The invention relates to a dispenser for delivering portions of liquid to pasty substances, having a storage container and a pumping chamber, the pumping chamber having at least one valve, and having a delivery head which can be displaced relative to the storage container and the displacement of which allows the substance to be delivered, the delivery head further having formed in it a delivery channel with a delivery opening, which delivery opening can be closed by a closure part which is removable, but is held in captive fashion on the delivery head. In order to specify such a dispenser for delivering portions of liquid to pasty substances which is configured in an advantageous manner, in particular, in respect of a closure part, it is proposed that the closure part is a sliding part which also forms a delivery-channel portion and interacts with a fixed closure pin.

Dispenser for delivering portions of liquid to pasty substances, having a storage container and a pumping chamber, the pumping chamber having at least one valve, and having a delivery head which can be displaced relative to the storage container and the displacement of which allows the substance to be delivered, the delivery head further having formed in it a delivery channel with a delivery opening, which delivery opening can be closed by a closure part which is removable, but is held in captive fashion on the delivery head, characterized in that the closure part is a sliding part which also forms a delivery-channel portion and interacts with a fixed closure pin and has a sliding-action actuating portion, characterized in that the sliding part is seated on the delivery head such that it is accessible for an actuating finger. 2. Dispenser according to claim 1, characterized in that the sliding part can be actuated from the upper side of the delivery head. 3. Dispenser according to claim 1, characterized in that the sliding part has an upper-side sliding-action actuating portion which, in cross-section, extends at an angle to a skirt portion such that the inner surface of the skirt portion encloses an angle of less than 180° in relation to the sliding-action actuating portion. 4. Dispenser according to claim 1, characterized in that the sliding part forms the skirt portion within the delivery opening. 5. Dispenser according to claim 1, characterized in that the sliding-action actuating portion extends such that it engages over a center. 6. Dispenser according to claim 1, characterized in that the sliding part has one or two flank portions which run at an angle both to the skirt portion and to the sliding-action actuating portion. 7. Dispenser according to claim 1, characterized in that the sliding part has guide rails which are disposed on the flank portions and, in order to guide the sliding part, interact with accommodating means of the delivery head. 8. Dispenser according to claim 1, characterized in that the sliding part is biased into its closed position. 9. Dispenser according to claim 1, characterized in that the closure pin extends substantially axially and centrally into the delivery channel. 10. Dispenser according to claim 1, characterized in that the delivery channel extends within a tube portion integrally formed in the top of the delivery head. 11. Dispenser according to claim 1, characterized in that the closure pin is attached to the tube portion.
