Abstract: A packaged frozen food product is provided which is housed in a package which includes a first, substantially microwave permeable portion having a first frozen food component housed therein, and a second, microwave reflective portion having a second frozen food component retained therein. The package also includes a void space between the first frozen food component and the second frozen food component. Upon microwave heating, the first frozen food component will be thawed and the second frozen food component will remain substantially frozen.

Abstract: A closed pressurized container for producing a carbonated beverage of superior quality by providing for contact therein of water and a solid carbonation source. The pressurized container is designed to withstand the pressures and temperatures generated during the preparation of a carbonated beverage from a solid carbonation source. In a preferred embodiment, the container is a rigid receptacle in the shape of a wide mouth bottle adapted to receive a large cap or cover. A perforated basket is mounted inside the cover, and is accessible to water in the bottle when that vessel is turned upside down to an inverted position. A spring loaded, manually operated valve is provided in the cover to permit venting of carbon dioxide from the interior thereof after the water-based mixture within the container has become sufficiently carbonated by absorbing carbon dioxide released by contact of water with the solid carbonation source.

Abstract: A process for the preparation of carbonated beverages by the consumer is disclosed. Water is contacted with carbonated ice and, optionally, flavored syrup in a closed pressure vessel whereby superatmospheric pressure is created and a carbonated liquid is produced. Soft drinks prepared by this method have a degree of carbonation substantially the same as the bottled or canned product available commercially.
