Abstract
A dispenser for granular material or liquid includes a dispenser housing attached to a granular material/liquid-holding container. The housing has a hemispherical distal end including an exit port and a curved linear slot. A spherical casing having a common inlet/outlet port and an attached lever arm riding in the slot is positioned in the distal end of the housing so that in a fill position a measured quantity of the granular material/liquid passes from the container and fills a predetermined volume or two incremental volumes within the casing. Upon hand and finger movement of the lever arm to a first or second position the casing is sealingly rotated to a dispense position with cessation of access of material from the container and with the casing inlet/outlet port then aligned for at least partially aligned with the housing exit port. The measured volume or volumes then flow from the casing by gravity. The dispenser is held in an at least partial inverted position during the fill and dispense modes of operation. A leaf spring, which is cocked upon rotating motion of the lever arm and casing, positively returns the casing and lever arm to the fill position when the lever arm is released by the user after dispensing such measured quantity of the material.
