Study of the Design for the Efficient Use of Pump-Type Cosmetics Containers

Pump-type containers are easy to use and also hygienic because the contents do not contact with the air. In this regard, pump-type containers are widely used from detergent to cosmetics. However, sometimes users have to throw the lotions away even if there is still remaining lotion in containers. Thus there is a need to take the measures against the pumptype containers that cause a waste. An experimentmeasuring the remaining content of the 2 types of cosmetics-shampoo and body lotionin containers after pumping the containers until nothing comes out of the containerswas conducted and the inner structure of containers was compared to identify the structural causes for the problems. The purpose of this study is to seek the effective design for pump-type cosmetics containers. A waste of cosmetics prompts customer complaint and also brings about environmental problems. The results of this study are estimated to make contribution to providing effective ideas to container makers, management of cosmetics brand companies and consumers.
