Abstract
The dispensing device for single use includes a multicomponent cartridge with a closure and a mixer. The cartridge and the mixer form an interconnected unit and the closure, arranged between the outlets of the cartridge and the inlets of the mixer, is configured as a valve arrangement in order to establish a connection between the cartridge outlets and the mixing elements of the mixer after performing a relative movement between the mixer and the cartridge or syringe. In certain embodiments of the invention the connection is effected by rotation of the mixing unit relative to the cartridge, and in other embodiments of the invention by axial displacement of the mixing unit relative to the cartridge. This results in a disposable dispensing unit that can be economically produced and is particularly easy to use.
