Abstract: Induction heating systems for metal food cans configured to deliver sufficient heat into the can to sterilize the food within the can are provided. The heating system includes an induction coil and a control system. The control system is configured to monitor and control heating of sealed food cans during induction heating and to control and/or confirm various aspects of can heating during induction heating.

Abstract: A system is provided for heating batches of sealed, metal cans containing a food product. The system includes a pressure chamber, an induction coil, a can support, a sealing device, a power supply, an air pressure source, and a drive. The pressure chamber has an opening. The induction coil is supported within the pressure chamber. The can support is for engaging and rotating a plurality of sealed, metal cans, at least a portion of the can support being movable through the opening from a first position outside of the chamber to a second position within the chamber adjacent to the induction coil and being rotatably supported within the chamber. The sealing device seals the pressure chamber when the can support is within the chamber. The power supply is coupled to the induction coil to energize the coil to apply an alternating current to the coil to induce a current into the metal cans which heats the food product of the metal cans.

Abstract: Embodiments of methods and apparatuses for providing a container with a lining are provided. A lining element is displaced into the interior of the container and coupled to the interior surfaces of the container to substantially cover the interior of the container.

Abstract: A can end and a tab configured to couple to the can end and a related method are provided. The can end is continuous. The tab is configured to couple to the can end with a post, which couples the tab to the can end without passing through the can end.

Abstract: A temperature changing container includes a plurality of walls joined to form an enclosure which seals contents of the enclosure within the walls. One of the walls includes a depression extending into the enclosure. Upon activation, chemicals at least partially disposed within the depression change temperature.

Abstract: An induction heating system configured to sequentially heat a plurality of filled and sealed food containers is provided. The system includes an induction heating coil defining a lumen having a longitudinal axis. The lumen is configured to receive the containers during heating, and the induction coil is configured to generate an alternating magnetic field causing resistive heating of the container. The system includes a container moving device configured to move containers into the induction heating coil lumen prior to heating, to move containers while within the induction heating coil lumen and to move containers out of the induction heating coil lumen after heating.

Abstract: A container including a sidewall and an end panel is provided. The end panel includes a center panel, an elastic portion, and a frustoconical transition portion. The center panel and the elastic portion are configured to transition between a first configuration and a second configuration.

Abstract: A temperature detection system for detecting temperature within a metallic can during heating is provided. The system includes an induction heating coil configured to generate an alternating magnetic field, and a hermetically sealed can positioned within the magnetic field generated by the induction coil. At least a portion of the sealed can is formed from a metallic material, and the sealed can includes a food product within the can. The magnetic field causes resistive heating of the metallic material of the sealed can. The system includes a temperature sensing element located within the sealed can configured to generate a signal indicative of the temperature of the food product during heating and a memory device communicably coupled to the temperature sensing element configured to store data related to the signal received from the temperature sensing element.

Abstract: A metal can for holding food during cooking is provided. The metal can includes a metal sidewall having an upper end, a lower end and a midpoint. The metal sidewall has an inner surface defining an interior cavity of the can configured to hold food during cooking. The metal can includes a metal can end coupled to the lower end of the sidewall and a metal insert located within the interior cavity of the can. The metal insert includes a planar disc and an upstanding insert sidewall extending from a peripheral edge of the disc portion, and a radially outward facing surface of the insert sidewall engages the inner surface of the metal sidewall.

Abstract: A container assembly includes a can, a can end, and a sheet which hermetically closes an access opening in the can end. The can end includes an opening for accessing the contents of the container. This opening is hermetically sealed closed by a sheet sealed to the end about the periphery of the opening with a closed-loop of adhesive. The sheet preferably includes a tab and a weakened or score line which causes the sheet to tear across the seal at an angle less than 90 degrees to the seal such that the sheet pulls away from the can end along a line generally parallel to the loop where the sheet is being separated from the can end.
