&39sanpou yoshi&39 means &39benefit for all three sides the seller,the buyer and society&lsquo. this is a screw cap system of a new generation which prevents leaking on impact and is highly childresistant. the cap is locked and unlocked by turning the ring under it in the same direction as to "close" the cap. opening the locked cap requires two actions in opposite directions. the system will largely help prevent possible seismic fires caused by overturning of plastic tanks of oil and contamination of solutions at the medical front, as well as leakage of beverage or cosmetics while carrying. source httpwww.gentlelock.net
