A metering pump for integration into a container includes a pump housing having a pump chamber, a pump inlet, and a pump outlet. The pump chamber is defined by a pump chamber base and an elastically deformable pump dome. The pump housing is composed of at least a first pump housing portion and a second pump housing portion. The pump dome is a part of the first pump housing portion and the pump chamber base is a part of the second pump housing portion. In one example, a container includes the metering pump and an associated product dispenser.
