PROBLEM TO BE SOLVED: To simplify the production line by suppressing an increase in plant and concurrently restrain the thermal energy consumption in the production line as low as possible, in a production line for manufacturing a container from a metal strip covered with a crystalline thermoplastic resin layer, when an apparatus for non-crystallizing the thermoplastic resin layer is installed. SOLUTION: Concerning an oven apparatus 1 for heating containers provided on the way to the production line for manufacturing containers from the metal strip coated with crystalline thermoplastic resin layer, along the direction of movement of a conveyor 4 for transferring containers which passes through an oven body 2, the inside of the oven body 2 is divided into a plurality of zones 2a, 2b, 2c having different temperatures and concurrently one 2c of a plurality of heating zones inside the oven body 2 comprises a heating zone for non-crystallizing the thermal plastic resin layer which coats the metal surface of the container and the other heating zones 2a, 2b comprise zones for the other heating process (for example, a lubricating agents removing process) required for the container production process except the non-crystallization.
