Example 1 : Model experiment of water infiltration into a container.
Request :
Cargo imported by food-processing company A from the USA suffered water damage. An inspection of the container did not disclose any problem with the container itself, nor was condensation observed. And so, the importer asked us to determine the cause.

Results :
The customer's cargo was placed on craft paper laid on the container bottom. Observation then disclosed that the ends of this craft paper became partially caught in the door packing. To confirm water infiltration under the same conditions, a water-spraying test was carried out using an empty container. The results confirmed that rain water infiltrated inside by capillary action through the craft paper caught in the door packing.

Example 2 : Proposal of double-doors for refrigerated containers to prevent temperature rise.
Request :
A food-trading company B had a problem in that the temperatures in pre-cooled containers would rise because the arrangement of the store prevented the containers' being placed so that they opened directly onto the inlet port of the cold store. Nevertheless, cargo was handled with the container doors kept open. We were asked to study the situation and work out a way to reduce the temperature rise.

Results :
It was proposed to add inside doors, which were easily handled, in the refrigerated containers. Comparative tests were carried out for conventional containers and the new ones with inside doors. The results proved that, in the containers with inside doors, the preset low temperature could be maintained without affecting cargo-handling efficiency.
