Abstract: Devices and methods for storing and transporting substances. Such a device includes a base having a compartment for containing the substance, a lid closing the compartment and coupled to the base to selectively permit access to the compartment within the base, a cavity defined by the lid, the base, or at least in part a combination thereof, and an unlocking mechanism that immobilizes the lid relative to the base when the compartment is closed by the lid and releases the lid to enable the lid to pivot relative to the base to open the compartment. The unlocking mechanism is recessed within the cavity a distance from an opening of the cavity at an exterior of the device, and the unlocking mechanism is sufficiently recessed to be accessible with an adult's finger but not a child's finger.
