Container designed to contain a product having to be heated by applying microwaves, the container having a side wall (10) and an end wall (12) formed by a base or a lid and means (10A) for limiting the penetration of the microwaves through the side wall (10), compared with the penetration of the mic
Container designed to contain a product having to be heated by applying microwaves, the container having a side wall (10) and an end wall (12) formed by a base or a lid and means (10A) for limiting the penetration of the microwaves through the side wall (10), compared with the penetration of the microwaves through a central region of the end wall (12). Advantageously, the container according to the invention further comprises means (12A) for concentrating the microwaves in a central region of the end wall (12), the said means being formed by an excess thickness of a dielectric material, the dielectric constant of which is at least equal to 1.5, preferably greater than 2.
