Abstract
A container body is sealed by means of a lid made of a flexible sheet having an insulative property and an antenna made of an electrically conductive material which is laminated upon the lid. According to this construction, when the container body is exposed to microwaves within a microwave oven, microwave energy is concentrated at a position near the front end of the antenna and the microwave energy is converted into heat energy, whereby the lid is opened by means of the thus converted heat. The lid can thus be precisely partially melted so as to form an opening of a predeterminedly suitable size.
