ABSTRACT:
The device is based on a metering chamber which is designed to be screwed onto a tube and which has inlet and outlet openings for the product. The product is dispensed by a plunger displaceable in the metering chamber. An axially displaceable plate valve is arranged between the plunger and the bottom of the metering chamber. The valve plate is provided with holes for the passage of product. The plate valve functions such that the valve plate closes the outlet opening during filling of the metering chamber and the inlet openings during emptying of the metering chamber. The dispenser may be screwed onto standard commercial tube packs for the application of salves or pastes.
