Abstract: A device for cooling containers, for instance beverage bottles or beverage cans, arranged in a wrapping comprises a cooling-medium receptacle inserted or insertable within the wrapping, between the containers to be cooled, said receptacle being brought in surface contact with certain areas of the peripheral surface of the containers, due to a predetermined or bag-like shape. The components of a cooling mix have to be placed in the cooling-medium receptacle. The cooling-medium receptacle meant for one-time use and already containing the stable components, for instance the solid components, of the cooling mix is preferred. The cooling-medium receptacle prepared as mentioned can be placed in advance in a commercial package for filled containers, for instance beverage bottles or beverage cans. Before the use of the containers respectively the consumption of the beverages, it is required to add the reactive components after opening the package and then to reclose the cooling-medium receptacle.

Abstract: A device for thermally treating products, especially food and beverages, is provided with a thermal element improved in its heat-exchanging efficiency, which is brought into surface contact with the goods to be treated and the selection of a thermal medium suited to establish any desired temperature of the goods and can be charged into the thermal element. For this purpose, the heat-exchanger wall of the thermal element is built in wall sections in order to form a closed unit with the goods to be treated and the thermal element is kept in mutual surface contact and the remaining wall portions form together with the heat-exchanger wall a tightly closable container for the thermal medium having at least one filling and discharge opening, provided with an openable closing element for the thermal medium. The thermal element can be built with basically rigid walls, comprising wall portions fitting the shape of the goods to be treated.
