Method of packaging thermally labile goods employing color-coded panels of phase change material
View Patent ↗A method of packaging thermally labile goods. The method includes the steps of (a) obtaining a legend correlating thermally labile goods with a PCM panel color, (b) locating the thermally labile goods to be packaged on the legend and identifying the correlated PCM panel color, (c) obtaining thermally conditioned panels of the correlated PCM panel color from amongst a plurality of differently colored thermally conditioned panels color coded in relation to the phase change temperature of the phase change material contained within the panels, (d) lining the retention chamber of a thermally insulated container with the obtained thermally conditioned PCM panels, (e) placing the thermally labile goods to be packaged into the lined retention chamber, and (f) closing the container.
1. A method of packaging thermally labile goods, comprising:
(a) obtaining a thermally insulated container defining a retention chamber;
(b) obtaining thermally labile goods to be packaged;
(c) obtaining a legend correlating listed thermally labile goods with a color;
(d) locating the thermally labile goods to be packaged on the legend and identifying the correlated color;
(e) obtaining thermally conditioned panels of the correlated color wherein the panels contain a phase change material and the panels are color coded in relation to the phase change temperature of the phase change material contained within the panels;
(f) lining the retention chamber with the obtained thermally conditioned panels;
(g) placing the thermally labile goods to be packaged into the lined retention chamber; and
(h) closing the container.
2. The method of claim 1 wherein the thermally insulated container has an outer shell of cardboard.
3. The method of claim 1 wherein the retention chamber is surrounded by thermal insulation.
4. The method of claim 1 wherein the retention chamber has a volume of about 300 cm 3 to about 200,000 cm 3 .
5. The method of claim 1 wherein the thermally labile goods to be packaged are a biological material.
6. The method of claim 5 wherein the thermally labile goods are at least one of human blood and a human blood product.
7. The method of claim 1 wherein the legend lists at least two different thermally labile goods correlated to at least two different colors.
8. The method of claim 1 wherein the legend lists at least three different thermally labile goods correlated to at least two different colors.
9. The method of claim 1 wherein the legend lists at least three different thermally labile goods correlated to at least three different colors.
10. The method of claim 1 wherein locating the thermally labile goods to be packaged on the legend comprises browsing a printed copy of the legend.
11. The method of claim 1 wherein locating the thermally labile goods to be packaged on the legend comprises browsing an electronic copy of the legend.
12. The method of claim 1 wherein locating the thermally labile goods to be packaged on the legend comprises performing a keyword search of an electronic database of the legend.
13. The method of claim 1 wherein the thermally conditioned panels may be selected from at least two different colors of panels having different phase change materials with different melt temperatures.
14. The method of claim 13 wherein the phase change materials are selected from at least two of H 2 O, D 2 O, ethylene glycol, propylene glycol and a mixture of H 2 O and glycol.
15. The method of claim 1 wherein the step of lining the retention chamber with the obtained thermally conditioned panels comprises surrounding the retention chamber with the panels.
16. The method of claim 1 comprising the additional step of repeating steps (a) through (h) for different thermally labile goods.
