, whereby the unit can accept a corresponding plurality of said food containers at a time, the controller being such that each cooking station can be separately controlled in accordance with a selected one of the predetermined programs.

### Claim 6 (depends on 5)

A prepared meals system according to claim 5, wherein the controller operates the respective cooking stations such that cooking finishes at substantially the same time in each of the cooking stations in use.
