Abstract
A dispenser for distributing measured quantities of fluid to pasty product comprising a storage container with axially displaceable guide pistons and a dispenser head with a dispenser pump. A pump chamber is restricted by check valves at the entry and exit. A discharge channel is positioned downstream of the dispenser pump with an application opening that can be sealed by a sealing element. The dispenser head is designed with an application cap with a planar application surface closing the dispenser head in an axial direction and with an application opening centrally arranged in the application surface. The sealing element is designed in such a way, and arranged within the application surface, that the sealing element completely overlaps the application opening and is flush with the planar application surface.
