Systems, devices, and methods relating to refrigerated packaging and temperature modulators

Abstract

Payload containers containing temperature modulators and coolant containers containing coolant movably coupled inside of an outer container are disclosed. In some aspects, exemplary temperature modulators may contain one or more solutions that directionally freeze when the product container is in contact with the coolant container, exerting force to push thermal conductors apart, which reduces air flow and thermal conduction from the coolant container to the payload container, thereby stopping the cooling of the payload container. According to further aspects, when the one or more solutions melt, the thermal conductors reconnect, reestablishing the cooling of the payload container. According to the implementations of the disclosed technology, such modulation may allow the payload to stay within safe temperature ranges.
