               1. A vessel for breast milk preservation, the vessel comprising: 
            an outer container having an outer container coupler, an insulating structure comprising a double walled body having a first wall spaced apart from a second wall by a vacuum-sealed gap, and an outer chamber with an inner surface, wherein the outer container coupler comprises outer container threads positioned on the inner surface of the outer container, the insulating structure extends at least partially along the outer container threads, and the insulating structure and the outer container threads are part of a unitary structure of the outer container; 
                an inner container receivable at least partially within the outer chamber, the inner container having an inner container coupler comprising inner container threads; and 
                a connector having first connector threads, second connector threads positioned radially inward of the first connector threads, and third connector threads, wherein 
                the first connector threads and the third connector threads are complementary to and configured to engage the outer container threads, 
                  the third connector threads are reversed in orientation relative to the first connect threads, and 
                  the second connector threads are complementary to and configured to engage the inner container threads, 
                wherein, when the outer container threads are engaged with the first connector threads and the inner container threads are engaged with the second connector threads, the outer chamber is entirely enclosed within a liquid-proof barrier.
