A container and dispensing system is provided that includes a tamper resistant and sealable container with a child resistant latching mechanism. The container includes at least one hopper for storing a controlled substance or sensitive material, and includes a container unit locking lid with a locking mechanism that may be opened through manual manipulation or through the use of a key. In at least one embodiment, the locking mechanism is a flat spring locking device. A designated person, in the event of a pill container, a pharmacist, may control an optionally required key for removing the lid during refill operations. For other sensitive materials where tampering or unauthorized access is desired, such as a feed hopper, the owner of the container may retain control of the optional key.
