<p>This invention relates to a container made with a sheet material formed of several connecting superimposed layers forming a unitary body, of which the inner one (1) is adapted to contact the contents, while the outer one (5) has flameproof properties, that is it is capable of transmitting heat without burning allowing thus the container contents to be heated. An intermediate layer (3) works as a support, while other layers (2,4) are optional and work as connecting elements.</p> |
