Title:
FOOD PACKAGING BODY FOR COOKING BY MICROWAVE OVEN
Document Type and Number:
Japanese Patent JP3062468
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To properly set a timing for the purging of steam which is generated from a food heat-cooked by a microwave oven, by a method wherein for a packaging body which is sealed by heat-sealing or the like, at one part of the sealed part, a whistle mechanism which generates a sound by a rapid passing of steam is provided.
SOLUTION: For a packaging body A which is constituted of a container main body 1 and a lid body 2, at a heat-sealed part 3, a whistle mechanism which is constituted of a reed 4 is provided. The reed 4 has a non-sealed part 4a, and is heat-sealed to the heat-sealed part 3 at both end parts 4b, and an outer peripheral edge part 5 which becomes a farther outer peripheral location than the non-sealsed part 4a is heat-sealed in a manner to be connected to the heat-sealed part 3. When a food is heated by a microwave oven under a state being sealed by the packaging body A, the outer peripheral edge part 5 is separated when the heat and the pressure of steam which is generated from the food have reached a specified level, and the whistle mechanism is opened. Then, the reed 4 vibrates and resonates when the steam rapidly passes the whistle mechanism, and a sound is generated, and the completion of the cooking is notified.
