A dispensing device comprises a loading chamber (12), a dispensing chamber (14), located beneath the loading chamber, a gate or shutter movable between a first open position and a second closed position to allow selective communication of the loading chamber and the dispensing chamber. The device further comprises a first indicating means in the form of a first indicator member which is retainable in a first-retracted position when the gate or shutter is in the closed position and which is displaceable to a second, extended position when the gate or shutter is moved from the closed position to the open position. The device further comprises second indicating means (116) which is actuable to display a second visible signal to indicate that the first signal has been observed. |
