An induction heating apparatus heats content efficiently while measuring a temperature of the heated content accurately. The induction heating apparatus includes a can holder, a heating coil disposed around the can holder, and a temperature measuring unit. A resealable metal beverage can having a thread formed on a neck portion and a cap screwed onto the neck portion is held by the can holder. The can holder holds the metal beverage can in a manner such that the cap of the can inserted thereto is exposed on an axially upper side. The temperature measuring unit measures a surface temperature of the cap of the metal beverage can held in the can holder.

Induction heating apparatus for a beverage can

An internal pressure inspection apparatus for a sealed container having a can lid that is attached to any of an upper end and a lower end of a can trunk, and that is deformed by an internal pressure of the container. A laser sensor adapted to measure a distance from the can lid by irradiating the can lid is situated parallel to the can lid while being allowed to move relative to the can lid. The inspection apparatus integrates relative displacement values between a reference point closer to a center of the can lid than a seamed portion and other points closer to a center of the can lid than the reference point, and acceptability of the internal pressure is judged based on the value of integration.
