Abstract: A heat sealed cold pack with a plurality of broken boarder pockets for both holding a substance with a high heat of fusion, such as gel refrigerant consistently throughout the cold pack and allowing the gel refrigerant to migrate throughout the gel pack. The volume of each pocket is variable in response to flexibility and cooling capacity. A two container system that integrates the cold pack.

Abstract: A closure for increasing the storage life of perishables, which comprises a material with heating or cooling properties; a closure chamber comprising a chamber wall configured to house the material with heating or cooling properties; a seal structure for sealing or engaging the closure chamber to a perishable storage container for controlling the temperature in a perishable storage container; a fastening system to secure the closure chamber on a perishable storage container allowing the material with heating or cooling properties to act on stored perishables. The closure may act as part of a closure system that contains the closure with or without the material; and the container that stores perishables and may accommodates the material with heating or cooling properties in many configurations.
