A dispenser for dispensing a viscous substance and tape. The dispenser has a housing with an interior. An intake channel, main conduit, and tape channel are located within the interior. The intake channel receives the viscous substance and is in fluid communication with the main conduit. A first outlet is coupled with the main conduit for dispensing the viscous substance. The tape channel has an elongate slot adjacent the first outlet for dispensing the tape. A piston is slidable within the main conduit between a closed position blocking the flow of substance from the intake channel into the main conduit and an open position allowing substance to flow from the intake channel into the main conduit. The piston is pre-tensioned biasing the piston to the closed position.
