Abstract
A metering cap in which a first component of a flowable material is squeezed out of a cartridge (C) which can be emptied by means of a press (P). The main component flows through a feed line (8) to an outlet line (11) and, in the process, drives two rotors (31) seated in a metering chamber (9) in a housing (1). Gear wheels (34) are seated on the shafts (30) of the rotors (31), which mesh with each other and, in this way, form a gear pump (24). The gear pump (24) conveys an admixing component from an integrated container (18) through a second feed line (23) into the outlet line (11). At least two components can be admixed in a metered manner in an extremely exact ratio to each other by the metering cap of this invention.
