The invention relates to a dispenser (601, 2601, 2802), especially for dispensing solid preparations (225, 227), comprising a housing (603) having a dispensing orifice (606), and a collar member (609) having a receiving opening (604), and a passage member (605) having a receiving chamber (602), wherein the housing (603) and/or the passage member (605) are, preferably jointly, movable relative in respect to the collar member (609) between a first position with the receiving chamber (602) being in receiving communication with the receiving opening (604) of the collar member (609) and a second position with the receiving chamber (602) being in dispensing communication with the dispensing orifice (606) of the housing (603), wherein it is an object to provide a blocking interaction during which it is not possible to unscrew the dispenser from a container provided therewith. This object is achieved by a dispenser which is characterized in that the dispenser (601) comprises a locking element (650) which comprises a sleeve-like member (651) which is to be placed on the top of a container (617) and surrounds the dispensing orifice of the container (617), wherein the locking element (650) comprises two flexible elements (656) which in the attached position of the locking element (650) and the collar member (609) interact with blocking surfaces (658) provided at an inner wall of the collar member (609).
