Abstract

A device for dispensing grainy media, in particular pellets, from a storage space in a housing. The housing has a dispensing opening near the bottom thereof and can be closed by a hand-operated actuator. The actuator has a dosing chamber the internal end of which is closed in the dispensing position of the actuator relative to the storage space by a partition wall and whose dispensing end is aligned with the dispensing opening in the dispensing position. The size of the dosing chamber is substantially greater than the diameter of the pellets. The dosing chamber has a cover which adjacent the storage area forms an auxiliary dosing chamber. The auxiliary dosing chamber has a depth which is approximately equal to the diameter of a pellet and has upper flanks which converge toward one another and end in an upwarded direction notch, wherein the notch is narrower than the diameter of a pellet.
