Title:
PAPER CONTAINER
Document Type and Number:
Japanese Patent JP2023027879
Kind Code:
A
Abstract:
To provide a paper container that serves as a sheet for high-frequency cooking, with little risk of a heat-resistant film falling off after microwave cooking, and that eliminates the need to prepare another tray to catch oil or juices.SOLUTION: A paper container 1 includes a bottom surface portion 3, and side surface portions 5 connected from the bottom surface portion 3. The side surface portion 5 includes a directional change portion 11 that curves or bends in a direction surrounding the bottom surface portion 3, and the directional change portion 11 retains its shape by thermal compression molding of the high-frequency cooking sheet. The directional change portion 11 has a relatively rigid structure, and the shape thereof is stable before and after microwave cooking. Even if the heat-resistant film on a surface of the sheet for high-frequency cooking shrinks and peels off from a paper substrate during the microwave cooking, it is difficult to apply tension to the area afterward.SELECTED DRAWING: Figure 3
