A device for dispensing small quantities can be used for sensitive dispensing of powdered or granular substances in the gramm milligramme or microgramme range. The actual dispensing element consists of a teat (1) of the type fitted onto babies' bottles. A slit-like opening on the front of the tip (5) of this dispenser teat (1) forms the outlet (2) for the material. Said outlet can be made wider or narrower by exerting or relaxing the pressure on the sides of the tip (5). The substance which fills the dispenser teat is activated by means of an activator needle (6), the tip of which pierces the wall of the dispenser teat (1) just above the outlet (2) for the material and emerges below through the outlet (2) for the material. If larger amounts of substances are to be dispensed, the dispenser teat can be removably attached to a bottle containing the substance. |
