Abstract: Devices are disclosed including a dispenser having a wall closing compartments of a container with an opening in the wall being moveable over a selected compartment, the compartments being preferably in angularly spaced relation about an axis on which the dispenser rotates. An engagement member is provided for engagement by one finger to release a lock device which normally securely locks the dispenser against movement relative to the container while the dispenser is engagable by another finger for movement thereof. In one embodiment, the lock device includes a lock bar carried by the dispenser and having outer end portions engageable in diametrically opposed slots in a ring carried by the container means. In another embodiment, a resiliently deformable element is carried by the container and has a portion engageable in angularly spaced slots of a projecting portion of the dispenser, such projecting portion also serving to journal the dispenser on the container.
