Abstract: An apparatus for storing, preserving and dispensing perishable and degradable food and goods having a rigid housing. At least one modular unit is removably disposed in the rigid housing for holding items. The modular unit has a storage unit and a drawer constructed such that when the modular unit is removed from the rigid housing coolant and partial vacuum are retained in the modular unit. The storage unit seals the drawer when the drawer is closed within the storage unit, such that when the drawer is opened coolant is retained between the storage unit and the rigid housing when the modular unit is disposed in the rigid housing.
