<P>PROBLEM TO BE SOLVED: To provide a sealed container storing viscous liquid-like content such as yoghurt or the like in which the stored content is not jetted out of the container and not dispersed by inner pressure in the container due to development of fermentation of the stored content when the lid of the container is opened. <P>SOLUTION: The central part of a lid is punched with a hole, the hole is sealed in advance with a smaller second lid than the lid. At first, the second lid is opened before opening the lid to reduce the inner pressure within the container to make the inner pressure equal to the surrounding atmospheric pressure. <P>COPYRIGHT: (C)2007,JPO&INPIT |
