The dispenser comprises a compressible elastomeric fluid conduit having a first end and a second end for flowing the fluid from the first end to the second end, a first check valve and a second check valve distanced in the conduit for forming a fluid chamber, and an actor for compressing the fluid chamber for dispensing a portion of the fluid. At least the second check valve is a duckbill valve. The second check valve is located at the second end of the conduit. The second check valve has sealing lips that extend beyond the second end of the conduit.
