A barrier is provided for the connecting pipe in order to prevent contamination of the connecting channel with said component, wherein the barrier means can be removed in order to dispense the multi-component mixture.

Abstract: The invention relates to a dispenser for dispensing an adhesive or sealant from a vessel, in particular from a pressurized vessel, via a valve. For this purpose, the dispenser is equipped with a lever with a grip region for actuating the valve. The dispenser also has an attachment, on which the lever is fitted in a pivotable manner, and an actuator with a supporting region for the lever. The actuator is configured such that it can be rotated relative to the attachment, and the supporting region is therefore variable, in order to change the effective lever path for the actuation of the valve, for activating or deactivating the dispenser or for varying the volume flow as product is dispensed.

Abstract: A device for receiving and dispensing a coatable material such as adhesive, glue, cosmetics and the like. A sleeve-shaped receiving element has a piston-shaped element carrying the coatable material that is displaceable in longitudinal direction by a screw spindle operated by an external rotary grip at the base of the receiving element. The underside of the piston-shaped element is formed to complement the inwardly protruding shape of the sleeve base or grip element, such that there is virtually no free space in which air can collect between the piston-shaped element and the sleeve base when the piston element is fully retracted in the receiving element. Thus the device avoids undesired bubble formation during the filling process, and undesired material break off during use can be largely excluded.

Abstract: A device for receiving and dispensing a coatable material comprises a sleeve-shaped receiving element in which is arranged a piston-shaped element displaceable in longitudinal direction and provided with an internal thread, the element carrying the coatable material and being displaceable by an externally operable socket-shaped rotary grip, wherein the rotary grip comprises a screw spindle co-operable with the internal thread of the piston-shaped element, the device being so improved that detaching of the coating material from the piston-shaped element is reliably avoided without impairing the sealing function.

Abstract: 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.
