Patent number: 6103280Abstract: A self cooling beverage container or can. Different embodiments of a self cooling can are shown including the use of an endothermic reaction perhaps between ammonium nitrate and water. In another embodiment a volatile liquid is evaporated. In another embodiment water is maintained in a low pressure environment and allowed to boil. The vapour which is produced from the boiling water is absorbed by a desiccant maintaining the boiling process. The cooling process may be initiated by the pressure release of a carbonated beverage can during opening of the can.Type: GrantFiled: September 18, 1998Date of Patent: August 15, 2000Assignee: Bass Public Limited CompanyInventors: Stuart W.

Patent number: 5908649Abstract: An improved package is described for use in packaging a wide variety of products, and in particular perishable food and horticultural products. The products are placed within a container of the type which establishes a modified atmosphere environment therein and is cooled, as by placing the container in contact with a cooling element partially surrounding the container. The cooling element may hold liquid which is evaporated to enhance the cooling. The container and cooling collar may be subjected to vacuum cooling. The container may include a mechanism to enhance the bulk gas transfer rate during the application of the vacuum while still maintaining the desired atmosphere within the container. The container atmosphere may be precharged with gas of a desired composition. In addition, fumigants may also be included therein.Type: GrantFiled: September 4, 1991Date of Patent: June 1, 1999Assignee: Weyerhaeuser CompanyInventors: Stan Louis Floyd, Herbert Donald Muise, Mark A.
