A dispenser for bulk goods comprises a storage container (11), and a discharge device connected thereto, a dosing means and a discharge chute (14) extending to a collecting point. The dosing means comprises a valve flap (18) which is pivotable between a closing position and a discharge position. An operating device (15, 27) is adapted to pivot the valve flap between said two positions. A locking device (34, 24) prevents the valve flap from pivoting from the closing position to the discharge position in the absence of a collecting receptacle or bag at the collecting point. Preferably, the operating device comprises two operating handles (15a, 15b), which are operatively connected to the valve flap (18) for pivoting thereof. In this operative connection, a sensor mechanism (27, 30, 31, 33) is included, which permits power transfer merely in essentially parallel or synchronous actuation of the operating handles.
