Abstract: A system for maintaining a temperature within a cooler is disclosed. In one embodiment, the cooler can include an outer shell comprising an insulating material. The cooler can also include a temperature retention insert resting inside the outer shell. In another embodiment, the cooler can include an outer shell and an isolation chamber with one or more vertical support strips. In another embodiment, a cooler can comprise an outer shell with multiple grooves in the inner wall of the outer shell wherein the grooves can secure one or more temperature retention blocks.

Abstract: A system for maintaining a beverage temperature is disclosed herein. Specifically, a beverage container holder is disclosed. Such beverage container holder can comprise an inner layer that is substantially cylindrical, said inner layer having a substantially cylindrical aperture about its axis, such that said inner layer has an inner radius and an outer radius. Additionally, such beverage container holder can comprise a temperature retention material layer that at least partially surrounds said inner layer. Further, said beverage container holder can comprise an insulation layer that is substantially cylindrical and surrounds said temperature retention material. In one embodiment, said beverage container holder can further comprise an outer layer that is substantially cylindrical and surrounds said temperature said temperature retention material layer.
