This present disclosure provides a vessel assembly for use in temperature sensitive shipping that can maintain a payload temperature across a range of temperatures. Importantly, the vessel assembly of the present disclosure reduces the overall packaging materials used in a shipper box and prevents the “wrong” mixture of PCM-containing vessels from being used. 1. A vessel assembly comprisinga vessel having a first filling port; anda bladder optionally having a second filling port;wherein the chamber of the vessel comprises a first phase change material; andthe bladder comprises a second phase change material.2. The vessel assembly of claim 1 , wherein the vessel comprises a rigid material.3. The vessel assembly of claim 2 , wherein the rigid material is a material selected from polyethylene claim 2 , polypropylene claim 2 , EVOH claim 2 , nylon claim 2 , fluorinated PE claim 2 , fluorinated PP claim 2 , PTFE claim 2 , a fluorinated polymer claim 2 , coextruded PE/Nylon claim 2 , PP/Nylon claim 2 , PE/EVOH and PP/EVOH.4. The vessel assembly of claim 1 , wherein the bladder comprises a flexible material.5. The vessel assembly of claim 1 , wherein the flexible material comprises a material selected from polyethylene claim 1 , polypropylene claim 1 , EVOH claim 1 , Nylon claim 1 , fluorinated PE claim 1 , fluorinated PP claim 1 , PTFE claim 1 , a fluorinated polymer claim 1 , coextruded PE/Nylon claim 1 , PP/Nylon claim 1 , PE/EVOH and PP/EVOH.6. The vessel assembly of claim 1 , wherein the first and second phase change material are selected from the group consisting of water claim 1 , paraffin wax claim 1 , alkanes claim 1 , alkenes claim 1 , fatty alcohols claim 1 , fatty acids claim 1 , fatty esters claim 1 , ethylene glycol claim 1 , propylene glycol claim 1 , eutectic mixtures claim 1 , and hydrated salt(s).7.
