PURPOSE: A dose pump, a manufacturing method thereof and a device thereof are provided to increase the productivity, and to cut down manufacturing cost by assembling the dosing pump quickly and completely. CONSTITUTION: A dose pump(1) is composed of plastic injection molded parts(2,3,4,5). A first plastic injection molded part is a pump housing with an integrally formed closure cap section(7) for placing the dose pump in a sealed manner onto a media store in the form of a container. A pump chamber of the dose pump is formed by a bellows-type spring, and a plate valve or disk valve is assigned to the bellows-type spring. A spray head is placed onto a discharge region of the bellows-type spring placed opposite to the intake region, and guided to travel with respect to the housing.
