Patent attributes
A metering unit for flowable solids including an outlet nozzle of flexibly elastic material having at one end an inlet opening for fixing on the outlet of a storage container and at its other end a slot-shaped outlet opening formed between two opposite sealing lips and elastically preloaded in the closed position and can be transferred against elastic preloading to an open position as a result of compressive forces. The slot-shaped outlet opening is elastically preloaded into its closed position by a separate clamp made from a flexibly elastic material, which can be applied releasably to the outer circumference of the sealing lips, wherein the legs of the clamp rest on the outside of the sealing lips in the mounted state and are elastically preloaded in the direction in which they are close together and can be moved elastically away from one another as a result of the compressive forces.
