Abstract
Shipping containers, and more particularly insulated shipping containers, for holding temperature sensitive products and coolant in a predetermined relationship to maintain a refrigerated or frozen condition for an extended period of time. Containers of this type can be molded from rigid polyurethane foam or other materials for shipping or transporting products such as biological and similar products which need to be maintained at 2° to 8° Centigrade or frozen. Specific constructions are shown and described.
Claims18
A shipping container for holding temperature sensitive products and a coolant in a predetermined relationship to maintain a refrigerated or frozen condition for an extended period of time, comprising
- a container having a base, four walls and a top, the base being capable of supporting a temperature sensitive product, and
- a removable coolant tray being disposable within the container above the product including a central pre-molded conduction block, and for receiving thereon coolant packages surrounding the conduction block.
A shipping container for holding temperature sensitive products and a coolant in a predetermined relationship to maintain a refrigerated or frozen condition for an extended period of time, comprising
- a container having a base, four walls and a top, the base being capable of supporting a temperature sensitive product,
- wherein the four walls interlock together, and further interlock with the base and top,
- interior surfaces of the walls include vertical grooves to provide predesigned air flow therein around the product via thermal convection to minimize temperature gradient with the product load, and
- a removable coolant tray being disposable with the container above the product, and for receiving thereon coolant packages, wherein the coolant tray includes a central pre-molded conduction block and for receiving coolant packages surrounding the conduction block.
A shipping container for holding temperature sensitive products and a coolant in a predetermined relationship to maintain a refrigerated or frozen condition for an extended period of time, comprising
- a container having a base, four walls and a top, the base being capable of supporting a temperature sensitive product, and
- a coolant tray disposable above the product and having a central pre-molded conduction block for controlling the temperature in a central area of the container and for receiving coolant packages surrounding the conduction block.
A shipping container for holding a temperature sensitive product and a coolant in a predetermined relationship to maintain a refrigerated or frozen condition for an extended period of time, comprising
- a container having a base, four walls and a top, the base being capable of supporting a temperature sensitive product, and the four walls interlock together and interlock with the base and top,
- four internal walls spaced within the container for surrounding the product and providing an air space between the container walls and these internal walls,
- a pad surrounding the top of the product to minimize tipping thereof, and
- a coolant tray with a central pre-molded conduction block.
A shipping container for holding temperature sensitive products and a coolant in a predetermined relationship to maintain a refrigerated or frozen condition for an extended period of time, comprising
- a container having a base, four walls and a top, the base being capable of supporting a temperature sensitive product, and
- wherein one or more interior surfaces include grooves to provide predesigned air flow therein around the product via thermal convection to minimize temperature gradient within the product load,
- two opposing walls have an internal “V,” “U” or similar shape to facilitate thermal convection within the container and around the product,
- two other opposing walls having coolant cavities to receive coolant packages, and
- a removable coolant tray being disposable within the container above the product, and for receiving thereon coolant packages, wherein the coolant tray includes a central pre-molded conduction block.
