Method of packing a temperature sensitive product
A method of packing a temperature sensitive product utilizes a temperature controlled product shipper that includes a phase change material bladder which can be filled at the point of packaging. The temperature sensitive product is contained within an product box or master case, which is in turn packed inside an insulated liner and an outer box. The PCM bladder fits between the master case and the insulated liner and is filled with a preconditioned flowable PCM at the point of packing just before closing the box for shipment.
1. A method of packing and shipping a temperature sensitive product contained in a product box for shipment comprising the steps of:
arranging a phase change material (PCM) bladder within an outer box wherein the PCM bladder is configured and arranged to receive and hold a flowable phase change material;
arranging the product box within the PCM bladder, whereby at least a portion of the PCM bladder extends over the product box;
filling the phase change material bladder with the flowable phase change material after the arranging a PCM bladder step and after the arranging the product box step;
closing the outer box; and
shipping the product.
2. The method of claim 1 wherein the step of filling the PCM bladder comprises the steps of:
removing a stopper received in a filling bung of a filling port on the PCM bladder;
filling the PCM bladder through the filling port; and
replacing the stopper.
3. The method of claim 2 wherein the steps of removing the stopper, filling the PCM bladder and replacing the stopper are completed with an automated filling head configured and arranged to engage the filling bung.
4. The method of claim 2 wherein the step of filling the PCM bladder further comprises the step of pumping the flowable phase change material from an on-site source to a filling head configured and arranged to engage the filling bung.
5. The method of claim 3 wherein the step of filling the PCM bladder further comprises the step of pumping the flowable phase change material from an on-site source to said automated filling head.
6. The method of claim 4 wherein the step of pumping the flowable phase change material comprises the steps of:
producing the flowable phase change material on-site; and
storing the flowable phase change material on-site.
7. The method of claim 5 wherein the step of pumping the flowable phase change material comprises the steps of:
producing the flowable phase change material on-site; and
storing the flowable phase change material on-site.
8. A method of packing and shipping a temperature sensitive product contained in a product box for shipment comprising the steps of:
arranging an insulated liner within an outer box;
arranging a phase change material (PCM) bladder within the insulated liner wherein the PCM bladder is configured and arranged to receive and hold a flowable phase change material;
arranging the product box within the PCM bladder, whereby at least a portion of the PCM bladder extends over the product box;
filling the phase change material bladder with the flowable phase change material after the PCM bladder is arranged in the insulated liner and after the product box has been arranged in the PCM bladder;
closing the insulated liner;
closing the outer box; and
shipping the product.
9. The method of claim 8 wherein the step of filling the PCM bladder comprises the steps of:
removing a stopper received in a filling bung of a filling port on the PCM bladder;
filling the PCM bladder through the filling port; and
replacing the stopper.
10. The method of claim 9 wherein the steps of removing the stopper, filling the PCM bladder and replacing the stopper are completed with an automated filling head configured and arranged to engage the filling bung.
11. The method of claim 9 wherein the step of filling the PCM bladder further comprises the step of pumping the flowable phase change material from an on-site source to a filling head configured and arranged to engage the filling bung.
12. The method of claim 10 wherein the step of filling the PCM bladder further comprises the step of pumping the flowable phase change material from an on-site source to said automated filling head.
13. The method of claim 11 wherein the step of pumping the flowable phase change material comprises the steps of:
producing the flowable phase change material on-site; and
storing the flowable phase change material on-site.
14. The method of claim 12 wherein the step of pumping the flowable phase change material comprises the steps of:
producing the flowable phase change material on-site; and
storing the flowable phase change material on-site.
