- 15 - Abstract of the Disclosure A method for replacing gases during canning process, including the steps of continuously conveying open cans containing a liquid one after another in a horizontal direction, lifting a can in the middle of its horizontal movement up to a seamer, applying a lid to the opening of the can, carring out a seaming operation, and lowering the seamed can to be transfered to the next treatment. Steam or an inert gas are introduced into an open can containing a liquid in a slantwise direction from above the can when the can is lifted and while the surface of the liquid keeps an inclined state due to an abrupt halt of its horizontal movement, so as to fill a head space of the can with a proper amount of steam or the inert gas. A lid is sealed to the can immediately after the head space has been filled with steam or the inert gas, and the lid is crimped to the can. An apparatus for replacing gases during canning process is also disclosed. By these method and apparatus the gases in the head space of the can can be easily and unfailingly replaced with steam or the inert gas.
