Novel lockable safe containers for dispensing valuable, dangerous and potentially dangerous goods via a main opening that is easy for adults (including the elderly or frail) to open, but difficult for children to open, using a finger pressure on a sliding closure with a deflectable extension operable by finger pressure to enable. The novel safe containers have many additional advantages including human factors, ergonomics, manufacturing, supply chain and distribution, warehousing, retail, tamper resistance advantages, and labeling. The slidable closure exits the main opening zone via an auxiliary opening but wholly without exiting the container in normal usage.
