Abstract: To provide a sterilization method of container-packaged food which has a high effect on mixture food of solid food/soup and a filling system where all processes and devices can be simplified, a pre-seal lid material (PS), that has been cut to a dimension covering the opening of a cup filled with solid food, e.g. a dimension corresponding to the outer circumference of the flange of the cup, is fixed to a cup holder (CH) at a position for covering the cup opening by means of a holding bolt (31a) without being fusion bonded to the cup flange portion (CF), while a ventilation state between the head space of the cup and the air in a sterilization chamber is maintained. Thereafter, steam sterilization to the cup is performed in the sterilization chamber and the cup is transported to a clean box, filled with sterilized soup.

Abstract: A method and apparatus for manufacturing pressurized packages capable of obtaining gas displacement pressurized canned goods with high accuracy of internal pressure by atomizing liquid nitrogen, and supplying it together with low temperature vaporized gases to a head space of a can. A spray device assembly (10) for atomizing and spraying the liquid nitrogen is provided in an opening of the bottom of a liquefied gas storage tank (1) formed as a vacuum heat insulating structure. The spray device assembly (10) is constituted such that a valve (2) for controlling the flow rate of liquid nitrogen, a spray nozzle (3), a liquid nitrogen flowpassage (4) extending from the valve (2) to the spray nozzle (3), a nozzle cooling tank (5) for cooling the flowpassage, and a purge device for cutting an outer peripheral portion of a nozzle and an outlet portion off from the air, so as to prevent them from being frosted, are integrally mounted on a spray body 6.
