The invention relates to a dispenser for a substance, comprising a housing (1), a reservoir (2), a metering valve (3), and an actuator (4). In known dispensers, the metering valve (3) is positively coupled to the actuator (4) via coupling means when the metering valve is activated for the first time

The invention relates to a dispenser for a substance, comprising a housing (1), a reservoir (2), a metering valve (3), and an actuator (4). In known dispensers, the metering valve (3) is positively coupled to the actuator (4) via coupling means when the metering valve is activated for the first time. The invention is characterized in that the coupling means can be activated by inserting a the reservoir (2) into the housing (1) and by the respective relative movement between the housing (1) and the reservoir (2) in the direction of insertion (E) thereby eliminating an idle movement after the insertion of the reservoir.

The invention claimed is: 1. A dispenser, in particular a metering dispenser for the administration of a semisolid or liquid substance, comprising a housing (1) encompassing a cover being mountable on a wall with a housing rear wall and a cover being pivotably connected herewith, a reservoir (2) being insertable into a container receptacle in a direction of insertion (E) in housing (1), a metering valve (3) disposed on the reservoir (2) being able to dispense a predetermined quantity of the substance by means of a stroke movement of a valve element and an actuator (4) disposed on the housing being capable of transmitting an actuating force to the valve element via at least one pressure element for actuating the metering valve (3), wherein the dispenser encompasses coupling means disposed particularly on the housing (1), said coupling means being capable of producing a positive connection between the valve element and the actuator (4) either directly or directly at least in the direction of movement of the valve element and being formed by at least one retaining edge (5) and at least one carrier (6) at least partially encompassing the retaining edge (5) with a carrier receptacle and wherein the coupling means are configured in such a manner that the retaining edge (5) engages with the carrier receptacle in response to an insertion of the reservoir (2) in the direction of insertion (E), characterized in that the container receptacle is disposed on the housing rear wall and that it can be inserted into the container receptacle after pivoting the cover of the reservoirs (2), wherein the coupling means encompass a threading aid being formed by a supply narrowing in the direction of insertion, which guides the retaining edge (5) into the carrier receptacle during the insertion movement of the reservoir (2).
