Abstract: Apparatuses and devices for preventing heat transfer through fluids contained in a fluid container, a device of which includes an insulation system including a fluid container section for containing a liquid, a detachable insulation sleeve section for preventing heat transfer therethrough thereby maintaining temperature of the fluid contained within the fluid container, a lid section for preventing spillage of contents from the fluid container section, and optionally a straw for accessing those contents.

Abstract: Apparatuses and devices for preventing heat transfer through fluids contained in a fluid container are disclosed. The device comprises an insulation sleeve having at least one wall and a gripping ring having an inner surface configured to grip the fluid container and an outer surface configured to couple with an inner surface of the insulation sleeve. The insulation sleeve includes a first coupling mechanism and the gripping ring includes a second coupling mechanism. The first coupling mechanism and the second coupling mechanism are configured to couple with each other to snugly fit the insulation sleeve and the gripping ring over the fluid container.

Abstract: A cold water extraction system and method for preparing a beverage includes a cold water extraction chamber for brewing a beverage; an insulated beverage storage chamber for storing the beverage brewed in the cold water extraction chamber; a drip band for controlling flow of liquid between the cold water extraction chamber and the beverage storage chamber and a sealing cap configured to seal the beverage storage chamber.
