Impact Pressure and Rebound Height of Containers for Liquid Products Subjected to Impact Due to Dropping

摘要

The impact pressure and rebound height of new containers developed for liquid products subjected to impact loads due to free fall were investigated. Two types of containers were used. One consisted of a case made of transparent plastic plates and a liquid-packing bag made of transparent plastic films. The bag contained about 1,000 ml of water. The other was a case made only of transparent plastic plates. The case contained about 1,000 ml of water. The containers were subjected to impact due to free fall, and photographs of the containers were taken using a high-speed camera. The impact pressure was measured using a pressure sensor. Results indicated that the maximum impact pressure in the containers with the liquid-packing bag is lower than that without the bag. The rebound height of the containers with the liquid-packing bag is shown to be lower than that without the bag.
