The invention relates to a container for packaging of the type that comprises a containment structure that is basically composed of a base wall (2) to which a rear wall (3), a pair of lateral walls (4) and a front wall (5) are attached and a closing element (6) where to the front wall (5) a valve (9) is attached that, in turn, is connected to an inflatable element (10) designed to contain dry ice (11). The container is designed to be operated from a rest condition, when it is inactive and no products are accommodated in the container, to a first operative condition in which there are some products in the container and in the front wall (5) there is the valve (9) with the inflatable element (10), and to a second operative condition in which the container is closed by the closing element and the dry ice expands, thereby enlarging the inflatable element that fills the remaining empty space inside the container, thereby blocking the closing element. |
