A device for metering a pasty product and mixing the same with a solvent has an exchangeable packing drum containing the pasty product and arranged in a dimensionally stable container, and a vacuum metering device arranged below the container. An outlet of the packing drum which extends through a bottom opening in the container is coupled to a product inlet of the metering device. In order to ensure in a reliable manner that the pasty product exits the packing drum only when the packing drum is coupled to the metering device, to avoid product coming in contact with service personnel, the outlet of the packing drum is designed as an outlet spout. A tubular spout holder is provided in the area of the product inlet, and is fitted with an inner cutting element. The cutting element pierces the seal material covering the free end of the outlet spout, as the latter is installed on the tubular spout holder.
