<p>A packaging container comprises a holding container (11) formed by deforming a multi-layer sheet made of a resin according to a thermoforming method, a lid (13) made of resin and adapted for sealing the holding container (11), and an exterior covering surrounding the exterior of the holding container (11) and made of a non-metallic material having a hardness and a thermal insulating performance higher than those of the holding container (11). Since no metal is used in the packaging container, the packaging container can be easily crushed after being thrown away, and the collection of the packaging container can be made easier. Since the holding container (11) and the lid (13) are made of resin and the exterior covering is made of a non-metallic material, food in the packaging container can be directly heated by dielectric heating. According, the food can be heated to a sufficient temperature within a short time. Moreover, since the exterior covering has a good thermal insulating performance, the packaging container can be held by hand even immediately after being taken out from a vending machine, and the food held therein is prevented from quickly getting cold. <IMAGE></p> |
